Description

Anti-seismic prefabricated floor and floor antidetonation splicing construction
Technical field
It is to be related to a kind of anti-seismic prefabricated floor and utilize the floor more specifically the invention belongs to technical field of buildings Antidetonation splicing construction.
Background technology
Floor is that if house vertical direction is divided into dried layer, and the vertical loads such as people and furniture and floor deadweight are passed through Wall, beam or post are transmitted to basis.Material as used in it can be divided into wood floor, brick arch floor, reinforced concrete floor and steel lining Several forms such as the floor of plate load-bearing.
Reinforced concrete floor is made jointly using concrete and rebar.This floor is firm, durable, and rigidity is big, intensity Height, fire protecting performance is good, and current application is commonplace.It can be divided into in-situ reinforced concrete slab and assembled steel by construction method The major class of bar concrete floor two.
In-situ reinforced concrete slab is generally solid slab, and cast-in-situ floor also often pours together with Cast-in-situ Beam, is formed existing Pour beam slab.Floor is made according to actual conditions are integrated poured in cast-in-situ floor, and this floor strength is more than precast floor slab, is sent out in earthquake During life, floor is not easy part and fallen down, and causes injures and deaths probability smaller, but its work progress is complex, have impact on construction Efficiency, and cost is higher, and a large amount of templates are used in building course, and the cost of form shore just accounts for the ratio of floor totle drilling cost It is larger, need site operation to pour into a mould.
Assembled steel bar concrete floor, typically all being stretched at plate end has reinforcing bar, the concrete cementation of fissures is used after on-site consolidation, to add Strong globality.It is that floor is divided into some components of beam, plate using such floor, it is good in precast plant or job site pre-production, Then installed.Its advantages of is can to save template, improves working condition when making, accelerating construction progress;It is but overall Property it is poor, and need certain rising to re-mount equipment.
As building industrialization improves, particularly largely prestressed concrete earth process, prefabricated reinforced concrete floor are used Using will be more and more extensive, can be divided into according to its construction following several:
Solid panel:Solid panel makes simple, saving template, suitable for the less position of span, such as corridor plate, landing slab Deng.For this solid panel from great, poor seismic behavior, soundproof effect is poor, more using material.
Cored slab:Upper and lower surface is smooth, sound insulation and good heat-insulation effect, is widely used in the superstructure and roof system of civil buildings In.But the solid slab and cored slab used at present, do not connect between two adjacent plates so that building integrally stretching degree is not Height, in earthquake and other accidents, current precast floor slab is easier to cause casualties.
The content of the invention
