[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 same intensity, 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 not be too many factory outlets seismic ball bearing hinge assured purchase!, 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. Therefore, [the earthquake] 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 the construction process seismic ball bearing hinge, any increase 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 its advantages supply cheap seismic spike ball bearing hinge, after the earthquake in Wenchuan survey again shows the steel has strong seismic capacity. [Seismic] ball bearing hinge architectural design of steel structures in the whole process should be emphasized in the "conceptual design", which is especially important in the structure of the selection and arrangement of the stage. Steel structure design should be based on the overall structure of the system from the mechanical relationship between the sub-systems, damage, destruction mechanism, experimental phenomena and engineering experience in the design to get a good idea in Chengdu, Sichuan earthquake quality ball bearing hinge, making it difficult for some Exact specifications rational analysis or not specified, from the perspective of the overall arrangement and detail to determine the measures to control the structure. Seismic ball bearing hinge [] In addition, the design should be consistent with the rules so that the structural arrangement requirements, and design flexibility for thinning outer layer of elastic-plastic displacement checking. Can be based on pre-designed computer program, which according to various parts of component production standards when designing post-production assembly, will design and produce the perfect combination of rich architectural styles but also improve the efficiency of construction. [Seismic] aside ball bearing hinge hole location precision construction general requirements are as follows: 1. Design Height: + 10- 30mm 2. Negative plane position: positive and negative 20mm 3. anchor bolts verticality: 1/50 . [Seismic] ball bearing hinge upon completion of the review and amendment of the lower construction finished, not only for the abutments, piers review the size, but also in the complete process measurement inspection, the hole should be reserved for the project and determined as follows 1. long bridge distance or abutments, piers center. 2. abutments, piers center direction. 3. 4. span from the abutments, piers supporting line to the centerline distance, bearing the diagonal distance of the center of the pitch and 5 holes for the position, orientation, height, size, diameter, depth and verticality. Relations (already completed) 6. Construction segment adjacent. 7. [seismic] pad stone ball bearing hinge height and size and so on.
