[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See also Figure 1-Figure 2 , Figure 5 The utility model provides the following technical solutions: a prefabricated composite floor placement and transportation rack, comprising a bearing base plate 1, a ball screw 9 is movably installed at the center of the top of the bearing base plate 1, one end of the ball screw 9 is fixedly connected to a hand wheel 8, both ends of the top of the ball screw 9 are movably connected to a bearing tray 4, both ends of the top of the bearing base plate 1 are movably installed with a slide rail 7, the top of the slide rail 7 is fixedly connected to the bearing tray 4, a plurality of pads 10 are fixedly installed on the top of the bearing tray 4, a plurality of frame columns 5 are fixedly connected to the top of the bearing tray 4, and a plurality of prefabricated composite floor slabs 6 are fixedly stacked between the relatively arranged frame columns 5.

[0025] Specifically, the operator first places the prefabricated floor slab into the device through a crane, and then controls the ball screw 9 through the hand wheel 8, and the thread directions at both ends of the ball screw 9 are opposite, so that the bearing pallets 4 at both ends of the top of the ball screw 9 are horizontally moved toward the center of the bearing base plate 1 under the support of the slide rail 7. When the bearing pallet 4 moves, it drives the frame column 5 to move, so that the prefabricated floor slabs of different sizes in the device can be quickly clamped and fixed, preventing the prefabricated floor slabs from sliding and falling during transportation, thereby reducing the danger of transporting the prefabricated floor slabs.

[0026] See also Figure 2 , Figure 4 A plurality of support rod holes 13 are provided inside the frame column 5, and a support rod 11 is movably sleeved inside the support rod holes 13.

[0027] Specifically, the operator can reasonably insert the support rod 11 into the support rod hole 13 according to the thickness of the prefabricated floor slab, and support each prefabricated floor slab individually, thereby increasing the number of prefabricated floor slabs stacked in the device and reducing the waste of space in the device.

[0028] See also Figure 1 , Figure 4 A plurality of legs 2 are fixedly installed at both ends of the bottom of the bearing base plate 1, and a plurality of lifting rings 3 are fixedly installed at both ends of the top of the bearing base plate 1.

[0029] Specifically, a forklift position is reserved between the two support plates of the whole device, and a lifting ring 3 is provided on the surface of the bearing bottom plate 1 to facilitate crane lifting, thereby overcoming the need for manpower and material resources to transport the device, reducing labor and improving work efficiency.

[0030] See also Figure 4 , several frame columns 5 have the same height, and the centers of the support rod holes 13 opened at the same height inside the frame columns 5 and the support rod holes 13 opened at the same height inside the oppositely arranged frame columns 5 are on the same straight line.

[0031] Specifically, the support rods 11 can stack the prefabricated floor slabs horizontally inside the device, and at the same time, a plurality of frame columns 5 can evenly distribute the weight of the prefabricated floor slabs, thereby ensuring the quality and service life of each floor slab.

[0032] See also Figure 5 The frame column 5 is made of I-steel, and the connection between the lower side wall of the frame column 5 and the bearing support plate 4 is set to be an inwardly concave rounded corner.

[0033] Specifically, I-beams have a low cost, and their cross-sectional properties are excellent and their bearing capacity is strong, which can reduce material consumption and transportation costs in the project, facilitate installation and disassembly, and improve construction efficiency. The connection between the lower side wall of the frame column 5 and the bearing tray 4 is set to an inwardly recessed rounded corner to enhance the stability of the device, allowing the frame column 5 and the bearing tray 4 to be docked and installed with each other.

[0034] See also Figure 5 A connecting beam 12 is fixedly connected between the frame columns 5 on the same side of the top of the supporting plate 4 , and the connecting beam 12 is fixedly installed in the middle of the frame column 5 .

[0035] Specifically, the operator installs the connecting beam 12 in the middle of the frame column 5 on the same side, so that the load-bearing system of the entire device is more stable, the solidity and firmness of the structure are ensured, and the force on the device is more uniform.

[0036] See also Figure 2 , Figure 5 The bearing base plate 1 and the bearing support plate 4 are made of high-strength steel, and the cushion block 10 is made of rubber.

[0037] Specifically, high-strength steel can withstand greater loads and pressures, and has good toughness and ductility, and can maintain stable performance in processes such as bending and stretching. Rubber pads are simple and quick to install, and are easy to maintain and replace. Rubber pads are durable and can withstand long-term pressure and wear.

[0038] The working principle and use process of the utility model: during the use of the utility model, the operator first puts the prefabricated floor slab into the device through the crane, and then controls the ball screw 9 through the hand wheel 8, and the thread directions at the two ends of the ball screw 9 are opposite, so that the bearing pallets 4 at the two ends of the top of the ball screw 9 are horizontally moved toward the center of the bearing bottom plate 1 under the support of the slide rail 7. While the bearing pallet 4 moves, it drives the frame column 5 to move, which can quickly clamp and fix the prefabricated floor slabs of different sizes in the device to prevent the prefabricated floor slabs from sliding and falling during transportation, reducing the danger in the transportation process of the prefabricated floor slabs and improving work efficiency. Then the operator can reasonably insert the support rod 11 into the support rod hole 13 according to the thickness of the prefabricated floor slab, and separately support the next prefabricated floor slab hoisted into the device, and distribute the weight of the floor slab to several frame columns 5, reducing the pressure on a single prefabricated floor slab, increasing the number of prefabricated floor slabs stacked by the device, reducing the waste of space in the device, and ensuring the quality and service life of each floor slab.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
