Description
Technical Field
The utility model belongs to the technical field of bridge engineering construction equipment, concretely relates to surrounding type steel centre form system.
Background
Bridge centre form bridge mandrel come-up problem is one of the technical problem in the puzzlement construction in precast beam board concrete pouring process, then can make the roof plate not enough and roof reinforcing bar protective layer can surpass standard requirement light then, then can lead to the beam slab to be unable to use, extravagant artifical material heavy.
The type of the internal mold of the precast beam slab used in China at present is as follows:
the steel mould is made of steel plates, has high strength, is not easy to float upwards or deform, is widely applied in the construction process of the prior precast beam slab, and has the defects of difficult disassembly, large occupied space during storage and high labor cost.
The inflatable capsule core mould (the existing inflatable core mould has serious floating and complex maintenance, and is not generally recommended at present) is mostly made of rubber, is convenient to disassemble in use, and saves storage space. But the use is extremely unstable, and the influence on the self requirement of the bridge is large due to the size of the inflated pressure, the thickness of the material per se, the distance between the air bag fixing ribs, the nonstandard bridge internal mold structure and the like.
The wood pattern is made of wood boards, is easy to process and produce, the quality of the wood pattern board is related to the quality of concrete engineering, and the wood pattern board has the defects that the wood pattern board is easy to deform after being turned over for several times, is improper to use, is easy to bulge and crack, is difficult to control the thickness and the like, and therefore cracks can be caused to occur at a certain part.
The disposable bridge core mold adopts a polystyrene foam internal mold, the material of the core mold is very light, the buoyancy generated in the concrete pouring process is very large, and the floating control measure is extremely important.
Disclosure of Invention
The utility model discloses to the dismantlement difficulty that exists in the current prefabricated plate centre form, cause the damage scheduling problem to the bridge concrete, provide an environmental steel centre form system.
The utility model adopts the following technical scheme:
the utility model provides a surround type steel centre form system, includes that the centre form that matches with the roof beam slab supports and is located the centre form and supports the fixing device in the outside, wherein, the centre form supports the steel sheet that includes a plurality of head and the tail concatenations, and the surface of the link of steel sheet is equipped with the trompil that plays the regulating action, is equipped with the bolt that plays the fixed action in the trompil, fixing device includes a plurality of square steels of the adjacent range of surface that supports along the centre form, the fixing device outside is equipped with the ribbon that plays the fixed action.
The length direction of the square steel is the same as that of the beam plate.
And a plastic film layer is arranged on the outer surface of the fixing device.
The utility model has the advantages as follows:
the utility model discloses simple structure, reducible intensity of labour, the security is high, guarantees construction safety, improves the construction efficiency, the utility model discloses an interior support system adopts shaped steel to encircle the concatenation as the skeleton that the template supported, the outside, and the reuse ribbon ligature lays plastic film in the outside, and traditional steel design centre form or gasbag are replaced to this method, conveniently demolish, can reduce the damage to the concrete to minimum. The template system saves manpower, is easy to operate, and has high efficiency and good construction quality.
Drawings
Fig. 1 is a schematic structural view of the present invention;
wherein: 1-internal mold supporting; 2-opening a hole; 3-a bolt; 4-a fixing device; 5-plastic film layer.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model provides a surround type steel centre form system, includes that the centre form that matches with the roof beam slab supports 1 and is located the centre form and supports fixing device 4 in the 1 outside, wherein, centre form supports 1 and includes the steel sheet of a plurality of head and the tail concatenations, and the surface of the link of steel sheet is equipped with trompil 2 that plays the regulating action, is equipped with the bolt 3 that plays the fixed action in trompil 2, fixing device 4 includes a plurality of square steels of the adjacent range of surface that support 1 along the centre form, the 4 outsides of fixing device are equipped with the ribbon that plays the fixed action.
The length direction of the square steel is the same as that of the beam plate.
The outer surface of the fixing device 4 is provided with a plastic film layer 5.
Centre form support system adopts trompil hole or many trompils, adjustable centre form space size to adapt to assembling of different beam slab centre forms, the centre form mainly is assembled by square steel and is constituteed, at first relates to processing centre form support system according to the beam slab, assembles the centre form at the inner chamber bottom plate earlier, and every 2 meters installation template support system is a set of, then assembles web and roof shaped steel along support system, and every 2 meters ligature steel ribbons are one, parcel plastic film, can accomplish to this assembling around the shaped steel centre form system.
