Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically an adjustable support beam for a fixed disc buckle frame. Background Technology

[0002] The disc-lock support frame is a new type of direct-insertion steel pipe scaffolding with self-locking mechanism. It is composed of components such as uprights, double channel steel, supporting beam bases, horizontal bars, and diagonal braces. Compared with traditional coupler-type cantilevered external scaffolding, the external wall insert-type disc-lock steel pipe scaffolding has significant improvements in erection and dismantling efficiency, reliability, safety, cost savings, and energy conservation and environmental protection.

[0003] When setting up the support platform, the steel pipe extending from the bottom of the support beam base needs to be inserted between the two channel steels. Then, on the steel pipe on the support beam base, the disc-lock scaffold base is placed, and then the support platform is set up on the base.

[0004] Because the steel pipe on the support beam base is inserted between two channel steels, when the load-bearing platform built on the support beam base is under stress, the support beam base will slide and shift on the channel steel, which can easily cause safety accidents.

[0005] Currently, in order to prevent the support beam base from shifting on the channel steel, workers will use bolts to fix the support beam base to the channel steel, thereby fixing the support beam base and preventing it from shifting.

[0006] However, after fixing the support beam base to the channel steel with bolts, the staff cannot easily adjust the position of the support beam base. They can only adjust the support beam base after removing all the bolts, and the operation process is cumbersome and complicated. Summary of the Invention

[0008] It includes two uprights; a disc is fixedly connected to each of the two uprights; a double channel steel is provided on both discs; the double channel steel includes a pair of channel steels arranged back to back, and the two channel steels are fixed together by pipe bolts, and the uprights are located between the two channel steels;

[0009] Two support beam bases are provided between the two channel steels; the two support beam bases include steel pipes and support plates; the support plates are fixed to the steel pipes, and the steel pipe portion is located below the support plates; the outer surface of the side of the steel pipe located below the support plates is threaded.

[0012] Rectangular blocks are fixedly connected to the opposite end faces of the two concave plates located on both sides of the steel pipe, and the rectangular blocks are initially in contact with each other; a second half-groove is opened in the inner wall of each of the two rectangular blocks, and the two second half-groos are combined to form a whole circular groove; threads are opened in both of the two second half-groos.

[0013] Both rectangular blocks are mounted on a concave plate below them, and the drive blocks are initially in contact with each other; a third half-groove is formed in the inner wall of the two drive blocks, and the two third half-groos are combined to form a complete circular groove; threads are formed in both third half-groos, and the threaded rods pass through the circular groove formed by the third half-groos and mesh with the threads in the third half-groos.

[0014] Both of the two threaded rods have evenly arranged gear teeth fixedly connected to their opposite sides at the ends of the threaded rods; one of the channel steels has two notches, and the notches correspond to the gear teeth.

[0015] Gears are rotatably connected to both slots, and the gears mesh with each other; a drive rod is fixedly connected to the middle of both gears, and the drive rod extends through the channel steel to the outside of the channel steel.

[0016] Preferably, each of the driving blocks has a groove on the surface of the concave plate on the side that is in contact with the concave plate;

[0017] Each of the drive blocks has a slider fixedly connected to its surface on the side facing the slide groove, and the slider slides within the slide groove.

[0018] Each slider has a spring fixedly connected to its bottom end face, and the other side of each spring is connected to a groove.

[0019] Preferably, each of the concave plates is provided with a stabilizing plate at its bottom; the stabilizing plates located below the concave plates on both sides of the steel pipe are connected by connecting rods;

[0020] Each of the concave plates has a slide rail on the side near the stabilizing plate, and the stabilizing plate slides within the slide rail.

[0021] The connecting rod is a helical rod, with the middle of the helical rod as the dividing line, and the threads on both sides of the dividing line are opposite; the connecting rod is threadedly engaged with the stabilizing plate.

[0022] Preferably, the pallet has evenly arranged first threaded holes;

[0027] The beneficial effects of this invention are as follows:

[0028] 1. The adjustable support beam of the fixed disc buckle frame of the present invention can limit the position of the support beam base itself by turning the steel pipe at the bottom of the support beam base into the second half groove with threads through the thread, so as to prevent the steel pipe at the bottom of the support beam base from shifting between the two channel steels. By pressing the steel pipe at the bottom of the support beam base against the upper surface of the drive block, and due to the friction between the steel pipe and the drive block, the steel pipe can be limited, thereby improving the stability of the support beam base. When the support plate is located on the top of the two concave plates and is in contact with the top of the concave plates, the concave plates can support the support plate, thereby further improving the stability of the support beam base.

[0029] 2. The adjustable support beam of the fixed disc buckle frame of the present invention, by rotating the threaded rod, causes the threaded rod to move the concave plate on the channel steel. At the same time, the concave plate will move the support beam base as a whole, so that the support beam base does not need to be removed from the second half groove on the rectangular block of the concave plate. The position of the support beam base can be adjusted while fixing the support beam base. Compared with the existing fixing method of fixing the support beam base to the channel steel with bolts, the method of the present invention is simple and convenient to operate.

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] like Figures 1 to 10 As shown, this invention provides an adjustable support beam for a fixed disc buckle frame.

[0045] It includes two uprights 1; each of the two uprights 1 is fixedly connected to a disc 11; the two discs 11 are provided with a double channel steel 12; the double channel steel 12 includes a pair of channel steels arranged back to back, and the two channel steels are fixed together by a pipe bolt 13, and the uprights 1 are located between the two channel steels.

[0046] Two support beam bases 2 are provided between the two channel steels; the two support beam bases 2 include steel pipes 21 and support plates 22; the support plates 22 are fixedly connected to the steel pipes 21, and the steel pipes 21 are partially located below the support plates 22; the outer surface of the side of the steel pipes 21 located below the support plates 22 is threaded.

[0047] It also includes an adjustment mechanism; the adjustment mechanism includes a fixing block 3; the two channel steels are fixedly connected to each other at the middle position of the channel steel on opposite sides, and the two fixing blocks 3 are in close contact with each other;

[0048] Each of the two fixing blocks 3 has a first half-groove 31, and the two first half-groove 31 are combined to form a whole circular groove; two threaded rods 32 are rotatably connected in the circular groove, and both threaded rods 32 extend to one side of the pipe plug 13; both sides of the two steel pipes 21 are slidably connected to concave plates 4 on the channel steel, and the support plate 22 on the column is located on the upper surface of the concave plate 4;

[0049] Rectangular blocks 41 are fixedly connected to the opposite end faces of the two concave plates 4 on both sides of the steel pipe 21, and the rectangular blocks 41 are initially in contact with each other; a second half-groove 42 is opened in the inner wall of each of the two rectangular blocks 41, and the two second half-groove 42 are combined to form a whole circular groove; threads are opened in both of the two second half-groove 42.

[0050] Below the two rectangular blocks 41, on the concave plate 4, a driving block 43 is installed, and the driving blocks 43 are initially in contact with each other; a third half-groove 44 is formed in the inner wall of the two driving blocks 43, and the two third half-groove 44 are combined to form a complete circular groove; threads are formed in the two third half-groove 44, and threaded rods 32 pass through the circular groove formed by the third half-groove 44 and mesh with the threads in the third half-groove 44;

[0051] Both of the two threaded rods 32 have uniformly arranged gear teeth 33 fixedly connected to their ends on opposite sides; one of the channel steels has two notches, and the notches correspond to the gear teeth 33.

[0052] Gears 34 are rotatably connected to both of the notches, and gears 34 mesh with gear teeth 33; drive rods 35 are fixedly connected to the middle of both gears 34, and drive rods 35 extend through the channel steel to the outside of the channel steel.

[0053] During installation, when installing the support beam base 2, the worker first inserts the steel pipe 21 on the support beam base 2 between the two opposing concave plates 4. Since the steel pipe 21 located below the support plate 22 has threads, and since the second half-groove 42 inside the rectangular block 41 also has threads, the worker rotates the steel pipe 21 on the support beam base 2, causing the steel pipe 21 located below the support plate 22 to gradually rotate into the circular groove formed by the combination of the two second half-grooves 42, and the threads on the steel pipe 21 gradually mesh with the threads in the second half-groove 42. When the bottom of the steel pipe 21 rotates to below the rectangular block 41, the bottom of the steel pipe 21 will abut against the upper surface of the drive block 43. Due to the friction between the steel pipe 21 and the drive block 43, the steel pipe 21 can be limited, thereby improving the stability of the support beam base 2. When the support plate 22 is located on top of the two concave plates 4 and is in contact with the top of the concave plates 4, the concave plates 4 can support the support plate 22, thereby further improving the stability of the support beam base 2. At this time, the support beam base 2 is installed and the load-bearing platform can be built.

[0054] When the position of the support beam base 2 needs to be adjusted, the operator uses a wrench to rotate the drive rod 35 in the forward or reverse direction. When the drive rod 35 rotates, it will drive the gear 34 to rotate. Since the gear 34 meshes with the gear teeth 33 on the threaded rod 32, it can push the gear teeth 33 to rotate. The gear teeth 33 will drive the threaded rod 32 to rotate in the first half groove 31 of the fixed block 3. Since the threaded rod 32 meshes with the thread in the third half groove 44 on the drive block 43, the drive block 43 will be pushed to move between the two channel steels during the rotation of the threaded rod 32. During the movement of the drive block 43, the concave plate 4 will slide along the channel steel. At the same time, the concave plate 4 will drive the rectangular block 41, the steel pipe 21 in the second half groove 42 on the rectangular block 41, and the support plate 22 fixed on the steel pipe 21 to move. Thus, the position of the support beam base 2 on the channel steel can be adjusted. When the position of the support beam base 2 is adjusted to the appropriate position, the drive rod 35 can be stopped.

[0055] By threading the steel pipe 21 at the bottom of the support beam base 2 into the threaded second half groove 42, the support beam base 2 itself can be limited, preventing the steel pipe 21 at the bottom of the support beam base 2 from shifting between the two channel steels. By pressing the steel pipe 21 at the bottom of the support beam base 2 against the upper surface of the drive block 43, and due to the friction between the steel pipe 21 and the drive block 43, the steel pipe 21 can be limited, thereby improving the stability of the support beam base 2. When the support plate 22 is located on top of the two concave plates 4 and is in contact with the top of the concave plates 4, the concave plates 4 can support the support plate 22, thereby further improving the stability of the support beam base 2.

[0056] By rotating the threaded rod 32, the threaded rod 32 drives the concave plate 4 to move on the channel steel. At the same time, the concave plate 4 drives the support beam base 2 to move as a whole. Therefore, it is not necessary to remove the support beam base 2 from the second half groove 42 on the rectangular block 41 on the concave plate 4. The position of the support beam base 2 can be adjusted while fixing the support beam base 2. Compared with the existing fixing method of fixing the support beam base 2 to the channel steel with bolts, the method of the present invention is simple and convenient to operate.

[0057] In a specific embodiment, each of the driving blocks 43 has a groove 45 on the side of the concave plate 4 that is in contact with the concave plate 4.

[0058] Each of the drive blocks 43 has a slider 46 fixedly connected to the side of the drive block 43 facing the slide groove 45, and the slider 46 slides in the slide groove 45.

[0059] Each slider 46 has a spring fixedly connected to its bottom end face, and the other side of each spring is connected to the groove 45.

[0060] During operation, when the steel pipe 21 located below the support plate 22 abuts against the drive block 43, the drive block 43 is subjected to the pressure of the steel pipe 21 and will move slightly downward, thereby driving the slider 46 to move downward in the groove 45 and compressing the spring. During the downward movement of the drive block 43, the second half groove 42 will move downward. When the second half groove 42 moves downward, it will compress the threaded rod 32 in the second half groove 42, thereby increasing the friction between the second half groove 42 and the threaded rod 32, thereby increasing the difficulty of rotating the second threaded rod 32, improving the fixing effect on the drive block 43, and thus improving the fixing effect on the support beam base 2.

[0061] In a specific embodiment, each of the concave plates 4 is provided with a stabilizing plate 5 at its bottom; the stabilizing plates 5 located below the concave plates 4 on both sides of the steel pipe 21 are connected by connecting rods 51.

[0062] Each of the concave plates 4 has a slide rail 52 on the side near the stabilizing plate 5, and the stabilizing plate 5 slides within the slide rail 52.

[0063] The connecting rod 51 is a helical rod, and the threads on both sides of the helical rod are opposite with the middle as the dividing line; the connecting rod 51 is threadedly engaged with the stabilizing plate 5;

[0064] During operation, since each concave plate 4 has a stabilizing plate 5 at its bottom, and the corresponding stabilizing plates 5 are connected by a connecting rod 51, the presence of the connecting rod 51 can connect two opposite concave plates 4 together, thereby preventing the position of the two opposite concave plates 4 from deviating.

[0065] Since the connecting rod 51 is a helical rod, and the threads on both sides of the helical rod are opposite with the middle as the dividing line, after the support beam base 2 is installed, the operator can rotate the connecting rod 51. The connecting rod 51 will drive the stabilizing plate 5 to move closer to the channel steel position in the slide 52, and make the stabilizing plate 5 clamp on the two channel steels, thereby further improving the stability of the concave plate 4.

[0066] In a specific embodiment, the pallet 22 is provided with uniformly arranged first threaded holes 23;

[0067] Below each of the first threaded holes 23, a second threaded hole 24 is evenly arranged on the concave plate 4, and the first threaded hole 23 and the second threaded hole 24 correspond one-to-one; a fixing bolt 25 is engaged in the corresponding first threaded hole 23 and second threaded hole 24.

[0068] The bottom of the concave plate 4 is attached to the bottom of the channel steel, and a gap is left between the top of the channel steel and the top of the concave plate 4.

[0069] Below each of the second threaded holes 24, a roller 26 is rotatably connected within the concave plate 4; each of the rollers 26 has a through hole 27 corresponding to the second threaded hole 24.

[0070] The diameter of the through hole 27 is slightly larger than the maximum diameter of the second threaded hole 24, and the through hole 27 has a rounded corner design.

[0071] During operation, after the support beam base 2 is installed, the first threaded hole 23 on the support plate 22 corresponds one-to-one with the second threaded hole 24 on the concave plate 4. Then, the worker first turns the fixing bolt 25 into the first threaded hole 23, then into the second threaded hole 24, and then through the through hole 27 on the roller 26, and continues to turn the bolt. When the bottom of the bolt contacts the channel steel, the bolt continues to be turned. During the process of continuing to turn the bolt, the bottom of the concave plate 4 will be in contact with the bottom of the channel steel, leaving a gap between the top of the channel steel and the bottom of the concave plate 4. During this process, since the fixing bolt 25 is pressed against the channel steel, the concave plate 4 can be further fixed, and the concave plate 4 will be fixed to the channel steel if it shifts.

[0072] When the position of the support beam base 2 needs to be adjusted, the operator rotates the bolt in the opposite direction and rotates the bottom of the bolt into the first threaded hole 23. At this time, the bolt no longer supports the concave plate 4, and the concave plate 4 will move downward and make the roller 26 fit against the top of the channel steel. Then, the operator rotates the threaded rod 32. When the threaded rod 32 moves the concave plate 4, the roller 26 will rotate on the top of the channel steel, thereby reducing the friction between the concave plate 4 and the channel steel, making it easier for the concave plate 4 to move on the channel steel. After the support beam base 2 is adjusted, the fixing bolt 25 is pressed against the channel steel again.

[0073] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
