Light-weight high-strength prefabricated slab for building

Abstract

The invention belongs to the technical field of building slabs, and particularly relates to a light-weight high-strength prefabricated slab for a building. The light-weight high-strength prefabricatedslab for the building comprises a prefabricated slab frame, wherein a prefabricated slab filling cavity is arranged in the prefabricated slab frame; cement slabs, reinforcing ribs, wire reinforcementmeshes and circular cavity pipes are sequentially arranged at the top end of the inner part of the prefabricated slab filling cavity; and the cement slabs, the reinforcing ribs and the wire reinforcement meshes are symmetrically distributed at the top ends and the bottom ends of the circular cavity pipes. The double-layer reinforcing ribs and the wire reinforcement meshes are combined, so that the manufactured prefabricated slab has favorable hardness and strength, the overall strength of the distribution positions of the circular cavity pipes can be improved, the overall stability of the prefabricated slab is improved, the occurrence of the phenomenon that the prefabricated slab is locally weak due to the distribution of the circular cavity pipes is avoided, and the overall firmness of the prefabricated slab is improved; and the reinforcing ribs and the wire reinforcement meshes are made of cold-drawing low-carbon steels, and high-strength light-weight aggregate cores additionally arranged in the cement slabs are combined, so that the overall firmness of the prefabricated slab is improved.

Description

technical field [0001] The invention belongs to the technical field of building boards, in particular to a light-duty high-strength prefabricated board for construction. Background technique [0002] With the rapid development of the construction industry, many new building materials have emerged. And these building material pairs can make better and more perfect buildings. Among them, cement prefabricated board is one of the most typical materials. Cement prefabricated slab is a prefabricated wall made of Portland cement and steel keel. It is a plate made of formwork, so it is named cement prefabricated slab. Because it is a concrete prefabricated part produced and processed in the prefabrication field, it is directly transported to the construction site for installation, so it is called a prefabricated panel. After the reinforcement, fill the hollow part with cement, knock off the board after it dries, and the rest is the prefabricated board. The prefabricated board has...

Cement prefabricated slab is a prefabricated wall made of Portland cement and steel keel. It is a plate made of formwork, so it is named cement prefabricated slab. Because it is a concrete prefabricated part produced and processed in the prefabrication field, it is directly transported to the construction site for installation, so it is called a prefabricated panel. After the reinforcement, fill the hollow part with cement, knock off the board after it dries, and the rest is the prefabricated board. The prefabricated board has many uses in construction, such as the cement board covered on the ditch beside the road, and The cement slabs used as the heat insulation layer are all prefabricated slabs. There are horizontal joints and vertical joints between the prefabricated components in the concrete structure. The mechanical performance of the joints determines the overall performance of the structure. The joint structure of the existing precast concrete structures The measures generally seek to achieve the same effect as cast-in-place concrete, but because the joint surface of the new and old concrete at the joint is a weak link, it affects the mechanical performance, and is easy to crack, affecting normal use

[0003] The structure of traditional prefabricated slabs is relatively simple during production. In order to reduce the weight of components, holes are generally arranged in prefabricated components to form prefabricated hollow slabs. Compared with solid slabs, the bearing capacity of hollow slabs still has some shortcomings, and the position of hollow holes is relatively fragile. If the construction is not handled properly, it will easily cause floor cracking and water leakage when the building settles. The structural strength of the cement prefabricated board is low, and the building body using the cement prefabricated board is easily damaged.
