Description

Technical Field

[0001] This application relates to the field of scaffolding technology, and in particular to a construction site scaffolding and a method for erecting scaffolding. Background Technology

[0002] In construction sites, external wall operating platforms are often constructed using scaffolding made of steel pipes and their connecting components.

[0003] The related technology discloses a scaffolding structure and scaffolding erection process, including a scaffolding frame. The scaffolding frame includes uprights, main horizontal bars and secondary horizontal bars fixedly connected to the uprights by fasteners; several support bars are provided between two adjacent secondary horizontal bars, and the support bars are fixedly connected to the upper part of the main horizontal bars; the scaffolding frame also includes a scaffold board, and connecting rods are slidably connected to the bottom of the scaffold board and on both sides of it along the width direction of the scaffold board. Each connecting rod has a first locking ring and a second locking ring rotatably connected to one end away from the scaffold board; a gap for inserting the main horizontal bar is opened between the first locking ring and the second locking ring, and a locking bolt for fixing the first locking ring and the second locking ring is connected between them.

[0004] While the aforementioned technologies have achieved the effect of strengthening the connection between the scaffold boards and the scaffolding, in actual installation, each horizontal bar needs to be installed and spliced ​​together individually during scaffolding erection. Furthermore, to ensure the installation accuracy of each horizontal bar, operators need to constantly measure and adjust, resulting in low installation efficiency. Summary of the Invention

[0005] To address the technical problem of low efficiency in the installation and splicing process of scaffolding, the present invention aims to provide a construction site scaffolding and a method for erecting scaffolding.

[0006] First aspect

[0007] This application provides a construction site scaffold, comprising:

[0008] The base is installed on the construction surface;

[0009] A clamping assembly is mounted on the base and fixedly connected to the base; the clamping assembly has multiple pairs of arc-shaped grooves, which can close to form positioning holes.

[0010] Multiple columns are inserted into the positioning holes, and the clamping assembly is used to clamp the multiple columns simultaneously.

[0011] Multiple four-way connectors are sleeved on the column, and each four-way connector has an elastic element inside its connector.

[0012] Multiple connecting rods, the ends of which are inserted into the four-way connector and abut against the elastic element.

[0013] By adopting the above technical solution, the uprights are initially positioned by inserting them into pairs of partially closed arc-shaped grooves. Then, the arc-shaped grooves of the clamping assembly simultaneously clamp and fix the uprights, achieving longitudinal fixation. Multiple connecting rods have one end engaged with a four-way connector, abutting against an elastic element, and the other end engaged with another four-way connector. After assembling multiple connecting rods, the lateral installation and fixation of multiple uprights is completed. During the installation and fixation of the uprights, the clamping assembly allows for initial positioning through the partially closed arc-shaped grooves. Then, closing the arc-shaped grooves together achieves the final fixation of the uprights. Combining the positioning and installation of the uprights into a single process significantly reduces installation time and costs, thus achieving highly efficient scaffolding installation.

[0014] Optionally, a bearing is fixedly connected to the base, and the clamping assembly includes:

[0015] Multiple first-stage clamps;

[0016] A lead screw, one end of which is rotatably connected to the bearing, the lead screw includes a threaded section and a smooth section, the threaded section and the smooth section are spaced apart, a limit ring is provided on the smooth section, the smooth section rotates on the first clamping plate, and the limit ring abuts against the first clamping plate;

[0017] Multiple second clamping plates are provided, with arc-shaped grooves formed on the first clamping plate and the second clamping plates. The lead screw passes through the second clamping plate, and the threaded section is threadedly connected to the second clamping plate. Rotating the lead screw can cause the second clamping plate to move closer to or away from the first clamping plate.

[0018] By adopting the above technical solution, multiple arc-shaped grooves are formed on the first clamping plate. The unclosed arc-shaped grooves provide initial longitudinal positioning for the column. The lead screw adopts a structure of threaded section and smooth section. When the lead screw rotates, it drives the second clamping plate on the threaded section to move closer to the first clamping plate. Since the limiting ring abuts against the first clamping plate, it clamps the first clamping plate located between the limiting ring and the second clamping plate, closing the arc-shaped groove between the clamping plates to clamp the column, thus achieving longitudinal fixation of the column. By utilizing the rotation mechanism of the lead screw and forming threaded and smooth sections on it, in conjunction with the first clamping plate, the second clamping plate, and the limiting ring, longitudinal positioning and clamping fixation of the column are achieved, improving the installation efficiency of the scaffolding.

[0019] Optional, also includes:

[0020] Multiple diagonal braces are provided, and the diagonal braces are detachably connected to the adjacent uprights.

[0021] By employing the aforementioned technical solutions, diagonal bracing can provide additional support and stability to scaffolding. It transfers vertical loads to the ground, reducing bending and stress on connecting rods and columns, and minimizing the risk of lateral tilting and leaning of the scaffolding structure. Furthermore, diagonal bracing provides lateral support to the scaffolding structure. When facing crosswinds or other external forces, diagonal bracing increases the scaffolding's resistance, preventing structural tilting or collapse, and improving the load-bearing capacity and overall structural stability of the scaffolding.

[0022] Optionally, the four-way connector is provided with multiple fixing ears, which are disposed between adjacent connectors, and the diagonal brace includes:

[0023] A diagonal bar, wherein threaded holes are provided axially at both ends of the diagonal bar;

[0024] The first bolt, the shank of the first bolt engaging with the threaded hole;

[0025] The hook has an end that can be rotatably mounted to the head of the bolt, and the hook engages with the fixing lug.

[0026] By adopting the above technical solution, the diagonal brace is installed onto the fixing lug of the adjacent four-way connector using a snap hook. The length of the diagonal brace is adjusted by rotating the first bolt. Depending on the actual needs, when the snap hook is placed on the adjacent fixing lug, rotating the first bolt loosens the connection between the first bolt and the diagonal brace, stretching the diagonal brace to an appropriate length for easy installation. When it is necessary to tighten the connection between the diagonal brace and the fixing lug, rotating the first bolt in the opposite direction retracts the diagonal brace to an appropriate length, connecting and securing the two together, thus achieving the effect of easy installation of the diagonal brace.

[0027] Optional, also includes:

[0028] A scaffold board, which is installed at the end of the column away from the base.

[0029] By adopting the above technical solution, the scaffold boards are used to support the feet and provide a working platform for operators, enabling them to stand or move on the scaffold to perform operations, thereby improving work efficiency and personnel safety.

[0030] Optional, also includes:

[0031] Multiple adjusting rods are installed on the base. The adjusting rods are arranged parallel to the column. The adjusting rods have strip grooves along the height direction. The scaffold board is slidably connected to the adjusting rods. The scaffold board has threaded blind holes that communicate with the strip grooves. The scaffold board also has multiple limiting holes. The column is slidably engaged with the limiting holes.

[0032] The second bolt passes through the groove and is threaded into the blind hole. The second bolt is used to fix the adjusting rod to the scaffold board.

[0033] By adopting the above technical solution, the scaffold plank not only provides a working platform for operators but also limits the movement of vertical columns. The scaffold plank is slidably connected to the adjusting rod on the base, allowing adjustment of the scaffold plank's height relative to the base. Furthermore, limit holes are provided on the scaffold plank. When fixing the columns, the bottom columns can be clamped and fixed by the clamping components, but the columns farther from the base may tilt due to gravity or wind. The limit holes prevent this tilting, thus avoiding vertical deviation and ensuring installation quality.

[0034] Optionally, the elastic element includes:

[0035] A spring, which is fixedly connected to the four-way connector;

[0036] An abutment plate is installed inside the four-way connector and fixedly connected to the four-way connector.

[0037] By adopting the above technical solution, the spring provides a certain elastic buffering effect, absorbing some external forces and vibrations during construction, effectively reducing the impact and damage to the column and connecting rod under external forces. At the same time, the spring maintains a certain tension to ensure a stable connection. The abutment plate, as the medium connecting the spring and the four-way connector, serves to fix the spring and prevent it from falling off. Furthermore, the use of elastic components makes the installation and fixing of the column and connecting rod more convenient and quick, eliminating cumbersome adjustment and fixing steps, and reducing installation time and labor costs.

[0038] Optional, also includes:

[0039] A lifting ladder, one end of which is mounted on the base and the other end of which is mounted on the scaffold board.

[0040] By adopting the above technical solutions, scaffolding is usually used for high-altitude operations, while elevators can conveniently and quickly transport workers from the ground or low places to the scaffolding work platform, reducing the time and labor intensity of climbing up and down, and improving work efficiency.

[0041] Optional, also includes:

[0042] A drive motor is detachably connected to the lead screw, and the drive motor is used to drive the lead screw to rotate.

[0043] By adopting the above technical solution, the traditional method of manually rotating the lead screw requires considerable force and time, wasting labor and time costs. Furthermore, using the lead screw to fasten the clamping plate to fix the column requires ensuring the clamping strength. Using a drive motor can output a larger torque to ensure installation strength while improving the efficiency of installing and fixing the column.

[0044] Second aspect

[0045] This application provides a method for erecting scaffolding on a construction site, for erecting the aforementioned type of scaffolding on a construction site, comprising the following steps:

[0046] S1. Based on the structural construction drawings and the survey of the construction site, level and compact the ground at the designated scaffolding erection site, and then lay hard wooden mats on the construction ground.

[0047] S2, Erect the overall frame: First, fix the base on the pad, and install the clamping assembly on the base; then fix multiple adjusting rods on the base, and install and fix the scaffolding board to the adjusting rods with the second bolt; then insert multiple columns into the arc-shaped groove through the limiting hole, and then start the drive motor to rotate the screw to fix the columns.

[0048] S3, Install the second layer of connecting rods: Insert both ends of a connecting rod into the four-way connectors of the adjacent columns, and repeat the installation of connecting rods until each column is connected with multiple connecting rods;

[0049] S4. Repeat step S3 to erect the third layer of connecting rods, the fourth layer of connecting rods, and so on, until the overall height of the scaffolding meets the requirements of the construction operation.

[0052] S7, Erect safety components: Hang safety nylon netting flat under the scaffold boards; Lay toe boards with a height of not less than 0.2m on both sides of the scaffold boards and on the side away from the wall.

[0053] By adopting the above technical solutions, the efficient installation and erection of scaffolding was achieved.

[0054] In summary, this application includes at least one of the following beneficial technical effects:

[0055] 1. By setting up a base, clamping components, multiple columns, multiple four-way connectors, and multiple connecting rods, the efficient installation of scaffolding is achieved.

[0065] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0066] First aspect

[0067] Example 1:

[0068] Reference Figures 1 to 3 A construction site scaffold includes a base 1, a clamping assembly 2, multiple uprights 3, a four-way connector 4, a connecting rod 5, a diagonal brace 6, footboards 7, an adjusting rod 8, and a lifting ladder 9.

[0069] Reference Figure 1The base 1 is installed on the construction surface. The clamping assembly 2 is installed on the base 1 and fixedly connected to the base 1. The clamping assembly 2 has multiple pairs of arc-shaped grooves, which can approach and close to each other to form positioning holes, and multiple columns 3 are inserted into the positioning holes. The columns 3 are initially positioned by inserting them into the partially closed pairs of arc-shaped grooves, and then the arc-shaped grooves of the clamping assembly 2 are used to clamp and fix the columns 3 simultaneously, thereby achieving longitudinal fixed installation of the columns 3.

[0070] Reference Figure 1 and Figure 2 Multiple four-way connectors 4 are rotatably mounted on the uprights 3. Limiting elements 31, which are annular limiting plates, are provided at both the upper and lower ends of the four-way connectors 4 to prevent them from moving vertically. Elastic elements 41 are also provided inside the four-way connectors 4. The ends of multiple connecting rods 5 are inserted into the four-way connectors 4 and abut against the elastic elements 41. During installation, one end of the connecting rod 5 is engaged in the four-way connector 4 and abuts against the elastic elements 41, and the other end is engaged in another four-way connector 4 and abuts against the elastic elements 41. After assembling multiple connecting rods 5, the horizontal installation and fixation of multiple uprights 3 is completed. When installing and fixing the uprights 3, the clamping assembly 2 can achieve initial positioning of the uprights 3 through the unclosed arc-shaped grooves. Then, by bringing the arc-shaped grooves closer together to close, the uprights 3 can be installed and fixed. Combining the positioning and installation of the uprights 3 into one process greatly shortens the installation time and costs, thus achieving efficient scaffolding installation.

[0071] Reference Figure 2 and Figure 3 The elastic element 41 includes a spring 411 and a stop plate 412. The spring 411 is fixedly connected to the four-way connector 4, and the stop plate 412 is installed inside the four-way connector 4 and fixedly connected to it. The spring 411 provides a certain elastic buffering effect, absorbing some external force and vibration during construction, effectively reducing the impact and damage to the column 3 and connecting rod 5 under external force. Simultaneously, the spring 411 maintains a certain tension to ensure a stable connection. The stop plate 412, as a medium connecting the spring 411 and the four-way connector 4, serves to fix the spring 411 and prevent it from falling off. Furthermore, the use of the elastic element 41 makes the installation and fixing of the column 3 and connecting rod 5 more convenient and faster, eliminating cumbersome adjustment and fixing steps, and reducing installation time and labor costs.

[0072] Reference Figure 1The clamping assembly 2 includes multiple first clamping plates 21, a lead screw 22, and multiple second clamping plates 23. A bearing 11 is fixedly connected to the base 1, and one end of the lead screw 22 is rotatably connected to the bearing 11. The lead screw 22 includes a threaded section 221 and a smooth section 222, which are spaced apart on the lead screw 22. Multiple arc-shaped grooves are formed on the first clamping plates 21 and the second clamping plates 23, and the smooth section 222 rotatably passes through the first clamping plate 21. A limit ring 223 is also provided on the smooth section 222 (in conjunction with...). Figure 3 The limiting ring 223 abuts against the first clamping plate 21.

[0073] Reference Figure 1 The lead screw 22 passes through the second clamping plate 23, and the threaded section 221 is threadedly connected to the second clamping plate 23. Rotating the lead screw 22 can move the second clamping plate 23 closer to or away from the first clamping plate 21. Multiple arc-shaped grooves are provided on the first clamping plate 21 and the second clamping plate 23, allowing the column 3 to be placed into the partially closed arc-shaped grooves, providing initial longitudinal positioning for the column 3. The lead screw 22 has a structure of threaded section 221 and smooth section 222. When the lead screw 22 rotates, it moves the second clamping plate 23 on the threaded section 221 closer to the first clamping plate 21. However, because the limiting ring 223 abuts against the first clamping plate 21, the first clamping plate 21 is not moved by the second clamping plate 23. The lead screw 22 clamps the first clamping plate 21 located between the limiting ring 223 and the second clamping plate 23, thereby clamping the column 3 and achieving simultaneous longitudinal fixing of multiple columns 3, improving the installation efficiency of the scaffolding.

[0074] Reference Figure 3 and Figure 4 Multiple diagonal braces 6 are detachably connected to adjacent uprights 3, providing additional support and stability to the scaffolding. They transfer vertical loads to the ground and reduce bending and stress on the connecting rods 5 and uprights 3, thus mitigating the risk of lateral tilting of the scaffolding structure. Furthermore, the diagonal braces 6 also provide lateral support to the scaffolding structure. When facing crosswinds or other external forces, the diagonal braces 6 increase the scaffolding's resistance, prevent structural collapse, and improve its load-bearing capacity and overall structural stability.

[0075] Reference Figure 3 and Figure 4The diagonal brace 6 includes a diagonal rod 61, a first bolt 62, and a hook 63. Threaded holes are axially formed at both ends of the diagonal rod 61, and the thread of the first bolt 62 engages with these threaded holes. Multiple fixing ears 42 are provided on the four-way connector 4, positioned between adjacent four-way connectors 4. The end of the hook 63 is rotatably mounted on the head of the first bolt 62, engaging with the fixing ears 42. The length of the diagonal brace 6 is adjusted by installing the hook 63 onto the fixing ears 42 of adjacent four-way connectors 4 and then rotating the first bolt 62. Depending on the actual needs, when the hook 63 is placed on the adjacent fixing ear 42, rotating the first bolt 62 loosens the connection between the first bolt 62 and the diagonal rod 61, stretching the diagonal brace 6 to an appropriate length for easy installation. When it is necessary to tighten the connection between the diagonal brace 6 and the fixing ears 42, rotating the first bolt 62 in the opposite direction retracts the diagonal brace 6 to an appropriate length, thus achieving the effect of easy installation of the diagonal brace 6. Since the end of the hook 63 is rotatably mounted on the head of the first bolt 62, the hook 63 will not rotate when the first bolt 62 is rotated because it is locked on the fixing ear 42.

[0076] The scaffold board 7 is installed at the end of the column 3 away from the base 1. The scaffold board 7 is used to support the feet and provide a working platform for the operator, enabling the operator to stand or move on the scaffold to perform operations, thereby improving work efficiency and personnel safety.

[0077] Multiple adjusting rods 8 are mounted on the base 1, and the adjusting rods 8 are arranged parallel to the column 3. Furthermore, the adjusting rods 8 have grooves 81 along their height direction, and the scaffold board 7 is slidably connected to the adjusting rods 8. The scaffold board 7 has threaded blind holes that communicate with the grooves 81, and multiple limiting holes 71 are also provided on the scaffold board 7, with the column 3 slidingly engaging with the limiting holes 71. A second bolt 82 is also included, which passes through the grooves 81 and is threadedly connected to the threaded blind holes. The second bolt 82 is used to fix the adjusting rods 8 and the scaffold board 7. The scaffold board 7 not only provides a working platform for the operator but also limits the movement of the column 3. The slidable connection between the scaffold board 7 and the adjusting rods 8 on the base 1 allows for flexible adjustment of the height of the scaffold board 7 relative to the base 1, and then the adjusting rods 8 and the scaffold board 7 are fixed by the second bolt 82. In addition, limit holes 71 are provided on the scaffold board 7. When fixing the uprights 3, the bottom uprights 3 can be clamped and fixed by the clamping components 2. However, the part of the uprights 3 away from the base 1 may tilt due to gravity or wind. The limit holes 71 can prevent the uprights 3 from tilting, thereby avoiding vertical deviation and affecting the installation quality.

[0078] One end of the lifting ladder 9 is mounted on the base 1, and the other end is mounted on the scaffold board 7. Scaffolding is used for high-altitude operations, and the lifting ladder 9 can conveniently and quickly transport workers from the ground or lower levels to the working platform of the scaffolding, reducing the time and labor intensity of climbing up and down, and improving work efficiency.

[0079] The drive motor 224 is detachably connected to the lead screw 22, and the drive motor 224 is used to drive the lead screw 22 to rotate. Traditional manual rotation of the lead screw 22 requires considerable force and time, wasting labor and time. Furthermore, using the lead screw 22 to fasten the clamping plate to fix the column 3 requires ensuring the clamping strength. Using the drive motor 224 can output a larger torque to ensure installation strength, while also improving the efficiency of installing and fixing the column 3.

[0080] The implementation principle of Embodiment 1 of this application is as follows:

[0081] Reference Figure 3 First, the clamping assembly 2 allows for rapid initial positioning of the uprights 3, and the closed arc-shaped groove enables their installation and fixation, significantly shortening installation time. The structure of the clamping assembly 2 and connecting rod 5 ensures that the uprights 3 are firmly clamped and fixed in both the longitudinal and lateral directions, improving the overall stability of the scaffolding. The installation of the diagonal brace 6 provides additional support and stability to the scaffolding, reducing the risk of structural tilting and ensuring construction safety. The adjusting rod 8 and the footboard 7 ensure that the uprights 3 do not tilt during installation, and allow workers to flexibly adjust the height of the footboard 7 relative to the top layer of the scaffolding to adapt to different construction needs. The elastic element 41 provides a certain elastic buffering effect for the connecting rod 5, absorbing external forces and vibrations, protecting the uprights 3 and connecting rod 5 from impact and damage, while also facilitating the installation of the connecting rod 5. The lifting ladder 9 allows workers to move quickly and conveniently to the work platform, improving work efficiency. The use of the drive motor 224 greatly improves the installation efficiency of the uprights 3 while ensuring their fixing strength.

After adjustment, install and fix the scaffold board 7 to the adjusting rods 8 using the second bolt 82; then insert multiple uprights 3 into the arc-shaped grooves through the limiting holes 71 of the scaffold board 7, start the drive motor 224, rotate the lead screw 22 and fix the uprights 3; finally, use a laser instrument to observe the tilt of the uprights 3 to ensure that the uprights 3 do not tilt relative to the base 1 before proceeding with subsequent operations;

[0086] S3, Install the second layer of connecting rods 5: Rotate the four-way connector 4 located on the column 3 so that the openings of the two four-way connectors 4 face each other. Then, insert both ends of a connecting rod 5 into the four-way connectors 4 of the adjacent column 3 respectively, and repeat the installation of connecting rods 5 until each column 3 is connected with three or four connecting rods 5. The column 3 located at the edge of the scaffolding has three connecting rods 5 installed in one layer, and the column 3 located in the middle has four connecting rods 5 installed in one layer.
