Abstract
Description
Technical Field
[0001] The utility model relates to a novel attachment cantilever beam connection structure, belonging to the technical field of tower cranes. Background Art
[0002] The existing cantilever beam connection form is suitable for the construction industry. The cantilever beam is used in conjunction with attachment to increase the attachment range of the building. The engineering machinery field requires that the cantilever beam can be adjusted in length according to the actual working conditions and is easy to install. The conventional cantilever beam is composed of a beam body, an external joint, an internal joint, an ear seat, a diagonal brace and other devices. The beam body needs to be installed at the location of the embedded parts of the building to extend the attachment range of the building. The internal joint and the external joint are installed on the beam body and the building respectively to strengthen the beam body. The internal joint can be assembled inside the external joint. The length is adjusted by adjusting the internal dimensions of the assembly. After the assembly and adjustment are completed, the external joint and the internal joint are welded together, and then a brace is installed under the beam body to offset the gravity. The brace is consistent with the two joints in structure, one end is connected to the beam body, and the other end is connected to the building. After assembly, it is welded together. In order to fix the cantilever beam, welding operations need to be performed at high altitudes. There are safety risks during the welding process. If the cantilever beam structure is heavy, there are also great difficulties in the hoisting and assembly adjustment stages, which affects the construction period. Summary of the invention
[0003] In order to fix the cantilever beam, welding operations need to be carried out at high altitude. There are safety risks in the welding process. If the cantilever beam structure is heavy, there will be great difficulties in the lifting and assembly and adjustment stages, which will affect the construction period. Therefore, a new type of attached cantilever beam connection structure is designed, which does not require high-altitude welding and assembly adjustments, reduces installation time, and eliminates safety risks during installation.
[0004] The utility model is realized through the following technical scheme: a novel attachment cantilever beam connection structure, comprising ear plate I, ear plate II, steel wire rope, a beam body, a strut, a joint, a round nut and an adjusting screw, wherein the ear plate I and the ear plate II are installed on the embedded parts of the building, the beam body is installed on the ear plate I, the strut is installed on the beam body, the joint is installed on the ear plate II, the strut is connected to the joint through a round nut and an adjusting screw, one end of the steel wire rope is installed on the ear plate reserved on the beam body, and the other end is installed on the building.
[0005] The crossbeam body is installed on the ear plate I through a pin shaft and a vertical pin.
[0006] The length of the support rod can be fine-tuned by adjusting the screw rod, and when adjusted to a suitable length, it can be locked by tightening the round nut.
[0007] Both ends of the steel wire rope are provided with joints and fixed with a plurality of rope clamps.
[0008] The support rod comprises two sections of fixing rods, and the two sections of fixing rods are connected by bolts to form a whole support rod.
[0009] The lengths of the two fixing rods of the support rod can be set according to the site dimensions.
[0010] The beneficial effects of the utility model are as follows: the structure can avoid spot welding and fixing of the support rods at high altitudes, and there is no need to lift the spot-welded structure as a whole to the ground for complete welding. The length of the support rods can be directly adjusted by adjusting the screw rods, which effectively solves the installation difficulties caused by welding and reduces the installation time. The installation efficiency is further improved by replacing the lower support rods with steel wire ropes. BRIEF DESCRIPTION OF THE DRAWINGS
