Abstract

The utility model relates to an internal steel mold for hollow slab girder construction, and mainly aims to solve the problems of small dead weight, small rigidity and the like of a conventional internal mold. The internal steel mold for the hollow slab girder construction comprises an upper half internal steel mold and a lower half internal steel mold which adopt the same structure, wherein both the upper half internal steel mold and the lower half internal steel mold comprise two steel plates provided with approximate L-shaped cross sections, and steel angles are fixed at the horizontal edge ends of the steel plates and connected together through movable pins; both the upper half internal steel mold and the lower half internal steel mold comprise a steel channel and two rows of hinge plates, one end of each hinge plate is fixed on each steel channel through a bolt, the other ends of the hinge plates are fixed on the vertical edges of the steel plates on two sides of each steel channel respectively through bolts, and traction holes are formed in the end parts of the steel channels; and chamfer angles with inward bevel edges are arranged at the upper ends of the vertical edges of the two steel plates of the upper half internal steel mold, and chamfer angles with outward bevel edges are arranged at the upper ends of the vertical edges of the two steel plates of the lower half internal steel mold. The internal steel mold for the hollow slab girder construction has the advantages of large rigidity and convenience in mounting and dismounting.

Description

A kind of constructing hollow slab beam steel internal mold
Technical field:
The steel internal mold using when the utility model relates to a kind of constructing hollow slab beam.
Background technology:
At present, during constructing hollow slab beam, external mold adopts outer steel mould substantially, and internal mold generally common are two kinds the most, and a kind of is rubber pneumatic bag core, and another kind is the assembled core of wooden model.The weak point of above two kinds of internal molds is, air bag core is in practice of construction, and because hollow slab beam inside casing is larger, the deadweight of air bag core is little, especially easy floating in concrete casting process.The assembled core of wooden model need be made according to plate-girder inside casing concrete shape, is difficult for processing, and whole rigidity do not reach requirement, and template piecemeal is more in addition, scattered especially, assembled and dismounting all inconvenient, length expends time in.Wooden model easily damages in unloading process, and wooden model deadweight is lighter, in building concrete process, also easily floats.
Summary of the invention:
It is large that technical problem to be solved in the utility model is to provide a kind of integral rigidity, easy accessibility, and during dismounting, template can be out of shape, and can improve the constructing hollow slab beam steel internal mold of construction quality and construction speed.
Above-mentioned purpose is achieved in that it is comprised of upper half steel internal mold and lower half steel internal mold, wherein go up half steel internal mold identical with the structure of lower half steel internal mold, all comprise that two cross sections are for approximate L shaped steel plate, the horizontal sides end of two block plates is all fixed with angle steel, angle steel in two block plate horizontal sides links together by removable pin, also comprise a channel-section steel, channel-section steel be positioned at the angle steel that links together by removable pin directly over, also have two row's loose-leaf boards, one end of this two rows loose-leaf board is all bolted on channel-section steel, wherein the other end of row's loose-leaf board is bolted on the vertical edge of a block plate, the other end of another row's loose-leaf board is bolted on the vertical edge of another block plate, towing pad is established in the end of channel-section steel,
The vertical edge upper end of upper half steel internal mold two block plate is all provided with chamfering, and the hypotenuse of these two chamferings is towards the inside; The vertical edge upper end of lower half steel internal mold two block plate is also all provided with chamfering, and the hypotenuse of these two chamferings is towards outside.
Installing/dismounting method: during installation, by the vertical edge of upper half steel internal mold down, by the vertical edge of lower half steel internal mold upward, first with straddle truck, lower half block steel internal mold is installed, and then upper half block steel internal mold is tipped upside down on lower half block steel internal mold, make the chamfering close contact on upper and lower half steel internal mold, then each removable pin and bolt are reinforced.During dismounting, first each removable pin and bolt are unscrewed, then by wire rope Peng on the towing pad of upper half block steel internal mold, each loose-leaf board on upper half block steel internal mold packs up and drives the steel plate of both sides to draw in, make it separated with the concrete after initial set, continue traction, upper half steel internal mold is shifted out, and then by same procedure, lower half steel internal mold is shifted out.
The utility model has the advantages that: integral rigidity is large, easy installation and removal, quick, during installing/dismounting, template can be out of shape, and can improve construction quality and construction speed.
Accompanying drawing explanation:
Fig. 1 is side-looking cross-sectional view of the present utility model;
Fig. 2 is the plan structure schematic diagram of lower half steel internal mold in the utility model.
The specific embodiment:
With reference to Fig. 1, 2, it is comprised of upper half steel internal mold and lower half steel internal mold, wherein go up half steel internal mold identical with the structure of lower half steel internal mold, all comprise that two cross sections are for approximate L shaped steel plate 1, the horizontal sides end of two block plates is all fixed with angle steel 2, angle steel in two block plate horizontal sides links together by removable pin 3, also comprise a channel-section steel 4, channel-section steel be positioned at the angle steel that links together by removable pin directly over, also have two row's loose-leaf boards 5, one end of this two rows loose-leaf board is all bolted on channel-section steel 4, wherein the other end of row's loose-leaf board is bolted on the vertical edge of a block plate, the other end of another row's loose-leaf board is bolted on the vertical edge of another block plate, towing pad 6 is established in the end of channel-section steel,
The vertical edge top of upper half steel internal mold two block plate is all provided with chamfering 7, and the hypotenuse of these two chamferings is towards the inside; The vertical edge top of lower half steel internal mold two block plate is also all provided with chamfering, and the hypotenuse of these two chamferings is towards outside.
