Abstract
The present invention relates to a steel skeleton concrete cast-in-situ hollow floor slab and its construction method. It is characterized by that the interior of cast-in-situ reinforced concrete contains core-drawn and hole-formed cavity and steel skeleton, and its construction method includes the following steps: mounting steel skeleton, placing its two ends on the bearing wall (column), form erecting, laying press steel plate or removable form, laying reinforcement, embedding core mould, fixing and positioning, pouring and vibrating concrete, curing, and when the concrete is hardened to proper strength, drawing aut core mould and removing form. Said invention possesses advantages of large bearing capacity, good aseismic behavior and convenient construction, etc..
Description
The invention belongs to a kind of steel bar reinforced hollow concrete roof cast-in-situs, be specially adapted to the cast-in-situ floor of highrise building and longspan structure.
At present, steel bar reinforced hollow concrete roof cast-in-situs mostly adopts ordinary reinforced concrete structure and prestressed reinforced concrete construction, and its supporting capacity, anti-seismic performance, difficulty of construction more and more can not satisfy the requirement of highrise building and longspan structure development.
Purpose of the present invention just provides that a kind of supporting capacity is big, anti-seismic performance good and the in-situ and deposited hollow reinforced concrete roof of easy construction and job practices thereof.
In-situ and deposited hollow reinforced concrete roof of the present invention, its characteristics are that the cast-in-situ reinforced concrete inside of making contains the cavity and the reinforcing bar of core-drawing pore-creating; Described reinforcing bar can be arranged on light and shade beam inside or intralamellar part or other position; Described cavity is the cavity that forms behind the core in the Cast-in-place concrete setting and harden is extracted out to suitable intensity; Described reinforcing bar is " L ", " I ", " II ", " ", " steel part of different shapes such as [" that shaped steel or other steel are made.
The job practices of in-situ and deposited hollow reinforced concrete roof of the present invention is:
(1) reinforcing bar is installed, its two ends are placed on the load bearing wall (post);
(2) formwork is laid profiled sheet or removable template, and is when laying profiled sheet as template, that profiled sheet and reinforcing bar is affixed;
(3) lay reinforcing bar;
(4) pre-buried core with the core stationary positioned, overcomes the unsteady and construction displacement of concrete core mould, guarantees the thickness of the outer concrete of cavity;
(5) cast vibrate concrete, maintenance, extract core at the concrete setting and harden out to suitable intensity.
(6) remove removable template.Can out the outlet sealing of core will be extracted in case of necessity.
The present invention has advantages such as supporting capacity is big, anti-seismic performance good, easy construction owing to adopted reinforcing bar and non-core-drawing pore-creating structure, is specially adapted to the hollow building cover of highrise building and longspan structure.
The invention will be further described below in conjunction with description of drawings:
Fig. 1 is the perspective view of the embodiment of the invention one.
Fig. 2 is the perspective view of the embodiment of the invention two.
Fig. 3 is the perspective view of the embodiment of the invention three.
Fig. 4 is the perspective view of the embodiment of the invention four.
Shown in Fig. 1-4, the present invention is made up of reinforcing bar 1, concrete 2, cavity 3, reinforcing bar 4.Among the embodiment that Fig. 2 provides, described reinforcing bar 4 places under the reinforced concrete hollow floorslab by profiled sheet 5, forms bright beam hollow building cover.The embodiment that Fig. 1,3,4 provides, described reinforcing bar 4 is embedded in the steel bar concrete.Among Fig. 1 reinforcing bar 4 vertically and the geometric center lines of cavity 3 in the same way.Reinforcing bar 4 is vertically vertical with the geometric midline of cavity 3 among Fig. 3,4.Among the embodiment of Fig. 4, have profiled sheet 5 under its hollow building cover, this structure is convenient to construction and is made, the profiled sheet 5 permanent reservations that formwork is used.
In the above-described embodiments, reinforcing bar 4 all can adopt typing L, I, [, type shaped steel, also can adopt the non-type deformed steel or with steel material welding, the special-purpose shaped steel that is rolled into.In addition, described cavity 3 is the cavity of the back pore-forming of loosing core.

2, in-situ and deposited hollow reinforced concrete roof according to claim 1 is characterized in that reinforcing bar can be arranged in the steel bar concrete of light and shade beam inside or hollow building cover or other position;
3, in-situ and deposited hollow reinforced concrete roof according to claim 1 is characterized in that cavity is the cavity that forms behind the core in the Cast-in-place concrete setting and harden is extracted out to suitable intensity;
4, in-situ and deposited hollow reinforced concrete roof according to claim 1.It is characterized in that reinforcing bar is " L ", " I ", " II ", " ", " steel part of different shapes such as [" that shaped steel or other steel are made.
5, a kind of job practices of in-situ and deposited hollow reinforced concrete roof is characterized in that:
(1) reinforcing bar is installed, its two ends are placed on the load bearing wall (post);
(2) formwork is laid profiled sheet or removable template, and is when laying profiled sheet as template, that profiled sheet and reinforcing bar is affixed;
(3) lay reinforcing bar, install in the concrete pre-buried;
(4) pre-buried core with the core stationary positioned, overcomes the unsteady and construction displacement of concrete core mould, guarantees the thickness of the outer concrete of cavity;
(5) cast vibrate concrete, maintenance, extract core at the concrete setting and harden out to suitable intensity.
(6) remove removable template.
