Description

A kind of cast-in-place concrete building roof structure utilizing NZ built-in support pipe die

Technical field

This utility model relates to a kind of with NZ built-in support pipe die for filling hollow floor slab material, and the cast-in-place concrete hollow building roof using dark beam and girt strip to combine belongs to building structure field in architectural engineering.

Background technology

In current architecture configuration, floor mainly uses the board-like superstructure of cast-in-situ concrete beam, this superstructure is limited by deck-molding, the clear height of floor, the setting in room, pipeline layout and decorations etc. are caused to be restricted, it is impossible to meet large space, large bay, the requirement of big load.In order to solve an above-mentioned difficult problem, occurring in that without the solid superstructure of beam, but this building cover board thickness of slab is relatively big, from great, cost is high, and structural behaviour is not fine, and according to the Force principle of floor, building cover board can use the form that filling hollow floor slab material combines with dark beam and girt strip.Filling hollow floor slab material mainly has at present: one, uses GBF, GRC glass fibre cement pipe, this material heavier-weight, is unfavorable for construction；Two, GZ macromolecule composite core formwork, but this material price is higher, it is impossible to produce preferable economic benefit；Three, NZ built-in support pipe die cast-in-situ hollow building roof technology is a kind of new architecture, the packing material that the polyethylene foam material strengthened by B0B adhesive tape parcel is made, it it is cored slab third generation obturator, being to substitute GBF, GRC glass fibre cement pipe and the optimal material of GZ macromolecule composite core formwork, it is low, from heavy and light and feature quick for installation that it has price.The template area of this version building cover board construction can reduce and reaches 20%, and all templates are surface plate end template, and difficulty of construction is low, and mould material cost and construction period are greatly reduced.This version sound-insulating and heat-insulating is effective, molding room is without furred ceiling, decrease furred ceiling finishing and the expense of furred ceiling renewal, increase floor clear height, can cut off in flexible arrangement room, alleviate dead load, improve building performance, reducing building comprehensive cost, and shorten the construction period, structural strength more can be leaned on safely.

Utility model content

The purpose of this utility model is overcome concrete solid floor and use GBF, GRC glass fibre cement pipe and GZ macromolecule composite core formwork as the deficiency of filling hollow floor slab material, a kind of cast-in-situ hollow building roof using NZ built-in support pipe die is provided, the problem that existing cast-in-place concrete solid floor exists can be solved, also GBF, GRC glass fibre cement pipe and the deficiency of GZ macromolecule composite core formwork can be improved, reduce building comprehensive cost, shorten the construction period.

The technical solution of the utility model is such that a kind of cast-in-place concrete building roof structure utilizing NZ built-in support pipe die, including floorslab concrete, at least one of which floor steel bar stress it is respectively provided with at the bottom of the Ban Ding of this floorslab concrete and plate, floorslab concrete is provided with hollow hole, hollow hole is filled NZ built-in support pipe die, being provided above Anti-floating reinforcing steel bar at NZ built-in support pipe die, Anti-floating reinforcing steel bar is connected with the floor steel bar stress at the bottom of plate by the anti-floating lacing wire of " S " type hook structure.

Further, in order to avoid there is the quality accident that floor floats when pouring floorslab concrete, dark beam design being positioned in floorslab concrete and girt strip pour floorslab concrete after being connected with floor steel bar stress again, finally floorslab concrete are carried out maintenance.

This utility model is such a kind of utilization with NZ built-in support pipe die to replace the part concrete in the middle part of floor, from the section along pipe direction, existence due to hollow hole, numerous little I-beam occurs in floor, forming one group of micro-space uniform dispersion general layout, different stress unit transmits floor gravity by dark beam, girt strip toward post or wall；Looking up in the side being perpendicular to pipe, there is the gap of 50mm, upper and lower configuration reinforcement in idle tube joint, it is ensured that the common stress of the energy of flange plate up and down that I-beam is more weak, defines reliable force transfer system.And use 3C12 Anti-floating reinforcing steel bar is set on pipe die top, Anti-floating reinforcing steel bar is connected with reinforcement by A6 " S " type drag hook, use pea gravel concreten, strengthen concrete slump, pour and reinforcement such as is vibrated at the measure at twice, solve hollow building cover NZ built-in support pipe die floating technical barrier.

This cast-in-place concrete building roof utilizing NZ built-in support pipe die of the present utility model, not only solve concrete solid floor and use GBF, GRC glass fibre cement pipe and GZ macromolecule composite core formwork as the problem of filling hollow floor slab material, also improve efficiency of construction, can significantly reduction of erection time, save engineering cost.
