As a means to solve the problem, although you can consider using function-separated type bearings, highway bridge bearing systems occasions, constitute fixed bearing at the highway bridge bearings, main bearings and must be set for vertical withstand a main lower beam horizontal seismic forces is provided in both types of bearings recovery means under the bridge. So if compared with the conventional structure of the bridge must be strengthened, highway bridge bearings single base due to an increase in the scope of the mounting portion fixed bridge abutment, so ease of construction and other aspects of providers worried. A rotational displacement can be separated from the constraints arising out of the ordinary rubber bearings, but will it be implemented within the same highway bridge bearing structure, to increase the degree of freedom of the seismic design purposes, even if the construction can also be used with the conventional construction method different forms bearing, the effect of this highway bridge support structure of the program, as shown constructed in accordance with the conduct, highway bridge bearing hybrid bearing has the following main features pot rubber fixed bearing Since the rotational displacement of the rubber bearing is separated, thereby defining the shape of the improved degree of freedom in the design cycle and optionally also possible. Seismic reinforcement while constrained by the space in the case of clear, the elastic limit may be used to improve the method sets the rubber stiffness. Can be generated when the control functions and seismic deformation. The relationship between highway bridge bearing installation should be noted that the installation of the upper structure, namely longitudinal bridge, the lower edge of the beam width, thickness and processing the positional relationship between the firmware and bearing mounting bolts and bolts length. Relations with the lower structure installation, that contact with the skew bridge parapet state highway bridge supports full-height display, roads and bridges and bridge abutment contact surface edge distance, and adjacent structures installed relations, namely on the pier mount installation, When the relationship between the width and length restrictions, and adjacent structures installed on the pier road and bridge bearing pedestal installation, bridge width and length restrictions. Relationship with anti-fall beam apparatus and telescopic device, and supports, to prevent displacement of the beam off the device and may telescopic device relationships, it is generally desirable to prevent displacement of the bearing is less than the amount of displacement of the beam off the device and telescopic device, etc., roads and bridges bearing anchor bolts should pay attention to. For the length of the anchor bolt, the general provisions of bridge design specifications must be difficult to guarantee the role of anchor bolts, so the use of more than 25mm diameter anchor for seismic ball fixed bearing, highway bridge bearings using the number on the anchor bolts, span bridge abutment wish to use two smaller, even the big span bridge also want to control the six it. About fixed bearing bridges, highways continuous cold end fixed bridge bearings, in order to resist earthquakes along the horizontal force along the bridge. Fixed bearing, excellent quality manufacturer, seismic ball joints fixed support provided by Hao-engineered rubber. Hengshui HaoTong Engineering Rubber Co., Ltd.
