Wallboard and side fascia connection structure in ALC

Technical Field

The utility model relates to the field of assembly type buildings, in particular to a connecting structure of an ALC inner wallboard and an outer wallboard.

Background

In the field of buildings, the demands of people on building industrialization are changed silently, concepts such as green buildings, sustainable development, energy conservation and emission reduction are gradually deeply paid attention to, and the conversion from the traditional extensive building production mode to intensive building becomes a key problem facing the current building industry. Under the background of the large environment, the assembly type building not only breaks through the limitation in the traditional house construction process, provides effective guarantee for the construction quality of the building engineering by utilizing advanced technical means, but also can effectively solve the phenomenon of labor resource shortage in the building market. Currently, the structural forms of the fabricated building are mainly classified into a fabricated concrete building and a fabricated steel structure building. Because the construction price of the fabricated concrete is relatively low, the fabricated concrete is widely applied to actual engineering.

At present, autoclaved aerated concrete (ALC) slabs are adopted in a large number of walls in fabricated buildings. The ALC board has the effects of heat preservation, heat insulation, sound insulation, shock resistance and the like, and is a novel building material with excellent performance. The ALC board is loose and porous in texture, so that the strength of the ALC board is low. And the ALC board only depends on a large number of uniform and non-communicated tiny air holes in the ALC board for heat preservation, and the heat preservation capability needs to be improved. In addition, because the size of a single ALC board is limited, when the ALC board is used as a wall board, splicing is needed, and the strength, sealing, fire-proof and heat-insulating properties of the splicing position are very important to the quality of the whole building.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a connecting structure of an ALC inner wallboard and an outer wallboard, which improves the strength, sealing, fire-proof and heat-insulating properties of a connecting position and the overall quality of the whole fabricated building.

The purpose of the utility model is realized as follows: the utility model provides a wallboard and side fascia connection structure in ALC, the side fascia is formed by two ALC boards piecing together, and piecing together the position inboard and being equipped with the rectangle steel-pipe column, interior wallboard is connected perpendicularly in rectangle steel-pipe column inboard, between side fascia and the rectangle steel-pipe column, all filled between interior wallboard and the rectangle steel-pipe column has the rock wool, and other positions in the rectangle steel-pipe column outside are equipped with fireproof coating layer, and it has the PU foamer to piece together to fill between the position. The ALC inner wallboard and outer wallboard connecting structure has good supporting strength and fireproof and heat-insulating properties.

As a further improvement of the utility model, the outer side of the PU foaming agent close to the outer surface of the external wall panel is sequentially provided with a PE rod, sealant and caulking agent from inside to inside, and the inner side of the PU foaming agent close to the inner surface of the external wall panel is filled with the caulking agent, thereby further improving the heat preservation and insulation sealing performance of the splicing position of the external wall panel.

As a further improvement of the utility model, alkali-resistant mesh cloth is adhered to the outer side of the splicing position, the corners of the external wall plate and the fireproof coating layer, and the corners of the internal wall plate and the fireproof coating layer, so that the heat-insulating anti-cracking performance of the connecting position is further improved.

As a further improvement of the utility model, the thickness of the fireproof coating layer is 50-100 mm, so that the fireproof performance of the connecting position is ensured.

As a further improvement of the utility model, the polymer waterproof mortar layer is arranged on the inner side and the outer side of the external wall panel and the outer side of the fireproof coating layer, so that the waterproof and anti-cracking performance and the supporting strength of the connecting position are further improved.

As a further improvement of the utility model, concrete is poured into the rectangular steel pipe column, so that the support strength of the connecting position is further improved.

As a further improvement of the utility model, the outermost side of the external wall panel is provided with an insulating layer and a decorative layer, so that the insulating property and the aesthetic property of the wall body are further improved.
