Description

Technical Field

[0001] The utility model belongs to the technical direction of a formwork support frame system, and specifically relates to a shark-tooth type disc buckle cross bar. Background Art

[0002] In the formwork support system, the buckle frame has become the first choice for efficient structural construction in recent years. The specific process principle is: different specifications of steel pipes are used to form the frame's vertical poles, horizontal poles, diagonal poles and other components. The vertical poles mainly bear the vertical construction load. All vertical poles are connected by horizontal poles and diagonal poles to form a complete support system as a frame to support the formwork project. Among them, the horizontal bar is a horizontal component in the support system, connecting two adjacent vertical poles, bearing the lateral force of the frame (including tension and pressure), which can increase the overall stability of the support system.

[0003] The buckle frame has a fixed crossbar modulus (spacing is a multiple of 300mm). During the erection process, for spaces that are not in its modulus, there are the following defects: the frame cannot be erected in spaces that are not in its modulus, the crossbars cannot be used, and steel pipe fasteners are usually used for connection; the mix of different frames leads to a decrease in the integrity of the formwork frame, and the frame entity does not match the calculation model, and the safety is questionable. The fixed modulus of the buckle crossbar causes the vertical poles at the bottom of the beam to deviate from the center of the bottom of the beam or even cannot be set.

[0004] The utility model solves the problem of connecting the cross bars when the disc buckle uprights are non-modular, and develops a shark-tooth type disc buckle cross bar. Utility Model Content

[0007] The utility model further describes that a row of dense grooves is provided on one side of the long groove, and the internal connecting rod of the shark tooth can move in the long groove.

[0008] The utility model further illustrates that the number of the shark teeth 8 is equal to the number of the dense grooves, and the shark teeth are rotated between the dense grooves.

[0009] The utility model further describes that the groove sleeve rod and one end of the shark tooth internal connecting rod are respectively welded with buckle joints, a through groove is provided in the middle of the buckle joint, a buckle lock is placed inside the through groove, and a card slot is provided on one side of the buckle joint.

[0010] The utility model further illustrates that a connecting disk is fixed on one side of the card slot, a disk hole is arranged on the connecting disk, the disk hole is aligned with the through slot, and a buckle lock is inserted into the disk hole.

[0011] The utility model further illustrates that a column is fixed in the middle of the connecting disk, and the rotation of the column drives the rotation of the connecting disk.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model, by providing shark teeth and dense grooves, makes the connection of the disc buckle cross bar not limited by the module. The new connection cross bar is simple to construct and has a fast connection speed. It solves the problem of cross bar connection when the disc buckle vertical bars are non-module, and can make the arrangement of the disc buckle vertical bars more reasonable and not limited by the cross bar connection module.
