Description

Technical Field

[0001] The invention belongs to the technical field of building walls, and in particular relates to a connection component, a wall with the connection component and a construction process thereof. Background Art

[0002] As the exterior wall of the prefabricated building, the insulation exterior wall usually includes the exterior wallboard (the exterior layer of the insulation exterior wall), the insulation layer and the interior wallboard (the interior layer of the insulation exterior wall) from the outside to the inside. The insulation layer is usually composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS) and other materials. In the prior art, the construction method of the insulation layer is mostly to bond the exterior wallboard and the interior wallboard with adhesive at the construction site, or to directly apply the insulation layer prepolymer on the exterior wallboard for on-site molding. The adhesive is easy to age, and the connection strength between the insulation layer and the exterior wallboard and the interior wallboard is reduced under the erosion of the external environment, and it is easy to cause interlayer shedding, which in turn affects the stability of the building exterior wall.

[0003] In order to solve this problem, the invention patent application with application number CN201811198350.8 "A thermal insulation exterior wall and its construction process" (application publication number CN109469220A) discloses a thermal insulation exterior wall and its construction process, including a base wall layer, a thermal insulation layer and a decorative layer, a thermal insulation layer is arranged outside the base wall layer, a decorative layer is arranged outside the thermal insulation layer, a card slot is arranged on the base wall layer, a card block is arranged on the thermal insulation layer, the card block is adapted to the position of the card slot, a reinforcing steel nail is arranged between the base wall layer and the thermal insulation layer, and an expansion bolt is arranged between the thermal insulation layer and the decorative layer; the application improves the fixing stability between the high base wall layer and the thermal insulation layer by engaging the reinforcing steel nail and the card block arranged between the base wall layer and the thermal insulation layer with the card slot. However, the thermal insulation board in the technical solution still needs to be bonded to the base wall layer with adhesive glue. According to the process disclosed in the application, the bonding process has high requirements, and the construction process of the reinforcing steel nail and the expansion bolt is complicated, which will waste a lot of time and reduce efficiency. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a connection assembly capable of effectively connecting the exterior wall panel with the insulation layer and the interior wall panel in view of the current status of the prior art, so as to be applicable to the wall of the prefabricated building and its construction process.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] The connecting body is used to penetrate and be arranged in the thermal insulation layer, and its two ends located on both sides of the thermal insulation layer are respectively used to be buried in the outer wall board and the inner wall board of the thermal insulation outer wall;

[0008] A positioning assembly is installed at least at one end of the connection body, and the positioning assembly includes at least two positioning rods, one end of the positioning rod is connected to the connection body, and the other end is used to connect to the stress reinforcement of the outer wall board or the inner wall board of the thermal insulation outer wall;

[0009] When the positioning components are installed at both ends of the connection body, the positioning component connected to at least one end of the connection body is detachably connected to the connection body.

[0010] In the above scheme, the positioning components are respectively installed at both ends of the connection body, and the positioning components and both ends of the connection body can be detachably connected. Or, the positioning components are respectively installed at both ends of the connection body, the positioning component installed at one end of the connection body is fixedly connected thereto, and the positioning component installed at the other end of the connection body is detachably connected thereto. Or, the positioning component is only installed at one end of the connection body, and the positioning component is fixedly connected or detachably connected to the connection body. The fixed connection between the positioning component and the connection body can be hinged, ball-jointed or welded. The detachable connection between the positioning component and the connection body can be pivoted, suspended or hooked.

[0011] With the above scheme, the connection component passes through the insulation layer and its two ends are fixedly connected to the outer wall panel or the inner wall panel through the connection body, connecting the three layers of the wall into a whole, preventing the interlayer shedding phenomenon, improving the connection strength between the insulation layer and the outer wall panel and the inner wall panel, and thus improving the stability of the building's exterior wall. The main function of the positioning component is to fix the position of the connection body on the wall, thereby facilitating the subsequent installation of the insulation layer. The second function of the positioning component is to connect the connection component to the force-bearing reinforcement of the outer wall panel or the inner wall panel, further improving the connection strength between the connection component and the outer wall panel or the inner wall panel, thereby improving the interlayer connection strength of the wall. The positioning component includes at least two positioning rods, which play a positioning role and are used to fix the connection body in a specific position so that it is not easy to move, thereby facilitating the subsequent installation process, and at the same time, it can also improve the connection strength between the connection component and the outer wall panel or the inner wall panel.

[0012] Furthermore, the positioning rod includes a rod body, and a first hook is provided at one end of the rod body for hooking with the stress-bearing reinforcement of the outer wall panel or the inner wall panel of the thermal insulation outer wall.

[0013] Furthermore, a positioning portion is provided on the connecting body, and a second hook is provided at one end of the rod body, and the second hook is hooked with the positioning portion.

[0014] By adopting the above scheme, the hook-up method is easy to install, the process is simple, the workers' labor time is saved, and the efficiency is improved.

[0015] Furthermore, the positioning parts are evenly arranged along the circumference of the two ends of the connecting body, and the positioning rods are hooked with the positioning parts in a one-to-one correspondence.

[0016] The above scheme is adopted to strengthen the positioning effect, and is used to fix the connection body at a specific position and prevent it from moving, thereby facilitating the subsequent installation process, and at the same time further improving the connection strength between the connection component and the exterior wall panel or the interior wall panel.

[0017] Further, the positioning portion includes a hanging ear protruding outward from the connecting body;

[0018] Or, the positioning portion includes a groove dug into the connecting body and a horizontal piece arranged in the groove;

[0021] With the above structure, the hollow cylindrical structure is convenient for hooking, and can reduce the deadweight of the connection assembly, facilitate installation, and reduce the labor intensity of workers; in addition, concrete can be poured inside the hollow cylinder, thereby improving the integrity and connection strength between the layers of the wall. The structure of the mounting hole and the positioning hole makes it difficult for the positioning rod to fall out of the positioning part, thereby improving the connection reliability between the positioning rod and the positioning part.

[0022] Furthermore, the transition section is an arc-shaped transition section or an acute-angle transition section.

[0023] Furthermore, the mounting hole is a waist-shaped hole, the length of which is greater than the maximum width of the second hook-shaped body, and the width of which is greater than the minimum width of the second hook-shaped body; the positioning hole is a circular hole or a polygonal hole adapted to the cross-section of the hook portion of the second hook-shaped body.

[0024] With the above structure, the waist-shaped hole can make the second hook-shaped body as easy to enter the installation hole as possible, and it is difficult to get out of the installation hole after rotating a certain angle, thereby improving the connection reliability between the positioning rod and the positioning part. The positioning hole is adapted to the cross-sectional shape of the hook part of the second hook-shaped body, making it difficult for the positioning rod to get out, thereby further improving the connection reliability between the positioning rod and the positioning part.

[0025] The second technical problem to be solved by the present invention is to provide a wall with the above-mentioned connection assembly in view of the current status of the prior art, in which the outer wall panels, insulation layer and inner wall panels are firmly connected and not easy to separate, the operation is simple and easy to install, and the labor intensity of on-site workers is reduced.

The wall is prefabricated in the workshop and does not need to be installed twice at the construction site, reducing the labor intensity of workers at the construction site.

[0033] The third technical problem to be solved by the present invention is to provide a construction process for the above-mentioned wall in view of the current status of the prior art, which is simple in process, saves workers' labor time and improves efficiency.
