Description

Technical Field

[0001] This utility model relates to the field of thermal insulation wall panel technology, and in particular to a connector for external wall insulation panels. Background Technology

[0002] The structure of external wall insulation boards consists of a leveling layer, an insulation layer, a crack-resistant layer, and a finishing layer attached to the exterior wall of a building. Generally, the leveling layer is polymer mortar, the crack-resistant layer is fiberglass mesh, and the insulation layer is fire-retardant or fireproof insulation board, etc. The external wall insulation structure is composed of these materials and is installed on-site by bonding. Examples of fireproof external wall insulation boards include graphite-modified cement-based insulation boards, rock wool boards, foamed cement boards, and foamed ceramic insulation boards. Examples of fire-retardant external wall insulation boards include fire-retardant molded polystyrene foam boards (EPS) or extruded polystyrene boards (XPS). External wall insulation boards are lightweight and lack rigidity; therefore, their characteristics must be considered when fixing them. Consequently, with current technology, cases of external wall insulation boards detaching frequently occur.

[0003] In existing technology, the main component of thermal insulation wall panels is the insulation board, and its connector is mainly thermal nail. The insulation nail is used to fix the wall to the building surface, which is also the main fixing structure of the external wall insulation wall panel. However, this kind of fixing method often causes the insulation material of the building's external wall to fall off, which is very dangerous and also affects the insulation effect. In order to further strengthen the fixing of the insulation layer of the thermal insulation wall panel, improve the fixing method of the connector, and ensure the insulation effect, it is necessary to design an external wall insulation board connector.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 An external wall insulation board connector includes an insulation board 1, which is the main material of the building insulation wall panel structure and also the main fixed assembly part. The insulation board 1 has a rectangular surface structure. Multiple insulation boards 1 are spliced ​​together on the wall panel plane to form an insulation layer structure laid on the building wall. Notches 2 are opened at the four corners of the insulation board 1. The four sets of notches 2 of four adjacent sets of insulation boards 1 are spliced ​​together to form a round hole.

[0027] Insulation nails 3 are installed inside the round holes formed by the four sets of notches 2 to fix the insulation board 1 to the wall of the building. In other words, the insulation board 1 is pressed and fixed to the wall by the insulation nails.

[0028] It also includes an auxiliary pressing and fixing mechanism, which is used to simultaneously press the four adjacent sets of insulation boards 1 after splicing;

[0029] The auxiliary clamping and fixing mechanism presses the insulation board 1 with the insulation nail 3, thereby assisting the conventional insulation nail connector in better clamping and fixing the insulation board, preventing the insulation board from falling off, and improving the stability of the external wall insulation board fixing.

[0030] Furthermore, the auxiliary clamping and fixing mechanism includes a clamping ring 4, on which a through hole 5 is coaxially provided for the insulation nail 3 to pass through, so that the insulation nail 3 is assembled at the position of the through hole 5.

[0031] Four sets of pressure plates 6 are evenly distributed around the outer circumference of the clamping ring 4. The four sets of pressure plates 6 are used to press and cover the splice seams between the four sets of insulation boards 1. That is, after the insulation nail 3 is installed in the through hole 5, the clamping ring 4 further assists the insulation nail 3 in pressing and fixing it on the four sets of insulation boards 1. At the same time, the four sets of pressure plates 6 press and cover the splice seams between the four sets of insulation boards 1. While achieving the pressing and fixing of the four sets of insulation boards 1, it can also play a certain role in sealing the splice seams and improving the insulation effect of the insulation board 1.

[0032] Furthermore, a hidden groove 7 is coaxially provided on the clamping ring 4 and communicates with the through hole 5 so that the nail head of the insulation nail 3 is embedded in the hidden groove 7, so as to avoid too many protrusions on the surface of the insulation board structure and ensure the flatness of the exterior wall surface.

[0033] Furthermore, an arc-shaped plate 8 is provided between each pair of adjacent pressure plates 6 in the four sets of pressure plates 6. The arc-shaped plate 8 not only ensures the structural stability of the four sets of pressure plates 6, but also plays a role in further pressing them onto the insulation board 1, so as to further improve the fixing effect of the insulation board 1.

[0034] Furthermore, a clamping ring 4 is connected to the center of the arc plate 8, and the clamping ring 4 is then fixed by a heat insulation nail 3. Holes are drilled in the corresponding position of the clamping ring 4 on the heat insulation plate 1 to install the heat insulation nail 3 for fixation, thereby realizing multi-point fixation of the auxiliary clamping and fixing mechanism, and thus also realizing multi-point fixation of the heat insulation plate 1, so as to achieve more stable fixation of the heat insulation plate 1.

[0035] In summary, this device, through an auxiliary clamping and fixing mechanism, assists conventional insulation nail connectors in better clamping and fixing the insulation board, preventing the insulation board from falling off and improving the stability of the external wall insulation board fixing.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
