Formwork for buildings, formwork component, cast-in-situ floor empty space and construction method thereof

Abstract

The invention relates to a formwork for buildings, a formwork component, a cast-in-situ floor empty space and a construction method thereof, and the formwork for the buildings comprises a formwork top surface made of hard material and support legs connected with the periphery of the formwork top surface. The formwork in the structure is simple in structure, convenient to assemble and use, short in assembly period and high in efficiency; furthermore, the formwork is made of the hard material, thereby having better waterproof and moisture-proof performances. When in site construction, a plurality of formworks can be mutually combined for use according to needs. The cast-in-situ floor empty space manufactured by adopting the formwork components is convenient to lay water, electricity and heating pipelines in an overhead cavity, thereby having good performances of ventilation, water resistance, moisture resistance, heat insulation and heat preservation. Due to the adoption of the formworkcomponents, the construction of the cast-in-situ floor empty space becomes simple, and the construction efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of overhead floors, in particular to a building formwork, a formwork assembly, an overhead floor on the ground of a cast-in-place building and a construction method thereof. Background technique [0002] In the existing architectural design and construction technology, in order to increase or block the air flow, to achieve the purpose of ventilation, moisture-proof, thermal insulation, laying pipes or cables when the floor is overhead, the waterproof layer on the floor and ground is used. Along the horizontal direction, use bricks to build the brick pier to the required height, place the prefabricated reinforced concrete slab on the brick pier, the brick pier extends along the vertical and horizontal directions, the brick pier is built with cement mortar, and the prefabricated reinforced concrete slab is imprisoned with mortar, Then use cement mortar to caulk the joints, so that an overhead layer is formed u...

AI Technical Summary

Problems solved by technology

Due to the use of prefabricated reinforced concrete slabs, the overhead floor of this structure has poor integrity and is prone to cracks, so its strength is low, the overhead efficiency is low, and it takes up a lot of space. It also has a long construction period, high labor intensity, and high construction efficiency. Low

In addition, the overhead layer of this structure has poor waterproof and moisture-proof effects and poor durability, and the overhead layer is made on top of the waterproof layer. The waterproof layer will break due to long-term pressure loss of elasticity, resulting in water leakage. Timely maintenance
