Description

A crack-resistant prefabricated building that uses fasteners to quickly tighten

technical field

The utility model belongs to the technical field of construction, in particular to an anti-cracking prefabricated building that utilizes fasteners to quickly tighten.

Background technique

Prefabricated building is the abbreviation of reinforced concrete building prefabricated structure and steel structure prefabricated building structure. Prefabricated building structure is one of the important directions of building structure development in my country. It is conducive to the development of building industrialization, improving production efficiency, saving energy, developing green and environmentally friendly buildings, and helping to improve and ensure the quality of construction projects. Compared with the cast-in-place construction method, the prefabricated structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction, such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment, including Reduce noise, prevent dust, reduce environmental pollution, clean transportation, reduce site disturbance, save water, electricity, materials and other resources and energy, and follow the principle of sustainable development.

A prefabricated building is a building assembled from prefabricated parts at the construction site, which is called a prefabricated building. According to the form and construction method of prefabricated components, it is divided into five types: block building, plate building, box building, skeleton plate building and rising plate building.

The panel building described therein is assembled from prefabricated large-scale interior and exterior wall panels, floor slabs, and roof panels, and is also called large-slab building. It is the main type of fully assembled buildings in industrialized system buildings. Plate construction can reduce the weight of the structure, improve labor productivity, expand the usable area and shock resistance of the building. The inner wall panels of panel buildings are mostly reinforced concrete solid panels or hollow panels; the outer wall panels are mostly reinforced concrete composite panels with thermal insulation layers, and can also be made of lightweight aggregate concrete, foamed concrete or macroporous concrete. Exterior finish wall panels. The equipment in the building often adopts centralized indoor pipe fittings or box toilets to improve the degree of assembly. The key issue of slab building is node design. In terms of structure, the integrity of the connection of the components should be ensured (the connection methods between the plates mainly include welding and post-cast concrete integral connection). In the waterproof structure, it is necessary to properly solve the waterproofing of the joints of the exterior wall panels, as well as the thermal treatment of the floor joints and corners. The main disadvantage of large-slab building is that it has great constraints on the shape and layout of the building; the internal separation of large-slab buildings with lateral load-bearing small bays lacks flexibility (longitudinal wall type, inner column type and large-span floor type can be flexible inside. separated).

However, the existing plates are connected individually in pairs, which not only has poor assembly efficiency, but also easily causes the problem of cracking between the plates.

The combined wall panel structure is a vertical wall structure fixed on the ground or other platforms, and is also the main load-bearing carrier. Each combined wall panel is a plane structure, and is turned and connected to another combined wall panel through the connecting plate 3, so that a ring-shaped structure is formed by a plurality of combined wall panels. The bottom surface of the annular structure is the ground, and the top is covered by the provided top plate 2, thereby forming an independent space separately.
