Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, specifically an attached lifting scaffolding hanging safety protection device, which solves the problem of insufficient scaffolding protection height caused by the staggered design of balconies. Background Technology

[0002] Traditional attached lifting scaffolds have a protective height of 3.5 stories (approximately 10.5 meters). However, in staggered balcony designs, odd-numbered and even-numbered balconies are offset to each other, causing some areas that have not been demolded to exceed the protective height of the attached lifting scaffolds (1 story, approximately 3 meters). Existing technologies often use temporary steel pipe scaffolds for protection, which suffers from low installation efficiency, high costs, and incompatibility with the construction of attached lifting scaffolds. Utility Model Content

[0003] This utility model provides an attached safety protection device for the under-hanging of a lifting scaffold, the specific structure of which includes:

[0004] 1) Main protective structure

[0005] Mesh-type stainless steel rope mesh (1): Vertical arrangement, mesh size ≤ 50mm, rope diameter ≥ 6mm, tensile strength ≥ 8kN / node;

[0006] Upper fixed module (2): rigidly connected to the lower edge crossbeam (5) of the attached lifting scaffold by bolts (201) and metal washers (202);

[0007] Lower fixed module (3): The lower end of the net-shaped stainless steel rope net (1) is anchored to the edge of the protruding balcony structure of the next floor using expansion hooks (301), with an anchoring depth ≥50mm, that is, the length of the expansion sleeve (302) is ≥50mm, and the concrete matrix strength is ≥C25.

[0008] 2) Lateral stabilization components (4)

[0009] The lateral stabilizing component (4) is connected to the building's vertical structure (7) or the vertical support steel pipe (402).

[0010] Mode 1 (Structural entity anchoring): When there is a concrete vertical structure (7) on the side of the net-type stainless steel rope net (1), an expansion hook group (401) is used, which is arranged vertically at intervals along the concrete vertical structure (7) and forms a flexible connection with the side of the net-type stainless steel rope net (1) through the hooks.

[0011] Mode 2 (Auxiliary support anchoring): When there is no structural entity on the side of the net-shaped stainless steel rope net (1), a vertical support steel pipe (402) is set up and anchored to the upper floor structure (8) and the edge of the balcony structure (6) respectively through the upper fixed sleeve (403) and the lower fixed base (404). The side of the net-shaped stainless steel rope net (1) is flexibly connected to the vertical support steel pipe (402) through the adjustable buckle (405).

[0012] The beneficial effects achieved by this utility model are as follows:

[0013] The protection height is extended from 3.5 to 4.5 stories, covering the exposed and unformed areas of the staggered balconies. Through a compatible design of two lateral stabilization modes, it can utilize the existing building structure or achieve full-scene coverage through an independent support system.

[0014] The lower fixing module and the lateral stabilizing component adopt a standardized interface, which supports quick assembly and disassembly. When the attached lifting scaffold is lifted, the restrictions of the lower fixing module and the lateral stabilizing component are released. The device of this utility model is lifted to the upper level along with the attached lifting scaffold through the upper fixing module, which is convenient, quick and easy to operate.

[0015] This utility model device is designed for installation on all balcony locations. When there is no balcony structure in the area covered by this device for staggered balconies, the stainless steel rope netting in the corresponding area can shrink to about 1 / 3 of the coverage height due to its self-shrinking property, which has a certain storage capacity and avoids the safety hazards caused by the accumulation of redundant netting.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figure 1-4 This embodiment provides an attached lifting scaffolding hanging safety protection device, which includes a net-type stainless steel rope net (1), an upper fixing module (2), a lower fixing module (3), and a lateral stabilizing component (4). The installation steps are as follows:

[0023] Step 1: Drill holes in the lower edge crossbeam (5) of the attached lifting scaffold, with a spacing of ≤0.35m, insert bolts (201) and pre-tighten them;

[0024] Step 2: Insert the bolt (201) into the upper end of the mesh-type stainless steel rope net (1), add the metal washer (202) and tighten it;

[0025] Step 3: Insert expansion hooks (301) at the edge of the next-floor balcony with a spacing of ≤0.35m to fix the lower end of the net-type stainless steel rope net (1);

[0026] Step 4: Install the lateral stabilizing component (4) and adjust the tension until the net-type stainless steel rope net (1) is not loose.

[0027] Step 5: After completing the construction of the protected area, release the restrictions of the lower fixed module (3) and the lateral stabilizing component (4), and let the fixed net-type stainless steel rope net (1) retract freely and hang down under the lower edge beam (5) of the attached lifting scaffold. As the attached lifting scaffold is lifted to the next floor, repeat steps one to four and reuse it.

[0028] In this embodiment, the lateral stabilizing component (4) is connected to the building vertical structure (7) or the vertical support steel pipe (402), and is divided into two different installation modes depending on whether there is a building structure entity on the side edge of the net-shaped stainless steel rope net (1): Mode 1 (structural entity anchoring): When there is a concrete vertical structure (7) on the side of the net-shaped stainless steel rope net (1), an expansion hook group (401) is used, which is arranged vertically at intervals along the concrete vertical structure (7), and forms a flexible connection with the side of the net-shaped stainless steel rope net (1) through the hooks; Mode 2 (auxiliary support anchoring): When there is no structural entity on the side, a vertical support steel pipe (402) is set, and is anchored to the upper floor structure (8) and the balcony structure edge (6) respectively through the upper fixed sleeve (403) and the lower fixed base (404), and the side of the net-shaped stainless steel rope net (1) forms a flexible connection with the vertical support steel pipe (402) through the adjustable buckle (405).

[0029] Through the above measures, edge protection of the staggered balcony area after the attached lifting scaffolding is lifted is achieved, and the problem of insufficient protection height of the attached lifting scaffolding caused by the high formwork construction of staggered balconies is solved.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
