Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding sleeves, in particular to an oblique-pull groove welding sleeve. Background Art
[0002] The main function of the welding sleeve is to connect and fix the steel bars and steel plates in the steel structure. It is also used as an embedded part in the prefabricated components of assembled buildings. It is fixed to the steel structure by welding. It is mainly used for connecting steel bars and steel plates. For example, one end is welded and the other end is threaded. The length can be customized according to the project requirements. The large chamfered end can be spot welded to the steel column to ensure the stability of the connection.
[0003] The utility model with announcement number CN217268058U discloses a weldable sleeve, including a welding plate, a sleeve, a connecting assembly and a steel bar. The sleeve is a through-hole structure and is fixedly connected to the welding plate. A groove is provided inside the sleeve, and the groove is opened along the length direction of the sleeve. A part of the connecting assembly is slidably connected to the groove, and the sliding direction is consistent with the depth direction of the groove. The other part of the connecting assembly passes through the sleeve toward the bottom of the groove and is slidably connected to the sleeve. The sliding directions of the two parts of the connecting assembly are consistent. The steel bar is inserted into the sleeve. The part of the steel bar inserted into the sleeve is provided with a slot. The slot is opened along the length direction of the steel bar and corresponds to the connecting assembly. The connecting assembly is plug-and-socket connected to the slot.
[0004] In the above technical solution, the reverse thread on the connecting assembly is snap-fitted with the external thread of the steel bar, which improves the firmness of the sleeve and the steel bar. The chamfer and tripod further strengthen the firmness of the sleeve and the welding plate. However, the welding sleeve does not have a diagonal structure, which is not convenient for strengthening the stability of the installation between the sleeve and the steel bar. The diagonal surface increases the stability of the guided installation. In addition, when the welding sleeve is combined with the steel bar, the outer wall friction is small, which is not convenient for stable installation. Utility Model Content
