Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a construction method for a suspended and fixed device for curtain wall construction. Background Technology

[0002] Electric suspended platforms are construction machinery used for high-altitude operations, widely used in exterior wall construction, maintenance, and cleaning. As building shapes become increasingly aesthetically pleasing and complex, the lifting and lowering of the suspended platform during exterior wall construction can be affected by the building's shape, preventing it from reaching the ground and causing the platform to suspend in the air, increasing safety hazards.

[0003] Conventional practices include: 1. When there is no curtain wall keel, the suspended platform is normally lowered onto the building or suspended in the air, using its own weight to prevent displacement. However, normally lowering the suspended platform onto the building or suspending it in the air is a violation of regulations. In windy weather, the suspended platform will sway continuously in the air, and in strong winds, it may be blown into the air, creating a significant safety hazard. If workers climb into the suspended platform through a window, the swaying will cause them to lose their footing and hold on, posing a significant safety risk. 2. When there is a curtain wall keel, the method for suspending the electric suspended platform is as follows: The suspended platform is normally lowered onto the building or suspended in the air, and then tied to the curtain wall keel with ropes to ensure its stability. The suspended platform and the curtain wall keel must be secured together with ropes. If soft ropes are used for tying, they will pull the suspended platform outwards, but they will have no effect when the platform moves inwards. In windy weather, the suspended platform will collide with the curtain wall keel, causing damage to both. If steel wire ropes are used for tying, they can play a certain role when the platform is tied to the curtain wall keel, but the tying is relatively troublesome. When dismantling, the steel wire ropes cannot be reused, and may even be cut, resulting in economic losses.

[0004] Chinese patent CN205382699U discloses a suspended platform for shotcreting construction of building exterior walls. The platform includes a platform with railings around its perimeter. Both ends of the platform are connected to the front ends of a roof-suspended cantilever beam via steel wire ropes. The rear end of the roof-suspended cantilever beam passes through a pre-embedded anchor ring in the roof and is welded and fixed to the pre-embedded anchor ring. The suspended platform also includes a first connecting steel rod, a second connecting steel rod, and a pre-embedded connecting sleeve. The pre-embedded connecting sleeve is embedded in the exterior wall. One end of the second connecting steel rod is connected to the pre-embedded connecting sleeve, and the other end of the second connecting steel rod is connected to one end of the first connecting steel rod via a hook. The other end of the first connecting steel rod is welded and fixed to both ends of the front side of the suspended platform. This patent connects the steel rods through pre-embedding and welding, which is complex, requires damage to the wall, and has limited adjustability, preventing adjustments based on the construction progress. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a construction method for a suspension and fixing device for curtain wall construction, which is applicable to curtain wall construction scaffolds and prevents displacement of the electric scaffold suspension platform from the influence of the ground and building shape when it is suspended in the air.

[0006] The technical solution adopted by this invention to solve its technical problem is: The construction method of the suspended and fixed device for curtain wall construction as described in this invention includes the following steps: A1. Based on the window positions on the building wall, locate the suspended platform of the suspended scaffold, and then place the suspended platform of the suspended scaffold in the location position using the suspension mechanism and steel wire rope; A2. Place the rear fixing component onto the suspended platform of the basket, and then fix it according to the height position of the window. Connect the middle adjustment component to the rear fixing component through the telescopic rod. A3. Insert the front-end connecting component into the middle-end adjusting component. Adjust the angles of the front-end connecting component and the middle-end adjusting component according to the position of the suspended platform of the basket. The front-end connecting component extends into the window and is connected to the side wall of the window through a set of mountain-shaped clips inside the front-end connecting component. A4. Tighten the front connecting component, then adjust the length of the telescopic rod and tighten the middle adjusting component and telescopic rod to complete the installation; A5. After installation, inspect the suspended platform to ensure it is securely installed and does not shift.

[0007] in: In step A1, the suspended platform of the suspended basket is flush with the window and is in a horizontal state.

[0008] When the rear-end fixing component is inserted in step A2, the U-shaped clip in the rear-end fixing component is first placed on the top of the suspended platform of the basket. Then, the U-shaped clip is passed through the steel sheet and fixed with a nut. A C-shaped adjustment plate is welded to the bottom of the steel sheet. Support bolts are installed on the left and right sides of the opening of the C-shaped adjustment plate. At the same time, the suspension nut is fitted onto the support bolt in the middle of the C-shaped adjustment plate, and the telescopic rod is welded to the suspension nut.

[0009] In step A2, the telescopic rod includes a metal sleeve with a threaded steel bar inside. Both the metal sleeve and the threaded steel bar have several holes spaced apart. Connecting bolts pass through the holes to fix the metal sleeve and the threaded steel bar. The threaded steel bar is welded to the suspension nut.

[0010] In step A3, the mid-end adjustment component includes a fixed plate with a strip groove in the middle. Slanted nuts are provided on both the left and right sides of the strip groove, and metal sleeves are threaded into the slanted nuts.

[0011] In step A3, the front-end connecting component includes a threaded screw, and a set of U-shaped clips are fitted onto the threaded screw. The U-shaped clips are rotatably set perpendicular to the threaded screw. Then, fixing nuts are fixed on the inner and outer sides of the U-shaped clips away from the middle adjustment component, and adjusting nuts are set on the outer side of the U-shaped clips near the middle adjustment component, and fixing nuts are set on the inner side. The threaded screw passes through the strip groove and is fixed by the connecting nut and the limiting nut.

[0012] In step A3, adjusting the angles of the front-end connecting component and the middle-end adjusting component includes adjusting the threaded rod in the front-end connecting component to be perpendicular to the window, and adjusting the fixing plate in the middle-end adjusting component to be perpendicular to the threaded rod and parallel to the building wall.

[0013] In step A3, the position of the mountain-shaped clip near the middle adjustment component is adjusted according to the thickness of the window sidewall. The mountain-shaped clip is fixed by the adjusting nuts and fixing nuts on both sides.

[0014] In step A4, the telescopic rod is adjusted according to the distance between the building and the suspended platform, so that the building and the suspended platform are parallel.

[0015] After the construction is completed, the suspension and fixing device for the curtain wall operation scaffold is disassembled. The specific steps are as follows: B1. Loosen the adjusting nut and fixing nut on the front connecting component, remove the mountain-shaped clip from the window, loosen the limiting nut and connecting nut on the middle adjusting component, and remove the threaded rod. B2. Flip down the middle adjustment component, telescopic rod and rear fixing component to the outside of the suspended platform, with the telescopic rod parallel to the suspended platform in the vertical direction; then the suspended platform is used in conjunction with the suspension mechanism and wire rope.

[0016] When using curtain wall keel construction, this invention can adjust the height of the suspended platform of the scaffold according to the position of the construction keel, fix the front end connecting component to the keel, and adjust the position of the mountain-shaped card according to the thickness of the keel for fixation.

[0017] The beneficial effects of this invention are: This invention employs a combination of threaded steel bars and steel rods with multiple components for connection, which improves the connection strength of the suspended platform and prevents it from shifting forward and backward while suspended in the air. At the same time, by directly transferring part of the load to the wall, it significantly enhances the suspension device's ability to resist forward tilting moments, reduces the risk of overturning due to insufficient counterweight or uneven load, and ensures safety and reliability. This invention can be used regardless of whether a curtain wall keel is used, greatly expanding its scope of application.

[0018] In the front-end connecting assembly, a set of U-shaped clips is secured to the window sidewall by adjusting nuts on the threaded rod. Then, fixing nuts stabilize the U-shaped clip structure inside, preventing slippage and allowing adjustment of the U-shaped clip spacing. This allows for adjustment and fixation based on different window positions and thicknesses or keels, ensuring usability for window sidewalls and keels of varying positions and thicknesses, greatly improving the adaptability of the invention and enhancing its stability. The threaded rod passes through a slot and can be adjusted left and right within the slot for fine-tuning. The distance of the threaded rod can also be adjusted using limit nuts. The middle adjustment assembly connects two telescopic rods, forming a triangular structure, which adjusts the stability of the middle adjustment assembly and the suspended platform. Support bolts are sequentially tightened through a C-shaped adjustment plate and a suspension nut, ensuring the suspension nut can rotate along the support bolts.

[0019] This invention allows for telescopic adjustment at three points: between the window and the front connecting component, between the front connecting component and the middle adjusting component, and at the telescopic rod. This adjusts the position of the suspended platform, making it suitable for complex working conditions involving various distances and angles between the suspended platform and the building, as well as wall and keel thicknesses. During use, the front connecting component can be fixed at different positions on the window sidewall, facilitating construction by adjusting the suspended platform's position. Furthermore, the distance between the building and the middle adjusting component, and the distance between the middle adjusting component and the rear fixing component, can be adjusted using the telescopic rod. This multi-stage adjustment method ensures that the distance between the suspended platform and the building can be adjusted during construction, both indoors and on the suspended platform itself. This ensures the correct position of the suspended platform for both close-range and long-range construction, solving the problem that existing suspended platforms can only be adjusted based on the suspension mechanism and wire rope position, and can only be vertically positioned. The suspension mechanism and wire rope cannot adjust the platform's position or the angle between the platform and the connecting component in a timely manner during construction.

[0020] Easy to use, the device is freely flipped during operation. It is flipped using a suspension nut, and when needed, it is flipped to the appropriate angle with the suspended platform. This prevents slippage, beam torsion, or fulcrum sinking of the suspension device under long cantilevered or heavy loads, ensuring the suspended platform remains in its designated working position. After use, it is flipped back to a vertically parallel position with the suspended platform, without occupying any space. Under different working conditions, after one project is completed, the device can be used normally for the next project, achieving cyclical reuse. Attached Figure Description
