Description

Technical Field

[0001] The utility model relates to the technical field of building construction devices, in particular to an adjustable base positioning and fixing structure of a socket-and-spigot type disc-locked steel pipe cantilever scaffold. Background Art

[0002] At present, the socket-type disc-type steel pipe scaffolding is vigorously promoted by the construction authorities. Many local construction authorities have linked the use of the socket-type disc-type steel pipe scaffolding with the project evaluation, and the socket-type disc-type steel pipe scaffolding is becoming more and more widely used. The commonly used scaffolding modes for high-rise buildings are ground scaffolding, cantilever scaffolding, climbing frame, etc. Due to factors such as cost and construction convenience, cantilever scaffolding is often used on floors. When the cantilever scaffolding uses the socket-type disc-type steel pipe scaffolding, there are two main problems: first, the connection plate on the socket-type disc-type steel pipe is a fixed modulus, and the connection plate must be kept at the same horizontal plane during construction; second, the foundation of the pole is an I-beam, and the pole must be set on the center line of the I-beam web to avoid the I-beam from being twisted by eccentric load, while ensuring the modulus.

[0003] Based on many years of production and use experience, many manufacturers and construction units have provided some solutions for the positioning and fixing of the adjustable base of socket-type disc-type steel pipe cantilever scaffolding, such as: adjustable support undercut, thin steel sheet to adjust the elevation, base separate clamp, single-sided clamp, etc. The most advantageous one is a form in which the base and steel plate clamp the I-beam flange plate, one-side qualitative clamp, and the other side separate steel plate bolt fixation. It is effective for the above-mentioned problem one, but for problem two, it is not enough to completely solve the problem of I-beam torsion.

[0004] Then, in the invention patent entitled "A method for installing a column base and a cantilever scaffolding" with the announcement number CN116696028A, buckle plates and connecting sleeves are used, which have limited adjustment of the connection plate elevation and limited locking performance. The strength and stiffness of the single-sided clamp connection with the I-beam flange plate are limited, and the locking performance and the performance of not being subject to unbalanced loads are limited; in the utility model patent entitled "A cantilever scaffolding base device" with the announcement number CN218862059U, a screw rod is used to effectively adjust the connection plate elevation, and a wrapped base plate bolt is also used for double-sided and bidirectional reinforcement, but the bolts are set at the lower part of the flange plate, ignoring the slope of the I-beam flange plate, and its locking performance is limited.

[0005] Therefore, we propose a socket-and-spigot type disc-type steel pipe cantilever scaffolding with an adjustable base positioning and fixing structure. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the utility model provides an adjustable base positioning and fixing structure for a socket-and-spigot type disc-lock type steel pipe cantilever scaffold.

[0011] It is further defined that the adjusting sleeve includes an upper bell-shaped closing section and a lower cylindrical adjusting section, an internal thread is opened in the adjusting section, and a connecting pipe is arranged in the closing section; providing a bell-shaped closing section to connect with the connecting pipe can make the connection more stable, and the connecting pipe will not slide down in the adjusting sleeve.

[0012] It is further defined that two rotating handles are provided on the circumferential surface of the closing section, and the two rotating handles are symmetrically arranged about the center of the closing section; by providing the two rotating handles, it is convenient to rotate the adjusting sleeve to adjust the height of the connecting disk, and the operation is more convenient and labor-saving.

[0013] It is further defined that the bottom of the adjusting rod is fixed to the center of the base plate by welding; the adjusting rod and the base plate are fixed very firmly by welding.
