Embodiment Construction

[0028] Attached below figure 1 ~ attached Figure 6 The preparation method of the present invention is further described in detail:

[0029] The tension end anchor 7 includes: a steel plate with grooves 1, the two ends of the steel plate with grooves 1 are vertically welded to one side of the first steel plate with holes 2 and the second steel plate with holes 3, and the steel plate 4 is parallel to the grooved steel plate 4. The grooved steel plate 1 is placed and welded on the other side with the first steel plate with holes 2 and the second steel plate with holes 3; the steel plate with grooves 1, the first steel plate with holes 2, the second steel plate with holes 3, The steel plate 4 forms the side of the cuboid, and the additional bead 5 of the tension end anchor is placed in the side of the cuboid parallel to the grooved steel plate 1 to form the tension end anchor 7 .

[0030] The production method of the steel plate with grooves is the same as that of ZL 2005200076...

Abstract

The invention relates to a prestress carbon fiber sheet reinforcing ground tackle and a construction technology for reinforcing concrete structure thereof, belonging to the field of reinforcing bridges and industrial architectures. The two ends of a steel plate (1) with a groove are respectively and vertically welded with one side of a first steel plate (2) with a hole and one side of a second steel plate (3) with a hole, a steel plate (4) is parallel to and arranged in the steel plate (1) with the groove, and the steel plate (4) is welded with the other side of the first steel plate (2) with the hole and the other side of the second steel plate (3) with the hole, the steel plate (1) with the groove, the first steel plate (2) with the hole, the second steel plate (3) with the hole and the steel plate (4) form the sides of a cuboid, and an additional layering (5) of a stretching end ground tackle is parallel to the steel plate (1) with the groove, and is placed in the sides of the cuboid to form the stretching end ground tackle (7). The ground tackle can ensure the stretching stress of the carbon fiber sheet reaches over 65% of the limiting stress thereof, the additional layering (5) of the stretching end can ensure the ground tackle to traverse and not to tilt. The reinforcing method of the invention does not need large mechanical equipment, and can improve the stretching efficiency of the carbon fiber sheet.

Description

technical field [0001] The invention relates to a prestressed fiber cloth reinforced anchorage and a construction technology for reinforced concrete structures, belonging to the field of bridge and industrial building reinforcement. Background technique [0002] In recent years, my country's civil engineering construction has made great progress. Among the existing nearly ten billion square meters of high-rise buildings, exhibition centers, industrial plants, high-rise residences, railways, highways, bridges, tunnels, ports and large-scale water conservancy projects, Concrete structures occupy a large proportion. New structures, new materials, new technologies and new processes have been researched, developed and applied. Many concrete structures or components have good durability under normal environmental conditions, but due to aging, unreasonable design, improper construction management, changes in use functions, environmental corrosion and man-made damage, the structural...
