Abstract
The utility model provides an opening U-shaped concrete beam hoisting device, which comprises pre-buried bolts, a steel beam and lifting lugs, wherein the pre-buried bolts are pre-buried at the upper flange position of the opening U-shaped concrete beam; the steel cross beams are transversely anchored at the flange positions on the open concrete beam through embedded bolts, and at least two steel cross beams are arranged on each hoisting section; the lifting lugs are welded on the steel cross beams, and at least two lifting lugs are arranged on each steel cross beam to be used as a sling lifting point. The utility model provides an use roof beam body perforated bolt to make the roof beam body cross-section weaken impaired in the hoist and mount case in the past to and because the concrete member dead weight is great, the horizontal radial force that the hoist cable brought makes U-shaped beam web off-plate warp too big and lead to the impaired problem of U type beam web root fracture, the device can realize the dismantlement after quick installation and hoist and mount simultaneously.
Description
Technical Field
The utility model relates to a civil engineering field especially relates to an opening U type concrete beam hoist device.
Background
In civil engineering construction, the hoisting of the open U-shaped concrete beam is difficult. Due to the fact that the self weight of the concrete component is large, the out-of-plane deformation of the U-shaped beam web is large due to horizontal radial force brought by the sling, and therefore the root of the U-shaped beam web is cracked and damaged. In the existing hoisting cases, beam body perforated bolts are mostly used, so that the beam body section is weakened and damaged.
SUMMERY OF THE UTILITY MODEL
It is an object of the present invention to solve at least the above problems and to provide at least the advantages which will be described later.
In order to achieve the above and other objects, the present invention adopts the following technical solutions:
an open U-shaped concrete beam hoisting device comprises pre-buried bolts, steel cross beams and lifting lugs;
the embedded bolts are embedded in the upper flange positions of the open U-shaped concrete beams in a pre-embedding mode, the steel cross beams are transversely anchored in the upper flange positions of the open U-shaped concrete beams through the embedded bolts, and the lifting lugs are arranged on the top surfaces of the steel cross beams and used as sling lifting points.
The embedded bolts need to meet the anchoring length specified by the specification in the beam body, and the types and the number of the bolts can be determined according to stress calculation.
The utility model discloses a further technique:
preferably, the embedded bolt is a U-shaped bolt.
Preferably, the bolt holes are reserved in the positions, corresponding to the embedded bolts of the beam body, of the steel cross beams, at least two steel cross beams are arranged on each hoisting section, and the arrangement positions are determined according to the stress of the open U-shaped concrete beam in the hoisting stage.
Preferably, the lifting lugs are welded on the top surfaces of the steel cross beams, and at least two lifting lugs are arranged on each steel cross beam to be used as sling lifting points.
The utility model discloses there is following beneficial effect at least:
the steel beam is anchored on the upper flange of the U-shaped concrete beam, so that the opening U-shaped concrete beam forms transverse rigid connection at a lifting point, the out-of-plane deformation of a web plate of the U-shaped concrete beam is restrained, and the problem that the web plate is too large in out-of-plane deformation to crack and damage the web plate root due to horizontal radial force brought by slings in the lifting process of the opening U-shaped concrete beam is solved.

Example (b):
the utility model provides an opening U type concrete beam hoist device, includes buried bolt 1 in advance, steel crossbeam 2, lug 3 and opening U type concrete beam 4.
In the implementation, the embedded bolts 1 are embedded in the upper flange positions of the U-shaped concrete beam 4, the embedded bolts 1 need to meet the anchoring length specified by the specification in the beam body, and the types and the number of the bolts can be determined according to stress calculation.
The embedded bolts are embedded in the beam body, and the outer leakage bolt rods are cut off after the hoisting is finished, so that the problem of weakening the cross section of the U-shaped concrete beam is solved.
The steel beam 2 is transversely anchored at the upper flange position of the open U-shaped concrete beam 4 through the embedded bolt 1. The open U-shaped concrete beam 4 forms a transverse rigid connection through the steel cross beam 2 at the lifting point position. Every hoist and mount festival section should set up and be no less than twice steel crossbeam 2, and the position of setting is confirmed according to the atress of hoist and mount stage opening U-shaped concrete beam 4.
The steel beam is anchored on the upper flange of the open U-shaped concrete beam through the bolt, so that the steel beam can be quickly installed and disassembled after being hoisted.
The lifting lugs 3 are welded on the steel cross beams 2, and at least two lifting lugs 3 are arranged on each steel cross beam 2 to be used as sling lifting points. The steel beam 2 is provided with vertical stiffening ribs for stiffening according to stress requirements at the position of the lifting lug 3.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features.
