Description

A thermal insulation and sound absorption composite wall

technical field

The utility model relates to the technical field of building structural components, in particular to an insulating and absorbing composite wall suitable for the outer walls of industrial workshops.

Background technique

From the perspective of building structure, the wall is an important part of the building, and it is also a key factor related to the performance and service life of the building. In addition to its maintenance function, the characteristics of industrial plants also require the exterior walls to be lightweight, high-strength, sound-absorbing, thermal-insulating, and durable.

The existing exterior walls of industrial plants mainly include masonry block walls, cast-in-place concrete walls, lightweight panels, color steel and sandwich panel walls, etc., and the above-mentioned exterior walls have some shortcomings during construction and use. For example, masonry block walls and cast-in-place concrete walls must be wet-worked on site, the construction environment is harsh, and the masonry block walls and cast-in-place concrete walls have relatively high self-weight and require high foundations. For example, the commonly used color steel and sandwich panel wall panels meet the requirements of small weight and high strength, but their durability is poor and they are easy to fade, especially in acid rain, salt, alkali and other environments. The noise reduction performance is poor, and the maintenance cost is high in the later period; and the wind resistance performance is poor. In severe weather such as typhoons, the wallboards are often blown off in whole.

Utility model content

The utility model provides a heat-preservation and sound-absorbing composite wall body, and the purpose is to provide a light-weight, high-strength, high-durability composite wallboard for industrial workshops with multi-layer sound-absorbing and heat-preserving performances.

In order to realize the above-mentioned purpose of the invention, the technical scheme that the utility model takes is as follows:

A heat-insulating and sound-absorbing composite wall, comprising an outer wall panel, a wall keel, and an insulating layer, and also including a sound-absorbing layer and several sound-absorbing cavities; The block and the keel of the wall are formed, the ends of the bumps are supported on the keel of the wall, and the sound-absorbing layer is attached to the inner surface of the thermal insulation layer.

Further, the exterior wall panels are formed by inserting tongue and groove Jinbang panels.

Further, the outer surface of the insulation layer is pasted with a waterproof and breathable film.

Further, the insulation layer is a rock wool board or a glass wool board.

Further, the sound-absorbing layer is a sound-absorbing mineral wool board.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model also includes a sound-absorbing layer and a plurality of sound-absorbing cavities to form double sound-absorbing, good sound-absorbing and noise-reducing performance, and is especially suitable for high-noise production workshops.

The sound-absorbing cavity is formed by the spaced bumps on the insulation layer and the wall keel. The structure is simple and the construction is convenient, and the size of the sound-absorbing cavity can be adjusted to meet different sound absorption and heat preservation requirements. Require.

By setting the external wall to be made of tongue-and-groove Jinbang panels, the Jinbang panels have been embossed and painted in the factory, which has a good decorative effect and overcomes the problems of monotonous decorative effect of ceramic tiles and light pollution of glass curtain walls.

The wall body of the utility model can be cut into standard boards after being prefabricated in the factory and transported to the construction site for construction, which can realize dry work on the construction site to reduce construction waste and environmental pollution, and is not affected by the construction environment.

The composite wall with Jinbang board as the outer wall board has excellent fireproof performance.
