Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction, and in particular relates to a flexible connection device for a corrugated steel web and inner lining concrete. Background Art

[0002] In order to prevent early cracks in the lining concrete, rubber-wrapped weld studs are used as flexible connection structures between the corrugated steel web and the lining concrete, allowing shear slip and interface shrinkage to occur. The flexible rubber weld studs have a pull-out resistance but not a shear resistance, preventing the lining concrete from separating from the corrugated steel web.

[0003] After the existing welding nails are welded to the steel structure, a lot of welding slag will appear at the welding position. The current cleaning method is to manually clean it by knocking around the welding nails with a spatula. This method is relatively cumbersome and has low work efficiency. Therefore, it has great limitations in actual use and has room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a flexible connection device for a corrugated steel web and an inner lining concrete, so as to solve the problem of inconvenience in operation when cleaning welding slag between welding nails and steel structures proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a flexible connection device between a corrugated steel web and an inner lining concrete, comprising a nail body; a rubber ring, which is sleeved on the nail body; a cleaning ring, which is also sleeved on the nail body and is located at the bottom of the rubber ring; the thickness of the cleaning ring decreases toward the bottom end, that is, when the cleaning ring removes the welding slag between the nail body and the steel structure, the thinner part at the bottom end of the cleaning ring can be used for punching and removing; end plates are also fixed at both ends of the end plate, and the staff can use the end plates to knock on the cleaning ring to cut off the welding slag and protruding welding points.

[0006] Preferably, positioning ring grooves are opened equidistantly upward from the bottom of the nail body, and the depth of the positioning ring grooves is 0.1 mm. When welding the nail body to the steel structure, the positioning ring grooves can be used to assist in judging the heights of the welds and welding slag after welding, so as to quickly determine whether the welding is unqualified. That is, when the heights of the welding slag and the weld exceed the positioning ring groove at the lowest position, it indicates that it is qualified, and when the positioning ring groove exceeds this position, it indicates that the welding is unqualified.

[0007] Preferably, at least one protrusion is fixed on the surface of the nail body, and the bottom end of the cleaning ring overlaps the protrusion to limit the cleaning ring and prevent it from falling and affecting normal welding. In the later normal welding, the end plate is knocked so that the cleaning ring will first cut off the protrusion, and then the welding slag and welding spots will be cut off. The protrusion is at the top of the positioning ring groove to prevent the cleaning ring from contacting the positioning ring groove.

[0008] Preferably, the end plate extends horizontally toward the outside of the nail body, and the length of the end plate exceeds the outer diameter of the rubber ring, thereby ensuring that it can be struck normally.

[0009] Preferably, an alignment groove is provided at an equal angle on the bottom end surface of the rubber ring, and the longitudinal section of the alignment groove is triangular, which has better friction and higher stability than a flat surface.

[0010] Preferably, an extension ring is also provided on the nail body, and the extension ring is located between the cleaning ring and the rubber ring. Through the setting of the extension ring, the length of the rubber ring can be adjusted according to actual use requirements to realize protection of the nail body with different requirements and achieve flexible connection.

[0011] Preferably, the extension ring has at least one end face fixed with an alignment protrusion, which engages with the alignment groove or abuts against the contact surface. When the alignment protrusion engages with the alignment groove, the extension ring will fit with the contact surface in a planar manner, which can achieve better fit. On the contrary, if the alignment protrusion is not connected, the extension ring will abut against the contact surface in the direction of the protrusion, which can achieve higher stability. The corresponding method is selected according to actual needs.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The designed cleaning ring can quickly remove the welding slag generated between the welding nails and the steel structure, and the designed end plate can be knocked by the staff, which is very convenient to operate. When not in use, it can be placed normally without affecting the welding of the welding nails and the steel structure, thus improving the overall flexibility and practicality.
