AI Technical Summary
The steel sections of the existing bridge expansion joints are exposed on the bridge surface, which is inconsistent with the park landscape. The construction period is long and vehicles experience bumpy rides. There is also a large difference in stiffness between the rigid expansion joints and the road surface.
The bridge deck pavement layer is laid by filling the interior of prefabricated U-shaped iron with neutral silicone and fixing the left and right prefabricated steel sections by welding or bolting, thus forming an L-shaped structure. This simplifies the construction process and allows for greater deformation.
It solves the problem of unsightly steel expansion joints, shortens the construction period, improves vehicle comfort, and reduces bumps.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0021] Please refer to Figs. 1-3 The utility model provides a telescopic structure of park landscape bridge, which is characterized in that an abutment back wall 1 is arranged in the landscape bridge, a main beam 2 is arranged on one side of the abutment back wall 1, and an expansion joint 3 is arranged between the main beam 2 and the abutment back wall 1.
[0022] The expansion joint 3 is internally provided with a finished U-shaped iron 2, the upper part of the finished U-shaped iron 2 is filled with neutral silica gel 9, the left finished profile steel 5 is welded on one side of the finished U-shaped iron 2, and the right finished profile steel 6 is welded on the other side of the finished U-shaped iron 2, the bridge deck pavement layer 4 covering the left finished profile steel 5 and the right finished profile steel 6 is laid on the top surface of the abutment back wall 1 and the main girder 2, the bolt 7 is threadedly connected to the left finished profile steel 5 and fixed to the top surface of the abutment back wall 1, and the right finished profile steel 6 is welded and fixed to the top surface of the main girder 2.
[0023] In the expansion structure of the utility model, the left finished profile steel 5 and the right finished profile steel 6 are arranged on both sides of the expansion joint 3, then the right finished profile steel 6 is fixed on the top surface of the main girder 2 by welding, the left finished profile steel 5 is fixed on the top surface of the abutment back wall 1 by the bolt 7, the finished U-shaped iron 2 is welded and fixed with the left finished profile steel 5 and the right finished profile steel 6, and the upper part of the finished U-shaped iron 2 is filled with the neutral silica gel 9, the upper part of the left finished profile steel 5 and the right finished profile steel 6 is paved with the bridge deck pavement layer 4, when the bridge expands and deforms, the finished U-shaped iron 2 and the neutral silica gel 9 deform together with the bridge, which neither affects the expansion and deformation of the bridge nor exposes the profile steel to affect the appearance.
[0024] In the embodiment, the expansion joint 3 is internally provided with the finished U-shaped iron 2, the upper part of the finished U-shaped iron 2 is filled with the neutral silica gel 9, and the left finished profile steel 5 and the right finished profile steel 6 are both arranged in the shape of "L".
[0025] In the expansion structure of the utility model, the left finished profile steel 5 and the right finished profile steel 6 are arranged on both sides of the expansion joint 3 by welding or bolt 7 fixing mode, since the upper part of the finished U-shaped iron 2 is filled with the neutral silica gel 9 and the upper part of the left finished profile steel 5 and the right finished profile steel 6 is paved with the bridge deck pavement layer 4, therefore, the problem that the profile steel expansion joint 3 is not beautiful is solved.
