Description

Technical Field

[0001] This utility model belongs to the field of corrugated steel plate technology, and more specifically, it relates to an enhanced corrugated steel plate structure suitable for heavy loads. Background Technology

[0002] Corrugated steel sheet is a new type of building material. It boasts good ductility and strong resistance to deformation, along with advantages such as quick and convenient installation, time-saving construction, low cost, and environmental friendliness. Therefore, its widespread use in transportation and municipal engineering for culverts, tunnels, underground passages, and underground pipelines has become a trend. However, existing corrugated steel sheet structures exhibit high flexibility but low stiffness and load-bearing capacity. For environments requiring high load-bearing capacity, such as heavy-duty mining areas, the load-bearing capacity of a single layer of corrugated steel sheet is insufficient, making it unsuitable for heavy-duty environments. Therefore, reinforcing structures are needed to improve the structural strength of the corrugated steel sheet and meet heavy-duty requirements. Utility Model Content

[0033] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Please refer to the following: Figures 1 to 6 The present invention provides a reinforced corrugated steel plate structure suitable for heavy loads. This reinforced corrugated steel plate structure includes a corrugated steel plate body 1 and reinforcing steel ribs 2. The reinforcing steel ribs 2 are connected to the inner and / or outer sides of the corrugated steel plate body 1. The reinforcing steel ribs 2 are connected to at least two adjacent crests or troughs on the corrugated steel plate body 1 by bolts 3. The middle portion of the reinforcing steel ribs 2 abuts against a trough or crest on the corrugated steel plate body 1 opposite to the middle portion of the reinforcing steel ribs 2, thereby enhancing the structural strength of the corrugated steel plate body 1.

[0035] This utility model provides a reinforced corrugated steel plate structure suitable for heavy loads. Compared with the prior art, it is applied to circular cross-section culverts, box-section culverts, or horseshoe-section culverts. By adding reinforcing steel ribs 2 to the corrugated steel plate body 1, multiple ribs can be added according to specific usage conditions. This can improve the structural strength of the corrugated steel plate body 1, making it suitable for heavy load environments. It solves the technical problem that the corrugated steel plates used in the prior art have low load-bearing capacity and are not suitable for heavy load environments. It has the technical effect of improving the load-bearing capacity and structural strength of the corrugated steel plate body 1, adapting to heavy load environments, and meeting usage requirements.

[0036] In some embodiments, please refer to Figures 1 to 6The reinforcing steel rib 2 includes an I-beam 21, multiple sets of steel plates 22, and multiple reinforcing blocks 23. The reinforcing blocks 23 are in the shape of a right trapezoid. The length direction of the I-beam 21 is set along the length direction of the trough or crest of the corrugated steel plate body 1. The side of the I-beam 21 near the trough or crest of the corrugated steel plate body 1 is set into an arc-shaped structure 24, and the arc shape of the arc-shaped structure 24 matches the arc shape of the trough or crest of the corrugated steel plate body 1 and they are closely attached to each other. Multiple sets of steel plates 22 are respectively set on both sides of the I-beam 21. The steel plates 22 are arranged parallel to the bottom surface of the I-beams 21. The ends of the multiple steel plates 22 near the I-beams 21 are respectively connected to the middle of the I-beams 21. Each set of steel plates 22 has mounting holes 25, through which bolts 3 are adapted to pass and connect to the corrugated steel plate body 1. Multiple reinforcing blocks 23 are respectively connected to the area enclosed between the I-beams 21 and the steel plates 22. The reinforcing blocks 23 are adapted to enhance the structural strength of the I-beams 21 and the steel plates 22, thereby enhancing the structural strength of the corrugated steel plate body 1. The structure of the I-beams 21 in this embodiment differs from that of I-beams in the prior art. The upper surface of the I-beams 21 is arc-shaped, i.e., arc-shaped structure 24, while the upper surface of I-beams in the prior art is planar. The arc shape facilitates the contact with the arc of the troughs or crests of the corrugated steel plate body 1, thereby increasing the support area and enhancing the structural strength of the corrugated steel plate body 1. In this embodiment, a set of reinforcing steel ribs 2 are connected to two adjacent crests or troughs of the corrugated steel plate body 1, or they can be connected to three or more crests or troughs. The middle position of the I-beam 21 refers to the waist position of the I-beam 21. Multiple sets of steel plates 22 are symmetrically arranged on both sides of the I-beam 21, and one end of each plate can be welded to the middle of the I-beam 21. The bolts 3 pass through the mounting holes 25 and through the crests or troughs of the corrugated steel plate body 1, thereby fixing the reinforcing steel ribs 2 to the corrugated steel plate body 1.

[0037] Specifically, a gasket 4 is provided between the steel plate 22 and the corrugated steel plate body 1, which can play a role in anti-slip and anti-detachment.

[0038] In some embodiments, please refer to Figures 1 to 6 The space formed between the corrugated steel plate body 1 and the reinforcing steel rib 2 is filled with reinforcing material 5. The reinforcing material 5 is concrete, glass fiber, asbestos fiber, or carbon fiber. The reinforcing material 5 can enhance the structural strength of the corrugated steel plate body 1. The corrugated steel plate body 1, the reinforcing steel rib 2, and the reinforcing material 5 can be regarded as an integral structure, which can greatly enhance the structural strength of the corrugated steel plate body 1.

[0039] Preferably, two or more of the reinforcing materials 5 mentioned above can be used during filling.

[0040] In some embodiments, please refer to Figures 1 to 6The corrugated steel plate body 1 and / or reinforcing steel rib 2 are provided with grouting holes 6, which connect the space formed between the corrugated steel plate body 1 and the reinforcing steel rib 2. By providing grouting holes 6, reinforcing material 5 can be easily filled into the space, and the grouting holes 6 can be sealed after filling.

[0041] In some embodiments, please refer to Figures 1 to 6 A plug 7 is installed inside the grouting hole 6 to seal the grouting hole 6. When filling is required, the plug 7 is removed; when filling is not required, the grouting hole 6 is sealed.

[0042] To further enhance the structural strength of the corrugated steel plate body 1, in some embodiments, please refer to... Figures 1 to 6 The reinforcing steel rib 2 is threadedly connected to a reinforcing column 8, which is suitable for abutting or pushing against the corrugated steel plate body 1 to enhance the structural strength of the corrugated steel plate body 1. The reinforcing column 8 is connected to the steel plate 22 and is symmetrically arranged with the middle of the I-beam 21 as the axis of symmetry. The function of the reinforcing column 8 is twofold: first, it can combine with the reinforcing material 5 to form a whole; second, it can support the corrugated steel plate body 1, reducing deformation between the reinforcing steel rib 2 and the corrugated steel plate body 1, and improving the structural strength of the corrugated steel plate body 1.

[0043] In some embodiments, please refer to Figures 1 to 6 The reinforcing column 8 includes a reinforcing bolt 81 and a column body 82. The reinforcing bolt 81 passes through the reinforcing steel rib 2 and is threadedly connected to the reinforcing steel rib 2. The two ends of the reinforcing bolt 81 are located on both sides of the reinforcing steel rib 2, and the end of the reinforcing bolt 81 that is away from the corrugated steel plate body 1 is the screw-in end. By screwing the screw-in end of the reinforcing bolt 81, it has the freedom to move along the height or thickness direction of the reinforcing steel rib 2. One end of the column body 82 is connected to the other end of the reinforcing bolt 81, and the other end is adapted to abut or push against the corrugated steel plate body 1. By screwing the reinforcing bolt 81, the pushing force of the column body 82 on the corrugated steel plate body 1 can be adjusted. The middle part of the reinforcing bolt 81 passes through the steel plate 22 and is threadedly connected to the steel plate 22. The screw-in end is located on the outside of the steel plate 22, and the inner end of the reinforcing bolt 81 (i.e., the end located in the space) is connected to the column body 82. By using tools to tighten the reinforcing bolts 81, the reinforcing bolts 81 can push the column 82 to move, thereby abutting against the corrugated steel plate body 1 and providing support for the corrugated steel plate body 1, effectively preventing its deformation. The column 82 has a slope, which can maximize the contact area with the corrugated steel plate body 1, thereby improving the structural strength of the corrugated steel plate body 1.

[0044] In some embodiments, please refer to Figures 1 to 6The column 82 includes a cylinder 821 and a cone 822. One end of the cylinder 821 has a groove 823 extending axially inwards along the depth direction of the cylinder 821. The inner wall of the groove 823 has internal threads. One end of the reinforcing bolt 81 is inserted into the groove 823 and threadedly connected to the internal threads. The cone 822 is connected to the other end of the cylinder 821. The cone 822 has a flat end and a pointed end. The flat end is connected to the end of the cylinder 821, and the pointed end faces away from the cylinder 821. The outer wall of the cone 822 is suitable for contacting or pushing against the surface of the corrugated steel plate body 1. The diameter of the flat end of the cone 822 is the same as or approximately the same as the diameter of the cylinder 821, allowing them to be fixedly connected. One end of the reinforcing bolt 81 is inserted into the groove 823, and by tightening the reinforcing bolt 81, it can be fixedly connected to the cylinder 821. By tightening the reinforcing bolt 81, the distance between the cone 822 and the corrugated steel plate body 1 can be adjusted, thereby adjusting the pushing force on the corrugated steel plate body 1, which in turn supports the corrugated steel plate body 1 and enhances its strength.

[0045] In some embodiments, please refer to Figures 1 to 6 The outer wall of the cylinder 821 is evenly distributed with multiple anti-slip teeth 824. If the space is filled with reinforcing material 5, the reinforcing material 5 and the anti-slip teeth 824 will contact each other and combine to form a whole. The anti-slip teeth 824 can increase the contact area between the cylinder 821 and the reinforcing material 5, thereby preventing the reinforcing material 5 from deforming in the space, so as to improve the structural strength of the corrugated steel plate body 1.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
