Description

Technical Field

[0001] The present application relates to the technical field of prefabricated beam hoisting, and in particular to a prefabricated beam hoisting protective structure. Background Art

[0002] Precast beams are factory-fabricated and then transported to the construction site for installation and fixation according to the design requirements. During transportation, these beams require gantry cranes. Conventional cranes typically use wire ropes to lift these beams. However, during this process, the wire ropes directly contact the corners of the beams, causing wear and tear at the points where they meet the ropes. This damages the beams, compromising their integrity and severely hindering construction. Utility Model Content

[0003] Based on this, it is necessary to provide a prefabricated beam hoisting protection structure to overcome the defects in the above-mentioned background technology.

[0029] Example

[0030] This embodiment provides a prefabricated beam hoisting protection structure, comprising a plurality of groups of protection components arranged in opposite directions along the axial direction of the prefabricated beam, each group of protection components is independently connected to a steel wire rope, and the protection components each include a skeleton 1, and the plurality of skeletons 1 are arranged around the prefabricated beam and are all located in the same vertical plane, such as Figure 1 As shown, the frame 1 has an arcuate outer surface and an arc-shaped groove 2 along its axial direction for connecting with the steel wire rope. Its inner side is L-shaped, used to connect with the upper and lower corners of the precast beam. By adding the frame 1 between the precast beam and the steel wire rope, direct contact between the two is avoided, reducing damage to the steel wire rope and the corners of the precast beam during lifting.

[0031] like Figure 2 and Figure 3 As shown, the skeleton 1 includes a curved panel 11 and an L-shaped panel 12. The radius of the curved panel 11 is greater than or equal to the minimum bending radius of the wire rope, and the groove 2 is located on the outside of the curved panel 11; a pair of L-shaped panels 12 that are cross-connected to each other are fixed to the inner side of the curved panel 11, and the angle between the pair of L-shaped panels 12 is the same as the curvature of the corner of the precast beam that the skeleton 1 contacts, so as to better fit at the corner of the precast beam.

[0032] In this embodiment, a first pad 3 is provided at the connection between the pair of L-shaped plates 12 and the prefabricated beam. The first pad 3 is made of flexible material. This structure can reduce the damage to the prefabricated beam caused by the sliding of the skeleton 1 during the lifting process.

[0033] In this embodiment, the bottom of the groove 2 is contracted inwardly so that the wire rope can be stuck inside the groove 2 to reduce its sliding. A second pad 4 bonded to the bottom of the groove 2 can also be added to reduce friction between the wire rope and the curved panel 11.

[0034] In this embodiment, the groove 2 is used to limit the wire rope to prevent it from sliding left and right. In order to prevent the wire rope from falling out of the groove 2, through holes 5 can be provided on both sides of the groove 2. A screw assembly 6 detachably connected to the through hole 5 is inserted into the through hole 5 to limit the wire rope to prevent it from falling out of the groove 2.

[0035] In this embodiment, a threaded hole 13 is provided on one side of the L-shaped plate 12 close to the adjacent frame 1, and the adjacent frames 1 in the same protective component can be connected to each other through a connector passing through the threaded hole 13, so as to ensure that the frames 1 in the same protective component are located in the same vertical plane.

[0036] The utility model prevents the steel wire rope from directly contacting the precast beam through multiple groups of protective components arranged around different cross sections of the precast beam. The inner and outer sides of the frame 1 are designed to fit the precast beam and the steel wire rope respectively, providing protection for the precast beam and the steel wire rope, avoiding direct contact between the steel wire rope and the corners of the precast beam, and effectively preventing the concrete at the corners of the precast beam from being damaged during hoisting.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
