Description

Technical Field

[0001] This utility model relates to the field of composite slab transportation technology, and in particular to a device for improving the full load rate of composite slab transportation. Background Technology

[0002] Composite slabs are a new type of prefabricated building component. They are constructed by prefabricating floor slabs in functional layers and then reliably stacking them together. During construction, the prefabricated base slab is installed first, followed by the pouring of the upper layer of concrete to form a unified structure. This process combines the advantages of prefabrication and cast-in-place construction, improving construction efficiency, shortening the construction period, and ensuring the structural integrity and seismic performance. Composite slabs offer advantages such as controllable quality, saving formwork, and reducing on-site wet work. They are widely used in prefabricated buildings and are a key technology driving the industrialization of construction, contributing to improved building quality and sustainability.

[0003] After precast composite slabs are cast in the factory, they need to be transported from the processing workshop to the construction site by transport vehicles. Under the current technology, the transportation of precast composite slabs mainly has the following problems: According to relevant specifications, the number of stacked layers of precast composite slabs should not exceed 6 layers. If the stacking is too high, it will cause damage to the structure of the precast composite slabs. Therefore, during the transportation of precast composite slabs, the stacking generally does not exceed 6 layers. As a result, the weight of the composite slabs transported by the transport vehicle is far less than the rated load capacity of the transport vehicle. The number of slabs transported in a single transport vehicle is small, and multiple batches of transport are required. The efficiency of the transport vehicles is low. Therefore, a device to improve the full load rate of composite slab transportation is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the limitation that the number of precast composite slabs stacked should not exceed 6 layers according to relevant specifications, as excessive stacking can damage the structure of the precast composite slabs. Therefore, during the transportation of precast composite slabs, the stacking is generally limited to no more than 6 layers, resulting in the weight of the composite slabs transported by the transport vehicle being far less than the rated load capacity of the transport vehicle, leading to a small number of slabs transported per trip, requiring multiple batches of transport, and resulting in low efficiency of the transport vehicle. The invention proposes a device to improve the full load rate of composite slab transportation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for improving the load-bearing capacity of composite slab transport includes a frame with multiple sets of multi-layer components. Each set of multi-layer components includes an I-shaped block and a lifting plate movably connected to the outside of the frame, and a first bolt rotatably connected to the outside of the frame. The I-shaped block drives the lifting plate to insert into the bottom layer of the frame, and the first bolt fixes the I-shaped block to the frame. The composite slab is placed on the multiple lifting plates, and then another I-shaped block and lifting plate are inserted, fixing the I-shaped block above the first fixing position. Finally, a sleeper is placed in the middle position of the composite slab and a second inserted lifting plate. The stacked panels are then placed on the second set of support plates, and this process is repeated multiple times to complete the stacking of multiple layers of stacked panels. The frame is equipped with a layering assembly, which includes multiple support plates and a second bolt that are movably connected to the upper part of the frame, as well as multiple square blocks that are fixedly connected to the upper part of the frame. The multiple support plates are stably placed on the frame by the square blocks, and the support plates are connected to the frame by the second bolts, so that the upper part of the frame is formed into a plane by the multiple support plates, dividing the frame into two parts. Stacked panels can be stacked again on the support plates above the frame.

[0007] The above technical solution further includes:

[0008] The outer side of the frame is provided with multiple first threaded grooves. The first threaded grooves are threadedly connected to the threaded rod. The end of the threaded rod away from the first threaded groove is fixedly connected to a limiting plate. The rotation of the threaded rod drives the threaded rod to move into the first threaded groove.

[0009] The frame has a second threaded groove on its side and an I-shaped groove on its side. The I-shaped block and the I-shaped groove are slidably connected. The uniform layering of the second threaded groove corresponds to the stacking of the composite plates.

[0010] The second thread groove consists of multiple sets arranged linearly and evenly. The opening size of the I-shaped groove is adapted to the size of the I-shaped block, and the cross-sections of both the I-shaped groove and the I-shaped block are I-shaped. The special shapes of the I-shaped groove and the I-shaped block enhance the mutual support force.

[0011] The side of the I-shaped block is provided with a fourth threaded groove. The first bolt is threadedly connected to both the second and fourth threaded grooves. The connection between the first bolt and the second and fourth threaded grooves fixes the I-shaped block in the I-shaped groove.

[0012] The I-shaped block is fixedly connected to the support plate on the side away from the first bolt. A rubber block is fixedly connected to the upper part of the support plate to increase the friction of the composite plate.

[0013] The support plate has a third threaded groove symmetrically formed on its outer side, and the square block has a fifth threaded groove formed on its outer side. The second bolt is threadedly connected to both the third and fifth threaded grooves. The support plate is then combined with the frame and the square block by the threaded connection between the second bolt and the third and fifth threaded grooves.

[0014] The side of the support plate is symmetrically provided with square grooves, and the square blocks are slidably connected to the square grooves. Multiple support plates are combined with the square blocks through the square grooves.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the I-shaped block and the lifting plate, which are movably connected to the outer side of the frame in the multi-layer component, and the first bolt that is rotatably connected, can flexibly adjust the position of the lifting plate and fix it. The I-shaped block and the lifting plate can be inserted multiple times as needed to achieve stable stacking of multi-layer composite plates. This breaks through the traditional limitation on the number of stacking layers, and the operation is relatively simple. It can effectively utilize the space of the transport vehicle, increase the number of composite plates transported in a single trip, improve the full load rate of the transport vehicle, reduce the number of transport batches, improve transport efficiency, and reduce transport costs.

[0017] In this invention, multiple support plates are movably connected to the upper part of the frame in the layered assembly. These plates are then stably placed with the help of fixedly connected square blocks and tightly connected with second bolts. This allows the upper part of the frame to form a flat plane, effectively dividing the frame into two parts. After stacking the composite plates below using the multi-layered assembly, they can be stacked again on the upper support plates. This fully utilizes the vertical space of the transport vehicle, further increasing the number of composite plates transported in a single trip and greatly improving the load factor of the transport vehicle.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, as Figures 1-4 As shown, this utility model proposes a device for improving the full load rate of transporting composite slabs. It includes a frame 1, on which multiple sets of multi-layer components are arranged. Each set of multi-layer components includes an I-shaped block 10 and a lifting plate 12 movably connected to the outside of the frame 1, and a first bolt 7 rotatably connected to the outside of the frame 1. The I-shaped block 10 drives the lifting plate 12 to insert into the bottom layer of the frame 1. The first bolt 7 fixes the I-shaped block 10 to the frame 1. The composite slab is placed on the multiple lifting plates 12, and then the I-shaped block 10 and the lifting plate 12 are inserted again, fixing the I-shaped block 10 above the first fixing position. Then, sleepers are placed in the middle position of the composite slab and the second... The inserted support plates 12 are aligned, and the stacked plates are placed on the second set of support plates 12. This process is repeated multiple times to complete the stacking of multiple stacked plates. The frame 1 is equipped with a layering assembly, which includes multiple support plates 6 and a second bolt 17 that are movably connected to the upper part of the frame 1, as well as multiple square blocks 15 that are fixedly connected to the upper part of the frame 1. The multiple support plates 6 are stably placed on the frame 1 through the square blocks 15. The support plates 6 are connected to the frame 1 through the second bolt 17, so that the upper part of the frame 1 is formed into a plane through the multiple support plates 6, dividing the frame 1 into two parts. Stacked plates can be stacked again on the support plates 6 above the frame 1.

[0025] Multiple first threaded grooves 4 are provided on the outer side of the frame 1. The first threaded grooves 4 are threadedly connected to the threaded rod 2. The end of the threaded rod 2 away from the first threaded groove 4 is fixedly connected to the limiting plate 3. The rotation of the threaded rod 2 drives the threaded rod 2 to move into the first threaded groove 4.

[0026] The side of the frame 1 is provided with a second threaded groove 5 and an I-shaped groove 9. The I-shaped block 10 is slidably connected to the I-shaped groove 9. The uniform layering of the second threaded groove 5 corresponds to the stacking of the composite plates.

[0027] The second threaded groove 5 consists of multiple sets arranged linearly and evenly. The opening size of the I-shaped groove 9 is adapted to the size of the I-shaped block 10, and the cross-sections of both the I-shaped groove 9 and the I-shaped block 10 are I-shaped. The special shapes of the I-shaped groove 9 and the I-shaped block 10 enhance the mutual support force.

[0028] The side of the I-shaped block 10 is provided with a fourth threaded groove 11. The first bolt 7 is threadedly connected to the second threaded groove 5 and the fourth threaded groove 11. The combination of the first bolt 7 with the second threaded groove 5 and the fourth threaded groove 11 fixes the I-shaped block 10 in the I-shaped groove 9.

[0029] The side of the I-shaped block 10 away from the first bolt 7 is fixedly connected to the lifting plate 12. A rubber block 13 is fixedly connected to the upper part of the lifting plate 12, and the rubber block 13 increases the friction of the composite plate.

[0030] In this embodiment, by placing the frame 1 on the carriage, the limiting disc 3 is rotated. The rotation of the limiting disc 3 causes the threaded rod 2 to move into the first threaded groove 4, bringing the limiting disc 3 closer to the side of the carriage. This fixes multiple limiting discs 3 to the side of the carriage, providing initial restriction and fixation for the frame 1. Then, a sleeper is placed in the middle of the frame 1, flush with the bottom horizontal plate. Next, the first composite plate is placed. At this point, the top of the frame 1 is open, and the support plate 6 is not placed on the frame 1, facilitating the placement of the composite plate. The lifting plate 12 is then grasped by hand, causing the lifting plate 12 to drive the I-shaped block 10 into the bottom layer of the frame 1. The I-shaped block 10 then drives the fourth threaded groove 11 to engage with the second threaded groove at the bottom. The grooves 5 are on a parallel line. The I-shaped block 10 is fixed in the I-shaped groove 9 by the combination of the first bolt 7 with the second threaded groove 5 and the fourth threaded groove 11. At this time, the sleeper is placed at the center of the first composite plate and is flush with the first placed support plate 12. The composite plate is placed on multiple support plates 12 again. Then the I-shaped block 10 and support plates 12 are inserted to fix the I-shaped block 10 above the first fixed position. Then the sleeper is placed in the middle of the composite plate and is flush with the second inserted support plate 12. The composite plate is placed on multiple support plates 12 again. This operation is repeated many times to complete the stacking of multiple composite plates, realizing the stacking of multiple composite plates, which is larger than the existing stacking range.

[0031] Example 2, as Figures 1-4 As shown, based on Embodiment 1, the outer side of the support plate 6 is symmetrically provided with a third threaded groove 8, and the outer side of the square block 15 is provided with a fifth threaded groove 16. The second bolt 17 is threadedly connected to both the third threaded groove 8 and the fifth threaded groove 16. By connecting the second bolt 17 to the third threaded groove 8 and the fifth threaded groove 16, the support plate 6 is combined with the frame 1 and the square block 15.

[0032] The side of the support plate 6 is symmetrically provided with square grooves 14, and the square block 15 is slidably connected to the square groove 14. Multiple support plates 6 are combined with the square block 15 through the square groove 14.

[0033] In this embodiment, as described in the previous step, when the stacked plates inside the frame 1 are stacked, multiple support plates 6 are combined with square blocks 15 through square slots 14, so that the support plates 6 are stably placed on the frame 1. The second bolt 17 is threadedly connected to the third threaded slot 8 and the fifth threaded slot 16, so that the support plates 6 are combined with the frame 1 and the square blocks 15. The upper part of the frame 1 is formed into a plane by multiple support plates 6, so that the frame 1 is divided into two parts. Stacked plates can be stacked again on the support plates 6 above the frame 1, thereby improving the stacking efficiency of the stacked plates and increasing the transportation effect.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
