Description

External wall panel structure

The utility model relates to a building material, in particular to an outer wall panel structure.

Background technique

With the rapid development of modern science and technology, as well as people's requirements for complete functions, convenient use, comfortable living, safety and energy saving, and good health, the low-rise residential buildings in foreign countries generally adopt light frame structure, and China is still in its infancy. Its building structure is to build a skeleton of the house with wooden keel or light steel keel. After the roof is built, the outer wall is constructed. The following schemes are usually used in construction:

1. Use gray bricks or concrete blocks to make walls. Bricks have high labor costs, long construction period, and high labor intensity. The production of bricks is also very damaging to the environment; the inadequacies of cement blocks are self-important, require mechanical construction, high cost, and after the blocks are filled, they have to be done outside. The decoration of the paint, etc., takes time and effort;

2. Use aerated concrete slabs to make walls. In the construction, the connecting piece needs to be connected with the skeleton of the house. The shortcoming of this construction method is self-important, which increases the construction difficulty, and the plate itself is limited by the size, resulting in more joints, which brings a lot of inconvenience to the construction;

3. Use a polystyrene board to make the wall directly. In the construction, the polystyrene board is directly connected to the skeleton of the house by screws and washers, and then the reinforcing net, the plastering process and the like are added, so that the on-site three-dimensional construction increases the construction difficulty, and the operator's technical level is relatively high, time-consuming and laborious.

Summary of the invention

The purpose of the utility model is to provide a step by step to improve the quality of the house and improve the earthquake resistance, all the processes are completed in the factory, and the wet work on the site is reduced, thereby speeding up the construction speed, saving the cost, saving labor, and reducing the difficulty of the construction of the outer wall panel structure. body.

The technical solution of the utility model is: an outer wall panel structure, the outer wall panel structure is fixed to the structural frame of the building for constituting the outer wall, comprising a core material and a surface layer, and the surface of the core material is opened There is a longitudinal straight through groove in which the core material is wrapped. The surface layer is directly covered on the core material, which reduces wet work on site installation, speeds up construction, saves cost, saves labor, reduces construction difficulty, and has a vertical straight groove on one side of the core material to make the outer wall panel structure resist The performance is greatly improved, and during installation, the mounting bolt can be screwed into the straight through slot and the outer wall panel structure can be fixed on the building, and the bolt head can be completely immersed in the straight through slot, so that the outer surface is a flat surface, which is not only beautiful and elegant. It is easy to scrape the putty and brush the exterior wall paint, and the straight through groove can also play the role of further fixing the bolt. Further, a sidewall of the through slot is perpendicular to a bottom surface of the through slot or a sidewall of the through slot and a plane where the bottom surface of the through slot is located. The flexural performance is best when the side walls and the bottom surface are at right angles or at an acute angle therebetween.

Further, the core material is a lightweight insulation material.

Further, the lightweight insulation material is EPS or asbestos and rock wool.

Further, the surface layer is made of a plaster or a mixture of a styrene-acrylic or pure propylene solution and quartz sand or a hot melt by adding wood chips to the plastic granules.

The utility model has the advantages and positive effects: due to the adoption of the above technical solution, it has the advantages of light weight, energy saving, fireproof and heat preservation, simple process, convenient installation and use, industrial scale production, further improvement of housing quality, improvement of earthquake resistance, and acceleration of construction speed , cost saving, labor saving, economical and practical.

detailed description

As shown in Fig. 1 and Fig. 2, the utility model comprises a core material 1 made of EPS or asbestos and rock wool, and the material is a mortar or a mixture of styrene or propylene or pure propylene solution and quartz sand or plastics added by crushed wood chips. The surface layer 2 is formed by hot-melting particles, and a surface of the core material 1 is opened with a longitudinal straight groove 3, and the core material 1 is wrapped in the surface layer 2.

As shown in FIG. 3 and FIG. 4, the side wall 4 of the through slot 3 is perpendicular to the bottom surface 5 of the through slot 3 or the side wall 4 of the through slot 3 and the bottom surface 5 of the through slot 3 Form an acute angle.

Embodiment 1 : preparing an exterior wall panel structure,

The outer wall panel structure of the utility model, as shown in FIG. 1 to FIG. 3, comprises a core material 1 and a surface layer 2.

The preparation method is as follows: 1. Take a 1200mmx3000mmx80mm core material 1 made of EPS, and make three straight grooves 3 with a width of 20mm and a depth of 20 mm in one longitudinal direction. The side wall 4 of the straight through groove 3 is perpendicular to the bottom surface of the straight through groove 3. 4, the spacing between the adjacent two straight through slots 3 is 90mm;

2. Make the plaster on the whole periphery of the core material 1 5mm thick. The place with the straight groove 3 is filled with the mortar, so that the outer surface of the surface layer 2 grows in a square shape, and the outer wall panel structure product is obtained after drying.

The installation process of the present example: as shown in FIG. 5, the outer wall panel structure is placed on the wall surface 7, the bolt 6 is screwed in the straight through slot 3, and the outer wall panel structure is fixed on the wall surface 7, and Rotate the bolt 6 to be flush with the outer surface of the surface layer 2.
