Description

An auxiliary connecting fastener for prefabricated interior wall panels and its connection method Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary connecting fastener for prefabricated interior wall panels and its connection method. Background Technology

[0002] With the development of the construction industry, the country is paying more and more attention to the concept of low carbon. Prefabricated buildings provide a flexible construction concept for urbanization. Using prefabricated wall panels to build prefabricated buildings can improve the degree of mechanization and shorten the construction cycle.

[0003] In existing technology, when prefabricated interior wall panels are spliced, a protrusion is set at one end of the wall panel and a connecting groove is set at the other end. The protrusion is inserted into the connecting groove, and then the connection between the two wall panels is fixed with steel bars. However, after the two prefabricated interior walls are spliced ​​together with the protrusion and connecting groove, there is no fixing structure at this time, which causes the two prefabricated walls to slide relative to each other and gaps to appear. This affects the firmness of the steel bar connection and the quality of the spliced ​​two prefabricated walls. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary connecting fastener and a connecting method for prefabricated interior wall panels, so as to solve the problems mentioned in the background art.

The chamfers are triangular prism structures with two chamfers, which are symmetrically distributed about the center of the short side of the top surface of the filling plate.

[0011] A method for connecting auxiliary connecting fasteners of precast interior wall panels includes the following steps: Step 1: Pre-assembly, where a splicing block of one precast interior wall panel is joined to a splicing groove of another precast interior wall panel. During this process, the guide groove slides along the guide strip, and the filler plate is inserted into the joining groove, thus achieving the assembly of the two precast interior wall panels.

The chamfer 16 is a triangular prism structure, and there are two chamfers 16. The two chamfers 16 are aligned with the center of the short side of the top surface of the filling plate 15. The assembly is described as follows: A splicing block 6 of one precast interior wall panel 1 is joined to a splicing groove 2 of another precast interior wall panel 1. During this process, the guide groove 5 slides along the guide strip 4, and the filling plate 15 is inserted into the joining groove 14, thus assembling the two precast interior wall panels 1. However, at this time, there is no fixing structure between the two precast interior wall panels 1. A recessed groove 7 is formed on the surface of the splicing block 6, and a connecting screw 8 is screwed to the side wall of the recessed groove 7. The recessed groove 7 has a trapezoidal column structure, and the height of the recessed groove 7 is less than the height of the splicing block 6. The limiting plate 9 has a trapezoidal ring structure, and the sealing plate 10 has a trapezoidal plate structure. The sealing plate 10 is positioned within the limiting plate 9. Directly above, using a wrench, insert it into the recessed groove 7 and tighten the three connecting screws 8 inside the recessed groove 7 respectively. During the tightening process, the rod of the connecting screw 8 is inserted into and screwed into the inside of the sleeve 3, so that the splicing block 6 is fixed in the splicing groove 2 and no longer slips out. The surface of the recessed groove 7 is fixedly connected to the limiting plate 9. A sealing plate 10 is inserted into the opening of the recessed groove 7. The sealing plate 10 is inserted into the opening of the recessed groove 7 and overlaps the limiting plate 9.

Multiple rubber sealing sheets 13 are provided, and they are assembled to form a circular plate structure to seal the pouring port 12. To prevent the connecting screw 8 from loosening, a pouring pipe is inserted into the pouring port 12. When the pouring pipe is inserted, it pushes the multiple rubber sealing sheets 13 downwards into the recessed groove 7. After pouring concrete, the pouring pipe is pulled out of the pouring port 12. At this time, the multiple rubber sealing sheets 13 rebound and reset, covering the opening of the pouring port 12. After the concrete hardens, this prevents the connecting screw 8 from loosening.

[0017] A connection method for auxiliary connecting fasteners of prefabricated interior wall panels includes the following steps: Step 1: Pre-assembly, where the splicing block 6 of one prefabricated interior wall panel 1 is mated to the splicing groove 2 of another prefabricated interior wall panel 1. During this process, the guide groove 5 slides along the guide strip 4, and the filling plate 15 is inserted into the mating groove 14, thus achieving the assembly of two prefabricated interior wall panels 1. However, at this time, there is no fixing structure between the two prefabricated interior wall panels 1. Step 2: Reinforcement connection, using a wrench inserted into the recessed groove 7, the three connecting screws 8 inside the recessed groove 7 are tightened respectively. During the tightening of the connecting screws 8, the rod body of the connecting screw 8 is inserted into and screwed into the inside of the sleeve 3. Thus, the splicing block 6 is fixed in the splicing groove 2 and will not slip out; Step 3: Sealing, insert the sealing plate 10 into the opening of the recessed groove 7, the sealing plate 10 overlaps the limiting plate 9, and the flexible sealing strip 11 is squeezed between the sealing plate 10 and the recessed groove 7 to play a damping and sealing role; Step 4: Pouring, in order to prevent the connecting screw 8 from loosening, insert the pouring pipe into the pouring port 12. When the pouring pipe is inserted, multiple rubber sealing pieces 13 are pushed downward. After pouring concrete into the recessed groove 7, the pouring pipe is pulled out from the pouring port 12. At this time, multiple rubber sealing pieces 13 rebound and reset to cover the opening of the pouring port 12. After the concrete solidifies, the connecting screw 8 is prevented from loosening.

[0018] Working principle: In actual use, the splicing block 6 of one prefabricated interior wall panel 1 is joined to the splicing groove 2 of another prefabricated interior wall panel 1. During this process, the guide groove 5 slides along the guide strip 4, and the filling plate 15 is inserted into the joining groove 14, thus assembling the two prefabricated interior wall panels 1. However, at this time, there is no fixing structure between the two prefabricated interior wall panels 1. With the help of a wrench, the three connecting screws 8 inside the recessed groove 7 are tightened respectively. During the tightening of the connecting screws 8, the rod body of the connecting screw 8 is inserted into and screwed into the inside of the sleeve 3, thus fixing the splicing block 6. The sealing plate 10 is inserted into the opening of the recessed groove 7 and no longer slides out in the splicing groove 2. The sealing plate 10 overlaps the limiting plate 9, and the flexible sealing strip 11 is squeezed between the sealing plate 10 and the recessed groove 7 to play a damping and sealing role. In order to prevent the connecting screw 8 from loosening, the pouring pipe is inserted into the pouring port 12. When the pouring pipe is inserted, multiple rubber sealing pieces 13 are pushed downward. After pouring concrete into the recessed groove 7, the pouring pipe is pulled out from the pouring port 12. At this time, multiple rubber sealing pieces 13 rebound and reset to cover the opening of the pouring port 12. After the concrete is cured, the connecting screw 8 is prevented from loosening.
