Abstract
The utility model relates to a steel tube scaffolding bridging connecting piece. Wherein, two groups of hoops are articulated on the connecting piece; lugs are arranged on the hoops; ring-shaped handle levers are articulated with the lugs; spacing holes are opened on the handle levers; lug bosses are welded on the hoops and an inner hole is positioned in the lug bosses and is provided with T-shaped stop bolts; the stop bolts are cooperated with the spacing holes of the handle levers by gaps. The utility model has simple structure and unnecessary of using auxiliary tools in installing and disassembling as well as convenient and safe operation, which is used in the installation of the steel tube scaffolding bridging.
Description
(1) technical field
The utility model relates to the steel pipe scaffold bridging, particularly the steel pipe scaffold bridging connecting piece.
(2) background technology
Existing steel pipe scaffold bridging connecting piece adopts fastener, by bolt steel pipe is clamped, when built is installed, the operative employee entangles steel pipe to fastener, tights a bolt with wrench, and its clamping force is wayward, because of the people suitable, twist too tight screw thread rapid wear, clamping force is not enough when twisting tightly, stays accident potential; The constructor stands on the support body mounting or dismounting one place and will use the wrench operation just can finish for more than ten times, and working security is poor, and workload is big, and efficient is low; Because the building operations duration is longer, the wind and weather bolt can get rusty, and causes dismounting next time difficulty; Fastener and bolt are dispersed structures in addition, use and handling process in easily lose and damage, cause the use cost increase.
(3) summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of linkage, have simple in structure, easy-to-operate.
The technical scheme in the invention for solving the technical problem is: have two groups of iron hoops hinged on the connector, be welded with lug on the iron hoop, have annular hand grip and lug hinged, described handle has spacing hole, be welded with boss on the iron hoop, an endoporus is arranged in the boss, "T"-shaped caging bolt is housed.Described caging bolt and handle spacing hole matched in clearance.
The beneficial effects of the utility model are that the connector iron hoop is embraced steel pipe and closed up, and the handle spacing hole is pressed into boss, and "T"-shaped caging bolt rotates 90 °, pin the spacing hole on the handle, make handle be in the position of pass, it is simple in structure, aid is not used in installation and removal, and is convenient, job safety.
(4) description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view
Among the figure: 1, iron hoop, 2, lug, 3, annular hand grip, 4, spacing hole, 5, boss, 6, T shape caging bolt, 7, iron hoop connects hinge
(5) specific embodiment
The specific embodiment: connector has (1) two group on iron hoop, two groups of iron hoops (1) connect hinge (7) by iron hoop and connect, embracing steel pipe closes up, be welded with lug (2) on the iron hoop (1), there are annular hand grip (3) and lug (2) hinged, iron hoop is welded with boss on (1), boss has an endoporus in (5), "T"-shaped caging bolt (6) is housed, and handle has spacing hole on (3), and the handle spacing hole is pressed into boss (5), rotate (6) 90 ° of "T"-shaped caging bolts, pin the spacing hole on the handle (3), make handle (3) be in the position of pass, the spacing hole matched in clearance on "T"-shaped caging bolt (6) and the handle (3).
Reverse (6) 90 ° of "T"-shaped caging bolts draw back the dismounting of handle (3) steel pipe and connector, extract steel pipe out.
Claims (2)
1, steel pipe scaffold bridging connecting piece is characterized in that: two groups of iron hoops are hinged on the connector, are welded with lug on the described iron hoop, have annular hand grip and described lug hinged, described annular hand grip has spacing hole, is welded with boss on the iron hoop, one endoporus is arranged in the boss, "T"-shaped caging bolt is arranged.
