Description

A kind of prestressed stretch-draw Working rack that is used for precast beam
Technical field
The utility model belongs to science of bridge building Architectural Equipment technical field, relates to a kind of prestressed stretch-draw Working rack that is used for precast beam specifically.
Background technology
At present, in highway bridge post stressed concrete work progress, prestress wire stretch-draw is one critical process, and it directly influences the stretch-draw quality of precast beam.And in the stretching process of precast beam, the meeting accurate in place of jack directly influences the quality and the efficient of stretch-draw, and whether jack is in place accurate, and key is the prestressed stretch-draw support.Prestressed stretch-draw support commonly used at present has three kinds: first kind is to adopt steel pipe to be welded temporarily; Second kind is that an end places the cantilever support on the back; The third is to adopt portal support to build temporarily.Though these prestressed stretch-draw supports can satisfy the stretch-draw demand under certain condition, all there is operation inconvenience, locatees shortcomings such as inaccurate, and be not easy to dismantle, shift and carrying.
Because there is multiple inconvenience in prestressed stretch-draw support of the prior art; Therefore people are attempting the stretch-draw support is improved; Like the patent No. is that 201020158721.2 Chinese utility model patent just discloses a kind of box girder pre-stressed stretch-draw Working rack; Though this support improves prestressed stretch-draw support of the prior art to a certain extent, still there is following deficiency in this support: the one, and this support adopts an end to place the cantilevered fashion of back, needs could shift after the dismounting; The 2nd, this support needs support customized again for the beam slab of differing heights, causes waste of material; The 3rd, horizontal travelling car places and vertically moves on the cart, in practical operation, more difficulty is arranged, particularly for higher beam slab.
The utility model content
The utility model provides a kind of prestressed stretch-draw Working rack that is used for precast beam that shifts and can adapt to different deck-moldings simple in structure, easy to operate, convenient in order to overcome the deficiency that prior art exists.
The utility model is realized through following technical scheme: a kind of prestressed stretch-draw Working rack that is used for precast beam, and it mainly first is connected support, second and connects that support, the 3rd connects support, laterally locomotive support and the horizontal locomotive that is positioned on the said horizontal locomotive support are formed by what set gradually from bottom to top; Bottom at the first connection support is provided with four wheels; Top at horizontal locomotive support is provided with horizontal locomotive wheel rail, and laterally locomotive comprises mobile wheel, horizontal locomotive crossbeam, is positioned at the horizontal locomotive pedestal at horizontal locomotive crossbeam two ends and passes through the suspension hook of wire rope hanging under horizontal locomotive crossbeam.
The said first connection support, the second connection support, the 3rd connection support and horizontal locomotive support are by four standpipes and be arranged at cross-brace pipe and the oblique stay pipe composition between adjacent two standpipes; Be socketed with fixed muffle between two standpipes of next-door neighbour up and down, such structure can guarantee respectively to connect stablizing between the support.
The said first connection support is the first high connection support of 10cm.
The said second connection support is the second high connection support of 20cm.
Said the 3rd connection support is the 3rd a high connection support of 50cm.
Said horizontal locomotive support is the high horizontal locomotive support of 15cm.
Four wheels of the said first connection frame bottom are four universal wheels.
The horizontal locomotive crossbeam of said horizontal locomotive is welded by shaped steel.
Said wheel rail is welded by equilateral channel steel, is respectively arranged with block at the two ends of said wheel rail, is used for stoping horizontal locomotive to skid off.
The said prestressed stretch-draw Working rack that is used for precast beam connects support, the 3rd connection support and a horizontal locomotive support by several first connection supports, second and forms, thereby can adapt to the stretch-draw needs of different deck-moldings.
The beneficial effect of the utility model is: the prestressed stretch-draw Working rack that is used for precast beam of the utility model is compared with prestressed stretch-draw support of the prior art; The utility model is assembled by some connection supports of typing that need not height; So can adapt to the real work situation of different deck-moldings, be very easy to install; Owing to be provided with four universal wheels in the bottom of stretch-draw Working rack, so the prestressed stretch-draw Working rack of the utility model can shift easily and fast; The prestressed stretch-draw Working rack that is used for precast beam of the utility model is reasonable in design; Easy to operate, improved the quality and the efficient of the operation of precast beam prestressed stretch-draw greatly, laterally the locomotive crossbeam bears the load of jack; Jack is suspended on the suspension hook; Can guarantee the accurately in place of jack, thereby guarantee that jack is in place accurately, and then accelerating construction progress.
