Description

Technical Field

[0001] The utility model relates to the technical field of corrugated steel pipes, and specifically relates to a device for strengthening internal steel shapes of a corrugated steel pipe. Background Technique

[0002] A corrugated pipe refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and telescoping direction. Corrugated pipes are widely used in instruments and meters. Their main purpose is to serve as a measuring element for pressure measuring instruments, converting pressure into displacement or force. The wall of the corrugated pipe is relatively thin, with high sensitivity, and the measurement range is from dozens of pascals to dozens of megapascals. Its open end is fixed, and the sealed end is in a free state, and an auxiliary helical spring or reed is used to increase elasticity. If the elasticity of the element is non-linear, then its stiffness is no longer as simple as a constant, and it will also change due to the change of the load. Most projects use corrugated pipes, and such stiffness is also divided into bending stiffness, axial stiffness, and torsional stiffness.

[0003] In the prior art, such as CN218208229U, a reinforced cold-formed corrugated steel pipe, by arranging a first reinforcing steel pipe in the first trough of the corrugated steel pipe body, the stiffness is improved. By arranging a second reinforcing steel pipe in the second trough of the corrugated steel pipe body, the stiffness is further improved. The connecting piece is a semi-circular hoop and is connected to the corrugated pipe body through bolts, which is convenient for installation and disassembly.

[0004] However, there are still certain deficiencies in the use of this corrugated steel pipe. Among them, the first reinforcing steel pipe is arranged outside the corrugated pipe through a semi-circular hoop, and the inside of the corrugated pipe cannot be strengthened. The contact surface between the first reinforcing steel pipe and the corrugated cross-section is too small to completely conduct the received pressure, resulting in a large gap between the actual strengthening effect and the theoretical strengthening effect.
