Abstract

The utility model provides a school building compound wallboard, relates to the field of the building materials, and in particular relates to a multifunctional compound wallboard applicable to the occasions such as school classrooms and lecture halls. The school building compound wallboard is provided with a wallboard body which comprises a middle composite layer (3), an inner layer (1) and an outer layer (2). The school building compound wallboard is characterized in that the inner layer and the outer layer are formed by aluminum alloy plates, respectively, corrugated convex strips (5) and evenly distributed sound attenuation holes (4) are formed on or in the surface of the inner layer, and the middle composite layer is any one of a straw pressed board, a polyurethane foam board and an asbestos fiber board. The inner layer of the school building compound wallboard is capable of weakening the echo, while the composite layer is capable of achieving the effects of sound insulation and heat insulation, and therefore, the school building compound wallboard is especially applicable to the occasions such as music classrooms, lecture halls and lecture rooms and has positive effects of heat insulation, sound attenuation and sound insulation.

Description

Building combined wall board for school

Technical field

The utility model relates to building material field, particularly belongs to a kind of multifunction composite wall panel that is suitable for the occasions such as classroom, Conference Hall.

Background technology

At present, the non-lbearing wall material generally using in construction market is at home mainly by refinforced cement, haydite concrete, enhancing gypsum hollow lath etc.; Although this type of materials for wall is made simple, but most of materials all exist, and quality is heavier, environment pollution, be difficult to the problems such as recycling, and do not have erasure effect, sound insulation, heat insulation effect are not good yet, are not suitable for the application for some special occasions such as classroom, Conference Halls.

Summary of the invention

The purpose of this utility model is to provide building combined wall board for a kind of novel school, alleviates wall weight, makes the object of simple, sound insulation and sound-absorbing and high insulating effect to reach.

Building combined wall board for school provided by the utility model, have wallboard body, in the middle of described wallboard body comprises, composite bed, internal layer and skin, is characterized in that, internal layer and skin consist of aluminium alloy plate respectively, and inner layer sheet mask has striped and the equally distributed bloop of corrugated projection; Described middle composite bed is any one in straw pressboard, polyurethane foam, asbestos fiber sheet.

Building combined wall board for school provided by the utility model, for green environment protection ligh wall material, on aluminium alloy plate due to internal layer, be provided with striped and the bloop of corrugated projection, can weaken echo, the existence of middle composite bed can be played the effect of sound insulation and insulation again, therefore be particularly suitable for the occasions such as music room, Conference Hall, classroom, there is the good effect of heat-insulation and heat-preservation, noise reduction, sound insulation.

Accompanying drawing explanation

Accompanying drawing partly discloses specific embodiment of the utility model, wherein,

Fig. 1, the utility model perspective view;

Fig. 2, the utility model section structure schematic diagram.

The specific embodiment

In embodiment as shown in Figure 1, building combined wall board for school provided by the utility model, there is wallboard body, composite bed 3, internal layer 1 and outer 2 in the middle of comprising, wherein, internal layer and skin adopt respectively aluminium alloy plate to be made, and are provided with striped 5 and the even densely covered bloop 4 of corrugated projection on internal layer, thereby play the effect of noise reduction, sound-absorbing.

Described middle composite bed, is any one in straw pressboard, polyurethane foam, asbestos fiber sheet, has the effect of sound insulation, insulation.Wherein, take asbestos fiber sheet as best, because it has fire-retardant effect simultaneously.For the ease of with internal layer, outer field combination, and strengthen heat insulation effect, the two sides of middle composite bed also can be provided with damping rubber.

Middle composite bed both sides are respectively arranged with connection projection 7 and the link slot 6 cooperatively interacting, and are convenient to be interconnected with one another, and are beneficial to installation.

Claims (2)

1. a school is with building combined wall board, there is wallboard body, composite bed (3), internal layer (1) and skin (2) in the middle of described wallboard body comprises, it is characterized in that, internal layer and skin consist of aluminium alloy plate respectively, and inner layer sheet mask has striped (5) and the equally distributed bloop (4) of corrugated projection; Described middle composite bed is any one in straw pressboard, polyurethane foam, asbestos fiber sheet.

2. building combined wall board for school according to claim 1, is further characterized in that, described middle composite bed both sides are respectively arranged with connection projection (7) and the link slot (6) cooperatively interacting.
