Abstract
The coaxial multiway assembled fastener used for building-up of scaffold in the building construction is composed of vertical shaft, fasteners and sleeve. Its lower fastener, upper fastener and scarf locking sleeve are interlinked on the vertical shaft in turns. Said invention uses a coaxial interlinking technology, not only has the functions of existent fastener, but also can be coaxially rotated, and features multiway rotation. Its structure is simple, flexible and easy to disassemble and assemble.
Description
The coaxial multi-directional shell fastening that uses when organizing the structure scaffold in a kind of building operations.
The fastener that uses when organizing the structure scaffold in the building operations in the past, mainly contain right-angle coupler, three kinds on rotary buckle and bowl snapping head, though above-mentioned fastener pivots in the time of can satisfying group structure scaffold, the requirement of framework, but limit by structure and exist complex structure, time-consuming shortcoming when scaffolding steel pipe is had strict dimensional requirement and dismounting.
The objective of the invention is and will make its repertoire that not only has former fastener by a kind of coaxial package structure Design, and simple in structure in addition, snapping is convenient, and dismounting is quick, time saving and energy saving characteristics.
Accompanying drawing is a structural representation of the present invention, also is that specification digest is with scheming.Among the figure each label be 1 respectively, wedge surface locking sleeve 2, upper fastener 3, down fastener 4, locking key 5, vertical shaft 6, steel pipe 7, go up seaming 8, seaming down.
As shown in the figure, lower fastener (3) is with the lower seaming of upper arc, upper fastener ( 2) with the upper seaming of an arc lower, upper fastener (2) the top high section of one fastener The position is provided with one and locks key, and the present invention is by vertical shaft (5), fastener and sleeve pipe group Become, wherein descend fastener (3) upper fastener (2), wedge surface locking sleeve (1), Be sleeved on successively on the vertical shaft (5), the position dimension that locks key is higher than wedge surface The low spot of locking sleeve (1) is lower than the high point of wedge surface locking sleeve (1).
The course of work of the present invention is as follows: be set in a certain position of scaffold as the present invention after, the steel pipe (6) of taking the structure scaffold is penetrated in the seaming of up and down fastener (2), (3), and wedge surface locking sleeve (1) rotated in the direction of the clock, make its wedge surface and locking key secure fit become rigidity to be connected shape and get final product.
Now provide embodiment in conjunction with the accompanying drawings:
Embodiment is made by the Summoning material, and vertical shaft (5) diameter is 48mm, upper fastener (2), the encasement tube internal diameter 48mm of following fastener (3), wall thickness 6mm, high 45mm, last seaming, following seaming inner arc are circular, the high 32mm of wedge surface locking sleeve (1) low spot, high some degree is 50mm, crosses keyhole diameter 10mm, and the locking key distance is fastener bottom 140mm down, the high 6mm of key, long 20mm.
Claims (2)
- The coaxial multi-directional shell fastening that uses when 1, organizing the structure scaffold in a kind of building operations, form by vertical shaft (5), fastener and sleeve pipe, its architectural feature is bottom fastener (3), upper fastener (2) wedge surface locking sleeve (1) is sleeved on the vertical shaft (5) successively, the position dimension that locks key is higher than the low spot of wedge surface locking sleeve (1), is lower than the high point of wedge surface locking sleeve (1).
- 2, a kind of as the described fastener of claim (1), its characteristics are down the following seaming of fastener (3) with arc on, and upper fastener (2) is with the last seaming of an arc lower.
