Abstract

A kind of sections pier shaft docking operation workbench, it is characterized in that described workbench comprises the workbench truss main body arranged around sections pier shaft periphery, the inner side distribution of workbench truss main body is arranged sling point and is arranged by hoist cable hanging, described workbench truss main body is arranged with spacing diagonal brace mechanism, and between the side of this spacing diagonal brace mechanism and sections pier shaft, spacing laminating is arranged.This sections pier shaft docking operation workbench installation is convenient, can need conveniently to carry out height according to construction to regulate, this workbench can and sections pier shaft ring side between carry out stable spacing while it can solve external environment condition and space institute by lifting and limits the problem brought, meet the requirement of efficiently constructing and safety is high.

Description

A kind of sections pier shaft docking operation workbench
Technical field
The prefabricated subsection pier shaft that the utility model belongs to overhead road bridge carries out auxiliary equipment during docking operation, is specifically related to a kind of sections pier shaft docking operation workbench carrying out butt end surface construction when docking up and down sections pier shaft.
Background technology
Along with the development of bridge and overhead road bridge technology, marine or become the important engineering of bridge construction across the overhead road bridge construction in waters.Due to viaduct many employings Steel Continuous Box beam bridge, the supporter of non-navigation bridge mostly is prefabricate and install pier structure, can be divided into overall pier, cushion cap adds lower joint pier shaft, middle joint pier shaft and upper joint pier shaft Four types by classification.Because the overall weight of prefabricated pier shaft can reach more than 2000 ton, how to carry out effectively and safty hoisting and location and installation become the important technological problems needing solution, therefore can multi-segmental be divided into carry out pier shaft when carrying out prefabricated prefabricated, and then carry out on-the-spot docking construction.
The bottom pier shaft of segmented pier shaft and cushion cap in place after, when centering sections pier shaft or upper sections pier shaft carry out lifting docking operation, be in certain altitude due to this docking operation and be in lifting state due to upper segment pier shaft, the operation carrying out epoxy resin gluing, prestressed thick reinforcement connection and tensioning etc. in docking operation all needs outside to provide metastable platform to meet construction requirement.
Utility model content
It is convenient that the utility model provides a kind of installation, the sections pier shaft docking operation workbench conveniently carrying out highly adjustment can be needed according to construction, this workbench can and sections pier shaft ring side between carry out stable spacing while it can solve external environment condition and space institute by lifting and limits the problem brought, meet the requirement of efficiently constructing and safety is high.
The technical scheme that the utility model adopts is as follows:
A kind of sections pier shaft docking operation workbench, it is characterized in that described workbench comprises the workbench truss main body arranged around sections pier shaft periphery, the inner side distribution of workbench truss main body is arranged sling point and is arranged by hoist cable hanging, described workbench truss main body is arranged with spacing diagonal brace mechanism, and between the side of this spacing diagonal brace mechanism and sections pier shaft, spacing laminating is arranged.
Concretely, described workbench truss main body comprises the rectangular box that four splicings connect, and described sling point is the hanger that distribution is arranged on the workbench truss main body welding of the inner annular edge of its length direction.
In one embodiment, the outer ledge of described workbench truss main body is equipped with guardrail, and described guardrail is positioned at the relative dual-side of workbench truss main body.
In another embodiment, described spacing inclined support structure comprises the spacing angle steel that inner side two opposite edges along workbench truss main body extend downwards, and the oblique extension of outer ledge of described workbench truss main body also supports oblique steel with being fixedly connected with between spacing angle steel.
In one embodiment, the described inner side of workbench truss main body and the inner side of spacing inclined support structure are all equipped with yielding rubber, and the side of described yielding rubber laminating sections pier shaft is arranged.
In one embodiment, described workbench truss main body is the space truss of the two groups of steel flat layered structures be up and down welded by i iron and angle steel.
This sections pier shaft docking operation workbench adopts truss as its main body, the rectangular box around sections pier shaft structure that workbench truss main body can form for the welding of steel structure or bolt.This workbench truss main body can be four groups independently truss carry out annular and connect to form.Truss is the space truss that clad steel structure body is formed by connecting by angle steel and i iron.Space truss is as the supporting part of workbench.Its two relative sides and long side arrange the use region that railing forms operation construction.Whole workbench is that the bracket and hoist cable by being positioned at sections pier shaft top carries out lifting setting.Hoist cable is vertically arranged along the side of sections pier shaft, can also carry out the height change of this workbench by hoist cable and fix, the use in the lump of sections pier shaft and even upper sections pier construction in meeting while decreasing wobble effects.In addition, in order to keep the stability of workbench in work progress, this workbench have employed spacing inclined support structure, increases the face contact height of workbench and sections pier shaft side, and the mode by setting up yielding rubber alleviates and shakes and increase frictional force.
The beneficial effects of the utility model are, this sections pier shaft docking operation workbench installation is convenient, can need conveniently to carry out height according to construction to regulate, this workbench can and sections pier shaft ring side between carry out stable spacing while it can solve external environment condition and space institute by lifting and limits the problem brought, meet the requirement of efficiently constructing and safety is high.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the opposing party's bit architecture schematic diagram of the utility model embodiment.
Detailed description of the invention
As depicted in figs. 1 and 2, this sections pier shaft docking operation workbench has the workbench truss main body 10 arranged around sections pier shaft 20 periphery, workbench truss main body 10 comprises the rectangular box that four splicings connect, and is the space truss of the two groups of steel flat layered structures be up and down welded by i iron and angle steel.The inner side distribution of workbench truss main body is arranged sling point 12 and is hung by hoist cable 31 and arranges, and hanging basis is the bracket 30 at sections pier shaft top.Sling point 12 is the hanger that distribution is arranged on the workbench truss main body welding of the inner annular edge of its length direction.The outer ledge of workbench truss main body 10 is equipped with guardrail 11, and described guardrail is positioned at relative two long sides of workbench truss main body.Workbench truss main body is arranged with spacing diagonal brace mechanism 16, and between the side of this spacing diagonal brace mechanism 16 and sections pier shaft, spacing laminating is arranged.Spacing inclined support structure 16 comprises the spacing angle steel 13 that inner side two opposite edges along workbench truss main body extend downwards, and the oblique extension of outer ledge of described workbench truss main body also supports oblique steel 14 with being fixedly connected with between spacing angle steel.The inner side of workbench truss main body and the inner side of spacing inclined support structure are all equipped with yielding rubber 15, and the side of described yielding rubber laminating sections pier shaft is arranged.
