The scaffolding includes two structural units, each comprising: a fixed pole; a telescopic pole fixedly connected to the fixed pole; a top wheel structure rotatably connected to the bottom of the telescopic pole; a guard rod rotatably connected at its middle section to the top of the second end of each telescopic pole; and a side wheel structure fixedly connected to the guard rod. In the working state, the first wheel is in contact with the top of the beam, and the second wheel is in contact with the side wall of the beam.

The scaffolding as a whole can be moved, and the guard rods, when locked and unfolded, form a rigid guardrail, achieving continuous coverage of the construction point. The folded state effectively reduces the transport volume and facilitates hoisting.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of scaffolding, in particular to a folding anti-toppling scaffold and a bent cap construction application method. BACKGROUND

[0002] Current anti-toppling scaffolds mainly adopt two technical routes to improve stability:

[0003] The ground area adjustment scheme increases the ground area by adding an expansion support leg or an adjustable foot at the bottom, which can significantly reduce the risk of overturning when the support range is sufficient;

[0004] The counterweight loading scheme sets a counterweight structure at the key position to optimize the center of gravity distribution and achieve the anti-toppling goal by increasing the anti-overturning moment.

[0005] However, in the construction of the top of the beam structure, special working conditions are faced, specifically, the construction operation surface is narrow and long, and the typical width is often less than 2 meters, which makes the scaffold installation space extremely limited; during the construction process, continuous displacement operation is required along the beam to cover multiple construction points, and the scaffold is required to have the ability to move without disassembly.

[0006] The existing scheme has problems such as insufficient support structure expansion space, time-consuming and laborious counterweight loading and unloading, and cannot meet the requirements of narrow space adaptability and flexible movement, which makes it difficult to be effectively applied. SUMMARY

[0007] The present application provides a folding anti-toppling scaffold and a bent cap construction application method, which can effectively solve the problems in the background art.

[0008] In order to achieve the above purpose, the technical scheme adopted by the present application is:

[0009] A folding anti-toppling scaffold, comprising two structural units arranged symmetrically and connected at the top, when rotated to the working state, the two structural units are locked in angle by a fixed structure, the structural unit comprises:

[0010] A fixed rod body;

[0011] At least three telescopic rod bodies distributed along the length direction of the fixed rod body, the first end of the telescopic rod body is fixedly connected with the fixed rod body;

[0012] A top wheel structure, at least two telescopic rod bodies on both sides of the distribution direction are correspondingly connected at the bottom, comprising a first fixed seat and a first wheel body connected by a rotating shaft, the first fixed seat is connected with the telescopic rod body, and when rotated to the working state, the angle is locked by a first locking structure;

[0013] The guard rod is rotatably connected to the top of the second end of each of the telescopic rods in the middle, and when rotated to the working state, the angle is locked by the second locking structure. The upper part of each of the guard rods is connected by the rod body or steel wire structure to form a guardrail.

[0014] The side wheel structure is fixedly connected to at least two of the guard rods on both sides of the distribution direction, including a second fixed seat and a second wheel body rotatably connected by a rotating shaft. The second fixed seat is fixedly connected to the guard rod, and the connection position is located below the middle of the guard rod.

[0015] In operation, the first wheel is in contact with the top of the beam, and the second wheel is in contact with the side wall of the beam. Both the first wheel and the second wheel are rolled along the length of the beam.

[0016] Furthermore, in the operating state, the telescopic length of each segment of the telescopic rod is fixed.

[0017] Furthermore, the telescopic rod includes a telescopically configured first segment and a second segment, wherein the first segment is fixedly connected to the fixed rod.

[0018] The structural unit further includes at least one elastic structure corresponding to one of the telescopic rods, the elastic structure comprising:

[0019] Two connecting seats are fixedly connected to the first segment and the second segment, respectively;

[0020] The spring has its two ends connected to the two connecting seats respectively, and the extension length of the first segment and the second segment is maintained by the spring.

[0021] Furthermore, the telescopic rod is fixedly connected to the top of the fixed rod;

[0022] The two structural units are rotatably connected by a hinge structure that is connected to the top of the telescopic rod.

[0023] Furthermore, the fixing structure connects the two fixing rods to lock the telescopic rods in the two structural units at a 180-degree angle.

[0024] Furthermore, the first locking structure is an angle steel structure, which is connected to the first fixed seat and the telescopic rod respectively to lock the angle between the first fixed seat and the telescopic rod.

[0025] Furthermore, the second locking structure is an angle steel structure, which is connected to the protective rod and the telescopic rod respectively to lock the angle between the protective rod and the telescopic rod.

[0026] Furthermore, the lower part of each of the protective rods is connected by a rod body or steel wire structure.

[0027] Furthermore, the protective rod includes a telescopically configured top segment and a bottom segment. The bottom segment is rotatably connected to the telescopic rod body. The top segment is telescopically sleeved inside the bottom segment. The extension length is determined by the compression of the top segment by a bolt that passes through the bottom segment and is threadedly connected to the bottom segment.

[0028] A method for constructing the cap beam of a folding anti-tipping scaffold as described above includes:

[0029] Rotate each of the protective rods until they are in contact with the telescopic rod body, while maintaining the telescopic length of the telescopic rod body;

[0030] The top wheel structure is locked in the working state relative to the telescopic rod.

[0031] First lifting points are determined at the second ends of at least four symmetrically distributed telescopic rods, and the rods are lifted by slings, with an acute angle between the telescopic rods of the two structural units in the lifting state;

[0032] The connecting area in the middle of the two structural units of the scaffold and each of the top wheel structures are placed on top of the beam to obtain support;

[0033] The protective rod is locked in the working state relative to the telescopic rod body;

[0034] Disconnect the sling from the first lifting point, establish a second lifting point between the sling and the two fixed rods, and perform a second lifting operation;

[0035] Once the set lifting height is reached, the fixing rods of the two structural units are supported by jacks, and the connection is completed.

[0036] The technical solution of this invention can achieve the following technical effects:

[0037] This invention effectively solves the contradiction between anti-tipping and flexible movement of scaffolding in the construction of narrow and long beams through the collaborative design of symmetrical folding structural units and a dual-wheel adaptive system: the side wheel structure applies horizontal pre-tension force close to the beam wall, and the top wheel structure supports the top of the beam to form a self-stabilizing clamping system, eliminating the need for extended support legs or counterweights, and achieving anti-tipping on a working surface within a certain width range; the scaffolding as a whole can roll and move along the length of the beam, and the guardrails, after being locked and unfolded, form a rigid guardrail, achieving continuous coverage of the construction point and eliminating the protective vacuum caused by disassembly and assembly; the folded state effectively reduces the transportation volume and facilitates hoisting, and the working form can be quickly unfolded on site by rotating and locking, greatly reducing the risk of high-altitude assembly.

[0057] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0058] like Figures 1 to 15 As shown, a folding anti-tipping scaffold includes two symmetrically arranged structural units 10 rotatably connected at the top. When rotated to the working state, the two structural units 10 lock their angle through a fixing structure. The structural unit 10 includes:

[0059] Fixed rod 01 serves as the installation base for subsequent structures;

[0060] At least three telescopic rods 02 are distributed along the length of the fixed rod 01, and the first end 021 of the telescopic rod 02 is fixedly connected to the fixed rod 01; in this embodiment, four telescopic rods 02 are used as an example. Figure 5 and 6 The connection state of the telescopic rod 02 and the fixed rod 01 is shown. Of course, the number and distribution density of the telescopic rod 02 can be set according to the actual working conditions. Three or five or more rods are also within the protection scope of this invention.

[0061] The top wheel structure 03 is rotatably connected to the bottom of at least two telescopic rods 02 on both sides of the distribution direction. It includes a first fixed seat 031 and a first wheel 032 rotatably connected via a rotating shaft. The first fixed seat 031 is rotatably connected to the telescopic rods 02, and when rotated to the working state, its angle is locked by a first locking structure 033. During operation, the first wheel 032 rotates relative to the first fixed seat 031 via a rotating shaft to achieve rolling relative to the top of the beam 20. In some embodiments of the present invention, the top wheel structure 03 is installed only corresponding to the telescopic rods 02 on both sides of the distribution direction. In other embodiments, in addition to the telescopic rods 02 on both sides of the distribution direction, the top wheel structure 03 can also be installed corresponding to some or all of the telescopic rods 02 located in the middle. The specific choice depends on the structural strength of the top wheel structure 03 and interference with other structures.

[0062] The top wheel structure 03, based on its rotatable connection to the bottom of the telescopic rod 02, can achieve a working state and a storage state, distinct from the working state. Specifically, when the first fixed seat 031 drives the first wheel 032 to rotate to an angle relatively close to the telescopic rod 02, the entire structure achieves a more suitable storage state, which is suitable for transportation, etc. Figure 7 and Figure 8 This demonstrates a specific implementation using a rod structure as the first fixed seat 031. In this mode, the working state refers to the rod structure serving as the first fixed seat 031 being perpendicular to the telescopic rod 02.

[0063] The guardrail 04 has its middle section 041 rotatably connected to the top of the second end 022 of each telescopic rod 02. When rotated to the working state, the angle is locked by the second locking structure 044. The upper part of each guardrail 04 is connected by a rod body or wire structure 05 to form a guardrail. Figure 7 and Figure 9 As shown, the protective rod 04, based on a steel wire structure 05 and a rotating connection to the top of the telescopic rod 02, can achieve both a working state and a retracted state. Specifically, when the protective rod 04 is rotated to an angle relatively close to the telescopic rod 02, the overall structure achieves a more suitable retracted state, which is suitable for transportation, etc. See also... Figure 7 This demonstrates the vertical state of the protective rod 04 and the telescopic rod 02 in their working condition;

[0064] The side wheel structure 06 is fixedly connected to at least two guard rods 04 on both sides of the distribution direction. It includes a second fixed seat 061 and a second wheel body 062 rotatably connected via a rotating shaft. The second fixed seat 061 is fixedly connected to the guard rod 04, with the connection position located below the middle 041 of the guard rod 04, i.e., on the second side 043. During operation, the second wheel body 062 rotates relative to the second fixed seat 061 via the rotating shaft to achieve rolling relative to the side wall of the beam 20. In some embodiments of the present invention, the side wheel structure 06 is installed only corresponding to the guard rods 04 on both sides of the distribution direction. In other embodiments, in addition to the guard rods 04 on both sides of the distribution direction, the side wheel structure 06 can also be installed corresponding to some or all of the guard rods 04 located in the middle. The specific choice depends on the structural strength of the side wheel structure 06 and interference with other structures.

[0065] In the working state, the first wheel 032 is in contact with the top of the beam 20, and the second wheel 062 is in contact with the side wall of the beam 20. Both the first wheel 032 and the second wheel 062 are rolled along the length of the beam 20.

[0066] This invention effectively solves the contradiction between preventing scaffolding from tipping over and facilitating flexible movement during the construction of narrow and long beams through the coordinated design of symmetrical folding structural units and a dual-wheel adaptive system: the side wheel structure 06 applies horizontal pre-tensioning force close to the beam wall, and the top wheel structure 03 supports the top of the beam to form a self-stabilizing clamping system, eliminating the need for extended support legs or counterweights, and achieving anti-tipping on a working surface within a certain width range; the scaffolding as a whole can roll and move along the length of the beam 20, and the guardrail 04 forms a rigid guardrail after being locked and unfolded, achieving continuous coverage of the construction point and eliminating the protective vacuum caused by disassembly and assembly; the folded state effectively reduces the transportation volume and facilitates hoisting, and the working form can be quickly unfolded on site by rotating and locking, greatly reducing the risk of high-altitude assembly.

[0067] The telescopic pole 02 is adjustable in length to accommodate the width of different beams 20. The guardrail 04 is locked by rotation to form a rigid guardrail. The first side 042 above the middle 041 is connected to the pole or wire structure 05 to form a protective net with adjustable mesh. The device moves as a whole, realizing a continuous operation mode of single installation and full coverage, eliminating the risk of repeated disassembly and assembly.

[0068] In a preferred embodiment of the above-described method, the telescopic length of each segment of the telescopic rod 02 is fixed during operation. In this preferred embodiment, the fixed telescopic length needs to be set according to the dimensions of the beam 20, and the number of telescopic segments of the telescopic rod 02 can be flexibly selected; two, three, or more segments are all feasible in this preferred solution. In this embodiment, the telescopic rod 02 can be specifically configured as a nested structure, and the fixed telescopic length can be achieved by pressing the inner ring structure with bolts that penetrate the outer ring structure and are threadedly connected to it.

[0069] As another preferred embodiment of the above, such as Figure 4 , 5 As shown in Figure 10, the telescopic rod 02 includes a telescopically configured first segment 023 and a second segment 024, with the first segment 023 fixedly connected to the fixed rod 01. The structural unit also includes an elastic structure 07 corresponding to at least one telescopic rod 02. In the embodiment shown in the figure with four telescopic rods 02, the telescopic rods 02 on both sides are connected to the top wheel structure 03. In this embodiment, it is preferable to install the elastic structure 07 corresponding to the two telescopic rods 02 in the middle. Specifically, the elastic structure 07 includes:

[0070] Two connecting seats 071 are fixedly connected to the first segment 023 and the second segment 024 respectively; the spring 072 is connected to the two connecting seats 071 at both ends respectively, and the extension length of the first segment 023 and the second segment 024 is maintained by the spring 072.

[0071] This preferred method achieves different technical effects compared to the rigid maintenance of the telescopic length of the first segment 023 and the second segment 024. Specifically, by using spring 072 to maintain the telescopic length of the first segment 023 and the second segment 024, the length of the telescopic rod 02 can be elastically variable during operation. Of course, it is necessary to control the telescopic length maintenance capability of spring 072 by controlling parameters such as the wire diameter, spring mean diameter, effective number of coils, and elastic modulus. This maintenance capability is at least reflected in the fact that the stiffness of spring 072 provides continuous axial pressure, ensuring that the side wheel structure 06 remains pressed against the side wall of beam 20 when the telescopic rod 02 is working on the top surface of beam 20, thus counteracting loosening caused by construction vibration.

[0072] As a preferred embodiment of the above, such as Figure 6 As shown, the telescopic rod 02 is fixedly connected to the top of the fixed rod 01; the two structural units 10 are rotatably connected by a hinge structure connected to the top of the telescopic rod 02. As a further preferred embodiment, the fixed structure locks the telescopic rods 02 in the two structural units 10 at a 180-degree angle by connecting the two fixed rods 01.

[0073] like Figure 4 As shown, in this preferred embodiment, the fixing structure can be a connecting plate, one end of which is rotatably connected to one of the fixed rods 01 on one side, and the other end, after the telescopic rods 02 on both sides are at a 180-degree angle, is locked to the fixed rod 01 on the other side by bolts. The telescopic rods 02 in the two structural units 10 operate in a 180-degree state, providing a flat surface within the operating space.

[0074] As a preferred embodiment of the above, see Figure 8The first locking structure 033 is an angle steel structure, which is connected to the first fixed seat 031 and the telescopic rod 02 respectively to lock the angle between the first fixed seat 031 and the telescopic rod 02. For the same technical purpose, such as... Figure 9 As shown, the second locking structure 044 is an angle steel structure, which is connected to the protective rod 04 and the telescopic rod 02 respectively to lock the angle between the protective rod 04 and the telescopic rod 02.

[0075] By using angle steel structures as the first locking structure 033 and the second locking structure 044, better cost and stability can be achieved. Stable connection can be achieved simply by ensuring that the two structures to be connected provide two planes that can be set at 90 degrees. Specifically, the angle steel structure can be fixed by bolts.

[0076] As a preferred embodiment, the lower part of each protective rod 04 (041 in the middle section) is connected by a rod body or wire structure 05. Compared to the protective net above the middle section 041, the rod body or wire structure 05 here can improve the overall structural stability of each protective rod 04.

[0077] As a preferred embodiment of the above, see Figure 9 The protective rod 04 includes a telescopic top section and a bottom section. The top section is located on the first side 042, and the bottom section is located on the second side 043. The bottom section is rotatably connected to the telescopic rod body 02. The top section is telescopically sleeved inside the bottom section. The extension length is determined by the compression of the top section by a bolt that passes through the bottom section and is threadedly connected to the bottom section.

[0078] Based on the structure of this preferred embodiment, a better storage and transportation state can be obtained when the top segment is retracted and fixed relative to the bottom segment, and a higher protection height can be obtained when the top segment is extended and fixed relative to the bottom segment.

[0079] like Figures 11 to 15 As shown, as a preferred application method, this embodiment provides the above-described method for constructing the cap beam of the folding anti-tipping scaffold, specifically for the construction of the cap beam support pad, including:

[0080] S1: Rotate each protective rod 04 until it is in contact with the telescopic rod body 02, while maintaining the telescopic rod body 02 at its extended length. See [link to specific details] for the desired state. Figure 11 and Figure 13 ;

[0081] S2: Relative to the telescopic rod 02, lock the top wheel structure 03 in the working state. This step is completed on the ground, which can reduce the difficulty of operation on the top of the cap beam.

[0082] S3: As Figure 12As shown, a first lifting point 30 is determined at the second end 022 of at least four symmetrically distributed telescopic rods 02, and the rods are lifted by slings 40. In the lifting state, the telescopic rods 02 of the two structural units 10 form an acute angle; similarly... Figure 11 and Figure 13 As shown, the acute angle state in this step is illustrated. This state can be naturally achieved by the abutting of the two protective rods 04 on both sides. In a specific embodiment of the present invention, the first suspension point 30 is selected on the four outermost telescopic rods 02.

[0083] S4: Place the connecting area in the middle of the two structural units 10 of the scaffold and each top wheel structure 03 on the top of the beam 20 to obtain support; this step can roughly determine the installation position of the scaffold relative to the cap beam. After obtaining support, it can be provided to the operators for subsequent operations in a relatively stable state.

[0084] S5: Relative to telescopic rod 02, lock protective rod 04 in the working state; such as Figure 14 and 15 As shown, the guard rod 04 is locked. During this process, the connection between the sling 40 and the first lifting point 30 can be maintained, but no upward lifting force needs to be applied; it is only used as an installation protection measure.

[0085] S6: Disconnect the sling 40 from the first lifting point 30, establish the second lifting point 50 between the sling 40 and the two fixed rods 01, and lift for the second time; specifically, the sling 40 can be sleeved around the two fixed rods 01, and the sleeved points can be set at two or more places to achieve stable lifting. During this process, the structural units 10 on both sides can naturally achieve centering relative to the cap beam under the constraint of the side wheel structure 06.

[0086] S7: After reaching the set lifting height, use jacks to support the fixed rods 01 of the two structural units 10 and complete the connection. The set lifting height in this step is based on the fact that the contact relationship between the side wheel structure 06 and the side wall of the cap beam is not broken. After supporting the fixed rods 01 on both sides with jacks, based on the rotational connection at the top, the fixed rods 01 on both sides can reach the same height and fit together. Establishing the connection between the two completes the overall installation of the scaffolding.

[0087] In this application scenario, the symmetrically rotating structural unit 10, in conjunction with the telescopic rod 02 and the dual-wheel system, forms an adaptive clamping structure on the top of the cap beam during operation. The top wheel structure 03 rolls against the top surface of the cap beam to provide support, while the side wheel structure 06 applies horizontal preload force against the side wall of the cap beam, forming a stable structural system that effectively overcomes the installation difficulties on the narrow top surface of the cap beam. Operators can construct the support pad stone based on the space between the telescopic rod 02, the fixed rod 01, and the protective rod 04.

[0088] Of course, the folding anti-tipping scaffolding in this invention can also be applied to the construction of other beam structures that meet the requirements of use, all of which are within the protection scope of this invention.

[0089] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
