Connector unit of steel frame and connection method

Abstract

The invention relates to a connector of steel support, which comprises: a connector and an adjusting tile. Wherein, one end of connector has a positive arc head (2) whose outer side is connected to the anchor plate (8), and another head has a passive arc head (1) whose outer side is connected to the anchor plate (8); the concave and convex surfaces of adjusting tile are both arc surface, while the positive arc head (2) is the convex surface and the passive arc head (1) is the concave surface, with the same diameter. The method comprises: inserting the positive arc head (2) into the passive one, which are connected by using connecting bolt through the anchor plate (8). And by adding adjusting tile (7) between positive arc head (2) and passive arc heads (1), the adjustment can be realized. The invention has simple operation and adjustable longitudinal arc without displacement.

Description

technical field [0001] The invention relates to a support device for civil construction, in particular to a joint device and connection method for a steel frame structure used for arch bridge construction. Background technique [0002] The joint device connecting the steel frame and the steel frame is a structure often used in engineering, such as the connection of each segment of the bridge arch support, the connection of the longitudinal beam support of the bridge erecting machine, the connection of the gantry, the connection of the frame construction platform, etc. . In the construction of arch bridges, the steel arch frame is usually connected by pins in the prior art, which is more convenient, but there is generally a gap of about 0.1 to 0.5 mm between the pins and the pin holes, which makes the assembly accuracy relatively poor, and the steel arch frame Lateral stability also has a certain influence, and more wave and wind ropes must be added to maintain the stability...

Problems solved by technology

In the construction of arch bridges, the steel arch frame is usually connected by pins in the prior art, which is more convenient, but there is generally a gap of about 0.1 to 0.5 mm between the pins and the pin holes, which makes the assembly accuracy relatively poor, and the steel arch frame Lateral stability also has a certain impact, so more wave and wind ropes must be added to maintain the stability of the arch bridge

For arch bridges with different spans, connecting plates or connecting rods of different specifications are often used in the prior art in order to adjust the arch spans and arcs. These processed parts will have slight differences due to differences in spans and heights. In different cast-in-place constructions It cannot be used universally, which increases the construction cost and causes great waste
