Problems solved by technology

[0003] In the construction method of the patent application number 02128047.8 applied by the inventor, the high-strength composite material is fixed at both ends and the construction method of transverse tension and anchorage in the middle is used. prestressed reinforcement, but in some special cases this method has deficiencies
For example, this method cannot be used when the engineering structure does not need to be prestressed; for example, when some engineering structures have special shapes or are restricted by the use environment, it is not convenient to use this method; etc.

Embodiment Construction

[0021] Below in conjunction with embodiment, further illustrate the present invention.

[0022] Such as image 3 As shown, in this embodiment, a reinforced concrete beam with a length of 3.40 meters, a height of 0.32 meters and a width of 0.16 meters is used as the test beam and the comparison beam. The lower corrugated tooth plate 1 of the corrugated tooth fixture anchor is pre-embedded in the test beam, and four corrugated tooth fixture anchors are shared, two of which are located at the two ends of the beam, and the other two are located at the two third points of the beam. A carbon fiber cloth 7 with a thickness of 3×0.111 mm and a width of 100 mm was pasted on the bottom of the test beam, and anchored with four corrugated tooth clamps at the bottom of the beam. In addition, a 3×0.111 mm thick carbon fiber cloth is also pasted on the bottom of the contrast beam, but the wave-tooth clamp is not used for anchoring. In order to facilitate various construction operations, wh...

Abstract

The invention is a constructing method for stretch-draw anchoring of a kind of high intensity compound material without prestress, which belongs to project structure reinforcement field. The invention anchors the high intensity compound material onto he reinforced structure one-way in order, it solves the problem of fail anchoring of compound material, it also displays the performance of high intensity of compound material, upgrades the bearing ability of the material, enlarges its lifespan. The method is flexible, convenient, economic, and reliable.

Description

1. Technical field [0001] The invention belongs to the technical field of high-strength composite materials reinforcing or reinforcing engineering structures, in particular to a construction method for high-strength composite materials reinforcing or reinforcing engineering structures without prestress. 2. Background technology [0002] High-strength composite materials (such as carbon fiber reinforced plastics, polymer fiber reinforced plastics, glass fiber reinforced plastics, etc.) have the characteristics of light weight, high strength, fatigue resistance, and corrosion resistance. , wood structure, concrete structure, etc.] ideal material. In practical engineering, carbon fiber cloth has been used to reinforce reinforced concrete structures. For example, the patent application number is 99105829.1 "Method for Reinforcing and Strengthening Concrete Buildings", which adopts carbon fiber cloth bonding method to strengthen reinforced concrete. Although this method improves...
