Description
Technical Field
[0001] The utility model relates to the technical field of concrete prefabricated components, in particular to a stacking and hoisting device for composite floor slabs. Background Art
[0002] A composite floor slab is an assembled integral floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. This kind of floor slab has the advantages of good integrity, large stiffness, good seismic performance, etc., and its upper and lower surfaces are flat, which is convenient for the decoration of the finishing layer. Therefore, the composite floor slab is particularly suitable for high-rise buildings and large-span buildings with high requirements for overall stiffness. After the precast floor slab is produced in the factory, it needs to be stacked, cured, handled, transported, etc., and the composite floor slab is stacked.
[0003] In the prior art, when placing the composite floor slab, the composite floor slabs are horizontally stacked and supported by sleepers between adjacent composite floor slabs. During the placement process, the lower composite floor slab is squeezed by the gravity of the upper composite floor slab, which affects the strength and quality of the lower composite floor slab. In severe cases, cracking and scrapping occur. In addition, when the composite floor slab is transferred and loaded onto the vehicle, it needs to be carried one by one, resulting in low construction efficiency and inevitable bumps, which affect the product quality. Therefore, a stacking and hoisting device for composite floor slabs is designed to solve the above problems. Summary of the Utility Model
[0004] Aiming at the defects in the prior art, the stacking and hoisting device for composite floor slabs provided by the utility model can avoid the situation that the bottom composite floor slab is squeezed by the upper composite floor slab, resulting in damage to the lower composite floor slab. During transportation, the device can be directly hoisted and loaded onto the vehicle through the lifting ring, which increases the working efficiency and avoids bumps of the composite floor slab, and has high practicability.
[0005] In order to solve the above technical problems, the utility model proposes the following technical solutions:
[0006] A stacking and hoisting device for composite floor slabs includes a bottom frame, an inverted concave frame, a diagonal brace, a lifting ring and a support rod. The inverted concave frames are fixedly arranged on the left and right sides of the upper surface of the bottom frame. The diagonal braces are fixedly arranged in the inverted concave frames. A plurality of embedding grooves are equidistantly arranged on the outer surface of the inverted concave frame, and the support rods are embedded in the embedding grooves.
[0007] Further, the embedding groove is arranged in an inclined shape with the horizontal height on the side far away from the opening being lower and the horizontal height on the side close to the opening being higher.
[0008] Further, the inclination angle of the embedding groove is 45-60° with respect to the angle of the outer surface of the inverted concave frame.
[0009] Further, the opening height of the embedding groove is not less than the diameter of the support rod, and the depth of the embedding groove is 3-4 times the diameter of the support rod.
[0010] Further, nuts are threadedly connected to both ends of the support rod.
[0011] Further, square timbers are placed on the left and right sides of the upper surfaces of two support rods at the same horizontal height. Further, a rotating plate is rotatably arranged on one side of the inner side of the embedding groove close to the opening through a hinge.
[0012] Further, the height of the rotating plate is equal to the opening width of the embedding groove, and the sum of the thickness of the rotating plate and the diameter of the support rod is not greater than the opening width of the embedding groove.
[0013] As can be seen from the above technical solutions, the beneficial effects of the present utility model are as follows:
[0014] 1. When placing the composite floor slab of the present utility model, first place the support rods in the embedding grooves at the bottoms of the left and right sides of the inverted concave-shaped frame, then place the square timbers on the left and right sides of the upper surfaces of the two support rods, and finally place the composite floor slab on the square timbers. Then, according to the thickness of the composite floor slab, place the support rods in the embedding grooves at the same horizontal height above, then place the square timbers on the left and right sides of the upper surfaces of the two support rods, and finally place the composite floor slab on the square timbers. Repeat the above operations until the composite floor slabs fill the bracket. The operation is simple and convenient. Each composite floor slab is supported by the support rods and the square timbers, achieving the effect of placing the composite floor slabs in layers, avoiding the situation that the bottom composite floor slab is squeezed by the upper composite floor slab, resulting in damage to the lower composite floor slab. And during transportation, the device can be directly hoisted and loaded onto the vehicle through the lifting rings, increasing the work efficiency, avoiding the collision of the composite floor slabs, and can also be applicable to the hoisting of composite floor slabs with different thicknesses, with good adaptability.
[0015] 2. The present utility model is provided with a rotating plate. When the support rod is placed in the embedding groove, the rotating plate rotates towards the inner side of the embedding groove, so that the rotating plate adheres to the upper surface of the embedding groove. The rotating plate does not affect the placement of the support rod in the embedding groove. After the support rod is placed in the embedding groove, the rotating plate is in a vertical state under the action of gravity. Since the height of the rotating plate is equal to the opening width of the embedding groove, the bottom of the rotating plate adheres to the bottom surface of the embedding groove, and the rotating plate cannot rotate towards the outer side of the embedding groove. The rotating plate blocks the support rod, preventing the support rod from falling out of the embedding groove due to vibration during transportation, and preventing the composite floor slab on the support rod from being damaged.

[0024] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, and therefore are only examples and cannot be used to limit the protection scope of the present utility model.
[0025] Refer to Figures 1-5 : A device for storing and hoisting laminated floors, comprising a bottom frame 1, an inverted concave frame 2, a diagonal brace 3, a lifting ring 4 and a support rod 5. Inverted concave frames 2 are fixedly arranged on both the left and right sides of the upper surface of the bottom frame 1. Diagonal braces 3 are fixedly arranged inside the inverted concave frames 2. A plurality of embedding grooves 201 are equidistantly formed on the outer surface of the inverted concave frames 2, and support rods 5 are embedded in the embedding grooves 201.
[0026] During actual use, when placing the composite floor slab, first place the support rods 5 in the embedding grooves 201 at the bottoms of the left and right sides of the concave-shaped frame 2, then place the square timbers on the left and right sides of the upper surfaces of the two support rods 5, and finally place the composite floor slab on the square timbers. Then, according to the thickness of the composite floor slab, place the support rods 5 in the embedding grooves 201 at the same horizontal height above, place the square timbers on the left and right sides of the upper surfaces of the two support rods 5, and finally place the composite floor slab on the square timbers. Repeat the above operations until the support frame is filled with the composite floor slabs. The operation is simple and convenient. Each composite floor slab is supported by the support rods 5 and the square timbers, achieving the effect of layered placement of the composite floor slabs, avoiding the situation where the bottom composite floor slab is squeezed by the upper composite floor slab and the lower composite floor slab is damaged. Moreover, during transportation, the device can be directly hoisted onto the vehicle through the lifting rings 4, increasing the work efficiency, avoiding collisions of the composite floor slabs, and can also be used to hoist composite floor slabs with different thicknesses, with good adaptability.
[0027] In this embodiment, the embedding groove 201 is arranged in an inclined shape with a lower horizontal height on the side far from the opening and a higher horizontal height on the side close to the opening, ensuring that the support rod 5 will not come out when it is in the embedding groove 201.
[0028] In this embodiment, the inclination angle of the embedding groove 201 and the angle of the outer surface of the concave-shaped frame 2 are 45 - 60°. The large inclination angle further prevents the support rod 5 from coming out of the embedding groove 201.
[0029] In this embodiment, the opening height of the embedding groove 201 is not less than the diameter of the support rod 5, and the depth of the embedding groove 201 is 3 - 4 times the diameter of the support rod 5. The large depth prevents the support rod 5 from coming out of the embedding groove 201.
[0030] In this embodiment, nuts 501 are threadedly connected to both ends of the support rod 5. By tightening the nuts 501, the lateral movement of the support rod 5 can be prevented, ensuring the stability of the support rod 5 in the embedding groove 201.
[0031] In this embodiment, square timbers are placed on the left and right sides of the upper surfaces of the two support rods 5 at the same horizontal height, and the composite floor slab is placed on the square timbers to prevent the hard contact between the support rod 5 and the composite floor slab and avoid the occurrence of damage to the composite floor slab during transportation.
[0032] In this embodiment, a rotating plate 202 is rotatably arranged on the inner side of the embedding groove 201 close to the opening through a hinge.
[0033] In this embodiment, the height of the rotating plate 202 is equal to the opening width of the embedding groove 201, so that the rotating plate 202 can only rotate into the interior of the embedding groove 201. Moreover, the sum of the thickness of the rotating plate 202 and the diameter of the support rod 5 is not greater than the opening width of the embedding groove 201, which facilitates the placement of the support rod 5 into and removal from the embedding groove 201 when the rotating plate 202 is attached to the upper surface of the embedding groove 201.
[0034] By providing the rotating plate 202, when the support rod 5 is placed into the embedding groove 201, the rotating plate 202 rotates towards the inner side of the embedding groove 201, causing the rotating plate 202 to adhere to the upper surface of the embedding groove 201. The rotating plate 202 does not interfere with the placement of the support rod 5 into the embedding groove 201. After the support rod 5 is placed into the embedding groove 201, the rotating plate 202 is in a vertical state under the action of gravity. Since the height of the rotating plate 202 is equal to the opening width of the embedding groove 201, the bottom of the rotating plate 202 adheres to the bottom surface of the embedding groove 201, and the rotating plate 202 cannot rotate towards the outer side of the embedding groove 201. The rotating plate 202 blocks the support rod 5, preventing the support rod 5 from falling out of the embedding groove 201 due to vibration during transportation, and preventing damage to the laminated floor slab on the support rod 5.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention 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 described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
