Description

A mobile formwork for intermediate partition walls that can remove concrete bubbles

Technical field

The utility model relates to the technical field of movable formwork, specifically a movable formwork for a middle partition wall that can remove concrete bubbles.

Background technique

The middle partition wall is a main stress-bearing structure of the double-arch tunnel. The construction of the middle partition wall usually involves the assembly of small steel modules for large-section construction, and the use of brackets and tie rods as the formwork support system. For example, the public number is "CN212670637U "A vertical sliding formwork for wall construction that can be slid laterally. It has a reasonable structure, is quick to assemble on site, and has strong practicability. It can meet the stability during pouring and realize the overall erection of a large-span formwork support system. The formwork, formwork removal and moving operations improve the construction efficiency. At the same time, there is no need for repeated disassembly and adjustment in the future, which greatly reduces personnel investment and effectively reduces the amount of high-altitude work. However, the vertical sliding formwork for wall construction is actually used in practice. The following shortcomings still exist in the process:

The traditional mobile formwork is in contact with the ground through screw diagonal braces, which can ensure stability during pouring. However, the screw diagonal braces require workers to manually rotate and contact the ground, making the operation more troublesome and inconvenient to use. When pouring concrete, air is easily mixed in, causing air bubbles to form between the concrete. If not handled in time, the interior of the concrete will not be dense, thereby reducing the strength of the concrete.

Therefore, we proposed a mobile formwork for the intermediate partition wall that can remove concrete bubbles, which can solve the above problems well.
