[0002] Basically, concrete is arranged inside a steel member in a steel-concrete structure. To improve the strength of the structure, steel bars are also inserted inside the steel member. Usually, rib plates are arranged on the inner side of the steel member, and through holes are formed in the rib plates to facilitate the passing of the steel bars. The size of the through holes formed in the rib plates is larger than the size of the steel bars. In some steel-concrete structures, it is required that the steel bars be coaxial with the center of the through holes after passing through the through holes. However, there is no solution in the prior art for realizing the positioning of steel bar perforation. Moreover, the number of steel bar perforation positioning devices used is large, and their cost is also an important factor to be considered in the design. Therefore, there is an urgent need to provide a new solution that meets the low-cost requirements. Summary of the Utility Model

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Referring to Figure 1 , the present utility model provides a positioning device for steel bar perforation, which can realize the rapid positioning of steel bars and solve the problem that there is no suitable positioning scheme for steel bar perforation in the prior art. The installation sleeve and the positioning sleeve of the present utility model have the ability of elastic deformation through the arranged openings. The installation sleeve can be nested and installed in the through hole of the steel bar through deformation, realizing the fixation of the positioning device; the positioning sleeve can clamp the passing steel bar through deformation, thereby realizing the positioning of the steel bar. The structure is simple and the operation is convenient. The structure of the positioning device for steel bar perforation of the present utility model will be described below in conjunction with the accompanying drawings.

[0029] Referring to Figure 1 , a three-dimensional structure schematic view of the positioning device for steel bar perforation of the present utility model is shown. Referring to Figure 2 , a top view of the positioning sleeve of the positioning device for steel bar perforation of the present utility model facing upwards is shown. The positioning device for steel bar perforation of the present utility model will be described below in conjunction with Figure 1 and Figure 2 .

[0030] As Figure 1 and Figure 2 shown, the positioning device for steel bar perforation of the present utility model includes an installation sleeve 21 and a positioning sleeve 22. A first opening 211 communicating inside and outside is provided on the side of the installation sleeve 21, and the installation sleeve 21 can undergo elastic deformation through the first opening 211; the positioning sleeve 22 is connected to one end face of the installation sleeve 21, and a second opening 221 communicating inside and outside is provided at the corresponding first opening 211. The inner diameter of the positioning sleeve 22 is adapted to the outer diameter of the steel bar for positioning the steel bar.

[0031] During use, the installation sleeve 21 can be nested in the through hole of the steel bar to be installed. During installation, the installation sleeve 21 can undergo deformation through the first opening 211 and then be embedded into the through hole. The size of the installation sleeve 21 is adapted to the size of the through hole of the steel bar to be installed; then the steel bar is passed through the inside of the installation sleeve 21 and the positioning sleeve 22, and then the positioning sleeve 22 can clamp the steel bar, realizing the positioning of the steel bar.

[0032] In a specific implementation manner of the present utility model, as Figure 1 andFigure 2 As shown, the center of the positioning ferrule 22 is aligned with the center of the installation ferrule 21. The center of the positioning ferrule 22 is the center of the circle formed by the inner side surfaces of the positioning ferrule 22, and it is located at the same point as the center of the circle formed by the inner side surfaces of the installation ferrule 21. The concentric setting of the two can achieve the positioning function of the steel bar.

[0033] In a specific embodiment of the present invention, as Figure 1 and Figure 2 shown, the side of the installation ferrule 21 is provided with a plurality of notches 212 extending inward.

[0034] The notches 212 extend from the outside to the inside of the installation ferrule 21, but the notches 212 do not communicate with the inside of the installation ferrule 21. The setting of the notches 212 can reduce the overall stiffness of the installation ferrule 21, making the installation ferrule 21 easy to deform, so as to be conveniently nested in the through hole of the installed steel bar.

[0035] Preferably, there are three notches 212, which are evenly distributed on the outside of the installation ferrule 21.

[0036] In a specific embodiment of the present invention, as Figure 1 and Figure 2 shown, at least one end face of the installation ferrule 21 is provided with manipulation holes 213 located on both sides of the first opening 211.

[0037] The manipulation holes 213 are used to connect operation tools, such as pliers, etc. Insert the positioning rod on the operation tool into the manipulation holes 213, and then hold the operation tool tightly to compress the first opening 211, so that the installation ferrule 21 deforms, reducing the outer diameter of the installation ferrule 21, and then enabling the installation ferrule 21 to be embedded in the through hole of the installed steel bar.

[0038] Preferably, the manipulation holes 213 are circular holes.

[0039] In a preferred embodiment, the manipulation holes 213 can penetrate through the opposite two end faces of the installation ferrule 21.

[0040] In a specific embodiment of the present invention, as Figure 1 and Figure 3 shown, the middle part of the outer side surface of the installation ferrule 21 is recessed inward to form an inner concave surface 214, and the edge of the outer side surface of the installation ferrule 21 near the end face forms a clamping edge 215.

[0041] The size of the inner concave surface 214 is adapted to the size of the hole wall of the through hole of the installed steel bar. When the installation ferrule 21 is embedded in the through hole, the inner concave surface 214 is attached to the hole wall of the through hole, and the clamping edge 215 is blocked on both sides of the through hole and is attached to the structure at the through hole.

[0042] Furthermore, to facilitate the installation of the ferrule 21 into the through-hole, the side surface of the ferrule 21 away from the clamping edge 215 of the positioning ferrule is an inclined surface, which is connected to the corresponding end surface of the ferrule 21.

[0043] In a specific embodiment of the present invention, as Figure 2 shown, a deformation groove 222 is provided on the side of the positioning ferrule 22 opposite to the second opening 221. The provision of the deformation groove 222 enables the positioning ferrule 22 to have a certain deformation ability, so that the positioning ferrule 22 can tightly clamp the corresponding steel bar to achieve the positioning of the steel bar.

[0044] In a specific embodiment of the present invention, as Figures 1 to 3 shown, the ferrule 21 and the positioning ferrule 22 are of an integrally formed structure.

[0045] The end surface of the ferrule 21 and the end surface of the positioning ferrule 22 are connected and fixed by a connecting block 23. The provision of the connecting block 23 leaves a gap between the corresponding end surfaces of the positioning ferrule 22 and the ferrule 21. The provision of this gap enables the positioning ferrule 22 and the ferrule 21 to deform relatively independently of each other, that is, the deformations of the positioning ferrule 22 and the ferrule 21 do not interfere with each other.

[0046] Furthermore, the inner arc surface of the positioning ferrule 22 is closer to the inner side of the ferrule 21 than the inner side surface of the ferrule 21.

[0047] Preferably, both the positioning ferrule 22 and the ferrule 21 are of a cylindrical structure, and openings communicating the inside and outside are provided on the side. The materials of the positioning ferrule 22 and the ferrule 21 are preferably selected as spring steel, which has a certain elastic deformation ability and also has a certain stiffness.

[0048] The following describes the usage process of the positioning device for steel bar perforation of the present invention.

[0049] As Figures 4 to 7As shown in the figure, through holes are provided on the sheet material 10 corresponding to the steel bars 11. Before the steel bars 11 pass through the through holes, first nest the installation sleeve 21 of the positioning device for perforating steel bars of the present utility model in the through holes. The outer diameter of the installation sleeve 21 can be reduced by using an operating tool in cooperation with the control hole 213 on the installation sleeve 21. When the installation sleeve 21 is inserted into the through hole and the connection between the operating tool and the installation sleeve 21 is released, the installation sleeve 21 returns to its deformed state and is nested in the through hole. The concave surface 214 of the installation sleeve 21 is in contact with the hole wall of the through hole, and the clamping edge 215 is in contact with the corresponding parts of the two side surfaces of the sheet material 10. After setting the installation sleeve 21, pass the steel bars 11 through the inside of the installation sleeve 21 and the inside of the positioning sleeve 22. The positioning sleeve 22 clamps the steel bars 11, and the positioning sleeve 22 realizes the positioning of the steel bars 11.
