Abstract

The utility model relates to a joint used for connecting a steel tube when erecting a steel pipe scaffold, comprising a cube, a lune connecting panel, a stiffening plate, a straight connecting panel and a cross scissors plate. The joint can be simultaneously connected with a steel tube with six directions, wherein, one joint can be connected with at best nine steel tubes comprising two upright stanchions, three rails and four inclined struts, and which can save more than by ten percent usage amounts of the steel tubes, and the usage amount of the joint is two fifth of the usage amount of a fastener of a fastener type scaffold. The transmission of the force is a shearing force which causes the transmission to be more reasonable. The steel tube can be made into a standardized length so as to standardize the scaffold bar member and enable the scaffold erect orderly, beautifully and conveniently and be convenient for management and examination, and the erection of scaffold which is not based on the requirement must be stopped. The stack and transportation of the steel tube are more convenient and easier and the installation is simple, safe and flexible, various scaffolds can be erected, more particularly an indoor scaffold cam be erected conveniently.

Description

Joint

Technical field

The utility model relates to a kind of connector that steel pipe scaffold is used of setting up, and the steel pipe that can finish six direction with a connector connects, and specifically is a kind of joint.

Background technology

Used scaffold in the construction of structure, great majority are to adopt fastener type steel pipe scaffold.The connection of steel pipe is finished by fastener, vertical rod in the scaffold connected with being connected by cruciform fastening for falsework of leger, little cross bar is on leger, also connect by cruciform fastening for falsework, the butt joint of the butt joint of vertical rod and vertical rod, leger and leger is connected with word deduction, also will use rotary buckle when setting up the scissors support.Vertical rod does not directly contact with cross bar when vertical rod is connected with cross bar, and the load that acts on during construction on the cross bar is delivered in the vertical rod by cruciform fastening for falsework, and the transmission of its power is that the frictional force that produces when holding cross bar and vertical rod with a firm grip by fastener is finished.The length of steel pipe because steel pipe is longer, is unfit to do inner scaffold generally at 6 meters (except little cross bars).When scaffold was installed, the vertical transport of steel pipe was very inconvenient, can not be with hanging scaffold or cage transportation, and great majority are vertical transport of finishing steel pipe by installation personnel with the pulling of rope, installation rate is slower.The butt joint of vertical rod is the comparison difficulty, also be dangerous, installation personnel stands on the steel pipe in high-altitude, about under the situation having no backing, can not move steel pipes long with 6 meters, 23 kiloponds vertically lift, finish the butt joint of steel pipe, this work is to general constructor, do not say on the shelf that stands in the high-altitude, be exactly on ground, can vertically lift by steel pipes long with 6 meters, 23 kiloponds, be not easy very much, be on the high-level shelf still more, its difficulty and danger are well imagined.So the scaffolder belongs to special work post, the personnel that scaffold is installed must pass through the professional technique training, could be on duty behind the certificate that qualifies.No matter be the connection between vertical rod, leger, little cross bar, the scissors support, all be to lean on the bond stress of fastener to realize, the position of fastener card pipe is also uncertain, all can change the position at every turn, and during each fastener card pipe, can on pipe, leave a trace damage pipe and deface paint, so neither attractive in appearance, shortened application life of steel pipe again.For guaranteeing to connect reliably, prevent scurrying out of steel pipe, the length of little cross bar is grown 60 centimetres to 70 centimetres than the horizontal spacing of vertical rod, and the leger in the scaffold end also will grow 30 centimetres to 40 centimetres, and is neither attractive in appearance, again waste material.

Summary of the invention

For the transfer mode that changes existing fastener power and the mounting method of scaffold, the utility model provides a kind of joint, and it is extremely convenient that this joint is connected with steel pipe, and the installation of scaffold is simple, speed is fast, power transmission reliably, safety.

The technical scheme in the invention for solving the technical problem is: a kind of joint that is used to connect steel pipe scaffold comprises by square, arc junction plate, stiffener, direct-connected fishplate bar, cross scissors plate and forming.Described arc junction plate and stiffener are supporting, a hole that is shaped on screw thread is arranged on arc junction plate, arc junction plate is responsible for connecting steel pipe and is transmitted horizontal force and vertical force, control simultaneously the displacement of steel pipe again with stiffener, and with the Load Transfer that produces on the cross bar to vertical rod, the transmission of its power is a shearing force.A hole is arranged on the described direct-connected fishplate bar, be connected with brace, be used for builder's jack by handle.On the described cross scissors plate four holes are arranged, be connected with bridging, be used for to be provided with the scaffold of bridging by handle.Respectively there is a hole the same side at described steel pipe two ends, when steel pipe socket after on the arc junction plate, bolt passed on hole on the steel pipe and the arc junction plate of precession be shaped in the hole of screw thread, steel pipe and joint are linked together, changed the transfer mode of power and the mounting method of scaffold.

The beneficial effects of the utility model are: change the transmission of power into shearing force by frictional force, the transmission of exerting all one's strength is more reasonable, and scaffolding structure is stable more, safety.Can be according to the requirement of safety operation, with vertical rod, leger, little cross bar, bridging, brace are made full-length, paint different colors, make the standardization of scaffold rod member.So both improved the Degree of Safety of scaffold, make again the scaffold of setting up neat, attractive in appearance, be convenient to management and check, stop to set up scaffold not according to operational procedure.The length of steel pipe has been lacked, and is in light weight, and the stacking of steel pipe, transportation, installation ratio are easier to, make things convenient for, simple, safety, do not need the special training scaffolder, and general constructor just can install.Can set up diversified scaffold (comprising inner scaffold).This joint can connect the steel pipe of 6 directions simultaneously, and the multipotency in tie point place connects 9 rod members, has reduced the use amount of steel pipe and joint, can save the use amount of steel pipe more than 10, and the joint usage quantity is 2/5ths of a fastener usage quantity.The scaffold standardization also can make the scaffold floor standardization, replaces the bamboo scaffold floor with Steel scaffold board, but scaffold floor application life increases the number of turnover of scaffold floor, can reduce the use cost of scaffold floor.
