Description

Girder steel fixes a position hoist and mount otic placode fast

Technical Field

The utility model relates to a building technical field particularly, is exactly a hoist and mount otic placode is fixed a position fast to girder steel.

Background

The utility model discloses the technique provides a girder steel fixes a position hoist and mount otic placode fast and is used for the handling installation of girder steel.

The traditional steel beam hoisting method comprises the following steps: the hoisting lug plate for hoisting is welded on one fourth to one third of the length of the steel beam, the lug plate is connected with a steel hoisting rope to hoist the steel beam to a mounting position, the steel hoisting rope can be detached after a steel beam web bolt is mounted and positioned, and the hoisting machine moves to the other position to continue to be used, so that the conventional construction method has two problems: (1) the steel lifting rope lifted by the crane cannot be immediately detached, so that the crane occupies a long time, and the construction speed is directly influenced. (2) The steel lifting rope lifts the steel beam to be in shaking, so that the accurate adjustment and positioning of the mounting bolt are difficult, the misalignment of the butt welding seam of the beam flange is easily caused, and the mounting quality is directly influenced.

For solving the problem, the utility model provides a pair of girder steel fixes a position hoist and mount otic placode fast, directly shelve the support girder steel on the post bracket through the hoist and mount otic placode, can demolish the steel lifting rope immediately, let the loop wheel move to its operation, save greatly and occupy the loop wheel time, accelerate the construction speed, can carry out the micro-adjustment for the installation that makes girder steel web bolt, make the flange butt weld can not take place the wrong limit, the overhanging tip at the hoist and mount otic placode is cut into the hypotenuse (the horizontal chord length of cutting the hypotenuse should be than overhanging section length 20mm), dispose wedge steel gasket pad simultaneously and prop up below the hoist and mount otic placode, adjust the installation height difference of girder steel through removing the very easy micro-adjustment of steel wedge position, the girder steel stability by hoist and mount otic placode supporting can not rock, the bolt construction installation of being convenient for.

Disclosure of Invention

The utility model discloses the technique is that solve the quick accurate positioning problem of girder steel, and the invention content mainly is:

1. the conventional hoisting lug plate is shifted to the end part of the steel beam from the inside of the steel beam, the hoisting lug plate is properly lengthened to enable the conventional hoisting lug plate to extend 50mm out of the steel beam, and the steel beam can be directly supported on a bracket of the column by the extending section of the hoisting lug plate, so that a hoisting steel rope can be immediately detached, the operation of the crane is accelerated, and the construction speed is also accelerated.

2. The overhanging section of the hoisting lug plate is cut into the bevel edge, the steel wedge piece with the same inclination is configured to support and cushion below the hoisting lug plate, the steel wedge piece is moved to perform small height adjustment on the installed steel beam, the problem of misalignment of beam flange butt welding seams can be solved, and excellent installation quality is obtained.

Detailed Description

【1】 The utility model discloses a diagram is schematic, and the diagram is mainly for explaining technical meaning, all does not draw according to the drawing proportion, and the specification and size of various concrete component parts has been given to the description of carrying out concrete implementation here, nevertheless can replace with other similar specifications and sizes completely, should not regard as this as the limitation to the protection scope of the utility model constitutes.

【2】 The utility model discloses a to having the bracket or being provided with being connected of steel column and girder steel of outer crown plate, nevertheless also can be used to the girder and be connected with the similar of secondary beam, should not regard as with this the utility model discloses a protection range constitutes the restriction.

【3】 Example (b): in order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, technical features, and structural manners of the embodiments of the present invention concrete, the technical solutions in the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
