Description

Technical Field

[0001] The utility model relates to the technical field of invert formwork construction equipment, in particular to a slidable invert formwork for building construction. Background Art

[0002] When concrete construction is carried out in a tunnel, it is necessary to first pour the concrete of the arc invert layer, and then pour the concrete of the upper filling layer. Pouring the concrete of the arc invert layer is generally realized by using an arc invert formwork.

[0003] In the related art, after a section of construction pouring is completed, it is necessary to remove the formwork of the invert formwork. However, when removing the formwork of the invert formwork, it is necessary for workers to manually remove the formwork, which has a large labor intensity and low work efficiency. For this reason, a hydraulic and electric walking trestle has been introduced in the market. Vehicles can pass by during construction. An electric traction trolley arranged on the upper part of the trestle drives a support rod to move, and then the invert formwork at both ends of the support rod moves, which can greatly reduce the labor intensity of workers.

[0004] However, when this walking trestle drives the invert formwork to move through the electric traction trolley, it is necessary to first remove the blind plate, and then connect and fix the bottom of the electric trolley to the support rod through bolts. Then, when the electric trolley drives the support rod to move, the invert formwork connected to the support rod will move synchronously. However, this connection method requires frequent installation and disassembly of bolts, resulting in an increase in the construction workload and a reduction in work efficiency. To solve the above problems, a slidable invert formwork for building construction is proposed to solve the above problems. Content of the Utility Model
