Simple foot bridge expansion joint structure

Abstract

The invention relates to the technical field of pedestrian bridge expansion joints, and particularly discloses a simple pedestrian bridge expansion joint structure which comprises a caulking formed in a pavement layer, a structural joint located between two adjacent span main beams and a steel cover plate installed on a main beam structure and located above the structural joint. The caulking joint is located above one span of main beam structure, and the structural joint and the caulking joint are arranged in a staggered mode. The device can adapt to temperature change, so that the main beam structure and the pavement structure can realize telescopic deformation.

Description

technical field

[0001] The invention relates to the technical field of bridge expansion joints, and more specifically, relates to a simple footbridge expansion joint structure. Background technique

[0002] In the prior art, the processing methods for expansion joints specifically include the following methods:

[0003] 1. Set up U-shaped or V-shaped or W-shaped metal plates at structural joints, and fill the metal plates with fillers such as sealant or asphalt lint, which can adapt to the longitudinal deformation of the beam end through the deformation of U-shaped or V-shaped or W-shaped metal plates. This method can adapt to beam end deformation and various structural joint widths, but the strength of the filler is not enough. When the structural joints are wide, there will be a low-strength pavement layer of a certain width, which is easily damaged and affects practicability.

[0004] 2. The pavement layer is disconnected, the upper cover is made of steel plates, and the...

Embodiment Construction

[0023] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrated; it can be directly connected or indirectly connected through an intermediary, it can be the internal communication of two elements or the interaction relationship between two elements. The "first", "second" and similar words mentioned in this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Likewise, words like "a" or "one" do not denote a limitation in number, but indicate that there is at least one. In the implementation of this application, "and / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which may mean: A exists alone, A and B e...
