Abstract
A connecting cross bar for a support frame or scaffold comprises a cross bar body, a cross bar deadhead and a cross bar pin plate, wherein the cross bar body is 196-2896 mm long and is a round tube, the outer diameter of the cross bar body is 42-48 mm, and the round tube wall thickness of the cross bar body is 2.0-3.5 mm; the cross bar deadhead comprises two tong arms, a base body and a connecting section, the tong arms and the base body are formed in an integrated mode, a groove is formed in the position where the base body is connected with the connecting section, and the cross section of the groove is annular; the connecting section of the cross bar deadhead is inserted into the cross bar body, the cross bar deadhead is connected with the end of the cross bar body, the cross bar pin plate is a wedge-shaped pin plate, and a round hole is formed in the tail end of the pin plate. The connecting cross bar has the advantage that due to the fact that groove and welding double guarantees are adopted, normal work can be conducted even if the cross bar deadhead breaks when weld lacking or faulty soldering occurs during production, and then the situations that a frame body collapses and people fall down to get hurt or die are avoided.
Description
Technical field
The present invention relates to a kind of bracing frame or scaffold member, be specifically related to a kind of bracing frame or scaffold with connect cross bar.
Background technology
Cross bar is a component important in scaffold or bracing frame.During usual bracing frame and scaffold use, cross bar plays a part connecting upright pole transmission horizontal force in support body, also bears vertical load by scaffold floor simultaneously.The quality of its performance directly affects the stability of scaffold or bracing frame and the safety of upper operating personnel.Disc-type steel pipe holder cross bar in the market, its deadhead is connected with the body of rod and adopts direct welding manner to connect, there is the situation of solder skip and rosin joint unavoidably in welding process, weld seam is once snap cross bar will be caused to come off, also all there is the risk come off in the cross bar of bowl fastening type steel pipe scaffold and wheel button steel pipe scaffold, can cause support or connection system for guide rail unstability is caved in or the falling from high altitude of operating personnel.This problem is present in bracing frame both domestic and external and scaffold cross bar product, there is no effective solution at present.
Summary of the invention
The invention provides a kind of cross bar that can not come off, though cross bar in use weld seam snap and cause weld failure, cross bar deadhead and the cross bar body of rod are also connected by groove makes cross bar normally work.Cross bar deadhead and the cross bar body of rod are by bearing 45KN pressure against the ends under groove connection function after tested.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of bracing frame or scaffold with connect cross bar, comprise the cross bar body of rod, cross bar deadhead, cross bar pin plate, described cross bar body of rod length is 196mm ~ 2896mm, the described cross bar body of rod is round tube, the external diameter of the described cross bar body of rod is φ 42mm ~ φ 48mm, and the round tube wall thickness of the described cross bar body of rod is 2.0mm ~ 3.5mm; Described cross bar deadhead comprises two tong arms, pedestal and linkage sections, described tong arm and pedestal are formed in one, described pedestal and linkage section junction are provided with groove, the cross section of described groove is annular, the linkage section of described cross bar deadhead inserts in the cross bar body of rod, and cross bar deadhead is connected with the end of the cross bar body of rod, and described cross bar pin plate is dovetail pin plate, the end of described pin plate is provided with circular port, is provided with rivet in described circular port.
Further, described cross bar body of rod full-length is 196mm or 496mm or 796mm or 1096mm or 1396mm or 1696mm or 1996mm or 2296mm or 2596mm or 2896mm, and separately have other random length sizes, error range is not more than 0.5mm.
