Description

Technical Field

[0001] The utility model relates to the technical field related to building construction, in particular to a progressive fixing device for a template. Background Art

[0002] Formwork is the abbreviation of building formwork, and building formwork is a temporary supporting structure, which is made according to design requirements, so that concrete structures and components are formed according to specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the building formwork and external loads acting on it. The existing building formwork structure used for the construction of poured concrete structure projects is mainly composed of three parts: a panel, a support structure and a connector. However, the traditional fixing device for the formwork usually directly uses iron nails to nail the connecting wooden boards to adjacent formworks, and then uses a support rod-like structure to support and fix from the outer surface of the formwork. This fixing method will not only cause the formwork to be repeatedly nailed in and out during the installation and disassembly process, which will cause great damage to the formwork body, thereby resulting in a low actual service life of the formwork, and the iron nails fixed in the process of disassembling the formwork will also cause the disassembly process of the formwork to be delayed for a lot of time, and it will also leave certain safety hazards for operators during the ordering process. For this reason, the utility model proposes a progressive fixing device for the formwork to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a progressive fixing device for a template to solve the problems raised in the above background technology.

[0023] Furthermore, the slot edge of the installation slot 3 is a beveled edge, and the inclination angle of the edge matches the edge inclination of the connector 2, and the depth of the slot matches the thickness of the plate body of the connector 2. The edge of the reserved installation slot 3 is set as a beveled edge inclined outward, so that the connector 2 can be more convenient to install and remove;

[0025] Furthermore, the template 1 is a plastic template, and the copper nut 4 is fixedly embedded in the template when it is cast. By pre-embedding the copper nut 4 on the template 1, the plate body is installed using a screw structure. Compared with the traditional method of fixing the template 1 with iron nails, the degree of damage to the template body is smaller, thereby effectively extending the service life of the template 1;

[0026] Further, the connecting member 2 is fixedly welded on the connecting rod 6, and the connecting rod 6 is a long rod structure with a rectangular cross-section.
