Embodiment 1

[0030] Such as figure 2 As shown, the present invention discloses a connection sleeve, which includes a connection sleeve body and a through hole arranged in the connection sleeve body, the through hole is located at the center of the connection sleeve and along the length direction of the connection sleeve body According to the change of the inner diameter of the through hole, the through hole is divided into three sections, which are: tenon piece connection section 101, tenon-tenon wedge connection section 102 and steel bar connection section 103. The through holes of the mortise and tenon connecting section 101 are provided with equal diameters, and the through holes of the mortise and tenon wedge connecting section 102 are tapered holes; The through-hole connection of the reinforcing bar connecting section 103 is provided with an internal thread structure inside the reinforcing bar connecting section 103 . The connection sleeve is provided with a through hole, which is d...

Embodiment 2

[0032] in such as figure 2 On the basis of the shown connecting sleeve, the present invention also discloses a connecting tenon 3, such as image 3 to 5. The connecting mortise 3 is a cylindrical member, and both ends of the connecting mortise 3 are provided with connecting grooves 301, the groove depth of the connecting groove 301 is substantially equal to the length of the through hole of the mortise-and-tenon wedge connection section 102, and the connecting grooves 301 and The tenon and tenon parts 3 are arranged concentrically. Preferably, the groove depth of the connection groove 301 should be about 5mm greater than the length of the through hole of the mortise-tenon wedge connection section 102 . The concentric setting can effectively ensure that when the connecting wedge 4 is inserted into the connecting groove 301, the force on the connecting tenon 3 is even. Considering that the connecting tenon 3 is a circular component, in order to ensure uniform stress, in thi...

Embodiment 3

[0035] On the basis of the above-mentioned connecting sleeve and connecting tenon piece 3, the present invention also discloses a tenon-tenon wedge connection device. The device is mainly composed of a first connecting sleeve 1, a second connecting sleeve 2, a connecting tenon 3 and a connecting wedge 4, etc. The first connecting sleeve 1, the second connecting sleeve 2 and the connecting tenon 3 can be made of steel, preferably the first connecting sleeve 1, the second connecting sleeve 2 and the connecting tenon 3 are all selected from No. 45 steel material.

[0036]The length of the first connecting sleeve 1 is about three times its diameter. The first connection sleeve 1 comprises a first connection sleeve body, and a through hole arranged in the first connection sleeve body, the through hole is located at the center of the connection sleeve and arranged along the length direction of the connection sleeve body, which can effectively Ensure that the wall thickness of the ...

Abstract

The invention relates to the technical field of connecting construction of fabricated building concrete members, in particular to a connecting sleeve, a connecting tenon part and a tenon-mortise wedgeconnecting device. The connecting sleeve is internally provided with a through hole, and the through hole is formed in the length direction of the connecting sleeve; the through hole comprises a tenon part connecting section, a tenon-mortise wedge connecting section and a steel bar connecting section; and the through hole in the tenon part connecting section is formed in an equal-diameter mode, the through hole in the tenon-mortise wedge connecting section is a conical hole, the small-opening end of the conical hole is connected with the through hole in the tenon part connecting section, thelarge-opening end of the conical hole is connected with the through hole in the steel bar connecting section, and an inner threaded structure is arranged inside the steel bar connecting section. The connecting sleeve is novel in design and reasonable in structure, is used for the tenon-mortise wedge connecting device and is wide in application range; and tenon-mortise wedge connecting is adopted,and structural reliability is good.

Description

technical field [0001] The invention relates to the technical field of connection construction of prefabricated building concrete components, in particular to a connection sleeve, a connection tenon piece and a tenon-tenon wedge connection device. Background technique [0002] At present, the construction industry has become one of the pillar industries of the national economy. Our country has won the title of infrastructure madman in the world, but in terms of civil construction, our country is still a labor-intensive traditional industry dominated by cast-in-place construction. The on-site workers have high labor intensity and low work efficiency, and the energy consumption of product production High, noise, dust pollution to the environment, coupled with the shortage of labor in recent years, the traditional construction methods are no longer suitable for my country's national conditions. For this reason, vigorously developing productivity, reducing energy consumption, en...
