2018-08-13

On the general plate rubber bearing equipment cast-in-place beam equipment rubber bearing is more convenient. The construction procedure is as follows: the top surface of abutment pad stone shall be clean. If the bearing pad stone elevation interval is too large, can be adjusted with cement mortar. The center shall be marked on the bearing pad stone according to the planning drawing, and the center of the rubber bearing shall be consistent with the center line of the bearing pad stone during equipment, so as to ensure the bearing in place accurately.

When the same piece of beam needs two or four bearings, in order to facilitate leveling, a layer of cement mortar can be laid between the bearing pad stone and the bearing, so that the rubber bearing can be automatically leveled under the pressure of the bridge body. Before pouring the beam body, a supporting steel plate slightly larger than the support plane is placed on the support, the steel plate is welded with the anchor steel bar to connect with the beam body, and the supporting steel plate is regarded as a part of the pouring beam template for pouring. According to the above method, the support can be closely attached to the steel plate at the bottom of the beam and the top surface of the pad stone.
Equipment for precast beam rubber bearing: The key to good equipment for precast beam rubber bearing is to ensure that the bottom of the beam is parallel and flat on the top surface of the pad stone, so that it is closely attached to the upper and lower surfaces of the bearing, and there is no phenomenon of bias, void and uneven bearing force. The construction procedure is as follows: handle the support pad stone and make the support pad stone elevation together. The bottom surface of the precast beam in contact with the bearing shall be level and flat.
When there is honeycomb slurry and inclination, it should be tamped and leveled with cement mortar in advance. The correct location of the rubber bearing shall first make the bearing and bearing pad stone accurately in place according to the planning requirements. When the beam is erected and dropped, the longitudinal axis of the T-beam coincides with the center line of the support; the longitudinal axis of the plate beam and box beam is parallel to the center line of the support.
