If the function of the vertical load bearing laminated rubber bearing effect on the vertical load SJQZ tensile steel ball bearings, then as shown, ball bearing with compression being squeezed out in the free side, if only rubber sheet, due to ball bearings and bearing surface friction can not see the emergence of resistance to extrusion pressure bulging linear, so spherical steel bearings, ball bearings if the following paste stiffened steel plate to prevent bulging imagine, ball bearings the only side to the outside of the bend little compression, further stiffening plate is inserted in the middle of the rubber layer to limit bending, then as a ball bearing bearing capacity will be greatly increased. When the ball bearings to withstand vertical load stiffening plate with reinforced rubber ball bearing stress state shown. Upper and lower bound rubber stiffening plate bulging BLQZ type earthquake spherical steel bearing, shear generated at the contact between the two. According tension stiffening steel produced. Tension stiffening plates produced with rubber plate thickening increases. The amount of displacement of the horizontal displacement function for horizontal displacement of the upper structure, is composed of a rubber ball bearing shear deformation absorbed, then the level of anti-force ball bearing upper and lower bearing surfaces, from ball bearings The impact of the plane shape and stiffening steel, if the shear modulus of elasticity of the rubber material to determine, size and function of the reduced shear deformation under pressure. With cement mortar with a test, adjust and determine the test should be used with the actual use of materials engineering, mortar test should be used with mechanical stirring, mixing time shall not be less than the 120s JQZ seismic damping steel ball bearings, spherical bearings by computing or look-up table of the mix is ??stirred, the consistency should be measured and the degree of their mixing layered material, when you can not meet the requirements, you should adjust the amount of material, that meets the requirements so far, and then determine the benchmark test with mortar mix when , should at least use the test with three different mixing ratio, ball bearing one of the preceding paragraph, the reference mix, ball bearings other than the amount of cement shall be with reference to increase or decrease, respectively, compared with 10% , to ensure the consistency of the qualifying conditions layered, water may be adjusted accordingly. For three different mixing ratio after adjustment, should be required to existing relevant standards molding, strength test of mortar, ball bearings and selected in line with the requirements of the test with strength and with the minimum amount of cement as manholes with ratio. Reference cement mortar mix mortar mix.
