Abstract
The utility model provides a draw-type movable internal mold for hollow plate girders, relating to a hollow plate girder internal mold. The utility model aims to solve the problems that the prior hollow plate girder internal mold is difficult to disassemble and assemble, difficult to have formworks fixed and positioned and easy to leak slurry, and cannot be reused, thereby causing the disadvantages of poor construction conditions and high construction cost. The left side and the right side of the end faces of an upper internal mold (1) and a lower internal mold (2) are respectively provided with a draw-pull reinforcement seat (4); movable formworks (3) are arranged between the upper internal mold (1) and the lower internal mold (2), and are fixed on the draw-pull reinforcement seats (4) through draw-pull reinforcing bars (5); and a cavity (6) is formed among the movable formworks (3), the upper internal mold (1) and the lower internal mold (2). According to the shape and size of a hollow plate girder part, the internal mold is divided into an upper part, a middle part and a lower part for design, so as to form an assembled-type steel-wood internal mold. The internal mold has the advantages of convenience for disassembly and assembly, accurate positioning, difficulty for slurry leakage and reusing capability, thereby reducing construction cost and improving construction conditions.
Description
Technical field
The utility model relates to a kind of hollow slab beam internal mold, belongs to the building structure technology field.
Background technology
Concrete hollow slab girder has from heavy and light, saves material, supporting capacity advantages of higher, but in its hollow slab beam internal mold construction, the internal mold that uses has segmentation and slicing dismounting internal mold and disposable internal mold at present, these internal mold ubiquity template dismounting difficulties, template is fixed and location difficulty, easily spillage, not re-usable problem, thereby has caused execution conditions difference and the high drawback of construction costs.Therefore, design a kind ofly is convenient to dismounting, accurate positioning, is difficult for spillage and reusable hollow slab beam internal mold becomes problem demanding prompt solution.
The utility model content
The purpose of this utility model is in order to solve that dismounting difficulty, template that existing hollow slab beam internal mold exists are fixed and location difficulty, easily spillage, not re-usable problem, cause the high drawback of execution conditions difference and construction costs, and then a kind of hollow slab beam odd test movable internal mold is provided.
The technical solution of the utility model is: hollow slab beam odd test movable internal mold comprises top internal mold, bottom internal mold, traveling formwork, withdrawing muscle seat and withdrawing reinforcing bar, the left and right sides of described top internal mold and bottom internal mold end face is separately installed with withdrawing muscle seat, described traveling formwork is arranged between top internal mold and the bottom internal mold, and be fixed on the withdrawing muscle seat by the withdrawing reinforcing bar, form cavity between in described traveling formwork and top internal mold and the bottom.
The utility model compared with prior art has following beneficial effect: the utility model designs internal mold branch upper, middle, and lower part according to the shape and the size of hollow slab beam part, forms an assembly type steel wood internal mold.The utlity model has be convenient to dismounting, accurate positioning, be difficult for spillage, reusable advantage, thereby reduced construction costs, improved execution conditions.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment is made up of top internal mold 1, bottom internal mold 2, traveling formwork 3, withdrawing muscle seat 4 and withdrawing reinforcing bar 5, the left and right sides of described top internal mold 1 and bottom internal mold 2 end faces is separately installed with withdrawing muscle seat 4, described traveling formwork 3 is arranged between top internal mold 1 and the bottom internal mold 2, and be fixed on the withdrawing muscle seat 4 by withdrawing reinforcing bar 5, form cavity 6 between described traveling formwork 3 and top internal mold 1 and the bottom internal mold 2.
The specific embodiment two: in conjunction with Fig. 1 present embodiment is described, the difference of the present embodiment and the specific embodiment one is that the utility model also increases polyethylene foam sheet 7, and described polyethylene foam sheet 7 is arranged between traveling formwork 3 and the withdrawing muscle seat 4.So be provided with, help the dismounting of traveling formwork 3.Other composition is identical with the specific embodiment one with annexation.
Operating principle
Dress is at first installed bottom internal mold 2 during mould, lays withdrawing reinforcing bar 5 on withdrawing muscle seat 4, polyethylene foam sheet 7 is set then and traveling formwork 3 is installed, and top internal mold 1 is installed, at last fixing internal mold; During form removal, pull out withdrawing reinforcing bar 5 earlier, make between traveling formwork 3 and top internal mold 1, bottom internal mold 2 and the sidewall concrete and form activity space, utilize after the final set of the lubrication of polyethylene foam sheet 7 and side concrete the very low characteristics of intensity in the certain hour then, traveling formwork 3 usefulness hoist engines in both sides are pulled out, to eliminate the bonding absorption of concrete to traveling formwork 3, treat that the beam slab concrete strength reaches after 50%, both sides traveling formwork 3 is all extracted out, top internal mold 1 is fallen on the bottom internal mold 2 simultaneously, and vibration can be taken out top internal mold 1 and bottom internal mold 2 gently.
Claims (2)
1, a kind of hollow slab beam odd test movable internal mold, it comprises top internal mold (1), bottom internal mold (2), traveling formwork (3), withdrawing muscle seat (4) and withdrawing reinforcing bar (5), the left and right sides that it is characterized in that described top internal mold (1) and bottom internal mold (2) end face is separately installed with withdrawing muscle seat (4), described traveling formwork (3) is arranged between top internal mold (1) and the bottom internal mold (2), and be fixed on the withdrawing muscle seat (4) by withdrawing reinforcing bar (5), form cavity (6) between described traveling formwork (3) and top internal mold (1) and the bottom internal mold (2).
2, according to the described hollow slab beam odd test of claim 1 movable internal mold, it is characterized in that it also comprises polyethylene foam sheet (7), described polyethylene foam sheet (7) is arranged between traveling formwork (3) and the withdrawing muscle seat (4).
