DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0023] like Figures 1 to 4 As shown, a folding shelf for construction includes a connecting shelf 1, a sub-shelf 2 and a foot 3, wherein corresponding pin shafts 11 are fixedly disposed at the four end corners of the connecting shelf 1.

[0024] Furthermore, the sub-shelf 2 is provided with a first through hole 21 and a second through hole 22 for adapting the pin shaft and a receiving cavity 6 for accommodating the foot 3, and the sub-shelf 2 is provided with at least two, which are respectively placed at the left and right ends of the connecting shelf 1, wherein the receiving cavity 6 is a symmetrical structure and is arranged in the sub-shelf 2.

[0025] Furthermore, the foot 3 is provided with a third through hole 31 adapted to the pin shaft and a first limiting hole 32 adapted to the limiting screw 7 .

[0026] In this embodiment, the pins 11 extending from the four end corners of the connecting shelf 1 are fixedly connected by welding, wherein any one of the pins 11 is provided with a matching nut.

[0027] Furthermore, the accommodating cavity 6 in the sub-shelf 2 includes a longitudinal placement space 61 and a transverse placement space 62, wherein there is a height difference between the longitudinal placement space 61 and the transverse placement space 62, and the foot 3 is placed in the longitudinal placement space 61. The height difference can prevent the foot 3 from loosening before any pin shaft is connected.

[0028] Furthermore, when the foot 3 is placed in the longitudinal placement space 61 and is in an unfolded state, the third through hole 31 thereof is aligned with the center points of the first through hole 21 and the second through hole 22 .

[0029] The lateral placement space 62 extends to the left or right along the vertical direction of the foot.

[0030] In this embodiment, the connecting shelf 1 is a fixed component. The foot 3 is first placed in the accommodating cavity 6 provided in the sub-shelf 2. The sub-shelf 2 is connected to the pin shaft 11 through the first through hole 21, the second through hole 22 and the third through hole 31, and is connected at least at two places. Repeat this step to connect the second sub-shelf 2.

[0031] Furthermore, the nut matched with the pin shaft 11 is rotated and fixed, so that the two auxiliary shelves 2 and the connecting shelf 1 are fastened together to form the main body of the prefabricated component stacking shelf.

[0032] Furthermore, through this cooperation, the leg 3 can be rotated, and when the leg 3 is completely folded, it is placed in the lateral placement space 62 .

[0033] In this embodiment, in order to carry out aerial operations on the prefabricated component stacking shelves, tower crane plates 4 are provided on both sides of the outer wall of the auxiliary shelf 2, and there are at least two of them. The tower crane plates 4 are also provided with tower crane holes 41, and each tower crane plate 4 is provided with at least two tower crane holes 41.

[0034] The tower crane plate 4 is also provided with a fourth limiting hole 42 which can be adapted to the limiting screw 7 .

[0035] Further, to prevent the standing foot 3 placed in the accommodation cavity 6 from rotating during the use of the precast component stacking rack, the standing foot 3 can be fastened by connecting the fourth limiting hole 42, the second limiting hole 63, the third limiting hole 12 and the first limiting hole 32 through the limiting screw 7, and the standing foot 3 cannot rotate in this state.

[0036] In this embodiment, to provide the precast component stacking rack with good support and stability, a support plate 5 is further provided at the bottom of the secondary rack 2 and is arranged below the standing foot 4.

[0037] Further, both the tower crane plate 4 and the support plate 5 are selected with metals having high strength and durability as raw materials, and can withstand greater pressure or gravity.

[0038] In summary, by splitting the precast component stacking rack into three parts, the present utility model reduces the floor area occupied when the precast component stacking rack is idle, simplifies the structure of the precast component stacking rack, and reduces the transportation cost during the transportation of the precast component stacking rack.

[0039] The above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
