Description

Technical Field

[0001] This invention relates to the technical field of prefabricated hybrid wall structure systems, and in particular to a prefabricated edge-type steel column-composite wall structure system. Background Technology

[0002] High-rise building structures are a solution to the growing urban population and the increasing scarcity of urban land in my country's urbanization process. Prefabricated buildings are an inevitable choice for future green and low-carbon construction methods. Although prefabricated steel structures have advantages such as high standardization and high construction efficiency, their fire resistance, sound insulation, and thermal insulation performance are somewhat insufficient. Therefore, prefabricated concrete structure systems remain the majority choice at present. However, existing prefabricated shear wall structures mostly use prefabricated reinforced concrete walls, resulting in heavy single-panel hoisting weights and a risk of leakage at floor joints.

[0003] Prefabricated hybrid coupled wall structures utilize steel components for concealed columns, connecting beams, and joints, while other parts are constructed with reinforced concrete. Using steel components for horizontal and vertical connections allows for rapid assembly of the structural frame, improving construction efficiency. Simultaneously, changing the form of the steel components effectively enhances the standardization of precast concrete components. Steel-concrete structures offer advantages such as good sound insulation, thermal insulation, fire resistance, and good local and overall structural stability. However, in existing hybrid coupled wall structures, the reinforced concrete walls are often prefabricated as a whole, resulting in heavy overall weight. Furthermore, connecting upper and lower walls requires lateral support and on-site reinforcement binding, hindering rapid assembly into a unified structure.

[0004] Prefabricated double-sided composite wall structure system has advantages such as light weight of single prefabricated wall panels and less risk of leakage at joints. However, the longitudinal steel bars of the wall at the horizontal joints of the floors cannot be directly connected, and lateral support is required when connecting the upper and lower walls. This can easily form a weak seismic zone, and the shear wall confinement end columns need to be tied separately on site.

[0005] Although a Chinese invention patent application with publication date of April 6, 2021, and application publication number CN 112609869 A discloses a prefabricated double-sided composite shear wall with concealed steel sections, including two leaf plates connected by steel sections with H-shaped cross-sections, the four ends of the H-shape connecting to the reinforcing bars in the leaf plates, and the steel sections arranged longitudinally within the leaf plates and protruding from the top and bottom ends of the leaf plates, thus improving construction efficiency to some extent, the steel sections in the aforementioned patent are only used to replace vertical reinforcing bars, serving only to transfer internal stress within the inter-story wall and not to improve the overall seismic performance of the structure. Furthermore, the H-shaped steel sections used in the aforementioned patent have weak bending resistance along the direction perpendicular to the wall, making them unsuitable as edge restraint components. Secondly, the reinforcing bars in the aforementioned patent do not protrude from the wall, and the horizontal joints are mainly borne by the steel sections at the inter-story joints, which easily leads to stress concentration in the steel sections. The overall synergy between the steel sections and the concrete wall is poor, and because the spacing between the steel sections is larger than that of the reinforcing bars, the concrete wall's crack resistance is poor. In addition, the steel sections in the above-mentioned patents are connected by welding, bolts or flanges. This connection method has low construction efficiency and requires auxiliary construction such as lateral support. Summary of the Invention

[0006] To address the shortcomings in the aforementioned background technology, this invention proposes a prefabricated edge-type steel column-composite wall structure system, which solves the technical problems of weak seismic performance at the connection between the upper and lower layers of existing double-layer hollow composite walls, low construction efficiency, and long construction period.

[0007] The technical solution of this application is as follows:

[0008] A prefabricated edge-type steel column-composite wall structure system includes several edge-type steel column-composite wall structure units connected sequentially in the vertical and horizontal directions. Each edge-type steel column-composite wall structure unit includes a double-leaf hollow composite wall. Vertically arranged steel columns are provided at the edges of the left and right sides of the double-leaf hollow composite wall. The upper and lower ends of the steel columns extend out of the double-leaf hollow composite wall, and the outer sides are connected to joint steel beams that extend laterally to the outside of the double-leaf hollow composite wall. The upper and lower adjacent edge-type steel column-composite wall structure units are fixed by inserting the steel columns, and the left and right adjacent edge-type steel column-composite wall structure units are connected by the joint steel beams.

[0009] Furthermore, the steel column includes two embedded steel plates pre-embedded in the two wall bodies of the double-sided cavity composite wall, and the two embedded steel plates are connected by a connecting steel plate located in the cavity of the double-sided cavity composite wall. The joint steel beam is connected to the steel column through the connecting steel plate.

[0010] Furthermore, a reinforcing steel plate is connected to the middle position of the connecting steel plate, and the joint steel beam is connected to the steel column through the reinforcing steel plate.

[0011] Furthermore, both the connecting steel plate and the reinforcing steel plate are provided with several holes. A stop steel plate is connected to the outside of the connecting steel plate. The two sides of the stop steel plate are respectively embedded in the two walls of the double-leaf cavity composite wall. The joint steel beam is connected to the steel column through the reinforcing steel plate.

[0012] Furthermore, the embedded steel plate is arranged parallel to the wall of the double-leaf cavity composite wall, the connecting steel plate is perpendicular to the embedded steel plate, the reinforcing steel plate is perpendicular to the connecting steel plate, the stop steel plate is perpendicular to the reinforcing steel plate, and the joint steel beam is perpendicular to the stop steel plate.

[0013] Furthermore, a tensioning steel bar is provided on the side of the reinforcing steel plate away from the stop steel plate, and the width of the tensioning steel bar is greater than the thickness of the reinforcing steel plate.

[0014] Furthermore, the height of the embedded steel plate and the connecting steel plate at the upper end of the steel column are both lower than the height of the reinforcing steel plate and the stop steel plate, while the height of the embedded steel plate and the connecting steel plate at the lower end of the steel column are both higher than the height of the reinforcing steel plate and the stop steel plate.

[0015] Furthermore, the vertical reinforcing bars on the double-leaf cavity composite wall extend from the upper and lower ends of the wall, and the vertical reinforcing bars between adjacent double-leaf cavity composite walls are lapped together.

[0016] Furthermore, the lap length of the vertical reinforcing bars is less than the length of the steel column extending out of the double-layer cavity composite wall, and the vertical reinforcing bars are staggered by one reinforcing bar diameter when horizontally arranged in the edge steel column-composite wall structural unit at odd and even positions.

[0017] Furthermore, the horizontal gap formed between adjacent edge-type steel column-composite wall structural units is higher than the horizontal height of the floor slab.

[0018] Compared with the prior art, the technical solution of the present invention has the following technical effects:

[0019] 1. This invention uses cross-shaped steel columns as edge restraint members, which is beneficial for improving the seismic performance of the wall and the overall structure; the use of steel columns to connect the upper and lower shear walls facilitates on-site construction and ensures reliable connections. This allows for direct connection of the vertical reinforcing bars of the upper and lower walls, improving the seismic performance at the connection point of the upper and lower double-layer hollow composite walls.

[0020] 2. In this invention, the vertical reinforcing bars of the wall extend out of the wall, and the inter-layer connection adopts lap connection, which is equivalent to the cast-in-place structure. At the same time, the steel columns are used as shear wall constraint end columns, avoiding the need for on-site binding of reinforcing bars for shear wall constraint end columns, thus improving construction efficiency.

[0021] 3. The steel sections in this invention employ a plug-in connection, which is simple to use. No lateral support is required for connecting upper and lower walls, enabling rapid formation of the structural framework, greatly improving assembly efficiency, effectively saving project time, and facilitating the promotion and application of prefabricated buildings. Using steel columns as connecting components during installation avoids the need for lateral support in prefabricated shear walls, improving construction convenience. Furthermore, combined with pre-embedded joint steel beams, the prefabricated walls can quickly form an overall frame, greatly improving installation efficiency.

[0022] 4. Using cross-shaped steel columns to connect the inner and outer leaves of the double-leaf hollow composite wall reduces the number of truss reinforcements inside the double-leaf hollow composite wall, facilitates concrete pouring and vibration inside the cavity, and helps ensure the quality of concrete molding.

[0023] 5. By combining steel components such as steel connecting beams and steel columns, multiple combinations of double-leaf hollow composite walls can be achieved, improving the standardization of double-leaf hollow composite walls, reducing costs, and helping to promote the market-oriented operation of prefabricated buildings.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention relates to the field of building construction technology, and in particular to a prefabricated edge-type steel column-composite wall structure system, which solves the technical problem that the steel bars are not connected at the connection between upper and lower floors of existing prefabricated double-sided composite walls, forming a weak zone in shear resistance; it does not contain end-restrained edge columns, and the steel bars of the restrained edge columns need to be tied separately on site, which is inconvenient for construction; and it also solves the problem that the installation efficiency is low due to reliance on lateral supports during the installation of composite shear walls.

[0038] The prefabricated edge-type steel column-composite wall structure system includes multiple composite wall units connected horizontally and vertically, composite floor slabs connecting two adjacent coupled wall units, and steel connecting beams. Each composite wall unit consists of a composite wall body, cross-shaped steel columns, and joint steel beams. In the composite wall body, the cross-shaped steel columns have vertical reinforcement extending a certain length from the wall body on both the upper and lower sides. The upper-layer cross-shaped steel columns and the lower-layer pre-reserved cross-shaped steel columns are initially connected by a plug-in joint, and then welded and tightened after correction.

[0039] A prefabricated edge-type steel column-composite wall structure system, such as Figure 1 As shown, the structure includes several edge-type steel column-composite wall structural units 1 connected sequentially in the vertical and horizontal directions. Each edge-type steel column-composite wall structural unit 1 includes a double-leaf hollow composite wall 2. Vertically arranged steel columns 3 are provided at the edges of the left and right sides of the double-leaf hollow composite wall 2. The upper and lower ends of the steel columns 3 extend out of the double-leaf hollow composite wall 2 and are connected to the outer side by joint steel beams 4 that extend laterally outward from the double-leaf hollow composite wall 2. The upper and lower adjacent edge-type steel column-composite wall structural units 1 are fixed together by inserting the steel columns 3, and the left and right adjacent edge-type steel column-composite wall structural units 1 are connected by the joint steel beams 4.

[0040] Specifically, a portion of the steel column 3 is pre-embedded within the concrete wall panels on both sides of the double-leaf hollow composite wall 2, while the other portion is located within the cavity enclosed by the concrete wall panels on both sides of the double-leaf hollow composite wall 2. That is, while connecting the concrete wall panels on both sides of the double-leaf hollow composite wall 2, the steel column 3 also provides support and sealing for the pouring and vibration of the double-leaf hollow composite wall 2. Simultaneously, the steel column 3 can also be used to temporarily fix adjacent edge steel column-composite wall structural units 1, which can be directly plugged in after hoisting, eliminating the need for lateral supports.

[0041] Alternatively, reinforcement can be achieved through welding after insertion; of course, welding reinforcement can also be omitted. The joint steel beam 4 connected to the steel column 3 is used for the horizontal connection of the edge steel column-composite wall structural unit 1. That is, after assembly construction, the vertical and horizontal nodes are integral structures, and the seismic performance, assembly efficiency, and forming quality of the coupled assembly structural system are further improved.

[0042] Preferably, the steel column 3 is a cross-shaped steel column, and slender studs are arranged on the flange of the steel column 3.

[0043] Based on the above embodiments, as a preferred embodiment, such as... Figure 2 As shown, the steel column 3 includes two embedded steel plates 301 that are respectively embedded in the two walls of the double-sided cavity composite wall 2. The two embedded steel plates 301 are connected by a connecting steel plate 302 located in the cavity of the double-sided cavity composite wall 2. The joint steel beam 4 is connected to the steel column 3 through the connecting steel plate 302.

[0044] Based on the above embodiments, as a preferred embodiment, such as... Figure 2 , Figure 4 , Figure 5 As shown, a reinforcing steel plate 303 is connected to the middle position of the connecting steel plate 302, and the joint steel beam 4 is connected to the steel column 3 through the reinforcing steel plate 303.

[0045] Based on the above embodiments, as a preferred embodiment, both the connecting steel plate 302 and the reinforcing steel plate 303 are provided with several holes to facilitate concrete pouring and vibration, and to improve the molding quality. A stop steel plate 304 is connected to the outer side of the connecting steel plate 302, and the two sides of the stop steel plate 304 are respectively embedded in the two walls of the double-layer hollow composite wall 2. The joint steel beam 4 is connected to the steel column 3 through the reinforcing steel plate 303.

[0046] Based on the above embodiments, as a preferred embodiment, the embedded steel plate 301 is arranged parallel to the wall of the double-leaf cavity composite wall 2, the connecting steel plate 302 is perpendicular to the embedded steel plate 301, the reinforcing steel plate 303 is perpendicular to the connecting steel plate 302, the stop steel plate 304 is perpendicular to the reinforcing steel plate 303, and the joint steel beam 4 is perpendicular to the stop steel plate 304.

[0047] Based on the above embodiments, as a preferred embodiment, a tensioning steel bar 305 is provided on the side of the reinforcing steel plate 303 away from the stop steel plate 304. The width of the tensioning steel bar 305 is greater than the thickness of the reinforcing steel plate 303, so that a reliable tensioning effect can be formed after the concrete is poured.

[0048] Based on the above embodiments, as a preferred embodiment, such as... Figures 3-5 As shown, the height of the embedded steel plate 301 and the height of the connecting steel plate 302 at the upper end of the steel column 3 are both lower than the height of the reinforcing steel plate 303 and the height of the blocking steel plate 304.

[0049] The height of the embedded steel plate 301 and the connecting steel plate 302 at the lower end of the steel column 3 are both higher than the height of the reinforcing steel plate 303 and the stop steel plate 304. That is, the embedded steel plate 301 and the connecting steel plate 302 can form a locking and limiting structure. The embedded steel plates 301 on both sides can form a primary locking position, capable of locking the stop steel plate 304 at the upper end of the steel column 3. A secondary locking position is formed between the connecting steel plates 302 on both sides of the reinforcing steel plate 303, meaning the locking groove 306 can lock the reinforcing steel plate 303 at the upper end of the steel column 3.

[0050] During assembly, the adjacent edge steel column-composite wall structural units 1 can be easily fixed by inserting the steel column 3, and the connection is very strong and reliable.

[0051] Based on the above embodiments, as a preferred embodiment, the vertical steel bars 201 on the double-leaf cavity composite wall 2 extend from the upper and lower ends of the wall, and the vertical steel bars 201 between adjacent double-leaf cavity composite walls 2 overlap.

[0052] Preferably, the lap length of the vertical reinforcing bar 201 is less than the length of the steel column 3 extending out of the double-leaf cavity composite wall 2, and the vertical reinforcing bars 201 are staggered by one reinforcing bar diameter when horizontally arranged in the edge steel column-composite wall structural unit 1 at odd and even positions.

[0053] Furthermore, the horizontal gap formed between the adjacent edge-type steel column-composite wall structural units 1 is higher than the horizontal height of the floor slab, that is, after hoisting, the bottom surface of the upper double-leaf cavity composite wall is higher than the floor elevation.

[0054] As a preferred implementation of the prefabricated edge-type steel column-composite wall structure system, it adopts the method of prefabrication in the component factory and on-site hoisting construction. It mainly consists of edge-type steel column-composite wall structural units and steel connecting beams. The steel connecting beams are not shown in the attached drawings.

[0055] The edge-type steel column-composite wall structure unit is prefabricated by a prefabrication plant and mainly consists of three parts: cross-shaped steel columns, double-leaf hollow composite walls 2, and joint steel beams 4.

[0056] The double-leaf hollow composite wall 2 is composed of inner and outer precast reinforced concrete slabs and a central cavity. The inner and outer reinforced concrete slabs are approximately 5cm thick, and the longitudinal reinforcement bars inside the inner and outer slabs extend out of the wall, with the extension length meeting the requirements for longitudinal reinforcement lap splicing. The height of the double-leaf hollow composite wall should be the floor height minus the reinforcement lap splicing length.

[0057] The cruciform steel columns are pre-embedded in the inner and outer precast reinforced concrete walls, located in the central cavity of the double-leaf cavity composite wall, and spaced apart on the left and right at the shear wall confinement edge column positions. In other words, the cruciform steel columns replace the original edge columns composed of steel reinforcement bundles. The upper part of the web of the cruciform steel columns has holes; after the holes are installed, the minimum cross-section should meet the structural design requirements. The webs at the ends of the cruciform steel columns are not flush. The bottom of the upper cruciform steel columns has a lower web in the east-west or other directions than in the north-south or other directions, and the corresponding north-south web has a gap in the middle, the gap width being greater than the thickness of the steel column plate. The top of the lower cruciform steel columns has a higher web in the north-south or other directions than in the east-west or other directions. Slender studs are arranged on the flanges of the cruciform steel columns.

[0058] The outer edges of the upper and lower flanges of the joint steel beam 4 are welded with shear studs, the strength grade of which is not lower than Q235 and not higher than Q420. The root of the joint steel beam 4 is welded to the cross-shaped steel column, and the two sides are welded to the steel mesh of the double-layer hollow composite wall or pre-embedded inside the double-layer hollow composite wall.

[0059] The connection between the edge-type steel column-composite wall structural units 2 and the connection between the edge-type steel column-composite wall structural units 2 and the steel connecting beams are respectively rigidly connected by pre-embedded joint steel beams and pre-embedded joint steel beams and steel connecting beams by bolts or welding.

[0060] The horizontal joints between the edge-type steel column-composite wall structural units are connected by first inserting and then welding; the longitudinal reinforcement of the wall is connected by lap splicing.

[0061] The described edge-type steel column-composite wall structure system uses one edge-type steel column-composite wall structural unit 2 as a basic unit. The upper and lower basic units are connected by exposed steel columns through insertion or welding after insertion; the basic units on the same floor are connected by pre-embedded joint steel beams. The steel columns and joint steel beams form a frame, reducing the reliance of the double-leaf cavity composite wall system on lateral supports.

[0062] A construction method for a prefabricated edge-type steel column-composite wall structure system includes a prefabrication step for prefabricated edge-type steel column-composite wall units and an on-site installation step.

[0063] The prefabrication steps for the assembled edge-type steel column-composite wall unit include:

[0064] Step 1: Lay and weld the steel mesh inside a concrete slab.

[0065] Step 2: Weld the cross-shaped steel column to the predetermined position in the steel mesh; weld the joint steel beam to the cross-shaped steel column.

[0066] Step 3: Lay out and weld the steel mesh inside the other concrete slab.

[0067] Step 4: Erect the side formwork of the composite wall unit and cast it into shape; the vertical reinforcement of the composite wall and the cross-shaped steel columns in the cavity of the double-sided composite wall must extend out of the wall.

[0068] The on-site installation steps include:

[0069] Step 1: Transport the prefabricated composite wall units to the site and begin the on-site installation process.

[0070] Step 2: Remove the loose slurry and rust from the pre-reserved steel bars and cross-shaped steel columns of the lower-level poured wall, and adjust them into place.

[0071] Step 3: Hoist the upper composite wall unit to the top of the lower connecting wall. Gradually insert the cross-shaped steel column at the bottom of the upper composite wall unit into the lower reserved cross-shaped steel column. After initial connection, make corrections and weld them firmly after corrections are completed.

[0072] Step 4: Tie and lap the vertical reinforcing bars of the upper composite wall with the reserved vertical reinforcing bars of the lower composite wall in the horizontal gap formed by the upper and lower steel columns.

[0073] Step 5: Connect the joint steel beams between the composite wall units to form an overall frame.

[0074] Step 6: Erect the top slab formwork and lay the reinforcing bars, or lay the precast concrete floor slab.

[0075] Step 7: Use L-shaped or C-shaped aluminum film or steel mold as templates for the horizontal gap formed by the upper and lower steel columns described in Step 4, and support and reinforce it.

[0076] Step 8: Repeat steps 1 to 7 above to complete the construction of the entire floor's prefabricated edge steel column-double-sided composite wall system.

[0077] Step 12: Pour the floor concrete, and then vibrate and cure it.
