Embodiment 1

[0033] Combine below Figure 1 to Figure 12 , detailing the structural composition of the boom tower crane of the present invention without overturning beam resting corbels.

[0034] Please refer to Figure 1 to Figure 12 , a movable arm tower crane without overturning beams for shelving corbels, including a backboard 305 and a shelving steel tongue 310, the inner side of the backboard 305 is embedded in the pre-embedded area 202 of the concrete wall 02, the outer side of the backboard 305 is flush with the wall 201, and the backboard 305 is flush with the wall surface 201. Horizontal stiffeners 307 and vertical stiffeners 306 are fixed on the outer side of the plate 305, and the backplane 305 and the anchoring steel bar 301 are connected by a tapered sleeve 302. And fixed by the steel gasket 303 and fastening bolt 304 on the outside of the hole, one end of the smaller section of the tapered sleeve 302 is located on the inner side of the back plate 305, the anchoring steel ba...

Embodiment 2

[0046] Please continue to refer Figure 1 to Figure 12 , the present embodiment also provides a method for using a boom tower crane to leave a corbel without turning over a beam, and the method includes the following steps:

[0047] Step (1), when the tower crane climbs, the hoisting beam 01 lifts the first hoisting beam 01 by means of a winch placed on the top of the standard section;

[0048] Step (2), when the lifting beam 01 is lifted to the shelving corbel 03, and contacts with the shelving steel tongue 310 of the shelving corbel 03;

[0049] Step (3), continue to lift the lifting beam 01, at this time, the lifting beam 01 pushes the shelving steel tongue 310 to rotate, leaving space for the lifting beam 01 to continue to lift;

[0050] Step (4), after the lifting beam 01 continues to lift over the shelving steel tongue 310, the shelving steel tongue 310 is reset under the action of gravity;

[0051] Step (5), playback the lifting beam 01, put the lifting beam 01 on the...

Abstract

The invention provides an overturning-free beam shelving bracket of a movable arm tower crane and a mounting method, belongs to the technical field of building construction, and aims to solve the problems of overturning of a lifting beam of the movable arm tower crane and recycling of shelving bracket embedded parts. The overturning-free beam shelving bracket comprises a back plate and a shelving steel tongue, the back plate is embedded in an embedded area of a concrete wall, horizontal and vertical stiffening ribs are fixed on the outer side of the back plate, conical sleeves are used for connecting the back plate and anchoring steel bars, the anchoring steel bars are in threaded connection with the conical sleeves, and a pin shaft penetrates through a through hole of a triangular section of the shelving steel tongue and pin shaft holes of the vertical stiffening ribs to be fixed; and the three faces of the triangular shelving steel tongue are composed of a horizontal shelving face, a vertical face and an inclined face in sequence, and an arc-shaped bearing steel rib is arranged at the joint of the vertical face and the horizontal shelving face. When the tower crane lifts, the end portion of the lifting beam abuts against the triangular shelving steel tongue to drive the triangular shelving steel tongue to rotate, a space for the lifting beam to ascend is provided till the lifting beam crosses the shelving steel tongue, and after the shelving steel tongue is reset from eccentricity under the self-weight condition, the lifting beam also falls down and is shelved on the shelving steel tongue.

Description

technical field [0001] The invention relates to the technical field of building construction, and in particular to an installation method of a boom-tower crane without overturning beam shelving corbels and an installation method. Background technique [0002] At present, in civil construction, the climbing of heavy-duty tower cranes (such as boom tower cranes, etc.) is generally realized by turning over the lifting beam. Specifically, the lifting beam at the bottom of the tower crane is removed after the tower crane climbs and turned to the top for the next climb. Secondly, supporting the climbing beam of the tower crane is generally realized by making a concrete back plate. The back plate is made of a rectangular steel plate and welded with anchor bars. It is embedded in concrete components such as walls or structural beams before concrete pouring. When in use, the corbels are welded on the steel plate. This traditional method has the following disadvantages: 1. Waste of m...
