Problems solved by technology

In addition, the traditional anchor block cannot be installed on the precision-rolled rebar, which brings troubles to the installation and construction. If the installation gap is large, there is a risk of the anchor falling off, which brings serious safety hazards to the construction personnel.

Abstract

The invention discloses a steel bar clip pre-stress tensioning anchor block. The steel bar clip pre-stress tensioning anchor block comprises a ribbed slab, the ribbed slab is respectively provided with a pre-stress crude steel bar wire anchor and a pre-embedded bolt, one side surface of the ribbed slab is provided with a pre-embedded leveling steel plate, the pre-embedded leveling steel plate adopts an L-shaped structure, each of the pre-stress crude steel bar wire anchor and the pre-embedded bolt penetrates through the ribbed slab and the pre-embedded leveling steel plate through a fastening screw, the long edge of the pre-embedded leveling steel plate is provided with base plates, the bottom of each of the base plates cooperates with the pre-embedded leveling steel plate, the obtained integral body is fixedly fastened through ribbed stiffeners, the top of the base plates is provided with a loading plate, the loading plate is detachably connected with the pre-embedded leveling steel plate through the base plates and carbon fiber bars, the number of the base plates is two, the number of the carbon fiber bars is two, and the upper surface of the loading plate is provided with a clip anchor device. The steel bar clip pre-stress tensioning anchor block has the advantages of strong bearing strength, greatly improved anchoring performance, repeated use due to detachable movement, high anchor back rate, enough pre-stress tension and wide application range.

Description

technical field [0001] The invention relates to an anchor block, in particular to a steel clip prestressed tension anchor block. Background technique [0002] The prestressed tension anchor block is suitable for construction projects such as roads and bridges. After the prestressed anchor block is locked and used, if it is reused or the facility is dismantled, the prestressed anchor block needs to be withdrawn. After the traditional prestressed anchor block is locked, it is difficult to remove the anchor due to the large friction force. The successful anchor removal rate is very low when using anchor removal equipment. Destructive anchor removal methods such as fire welding cutting, hacksaw cutting machine gunpowder are often used Blasting, etc., not only the cost of anchor withdrawal is high, but also the anchorage is basically damaged and cannot be used after anchor withdrawal. At the same time, carbon fiber reinforcement technology is becoming more and more perfect and w...
