Abstract

The utility model relates to a cast-in-place roof beam die block and the whole device that unloads perpendicularly of bracket set up a preformed hole corresponding every hoisting point of die block and bracket on the cast-in-place roof beam of pouring completion, establish one respectively and fill up the roof beam in every preformed hole both sides on the bridge floor, weld a spandrel girder on two pad roof beams, a closed loop's wire rope is established to the cover on the spandrel girder, wire rope follows the preformed hole extends to the underbridge and connects a tackle group. The lead of the pulley group is connected with a hoisting point and is connected with a winch for traction, so that the whole vertical lowering of the bottom die and the bracket can be realized; the diameter of a preformed hole on the cast-in-place beam is small, and the cast-in-place beam has no influence on a stress structure of the bridge.

Description

Cast-in-place beam bottom die and bracket integral vertical unloading device

Technical Field

The utility model belongs to the technical field of the bridge construction, a side dismantlement construction such as die block and bracket after cast-in-place roof beam construction is accomplished is related to, concretely relates to cast-in-place roof beam die block and the whole device that unloads of bracket perpendicularly.

Background

After the construction of the cast-in-place beam is completed, when the structures such as the hanging basket bottom die and the construction bracket are disassembled, equipment such as a crane and a tower crane cannot be vertically lowered due to the blocking of the bridge floor, and if the equipment is hung below the bridge by a crane, the equipment belongs to askew pulling and inclined hanging forbidden in the construction specification, so that a decomposition and unloading mode is usually adopted in the construction, and the efficiency is low.

Disclosure of Invention

The utility model aims at the above problem, a whole device that unloads perpendicularly of cast-in-place roof beam die block is provided, improves the efficiency of construction.

The technical scheme of the utility model as follows:

the utility model provides a whole device that unloads perpendicularly of cast-in-place roof beam die block and bracket which characterized in that: a preformed hole is formed in each cast-in-place beam corresponding to each hanging point of the bottom die and the bracket, a pad beam is arranged on each of two sides of each preformed hole in the bridge floor respectively, a bearing beam is welded to the two pad beams, a closed-loop steel wire rope is sleeved on each bearing beam, and each steel wire rope extends to the position below the bridge from the preformed hole and is connected with a pulley set.

The trolley group is arranged under the bridge floor, the through hole reserved on the cast-in-place beam only needs to be penetrated by a steel wire rope, the aperture is small, and the steel wire rope has no influence on the stress structure of the bridge; the whole vertical downward placing of the bottom die and the bracket can be realized, and the construction efficiency can be improved on the premise of ensuring safety.

Drawings

Fig. 1 is a schematic elevation structure of the present invention;

fig. 2 is a schematic side view of the present invention.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses every hoisting point that corresponds die block and bracket on cast-in-place roof beam 1 that has built the completion sets up a preformed hole 2, and every preformed hole both sides establish respectively one on the bridge floor and fill up roof beam 3, weld a spandrel girder 4 on two pads roof beams, a closed loop's wire rope 5 is established to the cover on spandrel girder 4, wire rope 5 follows preformed hole 2 extends to under the bridge and connects a tackle 6.

When cast-in-place roof beam die block and bracket are dismantled, with the hoisting point on die block and the bracket of every pulley group wire one end connection, the hoist engine is connected to the other end, can realize through the drawing of hoist engine that die block and bracket are whole to transfer perpendicularly, and steerable speed of transferring, guarantee construction safety.

Claims

1. The utility model provides a whole device that unloads perpendicularly of cast-in-place roof beam die block and bracket which characterized in that: a preformed hole is formed in each hanging point, corresponding to the bottom die and the bracket, of the cast-in-place beam, a pad beam is arranged on each of two sides of each preformed hole in the bridge floor respectively, a bearing beam is welded to the two pad beams, a closed-loop steel wire rope is sleeved on the bearing beam, and the steel wire rope extends to the position below the bridge from the preformed holes and is connected with a pulley block set.
