[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 As shown, the utility model is a new type of reusable steel stirrup, including an upper and lower supporting structure and a suspension rod 2 structure. The upper and lower supporting structure includes two gate-shaped brackets 7, which are located at the bottom of the upper and lower supporting structure. A horizontal bracket 5 is arranged between the two gate-shaped brackets 7, and the horizontal bracket 5 is arranged along the horizontal plane. The two ends of the horizontal bracket 5 are fixedly connected to the gate-shaped bracket 7. Each gate-shaped bracket 7 is provided with an oblique bracket 4 at both ends of the top, and the top of the oblique bracket 4 at both ends of the same gate-shaped bracket 7 is inclined toward the center, and the four oblique brackets 4 are in the shape of a quadrangular pyramid. The tops of the four oblique brackets 4 extend out of the rods to fix the steel casing 3. The top of the upper and lower supporting structure is arranged with the suspension rod 2, and the top of the suspension rod 2 is rotatably provided with a rotating handle 1. The top of the suspension rod 2 is provided with an external thread, and the steel casing 3 is provided with a corresponding internal thread. The suspension rod 2 and the steel casing 3 are detachably threadedly connected by the external thread and the internal thread. A hook 6 is provided at the bottom end of the hanger 2, and a template 10 is provided on the upper and lower supporting structures and the bottom of the hanger 2. The template 10 is in contact with the bottom surfaces of the two gate-shaped brackets 7. A layer of concrete 9 is placed above the template 10, and a layer of steel mesh 8 is provided inside the concrete 9. The steel mesh 8 can support the hook 6.

[0028] Among them, the steel stirrup must have sufficient strength and rigidity to ensure that the stirrup is not crushed during use. The gate-shaped bracket 7 and the horizontal bracket 5 in the lower support structure are fixed by welding; the oblique bracket 4 in the upper support structure is welded and fixed to the horizontal bracket 5 of the lower support structure, and the steel casing 3 is welded and fixed on the top of the quadrangular pyramid oblique bracket 4, so that the upper and lower support structures are connected as a whole. It is necessary to calculate the height of the gate-shaped bracket 7 and the spacing of the hook 6 according to the design thickness of the cast-in-place concrete 9 floor slab and the thickness of the protective layer of the steel mesh 8 to adapt to different construction requirements; the design requires that different types of stirrups be evenly arranged on floors of different thicknesses. Adjust the stirrup rotating handle 1 so that the hook 6 rises to the designed position, and then place the steel mesh on the hook 6 at the lower end of the stirrup suspension rod 2 when tying the steel bars. The steel mesh can be fixed under the action of its own weight, and the height of the hook 6 should make the steel bars meet the minimum protective layer requirements. A hollow hole is set in the middle of the horizontal bracket 5, and the shape of the hollow hole is adapted to the suspension rod 2, so that the suspension rod 2 can pass through the center of the horizontal bracket 5.

[0029] When using this new type of stirrup, since the height of the stirrup gate-shaped bracket 7 is the same as the thickness of the concrete 9 floor, the construction workers can control the floor thickness according to the height of the stirrup bracket when pouring the concrete 9, thereby controlling the thickness of the steel bar protective layer. After the concrete 9 is initially leveled, before the concrete 9 is initially set, according to the pouring sequence, the rotating handle 1 is rotated in the opposite direction, and the bottom of the rotating handle 1 drives the suspension rod 2 and the hook 6 to move, so as to take out the stirrup, clean the residual concrete 9 on the stirrup, and stack it according to different models, so that it can be removed in time after pouring the concrete 9 and reused.

[0030] Working principle of the utility model: the utility model is a new type of reusable steel stirrup, which is provided with a hanger 2 structure, and the hook can be detached from the steel mesh 8, so that the stirrup can be reused, and the installation process is convenient and quick, thereby increasing construction efficiency and reducing construction cost; by setting the upper and lower supporting structures, the upper and lower supporting structures can calculate the height of the gate-shaped bracket 7 and the spacing between the hooks 6 according to the design thickness of the cast-in-place concrete 9 floor slab and the thickness of the protective layer of the steel mesh 8, so as to adapt to different construction requirements.

[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
