Description

Building exterior wall fire insulation board

technical field

The utility model relates to the improvement of the structure of the thermal insulation board of the outer wall of the building.

Background technique

At present, in order to meet the requirements of environmental protection and energy saving, the traditional method is to lay benzene panels on the exterior walls of buildings; although benzene panels have good heat insulation functions, their fire performance is poor, and the fire rating is only B ₁ , which is difficult to meet some Buildings with higher fire protection requirements.

In order to make the exterior wall of the building meet the A-class fire protection standard, it is necessary to use the A-class fire-proof insulation material; however, the cost of the A-class fire-proof insulation material with good thermal insulation performance is generally high, and the construction is inconvenient.

Contents of the invention

The utility model aims at the above-mentioned problems and provides a fire-proof and heat-preservation board for the outer wall of a building with good thermal insulation performance, low cost, easy construction, and a system fireproof grade that can reach Class A.

In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme, the utility model comprises benzene board, and its structural points are provided with grooves on the benzene board, and A-level fireproof and heat-insulating materials are arranged in the groove, benzene board and A A fireproof layer is arranged outside the grade fireproof and thermal insulation material, and the fireproof layer is composed of a mortar layer and mesh cloth inside or outside.

Beneficial effects of the utility model: 1. Simple structure and convenient processing: when the utility model is processed, only grooves need to be made on the benzene plate, and then A-level fireproof and thermal insulation materials are embedded in the grooves on the benzene plate, and then placed on the benzene plate. A fireproof layer composed of mesh cloth and mortar layer can be set outside the board, the structure is simple, and the production and processing are convenient.

2. Good fireproof performance: the utility model sets A-class fire-proof and heat-insulating materials in the groove of the benzene board, which improves the fire-proof performance of the composite heat-preservation board, and the utility model is also outside the benzene board and the A-class fire-proof and heat-preservation material A fireproof layer is set, which further improves the fireproof performance of the whole system after the utility model is installed on the wall, so that the overall fire protection level of the utility model after the wall is installed reaches Class A.

3. Good heat preservation performance: the utility model adopts the combination form of benzene board and A-grade fireproof heat preservation material with low heat transfer coefficient, which constitutes the main body of the heat preservation board of the present invention, and its heat preservation effect is equal to that of the existing benzene board, thereby ensuring The overall thermal insulation performance of the utility model is improved, and the energy-saving requirements of buildings can be fully met.

4. Strong adaptability: the utility model has a simple structure and can also be processed and manufactured at the construction site; during construction, since the main body of the utility model is benzene board, the benzene board is easy to process and polish, and when the flatness of the outer wall of the building is not good, it can be Part of the benzene board is processed into the required shape on site, and then the whole insulation board is pasted; therefore, the utility model can adapt to the situation that the flatness of the outer wall of the building is not good.

5. Low cost: The utility model adopts the combination of benzene board and A-grade fireproof and heat-insulating material, which reduces the use of A-grade fire-proof and heat-insulating materials, thus reducing the material cost and construction cost of traditional A-grade fire-proof and heat-preserving boards.
