Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a stirrup hanger. Background Art

[0002] When hoisting stirrups in the construction industry, workers often violate regulations for convenience and to save money. For example, on-site hoisting often involves situations like the following: after the stirrups are processed, workers will neatly stack the stirrups next to the processing plant because the hopper is insufficient or temporarily unused. When they are ready to use, workers will directly pass a wire rope through a pile of stirrups and then hoist them directly onto the board. This situation poses a great risk of hidden dangers. Since the steel bars are tough when under stress, the stirrups may fall at any time, causing an object impact accident. This device can greatly improve safety and reduce accidents while meeting normal construction requirements. Utility Model Content

[0004] Preferably, the hole is a threaded hole, and the bottom of the fixing screw is provided with threads and is threadedly connected to the hole.

[0005] Preferably, the hole is a hole with a smooth inner wall, the diameter of the bottom threaded portion of the fixing screw is smaller than the diameter of the fixing screw body, and after the fixing screw is inserted into the hole, the bottom threaded portion of the fixing screw is inserted into the bottom of the bracket and fixed by the fixing nut.

[0006] Preferably, each of the columns is provided with a rope threading hole below the lifting ear, one end of the two anti-falling steel wire ropes is tied and fixed on two adjacent columns, and the other end is fixed in the rope threading hole of the diagonal column.

[0007] To sum up, the utility model has the following beneficial effects: the utility model provides a stirrup hoist, which is safer than the traditional method of directly tying the stirrups for lifting; compared with the use of a hopper for lifting, this hoist reduces the time for workers to carry things back and forth, and is more convenient for the management of the construction site, eliminating the phenomenon of over-lifting and false loading, and improving construction efficiency to a certain extent.

[0011] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0012] Reference Figure 1 The utility model discloses a stirrup hanger, comprising a support for carrying stirrups, wherein the four corners of the support 1 are provided with columns 2 extending upward, the support 1 is provided with a lateral restriction device for preventing the stirrups from translating, and the columns 2 are provided with a longitudinal restriction device for preventing the stirrups from moving vertically, the lateral restriction device comprises a plurality of holes 3 opened on the support 1, and four fixing screws 4 are provided above the support 1, and the four fixing screws 4 can be inserted into the holes 3 for fixing, so as to limit the horizontal self-movement of the stirrups. According to the degree, the longitudinal limiting device includes two anti-falling steel wire ropes 5 fixed on the column 2, and the two anti-falling steel wire ropes 5 are cross-tied to prevent the stirrups from moving in the vertical direction during the lifting process. The column 2 is provided with a lifting ear 8. In the utility model, the bracket 1 has multiple rows of holes, and the holes are inserted with fixing screws 4. The four fixing screws 4 can prevent the stirrups from moving left and right. At the same time, the two anti-falling steel wire ropes 5 are cross-pierced and fixed, which plays a role in preventing the stirrups from moving in the vertical direction during lifting.

[0013] In the present invention, the hole is a threaded hole, and the bottom of the fixing screw 4 is provided with a thread and is threadedly connected to the hole, or the hole of the present invention is a hole with a smooth inner wall, and the diameter of the threaded part at the bottom of the fixing screw 4 is smaller than the diameter of the rod body of the fixing screw 4. After the fixing screw 4 is inserted into the hole, the threaded part at the bottom of the fixing screw 4 is inserted into the bottom of the bracket 1 and fixed by the fixing nut 6. Both settings of the fixing screw 4 and the hole can play the role of installing the fixing screw 4.

[0014] In addition, each of the columns 2 is provided with a rope threading hole 7 below the lifting ear 8 , and one end of the two anti-falling steel wire ropes 5 is tied and fixed to two adjacent columns 2 , and the other end is fixed in the rope threading hole 7 of the diagonal column 2 .

[0015] Before processing the sling, it is necessary to conduct experiments to determine the load capacity of the sling. The site must be checked and accepted to prevent overloading. The sling columns 2 and other parts must be made of steel with strong tensile properties. After determining the size of the stirrups, the worker selects a suitable position on the hole of the bracket 1 according to the size of the stirrups, and fixes the fixing screw 4 with the fixing nut 6 to limit the horizontal freedom of the stirrups and prevent the stirrups from moving left and right. Stack the stirrups on the bracket 1. When the load limit is reached (the maximum load can be tested experimentally first), Figure 1 , insert the B anti-slip wire rope into the b port, and the A anti-slip wire rope into the a port to prevent the stirrups from moving vertically during the lifting process. After completing the above operations, hang the hooks on the lifting ears 8 of the four columns 2 for lifting.

[0016] As mentioned above, although the present invention has been represented and described with reference to specific preferred embodiments, it should not be interpreted as a limitation of the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention defined in the appended claims.
