Abstract
The utility model relates to an in-situ cast hollow floor slab structure, in particular to an inorganic fireproof foam filler pipe, which comprises a light foam body wrapped with a fireproof sealing and reinforcing layer. The utility model has the advantages that it has not only solved the force bearing at different directions as well as the problem of firing due to electric and gas welding during construction, but also it is of good strength, high rigidity, light dead weight, low cost, low moisture absorption, and zero breakage at construction. The utility model can meet various requirements from construction, be manufactured into various profiles as designed.
Description
Affiliated technical field
The utility model belongs to the cast-in-situ hollow floor plate structure, particularly a kind of inorganic fire-proof foamed filling tube.
Background technology
At building field, in order to reach the multifunction of use, intellectuality, large span, the structural system of large space are placed light material usually and are done and fill that to satisfy dead load light, insulation and heat insulation effect between the levels reinforcing bar of floor configuration.
At present domesticly developed several and be used for the filling pipe of concrete floor, its material therefor adopts metal material, cement products, rubber or plastic products etc. mostly, but have following deficiency when reality is used: 1, the metal bellows cost is higher, and foot-operated the rubbing during construction causes bellows seaming cracking easily, electricity simultaneously, gas welding is carried out operation and may be burnt hole if be close to bellows.2, the hollow section deadweight of making of fragile material such as high-strength cement is bigger, and water absorption rate is higher, when the load and cracked easily when stacking weight that withstands shocks.3, rubber or plastic hollow pipe cost are also higher, contact to cut to pieces easily with hard metal and bump cracking.4, directly fill with lightweight foam material, at first the surface of material own is softer, the excessive easy deformation of external force; Secondly hard metal scratches and is easy to generate the debris contamination construction environment, even has influence on concrete pouring quality; The water absorption rate on expanded material surface is generally bigger in addition: the expandable filler of the sealant that is entwined with plastic adhesive tape is arranged exactly again, and inflammable because of its surface, like accident on fire to occur especially in construction, very impracticable.So demand exploitation on the market urgently when increasing building floor height and span, between the levels reinforcing bar of floor configuration, place light material and do the structure of filling and can alleviate dead load, play insulation, heat insulation effect can satisfy the filling pipe that different clients use needs again.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes in the above-mentioned prior art, and providing a kind of has not only increased intensity but also can avoid the inorganic foamed lightweight of the band fire proof seal enhancement Layer of fire generation to fill pipe.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of inorganic foamed lightweight is filled pipe, it is characterized in that: it is made of this external fire proof seal enhancement Layer of wrapping up in of light-weight foam.
The fire proof seal enhancement Layer is by light burnt powder cement, and fiberglass gridding cloth constitutes.
The fire proof seal enhancement Layer is rectangle or circle, square, ellipse, rhombus, polygon.
The light-weight foam bulk material is polystyrene foam plastics or lightweight cellular plastic of polyvinyl chloride, polyurethane foam plastic.
The beneficial effects of the utility model are: not only solved the ignition issues that the stressed problem of all directions in the construction works and electricity, gas welding cause, and its intensity is good, rigidity is big, and from heavy and light, cost is low, and water absorption rate is low, and breakage rate is zero during construction.Can reach the various requirement of construction, can make various abnormal shapes according to designing requirement.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to the specific embodiment, structure, feature that foundation the utility model provides:
As Fig. 1-shown in Figure 5, a kind of inorganic foamed lightweight is filled pipe, and it is made of this external 1-2 of wrapping up in millimeter fire proof seal enhancement Layer of light-weight foam.The light-weight foam body can be polystyrene foam plastics or Vestolit, polyurethane foam plastics.The fire proof seal enhancement Layer is that light burnt powder cement and fiberglass gridding cloth winding spread upon on the light-weight foam body.The fire proof seal enhancement Layer is stressed around the light-weight foam body can resist general collision in the construction, trample, and repairs easily, and guarantees that material does not produce the debris contamination construction environment.When the light-weight foam body was soft, the fire proof seal enhancement Layer also had toughness, is not easy cracked.The fire proof seal enhancement Layer had not only increased intensity but also can avoid the generation of fire.
It can make various abnormal shapes (as Fig. 1-shown in Figure 5) according to designing requirement.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (4)
