Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel structure construction, in particular to a steel structure construction lifeline. Background Art
[0002] During the process of steel structure construction lifeline, high-altitude operations are often involved. In order to ensure the safety of workers working at heights, it is often necessary to use a security device set on the already hoisted I-beam. At present, for traditional security devices, a fixture support is usually used to press tightly against the upper flange of the beam by bolts as the support, and the vertical pole is usually connected to the fixture support by welding.
[0003] When the existing technology is in use, it is fixed by screwing the bolts to tighten. However, when vibration occurs during use, the bolts may spin and loosen, and then cause loosening, affecting safety. Therefore, a steel structure construction lifeline that solves the above problems is needed. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems raised in the background art, and a steel structure construction lifeline is designed.
[0005] To achieve the above purpose, the technical solution of the utility model is as follows: a steel structure construction lifeline, including a vertical pole, a C-shaped block, a downward pressing screw rod, a clamping seat, a rotating column, a screwing hole, a guide rail, a lower pressing plate, a spring, and a limiting block. The lower part of the vertical pole is installed with a C-shaped block, and a downward pressing screw rod is bite-inserted on the C-shaped block. The lower end of the downward pressing screw rod is rotatably connected with a clamping seat. A rotating column is connected to the downward pressing screw rod, and a screwing hole is opened on the rotating column. A guide rail is installed on the vertical pole, and a lower pressing plate is slidably embedded on the guide rail. A spring is sleeved on the upper part of the guide rail. A limiting block is arranged on the lower pressing plate. The limiting block is a plurality of block structures distributed in a ring shape. A limiting block is arranged on the upper part of the rotating column. The limiting blocks on the lower pressing plate and the rotating column are in corresponding positions.
[0006] Furthermore, connecting ears are arranged on the vertical pole. A plurality of connecting ears are installed on the vertical pole, and the connecting ears are installed on both sides of the vertical pole.
[0007] Furthermore, a triangular block is arranged on the upper part of the C-shaped block. The two right-angle sides of the triangular block are respectively connected to the upper end of the C-shaped block and the vertical pole.
[0008] Furthermore, there are two downward pressing screw rods.
[0009] Furthermore, the guide rail is a rectangular rod-shaped structure.
[0010] Advantageous Effects:
[0011] The utility model provides a steel structure construction lifeline, which has the following beneficial effects. Through its structural design, the U-shaped block on the upright rod is sleeved on the steel structure, and then the rod-shaped structure is inserted into the screwing hole to drive the rotating column to rotate. At this time, the lower pressing plate is lifted upward, and then the rotating column rotates to drive the lower pressing screw to rotate. The rotation and descent of the lower pressing screw drive the clamping seat to clamp the steel structure, thereby realizing the fixation of the upright rod. After the clamping is completed, the lower pressing plate is released, and then the lower pressing plate moves downward under the pressing action of the spring on the guide rail. The limiting block on the lower pressing plate and the limiting block at the upper end of the rotating column are engaged with each other, thereby locking the angle of the lower pressing screw and preventing the lower pressing screw from spinning out due to vibration, increasing the installation stability of the steel structure construction lifeline.

[0020] Please refer to Figure 1-4 , the present utility model provides a technical solution: a steel structure construction lifeline, including a vertical pole 1, a U-shaped block 2, a downward pressure screw 3, a clamping seat 4, a rotating column 5, a screwing hole 6, a guide rail 7, a lower pressing plate 8, a spring 9, and a limiting block 10. The lower part of the vertical pole 1 is installed with a U-shaped block 2, and a downward pressure screw 3 is engaged and inserted on the U-shaped block 2. The lower end of the downward pressure screw 3 is rotatably connected with a clamping seat 4. A rotating column 5 is connected to the downward pressure screw 3, and a screwing hole 6 is opened on the rotating column 5. A guide rail 7 is installed on the vertical pole 1, and a lower pressing plate 8 is slidably embedded on the guide rail 7. A spring 9 is sleeved on the upper part of the guide rail 7, and a limiting block 10 is provided on the lower pressing plate 8. The limiting block 10 is a plurality of block structures distributed in a ring shape. A limiting block 10 is provided on the upper part of the rotating column 5, and the limiting block 10 on the lower pressing plate 8 and the limiting block 10 on the rotating column 5 are in corresponding positions.
