Embodiment 1

[0028] Such as Figure 1 to Figure 4 As shown, the beam used for high-altitude erection includes a beam body 1 in the shape of an I-shaped steel. The beam body 1 includes wing plates 11 on both sides and a web 12 in the middle. Both ends of the beam body 1 are fixed. a spreader;

[0029] Said hanger all comprises lug 6 and at least two splints, and said splints are provided with bolt holes, and also includes connecting bolts 5 for bolt connection between the splints, and the compressive stress provided by said splints through connecting bolts Clamped on the wing plate 11 of the beam body 1, the lug 6 is fixed on any one of the splints;

[0030] And the two spreaders are fixed on the same wing plate 11 of the beam body 1, the lugs 6 on each spreader are all protruding relative to the end of the beam body 1 where each spreader is located, and each lug 6 is provided with a hoisting Hole 7.

[0031] Concretely, two hangers respectively fixed on the different ends of the same wi...

Embodiment 2

[0035] Such as Figure 1 to Figure 4 As shown, the present embodiment is further limited on the basis of Embodiment 1: as a spreader implementation method that is convenient for installing the spreader on the corresponding wing plate 11, each spreader includes three splints: a first splint 2 and two second splints 3, two second splints 3 are respectively bolted to different ends of the first splint 2, and the length of the first splint 2 is longer than the width of the wing plate 11 used to be connected with the splint, the second The connecting points of the first splint 2 and the two second splints 3 are respectively located on different sides of the beam body 1;

[0036] The first splint 2 is in contact with the outer surface of the corresponding wing 11 , and the lugs 6 are all fixed on the outer surface of the first splint 2 . In this solution, before the beam body 1 is hoisted, the beam body 1 can be laid flat first, and the outer side of the wing plate 11 used to conne...

Embodiment 3

[0038] This embodiment further limits this case on the basis of the technical solution provided in embodiment 2, as Figure 1 to Figure 4 As shown, in order to optimize the stress at the connection point between the lug 6 and the first splint 2 and to facilitate the removal of the hook and the sling after the precise positioning of the beam is completed, the hoisting holes 7 on each lug 6 are connected to the end of the beam body 1 connect.

[0039] When hoisting the crossbeam, in order to prevent each spreader from sliding in the length direction of the crossbeam body 1, or to increase the difficulty of sliding, each second splint 3 is bolted to the first splint 2 through a connecting bolt 5, And the side surfaces of the two connecting bolts 5 are in contact with the side surfaces of the corresponding wing plates 11 . In this solution, when the splint on one side of the beam body 1 slides, the two connecting bolts 5 can constrain each other to achieve the above purpose.

Abstract

The invention discloses a cross beam for high-altitude erection. The cross beam comprises a cross beam body which is in an I-shaped steel shape. The cross beam body comprises wing plates on the two sides and a web in the middle, and lifting slings are fixed at the two ends of the cross beam body correspondingly; each lifting sling comprises a support lug and at least two clamp plates, bolt holes are formed in the clamp plates correspondingly, and the lifting slings further comprise connecting bolts used for bolted connection between every two clamp plates; the clamp plates are clamped on the wing plates of the cross beam body through pressure stress provided by the connecting bolts, the support lugs are fixed on any one of the clamp plates, and the two lifting slings are fixed on the same one wing plate of the cross beam body; and the support lugs on the lifting slings all protrude outwards relative to the end portions of the cross beam body where the lifting slings are located, and hoisting holes are formed in the support lugs correspondingly. According to the cross beam for high-altitude erection, the occupied time to a crane is short in the hoisting and installing process, the installing efficiency of the cross beam is high, and the construction safety can be strengthened.

Description

technical field [0001] The invention relates to the technical field of steel structure frames, in particular to a beam used for high-altitude erection. Background technique [0002] With the increase of large-scale buildings and the wide application of long-span beams, hoisting installation has become the main method of beam installation. Due to the heavy weight of most existing beams, after these beams are hoisted in place, they need to be docked with the main body of the building in the air before the constraints of the crane can be removed. Due to the flexibility of the suspension rope, especially when the extension length of the crane arm When it is longer, it is very difficult to complete the positioning of the beam in the air, so the docking of the beam in the air is actually extremely difficult. [0003] Due to the great difficulty of butt jointing of the beam, it is necessary to occupy the crane for a long time for the high-altitude hoisting operation of the beam. A...
