Problems solved by technology

The reinforcement sleeve used in the traditional mechanical connection method requires a certain horizontal displacement of the prefabricated components to realize the connection between the horizontal reinforcement during the construction process, which makes the operation space in the horizontal direction small or even no horizontal operation space where the connection of transverse reinforcement is restricted

Embodiment Construction

[0025] In conjunction with the accompanying drawings and implementation cases, further illustrate the separate cold extruded steel bar sleeve and its installation method of the present invention;

[0026] The technical scheme that the present invention specifically adopts is: as figure 1 Shown, a kind of separated cold extruded steel bar sleeve, its composition comprises by sleeve upper half 3 transverse steel bar sleeve lower half 4;

[0027] Such as figure 2 and image 3 As shown, there are five bolt holes 9 on the upper half of the sleeve 3, among which three bolt holes 9 are located in the middle of the upper half of the sleeve 3, and there are one bolt at both ends of the upper half of the sleeve 3 hole 9;

[0028] Such as Figure 4 and Figure 5 As shown, the lower half of the sleeve 4 is provided with five fixing nuts 8 corresponding to the positions of the bolt holes of the upper half of the sleeve 3;

[0029] The joints of the horizontal reinforcement are proce...

Abstract

A separated cold extruding steel bar sleeve comprises a sleeve upper half part and a sleeve lower half part. The sleeve upper half part is provided with five bolt holes, and the sleeve lower half part is provided with five fixing nuts corresponding to the bolt holes of the sleeve upper half part in position. A transverse steel bar connector is machined to be in a stepped shape. Transverse steel bars comprise a bottom steel bar and a top steel bar. The bottom steel bar is provided with three bolt holes corresponding to the bolt holes of the sleeve upper half part in position, and the top steel bar is provided with three bolt holes corresponding to the bolt holes of the sleeve upper half part in position. The sleeve upper half part, the sleeve lower half part, the bottom steel bar and the top steel bar are mounted by screwing bolts into the bolt holes, and a bolt connecting section and an extruding section are finally formed. By adoption of the separated cold extruding steel bar sleeve, construction operation is easy and convenient, connection of the transverse steel bars is achieved through mechanical interlocking fastening force of the extrusion-deformed steel sleeve and the ribbed steel bars, and transverse screws.

Description

technical field [0001] The invention belongs to the technical field of prefabricated steel bar connection, in particular to a separate cold extruded steel bar sleeve. Background technique [0002] There are many ways to connect prefabricated components, but it is mainly through the connection of steel bars in prefabricated components to realize the assembly connection between components. The overlapping of steel bars obviously cannot meet the needs of precast component assembly. Usually, the overlapping length of steel bars is 35d. At this time, the reserved gap between components is too large, and the cast-in-place part is greatly increased. The factory production of precast concrete components is meaningless. For the welded connection of steel bars, the welding process also requires a large manual operation gap between the components, and the welding time is long, and the support of the components is very difficult, and the firmness of the joint depends largely on the firm...
