Description

Technical Field

[0001] The invention relates to the field of corrugated plates, in particular to a novel metal expansion type corrugated plate. Background Art

[0002] Metal corrugated sheet is a corrugated sheet with a specified diameter (or span) formed by pressing steel sheet into a wave shape on a special corrugating machine, and then forming it on a forming machine. Several sections of metal corrugated sheet with a certain length are connected with fasteners to form a corrugated pipe. For the same material and the same thickness of corrugated sheet structure, the shallower the trough depth or the lower the wave peak height, the smaller its bearing capacity; conversely, the greater the bearing capacity, the deeper the trough depth or the higher the wave peak height, and the greater the amount of steel plate used for the same length of culvert.

[0003] In the prior art, under high fill, the use of a single-wave corrugated metal plate will cause settlement due to uneven foundation, resulting in large-scale deformation of the metal corrugated plate, which poses a serious safety hazard. Different types of corrugated metal plates are usually connected by welding, etc. Therefore, when the metal corrugated plate is manufactured, it is impossible to freely customize corrugated plate connectors with different waveforms according to actual needs.

[0004] Therefore, it is necessary to provide a new type of metal expansion corrugated plate to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a new type of metal expansion corrugated plate.

[0006] The novel metal expansion corrugated plate provided by the present invention comprises: a metal corrugated plate, both ends of which are fixed with metal connecting plates, the metal connecting plates are provided with connecting mechanisms, the surface of the metal connecting plates is provided with installation holes at intervals, and a corrugated tube is provided through the installation holes.

[0007] Furthermore, the bellows is welded in the mounting hole, and both ends of the bellows extend out of the mounting hole, and flanges are installed at both ends of the bellows.

[0008] Furthermore, the connection mechanism specifically comprises a connection seat and fixing bolts fixed at intervals on the metal connection plate, a plurality of groups of threaded holes are fixed at intervals on the surface of the connection seat, and the two connection seats are threadedly connected by fixing bolts.

[0009] Furthermore, at least one set of first waveforms and second waveforms is arranged on the metal corrugated plate, and the first waveforms and the second waveforms are arranged alternately.

[0010] Furthermore, the radius of the first waveform is greater than that of the second waveform.

[0011] Furthermore, the radius length of the radius of the first waveform is 52 to 123 mm, and the radius length of the radius of the second waveform is 19 to 52 mm.

[0012] Furthermore, the distances between two adjacent peaks of the first waveform and the second waveform are equal.

[0013] Furthermore, the peak height of the first waveform is 55 to 255 mm, and the trough depth of the second waveform is 52 to 252 mm.

[0014] Compared with the related art, the novel metal expanded corrugated plate provided by the present invention has the following beneficial effects:

[0015] 1. When connecting two metal corrugated plates, the device does not need to use the traditional welding method, but aligns the two metal corrugated plates so that the two corresponding connecting seats are located in the same plane. At this time, the corresponding fixing bolts are screwed into the threaded holes to complete the connection of the two metal corrugated plates. The operation is simple and convenient. When one of the metal corrugated plates is damaged, it only needs to remove the fixing bolts to replace it. Combined with the setting of the expansion joint, the metal corrugated plate has an expansion function when facing water accumulation in the foundation.

[0016] 2. This device solves the problem of large-area deformation of single-wave corrugated metal plates due to settlement caused by uneven foundation in high-fill environments to a certain extent, making it suitable for different geology and terrains. It not only increases the scope of use of metal corrugated plates, but also improves the safety of pipeline use to a certain extent. It has a simple structure and is easy to install.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the novel metal expansion corrugated plate provided by the present invention; Figure 2 for Figure 1 The structural schematic diagram of A shown; Figure 3 for Figure 1 The structural diagram of B shown; Figure 4 This is a side view of a novel metal expansion corrugated plate provided by the present invention. It comprises: a metal corrugated plate 1.

[0024] In the specific implementation process, Figure 1-Figure 4 As shown, metal connecting plates 2 are fixed at both ends of the metal corrugated plate 1, and a connecting mechanism is arranged on the metal connecting plate 2. Mounting holes 3 are arranged at intervals on the surface of the metal connecting plate 2, and a corrugated pipe 4 is arranged inside the mounting hole 3. When connecting two metal corrugated plates 1, the device does not need to use the traditional welding method, but aligns the two metal corrugated plates 1 so that the two corresponding connecting seats 6 are located in the same plane. At this time, the two metal corrugated plates 1 can be connected by screwing the corresponding fixing bolts 8 into the threaded holes 7. The operation is simple and convenient, and when one of the metal corrugated plates 1 is damaged, it only needs to remove the fixing bolts 8 for replacement. The corrugated pipe 4 is welded in the mounting hole 3, and both ends of the corrugated pipe 4 extend out of the mounting hole 3. Flanges 5 are installed at both ends of the corrugated pipe 4. By connecting the top of the corrugated pipe 4 to a drainage device, when the foundation area where the corrugated pipe 4 is located is severely soaked in water, it can be drained through the corrugated pipe 4 to prevent the corrugated pipe 4 from being damaged. The connecting mechanism is specifically a connecting seat fixed on the metal connecting plate 2 at intervals. 6 and fixing bolts 8, a plurality of groups of threaded holes 7 are fixed at intervals on the surface of the connecting seat 6, and the two connecting seats 6 are threadedly connected by fixing bolts 8. At least one group of first waveforms 9 and second waveforms 10 are arranged on the metal corrugated plate 1, and the first waveforms 9 and the second waveforms 10 are arranged alternately. The radius length of the first waveform 9 is 52 to 123 mm, the radius length of the second waveform 10 is 19 to 52 mm, the distance between two adjacent peaks of the first waveform 9 and the second waveform 10 is equal, the peak height of the first waveform 9 is 55 to 255 mm, and the trough depth of the second waveform is 52 to 252 mm. By arranging waveforms of different sizes on the same metal corrugated plate 1, its bearing capacity is increased, and the problem of large-area deformation of the metal corrugated plate 1 caused by settlement of the metal corrugated plate 1 with a single waveform in a high fill environment due to uneven foundation is solved, so that it is suitable for different geology and terrain, the use range of the metal corrugated plate 1 is increased, and the safety of pipeline use is improved. It has a simple structure and is easy to install.

[0025] The working principle provided by the present invention is as follows: when connecting two metal corrugated plates 1, the device does not need to use the traditional welding method, but aligns the two metal corrugated plates 1 so that the two corresponding connecting seats 6 are located in the same plane. At this time, the corresponding fixing bolts 8 are screwed into the threaded holes 7 to complete the connection of the two metal corrugated plates 1. The operation is simple and convenient. When one of the metal corrugated plates 1 is damaged, it only needs to remove the fixing bolts 8 to replace it. By providing waveforms of different sizes on the same metal corrugated plate 1, its bearing capacity is increased, and to a certain extent, the problem of large-area deformation of the metal corrugated plate 1 caused by settlement due to uneven foundation of the single-waveform metal corrugated plate 1 in a high-fill environment is solved, so that it is suitable for different geology and terrain, which not only increases the scope of use of the metal corrugated plate 1, but also improves the safety of pipeline use to a certain extent. It has a simple structure and is easy to install.
