Detailed Product Description: | Load-bearing beams of change in these matters before formal testing Shaanxi wall beams change, should make a trial-loading test, load value can be estimated failure load of 10%, change in the wall beams, girders change to do so primarily to Check the test system is flexible and reliable, as well as on the change in the beam, the lower bearing plate in contact with the groove between the masonry is uniform and dense. At the same time these changes when the beam before formal testing should also be staged loading. Each stage of loading advisable estimated failure load of 10%, should be uniform added over 1-1.5min, then keep the pressure 2min. Beam load change added to the estimated failure load of 80%, the loading rate should be scheduled to continue loading Shaanxi change wall beams trust between the slot until the masonry damage. Change wall beams, girders change, hit the post and if masonry cracks between the trough and the increase in the rapid expansion of the facade of the supermarket, the oil pressure gauge pointer obvious fallback when the limit is reached between the state trough masonry. Wall to change the course of this testing process Liang Shaanxi change wall beams companies should carefully observe the situation changed between the initial beam base slot masonry cracking and crack development and oil pressure gauge readings recorded under each stage of loading, the crack with load conditions change and so on. If the slot between the masonry bearing surfaces due to poor contact and showed partial pressure or eccentric compression state before the changes found in the Shaanxi Liang Liang team to change the wall should stop testing, adjusting the test device and re-test; can not be adjusted, should Replacing the measuring point. No matter what kind of load-bearing walls to change the beam, the beam on both sides of the pillars are to have a high strength to withstand. In the column under pressure when there are two cases, one is the axis of compression, and the other is eccentric compression. In the brick and concrete structure, a single reinforced concrete pillars is usually used as the framework of the post. Such beads moment it is very small. Axial compression columns and pillars endurance, he not only related to the size section, still have a great relationship with the material and the degree of slender pillars. An elongated column is the degree of their length and width ratio expressed. Is called the column "slenderness ratio", which slenderness ratio increases, indicating that the smaller its endurance. Shaanxi wall beam technology change | change Liang Shaanxi Wall | Wall change Liang Xin Li's latest offer by Xin Li Nanyang wall beams provide change.
