Fixed fishback mounting structure of bridge expansion joint device

Technical Field

The utility model relates to a bridge expansion joint device, in particular to a fixed comb plate mounting structure of the bridge expansion joint device.

Background

At present, bridge expansion devices used in bridge engineering have a plurality of structures, and comb-tooth type bridge expansion devices are common among the bridge expansion devices. For the comb-tooth type bridge expansion device, in order to ensure the bearing and anti-deflection performance of the comb-tooth part of the device, each comb tooth in the comb-tooth structure needs to keep a certain width size, and because the comb teeth are distributed in a mutually staggered manner, the gap between the comb teeth is also larger, so that the problem brought about is that wheels may sink into the gap between the comb teeth when a non-motor vehicle (particularly a narrow-wheel type bicycle or electric vehicle) passes through, and the driving safety is influenced. In order to prevent that the wheel of non-motor vehicle from getting into the clearance of broach, generally carry out structural improvement through the clearance that reduces adjacent broach at present, but, along with the broach clearance is littleer and more, in order to guarantee driving safety, also higher and more high to the installation requirement of fixed broach.

Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

The first embodiment is as follows:

as shown in fig. 1 to 4, in the fixed comb plate mounting structure of this embodiment, the beam end portion 1 corresponding to the fixed comb plate 2 is provided with the embedded steel bars 3, the mounting notch of the beam end portion 1 is provided with the concrete layer 10, and the upper portion of the embedded steel bars 3 is arranged in the concrete layer 10. A bottom plate 4 is fixed below the fixed comb plate 2, and the bottom plate 4 is horizontally distributed between the concrete layer 10 and the fixed comb plate 2.

In this embodiment, the bottom plate 4 is fixed with the fixed comb plate 2 through the connecting bolt 7, and the connecting bolt 7 penetrates through the bottom plate 4 from bottom to top and is connected to the fixed comb plate 2. Be equipped with first bracket bolt 5 in concrete layer 10, the lower extreme of first bracket bolt 5 is connected and is fixed on embedded steel bar 3, and the upper end of first bracket bolt 5 is fixed on bottom plate 4 through first nut 6.
