Description

Technical Field

[0001] The utility model relates to the technical field of assembled building equipment, in particular to a foldable and conveniently stored aluminum alloy hoisting and storage rack for prefabricated floor slabs. Background Art

[0002] Prefabricated floor panels are one of the important components of prefabricated buildings. Prefabricated floor panels are usually made in factories and then transported to the site for installation. In order to meet the on-site installation requirements of the project, the factory needs to prefabricate a large number of prefabricated floor panels, and at the same time, sufficient space is needed to store them. In order to save space, prefabricated floor panels usually require storage devices for support and stacking, and the hanger is a storage device that is convenient for both storage and lifting. When the prefabricated floor panels need to be hoisted on and off the vehicle, the hanger also becomes a carrier, so the user has higher requirements for its convenience in use, storage, transportation, turnover, etc. At present, the common hoisting racks on the market are fixed-volume racks, which are not convenient for turnover from the factory to the construction site, and cannot be folded and stored after use, which seems to take up more space. As in the prior art, the patent with publication number CN213622875A discloses a composite plate hoisting rack, and its structure is like this, which is difficult to meet the needs. Therefore, it is the purpose of the research and development of this designer to design a hanger that can be folded and convenient for storage and transportation. Utility Model Content

[0003] The utility model aims to provide a foldable and easy-to-store aluminum alloy hoisting and storage rack for prefabricated floor slabs in view of the above-mentioned problems and shortcomings.

[0004] The technical solution adopted by the utility model is: a foldable and easy-to-store aluminum alloy hoisting and storage rack for prefabricated floor slabs, comprising a hanger body and a lifting lug, the hanger body comprising a left hanger body, a right hanger body and a hinge and an unfolding and fixing device connecting the left hanger body and the right hanger body; the left hanger body and the right hanger body are both made of aluminum alloy profiles and are connected by welding to form a frame body surrounded by two transverse main beams and two longitudinal main beams, an inner transverse secondary beam and an inner longitudinal secondary beam arranged in the frame body, and a hanger reinforcement beam connecting adjacent transverse main beams and longitudinal main beams.

[0005] As a scheme, the unfolding and fixing device includes at least two groups of left fixed ribs and right fixed ribs respectively welded on the connecting surfaces of the left hanger body and the right hanger body, and the left fixed ribs and the right fixed ribs are provided with fixing holes which are co-axially located, and connecting round rods are passed through the fixing holes.

[0006] Furthermore, the left fixed ribs and the right fixed ribs are provided in three groups, each group has one left fixed rib, and each group has two right fixed ribs arranged in parallel, and a gap is left between the two right fixed ribs in each group for the left fixed rib to extend into, and when the left hanger body and the right hanger body are unfolded, the left fixed rib extends into the gap between the two right fixed ribs, and then the connecting round rod is passed through the fixing holes provided on the left fixed ribs and the right fixed ribs to lock the lower connection of the left hanger body and the right hanger body, thereby improving the overall compressive strength of the connected hanger body. When it is necessary to fold, just pull out the connecting round rod, and then use the hinge to fold the left hanger body and the right hanger body upwards.

[0007] As a scheme, the unfolding and fixing device includes at least two groups of fixing through holes and fixing bolts respectively arranged on the connecting surfaces of the left hanger body and the right hanger body. There are four groups of fixing through holes and fixing bolts. The transverse main beam, the longitudinal main beam, the inner transverse secondary beam, the inner longitudinal secondary beam and the hanger reinforcement beam are made of aluminum alloy I-beams, and the fixing through holes are opened on the middle rib plate of the longitudinal main beam, and reinforcing rods are welded on the outer rounded corners of the middle rib plate and the bottom plate. When the left hanger body and the right hanger body are unfolded, the fixing bolts are inserted into the fixing through holes and then the lower parts of the left hanger body and the right hanger body are locked by nuts, thereby improving the overall compressive strength of the connected hanger body. When it is necessary to fold, just loosen and remove the fixing bolts, and then use the hinges to fold the left hanger body and the right hanger body upwards.

[0008] As a solution, the transverse main beam, longitudinal main beam, inner transverse secondary beam, inner longitudinal secondary beam and hanger reinforcement beam are made of aluminum alloy I-beam.

[0009] Furthermore, the upper working surfaces of the left hanger body and the right hanger body are fully covered with rubber.

[0010] Beneficial technical effects of the utility model:

[0011] 1. The foldable connection structure can be folded to make its area smaller, reducing the storage and storage space, and also facilitating turnover;

[0012] 2. Compared with the existing channel steel hoisting and storage racks, the aluminum alloy hoisting and storage racks are light in weight and can be easily processed into the required specifications and models through sawing, drilling, punching, folding and other processing techniques, and are easy to manufacture;

[0013] 3. Aluminum alloy materials have a high recycling rate and produce very little waste, which complies with the national regulations on energy conservation, environmental protection, low carbon and emission reduction for construction projects. BRIEF DESCRIPTION OF THE DRAWINGS
