Description
Technical field
The present invention relates to a kind of pecten levelling device and mounting method thereof of field, shrinkage joint, particularly a kind of comb-type bridge extension joint of bridge.
Background technology
In existing bridge expansion joint installation, adopting fixedly, the comb teeth shape stretching device of pecten and the cooperation of movable pecten is a kind of preferably, its stretching motion is finished by movable pecten, there is not vertical transition gap, thereby avoided jumping car phenomenon effectively, make vehicle smooth-going, cosily cross, disclosed in my formerly Chinese utility model patent ZL02264872.0 number " assemble comb-type bridge extension joint " and ZL02265765.7 " comb-type expansion-contraction unit with very large displacement for bridge " is exactly like this.Yet because the actual conditions of bridge are had nothing in common with each other, the installation degree of accuracy of pecten and the planeness on road surface are the difficult problems of whole erection process.
Summary of the invention
Technical problem to be solved by this invention is pecten levelling device and the mounting method thereof that a kind of comb-type bridge extension joint is provided at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the pecten levelling device of this comb-type bridge extension joint includes adjusting rod that perisporium is carved with screw thread, be threaded in the location sea whelk at adjusting rod middle part, be threaded in the installation nut of adjusting rod head and be enclosed within the outer and elastic rubber fitting between described location sea whelk and installation nut of adjusting rod.
Described adjusting rod can be simple vertical bar shaped, it also can be J-shaped, also can be combined into U-shaped by two, promptly on two arms of its U-shaped, all be carved with screw thread, and the described location sea whelk that is threaded respectively, nut be installed and be with elastic rubber fitting between described location sea whelk and installation nut.
Certainly, according to the different real needs of erecting bed, described adjusting rod can also have other compound shape.
The mounting method of the pecten levelling device of above-mentioned comb-type bridge extension joint is, at the construction field (site), take off earlier on the adjusting rod the installation nut and under the fine setting rubber cushion, preparation junction at pecten, adjusting rod is inserted the embedded bar place of bridge board and welds fixing with it with its head attitude up, according to the required setting height(from bottom) of this place's pecten, regulate the location sea whelk to suitable height, and it is itself and adjusting rod welding is fixing, outside adjusting rod, put the fine setting rubber cushion then, fluid concrete to the corresponding height and the vibration compacting of fine setting rubber cushion upper surface, when concrete is not dry and hard as yet, puts pecten, and make the head of adjusting rod pass installing hole corresponding on the pecten, screw according to the planeness needs nut (finely tune rubber cushion this moment and will have in various degree compressive strain) is installed, treat that concrete is dry and hard to get final product.
Compared with prior art, the present invention is dexterously by carrying out coarse adjustment with the location sea whelk before concrete pouring, and after the concrete pouring, dry and hard before with nut being installed and being finely tuned rubber cushion and carry out fine tuning, thoroughly eliminate being uneven of pecten after the installation that is caused because of job site and self the smooth discrepancy in elevation of pecten, thereby make bridge expanssion joint more smooth, accelerate simultaneously installation rate greatly, reduce installation cost.
