Description

Technical Field

[0001] The utility model relates to the field of pier pouring, in particular to a splicing formwork for pier pouring. Background Technique

[0002] A pier is a structure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. The abutments are located at both ends of the bridge, and the piers are located between the two abutments. The function of the pier is to support the bridge span structure. In addition to supporting the bridge span structure, the abutment also needs to connect with the embankment and prevent the embankment from sliding. To protect the abutment and the embankment filling, some protection and diversion works are often done on both sides of the abutment. The intermediate support structure of a multi-span bridge is called a pier, and generally, piers are cast in place, so formwork is required.

[0003] According to the Chinese patent with the publication number CN211646005U, a pier pouring mold for bridge support is disclosed. In this pier pouring mold for bridge support, by using the mounting blocks fixedly connected to the four sides of the formwork, the formwork can be divided into small pieces of appropriate size, effectively reducing the problem of the excessively high self-weight of the integral formwork. Moreover, the design of the mounting handle enables the formwork to be lifted by a crane during installation, facilitating positioning and disassembly. Additionally, the block-shaped splicing design improves the applicability of the pouring mold.

[0004] Regarding the above-mentioned disclosed patent content, there are fixing plates, handles and fixing grooves. After the formwork is spliced, to improve the stability of the formwork, the fixing plates are inserted into the fixing grooves, and the handles are used for limiting. The handles can only prevent the fixing plates from falling out from the front, but the fixing plates may move left and right and fall out from the side, thus making it difficult for the fixing plates to play a stabilizing role for the formwork, thereby reducing the limiting and fixing efficiency of the fixing plates. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a splicing formwork for pier pouring to solve the technical problem that the fixing plate may move left and right, thereby affecting its stabilizing effect.
