Description

Technical Field

[0001] The utility model relates to the technical field of construction platforms, in particular to a high-altitude construction work platform. Background Art

[0002] The construction site requires numerous high-altitude work locations for steel plate shear walls, necessitating the installation of multiple aerial work platforms. Traditionally, scaffolding platforms have been constructed using steel pipes and steel springboards. This approach places specific demands on the foundation and space, not only requiring stringent construction requirements and significant training and inspection time for management personnel, but also impacting their work efficiency. Irregular platform construction can easily lead to falls from heights. Furthermore, the complex and time-consuming process impacts the construction schedule.

[0003] A Chinese utility model, published on October 13, 2017, with publication number CN 206554484 U, relates to the field of steel structure construction technology and discloses a temporary operating platform tripod. The tripod comprises a tripod body comprising a vertical section, a horizontal section, and an inclined section. The temporary operating platform tripod also includes a hanging plate and a hanging lug. The hanging lug is welded to the structural member to be constructed, and the hanging plate is mounted above the vertical section of the tripod body, which clips onto the hanging lug. This utility model utilizes a hanging lug, which remains as a permanent fixture and can be directly clipped onto the tripod. This makes installation and removal simple, significantly reducing time spent on setting up and dismantling the temporary operating platform. The tripod is also reusable, significantly reducing costs. However, in this patent, the safety rope is looped through a hanging ring. Because the safety rope can move relative to the hanging ring, it can easily become loose after a period of use. Summary of the Invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2 As shown, a high-altitude work platform for shear wall construction, as described in Example 1 of the present invention, includes a platform support frame, columns 2, and a lifeline 3. The platform support frame is used to connect to the shear wall. The columns 2 are provided with at least two columns 2, at least two of which are detachably connected to the upper outer ends of the platform support frame. A lifeline 3 is detachably connected between the columns 2 to protect construction workers on the platform. The columns 2 are provided with a locking mechanism for locking the lifeline 3 to prevent it from sliding or loosening.

[0029] Further, if Figure 3 As shown, the locking mechanism includes a locking member 51 that is inserted through the column 2. The locking member 51 is inserted transversely through the column 2. The locking member 51 is adapted to move with the column 2. One end of the locking member 51 is provided with a hook for securing the lifeline 3, and the other end is connected to a movable drive member for driving the locking member 51 to move. A space for inserting the lifeline 3 is formed between the hook and the column 2. The movable drive member causes the locking member 51 to move the hook toward the column 2, causing the hook to move closer to the column 2, thereby locking the lifeline 3. Furthermore, the hook's opening is located above the locking member 51, preventing the lifeline 3 from falling out of the opening.

[0030] Furthermore, the mobile driving member includes a locking nut 52 threadedly connected to the locking member 51 , the locking nut 52 is rotatably connected to the column 2 , and an external thread cooperating with the locking nut 52 is provided on the outer side of the locking member 51 .

[0031] Specifically, the locking nut 52 is coaxially connected to a circular steel sheet at one end near the column 2. Two symmetrically arranged cover plates are fixedly attached to the column 2. Each cover plate forms a cavity between the column 2 and the column 2, which accommodates half of the circular steel sheet. Both cover plates are provided with holes for the locking nut 52 to pass through and rotate. In other words, each cover plate has a hole for half of the locking nut 52 to pass through. A cover plate is welded to the column 2, and then half of the circular steel sheet is inserted into the cavity. Another cover plate is then placed on the other half of the circular steel sheet, and the two cover plates are then welded and fixed. The circular steel sheet is inserted into the cavity of the two cover plates, allowing the locking nut 52 to rotate with the column 2. The column 2 can be made of square steel pipe, and the cover plates can be directly welded to the side of the column 2. Alternatively, the column 2 can be made of round steel, and the cover plates are first welded to a base plate to form the cavity, which is then welded to the column 2.

[0032] Furthermore, the lifeline 3 comprises a steel wire rope, a stainless steel rod, an aluminum alloy rod, or a steel bar. When a rigid rod such as a stainless steel rod, an aluminum alloy rod, or a steel bar is used, multiple locking mechanisms can be provided on the column 2 to lock the rigid rods that are disconnected on both sides.

[0033] Example 2 is different from Example 1 in that Figure 3 As shown, the locking mechanism also includes a limiting structure, which includes baffles 53 located on both sides of the hook to prevent the locking member 51 from rotating. The baffles 53 on both sides are provided with aligned, transversely extending L-shaped slots for receiving the lifeline 3, allowing the lifeline 3 to be inserted from the upper end of the L-shaped slot into the horizontal section of the L-shaped slot. The horizontal portion of the L-shaped slot is aligned with the opening of the hook, so that the hook can clamp the lifeline 3 within the horizontal section of the L-shaped slot after lateral movement.

[0034] Furthermore, a hole 21 for inserting the hook end is provided on the column 2 at a position aligned with the hook end, so that the hook end can be inserted into the hole 21 to tighten the lifeline more and more. The above-mentioned limiting structure can be provided with a base plate for fixing to the column, and the baffle 53 is provided on the base plate, so that the limiting structure is an integral unit, and the base plate is provided with a hole aligned with the hole 21.

[0035] Furthermore, the platform support frame includes at least two tripods 1, each tripod 1 is provided with a column 2, and a platform plate 7 is placed on two or more adjacent tripods 1. In a preferred embodiment, the tripod 1 is made of angle steel.

[0036] Example 3 differs from Example 1 in that a fixing nut 6 is provided on the outer upper end of the tripod 1, and an external thread, stud, or screw is provided at the lower end of the column 2 to cooperate with the fixing nut, so that the column 2 can be detachably connected to the tripod 1. When the lower end of the column 2 is provided with an external thread to cooperate with the fixing nut, the column 2 is made of round steel.

[0037] Embodiment 4 differs from embodiment 1 in that a safety rope 4 is hung on the lifeline 3, and the safety rope 4 is connected to the worker to provide protection for the worker.
