[Seismic] ball hinge support environmental protection in order to achieve the purpose of green construction, first, on-site set up procedures should be required to obtain the relevant planning authorities before mobile homes, build facilities to ensure materials meet specifications, after the end of the project, choose a legal qualification Demolition temporary facilities will be removed. Secondly, the construction unit or the construction unit shall take the appropriate method, cut off groundwater into the construction area, limiting construction precipitation. Finally, we need to control the construction dust, to maintain harmony of the built environment. In addition to these, the construction unit also good green sediment transport, reduce sound, light emissions to ensure compliance with the requirements of green building activities. [Seismic] ball hinge support is related to the safety and durability of important structural component of the entire bridge structure, so usually you must ensure that the load transfer bridge bearings, deformation adaptation functions. The resulting seismic ball joint holder] [changes dysfunction and aging, mostly caused by the impact and complex factors. If you find seat change, to take early measures. Most are able to control their development and reduce the deformation function, but if the ball joint holds regardless of seismic steel bearings, ball joints bearing] [seismic deformation will become increasingly large, it will not only result in lower bearing function, and will to the upper and lower parts of the bridge structure agent very bad influence. So, pay attention to the daily inspection, regular maintenance, the timely discovery of the damage be repaired or replacement maintenance management is very important. In order to ensure [the earthquake] ball hinge support the basic functions, the first bearing design requirements should be based on proper function of the seismic ball joint bearing, predict changes in its function by gradually reducing the extent possible, the management must have a function to maintain a minimum standard provisions to ensure the maintenance and fix the standard of inspection frequency and content, and to restore the function of the management plan has been reduced, which in advance to have a sound overall maintenance management plan. [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 of ball joint seismic slip holder, 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.
