Description

Technical Field

[0001] The utility model belongs to the technical field of pipe segment steel moulds, and in particular relates to a protection device for a pipe segment steel mould limit block. Background Art

[0002] Segment steel molds are special molds used to produce concrete segments in tunnel construction. Segments are an important part of the tunnel structure, used to form the wall or top of the tunnel. Their quality and precision directly affect the safety and stability of the tunnel. Therefore, the design and manufacture of segment steel molds are of vital importance to tunnel construction.

[0003] The 6600*5900mm segment of Shanghai Metro has additional limit holes on the side panels of the mold due to the needs of the segment connection structure. The design sets a flat slope section at a width of 34mm in consideration of the stress of the matching limit parts. However, this design structure will cause a large range of damage to the segment due to the demoulding angle, affecting the appearance quality and connection stress. Utility Model Content

[0004] The purpose of the utility model is to increase limiting holes at the side plates of the mold in order to solve the needs of the existing pipe segment connection structure. In consideration of the stress of the matching limiting parts, a flat slope section is set at a width of 34 mm. However, this design structure may cause a large range of damage to the pipe segment due to the demoulding angle, affecting the appearance quality and the connection stress, and thus a protective device for the pipe segment steel mold limiting block is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a protective device for a segment steel mold limit block, comprising a steel mold, a limit hole is arranged on the steel mold, a limit piece is connected in the limit hole, a flat slope section is arranged on the limit piece, a connecting groove is arranged on the outer side of the flat slope section, and a rubber ring is arranged at the connecting groove.

[0006] As a further description of the above technical solution:

[0007] The rubber ring is provided with a plurality of connection holes, and the limiting member and the rubber ring are connected via a fixing member passing through the connection holes.

[0008] As a further description of the above technical solution:

[0009] A plurality of the connecting holes are arranged in a ring shape.

[0010] As a further description of the above technical solution:

[0011] The rubber ring and the limiting member are in the shape of a central hole. The central hole of the limiting member is connected with a connecting pipe extending inwardly. The connecting pipe is closed toward the inner side of the steel mold.

[0012] As a further description of the above technical solution:

[0013] The radius of the rubber ring is greater than the radius of the limiting member.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] 1. In the present invention, in order to solve the above-mentioned problem of die drawing without changing the stress structure of this part, we have optimized the structure of the limiter and set a rubber ring in the flat slope section so that when the formwork is opened, the concrete forms a soft contact with the rubber ring on the limiter, thus preventing the segment from being damaged after demoulding without affecting its stress structure, and achieving a good effect.

[0016] 2. In the utility model, a pre-buried sleeve is provided extending inwardly from the middle hole of the limiter, so that after pouring concrete into the steel mold, holes are reserved in the formed pipe segment. BRIEF DESCRIPTION OF THE DRAWINGS
