[Seismic] ball bearing hinge assessment requirements] [seismic ball bearing hinge assessment should be possible to adopt more scientific and rational evaluation of methods of mathematical statistics. As long as the strength of steel with the same ball bearing hinges finished, the same age, source materials, production process conditions and with the same ratio should be assessed using mathematical methods in order to be able to truly reflect the actual situation. The paper of the same batch beams can each hole or every two, three holes, as a number of small and medium-span bridge piles, capping beam, the number of holes can be used as a batch. The number of each batch of concrete specimens group should have too much, generally no more than 80 - 100 groups. [Seismic] As the ball joint bearing the same batch of the actual range of not more than one quarter, and the average daily temperature is less than 15 degrees is appropriate. Exceeds this range, you should not be regarded as the same batch, and were evaluated. [Seismic] ball bearing hinge assessment methods of mathematical statistics, the standard deviation S is an important parameter, since the intensity of use on behalf of the intensity of the mean value minus KS, if the strength of concrete specimens are quite different, the big S, corresponding strength representative value is smaller. So you can design seismic ball joint bearing manufacturers, [seismic] ball bearing hinge construction companies must make possible a more uniform concrete strength, namely to reduce the S value, use it as a standard to measure the quality of enterprises, should not be construction process, any additional amount of cement, otherwise it may cause multi-purpose cement, but the consequences of failure. [Seismic] steel ball bearing hinge construction is a new type of energy saving building system, known as the 21st century's "green building." Therefore, in high-rise buildings, large factories, large-span spatial structure, transportation and energy projects, residential steel buildings can play to their own advantages, and again after the Wenchuan earthquake survey shows the steel structure with strong shocks. [Seismic] ball bearing hinge mounting hinge bearing ball [seismic] if considered temporary bearing cast beam, the beam should be the strength of concrete to meet the design requirements, roof beams and remove the temporary abutment and templates, exact placement of permanent Seismic ball bearing hinge of [], [earthquake off the beam so that the ball bearing hinge force], and check whether the value of tight beam, if Void phenomenon and pre-shear deformation, timely adjustment process. According to the experience of foreign countries, China is so big, each year nearly one billion square meters of buildings, in addition to new construction, renovation of old buildings is a big amount, which requires steel counterparts, need to design, construction, supply of steel and other industries together, sum up experience, overcome difficulties, in order to move forward in the steel housing. Now good signs, overcome many difficulties. I think now steel residential development is relatively slow because, first, mechanisms, such as it is to specifically urban construction Housing Development Corporation specializes in the production of construction steel truss house with slide hinge bearings manufacturer, the design, construction, materials and full on a hinged seat, so as to reduce costs and improve efficiency. Architecture is a comprehensive industry, steel is just one part of it. The key precast beams [seismic] ball bearing hinge mounting installed precast beams [seismic] ball bearing hinge is that as much as possible to ensure the parallel beam bottom cushion and support the top surface of the stone, smooth it with [seismic ball Hinge Bearing] completely seal affixed below, to avoid bearing bias, void and non-uniform support of the phenomenon. [Seismic] ball bearing hinge again when after removal of the template, and then stuffing removed. According to the above method of construction, can stand on the beam below the bottom plate, the top surface of the pad is fully dense paste stone. At this point, it should be noted at the time of checking against sliding minimum capacity, shall be [the earthquake] contact ball bearing hinge with steel friction coefficient considered.
