Description

Technical Field

[0001] The utility model relates to the field of cantilever beam scaffolding, in particular to a connection mechanism of a cantilever beam of a cantilever frame. Background Art

[0002] In the prior art, it is often used to pre-weld positioning poles, such as steel bars or short pipes, on the I-beams. When the scaffold is erected, the scaffolding poles are placed outside the positioning poles. However, during the welding process, the positioning poles are prone to tilt or are not welded firmly, so that the positioning poles cannot be used to properly connect with the scaffolding poles during erection, affecting the erection of the cantilever beam scaffold. At the same time, it is also required to use steel wire ropes to unload the load at the outer poles of the I-beams. In order to avoid the steel wire ropes from directly contacting the steel beams and being broken, they must be isolated with rubber or other materials, which is cumbersome and unreliable to install.

[0003] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. Utility Model Content

[0009] Preferably, the first connecting plate and the second connecting plate are both provided with chamfers at one end away from the positioning plate.

[0010] Preferably, the diameter of the second positioning hole is larger than the diameter of the first positioning hole.

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 2As shown, the connection mechanism of the cantilever frame cantilever beam includes a positioning plate 10, a first connecting plate 20, a second connecting plate 30 and a connecting block 40 for sleeved on the I-beam a. The first connecting plate 20 and the second connecting plate 30 are respectively connected integrally on both sides of the width direction of the connecting block 40, and the first connecting plate 20 and the second connecting plate 30 are arranged opposite to each other. The positioning plate 10 is integrally connected to the end faces of the first connecting plate 20 and the second connecting plate 30 away from the connecting block 40. A first positioning hole 11 is provided on the positioning plate 10, and a second positioning hole 41 is provided on the connecting block 40 at a position corresponding to the position below the first positioning hole 11. The second positioning hole 41 is a through hole, and the first positioning hole 11 is coaxially arranged with the second positioning hole 41. A positioning bolt hole 42 for fixing the connecting block 40 on the I-beam a is provided on the side of the connecting block 40 corresponding to the second positioning hole 41.

[0022] In this embodiment, the connecting block 40 is a rectangular frame and can be directly mounted on the I-beam a. The connecting block 40 is moved to a corresponding fixed position and is locked on the I-beam a by using conventional hexagonal bolts through the positioning bolt holes 42. Then, the vertical pole b can pass through the first positioning hole 11 and the second positioning hole 41 in sequence to contact the I-beam a, which can effectively ensure the positioning connection between the vertical pole b and the I-beam a and facilitate the erection of the steel cantilever beam scaffolding.

[0023] As a preferred mode of this embodiment, it also includes a pin 50. In this embodiment, the pin 50 is a conventional pin sensor. A fixing hole is provided at one end of the pin 50 away from the first pin hole, and a cotter pin is connected to the fixing hole to prevent the pin 50 from falling out of the pin hole. A first pin hole is provided on the first connecting plate 20, and a second pin hole is provided on the second connecting plate 30. The first pin hole and the second pin hole are coaxially arranged. The pin 5 passes through the first pin hole and the second pin hole and is fixed to the connecting mechanism. The position of the pin 50 between the first pin hole and the second pin hole can be used for connecting a wire rope. The outer contour of the pin 50 is circular. The wire rope is connected to the pin to prevent the wire rope from being connected to the I-beam and being cut by the I-beam. The pin 50 can be moved at a position corresponding to the first pin hole and the second pin hole of the pin 50 to avoid interference with other vertical poles. A pin-type load sensor can also be used as a pin to monitor the tension of the lifting and unloading wire rope in real time, which is used to verify the accuracy of load verification or overload warning. It is particularly suitable for monitoring the stress of special parts of buildings, such as building corners (yang corners), balconies, and cantilever beams in stairwells.

[0024] As a preferred mode of this embodiment, the first connecting plate 20 and the second connecting plate 30 are both provided with a chamfer c at one end away from the positioning plate 10. By providing the chamfer c, it is prevented that the first connecting plate 20 and the second connecting plate 30 are damaged or scratched by collision during use.

[0025] As a preferred embodiment of this embodiment, the diameter of the second positioning hole 41 is larger than the diameter of the first positioning hole 11, so as to facilitate the installation of the vertical pole b.

[0026] In summary, the connecting mechanism can be moved on the I-beam, and is simple to install and easy to use. It can ensure the connection between the vertical rod b and the I-beam a. The vertical rod b passes through two positioning holes and directly contacts the I-beam a, which can directly transfer the load, which is more conducive to load transfer, and the connecting mechanism can be reused to save resources.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
