The present invention between the beam of the bridge and the upper plate supported by the bottom of the beam joint and the lower plate fixed with an anchor bolt on the upper end of the bridge. The present invention relates to a shoe bearing bearing cover for covering a shoe bearing outside the shoe bearing.

In detail, when forming the upper plate and the lower plate, it is formed by pre-punching a plurality of landing holes in the periphery of the upper plate and the lower plate. Apply the liner paste on one side of this inner and outer cover in the same direction. "Shape in shape.

And again with adhesive bands and holes "B" and "-" shaped metal bands are attached to the upper and lower edges and the periphery of the shoe bearings in sequence, and the bolts are screwed into the holes and anchoring holes so that the inner and outer covers are covered with the outside of the shoe bearings. By doing so it is possible to protect the life of the shoe bearing semi-permanently.

The protective cover of the present invention is formed by the support frame of the synthetic resin material coupled by the fitting hole of each end in the inner edge portion of the inner bottom protective cover formed of a waterproof cloth as shown in the drawing rotation and horizontal movement And forward, backward, left and right movements, and The inner side of the protective cover was opened with a support frame so that the inner surface of the cover was not abutted with respect to the shoe bearing which performs the function of the upper and lower light beams.

The purpose of covering the bearings in this way is to protect them from various oxides that invade from the outside so that the bearing plate composed at the center of the upper plate and the lower plate as well as the semi-permanent action can be semi-permanently. To give.

As is well known, the bearing is installed between the beam of the bridge and the upper plate on which the beam joint is placed, and also the lower plate fixed to the upper part of the bridge by anchor bolts. The general effect as described above is performed.

However, since they are generally formed from a metal of a highly oxidation-resistant casting material by moisture, salt, and other oxides, it is difficult to carry out such a function semi-permanently continuously, and it is a decision that poses a danger to the safety of the bridge. There was this.

In particular, when the upper and lower plates as well as the shoe bearings between them are easily corroded by foreign substances and have problems in operation, economical losses and work difficulties that need to be replaced by other materials also entail problems that cannot be easily performed without replacement. do.

Therefore, in the present invention, in order to semi-permanently protect them from the oxides invading from the outside, the inner cover and the outer cover of the waterproof cloth and the synthetic resin cloth are formed on the upper and lower periphery layers, and the adhesive band of the rubber sponge material The metal bands are connected in sequence to produce upper and lower beams from the upper edge to the lower edge.

In addition, the protective cover installed in this way is formed in the inner edge of the inner cover of the support frame formed of synthetic resin in order to prevent the inner surface of the protective cover from abutting the shoe bearing by the pressure (wind pressure) applied from the outside. It is fitted in each end of the support frame to maintain the gap between the inner surface of the protective cover and the shoe bearings, and in one direction of the inner and outer surface covers. "Shaped slider fasteners were formed so that the safety of the shoe bearings could be easily opened and closed when needed.

Referring to the present invention in detail according to the accompanying drawings as follows. In the structure for protecting the bridge shoe bearing 2 consisting of the upper plate 1 and the lower plate 1 ', a plurality of upper and lower plates 1, 1', and peripheral portions 3, 3 'are provided at regular intervals. Inner and outer cover formed by pre-drilling the hole (4) (4 ') and forming the adhesive band (5) (5') of rubber sponge material, waterproof cloth and synthetic resin cloth sequentially from the peripheral part (3) (3 '). (6) (6 ') in layers, and then the outer surface of the rubber band with adhesive bands (7) (7'), long holes (8) (8 ') and retention holes (9) (9') " The metal bands 10 and 10 'of the "-" and "-" shapes are attached to each other so that the inner and outer surface covers 6 and 6' have upper and lower portions A and B, respectively, with the upper plate 1 and the lower plate 1 '. The bolts 11 and 11 'are rolled on the periphery 3 and 3', and at the same time, each end of the support frame 12 and 12 'is made of a synthetic resin into the inner cover 6 at the same time. The inner and outer cover 6, 6 'is installed on the outside of the shoe bearing 2 in the form of upper and lower beams so that the fitting holes 13, 13' are fitted and supported at the corners 14, 14 '. Formed in one surface direction of the cover 6, 6 '; The cover 6 and 6 'can be opened and closed by the " shaped slider fasteners 15 and 15'.

Reference numerals 16, 16 'denote adhesives, 17, 17' denote beams, and 18 denote piers.

The working effect of the present invention configured as described above is the upper and lower portions (A) and (B) of the inner and outer surface covers 6 and 6 'installed on the upper plate 1 and the lower plate 1' periphery 3 and 3 '. Apply the adhesive bands 5, 5 ', 7 and 7' of the sponge material to the inner and outer surfaces thereof, and then back to the outer surface of the adhesive bands 7 and 7 'of the rubber sponge material. Metal bands (10) and (10 ') of "shaped" and "一" shaped, and then bolts (11) (11) fitted with perforated long holes (8) (8') and landing holes (9) (9 '). ') And the bolts 11, 11' are firmly held toward the landing holes 4, 4 'formed in the periphery 3, 3', so that the inner and outer cover 6, 6 The upper and lower parts (A) and (B) of ') are covered to effectively protect the outside of the shoe bearing 2 by the state of being stuck to the upper plate 1 and the lower plate 1' periphery 3 and 3 '. .

Therefore, it is possible to prevent the corrosive action of the shoe bearing 2 from oxidizing corrosive substances invading from the outside of the shoe bearing 2, for example, leaks between the beam and the beam or salt and moisture caused by sea wind. In addition to extending the life of the cover, the cover (6) (6 ') from the outside of the shoe bearing (2) by the action of the rotation and horizontal movement and the fixed and internal pressure, and the action of PTFE, etc. When the support frame 12, 12 'in preparation for the pressure (wind pressure) applied to the inner surface is supported by the corner portions 14, 14' by the fitting holes 13, 13 'at its ends, respectively. Since the cover 6 is opened so as not to directly contact the shoe bearing 2, the support frames 12 and 12 'are respectively prepared for the pressure (wind pressure) applied to the inner and outer surface covers 6 and 6'. Open the inner cover 6 so as not to directly contact the shoe bearing 2 in a state supported by the corner portions 14 and 14 'by the fitting holes 13 and 13' at the ends. The semi-permanent effect on the lifespan of the inner and outer surface covers 6 and 6 ', as well as the inner and outer cover 6, 6', "Effect that the slider fasteners 15, 15 'of the shape-shaped slider can be easily opened and closed as needed, so that the safety of the shoe bearing 2 can be easily inspected. To provide.
