Abstract

The utility model belongs to a site-casting hollow floor structure of the construction field, in particular relating to a novel waterproof and fireproof light-weight filling body which is a fireproof sealed strengthened layer composed of a plastic light-weight expanded body wrapped with concrete, mortar and glass fiber grid cloth. The utility model is characterized in that a waterproof layer is wrapped on the fireproof sealed strengthened layer. The utility model has the advantages that the stress problem in each direction and the firing problem caused by electricity or gas welding during the construction engineering are solved; the utility model has good intensity, strong rigidness, light self-weight, low cost, low water absorption rate and zero construction breakage rate, which can meet various construction requirements; the waterproof performance additionally added to the utility model enables the smooth surface of the waterproof layer to facilitate the flowing of the concrete, so that various different moldings can be produced according to design requirements.

Description

New waterproof fire-proof light obturator

Technical field

The utility model belongs to the cast-in-situ hollow floor plate structure of building field, relates in particular to a kind of new waterproof fire-proof light obturator.

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 obturator to satisfy dead load light between the levels reinforcing bar of floor configuration, insulation and heat insulation effect.

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, while foot-operated the rubbing in when construction causes bellows seaming cracking easily; Simultaneously, electricity, gas welding are 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 casting quality; The water absorption rate on expanded material surface is generally bigger in addition; There is exactly the expandable filler of the sealant that is entwined with plastic adhesive tape inflammable again, likes accident on fire to occur especially in construction because of its surface, very impracticable.According to market demand the applicant invention and applied for when increasing building floor height and span, between the levels reinforcing bar of floor configuration, place the structure that light material is done filling, can alleviate dead load, play insulation, heat insulation effect, can satisfy the fireproof needs again.The back is subjected to client's favorable comment deeply though product of the present invention comes into the market, and the applicant is constantly improving its functional performance, adapts to the requirements at the higher level of market to its product.

The utility model content

The purpose of this utility model is: a kind of new waterproof fire-proof light obturator that has waterproofing course is provided on the basis of existing product functional performance.

For realizing that the technical scheme that the purpose of this utility model adopted is: a kind of waterproof fireproofing lightweight obturator, it is by this external fire proof seal enhancement Layer that is made of cement, mortar, fiberglass gridding cloth of wrapping up in of plastics light-weight foam, and it is characterized in that: hard-pressed bale is wrapped up in waterproofing course outside the fire proof seal enhancement Layer.

Above-mentioned waterproofing course is to be entwined or to apply waterproof agent by the sealing of marine glue adhesive tape.

The beneficial effects of the utility model are: the ignition issues that causes in the stressed problem that has solved all directions in the construction works and electricity, gas welding, its intensity is good, stiffness is big, from heavy and light, cost is low, water absorption rate is low, breakage rate is zero during construction, enough reaches the various requirement of construction; Increased water-proof function again; Make the waterproofing course smooth surface help concrete to flow, can produce 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 waterproof fireproofing lightweight obturator, 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 low alkali cement and fiberglass gridding cloth winding spread upon on the light-weight foam body.The fire proof seal enhancement Layer is stressedly 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; The function that waterproofing course has promptly played waterproof makes smooth surface help concrete flowing again, and 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 the utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.

Claims

1. new waterproof fire-proof light obturator, it is by this external fire proof seal enhancement Layer that is made of cement, mortar, fiberglass gridding cloth of wrapping up in of plastics light-weight foam, and it is characterized in that: hard-pressed bale is wrapped up in waterproofing course outside the fire proof seal enhancement Layer.

2. new waterproof fire-proof light obturator according to claim 1 is characterized in that: above-mentioned waterproofing course is to be entwined or to apply waterproof agent by the sealing of marine glue adhesive tape.
