Description

Technical Field

[0001] The utility model relates to the field of template construction, in particular to a concrete template structure for rapid opening and closing construction. Background Art

[0002] Concrete formwork construction refers to the construction and fixing of the formwork before pouring concrete to construct the concrete. After ensuring that the concrete has completely hardened, the concrete formwork is dismantled and the formwork and supports are cleaned.

[0003] When using traditional steel formwork, the formwork is usually disassembled by prying with a crowbar to separate the formwork from the concrete, which is time-consuming and labor-intensive. Traditional steel formwork is inconvenient to disassemble, the disassembly efficiency is low, and it is easy to damage the concrete. The formwork is "stuck", and then the removed formwork causes damage to the concrete. At the same time, the existing formwork splicing is very difficult, and the splicing between the formworks is not stable enough, which can easily cause the formed plain concrete to deform or explode, and the disassembly process further exacerbates the "stuck" phenomenon of the formwork. For this reason, we propose a concrete formwork structure with rapid opening and closing construction to solve the above problems. Utility Model Content

[0004] The utility model provides a concrete formwork structure for rapid opening and closing construction, which solves the problems of inconvenient disassembly of steel formwork, low disassembly efficiency, easy damage to concrete, and "stuck" phenomenon of formwork, which then damages concrete when removed. At the same time, the existing formwork splicing is very difficult, and the splicing between formworks is not stable enough, which easily leads to deformation or bursting of the formed plain concrete.

The U-shaped slider enters the slide formed by the two L-shaped slides from one side of the L-shaped slide. The U-shaped plate is connected to the two U-shaped sliders. The U-shaped slider can slide relative to the U-shaped frame so that the disassembly structure can adapt to rectangular plates of different heights, so that different main formwork heights and disassembly structures can be installed on the U-shaped frame. When disassembling the main formwork, after removing the connecting rod, the main formwork is separated from the concrete, and the U-shaped frame is separated from the rectangular plate by turning the handle, and then the bolts between the U-shaped plate and the U-shaped slider are removed.

When disassembling, multiple main templates can be disassembled from top to bottom in sequence, which is convenient for the overall template disassembly. It avoids the "stuck" phenomenon of the main template, thereby avoiding the damage to the concrete caused by the removed template. At the same time, the disassembly is quick and the disassembly efficiency is improved, which has great promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
