DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1 , Figure 2 As shown, an assembled waterproof exterior wall structure includes a light steel frame 1, a plurality of wall panels 2 and a locking member 3.

[0017] like Figure 1 , Figure 2 As shown, the light steel frame 1 is arranged in a rectangular shape, and a plurality of vertical beams 11 are vertically arranged in the light steel frame 1, and the vertical beams 11 divide the light steel frame 1 into a plurality of rectangular installation spaces 12. A plurality of wall panels 2 are respectively embedded in each installation space 12 of the light steel frame 1, and the locking member 3 is used to fix the wall panel 2 in the installation space 12.

[0018] When constructing the exterior wall structure, first fix the light steel frame 1 at the installation position, then embed each wall panel 2 in each installation space 12, and then fix them with the locking piece 3, so that the exterior wall structure can be constructed quickly and conveniently.

[0019] like Figure 3 As shown, the wall panel 2 includes a keel support 21 , a glass fiber layer 22 , a European pine board 23 , a moisture-proof cloth 24 , a flame-retardant polystyrene board 25 , an outer panel 26 and an inner panel 27 .

[0020] like Figure 3 As shown, the keel bracket 21 is double-layered and has a gap formed inside, and the glass fiber layer 22 is filled in the keel bracket 21. The European pine board 23 is covered on both sides of the keel bracket 21, the moisture-proof cloth 24 is glued to the surface of the outer layer of the European pine board 23, and the flame-retardant polystyrene board 25 is arranged on the surface of the moisture-proof cloth 24.

[0021] like Figure 3 As shown, the outer panel 26 and the inner panel 27 are both made of PVC material, the outer panel 26 is arranged on the surface of the flame retardant polystyrene board 25, and the inner panel 27 is arranged on the surface of the inner layer of the European pine board 23. The keel bracket 21 is provided with a ring 28 extending to both sides to wrap around the outer panel 26 and the panel.

[0022] Therefore, by providing a lightweight wall panel 2, the dead weight of the wall panel 2 is reduced while ensuring the structural strength of the wall panel 2, and a quick-connect fixing method is used for installation, making the handling and assembly process easier and more convenient, thereby improving construction efficiency.

[0023] like Figure 3 As shown, the European pine board 23 includes a middle board 231 and a pair of side boards 232. A dovetail block 233 is transversely arranged on the inner side of the middle board 231, and a groove 234 for the dovetail block 233 to be embedded in and a dovetail groove 235 communicating with the groove 234 and for the dovetail block 233 to be slidably embedded in are horizontally arranged on the keel bracket 21. A row of hooks 236 are arranged on the back side of the side board 232, and a hook hole 237 is arranged on the keel bracket 21 for the hook 236 to pass through.

[0024] like Figure 3 As shown, a plurality of fixing hooks 261 are horizontally arranged on the inner sides of the outer panel 26 and the inner panel 27, and fixing holes 262 for the fixing hooks 261 to pass through and hook are arranged on the OSB board 23.

[0025] like Figure 3 As shown, the outer panel 26 and the inner panel 27 are all provided with a pressing ring 263 which presses the surface of the enveloping ring 28 . The inner wall of the pressing ring 263 is provided with a circle of clamping ring 264 . The enveloping ring 28 is provided with a clamping groove 265 for the clamping ring 264 to be embedded.

[0026] When the wall panel 2 is produced and processed, the glass fiber is first filled into the keel bracket 21, and then the middle panel 231 is taken out and attached to the keel bracket 21, so that the dovetail block 233 on the middle panel 231 is embedded in the groove 234 on the keel bracket 21, and then the middle panel 231 is pushed to slide horizontally, so that the dovetail block 233 is embedded in the dovetail groove 235, so as to achieve the clamping and limiting of the middle panel 231. Then the side panel 232 is taken out, so that the side panel 232 is attached to the keel bracket 21, and then the side panel 232 is knocked, so that the hook 236 on the side panel 232 passes through the clamping hole 237 on the keel bracket 21, so as to achieve the fixation of the side panel 232, thereby achieving the clamping and fixing installation of the entire European pine board 23.

[0027] Then, the moisture-proof cloth 24 is attached to the surface of the outer layer of the European pine board 23, and then the flame-retardant polystyrene board 25 is placed on the surface of the moisture-proof cloth 24, and the enveloping ring 28 is used to surround and limit the position. Then, the outer panel 26 of the outer layer is taken out, so that the outer panel 26 is attached to the surface of the flame-retardant polystyrene board 25 and is located in the enveloping ring 28. Then, the outer panel 26 is pressed or knocked, so that the fixing hook 261 on the outer surface passes through the reserved holes on the flame-retardant polystyrene board 25 and the moisture-proof cloth 24, and then the fixing hole 262 on the outer layer of the European pine board 23 is penetrated to achieve the installation and fixation of the outer panel 26, and at the same time, the flame-retardant polystyrene board 25 is pressed and fixed, and the stability of the connection position is ensured.

[0028] Then take out the inner panel 27 of the inner layer, make the inner panel 27 fit the inner layer OSB board 23, and then press or knock the inner panel 27 so that the fixing hooks 261 on the inner surface pass through the fixing holes 262 on the inner layer OSB board 23 to achieve the installation and fixation of the inner panel 27.

[0029] And during the installation process of the outer panel 26 and the inner panel 27, the clamping ring 264 on the inner side of the pressure ring 263 on the outer panel 26 and the inner panel 27 will automatically embed into the clamping groove 265 on the ring 28, and form a seal at the connection position, thereby improving the sealing and waterproof performance of the entire wall panel 2, ensuring that the wall panel 2 will not be deformed by moisture, and preventing the water from the outside and the inside from communicating with each other, thereby ensuring the waterproof performance of the entire exterior wall structure.

[0030] Therefore, by adopting the full-clamping fixing method, the connection and fixation between the various layers of the entire wall panel 2 is achieved, and at the same time, the assembly process between the various layers of the structure is made more convenient, thereby effectively improving the production efficiency of the entire wall panel 2 itself.

[0031] like Figure 4 As shown, the locking member 3 includes a locking ring 31 , a locking strip 32 and a locking strip 33 .

[0032] like Figure 4As shown, the locking ring 31 is arranged on the outer wall of the outer enveloping ring 28 and is used to compress the outer side of the light steel frame 1. A circle of sealing rings 34 is arranged on the inner wall of the locking ring 31, and sealing grooves 35 for the sealing rings 34 to be embedded are arranged on the light steel frame 1 and the vertical beam 11, so as to increase the sealing and waterproof performance of the connection position between the two.

[0033] like Figure 4 As shown, the locking strip 32 is vertically arranged on the outside of the vertical beam 11 and located between a pair of adjacent inner circles 28. The clamping strip 33 is vertically and tilted outwardly arranged on both sides of the locking strip 32, and the outer wall of the circle 28 is provided with a locking groove 36 for the clamping strip 33 to be embedded.

[0034] like Figure 4 As shown, a plurality of locking hooks 37 are horizontally and spaced apart from each other on the inner side of the locking strip 32 , and locking holes 38 for the locking hooks 37 to pass through are provided on the vertical beam 11 .

[0035] When the wall panel 2 and the light steel frame 1 need to be connected and fixed, the wall panel 2 is embedded in the installation space 12 on the light steel frame 1. At this time, the wall panel 2 is pushed so that the locking ring 31 on the ring 28 presses the outer wall of the light steel frame 1. At the same time, the sealing ring 34 on the locking ring 31 is embedded in the sealing groove 35 on the light steel frame 1, thereby increasing the sealing and waterproof performance of the connection position.

[0036] Then, the locking strip 32 is placed between adjacent wall panels 2, so that the locking strip 32 is located between the collars 28, and then the locking strip 32 is knocked or hammered to move inward. At this time, the clamping strips 33 on both sides of the locking strip 32 are automatically embedded in the locking grooves 36 on the collar 28, so that the locking strip 32 and the wall panels 2 are clamped and fixed.

[0037] At the same time, the locking hook 37 on the locking strip 32 will automatically penetrate the locking hole 38 on the vertical beam 11, thereby further fixing the locking strip 32, increasing the stability of the locking strip 32, thereby achieving stable installation of the entire wall panel 2 and improving the structural strength of the connection position.

[0038] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
