Description

Technical Field

[0001] The utility model relates to the technical field of a drop frame device, in particular to a drop frame device which can be quickly disassembled and assembled. Background Art

[0002] In the traditional cast-in-place box girder construction, steel pipe steel composite brackets or steel pipe Bailey beam brackets are mostly used as the box girder formwork support system. When the cast-in-place box girder is constructed, the support system needs to be dismantled. Due to the deadweight of the cast-in-place box girder, it is quite difficult to directly dismantle the bracket. Therefore, it is necessary to set a dismounting device between the steel pipe column and the load-bearing beam in advance when the bracket is erected. In the existing technology, there are two common methods for dismounting cast-in-place box girder brackets: direct cutting method and simple sand box. The direct cutting method wastes materials and is difficult to achieve synchronization of bracket dismounting. Its high-altitude operation is more dangerous. With the simple sand box, the sand discharge holes are controlled by bolts, and the bolts are screwed out to unload the sand. The sand discharge holes are small. Once the sand box is flooded, the sticky sand in the small sand discharge holes is difficult to discharge smoothly. Sometimes the bolts are rusted and sand cannot be discharged.

[0003] After searching, the patent publication number CN206267036U is a cast-in-place box girder support dismounting device, which includes an upper seat plate, a lower seat plate, a left support plate and a right support plate; the lower seat plate forms a left-right symmetrical slope surface on the upper surface of both sides, and the upper seat plate and the lower seat plate are symmetrical structures; the left support plate and the right support plate are wedge-shaped support blocks, which are supported between the upper seat plate and the lower seat plate, and the slope surface of the wedge-shaped support block is used to form a wedge-shaped match with the slope surface of the upper seat plate and the lower seat plate on both sides; a tie rod is set between the left support plate and the right support plate, and the tie rod passes through the center of the left support plate and the right support plate and is fastened at both ends with nuts to achieve support; after removing the nuts, the left support plate and the right support plate slide symmetrically to both sides to achieve dismounting. In the process of implementing this solution, it is found that the following problems in the prior art have not been well solved: the limiting mechanism when the upper seat plate is lowered is single, resulting in insufficient stability, thereby failing to ensure the implementation of safety and stability. Therefore, it is urgent to design a dismounting device that can be quickly disassembled and assembled to solve the above problems. Utility Model Content
