An energy-saving and environmentally friendly prefabricated building wall structure

Abstract

An energy-saving and environmentally friendly prefabricated building wall structure includes a prefabricated wall and through holes. The surface of the prefabricated wall has multiple through holes, and the inner wall of the prefabricated wall has grooves. The inner wall of the grooves abuts against connecting caps, and the outer wall of the connecting caps has round holes. The connecting caps, placed inside the grooves, also insert into the ends of external reinforcing bars. The upper end of the connecting caps also needs to be inserted into the reinforcing bars in the prefabricated wall. The round holes on the side of the connecting caps are used to weld the external reinforcing bars and the reinforcing bars in the prefabricated wall together, thus fixing the external reinforcing bars and the reinforcing bars in the prefabricated wall to the connecting caps. The outer wall of the iron ring on the prefabricated strip abuts against the outer wall of the connecting cap. A cement layer is applied to the outer surfaces of the prefabricated strip and the prefabricated wall for sealing, achieving complete fixation between the welding method and the external reinforcing bars and the prefabricated wall, thus improving the firmness of the prefabricated wall installation.

Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to an energy-saving and environmentally friendly prefabricated building wall structure. Background Technology

[0002] Prefabricated building wall structure refers to transferring 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, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] For example, a prefabricated building wall structure with publication number "CN222614611U" solves the problem of existing energy-saving prefabricated building wall structures where multiple pre-embedded steel bar connection holes need to be individually grouted, which is cumbersome. It injects grout into the grouting connection cavity through the grouting port, and then seals the overflow port filled with grout one by one with sliding baffles. After providing stable support for the prefabricated shear wall, the external wall insulation board is installed on the outside of the prefabricated shear wall by aligning the fixing bolts with the through-wall sleeve. Considering the existing prefabricated building wall structure, grouting is required for the steel bar connection holes. However, the water-based grout has a solidifying property, and it cannot be guaranteed that all the cement grout will flow from the connection hole into the connection cavity and out through the overflow port, thus failing to completely fix the external steel bars to the prefabricated wall. This results in low-quality prefabricated wall installation. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing an energy-saving and environmentally friendly prefabricated building wall structure. It adopts a welding method to completely fix the external steel bars to the prefabricated wall, thereby improving the firmness of the prefabricated wall installation.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] Design an energy-saving and environmentally friendly prefabricated building wall structure, including a prefabricated wall and through holes. The surface of the prefabricated wall is processed with multiple through holes, and the inner wall of the prefabricated wall is processed with grooves. The inner wall of the grooves abuts against a connecting cap, and the outer wall of the connecting cap is processed with a round hole. The inner wall of the prefabricated box is connected with a fixing mechanism.

[0007] Further improvements include a precast strip, the outer wall of which is movably connected to the precast box body, the front end of which is fixedly connected to an iron ring, and the other end of which is machined with a placement groove.

[0008] Further improvements include abutting the outside of the iron ring against the connecting cap, and a prefabricated insulation mechanism connected to the outside of the circular hole.

[0009] In a further improvement, the prefabricated insulation mechanism includes a round rod, the outer wall of which abuts against a round hole, the outer wall of which is fixedly connected to a fixing strip, and the outer wall of which is fixedly connected to an insulation board.

[0010] Further improvements include a fixed connection between the outer wall of the insulation board and the cement layer, and a fixed connection between the outer wall of the cement layer and the precast wall.

[0011] To further improve the design, a square groove is machined at the lower end of the precast wall.

[0012] Further improvements include ensuring that the protrusions on the outer wall of the insulation board abut against the placement groove.

[0013] The beneficial effects of this utility model are as follows: In this utility model, the connecting cap placed inside the groove is also inserted into the end of the external reinforcing bar. The upper end of the connecting cap and the reinforcing bar in the precast wall also need to be inserted. The round hole on the side end of the connecting cap is used to weld the external reinforcing bar and the reinforcing bar in the precast wall together, so that the external reinforcing bar and the reinforcing bar in the precast wall are mutually fixed with the connecting cap. The outer wall of the iron ring on the precast strip is pressed against the outer wall of the connecting cap. The cement layer is applied to the outer surface of the precast strip and the precast wall for sealing, realizing the welding method and the complete fixation between the external reinforcing bar and the precast wall, improving the firmness of the precast wall installation.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Example 1:

[0023] See attached document Figure 1-6 In this embodiment, an energy-saving and environmentally friendly prefabricated building wall structure includes a prefabricated wall 1 and through holes 2. The surface of the prefabricated wall 1 is processed with multiple through holes, and the inner wall of the prefabricated wall 1 is processed with grooves 3. The inner wall of the grooves 3 abuts against the connecting caps 4. The outer wall of the connecting caps 4 is processed with round holes 5, and the inner wall of the prefabricated box 1 is connected with a fixing mechanism 6.

[0024] The fixing mechanism 6 includes a precast strip 601, which is mutually fixed to the connecting cap 4 by the external reinforcing bars and the reinforcing bars in the precast wall 1. The connecting cap 4 is limited and fixed by the iron ring 602 on the precast strip 601. The outer wall of the precast strip 601 is movably connected to the precast box 1. The front end of the precast strip 601 is fixedly connected to the iron ring 602. The other end of the precast strip 601 is processed with a placement groove 603.

[0025] The connecting cap 4 is placed inside the groove 3 and is also inserted into the end of the external reinforcing bar. The upper end of the connecting cap 4 and the reinforcing bar in the precast wall 1 also need to be inserted. The external reinforcing bar and the reinforcing bar in the precast wall 1 are welded together using the round hole 5 on the side of the connecting cap 4, so that the external reinforcing bar and the reinforcing bar in the precast wall 1 are fixed to the connecting cap 4. The outer wall of the iron ring 602 on the precast strip 601 is pressed against the outer wall of the connecting cap 4. The cement layer 8 is applied to the outer surface of the precast strip 601 and the precast wall 1 for sealing, so as to achieve complete fixation between the welding method and the external reinforcing bar and the precast wall, and improve the firmness of the precast wall installation.

[0026] The outer side of the iron ring 602 abuts against the connecting cap 4, and the outer side of the round hole 5 is connected to the prefabricated insulation mechanism 7. By inserting the round rod 701 on the fixing strip 702 into the through hole 2, the insulation board 703 of the same size on the fixing strip 702 is laid flat on the surface of the prefabricated wall 1, so that the prefabricated wall 1 has the effect of insulation. The prefabricated insulation mechanism 7 includes the round rod 701, the outer wall of the round rod 701 abuts against the round hole 5, the outer wall of the round rod 701 is fixedly connected to the fixing strip 702, and the outer wall of the fixing strip 702 is fixedly connected to the insulation board 703.

[0027] The outer wall of the insulation board 703 is fixedly connected to the cement layer 8, the outer wall of the cement layer 8 is fixedly connected to the precast wall 1, the lower end of the precast wall 1 is processed with a square groove 9, and the outer wall of the insulation board 703 is processed with protrusions that abut against the placement groove 603.

[0028] Working principle:

[0029] External reinforcing bars are inserted into the groove 3 at the lower end of the precast wall 1. Simultaneously, when a connecting cap 4 is placed inside the groove 3 of the precast wall 1, the reinforcing bars in the precast wall 1 are inserted into the upper end of the connecting cap 4. When the precast wall 1 is lifted using external equipment, the ends of the external reinforcing bars are inserted into the connecting cap 4 at the lower end of the precast wall 1. The external reinforcing bars and the reinforcing bars in the precast wall 1 are welded together using the round hole 5 on the side of the connecting cap 4, thus fixing the external reinforcing bars and the reinforcing bars in the precast wall 1 to the connecting cap 4, allowing the precast wall 1 to be placed vertically on the ground. At this point, the precast strip 601 is pushed into the groove 3, causing the outer iron ring 602 on the precast strip 601 to... The wall is pressed tightly against the outer wall of the connecting cap 4, and a cement layer 8 is applied to the outer surface of the precast strip 601 and the precast wall 1. The round rod 701 on the fixing strip 702 is inserted into the through hole 2. The fixing strip 702 can lay the insulation board 703 flat on the surface of the precast wall 1. After the cement layer 8 solidifies, the fixing strip 702 and the insulation board 703 are attached and fixed to the outer wall of the precast wall 1. Cement is applied to the square groove 9 at the lower end of the precast wall 1 to reinforce and seal the gaps, ensuring that the precast wall 1 is installed firmly. The precast wall 1 and the insulation board 703 can be assembled in advance, reducing on-site processing and improving the energy saving and environmental protection of the construction.
