Problems solved by technology

According to the actual situation, the sealing effect of the sealing cover is greatly affected by the construction and bridge vibration, especially in the service condition of the short suspension bridge at the mid-span of the suspension bridge with high-frequency vibration and large deflection at the beam end, the bolts of the sealing cover are affected by vibration and vibration. The effect of deflection is easy to loosen and cause the seal to be ineffective

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like figure 1 As shown, the sling anchoring structure in this embodiment mainly includes an anchor cup 1 and an annular waterproof sleeve 2, the rear end of the anchor cup is a tapered anchoring cavity, the front end of the anchoring cavity is an extension tube 2 with a length of 50mm-250mm, and the extension tube 2 As a part of the anchor cup 1, it is integrally formed with the anchor cavity.

[0019] The cable body 6 passes through the extension tube 2 and is then anchored in the anchoring cavity, and the cable body 5 in the anchoring cavity is stripped of the sheath and then spread out in a tapered shape and anchored in the anchoring cavity. The sheath of the cable body located in the extension tube 2 is partially stripped off, and the sealing packing 4 is used to seal it in the extension tube 2, and the gap between the extension tu...

Abstract

The durable sling anchoring structure comprises an anchor cup and an annular waterproof sleeve, an extension cylinder is integrally formed at the front end of an anchoring cavity of the anchor cup, asling body penetrates through the extension cylinder and then is anchored in the anchoring cavity, and the gap between the sling body and the extension cylinder is filled with sealing filler; whereinthe end part of the extension cylinder is sealed by the annular waterproof cover, the matching surface of the annular waterproof cover and the cable body is provided with a sealing ring or the annularwaterproof cover is directly welded outside the cable body, the matching surface of the annular waterproof cover and the extension cylinder is provided with a sealing ring, and the matching surface of the extension cylinder and the cable body is provided with a sealing ring. The sling anchoring structure designed by the invention has the advantages of few parts, few connecting structures of the parts, more stable overall structure, high deformation resistance and firmer sealing effect.

Description

technical field [0001] The invention relates to an anchoring structure of a wire bundle sling. Background technique [0002] Suspension bridge suspension cables, especially short suspension cables, due to the limitation of the structural system, the stress of the suspension cables is very complicated, and the position of the mid-span is affected by the swing of the beams in the direction of the transverse bridge and along the direction of the bridge, which is easy to cause the lower end of the short suspension cables of the mid-span and The joint position of the anchor cup causes bending damage, which leads to the failure of the sealing structure and causes corrosion fatigue damage. The existing sling anchorage structure system needs to be redesigned and optimized in order to find a method that can fully meet the current requirements for the use of short slings at the mid-span of suspension bridges. Structure. [0003] The anchoring structure of the cable body in the sling ...
