Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to auxiliary scaffolding for the erection of steel-concrete composite columns and beams. Background Technology

[0002] In the field of building construction, steel-concrete composite columns and steel-concrete composite beams are widely used due to their superior mechanical properties. Construction of such structures, especially the reinforcement binding, formwork erection, and concrete pouring in the column joint area, typically requires the erection of reliable working platforms or auxiliary support scaffolding around the column.

[0003] Traditional scaffolding has several shortcomings when erecting steel-concrete composite columns and beams. For example, it lacks intuitive and effective methods for ground leveling, making it difficult for workers to accurately judge the flatness of the scaffolding uprights. This leads to uneven stress on the bottom of the scaffolding, easily causing local deformation or even damage, affecting overall stability, and it cannot adapt to the complex and varied uneven ground conditions of construction sites. Furthermore, it is difficult to precisely control the installation depth of the supporting bolts and uprights. Inserting the supporting bolts too deeply or too shallowly will make the installation of the uprights difficult, either failing to achieve the design load-bearing capacity or resulting in insufficient installation torque, posing a safety hazard. In addition, the traditional scaffolding's fixing method for supporting bolts is not stable enough, easily leading to swaying and settlement under large vertical loads, making it difficult to ensure the rigid connection of the scaffolding base nodes. Therefore, auxiliary scaffolding for the erection of steel-concrete composite columns and beams is proposed to solve the problems mentioned above. Summary of the Invention

[0004] To address the shortcomings of existing technologies and improve the scaffolding installation effect, this application provides an auxiliary scaffolding for the construction of steel pipe concrete columns and composite beams, which has advantages such as good installation effect and enhanced structural stability, thus solving the problems mentioned above.

A horizontal connecting plate is hinged to the outside of the base, and a support rod connected to the horizontal connecting plate is hinged to the outside of the support seat. The locking element and the supporting screw are both located outside the supporting screw. The locking element moves with the displacement of the supporting screw, driving the support seat to move downward and realizing the rotation of the horizontal connecting plate through the support rod.

[0008] A clamping structure is provided between the base and the receiving seat. The clamping structure consists of a guide and a locking member, wherein the guide and the locking member abut against each other and abut against the outer surface of the supporting screw by the downward movement of the receiving seat.

[0009] Optional: The sweeping rod consists of a rod body and a buckle, wherein there are two buckles, which are welded to both ends of the rod body and are fixed to two adjacent disc buckles by bolts respectively.

[0010] Optionally: the upright and the pole body are respectively arranged in the X and Y axis directions, the finding plate is arranged parallel to the pole body, the finding plate is installed on the outer surface of the base, and the finding plate has a number of connecting holes inside.

[0011] Optionally: The base includes a bottom sleeve and a top sleeve with a hollow interior. The top sleeve is welded to the top of the bottom sleeve, and both the bottom sleeve and the top sleeve are fitted onto the outer surface of the supporting screw. The leveling plate is fixed to the outer surface of the bottom sleeve.

[0012] Optionally: The horizontal connecting plate is hinged to the outer surface of the base sleeve. The interior of the horizontal connecting plate has several locking holes that are equally distributed and adapted to the connecting holes. The horizontal connecting plate is flipped by the support rod and fits against the upper surface of the finding plate.

[0013] Optionally: A locking tube is welded to the top side of the receiving seat, the guide is located between the receiving seat and the bottom sleeve, and the locking tube is threadedly engaged with the locking member;

[0014] The locking component includes a mounting block and a locking sleeve. The top side of the locking sleeve is fixed to the bottom side of the mounting block. The mounting block is threadedly connected to the supporting screw, and the inner side of the locking sleeve is threadedly engaged with the outer surface of the locking tube.

[0015] Optionally: The guide includes a connecting sleeve sleeved on the outer surface of the supporting screw, a rotary joint rotatably installed between the top side of the connecting sleeve and the bottom side of the receiving seat, a guide sleeve with a conical shape fixed on the bottom side of the connecting sleeve, and a guide slope for cooperating with the locking piece provided on the inner side of the guide sleeve, and a guide rod that abuts against the guide inside the bottom sleeve.

[0016] Optionally: The guide rod consists of a shaft and a ball bearing, the ball bearing being rotatably mounted on the end of the shaft, and the inner side of the guide sleeve having a guide groove adapted to the guide rod, wherein the guide groove is spirally shaped and the ball bearing rolls in contact with the guide groove.

[0017] Optionally: The clip includes an elastic sheet fixed to the top side of the top sleeve, a connector is welded to the top side of the elastic sheet, an installation groove is provided on the inner side of the connector, and a clamp located outside the supporting screw is fixed in the installation groove, and a second guide slope is provided on the outer side of the connector to abut against the first guide slope.

[0018] Optionally: The bottom side of the guide is provided with a buffer member connected to the bottom sleeve. The buffer member includes two receiving rings distributed vertically.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This invention, by rotating the locking member to follow the downward movement of the supporting screw, can simultaneously complete the functions of unfolding the working platform and clamping and locking the supporting screw, combining multiple construction steps and greatly improving the erection efficiency.

[0021] 2. In this invention, the clamping structure forms a wedge self-locking effect through the abutment and cooperation of the guide and the clamp, so that the vertical load borne by the scaffold is further transferred to the guide through the bearing seat, causing it to have a continuous downward pressure. This makes the clamping force of the clamp on the supporting screw increase with the increase of the load, ensuring the rigid connection of the root node of the scaffold and effectively preventing the scaffold from shaking and settling.

[0022] 3. In this invention, the leveling plate is set outside the supporting screw and has several connection holes inside. The leveling plate can provide a flat reference surface for the construction of scaffolding, ensuring the horizontal and verticality of the scaffolding installation. The connection holes facilitate connection and fixation with other components, increasing the flexibility of scaffolding construction.

[0023] 4. In this invention, the buffer spring not only makes the clamping process smooth, but also plays a role in buffering and equalizing force when the structure is under stress. In conjunction with the spiral guide groove and the rolling of the ball, the downward pressure is converted into rotational force, making the clamping action smoother and more uniform.

[0035] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0036] Example 1, such as Figure 1 and Figure 2As shown, this is the first embodiment of the present invention. This embodiment provides an auxiliary scaffold for the construction of steel pipe concrete columns and composite beams. The scaffold consists of a support bolt 11 inserted into the ground, an upright 12 threaded onto the top of the support bolt 11, a disc buckle 15 fixed to the outer surface of the upright 12, and a ground-level bar 13 snapped onto the disc buckle 15. Specifically, the disc buckle 15 has multiple mounting holes arranged in a ring inside for easy connection from all four sides. It should be noted that there are multiple scaffolds 1, and the multiple scaffolds 1 are equidistantly distributed and connected to form the scaffold. A leveling plate 14 is provided on the outside of the support bolt 11. The leveling plate 14 can provide a flat reference surface for the construction of the scaffold, ensuring the horizontal and vertical installation of the scaffold 1.

[0037] To achieve the connection between the sweeping rod 13 and the upright rod 12, such as Figure 2 As shown, the sweeping rod 13 consists of a rod body 131 and two locking buckles 132. The two locking buckles 132 are welded to both ends of the rod body 131 and are fixed to two adjacent disc buckles 15 by bolts, forming a tight and secure connection between the sweeping rod 13 and the upright 12. In the horizontal direction, the sweeping rod 13 effectively transmits horizontal forces, preventing horizontal displacement of the upright 12, further enhancing the overall stability of the scaffolding and ensuring the safe operation of construction workers on the scaffolding.

[0038] In this embodiment, the uprights 12 and the pole body 131 are arranged in the X and Y axis directions, respectively. The leveling plate 14 is arranged parallel to the pole body 131 and is installed on the outer surface of the base 21. The leveling plate 14 has several connecting holes inside. It should be noted that the ground is often uneven on the construction site. The leveling plate 14 can be adjusted and installed according to the actual ground conditions through the several connecting holes inside, so that the bottom of the scaffolding is kept horizontal. This helps to evenly distribute the load borne by the scaffolding, avoid deformation or damage to the scaffolding due to uneven local stress, and improve the stability and service life of the scaffolding.

[0039] It should be noted that, firstly, the supporting bolt 11 is made of high-strength alloy steel, which has high strength and corrosion resistance, and can withstand large tensile and compressive forces, ensuring long-term stable use in complex construction environments; secondly, the upright 12 is made of high-quality carbon structural steel, which has good toughness and machinability, making it easy to perform thread processing and connect with other components; moreover, the disc buckle 15 is made of special alloy material, and after precision casting and heat treatment, it has high strength and wear resistance, ensuring a reliable connection with the ground-level bar 13; to ensure connection stability, the bar body 131 and the locking buckle 132 of the ground-level bar 13 are made of high-strength aluminum alloy, which is lightweight, high-strength, and easy to handle and install; finally, the leveling plate 14 is made of high-strength steel plate with rust-proof surface treatment, which can adapt to different climates and environmental conditions and ensure the flatness of the bottom of the scaffolding.

[0040] Example 2, as Figures 2-9 As shown, this is the second embodiment of the present invention. Unlike embodiment 1, a connecting mechanism 2 is provided above the flat plate 14. The connecting mechanism 2 includes a base 21, a receiving seat 22, and a locking member 23 arranged sequentially from bottom to top. A horizontal connecting plate 24 is hinged to the outside of the base 21, and a support rod 25 connected to the horizontal connecting plate 24 is hinged to the outside of the receiving seat 22. The locking member 23 and the supporting screw 11 are both located outside the supporting screw 11. The locking member 23 follows the displacement of the supporting screw 11, driving the receiving seat 22 to move downwards. The strut 25 enables the rotation of the horizontal connecting plate 24. It should be noted that the flat plate 14 serves as a horizontal reference benchmark, allowing workers to visually observe its horizontal state when inserting the supporting screw 11. This achieves visualization and real-time feedback of ground leveling. At the same time, the locking piece 23 in the connecting mechanism 2 abuts against the receiving seat 22, which is not only a trigger point for action but also indirectly marks the correct installation depth required for the supporting screw 11. This effectively avoids the problem of difficult installation or insufficient load-bearing capacity of the upright 12 caused by the supporting screw 11 being inserted too deeply or too shallowly.

[0041] To further improve the stability of the supporting screw 11, a clamping structure is provided between the base 21 and the receiving seat 22 in this embodiment, such as... Figures 7-9 As shown, the clamping structure consists of a guide 26 and a locking member 29. The guide 26 and the locking member 29 abut against each other and abut against the outer surface of the supporting screw 11 by the downward movement of the receiving seat 22. It should be noted that the clamping structure forms a wedge self-locking effect through the abutment between the guide 26 and the locking member 29. This allows the vertical load borne by the scaffold to be further transferred to the guide 26 through the receiving seat 22, causing it to have a continuous downward pressure. As a result, the clamping force on the supporting screw 11 increases with the increase of the load, ensuring the rigid connection of the scaffold root node and effectively preventing the scaffold from swaying and settling.

[0042] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the base 21 in this embodiment includes a hollow bottom sleeve 211 and a top sleeve 212. The top sleeve 212 is welded to the top of the bottom sleeve 211, and both the bottom sleeve 211 and the top sleeve 212 are fitted onto the outer surface of the supporting screw 11. The leveling plate 14 is fixed to the outer surface of the bottom sleeve 211. Specifically, the horizontal connecting plate 24 is hinged to the outer surface of the bottom sleeve 211. The horizontal connecting plate 24 has several equidistantly distributed locking holes 241 that match the connecting holes. The horizontal connecting plate 24 is flipped by the support rod 25. After rotation, it fits against the upper surface of the leveling plate 14. Furthermore, the locking hole 241 provides multiple options for fixing the horizontal connecting plate 24. Construction personnel can select the appropriate locking hole 241 to match the connecting hole according to the actual situation to fix the horizontal connecting plate 24 in the required position, which increases the accuracy and flexibility of adjustment and can meet the precise requirements for the levelness and stability of the scaffolding in different construction scenarios. At the same time, two adjacent horizontal connecting plates 24 can also be connected by external connecting plates in conjunction with the locking hole 241 to further enhance the installation effect.

[0043] It should be noted that the bottom sleeve 211 and the top sleeve 212 are made of high-strength steel, which has high strength, high toughness and good corrosion resistance, and can withstand large loads and harsh environmental conditions, ensuring the long-term stable use of the base 21; in this embodiment, the number of horizontal connecting plates 24 and support rods 25 is at least two, which can provide balanced thrust and ensure that the horizontal connecting plates 24 unfold into place smoothly, synchronously and without twisting.

[0044] like Figures 3-5 As shown, in this embodiment, a locking tube 221 is welded to the top side of the receiving seat 22, and the guide 26 is located between the receiving seat 22 and the bottom sleeve 211. The locking tube 221 is threadedly engaged with the locking member 23; specifically, as shown... Figure 5 As shown, the locking component 23 includes a mounting block 231 and a locking sleeve 232. The top side of the locking sleeve 232 is fixed to the bottom side of the mounting block 231. The mounting block 231 is threadedly connected to the supporting screw 11, and the inner side of the locking sleeve 232 is threadedly engaged with the outer surface of the locking tube 221. In use, when the locking sleeve 232 is tightened onto the locking tube 221, the two are tightly engaged by the threads, which can eliminate any looseness or shaking of the support seat 22 relative to the locking component 23 in the axial and radial directions. This allows all moving parts such as the support seat 22, guide 26, and locking component 29 to form a rigid whole after the action is completed. The load borne by the scaffold can be stably transmitted through the rigid connection, which greatly improves the node stiffness and overall stability.

[0045] In addition, when the supporting screw 11 moves down, the worker can directly see that the locking piece 23 has descended into place, or feel a significant increase in resistance when rotating the screw, because the threaded locking piece 23 begins to contact the receiving seat 22. Thus, it is possible to determine that the depth meets the requirements without the need for other measuring tools. When the supporting screw 11 is at the correct depth, the locking piece 23 itself occupies part of the length of the thread at the top of the supporting screw 11. Therefore, when the upright 12 is tightened to contact the locking piece 23, it means that the upright 12 itself has also reached the designed installation depth and torque requirements, providing a double verification point for installation completion, effectively avoiding the supporting screw 11 and the upright 12 being installed too shallow or too deep.

[0046] To enable the driver for card 29, such as Figure 7 As shown, in this embodiment, the guide 26 includes a connecting sleeve 261 sleeved on the outer surface of the supporting screw 11. A rotary joint 264 is rotatably installed between the top side of the connecting sleeve 261 and the bottom side of the receiving seat 22. A guide sleeve 262 with a conical shape is fixed to the bottom side of the connecting sleeve 261, and a guide slope 263 for use with the locking piece 29 is provided on the inner side of the guide sleeve 262. A guide rod 28 that abuts against the guide 26 is provided inside the bottom sleeve 211. Specifically, as shown... Figure 7 and Figure 8 As shown, the guide rod 28 consists of a shaft 281 and a ball bearing 282. The ball bearing 282 is rotatably mounted on the end of the shaft 281. A guide groove 265, adapted to the guide rod 28, is provided on the inner side of the guide sleeve 262. The guide groove 265 is spirally shaped, and the ball bearing 282 rolls in contact with the guide groove 265. The length of the guide groove 265 is adapted to the downward movement distance of the guide sleeve 262. When the guide sleeve 262 moves downward, because the ball bearing 282 is engaged in the spiral guide groove 265 inside the guide sleeve 262, according to the spiral principle, the downward pressing motion is forcibly converted into a small-amplitude uniform rotation of the guide member 26 around its axis. This rotational motion allows the guide inclined surface 263 to circumferentially and evenly compress all the clamping parts 29, avoiding the problems of single-point jamming and uneven force caused by machining errors or dirt that may occur on traditional purely straight inclined surfaces.

[0047] To further secure the supporting screw 11, such as Figure 9As shown, the clamp 29 in this embodiment includes an elastic sheet 291 fixed to the top side of the top sleeve 212. A connector 292 is welded to the top side of the elastic sheet 291. An installation groove 295 is provided on the inner side of the connector 292, and a clamp 293 located outside the supporting screw 11 is fixed in the installation groove 295. A guide slope 294 that abuts against the guide slope 263 is provided on the outer side of the connector 292. It should be noted that there are at least two clamps 29. When the guide slope 263 moves downward axially by a unit distance using the rotational motion, a larger radial compression stroke is generated relative to the guide slope 294 of the clamp 29. Thus, a larger closing displacement of the clamp 293 can be achieved with a smaller downward pressure, and the force enhancement effect is more obvious.

[0048] To further explain, after the clamp 293 grips the supporting screw 11, the vertical load transmitted from the scaffold will continuously press down on the guide 26 through the bearing seat 22, and then continuously open the clamp 29 through the inclined surface, which is converted into a larger clamping force. The positive feedback mechanism of load clamping force forms a self-locking mechanism, so that the greater the load, the tighter the grip, which can prevent loosening. In addition, the use of at least two clamps 29 provides a circumferentially distributed clamping force and redundancy backup.

[0049] In addition, the elastic plate 291 can be made of a corrosion-resistant, wear-resistant metal plate material with flexible movement to improve the service life and effect of the elastic plate 291; and the inner side of the clamping surface of the chuck 293 should be provided with a high friction coefficient material or structure: for example, a layer of rubber liner, engineering plastic gasket or copper-based powder metallurgy friction plate vulcanized and bonded, which can greatly increase the friction with the screw surface, prevent relative sliding, and at the same time avoid the metal chuck 293 directly biting the thread or surface anti-corrosion layer of the supporting screw 11. At the same time, the clamping surface should be processed with knurling, grid pattern or serration pattern to further engage the surface of the supporting screw 11, especially after the gasket is worn, it can still provide a certain mechanical interlock.

[0050] To ensure a smoother hugging action, in this embodiment, the bottom side of the guide 26 is provided with a buffer 27 that connects to the bottom sleeve 211, such as... Figure 8 As shown, the buffer 27 includes two vertically distributed receiving rings 271. The two receiving rings 271 are respectively installed on the outer surface of the base sleeve 211 and the bottom side of the connecting sleeve 261. A buffer spring 272 is fixed between the two receiving rings 271. Specifically, during the clamping action, the guide 26 and the base sleeve 211 may experience impact due to relative movement. The buffer spring 272 in the buffer 27 is elastic and can absorb and disperse this impact force when the guide 26 moves downward and contacts the base sleeve 211, avoiding a hard collision and making the movement of the guide 26 more stable and smooth, reducing jamming or shaking caused by impact.

[0051] Combined with appendix Figures 1-9The working principle of the above embodiments is as follows:

[0052] Insert the supporting screw 11 into the ground and observe the horizontal state of the leveling plate 14 to perform preliminary leveling of the scaffold upright 12. As the supporting screw 11 moves downward, the locking piece 23 in the connecting mechanism 2 abuts against the receiving seat 22. The locking piece 23 presses down its internal locking sleeve 232, driving the receiving seat 22, which is threaded with it, to move downward in sync. When the receiving seat 22 moves downward, it drives the support rod 25, which is hinged to it, to move, thereby pushing the horizontal connecting plate 24, which is hinged to the base 21, from a drooping state to a horizontal state and to fit against the upper surface of the leveling plate 14. This not only reminds the workers of the installation depth of the supporting screw 11, but also prevents the supporting screw 11 from being installed too deep or too shallow, and also facilitates the subsequent installation depth of the upright 12.

[0053] When the support seat 22 moves down, it also pushes the guide 26 at its bottom to move down together. The guide slope 263 on the inner side of the guide sleeve 262 presses the guide slope 294 on the clamp 29. Since the guide rod 28 cooperates with the spiral guide groove 265 through the ball 282, the pressing process will force the guide 26 to rotate slightly, making the pressing smoother and more uniform. The elastic piece 291 of the clamp 29 deforms under force, driving the clamp 293 to retract towards the center, thereby tightly holding the support screw 11. Then, the locking sleeve 232 is rotated to make it threadedly connected with the locking tube 221, thereby fixing the connecting mechanism 2. Then, the upright 12 is screwed into the top of the support screw 11. The sweeping rod 13 is installed on the disc buckle 15 of the upright 12 and a stable frame 1 is formed through the rod body 131 and the buckle 132, realizing the construction of the scaffold.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
