Node structure node structure [seismic] application ball bearing steel hinges directly affects the amount of steel, concentrate on solving the node practice in two locations in the pilot house. (1) part of the pilot project rooting column foot basement structure by reinforced concrete frame - shear wall structure considerations, pedestal located in the basement level of the roof, the column foot with embedded steel roof connection with high-strength bolts. Supermarket bag with reinforced concrete ground floor by steel reinforced concrete columns frame - reinforced concrete shear wall structure seismic considerations finished fixed hinge bearing type, the second floor above the steel frame - reinforced concrete shear wall structures. (2) steel beam steel frame and reinforced concrete shear wall (core tube) connection in order to ensure the safety and reliability of pilot projects, the design does not use a simple connection method embedded steel in the shear wall, but in shear ends and the core barrel at the corner from the column foot elevation since Ⅰ core set down through the column, and at the height of the steel girder steel truss columns as lateral connections between the core and the core columns to ensure that the parts of the node working conditions and calculation assumes coincide. If you can not be expected to be installed at the time of the annual average temperature, but also can design selection [seismic] ball bearing hinge rubber bearings when appropriate to increase the height of an easy way to handle bearing ball bearing hinge finished fixing, which is in the extreme high and low temperature When installing, make sure to consider the amount should be higher when the maximum displacement of the upper structure, pre-cut low-temperature deformation impact of the need to increase the amount of displacement into account, consider selecting [seismic] ball bearing hinge rubber bearing rubber layer required total increases in thickness. This can be installed in any temperature conditions rubber bearings, the maximum shear deformation can be controlled within the allowable range, without the need for additional special construction methods. However, if [the earthquake] rubber bearing ball bearing hinge to the desired height and can not meet the bridge design specifications, we can use tetrafluoroethylene skateboard rubber bearing Lai adapt. [Seismic ball bearing hinge [seismic] how to make steel ball bearing hinge construction quality control] [earthquake] ball bearing hinge works well before the start of the preparatory work (1) to strengthen the work of construction drawings joint trial. Construction drawings are the basis for the finished product fixed hinge support, the project started before the project control mechanism to organize the control personnel familiar with engineering drawings and project standards, technology condition, fully understand the design intent. (2) a careful review of the installation of steel construction design. Construction design is a comprehensive guide project implementation and construction units of technical documents, and improve the degree of construction design directly affects the quality of the project's progress. Therefore, the fixed hinge bearing basin finished, [seismic] steel ball bearing hinge installation construction organization design review to be targeted and focused. Review of the key elements are: a quality assurance system and technology management system; b special types of training certificates and appointment cards; c application of new technology; d for projects targeted; e quality..... progress control measures and methods; f construction plan (schedule) arrangements. 2.2 Strengthening site construction process quality control [seismic] ball bearing hinge connecting the upper and lower plate and bridge structures: 1. Connect under seismic steel ball bearing hinge "closed", and can be in the pier (Taiwan) support cushion reserve pits corresponding stone, under former steel girder with epoxy mortar bond in the pits can be.
