Description

A bidirectional hydraulic self-servo support device for unilateral formwork

technical field

The utility model belongs to a tool for building formwork construction, in particular to a bidirectional hydraulic self-servo supporting device used for a unilateral formwork support body.

Background technique

During the construction of the basement exterior wall, the space between the supporting piles and the exterior wall to be constructed is small, and the supporting piles often appear out of position, resulting in further narrowing of the space for the fertilizer groove, which is reserved for the formwork support on the outside of the basement exterior wall. The operating space is extremely limited. In some projects using bored piles + reverse construction, the basement exterior wall is a vertical support structure, and the space between the support pile and the exterior wall is small, and the average distance is only 400~800mm. Due to the offset phenomenon, the minimum distance between the site support pile and the outer wall is only 150~200mm. The traditional double-sided formwork is used, which is difficult to construct.

Based on the above situation, unilateral formwork has become an ideal and effective construction technology for exterior wall construction. At present, the unilateral formwork frame body is mostly in the form of steel pipe fastener scaffolding and diagonal struts, and the construction of the outer wall can be carried out in stages. The construction period was slowed down, and labor costs and material losses were also increased. In addition, the use of this frame must reserve steel bars in the basement floor for fixing the bottom of the steel pipe, which further increases the process of erecting the frame. Therefore, the movable section steel throwing support is used for the basement exterior wall and other unilateral formwork construction processes. It can well solve the problem of frame turnover, without the need to reserve steel bars in advance, with good stability and easy movement. Quick-flow construction without dismantling and building.

The height and width of the outer wall can be different. The movable section steel prop must be customized according to the height and width of the outer wall, otherwise the safety and stability requirements of the frame body cannot be met. When the basement of a project has many different When the height of the outer wall is high, the movable section steel throwing support must be customized according to different heights to ensure that the stability of the frame body meets the requirements, and it cannot be universal.
