Abstract
Disclosed is a combined core mould, which comprises an inner mould 1, a shrinking layer 2, an outer mould 3 and reinforcing ribs 4. The inner mould is made of high polymer material, the cavity is internally fully filled with fillers which can be air or liquid, a filling and discharging port 6 is arranged on the inner mould. The shrinking layer 2 is a cavity body made of elastic high polymer material and is integrally connected with the inner mould. The outer mould is made of high polymer material. The reinforcing ribs 4 are closed cavity structures made of high polymer material and are independent of the inner mould 1, the reinforcing ribs are internally fixed via high polymer fibers 5 and are fully filled with fillers which can be air or liquid, and each reinforcing rib is 4 equipped with a filling and discharging port 7. The combined core mould can be in the shape of a circle, a regular polygon, a rectangle and an ellipse.
Description
Technical field:
The utility model relates to a kind of constructional materials structure, is specifically related to a kind of cast-in-situ reinforced concrete with becoming pole.
Background technology:
At present in the process of construction in large-scale house, traditional prefabricated hollow floor seldom uses because of himself heaviness, installation, transportation inconvenience.The substitute is the floor that adopts cast-in-place technology site operation cast.For the dead load that alleviates floor, reduce steel bar concrete consumption, reach soundproof effect preferably, improve structure mechanical property, improve building supporting capacity, reduce the deflection of structure, in cast-in-situ reinforced concrete, adopted core to reach the purpose of the floor of finding time.At present commonly used have disposable filling cores such as paper tube, plastic pipe, metal bellows, pipe of cement, GRC pipe.Above-mentioned core all can not well come into operation because weight is big, price is high, easily fragmentation and complex manufacturing in the intensity difference, construction.Therefore seek a kind of in light weight, with low cost, intensity is high, it is broken to be difficult for. produce simple core and just become current problem demanding prompt solution.
The utility model content:
The utility model is at the problem that prior art exists, and designs a kind of drawing out type composite core formwork of simple in structure, intensity is high, it is broken to be difficult for, cost is low, easy for installation cast-in-place reinforced concrete filling.
In order to solve the problems of the technologies described above, the solution that the utility model proposes is:
This composite core formwork comprises internal mold, shrinkage layer, external mold and ribs.Internal mold is the airtight cavity of being made by macromolecular material; Its inside is full of filler, and the material of filler can be gas, liquid; Leave the injection outlet opening on the internal mold.
Described shrinkage layer is the cavity of being made by the elasticity macromolecular material, and is connected as a single entity with internal mold.
Described external mold is the cavity that is independent of shrinkage layer and internal mold that macromolecular material is made.
Described ribs is a closed chamber body structure of being made and be independent of internal mold by macromolecular material; Its inside is fixed with the macromolecular fibre silk, and is full of filler, and the material of filler can be gas, liquid; Leave the injection outlet opening on the ribs.
Described composite core formwork shape can be circle, regular polygon, isosceles trapezoid, ellipse.
The novel advantage of this use is to have adopted that disposable core weight such as the more traditional paper tube of internal mold, shrinkage layer, external mold and the ribs made by macromolecular material, plastic pipe, metal bellows, pipe of cement, GRC pipe are lighter, intensity is higher, it is broken to be difficult in the construction, cost is lower, make things convenient for onsite moving, installation and construction, effectively accelerating construction progress, saving national resources.Core is selected to adopt circle, regular polygon, isosceles trapezoid, ellipse according to the needs of load simultaneously, can further guarantee the bulk strength of core.
Description of drawings:
Fig. 1 is the generalized section of composite core formwork;
Fig. 2 is the generalized section of composite core formwork;
Fig. 3 is injection outlet opening 6 generalized sections of composite core formwork;
Fig. 4 is injection outlet opening 7 generalized sections of composite core formwork
Fig. 5 is the structural profile schematic diagram of composite core formwork;
The specific embodiment:
As shown in Figure 1, this composite core formwork mainly is made up of internal mold 1. shrinkage layers, 2. external molds 3 and ribs 4 four parts of circle.Internal mold 1 is airtight cavity body structure; And in cavity, being full of filler, the material of filler is gas, liquid; And leave and inject outlet opening 6.Described shrinkage layer 2 is to make cavity by the elasticity macromolecular material, and is connected as a single entity with internal mold 1.Described external mold 3 is made the cavity that is independent of shrinkage layer 2 and internal mold 1 for macromolecular material.Described ribs 4 is closed chamber body structures of being made and be independent of internal mold 1 by macromolecular material, and it is inner fixing with macromolecular fibre silk 5; And being full of filler, the material of filler can be gas, liquid; Leave on the ribs and inject outlet opening 7.
The shape of composite core formwork also can be regular polygon, isosceles trapezoid, oval owing to these shapes all can be imagined in addition, so accompanying drawing is not providing one by one.
Claims (5)
