[Seismic] ball hinge support throughout the process of architectural design in the design of steel structures should be stressed that "conceptual design", which is especially important in the structure of the selection and arrangement of the stage. In the design of steel structure should be based on the overall structure of the mechanical relationship between the system and sub-systems, damage, destruction mechanism, experimental phenomena and engineering experience obtained in the design of some of the problem is difficult to make precise specification of rational analysis or unspecified , from the perspective of the overall arrangement and detail to determine the control measures structure. [Seismic ball hinge support] In addition, the design should try to make the structural arrangements conform to the rules of the requirements and design flexibility for thinning outer layer of elastoplastic displacement checking. It can be based on pre-designed computer program, which according to various parts of component production standards for the design of post-production assembly, the perfect combination of design and production, rich architectural style, while also improving the efficiency of construction. [Seismic] aside ball bearing hinge hole location precision construction general requirements are as follows: 1. The design height: + 10- negative 30mm.2 flat position: positive and negative 20mm.3 anchor bolts verticality: 1/50 . [Seismic] ball hinge support after the completion of the review and amendment of the lower structure complete, not only for the abutments, piers size review, and the completion of the inspection process measurement, and want to set aside hole about the project is determined as follows 1. long bridge distance or abutments, piers center. 2. abutments, piers center direction. 3. 4. span from abutment, piers supporting lines to the centerline distance and bearing from the center of the pitch and 5 holes for the diagonal position, direction, height, size, aperture, depth and verticality. Relations (completed) 6. adjacent construction segment. 7. [seismic] ball joint bearing pad stone height and size and so on. Precast Seismic ball joint holder] [multi-piece T-beam axle bearing installation step 1 [the earthquake] ball joint bearing beam before lifting the ball more to the earthquake hinged bearing products, metal packaging Remove the seat and clean up rivet holder on a clean surface, then set up the stand. At the bottom of prefabricated T beam of unidirectional seismic ball joint bearing products, on a support plate embedded steel beam bottom and not be a gap, if the gap should be filled way to take pressure grouting. 2 [seismic ball bearing hinge support] chiseling stone in place parts of the bearing pad surface, remove the reserved hole in the debris, and the support pad stone surface water wet. 3. [seismic] ball bearing hinge shape, T beam falling girder in place after the earthquake ball joint bearing guide finished, adjust seat position and elevation to the design. After the implementation in place, with falsework (or skid) Retaining both sides of the beam, the beam prevent roll. [4] Seismic ball hinge support multi-plate girder installation time T, the line should be at the center of two lifting T girder. And, after the two-piece T beam hoisting, timely seismic welding two pieces of steel ball joint connection between the T beam support products, followed by the rest of the piece T hoisting beams symmetrically from the center to the sides. After each piece T beam in place, set up a temporary support, and timely soldering the corresponding connection reinforcement. [5] Earthquake ball bearing hinge between the transverse bulkhead concrete T beam multi-piece casting and after reaching the intensity, timely removal bearing temporary locking connection means. And installed bearing panels. Seismic ball bearing hinge [] Is there some bearing, can be shared by the pier level of force? You can use rubber bearing basin + laminated rubber bearing manner in all piers are set laminated rubber bearing vertical force borne by the rubber bearing basin, the horizontal force from the rubber bearing basin and laminated rubber bearings shared, E1 lower rubber bearing basin to meet the requirements of the requirements under the E2 can be cut bad, E2 equivalent horizontal force by the basin rubber bearing laminated rubber bearing friction and shear shared.
