Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to a prefabricated wall structure. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. This construction method is fast, efficient, environmentally friendly, and has low production costs, thus gaining widespread application.

[0003] Most prefabricated buildings in the prior art consist of flat wall panels, which need to be connected to beam and column structures during installation. However, some prefabricated wall structures have corners. For example, Chinese Patent No. CN215563519U, published on January 18, 2022, discloses an L-shaped shear wall prefabricated panel suitable for corners in prefabricated buildings. It includes an upper mounting base, a lower mounting base, a steel reinforcement frame, an outer wall panel, an inner wall panel, and connecting components. The outer wall panel is L-shaped. The steel reinforcement frame is set inside the outer wall panel and includes X-direction steel bars, Y-direction steel bars, and Z-direction steel bars that are arranged perpendicularly in an array, as well as diagonal steel bars set at the corners of the outer wall panel. The inner wall panel is fixedly connected to the steel reinforcement frame through connecting components and is arranged parallel to the inner side of the outer wall panel. The upper mounting base and the lower mounting base are respectively set at the top and bottom of the steel reinforcement frame. When assembling the prefabricated panel, the lower mounting base of the upper prefabricated panel and the upper mounting base of the lower prefabricated panel cooperate with each other for assembly and fixation.

[0004] The above application improves the strength of the corner of the wall panel by setting diagonal steel bars at the corner of the wall panel. However, it does not significantly improve the tensile and seismic resistance of the wall panel and the inner wall panel for the corner connection. The wall panel is still prone to cracking under some large vibrations. Therefore, it is necessary to design a prefabricated wall structure with high crack resistance and seismic strength. Utility Model Content

[0005] This application provides a prefabricated wall structure with high crack resistance and seismic strength.

[0006] A prefabricated wall structure includes a wall panel body, wherein the wall panel body includes a first wall panel and a second wall panel connected to each other, the first wall panel and the second wall panel are arranged at an angle, and transverse steel bars and longitudinal steel bars are arranged through the first wall panel and the second wall panel. Diagonal steel bars are provided in both the first wall panel and the second wall panel, and the multiple diagonal steel bars are arranged parallel to the first wall panel or the second wall panel, and the diagonal steel bars are arranged towards the side where the first wall panel and the second wall panel are connected.

[0007] Preferably, the main body of the wall panel is a cast concrete wall panel, and a reinforcing cage is provided at the connection position between the first wall panel and the second wall panel. A first sleeve is provided inside the reinforcing cage, and a positioning hole is provided on the side of the first sleeve. The inclined reinforcing bar can be connected to the positioning hole.

[0008] Preferably, the first sleeve is provided with connecting steel bars, and the side of the first sleeve is provided with a first grouting pipe and a first grout outlet pipe, the ends of the first grouting pipe and the first grout outlet pipe extending out of the first wall panel or the second wall panel.

[0009] Preferably, the connecting steel bars are arranged vertically and the height of the connecting steel bars is equal to the height of the longitudinal steel bars.

[0010] Preferably, the horizontal cross-sectional views of the first grouting pipe and the first grout outlet pipe are both in the shape of "┏" or "┓", and the ends of the first grouting pipe and the first grout outlet pipe simultaneously pass through the first wall panel or the second wall panel.

[0011] Preferably, the first wall panel and the second wall panel are arranged at a right angle.

[0012] Preferably, the transverse reinforcement, the longitudinal reinforcement, and the diagonal reinforcement are all hot-rolled ribbed steel bars, with the diagonal reinforcement located between the transverse reinforcement and the longitudinal reinforcement.

[0013] Preferably, a second sleeve is provided at the lower part of both the first wall panel and the second wall panel, and there are multiple second sleeves, each of which is provided with a second grouting hole and a second grout outlet hole.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. This application uses a first wall panel and a second wall panel arranged at an angle, and provides transverse and longitudinal reinforcing bars and diagonal reinforcing bars within the first and second wall panels. The transverse and longitudinal reinforcing bars can improve the connection strength at the joint, and the diagonal reinforcing bars can improve the overall tensile, crack resistance and seismic performance of the first and second walls, ensuring the stability of the wall structure support.

[0016] 2. By setting a reinforcing cage at the connection between the first wall panel and the second wall panel, the strength of the connection can be enhanced. At the same time, a first sleeve is set inside the reinforcing cage, and grouting into the first sleeve can improve the connection strength at the corner. The first sleeve is also provided with positioning holes, which can be used to fix the diagonal reinforcing bars for easy installation. By setting a first grouting pipe and a first grout outlet pipe on the first sleeve, and setting connecting reinforcing bars inside the first sleeve, the connection strength after grouting is guaranteed and the stability is improved.

[0017] 3. By setting the connecting steel bars, transverse steel bars and longitudinal steel bars as hot-rolled ribbed steel bars, the connection performance of precast concrete casting is improved. At the same time, the diagonal steel bars are located between the transverse steel bars and longitudinal steel bars to ensure the internal support stability of the first wall panel and the second wall panel.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application discloses a prefabricated wall structure.

[0024] Reference Figures 1 to 3 A precast wall structure includes a wall panel body 1, which is a cast concrete wall panel. The wall panel body 1 includes a first wall panel 101 and a second wall panel 102 connected to each other. The first wall panel 101 and the second wall panel 102 are arranged at a right angle. Transverse reinforcing bars 2 and longitudinal reinforcing bars 3 are inserted through the first wall panel 101 and the second wall panel 102. Diagonal reinforcing bars 4 are provided in both the first wall panel 101 and the second wall panel 102. Multiple diagonal reinforcing bars 4 are arranged parallel to the first wall panel 101 or the second wall panel 102, facing the side where the first wall panel 101 and the second wall panel 102 are connected. Specifically, in this embodiment, the transverse reinforcing bars 2, the longitudinal reinforcing bars 3, and the diagonal reinforcing bars 4 are all hot-rolled ribbed steel bars, and the diagonal reinforcing bars 4 are located between the transverse reinforcing bars 2 and the longitudinal reinforcing bars 3. The diagonal reinforcing bars 4 are prestressed steel bars, which can improve the overall tensile strength, crack resistance, and seismic performance of the first wall 101 and the second wall 102, and improve the stability of the wall structure.

[0025] Reference Figure 3A reinforcing cage 5 is provided at the connection position of the first wall panel 101 and the second wall panel 102. A first sleeve 6 is provided inside the reinforcing cage 5. A positioning hole is provided on the side of the first sleeve 6, and the inclined reinforcing bar 4 can be connected to the positioning hole. A connecting reinforcing bar 7 is provided inside the first sleeve 6. A first grouting pipe 601 and a first grout outlet pipe 602 are provided on the side of the first sleeve 6. The ends of the first grouting pipe 601 and the first grout outlet pipe 602 extend out of the first wall panel 101 or the second wall panel 102. Specifically, in this embodiment, the horizontal cross-sectional view of the first grouting pipe 601 and the first grout outlet pipe 602 are both in the shape of "┏" or "┓". The ends of the first grouting pipe 601 and the first grout outlet pipe 602 simultaneously pass through the first wall panel 101 or the second wall panel 102, so that grout can be injected into the first sleeve 6 through the first grouting pipe 601 and the first grout outlet pipe 602, thereby fixing the connecting reinforcing bar 7 and ensuring the stability of the connection support at the corner.

[0026] Reference Figure 1 and Figure 2 The connecting steel bar 7 is set vertically and its height is equal to that of the longitudinal steel bar 3. The lower part of the first wall panel 101 and the second wall panel 102 are both provided with a second sleeve. There are multiple second sleeves and the second sleeves are provided with a second grouting hole 8 and a second grout outlet hole 9.

[0027] The implementation principle is as follows: This application sets up a precast concrete wall panel main body 1, which can directly construct right-angle walls with corners, effectively improving construction efficiency. At the same time, transverse steel bars 2 and longitudinal steel bars 3 are set in the first wall panel 101 and the second wall panel 102, and diagonal steel bars 4 are set in the first wall panel 101 and the second wall panel 102. The transverse steel bars 2 and longitudinal steel bars 3 can improve the connection performance and strength at the corner connection, and the diagonal steel bars 4 can improve the overall tensile, crack resistance and seismic performance of the first wall 101 and the second wall 102, ensuring the support stability of the wall structure.
