Abstract
The utility model provides a removable square-box core mould, which includes a shell body, a strengthening rib, a port, and an installation positioning device. The structure differing from the prior structure is that the shell body is made of polymer material and is made into a hermetical cavity body, and is provided with a gas (or liquid) inpouring (discharging) opening, gas (or liquid) is full of the shell body. The strengthening rib is made of polymer material and is made into a hermetical cavity body separating from the shell body, and gas (or liquid) is full of the inside of the strengthening rib. The port is made of polymer material, so that the gas (or the liquid) is sucked out for drawing the square-box core mould out after the pouring on the building cover is finished. The positioning device is made of polymer material, and includes a supporting table arranged on the bottom of the square-box core mould, and polymer material threads for fixing the square-box core mould. The removable square-box core mould has the advantages that: the shell body, the strengthening rib, the port, and the installation positioning device made of polymer material are adopted, compare with the traditional cement square-box core mould and the bamboo-core core module, the weight is more light, the cost is low and the intensity is high, the break does not exist, the installation and the construction are convenient, and the progress rate of construction can be effectively improved.
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 filling core.
Technical background:
In the process of construction of large-scale building construction, traditional prefabricated hollow floor is because of himself heaviness at present, and the installation and transportation inconvenience is seldom used.The substitute is and adopt the field erected cassette ceiling of cast-in-place technology.In order to alleviate the dead load of floor, reduce the consumption of steel bar concrete, reach soundproof effect preferably simultaneously, improve structure mechanical property, improve building supporting capacity, reduce the deflection of structure, in cast-in-situ reinforced concrete, inserted the square box core member of some drawing out type.
The square box member that cement square box core at present commonly used and bamboo core etc. form cavitys is big owing to own wt, price is high, easy reason such as fragmentation and complex manufacturing in the intensity difference, construction, all can not well come into operation.Therefore seek a kind of in light weight, cost is low, intensity is high, not broken, produce simple square box member and just become current problem demanding prompt solution.
The utility model content:
The utility model is at the problem that existing technology exists, design a kind of in light weight, simple in structure, intensity is high, not broken in construction, cost is low, the drawing out type square box internal mold of easy for installation, the cast-in-place reinforced concrete filling that can realize large-scale production.In order to solve the problems of the technologies described above, the solution that the utility model proposes is:
This drawing out type square box core comprises housing, ribs, port and mounting and positioning device.Different with existing structure is that described housing is to be made by macromolecular material, is full of filler in the housing, and the material of filler can be gas, liquid; Leave filler on the housing and inject outlet opening, so that after construction is finished, take out the gas in the housing.
Described ribs is made by macromolecular material and is independent of the airtight cavity of housing, and is full of filler in inside, and the material of filler can be gas, liquid.
Described port is to be made by macromolecular material, and with housing be one.
Described positioner is to be made by macromolecular material, and is connected as a single entity by macromolecular material silk and housing.
The tangent plane shape of described drawing out type square box core can be circle, regular polygon.
Advantage of the present utility model is to have adopted housing, ribs, port and the mounting and positioning device of being made by macromolecular material.More traditional cement square box core, bamboo core core construction weight is lighter, cost is low, intensity is high, not broken, be convenient to install and construction, can effectively improve construction speed.
Description of drawings:
1 drawing out type square box of accompanying drawing core generalized section
2 drawing out type square boxes of accompanying drawing core structural representation,
The specific embodiment:
This drawing out type square box core mainly is made up of housing 1, ribs 2, port 3 and mounting and positioning device 4 four parts.Housing 1 is the airtight cavity of being made by macromolecular material, and at inner blanketing gas or liquid, and on housing 1, leave gas or liquid discharge port 3, so that behind the floor casting complete, extract the internal gas or the liquid of square box core out, take out the square box core.Ribs 2 is the independence made by macromolecular material and the airtight cavity of housing, its inner gassy or liquid, and be fixed in the housing to strengthen the intensity of square box core, mounting and positioning device 4 is brace tables that are positioned at the housing below of being made by macromolecular material, and be fixed together by macromolecular material silk and housing, it mainly is the distance that guarantees between core and the end muscle, and the preformed hole on it is convenient to drawing out type square box core is fixed on the soffit formwork, to reach the effect of anti-floating.
The tangent plane shape of drawing out type square box core can be circle, regular polygon in addition.
Claims (6)
1. drawing out type square box core, it comprises housing, ribs, port and mounting and positioning device, and housing is to leave the airtight cavity that injects outlet opening, and it is characterized in that: described housing is to be made by high one's share of expenses for a joint undertaking material, be full of filler in the housing, the material of filler can be gas, liquid; Leave filler on the housing and inject outlet opening, so that after construction is finished, take out the filler in the housing.
2. drawing out type square box core according to claim 1 is characterized in that: described ribs is the independence made by macromolecular material and the airtight cavity of housing, and portion is full of filler within it, and the material of filler can be gas, liquid.
