[Seismic] ball bearing hinge application following the introduction of a number of steel construction steel. Such as Wuhan Railway Station, pillars is 1600 × 1400 × 30; the Guangzhou station built faster, waiting room 400 meters long and 192 meters wide; the main structure of the Shenzhen Universiade project has basically ended; Shanghai Hongqiao Airport expansion project; Nanjing South Station area of ??387,000 square meters, the use of 134,000 tons of steel, steel column Q390C; Kunming new airport; Shenzhen Stock Exchange Plaza Building, using 60,000 tons of steel steel; Henan Radio and TV Tower; Guiyang Olympic Sports Center; and the State a lot of the stadium is also used in steel Q345B; these are very large amount of steel truss drive seismic ball bearing hinge price performance, we need to traders bought steel from steel plants to process. [Seismic] ball bearing hinge installation 1. [seismic] leveling ball bearing hinge fixed: two beams of the same piece or four seat should be in the same plane seismic grid Guangrun brand ball bearing hinges for easy leveling, may, before pouring concrete in [the earthquake] and ball bearing joints between stone coat of cement mortar pad, let stand under its own weight and fixed beam automatic leveling. 2. [seismic] ball bearing hinge beam placement: Before pouring the concrete beam, usually placed in the beam at the end [the earthquake] ball bearing hinge positions require additional piece slightly larger than the size of the support bearing flat steel, steel on welded steel anchor connected with the beam. And treated as part of the supporting cast steel girder beam template were pouring concrete; in order to prevent leakage of plasma can be between the support plate and around the gap at the template with cotton, soft wood putty or tamponade. If tainted plasma phenomena, should be cleared up, so as not to affect the normal operation of bearings. [Seismic] ball bearing hinge application and installation [seismic] ball joint bearing structural system selection (1) 5 to 6 or less, can be used framework or frameworks - support system, more than 6 layers can frame support system or frame - concrete shear wall (core tube) system. Multi-storey buildings are mostly double system. (2) H-frame column has steel columns, steel concrete columns and steel reinforced concrete column, a combination of the latter two columns. In small high ball bearing hinge, composite columns than the H-type steel column province steel. (3) shear walls than steel support low ductility, low latency in a large earthquake seismic force, good ductility small seismic forces, from the anti-earthquake performance, the steel support is better than concrete shear walls. (4) steel frame - concrete shear wall system belongs to a hybrid structure, its seismic performance of the present study was not enough, not included in the seismic code, although it used more often, the choice should be careful. Core barrel is appropriate to strengthen small steel columns, but also conducive to the installation. Seismic ball bearing hinge [] in any case high quality ball bearing hinge manufacturer, does not allow the holder of two or more beams along the longitudinal centerline and licenses installed on the same bearing point; a beam in the same (or a plate on), should not be set more than two transverse bearing; different specifications of bearings should not be installed side by side. [Seismic] ball bearing hinge mounting [seismic] ball bearing hinge structure type and connection [seismic] ball bearing hinges, from the overall structure can be divided with a dust cover of 'closed' and without dust cover of "Simple", "closed" as a permanent seat in general use, "Simple" is used as a temporary stand using the slider. "Closed" and "Simple" after the completion of the mounting structure. Quality ball bearing hinge manufacturer, ball bearing hinges, rubber Guangrun project provided by Hengshui Rubber Co. Guangrun.
