Description

Technical Field

[0001] The present invention belongs to the technical field of scaffolding, and more specifically, relates to an adjustable floor-standing scaffolding vertical pole and an adjustment method thereof. Background Art

[0002] In the construction field, sloped structural designs are generally encountered. In such cases, during the erection process of traditional floor-standing disc-socket scaffolding, problems such as uneven bottoms, inability to connect the bottom-sweeping bars, and inability to ensure the lower cushion blocks may occur, making the erection difficult. This often leads to a decrease in the overall stability of the scaffolding, low construction efficiency, and even potential safety accidents. The traditional scaffolding base support design often cannot adapt to such complex construction environments and cannot meet construction requirements. Therefore, the present invention proposes an adjustable floor-standing scaffolding vertical pole. By freely adjusting the height of the bottommost first-section vertical pole, when encountering a structural surface with a two-way slope, the height of the bottom-sweeping bar and the flatness of the framework can be ensured through adjustment, improving construction efficiency and safety.

[0003] In the prior art, Patent CN220247517U: An adjustable vertical pole for a disc-socket scaffolding can adjust the height of the scaffolding according to on-site construction requirements, improving stability and safety. However, the focus is on adjusting the middle vertical poles. When encountering uneven bottoms or sloped structures, the continuous presence of the bottom-sweeping bars cannot be ensured.

[0004] In the prior art, Patent CN107190960A: A scaffolding that is easy to adjust solves the problem of being able to fix it on uneven and sloped foundation surfaces. However, this method is cumbersome to install, fails to effectively utilize the mobility of the framework, has a narrow erection range, and is only applicable to operation scaffolds.

[0005] In the prior art, Patent CN103233575A: A telescopic vertical pole solves the problems of cumbersome scaffolding installation and inability to adjust the height significantly, and does not require the use of vertical poles of multiple specifications. However, the through holes arranged on the scaffolding easily affect the strength of the scaffolding itself and reduce its bearing capacity. Summary of the Invention

[0006] Aiming at the above defects or improvement requirements of the prior art, the present invention provides an adjustable floor-standing scaffolding vertical pole and an adjustment method thereof. First, by adjusting the angle between the adjusting base and the connecting plate, the adjusting base is made to closely adhere to the ground while the connecting plate remains horizontal, so that the vertical pole remains vertical. Then, by adjusting the length of the inner strut inside the outer strut, the tops of all the outer struts are made to be at the same height, and the bottom-sweeping bars are all connected to the tops of the outer struts, so that the bottom-sweeping bars connecting the vertical poles are all in the same horizontal plane, thereby realizing the adjustment of the scaffolding vertical pole, strengthening the structural strength of the scaffolding splicing, providing a flat construction platform, facilitating the construction of workers, and ensuring construction safety.

[0023] The second adjusting points are evenly arranged around the second rotating head to form an adjusting point array. The protruding structure of the second adjusting points has a spherical convex surface.

[0024] Furthermore, the number of the first adjusting holes and the positional relationship between the first adjusting holes and the first rotating hole are the same as the number of the first adjusting points and the positional relationship between the first adjusting points and the first rotating head. The number of the second adjusting holes and the positional relationship between the second adjusting holes and the second rotating hole are the same as the number of the second adjusting points and the positional relationship between the second adjusting points and the second rotating head;

[0034] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0035] 1. The adjustable ground-type scaffolding upright pole of the present invention first adjusts the angle between the base and the connecting plate so that the adjustable base is close to the ground, and the connecting plate is kept horizontal so that the upright pole is kept in a vertical state, and then the length of the inner support rod inside the outer support rod is adjusted so that the tops of all the outer support rods are at the same height, and the sweeping rods are connected at the top ends of the outer support rods so that the sweeping rods connected to the upright poles are in the same horizontal plane, so as to realize the adjustment of the scaffolding upright poles, strengthen the structural strength of the scaffolding splicing, and provide a flat construction platform, which is convenient for workers to construct and ensures the safety of construction.

[0036] 2. The adjustable ground-type scaffolding upright pole of the present invention can rotate between the adjusting rod, the base and the connecting plate when the upright pole is not under pressure. After the upright pole is under pressure, the limiting effect between the adjusting point array and the adjusting hole array makes the adjusting rod unable to rotate, thereby achieving a stable connection.

[0037] 3. The adjustable ground-type scaffolding upright pole of the present invention can be connected by simply putting the outer support rod on the inner support rod when connecting the inner support rod and the outer support rod. When the height of the upright pole needs to be changed, it is only necessary to rotate the outer support rod so that the support block corresponds to the adjustment groove of different depths, thereby changing the length of the inner support rod in the outer support rod, thereby adjusting the length of the upright pole.

[0052] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the drawings and embodiments.

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] In the setting of a conventional scaffolding, generally, vertical poles are set on the ground, and then a bottom bar at a relatively low height from the ground is set on the vertical poles. Taking the height of the bottom bar as a reference, vertical bars and horizontal bars are gradually connected upward. Normally, to ensure the convenience of transportation and installation, the lengths of the vertical bars and horizontal bars are constant. Therefore, when installing the scaffolding, it is necessary to ensure that all the bottom bars are in the same horizontal plane to ensure that the connection heads of the upper vertical bars are in the same horizontal plane, and further ensure that the upper horizontal bars are installed horizontally. In this way, the structural strength of the scaffolding splicing is strengthened, and a flat construction platform is provided to facilitate the construction of workers and ensure the safety of construction. However, generally, the length of the vertical pole is also a standard length. When encountering uneven or inclined ground, it is very difficult to adjust the vertical pole and it is difficult to ensure the horizontal installation of the bottom bar.

[0054] Embodiment 1

[0055] An embodiment of the present invention provides an adjustable floor-standing scaffolding vertical pole, including: a longitudinal adjustment unit 3 provided at the bottom end of the bottommost vertical bar 1 and an angle adjustment unit 4 provided at the bottom end of the longitudinal adjustment unit 3. Among them, the longitudinal adjustment unit 3 includes an inner support rod 31 and an outer support rod 32. The inner support rod 31 is provided inside the outer support rod 32, and the overall length of the vertical pole is changed by adjusting the overlapping length between the two; the angle adjustment unit 4 is provided between the ground and the longitudinal adjustment unit 3, including a base 41 and a connecting plate 42. By adjusting the angle between the base 41 and the connecting plate 42, the angle of the vertical pole is changed to ensure that the vertical pole is always in a vertical state. When in use, first adjust the angle between the base 41 and the connecting plate 42 to make the adjusting base 41 closely adhere to the ground, while the connecting plate 42 remains horizontal, so that the vertical pole remains in a vertical state. Then, adjust the length of the inner support rod 31 inside the outer support rod 32 so that the tops of all the outer support rods 32 are at the same height, and the bottom bars are all connected to the tops of the outer support rods 32, so that the bottom bars connecting the vertical poles are all in the same horizontal plane, so as to realize the adjustment of the scaffolding vertical pole, strengthen the structural strength of the scaffolding splicing, and provide a flat construction platform to facilitate the construction of workers and ensure the safety of construction.

[0056] Among them, the base 41 and the connecting plate 42 are connected by adjusting rods 43. There are at least three adjusting rods 43. One end is rotatably connected to the base 41, and the other end is rotatably connected to the connecting plate 42. A plurality of inclined surfaces are provided on the top surface of the base 41. The plurality of inclined surfaces intersect at the center position of the base 41, and the intersection point is concave inward. Each of the inclined surfaces is provided with a first rotating hole 411. Centered on the first rotating hole 411, at least one circle of first adjusting holes 412 is provided around its circumference. The first rotating hole 411 is a stepped round hole with a larger inner diameter and a smaller outer diameter, that is, the first rotating hole 411 is divided into an inner layer and an outer layer. The outer layer is provided on the surface of the inclined plate of the base 41 and is connected to the inner layer. The inner side is provided inside the inclined plate of the base 41, and its diameter is larger than that of the outer layer. The first adjusting holes 412 are evenly arranged around the first rotating hole 411 to form an adjusting hole array. The first adjusting holes 412 are concave holes, and the concave surface is a spherical surface. The spherical surface is a hemispherical surface or less than a hemispherical surface. A plurality of second rotating holes 421 are provided around the center of the bottom surface of the connecting plate 42. Centered on the second rotating hole 421, at least one circle of second adjusting holes 422 is provided around its circumference. The second rotating hole 421 is a stepped round hole with a larger inner diameter and a smaller outer diameter, that is, the second rotating hole 421 is divided into an inner layer and an outer layer. The outer layer is provided on the surface of the connecting plate 42 and is connected to the inner layer. The inner side is provided inside the connecting plate 42, and its diameter is larger than that of the outer layer. The second adjusting holes 422 are evenly arranged around the second rotating hole 421 to form an adjusting hole array. The second adjusting holes 422 are concave holes, and the concave surface is a spherical surface. The spherical surface is a hemispherical surface or less than a hemispherical surface.

[0057] The bottom end of the adjusting rod 43 is rotatably connected to the base 41, and the top end is rotatably connected to the connecting plate 42. At the center position of the bottom end of the adjusting rod 43, there is a first rotating head 431, and at least one circle of first adjusting points 432 is arranged circumferentially around the first rotating head 431. The first rotating head 431 is connected to the lower end face of the adjusting rod 43 through a short rod, and its head is a disc. The first rotating head 431 is arranged in the inner layer of the first rotating hole 411. The bottom end of the adjusting rod 43 is connected to the base 41 through the first rotating head 431 and the first rotating hole 411, and the adjusting rod 43 can rotate around the first rotating hole 411. The first adjusting points 432 are evenly arranged around the first rotating head 431 to form an adjusting point array. The raised structure of the first adjusting points 432 has a spherical surface as its convex surface, and the spherical surface is a hemispherical surface or less than a hemispherical surface. At the center position of the top end of the adjusting rod 43, there is a second rotating head 433, and at least one circle of second adjusting points 434 is arranged circumferentially around the second rotating head 433. The second rotating head 433 is connected to the top end face of the adjusting rod 43 through a short rod, and its head is a disc. The second rotating head 433 is arranged in the inner layer of the second rotating hole 421. The top end of the adjusting rod 43 is connected to the connecting plate 42 through the second rotating head 433 and the second rotating hole 421, and the adjusting rod 43 can rotate around the second rotating hole 421. The second adjusting points 434 are evenly arranged around the second rotating head 433 to form an adjusting point array. The raised structure of the second adjusting points 434 has a spherical surface as its convex surface, and the spherical surface is a hemispherical surface or less than a hemispherical surface.

[0058] The spherical surface height and radius of the first adjusting hole 412 are the same as those of the first adjusting point 432; the spherical surface height and radius of the second adjusting hole 422 are also the same as those of the second adjusting point 434. The number of the first adjusting holes 412 and their positional relationship with the first rotating hole 411 are the same as the number of the first adjusting points 432 and their positional relationship with the first rotating head 431. The number of the second adjusting holes 422 and their positional relationship with the second rotating hole 421 are the same as the number of the second adjusting points 434 and their positional relationship with the second rotating head 433. So that all the first adjusting points 432 are placed in the first adjusting holes 412, and all the second adjusting points 434 are placed in the second adjusting holes 422.

[0059] After being limited by the first rotating head 431 between the bottom end face of the adjusting rod 43 and the inclined plane of the base 41, there is still a gap, so that the adjusting rod 43 can rotate with the base 41 without being affected by the first adjusting hole 412 and the first adjusting points 432; after being limited by the second rotating head 433 between the top end face of the adjusting rod 43 and the connecting plate 42, there is still a gap, so that the adjusting rod 43 can rotate with the connecting plate 42 without being affected by the second adjusting hole 422 and the second adjusting points 434.

[0060] It can be understood that when the vertical pole is not under pressure, since the adjusting rod 43 can rotate between the base 41 and the connecting plate 42, and after being under pressure, due to the limiting effect between the adjusting point array and the adjusting hole array, the adjusting rod 43 cannot rotate, thus achieving a stable connection.

[0061] As a further preference, the bottom end of the adjusting rod 43 is also beveled, the angles between each bevel are different, and the lengths of multiple adjusting rods 43 are different, and their connection states are not centrosymmetric with each other.

[0062] As a further preference, to enable the adjusting rod 43 to have a better angle adjustment effect, multiple outward bevels can also be provided on the bottom surface of the connecting plate 42, and corresponding structures are also provided at the top end of the adjusting rod 43.

[0063] It can be understood that by rotating the adjusting rod 43, the connecting plate 42 and the base 41 can be parallel or inclined within a certain angle range to adapt to uneven or concave-convex terrain.

[0064] The bottom end of the inner support rod 31 is connected to the top surface of the connecting plate 42, and support blocks 34 are provided on its surface. The support blocks 34 are used in pairs and are symmetrically arranged on the surface of the inner support rod 31, and the cross-section of the support block 34 is square. The inside of the outer support rod 32 is a cylindrical cavity, the diameter of the cylindrical cavity is the same as the diameter of the inner support rod 31, and multiple adjusting grooves 33 are provided on its inner wall. The adjusting grooves 33 are symmetrically arranged in multiple pairs along the central axis of the outer support rod 32, and each pair of adjusting grooves 33 is the same. The cross-section of the adjusting groove 33 is the same as the cross-section of the support block 34, and its depth is distributed in a stepped manner.

[0065] It can be understood that when connecting the inner support rod 31 and the outer support rod 32, the connection can be completed only by sleeving the outer support rod 32 on the inner support rod 31. When it is necessary to change the height of the vertical pole, only by rotating the outer support rod 32 to make the support block 34 correspond to adjusting grooves 33 with different depths, the length of the inner support rod 31 inside the outer support rod 32 can be changed, thereby adjusting the length of the vertical pole.

[0066] After the vertical pole is installed, use the ground-sweeping rod to connect the vertical poles accordingly, and gradually connect the vertical rods 1 and the crossbars 2 to the vertical poles. The vertical rods 1 and the crossbars 2 are detachably and fixedly connected through the connecting plate 5.
