Abstract
The utility model discloses a novel adjustable expansion joint device for a bridge and relates to the technical field of bridge equipment. Second deformed structural steel is arranged on the left side of first deformed structural steel, a V-shaped rubber strip is arranged at upper ends of inner sides of the first deformed structural steel and the second deformed structural steel, strong spring sare arranged in a center connecting position of the first deformed structural steel and the second deformed structural steel, and two ends of the first deformed structural steel and two ends of the second deformed structural steel are connected integrally through anchor bolts and tightening nuts. The expansion joint device is simple in structure, reasonable in design and convenient to operate, two pieces of structural steel of the expansion joint device are connected through the anchor bolts, a plurality of strong springs are arranged between the two pieces of structural steel, and the adjustability of the distance between the two pieces of structural steel is realized by the aid of the anchor bolts and the strong springs, so that workers can use the expansion joint device conveniently during on-site construction.
Description
Technical field
The utility model relates to bridge equipment technical field, is specifically related to a kind of novel adjustable apparatus of expansion joint for bridge.
Background technology
Bridge expanssion joint refers to the requirement for meeting bridge floor distortion, conventionally between two beam-ends, shrinkage joint is set between beam-ends and abutment or in the articulated position of bridge.Require shrinkage joint parallel, perpendicular to the both direction of bridge axes, all can free-extension, solid and reliable, Vehicle Driving Cycle out-of-date should be smooth-going, without kick and noise; Want to prevent that rainwater and rubbish earth from infiltrating obstruction; Installation, inspection, maintenance, elimination dirt are all wanted simple and convenient.Shrinkage joint place is being set, and railing and deck paving all will disconnect.
Existing apparatus of expansion joint for bridge generally has dock, steel supporting type, combined shear formula (board-like) and modulus supporting type etc.
Existing expansion gap device in use, between two shaped steel at formation shrinkage joint, distance is certain, normal is all distance between determining before production, then use anchor rib anchoring moulding, such expansion gap device is in the time constructing, and the distance between shaped steel and shaped steel can not change according to on-the-spot situation.
Summary of the invention
The purpose of this utility model is to provide a kind of novel adjustable apparatus of expansion joint for bridge, it is simple in structure, reasonable in design and easy to operate, two shaped steel of expansion gap device connect by anchor bolt, and several brute springs were set before two shaped steel, utilize anchor bolt and brute spring to make two distances between shaped steel realize adjustability, workman's use while better facilitating site operation.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises the first profiled bar 1, the second profiled bar 2, V-type rubber strip 3, brute spring 4, anchor bolt 5, clamp nut 6 and reinforcing through hole 7, the left side of the first profiled bar 1 is provided with the second profiled bar 2, the inner top side of the first profiled bar 1 and the second profiled bar 2 is provided with V-type rubber strip 3, the junction, center of the first profiled bar 1 and the second profiled bar 2 is provided with brute spring 4, the two ends of the first profiled bar 1 and the second profiled bar 2 connect as one by anchor bolt 5 and clamp nut 6, the both sides of the first profiled bar 1 and the second profiled bar 2 are provided with several reinforcing through holes 7.
The utility model operating principle: the upper end of the first profiled bar 1 and the second profiled bar 2 is carried out drainage by V-type rubber strip 3 by rainwater, in the time that being installed, expansion gap device utilize anchor bolt 5 and clamp nut 6 to adjust the distance between the first profiled bar 1 and the second profiled bar 2 according to on-the-spot situation, and distance between further controlling by the brute spring 4 between the first profiled bar 1 and the second profiled bar 2, through hole 7 is reinforced in expansion gap device utilization makes the first profiled bar 1 and the second profiled bar 2 better connect as one with pontic.
The utlity model has following beneficial effect: it is simple in structure, reasonable in design and easy to operate, two shaped steel of expansion gap device connect by anchor bolt, and several brute springs were set before two shaped steel, utilize anchor bolt and brute spring to make two distances between shaped steel realize adjustability, workman's use while better facilitating site operation.
