The invention aims to provide a fixing structure and an installation method which can realize reliable connection between a connecting lug plate and a hoisting steel beam and hoist the connecting lug plate together with the steel beam.
Description
Technical Field
The invention relates to the technical field of steel structure installation engineering, in particular to a fixing structure and an installation method of a steel beam and a connecting lug plate.
Background
Along with the technical development in the engineering construction field, steel structure buildings are more and more applied to various building fields, and the main connection mode between steel structure members is welding and bolting.
In steel structure engineering, there are several kinds of connected modes such as welded connection, bolted weld connection in the girder steel connection mainly, and when adopting bolted connection or bolted weld to connect, the girder steel web generally adopts engaging lug board cooperation high strength bolt to connect. The connecting lug plates are changed in specification and size along with the size of the steel beam, when the steel beam is large, the connecting lug plates are generally large in self weight, high-altitude hoisting is needed to be carried out to the installation position for positioning and installation, the number of the lug plates is usually large, a hoisting device needs to be added independently in the hoisting installation, the hoisting efficiency is low, and the positioning time is long. The manual matching mechanical positioning safety coefficient is lower.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a fixing structure and a mounting method which can realize reliable connection between a connecting lug plate and a hoisting steel beam and can hoist the connecting lug plate together with the steel beam.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a fixing structure of a steel beam and a connecting lug plate comprises a hoisting steel beam, wherein positioning rings are vertically and symmetrically arranged on a web plate of the hoisting steel beam; and a fixing piece with a hook is inserted into the positioning ring, and the other end of the fixing piece is fixedly connected with a connecting lug plate together.
Furthermore, the positioning ring is rotatably connected with the fixing piece through threads.
Further, the positioning ring is composed of a nut, and the fixing piece is formed by bending a reinforcing steel bar head by 90 degrees.
The method for fixedly mounting the steel beam and the connecting lug plate comprises the following steps:
(1) vertically and symmetrically welding positioning rings at the web plate position of the hoisting steel beam, and inserting matched fixing pieces into the positioning rings;
(2) after the connecting ear plate is placed at the position to be installed, the connecting ear plate is welded and fixed with each fixing piece;
(3) before hoisting the steel beam, the connecting lug plates are rotated 180 degrees from the positions to be installed to the opposite sides, after the steel beam is hoisted in place, the connecting lug plates are rotated 180 degrees around the fixing rings in the reverse direction to the positions to be installed, and the steel beams are connected through the connecting lug plates.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, the connection lug plate and the hoisting steel beam can be hoisted simultaneously, so that a new hoisting device is avoided, before the steel beam is hoisted, the connection lug plate is positioned in a mirror image mode on the ground through the rotating fit between the fixing piece bent by 90 degrees and the positioning ring, and after the steel beam is hoisted, the connection lug plate is rotated to the simulated installation position, so that the hoisting and positioning safety risks can be reduced efficiently, conveniently and simultaneously. The fixing piece can be formed by bending the waste reinforcing steel bar head by 90 degrees, so that the use cost can be saved.
