Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to an anti-deformation assembled wall panel. Background Art

[0002] In prefabricated buildings, exterior wall panels are not constructed using masonry. Currently, the market primarily utilizes prefabricated integral exterior wall panels and prefabricated strips. However, cracks frequently develop between strips and between strips and main structural components during building operation, and repeated repairs are ineffective. Under external forces such as wind loads, the main structure experiences greater horizontal deformation than other structural forms. This horizontal deformation is reflected between the main structural components and the wall panels, and between the wall panels themselves, causing misalignment and cracks.

[0003] Document CN117403804B discloses a new type of prefabricated exterior wall panel, comprising a lightweight steel keel, artificial stone panels, connectors, flexible caulking material, rock wool insulation, a double-layer gypsum inner panel, and a steel structure. The connectors consist of a base plate, a cross plate, an upper connecting plate, and a lower connecting plate. The base plate is provided with a third bolt hole for connection to the lightweight steel keel, and injection holes are provided through the upper connecting plate, cross plate, and base plate. Flexible caulking material is injected through the injection holes to fill the gaps between the connectors and the panels, improving the deformation resistance between the panels.

[0004] However, the device still has the following problems: the volume of the cavity between the upper and lower connecting plates and the bottom plate and the cavity in the stone plate seam is too large, and a large amount of caulking material needs to be filled; and filling the stone plate seam and filling the cavity between the upper and lower connecting plates and the bottom plate need to be carried out in two steps, which is cumbersome. Utility Model Content

[0027] This embodiment provides an anti-deformation assembled wall panel, including a keel 11, a wall panel 12, and a connector 2 provided on the keel 11 and used for mounting the wall panel 12.

[0028] In this embodiment, the keel 11 comprises a vertical keel 112 and a through-keel 113, which extends perpendicularly within and through the vertical keel 112. Both the vertical keel 112 and the through-keel 113 are constructed of U-shaped lightweight steel keels. The lower end of the vertical keel 112 slots vertically into a groove in the underlying ground keel (also a U-shaped lightweight steel keel). The bottom panel of the vertical keel 112 is provided with a square hole through which the through-keel 113 passes horizontally and is secured to the vertical keel 112. After installation, the through-keel opening faces upward. The resulting keel 11 is structurally stable, minimizing deformation under external forces.

[0029] In this embodiment, the end of the wall panel 12 is provided with a connecting groove 121. Specifically, the blind corners of the wall panel 12 are all provided with a connecting groove 121, and the wall panel 12 is engaged with the connecting member 2 through the connecting groove 121, thereby being installed on the connecting member 2.

[0030] In this embodiment, the connector 2 includes a base plate 21, a mounting hole 22 provided on the base plate 21, two fixing plates 23 provided on the base plate 21 and located on either side of the mounting hole 22, an upper connecting plate 24 and a lower connecting plate 25 mounted on the two fixing plates 23 and arranged opposite each other, and a support plate 26 provided on the base plate 21 and located between the upper connecting plate 24 and the lower connecting plate 25 for supporting the wall panel 12. The upper connecting plate 24 and the lower connecting plate 25 are both U-shaped plates, with the upper connecting plate 24 opening facing upward and the lower connecting plate 25 opening facing downward (i.e., the two openings are arranged in opposite directions). The two side plates of the U-shaped plate protrude from the base plate, thereby ensuring that when the bottom surface of the connecting groove 121 abuts the bottom plate of the U-shaped plate, the side plates of the U-shaped plate engage with the side edges of the wall panel 12, thereby restricting the position of the wall panel 12, so that the two wall panels mounted on the same connecting plate are close to each other, effectively controlling the size of the gap.

[0031] It is worth noting that the ends of the fixing plates 23 are recessed a distance from the bottom plates of the upper connecting plates 24 and the lower connecting plates 25. Similarly, the portion of the back of the wall panel 12 that serves as the edge of the connecting groove 121 is also recessed a distance from the front edge, thereby ensuring that the fixing plates 23 do not interfere with the installation of the wall panel 12. Compared to the prior art, this embodiment uses two fixing plates 23 to fix the same connecting plate. The advantages are: first, it increases the support strength of the connecting plate and improves the structural stability of the device; second, it provides space for installing bolts in the central mounting holes, ensuring that the strength between the connector and the keel remains unchanged while reducing the number of mounting holes provided on the bottom plate, reducing the difficulty of installation. At the same time, the reduced number of holes can also increase the strength of the structure.

[0032] In this embodiment, the keel 11 is provided with a first injection hole 111, and the connector 2 is provided with a second injection hole 27 that penetrates the base plate 21, the fixing plate 23, the upper connecting plate 24, and the lower connecting plate 25 and matches the first injection hole 111. The provision of two injection holes allows the flexible caulking material to enter the gap between the connector 2 and the wall panel 12 through the injection holes, thereby improving the connection between the two. The material selection and application method of the flexible caulking material can refer to the existing technology and will not be described in detail in this embodiment.

[0033] In this embodiment, the support plate 26 includes a mounting plate 261, a first connecting hole 262 arranged on the mounting plate 261 and matching the mounting hole 22, two extension plates 263 respectively arranged on both sides of the mounting plate 261 and extending to the upper connecting plate 24 and the lower connecting plate 25, and a horizontal plate 264 arranged at the end of the extension plate 263 and used to connect with the groove wall of the connecting groove 121; the extension plate 263 is arranged at an angle, and an arc-shaped protrusion 265 is provided on the surface of the extension plate 263 close to the upper connecting plate 24 / lower connecting plate 25; the support plate 26 is installed on the base plate 21 by means of bolts passing through the first connecting hole 262 and the mounting hole 22.

[0034] It is worth noting that the mounting plate 261 is directly mounted on the base plate 21 by bolts, and the mounting plate 261 can play the role of a gasket between the nut of the bolt and the base plate 21. The two extension plates 263 face opposite directions but have the same inclination angle, and the openings formed are from large to small, which will not interfere with the installation of the bolts. The inclined extension plate 263 has the ability to recover from deformation, so that the support plate 26 has a certain buffering function. Under the action of the extension plate, the cross plate 264 is tightly attached to the front groove side wall of the connecting groove 121, reducing the gap between the wall panel and the connecting piece, thereby strengthening the support of the wall panel 12. After the support plate 26 is fixed, it can block the plate seam outlet of the wall panel 12, preventing the flexible caulking filling material from flowing out into the gap between the two wall panels 12, reducing the loss of the flexible caulking filling material, and helping the flexible caulking filling material to fill in the required position to play a reinforcement and anti-cracking function.

[0035] In this embodiment, the connector 2 further includes a clamping plate 28 disposed in the gap between the bottom plate 21 and the upper connecting plate 24 / lower connecting plate 25, and tilted to clamp the wall panel 12. The clamping plate 28 includes an inclined plate 281 tilted on the bottom plate 21, and a protrusion 282 disposed on the surface of the inclined plate 281 at the end away from the bottom plate 21 and away from the upper connecting plate 24 / lower connecting plate 25. The clamping plate 28 with the above-mentioned structure also has a deformation recovery function. When the wall panel 12 is inserted into the connector, the clamping plate gradually increases the pressure on the back side of the wall panel 12 due to its tilted shape with a larger outer side and a smaller inner side, thereby pressing the wall panel 12 tightly and improving the tightness of the connection between the wall panel 12 and the connector.

[0036] To further reinforce the connector 2, the connector 2 further includes two ear plates 29 disposed on both sides of the base plate 21, which are different from the sides where the fixing plate 23 is mounted, and second connection holes 210 disposed on the ear plates 29. The second connection holes 210 are identical to the mounting holes 22 and are connected to the keel 11 via bolts.

[0037] It is understood that the lug plate 29 near the lower connecting plate can also be connected to the sides of the vertical keel and the through keel simultaneously via a long bolt to improve the tightness of the connection between the three. The keel 11 can also be filled with an insulation layer, equipped with gypsum board, etc. These structures are conventional options for those skilled in the art and will not be described in detail in this embodiment.

[0038] The advantages of the prefabricated wall panels provided in this embodiment over the prior art are that, while ensuring the anti-deformation effect, the amount of flexible caulking filling material used is greatly reduced, thereby avoiding problems such as uneven filling and uneven curing, which affect the fixing effect of the wall panels.

[0039] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
