A connection adjustment structure of side formwork for road construction

Abstract

The invention discloses a connection adjustment structure of a side formwork for road construction, which comprises a first shell, a second shell, a support rod and a positioning bolt, one end of the first shell is connected with a second shell, and the first shell is connected with a second shell. One end of a screw is fitted with an extruding spring, the other end of the connecting plate is connected with a second screw, one side of the clamping joint is connected with a longitudinally arranged threaded cylinder through a fastening screw, and the inside of the threaded cylinder is connected with a positioning bolt through a thread . There are two groups of net plates connected between the first housing and the second housing through the receiving groove, and an inflatable bag is installed between the two groups of the net plates, and the inflatable bag is close to the concave shape. Protrusions are connected to both sides of one end of the surface along the height direction, and the other ends of the two mesh plates are snapped into the receiving groove inside the one end of the second housing through the side plate. The mesh plate and the air bag are connected between the two shells, so that the two shells will not be separated after disassembly, and the concrete will not leak between the two shells.

Description

technical field [0001] The invention relates to an adjustment structure, in particular to a connection adjustment structure of a side formwork for road construction. Background technique [0002] With the continuous development of the economy, the country pays more and more attention to the road and traffic conditions in rural areas. Start building cement roads on dirt roads in the countryside. During the construction of the cement road, in order to make the difference in the width of the road surface small, and the height of the road surface relatively even, the two sides are in a horizontal state. Side formwork is often installed on both sides of the roadbed before pouring concrete to limit the position of the concrete and squeeze the concrete to ensure that the quality of the road built is better. [0003] But the existing side formwork for road construction still has certain deficiencies in use. The adjustment structure of the existing side formwork is inconvenient to...

Problems solved by technology

[0004] The purpose of the present invention is to provide a connection adjustment structure of side formwork for road construction, which can solve the problem that the traditional side formwork cannot be changed with the slope and curvature of the road.

It is easy to leak when the concrete is poured, and the safety performance is not high
