Embodiment 1

[0036] Embodiment 1: as Figure 1 to Figure 6As shown, the present invention provides a connection device for materials with different diameters, the large diameter material is a hot-rolled ribbed steel bar 4, the small diameter material is a prestressed concrete steel bar 5, and the connection device is used to connect the hot-rolled ribbed steel bar 4 It is connected with the prestressed concrete steel rod 5, and also meets the tension requirement of the prestressed concrete steel rod 5. The connecting device includes a connecting sleeve 300, a locking piece 200 and a diameter-reducing sleeve 100. The connecting sleeve 300 has an inner hole penetrating axially, one end of which is an equal-diameter end 301 with a constant inner diameter, and the other end is an end with a reduced inner diameter. Reduced-diameter end 302, the inner diameter of the equal-diameter end 301 is greater than the outer diameter of the hot-rolled ribbed steel bar 4 to be connected, and the inner hole...

Embodiment 2

[0039] Example 2, such as Figure 7 and Figure 8 As shown, the others are the same as in Embodiment 1, the difference is that the locking piece 200 is formed by opening a number of deformation grooves 204 along the axis on the inner wall of the conical cylinder 205, and the deformation grooves 204 are not seriously dug through in the radial direction. , so the locking piece 200 is still a tapered cylinder 205 as a whole, and the dug out part provides space for the radial compression deformation of the locking piece 200 .

[0040] It should be noted that the inner wall of the connecting sleeve 300 of the present invention can be a plane or a rough surface composed of a large number of protrusions or grooves, and the specific shape is not limited. When the connecting sleeve 300 is deformed, the rough surface can generate enough static friction to The connecting sleeve 300 is connected with the hot-rolled ribbed steel bar 4 together.

[0041] It should be noted that the materi...

Embodiment 3

[0042] Embodiment 3, other parts are identical with embodiment 1, as figure 2 , 5 As shown, the difference is that: the inner wall of the equal-diameter end 301 of the connecting sleeve 300 is processed into internal threads 303 or several annular grooves; the inner wall of the integral tapered cylinder 205 is processed into internal threads 203 or several annular grooves, The outer wall of the tapered cylinder 205 is provided with a taper matching the reduced-diameter end 302 of the connecting sleeve 300 , and the center of the tapered cylinder 205 is provided with a connecting shaft hole 206 whose diameter is slightly larger than the outer diameter of the prestressed concrete steel rod 5 . Through the internal thread setting, the bite ability is increased, the connection strength is improved, and the driving force for driving the reducing sleeve is reduced.

[0043] In use, when the reducing sleeve 100 passes through the equal-diameter end 301, the connecting sleeve 300 is...

Abstract

The invention discloses a connecting method and a connecting device for materials with different diameters. The connecting device comprises a connecting sleeve, a locking sheet and a reducing sleeve, wherein two ends of the connecting sleeve are respectively an equal-diameter end and a reducing end which are respectively used for connecting materials with large and small diameters, and an inner hole of the reducing end is gradually reduced from the middle to the end part; the locking sheet is arranged between the small-diameter material and the hole wall of the conical inner hole; the outer diameter of the connecting sleeve is larger than the inner diameter of the small-inner-diameter end of the reducing sleeve and smaller than the inner diameter of the large-inner-diameter end of the locking sleeve; and the reducing sleeve is used for being arranged on the connecting sleeve in a sleeving mode under the action of an external force and penetrating through the connecting sleeve in the axial direction, so that the connecting sleeve and / or the locking sheet generate radial plastic deformation, and the large-diameter material and the small-diameter material are connected together through the connecting sleeve. The problem that in the prior art, materials with different diameters cannot be connected in a high-strength mode is solved, and the device is simple in structure, convenient to use, good in stability, high in practicability and suitable for large-area application and popularization.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to a construction material connection technology, in particular to a connection method and a connection device for materials with different diameters, which are used for the connection between steel materials or between steel materials and other materials. Background technique [0002] Currently used in building concrete structures, most of the reinforcement materials are connected by lap joints and straight threaded sleeves. The connection strength of lap joints is insufficient. When using threaded sleeves, if the operator fails to align the sleeves accurately For the middle line of the steel bar, if the thread is not completely aligned, the wrench is used to screw it, which will easily cause the steel bar to not be screwed in place, thereby reducing the connection quality between the steel bar and the straight thread sleeve. Therefore, in fact, there are many technical defects...
