The proper position of the connecting body is provided with a convex baffling strip, a fastening ring is sheathed between the baffling strip and the convex ring, and the upper end of the fastening ring is helical. The inner side wall is provided with a concave ditch, the lower end of the concave ditch is provided with an arc-shaped containing slot, and both ends of the transverse rod are provided with clamping portions which are placed in the containing slot. The upper end o the fastening ring and the lower end of the baffling strip are mutually supported to form a firm scaffold.

Description

Scaffolding structure

A kind of scaffold (also claiming scaffold) structure belongs to building scaffold field.

The overlap joint multipurpose screw of existing scaffold or threaded sleeve screw togather locking, realize that the number body of rod overlaps the upright purpose of group mutually, but these scaffold buildings are in the open, because of being subjected to wind or because of after the people makes it to rock above standing in, very easily cause screw or sleeve to move back buckleing, and make between each body of rod connection loosing or get loose, directly influence construction workman's personal safety, simultaneously, when assembling or dismounting scaffold, must be with instruments such as spanner or screwdrivers with screw means or spiral shell pine, not convenient really when assembling or dismounting scaffold in actual use, thereby the new project organization of scaffold has been proposed.

The purpose of this utility model provides a kind of structure-improved of scaffold, plant one convergence body between up-and-down rod, establish fixedly a bulge loop and a bunching ring that can upper and lower activity on the convergence body, the blocking part of yardarm limit inverted cone shape is placed between bulge loop and bunching ring, and bunching ring moves down and screws, quite convenient in the assembling, and cross bar and the unlikely loosening or slippage of convergence body.

The purpose of this utility model can realize by following measure, respectively be provided with for straight-bar insertion section and shrinking section at the two ends of this convergence body, in being provided with, the upper end of shrinking section have tank and interior sidewall surface to have the bulge loop of suitable curved arc degree, convex with blend stop in the convergence body appropriate location, activity is nested with the bunching ring that periphery is provided with bossy body between blend stop and bulge loop, the last ora terminalis of bunching ring is a helical form, its interior sidewall surface is provided with chase, its lower end, inwall side is provided with the tank of suitable curved arc degree, the cross bar two ends are the blocking part of inverted cone shape, the blocking part of cross bar can be put in the tank of bulge loop and bunching ring, bunching ring can change to a side, it on the lower surface of ora terminalis and blend stop mutual urgent against.

The utility model has the advantages that: do not become flexible or slippage because of wind and people stand, the assembly and disassembly facility is difficult for losing parts, and is safe and reliable.

Now contrasting accompanying drawing is described in detail as follows the utility model:

The scaffolding structure of the utility model (Fig. 1, Fig. 2) is at the upright convergence body 2 of 1 of two straight-bar group, and at a side joint cross bar 17 of convergence body 2, is assembled into the scaffolding structure that needs height; These convergence body 2 two ends are respectively equipped with inserts section 3 and shrinking section 5, and on insertion section 3 and shrinking section 5, be provided with locking hole 4,6 (locking hole 6 be can't see in the drawings), after pegging graft, lock with screw with straight-bar 1, be provided with in the upper end of shrinking section 5 that tank 8 and interior sidewall surface are arranged in one is the bulge loop 7 of curved arc degree, again in the protruding tool of convergence body 2 appropriate locations with blend stop 9, be with the bunching ring 10 that outer periphery has the bossy body 11 of easy rotation at

blend stop

9 and 7 slips of bulge loop, the last ora terminalis 12 of bunching ring 10 is a helical form, side wall surface is provided with a upright chase 13 within it, is provided with the tank 14 of suitable curved arc degree in the interior sidewall surface lower end; Be provided with a stops 15 in order to avoid bunching ring 10 comes off in the top of blend stop 9, the two ends of this cross bar 17 are the blocking part 18 of inverted cone shape, like this can be with straight-bar 1 and cross bar 17 mutually firm sockets; Convergence body 2 bottoms bottom are provided with flat board 16, so that can steadily support the scaffold after the assembling.(Fig. 2 when the workman scaffolds erecting, Fig. 4, Fig. 5, Fig. 6), can socket arranged on the insertion section 3 of dull and stereotyped 16 convergence body 2 with straight-bar 1, can be plugged on the shrinking section 5 of another convergence body 2 simultaneously again in the insertion section 3 of straight-bar 1, locked with screw, so that with the vertically unlimited extension of straight-bar 1, the chase 13 of bunching ring 10 is aimed at blend stop 9, bunching ring 10 is up moved, again the blocking part 18 of cross bar 17 is put into the tank 8 of bulge loop 7, bunching ring 10 moved down and rotate (Fig. 7 to a side, Fig. 8, Fig. 9) make cross bar 17 blocking parts 18 be put in the tank 14 of bunching ring 10, the scaffold assembling of stable strong is promptly finished in the ora terminalis 12 urgent lower surfaces that are butted on blend stop 9 on it.

Because the utility model is when setting up cross bar 17, it is the tank 14 of directly blocking part 18 of cross bar 17 being put into bulge loop 7 and bunching ring 10, bunching ring 10 rotation screws togather the urgent conflict in lower surface that makes ora terminalis 12 and blend stop 9 it on, can be in convergence body 2 with cross bar 17 strong fixs, scaffold is subjected to produce the situation of rocking in wind or the use, and its bunching ring is unlikely to get loose; Therefore, steadiness when no matter scaffold of the present utility model is assembled after operating performance or the assembling, all reach suitable convenience and purpose of safety, really reached the use effect of expection, the above concrete structure of the present utility model, not only in like product, do not find, before application, do not disclose yet.

Claims
