Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a novel beam structure. Background Art

[0002] Corrugated steel sheet is a cold-rolled steel sheet made of high-strength steel with anti-corrosion treatment on the surface. Corrugated steel sheet has the characteristics of high strength, light weight and good durability, and can meet the functions of building exterior walls, roofs, partitions, heat insulation and other functions. When corrugated steel sheet is used as industrial plant house panels and wall panels, in the case of no insulation requirements, the steel consumption per square meter is about 5 to 11 kilograms. When there is a requirement for insulation, mineral wool board, glass wool, foam plastics and the like can be used as insulation materials. Corrugated steel sheet is combined with concrete to make a composite floor slab, which can save wooden formwork and can be used as a load-bearing structure. At the same time, in order to strengthen the bonding strength between corrugated steel sheet and concrete, it is advisable to pre-weld studs on the steel plate or press bidirectional stiffening ribs.

[0003] In recent years, with the development of high-rise buildings and stadium-type buildings, steel structures have become the mainstream of structures. Floor slabs composed of corrugated steel plates and concrete, as a new type of floor slab structure, have been widely used in floor (roof) projects. It has the advantages of no formwork, simple and fast construction, and high cost performance. In the floor slab composed of corrugated steel plates and concrete, the corrugated plates are directly laid on the steel beams, and studs are used to weld the steel beams through penetration. The slip between the steel beams and the floor slab concrete is mainly resisted by the studs. However, during the construction of this floor slab, due to the structural reasons of the corrugated steel plates themselves, there are structural gaps at the overlap position of the steel beams and the corrugated plate crests themselves, which are prone to leakage when pouring concrete. The traditional practice is to use mortar to seal the crest gap position in advance before pouring concrete, and then pour concrete. However, this practice is prone to leakage as the concrete is vibrated, resulting in contamination of the corrugated plates, which is time-consuming and laborious to clean up. In addition, the alkalinity of concrete can easily cause rust on the corrugated plates and affect the appearance, which are all undesirable to those skilled in the art.

[0004] At present, in the prior art, the manufacture of beams is divided into cast-in-place beams, prefabricated beams, etc. according to the construction process. The construction process of cast-in-place beams generally includes the following steps:

[0005] 1. Preparatory work: including review of construction drawings, on-site measurement, preparation of materials and equipment required for construction, etc.

[0006] 2. Foundation construction: First, carry out foundation excavation, soil treatment and cushion layer laying. Then, build the formwork and support according to the design requirements.

[0007] 3. Steel bar installation: According to the requirements of the structural design, steel bars 55 are set and fixed in the formwork. The arrangement of steel bars 55 should meet the force requirements, and pay attention to maintaining the gap with the formwork to facilitate concrete pouring.

[0008] 4. Isolation layer setting: An isolation layer is set above the steel bars, usually covered with plastic film to prevent direct contact between the concrete and the steel bars.

[0009] 5. Pouring concrete: After the formwork and steel bars 55 are installed, the concrete pouring begins. The concrete can be prepared on-site at the mixing plant or after being transported to the site. During pouring, attention should be paid to controlling the pouring speed and height to avoid voids and holes.

[0010] 6. Vibration and curing: After the concrete is poured, a vibrator is used to vibrate the poured concrete to remove air bubbles and improve the compactness of the concrete. Then, the concrete is cured, including measures such as moisture retention, sunshade, wind prevention, and frost prevention, to ensure the strength and durability of the concrete.

[0011] 7. Formwork removal: After sufficient curing time and when the concrete reaches the design strength, the formwork can be removed. When removing the formwork, careful operation should be carried out to avoid damaging the beam body.

[0012] In summary, in the prior art, the splicing of profiled steel sheets is mostly fixed only with bolts and nuts, which makes it impossible to effectively seal the corners of the profiled steel sheet splicing, resulting in the phenomenon of grout leakage; moreover, the existing construction technology of cast-in-place beams requires formwork erection first, and after the concrete solidifies, formwork removal is required, increasing the process flow.

[0013] In view of this, how to overcome the defects existing in the prior art and solve the above technical problems is a difficult problem to be solved in this technical field. Summary of the Invention

[0014] The present invention aims to overcome the problems that effective sealing cannot be achieved between the steel plates 1 forming the beam 7, resulting in easy grout leakage; and the process of the traditional cast-in-place beam 7 requires formwork removal operation, leading to a cumbersome construction process for the cast-in-place beam 7.

[0015] The present invention is realized as follows:

[0020] Wherein, the portion where each of the corner connection units 200 is in contact with the corrugated steel sheet presents a shape that matches the corrugated steel sheet.

[0026] The third clamping die 207 presses another part of the full-wave steel plate that is outside the horizontal wave clamping area of the third bearing die 206 onto the wave surface on the vertical surface of the third bearing die 206, causing the full-wave steel plate to be bent at 90°;

[0027] The pressing die in the third stage includes a fourth pressing die 208 and a fourth bearing die 209. The cross-sections of the fourth pressing die 208 and the fourth bearing die 209 are trapezoidal waves. The fourth pressing die 208 and the fourth bearing die 209 press the parts on the horizontal and vertical planes of the 90° bent steel plate after the second pressing stage that are used for coupling with the profiled steel plate into trapezoidal waves to form the corner connector 2.

[0028] Preferably, the several-shaped connector 3 is pressed by a V-shaped groove die 300. The V-shaped groove die 300 includes a first pressing groove 3001 and a second pressing groove 3002. The two sides of the first pressing groove 3001 form a 90° angle, and the two sides of the second pressing groove 3002 form a 135° angle;

[0084] Embodiment 1:

[0085] The embodiment of the present invention provides a novel roof beam structure, as Figure 1 shown, including: steel plate 1, corner connector 2, channel-shaped connector 3 and T-shaped connector 4.

[0086] The steel plate 1 is a profiled steel plate, which constitutes the main structure of the roof beam. The channel-shaped connector 3 and the corner connector 2 are located at the splicing joint between the steel plates 1. The T-shaped connector 4 is fixedly connected to the inside of the steel plate 1 that constitutes the roof beam. In an actual application scenario, the profiled steel plate that constitutes the main structure of the roof beam can be an open profiled steel plate and a closed profiled steel plate. In the embodiment of the present invention, the profiled steel plate adopted is an open profiled steel plate, and its advantages are as follows: The open profiled steel plate adopts an opening design method. Compared with other types of profiled steel plates, the open profiled steel plate has a lighter weight. Using the open profiled steel plate can effectively reduce the self-weight load of structures such as buildings and bridges; The open profiled steel plate has undergone special processing techniques and structural designs, and has high strength and stiffness, enabling it to withstand greater loads and pressures; The opening design structure adopted in the manufacturing process of the open profiled steel plate can effectively reduce the material usage, realize the efficient utilization of steel, and achieve the purpose of cost reduction; The opening structure design of the open profiled steel plate makes it have good air permeability, and reduces problems such as water accumulation and air pressure aggregation in the open profiled steel plate, effectively improving the service life of the open profiled steel plate; The production and installation of the open profiled steel plate are relatively simple, simplifying the operation difficulty, and can effectively improve the construction efficiency.

[0087] The corner connector 2 is used to connect two perpendicularly spliced steel plates 1. The corner connector 2 is trapezoidal and wavy, and fits the shape of the steel plate 1.

[0088] By arranging the corner connector 2 and the L-shaped connector 52 at the splicing joint of the steel plate 1, the splicing joint of the steel plate 1 is effectively sealed, replacing the traditional bolt and nut closing method, and preventing concrete from leaking from the side seam of the steel plate 1 when pouring concrete; By arranging the T-shaped connector 4, it makes the splicing of the steel plate 1 to the casting mold simpler and more convenient; By using the profiled steel plate as the main structure of the beam 7, in the process flow of the cast-in-place beam, the operation of finally removing the formwork is omitted, saving the process and increasing the construction efficiency.

[0089] To more fully elaborate on the solutions provided by the embodiments of the present invention, the above-mentioned structures will be further elaborated in detail below.

[0090] In the processing method of the several-shaped connector 3, two iron sheets with a trapezoidal cross-section can be welded together. However, when processed by welding, there may still be gaps at the weld. Therefore, the processing method adopted in the embodiments of the present invention is die processing.

[0091] As Figure 2 and Figure 3 shown, the several-shaped connector 3 is pressed by a V-shaped groove die 300. The V-shaped groove die 300 includes a first pressing groove 3001 and a second pressing groove 3002. The two sides of the first pressing groove 3001 form a 90° angle, and the two sides of the second pressing groove 3002 form a 135° angle.

[0092] As Figure 3a , Figure 3b and Figure 3c shown, the several-shaped connector 3 is pressed by a V-shaped groove die 300. Specifically, in the first stage of pressing the several-shaped connector 3, the two shortest sides of the flat steel plate for manufacturing the several-shaped connector 3 are evenly divided into 6 segments. At this time, 5 lines can be obtained on the steel plate. The steel plate is placed above the second pressing groove 3002, so that the first straight line 307 of the steel plate is aligned with the midline of the second pressing groove 3002, and the lower pressing head 3003 is pressed down to bend the surfaces on both sides of the first straight line 307 into a 135° angle; similarly, the fifth straight line 311 of the steel plate is aligned with the midline of the second pressing groove 3002, and the lower pressing head 3003 is pressed down to bend the surfaces on both sides of the fifth straight line 311 into a 135° angle, obtaining a steel plate with both ends bent.

[0093] As Figure 3d and Figure 3e shown, the second stage of pressing the several-shaped connector 3 is to flip the steel plate with both ends bent obtained after the first stage of pressing, place the steel plate above the second pressing groove 3002, align the second straight line 308 of the steel plate with the midline of the second pressing groove 3002, press down the lower pressing head 3003 to bend the surfaces on both sides of the second straight line 308 into a 135° angle; similarly, align the fourth straight line 310 of the steel plate with the midline of the second pressing groove 3002, press down the lower pressing head 3003 to bend the surfaces on both sides of the fourth straight line 310 into a 135° angle, obtaining a several-shaped steel plate with a flat middle.

[0094] As Figure 3f and Figure 3g ​As shown in the figure, the third stage of pressing the several-shaped connecting piece 3 is to place the intermediate flat several-shaped steel plate obtained by pressing in the second stage above the first pressing groove 3001, align the third straight line 309 with the midline of the first pressing groove 3001, lower the lower pressing head 3003, and bend the surfaces on both sides of the third straight line 309 by 90° to obtain the several-shaped connecting piece 3. Among them, as Figure 3 shown, the two sides of the first pressing groove 3001 form a 90° angle, and the two sides of the second pressing groove 3002 form a 135° angle. The reason is that if the iron sheet is divided into 6 surfaces (from left to right are the first plane 301, the second plane 302, the third plane 303, the fourth plane 304, the fifth plane 305, and the sixth plane 306), the first plane 301 and the second plane 302, as well as the fifth plane 305 and the sixth plane 306, are bent at 135°. After extending the first plane 301 and the sixth plane 306, the angle between them is 90°; between the second plane 302 and the third plane 303, and between the fourth plane 304 and the fifth plane 305, bending at 135° can make the second plane 302 and the fifth plane 305 in a parallel state, and make the third plane 303 and the fourth plane 304 bent at 90° parallel to the outside of the steel plate 1, so that the four edges of the wall are standard 90° angles.

[0095] Currently, in the prior art, the way to seal the corner of two spliced steel plates 1 is mostly to directly weld the two steel plates 1 together. The defects of these two welding methods are that there may be gaps between the welding points of the steel plate 1, and the two steel plates 1 cannot be welded together as tightly as possible. There will also be gaps between each welding point, and there is a risk of slurry leakage during concrete pouring.

[0096] Therefore, the embodiment of the present invention provides a corner connecting piece 2 for splicing two steel plates 1, as Figure 4 shown, the corner connecting piece 2 includes two corner connecting units 200. Among them, the two corner connecting units 200 are respectively welded on two rectangular surfaces of a rectangular plate folded at a 90-degree angle; among them, the part of each corner connecting unit 200 that fits with the profiled steel plate presents a shape that fits with the profiled steel plate.

[0097] Specifically, as Figure 4a 、 Figure 4b and Figure 4cAs shown, each of the corner connection units 200 is formed by die pressing. The die includes a first carrying die 202 and a first pressing die 201. The troughs of the trapezoidal wave shape of the first carrying die 202 correspond to the crests of the trapezoidal wave shape of the first pressing die 201. The corner connection unit 200 obtained after being pressed by the first carrying die 202 and the first pressing die 201 is welded to a rectangular plate folded at a 90-degree angle. The gap between the corner connection unit 200 and the rectangular plate is welded and sealed by a trapezoidal steel plate 211.

[0098] According to the above solution, when two corner connection units 200 are connected together by welding to obtain the corner connector 2, if manual welding is used, its accuracy cannot be guaranteed. If the corner connector 2 is manufactured by die pressing, in this way, it can effectively prevent the possibility of slurry leakage due to gaps between solder joints, and there is no need for manual welding of the corner connector 2, reducing labor costs and increasing work efficiency at the same time. Therefore, as Figure 4d shown, the embodiment of the present invention also provides a corner connector 2 integrally formed by one-time die pressing. It can be easily seen from the figure that the integrally formed corner connector 2 has a stamping inclined surface 212. The thickness of the stamping steel plate before stamping is about 1 mm, while the thickness of the stamping inclined surface 212 after stamping is only 0.5 mm - 0.8 mm. Therefore, the corner connector 2 obtained by this pressing method is not suitable for application scenarios with strong pressure.

[0099] Therefore, in addition to the above processing scheme of the corner connector 2, Embodiment 1 of the present invention also provides a second pressing scheme for the corner connector 2.

[0100] As Figure 5 and Figure 6 shown, the corner connector 2 is integrally formed by die pressing a steel plate. The die in the first pressing stage includes a second pressing die 203 and a second carrying die 204. The stamping surfaces of the second pressing die 203 and the second carrying die 204 are wave-shaped, so that the second pressing die 203 and the second carrying die 204 can integrally press the flat steel plate for making the corner connector 2 into a full wave shape in the first pressing stage. Specifically, considering that if the steel plate is bent multiple times, the bent parts are extremely prone to fracture. To minimize the influence of this adverse factor, the highest and lowest points of this wave shape are arc-shaped.

[0101] After the steel plate is integrally pressed into a wave shape in the first pressing stage, the second pressing stage is to bend the wave-shaped steel plate at 90 degrees without destroying the wave shape of the steel plate. Therefore, as Figure 7As shown, the molds in the second pressing stage include a third pressing mold 205, a third bearing mold 206 and a third clamping mold 207. The horizontal surface of the third pressing mold 205 is a wave shape coupled with the third bearing mold 206; the vertical surface of the third bearing mold 206 adjacent to its horizontal surface is made with a wave shape consistent with the pattern; wherein, at the intersection of the vertical surface and the horizontal surface of the third bearing mold 206, the trough of the wave shape on the vertical surface is connected to the peak of the wave shape on the horizontal surface (such as Figure 7b In addition, the vertical surface of the third pressing die 205 is aligned with the plane where the third bearing die 206 has the wavy trough or slightly behind the plane where the trough is located; specifically, slightly behind the plane where the trough is located means that the vertical surface of the third pressing die 205 is 2cm-5cm away from the plane where the wavy trough is located. In order to prevent the steel plate from breaking at the junction of the horizontal and vertical surfaces of the third bearing die 206 during stamping, as shown in the dotted line frame, the vertical surface of the third pressing die 205 is aligned with the plane where the wavy trough is located of the third bearing die 206 or slightly behind the plane where the trough is located; specifically, slightly behind the plane where the trough is located means that the vertical surface of the third pressing die 205 is 2cm-5cm away from the plane where the wavy trough is located of the third bearing die 206. Figure 7c As shown, the intersection of the horizontal surface and the vertical surface of the third supporting mold 206 is rounded.

[0102] Among them, a part of the full-wavy steel plate pressed in the first stage fits with the wavy shapes on the horizontal planes of the third pressing mold 205 and the third bearing mold 206, so that a part of the full-wavy steel plate is clamped between the wavy shapes on the horizontal planes of the third pressing mold 205 and the third bearing mold 206; the third clamping mold 207 presses the other part of the full-wavy steel plate exposed outside the horizontal wavy clamping area of ​​the third bearing mold 206 toward the wavy surface on the vertical plane of the third bearing mold 206, so that the full-wavy steel plate is bent into 90 degrees. Specifically, the downward pressing angle of the third pressing mold 205 should be slowly and obliquely dropped from a position parallel to the steel plate to prevent the steel plate from breaking due to the sudden pressure.

[0103] After the second stage of pressing, the corrugated steel plate is bent at 90°. The third stage of pressing requires that the corrugated shape of the steel plate matches the shape of the corrugated plate. Figure 8 As shown, the pressing mold in the third stage includes a fourth pressing mold 208 and a fourth bearing mold 209, the cross-sections of the fourth pressing mold 208 and the fourth bearing mold 209 are trapezoidal and wavy, and the fourth pressing mold 208 and the fourth bearing mold 209 press the parts of the horizontal and vertical surfaces of the 90° bent steel plate after the second pressing stage for coupling with the corrugated steel plate into a trapezoidal and wavy shape to form a corner connector 2. Specifically, as Figure 8b As shown, an arc transition 210 is provided at the junction of the trapezoidal wave shape and the wave shape on one side of the steel plate to prevent the steel plate from breaking due to pressing. Figure 8cAs shown, the bending part of the corner connector 2 has been rounded.

[0104] In summary, the second pressing scheme of the corner connector 2 provided by the embodiment of the present invention has higher universality in the actual application scenario, and the risk of deformation and fracture due to pressure is also smaller.

[0105] Inside the steel plate 1 that is spliced into the main beam body, the steel plate 1 is connected by the T-shaped connector 4. In building materials, the main function of the T-shaped connector 4 is to connect and fix components to enhance the structural stability and load-bearing capacity. The specific functions are as follows: By virtue of the connection and support in the vertical direction, using the T-shaped connector 4 as a connector during the house construction process can effectively withstand the shear force and seismic resistance generated under external actions such as earthquakes, effectively improving the stability and seismic resistance of the overall house structure; The T-shaped connector 4 made of high-strength steel has high strength and rigidity, so that when it bears a large load, the structure at the connection remains stable and firm; The T-shaped connector 4 can be quickly connected by means of bolts, welding, etc., improving the construction efficiency; At the same time, due to the special T-shaped structure of the T-shaped connector 4, it is easier to achieve precise docking between components; The T-shaped connector 4 is usually connected in the vertical direction, and the special T-shaped structure reduces the space occupation, making it more suitable for connecting components in narrow spaces or sites; With its own high strength, the T-shaped component can be fixedly connected to other components by means of bolts or welding, etc., which can effectively resist pulling and slipping, improve the reliability of the connection structure, and provide a longer service life.

[0106] When the T-shaped connector 4 connects the steel plate 1, a steel bar 55 is arranged inside the T-shaped connector 4 as a tie member.

[0107] The main purpose of using the steel bar 55 for reinforcement in the middle of the T-shaped connector 4 is to increase the strength and stiffness of the connector and ensure the reliability and stability of the connection. The specific reasons are as follows: In the T-shaped connector 4, the steel bar 55 is used for reinforcement to enhance the lateral and longitudinal strength of the connector and increase its overall load-bearing capacity and compressive capacity; As a high-strength material, the steel bar 55 can achieve the transfer of load and improve the load-bearing capacity of the connector by effectively sharing the load; When the T-shaped connector 4 bears a horizontal load or a bending stress, the steel bar 55 is used to effectively resist bending of the connector, reducing the risk of deformation or damage of the connector; By reinforcing the T-shaped connector 4 with the steel bar 55, while improving the stiffness of the connector, the overall structural stability is also enhanced; In terms of bearing lateral forces generated by earthquakes or strong winds, the steel bar 55 enables the connector to have the ability to prevent the structure from cracking or being damaged, effectively improving the durability and reliability of the connection.

[0108] According to the pressing process of the above-mentioned corner connector 2, the material for manufacturing the corner connector 2 needs to be a material with high strength, high toughness and good ductility, and it is not easy to break after repeated bending. Therefore, the corner connector 2 is made of high-strength low-alloy structural steel or galvanized sheet; the steel plate 1, the L-shaped connector 52 and the T-shaped connector 4 are made of galvanized sheet. The use of high-strength low-alloy structural steel or galvanized sheet to manufacture the internal connector 5 and the corner connector 2 has the following advantages: high-strength low-alloy structural steel has a higher yield strength and tensile strength than ordinary steel, so that it can effectively reduce the material consumption of high-strength low-alloy structural steel at the same size, thereby achieving the purpose of reducing costs while meeting the structural strength, and providing more flexibility for design; high-strength low-alloy structural steel usually has good toughness, so that it undergoes plastic deformation without breaking when subjected to excessive loads. The use of high-strength low-alloy structural steel can effectively absorb impact loads and vibration loads, providing the component with better structural stability and overall component safety; high-strength low-alloy structural steel is relatively traditional Conventional steel has a high strength-to-weight ratio, which enables it to further reduce weight under the same structure, realize lightweight design of building structures, and reduce the load on foundations and supporting structures; galvanizing is an effective method to improve the corrosion resistance of steel in humid or corrosive environments. Galvanized sheet is a steel sheet with galvanized surface, which has excellent corrosion resistance. The use of galvanized sheet in building materials can effectively increase the service life of building materials and reduce maintenance and repair costs; both high-strength low-alloy structural steel and galvanized sheet have good plasticity, and can be changed into specific shapes by cold bending or heat treatment. The plastic high-strength low-alloy structural steel and galvanized sheet can better adapt to the complex structures and unique forms in buildings.

[0109] In addition to the above structure, in order to increase the strength of the upper edge of the beam, the novel beam structure also includes an L-shaped connector 52, which is fixedly connected to the upper edge of the steel plate 1. The L-shaped connector 52 plays a reinforcing role at the joint of the two steel plates 1, and can also be used to reinforce the edge of the steel plate 1 horizontally arranged on the top of the steel plate 1. In actual use scenarios, the L-shaped connector 52 can also connect two longitudinally placed steel plates 1. At this time, the inner side of the L-shaped connector 52 is connected to the outer side of the steel plate 1. When the L-shaped connector 52 reinforces the edge of the steel plate 1 horizontally arranged on the top, the outer side of the L-shaped connector 52 is connected to the inner side of the steel plate 1.

[0110] Specifically, the L-shaped connector 52, as a connector at the joint of two steel plates 1, has the following advantages: With its L-shaped structure, the L-shaped connector 52 can achieve efficient connection of different components, and at the same time, it is easier to install and disassemble, facilitating construction; The L-shaped connector 52 is usually made of high-strength steel, with high strength and stiffness, to bear most of the loads at the joint and maintain the stability and firmness of the joint; The L-shaped connector 52 provides connection support in the vertical direction, which can effectively prevent the components from displacing or tilting under external forces, achieving the purpose of increasing the overall structural stability and safety. When bearing earthquakes or other lateral forces, it exhibits excellent structural stability and safety; Compared with other connection methods with complex structures, the L-shaped connector 52 has lower usage costs and better economy, which is conducive to the wide application of the L-shaped connector 52 in construction and engineering projects; The L-shaped connector 52 adopts an angular structure, which is more firm when connecting components, effectively reducing the risk of the connector failing under large loads. At the same time, the L-shaped connector 52 can provide long-term stable connection with its L-shaped structure, ensuring the reliability and durability of the structure.

[0111] Embodiment 2:

[0112] Based on Embodiment 1 of the present invention, Embodiment 2 provides a new type of house wall structure, as Figure 9 shown, including: steel plate 1, internal connector 5, and bottom seal 6.

[0113] The steel plate 1 is a profiled steel plate, constituting the main structure of the shear wall. The internal connector 5 connects and fixes the steel plate 1 inside the steel plate 1, and the bottom seal 6 is located at the bottom of the steel plate 1 to seal the gap between the steel plate 1 and the ground.

[0114] In the actual use scenario, using profiled steel plates as the main structure of the shear wall has the following advantages: Profiled steel plates have high strength and rigidity. As the main structure of the shear wall, they can effectively bear horizontal loads, increasing the seismic resistance of the main structure and the stability and safety of the overall structure; By using profiled steel plates, different structures can be prefabricated according to standard sizes and fixed through rapid connection at the construction site, achieving the purpose of efficient construction and greatly shortening the project implementation speed; In the design process of the shear wall, as a thin-walled material, profiled steel plates can achieve high space utilization rate, providing more available area; Profiled steel plates have high plasticity. According to design requirements, profiled steel plates can be flexibly arranged and spliced to adapt to various building forms in the design process; Recycling the recyclable profiled steel plates can effectively reduce the impact of profiled steel plates on the environment, conforming to the concept of sustainable development.

[0115] As Figure 10As shown, the bottom closure 6 is bent at a 90° angle, with the side in contact with the ground being a horizontal plane and the vertical plane being a trapezoidal wave shape, which is in contact with the steel plate 1. The bottom closure 6 includes an internal closure 60 and an external closure 61. The internal closure 60 and the external closure 61 are jointly fixed to the bottom of the steel plate 1 to seal the gap between the bottom of the steel plate 1 and the ground.

[0116] According to the solution provided by the above content of the embodiment of the present invention, using profiled steel sheets as the main structure of the shear wall increases the stability and safety of the overall structure. And since the profiled steel sheets are made into standard sizes and prefabricated, it ensures the construction accuracy and connection accuracy. Only simple connection and fixation are required at the construction site, so the construction speed is relatively fast, and the total project duration can be shortened; as a thin-walled material, profiled steel sheets can achieve a higher room space utilization rate in the design of the shear wall, providing more available area; profiled steel sheets are easy to process and adjust shapes, and can be flexibly arranged and spliced according to design requirements to adapt to various irregular building forms; through the bottom closure 6 provided at the bottom of the steel plate 1, the bottom of the steel plate 1 is effectively sealed, effectively preventing concrete from leaking from the bottom of the steel plate 1 when pouring concrete; through the internal connectors 5 provided, the splicing of the steel plates 1 is made simpler and more convenient, and it also facilitates the erection of the steel bars 55 inside the shear wall, improving the construction efficiency.

[0117] In order to more completely elaborate the solution provided by the embodiment of the present invention, the above-mentioned various structures will be further elaborated in detail below.

[0118] To effectively seal the gap between the spliced steel plates 1, a several-shaped connector 3 is used as the closure. The two ends of the several-shaped connector 3 are completely in contact with the side edges of the steel plate 1, and the several-shaped connector 3 keeps the four sides of the wall 9 in a horizontal state, and there is no longer a gap between the walls 9 when splicing the walls 9. Therefore, the house wall structure further includes a several-shaped connector 3, and the several-shaped connector 3 is used to seal the gap between the spliced steel plates 1.

[0119] In the processing method of the several-shaped connector 3, two iron sheets with a trapezoidal cross-section can be welded together, but when processed by welding, there may still be gaps at the welds. Therefore, the processing method adopted in the embodiment of the present invention is die processing. The processing process of the several-shaped connector 3 has been elaborated in detail in Embodiment 1 of the invention, and will not be repeated here.

[0120] In addition, as Figure 9aAs shown, it is the structure of the wall 8 using the L-shaped connector 22 as a closure. The L-shaped connector 2 can replace the several-shaped connector 3 as the closure between the steel plates 1 and the steel plates 1. The L-shaped connector 22 has a lower cost, but its adaptability and sealing performance are slightly inferior compared to the several-shaped connector 3. As Figure 9b shown, it is Figure 9a a partial enlarged view of

[0121] In addition to the connectors between the external steel plates 1 and the steel plates 1, as Figures 11 - 14 shown, the internal connector 5 is one of the T-shaped connector 4, the square-shaped connector 51, the L-shaped connector 52, or the C-shaped connector 53.

[0122] Among them, the advantages of the T-shaped connector 4 are as follows: The T-shaped connector 4 is used for the mutual connection between components to form a stable structural framework, achieving an improvement in the overall structural stiffness and stability; The T-shaped connector 4 with a T-shaped structure can achieve load transfer and dispersion, enabling the frame structure to withstand more pressure and greater loads; The T-shaped connector 4 enables load transfer between the connected components through rigid connection components, thereby enhancing the strength of the structural framework; The T-shaped connector 4 prevents relative movement or sliding between components by virtue of its T-shaped structure, improving the stability of the frame structure; The T-shaped connector 4 can connect components of different shapes or types to meet the functional requirements of the structure. For example, at the connection of the beam 7 and the column 8, the T-shaped connector 4 can connect the beam 7 and the column 8 together to achieve the functions of load bearing and load transfer of the beam 7; The T-shaped connector 4 has the characteristics of standardization and normalization. Using the T-shaped connector 4 simplifies the construction process and realizes the improvement of project quality and project efficiency.

[0123] The advantages of the square connector 51 are as follows: The cross-section of the square connector 51 is usually square or rectangular, with a relatively simple structure, low production and processing difficulty. It can be fixed by four bolts, ensuring the stability and safety of the overall structure while providing stable connection and support. When connecting the square connector 51 with bolts, the installation process is simple and fast. Using fastening bolts not only saves the complex operations in the welding process but also reduces the energy consumption during the connection process and environmental pollution. The square connector 51 has a wider morphological adaptability and can be used for connecting different types of components. It is widely used in house construction. For example, it is used in the joint connection of beams 7 and columns 8, and the strengthening of the corners and edges of the frame wall. The square connector 51 has a simple structure and better flexibility, and can be customized and adjusted according to design requirements to meet the specific design requirements during construction. For example, according to different sizes or load conditions, the corresponding specifications or thicknesses of the square connector 51 can be selected. With its wide application range and good flexibility, the square connector 51 demonstrates excellent economic practicality during use, effectively reducing the production and processing costs. At the same time, due to its reliability and stability, the overall structure is more durable, effectively extending the service life of the house.

[0124] Specifically, the advantages of the L-shaped connector 52 are as follows: The L-shaped connector 52 is usually made of high-strength steel, with high strength and stiffness to withstand most of the loads at the connection and maintain the stability and firmness of the connection. The L-shaped connector 52 provides connection support in the vertical direction, which can effectively prevent the components from displacement or tilting under external forces, achieving the purpose of increasing the stability and safety of the overall structure. The L-shaped connector 52 can be connected by bolts or welding during the installation process, and the installation method is simple and fast, which can effectively improve the construction efficiency. Due to the special L-shaped structure of the L-shaped connector 52, it is easier to achieve precise docking between components. The L-shaped connector 52 connects different components in the vertical direction, reducing the occupation of the internal space of the house during the construction process. While improving the utilization rate of the internal space of the house, it is more suitable for erection operations in narrow sites. The L-shaped connector 52 fixed to other components by bolts or welding has high pull-out strength and anti-slip ability, ensuring the reliability of the overall structure of the house and increasing its service life.

[0125] Specifically, the advantages of the C-shaped connector 53 are as follows: The C-shaped connector 53 is usually made of high-strength steel, enabling it to have high strength and rigidity, and still maintaining the stability and firmness of the connection when bearing a large load; The C-shaped connector 53 is usually used to connect components in the horizontal direction, without occupying the internal space of the house, and can improve the utilization rate of the house space while realizing component connection in a narrow space; The C-shaped connector 53 can be connected to different components by means of bolts or welding, etc. The installation method is simple and fast, and due to the C-shaped structure of the C-shaped connector 53, it is easier to achieve precise docking between parallel components; The C-shaped connector 53 connected by bolts or welding can achieve fixed connection between components, and provide high anti-pull strength and anti-slip ability, effectively ensuring the connection reliability between parallel structures and effectively improving the service life between house structures; When using the C-shaped connector 53 for connection, it can be customized and adjusted according to design requirements to meet specific requirements. For example, when connecting parallel components with different cross-sectional sizes, the specification selection and thickness adjustment of the C-shaped connector 53 are carried out according to the actual situation to select the C-shaped connector 53 that meets the load conditions.

[0126] When the internal connector 5 is a T-shaped connector 4, a steel bar 55 is provided inside the T-shaped connector 4 as a tension member.

[0127] The bottom closure 6 includes an internal closure 60 and an external closure 61. In order to further ensure the closure effect of the internal closure 60, on the trapezoidal wavy surface of the internal closure 60, there is a horizontal plane between the trapezoidal wavy surface and the folded edge. The purpose of this horizontal plane design is to lengthen the length of the internal closure 60, thereby increasing the number of weld points inside the steel plate 1 of the internal closure 60, so that the internal connector 5 fits more firmly with the steel plate 1 and prevents concrete from leaking out.

[0128] For the external closure 61, the outer side of its vertical surface should be kept flat and perpendicular to the ground to ensure that the external closure 61 fits completely with the outer surface of the steel plate 1 and plays a closing role. In addition, the external closure 61 also provides a second closing effect for the bottom closure of the steel plate 1. If there is a gap between the internal closure 60 and the steel plate 1 and the concrete leaks out through the gap, the existence of the external closure 61 can still keep the concrete enclosed inside the steel plate 1.

[0129] Among them, the horizontal plane and the vertical plane of the bottom closure 6 are fixedly connected by welding.

[0130] Based on the structure of the bottom closure 6 described above, the material for manufacturing the bottom closure 6 should be a material with high strength, high toughness, and good ductility, which is not prone to breakage after repeated bending. The materials of the internal connecting member 5 and the steel plate 1 should have high strength, corrosion resistance, and light weight. Therefore, the bottom closure 6 is made of high-strength low-alloy structural steel or galvanized sheet, and the internal connecting member 5 and the steel plate 1 are made of galvanized steel.

[0131] Example 3:

[0132] On the basis of Embodiment 1 and Embodiment 2 of the present invention, Embodiment 3 of the present invention provides a novel column structure, as Figure 15 shown, including: a steel plate 1, a T-shaped connecting member 4, a channel-shaped connecting member 3, and a bottom closure 6.

[0133] The steel plate 1 is a profiled steel plate, which constitutes the main structure of the column 8. The T-shaped connecting member 4 is located inside the column 8 and connects the steel plate 1. The channel-shaped connecting member 3 is used to connect the splicing part of two steel plates 1. The bottom closure 6 closes the gap between the column 8 and the ground. In an actual application scenario, the main structure of the roof beam can be an open profiled steel plate and a closed profiled steel plate.

[0134] The bottom closure 6 is bent at 90°. The surface in contact with the ground is a horizontal plane, and the vertical surface is a trapezoidal wave shape, which is in contact with the steel plate 1. The bottom closure 6 includes an internal closure 60 and an external closure 61. The internal closure 60 and the external closure 61 are jointly fixed to the bottom of the steel plate 1 to block the gap between the bottom of the steel plate 1 and the ground. Specifically, the horizontal plane and the vertical plane are fixedly connected together by welding.

[0135] According to the solution provided above, by arranging the channel-shaped connecting member 3 and the bottom closure 6 at the splicing part of the steel plate 1, the splicing part of the steel plate 1 and the bottom of the steel plate 1 are effectively sealed, replacing the traditional bolt and nut closure method, preventing concrete from leaking from the gap of the steel plate 1 when pouring concrete; by arranging the T-shaped connecting member 4, it is more simple and convenient to splice the steel plate 1 when pouring the mold; by using the profiled steel plate as the main structure of the column 8, in the process flow of the column 8, the operation of finally removing the formwork is omitted, saving the process and increasing the construction efficiency.

[0136] In order to more completely elaborate the solution provided by the embodiments of the present invention, the above-mentioned various structures will be further elaborated in detail below.

[0137] In order to effectively seal the gap between the spliced steel plates 1, a type-J connecting piece 3 is used to seal the four edges of the column 8. The two ends of the type-J connecting piece 3 are completely attached to the side edges of the steel plate 1, and the type-J connecting piece 3 keeps the four sides of the column 8 in a horizontal state. When splicing the columns 8, there is no longer a gap between the columns 8. In Invention Embodiment 1, the processing method of the type-J connecting piece 3 has been elaborated in detail and will not be repeated here.

[0138] In addition, as Figure 15a shown, the type-J connecting piece 3 can also be replaced by an L-shaped connecting piece 52, which has a lower cost but is slightly inferior in adaptability and sealing performance.

[0139] The bottom seal 6 includes an inner seal 60 and an outer seal 61. In order to further ensure the sealing effect of the inner seal 60, on the trapezoidal wavy surface of the inner seal 60, there is a horizontal plane between the trapezoidal wavy surface and the folding edge. The purpose of this horizontal plane design is to lengthen the length of the inner seal 60, thereby increasing the number of solder joints between the inner seal 60 and the inside of the steel plate 1, so that the inner connecting piece 5 is more firmly attached to the steel plate 1 and prevent concrete from leaking out.

[0140] For the outer seal 61, the outer side of its vertical surface should be kept flat and perpendicular to the ground to ensure that the outer seal 61 is completely attached to the outer surface of the steel plate 1 and plays a sealing role. In addition, the outer seal 61 also provides a second sealing effect for the bottom of the steel plate 1 following the inner seal 60. If there is a gap between the inner seal 60 and the steel plate 1 and the concrete leaks out through the gap, the existence of the outer seal 61 can still keep the concrete sealed inside the steel plate 1.

[0141] Inside the steel plate 1 that is spliced into the main body of the column 8, the steel plates 1 are connected by T-shaped connectors 4. In building materials, the main function of the T-shaped connector 4 is to connect and fix components to enhance the structural stability and load-bearing capacity. The specific functions are as follows: The T-shaped connector 4 is used for the mutual connection between components to form a stable structural framework, achieving an improvement in the overall structural stiffness and stability; The T-shaped connector 4 with a T-shaped structure can achieve load transfer and dispersion, enabling the frame structure to withstand more pressure and greater loads; The T-shaped connector 4 enables load transfer between the connected components through rigid connection members, thereby enhancing the strength of the structural framework; The T-shaped connector 4 prevents relative movement or sliding between components by virtue of its T-shaped structure, improving the stability of the frame structure; The T-shaped connector 4 can connect components of different shapes or types to meet the functional requirements of the structure. For example, at the connection between the beam 7 and the column 8, the T-shaped connector 4 can connect the beam 7 and the column 8 together to achieve the functions of load-bearing and load transfer of the beam 7; The T-shaped connector 4 has the characteristics of standardization and normalization. Using the T-shaped connector 4 simplifies the construction process and improves the project quality and efficiency.

[0142] To enable the T-shaped connector 4 to play a better stress-bearing role, a steel bar 55 is provided inside the T-shaped connector 4 as a tie member. The main purpose of using the steel bar 55 for reinforcement in the middle of the T-shaped connector 4 is to increase the strength and stiffness of the connector and ensure the reliability and stability of the connection. The specific reasons are as follows: In the T-shaped connector 4, using the steel bar 55 for reinforcement achieves the purpose of enhancing the transverse and longitudinal strengths of the connector and increasing its overall load-bearing capacity and compressive capacity; As a high-strength material, the steel bar 55 can achieve load transfer and improve the load-bearing capacity of the connector by effectively sharing the load; When the T-shaped connector 4 bears horizontal loads or bending stresses, the steel bar 55 is used to enable the connector to effectively resist bending and reduce the risk of deformation or damage to the connector; By reinforcing the T-shaped connector 4 with the steel bar 55, while improving the stiffness of the connector, the overall structural stability is also enhanced; In terms of withstanding lateral forces generated by earthquakes or strong winds, the steel bar 55 enables the connector to have the ability to prevent the structure from cracking or being damaged, effectively improving the durability and reliability of the connection.

[0143] In actual application scenarios, such as Figure 16As shown, taking the T-type connector 4 as an example, the T-type connector 4 is assembled into a rectangle of suitable specifications by welding, and then the steel bar 55 is cross-welded and fixed with the internal connector 5 as a tensioning piece of the T-type connector 4, and then the round steel is bent into a buckle 54, and the bent round steel is welded to the inner side of the T-type connector 4 to fix the main steel bar. When the square connector 51, L-type connector 52 and C-type connector 53 are connected inside the beam-column wall, the processing flow is roughly the same as that of the T-type connector 4. The difference is that different internal connectors 5 are suitable for different tensioning pieces. For example, the C-type connector 53 is suitable for welding and fixing with flat steel, and the appropriate tensioning piece is selected according to the actual structure used.

[0144] According to the pressing process of the above-mentioned several types of connectors 3, the material for manufacturing the several types of connectors 3 and the bottom closure 6 needs to be a material with high strength, high toughness and good ductility, and it should not be easy to break after repeated bending. The material of the T-type connector 4 and the steel plate 1 should be strong, corrosion-resistant and light. Therefore, the several types of connectors 3 and the bottom closure 6 are made of high-strength low-alloy structural steel or galvanized sheet, and the T-type connector 4 and the steel plate 1 are made of galvanized steel.

[0145] The use of high-strength low-alloy structural steel or galvanized sheet to manufacture the several-type connector 3 and the bottom closure 6 has the following advantages: high-strength low-alloy structural steel has a yield strength and tensile strength higher than that of ordinary steel, which effectively reduces the material usage of high-strength low-alloy structural steel under the same size, thereby achieving the purpose of reducing costs while meeting the structural strength and providing more flexibility for design; high-strength low-alloy structural steel usually has good toughness, so that it undergoes plastic deformation without breaking when subjected to excessive loads. The use of high-strength low-alloy structural steel can effectively absorb impact loads and vibration loads, providing the component with better structural stability and overall component safety; high-strength low-alloy structural steel is better than traditional Conventional steel has a high strength-to-weight ratio, which enables it to further reduce weight under the same structure, realize lightweight design of building structures, and reduce the load on foundations and supporting structures; galvanizing is an effective method to improve the corrosion resistance of steel in humid or corrosive environments. Galvanized sheet is a steel sheet with galvanized surface, which has excellent corrosion resistance. The use of galvanized sheet in building materials can effectively increase the service life of building materials and reduce maintenance and repair costs; both high-strength low-alloy structural steel and galvanized sheet have good plasticity, and can be changed into specific shapes by cold bending or heat treatment. The plastic high-strength low-alloy structural steel and galvanized sheet can better adapt to the complex structures and unique forms in buildings.

[0146] In one embodiment, Figure 17As shown in the figure, the connection section between the top of the column 8 and the beam 7 can be strengthened by setting stiffeners 80. The top of the column 8 is made of a steel plate or profiled steel sheet with a thickness of 0.6 - 1.0 mm (the wave height of the profiled steel sheet is within 5 mm). The outside of the column 8 is strengthened with folded parts as stiffeners 80, and the material of the stiffeners 80 is a steel plate bending forming part with a thickness of 0.6 - 1.0 mm.

[0147] Secondly, as Figure 17 and Figure 17a shown, the connection method between the column 8 and the beam 7 can be flange connection. Specifically, when the beam 7 and the column 8 are connected, the flange folded part 81 on the beam 7 can adjust the installation error. The way to adjust the installation error is to set oval holes on the flange folded part 81. Before the screw that connects and fixes the beam 7 and the column 8 is fixed, the screw slides in the oval hole to adjust the installation error between the beam 7 and the column 8; when the beam 7 and the beam 7 are connected, the flange folded part 81 on the secondary beam can adjust the installation error. Among them, the flange folded part 81 is formed by bending a 1 - mm steel plate, and the specific dimension structure of the flange folded part 81 can be adjusted according to requirements.

[0148] Example 4:

[0149] On the basis of Invention Examples 1 - 3 of the present invention, Example 4 provides a structure for connecting beams, columns and walls of a house. As Figure 5 and Figures 11 - 14 shown, it includes: a corner connector 2 and an internal connector 5. The corner connector 2 and the internal connector 5 cooperate to connect the beam 7, column 8, and wall 9 structures of the house. Specifically, the main material of the beam 7, column 8, and wall 9 structures is profiled steel sheet. And the profiled steel sheets that form the beam 7, column 8, and wall 9 mentioned in Invention Example 1 of the present invention are all of the open - type profiled steel sheet type.

[0150] In practical application scenarios, the connection method between the internal connector 5 and the profiled steel sheet is welding connection or bolt connection. Welding can provide high strength and rigidity, and in some cases can increase the overall stability. Bolts, nuts and other connectors are used to bolt-connect the profiled steel sheet and the T-shaped steel. This method is usually applicable in cases where disassembly or adjustment is required, and assembly and disassembly can be carried out conveniently. Among them, the profiled steel sheet is a cold-rolled formed steel sheet 1 made of high-strength steel and its surface is treated against corrosion. The profiled steel sheet has the characteristics of high strength, light weight, good durability, etc., and can meet various functions such as building exterior walls, roofs, partition walls, heat insulation, etc. Using the structure of profiled steel sheets and concrete support beams 7, columns 8, and walls 9 can eliminate the need for wooden formwork and can be used as a load-bearing structure. After pouring concrete, there is no need to carry out the operation of removing the formwork shell, and the advantages of the thin-walled steel-concrete formwork-free formwork system are remarkable. First of all, using profiled steel sheets as building units makes the construction speed faster, simpler and more cost-effective. Secondly, the standardization of profiled steel sheets enables effective bonding of modules and reduces errors and waste during the construction process. In addition, the light weight of profiled steel sheet modules makes them easy to transport and assemble, and has less impact on the environment.

[0151] The corner connector 2 is formed by pressing a steel sheet 1 through a mold. The corner of the corner connector 2 is bent at 90°, and the bent surface of the corner connector 2 has a corrugated cross-section.

[0152] The internal connector 5 includes a T-shaped connector 4, a square connector 51, an L-shaped connector 52 and a C-shaped connector 53. The internal connector 5 contains fixed steel bars 55. The interiors of the T-shaped connector 4, the square connector 51, the L-shaped connector 52 and the C-shaped connector 53 are fixed by the steel bars 55. Specifically, the interiors of the T-shaped connector 4, the square connector 51, the L-shaped connector 52 and the C-shaped connector 53 can also be fixed by bracing with either a flat steel or a round steel.

[0153] Specifically, the T-shaped steel is a structural steel with a crossbar and a vertical bar, commonly used in building engineering for parts that bear longitudinal and lateral forces, such as beams 7, columns 8, etc. It has the characteristics of high strength and good rigidity, and can effectively support and bear weight; the square steel: The square steel is a structural steel with four equal angles, commonly used in manufacturing mechanical equipment, bridges, automotive parts, etc. It has the characteristics of strong compressive capacity, convenient transportation and installation, and can play a role in various engineering fields; the L-shaped steel is a structural steel with a 90-degree right angle shape, commonly used as a load-bearing member or connecting piece in building engineering. It can provide additional support and stability, and can be used for various types of structures, such as steps, door and window frames, etc.; the C-shaped steel, also known as channel steel, is a structural steel with a C-shaped cross-section, commonly used in manufacturing light steel structures and light wall support materials. It has the characteristics of light weight and convenient construction, and can provide appropriate strength and stability, suitable for fields such as buildings and billboards.

[0154] In the actual application scenario, the process of assembling the internal connector 5 with the profiled steel sheet is as follows: First, the T-shaped connector 4, square connector 51, L-shaped connector 52, and C-shaped connector 53 are welded and assembled into a square or rectangle with appropriate specifications for the structures of the beam 7, column 8, and wall 9. Then, the steel bar 55 is cross-welded and fixed with the internal connector 5 (different internal connectors 5 are suitable for different tie rods. For example, the C-shaped connector 53 is suitable for welding and fixing with flat steel, and the appropriate tie rod is selected according to the actual structure used). In addition to fixing the internal connector 5, a round steel bar is bent into a buckle 54, and the bent round steel bar is welded to the inner side of the internal connector 5 to fix the main steel bar 55. Here, the main steel bar 55 has a larger radius and higher strength compared to the steel bar 55 used to fix the internal connector 5. Manufacture multiple connectors of the same specification, insert the steel bar 55 into the buckle 54 in sequence, and use thin steel bars 55 to secondary bundle and fix the main steel bar 55 between the connectors.

[0155] According to the structural solution provided by the above scheme, through the set internal connector 5, T-shaped connector 4, square connector 51, L-shaped connector 52, and C-shaped connector 53, stable support can be provided when building the support frame, so that when pouring concrete, the bonding force between the profiled steel sheet and the concrete is large enough, and the stability of the cast steel sheet 1 concrete structure is good. Moreover, the specifications and sizes of the internal connectors 5 are unified, and the horizontal consistency as the support frame is relatively high, which is convenient for adjusting and correcting the support frame; through the set corner connector 2, the corners of the profiled steel sheet can be effectively sealed, effectively avoiding the phenomenon of slurry leakage when pouring cement after the profiled steel sheet is built.

[0156] In order to more completely elaborate the solution provided by the embodiments of the present invention, the above structures will be further elaborated in detail below.

[0157] Currently, in the prior art, the most common way to seal the corner of two spliced steel plates 1 is to use iron sheets for plug welding or directly weld the two steel plates 1 together. The drawback of these two welding methods is that when using a simple iron sheet for plugging, there may be gaps between the iron sheet and the steel plate 1 between the solder joints. The same is true for directly welding the two steel plates 1 together. It is impossible to weld the two steel plates 1 together as tightly as possible, and there will also be gaps between each solder joint, which poses a risk of concrete leakage during pouring. Or, a single-piece connector corresponding to the shape of the profiled steel sheet is used, and the two single-piece connectors are connected together by welding. Even though this method is an improvement compared to the previous two methods, the accuracy cannot be guaranteed when connecting by manual welding. Therefore, in the embodiments of the present invention, it is considered whether a corner connector 2 can be manufactured by die pressing. In this way, it not only effectively prevents the possibility of concrete leakage due to gaps between the solder joints, but also eliminates the need for manual welding of the corner connector 2, reducing labor costs and increasing work efficiency at the same time. The processing method of the corner connector 2 has been elaborated in detail in Embodiment 1 of the invention and will not be repeated here.

[0158] According to the pressing process of the above-mentioned corner connector 2, the material for manufacturing the corner connector 2 needs to be a material with high strength, high toughness, and good ductility, which is not easy to break after repeated bending. Therefore, the corner connector 2 is made of high-strength low-alloy structural steel or galvanized sheet.

[0159] The T-shaped connector 4, the square connector 51, the L-shaped connector 52, and the C-shaped connector 53 are made of galvanized steel.

[0160] Embodiment 5:

[0161] Based on Embodiments 1-4 of the present invention, Embodiment 5 of the present invention further provides a housing connector structure for preventing concrete leakage, as shown in Figure 2 , Figure 10 , Figure 13 . It includes: a bottom seal 6, a channel-shaped connector 3, and a steel plate 1; the steel plate 1 is a profiled steel sheet, serving as the main structure for splicing the housing beams 7, columns 8, and walls 9. The bottom seal 6 and the channel-shaped connector 3 seal the gaps between the steel plates 1 and between the steel plate 1 and the ground. Specifically, the connection methods of the bottom seal 6 and the channel-shaped connector 3 to the steel plate 1 are both welding. The shape of the profiled steel sheet is trapezoidal wave-shaped, and the shape of the steel plate 1 mentioned in the embodiments of the present invention is trapezoidal wave-shaped.

[0162] The bottom closure member 6 is bent at 90°, wherein the side in contact with the ground is a horizontal surface, and the vertical surface is a trapezoidal wave shape, in contact with the steel plate 1. The bottom closure member 6 includes an internal closure member 60 and an external closure member 61, and the internal closure member 60 and the external closure member 61 are fixed together at the bottom of the steel plate 1 to block the gap between the bottom of the steel plate 1 and the ground. Specifically, the horizontal surface and the vertical surface are fixedly connected together by welding.

[0163] The several-shaped connector 3 is used to connect the joints of two longitudinally placed steel plates 1. Specifically, in the processing method of the several-shaped connector 3, two iron sheets with trapezoidal cross-sections can be welded together, but there may still be gaps at the weld when processing by welding, so the processing method adopted in the embodiment of the present invention is mold processing. The processing method of the several-shaped connector 3 has been described in detail in the embodiment 1 of the invention, and will not be repeated here.

[0164] In addition, the L-shaped connector 52 plays a reinforcing role at the joint of the two steel plates 1, and can also be used to reinforce the edge of the steel plate 1 that is horizontally set on the top of the steel plate 1. In actual usage scenarios, when the L-shaped connector 52 connects two longitudinally placed steel plates 1, the inner side of the L-shaped connector 52 is connected to the outer side of the steel plate 1, and when the L-shaped connector 52 reinforces the edge of the steel plate 1 that is horizontally set on the top, the outer side of the L-shaped connector 52 is connected to the inner side of the steel plate 1. Specifically, the L-shaped connector 52 as a connector at the joint of the two steel plates 1 has the following advantages: the L-shaped connector 52 can achieve efficient connection of different components by virtue of its L-shaped structure, and it is also easier to install and disassemble, which is convenient for construction; the L-shaped connector 52 is usually made of high-strength steel, and has high strength and rigidity to meet the requirements of bearing most of the loads at the connection and maintaining the stability and firmness of the connection; the L-shaped connector 52 provides connection support in the vertical direction, which can effectively prevent the components from being displaced or tilted under external forces, thereby achieving the purpose of increasing the stability and safety of the overall structure, and exhibiting excellent structural stability and safety when subjected to earthquakes or other lateral forces; the L-shaped connector 52 has lower use costs and better economy than other connection methods of complex structures, which is conducive to the L-shaped connector 52 being widely used in construction and engineering projects; the L-shaped connector 52 adopts an angular structure, which is more firm when connecting components, effectively reducing the risk of failure of the connector when subjected to large loads, and at the same time, the L-shaped connector 52 can provide long-term stable connection by virtue of its L-shaped structure, thereby ensuring the reliability and durability of the structure.

[0165] According to the solution provided above, by means of the bottom seal 6 provided, the inner seal 60 and the outer seal 61 jointly seal the bottom of the steel plate 1, which can effectively block the bottom of the steel plate 1 and prevent concrete from leaking from the bottom of the steel plate 1 during concrete pouring; by means of the corner connectors provided, the joints of the steel plate 1 can be effectively sealed, replacing the traditional bolt and nut sealing method, and preventing concrete from leaking from the side seams of the steel plate 1 during concrete pouring.

[0166] In order to ensure the flatness of the inner surface of the steel plate 1 and the uniform pressure distribution after pouring cement inside the steel plate 1, the bottom seal 6 is trapezoidal and wavy, and the trapezoid bulges inward on the vertical surface of the bottom seal 6, while the outside of the vertical surface remains horizontal.

[0167] For the inner seal 60, when pouring concrete, the concrete falling from the top of the closed steel plate 1 will exert a huge pressure on the ground and the inner wall of the steel plate 1. If the trapezoid of the inner seal 60 bulges outward on the vertical surface, it may deform due to the huge pressure exerted by the falling concrete. If the inner seal 60 deforms, it cannot fully conform to the inner shape of the steel plate 1, and the concrete will escape along the gap between the inner seal 60 and the steel plate 1. In order to protect the inner connector 5 from being damaged by the impact force of the pouring concrete, the trapezoid is made to bulge inward on the vertical surface of the bottom seal 6.

[0168] In order to further ensure the sealing effect of the inner seal 60, on the trapezoidal and wavy surface of the inner seal 60, there is a horizontal plane between the trapezoidal and wavy shape and the folded edge. The purpose of this horizontal plane design is to lengthen the length of the inner seal 60, thereby increasing the number of solder joints between the inner seal 60 and the inside of the steel plate 1, making the inner connector 5 fit more firmly with the steel plate 1 and preventing concrete from leaking out.

[0169] For the outer seal 61, the outside of its vertical surface should be kept flat and perpendicular to the ground to ensure that the outer seal 61 is completely attached to the outer surface of the steel plate 1 and plays a sealing role. In addition, the outer seal 61 also provides a second sealing effect for the bottom of the steel plate 1 following the inner seal 60. If there is a gap between the inner seal 60 and the steel plate 1 and the concrete leaks out through the gap, the presence of the outer seal 61 can still keep the concrete sealed inside the steel plate 1.

[0170] According to the scheme mentioned in the above content, for the bottom and side seam connectors of the beams 7, columns 8, and walls 9 built to close the steel plates 1, for connecting the horizontally placed steel plates 1 and the longitudinally placed steel plates 1, the gaps at the joints should be closed with a suitable structure. Therefore, the embodiment of the present invention also proposes a design scheme for corner connectors 2. The shape of the corner connectors 2 and the manufacturing process will be specifically described below.

[0171] The house connector structure for preventing leakage of grout also includes a corner connector 2, which is used to connect the joint of the longitudinally placed steel plate 1 and the transversely placed steel plate 1, and both sides of the corner connector 2 are trapezoidal and wavy. The processing flow of the corner connector 2 has been described in detail in the embodiment 1 of the invention, and will not be repeated here.

[0172] According to the pressing process of the above-mentioned corner connector 2, the material for manufacturing the corner connector 2 needs to be a material with high strength, high toughness and good ductility, and it is not easy to break after repeated bending. Therefore, the corner connector 2 is made of high-strength low-alloy structural steel or galvanized sheet.

[0173] The several types of connecting pieces 3 and the steel plate 1 are made of galvanized plates.

[0174] The use of high-strength low-alloy structural steel or galvanized sheet to manufacture the internal connector 5 and the corner connector 2 has the following advantages: high-strength low-alloy structural steel has a higher yield strength and tensile strength than ordinary steel, which effectively reduces the material usage of high-strength low-alloy structural steel under the same size, thereby achieving the purpose of reducing costs while meeting the structural strength and providing more flexibility for design; high-strength low-alloy structural steel usually has good toughness, so that it undergoes plastic deformation without breaking when subjected to excessive loads. The use of high-strength low-alloy structural steel can effectively absorb impact loads and vibration loads, providing the component with better structural stability and overall component safety; high-strength low-alloy structural steel is relatively strong compared to traditional Conventional steel has a high strength-to-weight ratio, which enables it to further reduce weight under the same structure, realize lightweight design of building structures, and reduce the load on foundations and supporting structures; galvanizing is an effective method to improve the corrosion resistance of steel in humid or corrosive environments. Galvanized sheet is a steel sheet with galvanized surface, which has excellent corrosion resistance. The use of galvanized sheet in building materials can effectively increase the service life of building materials and reduce maintenance and repair costs; both high-strength low-alloy structural steel and galvanized sheet have good plasticity, and can be changed into specific shapes by cold bending or heat treatment. The plastic high-strength low-alloy structural steel and galvanized sheet can better adapt to the complex structures and unique forms in buildings.

[0175] Embodiment 6:

[0176] Embodiment 6 of the present invention provides a novel building construction system on the basis of Embodiments 1-5 of the invention, as follows Figure 9 and Figure 18 shown, including: beam 7, column 8, wall 9, internal connector 5, corner connector and bottom closure 6.

[0177] The main structures of the beam 7, the column 8 and the wall 9 are spliced by profiled steel sheets. The internal connector 5 connects the profiled steel sheets inside the beam 7, column 8 and wall 9. The corner connector is located at the splicing of the profiled steel sheets to connect two profiled steel sheets. The bottom closure 6 is located at the bottom of the beam 7, column 8 and wall 9 to close the gap between the profiled steel sheets and the ground.

[0178] Specifically, in the actual use scenario, using profiled steel sheets as the main structures of the beam 7, column 8 and wall 9 has the following advantages: The profiled steel sheets have high strength and rigidity. As the main structures of the beam 7, column 8 and wall 9, they can effectively bear the horizontal load, increasing the seismic resistance of the main structure and the stability and safety of the overall structure; By using profiled steel sheets, different structures can be prefabricated according to standard sizes and fixed through quick connections at the construction site, achieving the purpose of efficient construction and greatly shortening the project implementation speed; In the design process of the beam 7, column 8 and wall 9, the profiled steel sheet, as a thin-walled material, can achieve a high space utilization rate, providing more available area; The profiled steel sheet has high plasticity and can be flexibly arranged and spliced according to design requirements to adapt to various building forms in the design process; Recycling the recyclable profiled steel sheets can effectively reduce the impact of profiled steel sheets on the environment, which conforms to the concept of sustainable development.

[0179] The internal connector 5 includes a T-shaped connector 4, a square connector 51, an L-shaped connector 52 and a C-shaped connector 53. The internal connector 5 includes tension bars 55. The T-shaped connector 4, the square connector 51, the L-shaped connector 52 and the C-shaped connector 53 are internally connected and fixed by the steel bars 55.

[0180] In an actual application scenario, the process of assembling the internal connector 5 with the profiled steel sheet is as follows: First, the T-shaped connector 4, the square connector 51, the L-shaped connector 52, and the C-shaped connector 53 are welded and assembled into a square or rectangle with appropriate specifications for the structures of the beam 7, the column 8, and the wall 9. Then, the steel bar 55 is cross-welded and fixed with the internal connector 5 (different types of internal connectors 5 are suitable for different types of bracing members. For example, the C-shaped connector 53 is suitable for welding and fixing with flat steel, and the appropriate bracing member is selected according to the actual structure used). In addition to fixing the internal connector 5, a round steel bar is bent into a buckle 54, and the bent round steel bar is welded to the inner side of the internal connector 5 to fix the main steel bar 55. Here, the main steel bar 55 has a larger radius and higher strength compared to the steel bar 55 used to fix the internal connector 5. Multiple connectors of the same specification are manufactured, and the steel bar 55 is inserted into the buckle 54 in sequence. Between the connectors, the main steel bar 55 is secondarily tied and fixed with thin steel bars 55.

[0181] The corner connector includes the several-shaped connector 3 and the corner connector 2. The several-shaped connector 3 is used to connect the splicing part of two longitudinally placed profiled steel sheets, and the corner connector 2 is bent at 90 degrees to connect the splicing part of the longitudinally placed and horizontally placed profiled steel sheets.

[0182] Based on the solution provided by the above content of the embodiment of the present invention, using the profiled steel sheet as the main structure of the beam 7, the column 8, and the wall 9 increases the stability and safety of the overall structure. And since the profiled steel sheet is made into standard sizes and prefabricated, only simple connection and fixation are required at the construction site, so the construction speed is relatively fast, and the total project duration can be shortened; as a thin-walled material, compared with the traditional brick-concrete structure or the steel bar 55 concrete structure, the profiled steel sheet used as the outer shell of the shear wall is lighter in weight, reducing the influence of the building's own weight on the foundation, and a larger space utilization rate can be achieved in the structural design, providing more available area; the profiled steel sheet is easy to process and adjust its shape, and can be flexibly arranged and spliced according to the design requirements to adapt to various irregular building forms; through the bottom closure 6 provided at the bottom of the profiled steel sheet, the bottom of the steel sheet 1 is effectively sealed, effectively preventing concrete from leaking from the bottom of the steel sheet 1 during concrete pouring; through the internal connector 5 and the corner connector provided, the splicing of the steel sheet 1 is made simpler and more convenient, and the construction accuracy and the connection accuracy of the prefabricated components are improved, effectively ensuring the consistency of the component quality and improving the construction efficiency; in order to more completely elaborate the solution provided by the embodiment of the present invention, the above-mentioned various structures will be further elaborated in detail below.

[0183] Currently, in the prior art, the most common ways to seal the corner of two spliced steel plates 1 are to use iron sheets for plugging and welding, or directly weld the two steel plates 1 together. The drawbacks of these two welding methods are that when using only iron sheets for plugging, there may be gaps between the iron sheets and the steel plates 1 between the solder joints. The same is true for directly welding the two steel plates 1 together. It is impossible to weld the two steel plates 1 together as tightly as possible, and there will also be gaps between each solder joint, posing a risk of grout leakage during concrete pouring. Or, use a single-piece connector corresponding to the shape of the profiled steel sheet and connect the two single-piece connectors by welding. Although this method is an improvement compared to the previous two methods, the accuracy cannot be guaranteed when connecting by manual welding. Therefore, in the embodiments of the present invention, it is considered whether a corner connector 2 can be manufactured by die pressing. In this way, it not only effectively prevents the possibility of grout leakage due to gaps between the solder joints, but also eliminates the need for manual welding of the corner connector 2, reducing labor costs and increasing work efficiency at the same time. The processing method of the corner connector 2 has been elaborated in detail in Embodiment 2 of the invention and will not be repeated here.

[0184] In actual application scenarios, the function of the corner connector 2 is not only to connect the steel plate 1 to the steel plate 1, but also to connect the steel plate 1 to the ground, or to a structure in contact with the bottom of the beam 7, column 8, or wall 9 for bottom sealing. At this time, only one of the two bent surfaces of the corner connector 2 is trapezoidal and wavy, and the other is a flat surface, which is in contact with the ground or the bottom-sealing structure. Therefore, the bent surface of the corner connector 2 has a wavy cross-section. Specifically, when the corner connector 2 connects two steel plates 1 with perpendicular cross-sections butt-jointed, both surfaces of the corner connector 2 are wavy folded surfaces; when the corner connector 2 connects a horizontally arranged steel plate 1 and a vertically arranged steel plate 1, one surface of the corner connector 2 is a horizontal plane, and the other surface is a wavy folded surface. In addition, during the specific research process, according to the pressure distribution of the cement pouring, the length of the corner connector 2 at the bottom needs to be greater than the length of the corner connector 2 at the top. The longer its length, the more solder joints can be added, thereby making the connection between the corner connector 2 and the profiled steel sheet more stable and preventing concrete from leaking out from its bottom.

[0185] In order to effectively seal the gap between the spliced steel plates 1, in an alternative solution, an L-shaped connecting member 52 can be used for sealing. However, using the L-shaped connecting member 52 will cause concave notches to appear on the four edges of the column 8, which is not conducive to splicing. Moreover, when multiple columns 8 are spliced together, there are gaps between the columns 8, resulting in uneven stress on the columns 8 and posing a safety hazard. By using the several-shaped connecting member 3, no concave notches will appear on the four edges of the column 8. The two ends of the several-shaped connecting member 3 are completely fitted to the side edges of the steel plate 1, and the several-shaped connecting member 3 keeps the four sides of the column 8 in a horizontal state, and there are no longer gaps between the columns 8 when splicing the columns 8. Therefore, the house wall structure further includes a several-shaped connecting member 3, and the several-shaped connecting member 3 is used to seal the gap between the spliced steel plates 1. The processing method of the several-shaped connecting member 3 has been elaborated in detail in Invention Embodiment 1 and will not be repeated here.

[0186] The bottom sealing member 6 is bent at 90°. One side that fits the ground is a horizontal plane, and the vertical plane is trapezoidal and wavy, which fits the steel plate 1. The bottom sealing member 6 includes an internal sealing member 60 and an external sealing member 61. The internal sealing member 60 and the external sealing member 61 are jointly fixed to the bottom of the steel plate 1 to seal the gap between the bottom of the steel plate 1 and the ground.

[0187] The bottom sealing member 6 includes an internal sealing member 60 and an external sealing member 61. To further ensure the sealing effect of the internal sealing member 60, on the trapezoidal and wavy surface of the internal sealing member 60, there is a horizontal plane between the trapezoidal and wavy shape and the folding edge. The purpose of this horizontal plane design is to lengthen the length of the internal sealing member 60, thereby increasing the number of solder joints between the internal sealing member 60 and the inside of the steel plate 1, making the internal connecting member 5 fit more firmly with the steel plate 1 and preventing concrete from leaking out.

[0188] For the external sealing member 61, the outside of its vertical surface should be kept flat and perpendicular to the ground to ensure that the external sealing member 61 completely fits the outer surface of the steel plate 1 and plays a sealing role. In addition, the external sealing member 61 also provides a second sealing effect for the bottom sealing of the steel plate 1. If there is a gap between the internal sealing member 60 and the steel plate 1 and the concrete leaks out through the gap, the presence of the external sealing member 61 can still keep the concrete sealed inside the steel plate 1. Specifically, the horizontal plane and the vertical plane of the bottom sealing member 6 are fixedly connected by welding.

[0189] Based on the structures of the above-mentioned corner connector 2, channel-shaped connector 3 and bottom closure 6, the materials for manufacturing the corner connector 2, channel-shaped connector 3 and bottom closure 6 need to be materials with high strength, high toughness and good ductility, which are not easy to break after repeated bending. The materials of the internal connector 5 and the steel plate 1 should be of high strength, corrosion-resistant and light in weight; and the profiled steel sheet and the internal connector 5. Therefore, the profiled steel sheet and the internal connector 5 constituting the beam 7, the column 8 and the wall 9 are made of galvanized sheet; the corner connector and the bottom closure 6 are made of high-strength low-alloy structural steel or galvanized sheet.

[0190] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
