Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a double-channel steel support beam level adjustment device. Background Technology

[0002] With rapid societal development, various types of buildings are springing up like mushrooms after rain. Buildings are becoming increasingly larger, with more and more high-rise buildings. To withstand the enormous loads of these structures, the number of load-bearing beams, floor slabs, and shear walls is also increasing. To improve construction efficiency and save costs, the bottom of the beams now uses double-channel steel with top supports instead of the traditional uprights and top supports. However, due to the numerous uprights used in the formwork erection process, misalignment of the support plates on the uprights frequently occurs, causing the double-channel steel beams to tilt. Figure 1 As shown, this results in uneven stress distribution and poor stability of the formwork support frame (rectangular tube 5) at the bottom of the main beam, posing a risk of beam formwork bulging, bursting, or even frame collapse.

[0003] Prior art: A device and method for adjusting the main beam inside a disc-lock scaffold (CN202411267863.5). The device in this application includes a sliding rod and an adjusting mechanism. A sliding disc is slidably mounted on the sliding rod, and the sliding disc is detachably connected to the end of the support beam that supports the concrete beam formwork. Horizontal connecting rods are fixedly mounted in the same direction at both ends of the sliding rod, and the horizontal connecting rods can be detachably connected to adjacent discs on the uprights. The adjusting mechanism is used to adjust the fixed position of the sliding disc on the sliding rod. The method in this application fixes the device to the discs on the uprights, fixes the support beam to the sliding disc, and adjusts the height of the sliding disc so that the height of the support beam matches the bottom of the concrete beam formwork to be supported. This device has the problems of relatively complex structure and many operation steps.

[0004] Therefore, for the horizontal placement of the double-channel steel support beam at the bottom of the main beam, it is necessary to adopt a more efficient device that can adjust the level of the double-channel steel support beam. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems of the prior art by disclosing a double-channel steel support beam level adjustment device. The structural design of this device solves the problem that the double-channel steel support beam cannot be placed horizontally on the support plate due to the misalignment of the upright discs on both sides of the beam bottom caused by the failure to properly arrange the support rods of the formwork frame. This results in the double-channel steel support beam being in an inclined state with uneven force and poor stability of the beam bottom formwork frame. Ultimately, this device ensures the safety and stability of the beam bottom formwork frame and avoids quality problems such as bulging and bursting of the beam formwork.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A double-channel steel support beam leveling device, comprising: a formwork support frame, a first support plate, a movable support structure, a double-channel steel support beam, and a top support.

[0008] The formwork support frame is fixed on the foundation support structure. The formwork support frame includes two vertically arranged uprights, one of which is provided with a first support plate, and the other upright is provided with a movable support structure.

[0009] One end of the double-channel steel support beam is erected on the first support plate, and the other end is erected on the movable support structure, wherein the movable support structure is set at the same height as the first support plate.

[0010] The top support is fixed on the double-channel steel support beam and completes the support structure for the top side of the beam to be poured.

[0011] According to a preferred embodiment, the movable support structure includes: a disc clip and a double fastener structure.

[0012] The disc clamp is attached to the upright of the formwork support frame to provide a supporting plane for the double channel steel support beam;

[0013] The double fastener structure has a disc-shaped bottom side that hugs the upright of the formwork support frame and contacts the bottom side of the disc-shaped fastener, providing vertical support for the disc-shaped fastener.

[0014] According to a preferred embodiment, the disc clip includes: a first semi-disc and a second semi-disc, wherein one end of the first semi-disc is hinged to the second semi-disc via a disc clip pin.

[0015] The other end of the first semi-disc is connected to the second semi-disc via a first bolt, thereby achieving the closing and fixing of the first and second semi-discs.

[0016] Furthermore, when the first and second semi-circular disks are closed, a first cavity is formed at the center of the two semi-circular disks to accommodate the passage of the uprights of the formwork support frame.

[0017] According to a preferred embodiment, the end of the first bolt is provided with a double nut structure to define the relative position of the two semi-discs.

[0018] According to a preferred embodiment, the double fastener structure includes a first fastener and a second fastener, the two fasteners being vertically overlapped and connected to each other via a connecting pin.

[0019] According to a preferred embodiment, the first fastener and the second fastener are the same clamp-type structure.

[0020] According to a preferred embodiment, the first fastener includes: a first arc plate and a second arc plate. One end of the first arc plate is hinged to the end of the second arc plate via a fastener pin, and the other end of the first arc plate is movably connected to the other end of the second arc plate via a second bolt, thereby realizing the closing and fixing of the first arc plate and the second arc plate. When the first arc plate and the second arc plate are closed and fixed, the upright of the formwork support frame is clamped in the second cavity between the first arc plate and the second arc plate.

[0021] According to a preferred embodiment, the second arc-shaped disk body is provided with a vertical connecting hole for accommodating a connecting pin.

[0022] According to a preferred embodiment, the contact surfaces of the first and second arcuate disks with the upright are provided with toothed protrusions.

[0023] According to a preferred embodiment, the top support includes: a top rod, a top block, and an adjusting plate;

[0024] The top block is located at the top of the top rod, and the adjustment disc is sleeved on the top rod and connected to the top rod by a threaded structure.

[0025] When supporting the formwork support structure of the beam to be poured, the top block completes the horizontal support of each rectangular tube in the beam formwork support structure. The top rod passes through the double channel steel support beam, and the adjustment plate is set on the surface of the double channel steel support beam. The height of the top block can be adjusted by rotating the adjustment plate.

[0026] The aforementioned main solution of this utility model and its various further alternative solutions can be freely combined to form multiple solutions, all of which are solutions that can be adopted by this utility model and for which protection is sought. Those skilled in the art, after understanding the solution of this utility model, will realize, based on existing technology and common knowledge, that there are many combinations, all of which are technical solutions to be protected by this utility model; therefore, they are not exhaustively listed here.

[0027] The beneficial effects of this utility model are:

[0028] In this device, the disc clamps are reinforced and fixed using bolts and nuts, which facilitates installation and disassembly by workers and ensures that the solid disc clamps are firmly locked onto the uprights. Both the upper and lower surfaces of the solid disc clamps and the double fasteners are flat, allowing the double-channel steel support beams to rest stably on the upper surface of the disc clamps. Simultaneously, the lower surface of the disc clamps and the upper surface of the double fasteners make smooth contact, improving the disc clamps' anti-slip force and ensuring better load-bearing capacity for the double-channel steel support beams, thus maintaining the overall stability of the supporting rectangular tubes. This device effectively solves the problem of the double-channel steel support beams being unable to be placed horizontally due to operator error causing the support plates on both sides of the uprights at the bottom of the main beam to be at different elevations. Furthermore, it is easy to install and disassemble and can be reused multiple times. Attached Figure Description

[0045] The formwork support frame 10 is fixed to the foundation support structure. The formwork support frame includes two vertically arranged uprights, one of which is equipped with a first support plate 11, and the other upright is equipped with a movable support structure 12. One end of the double channel steel support beam 13 is erected on the first support plate 11, and the other end is erected on the movable support structure 12, with the movable support structure 12 and the first support plate 11 being set at the same height. The top support 14 is fixed on the double channel steel support beam 13 and completes the support structure for the top side of the beam to be poured.

[0046] In this application, the movable support structure 12 is designed to ensure that its vertical position can be adjusted on the uprights, thereby keeping the movable support structure 12 at the same height or horizontal line as the first support plate 11. This ensures that the double-channel steel support beam 13 remains horizontal, avoiding the problem of uneven stress on the formwork support structure and poor stability of the beam bottom formwork support structure caused by the double-channel steel support beam 13 being in an inclined state. Ultimately, this ensures the safety and stability of the beam bottom formwork support structure and avoids quality problems such as bulging and bursting of the beam formwork.

[0047] Preferably, the movable support structure 12 includes: a disc clip 16 and a double fastener structure. The disc clip 16 is attached to the upright of the formwork support frame 10 to provide a support plane for the double channel steel support beam 13.

When the first semi-disc 101 and the second semi-disc 102 are closed, a first cavity 106 is formed at the center of the two semi-discs to accommodate the passage of the upright of the formwork support frame 10.

[0049] Furthermore, the end of the first bolt 104 is provided with a double nut structure 105, which is used to fix the relative position of the two semi-discs.

[0050] Preferably, the double-fastener structure includes a first fastener 17 and a second fastener 18, which are vertically overlapping and connected to each other via a connecting pin 19. Further, the first fastener 17 and the second fastener 18 are identical clamp-type structures. This double-fastener structure ensures sufficient vertical support for the disc clip 16.

[0051] Preferably, the first fastener 17 includes a first arc plate 201 and a second arc plate 202. One end of the first arc plate 201 is hinged to the end of the second arc plate 202 via a fastener pin 203, and the other end of the first arc plate 201 is movably connected to the other end of the second arc plate 202 via a second bolt 205, thereby realizing the closing and fixing of the first arc plate 201 and the second arc plate 202. When the first arc plate 201 and the second arc plate 202 are closed and fixed, the upright of the formwork support frame 10 is clamped in the second cavity 204 between the first arc plate 201 and the second arc plate 202.

[0052] Preferably, the second arc disk 202 has a vertical connecting hole 206 on its disk body for accommodating the connecting pin 19.

[0053] Preferably, the contact surfaces of the first arc-shaped disk 201 and the second arc-shaped disk 202 with the upright are provided with toothed protrusions. The toothed protrusions increase the friction between the first arc-shaped disk 201 and the second arc-shaped disk 202 and the upright.

[0054] Preferably, the top support 14 includes: a top rod 301, a top block 302, and an adjusting plate 303; the top block 302 is disposed at the top end of the top rod 301, and the adjusting plate 303 is sleeved on the top rod 301 and connected to the top rod 301 through a threaded structure; when supporting the formwork support structure of the beam to be poured, the top block 302 completes the horizontal support of each rectangular tube 15 in the formwork support structure of the beam, the top rod 301 is disposed through the double channel steel support beam 13, and the adjusting plate is disposed on the surface of the double channel steel support beam 13, and the height of the top block 302 can be adjusted by rotating the adjusting plate.

[0055] During implementation, the leveling adjustment device for the double-channel steel support beam is assembled beforehand. Then, based on the location of the first support plate 1, the same elevation position of the other upright is measured with a tape measure. Next, the surface of the assembled disc clip 16 is aligned with the marked elevation line. Then, the first bolt 104 is tightened, a washer is added, and the double nut structure 105 is tightened with an electric screwdriver to ensure that the solid disc clip 16 and the upright are firmly locked. Subsequently, the first flat fastener is firmly fastened under the solid disc, and then the second fastener 18 is firmly fastened under the first fastener 17. Both fasteners and the upright must be firmly fixed. After being fixed in place, the double-channel steel support beam can be placed horizontally.

[0056] In this device, the disc clip 16 is reinforced and fixed with bolts and nuts, which facilitates worker installation and disassembly and ensures that the solid disc clip is firmly locked onto the upright. Both the upper and lower surfaces of the solid disc clip and the double fasteners are flat, allowing the double channel steel support beam 13 to be placed stably on the upper surface of the disc clip 16. Simultaneously, the lower surface of the disc clip 16 and the upper surface of the double fasteners make smooth contact, improving the anti-slip force of the disc clip 16 and ensuring that the double channel steel support beam 13 can better bear the force, supporting the rectangular tubes 15 in a stable state. This device effectively solves the problem of the double channel steel support beam being unable to be placed horizontally due to operator error causing the discs on both sides of the upright at the bottom of the beam to be at different elevations. Furthermore, it is easy to install and disassemble and can be reused multiple times.
