Composite integral heat-insulation assembled large wallboard and manufacturing method thereof

Abstract

The invention discloses a composite integral thermal insulation assembled large wallboard which is a combined wallboard and is formed by assembling a plurality of lightweight concrete wallboards. The upper ends and the lower ends of the multiple lightweight concrete wallboards are fixedly connected with reinforced concrete connection beams or angle steel. Flat steel is fixedly arranged on the periphery of a door and window opening reserved in the large composite overall heat preservation assembly wallboard. The lightweight concrete wallboard comprises a base layer board, a bonding layer, a heat preservation board and a protective layer. The base layer plate, the bonding layer, the heat preservation plate and the protection layer are connected into a whole through a plurality of fixing connecting pieces. One side, in the height direction of the lightweight concrete wallboard, of the base layer board is sunken inwards to form a groove, and the other side of the base layer board protrudes outwards to form a clamping column matched with the groove; one side of the protective layer protrudes outwards to form a protruding L-shaped structure, and the other side of the protective layer correspondingly sinks inwards to form a retracted L-shaped structure. The heat-insulating plate has an excellent heat-insulating effect, and is convenient to manufacture, stable in structure and convenient to assemble.

Description

technical field [0001] The invention relates to the technical field of building wall panels, in particular to a composite integral thermal insulation assembly large wall panel and a manufacturing method thereof. Background technique [0002] With the continuous improvement of building energy and labor costs in my country, in recent years, prefabricated buildings have received more and more attention from governments at all levels and from all walks of life, and a series of encouragement and support policies have also been formulated at the national level. In addition to the main structure, the "three panels" of the building are the preferred components of the prefabricated technology, and the most difficult to overcome is the prefabricated prefabricated external wall panel technology. The exterior wall of the building has various functions such as wall enclosure, thermal insulation, fire prevention, and wind resistance, and at the same time bears various load effects such as...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing integrated thermal insulation wall panels are made of lightweight concrete materials. Due to the limitation of technological conditions, the size of the prefabricated wall panels is difficult to achieve the assembly of the whole wall.

Assembling multiple wall panels on site, it is difficult to deal with construction gaps, and water leakage and water seepage are unavoidable; at the same time, the assembly effect of multiple wall panels is limited, losing the true meaning of prefabricated buildings
