A construction method of a bridge-assembled expansion joint device

Abstract

The present application relates to a construction method of a bridge assembly type expansion joint device, which includes the following steps: Step 1. A temporary support is built between the ends of two adjacent beams that are used to build the bridge and are close to each other. The temporary support includes a support plate and a bridge. The two baffles are respectively arranged on the opposite side walls of the support plate. The two ends of the support plate respectively extend to one end of the two adjacent beams. To limit the support plate from the positioning piece of the beam body; Step 2, pour concrete on the upper surface of the beam body to form a concrete bridge deck, and the beam body area corresponding to the support plate forms a reserved groove for installing the expansion joint device; Step 3, Concrete solidification And after the maintenance is completed, when it is necessary to install the expansion joint device, cancel the positioning of the positioning piece to the support plate, remove the support plate, clean the reserved groove, and then install the expansion joint device in the reserved groove. This application has improvement related The effect of the negative effects brought about by slotting in the technology.

Description

technical field [0001] The present application relates to the field of expansion joint devices, and in particular, to a construction method of a bridge-assembled expansion joint device. Background technique [0002] At present, on large bridges, multiple expansion joint devices are generally set to adjust the displacement and connection between the superstructure caused by the vehicle load and the bridge building materials, so as to reduce the probability of safety accidents. [0003] The construction process of the expansion joint device in the related art is as follows: 1. Make a slot at the reserved gap between two adjacent beams, and deal with the sundries in the slot and the gap; 2. Straighten out the reserved steel bars in the slot; Install the expansion joint device in the groove, and weld the reserved steel bars on the expansion joint device and the reserved steel bars in the groove firmly; 4. Pour concrete in the area where the steel bars in the groove and the reser...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that in the related technologies, in order to ensure the stable installation of the expansion joint device, the expansion joints are generally treated after the bridge deck concrete is paved and hardened. At that time, since the pavement has been laid, it is necessary to use a cutting machine to cut grooves on the concrete bridge deck. On the one hand, dust will pollute the environment, and on the other hand, the cut concrete needs to be processed, which is time-consuming and laborious.
