Description

Technical Field

[0001] This utility model belongs to the field of building structure construction technology, specifically relating to an angle-adjustable support top bracket. Background Technology

[0002] In concrete structure construction, when using cast-in-place technology to form staircases or sloping roof panels, support devices are typically required to maintain their shape. Socket-type disc-lock steel pipe scaffolding, composed of uprights, horizontal bars, diagonal braces, adjustable bases, and adjustable top supports, offers advantages such as high load-bearing capacity, clear force transmission, convenient construction, and quick erection, making it highly popular in cast-in-place structure construction. However, when using socket-type disc-lock steel pipe scaffolding as a support system for staircases or sloping roof panels, and the main joists used for formwork support are double steel pipes, one of the steel pipes may not effectively and evenly bear the force or may be suspended, which is detrimental to controlling the deformation of the staircase or sloping roof panel. Currently, to solve this problem, U-shaped support plates are usually fixed to the top of the support rods with high-strength bolts. However, in actual installation, this method is inconvenient to operate and lacks reliability; once the high-strength bolts loosen, the supporting function of the U-shaped support plate will fail. Therefore, a convenient, stable, and reliable angle-adjustable support top support should be proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an angle-adjustable support top bracket, which addresses the shortcomings of the prior art. Its structure is simple and its design is reasonable. By rotating the adjusting sleeve, the length of the adjustable connecting rod can be adjusted. When the length of the adjustable connecting rod is shortened, the U-shaped support plate can rotate around the hinge axis, causing the U-shaped support plate to tilt. This can meet the support requirements for the main keel of stairs or sloping roof panels with different tilt angles. When the main keel is a double steel pipe, the support rod, U-shaped support plate, and adjustable connecting rod together form a stable and reliable support structure below the double steel pipe, ensuring that each steel pipe in the double steel pipe can effectively and evenly bear the force, which helps control the deformation of stairs or sloping roof panels.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an angle-adjustable support top bracket, characterized in that: it includes a support rod, a U-shaped support plate rotatably mounted on the top of the support rod via a hinge shaft, and an adjustable connecting rod disposed between the support rod and the U-shaped support plate. The support rod includes a threaded rod segment and a smooth shaft segment arranged coaxially. The adjustable connecting rod includes a first threaded rod and a second threaded rod connected by an adjusting sleeve. The bottom end of the first threaded rod is mounted on the smooth shaft segment via a first pin, and the top end of the second threaded rod is mounted on the U-shaped support plate via a second pin.

[0005] The above-mentioned angle-adjustable support top is characterized in that: a first connecting ear plate is provided on the optical axis section, a U-shaped hinge seat is provided on the bottom surface of the U-shaped support plate, a second connecting ear plate is provided on the outer surface of the side plate of the U-shaped support plate, and a U-shaped connecting seat is provided at the bottom end of the first threaded rod and the top end of the second threaded rod.

[0006] The aforementioned angle-adjustable support top is characterized in that: an adjusting nut is installed on the threaded rod segment, and the bottom end of the threaded rod segment is inserted into the support sleeve.

[0007] This utility model has the following advantages compared with the prior art:

[0008] 1. The U-shaped support plate of this utility model is rotatably mounted on the top of the support rod via a hinge shaft, and an adjustable connecting rod is provided between the support rod and the U-shaped support plate. The adjustable connecting rod includes a first threaded rod, a second threaded rod, and an adjusting sleeve. The bottom end of the first threaded rod is mounted on the optical shaft section via a first pin, and the top end of the second threaded rod is mounted on the U-shaped support plate via a second pin. In actual use, the length of the adjustable connecting rod can be adjusted by turning the adjusting sleeve. When the length of the adjustable connecting rod is shortened, the U-shaped support plate can be rotated around the hinge shaft, making the U-shaped support plate tilted. This can meet the support requirements for the main keel of stairs or sloping roof panels with different tilt angles. When the main keel is a double steel pipe, the support rod, U-shaped support plate, and adjustable connecting rod together form a stable and reliable support structure under the double steel pipe, which can ensure that each steel pipe in the double steel pipe can effectively and evenly bear the force, which helps to control the deformation of stairs or sloping roof panels. It is easy to operate and convenient to promote and apply.

[0009] 2. The U-shaped connecting seat located at the bottom end of the first threaded rod is mounted on the first connecting ear plate via the first pin, and the U-shaped connecting seat located at the top end of the second threaded rod is mounted on the second connecting ear plate via the second pin. The connection is flexible and reliable, and it is convenient to adjust and install during construction.

[0010] 3. This utility model has a simple structure, reasonable design, low manufacturing cost, and is easy to promote and apply.

[0011] In summary, this utility model has a simple structure and reasonable design. By turning the adjusting sleeve, the length of the adjustable connecting rod can be adjusted. When the length of the adjustable connecting rod is shortened, the U-shaped support plate can be rotated around the hinge axis, making the U-shaped support plate tilted. This can meet the support requirements of the main keel of stairs or sloping roof panels with different tilt angles. When the main keel is a double steel pipe, the support rod, U-shaped support plate and adjustable connecting rod together form a stable and reliable support structure under the double steel pipe, which can ensure that each steel pipe in the double steel pipe can effectively and evenly bear the force, and help control the deformation of stairs or sloping roof panels.

[0021] like Figure 1 and Figure 2 As shown, this utility model includes a support rod, a U-shaped support plate 2 rotatably mounted on the top of the support rod via a hinge shaft 3, and an adjustable connecting rod disposed between the support rod and the U-shaped support plate 2. The support rod includes a threaded rod section 1-1 and a smooth shaft section 1-2 arranged coaxially. The adjustable connecting rod includes a first threaded rod 4-1 and a second threaded rod 4-2 connected by an adjusting sleeve 4-3. The bottom end of the first threaded rod 4-1 is mounted on the smooth shaft section 1-2 via a first pin 7, and the top end of the second threaded rod 4-2 is mounted on the U-shaped support plate 2 via a second pin 8.

[0022] In this embodiment, the U-shaped support plate 2 is rotatably mounted on the top of the support rod via a hinge shaft 3, and an adjustable connecting rod is provided between the support rod and the U-shaped support plate 2. The adjustable connecting rod includes a first threaded rod 4-1, a second threaded rod 4-2, and an adjusting sleeve 4-3. The bottom end of the first threaded rod 4-1 is mounted on the optical axis section 1-2 via a first pin 7, and the top end of the second threaded rod 4-2 is mounted on the U-shaped support plate 2 via a second pin 8. In actual use, adjustment can be achieved by turning the adjusting sleeve 4-3. The purpose of adjusting the length of the connecting rod is that when the length of the adjustable connecting rod is shortened, it can drive the U-shaped support plate 2 to rotate around the hinge axis 3, so that the U-shaped support plate 2 is in an inclined state. This can meet the support of the main keel of the stairs or sloping roof panels with different inclination angles. When the main keel is a double steel pipe, the support rod, U-shaped support plate 2 and adjustable connecting rod together form a stable and reliable support structure under the double steel pipe. This can ensure that each steel pipe in the double steel pipe can effectively and evenly bear the force, which helps to control the deformation of the stairs or sloping roof panels. It is easy to operate and easy to promote and apply.

[0023] In this embodiment, the tilt angle of the U-shaped support plate 2 ranges from 0° to 60°.

[0024] like Figure 1 and Figure 2 As shown in this embodiment, a first connecting ear plate 1-3 is provided on the optical axis segment 1-2, a U-shaped hinge seat 2-1 is provided on the bottom surface of the U-shaped support plate 2, a second connecting ear plate 2-2 is provided on the outer surface of the side plate of the U-shaped support plate 2, and a U-shaped connecting seat is provided at the bottom end of the first threaded rod 4-1 and the top end of the second threaded rod 4-2.

[0025] In this embodiment, the U-shaped connecting seat located at the bottom end of the first threaded rod 4-1 is mounted on the first connecting ear plate 1-3 via the first pin 7, and the U-shaped connecting seat located at the top end of the second threaded rod 4-2 is mounted on the second connecting ear plate 2-2 via the second pin 8. The connection is flexible and reliable, and it is convenient to adjust and install during construction.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, an adjusting nut 5 is installed on the threaded rod segment 1-1, and the bottom end of the threaded rod segment 1-1 is inserted into the support sleeve 6.

[0027] In this embodiment, the bottom surface of the adjusting nut 5 is always pressed against the top surface of the support sleeve 6. By turning the adjusting nut 5, the length of the bottom end of the threaded rod segment 1-1 inserted into the support sleeve 6 can be adjusted, thereby adjusting the height of the adjustable top support.

[0028] like Figure 1 and Figure 2As shown, in actual use, the bottom end of the threaded rod section 1-1 of the adjustable support top bracket is inserted into the support sleeve 6. The height of the adjustable top bracket is adjusted by turning the adjusting nut 5, and the tilt angle of the U-shaped support plate 2 is adjusted by turning the adjusting sleeve 4-3. This allows the adjustable support top bracket to meet the tilt angle of the staircase or sloping roof panel, thus supporting the main keel of the staircase or sloping roof panel. It is easy to operate, widely used, and easy to promote and apply.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
