Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 , 2 As shown, the steel bar full grouting sleeve used for the prefabricated concrete strong connection of the present invention includes a grouting sleeve body 1 with a cavity inside, the two ends of the grouting sleeve body 1 are steel bar insertion sections with different apertures, one end It is the insertion section 4 of small-diameter steel bar, and the other end is the insertion section 3 of large-diameter steel bar. The length of the insertion section 3 of large-diameter steel bar is greater than the length of the insertion section 4 of small-diameter steel bar. The key function of the grouting sleeve of the present invention is that the two ends of the grouting sleeve body 1 will be used to connect the small-diameter steel bar 9 and the large-diameter steel bar 10 respectively, and the small-diameter steel bar will penetrate the variabl...

Abstract

The invention discloses a steel bar full-grouting sleeve for prefabricated concrete strong connection. The steel bar full-grouting sleeve comprises a grouting sleeve body with a cavity provided therein, two ends of the grouting sleeve are steel bar insert segments with different apertures to connect vertical steel bars with different diameters, and are connected through a variable diameter through hole, the variable diameter through hole is provided with a steel bar spacing plate, the inner wall of the cavity in the grouting sleeve body is provided with rectangular projection shear connectors, adjacent shear connectors form an annular shear slot in order to enhance the binding occlusion force between a grouting material and the grouting sleeve, two ends of the grouting sleeve body are respectively provided with a grouting hole and a pulp discharging hole, and one end or two ends of the grouting sleeve body is / are provided with a structure for installing one or two sealing gasket(s). The steel bar full-grouting sleeve can solve the connection problem of vertical steel bars with different diameters in the prefabricated concrete strong connection, and ensures effective force transfer of the vertical steel bars with different diameters.

Description

technical field [0001] The invention relates to a steel bar full grouting sleeve used for a prefabricated concrete strong connection. Background technique [0002] With the acceleration of my country's construction industrialization process, many provinces and cities have compiled technical regulations for prefabricated reinforced concrete structures suitable for local conditions. The Ministry of Housing and Urban-Rural Development also issued and implemented the industry standard "Prefabricated Concrete Structures" in 2014 This is of great significance to promote the development of housing industrialization technology. [0003] Guangdong Province also responded to the country's call and will soon implement the provincial standard "Technical Regulations for Prefabricated Concrete Building Structures", which is different from industry standards and introduces "strong connection" into the Guangdong Provincial Standard. "Strong connection" refers to the connection that when th...
