Description

Technical Field

[0001] The utility model relates to the technical field of formwork engineering, in particular to a formwork support device. Background Art

[0002] During the construction of a concrete structure (such as a ship lock), the surface of the structure may be inclined. In this case, the formwork needs to be set obliquely. When the formwork is set obliquely, diagonal braces are usually set on the formwork to ensure the stability of the formwork and increase the safety of the formwork.

[0003] When setting the diagonal braces, usually one end of the diagonal brace is supported on the ground or the concrete structure surface, and the other end of the diagonal brace is supported in the middle of the formwork panel. This setting method has the following problems: during the construction of mass concrete (the minimum geometric size of the concrete structure entity is not less than 1m, or the concrete that is expected to cause harmful cracks due to temperature changes and shrinkage caused by the hydration of cement in the concrete), the concrete bin is large, and multiple diagonal braces need to be set for the inclined formwork of each bin. As the height of the concrete pouring increases, the diagonal braces are gradually buried in the concrete. Since the formwork is set obliquely and the diagonal braces are supported in the middle of the formwork panel, the diagonal braces cannot be pulled out during the concrete construction process. After the concrete pouring is completed, the diagonal braces are left in the concrete structure, resulting in waste of formwork support materials and increased construction costs; the diagonal braces are generally made of steel pipes. After the formwork is removed, it is necessary to grout the diagonal braces left in the concrete structure to fill the gaps of the diagonal braces. This method will further increase the material cost and labor cost, and at the same time reduce the construction efficiency of the concrete structure. Summary of the Utility Model

[0004] One of the purposes of the utility model is at least to provide a formwork support device for overcoming the problems existing in the above-mentioned prior art, which can pull out the formwork support device during the concrete pouring process, increase the reuse efficiency of the formwork support device, and can also avoid subsequent grouting of the concrete structure, thereby reducing the construction cost of the concrete structure.

[0005] In order to achieve the above purpose, the technical solutions adopted by the utility model include the following aspects.
