Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction devices, in particular to a special-shaped component formwork support device. BACKGROUND

[0002] The building formwork is a temporary support structure, which is made according to the design requirements, so that the concrete structure and component are shaped according to the specified position and geometric size, and the correct position is maintained, and the self-weight of the building formwork and the external load acting on it are also borne. The formwork support system usually has a vertical support system, a horizontal support system and an inclined support system. However, the formwork used for special-shaped components is not on a horizontal plane, so when supporting the formwork for special-shaped components, a special-shaped component formwork support device is often needed to support it, such as the formwork support frame disclosed in Chinese Patent No. CN218715076U, which comprises a support member, a lifting assembly and a mounting assembly. The lifting assembly is installed at the top of the sleeve, and the mounting assembly is installed at the bottom of the sleeve. The lifting assembly comprises a lifting member and a limiting member. The lifting member comprises a hand wheel, a screw rod seat and a lifting screw rod. The screw rod seat is welded to the top of one side of the sleeve. When using the device to support the formwork, the lifting structure can be directly adjusted during the supporting process. The length of the support rod is adjusted to match the lifting member for fine adjustment. The formwork is quickly positioned. When the formwork needs to be accurately positioned, the lifting assembly can be directly adjusted to improve the installation efficiency of the formwork. In the special-shaped component and variable cross-section, the support member and the lifting assembly can be adjusted to match the variable cross-section to ensure that the formwork support is evenly and stably stressed. Especially when the formwork joint position uses the support member, the formwork joint position can be adjusted by the lifting member.

[0003] The formwork support device in the prior art described above can form a support surface matching the surface of the special-shaped component formwork by adjusting the height of at least two support plates when supporting the formwork, and can then support the special-shaped component. However, during the construction process, the surface hardness of the formwork support surface of the special-shaped component cannot be detected. When the formwork ages, the surface hardness of the support surface is low, which can cause extrusion to the surface of the formwork when supporting the surface of the formwork, and can damage the support surface of the formwork, so that the formwork cannot be effectively supported.

[0004] Therefore, we propose a special-shaped component formwork support device. SUMMARY

[0039] Compared with the prior art, the present application has the beneficial effects that:

[0040] Preferably, the present application has the beneficial effects that:The present invention arranges a sliding seat to move in a direction away from the support seat, so that the roller can roll on the surface of the special-shaped component template. During the rolling process, the pricking mechanism is triggered to poke the surface of the special-shaped component template to detect the hardness of the special-shaped component template surface.
