Embodiment Construction

[0036] Such as Figure 1 to Figure 7 As shown, the full grouting sleeve for steel bar connection in this embodiment includes a first grouting sleeve 1 and a second grouting sleeve 2 on both sides, and an eccentric joint 3 connecting the two grouting sleeves, wherein the first grouting sleeve The first grouting sleeve 1 and the second grouting sleeve 2 are respectively provided with grouting holes, and the two sections of the grouting sleeves are connected through the eccentric joint 3, and the dislocated core-through steel bars are connected through the eccentric joint.

[0037] specifically,

[0038] The structure of the first grouting sleeve 1 is as follows, refer to figure 2 , a seamless steel pipe with a diameter of 20 cm is used for turning processing, and the length is more than 10 times the diameter, that is, 20 cm. An annular groove 11 is used to place the first sealing card 12. The first sealing card is a steel sheet with a thickness of about 1 mm, which is a stamp...

Abstract

The invention discloses an all-grouting sleeve for assembled building reinforcement connection and a grouting method, wherein the all-grouting sleeve comprises a first grouting sleeve and a second grouting sleeve on two sides, and an eccentric joint for connecting the two grouting sleeves; an annular groove, a first sealing clamping piece and a grouting hole are arranged at one end of the first grouting sleeve; an inner cone is arranged at the other end of the first grouting sleeve; a screw sleeve is arranged on the outer side, corresponding to the inner cone section, of the first grouting sleeve; the eccentric joint includes a middle disc, and a first frustum and a second frustum positioned on two sides of the middle disc and eccentrically arranged mutually; a through slurry discharge hole is formed in the center part of the first frustum; and the second grouting sleeve has the same structure as the first grouting sleeve, and is matched with the second frustum. Two frustums in the middle disc have an eccentric distance, so that the deviation problem in the lifting installation process of prefabricated components is solved, and the construction process becomes simple and feasible.

Description

technical field [0001] The invention relates to the technical field of connection construction of prefabricated concrete components of prefabricated concrete structures, in particular to a sleeve grouting connection structure of transverse steel bars in prefabricated concrete structures. Background technique [0002] At present, prefabricated concrete structures are constructed using industrial technology, and their main structural parts are prefabricated in factories. After arriving at the site, these prefabricated concrete components are installed and connected into a whole. This industrial production method greatly reduces the amount of wet work on the construction site. , significantly increased the construction speed, reduced environmental pollution and material consumption, and has become a new direction for the development of my country's construction industry. The steel bar connection of prefabricated concrete structures is the key to the structural safety. The steel ...
