Composite block equipped with metal net and/or reinforced bar plasterer, and its bonding construction method

Abstract

The invention relates to a composite member provided with a metal gauze and / or a reinforced coating, which relates to a building composite member and aims to solve the problems of heavy weight of a concrete floor and so on. The composite member comprises a cement mortar layer, a core layer, and the metal gauze and / or reinforcing steel bars in the cement mortar layer, wherein, the cement mortar layer is arranged outside the core layer. The primary cementation is as follows: an interface agent is coated on the surface of the core layer, and the core layer is bonded with a cement mortar coating into a whole when the interface agent is wet. The secondary cementation is as follows: after the interface agent coated on the core layer for the first time is dried, the interface agent is coated on the core layer for the second time, and the core layer is bonded with the cement mortar coating into a whole when the interface agent coated for the second time is wet. The tertiary cementation is as follows: the interface agent is coated on mutual seams of the massive or platy core layers, and the core layers coated with the interface agent are bonded with each other for assembly; or the interface agent is coated on walls of holes passing through the core layers, and the cement mortar layer running through the core layers is bonded with the walls of the holes in the core layers through the wet interface agent. The composite member has the advantages of lightening of the weight of the building member, good heat-insulating property, low manufacturing cost and convenient construction.

Description

technical field [0001] The invention relates to a building composite element. Background technique [0002] At present, in construction, reinforced concrete is mainly used as floor slabs, roof slabs, concrete walls, and masonry walls. These materials have high density, and the long-span concrete floor slabs are thick and heavy. The large section size increases the building height, which is unfavorable for earthquake resistance and increases the cost. Therefore, there are cast-in-place hollow slabs installed with various formwork construction inside the concrete slab, which can reduce the weight of the long-span concrete slab. However, in some project locations, there is no manufacturer to provide formwork in the cast-in-place hollow slab, or when the thickness of the slab is not very large, the weight reduction ratio is small and it is not suitable to use the hollow slab. [0003] At present, there is no roof panel with good comprehensive performance as the roof panel on t...

Problems solved by technology

However, in some project locations, no manufacturer provides formwork in the cast-in-place hollow slab, or when the thickness of the slab is not very large, the weight reduction ratio is small, and it is not suitable to use the hollow slab

[0003] At present, there is no roof panel with good comprehensive performance as the roof panel on the steel roof truss or steel beam. The weight of the concrete roof panel is too heavy, which greatly increases the steel consumption of the steel roof truss or steel beam, which makes the roofing projects of many steel structure buildings The cost is very high, and often cannot meet the requirements of heat preservation and energy saving
