Description

Technical Field

[0001] This utility model relates to the field of building wall panel technology, and in particular to an integrated fiber composite thermal insulation wall panel. Background Technology

[0002] Fireproof exterior walls are commonly used wall panels in the construction industry. Existing firewalls usually use brick-concrete composite exterior wall panels, which generally have problems such as long construction period, great influence of environmental factors, wet work on site, and high overall cost.

[0003] For example, in the prior art, the patent with authorization announcement number CN217480602U discloses an integrated fiber cement composite wall panel, which uses a metal frame for internal and external fixation sandwich central frame structure, is filled with thermal insulation material, and has a four-sided tongue and groove structure, which facilitates wall panel installation, improves work efficiency, and has strong strength, thermal insulation, weather resistance and fire resistance.

[0004] However, the metal frame structure of the device is connected to the fiber cement board by bolts, which can easily lead to gaps between the metal frame and the fiber cement board. Moisture in the air can enter the insulation layer through the gaps, causing the fireproof and heat-insulating material of the insulation layer to absorb moisture, affecting the insulation performance and overall strength. Therefore, an integrated fiber composite insulation wall panel was designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose an integrated fiber composite thermal insulation wall panel.

[0006] The technical problem to be solved by this utility model is to provide an integrated fiber composite thermal insulation wall panel, which solves the problem that the existing integrated fiber cement composite wall panel has poor sealing performance of the insulation layer, which easily allows moisture in the air to enter the insulation layer, causing the fireproof and thermal insulation material of the insulation layer to absorb moisture, thus affecting the thermal insulation performance and overall strength.

[0007] This utility model provides an integrated fiber composite thermal insulation wall panel, including a thermal insulation layer, a metal frame, and fiber cement boards. Two fiber cement boards are respectively disposed on the upper and lower surfaces of the metal frame to form a sandwich structure. A thermal insulation layer is disposed on the inner side of the metal frame. The side length of the fiber cement board is greater than the side length of the metal frame, and the center of the fiber cement board overlaps with the center of the metal frame. The edge of the fiber cement board and the edge of the metal frame form a sandwich-type tongue and groove. A square metal frame is integrally formed on the contact surface between the fiber cement board and the metal frame. The metal frame is welded onto the square metal frame. A high-strength adhesive layer is disposed on the contact surface between the thermal insulation layer and the fiber cement board.

[0008] Preferably, the high-strength adhesive layer is made of polyurethane.

[0009] Preferably, a high-strength adhesive layer is also provided on the contact surface between the metal frame and the insulation layer.

[0010] Preferably, the metal frame is threaded with fixing bolts on all four sides, and the fixing bolts are threaded onto the four sides of the insulation layer.

[0011] Preferably, the insulation layer is made of fire-resistant and heat-insulating material.

[0012] Preferably, the insulation layer is one or both of rock wool and glass wool.

[0013] Preferably, the fiber cement board is provided with a fiber cement layer, a primer coating, a topcoat coating and a nano self-cleaning coating in sequence from the inside to the outside.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. The edge of the fiber cement board of this utility model forms a sandwich-type tongue and groove with the edge of the metal frame, which makes the assembly more convenient by inserting the wall panel into the keel through the sandwich-type tongue and groove around the perimeter and then fixing the keel wall column.

[0016] 2. This utility model features a square metal frame integrally formed with a fiber cement board. When connecting the fiber cement board and the metal frame, the metal frame is welded to the square metal frame, which increases the sealing between the metal frame and the fiber cement board, prevents moisture in the air from entering the insulation layer inside the metal frame, prevents the fireproof insulation material inside the insulation layer from absorbing moisture, and ensures the insulation performance of the insulation layer.

[0017] 3. This utility model, by setting a high-strength adhesive layer, makes the contact between the insulation layer and the fiber cement board closer, improves the overall strength of the wall panel, and increases the sealing and sound insulation effects. Attached Figure Description

[0025] Example:

[0026] like Figures 1-4 As shown, an embodiment of this utility model provides an integrated fiber composite thermal insulation wall panel, including a thermal insulation layer 1, a metal frame 2, and a fiber cement board 3. Two fiber cement boards 3 are respectively disposed on the upper and lower surfaces of the metal frame 2 to form a sandwich structure. The thermal insulation layer 1 is disposed on the inner side of the metal frame 2. The side length of the fiber cement board 3 is greater than the side length of the metal frame 2, and the center of the fiber cement board 3 overlaps with the center of the metal frame 2. The edge of the fiber cement board 3 and the edge of the metal frame 2 form a sandwich-type tongue and groove. A square metal frame 4 is integrally formed on the contact surface between the fiber cement board 3 and the metal frame 2. The metal frame 2 is welded onto the square metal frame 4. A high-strength adhesive layer 101 is disposed on the contact surface between the thermal insulation layer 1 and the fiber cement board 3.

[0027] The fiber cement board 3 of this utility model forms a sandwich-type tongue and groove with the edge of the metal frame 2, which makes the installation process more convenient by inserting the wall panel into the keel with the sandwich-type tongue and groove around the perimeter, and then fixing the keel wall column.

[0028] By setting up a square metal frame 4, which is integrally formed with fiber cement board 3, and connecting the fiber cement board 3 and the metal frame 2, the connection is made by welding the metal frame 2 to the square metal frame 4, thereby increasing the sealing between the metal frame 2 and the fiber cement board 3, preventing moisture in the air from entering the insulation layer 1 inside the metal frame 2, preventing the fireproof insulation material inside the insulation layer 1 from absorbing moisture, and ensuring the insulation performance of the insulation layer 1.

[0029] By setting a high-strength adhesive layer 101, the contact between the insulation layer 1 and the fiber cement board is made closer, which improves the overall strength of the wall panel and increases the sealing and sound insulation effects.

[0030] In this embodiment, the high-strength adhesive layer 101 is made of polyurethane. Polyurethane high-temperature adhesive, with its excellent high-temperature resistance and strong bonding ability, can still maintain stable physical and chemical properties under extreme temperature conditions.

[0031] In this embodiment, a high-strength adhesive layer 101 is also provided on the contact surface between the metal frame 2 and the insulation layer 1.

[0032] By providing a high-strength adhesive layer 101 on the contact surface between the metal frame 2 and the insulation layer 1, the high-strength adhesive layer 101 can seal the insulation layer 1 from the side, further preventing moisture in the air from contacting the insulation layer 1, preventing the fireproof insulation material inside the insulation layer 1 from absorbing moisture, and ensuring the insulation performance of the insulation layer 1.

[0033] In this embodiment, fixing bolts 201 are threaded on all four sides of the metal frame 2, and the fixing bolts 201 are threaded on the four sides of the insulation layer 1. The metal frame is fixed to the insulation layer 1 by fixing bolts 201, which increases the stability of the metal frame 2 when it wraps the insulation layer 1.

[0034] In this embodiment, the insulation layer 1 is made of fireproof and heat-insulating material. The insulation layer 1 is one or both of rock wool and glass wool. Both rock wool and glass wool have good heat insulation and heat preservation effects.

[0035] In this embodiment, the fiber cement board 3 is provided with a fiber cement layer 301, a primer coating 302, a topcoat coating 303 and a nano self-cleaning coating 304 from the inside to the outside, so that the fiber cement board 3 has self-cleaning ability and no secondary treatment is required on the exterior wall after assembly.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
