Description

Technical Field

[0001] The invention belongs to the technical field of post-casting strip formwork support, and in particular relates to an adjustable post-casting strip independent support device and a realization method thereof. Background Art

[0002] The post-cast strip is a cast-in-place integrated reinforced concrete structure. During the construction process, in order to effectively solve the cracking and deformation joints caused by temperature, shrinkage and other reasons, it is closed after a long time, thus connecting the structure into a whole.

[0003] The post-cast strip of the basement is generally a settlement post-cast strip. Since the closure date is relatively late, the support form of the post-cast strip needs to adopt an independent support system, but there are some problems in the actual operation process, such as:

[0004] (1) It is difficult to separate the support structure from the surrounding formwork and keels during actual construction on site. Therefore, independent support is basically not carried out during on-site construction. Therefore, when the concrete strength reaches the conditions for demolding, all the keels and other materials are removed first, and then the formwork frame is re-supported at this location. This will create a false phenomenon that the frame is independently supported at the post-casting strip. When the post-casting strip is not closed and the structures on both sides are in a cantilevered state, as long as the supporting structure is removed and then the frame is re-supported, the components will sink downward, resulting in destructive cracks and even safety and quality accidents, making it impossible to play the role of the independent formwork system.

[0005] (2) Before closing the post-casting strip, the concrete surfaces on both sides of the post-casting strip must be chiseled and the debris inside the post-casting strip must be cleaned up. However, due to the independent support top of the traditional construction method, there are dense keels, which makes it difficult for construction workers to directly chisel the concrete surfaces on both sides of the post-casting strip and remove the debris inside the post-casting strip. Therefore, on-site construction workers will first privately dismantle the frame, chisel and clean, and then restore the top to the original support form, which will still cause the components on both sides of the post-casting strip to sink downward and even crack.

[0006] (3) The traditional post-casting support frame is set up continuously, which is not conducive to the transportation of the basement. It will cause a certain impact, reduce the construction efficiency, and thus affect the interweaving of other processes. Summary of the invention

[0014] In order to increase the supporting area and ensure the supporting effect, further, the upper end of the fine-tuning rod is connected with a top plate.
