Description

TECHNICAL FIELD

[0001] The utility model relates to bridge expansion joint field, concretely relates to a bridge expansion joint rubber strip installation clamping tool. BACKGROUND

[0002] Bridge expansion joint is a structure set to meet the requirements of bridge deck deformation, usually between two beam ends, beam end and abutment or hinge position of bridge, mainly adjusting the displacement and connection between superstructure caused by vehicle load and bridge building materials. Among them, E-type expansion joint is a common type of bridge expansion joint. Mainly composed of profile steel and E-type rubber strip. Profile steel is generally a specially designed and processed metal structure, used to provide support and fix the rubber strip, and bear the load of vehicles. E-type rubber strip is installed inside the profile steel, which is the key part to realize expansion and sealing function. Its shape design makes the expansion joint effectively adapt to the expansion deformation of the bridge in both transverse and longitudinal directions. The structure of E-type can better fit the expansion joint space and closely cooperate with the profile steel, and the E-type rubber strip can effectively prevent water, dust and small particles from entering the expansion joint, which protects the internal structure of the bridge. It can adapt to the expansion requirements of various types of bridges, whether it is a small bridge or a medium-sized bridge, the appropriate E-type expansion joint can be selected according to the actual expansion amount.

[0003] At present, when installing the expansion joint rubber strip, one end of the rubber strip is inserted into one end of the profile steel, and then the other end is stretched to make it smooth into the gap of the profile steel, and then a crowbar or other tool is used to move the top of the rubber strip to embed it into the groove of the profile steel. When using a crowbar or other tool for installation, if the operation is not proper, such as using too much force, it is easy to cause scratches and damage to the surface of the rubber strip, affecting the service life and sealing performance of the rubber strip. Moreover, when using a crowbar or other tool to install the rubber strip, it is necessary to install one side first and then the other side, which makes the entire installation process become two relatively independent stages. Each time one side is installed, the tool position needs to be adjusted and the installation starting point needs to be determined again, which consumes more time in the installation process and leads to low installation efficiency.
