Description

Technical Field

[0001] The utility model relates to the field of steel bar butt jointing, in particular to a steel bar butt jointing auxiliary device. Background Art

[0002] Prefabricated rebar components typically utilize mechanical connection methods to connect the upper and lower segments. Currently, the most popular rebar connectors include straight thread sleeves, straight extrusion sleeves, and tapered extrusion sleeves. Straight thread sleeves are widely used due to their low cost and high installation efficiency. Straight thread sleeve connections require two conditions: high-precision rebar positioning and matching of the rebar threads. They are generally suitable for loose-tying single rebar. The use of straight threads in prefabricated rebar components typically requires a pre-matching process. This process is performed in a short-line or long-line matching method, which is then removed from the pre-connected sleeves and installed on-site. The short-line matching method utilizes two prefabrication stations. Before the lower segment is fabricated, the upper segment must be hoisted to the matching station to reserve space for prefabrication. This process is cumbersome, with poor positioning accuracy and low construction efficiency. The long-line matching method typically utilizes multiple prefabrication stations, which occupies a large construction site and results in high overall costs. Therefore, a rebar connection assistance device has been proposed to address these issues. Utility Model Content

[0024] like Figure 1-5As shown, a steel bar joint auxiliary device includes a positioning sleeve 4, a matching sleeve 3, a lock nut 6 and a support frame 1. The lock nut 6 is detachably mounted on the opposite ends of the positioning sleeve 4 and the matching sleeve 3. The positioning sleeve 4 and the matching sleeve 3 can be connected by the lock nut 6. The separated ends of the positioning sleeve 4 and the matching sleeve 3 are both provided with wire holes for connecting steel wire heads. The threads of the two wire holes are connected, wherein the positioning sleeve 4 is used to collect information about the steel wire head of the previous section, and the matching sleeve 3 is used to transmit the information to the steel wire head of the next section. The support frame 1 is composed of a base 101 and a vertical plate 102 erected in the middle of the base 101. The vertical plate 102 is provided with a mounting hole 2 for the matching sleeve 3 to pass through.

[0025] A fastening assembly for locking the matching sleeve 3 is provided on the plate 102 .

[0026] When in use, the opposite ends of the positioning sleeve 4 and the matching sleeve 3 are connected by the lock nut 6, and then the thread hole of the positioning sleeve 4 is put onto the steel wire head of the previous section to complete the information collection of the steel wire head of the previous section, and then the support frame 1 is put on the outside of the matching sleeve 3 through the mounting hole 2 and fastened with the fastening assembly. After the fastening is completed, the positioning sleeve 4 is removed, and then the support frame 1 and the matching sleeve 3 are positioned and installed on the tire frame for installing the next section of steel bars. At this time, the information of the steel wire head of the previous section is left and transmitted to the tire frame, and the indirect matching of the steel bars can be completed by directly screwing the steel wire head of the next section into the thread hole of the matching sleeve 3, thereby ensuring the wire matching accuracy between the steel bars. In this embodiment, the thread position information of the steel wire head is effectively transmitted through the positioning sleeve 4 and the matching sleeve 3, thereby solving the problem of thread matching.

[0027] It should be noted that the support frame 1 can be fixed to the steel frame by means of steel wire binding. In addition, when fixing the support frame 1 and the matching sleeve 3, it is necessary to ensure that the support frame 1 is perpendicular to the frame to avoid angle deviation and the problem of information transmission deviation in the matching sleeve 3 when it is installed on the frame.

[0028] In the preferred embodiment, the positioning sleeve 4 and the matching sleeve 3 are detachably arranged in the lock nut 6 through threaded installation, and matching docking steps 5 are provided at the opposite ends of the two, and matching spiral wires are provided on the outside. The setting of the docking steps 5 facilitates to improve the locking strength of the lock nut 6 on the positioning sleeve 4 and the matching sleeve 3, and at the same time ensures that when the positioning sleeve 4 and the matching sleeve 3 are connected, the threads of the thread holes of the two are connected to avoid information transmission errors. When the lock nut 6 connects the positioning sleeve 4 and the matching sleeve 3, the central axes of the two are connected, and at the same time, they are connected through the threads of the thread holes of the two, thereby achieving the effect of transmitting the thread position information.

[0029] It should be noted that when the support frame 1 is mounted on the outside of the matching sleeve 3 , the spiral thread of the matching sleeve 3 outside the mounting hole 2 meets the requirement that the lock nut 6 rotates out of the positioning sleeve 4 .

[0030] In the preferred embodiment, the fastening assembly includes a fastening screw hole 7 that passes through the top of the mounting hole 2, and a fastening screw 8 is threaded in the fastening screw hole 7 for locking the matching sleeve 3. The bottom end of the fastening screw 8 is in contact with the matching sleeve 3 to achieve the locking effect.

[0031] A rubber pad is fixed to the bottom end of the fastening screw 8 to protect the exterior of the matching sleeve 3 .

[0032] In a preferred embodiment, a circular bubble level 9 for determining the horizontality of the support frame 1 is provided on the base 101 of the support frame 1 .

[0033] This device replaces the traditional straight-thread connection method, which requires long or short matching wires. It achieves in-situ rebar production, saving workshop rebar processing space, significantly improving construction efficiency and quality, ensuring inherent safety, and increasing on-site rebar construction efficiency by 50%. Compared to the large space required for short or long matching wires, this technology can save 50%-80% of the rebar prefabrication site and improve in-plant production efficiency by 30%.

[0034] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
