Abstract

The invention discloses a concrete floor slab with foamed concrete and relates to concrete floor slab construction, aiming to solve the problems that a concrete floor slab is heavy in weight, limited in application span and the like. The concrete floor slab comprises a lower ordinary reinforced concrete layer, a middle foamed concrete layer and an upper ordinary reinforced concrete layer. The middle foamed concrete layer is located above the lower ordinary reinforced concrete layer, and the upper ordinary reinforced concrete layer is located above the middle foamed concrete layer. The lower ordinary reinforced concrete layer, the middle foamed concrete layer and the upper ordinary reinforced concrete layer are integrally bonded to form a common stress-bearing component. The lower ordinary reinforced concrete layer is a cast-in-situ concrete slab or a prefabricated composite concrete slab, and the concrete floor slab with the foamed concrete is formed. The concrete floor slab is light in weight, low in construction cost, convenient to construct and capable of forming a large-span floor and roof.

Description

A kind of concrete floor that has foam concrete

Technical field

The present invention relates to a kind of construction floor technology, particularly a kind of concrete floor that has foam concrete.

Background technology

Alleviate flooring, roofing weight is the difficult problem on building circle always.

It is a double-edged sword that concrete slab increases profile height, although can increase supporting capacity, but concrete gravity increases too many, therefore general concrete floor or roof panel height are between lOOmm~150mm, in the time that flooring large span need to increase FFL, often just need to make primary-secondary beam structure, or in plate, installation mold forms cassette ceiling.Primary-secondary beam structure formwork trouble, amount of concrete is still large, and cost or high, increases structural weight per square meter very unfavorable to highrise building, seismic areas building, and this is restricted the application span of concrete slab.Also useful prestressed concrete, solve the excessive problem of large span floor amount of deflection, but in the time catching fire, prestressing force is lost with regard to danger close.

The use span, the convenient construction that how to alleviate roofing, flooring weight, increase concrete slab, reduce cost

It is more than problem to be solved by this invention.

Summary of the invention

The object of this invention is to provide a kind of concrete floor that has foam concrete, to solve the problem described in background technology.

A kind of light thermal insulation roof board of the present invention or floor, described a kind of concrete floor that has foam concrete, it comprises bottom ordinary reinforced concrete layer, middle part foam concrete layer, top ordinary reinforced concrete layer; Described middle part foam concrete layer is positioned at above the ordinary reinforced concrete layer of bottom, and top ordinary reinforced concrete layer is positioned at above the foam concrete layer of middle part; Between bottom ordinary reinforced concrete layer, middle part foam concrete layer and top ordinary reinforced concrete layer, be bonded as one layer by layer, form a common primary structure member;

Described bottom ordinary reinforced concrete layer is cast-in-situ concrete or is prefabricated superimposed concrete slab, the concrete that described top ordinary reinforced concrete layer is cast in situs, the foam concrete that middle part foam concrete layer is cast in situs, forms a kind of concrete floor that has foam concrete.

A kind of light roof of installing with light heat insulating board of the present invention or the difference of flooring and prior art are:

A kind of concrete floor that has foam concrete of the present invention is unexistent in the design of existing concrete floor, mounting technique.

Technique effect of the present invention:

Suppose have the concrete floor of foam concrete gross thickness 200mm, in ask and in lOOmm thickness, select density 500~900kg/m 3foam concrete, its deadweight is lower than the ordinary concrete floor of thickness 150mm or approach.But the concrete floor that has foam concrete of 200mm thickness is because its depth of section is high, and the bending resistance arm of force is large, and quantity of reinforcement is little, can reduce construction stage energy consumption, reduce cost, be particularly applicable to the demand of large span floor.On the ordinary reinforced concrete layer of bottom, build that foam concrete construction is very convenient, speed is fast, cost is low, can be applicable to large span floor or flat roof deck plate.

Accompanying drawing explanation

Figure l is a kind of concrete floor profile construction schematic diagram that has foam concrete of the present invention, and the concrete floor of foam concrete and whole the watering of the beam of major structure of construction are integrated;

Fig. 2 is a kind of concrete floor profile construction schematic diagram that has foam concrete of the present invention, and foam concrete is positioned at the beam top of major structure of construction.

Figure l, Fig. 2 dotted line in floor represents the post of major structure of construction.

Embodiment: see Fig. 1, a kind of concrete floor that has foam concrete of present embodiment, it is made up of bottom ordinary reinforced concrete layer 1, middle part foam concrete layer 2, top ordinary reinforced concrete layer 3: described middle part foam concrete layer 2 is positioned at above bottom ordinary reinforced concrete layer 1, and top former times, logical reinforced concrete floor 3 was positioned at above middle part foam concrete layer 2; Between bottom ordinary reinforced concrete layer 1, middle part foam concrete layer 2 and top ordinary reinforced concrete layer 3, be bonded as one layer by layer, form a common primary structure member;

Described bottom ordinary reinforced concrete layer 1 is cast-in-situ concrete or is prefabricated superimposed concrete slab, the concrete that described top ordinary reinforced concrete layer 1 is cast in situs, the foam concrete that middle part foam concrete layer 2 is cast in situs, forms a kind of concrete floor that has foam concrete.

Middle part foam concrete layer 2 can be equal densities, or in the density difference of different parts.

For guaranteeing to be bonded as one layer by layer between bottom ordinary reinforced concrete layer 1, middle part foam concrete layer 2 and top ordinary reinforced concrete layer 3, can brushing interfacial agents on bonding interface.Interfacial agents can be plain-water slurry, or also adds water soluble polymer bonding adhesive in plain-water slurry, as polyacrylate dispersion, vinyl acetate. the interfacial agents of vac emulsion or dry powder preparation.

A kind of concrete floor that has foam concrete of the present invention can be integrated with whole the watering of the beam of major structure of construction, see figure l, while building foam concrete, side at concrete beam should be provided with template, after beam inner concrete condenses, remove side template, then build foam concrete, avoid the foam concrete of building to enter in concrete beam.Foam concrete also can not enter concrete

A kind of concrete floor that has foam concrete of the present invention also can be positioned on the fine strain of millet of major structure of construction, with beam not whole watering be integrated, see Fig. 2.
