Water-proof sealing cover

Abstract

The invention discloses a water-proof sealing cover for a stay cable or a lifting rod. The water-proof sealing cover comprises a fixing sleeve, sealing rubber, a compression ring and a corrugated sealing sleeve, wherein the fixing sleeve, the compression ring and the sealing rubber are integral structures or two-half structures; the corrugated sealing sleeve is the integral structure or the two-half structure; during use, the corrugated sealing sleeve with the two-half structure is connected into a whole through a bolt; and the sealing rubber is arranged between the fixing sleeve and the compression ring. Through pre-tensioning force between the fixing sleeve and the compression ring, the sealing rubber is tightly clamped in a cable body, so that the fixing sleeve, the compression ring and the sealing rubber are fixed with the cable body and then are connected with a pre-embedded pipe through the corrugated sealing sleeve. The corrugated sealing sleeve has a plurality of degrees of freedom, the influence of constraint on the cable body is relatively low, and a relatively good sealing effect can be achieved. Furthermore, due to the special structure of the corrugated sealing sleeve, the problem that the water-proof cover cannot be mounted or a using effect cannot be achieved after the water-proof cover is mounted because the cable body is not in the middle of the pre-embedded pipe during practical mounting is solved.

Description

technical field [0001] The invention relates to a waterproof sealing cover suitable for the lower end pre-embedded pipe or the upper end pre-embedded pipe of a stay cable or a suspender. Background technique [0002] The waterproof device is a very important sealing member during the installation and use of the cable. At present, in the process of design and use of cables, there is a way to use a rigid waterproof cover to fasten it on the pre-embedded nozzle to prevent rainwater from entering. It is usually only used at the pre-embedded pipe at the beam end; The pipe is completely fixed, so the seal is incomplete or the seal is damaged due to the vibration of the cable body; in addition, because the cable body is not concentric with the embedded pipe diameter, it will cause difficulty in installation or unsatisfactory waterproof effect; moreover, its processing cost is high.

AI Technical Summary

Problems solved by technology

At present, in the process of design and use of cables, there is a way to use a rigid waterproof cover to fasten it on the pre-embedded nozzle to prevent rainwater from entering. It is usually only used at the pre-embedded pipe at the beam end; The pipe is completely fixed, so the seal is incomplete or the seal is damaged due to the vibration of the cable body; in addition, because the cable body is not concentric with the embedded pipe diameter, it will cause installation difficulties or unsatisfactory waterproof effect; moreover, the processing cost is relatively high

The patent publication number is: CN 201660849 U's utility model patent discloses a "rubber waterproof device for bridge cables", which can be used for the pre-embedded pipes at the beam end and the pre-embedded pipes at the tower end of the cables, although it can partially overcome the The shortcomings of the rigid waterproof cover, but there are still the following shortcomings: 1. The transition between the cone and the cylinder cannot be completely sealed; 2. When the cable body and the embedded pipe diameter are not concentric, it is easy to make the rubber Tension on one side reduces the use effect of rubber; 3. The sealing effect of clamps at both ends of the size is not good, and it is easy to damage the rubber
