Description

A multi-layer composite insulation board Technical Field

[0001] This utility model relates to the field of composite board technology, specifically a multi-layer composite insulation board. Background Technology

[0002] Insulating boards, also known as insulating mats, insulating pads, insulating sheets, or insulating blankets, are widely used in substations, power plants, power distribution rooms, laboratories, and for live-line work in the field.

[0003] However, the existing technology has the following drawbacks:

[0004] Existing insulation boards are only single-layer structures, which have poor strength and may break or be damaged during use, requiring frequent replacement. They have a relatively short service life and increase costs. Their performance is also relatively limited, limiting their application scenarios. They are few and single in number, with a small range of applications, and need to be used in combination with other materials, which is quite complicated. Summary of the Invention

[0005] The purpose of this invention is to provide a multilayer composite insulation board to solve the problems mentioned in the background art.

The structure of the second card slot and the structure of the first card block are the same as the structure of the first card slot and the structure of the second card block, respectively. The interior of the first card slot and the interior of the second card slot are coated with glue.

[0013] Using the above technical solution, the limiting groove can prevent the card block from falling off and sliding out, thus playing a fixing role. The first card block and the second card block are respectively bonded to the second card slot and the first card slot with glue, which plays a reinforcing role.

[0014] The inner wall of the base layer is provided with a vacuum cavity, and a number of reinforcing plates are evenly arranged inside the vacuum cavity. The reinforcing plates are inclined and adjacent reinforcing plates are connected end to end, forming a triangular columnar cavity between adjacent reinforcing plates.

[0015] Using the above technical solution, the vacuum cavity has a sound insulation function, and the reinforcing plate plays a role in strengthening the base structure.

[0016] The base layer is a wooden board with a fireproof coating evenly applied to its surface. The length of the reinforcing plate is the same as the inner length of the vacuum cavity, and the front and rear ends of the reinforcing plate are in close contact with the inner walls of the front and rear ends of the vacuum cavity.

[0017] Using the above technical solution, the wood-based panels have sound-absorbing properties, which can reduce noise, and a triangular cavity is formed between two adjacent reinforcing panels, making it more stable.

[0018] The insulating layer has a second threaded through hole at each of its four corners, the connecting layer has a first threaded through hole at each of its four corners, and the base layer has a threaded hole at each of its four corners on the top and bottom sides. The second threaded through hole, the first threaded through hole, and the threaded hole are respectively provided, and screws are installed sequentially inside each of them.
