Abstract
The invention discloses a scaffolding cross bar allowing the length to be adjusted in a stepless mode. The scaffolding cross bar comprises a rod piece, insert heads and a detachable telescopic device, wherein the insert heads are welded to the two ends of the rod piece respectively. The detachable telescopic device comprises an outer sleeve, an inner loop bar and a detachable fastening device, wherein the inner loop bar is match with the outer sleeve. The rod piece is divided into two segments, the position where one segment is divided and the inner loop bar are fixedly connected into a whole, and the position where the other segment is divided and the outer sleeve are connected in an integrate mode. The inner loop bar and the outer sleeve are fixedly connected into a whole through the detachable fastening device. The scaffolding cross bar is simple in structure and used on the occasions where scaffoldings are built of the construction industry.
Description
Technical field
The present invention 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, notification number is the patent of invention of CN2568752, a kind of " direct-insertion type double-self-locking multifunctional scaffold " disclosed, it comprises vertical rod and cross bar, in vertical rod, have vertically spaced wheel button dish, be provided with taper slotted hole that match with the plug of cross bar, equally distributed in wheel button dish.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 by this invention is, but a kind of scaffold cross bar of stepless adjusting length as required is provided.
The technical solution adopted for the present invention to solve the technical problems is: 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 a 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 a concrete scheme to technique scheme, this is affixed for 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 invention;
Fig. 2 is installation drawing of the present invention.
Fig. 3 is the installation drawing of the present invention on scaffold.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Referring to Fig. 1, the scaffold cross bar of stepless adjusting length of the present invention, 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 according to the distance of scaffold upright rod, determining the total length of cross bar, 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.
