Description

Technical Field

[0001] This application relates to the field of building engineering, and in particular to a secondary structural system wall construction. Background Technology

[0002] Currently, the main systems used in public and civil buildings in my country are frame structures and steel frame structures, especially in multi-story and high-rise buildings. Similarly, in super high-rise buildings, frame structures have advantages such as good seismic performance and high economic benefits. Whether it is a concrete frame, steel frame or frame-shear wall structure, a large number of secondary structures are needed to realize the building layout.

[0003] Currently, the construction procedures for secondary structural systems are cumbersome and complex. In my country, secondary structural systems are broadly divided into two types: one is a system of masonry and concrete structural beams and columns, and the other is a precast panel system represented by ALC slabs. Concrete secondary structural systems require pre-reserved reinforcing steel and the casting of concrete to form structural columns, resulting in numerous construction steps and a long construction period. ALC slab secondary structural systems often use welded angle steel to fix the ALC slabs, resulting in a large amount of on-site welding. During installation, the ALC slabs also need to be cut to the appropriate size, leading to material waste. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a secondary structural system wall structure.

[0005] A secondary structural system wall structure includes a support frame, the support frame comprising: A plurality of longitudinal support members, each of which is parallel to the others and whose length is adjustable, and... A plurality of transverse connectors are provided, wherein the transverse connectors are located between two adjacent longitudinal supports, each transverse connector having an adjustable length and being perpendicular to the longitudinal support and fixed at any position along the length of the longitudinal support, and a masonry space for laying brick masonry is formed between two adjacent transverse connectors and two adjacent longitudinal supports.

[0006] By adopting the above scheme, the longitudinal supports and transverse connectors directly form a frame structure. The distance between the longitudinal supports and the spacing between the transverse connectors are adjustable, and the shape of the brickwork can be freely changed, avoiding material waste during the construction of the wall. The longitudinal supports and transverse connectors form an integrated frame structure, and the longitudinal supports and transverse connectors can be prefabricated with sufficient strength to support door and window openings. There is no need to pour concrete to form structural columns, which simplifies the process of constructing the secondary structural system wall and improves construction efficiency.

[0007] In one embodiment, the transverse connector includes a sleeve and a telescopic beam sleeved at any position within the sleeve. The telescopic beam is exposed in the sleeve, and a fixing member is provided at one end of the sleeve. The fixing member has a "T" shaped cross-section and includes a fixing plate and a mounting plate perpendicular to the fixing plate. The fixing plate is fixed to the side of the longitudinal support member, and the mounting plate is fixed to the telescopic beam.

[0008] By adopting the above scheme, the telescopic beam can be adjusted to expose the sleeve at any length, thereby controlling the overall length of the beam. The fastener is used to fix the longitudinal support and the transverse connecting parts vertically.

[0009] In one embodiment, the fixed plate has a U-shaped cross-section and first mounting grooves on both sides. The longitudinal support member has multiple threaded holes arranged in an array along its length, and a first mounting bolt passes through both the first mounting groove and the threaded holes.

[0010] By adopting the above scheme, the first mounting bolt simultaneously engages with the first mounting groove and the threaded hole, enabling the fastener to be fixed at any position on the longitudinal support, thereby making the installation position of the crossbeam adjustable.

[0011] In one embodiment, the longitudinal support member is provided with a reinforcing plate, the reinforcing plate including a partition and support plates formed on both sides of the partition, the partition extending along the length direction of the longitudinal support member, and the end of the support plate opposite to the partition being fixed to the inner wall surface of the longitudinal support member.

[0012] By adopting the above scheme, when the brick masonry is in rigid contact with the longitudinal support, and when the brick masonry expands and contracts with temperature, the brick masonry will compress the longitudinal support, thereby causing the column to deform and reducing the mechanical properties of the column. The reinforcing plate is used to strengthen the structural strength of the longitudinal support.

[0013] In one embodiment, a buffer body is provided between the brick masonry and the longitudinal support member, and a discharge chute is provided on the side of the longitudinal support member facing the transverse connector. The support plate is inclined downward and its plane is connected to the lower side of the discharge chute.

[0014] By adopting the above scheme, the buffer body plays a buffering role between the brick masonry and the longitudinal support. Since it is difficult to keep the gap between the brick masonry and the longitudinal support uniform, the middle area is difficult to be covered by the filler of the buffer body. By setting the discharge chute, during the brick masonry stacking process, structural adhesive and other fillers can be injected into the longitudinal support through the threaded hole. Under the action of gravity, the filler flows out along the support plate and then flows to the space between the longitudinal support and the brick masonry.

[0015] In one embodiment, the longitudinal support member has multiple tie angle irons arranged in an array along the length direction on the side facing the transverse connector. The tie angle irons have an "L" shaped cross-section, and the short side of the tie angle iron is fixed to the longitudinal support member while the long side is sandwiched between two adjacent brick masonry pieces.

[0016] By adopting the above scheme, since the bottom brickwork is more likely to bear a large load, the tie angle iron can distribute part of the load between adjacent brickwork to avoid excessive load on the blocks and cause cracks.

[0017] In one embodiment, the contact surface between the tie angle iron and the discharge trough is provided with a second mounting groove, the second mounting groove being perpendicular to the discharge trough.

[0018] By adopting the above scheme, during the installation process, the internal expansion bolts are simultaneously inserted into the discharge slot and the second installation slot, which can achieve the fixation between the tie angle iron and the longitudinal support, and the installation position of the tie angle iron can be finely adjusted.

[0019] In one embodiment, the extended end of the tie angle iron is provided with a tie bar and a fixing clip, the tie bar being clamped between the tie angle iron and the fixing clip.

[0020] By adopting the above scheme, when the adjacent longitudinal support members are too far apart, some brick masonry cannot distribute the load to the tie angle iron. By setting the tie steel bars, the brick masonry can distribute the load to the tie steel bars. The fixing clamp can control the fixed position of the tie steel bars, thereby controlling the extension length of the tie steel bars.

[0021] In one embodiment, the longitudinal support member has mounting seats at both ends. The mounting seats include a telescopic rod and a mounting base perpendicular to the telescopic rod. The telescopic rod is provided with a plurality of first mounting holes arranged in an array along its length direction. The first mounting holes are coaxial with the threaded holes.

[0022] By adopting the above scheme, the length of the longitudinal support can be adjusted by setting the mounting base, and the mounting plate is used to fix the longitudinal support to the ceiling or ground.

[0023] In one embodiment, the mounting base plate includes two base plates, a plurality of second mounting bolts, and a buffer plate sandwiched between the two base plates. The cross-section of the buffer plate is smaller than that of the base plates. The base plates are provided with a plurality of second mounting holes. The second mounting bolts pass through the second mounting holes of both base plates simultaneously. Each second mounting bolt is fitted with two adjusting nuts, and both adjusting nuts are located between the two base plates.

[0024] By adopting the above solution, when the mounting surface of the longitudinal support is not flat enough, the two buffer plates can be placed at a certain angle during the installation of the mounting base plate. The buffer plates deform to compensate for the tilt angle of the mounting surface. The adjusting nut limits the two base plates to prevent the angle between the two base plates from changing.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The longitudinal supports and transverse connectors directly form a frame structure. The distance between the longitudinal supports and the spacing between the transverse connectors are adjustable. The shape of the brickwork can be freely changed, avoiding material waste during the construction of the wall. The longitudinal supports and transverse connectors form an integrated frame structure. Furthermore, the longitudinal supports and transverse connectors can be prefabricated and are strong enough to support door and window openings. There is no need to use concrete to form structural columns, which simplifies the construction process of the secondary structural system wall and improves construction efficiency.

[0026] 2. When the brickwork is in rigid contact with the longitudinal support, and the brickwork expands and contracts with temperature changes, the brickwork will compress the longitudinal support, causing the column to deform and reducing its mechanical properties. The reinforcing plate is used to strengthen the structural strength of the longitudinal support. The buffer body plays a buffering role between the brickwork and the longitudinal support. Since it is difficult to keep the gap between the brickwork and the longitudinal support uniform, the middle area is difficult to be covered by the filler of the buffer body. Through the setting of the discharge chute, structural adhesive and other fillers can be injected into the longitudinal support through the threaded hole during the brickwork stacking process. Under the action of gravity, the filler flows out along the support plate and then flows between the longitudinal support and the brickwork.

[0027] 3. When the mounting surface of the longitudinal support is not flat enough, the two buffer plates can be placed at a certain angle during the installation of the mounting base plate. The buffer plates deform to compensate for the tilt angle of the mounting surface. The adjusting nut limits the two base plates to prevent the angle between the two base plates from changing.

[0033] Therefore, it is necessary to provide a secondary structural system wall construction that can effectively improve construction efficiency.

[0034] Please see Figure 1 , Figure 1 This is a structural diagram of a secondary structural system wall structure provided in this application. The secondary structural system wall structure provided in this application includes a support frame 1 and brick masonry 2, wherein the brick masonry 2 is filled in the support frame 1, and the support frame 1 plays a role in stabilizing the longitudinal support member 11, preventing the wall from collapsing, and achieving the effects of flexibly adjusting the wall size, reducing material waste, simplifying the process and improving construction efficiency.

[0035] The supporting frame 1 includes several longitudinal support members 11 and several transverse connectors 12. The transverse connectors 12 are located between two adjacent longitudinal support members 11 and are vertically fixed at any position along the length of the longitudinal support members 11. The lengths of both the longitudinal support members 11 and the transverse connectors 12 of the supporting frame 1 are adjustable, allowing for flexible size changes according to actual needs, adapting to diverse designs, avoiding material waste, and eliminating the need for concrete structural columns in the integrated frame structure, thus simplifying the process and improving efficiency. A masonry space for the brickwork 2 is formed between two adjacent transverse connectors 12 and two adjacent longitudinal support members 11.

[0036] Please refer to the following: Figure 2 , Figure 2This diagram illustrates the connection between the longitudinal support member and the mounting base. The longitudinal support member 11 is made of galvanized square steel, which possesses excellent compressive and bending resistance to ensure it can withstand significant pressure and lateral forces. It is also readily available. Each longitudinal support member 11 is arranged parallel to the others, ensuring the stability and regularity of the entire support frame 1. Mounting bases 15 are located at both ends of the longitudinal support member 11. Each mounting base 15 includes a telescopic rod 151 and a mounting plate 152 perpendicular to the telescopic rod 151. The telescopic rod 151 is typically made of metal, but can also be made of steel pipe. Multiple first mounting holes 1511 are arrayed along the length of the telescopic rod 151, and these first mounting holes 1511 are machined using a drilling process. Multiple threaded holes 111 are provided on the side of the longitudinal support member 11 along the length direction, and these threaded holes 111 are coaxial with the first mounting holes 1511. The first mounting holes 1511 on the telescopic rod 151 can be matched with different threaded holes 111 as needed, thereby adjusting the length of the longitudinal support member 11. Mounting base plate 152 is used to fix the longitudinal support 11 to the ceiling or ground, and it can evenly transfer the load of the longitudinal support 11 to the base.

[0037] In this application, the mounting base plate 152 includes two base plates 1521, a plurality of second mounting bolts 1524, and a buffer plate 1522 sandwiched between the two base plates 1521. The base plates 1521 are generally made of steel plate and have a large area and thickness to ensure sufficient load-bearing capacity. The buffer plate 1522 is typically made of elastic material such as rubber or polyurethane, and its cross-section is smaller than that of the base plates 1521. The base plates 1521 are provided with a plurality of second mounting holes 1523, and the second mounting bolts 1524 pass through the second mounting holes 1523 of both base plates 1521 simultaneously, connecting the two base plates 1521 together. Each second mounting bolt 1524 is fitted with two adjusting nuts 1525, both of which are located between the two base plates 1521. When the mounting surface of the longitudinal support 11 is not flat enough, during the installation of the mounting base plate 152, the two base plates 1521 can be placed at a certain angle, the buffer plate 1522 deforms to compensate for the tilt angle of the mounting surface, and the adjusting nut 1525 limits the two base plates 1521 to prevent the angle between the two base plates 1521 from changing, thus ensuring the stability of the installation.

[0038] The transverse connector 12 includes a sleeve 121 and a telescopic beam 122 fitted inside the sleeve 121. Both the telescopic beam 122 and the sleeve 121 can be made of galvanized square steel. The telescopic beam 122 is partially exposed in the sleeve 121. Both the sleeve 121 and the telescopic beam 122 have multiple through holes arranged in an array along their length. After adjusting the telescopic beam 122 to a suitable extension length, the through holes in the sleeve 121 and the telescopic beam 122 are aligned. Expansion bolts are then passed through the through holes in both the sleeve 121 and the telescopic beam 122 simultaneously to fix the sleeve 121 and the telescopic beam 122 at any position.

[0039] The telescopic beam 122, exposed at one end of the sleeve 121, is equipped with a fixing member 13. The fixing member 13 is generally made of metal and has high strength and stability. Its cross-section is T-shaped, including a fixing plate 131 and a mounting plate 132 perpendicular to the fixing plate 131. The fixing plate 131 is usually made of steel plate of moderate thickness bent into a U-shape, which can better fit the side of the longitudinal support member 11. The fixing plate 131 has a first mounting groove 1311 on both sides, which is a long strip-shaped groove formed by stamping or cutting. Multiple threaded holes 111 are arrayed along the length of the side of the longitudinal support member 11. The first mounting bolt 112 passes through both the first mounting groove 1311 and the threaded holes 111 to fix the fixing plate 131 to the longitudinal support member 11. The top of the fixing plate 131 can be secured with a screw that penetrates both the fixing plate 131 and the longitudinal support member 11 to further strengthen the connection between the fixing plate 131 and the longitudinal support member 11.

[0040] The transverse connector 12 is fixed to the upper surface of the mounting plate 132 by welding or bolting, thereby bearing the weight of the brickwork 2 and the transverse connector 12. The lower surface of the mounting plate 132 is provided with reinforcing ribs, thereby further enhancing the stability of the mounting plate 132. The setting of the fastener 13 ensures the connection strength and perpendicularity between the longitudinal support 11 and the transverse connector 12, making the entire support frame 1 more stable and reliable.

[0041] Please refer to the following: Figure 3 , Figure 3 yes Figure 1In the enlarged view of area A, multiple tie angle irons 14 are arranged in an array along the length of the longitudinal support member 11 facing the transverse connector 12. The tie angle irons 14 are generally made of angle steel and have an "L"-shaped cross-section. The short side of the tie angle iron 14 is fixed to the longitudinal support member 11, while the long side is sandwiched between two adjacent brick masonry blocks 2. The function of the tie angle iron 14 is to distribute the large load borne by the bottom brick masonry block 2, preventing cracks from forming due to excessive stress. A second mounting groove 143 is provided on the contact surface between the tie angle iron 14 and the discharge chute 114. The second mounting groove 143 is a slot perpendicular to the discharge chute 114, formed by milling or cutting. During installation, internal expansion bolts are simultaneously inserted into the discharge chute 114 and the second mounting groove 143 to fix the tie angle iron 14 to the longitudinal support member 11. Simultaneously, due to the presence of the second mounting groove 143, the installation position of the tie angle iron 14 can be finely adjusted to adapt to different construction needs.

[0042] The extended end of the tie angle iron 14 is provided with a tie bar 141 and a fixing clip 142. The tie bar 141 is generally made of high-strength steel and has good tensile strength. The fixing clip 142 can be in the form of a metal clip or clamp, used to clamp the tie bar 141 between the tie angle iron 14 and the fixing clip 142. When the adjacent longitudinal support members 11 are too far apart, part of the brick masonry 2 cannot distribute the load to the tie angle iron 14. At this time, the tie bar 141 can play a role. The brick masonry 2 distributes the load to the tie bar 141, and the fixing clip 142 can control the fixed position of the tie bar 141, thereby controlling the extension length of the tie bar 141 and further enhancing the stability of the wall.

[0043] Please refer to the following: Figure 4 , Figure 4 This is a cross-sectional view of the connection between the longitudinal support member and the mounting base. The longitudinal support member 11 contains a reinforcing plate 113, typically made of high-strength steel plate, including a partition plate 1131 and support plates 1132 welded to both sides of the partition plate 1131. The partition plate 1131 extends along the length of the longitudinal support member 11 and is generally formed into a specific shape by bending the steel plate. Its thickness and width are designed according to the dimensions and load-bearing requirements of the longitudinal support member 11. The end of the support plate 1132 facing away from the partition plate 1131 is fixed to the inner wall of the longitudinal support member 11 by welding, thus strengthening the structural strength of the longitudinal support member 11. When the brickwork 2 is in rigid contact with the longitudinal support member 11, the thermal expansion and contraction of the brickwork 2 due to factors such as changes in ambient temperature will compress the longitudinal support member 11. Without the reinforcing plate 113, the longitudinal support member 11 is prone to deformation, reducing its mechanical properties. The reinforcement plate 113 can effectively disperse the pressure, improve the deformation resistance of the longitudinal support 11, and ensure the stability of the entire wall structure.

[0044] The longitudinal support member 11 has a discharge trough 114 on its side facing the transverse connector 12. The discharge trough 114 is an elongated slot opened on the side of the longitudinal support member 11. The support plate 1132 is inclined downward and its plane is in contact with the lower side of the discharge trough 114. During the stacking of the brick masonry 2, structural adhesive and other fillers can be injected into the longitudinal support member 11 through the threaded hole 111. Under the action of gravity, the filler flows out along the support plate 1132 and then flows between the longitudinal support member 11 and the brick masonry 2, filling the gap between the two and enhancing the integrity and sealing of the wall. In addition to filling with filler, asphalt-impregnated hemp fibers can also be added to the gap between the longitudinal support member 11 and the brick masonry 2. The asphalt-impregnated hemp fibers are mixed with structural sealant to form a buffer body 3, which has good buffering performance and can absorb the stress generated by the thermal expansion and contraction of the brick masonry 2, reducing the compression on the longitudinal support member 11.

[0045] During installation, first, measurements are taken to mark the positions of the walls, door openings, and control lines, as well as the positions of the door frame posts. The posts are then installed, ensuring they are vertical. The second mounting bolt 1524 is passed through the second mounting hole 1523 and fixed to the ceiling or ground. Next, measurements are taken to mark the lines, including the top of the door, the window, and other openings. The fixing member 13 is then moved to a suitable height, and the first mounting groove 1311 and threaded hole 111 are fixed using the first mounting bolt 112, thereby fixing the longitudinal support member 11 and the fixing member 13. The telescopic beams 122 at both ends of the transverse connecting member 12 are bolted or welded to the mounting plate 132. The length of the transverse connecting member 12 is adjusted using the sleeve 121.

[0046] Next, the connection between the longitudinal support 11 and the transverse connector 12 is welded to ensure the stability of the structure between the longitudinal support 11 and the beam. Then, brick masonry 2 is constructed. During the construction of brick masonry 2, tie angle irons 14 are installed according to the spacing requirements. If the wall length exceeds 2m, tie steel bars 141 are required. The tie steel bars 141 and tie angle irons 14 are lapped and fixed using fixing clips 142 or welded together. The length of a single-sided weld is not less than 10d, and the length of a double-sided weld is not less than 5d. After the masonry structure system is accepted, silicate cover plates are installed and fixed on the galvanized longitudinal support 11 and the beam surface using self-tapping screws arranged in a staggered pattern with a vertical spacing of 10cm and a horizontal spacing of 5cm. Filler is used to fill the gap between the longitudinal support 11 and the brick masonry 2 to form a buffer body 3. All structures of the support frame 1 can be customized and mass-produced, simplifying the process flow of the secondary structure system and improving work efficiency.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
