Abstract
The invention provides a self-locking type scaffold welding-free connection device which is used for being connected with a horizontal transverse support rod, vertical inclined support rods and a vertical rod. The self-locking type scaffold welding-free connecting device comprises a socket base seat, flat end knock pin threaded rods and a fixed part. Trapezoid conical heads are connected on four direction planes of the socket base seat in an evenly distributed mode. A circular hole is formed in the center of the socket base seat and used for being connected with the vertical rod in a sleeved mode. The trapezoid conical heads are in a shape with a narrow interior, a wide exterior, a narrow top and a wide bottom. Threaded holes along the horizontal direction are formed in the vertical centers of the trapezoid conical heads. The flat end knock pin threaded rods are inserted into the threaded holes. Flat ends of the flat end knock pin threaded rods can be inserted into the circular hole of the socket base seat and attached to the vertical rod inside the circular hole.

But the socket joint pedestal of the type scaffold must be welded in vertical rod, in the time of in actual use need to other positions increase the socket joint pedestal temporarily in vertical rod, the mode of this welding socket joint pedestal is inconvenience very, and the type scaffold socket joint pedestal can only be connected with the cross bar of horizontal direction, can't satisfy that vertical rod connects horizontal cross bar and the vertically requirement of inclined support bar simultaneously in the construction of large-scale high-supported formwork, thereby cause certain use limitation.
Summary of the invention
The objective of the invention is to propose a kind of self-locking scaffold and exempt to be welded to connect device, can exempt from welding and be fastened on the vertical rod optional position, and can realize being connected of vertical rod and cross bar, horizontal cross bar, vertical inclined support bar.
For achieving the above object, the present invention proposes a kind of self-locking scaffold fastening apparatus, be used for being fixedly connected with horizontal cross cradling piece, vertically inclined support bar and vertical rod, it comprises that socket joint pedestal, flush end stop top screw rod and fixture, described socket joint pedestal comprises that on the four direction plane, equally distributed four connect trapezoidal coneheads, and socket joint pedestal center is circular port, is used for the socket vertical rod, being shaped as of trapezoidal conehead is inner narrow outer wide, up-narrow and down-wide; All there is the silk hole of horizontal direction the vertical center of trapezoidal conehead; Described flush end stops the top screw rod and is screwed in a hole of trapezoidal conehead, flush end stops the flush end section of top screw rod and contacts with vertical rod in socket joint pedestal circular port, by unclamping and tighten described flush end and stop the top screw rod, the locked position of the described socket joint pedestal of capable of regulating in described vertical rod.
Described trapezoidal conehead is provided with the silk hole of horizontal direction, wears described vertical inclined support bar and a hole by described fixture, thereby vertical inclined support bar is fixedly connected on the socket joint pedestal.
Further, in above-mentioned self-locking scaffold exempted to be welded to connect device, an end of described horizontal direction cradling piece was provided with the trapezoidal groove adaptive with described trapezoidal conehead.
Further, in above-mentioned self-locking scaffold exempts to be welded to connect device, described fixture is the T-shaped screw rod with nut, and described vertical inclined support bar one end is provided with fixing hole, and the aperture of the fixing hole of the bar footpath of described T-shaped screw rod and vertical inclined support bar one end is suitable.
Further, in above-mentioned self-locking scaffold exempted to be welded to connect device, described fixture also can be screw or steady pin.
Further, in above-mentioned self-locking scaffold exempted to be welded to connect device, described socket joint pedestal was steel casting.
Self-locking scaffold of the present invention exempts to be welded to connect device can conveniently adjust the locked position of described socket joint pedestal in vertical rod, avoided the trouble of welding, and realized being connected of vertical rod and horizontal direction cradling piece and a plurality of angles of vertical inclined support bar and position, it is simple in structure, saved construction material and mounting or dismounting time.
