Description

Technical Field

[0001] This utility model relates to the technical field of transportation devices for precast concrete components, and in particular to a transportation bracket device for an ultra-thin high-performance concrete base plate. Background Technology

[0002] Currently, with the vigorous development of prefabricated buildings, ultra-thin high-performance concrete slabs are popular due to their thinness (only 15-20mm of precast layer thickness), high concrete strength (C80 and above), and high standardization (1200mm width, with length determined by the actual dimensions of the building). These products are suitable for assembly line production, especially in public buildings. However, public building rooms often have large spans or depths, with some slabs measuring 5-6 meters in length. The transportation of these slabs requires consideration of economic efficiency, as a single transport rack can stack approximately 15 layers of slabs. Therefore, the traditional method of using scaffolding for transporting such thin, large, and brittle components presents the following problems:

[0003] 1. Insufficient rigidity and easy to crack: The bottom plate will bend and deform under the dynamic load of the transport vehicle, but micro-cracks will be generated due to excessive deformation. These micro-cracks will seriously affect its final load-bearing capacity and durability.

[0004] 2. Traditional grid-like frames are prone to unevenness during manufacturing, resulting in a high center and low sides. This makes the ultra-thin high-performance concrete base plate prone to cracking in the middle during storage or transportation.

[0005] 3. Improper support leads to stress concentration: Insufficient support points will cause the bottom plate to bear concentrated loads, which can easily cause punching damage or local crushing when bumpy.

[0006] 4. Difficult to secure, posing a safety hazard: The bottom transport bracket is not fixed to the transport vehicle, and there is a risk of the whole structure slipping during emergency braking.

[0007] 5. Low loading and unloading efficiency: When using the traditional method of transporting scaffolding, loading and on-site hoisting are mostly done on a single plate, which is inefficient. Utility Model Content

[0008] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a transport bracket device for ultra-thin high-performance concrete base plates. Its structure is simple and stable, which can effectively protect the ultra-thin high-performance concrete base plates from damage during transportation. It is also highly versatile and easy to operate.

[0009] To achieve the above objectives, this utility model provides a transport bracket device for ultra-thin high-performance concrete slabs, comprising: a main support frame for supporting the concrete slab stacks formed by stacking high-performance concrete slabs; a multi-point elastic support system including multiple support columns arranged on the upper surface of the main support frame and a flexible support pad layer laid on the top of all support columns; a limiting system connected to the main support frame to form a three-dimensional binding space for fixing the concrete slab stacks; and a fixing system located at the bottom of the main support frame for fixed connection with a transport vehicle.

[0010] Preferably, the limiting system consists of multiple flexible strips arranged perpendicular to the length of the high-performance concrete base plate along a ring of stacked concrete base plates and multiple flexible strips arranged parallel to the length of the high-performance concrete base plate along a ring of stacked concrete base plates.

[0011] Furthermore, flexible pads are provided at the contact points between the flexible strip and the high-performance concrete base plate.

[0012] Furthermore, the main support frame is a three-dimensional grid frame welded together from several parallel main beams and several secondary beams connecting the main beams.

[0013] Preferably, both the main beam and the secondary beam are made of rectangular steel pipes, the center-to-center distance between two adjacent main beams is 200-250mm, the center-to-center distance between two adjacent secondary beams is 600-800mm, and the main beam is located above the secondary beam.

[0014] Furthermore, the fixing system includes angle steels located at the bottom of the four corners of the main support frame. The angle steels are connected to the secondary beams via tie rods. The secondary beams have elliptical holes through which the tie rods pass. The angle steels are fixed to the transport vehicle's platform by spot welding.

[0015] Preferably, the supporting column is made of rectangular steel pipe with a height of 100-150mm. The supporting column is welded to the main beam and located at the connection between the main beam and the secondary beam.

[0016] Furthermore, the flexible support pad is a polyurethane foam board or a rubber board with a thickness of 20-25mm, and the flexible support pad covers the top of each support column.

[0017] The transport bracket device for the ultra-thin high-performance concrete base plate of this utility model has at least the following beneficial effects:

[0018] 1. By combining "rigid frame + elastic support", the traditional point support or line support is transformed into surface support, which greatly reduces the deflection of the ultra-thin high-performance concrete base plate during storage and transportation, and avoids the risk of stress concentration and cracking.

[0019] 2. The overall packaging method greatly improves loading and unloading efficiency; the main body of the device is made of steel, which is durable and can be recycled thousands of times. The cost per transport after dilution is extremely low, which is in line with the concept of green construction.

[0020] 3. The use of fixed transport brackets prevents the overall slippage and overturning of the concrete base plate stack; the formed three-dimensional binding space ensures the slippage of the ultra-thin high-performance concrete base plate. Attached Figure Description

[0027] 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.

[0028] See below. Figures 1-4 The present invention provides a detailed description of the transport bracket device for ultra-thin high-performance concrete base plates.

[0029] The transport bracket device for ultra-thin high-performance concrete base plates of this utility model includes a main support frame, a multi-point elastic support system, a limiting system, and a fixing system.

[0030] The main support frame is a three-dimensional grid frame welded from several parallel main beams 1 and several secondary beams 2 connecting the main beams 1, used to support the stack of high-performance concrete base plates 6 formed by stacking concrete base plates.

[0031] The multi-point elastic support system includes multiple support columns 3 arranged on the upper surface of the main support frame and a flexible support pad layer 4 laid on top of all the support columns 3.

[0032] The limiting system of this utility model is a flexible band 5, which connects with the main support frame to form a three-dimensional binding space to fix the stack of high-performance concrete base plates 6. The limiting system consists of multiple flexible bands 5 arranged perpendicular to the length of the high-performance concrete base plates along the stack and multiple flexible bands 5 arranged parallel to the length of the high-performance concrete base plates along the stack. Flexible pads are provided at the contact points between the flexible bands 5 and the high-performance concrete base plates 6.

[0033] Both the main beam 1 and the secondary beam 2 are made of rectangular steel pipes. The center-to-center distance between two adjacent main beams 1 is 200-250mm, and the center-to-center distance between two adjacent secondary beams 2 is 600-800mm. The main beams 1 and secondary beams 2 are welded to form a three-dimensional grid frame, with the main beam 1 on top and the secondary beam 2 on the bottom.

[0034] The transport bracket device of this utility model is set with different dimensions according to the size of the high-performance concrete base plate 6. In one specific embodiment, the width of the high-performance concrete base plate 6 is 1200mm, and 6 main beams 1 are used. The secondary beams 2 are appropriately increased or decreased according to the length of the high-performance concrete base plate 6.

[0035] The supporting column 3 is made of rectangular steel pipe with a height of 100-150mm, welded to the main beam 1, and located at the connection between the main beam 1 and the secondary beam 2. The flexible support pad 4 is made of polyurethane foam board or rubber board with a thickness of 20-25mm and a Shore hardness of A60-A80. This flexible support pad 4 covers the top of each supporting column 3 and can effectively absorb vibration energy.

[0036] The fixing system of this utility model is set at the bottom of the main support frame for fixed connection with the transport vehicle. The fixing system includes angle steel 9 located at the bottom of the four corners of the main support frame. The angle steel 9 is connected to the secondary beam 2 via tie rods 8. The secondary beam 2 has elliptical holes 11 through which the tie rods 8 pass. The angle steel 9 is fixed to the transport vehicle's platform 12 by spot welding, thus forming a quick connection. Therefore, the placement of the transport bracket device of this utility model on the transport vehicle is unrestricted.

[0037] In addition, trusses 7 are connected to the high-performance concrete base plate 6. The spacing between the trusses 7 is 200mm, and the distance from the truss 7 to the edge of the high-performance concrete base plate 6 is 100mm. Three wooden blocks 10 are set between the ultra-thin high-performance concrete base plates. The wooden blocks 10 are perpendicular to the length direction of the high-performance concrete base plate 6, which reduces the contact between adjacent high-performance concrete base plates 6 and trusses 7 and increases the friction.

[0038] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
