Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, specifically to a scaffolding for building construction. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified into external scaffolding and internal scaffolding according to its location, into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to its material, and into pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding according to its structural form. Practice has proven that...

[0003] Currently, scaffolding requires constant adjustment and disassembly based on the height of the building. This means that when one floor is erected, workers need to build the next floor, and so on. Furthermore, traditional scaffolding has fixed dimensions and a fixed height for each floor, making it overly complex to adjust and operate. This affects the efficiency of building construction and increases the workload of workers. Therefore, a new type of scaffolding for building construction is proposed to solve the aforementioned problems. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please see Figures 1-8 A scaffold for building construction includes a support frame 1; a work frame 2; and a lifting component 3 for adjusting the height of the work frame 2. The work frame 2 is mounted on the support frame 1. The lifting component 3 includes a drive component and a lifting component.

[0031] In this embodiment, the driving component includes a pressing frame 301, on which a sliding connecting rod 304 is slidably connected. The top of the sliding connecting rod 304 is connected to the working frame 2. A compression spring 305 is provided below the pressing frame 301 and is sleeved on the sliding connecting rod 304. A hook 302 is rotatably connected to the side of the pressing frame 301. The hook 302 is connected to the pressing frame 301 via a torsion spring and is connected to a lifting component. The pressing frame 301 is a horizontally arranged plate-like structure located below the working frame 2 and forming a certain gap with the working frame 2 to facilitate the operator's stepping operation. A sliding connecting rod 304 is provided through the middle area of ​​the pressing frame 301. The sliding connecting rod 304 is a vertically arranged rod-like component, with its bottom slidingly engaged with the pressing frame 301 and its top fixedly connected to the bottom of the working frame 2. The sliding link 304 guides the foot pedal 301 as it moves up and down, ensuring that the foot pedal 301 maintains a stable vertical movement trajectory. A compression spring 305 is located below the foot pedal 301. This compression spring 305 is sleeved on the outside of the sliding link 304, with its upper end abutting against the bottom of the foot pedal 301 and its lower end abutting against a limiting part at the lower end of the sliding link 304 or a limiting plate fixed to the support structure. In its natural state, the compression spring 305 maintains a certain preload, pushing the foot pedal 301 downwards to reset. Simultaneously, it generates a reverse elastic force when the operator applies foot pressure, thus forming the basis for reciprocating motion. When the operator steps on the pressing frame 301 during construction, the pressing frame 301 moves downward against the elastic force of the compression spring 305, causing the sliding connecting rod 304 to slide relative to the work frame 2. At the same time, the hook 302 rotates to a vertical position under the action of the abutment plate 303 and engages with the pull post 307 on the chain 306, forming a linkage structure. When the pressing pressure is released, the compression spring 305 drives the pressing frame 301 to reset, and the hook 302 disengages from the pull post 307 under the action of the torsion spring, thereby realizing the automatic reset and cyclic operation of the driving component.

[0032] Furthermore, the lifting component includes an upper sprocket 308 and a lower sprocket 309, both of which are rotatably connected to the support frame 1. The upper sprocket 308 is connected to the lower sprocket 309 via a chain 306. Multiple pull posts 307 are connected to the side of the chain 306, and abutment plates 303 abut against the side of the hook 302. The abutment plates 303 are fixed to the work frame 2. When the pressing frame 301 is pressed down by gravity, the control hook 302 engages with the pull posts 307 on both sides of the chain 306, thereby driving the chain 306 to rotate. Multiple pull posts 307 are evenly fixed along the length of both sides of the chain 306. The pull posts 307 are columnar protrusions extending outwards from the chain 306 to engage with the hooks 302. The spacing of the pull posts 307 is adapted to the engaging action of the hooks 302, ensuring that the hooks 302 can accurately engage with the pull posts 307 during each pressing operation. Multiple pull posts 307 are evenly fixed along the length of both sides of the chain 306. Each pull post 307 is a columnar protrusion extending outwards from the chain 306 to engage with the hooks 302. The spacing of the pull posts 307 is adapted to the engaging action of the hooks 302, ensuring that the hooks 302 can accurately engage with the pull posts 307 during each pressing operation. When the operator applies a pressing force to the pressing frame 301 on the work frame 2, the pressing frame 301 slides downwards, causing the hooks 302 to move downwards synchronously. During the downward movement, the side of hook 302 first contacts the abutment plate 303 and gradually rotates to a vertical position under the guidance of the abutment plate 303. At this time, the front end of hook 302 engages between two adjacent pull posts 307 on the side of chain 306, forming a locking connection. As the pressure is continuously applied, the foot pedal 301 continues to move downward, driving chain 306 to rotate clockwise or counterclockwise through the engagement of hook 302 and pull posts 307. The transmission of chain 306 then drives upper sprocket 308 and lower sprocket 309 to rotate synchronously, realizing the transmission of power and the change of direction. When the operator releases the pressure, compression spring 305 drives foot pedal 301 to return to its original position, and hook 302 rises accordingly. During the rising process, hook 302 disengages from pull posts 307 and automatically returns to its initial tilted state under the action of torsion spring, preparing for the next foot pedal operation. The chain 306 stops transmitting power after the hook 302 is disengaged. However, since its other side is connected to the uppermost sleeve of the telescopic frame 102 via the bracket 4, the transmission state of the chain 306 directly affects the telescopic height of the telescopic frame 102.

[0033] Furthermore, the support frame 1 includes an upright frame 101, on which a telescopic frame 102 is connected. The telescopic frame 102 is composed of multiple sleeves of different diameters, with a limiting sleeve 104 connected to the uppermost sleeve. The limiting sleeve 104 is slidably connected to the upright frame 101 via a ring. A hook 310 is provided on the upright frame 101. The telescopic frame 102, a telescopic support structure, is composed of multiple sleeves of different diameters coaxially fitted together. Adjacent sleeves can slide relative to each other, thereby adjusting the overall height of the telescopic frame 102. Specifically, the telescopic frame 102 includes at least three sleeve sections, fitted sequentially from the outside to the inside. The bottom of the outermost sleeve is fixed to the bottom of the upright frame 101 or the ground support position, while the innermost sleeve is the top sleeve, which can extend upwards under driving force to lift the working frame 2. A limiting sleeve 104 is fixedly connected to the top of the uppermost sleeve. This limiting sleeve 104 is a ring-shaped structure and is fitted onto the outside of the uppermost sleeve. The limiting sleeve 104 is slidably connected to the upright frame 101 via a ring. Multiple guide rings are fixedly provided on the outer side of the limiting sleeve 104. These rings are fitted onto the vertical guide rods of the upright frame 101, allowing the limiting sleeve 104 to slide smoothly along the vertical direction of the upright frame 101. This sliding connection structure not only guides the lifting and lowering movement of the telescopic frame 102, preventing it from tilting or swaying, but also limits the extension height of the telescopic frame 102, avoiding excessive extension that could lead to structural instability. Multiple hooks 310 are provided on the inner or front side wall of the upright frame 101. These hooks 310 are spaced apart along the height direction of the upright frame 101 and are used to support the downward pressure rods 106 on the telescopic frame 102, thereby achieving gravity support for the working frame 2 at different height positions.

[0034] In addition, two sets of support frames 1 are provided, and the two sets of support frames 1 are symmetrically arranged on the left and right. The working frame 2 is located between the two support frames 1, and the two support frames 1 are connected by fasteners 103. The other side of the chain 306 is connected to the bracket 4, and the other side of the bracket 4 is connected to the uppermost sleeve of the telescopic frame 102. The upper sprocket 308 and the lower sprocket 309 are rotatably connected to the upright frame 101. The working frame 2 is located between the two sets of support frames 1, and its two ends are respectively connected to the lower pressure rods 106 on the two side support frames 1, forming a bridge-type load-bearing structure. The bottom of the working frame 2 is fixedly connected to the top of the sliding connecting rod 304 to ensure that it moves synchronously with the two side support frames 1 during the lifting process. The two sets of support frames 1 are connected to each other by fasteners 103. The fasteners 103 are preferably horizontally arranged connecting rods, and their two ends are respectively fixedly connected to the upper and / or lower parts of the two side upright frames 101. The fastener 103 not only connects the two sets of support frames 1 to form an integral frame structure, but also serves as a tensile support. When the scaffolding is under load, it effectively disperses stress, preventing relative displacement or tilting of the two support frames 1, thereby further improving the overall stability and operational safety of the scaffolding. The chain 306 is a closed loop structure, with its two sides connected to the transmission structure of the lifting component and the telescopic frame 102, respectively. One side of the chain 306 has multiple pull posts 307 for engaging with hooks 302; the other side of the chain 306 is fixedly connected to a bracket 4, a rigid connecting component. One end of the bracket 4 is fixedly connected to a link of the chain 306, and the other end is fixedly connected to the uppermost sleeve of the telescopic frame 102. Through this connection method, when the chain 306 is driven by the hook 302, its motion is directly transmitted to the uppermost sleeve of the telescopic frame 102, thereby driving the entire telescopic frame 102 to extend and retract. The upper sprocket 308 and the lower sprocket 309 are rotatably connected to the upright 101 via bearings or pins. Specifically, the upper sprocket 308 is mounted on the upper part of the upright 101, and the lower sprocket 309 is mounted on the lower part of the upright 101, with both arranged vertically aligned. The rotation axes of both the upper sprocket 308 and the lower sprocket 309 are horizontally positioned to ensure that the chain 306 can run smoothly around them. A lubrication structure or wear-resistant bushing is provided at the connection between the sprockets and the upright 101 to reduce frictional resistance and ensure smooth transmission.

[0035] In addition, the uppermost sleeve of the telescopic frame 102 is connected to an upper pressure rod 105 and a lower pressure rod 106. The work frame 2 is snapped onto the lower pressure rod 106, which is connected to a hook 310. The hook 310 includes a support column 3101, on which a hook column 3102 is fixedly connected. The lower pressure rod 106 overlaps the hook column 3102. The upper pressure rod 105 is fixedly connected to the upper part of the uppermost sleeve. Its main function is to cooperate with the limiting sleeve 104 or other guide structures during the lifting and lowering of the telescopic frame 102 to ensure that the telescopic frame 102 maintains a vertical lifting trajectory. The lower pressure rod 106 is fixedly connected to the lower part of the uppermost sleeve, with both ends extending outward to support the weight of the work frame 2 and to cooperate with the hook 310 to achieve height locking. The work frame 2 is a plate-shaped or grid-shaped standing platform with snap-fit ​​structures at both ends. These snap-fit ​​structures are preferably downward-opening slots or hooks. The work frame 2 is secured to the lower pressure rods 106 on both side support frames 1 via snap-fit ​​structures at both ends, forming a detachable connection. When the telescopic frame 102 rises and falls, the lower pressure rods 106 move up and down accordingly, thereby driving the work frame 2 to rise and fall synchronously. This snap-fit ​​structure facilitates the installation and disassembly of the work frame 2 and maintains the relative position stability between the work frame 2 and the lower pressure rods 106 during the lifting process. After the lower pressure rods 106 are raised to the corresponding height, their ends overlap the hook posts 3102 of the hooks 310 on both sides. Specifically, when the telescopic frame 102 drives the lower pressure rods 106 to the height of a certain hook post 310, the end of the lower pressure rod 106 first contacts the hook post 3102 and rests stably on top of the hook post 3102 under the action of gravity. The inclined design of the hook post 3102 helps guide the lower pressure rods 106 into the support position while preventing them from accidentally slipping off under force, ensuring the reliability of the connection.

[0036] It is worth noting that two sets of hooks 310 are provided, and multiple hooks 310 are arranged longitudinally at equal intervals in both sets. These multiple hooks 310 are used to support the weight of the work frame 2 at different heights. Each hook 310 also includes two sleeves 3104 mounted on the upright 101, with internal rotating grooves 3105 in each sleeve. A rotating key 3103 is fixedly mounted on the support column 3101, and the rotating key 3103 is rotatably connected to the rotating groove 3105. The two sets of hooks 310 are respectively installed on the left and right uprights 101, forming a symmetrical support structure. Multiple hooks 310 are arranged longitudinally at equal intervals along the height direction of the upright 101; that is, on the same upright 101, multiple hooks 310 are arranged sequentially from top to bottom at fixed intervals. This equidistant arrangement allows the work frame 2 to obtain stable support at multiple different height positions, meeting the needs of different construction heights during the building construction process. Multiple hooks 310 are used to support the weight of the work frame 2 at different heights. When the telescopic frame 102 lifts the work frame 2 to a certain height, the end of the lower pressure rod 106 will engage with the hook 310 at the corresponding height, transferring the weight of the work frame 2 and the operator on it to the upright frame 101, thus achieving stable locking of the work frame 2. By setting multiple equally spaced hooks 310, the work frame 2 can achieve stepped height adjustment. Each time the distance between hooks 310 is increased, a new stable working height can be obtained, thereby adapting to the needs of layer-by-layer construction during the building construction process. The hooks 310 also include two sleeves 3104 set on the upright frame 101. These two sleeves 3104 are block-shaped or sleeve-shaped components fixedly installed inside the upright frame 101, and are arranged vertically opposite each other, forming a certain gap between them. Each of the two retaining sleeves 3104 has a rotating groove 3105 inside. This rotating groove 3105 is a recessed, groove-shaped space within the retaining sleeve 3104, preferably a non-circular C-shaped or arc-shaped groove, used to accommodate and guide the rotation of the supporting column 3101. The supporting column 3101 is a vertically arranged columnar member, with its upper and lower ends correspondingly inserted into the upper and lower retaining sleeves 3104. A rotating key 3103 is fixedly mounted on the supporting column 3101. This rotating key 3103 is a key-shaped structure protruding outward from the side of the supporting column 3101, and its shape is adapted to the rotating groove 3105. The rotating key 3103 is embedded in the rotating groove 3105 and can rotate a certain angle within the rotating groove 3105 around the axis of the supporting column 3101. The rotating key 3103 is rotatably connected to the rotating groove 3105, forming a rotatable connection structure. This design allows the supporting column 3101 and its hook column 3102 to rotate relative to the upright frame 101 when subjected to external forces. Specifically, when the upper pressure rod 105 interferes with the hook column 3102 during its ascent, the upper pressure rod 105 will push the hook column 3102, causing the supporting column 3101 to rotate, thus allowing the hook column 3102 to clear the upward path of the upper pressure rod 105 and avoiding structural interference.After the upper pressure rod 105 passes, under the action of the torsion spring or gravity, the bearing column 3101 rotates in the opposite direction to reset, so that the hook column 3102 returns to the inclined support state, ready to receive the lower pressure rod 106.

[0037] Working principle: First, when using the scaffolding, each support frame 1 needs to be assembled. The scaffolding is composed of two support frames 1 joined together. After assembly, the working frame 2 is at its lowest point because its two ends overlap with two downward pressure rods 106. At this time, the telescopic frame 102 is in a retracted state, so the two downward pressure rods 106 are at their lowest position. Then, when it is necessary to increase the overall height of the scaffolding, the operator needs to step down from the middle of the working frame 2, controlling the pressing frame 301 to slide downwards. As the pressing frame 301 moves downwards, it will cause the two hooks 302 to move downwards, and the two hooks 302 will slide against the abutment plate 303, controlling the hooks 302 to change from an inclined state to a tilted state. In the vertical position, the hook 302 engages with the pull posts 307 on both sides of the chain 306. After applying a continuous downward stepping force, the hook 302 moves the pull posts 307 downwards, which in turn drives the chain 306 to transmit power. This is achieved through a cyclic transmission using two sprockets. As the right side of the chain 306 moves downwards, the other side moves upwards. The other side of the chain 306 is connected to the telescopic frame 102 via the bracket 4, thus simultaneously extending the telescopic frame 102. When the telescopic frame 102 extends, it drives the upper pressure rod 105 and lower pressure rod 106 upwards. The entire work frame 2 rests on the lower pressure rod 106. The upward movement of the telescopic frame 102, moving the lower pressure rod 106, simultaneously drives the work frame 2 upwards. Therefore, the operator can now autonomously adjust the scaffolding on the work frame 2. The entire process requires no electrical controls, making it convenient, reliable, and cost-effective. Considering that the work frame 2 bears the weight of the operator, the principle of the autonomous step-up mechanism is as follows: when the operator presses their foot on the stepping frame 301, the operator's weight is borne by the stepping frame 301. In this instantaneous state, the work frame 2 does not bear any weight, or bears very little weight. During the upward movement of the work frame 2, the sliding link 304 will move upward simultaneously. The upward movement of the sliding link 304 will then compress the compression spring 305 in the opposite direction. The compression spring 305 will bear the compressive force in two directions: one is the indirect weight of the operator, and the other is the reverse lifting force generated by the chain 306. After the work frame 2 is raised to a certain height, the lower pressure rod 106 will be locked onto the upper hook 310. The two inclined hooks 3102 will bear the pressure of the lower pressure rod 106, so the operator can stand stably on the work frame 2. Finally, the work frame can be raised autonomously in a stepped manner, which facilitates the operator's house construction.The tilt angle hook 302 is designed to use the elastic force of the torsion spring to control the hook 302 and the pull post 307 on the chain 306 to make way when the hook 302 moves up and resets. This is because to lift to different heights, it is necessary to step on the pressing frame 301 in sequence to change the pressure and achieve a stepped lifting. The purpose of the rotating groove 3105 is to make way for the interference between the upper pressure rod 105 and the hook column 3102 when the upper pressure rod 105 is raised. When the upper pressure rod 105 moves upward, the tilted hook column 3102 will definitely interfere with it. Therefore, the rotating groove 3105 is set up. When it interferes with it, it will drive the hook column 3102 and the support column 3101 to rotate and make way. The rotating key 3103 on the support column 3101 rotates in the rotating groove 3105. The rotating groove 3105 is not a circular groove, but a C-shaped groove. When the upper pressure rod 105 moves up onto the hook column 3102, the hook column 3102 is no longer obstructed. So, using the elastic force of the torsion spring, it tilts again and forms a tree branch shape. Then the upper pressure rod 105 will overlap the hook column 3102. The C-shaped rotating groove 3105 will restrict the support column 3101 to a fixed angle, and finally achieve support.
