Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] like figure 1 , 2 As shown, a GFRP full grouting sleeve includes a sleeve main body 10 and a grouting port 11 and a grout outlet 12 respectively disposed on both sides of the sleeve main body 10. The sleeve main body 10 is made of glass fiber reinforced composite material (GFRP ) made of seamless pipe body. The end of the sleeve body 10 provided with the grouting port 12 is the insertion end of the pre-embedded steel bar 20A,...

Abstract

The invention relates to a GFRP (glass fiber reinforced plastic) full-grouting sleeve, comprising a sleeve body, and a grout inlet and a grout outlet that are arranged in two sides of the sleeve body; the sleeve body is a seamless tube produced with glass fiber reinforced plastic composite; each of the grout outlet and grout inlet of the sleeve body is provided with a self-closing valve. The glass fiber reinforced plastic composite is used to produce the sleeve body of the full-grouting sleeve, and the sleeve body has the advantages of light weight, high strength, good corrosion resistance, good sealing performance, reliable performance, zero shielding on electromagnetic wave and the like; the compactness of grout in the sleeve can be detected effectively by using electromagnetic wave detection technology, and workers are allowed to accurately judge the grouting quality of the sleeve grout; a reliable connection method is provided for reinforcement connection of prefabricated concrete structural members, and the GRFRP full-grouting sleeve is widely applicable to prefabricated concrete structures and has a promising engineering application prospect.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete components, in particular to a GFRP full grouting sleeve. Background technique [0002] At present, my country is in the stage of rapid development of construction industrialization. Vigorously promoting the prefabricated structure is the main direction of the modernization development of my country's construction industry, and it is also an effective way to realize the development of green buildings and construction industrialization. [0003] The most commonly used connection of steel bars in prefabricated concrete components is grouting sleeve connection and grout anchor lap. The components are transported to the site for construction and installation, and then the steel bars are inserted into the reserved holes of the grouting sleeve, and finally the grouting material is injected into the grouting sleeve to fix the steel bars at both ends together. For the grouting sleeve conne...
