Intelligent tension tool anchor capable of making penetration of prestressed reinforcing steel easy

Abstract

The invention discloses an intelligent tension tool anchor capable of making penetration of prestressed reinforcing steel easy. The tool anchor comprises a tool anchor ring and tool jackets, circular-truncated-cone-shaped tool anchor eyes run through the tool anchor ring, the shapes of the tool jackets are matched with those of the inner walls of the tool anchor eyes, the tool jackets are sleevedwith the tool anchor eyes, and prestressed reinforcing steel engagement holes which are coaxial with the tool anchor eyes are formed in the tool jackets; the tool jackets are formed by circumferentially assembling at least two tool clamping pieces, clamping piece lifting assemblies are connected with the big ends of the tool jackets, clamping piece restoration components are connected with the small ends of the tool jackets, and lifting operation pieces are arranged between the clamping piece lifting assemblies and the tool anchor ring. The intelligent tension tool anchor has the advantages that the tool clamping pieces are easily pulled to the big ends of the tool anchor eyes, so that the prestressed reinforcing steel engagement holes are expanded, and penetration of prestressed reinforcing steel is easy; after use, the clamping piece restoration components can help the tool clamping pieces automatically get back into work anchor eyes, and the intelligent tension tool anchor is particularly suitable for penetration and clamping of multiple pieces of prestressed reinforcing steel on the multi-hole tool anchor.

Description

technical field [0001] The invention relates to a tool in the field of building and bridge construction, in particular to an intelligent tensioning and wearable tool anchor. Background technique [0002] Prestressed tensioning technology is widely used in building and bridge construction. The use of prestressed construction can slow down the occurrence and expansion of concrete cracks and prolong the service life. However, the prestressed tensioning construction process has high requirements on materials and construction techniques, and the problem of prestress loss is more likely to occur. The prestress loss generally occurs at the end of the traditional prestress loading, and the clamp and the anchor ring are tightened due to the retraction of the prestress tendons, resulting in the loss of the loaded prestress. At present, in order to solve the problem of prestress loss in the construction process, it is often necessary to use the method of super tension, even if the max...

Problems solved by technology

However, the hypertension method often does not determine the amount of stress loss, cannot guarantee that the final stress meets the design requirements, and is prone to breakage or damage to the anchorage, so the hypertension method is not reliable
