AI Technical Summary
In the existing technology, the suspension device of the sloping roof hanging basket cannot be adjusted from the exterior wall according to the construction requirements of the exterior wall, which leads to inconvenience in construction and safety hazards. In addition, traditional hanging baskets cannot meet the construction needs of sloping roofs.
The method involves creating through holes in the sloping roof structure panel and eaves, and using fixing components and steel wire ropes to fix the suspended platform to the sloping roof structure panel. The first end of the steel wire rope passes through the first through hole and is connected to the fixing component, and the second end passes through the second through hole and is connected to the suspended platform. The fixing component transmits force, allowing the sloping roof structure panel to act as a counterweight, avoiding the need for a separate counterweight installation. Pads are placed on the eaves to support the steel wire rope, and the synchronous winding and unwinding of the steel wire rope is achieved in conjunction with the winding mechanism.
This solution addresses the problem of excessive distance between the suspended platform and the exterior wall caused by excessively long eaves, ensuring a proper distance between the platform and the wall, improving construction safety and stability, reducing the impact on roof construction, extending the service life of the wire rope, and preventing the platform from tilting through a synchronous deployment and retraction mechanism.

Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to a suspended platform installation structure and installation method for a cantilevered sloping roof. Background Technology
[0002] In the process of exterior wall decoration, suspended platforms are commonly used for construction work. Suspended platforms have become an essential construction tool in the construction industry and have a wide range of applications. Commonly used suspended platforms employ a counterweight system, and their fixed erection methods include tie-rod type and cantilever type. Among these, there are two common anchoring methods for the suspended platform suspension device: counterweight suspension fixing and connection to the floor structure. During the installation and erection of suspended platforms, unconventional roof shapes, such as sloping roofs, are frequently encountered. Traditional suspended platforms are not suitable for these roof structures, requiring the use of unconventional suspended platform suspension devices and erection methods.
[0003] Currently, there are several suspended platform support systems for sloping roofs. For example, patent document CN110397261A discloses a method for installing a suspended platform on a sloping roof with cantilevered eaves. However, the suspended platform is positioned close to the outer edge of the roof gutter, making it impossible to adjust the distance from the exterior wall according to construction requirements, thus hindering its use during construction. Another example is patent document CN112049406A, which discloses a method for vertically installing a suspended platform for cantilevered eaves on a sloping roof and its installation structure. This includes a pre-embedded sleeve fixed to the eaves gutter template, with a sealing nut covering the upper part of the sleeve. The pre-embedded sleeve has pre-reserved reinforcing bars and additional reinforcing bars on both sides, located within the eaves structure and reinforcing the gutter structure. A bolt passes through the pre-embedded sleeve, with a pad at the edge of the gutter structure fitted on the upper and lower parts of the bolt. A lifting ring is connected to the lower end of the bolt, and a steel wire rope for the suspended platform passes through the lifting ring, with a pre-reserved curved section on the wire rope. The technical solution disclosed in the patent document with patent number CN112049406A will affect the roof construction when implemented. This is mainly because the construction process is increased by reserving hanging bars and adding steel bars, which occupy the construction wall area and require secondary finishing work.
[0004] In conclusion, due to environmental limitations, the existing construction methods and installation structures for setting up suspended scaffolds on sloping roofs will affect roof construction and pose certain safety hazards. Summary of the Invention
[0005] The purpose of this invention is to provide a suspended platform installation structure and method for sloping roofs with eaves, in order to improve the technical problems in the prior art where the eaves are too long, the suspended platform is far from the wall, making construction difficult, and steel pipe frames and counterweights cannot be installed on sloping roofs, without affecting roof construction as much as possible.
[0006] The objective of this invention is achieved through the following technical solution:
[0007] Firstly, this application provides a suspended platform installation structure for a sloping roof with eaves, comprising:
[0008] A sloping roof structure panel, wherein at least two first through holes are provided on the sloping roof structure panel, penetrating the upper and lower surfaces;
[0009] An eave is connected to the sloping roof structure panel and extends horizontally toward the side away from the sloping roof structure panel. At least two second through holes are vertically opened on the eave, and the second through holes are set close to the sloping roof structure panel.
[0010] A pad, wherein the pad is disposed on the eaves and located between the second through hole and the sloping roof structure slab;
[0011] At least two sets of steel wire ropes, each set of steel wire ropes including a main steel wire rope and a secondary steel wire rope, the main steel wire rope and the secondary steel wire rope each having a first end and a second end, the first end extending through the first through hole to the underside of the sloping roof structure panel, the second end being placed on a pad and extending through the second through hole and suspended in the direction of gravity, the second end being connected to the suspended basket, and the space under the sloping roof structure panel being defined as a concealed layer;
[0012] A fixing component is provided, which is connected to the first end of the wire rope and located within the lining layer. The width and length of the fixing component are both greater than the diameter of the first through hole. When the wire rope is subjected to tension, the fixing component abuts against the sloping roof structure panel and can compress and fix the wire rope between the fixing component and the sloping roof structure panel.
[0013] In some possible embodiments, the fixing component includes:
[0014] At least two suspended platform brackets, each set of wire ropes is connected to one of the suspended platform brackets, the suspended platform brackets having U-shaped grooves with the openings of the U-shaped grooves facing the sloping roof structure panel;
[0015] The square steel bar passes through the U-shaped grooves of the two suspended basket brackets in sequence and is fixed to the suspended basket brackets with bolts. The square steel bar abuts against the sloping roof structure plate.
[0016] After the first end of the wire rope passes through the first through hole, it is wound around the hanging basket bracket. Before the wire rope is tightened, the square steel and the hanging basket bracket are movably connected. After the wire rope is tightened, the hanging basket bracket is clamped by the tension and the square steel is pressed against the wire rope, so that a fixed connection is formed between the square steel and the hanging basket bracket. The part of the wire rope that passes through the first through hole is squeezed and fixed between the sloping roof structure plate and the square steel by the square steel.
[0017] In some possible embodiments, the pad is provided with a fixed pulley, and the second end is wound around the fixed pulley and extends to the second through hole; the pad is a detachable load-bearing object separately set on the eaves, or a building structure formed by concrete casting on the eaves; a snake-skin rubber tube is sleeved at the overlap of the wire rope and the pad, at the edge of the wire rope and the first through hole, and at the edge of the wire rope and the second through hole;
[0018] The first through hole is perpendicular to the upper and lower surfaces of the sloping roof structure panel. Both the first and second through holes are hourglass-shaped and consist of three parts, from top to bottom: the upper part, the middle part, and the lower part. The upper part is an inverted conical hole, the middle part is a cylindrical hole, and the lower part is a regular conical hole.
[0019] In some possible embodiments, a number of intersecting reinforcing ribs are embedded in both the sloping roof structure slab and the eaves. The reinforcing ribs are arranged in two layers, with multiple reinforcing ribs in each layer intersecting each other. Concrete is poured to fill the area defined by the reinforcing ribs.
[0020] At least four rope clamps are provided on the second end of the wire rope connected to the suspended platform. The second end of the wire rope is wound back upwards to overlap with the suspended part of the wire rope. The two parts of the wire rope are clamped together by the rope clamps. The wire rope at the connection to the suspended platform is wound back to form a heart-shaped loop. From one side of the heart-shaped loop to the other side, the distance between the first three rope clamps is 50mm to 60mm, and the distance between the third and fourth rope clamps is 60mm to 80mm, so that the wire rope can form a safety bend with a height of not less than 40mm. Finally, a margin of not less than 140mm is left behind the fourth rope clamp.
[0021] In some possible embodiments, the eaves sloping roof suspended platform installation structure further includes a winding mechanism, which is disposed within the veneer and fixed to the sloping roof structure plate or fixedly connected to the fixing component. The winding mechanism is used to connect the steel wire rope and wind up the steel wire rope.
[0022] The winding mechanism includes:
[0023] A fixing frame, which is fixed to the fixing component or fixed to the sloping roof structure panel;
[0024] A winding drum, which is rotatably mounted on the fixed frame;
[0025] A winding motor is fixed to the fixed frame and connected to the output of the take-up drum.
[0026] Furthermore, the fixing frame includes two fixing columns, two supporting columns, and two opposing baffles. Each of the two baffles has a corresponding mounting hole. The two fixing columns and the two supporting columns are located between the two baffles and are fixedly connected by passing through the corresponding mounting holes.
[0027] The winding drum is located between two baffles, with one end of the winding drum passing through one of the baffles and extending to one side of the baffle, where it is fixedly connected to the output end of the winding motor. The other end of the winding drum is rotatably connected to the baffle. The surface of the winding drum has several equally spaced storage slots for storing the wire rope.
[0028] Two limiting plates are also fitted on the winding drum. The two limiting plates are arranged opposite each other to define the winding space, so that the wire rope can be wound and confined within the winding space.
[0029] In some possible embodiments, the fixed frame, the winding drum, and the limiting plate constitute a hoisting assembly. A winding mechanism includes two hoisting assemblies and a winding motor, as well as a conveyor chain. The two hoisting assemblies are arranged in parallel. The portion of the winding drum located between the limiting plate and the baffle is provided with several teeth. The teeth are arranged at equal intervals along the circumference of the winding drum. The conveyor chain is sleeved on the two winding drums and meshes with the teeth. There are two conveyor chains, located at the two ends of the two winding drums respectively, and located between the limiting plate and the baffle. The conveyor chains enable a winding motor to drive the two hoisting assemblies to move synchronously.
[0030] Furthermore, one or more first limiting holes are provided on the side of the baffle, and multiple second limiting holes are provided on the limiting plate in a circular array. When the winding mechanism winds the wire rope to a certain position, the limiting pins are inserted into the first and second limiting holes in sequence to limit the rotation of the winding drum.
[0031] Secondly, this application provides a method for installing a suspended platform on a sloping roof with eaves, used to install the aforementioned suspended platform installation structure on a sloping roof with eaves, the method comprising:
[0032] The structural slabs and eaves of the sloping roof are reinforced with strength.
[0033] The drilling positions on the sloping roof structure slab and the eaves are determined based on the location of the suspended platform.
[0034] Drill holes in the sloping roof structure panel and the eaves to form a first through hole and a second through hole, respectively;
[0035] Based on the drilling positions on the eaves, determine the placement and height of the pads, and then place the pads on the eaves.
[0036] The first end of the steel wire rope passes through the first through hole and is connected to the fixing component in the quilted layer. The second end of the steel wire rope passes through the pad and extends through the second through hole to hang vertically in the direction of gravity. When the fixing component is subjected to the tension of the steel wire rope, the fixing component abuts against the sloping roof structure panel.
[0037] Connect the second end of the wire rope to the suspended platform.
[0038] Furthermore, the method for strengthening the sloping roof structural slab and eaves includes:
[0039] Before pouring concrete for the sloping roof structural slab and eaves, two layers of reinforcing ribs are set inside the floor slab formwork, each layer of which includes several reinforcing ribs arranged in a crisscross pattern.
[0040] Several reinforcing bars are connected and fixed to the reinforcing bars of the floor slab formwork;
[0041] Concrete pouring.
[0042] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:
[0043] The present invention provides an installation structure and method for a suspended platform on a sloping roof with eaves. It mainly uses a fixing component to fix the steel wire rope to the sloping roof structural plate, so that the sloping roof structural plate can play a role in balancing the load and counterweight, eliminating the need to install a separate concrete counterweight. Furthermore, by opening a second through hole in the eaves, the steel wire rope can be suspended close to the outer wall, solving the problem in the prior art where the suspended platform is too far from the outer wall due to the excessive length of the eaves.
[0044] In detail, the main method involves passing the first end of the steel wire rope through the first through hole and the second end through the second through hole. The first end is connected to a fixing component, which provides limiting and force transmission. Specifically, the tension of the steel wire rope is transferred to the fixing component, which then transfers the force to the sloping roof structural slab, allowing the sloping roof structural slab to act as a counterweight. The second end of the steel wire rope passes through the second through hole and connects to the suspended platform, ensuring that the distance between the suspended platform and the exterior wall is not affected by the eaves length, thus meeting construction requirements. Here, the first and second ends refer to the first end of the main steel wire rope, the first end of the auxiliary steel wire rope, the second end of the main steel wire rope, and the second end of the auxiliary steel wire rope, respectively. In addition, pads are placed on the eaves, positioned between the second through hole and the sloping roof structural slab. This allows the steel wire rope to pass over the pads before passing through the second through hole, enabling part of the steel wire rope to rest on the pads. This provides support and distributes the force, making the installation structure more stable and reliable, and extending the service life of the steel wire rope.
[0045] In addition, this application uses a winding motor to drive two winding drums to rotate synchronously. Each winding drum corresponds to a set of wire ropes. Driven by a winding motor, the two winding drums simultaneously wind or unwind the two sets of wire ropes, which can ensure that both ends of the suspended platform rise or fall synchronously, preventing the suspended platform from tilting due to asynchronous winding of the two sets of wire ropes, which could cause personnel or materials to fall.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0055] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0056] To facilitate understanding of the present application, the spline curves and arrows used in the reference numerals in the accompanying drawings are explained below: spline curves without arrows indicate solid parts, that is, parts with solid structures; spline curves with arrows indicate virtual parts, that is, parts without solid structures.
[0057] Please see Figures 1 to 4 This application provides a suspended platform installation structure for a sloping roof with eaves, comprising:
[0058] The sloping roof structure panel 1 has at least two first through holes 11 that penetrate its upper and lower surfaces. Preferably, the first through holes 11 are opened perpendicularly to the upper and lower surfaces of the sloping roof structure panel 1.
[0059] Eaves 2 are connected to the sloping roof structure slab 1 and extend horizontally toward the side away from the sloping roof structure slab 1. At least two second through holes 21 are vertically opened on the eaves 2, penetrating the upper and lower surfaces of the eaves 2. The second through holes 21 are set close to the sloping roof structure slab 1.
[0060] Pad 5, which is provided on the eaves 2 and located between the second through hole 21 and the sloping roof structure slab 1;
[0061] At least two sets of wire ropes 3, each set of wire ropes 3 includes a main wire rope and a secondary wire rope. Both the main wire rope and the secondary wire rope have a first end and a second end. The first end extends through the first through hole 11 to the underside of the sloping roof structure slab 1. The second end is placed on the pad block 5 and extends through the second through hole 21 and hangs in the direction of gravity. The second end is connected to the hanging basket 8. The space under the sloping roof structure slab 1 is defined as the quilt layer.
[0062] The fixing component 4 is connected to the first end of the wire rope 3 and is located in the lining layer. The width and length of the fixing component 4 are both greater than the diameter of the first through hole 11. When the wire rope 3 is subjected to tension, the fixing component 4 abuts against the sloping roof structure plate 1.
[0063] The technical solution provided in this application mainly involves using a fixing component 4 to fix the steel wire rope 3 to the sloping roof structural slab 1, so that the sloping roof structural slab 1 acts as a counterweight, eliminating the need for separate counterweight concrete installation. Furthermore, by opening a second through hole 21 in the eaves 2, the steel wire rope 3 can be suspended close to the exterior wall 7, solving the problem in existing technologies where the eaves 2 are too long, causing the suspended platform 8 to be too far from the exterior wall 7. Specifically, the first end of the steel wire rope 3 passes through the first through hole 11, and the second end passes through the second through hole 21. The first end is connected to the fixing component 4, which provides limiting and force transmission. Specifically, the tension of the steel wire rope 3 is transmitted to the fixing component 4, which then transmits the force to the sloping roof structural slab 1, making the sloping roof structural slab 1 act as a counterweight. The second end of the steel wire rope 3 passes through the second through hole 21 and connects to the suspended platform 8, ensuring that the distance between the suspended platform 8 and the exterior wall 7 is not affected by the length of the eaves 2, thus meeting construction requirements. In addition, by setting a pad 5 on the eaves 2, and the pad 5 is located between the second through hole 21 and the sloping roof structure slab 1, the wire rope 3 will pass through the pad 5 before passing through the second through hole 21, so that part of the wire rope 3 can be laid on the pad 5, which will provide certain support and share the force of the wire rope 3, which will help to make the installation structure more stable and reliable, and extend the service life of the wire rope 3.
[0064] It should be noted that, for the main wire rope and the auxiliary wire rope, since the first end of the main wire rope and the auxiliary wire rope are connected to the same components, namely the fixing component 4, and the connection positions are the same, and the second end of the main wire rope and the auxiliary wire rope are both connected to the suspended platform 8, and the main and auxiliary wire ropes are a set of wire ropes 3, for the sake of simplicity in the following description, when describing the wire rope 3, it refers to a set of wire ropes, that is, including the main wire rope and the auxiliary wire rope, unless otherwise specified. In this implementation plan, each set of wire ropes is equipped with a main wire rope and an auxiliary wire rope in order to enhance the safety of workers working in the suspended platform 8. That is, each set of wire ropes has two wire ropes, so even if one wire rope breaks due to an accident or other factors, the other wire rope can still bear the load, thereby further enhancing safety.
[0065] Compared to the most common existing technology that uses supports and counterweights to install the suspended platform 8 using the lever principle, the technical means employed in this application overcomes the difficulties of installing counterweights and supports on slopes. It is better suited to building structures with sloping eaves 2 because this technology eliminates the need for separate counterweights and supports as lever arms; instead, it directly utilizes the slope and eaves 2 structure itself as lever arms and counterweights, simplifying installation and providing better adaptability for buildings with eaves 2. Compared to some current technical solutions that use pre-embedded sleeves and lifting rings, such as the method disclosed in patent number CN112049406A, this technical solution minimizes the impact on roof construction. It avoids increasing the construction process and occupying construction wall space due to pre-reserved lifting rods and additional steel bars, facilitating subsequent secondary finishing work, and minimizing the impact on roof waterproofing.
[0066] It should be noted that the aforementioned exterior wall 7 mainly refers to the building's exterior wall, which is the object that workers need to construct while riding in the suspended platform 8; the aforementioned "hidden floor" is mainly an area defined by the sloping roof structure slab 1 and the concrete slab structure of the building's top floor. Regarding the number of wire ropes 3, in this embodiment, two sets of wire ropes 3 are mainly used. In other embodiments, more than two sets can be used, mainly depending on the actual situation such as the size of the suspended platform 8, its load-bearing capacity, and its balance. However, the holes for the wire ropes 3 are one-to-one, meaning that one set of wire ropes 3 needs to correspond to one first through hole 11 and one second through hole 21.
[0067] Please see Figure 2 and Figure 3 In some embodiments, the fixing component 4 includes:
[0068] At least two suspended basket brackets 42, each set of steel wire ropes 3 is connected to one suspended basket bracket 42, the suspended basket bracket 42 has a U-shaped groove 421, the opening of the U-shaped groove 421 is set towards the sloping roof structure slab 1;
[0069] Square steel 41 passes through the U-shaped grooves 421 of the two hanging basket brackets 42 in sequence and is fixed to the hanging basket brackets 42 with bolts. Square steel 41 abuts against the sloping roof structure plate 1.
[0070] The main function of the suspended platform bracket 42 is to connect the steel wire rope 3. In this embodiment, the U-shaped groove 421 of the suspended platform bracket 42 is set to open towards the sloping roof structure slab 1, so that the U-shaped groove 421 can cooperate with the sloping roof structure slab 1 to define an area for the square steel 41 to pass through, and when the suspended platform bracket 42 is subjected to the tension of the steel wire rope 3, the square steel 41 can abut and limit its position against the sloping roof structure slab 1. In order to facilitate the square steel 41 to pass through two suspended platform brackets 42 in sequence, the U-shaped grooves 421 are generally arranged in parallel. Before the wire rope 3 is tightened, the square steel 41 and the suspended basket bracket 42 are movably connected. When the square steel 41 abuts against the surface of the sloping roof structure slab 1, the part of the wire rope 3 that passes through the first through hole 11 is squeezed at the surface of the end wall of the first through hole 11. After the wire rope 3 is tightened, the suspended basket bracket 42 is pulled by the tension and holds the square steel 41 and abuts against the wire rope 3, thereby forming a fixed connection between the square steel 41 and the suspended basket bracket 42. After being pulled, the wire rope 3 also forms a fixed connection with the square steel 41 and the suspended basket bracket 42. Specifically, after the first end of the wire rope 3 passes through the first through hole 11, it is wound around the basket bracket 42. When the winch starts and winds the wire rope 3, the wire rope 3 will be stretched by the force and tighten the basket bracket 42, pressing the basket bracket 42 and the square steel 41 against the sloping surface of the sloping roof structure slab 1. At this time, the square steel 41 will squeeze the wire rope 3 extending out of the first through hole 11 against the plate surface of the end wall of the first through hole 11.
[0071] In some embodiments, a pad 5 is provided near the second through hole 21 on the eaves 2, specifically between the second through hole 21 and the outer wall 7. The second end of the steel wire rope 3 rests on the pad 5 and extends through the second through hole 21. The pad 5 can be a detachable load-bearing object separately installed on the eaves 2, or it can be a building structure directly formed on the eaves 2 by concrete casting. There are no limitations, as long as the steel wire rope 3 has a resting point before passing through the second through hole 21. By setting the pad 5, an additional support point is added between the steel wire rope 3 and the first through hole 11 and the second through hole 21, preventing the steel wire rope 3 from being pulled too long, affecting the stress and shortening the life of the steel wire rope 3. The pad 5 can withstand the force from the steel wire rope 3 and continue to transfer the force to the eaves 2, which is beneficial for force distribution and improves the safety of the suspended platform 8 installation.
[0072] Furthermore, a braided rubber tube 6 is fitted at the overlap of the wire rope 3 and the pad block 5, at the edge abutment of the wire rope 3 and the first through hole 11, and at the edge abutment of the wire rope 3 and the second through hole 21. The braided rubber tube 6 reduces the wear of the wire rope 3 and extends its service life.
[0073] Furthermore, a fixed pulley is provided on the pad 5. The second end of the wire rope 3 is wound around the fixed pulley and extends to the second through hole 21. By setting the fixed pulley, the wire rope 3 can have an additional force point between the first through hole 11 and the second through hole 21, avoiding excessive suspension length of the wire rope 3, which is detrimental to the stability of the installation structure; and setting this force point as a fixed pulley helps to assist the movement of the wire rope 3, making the movement of the wire rope 3 smoother and reducing the wear of the wire rope 3.
[0074] In some embodiments, both the first through hole 11 and the second through hole 21 are hourglass-shaped. To facilitate understanding of the hourglass shape, the first through hole 11 is illustrated by dividing it into three parts, from top to bottom: an upper part, a middle part, and a lower part. The upper part is an inverted conical hole, the middle part is a cylindrical hole, and the lower part is a regular conical hole. This design facilitates subsequent hole repair and waterproofing.
[0075] It should be noted that one of the purposes of this embodiment is to enable workers to carry out construction work on the outer wall 7 from the suspended platform 8. Therefore, the vertical distance between the second through hole 21 and the outer wall 7 is less than or equal to 20cm to ensure that workers can carry out normal work on the outer wall 7 without being affected by the extension length of the eaves 2 when riding in the suspended platform 8. In addition, the concrete thickness of the sloping roof structural slab 1 is set to 120mm, and double-layer steel bars with a diameter of 10mm are arranged inside the structural slab.
[0076] In some embodiments, at least four rope clamps are provided on the second end of the wire rope 3 connected to the suspended platform 8. A portion of the second end of the wire rope is wound upwards to overlap with the suspended portion of the wire rope 3, and then the rope clamps are used to clamp the two portions of the wire rope 3 together, increasing the strength of the wire rope 3. The wire rope 3 wound back at the connection to the suspended platform 8 to form a heart-shaped loop, making the connection between the wire rope 3 and the suspended platform 8 more reliable. From one side of the heart-shaped loop towards the other, the spacing between the first three rope clamps is 50mm to 60mm, and the spacing between the third and fourth rope clamps is 60mm to 80mm, allowing the wire rope 3 to form a safety bend with a height of approximately 40mm. Finally, a 140mm allowance is left after the fourth rope clamp. The first end of the wire rope 3 can be clamped in the same manner as the second end described above, or it can be wound around a winding mechanism and connected and fixed to the winding mechanism.
[0077] In some embodiments, a plurality of intersecting reinforcing ribs are embedded in both the sloping roof structural slab 1 and the eaves 2 to enhance their strength. The reinforcing ribs are arranged in two layers, with the multiple reinforcing ribs in each layer intersecting each other. The area defined by the reinforcing ribs is filled with poured concrete.
[0078] Please see Figure 2 and Figure 4 In some embodiments, the suspended platform installation structure for the sloping roof also includes a winding mechanism 9. The winding mechanism 9 is located within the concealed layer and is fixed to the sloping roof structure panel 1 or fixedly connected to the fixing component 4. The winding mechanism 9 is used to connect and wind up the steel wire rope 3. If the winding mechanism 9 is fixed to the sloping roof structure panel 1, then during disassembly, both the winding mechanism 9 and the fixing component 4 need to be disassembled. However, the specific fixing position and size of the winding mechanism 9 are not limited and can be applied to sloping roof structure panels 1 of various sizes. If the winding mechanism 9 is fixedly connected to the fixing component 4, disassembly is more convenient; only the fixing component 4 needs to be removed from the sloping roof structure panel 1. However, there are certain limitations on the size and installation position of the winding mechanism 9, which must conform to the size of the fixing component 4, so that the fixing position of the winding mechanism 9 corresponds to the fixing position of the fixing component 4. The specific fixing method can be selected according to actual needs. By setting up a winding mechanism 9, the wire rope 3 can be automatically recycled after the suspended basket 8 is disassembled, which facilitates the quick storage and retrieval of the wire rope 3.
[0079] Please see Figure 4 For the receiving mechanism 9, it includes:
[0080] The fixing frame 91 is fixed to the fixing component 4 or to the sloping roof structure panel 1;
[0081] A winding drum 92 is rotatably mounted on a fixed frame 91.
[0082] The winding motor 93 is fixed on the fixed frame 91 and connected to the output of the take-up drum 92.
[0083] The fixing frame 91 includes two fixing columns 911, two support columns 912, and two opposing baffles 913. Corresponding mounting holes are provided on each of the two baffles 913. The two fixing columns 911 and two support columns 912 are located between the two baffles 913 and are fixedly connected through their respective mounting holes. A winding drum 92 is positioned between the two baffles 913, with one end extending through one of the baffles 913 and fixedly connected to the output end of the winding motor 93. The other end of the winding drum 92 is rotatably connected to the baffle 913. The surface of the winding drum 92 has several equally spaced storage slots 921 for storing the wire rope 3.
[0084] Furthermore, two limiting plates 94 are also fitted on the winding drum 92. The two limiting plates 94 are arranged opposite to each other to define the winding space so that the wire rope 3 can be wound and confined within the winding space.
[0085] In some embodiments, see Figure 5A hoisting assembly is formed by a fixed frame 91, a winding drum 92, and a limiting plate 94. A winding mechanism 9 includes two hoisting assemblies, a winding motor 93, and a conveyor chain 95. The two hoisting assemblies are arranged in parallel opposite directions. Several teeth are provided on the portion of the winding drum 92 located between the limiting plate 94 and the baffle 913. These teeth are evenly spaced along the circumference of the winding drum. The conveyor chain 95 is sleeved on the two winding drums 92 and engages with the teeth. Two conveyor chains 95 are provided, located at the two ends of the two winding drums 92 respectively, and between the limiting plate 94 and the baffle 913. Through the conveyor chains 95, the winding motor 93 drives the two hoisting assemblies to move synchronously, improving the synchronization of the wound wire rope, saving costs, and reducing space occupation. Of course, the conveyor chain 95 can also be replaced with a conveyor belt, thus replacing the chain drive between the two winding drums 92 with a belt drive.
[0086] Furthermore, in some embodiments (not shown in the figures), one or more first limiting holes are provided on the side of the baffle 913, and multiple second limiting holes are provided on the limiting plate 94 in a circumferential array. When the winding mechanism 9 winds the wire rope to a certain position, limiting pins are sequentially inserted into the first and second limiting holes to limit the rotation of the winding drum 92 and improve its load-bearing capacity. After the limiting pins are inserted into the first and second limiting holes, the basket 8 can be further prevented from falling accidentally due to the weight pulling the wire rope 3.
[0087] The winding mechanism 9 serves two purposes. First, it is used to store the wire rope 3 after the exterior wall 7 construction is completed. Second, during wall construction, after the current work surface at a certain height is completed, the suspended platform 8 needs to be lowered to the next work surface. At this time, the winding mechanism 9 is activated to lower a certain length of wire rope 3, allowing the suspended platform 8 to reach the next work surface. Furthermore, after the wall construction is completed, to store the wire rope 3, first, the wire rope 3 is pulled out from the fixing component 4, and one end of the wire rope 3 is nailed into the storage groove 921 using an iron pin. Then, the winding motor 93 is activated, driving the winding drum 92 to wind up the wire rope 3. Pulling the wire rope 3 out of the fixing component 4 can be done by canceling the connection between the fixing component 4 and the wire rope 3, i.e., removing the wire rope 3 from the fixing component 4, or the wire rope 3 can remain passing through the fixing component 4 without affecting the winding process.
[0088] This embodiment is equipped with two sets of wire ropes 3. The same winding motor 93 drives two winding drums 92 to rotate synchronously. Each winding drum 92 corresponds to one set of wire ropes 3. Driven by the winding motor 93, the two winding drums 92 synchronously wind or unwind the two sets of wire ropes 3, which can ensure that both ends of the suspended basket 8 rise or fall synchronously, and prevent the suspended basket 8 from tilting due to asynchronous winding of the two sets of wire ropes 3, which could cause personnel or materials to fall.
[0089] Based on the above-described suspended platform installation structure for sloping roofs with eaves, this application also provides a method for installing a suspended platform for sloping roofs with eaves. Please refer to [link to relevant documentation]. Figure 6 Specifically, it includes:
[0090] S1. Strengthen the structural slabs and eaves of the sloping roof;
[0091] S2. Determine the drilling positions on the sloping roof structural slab and eaves based on the location of the suspended platform;
[0092] S3. Drill holes in the sloping roof structural slab and eaves to form the first through hole and the second through hole, respectively;
[0093] S4. Based on the drilling positions on the eaves, determine the placement and height of the pads, and then place the pads on the eaves.
[0094] S5. Pass the first end of the steel wire rope through the first through hole and connect it to the fixing component in the quilted layer. The second end of the steel wire rope passes through the pad and extends through the second through hole to hang vertically in the direction of gravity. When the fixing component is subjected to the tension of the steel wire rope, the fixing component abuts against the sloping roof structure panel.
[0095] S6. Connect the second end of the wire rope to the suspended platform.
[0096] In detail, the structural strength of the sloping roof structure 1 and eaves 2, which act as lever arms and counterweights, is first enhanced to ensure they have sufficient strength to withstand the weight of the suspended platform 8, steel wire ropes 3, the materials and equipment to be lifted, and the workers themselves, ensuring reliable strength support. The specific amount of strength enhancement required for the sloping roof structure 1 and eaves 2, and the load capacity (dead and live loads), is calculated based on the actual weight to be borne and the specific installation structure. After the strength enhancement of the sloping roof structure 1 and eaves 2 is completed, holes are made in both structures. These holes are primarily for the steel wire ropes 3 to pass through and for installing limiting steel wire ropes 3. The location of the holes is determined before drilling, based on the actual position of the suspended platform 8 and load calculations. Once the hole locations are determined, drilling tools are used to create the first through hole 11 and the second through hole 21. The number of first through holes 11 and the number of second through holes 21 correspond one-to-one, and are mainly determined by the number of wire ropes 3 required on the suspended platform 8. For example, if the suspended platform 8 is narrow, only two sets of wire ropes 3 need to be connected to the middle positions on the left and right sides of the suspended platform 8 to ensure its balance. In this case, only two sets of wire ropes 3 are needed, and correspondingly, two first through holes 11 and two through holes 21 are opened. On the other hand, if the suspended platform 8 is wide, wire ropes 3 need to be connected to all four corners of the suspended platform 8 to maintain balance. In this case, four wire ropes 3 are needed, and correspondingly, four first through holes 11 and four second through holes 21 are opened. It should also be noted that the through holes correspond one-to-one with the wire ropes 3, and two or more wire ropes 3 are not allowed to pass through a single through hole. After the first through hole 11 and the second through hole 21 are both drilled, the required position and height of the pad block 5 are calculated based on the drilling location, the distance between the first through hole 11 and the second through hole 21, and the height difference between them. This allows the wire rope 3 to be placed on the pad block 5, distributing some of the force to the pad block 5 and providing support for the wire rope 3. After the pad block 5 is in place, the workers pass the first end of the wire rope 3 through the first through hole 11 and connect it to the fixing component 4 in the inner layer. The second end of the wire rope 3 passes through the pad block 5 and the second through hole 21, hanging vertically in the direction of gravity. The first end is subjected to the force of the second end, and the fixing component 4 is pulled by the wire rope 3 to abut against the sloping roof structure slab 1. Finally, the workers connect the second end of the wire rope 3 to the suspended platform 8.
[0097] This concludes the entire installation process.
[0098] In some embodiments, the method for strengthening the sloping roof structural panel 1 and the eaves 2 includes:
[0099] Before pouring concrete for the sloping roof structural slab 1 and the eaves 2, two layers of reinforcing ribs are set in the floor slab formwork, each layer of which includes several reinforcing ribs arranged in a crisscross pattern.
[0100] Several reinforcing bars are connected and fixed to the reinforcing bars of the floor slab formwork;
[0101] Concrete pouring.
[0102] By setting reinforcing ribs in the sloping roof structural slab 1 and the eaves 2, the strength of the sloping roof structural slab 1 and the eaves 2 can be effectively improved, enabling them to bear higher loads. Furthermore, after subsequent construction is completed, there is no need to remove the reinforcing ribs, so it has little impact on the finishing work.
[0103] It should also be noted that both the first through hole 11 and the second through hole 21 are hourglass-shaped. Setting the first through hole 11 and the second through hole 21 in an hourglass shape allows for easy passage of the wire rope 3 through the through holes while simplifying subsequent finishing work. Specifically, if embedded parts are used to connect and fix the wire rope 3, then the embedded parts need to be removed later, the removed portion needs to be backfilled, and waterproofing work needs to be done at the removal site, which is very troublesome. However, by making the through holes hourglass-shaped in this application, and with a maximum diameter of 40mm, after the installation structure of the suspended platform 8 is removed later, only the through holes need to be backfilled and sealed, without significantly affecting waterproofing. The sealing operation involves filling and smoothing the through holes twice with fine aggregate concrete, followed by water curing.
[0104] In addition, the vertical distance between the second through hole 21 and the outer wall 7 is less than or equal to 20cm, which makes it easier for workers to carry out construction on the outer wall 7 from the suspended platform 8.
[0105] In some embodiments, the fixing component 4 includes:
[0106] At least two suspended basket brackets 42, each wire rope 3 is connected to a suspended basket bracket 42, the suspended basket bracket 42 has a U-shaped groove 421, the opening of the U-shaped groove 421 is set towards the sloping roof structure slab 1;
[0107] Square steel 41, which passes sequentially through the U-shaped grooves 421 of the two suspended basket brackets 42 and is fixed to the suspended basket brackets 42 with bolts, and abuts against the sloping roof structure plate 1; the step of passing the first end of the steel wire rope 3 through the first through hole 11 and connecting it with the fixing component 4 in the quilted layer includes:
[0108] The first end of the wire rope 3 is passed through the first through hole 11 into the quilted layer, and the first end of the wire rope 3 is connected and wound around the hanging basket bracket 42;
[0109] The square steel 41 is passed through the U-shaped groove 421 and fixed to the U-shaped groove 421 of the hanging basket bracket 42 using bolts and nuts.
[0110] With the openings of the square steel 41 and the U-shaped channel 421 facing the sloping roof structure slab 1, the square steel 41 comes into contact with the sloping roof structure slab 1 due to the tension at the other end of the wire rope 3.
[0111] The fixing component 4 mainly consists of a square steel bar 41 and a suspended platform bracket 42. Both the square steel bar 41 and the suspended platform bracket 42 are existing finished products that can be directly purchased from the market and are commonly used components in this technical field. This application's solution utilizes the square steel bar 41 inserted into the U-shaped groove 421 of the suspended platform bracket 42, with the opening of the U-shaped groove 421 facing the sloping roof structure slab 1, thereby achieving the fixing and limiting of the wire rope 3 by the fixing component 4. Furthermore, the contact between the square steel bar 41 and the sloping roof structure slab 1 facilitates the transfer of both live and dead loads to the sloping roof structure slab 1, thus distributing the load.
[0112] In some embodiments, before the steps of passing the first end of the wire rope 3 through the first through hole 11 and connecting it to the fixing component 4 within the inner layer, the second end of the wire rope 3 passing through the pad 5 and extending through the second through hole 21 to hang vertically in the direction of gravity, and before the fixing component 4 abuts against the sloping roof structure slab 1 when subjected to the tension of the wire rope 3, a fixed pulley is further included on the pad 5. Specifically, after determining the position and height of the pad 5 and installing the pad 5, a fixed pulley is installed at a certain point on the pad 5. The location of the fixed pulley needs to be on the path of the wire rope 3 and needs to allow the wire rope 3 to naturally wrap around the fixed pulley. The fixed pulley can be fixed to the pad 5 using bolts. By installing a fixed pulley, the smoothness of the wire rope 3's movement is improved, the wear of the wire rope 3 by the pad 5 is reduced, and the service life of the wire rope 3 is extended.
[0113] Understandably, before connecting the second end of the wire rope 3 to the suspended platform 8, the suspended platform 8 needs to be assembled. Since the assembly of the suspended platform 8 is existing technology, it will only be briefly described here. The suspended platform 8 consists of a base plate, basic sections (reinforcing bars), a basket hoist, and installation locks. The main steps are: selecting a flat ground as the installation surface, raising the base plate by at least 200mm, aligning the joints of the basic sections, installing the baskets, with the lower baskets placed on one side of the work surface, and connecting them with bolts. After pre-tightening, ensure the entire platform frame is straight. Install the hoist at both ends of the side baskets, ensuring the brackets for installing the safety locks face outwards from the platform. Finally, install the safety locks, which primarily prevent the suspended platform 8 from tilting or falling.
[0114] In addition, each suspended platform 8 requires a safety rope. Safety rope installation: Before use, each suspended platform 8 is equipped with an independent steel wire safety rope, which is placed in the middle of the platform 8. It is strictly forbidden to connect the safety rope to the aforementioned fixed component 4, other suspension mechanisms, or other non-main structure. The safety rope is generally connected to the main structure of the building, ensuring the stability of the connection point. The self-locking device is directly installed on the safety rope. During construction, workers inside the suspended platform 8 must attach their safety belts to the self-locking device on the safety rope and must comply with the following construction requirements: "Attach the safety belt to the self-locking device on the safety rope before entering the platform; the safety belt must remain attached to the self-locking device on the safety rope throughout the construction process; and remove the safety belt from the self-locking device after exiting the platform."
[0115] After the entire installation process is completed, the suspended platform 8 and its installation structure need to be debugged. Specifically, the cable is connected to the secondary electrical control box and then to the main power supply provided by the construction site. A jog test is then performed. Next, the wire rope 3 is installed into the hoist and safety lock, and the suspended platform is moved up and down once, reaching a height of approximately 3 meters. Finally, the installation of each connection point is checked again.
[0116] The equipment must be tested before each use. Only after testing confirms that all parts of the equipment are in normal working order can it be put into operation. The testing of the suspended platform 8 includes the following aspects:
[0117] Adjust the suspended platform 8 to a horizontal position and start the hoist to raise it to about 1 meter. Switch the selector switch on the electrical control box to one end, causing one end of the platform to descend. When the angle of inclination between the platform and the horizontal ground reaches the safety lock rope angle (≤14°), the safety lock will automatically lock the safety wire rope 3, causing the platform to stop descending immediately. At the same time, check the reliability of the safety lock on the other end.
[0118] With this, the commissioning of suspended platform 8 is complete.
[0119] After the construction of the seven exterior walls is completed, a comprehensive inspection of all suspended platform equipment must be carried out before the suspended platform 8 is dismantled. Any suspended platforms 8 operating with defects must be inspected and repaired in a timely manner. Only after the repairs are completed can the suspended platform 8 be dismantled.
[0120] The steel wire rope 3 of the suspended platform 8 cannot be lowered directly from top to bottom. The steel wire rope 3 needs to be pulled to the closed layer defined by the sloping roof structural slab 1, bundled from the closed layer, and finally hoisted downstairs.
[0121] All objects removed from the suspended platform 8 must not be thrown from above. Before removing the suspended platform 8, a safe area must be demarcated below and cordoned off with warning lines.
[0122] When dismantling the suspended platform 8, the safety management personnel of the dismantling unit and the general contractor must be on-site to ensure that the dismantling operation is carried out strictly in accordance with the construction sequence.
[0123] At this point, the entire process of installing, debugging, and dismantling the suspended platform 8 is complete.
