Description
Technical Field
The utility model relates to a bridge expansion joint device especially relates to a height-adjustable bridge expansion joint device of no concrete.
Background
The bridge engineering is influenced by vehicle load, creep generated by the influence of air temperature on the materials of the bridge, wind power and the like in the operation process, so that the bridge contracts, stretches and deforms. The expansion joint is a structural joint which is arranged for preventing the structure of a building component from cracking or damaging due to climate temperature change (thermal expansion and cold contraction), and a comb plate expansion device is required to be installed at the structural joint for ensuring the safety of personnel and driving. The expansion device is one of important functional components of bridge engineering, and in order to meet the requirement of bridge deformation, the expansion device is usually installed between bridges and between bridge abutments. At present, the bridge expansion joint device is not adjustable in height, is more suitable for being used after a paving project is finished, and then enters a field to install the expansion joint device, so that the construction period can be influenced by a plurality of factors. Therefore, there is a need for a height adjustable bridge expansion joint device, which can be installed first and then paved.
Disclosure of Invention
The utility model aims to solve the technical problem that a but quick installation and height-adjusting's no concrete bridge expansion joint device is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a no concrete height-adjustable bridge expansion joint device, includes two fishback that mutually support and use, still includes being used for the installation that two symmetries set up fishback's fixed bolster, the fixed bolster pass through welded connection by the crashproof baffle of 1 style of calligraphy and the support backing plate of L type and form h type structure, crashproof baffle pass through the dowel and be connected with the pre-buried reinforcing bar of roof beam end, the fishback pass through bolted connection spare to be fixed the horizontal part of support backing plate on, the fishback with the horizontal part of support backing plate between be provided with and transfer high layer, two the vertical part of support backing plate between the anchor be connected with U type waterstop.
The bolt connecting piece include check bolt and hexagon nut, check bolt pass in proper order the fishback the rising layer with the horizontal portion of support backing plate with hexagon nut fastening connection, hexagon nut weld the bottom of support backing plate.
And a cover plate is arranged on the upper surfaces of the two comb plates. Can prevent sundries from falling into the water stop.
The bottom of the comb plate is positioned between the two heightening layers, and a dustproof plate is arranged between the two heightening layers.
The upper surface of the comb plate is provided with an anti-skid groove. Can effectively prevent slipping.
The height-adjusting layer is made of a rubber canvas plate.
Compared with the prior art, the utility model has the advantages of: the utility model relates to a height-adjustable bridge expansion joint device of no concrete can reach the designing requirement according to the mounting height that on-the-spot actual conditions adjusted the fixed bolster through the anchor rod. The comb plate is installed on the fixed support through the anti-loose bolts and the hexagon nuts. After construction, a cover plate is additionally arranged, so that sundries are prevented from entering the expansion joint device during paving. After paving and constructing, tear open the apron, adjust the height of fishback through the layer of increaseing, reach and spread the layer upper surface and level. The expansion joint device can be installed before asphalt is paved, and has the advantages of quick installation and adjustable height.
