The locking sleeve 3 is a pipe fitting with openings at both ends, the locking sleeve 3 is provided with an internal thread, the locking sleeve 3 is arranged on the locking threaded rod, and the locking sleeve 3 is configured to squeeze the steel bar 2 into the hook body. The extended self-locking sleeve 4 comprises a straight tube with an opening at least at one end, at least one anti-slip thread buckle is arranged inside the straight tube, and the end of the straight tube away from the opening is fixedly connected to the locking threaded rod. The locking head 5 includes a self-locking column and a fixing part. The self-locking column includes a straight rod and a locking tooth. At least one locking tooth is fixed on the straight rod. The locking tooth is adapted to the anti-stripping buckle. When the self-locking column is inserted into the straight tube, the anti-stripping buckle only allows the locking tooth to move in one direction. The fixing part is fixed to the end of the self-locking column. The fixing part is configured to fix the insulation board to the self-locking column.

[0022] In some examples, the front part of the steel bar locking hook 1 is a hook body, and the rear part is a locking threaded rod. The steel bar locking hook 1 is formed by integral casting of steel or cutting of steel. When the hook body is hooked onto the corresponding steel bar 2 inside the steel bar frame, the locking sleeve 3 is screwed onto the locking threaded rod. At this time, the locking sleeve 3 can press the steel bar 2 with the hook body to achieve the fixation of the hook body and the steel bar 2.

[0023] The extended self-locking sleeve 4 can be a pipe with an open end. A plurality of anti-slip threads are arranged in sequence in the extended self-locking sleeve 4 along its extension direction. The extended self-locking sleeve 4 is fixedly connected to the locking threaded rod, and a plugging piece, such as a plug, is used to plug the opening of the extended self-locking sleeve 4. Then, the steel frame is poured with concrete to form a wall. At this time, the open end of the extended self-locking sleeve 4 should be flush with the wall surface or slightly protrude from the wall surface, for example, by 1 to 5 mm.

[0024] The blocking piece at one open end of the extended self-locking sleeve 4 is removed, and the self-locking column of the lock head 5 penetrates the insulation board, that is, the self-locking column passes through the insulation board, and the fixing piece fits the surface of the insulation board. Then the self-locking column extending to the outside of the insulation board is inserted into the extended self-locking sleeve 4, and the locking teeth on the self-locking column and the anti-stripping thread buckle are buckled, so that the insulation board is closely attached to the wall and is not easy to fall off.

[0025] Or the length of the open end of the extended self-locking sleeve 4 beyond the wall surface is greater than or equal to the thickness of the insulation board. When the insulation board is pressed against the wall, the extended self-locking sleeve 4 passes through the insulation board, and then the lock head 5 is inserted into the extended self-locking sleeve 4, and the fixing part is pressed to the surface of the insulation board. Example 2

[0026] like Figure 5 As shown, on the basis of Example 1, the hook body of this embodiment includes a cylindrical rod, and the cylindrical rod is provided with a through groove, and the extension direction of the through groove is perpendicular to the extension direction of the cylindrical rod. The cylindrical rod is provided with an external thread, and the external thread extends from one end of the cylindrical rod to the through groove, and the distance from the external thread to the bottom surface of the through groove is less than the diameter of the steel bar 2. The cylindrical rod is coaxially fixedly connected with the locking threaded rod, and the external thread on the cylindrical rod is adapted to the external thread on the locking threaded rod, so that the locking sleeve 3 smoothly transitions from the locking threaded rod to the hook body.

[0027] The hook body can be processed by a rod, and the rod is provided with an external thread from one end, and a through groove can be provided at the other end of the rod, and the through groove is perpendicular to the rod. Of course, in order to prevent the steel bar 2 from falling off from the through groove, the inside of the through groove can be a cylindrical curved surface, and the opening of the through groove forms a hook shape with the inside of the through groove. When the steel bar 2 is set in the through groove, the locking sleeve 3 is screwed onto the external thread of the rod until the locking sleeve 3 presses the steel bar 2 to fit the inner wall of the through groove. In addition, in order to prevent the steel bar 2 from falling off, the locking sleeve 3 can be screwed to a position that fully or partially covers the opening of the through groove, so that the steel bar 2 cannot fall off from the opening of the through groove, that is, the diameter of the steel bar 2 is larger than the opening width left after the locking sleeve 3 covers it. Example 3

[0028] Based on Example 2, a blind hole is provided at one end of the locking threaded rod away from the cylindrical rod, and an internal thread is provided in the blind hole.

[0030] The locking tooth is a conical structure adapted to the anti-stripping thread buckle, and the locking tooth includes a transition surface and a locking surface, the transition surface is a reducer structure, the small diameter end of the transition surface is smoothly transitionally connected to the side wall of the straight rod, the locking surface is a vertical ring, the outer ring of the locking surface is fixedly connected to the large diameter end of the transition surface, and the inner ring of the locking surface is fixedly connected to the side wall of the straight rod.

[0031] The extended self-locking sleeve 4 has a self-locking structure. In the current technology, reliable, economical and simple self-locking structures are generally made of hard plastic materials, such as PVC, PP, etc. The extended self-locking sleeve 4 can be integrally cast and formed. It has different strength requirements from the steel bar locking hook 1 and only requires higher strength in the tensile direction. Therefore, in this application, the steel bar locking hook 1 and the extended self-locking sleeve 4 are separately arranged. Example 4

[0032] Based on the above embodiment, the fixing member is a plate or at least three rods arranged in a circumference. The fixing member further includes a buckle, which is a conical structure, and the buckle is fixed to the end of the rod away from the self-locking column, and the buckle is configured to be pressed into the insulation board to fix the insulation board and the rod.

[0033] The fixing part can be a plate, such as a circular plate, and a buckle is provided on one side of the plate close to the self-locking column. The buckle can be a raised cone. When the fixing part presses the insulation wall, the raised cone will be pressed into the insulation wall and the insulation wall will be fixed.
