Abstract
The utility model discloses a scaffold cross rod with a steplessly-adjusted length. The scaffold cross rod comprises a rod piece, insertion heads and a detachable telescoping device, wherein the insertion heads are respectively welded at the two ends of the rob piece; the detachable telescoping device comprises an outer sleeve, an inner bushing rod and a detachable fastening device; the inner bushing rod is matched with the outer sleeve; the rod piece is divided into two sections; the dividing position of one section is fixedly connected with the inner bushing rod to form a whole; the dividing position of the other section is integrally connected with the outer sleeve; the inner bushing rod is fixedly connected with the outer sleeve to form a whole through the detachable fastening device. The scaffold cross rod is simple in structure and suitable for scaffold erecting places in the construction industry.
Description
Technical field
The utility model relates to the scaffold cross bar of stepless adjusting length.
Background technology
Scaffold for building mainly by vertical rod, cross bar is crisscross builds, and wherein in vertical rod, is connected with wheel button dish, crossbar end is welded with the cross bar plug matched with the button hole of taking turns the button dish, the cross bar plug is plugged into to wheel and buckles the button hole of dish and form scaffold.As: application number is 01219160.4, the utility model patent that notification number is CN2568752, a kind of " direct-insertion type double-self-locking multifunctional scaffold " disclosed, it comprises vertical rod and cross bar, in vertical rod, there is vertically spaced wheel button dish, in wheel button dish, be provided with taper slotted hole that match with the plug of cross bar, equally distributed.This multifunction scaffold simple structure, be convenient to Fast Installation and dismounting.
In prior art, scaffold cross bar length is all fixed, when the job site actual conditions need to regulate montant mutual apart from the time, the fixing cross bar of length can not satisfy the demands.
Summary of the invention
Technical problem to be solved in the utility model is, but a kind of scaffold cross bar of stepless adjusting length as required is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of scaffold cross bar of stepless adjusting length comprises rod member; Plug, this plug is welded on respectively the two ends of rod member; Removable stretching device, this removable stretching device comprise outer tube, with suitable interior loop bar and the removable fastener of this outer tube, this rod member is divided into two sections, wherein section office and the interior loop bar of one section fix as one, the office of cutting of another section is connected with the outer tube one, and removable fastener fixes as one interior loop bar and outer tube.
Beneficial effect: in technique scheme, because rod member is divided into two sections and respectively on the affixed interior loop bar and outer tube be socketed, when needs shorten the total length of rod member, the lap length of interior loop bar and outer tube socket is strengthened, by removable fastener, it is fixed as one again, the stepless rod member total length of having shortened; When needs lengthen the total length of rod member, unclamp removable fastener, the lap length of interior loop bar and outer tube socket is dwindled, then by removable fastener, it is fixed as one, the stepless total length that lengthens rod member; Solve in sum the technical problem of step-less adjustment cross bar total length.
As the concrete scheme to technique scheme, removable fastener comprises N tapped through hole being located at described outer tube tube wall and the threaded fastener matched with it, N >=1.When the demand of the total length according to rod member is socketed interior loop bar into after in outer tube, by threaded fastener precession tapped through hole, until hold out against interior loop bar, this mode is simple to operate, and mounting or dismounting easily.
As the concrete scheme to technique scheme, this is affixed is welding, and it is that outer tube and another section are formed in one that this one is connected.This concrete scheme makes rod member more firm.
The accompanying drawing explanation
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model;
Fig. 2 is installation drawing of the present utility model;
Fig. 3 is the scheme of installation of the utility model on scaffold.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Referring to Fig. 1, the scaffold cross bar of stepless adjusting length of the present utility model, comprise rod member 2; Plug 1, removable stretching device, this removable stretching device comprise outer tube 31, with suitable interior loop bar 32 and the removable fastener of this outer tube 31, rod member 2 is divided into two sections, wherein section office and the interior loop bar 32 of one section 21 are welded as a whole, section office and the outer tube 31 of another section 22 are integrated part, and removable fastener comprises 2 tapped through holes 312 of being located at outer tube 31 tube walls and the threaded fastener matched with it, N >=1
Referring to Fig. 2, plug 1 is welded on respectively the two ends of rod member 2.When determine the total length of cross bar according to the distance of scaffold upright rod, by interior loop bar 32 covers tap into outer tube 31 interior after, by threaded fastener 5 precession tapped through holes 312, until hold out against interior loop bar 32.
Referring to Fig. 3, during installation, the plug 1 that is welded on rod member 2 two ends injects buckleing in dish of scaffold upright rod 6.
