Embodiment Construction

[0043] Examples see figure 1 , 2 , the reinforcement anchoring device is formed by connecting an anchor plate 1 with the end of a ribbed steel bar 2, and the anchor plate is made of cast iron or ductile iron. The anchor plate 1 is in the shape of a head and shoulders, the insertion end of the shoulder 11 of the anchor plate is a plane, the head 12 of the anchor plate is nut-shaped or nut-shaped, and the center of the anchor plate is connected with the external thread 21 at the end of the ribbed steel bar. Internally threaded hole 13. The connection length between the end of the ribbed steel bar and the anchor plate is any value between 1.0d-3.0d, where d is the diameter of the steel bar.

[0044] see image 3 , 4 , 5, 6, 7, 8, the shape of the cross section of the anchor plate shoulder 11 is circular, oval, square, rectangular or polygonal. The anchor plate head 12 has a hexagonal, quadrangular, octagonal or other polygonal shape, which can be tightened with a screw nut f...

Abstract

The invention relates to a steel bar anchor device and relative method, which is formed by connecting anchor plate and the end part with rib steel bar. Wherein, the anchor plate is in head-shoulder integrated shape, while the insert end of shoulder is a plane and the head is in screw cap shape or nut shape. The center of anchor plate has an inner screw matching the external screw of said end part. The anchor plate can be classified into two kinds as full-anchor plate and part-anchor plate, according to the ratio between the area of bearing plate and the section area of steel bar, which can be used in different areas to reduce adhesive anchor length or fully eliminate the length. The invention can reduce 40-50% of anchor steel material, to improve the concrete irrigate quality, the constructing speed, reduce the cost and simplify the process.

Description

(1) Technical field: [0001] The invention relates to an anchoring device for anchoring steel bars and a construction method thereof. (two), background technology [0002] Steel bar anchoring is a basic technology encountered in various concrete structural projects such as industrial and civil buildings, long-span bridges, hydraulic structures, subways, tunnels, TV towers, nuclear power plants, etc. Every steel bar in a reinforced concrete project needs to be reliably anchored. Anchoring can exert its strength, and the anchoring of steel bars is a basic technology with a large amount and a wide range in concrete engineering. The traditional anchoring method of steel bars is to use the bonded anchorage length of 30-45 times the diameter of the steel bar to anchor the steel bar, or to use the bent steel bar and the steel bar with hook to reduce the bonded anchorage length to anchor. This traditional anchoring method adds a large amount of steel bars for anchoring, and causes t...
