A detachable cover beam bottom form support and its construction technology

Abstract

The present invention relates to a detachable cover beam bottom mold support and its construction technology. The detachable cover beam bottom form support includes two first fixed supports, several second fixed supports, several detachable supports and a lifting structure. The first fixed bracket, the second fixed bracket and the detachable bracket are all right-angled triangle structures, and one side of the right angle is parallel to the horizontal plane. In the present invention, the detachable cover beam bottom mold support and its construction technology have achieved ideal results in practical applications. The detachable support is supported by liftable structures (such as jacks, sandboxes, etc.), and the installation process is convenient; After the concrete pouring is completed, the detachable support is removed by lowering the height of the lifting structure to ensure sufficient anchorage prestressed tension space. At the same time, it is easy to disassemble and reduce unnecessary damage to the concrete structure. The construction is safe and reliable. All supports in this construction process All can be recycled, easy to disassemble, reduce investment in mechanical equipment and personnel, and reduce engineering costs.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a detachable cover beam bottom form support and a construction process thereof. Background technique [0002] The bottom of the cast-in-place prestressed reinforced concrete cover beam is supported by brackets, and the overhanging arm is supported by a triangular bracket. The prestressed tension anchor of the cover beam is located under the cantilever. During construction, the first batch of prestressed tension should be carried out before the concrete of the cover beam reaches a certain strength and the bottom form is removed. Therefore, the triangular bracket at the cantilever and the prestressed tensioned Conflict and need to be removed. In the existing construction technology, the triangular bracket at the cantilever at the bottom of the cover beam is a fixed structure, and after the concrete pouring of the cover beam is completed, the concrete will press the tr...

AI Technical Summary

Problems solved by technology

The prestressed tension anchor of the cover beam is located under the cantilever. During construction, the first batch of prestressed tension needs to be carried out before the concrete of the cover beam reaches a certain strength and the bottom form is removed. Therefore, the triangular bracket at the cantilever and the prestressed tension Conflict and need to be removed. In the existing construction technology, the triangular bracket at the cantilever at the bottom of the cover beam is a fixed structure, and after the concrete pouring of the cover beam is completed, the concrete will press the triangular bracket, making it difficult to remove the bracket. In the prior art, the bracket is removed The best method is to directly drag the bracket out. Due to the influence of concrete gravity, it will inevitably cause damage to the concrete structure of the cap beam or the bracket, seriously affecting the construction quality and construction progress, and needs to be improved.
