Description

Technical Field

[0001] The present invention relates to the technical field of building node connections, and particularly to a connection node between a steel reinforced concrete column and a prestressed reinforced concrete beam. Background Art

[0002] The connection node between a steel reinforced concrete column and a prestressed reinforced concrete beam refers to a key structural part for transferring loads and coordinating deformations in a structure; this node combines two different materials (steel + concrete) and components with different mechanical properties (the elasticity of the prestressed beam and the plasticity of the steel reinforced concrete column), and needs to meet requirements such as strength, stiffness, ductility, and construction feasibility to ensure the overall safety, stability, and durability of the structure.

[0003] There are various connection methods between a steel reinforced concrete column and a prestressed reinforced concrete beam. Taking the method of adding a steel corbel for connection as an example, in the actual construction process of this type of connection node, there are the following problems: on the one hand, after the traditional steel reinforced concrete column and prestressed reinforced concrete beam are connected and welded in the general framework, it is necessary to carry out bending and cutting operations on the redundant steel bars at the tail of the longitudinal bars of the middle beam, and then use a multi-bundle tying bar structure to bind the overall longitudinal bars of the framework. This not only leads to surplus consumption of materials, but also the strength of the node structure without concrete filling is limited by the tying bars, and the structural strength needs to be improved; on the other hand, during the construction process, when welding the steel corbel, the connecting plate, and the steel section in the column, the positions of the steel corbel and the connecting plate are determined subjectively by the workers, which requires certain technical skills for the welders themselves and there are construction shortcomings. Summary of the Invention

[0004] The present invention discloses a connection node between a steel reinforced concrete column and a prestressed reinforced concrete beam, aiming to solve the technical problems that there are certain construction shortcomings and limitations in the existing connection node between a steel reinforced concrete column and a prestressed reinforced concrete beam during actual operation.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A connection node between a steel reinforced concrete column and a prestressed reinforced concrete beam, including a steel section in the column erected on the ground, a connection component is installed in the middle of the steel section in the column, the connection component includes two groups of connecting plates that slide into both sides of the steel section in the column through the ends of the steel section in the column, and a bolt rod is threadedly connected between the two connecting plates distributed vertically. A number of steel corbels are attached to the outside of the steel section in the column;

[0007] A beam frame component is provided on the outside of the steel section in the column;

[0008] A fixing component is arranged on the outer side of the connecting component. The fixing component is fixed on the outer side of the internal steel shape of the column. The fixing component includes several middle beam longitudinal reinforcements penetrating out from the side of the internal steel shape of the column. A section of length is reserved at the end of the middle beam longitudinal reinforcement and is bent and anchored along the outer side of the steel corbel to form a bundled reinforcement part.

[0009] By arranging a connecting component in the middle of the internal steel shape of the column, the internal steel shape of the column and the beam frame component are connected by the connecting component to complete the preliminary connection of the steel reinforced concrete column and the prestressed reinforced concrete beam. At the same time, the additionally arranged fixing component can use the materials of the beam frame component itself to replace the bundled reinforcement structure, saving the tediousness of a large amount of bundled reinforcement required in traditional joint connections. Thus, while improving the structural strength of the connection node between the steel reinforced concrete column and the prestressed reinforced concrete beam, the construction convenience is improved.

[0010] In a preferred solution, positioning members are arranged at the ends of each connection plate of the connecting component. The distance between the connection plates is adjusted by the bolt rod, causing the positioning members to be in pressing contact with the inner side of the steel corbel. Then, the connection plate and the steel corbel are fixed to the outer side of the internal steel shape of the column by welding.

[0011] By arranging each group of connection plates to be connected by a bolt rod and using the rotation of the bolt rod to adjust the distance between the two connection plates, and cooperating with the positioning member structures additionally arranged on both sides of the connection plate, when the worker initially installs the steel corbel, the relative movement of the positioning member is driven by the connection plate to form a clamping force on the inner side of the steel corbel, thereby assisting the worker in positioning the steel corbel and the connection plate, causing the steel corbel and the connection plate to be on the same horizontal line and facilitating subsequent welding by the worker.

[0012] In a preferred solution, the beam frame component includes several through longitudinal reinforcements evenly distributed on the outer side of the internal steel shape of the column. Several symmetrically distributed beam middle longitudinal reinforcements are welded and fixed to the upper and lower ends of each steel corbel. A group of symmetrically distributed sleeves are welded and fixed to the upper and lower ends of each steel corbel. A longitudinal structural reinforcement is inserted into the interior of each sleeve, and the sleeve and the longitudinal structural reinforcement are fixed by welding. Two groups of beam edge longitudinal reinforcements are symmetrically distributed on the side of the internal steel shape of the column. Each group of beam edge longitudinal reinforcements consists of two. One group of the beam edge longitudinal reinforcements penetrates out from the interior of the internal steel shape of the column, and the other group of the beam edge longitudinal reinforcements passes through between the through longitudinal reinforcement and the internal steel shape of the column and is bent towards the direction of the internal steel shape of the column under the influence of the through longitudinal reinforcement.

[0013] By using the internal steel shape of the column as the base column, through longitudinal reinforcements, beam middle longitudinal reinforcements, longitudinal structural reinforcements, and beam edge longitudinal reinforcements are arranged. Different types of steel bars are welded in cooperation with the steel corbel structure to form the basic framework of the steel reinforced concrete column and the prestressed reinforced concrete beam, maintaining the stability after subsequent concrete filling.

[0014] In a preferred embodiment, the fixing component further includes a plurality of through openings formed on the outer side of the steel bracket, the tying bar portion is engaged with the inside of the through openings, a tying bar member is distributed in the middle of the plurality of tying bar portions, and the tying bar member is also engaged with the inside of the through openings. A plurality of sets of buckles are symmetrically clamped at the corners of the plurality of tying bar portions and the tying bar member. While the plurality of buckles are clamped on the outer sides of the tying bar portions and the tying bar member, they are in pressing contact with the adjacent penetrating longitudinal bars, thereby forming a fixing structure.

[0015] By additionally providing a through opening structure on the outer side of the steel bracket, after the end of the middle beam longitudinal bar penetrates from the side of the steel section in the column, a length is reserved at the end of the middle beam longitudinal bar and it is bent and anchored along the outer side of the steel bracket to form a tying bar portion, which restricts a plurality of penetrating longitudinal bars distributed outside the steel section in the column. With the mutual engagement of a single tying bar member and a plurality of buckles, the structural strength of this connection node is greatly improved.

[0016] In a preferred embodiment, a convex point is additionally provided at the through opening on one of the steel brackets, and the convex point is engaged with the outer sides of the tying bar portion and the tying bar member.

[0017] By providing a convex point at the through opening on one of the steel brackets, when the buckle clamps and fixes the tying bar portion, the extrusion of the buckle is used to drive a small lift of the tying bar portion and the tying bar member, so as to form an extrusion with the convex point inside the through opening, thereby further improving the stability of this connection node.

[0018] As can be seen from the above, a connection node between a steel reinforced concrete column and a prestressed reinforced concrete beam provided by the present invention has the following technical effects.

[0019] Firstly: By setting each group of connection plates to be connected by bolt rods and using the rotation of the bolt rods to adjust the distance between the two connection plates, in cooperation with the positioning member structures additionally provided on both sides of the connection plates, when the worker initially installs the steel bracket, the positioning members are used to assist the worker in positioning the steel bracket, so that the steel bracket and the connection plate are on the same horizontal line, which is convenient for the worker to perform subsequent welding and ensures the accuracy of the position after the steel bracket and the connection plate are welded.

[0020] Second: By taking the steel shape in the column as the base column, with through longitudinal bars, longitudinal bars in the beam, longitudinal structural bars, and longitudinal bars at the beam edge provided, and using different types of steel bars to cooperate with the steel bracket structure for welding, a basic framework of a steel reinforced concrete column and a prestressed reinforced concrete beam is formed. At the same time, a through-hole structure is additionally provided on the outer side of the steel bracket. After the end of the longitudinal bar in the beam penetrates from the side of the steel shape in the column, a certain length is reserved at the end of the longitudinal bar in the beam and bent and anchored along the outer side of the steel bracket to form a bundled bar part, which binds several through longitudinal bars distributed on the outer side of the steel shape in the column. With the mutual engagement of a single bundled bar piece and several buckles, the structural strength and stability of this connection node are greatly improved. Different from the fixing method of traditional connection nodes, this node can save bundled bars while making use of the surplus materials. Moreover, since the bundled bar part formed by the reserved part at the end of the longitudinal bar in the beam is different from the traditional bundled bar, its structural strength is greater.

[0021] Third: A convex point is additionally provided at the through-hole on one of the steel brackets. When the buckle engages and fixes the bundled bar part, the extrusion of the buckle is used to drive a small lift of the bundled bar part and the bundled bar piece, so that the bundled bar part and the bundled bar piece form extrusion with the convex point inside the through-hole, and then detailed processing is carried out to further improve the stability and structural strength of this connection node.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] A connection node between a profiled steel concrete column and a prestressed reinforced concrete beam disclosed by the present invention is mainly applied to the scenario of connecting a profiled steel concrete column and a prestressed reinforced concrete beam.

[0034] Refer to Figures 1 to 9 , a connection node between a profiled steel concrete column and a prestressed reinforced concrete beam, including the profiled steel 1 inside the column erected on the ground. A connection component 2 is installed in the middle of the profiled steel 1 inside the column. The connection component 2 includes two groups of connecting plates 201 that slide into both sides of the profiled steel 1 inside the column through the end of the profiled steel 1 inside the column. A bolt rod 202 is threadedly connected between the two connecting plates 201 distributed vertically. A number of steel corbels 203 are attached to the outside of the profiled steel 1 inside the column;

[0035] A beam frame component 3 is arranged on the outside of the profiled steel 1 inside the column;

[0036] A fixing component 4 is arranged on the outside of the connection component 2. The fixing component 4 is fixed to the outside of the profiled steel 1 inside the column. The fixing component 4 includes several middle beam longitudinal reinforcements 401 that penetrate out from the side of the profiled steel 1 inside the column. A section of length is reserved at the end of the middle beam longitudinal reinforcement 401 and it is bent and anchored along the outside of the steel corbel 203 to form a bundled reinforcement part 403, and it is bundled and fixed with the beam frame component 3, and the steel corbel 203 provides an outward expansion limiting force for the bundled reinforcement part 403.

[0037] In this embodiment: The profiled steel inside the column 1 is fixed on the plane by concrete pouring. At the same time, the worker holds the connecting component 2 and snaps the connecting plate 201 into the column profiled steel 1 from the upper end downwards. When snapping in, the outer right-angled side of the connecting plate 201 will fit with the inner right-angled side outside the column profiled steel 1 and slide down along the outside of the column profiled steel 1. After sliding the connecting component 2 to the specified position, the worker then uses welding equipment to fix the connecting component 2 to the column profiled steel 1. After that, the worker successively fixes the beam frame component 3 on the outside of the column profiled steel 1 according to the preset points, and then fixes the beam frame component 3 through the fixing component 4 to complete the installation of the internal frame of the profiled steel concrete column and the prestressed reinforced concrete beam. After that, the worker seals the outside of the entire frame with a cover plate, then pours concrete slurry into the inside of the frame and waits for the concrete slurry to solidify to complete the construction of the connecting structure of the profiled steel concrete column and the prestressed reinforced concrete beam.

[0038] Refer to Figures 3 to 4 、 Figures 6 to 7 , in a preferred embodiment, the connecting component 2 further includes a positioning member 204 provided at the end of each connecting plate 201. The distance between the connecting plates 201 is adjusted by the bolt rod 202, causing the positioning member 204 to squeeze and contact the inner side of the steel bracket 203, and then the connecting plate 201 and the steel bracket 203 are fixed to the outside of the column profiled steel 1 by welding.

[0039] Specifically, the worker holds the connecting plate 201 and snaps the connecting plate 201 into the column profiled steel 1 from the upper end downwards. When snapping in, the outer right-angled side of the connecting plate 201 will fit with the inner right-angled side outside the column profiled steel 1 and slide down along the outside of the column profiled steel 1. After sliding the connecting plate 201 to the specified position, the bolt rod 202 is rotated, causing the two connecting plates 201 to move relatively outwards. At the same time, another worker fits the steel bracket 203 to the preset point on the outside of the column profiled steel 1. As the two connecting plates 201 move, the positioning members 204 at the ends of the connecting plates 201 will gradually squeeze the two sides of the steel bracket 203, thus completing the positioning and preliminary connection of the steel bracket 203 and the connecting plate 201. At this time, the worker can weld the entire connecting plate 201 and the steel bracket 203 to the column profiled steel 1 with the help of welding equipment; among them, the outer side of the bolt rod 202 is threadedly connected with a nut 205, and the nut 205 squeezes and contacts the outside of the connecting plate 201, and the relative distance between the two connecting plates 201 is controlled by rotating the nut 205.

[0040] Refer to Figures 1 to 6, in a preferred embodiment, the beam frame assembly 3 includes a plurality of through longitudinal bars 301 evenly distributed outside the internal steel section 1 of the column. At both the upper and lower ends of each steel bracket 203, a plurality of symmetrically distributed longitudinal bars 303 in the beam are welded and fixed. At both the upper and lower ends of each steel bracket 203, a set of symmetrically distributed sleeves 304 are welded and fixed. Inside each sleeve 304, a longitudinal structural bar 305 is inserted, and the sleeve 304 and the longitudinal structural bar 305 are fixed by welding. On the side of the internal steel section 1 of the column, two groups of longitudinal bars 306 at the beam edge are symmetrically distributed. Each group of longitudinal bars 306 at the beam edge consists of two bars. One group of longitudinal bars 306 penetrates out from the inside of the internal steel section 1 of the column, and the other group of longitudinal bars 306 passes through the space between the through longitudinal bars 301 and the internal steel section 1 of the column and bends towards the internal steel section 1 of the column under the influence of the through longitudinal bars 301.

[0041] When pouring and fixing the internal steel section 1 of the column, it is necessary to pour and fix a plurality of through longitudinal bars 301 at the same time. After the steel brackets 203 are fixed, at this time, the workers symmetrically weld a plurality of longitudinal bars 303 in the beam in pairs to the upper and lower ends of the steel brackets 203 according to the preset positions on the drawing. At the same time, the longitudinal structural bars 305 are inserted into the inside of the sleeves 304 and then welded and fixed. Two longitudinal bars 306 at the beam edge of one group are passed through the inside of the internal steel section 1 of the column and then welded, while the two longitudinal bars 306 at the beam edge of the other group pass through the space between a plurality of through longitudinal bars 301 and the internal steel section 1 of the column and then fixed; among them, a plurality of groups of embedded grooves 302 are provided at the ends of the steel brackets 203, and the ends of the longitudinal bars 303 in the beam are embedded into the inside of the embedded grooves 302 and then fixed by welding. Inside the internal steel section 1 of the column, a plurality of circular holes 101 are penetrated, and the longitudinal bars 306 at the beam edge and the longitudinal bars 401 in the middle beam penetrate through the circular holes 101 in sequence.

[0042] Refer to Figures 1 to 4 , Figures 6 to 8 , in a preferred embodiment, the fixing assembly 4 further includes a plurality of through openings 402 opened on the outside of the steel brackets 203. The bundling part 403 is clamped inside the through openings 402. In the middle of a plurality of bundling parts 403, a bundling member 404 is distributed. The bundling member 404 is clamped into the inside of the through openings 402 together. At the folding corners of a plurality of bundling parts 403 and the bundling member 404, a plurality of groups of buckles 405 are symmetrically clamped. While a plurality of buckles 405 are clamped on the outside of the bundling parts 403 and the bundling member 404, they are in pressing contact with the adjacent through longitudinal bars 301, thereby forming a fixing structure.

[0043] Workers pass several longitudinal bars 401 of the middle beam through from one side of the steel section 1 inside the column. At the same time, a certain length is reserved at the end of the longitudinal bars 401 of the middle beam. After the longitudinal bars 401 of the middle beam pass through, at this time, the workers use a handheld bending machine to bend the end of the longitudinal bars 401 of the middle beam into a "mouth" - shaped structure, thereby forming a bundling part 403. And during the process of bending and forming the bundling part 403, the bundling part 403 needs to be successively clamped into the through - holes 402 outside several steel corbels 203. After that, the worker additionally holds a bundling piece 404 and clamps the bundling piece 404 into the through - holes 402 in the middle of each row. Then, holding several buckles 405, the buckles 405 are successively clamped outside the bundling part 403 and the bundling piece 404. The buckles 405 are in the shape of ox horns. Press the two ends of the buckle 405 with both thumbs of the hands to make it bend and deform to the rear of the through - longitudinal bar 301. After releasing the hands, the reset buckle 405 can exert a binding force on the through - longitudinal bar 301, the bundling part 403 and the bundling piece 404, improving the stability among them, thus forming a fixed structure; among them, because the end of the longitudinal bar 401 of the middle beam is bent into a "mouth" - shaped structure, and the end of the bundling part 403 is fixed to the through - longitudinal bar 301 by tying a knot with a wire 406; and a break - opening 4041 is opened at the end of the bundling piece 404. The bundling piece 404 is bent through the break - opening 4041 and is reset and clamped outside the steel corbel 203 through elastic deformation.

[0044] Furthermore, as Figure 4 shown, a convex point 4021 is additionally provided at the through - hole 402 of one of the steel corbels 203 on the left side. When the worker clamps the buckle 405 outside the bundling part 403 and the bundling piece 404, the sides of the bundling part 403 and the bundling piece 404 will be squeezed by the buckle 405 to generate an upward component force, causing the bundling part 403 and the bundling piece 404 to have an upward displacement. At this time, the convex point 4021 will be clamped outside the bundling part 403 and the bundling piece 404, thereby forming a restriction to prevent the bundling part 403 and the bundling piece 404 from expanding outwards and detaching.

[0045] Specific construction process: During use, the steel section 1 inside the column and several through - longitudinal bars 301 are poured and fixed on the plane according to the set points. The worker holds the connecting plate 201 and inserts the connecting plate 201 downward from the upper end of the steel section 1 inside the column. When inserting, the outer right - angled edge of the connecting plate 201 will fit with the inner right - angled edge outside the steel section 1 inside the column and slide downward along the outside of the steel section 1 inside the column. After sliding the connecting plate 201 to the designated position, rotate the bolt rod 202, causing the two connecting plates 201 to move relatively outward. At the same time, another worker fits the steel corbel 203 to the preset position outside the steel section 1 inside the column. As the two connecting plates 201 move relatively outward, the positioning members 204 at the ends of the connecting plates 201 will gradually press on both sides of the steel corbel 203 (as Figure 4as shown in the figure), thus completing the positioning and preliminary connection of the steel bracket 203 and the connecting plate 201. At this time, the worker uses welding equipment to weld the entire connecting plate 201 and the steel bracket 203 to the internal steel section 1 of the column;

[0046] After the fixation of the steel bracket 203 is completed, at this time, the worker symmetrically welds several longitudinal beam bars 303 in pairs to the upper and lower ends of the steel bracket 203 according to the preset points on the drawing (as Figure 6 shown). At the same time, the longitudinal structural steel bars 305 are inserted into the inside of the sleeve 304 and then welded and fixed. Two beam edge longitudinal bars 306 of one group are passed through the inside of the internal steel section 1 of the column and then welded, while the two beam edge longitudinal bars 306 of the other group are passed through and fixed between several through longitudinal bars 301 and the internal steel section 1 of the column (as Figure 5 shown). After the arrangement of the steel reinforced concrete column and the prestressed reinforced concrete beam foundation frame is completed, the worker then passes several middle beam longitudinal bars 401 out from one side of the internal steel section 1 of the column. At the same time, a section of length is reserved at the end of the middle beam longitudinal bar 401. After the middle beam longitudinal bar 401 passes through, at this time, the worker uses a handheld bending machine to bend the end of the middle beam longitudinal bar 401 into a "mouth" - shaped structure, thus forming a bundling part 403 (as Figure 8 shown). And during the process of bending and forming the bundling part 403, the bundling part 403 needs to be successively clamped into the through - holes 402 on the outside of several steel brackets 203. After that, the worker additionally holds a bundling part 404 and clamps the bundling part 404 into the through - holes 402 in the middle of each row. Then, the worker holds several buckles 405. The buckles 405 are in the shape of a horn. Press the two ends of the buckle 405 with both thumbs of the hands to make it bend and deform to the rear of the through longitudinal bar 301. After releasing the hands, the reset buckle 405 can exert a binding force on the through longitudinal bar 301, the bundling part 403 and the bundling part 404, improving the mutual stability (as Figure 1 and Figure 7 shown). Since the end of the middle beam longitudinal bar 401 is bent into a "mouth" - shaped structure, and the end of the bundling part 403 is fixed to the through longitudinal bar 301 by tying a knot with a wire 406, a fixed structure is formed. The specific process is as shown in the appendix Figure 9 shown; After that, the worker seals the outside of the entire frame with a cover plate, then pours concrete slurry into the inside of the frame, and waits for the concrete slurry to solidify, completing the construction of the connection structure between the steel reinforced concrete column and the prestressed reinforced concrete beam.

[0047] The above - mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
