Abstract
Description
Technical Field
[0001] This application relates to the technical field of wall panels, and in particular to a prefabricated wall panel. Background Technology
[0002] Prefabricated wall panels are large, prefabricated panels manufactured in a factory and transported to the site for mechanized installation to form walls. Through modular design and factory assembly line production, prefabricated wall panels significantly shorten construction time. Generally, prefabricated wall panels are connected to a steel structural frame during installation to ensure structural stability.
[0003] In related technologies, one can refer to Chinese patent with authorization announcement number CN217711471U, which discloses a prefabricated wall panel, including a first foamed ceramic panel and a second foamed ceramic panel. The first foamed ceramic panel and the second foamed ceramic panel are bonded together by a mortar layer. A steel keel is provided in the mortar layer. Coaxial mounting holes are provided on the first foamed ceramic panel and the second foamed ceramic panel. A steel pipe is provided in the mounting holes.
[0004] However, when assembling the prefabricated wall panels, since the first and second foamed ceramic panels are connected to the steel keel through a mortar layer, the verticality of the wall panels during subsequent installation largely depends on the initial positional relationship between the steel keel and the first and second foamed ceramic panels. It is difficult to adjust the verticality of the wall panels during subsequent installation, and the large overall mass of the panels makes the adjustment very labor-intensive and inconvenient. Utility Model Content
[0005] To ensure the verticality of the wall panel during installation, this application provides a prefabricated wall panel.
[0006] This application provides a prefabricated wall panel, which adopts the following technical solution:
[0007] A prefabricated wall panel includes a keel, which comprises two horizontally arranged steel bars and a plurality of support columns arranged between the two steel bars. Connecting components are provided on the steel bars, and the two steel bars are respectively connected to an upper floor slab and a lower floor slab via the connecting components. The plurality of support columns are arranged vertically between the two steel bars. The longitudinal section of the steel bars is C-shaped. A plurality of inner wall panels are filled between two steel bars, and the inner wall panels are located between two adjacent support columns. Installation components are provided on the outer walls of the two steel bars, and outer wall panels are covered on the outer walls of the two steel bars by the installation components.
[0008] By adopting the above technical solution, the keel is set as a combination of two steel bars and several support columns. The wall panels can be positioned by the "C"-shaped steel bars, so that the inner wall panels located inside the steel bars can remain vertical with the support columns. Then the outer wall panels can be tightly attached to the outer walls of the upper and lower steel bars, thereby ensuring the surface verticality of the outer wall panels and reducing the probability of tilting during the installation of prefabricated wall panels. The wall panels are divided into inner and outer wall panels for segmented verticality adjustment, which greatly reduces the workload of adjusting the verticality of the wall panels.
[0009] Optionally, the connection component includes:
[0010] Expansion screws, which are driven into the floor slab;
[0011] The first leveling nut is threaded onto the expansion screw, and the steel bar has a connecting hole for the expansion screw to pass through. The steel bar is placed on the first leveling nut.
[0012] The second leveling nut is threaded onto the steel bar and abuts against the steel bar.
[0013] By adopting the above technical solution, expansion screws are driven into the floor slab, then the first leveling nut is threaded onto the expansion screw, the steel bar is placed on the first leveling nut, and then the second leveling nut is screwed onto the expansion screw and pressed against the steel bar, thus completing the installation of the steel bar on the floor slab.
[0014] Optionally, the steel bar has a raised portion on the side that contacts the expansion screw, extending away from the floor slab, and the connecting hole is formed on the raised portion.
[0015] By adopting the above technical solution, a protrusion is formed on the side of the steel bar that contacts the expansion screw, which greatly increases the contact area between the steel bar and the concrete or mortar layer poured on the floor slab, thereby improving the structural strength and stability of the steel bar.
[0016] Optionally, the installation components include:
[0017] The mounting plate is disposed on the side of the outer wall panel and abuts against the outer wall of the steel strip;
[0018] The mounting screw passes through the mounting plate and strikes the outer wall of the steel strip.
[0019] By adopting the above technical solution, mounting plates are installed on the outer wall of the steel strip, and mounting screws are used to fix the mounting plates to the steel strip, thereby completing the fixing of the exterior wall panel on the outer wall of the steel strip.
[0020] Optionally, an installation groove is provided on the side of the exterior wall panel where the installation piece is installed, and an installation block is provided on the side of the exterior wall panel opposite to the side where the installation piece is installed. In two adjacent exterior wall panels, the installation block on one exterior wall panel is inserted into the installation groove on the other installation block.
[0021] By adopting the above technical solution, an installation groove is opened at one end of the exterior wall panel and an installation block is installed at the other end, so that when several exterior wall panels are installed, adjacent exterior wall panels can be interlocked end to end. This not only ensures the continuity and flatness between the exterior wall panels, but also greatly improves the convenience of installation and work efficiency.
[0022] Optionally, the mounting block has an arc-shaped first guide surface at one end where it is inserted into the mounting groove, and the inner bottom wall of the mounting groove has a second guide surface that matches the first guide surface.
[0023] By adopting the above technical solution, an arc-shaped first guide surface is opened on the mounting block, and a second guide surface is opened on the bottom wall of the mounting groove. The guidance of the first and second guide surfaces can greatly improve the working efficiency when the mounting block is inserted into the mounting groove.
[0024] Optionally, the outer wall panel has a clearance groove on one end where the mounting block is located, for mounting pieces on adjacent outer wall panels to be placed.
[0025] By adopting the above technical solution, clearance grooves are opened in the exterior wall panels, so that the surfaces of each exterior wall panel can be completely flat when they are connected to each other.
[0026] Optionally, thermal insulation cotton is laid in the gap between the outer wall panel and the inner wall panel.
[0027] By adopting the above technical solution, thermal insulation cotton is laid in the gap between the outer wall panel and the inner wall panel, which greatly improves the overall thermal insulation effect of the wall and fills the gap between the outer wall panel and the inner wall panel, thereby improving the overall stability of the wall.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. By setting the keel as a combination of two steel bars and several support columns, the wall panels can be positioned by the "C"-shaped steel bars, so that the inner wall panels located inside the steel bars can remain vertical under the support columns. Then the outer wall panels can be tightly attached to the outer walls of the upper and lower steel bars, thereby ensuring the surface verticality of the outer wall panels and reducing the probability of tilting during the installation of prefabricated wall panels. The wall panels are divided into inner wall panels and outer wall panels for segmented verticality adjustment, which greatly reduces the workload of adjusting the verticality of the wall panels.
[0030] 2. The installation of the steel bar on the floor slab is completed by driving expansion screws into the floor slab, then threading the first leveling nut onto the expansion screws, placing the steel bar on the first leveling nut, and then tightening the second leveling nut onto the expansion screws and pressing it against the steel bar.
[0031] 3. By laying insulation cotton in the gap between the exterior wall panel and the interior wall panel, the overall insulation effect of the wall is greatly improved, and the gap between the exterior wall panel and the interior wall panel is filled, which improves the overall stability of the wall.

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.
[0037] This application discloses a prefabricated wall panel.
[0038] Reference Figure 1 and Figure 2 The prefabricated wall panel includes a keel 1, which comprises two horizontally arranged steel bars 11 and several support columns 12 installed between the two steel bars 11. Connecting components 2 are provided on the steel bars 11, and the two steel bars 11 are respectively connected to the upper floor slab 15 and the lower floor slab 15 via the connecting components 2. The several support columns 12 are fixed to the opposite side walls of the two steel bars 11 and are arranged vertically. The longitudinal section of the steel bars 11 is C-shaped. Several inner wall panels 13 are filled between the two steel bars 11, and the inner wall panels 13 are located between two adjacent support columns 12. Installation components 3 are provided on the outer walls of the two steel bars 11, and several outer wall panels 14 are covered on the outer walls of the two steel bars 11 via the installation components 3.
[0039] Reference Figure 1 and Figure 2 The connecting assembly 2 includes an expansion screw 21, a first leveling nut 22, and a second leveling nut 23. The expansion screw 21 is driven into the floor slab 15. The first leveling nut 22 is threaded onto the expansion screw 21. A connecting hole for the expansion screw 21 to pass through is provided on the steel strip 11, and the steel strip 11 is placed on the first leveling nut 22. The second leveling nut 23 is threaded onto the steel strip 11 and abuts against it. A protrusion 24 is formed on the side of the steel strip 11 that contacts the expansion screw 21, extending away from the floor slab 15. The connecting hole is located on the protrusion 24. The protrusion 24 on the side of the steel strip 11 that contacts the expansion screw 21 greatly increases the contact area between the steel strip 11 and the concrete or mortar layer 16 poured on the floor slab 15, thereby improving the structural strength and stability of the steel strip 11.
[0040] Reference Figure 1 and Figure 3 The mounting assembly 3 includes a mounting plate 31 and mounting screws 32. The mounting plate 31 is fixedly mounted on the side of the exterior wall panel 14 and abuts against the outer wall of the steel strip 11. The mounting screws 32 pass through the mounting plate 31 and strike the outer wall of the steel strip 11. The mounting plate 31 is fixed to the outer wall of the steel strip 11 by the mounting screws 32. A mounting groove 33 is provided on the side of the exterior wall panel 14 where the mounting plate 31 is mounted. A mounting block 34 is fixedly mounted on the outer wall of the exterior wall panel 14 opposite to the side where the mounting plate 31 is mounted. In two adjacent exterior wall panels 14, the mounting block 34 on one exterior wall panel 14 is inserted into the mounting groove 33 on the other mounting block 34.
[0041] Reference Figure 3 By using mounting blocks 34 and mounting grooves 33, adjacent exterior wall panels 14 can be interlocked end-to-end, ensuring not only the continuity and flatness of the exterior wall panels 14 but also greatly improving installation convenience and work efficiency. The end of the mounting block 34 that interlocks with the mounting groove 33 has an arc-shaped first guide surface 35, and the inner bottom wall of the mounting groove 33 has a second guide surface 36 that fits with the first guide surface 35. The guidance of the first guide surface 35 and the second guide surface 36 greatly improves the efficiency of interlocking the mounting block 34 with the mounting groove 33.
[0042] Reference Figure 3 The outer wall panel 14 has a recess 37 on one end where the mounting block 34 is provided, which allows the mounting pieces 31 on adjacent outer wall panels 14 to be placed. This ensures that the surfaces of each outer wall panel 14 are completely flat when they are connected to each other.
[0043] Reference Figure 1Thermal insulation cotton 38 is laid in the gap between the outer wall panel 14 and the inner wall panel 13. The installation of thermal insulation cotton 38 not only improves the overall thermal insulation effect of the wall, but also fills the gap between the outer wall panel 14 and the inner wall panel 13, thereby improving the overall stability of the wall.
[0044] The working principle of this application embodiment is as follows:
[0045] By setting the keel 1 as a combination of two steel bars 11 and several support columns 12, the wall panel can be positioned by the "C"-shaped steel bars 11, so that the inner wall panel 13 located inside the steel bars 11 can remain vertical under the support columns 12. Then the outer wall panel 14 can be tightly attached to the outer wall of the upper and lower steel bars 11, thereby ensuring the surface verticality of the outer wall panel 14 and reducing the probability of tilting during the installation of the prefabricated wall panel. The verticality of the wall panel is adjusted in sections by dividing the wall panel into two parts, the inner wall panel 13 and the outer wall panel 14, which greatly reduces the workload of adjusting the verticality of the wall panel.
[0046] 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.
