Abstract
Description
Technical Field
[0001] This invention relates to the field of suspended platform installation technology, and in particular to a counterweight-free suspended platform installation bracket for ultra-high parapet walls. Background Technology
[0002] High-altitude suspended platforms are widely used in the construction, curtain wall installation, insulation decoration and maintenance of high-rise and super high-rise buildings due to their flexibility and efficiency.
[0003] Conventional suspended platform installation methods mainly fall into two categories: one is to directly mount it on the roof or structural floor slab using a suspension mechanism, and the other is to install it across the parapet wall using counterweight high outriggers. The latter is more commonly used when dealing with parapet walls of standard height.
[0004] However, with the diversification of modern architectural design, a large number of building structures with extremely high parapet walls (e.g., exceeding the span of conventional suspended platform supports) have emerged. In such cases, the traditional counterweight-type high-leg installation method faces significant technical bottlenecks and construction challenges. First, this method has strict limitations on the height of the parapet wall; when the parapet wall is too high, the stability of the legs is difficult to guarantee, and there is a risk of overturning. Second, the installation of high legs requires a large amount of space above the parapet wall and on the roof, easily causing interference with subsequent professional works such as roof waterproofing, electromechanical pipelines, and decorative framing, seriously affecting the overall construction period. Furthermore, this method requires high structural integrity and load-bearing capacity at the top of the parapet wall, and the installation and dismantling process is complex, inefficient, and has poor reusability, increasing construction costs and safety risks.
[0005] Based on this, a counterweight-free suspended platform installation bracket for ultra-high parapet walls is proposed. Summary of the Invention
[0006] To address the aforementioned technical problems, this invention proposes a counterweight-free suspended platform mounting bracket for ultra-high parapet walls.
[0007] The technical solution to achieve the purpose of this invention is: a counterweight-free suspended platform mounting bracket for ultra-high parapet walls, comprising a wall body, and further comprising:
[0008] The support body serves as the main load-bearing component of the system; a suspension beam is installed on the support body, a hoisting wire rope is installed on the support body, and an upper limit stop is installed on the hoisting wire rope;
[0009] A connecting bracket is used to adjustably connect the bracket body and the suspension beam;
[0010] A pull-down steel wire rope system is used to diagonally tie and fix the rear end of the support body to the wall to balance the overturning moment generated by the forward extension of the basket;
[0011] The suspended basket body is suspended from the front end of the suspension beam of the support body by a hoisting wire rope.
[0012] Preferably, the support body includes the suspension beam and the connecting bracket, and the connecting bracket is fixedly connected to the support body by fastening bolts.
[0013] Preferably, the suspension beam is slidably connected to the connecting bracket, and the suspension beam is provided with multiple adjustment holes along its length to accommodate different extension lengths.
[0014] Preferably, the pull-down steel wire rope system includes two pull-down steel wire ropes, an embedded plate, and chemical anchors. One end of each pull-down steel wire rope is connected to the rear end of the suspension beam, and the other end is connected to the embedded plate fixed to the building structure via a U-shaped buckle. The embedded plate is anchored to the wall via the chemical anchors.
[0015] Preferably, the two pull-down steel wire ropes are arranged symmetrically at the rear end of the suspension beam, and the pull-down steel wire ropes are provided with fastening baskets for adjusting and pre-tensioning the tension.
[0016] Preferably, the embedded plate is a square steel plate, which is fixed by at least four chemical anchors.
[0017] Preferably, a fixing frame is fixedly connected to one side of the wall, a safety node is fixedly connected to the fixing frame, a safety rope is provided on the safety node, one end of the safety rope is independently fixed to a reliable structure on the roof, and the other end is connected to the suspended platform body.
[0018] Preferably, a fixing metal plate is fixedly connected to the bottom end of the bracket body, and a plurality of expansion bolts are provided on the fixing metal plate. An mounting plate is fixedly connected to the upper surface of the wall, and a fixing hole is provided on the upper surface of the mounting plate. The bracket body is fixedly connected to the wall through the expansion bolts and the fixing hole.
[0019] The significant advantages of this invention compared to existing technologies are:
[0020] Firstly, this invention employs an adjustable connecting bracket and a suspension beam with multiple adjustment holes, which can be flexibly adjusted according to the height of the parapet wall and the forward extension length of the suspended platform, adapting to the construction needs of different super high-rise buildings and complex facades. The bracket is directly fixed to the wall via expansion bolts and a pull-down steel wire rope system, eliminating the need for counterweights or high outriggers on the roof, saving installation space, avoiding interference with other roof construction projects, significantly improving installation efficiency, and shortening the construction cycle.
[0021] Secondly, this invention uses a downward-pulling steel wire rope system to diagonally anchor the rear end of the support to the wall, effectively balancing the forward tilting moment generated during suspended platform operation and preventing the support from overturning. The steel wire ropes are symmetrically arranged and equipped with turnbuckles to adjust the preload, ensuring uniform stress distribution. Simultaneously, an independent safety rope is reliably connected to the roof structure, forming double fall protection and significantly improving the safety of high-altitude operations.

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] This invention provides an improved, counterweight-free suspended platform mounting bracket for ultra-high parapet walls. The technical solution of this invention is as follows:
[0033] like Figure 1-6 As shown, a counterweight-free suspended platform mounting bracket for ultra-high parapet walls includes a wall 1, and also includes:
[0034] The support body 2 serves as the main load-bearing component of the system. A suspension beam 3 and a hoisting wire rope 6 are mounted on the support body 2, with an upper limit stop 7 on the hoisting wire rope 6. The support body 2, as the main load-bearing skeleton of the system, is preferably constructed from high-strength alloy structural steel, welded or bolted together, and possesses excellent bending, compressive, and torsional resistance. Its cross-section can be designed as rectangular or I-shaped to optimize mechanical properties and reduce weight. The suspension beam 3 is also made of high-strength steel, with a pulley or hanging point at its front end equipped with a wear-resistant bushing for guiding and suspending the hoisting wire rope 6.
[0035] The connecting bracket 13 is used to adjustably connect the support body 2 and the suspension beam 3. The suspension beam 3 is adjusted to the support body 2 through the connecting bracket 13. The connecting bracket 13 is usually made of thick steel plate by bending or casting, and has internal sliding grooves or clamping mechanisms. High-strength locking bolts are provided on the connecting bracket 13. A series of adjustment holes are precisely machined along the length of the web or flange of the suspension beam 3. These adjustment holes need to be chamfered or reinforced to prevent stress concentration. By selecting different adjustment hole positions and tightening the bolts, the forward extension length of the suspension beam 3 relative to the wall 1 can be adjusted steplessly or in stages. This design allows the support to flexibly adapt to the construction requirements of different building facades and the different working surfaces that the suspended platform needs to reach, realizing the function of "one machine for multiple uses".
[0036] The pull-down wire rope 10 system is used to diagonally tie and fix the rear end of the support body 2 to the wall 1 to balance the overturning moment generated by the forward extension of the basket.
[0037] The suspended platform body 8 is suspended from the front end of the suspension beam 3 of the support body 2 via a hoisting wire rope 6. An upper limit stop 7 is fixed to the hoisting wire rope 6. When the suspended platform is raised to the set height, the stop will trigger a limit switch or mechanical stop, automatically cutting off the lifting power or preventing further ascent, thus preventing the suspended platform from "overshooting" and ensuring the safety of equipment and personnel.
[0038] like Figure 1 and Figure 3 As shown, the support body 2 includes a suspension beam 3 and a connecting bracket 13, which is fixedly connected to the support body 2 by fastening bolts.
[0039] The suspension beam 3 is slidably connected to the connecting bracket 13. The suspension beam 3 is provided with multiple adjustment holes along its length to accommodate different extension lengths.
[0040] like Figure 5 and Figure 6 As shown, the pull-down steel wire rope 10 system includes two pull-down steel wire ropes 10, an embedded plate 16, and chemical anchors 18. One end of each pull-down steel wire rope 10 is suspended from the rear end of the crossbeam 3, and the other end is connected to the embedded plate 16 fixed to the building structure via a U-shaped clip 20. The embedded plate 16 is anchored to the wall 1 via the chemical anchors 18. The embedded plate 16 is a square or rectangular steel plate, the thickness of which needs to be determined by calculation, and the surface can be hot-dip galvanized for corrosion protection. The chemical anchors 18 use high-strength bolts and high-performance epoxy resin or vinyl ester resin adhesives.
[0041] Two pull-down steel wire ropes 10 are symmetrically arranged at the rear end of the suspension beam 3. Each pull-down steel wire rope 10 is equipped with a fastening basket 19 for adjusting and pre-tensioning the tension. The pull-down steel wire ropes 10 are preferably made of galvanized steel wire rope or stainless steel wire rope, possessing high breaking strength, corrosion resistance, and fatigue resistance. Each wire rope is equipped with alloy pressed joints or wedge joints at both ends to ensure reliable connection. The fastening baskets 19 are typically high-quality carbon steel forged OO-type or CC-type turnbuckles with left- or right-hand threads at both ends, providing length adjustment, pre-tensioning, and locking functions.
[0042] The embedded plate 16 is a square steel plate, which is fixed by at least four chemical anchors 18.
[0043] like Figure 1 and Figure 2 As shown, a fixing frame 9 is fixedly connected to one side of the wall 1. A safety node 4 is fixedly connected to the fixing frame 9, and a safety rope 5 is installed on the safety node 4. One end of the safety rope 5 is independently fixed to a reliable roof structure, and the other end is connected to the suspended platform body 8. The safety rope 5 is usually a synthetic fiber rope or stainless steel wire rope with a plastic sheath, which is lightweight, flexible, and wear-resistant. The safety node 4 is a special connecting ring made of cast steel or steel plate.
[0044] A fixing metal plate 11 is fixedly connected to the bottom of the bracket body 2. Multiple expansion bolts 12 are provided on the fixing metal plate 11. An installation plate 14 is fixedly connected to the upper surface of the wall 1. Fixing holes 15 are opened on the upper surface of the installation plate 14. The bracket body 2 is fixedly connected to the wall 1 through the expansion bolts 12 and the fixing holes 15.
[0045] The specific working method is as follows: Determine the bracket installation point at the top parapet wall of wall 1 to ensure that the structure of wall 1 meets the load-bearing requirements. Use measuring tools to locate the anchor point of the bracket body 2 and the pull-down steel wire rope 10 system, and mark the installation position of the embedded plate 16 on wall 1;
[0046] The support body 2 is fixed to the top of the wall 1 using a fixing metal plate 11 and expansion bolts 12. The suspension beam 3 is connected to the support body 2 via a connecting bracket 13. The corresponding adjustment hole position on the suspension beam 3 is selected according to the forward extension length of the suspended platform, and then fixed with fastening bolts.
[0047] Drill holes at the marked locations on wall 1 and insert chemical anchors 18 to fix the embedded plate 16 to the surface of wall 1. Connect one end of the pull-down wire rope 10 to the rear end of the suspension beam 3 via a U-shaped buckle 20, and the other end to the connecting seat 17 on the embedded plate 16 via a fastening basket 19. Adjust the pretension of the pull-down wire ropes 10 on both sides symmetrically to ensure balanced force. Pass the hoisting wire rope 6 through the pulley system at the front end of the suspension beam 3, and connect the lower end to the suspended platform body 8. Install an upper limit stop 7 on the hoisting wire rope 6 to prevent the suspended platform from being over-lifted. Set a safety node 4 on the side fixing frame 9 of wall 1, fix one end of the safety rope 5 to a reliable structure on the roof, and connect the other end to the suspended platform body 8 to form an independent fall protection.
[0048] Check the firmness of all connection nodes, bolts, wire ropes, and anchor points. Perform a no-load test run on the suspended platform to observe the stability of the support structure and the stress on the wire rope system. Conduct a load test; only after confirming there are no abnormal deformations or loosening can it be put into use. During operation, regularly check the condition of each component. Disassembly should be performed in reverse order: first remove the suspended platform and safety system, then loosen the pull-down wire rope 10 and the support fixing components, and finally remove the support body 2 and the embedded plate 16, restoring the wall surface to flatness.
[0049] The technical means disclosed in this invention are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this invention are common knowledge to those skilled in the art.
