Description
Technical field
The present invention relates to the building Liang Wuliang is not provided between a kind of building structure and its construction method more particularly to a kind of column
The structure and its construction method of lid, are particularly suitable for building for needing space big such as market, freezer, warehouse etc..
Background technique
Traditional flat slab structure refers to that intercolumniation is not provided with beam, and superstructure is supported directly upon the bidirectional stress superstructure on column.
Its structural advantages is that good integrity, space are big, is widely used in such as warehouse on the building for needing space big, in addition,
The architectural construction height of arch without beam is smaller than rib-beam floor frame, is not limited by beam, and space layout is flexible, can effectively increase room
Internal layer is high, so that the useful space of architecture storey increases, while smooth bottom plate substantially improves daylighting, ventilation and sanitary condition.
But flat slab structure, due to not having beam, armoured concrete slab is directly supported on column, thus with identical colum network size
Rib-beam floor frame compare, plate thickness wants larger.For the calculating by punching bearing capacity and reduction plate for improving plate at capital
Usually bolumn cap will be arranged in capital in span.
Traditional flat slab structure is all to pour at the construction field (site), and due to not having beam, the bearing capacity of plate becomes larger, work
Ground site operation uncontrollable factor increases, and concrete strength not can guarantee, and needs to make a large amount of template, reinforcing bar binding
Site workload is also larger, thereby results in long construction period, quality is difficult to the problems such as unified, and because of construction material requested and people
Work is more and causes construction cost higher.
Summary of the invention
The technical problem to be solved in the present invention is that providing, one kind is easy for construction quickly, can greatly reduce Contraction in Site
The building flat slab structure and its construction method of amount.
The present invention solve above-mentioned technical problem the technical solution adopted is that, design a kind of building flat slab structure, comprising:
Column, the bolumn cap that the column periphery is set, the floor being supported on the column and its bolumn cap；The floor includes: position
Column strip at the bolumn cap, the intercolumniation strip between two neighboring column strip, be located at two neighboring intercolumniation strip it
Between middle strip；
The bolumn cap is prefabricated component, and the column strip of upper part is monolithic reinforced concrete structure, which is equipped with and reserves exposed steel
Muscle is connect with the reinforcing bar in the column and column strip；
