Embodiment 1

[0013] Such as figure 1 As shown, the installation structure of the step plate in the bridge construction project includes a support plate 2, a positioning plate 3 and a fixing mechanism, wherein the positioning plate 3 is vertically arranged vertically and its left end surface is close to the right end surface of the concrete bridge wall 1, and the support plate 2 It is horizontally arranged and its left end is connected to the right end surface of the positioning plate 3 . The fixing mechanism of the present embodiment comprises a positioning bolt 4, an inner positioning nut 5, an outer positioning nut 6, a rigid gasket 7 and an elastic backing plate 8, and the head of the positioning bolt 4 and the inner positioning nut 5 are all located on the concrete bridge. Inside the wall 1 , the other end of the screw rod of the positioning bolt 4 opposite to the head end passes through the internal positioning nut 5 and the positioning plate 3 in sequence and is arranged outside the ...

Embodiment 2

[0015] This embodiment makes the following further limitations on the basis of Embodiment 1: In this embodiment, the right end of the inner positioning nut 5 is flush with the right end surface of the concrete bridge wall 1 .

Embodiment 3

[0017] On the basis of Embodiment 1 or Embodiment 2, this embodiment makes the following further limitations: the positioning plate 3 of this embodiment is a rectangular plate, the number of fixing mechanisms is four groups, and the positioning bolts 4 of the four groups of fixing mechanisms pass through The positions of the positioning plate 3 are respectively close to the four right-angled corners of the positioning plate 3 .

Abstract

The invention discloses a mounting structure of a flier in a bridge construction project. The mounting structure of the flier in the bridge construction project comprises a supporting plate, a locating plate and a fixing mechanism, wherein the locating plate is vertically arranged in a longitudinal direction; the left end surface of the locating plate sticks to the right end surface of a concrete bridge wall; and the supporting plate is horizontally arranged in a transverse direction and the left end of the supporting plate is connected with the right end surface of the locating plate. The fixing mechanism comprises a locating bolt, an internal locating nut, an external locating nut, a rigid gasket and an elastic backing plate, wherein the other end, opposite to the connecting head end, of a screw rod of the locating bolt penetrates through the internal locating nut and the locating plate in sequence and is arranged outside the concrete bridge wall. The external locating nut, the rigid gasket and the elastic backing plate sleeve the screw rod, positioned outside the concrete bridge wall, of the locating bolt; the left and right end surfaces of the rigid gasket are respectively in contact with the right end surface of the locating plate and the left end surface of the elastic backing plate; and the right end surface of the elastic backing plate is in contact with the left end surface of the external locating nut. The invention is advantaged in that the integral structure of the mounting structure is simple and firm, the mounting structure is convenient to realize, the mounting structure is convenient to operate during mounting, the mounting structure is time-saving and labor-saving, and the mounting structure is convenient for erecting and constructing a halfpace for construction personnel to step.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a mounting structure for step plates in bridge construction engineering. Background technique [0002] In the construction process of expressways, high-speed railways and urban viaducts, bridge construction occupies a large proportion. In bridge construction, no matter what type of bridge, there are only two construction methods, one is prefabricated installation construction, and the other is cast-in-place construction. In the construction process of large bridges, whether it is prefabricated installation construction or cast-in-place construction, in order to facilitate the construction personnel to reach the construction site during construction, a supporting platform is required during the construction process. Nowadays, in the bridge construction process, in order to ensure the structure of the platform Strength, the process of setting up the ladder is cumbersome, time-co...
