Abstract

The utility model relates to a stayed movable scaffold, which is composed of vertical rods, a screw rod, a balance bar, a rope winder, a lifting steel cable, an angle iron bracket, a scaffold board, a supporting frame, a supporting rod, and a safety chain. The utility model is characterized in that the bottoms of the vertical rods are connected with the supporting frame; the upper ends of the two vertical rods are respectively connected with the lower ends of the two vertical rods by the balance bar and the supporting rod; the screw rod is arranged between the balance bar and the supporting rod; the rope winder is fixed to the balance bar; the lifting steel cable pulls both ends of a transversal rod of the scaffold board in incline. By twisting the rope winder or rocking a handle, the utility model enables the scaffold board to lift up and down without strapping bamboo layer by layer and laying the scaffold board, and has the advantages time saving, labor saving, and material saving. Making use of the stayed steel cable to lift the transverse rod of the scaffold board, the utility model has the advantages of compact structure and convenient assembly and disassembly, and can be operated by general workers. Provided with the safety chain, the utility model also has the advantages of good reliability and high safety factor, and is a practical and novel scaffold in construction works at present.

Description

The cable-stayed type jenny scaffold

The utility model relates to a kind of cable-stayed type jenny scaffold.

The external rendering of highrise building all needs to use scaffold, and present scaffold mostly adopts mao bamboon to tie up or the steel pipe snapping forms, and mao bamboon is tied up the scaffold that forms with the steel pipe snapping, all fix, be difficult for regulating or arbitrarily lifting, use inconvenient, waste of manpower and material resources, the cost height.

The purpose of this utility model is produced a kind of scaffold exactly, and arbitrarily the lift adjustment height is installed and removed convenient, laborsaving, material saving.

The utility model is achieved like this, it is made up of vertical rod, screw mandrel, balancing pole, balancing pole fastener, safety fastener, ropewinder, lifting wire rope, load-bearing fastener, angle iron bracket, scaffold floor cross bar, scaffold floor, bracing frame, support fastener.The bottom of vertical rod connects a bracing frame, supporting fastener is fastened on bracing frame in the vertical rod, upper end between per two vertical rods is connected by balancing pole, the balancing pole fastener with the balancing pole fastening in vertical rod upper end, lower end between per two vertical rods is connected by pressure pin, the two ends of pressure pin are angle iron bracket, by the lower end of load-bearing fastener fastening in vertical rod, traverse the scaffold floor cross bar on the angle iron bracket, scaffold floor is placed on the scaffold floor cross bar, the lifting wire rope mitered is lived the two ends of scaffold floor cross bar, can be by ropewinder with the scaffold floor oscilaltion, and ropewinder is fixed on the balancing pole, be connected with a rhizoid bar between pressure pin and the balancing pole, there is a handle upper end of screw mandrel, and turning handle can have two insurance chains with the scaffold floor oscilaltion between safety fastener and the angle iron bracket, when scaffold floor is elevated to suitable position, available angle iron bracket is held, and will insure chain and fix, can be on scaffold floor trouble free service.Bracing frame of the present utility model is folding cross backing plate, and vertical rod is fixed on the backing plate center, and backing plate is collapsible, and the end points of the backing plate support bar that is connected through the hinge, support bar get up fastening supporting on the fastener, play the effect of fixedly vertical rod.Angle iron bracket of the present utility model, some hook reinforcing bars of inboard welding guarantee that the scaffold floor cross bar can not slide, notch board of edge welding of angle iron bracket, the load-bearing fastener fastens notch board.There is a fixing hole centre of angle iron bracket, and two ends are the chain cylindrical void, connects the insurance chain.

The utility model is by the twist ropewinder and shake handle, the scaffold floor oscilaltion can be need not to prick layer by layer frame, the shop scaffolding board, save time, saving of labor, material saving, adopt the cable-stayed type wire rope to hang scaffold cross bar, compact conformation, mounting or dismounting are convenient, general workman all can operate, and the insurance chain is housed, and unfailing performance is good, the safety factor height is a kind of new type scaffold practical in the present construction work.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing 1 is a work schematic diagram of the present utility model.

Accompanying drawing 2 is the schematic diagram of bracing frame.

Accompanying drawing 3 is the schematic diagram of angle iron bracket.

In the drawings: 1, vertical rod 2, screw mandrel 3, balancing pole 4, balancing pole fastener 5, safety fastener 6, ropewinder 7, lifting wire rope 8, load-bearing fastener 9, angle iron bracket 10, scaffold floor cross bar 11, scaffold floor 12, bracing frame 13, support fastener 14, pressure pin 15, handle 16, insurance chain 17, cross backing plate 18, hinge 19, support bar 20, hook reinforcement bar 21, notch board 22, fixing hole 23, chain cylindrical void

As shown in Figure 1: the bottom of vertical rod 1 connects bracing frame 12, vertical rod is established, supporting fastener 13 is fastened on bracing frame in the vertical rod, upper end between per two vertical rods is connected by balancing pole 3, balancing pole fastener 4 with the balancing pole fastening in vertical rod upper end, lower end between two vertical rods is connected by pressure pin 14, the pressure pin two ends are angle iron bracket 9, by the lower end of load-bearing fastener 8 fastenings in vertical rod, traverse scaffold floor cross bar 10 on the angle iron bracket, and scaffold floor 11 is placed on the scaffold floor cross bar, and lifting wire rope 7 is tiltedly held the two ends of scaffold floor cross bar, ropewinder 6 is fixed on the balancing pole, shake ropewinder and the scaffold floor oscilaltion can be connected with a rhizoid bar 2 between pressure pin and the balancing pole, there is a handle 15 upper end of screw mandrel, turning handle can be with the scaffold floor oscilaltion, two insurance chains 16 are arranged between safety fastener 5 and angle iron bracket, and when scaffold floor was elevated to suitable position, available angle iron bracket was held, to insure chain and fix, can on scaffold floor, keep the safety in production.

As shown in Figure 2: bracing frame of the present utility model is folding cross backing plate 17, and vertical rod is fixed on the backing plate center, and backing plate is collapsible, the end points of backing plate is by hinge 18, connect support bar 19, support bar sets up supported fastener fastening in vertical rod, plays the effect of fixedly vertical rod.

As shown in Figure 3, angle iron bracket of the present utility model, some hook reinforcement bars 20 of inboard welding, guarantee that the scaffold floor cross bar can not slide, notch board 21 of edge welding of angle iron bracket, the load-bearing fastener fastens notch board, and there is a fixing hole 22 centre of angle iron bracket, two ends are chain cylindrical void 23, connect the insurance chain.
