Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge engineering, in particular to a shaping template that replaces a filler for a reserved groove of a bridge expansion joint. Background Art
[0002] Bridge expansion joints refer to expansion joints that are usually set between the two beam ends, between the beam ends and the abutments, or at the hinged positions of the bridge to meet the requirements of bridge deck deformation. The expansion joints are required to be able to freely expand and contract in two directions parallel and perpendicular to the bridge axis, be firm and reliable, and vehicles should pass smoothly without sudden jumps and noise; they should be able to prevent rainwater and garbage and soil from seeping in and blocking them; they should be simple and convenient to install, inspect, maintain, and remove dirt. At the expansion joints, the railings and the bridge deck pavement should be disconnected. The function of the bridge expansion joint is to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge construction materials. Once the expansion device of the skew bridge is damaged, it will seriously affect the speed, comfort and safety of driving, and may even cause driving safety accidents.
[0003] For example, a bridge concrete guardrail expansion joint reserved slot template with publication number CN212335783U includes a plug-in hinge. The top, left, right, front and rear plates form a hollow beam concrete guardrail expansion joint reserved slot template with a rectangular lower opening. The left and right plates are arranged at a distance, and the middle of the upper side edges of the left and right plates are respectively hinged to the middle of the corresponding side edges of the top plate through plug-in hinges. The front and rear plates are respectively located between the front and rear outer sides of the top, left and right plates. The left and right plates are respectively hinged to the middle of the corresponding side edges of the front and rear plates through plug-in hinges. Pull rings are provided on the inner end surfaces of the top, left, right, front and rear plates. The utility model is a foldable and reusable reserved slot template. Although it can save time and effort to a certain extent, in actual use, the stability of the template formed by the four-way folding method is relatively poor, and it is easy to deform during actual installation, which poses a serious safety hazard. Utility Model Content
[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defects of poor template stability and easy deformation during installation in the prior art, thereby providing a shaped template to replace the filler of the reserved groove of the bridge expansion joint.

[0015] 1. The utility model provides a shaping template that replaces the filler of the reserved groove of the expansion joint of the bridge. Through the setting of the installation base plate, the overall template can be conveniently fixedly connected to the bottom of the reserved groove of the expansion joint. Through the setting of the inlay plate, the two inlay plates form an inlay groove, and the inlay groove is used to install the clamping plate and the receiving plate. This form is convenient for installing and disassembling the clamping plate and the receiving plate. Before installing the template, the clamping plate and the receiving plate are inserted from the side of the groove formed by the inlay plate. Through the setting of the side plug-in plate, the fixing plate can be conveniently installed. After the installation base plate and the receiving plate are installed, the fixing plate is inserted into the groove formed by the side plug-in plate and fixed with fixing bolts. Through the setting of the fixing holes, the installation base plate can be conveniently fixed to the bottom of the reserved groove of the expansion joint.
[0016] 2. In the technical solution provided by the utility model, through the setting of the clamping plate and the receiving plate, the clamping plate is clamped in the groove formed by the inlaid plate, and the clamping plate is fixedly connected to the receiving plate, so that the receiving plate can only make horizontal displacement along the groove to fix the vertical position. Through the setting of the fixing plate, under the action of the fixing bolts, the fixing plate and the receiving plate can be formed into a stable state so that they will not be easily displaced. Through the setting of the extension plate, the overall template and the side enclosure of the reserved groove of the expansion joint can be formed into a connection form. Through the setting of the connecting hole, the connection strength between the extension plate and the side enclosure can be enhanced. Through the opening of the threaded holes on the surface of the clamping plate and the receiving plate, the meshing action of the threads can prevent the fixing plate from tilting after installation.
