Description

Technical Field

[0001] This invention belongs to the field of building technology and equipment, and relates to an environmentally friendly exterior wall insulation board anti-warping structure and construction method. Background Technology

[0002] Exterior wall insulation boards, also known as Horizon Building Exterior Wall Decoration Integrated Boards, are composite materials made of polymer mortar, fiberglass mesh, flame-retardant molded polystyrene foam board (EPS) or extruded polystyrene board (XPS). These exterior wall insulation boards integrate multiple functions and are manufactured in factories and bonded on-site. They are the preferred material for meeting current building energy-saving requirements and improving the insulation level of industrial and civil building exterior walls. They are also the first choice for energy-saving renovation of existing buildings. They are commonly used for high-rise exterior walls, indoor shopping malls, and industrial equipment, and have advantages such as low cost, good effect, corrosion resistance, and no pollution.

[0003] The problem of edge warping in exterior wall insulation boards has always been a challenge during construction and use. During construction, edge warping is usually caused by unevenness in the wall surface or the board itself. During use, edge warping is primarily due to the expansion and contraction of the material caused by temperature changes. Although exterior wall insulation boards generally have a relatively good coefficient of linear expansion and their volume change is usually small, it is still difficult to completely prevent deformation over a long period. Regardless of the cause of the warping, it can lead to the exterior wall insulation boards detaching.

[0004] Therefore, there is an urgent need for a new type of anti-warping structure and construction method for external wall insulation boards to solve the problem of warping edges. Summary of the Invention

[0005] To address the problem of warping edges in exterior wall insulation boards in the prior art, this invention provides an environmentally friendly anti-warping structure and construction method for exterior wall insulation boards.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0007] An environmentally friendly exterior wall insulation board anti-warping structure includes a positioning device, which includes an expansion tube and a cross plate. A core rod is inserted inside the expansion tube, and a threaded section is provided at the outer end of the core rod. A nut is threaded onto the threaded section, and the threaded section is detachably connected to the cross plate. A limit plate is provided on the outer side of the cross plate. The cross plate is used to engage with the gap between adjacent insulation boards, and the limit plate is used to abut against the outer surface of the insulation board.

[0008] Furthermore, the cross plate is detachably connected to the threaded section by screws.

[0009] Furthermore, a connecting section is provided at the end of the threaded section, and a threaded hole is provided in the connecting section. A screw seat is provided at the center of the cross plate, and the threaded shank of the screw passes through the screw seat. The end of the screw is threadedly connected to the threaded hole in the connecting section.

[0010] Furthermore, the screw seat has a countersunk hole on the outward side for accommodating the screw head.

[0011] Furthermore, a limiting sleeve is fitted on the outer side of the connecting section, and the two ends of the limiting sleeve abut against the outside of the screw seat and the nut, respectively.

[0012] Furthermore, the insulation board has arc-shaped clearance grooves at its four corners, and the limiting sleeve and screw seat are placed in the clearance grooves.

[0013] Furthermore, a cap is detachably connected to the port of the countersunk hole.

[0014] Furthermore, the end of the cap facing the screw is provided with a plug-in seat, which engages with the hexagonal hole of the head; a protruding ring is provided on the outer wall of the plug-in seat, and an annular groove is provided on the hexagonal hole of the head, with the protruding ring engaging with the annular groove.

[0015] Furthermore, a pair of notches are provided at the edge of the cover.

[0016] This invention discloses a construction method for an environmentally friendly exterior wall insulation board anti-warping structure based on the above-described technical solution. First, the insulation board is adhered to the outer surface of the wall, with a certain gap between adjacent insulation boards during the adhesion process. After adhesion, the clearance grooves on the corners of the four adjacent insulation boards form an installation hole. Holes are drilled into the wall along the installation hole, and then expansion tubes and core rods are inserted into the holes. Nuts are tightened using a socket wrench. During installation, the expansion tubes expand and become locked in the installation hole. Next, a cross plate is inserted between the gaps of adjacent insulation boards. Screws are then inserted into the screw holders, and an Allen wrench is used to force the screw ends into the threaded holes of the connecting section. After tightening the screws, the limiting plate presses firmly onto the outer surface of the insulation board, thereby preventing the exterior wall insulation board from warping and thus avoiding its detachment.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, after the insulation board is bonded, the clearance groove on the corner forms an installation hole. A hole is drilled into the wall along the installation hole, and the expansion tube and core rod are inserted into the hole. The nut is tightened, and the expansion tube expands and locks into the hole. Then, a screw is inserted into the screw seat and forced to the end into the threaded hole of the connecting section. The limiting plate is pressed against the outer surface of the insulation board, thereby achieving the function of preventing the outer wall insulation board from warping and thus preventing the outer wall insulation board from falling off.

[0019] 2. In this invention, the limiting sleeve is placed between the screw seat and the outer wall of the wall to limit the cross plate and the limiting plate, so as to prevent the screw from being tightened too much and causing the limiting plate to exert too much pressure on the insulation board.

[0020] 3. In this invention, the cover can shield the countersunk hole and the screws therein, and also can shield the rainwater and delay the corrosion of the connector.

[0021] In summary, this invention can prevent the exterior wall insulation board from warping, thereby avoiding the exterior wall insulation board from falling off. It has a simple structure, is easy to construct, and has high reliability. Attached Figure Description

A core rod 3 is inserted inside the expansion tube 2, and a threaded section 4 is provided at the outer end of the core rod 3 (the end that extends out of the wall after installation). A nut 5 is threaded onto the threaded section 4, and the threaded section 4 is detachably connected to the cross plate 8. A limiting plate 9 is provided on the outer side of the cross plate 8. The cross plate 8 is used to engage with the gap between adjacent insulation boards 19, and the limiting plate 9 is used to abut against the outer surface of the insulation board 19.

[0032] In this embodiment, the cross plate 8 is detachably connected to the threaded section 4 by a screw 7; further, a connecting section 6 is provided at the end of the threaded section 4, and a threaded hole is provided in the connecting section 6. A screw seat 10 is provided at the center of the cross plate 8, and the threaded shank of the screw 7 passes through the screw seat 10.

[0039] Example 2:

[0040] This invention discloses a construction method for an environmentally friendly exterior wall insulation board anti-warping structure based on Embodiment 1. The method is characterized by first bonding the insulation board 19 to the outer surface of the wall, ensuring a certain gap between adjacent insulation boards 19 during bonding. After bonding, the clearance grooves 20 on the corners of four adjacent insulation boards 19 form an installation hole. Holes are drilled into the wall along the installation hole, and then expansion tubes 2 and core rods 3 are inserted into the holes. Nuts 5 are tightened using a socket wrench. During installation, expansion tubes 2 expand and become stuck in the installation hole. Then, a cross plate 8 is inserted between the gaps of adjacent insulation boards 19. Screws 7 are then inserted into screw seats 10. An internal hex wrench is used to tighten the screws 7, forcing their ends into the threaded holes of the connecting section 6. After tightening the screws 7, the limiting plate 9 presses against the outer surface of the insulation board 19, thereby preventing the exterior wall insulation board from warping and thus avoiding its detachment.
