removable anchor

Abstract

The invention relates to an anchorage device used in buildings and civil construction, and discloses a removing type anchorage device. The removing type anchorage device comprises a water-proof cover, an anchor ring extrusion sleeve, a spring and a head sleeve, and further comprises a plate spring. A cone-shaped ditch with the narrow upper portion and the wide lower portion is formed inside the water-proof cover. The anchor ring extrusion sleeve is composed of three clamping pieces of the same shape. The anchor ring extrusion sleeve is of a cone shape with the narrow upper portion and the wide lower portion. An annular concave groove is formed in the periphery of the lower end of the anchor ring extrusion sleeve. An anchor ring fixing ring is arranged in the annular concave groove. The plate spring is arranged between the anchor ring extrusion sleeve and the spring. The external diameter of the plate spring is the same with the external diameter of the lower end of the anchor ring extrusion sleeve. The head sleeve is a cylinder with the open upper portion and the closed lower portion. The removing type anchorage device is very simple in overall structure in the machining and manufacturing process, high in working efficiency of assembling and disassembling, and capable of reducing manufacturing processes, saving production cost, and achieving the effects of facilitating operation and shortening time.

Description

technical field [0001] The invention relates to an anchor used in building and civil engineering construction, in particular to a removable anchor. Background technique [0002] When constructing the underground structure of large structures such as high-rise buildings and subways, according to the previous technology, H beams should be vertically fixed around the surrounding depth as the anti-slump protection wall or anti-seepage wall while deepening the underground depth. The H beam hinders the construction of equipment and causes problems such as low work efficiency. The underground diaphragm wall construction method needs to clean up the irregular wall surface, which will cause noise and dust. Therefore, recently, anchors are mostly used as diaphragm walls for construction. [0003] That is, in the construction of underground structures of large structures such as high-rise buildings and subways, in the process of erecting anti-slump retaining walls or anti-seepage wall...

AI Technical Summary

Problems solved by technology

[0007] The present invention aims at the problems of increased production, processing and assembly difficulty and reduced economic efficiency caused by the complicated anchor structure in the prior art, and if the dismantling tension member is removed before the dismantling occurs due to operational errors and other reasons When the tension member is loose, slippage may be caused by being pulled, and the receding central material cannot be retreated, and the tension member for disassembly cannot be removed; the process of removing the tension member is too cumbersome, providing a simple structure , can improve the convenience of production, assembly and use, and ensure mechanical reliability and ease of disassembly operations.
