Connecting adjusting structure of side formworks for road construction

Abstract

The invention discloses a connecting adjusting structure of side formworks for road construction. The connecting adjusting structure comprises a first shell, a second shell, support rods and positioning bolts. The second shell is connected to one end of the first shell. One end of a first screw is sleeved with an extrusion spring, and a second screw is connected to the other end of a connecting plate. Longitudinally-arranged threaded barrels are connected to one sides of clamping joints through fastening screws, and the positioning bolts are connected into the threaded barrels through threads.Two sets of reticulated plates are connected between the first shell and the second shell through receiving grooves, and an inflatable bag is installed between the two sets of reticulated plates. Raised heads are connected to both sides, close to one end of the concave surface, of the inflatable bag in the height direction, and the other ends of the two reticulated plates are connected into the receiving groove of the interior of one end of the second shell in a clamped mode. And the reticulated plates and the inflatable bag are connected between the two shells, so that the two shells after removal cannot be separated, and concrete cannot be leaked 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...

AI Technical Summary

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
