Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated building technology, and in particular to a waterproof sealing device for prefabricated buildings. 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, parking spaces, flower beds, and isolation piers) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods.
[0003] Prefabricated waterproof windows are wall panels with windows. The window frame is one of the main structures of the window. Currently, the window frame is installed by drilling holes in the window frame and the concrete wall of the window, and then inserting expansion bolts into the holes to fix the window frame directly. In this fixing method, there is no waterproof sealing device on the side of the window frame facing the inside of the room. Rainwater can easily flow into the room from the gap between the window frame and the window, and the waterproof effect is not good enough. Utility Model Content
[0004] The purpose of this utility model is to provide a prefabricated building waterproof sealing device to solve at least one of the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building waterproof sealing device, comprising a concrete wall, a window, a sealing component, and a fixing component. The concrete wall has a rectangular opening in the middle, with the opening on the outer side of the installation window being larger than the inner opening. A platform extends from the center of the installation window inwards to form a platform. Two identical slots are provided around the top and bottom of the platform. The window is inserted into the installation window through the larger opening. The sealing component includes a rectangular fixing plate and two rectangular blocks. The rectangular fixing plate is fixedly connected to the rear side of the window and matches the platform. The two rectangular blocks are fixedly fixed to the rear side of the rectangular fixing plate near the top and bottom, and the two rectangular blocks match the corresponding slots. The fixing component is fixedly connected to the front side of the window near the edge.
[0006] Preferably, bolt holes are provided at equal intervals around the perimeter of the installation window near the opening, and a rectangular fixing frame is fixedly connected around the perimeter of the front side of the window near the edge. The fixing frame is fixed to the inner wall of the installation window by screwing expansion screws into the corresponding bolt holes around the perimeter of the inner wall of the rectangular fixing frame near the outer edge.
[0007] Preferably, the four sides of the concrete wall are fixedly connected with first extension steel bars at equal intervals near both ends, and a second extension steel bar is fixedly connected between the two rows of first extension steel bars on each side of the concrete wall.
[0008] Preferably, a sealing strip is provided on the circumference gap formed between the window and the installation window after the window is inserted.
[0009] Preferably, the slot and the rectangular card block engage to form a tongue and groove joint.
[0010] The beneficial effects of this utility model are as follows:
[0011] The two tongue-and-groove joints formed by the interlocking of the slot and the rectangular block make the gap path between the slot and the rectangular block longer, increasing the path length and difficulty of water penetration. This makes it difficult for rainwater to directly enter the building through the joint, effectively reducing the phenomenon that rainwater can easily flow into the room from the gap between the window frame and the window, greatly improving the waterproof effect and making it highly practical.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides, for example Figure 1-6 The prefabricated building waterproof sealing device shown includes a concrete wall 4, a window 1, a sealing component, and a fixing component. The concrete wall 4 has a rectangular opening installation window 8 in the middle, and the opening of the installation window 8 on the outside of the concrete wall 4 is larger than the opening on the inside. A platform 11 is formed by extending around the middle of the installation window 8. Two identical slots 9 are provided around the platform 11 near the top and bottom. The window 1 is inserted into the installation window 8 through the larger opening. The sealing component includes a rectangular fixing plate 13 and two rectangular blocks 12. The rectangular fixing plate 13 is fixedly connected to the rear side of the window 1 and matches the platform 11. The two rectangular blocks 12 are fixedly fixed to the rear side of the rectangular fixing plate 13 near the top and bottom and match the corresponding slots 9. The fixing component is fixedly connected to the front side of the window 1 near the edge.
[0021] Construction workers installed the first extension steel bar 5 and the second extension steel bar 6 on the already poured wall, inserted the extension steel bars into the steel bar insertion holes on the poured wall, and completed the pouring to fix the concrete wall 4. Then, polyurethane foam was injected around the platform 11. The window 1 was then inserted into the installation window 8 along the side with the larger opening, so that the rectangular fixing plate 13 was tightly attached to the platform 11. At this time, the two rectangular clips 12 were respectively inserted into the corresponding slots 9. The polyurethane foam was squeezed to fill and seal the gaps between the rectangular fixing plate 13 and the platform 11 and between the rectangular clips 12 and the slots 9. The workers then screwed the expansion bolts 3 into the bolt holes 10 to fix the fixing frame 2 to the inner wall of the installation window 8, thereby further fixing the window 1. Finally, glue was applied to the sealing strip 7 and the sealing strip 7 was stuck to the gap at the connection between the window 1 and the installation window 8 to further waterproof and seal the connection between the window 1 and the installation window 8.
[0022] Bolt holes 10 are provided at equal intervals around the perimeter of the installation window 8 near the opening. A rectangular fixing frame 2 is fixedly connected around the perimeter of the front side of the window 1 near the edge. The perimeter of the inner wall of the rectangular fixing frame 2 near the outer edge is fixed to the inner wall of the installation window 8 by screwing expansion bolts 3 into the corresponding bolt holes 10.
[0023] Construction workers screw the expansion bolts 3 into the bolt holes 10 on the installation window 8 through the mounting holes on the rectangular fixing frame 2. This fixes the rectangular fixing frame 2 to the side wall of the installation window 8, thereby securing the window 1 and improving its stability.
[0024] The four sides of the concrete wall 4 are fixedly connected with first extension steel bars 5 at equal intervals near both ends. On each side of the concrete wall 4, a second extension steel bar 6 is fixedly connected between the two rows of first extension steel bars 5.
[0025] Construction workers fix the concrete wall 4 by installing the first extension steel bar 5 and the second extension steel bar 6 on the already poured wall, inserting the extension steel bars into the corresponding steel bar insertion holes on the poured wall and pouring the concrete.
[0026] A sealing strip 7 is provided on the circumference gap formed between the form 1 and the installation window 8 after the form 1 is inserted into the installation window 8.
[0027] The sealing strip 7 is made of rubber. Rubber has good sealing properties. After the sealing strip 7 is glued to the gap between the installation window 8 and the installation window 8, it can effectively prevent rainwater from seeping into the gap.
[0028] After the slot 9 and the rectangular card block 12 engage, they form a tongue and groove joint.
[0029] The special structure of the tongue and groove joint creates a maze-like structure at the joint, increasing the path length and difficulty of water infiltration, making it difficult for rainwater to directly enter the building through the joint, effectively reducing the occurrence of leakage. The two tongue and groove joints formed by the slot (9) and the rectangular slot (12) can effectively reduce the infiltration of rainwater from outside the window into the house.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
