Description

Whole extracting tool of bent cap support

Technical Field

The utility model relates to the technical field of support disassembling tools, in particular to a cover beam support integral disassembling tool.

Background

The construction of the bridge capping beam is a relatively complex construction procedure, and the method of using the hoop bracket in the construction of the capping beam is common, and the hoop bracket consists of a steel hoop, a bailey sheet or other steel longitudinal beams and a transverse small distribution beam. And when the concrete pouring is finished and the strength meets the design and standard requirements, the support and the concrete bottom die need to be removed. The traditional support dismantling method comprises the following steps: when the anchor ear support is installed, a jack or a sand cylinder is installed between the anchor ear and the longitudinal beam, the height of the support is reduced through the jack or the sand cylinder, the bottom die is firstly detached through the cooperation of a crane, and then the transverse small distribution beam, the longitudinal beam and the anchor ear are separated from each other in a layering mode from top to bottom through the crane. The traditional dismounting method has the problems of high cost, complex manufacturing and installation of the sand cylinder, difficulty in adjusting the height of the support by the sand cylinder before the bent cap construction, poor stability when the sand cylinder and a jack fall down, high overall collapse risk of the support, slow dismounting speed, high time cost and the like due to the fact that the bent cap hoop support can be dismounted only by matching of a crane.

The existing method for disassembling the bent cap hoop support comprises the following steps: two I-steel supports perpendicular to the cover beam are mounted on the cover beam, two ends of each I-steel support are respectively provided with a chain block, and the four chain blocks hook the longitudinal beams supported by the hoop support. The advantages are that: simple operation, construction are swift, the security is high, economical and practical, have overturned traditional dismantlement staple bolt support order, but, the length of I-steel is fixed, and the suitability is not strong, and the practicality is not strong.

Therefore, it is a problem worth studying to provide a tool for disassembling the whole bent cap support, which has an adjustable length of the supporting component, can be adapted to bent caps with different sizes and has strong practicability.

Disclosure of Invention

The utility model aims to provide the bent cap supporting device which is simple in structure, convenient to use, adjustable in length of the supporting assembly, adaptable to bent caps with different sizes and high in practicability.

The purpose of the utility model is realized as follows:

the utility model provides a whole extracting tool of bent cap support, is including setting up the supporting mechanism on the bent cap, the supporting mechanism includes two at least supporting component, the supporting component sets up in the telescopic link at backup pad both ends, sets up in the link of the telescopic link other end including setting up backup pad, the activity on the bent cap, sets up the rolling subassembly on the link, and the longeron that supports on the staple bolt is caught on to the lower extreme of rolling subassembly.

The supporting plate is provided with a screw hole in a penetrating mode, and the telescopic rod is a screw rod arranged in the screw hole in a threaded mode.

The hanging ring is fixedly connected with the end part of the screw rod.

The winding assembly adopts a chain block.

The tonnage model of the chain block is selected according to the dead weight of the bracket.

Has the positive and beneficial effects that: the supporting assembly comprises a supporting plate arranged on the cover beam, telescopic rods movably arranged at two ends of the supporting plate and hanging rings arranged at the other ends of the telescopic rods, the length of each telescopic rod is adjustable, the length of the supporting assembly can be adjusted according to the width of the cover beam to enable the supporting assembly and the cover beam to be matched, and the practicability is high.

FIG. 2 is a right side view of FIG. 1;

FIG. 3 is a schematic structural view of the support assembly of the present invention;

FIG. 4 is a top view of FIG. 3;

in the figure, the following steps are carried out: the device comprises a hoop 1, longitudinal beams 2, transverse distribution beams 3, an operating platform 4, a supporting mechanism 5, a supporting plate 501, a screw 502, a hanging ring 503, a screw hole 504 and a chain block 6.

Detailed Description

The utility model is further illustrated by the following figures and examples.

Example 1

As shown in fig. 1-4, the tool for integrally disassembling the bent cap support comprises a supporting mechanism installed on the bent cap, wherein the supporting mechanism comprises two supporting components 5, the two supporting components 5 are respectively installed at the left end and the right end of the bent cap, and the two supporting components 5 are arranged along the width direction of the bent cap. The supporting component 5 comprises a supporting plate 501 arranged and installed on the cover beam along the width direction of the cover beam, a telescopic rod movably installed at the front end and the rear end of the supporting plate 501, and a hanging ring 503 installed at the other end of the telescopic rod. Wherein, the supporting plate 501 is provided with a screw hole 504 along the length direction (i.e. the width direction of the cover beam), and the telescopic rod is a screw rod 502 which is installed in the screw hole 504 in a threaded manner. The total length of the support plate 501 and the two screws 502 mounted on the support plate can be changed by rotating the screws 502, so that the operation is simple and the adjustment is convenient. The length of the supporting component 5 can be adjusted according to the width of the cover beam, so that the two are adaptive, and the practicability is high.

The hanging ring 503 is welded with the end of the screw 502, and the preparation process is simple, and the connection is firm and reliable. The chain block 6 is hung on the hanging ring 503.

The support comprises a longitudinal beam 2 supported at the top of a hoop 1 and an operating platform 4 supported on the longitudinal beam 2 through a plurality of transverse distribution beams 3 which are uniformly arranged.

The chain block 6 is in the prior art, the tonnage model of the chain block is selected according to the dead weight of the bracket, and further description is omitted here. The lower end of the chain block 6 hooks the longitudinal beam 2 supported on the hoop 1.

The method comprises the following operation steps:

1. the supporting mechanism is arranged on the cover beam and comprises two pairs of supporting components 5, the total length of the supporting plate 501 and the two screws 502 arranged on the supporting plate can be changed by rotating the screws 502 according to the width of the cover beam, the operation is simple, the adjustment is convenient and fast, and therefore the purpose of adjusting the length of the supporting components 5 is achieved, the supporting components are matched with the cover beam, and the practicability is high;

2. a chain block 6 is hung on each of the four hanging rings 503, and the lower end of the chain block 6 hooks the longitudinal beam 2 supported on the hoop 1;

3. meanwhile, the stress condition of the four chain blocks 6 is slowly adjusted, when the weight borne by the hoop 1 is completely transferred to the supporting mechanism on the cover beam, the whole hoop 1 is kept stable, and the hoop 1 is disassembled;

4. after the hoop 1 is disassembled, the chains of the four chain blocks 6 are simultaneously lowered at the same speed, and the longitudinal beam 2, the transverse distribution beam 3 positioned on the longitudinal beam 2 and the operating platform 4 integrally fall until the chains are stably placed on the ground.
