Description

Technical Field

[0001] The utility model belongs to the technical field of building construction devices, and in particular relates to a steel cage suspension device. Background Art

[0002] During cast-in-place pile construction, the drill rig is positioned, the hole is drilled, the first step is cleared, the steel cage is lowered, the second step is cleared, and concrete is poured. After pouring the concrete, the steel cage needs to be fixed at a certain height. Because the newly poured concrete has no strength, the steel cage is prone to sinking. Therefore, the steel cage must be suspended after pouring to prevent it from sinking before the concrete strength is formed. The current method is to use a crisscross frame to hang the steel cage on a crisscross frame pin stretcher. This crisscross frame is highly applicable and suitable for various cast-in-place pile construction. However, it is bulky and inconvenient to move. It is not universal for bored piles of different diameters. It is also expensive, generally costing 30,000 to 40,000 yuan per piece, making it less economical and more expensive. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a steel cage suspension device which is easy to move, easy to use, low in cost and highly versatile.

[0004] The purpose of the present utility model is achieved through the following technical solutions, such a steel cage hanging device includes a hanging steel block, a hanging groove is provided at the bottom of the hanging steel block toward the top, the hanging steel block is hung on the upper end of the wall of the steel casing through the hanging groove, and at least four hanging steel blocks are hung on the steel casing, which are distributed around the center of the steel casing and at equal intervals, and a hanging hole is provided on the hanging steel block, and a lifting lug is connected to the hanging hole, and the lifting lug is connected to the top of the steel cage through a steel wire rope.

[0005] The beneficial effects of the utility model are as follows: compared with the prior art, the steel cage in the steel casing is suspended by four hanging steel blocks suspended on the steel casing, and the hanging steel blocks are provided with hanging grooves and hanging holes, which is not only convenient to use and move, but also has the advantages of low production cost and strong versatility; and at least four hanging steel blocks are hung on the steel casing, which has the advantages of more uniform force distribution of the steel cage suspension and better stability.

[0006] Preferably, the hanging direction of the hanging groove is parallel to the side of the hanging steel block, and the distance h between the bottom of the hanging groove and the bottom of the hanging steel block is 1 / 3 of the height H of the hanging steel block; the hanging groove and the hanging steel block are parallel, which not only makes the force of the hanging steel block uniform during the hanging process, but also makes the force of the steel casing uniform, and the proportional distribution arrangement between the hanging groove and the hanging steel block makes the force of the hanging groove more stable and the structure of the hanging steel block more stable.

[0007] Preferably, the height m of the hanging steel block where the hanging hole is located is lower than the depth M of the hanging groove; in this way, during the process of suspending the steel cage through the hanging hole, the force point can be lower than the force point between the hanging groove and the steel casing, so that the suspension is more stable and safer, and the hanging steel block will not fall off the steel casing.

[0008] Preferably, one end angle of the hanging steel block is set as an inclined surface, and the inclined surface faces the steel cage in the steel casing; by setting the inclined surface, not only is the suspension between the lifting ear and the wire rope facilitated (because the diameter of the steel cage is smaller than the diameter of the steel casing, the wire rope will be in an inclined direction during the suspension process), but the weight of the hanging steel block is also further reduced, thereby further reducing the production cost.

[0009] Preferably, the upper end of the inclined surface is flush with the upper circular tangent of the hanging hole, and the lower end of the inclined surface is flush with the left circular tangent of the hanging hole; this makes the suspension inclination range between the lifting ear and the wire rope larger, and can be applied to the suspension of steel cages of different diameters in the steel casing, with better versatility.

[0010] Preferably, a handle bar is fixed to the top of the hanging steel block by welding, and the handle bar is located above the hanging groove; by providing the handle bar, it is convenient to extract and put the hanging steel block, and at the same time, the handle bar is located above the hanging groove, which makes the extraction process more convenient and can be separated from the steel casing by directly pulling it up.

[0011] Preferably, a shelf block is provided at the bottom of one side of the hanging groove on the hanging steel block, and the length direction of the shelf block is perpendicular to the length direction of the hanging steel block, and when the hanging steel block is hung on the steel casing, the shelf block is against the ground; through the setting of the above structure, the requirement for bearing the stratum force at the bottom of the steel casing can be reduced, so that the suspension stability of the entire structure is better.
