Abstract
The invention discloses a fiber concrete-profiled steel sheet composite floor which has low cost, simple construction and light self-weight. Compared with the traditional concrete-profiled steel sheet composite floor, the fiber concrete-profiled steel sheet composite floor is characterized in that fiber is blended into common concrete to replace the original surface crack resistant reinforcing steel bars, distribution reinforcing steel bars and bottom layer reinforcing steel bars, together with the special structure of bottom layer profiled steel sheet, thus completely saving the placement of reinforcing steel bars, reducing construction cost, facilitating construction and lightening the self-weight of the floor. The fiber concrete-profiled steel sheet composite floor can be widely used in the field of constructional engineering structure.
Description
Technical field
The present invention relates to construction engineering technical field, relate in particular to a kind of fibre concrete-profiled steel sheet combination floor for building.
Background technology
In recent years, along with the development of highrise building, concrete-profiled steel sheet combination floor obtains promotion and application day by day.Concrete-profiled steel sheet combination floor is a kind of ten minutes reasonable structure form, it can be by its residing position of each building block and characteristics, give full play to steel tension and the good advantage of concrete compressive property, and have good seismic resistance, workability, during this structure is widely used in building both at home and abroad at present.As shown in fig. 1, a kind of combining form for existing concrete-profiled steel sheet combination floor, concreting is in the profiled sheet top, be horizontally arranged with distribution reinforcement in the concrete top section, be vertically arranged with surface layer cracking resistance reinforcing bar, be provided with bottom layer of the reinforcing steel in concrete underclad portion longitudinal separation, profiled sheet can be used as the permanent template of cast-in-situ concrete, so just save operation such as installation and stripping in the construction, thereby saved time and labour.Owing to need be provided with reinforcing bar and surface layer cracking resistance reinforcing bar in the concrete top section in the combinations thereof form, vertically assist in the concrete underclad portion and be equipped with bottom layer of the reinforcing steel, increased building costs greatly, increased the construction working amount, also increased the weight of floor itself.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides that a kind of cost is low, construction is simple, from the tencel concrete-profiled steel sheet combination floor of heavy and light.
The technical solution adopted in the present invention is: the present invention includes fibrous concrete and profiled sheet, described profiled sheet is arranged on the bottom, fibrous concrete has been built in described profiled sheet top, described fibrous concrete is that evenly to disperse to mix fiber in original ordinary concrete formed, and described fiber is steel fibre or synthetic fibers.
The base plate top of described profiled sheet is arranged at intervals with the del type rib of end opening closure or semi-closed.
The base plate top of described profiled sheet is arranged at intervals with cross section and is circular or polygonal closo rib.
The vertically upright rib of position formation " Γ " shape is interlocked between the described profiled sheet.
The invention has the beneficial effects as follows: the present invention compares with existing concrete-profiled steel sheet combination floor, bar construction cancellation with the concrete part, replace by fiber, add the effect that fiber mainly plays cracking resistance at concrete, under the situation that reaches same intensity and fire-resistant requirement, saved steel greatly, reduced building costs, reduce the weight of floor self, reduced the construction working amount on the certain degree, obtained good economic benefit.

The specific embodiment
Embodiment one:
As shown in Figure 2, the present invention includes fibrous concrete and profiled sheet, described profiled sheet is arranged on the bottom, described fibrous concrete has been built in described profiled sheet top, described fibrous concrete is that evenly to disperse to mix fiber in original ordinary concrete formed, and described fiber is steel fibre or synthetic fibers.Compare ordinary concrete-profiled steel sheet combination floor, can save surface layer cracking resistance reinforcing bar and the distribution reinforcement and the bottom layer of the reinforcing steel on concrete upper strata, the base plate top of described profiled sheet is arranged at intervals with the del type rib of end opening closure or semi-closed, described del type rib both can replace original bottom layer of the reinforcing steel, also can play effect such as cabling or placement water pipe in its wedge shape cavity, and can reach respective strengths and fire-resistant requirement equally after using fibrous concrete.With the steel fibre is example, the match ratio design of steel fibrous concrete, should be by the strength grade requirement of structure design, according to the fiber dispersion in the steel fibrous concrete mixture, mixture workability and sclerosis properties of Steel Fibre Reinforced Concrete as one or several performance requirements such as (resistance to compression, anti-folding, shearing resistance) intensity, bent toughness, cracking resistance, shock resistance, anti-fatigue performance and antidetonation, antiknocks, determine volume content of steel fibers by test and existing engineering experience.
Embodiment two:
Compare with embodiment one, difference is through the type rib structure on the top of the base plate of the integrated profiled sheet of roll compacting different, as shown in Figure 3, the base plate top of described profiled sheet is arranged at intervals with cross section and is circular or polygonal closo rib, and further feature is identical with embodiment one.
Embodiment three:
In the present embodiment, the dual-side of the profiled sheet of fibrous concrete bottom is vertical flanging, and the position that is interlocked between two profiled sheets forms the vertically upright rib of " Γ " shape, and as shown in Figure 4, further feature is identical with embodiment one.
The present invention is widely used in the building engineering structure field.
Claims (4)
