Abstract
The utility model discloses a lightweight composite filling member for a flame-retardant hollow floor slab, which comprises a lightweight foaming material body, wherein a cement mortar layer or a cement mortar layer with a reinforcing rib mesh is arranged outside the body; an inflammable lightweight foaming body is isolated from the outside by using the cement mortar layer or the cement mortar layer with the reinforcing rib mesh, so that a filling pipe fitting has less possibility of combusting, is safe and reliable, can effectively prevent fire from generating and provide the guarantee for the safe construction. The shape of the cross section of the body is elliptical or circular and square, thereby enhancing the flexibility of the use and broadening the application range. A chamfer or a circular angle is arranged at the corner around the body, so that the filling member has less possibilities of being bumped and damaged and the rejection rate and the waste of raw materials can be reduced.
Description
Technical field
The utility model belongs to building materials constructing technology field, and particularly a kind of flame retardant type cassette ceiling is with lightweight composite filled.
Background technology
In building, hydraulic engineering field, large span, large volume concrete structural and member are more widely used.In order to alleviate dead load and to strengthen concrete insulation, heat insulation, sound insulation, damping effect, be necessary more pre-buried lightweight filling members when concreting.Lightweight filling member instead of part concrete under the prerequisite that does not influence structural mechanical property, can alleviate dead load greatly, also can save building costs simultaneously.
At present, domestic several thin-walleds that are used for the concrete structure that have are filled pipe and lightweight filling member, its material therefor roughly is divided into: several big classes such as metal material, cement products, product of rubber and plastic, expanded perlite material, polyphenyl foam, separately pluses and minuses manifest gradually in the use.Metal bellows cost height, and when construction is easy to crack or damage such as welding hole occurs.The hollow section deadweight of being made by fragile materials such as high-strength cements is bigger, and the water absorption rate height reduces concrete intensity easily, and easily cracked.The hollow section cost of product of rubber and plastic is too high, easy scratching cracking when contacting with metal material.Though lightweight foam material can solve some problems of above-mentioned pipe fitting, but its material surface softness, the water absorption rate height, yielding under the external force effect, easily take place to wipe when contacting to bump the generation chip with the external world, pollute construction environment, reduce concrete pouring quality.Therefore, existing lightweight foam material filled tube is equipped with enhancement Layer and sealant structure, and overcoming self-defect, but the lightweight foam material of this kind filled tube and sealant all are combustible materials, and fire hazardous is buried disaster hidden-trouble to construction.
The utility model content
The purpose of this utility model provides special-purpose lightweight composite filled of a kind of nonflammable, safe and reliable flame retardant type cassette ceiling.
For achieving the above object, the technical solution of the utility model is: a kind of flame retardant type cassette ceiling comprises the lightweight foam material body with lightweight composite filled, and body is provided with the compo layer outward or has the compo layer of reinforcement net.
The shape of cross section of described body is oval or circular.
The shape of cross section of described body is square, and the corner around the body is provided with chamfering or fillet.
Compo layer or the compo layer that has a reinforcement net are located on this external stress surface, body and compo layer or have the compo layer coated outside refractory masses of reinforcement net.
Compared with prior art, the utility model has the advantages that:
1, outside body, be provided with compo layer or have the compo layer of reinforcement net, inflammable light-weight foam body is hedged off from the outer world, make filled tube nonflammable, safe and reliable, can effectively prevent the generation of fire, for safe construction provides safeguard.
2, the shape of cross section of body is oval or circular, square, has strengthened the flexibility of using, and the scope of application is wide.
3, the corner around the body is set to chamfering or fillet, makes that filling member is difficult for damaging, breakage, and the rate of reducing the number of rejects and seconds reduces wastage of material.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of the utility model embodiment one;
Fig. 2 is the cross-sectional structure schematic diagram of the utility model embodiment two;
Fig. 3 is the cross-sectional structure schematic diagram of the utility model embodiment three.
The specific embodiment
Embodiment one, special-purpose lightweight composite filled of cassette ceiling as shown in Figure 1, and it comprises lightweight foam material body 1, the shape of cross section of body 1 is oval.Be provided with the compo layer in body 1 outside or have the compo layer 2 of reinforcement net, compo layer or the compo layer 2 that has a reinforcement net are hedged off from the outer world inflammable light-weight foam body, make filled tube nonflammable, can effectively prevent fire incident.
The material that body 1 adopts is polystyrene foam plastics or Vestolit, polyurethane foam plastics.
Embodiment two, and be with the difference of embodiment one: the shape of cross section of body 1 is square, i.e. rectangle.Corner around the body 1 of square-section is provided with chamfering 4, and compo layer that body 1 is outer or the compo layer 2 that has a reinforcement net also corresponding setting have chamfering, makes that filled tube is difficult for damaging, breakage, the rate of reducing the number of rejects and seconds.
Embodiment three, be with the difference of embodiment two: compo layer or the compo layer 2 that has a reinforcement net are located on the stress surface of body 1 outside, at body 1 and compo layer or have the coated outside refractory masses 3 of the compo layer 2 of reinforcement net.
Be not limited to above-mentioned embodiment: the shape of cross section of body 1 also can be for circular or other are square, and for example square or rhombus, regular pentagon can also be the combined shaped of straight line and camber line; Fillet also can be arranged in corner around the square body 1.
Claims (4)
