Embodiment 1

[0048] A pre-embedded steel bar end anchor 1, such as figure 1 As shown, it is a cylindrical structure 11 with only one end open, the opening direction is parallel to the axis of symmetry of the cylindrical structure 11, the opening 13 of the cylindrical structure 11 is coaxial with the cylindrical structure 11, and the inner wall of the opening 13 is provided with a Threaded structure of reinforcement I;

[0049] The end face of the pre-embedded steel bar end anchor away from the open end extends radially to form an end cover 12;

[0050]The outer wall of the pre-embedded steel bar end anchor is provided with three annular protrusions 14 along the opening direction;

[0051] The outer wall of the pre-embedded steel bar end anchor is also provided with a plurality of strip-shaped protrusions 15 connecting all the annular protrusions 14 and the end caps 12 , and the strip-shaped protrusions 15 are distributed around the circumference of the pre-embedded steel bar end anchor 1 ...

Embodiment 2

[0058] A kit including cast-in rebar end anchors such as Figure 4 As shown, it includes the same pre-embedded steel bar end anchor 1 and fixing plate 6 as in embodiment 1;

[0059] Have a plurality of buried holes 61 on the fixed plate 6, the pre-embedded steel bar end anchor 1 is fixed on the buried hole of the fixed plate 6 by the plug 5, and the back side of the fixed plate is provided with a plurality of blind holes (threaded holes) that facilitate the insertion of the dismounting tool II. ), after completing the prefabrication of the concrete prefabricated part, insert the dismantling tool II into the blind hole to separate the fixing plate from the concrete prefabricated part;

Abstract

The invention discloses an embedded steel bar end anchor, a kit comprising the embedded steel bar end anchor and a connection construction method of the embedded steel bar end anchor. The embedded steel bar end anchor is of a cylindrical structure with only one end open, the opening direction is parallel to the symmetry axis of the cylindrical structure, and a threaded structure I used for connecting steel bars is arranged on the inner wall of an opening; the end faces, away from the open ends, of the embedded steel bar end anchors extend radially to form end covers; a plurality of annular protruding structures are arranged on the outer wall of the embedded steel bar end anchor in the opening direction; the embedded steel bar end anchor is embedded in the concrete prefabricated part, and an opening of the embedded steel bar end anchor is located on the edge of the prefabricated part and can communicate with the outside; the external member further comprises a fixing plate; and a plurality of buried holes are formed in the fixing plate, and the embedded steel bar end anchors are fixed to the buried holes of the fixing plate through plugs. The embedded steel bar end anchor is simplein structure, reliable in fixation, easy and convenient to operate, capable of saving time and labor and high in working efficiency; the bearing tension and shearing force are high; the device can berepeatedly used, is low in cost and has great application prospect.

Description

technical field [0001] The invention belongs to the technical field of building embedded parts, and relates to a pre-embedded steel bar end anchor, a kit including the same and a connection construction method thereof, in particular to a method which greatly facilitates the connection of steel bars and is compared with the existing welded steel bar connection. Embedded parts and their connection construction methods with more reasonable stress. Background technique [0002] With the development of modern industrial technology, building houses can be manufactured in batches and in sets like machine production. As long as the prefabricated building components are transported to the construction site for assembly, the construction on the construction site is simplified. Assembled architecture began to arouse people's interest in the beginning of the 20th century, and finally realized to the sixties. Britain, France, the Soviet Union and other countries first made attempts. B...
