Description
Technical field
The utility model relates to the prefabricated instrument of bridge construction concrete core slab, and the particularly prefabricated internal mold of a kind of concrete core slab and assembling frame improve the prefabricated efficiency of concrete core slab.
Background technology
Along with the application of concrete core slab prefabricating technique with improve constantly, the prefabricated progress of cored slab is also more and more faster, and cored slab internal mold packaging technology is also tending towards variation, but application at present comparatively general or steel plate internal mold.Steel plate internal mold is that merogenesis is assembled, and every joint is provided with left and right two parts bolt, between joint and joint, is joined with bolts, and forms an integral inside molding consistent with concrete core slab inside dimension, length is consistent, by straddle truck or crane lifting.When cored slab carries out internal mold dismounting after building, first by workman, in the inside of steel plate internal mold, set bolt is removed, internal mold merogenesis burst could be removed.Although in this kind of steel plate, mold technique is very ripe, but has many drawbacks: 1, steel plate internal mold dead weight is larger, in assembling and demolishing process, the artificial and machinery needing is more, in operation, workman is existed to potential safety hazard.2, because steel plate internal mold, from great, so in integral hoisting process, easily push web reinforcement skeleton and make its distortion, destroy cushion block of concrete bar protective layer while transferring template, causes built cored slab finished product protection layer became uneven.3, when a slice steel form distortion is larger, cannot repair smoothly, must change separately, so just increased production cost.4, steel plate internal mold is removed from assembling---integral hoisting---, and whole process spended time is longer, affects project progress, increases project cost.5, cored slab inner chamber is generally at 30cm-90cm, and workman cannot normally work in inside.So building of concrete core slab needs a kind of light and fast, maneuverable prefabricated internal mold to solve the problems referred to above.
Summary of the invention
The purpose of this utility model is to provide the prefabricated internal mold of a kind of concrete core slab and assembling frame, be intended to solve the defect in existing steel plate inner mould technology, make its prefabricated internal mold light, assembly and disassembly are convenient, accelerate the progress of the interior mold forming of cored slab and installation, thereby improve the efficiency of building of concrete core slab prefabricated component.
The utility model is achieved in that
The prefabricated internal mold of concrete core slab comprises steel pipe, bracing frame and an outsourcing cloth, steel pipe is placed in to the periphery of bracing frame, and the corner of bracing frame and steel pipe are tied up fixing, and outsourcing cloth is wrapped in the outside of steel pipe and ties up fixing.
Assembling frame for the prefabricated internal mold of a kind of concrete core slab comprises vertical rod, base plate and positioning bar, and vertical rod is welded on the both sides of base plate, between vertical rod and base plate, welds positioning bar.Positioning bar conforms to the polycrystalline substance of bracing frame with the polycrystalline substance that base plate forms, and the width between two vertical rods conforms to the width of concrete core slab inner chamber.
The utility model remarkable result is compared with prior art: use steel pipe and bracing frame to manufacture cored slab internal mold and have and manufacture simple, easy to operately, the internal mold manufactured is light, save the advantages such as cost.According to the length of cored slab, the prefabricated internal mold of concrete core slab is can merogenesis assembled, due to each joint be all one independently whole and there is certain thickness, between joint and joint, need overlap with outsourcing cloth.According to the cross sectional shape of cored slab, by adjusting bracing frame and the assembling size and dimension of frame and the quantity of steel pipe used, can make the cored slab internal mold of various sizes and various cross sectional shapes, for building the cored slab of various sizes and shape.The utility model is used steel pipe assembled not only easy to operate, and is easy to change and maintenance, and selection is convenient, manufactures cost low.The dismounting of the utility model assembling simple and fast, particularly internal mold is more convenient, operates among piercing internal mold without personnel, only need to remove the tied silk of tying up of steel tube end part bracing frame, just steel pipe can be extracted out, bracing frame is pushed over and taken out of, operation is very easy.Save labour, accelerated project progress, guaranteed safety in production.Significantly improve the prefabricated efficiency of cored slab, reduced production cost, there is good use value.
Accompanying drawing explanation
Fig. 1 is building block principle schematic diagram of the present utility model.
Fig. 2 is the prefabricated internal mold sectional view after the utility model assembling.
The specific embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, and unrestricted protection domain of the present utility model.Referring to Fig. 1 and Fig. 2, the prefabricated internal mold of a kind of concrete core slab comprises steel pipe 3, bracing frame 2 and outsourcing cloth 5, steel pipe 3 is placed in to the periphery of bracing frame 2, and the corner of bracing frame 2 and steel pipe 3 are tied up fixing, and outsourcing cloth 5 is wrapped in the outside of steel pipe 3 and ties up fixing.Bracing frame 2 is frame shape structures, welding reinforcement 4 in frame, and the profile of bracing frame 2 conforms to the cavity shape of concrete core slab; One side angle corner and the steel pipe 3 of bracing frame 2 are tied up fixing.According to the shape of bracing frame 2, reinforcement 4 can be ╋ type, Х type, Η type, ¤ type or intersecting parallels structure.Steel pipe 3 is square steel tube or many shuttles shape steel tube, ease of assembly; Outsourcing cloth 5 is Polypropylence Sheet or the rubber cloth of thickness more than 0.2mm, can be fixed steel pipe 3 on the one hand, can also mortar leakage prevention.
Assembling frame for the prefabricated internal mold of a kind of concrete core slab comprises vertical rod 1, base plate 6 and positioning bar 7, and vertical rod 1 is welded on the both sides of base plate 6, between vertical rod 1 and base plate 6, welds positioning bar 7.Positioning bar 7 conforms to the polycrystalline substance of bracing frame 2 with the polycrystalline substance that base plate 6 forms, and the width between two vertical rods 1 conforms to the width of concrete core slab inner chamber.
Use the assemble method of assembling frame to be:
