Assembling method of gypsum evacuated mould

Abstract

The invention discloses an assembling method of gypsum evacuated mould, including paving a horizontal template at the bottom, determining positions of concrete beam and secondary girtstrip for assembling and fixing mould box, binding concrete beam and secondary girtstrip beam steel and embedding line pipes such as power and telecommunication and the like at the bottom of the secondary girtstrip. Floor plate beam steel is bound at the top of the gypsum evacuated mould box, concrete beam, secondary girtstrip and floor plate concrete are cast and vibrated, when concrete reaches designed age, thehorizontal template paved at the bottom is removed. Although connecting and assembling of mould box can be in multiple ways, the scheme shows that the assembling way of the invention is unique, the assembling method is combined with civil engineering construction, the mould box is embedded and fixed in steel concrete, no residual civil engineering construction procedure is produced, and the method is simple and feasible and is economic and practical. Contradiction of mould box production processing and architectural construction dimension requirement is solved, and the invention lays the foundation for the technology of making hollow floor system by promotion and application of concrete gypsum evacuated mould box in large scale.

Description

Technical field [0001] The invention relates to the field of building structures and building materials. Specifically, it is the method of assembling the plaster cavity mold. Background technique [0002] In the field of civil engineering, reinforced concrete is widely used due to its low cost and durability. For the floor system, it is usually composed of beams and slabs. The height of the beam is much larger than the thickness of the slab, and the beam should be exposed at the bottom of the slab to reduce the building clearance. When the span of the column network is large, in order to meet the rigidity requirements, the beam height needs to be increased to make the building clearance smaller. In order to overcome this defect and increase the rigidity of the floor, a multi-ribbed floor system appeared. Under the same span, the multi-ribbed beam has a smaller height, good rigidity and better stress. However, the shortcoming of multi-ribbed slabs is that the construction is ...

AI Technical Summary

Problems solved by technology

To meet the rib beam spacing requirements, the plane size of the mold box is too large, and there are considerable difficulties in processing prefabrication, handling, loading and unloading the mold box

To meet the requirements of the plane size of a single mold box, the spacing between ribs and beams is too small, the strength of reinforced concrete materials cannot be fully exerted, and the force is unreasonable, resulting in increased civil engineering costs; The design software cannot be calculated, and it is inconvenient for the majority of designers to master during promotion
