Front seat can be installed out of the box to check the packing list, including parts lists, copies of inspection reports, bearing product certification secretary install conservation rules, the construction unit shall be arbitrarily rotated after unpacking coupling bolts, and one shall be arbitrarily disassemble bearing, Supports mounting height should meet the design requirements, to ensure that the level and smooth bearing plane. Supports four hinge bearing surface height difference should not be greater than 2mm. Installation and precautions ball bearing. Concrete grade beam bridge and part of the field should not be less than tons C40, special circumstances require approval by the design unit. When installing bearings, bearing plate should be in the next four weeks to adjust the bearing steel template level, and lower bearing plate above the bottom surface of the top face 20-50mm pier bearing vertical and horizontal lines to identify the location of the seismic slip bearing ball joints, to conform to the design requirements. Filled with epoxy mortar seat cushion underside, foreign general installation method, commonly used epoxy mortar mix. After hardening epoxy resin mortar, eradicate temporary steel wedge bearing corners and fill the position of the wedge is drawn with epoxy mortar. After the installation is completed after the end of the beam bi-slip stand, or in-situ concrete beams formed a whole and to meet the design strength before tensioned prestressed beam, the removal, under the seat plate to prevent the beam normal constraints rotation. Oil coating is polymerized oil Sliding bearing, catalysts and pigments, etc., the coating during the drying process by automated fatty acid carbon chain of the unsaturated double bonds on the polymer, to refer to a body structure so that a film is cured, the domestic manufacturer more varieties of protective coatings on the market there are many different characters, conditions and requirements vary, we can say the market can not find a universal paint, so choose paint material is very important, but as a kind of melancholy Anti-corrosion coatings must have the following performance characteristics. Characteristic has good resistance to corrosion, refers to the corrosive media which it contacts the cured massacre in terms of physical and chemical properties are stable, neither corrosive medium swelling, dissolution, decomposition and destruction of the one-way slip bearing, that is to say sub-corrosive harmful chemical reactions. Having a small air permeability and water permeability, gas-impermeable and permeable coatings no absolute, it is necessary to select a small permeability shielding film material and the type of coating large. Good character focus and the necessary mechanical strength, smear can firmly leaning in protective basically, is a manifestation of its ability to play a protective role of key factors, should also have certain physical and mechanical strength to withstand at work stress conditions.
