Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to an assembled earthquake-resistant wall structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. This construction method is fast, efficient, environmentally friendly, and has low production costs. It has been widely used around the world.

[0003] Prefabricated buildings can be divided into block buildings, panel buildings, box-type buildings and frame panel buildings according to the material structure. Among them, panel buildings are assembled from prefabricated interior and exterior wall panels, floor slabs and roof panel lighting panels, so they are also called large-panel buildings. They are the main type of fully prefabricated buildings in industrialized system buildings.

[0004] The current prefabricated walls include interior wall panels and exterior wall panels. The interior wall panels are mostly solid or hollow panels of reinforced concrete; the exterior wall panels are mostly reinforced concrete composite panels with an insulation layer, or wall panels with exterior facings made of lightweight aggregate concrete, foam concrete or macroporous concrete. The current prefabricated wall panels are mostly square flat plate structures. During assembly, formwork is set at the steel bars between adjacent wall panels for pouring to achieve connection.

[0005] The wall panels processed by the above method have poor integrity and average seismic resistance, especially at some corners or corners, where multiple wall panels at different angles are cast by formwork. The operation is complicated and the assembly effect is poor, which affects the use. Therefore, it is necessary to design an assembled seismic wall structure that is easy to assemble and has good seismic resistance. Utility Model Content

[0006] The present application provides an assembled earthquake-resistant wall structure that is easy to assemble and has good earthquake-resistant effect.

[0007] The present application provides an assembled earthquake-resistant wall structure adopting the following technical solution:

[0008] An assembled earthquake-resistant wall structure comprises a first wall panel and a second wall panel which are spliced ​​to each other, wherein the first wall panel is a right-angle bent plate and the horizontal cross-section of the first wall panel is L-shaped, the second wall panel is a flat plate structure and the second wall panel is connected to both ends of the first wall panel, adhesive plates and decorative plates are arranged on the outer sides of the first wall panel and the second wall panel, the adhesive plates and decorative plates on the first wall panel are both L-shaped, the size of the first wall panel or the second wall panel is smaller than the size of the adhesive plate arranged thereon, the width of the decorative plate is equal to the width of the adhesive plate and the decorative plate is horizontally offset from the adhesive plate, and the ends of adjacent adhesive plates or adjacent decorative plates are connected when the first wall panel and the second wall panel are assembled.

[0009] Preferably, transverse steel bars are provided on both the first wall panel and the second wall panel. The transverse steel bars are arranged horizontally and both ends of the transverse steel bars pass through the first wall panel and the second wall panel. The ends of the transverse steel bars are arranged with bends. The heights of the transverse steel bars on the first wall panel and the second wall panel are equal and the bending directions of the transverse steel bars are the same.

[0010] Preferably, the length of the transverse reinforcement is smaller than the width of the bonding plate.

[0011] Preferably, the upper parts of both ends of the first wall panel and the second wall panel are provided with formwork connection parts, the formwork connection parts extend out of the first wall panel or the second wall panel and are located on the inner side of the adhesive plate, the transverse steel bars pass through the formwork connection parts, and a plurality of formwork fixing holes are provided on the edges of the formwork connection parts, the edges of both ends of the first wall panel and the edges of both ends of the second wall panel.

[0012] Preferably, vertical steel bars are provided on both the first wall panel and the second wall panel, and the vertical steel bars vertically penetrate the first wall panel and the second wall panel.

[0013] Preferably, both the first wall panel and the second wall panel are provided with reserved grouting holes.

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

[0015] 1. In the present application, by providing a first wall panel with a right-angle turn, the first wall panel of the L-shaped structure can provide stable support, which can improve the overall earthquake resistance of the wall. At the same time, the two ends of the first wall panel are connected to the second wall panel. During formwork casting, it is only necessary to install the formwork on one plane, which is convenient for construction. By providing an adhesive plate and a decorative plate on the outer sides of the first wall panel and the second wall panel and the size of the adhesive plate is larger than the first wall panel or the second wall panel, the ends of the adhesive plates between the adjacent first wall panels and the second wall panels are connected during assembly. At the same time, due to the horizontal staggered arrangement of the decorative plate and the adhesive plate, the outer side of the adhesive plate on the first wall panel is connected to the inner side of the decorative plate on the adjacent second wall panel during assembly, which can play a role in limiting and side support, and can ensure that the vertical direction is installed in place, which is convenient for construction and ensures the wall strength.

[0016] 2. In the present application, transverse steel bars are arranged on both the first wall panel and the second wall panel, and bends are arranged on the transverse steel bars. The heights of the transverse steel bars on the first wall panel and the second wall panel are consistent and the bending directions are the same, which is convenient for binding and fixing and construction. At the same time, the length of the transverse steel bars is less than the width of the adhesive plate, which avoids mutual interference between the first wall panel and the second wall panel during hoisting and installation, thereby ensuring the installation effect.

[0017] 3. By providing protruding formwork connections at both ends of the first wall panel and the second wall panel and the formwork connections are located on the inner side of the adhesive plate, the formwork connections between the adjacent first wall panel and the second wall panel and their sides constitute a casting space during assembly, and casting is performed by tying steel bars and installing formwork. Due to the existence of the formwork connections, the width of the lower part of the casting connection area after molding is greater than the width of the upper part, thereby ensuring the connection strength and improving the earthquake resistance effect.

The size of the first wall panel 1 or the second wall panel 2 is smaller than the size of the adhesive plate 3 set thereon. The width of the decorative plate 4 is equal to the width of the adhesive plate 3 and the decorative plate 4 is horizontally offset from the adhesive plate 3. When the first wall panel 1 and the second wall panel 2 are assembled, the ends of the adjacent adhesive plates 3 or adjacent decorative plates 4 are connected. Since the adhesive plate 3 and the decorative plate 4 are horizontally offset, when assembled, the outer side of the adhesive plate 3 on the first wall panel 1 is connected to the inner side of the decorative plate 4 on the adjacent second wall panel 2, which can play the role of limiting and side support, and can ensure that the vertical direction is installed in place, facilitating construction while ensuring the strength of the wall.

[0026] Reference Figures 1 to 3 , transverse steel bars 5 are provided on both the first wall panel 1 and the second wall panel 2, the length of the transverse steel bars 5 is less than the width of the bonding plate 3, the transverse steel bars 5 are horizontally arranged and both ends of the transverse steel bars 5 pass through the first wall panel 1 and the second wall panel 2, the ends of the transverse steel bars 5 are bent, the heights of the transverse steel bars 5 on the first wall panel 1 and the second wall panel 2 are equal and the bending directions of the transverse steel bars 5 are the same; vertical steel bars 8 are provided on both the first wall panel 1 and the second wall panel 2, and the vertical steel bars 8 vertically pass through the first wall panel 1 and the second wall panel 2.

[0027] Reference Figure 1 and Figure 4 A formwork connection part 6 is provided at the upper part of both ends of the first wall panel 1 and the second wall panel 2. The formwork connection part 6 extends out of the first wall panel 1 or the second wall panel 2 and is located on the inner side of the adhesive plate 3. The transverse steel bar 5 passes through the formwork connection part 6. A plurality of formwork fixing holes 7 are provided on the edges of the formwork connection part 6, the edges at both ends of the first wall panel 1 and the edges at both ends of the second wall panel 2. Reserved grouting holes 9 are provided on the first wall panel 1 and the second wall panel 2.

[0028] The implementation principle is as follows: the present application sets a first wall panel 1 with a right-angle turn, and the first wall panel 1 of the L-shaped structure can provide stable support, which can improve the overall earthquake resistance of the wall. At the same time, the two ends of the first wall panel 1 are connected to the second wall panel 2. During formwork casting, it is only necessary to install the formwork on one plane, which is convenient for construction. By setting an adhesive plate 3 and a decorative plate 4 on the outer sides of the first wall panel 1 and the second wall panel 2, and the size of the adhesive plate 3 is larger than the first wall panel 1 or the second wall panel 2, the ends of the adhesive plates 3 between the adjacent first wall panels 1 and the second wall panels 2 are connected during assembly. At the same time, due to the horizontal staggered arrangement of the decorative plate 4 and the adhesive plate 3, the outer side of the adhesive plate 3 on the first wall panel 1 is connected to the inner side of the decorative plate 4 on the adjacent second wall panel 2 during assembly, which can play a role in limiting and side support, and can ensure that the vertical direction is installed in place, which is convenient for construction and ensures the wall strength.

[0029] When assembling the present application, it is necessary to first hoist and install the first wall 1. Since the cross-section of the first wall 1 is L-shaped, its support is stable. Then, the second wall 2 is installed at both ends of the first wall 1. During the hoisting process, the construction personnel can position and install the second wall 2 according to the decorative panel 4 or the adhesive panel 3 on the second wall 2 to ensure that the second wall 2 is accurately placed. Then, the transverse steel bars 5 at the ends of the first wall panel 1 and the second wall panel 2 are tied. During the tying process, vertical connecting steel bars need to be placed in the transverse steel bars 5 for fixing. Then, a formwork is set up between the first wall 1 and the second wall 2. The formwork is connected to the two ends of the first wall 1, the two ends of the second wall 2 and the formwork connection part 6. Finally, concrete is poured in the formwork. Due to the existence of the formwork connection part 6, the width of the lower part of the casting area after molding is greater than the width of the upper part, which ensures the connection strength of the first wall 1 and the second wall 2, while improving the integrity of the wall and the earthquake resistance.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
