Preferably, a plurality of two connecting rods are arranged between the adjacent main rods 1, two ends of each two connecting rod are connected with the corresponding main rod 1, the middle parts of the two connecting rods are connected in series through a reinforcing rod 10, and the anti-falling net is fixed on the two connecting rods and the reinforcing rod 10.

As shown in fig. 3, 4 and 9, the two connecting rods, the reinforcing rod 10 and the main rod 1 can be directly connected to the ground, and then the connected structure can be hoisted to the cross rod 4. These two connecting rods include two connecting rods 8, the both ends of this connecting rod 8 all are fixed with the buckle, the cover is equipped with the support 9 that slides on this stiffener 10, this support 9 that slides is the sleeve 5 shape, be fixed with two first rings 15 on the periphery wall of support 9 that slides, two these first rings 15 supply the buckle of one of them one end of adjacent connecting rod 8 to connect, be fixed with a plurality of second rings 12 on the both sides wall of mobile jib 1, this second ring 12 supplies the buckle of the other end of adjacent connecting rod 8 to connect, the inside of support 9 that slides is worn to locate by stiffener 10. The two connecting rods and the reinforcing rod 10 provide support for the adjacent main rods 1 and support for the anti-falling net.

Preferably, the fall arrest net is secured to the two links and the reinforcement bar 10.

The arrangement of the two connecting rods and the reinforcing rod 10 ensures that the anti-falling net has certain support, and is not easy to damage when a larger object falls down.

As shown in fig. 1, fig. 2, fig. 4 and fig. 5, the invention also provides a method for installing the push-pull type section steel cantilever protection platform, which comprises the following steps:

providing the push-pull type section steel cantilever protection platform;

sleeving a plurality of main rods 1 on a cross rod 4 of a scaffold 3 through the lantern ring 7, adjusting the distance between the plurality of main rods 1, and fixing the positions of the plurality of main rods 1;

the main rod 1 is rotated around the cross rod 4 to the direction far away from the scaffold 3 through the support rod 2 until the angle to be fixed is reached;

fixing the support rod 2 and the scaffold 3;

when the protection platform needs to be folded, the support rod 2 and the scaffold 3 are removed from the protection platform, and the main rod 1 is rotated around the cross rod 4 until the main rod is attached to the outer vertical surface of the scaffold 3.

When the bracing piece 2 was located horizontal pole 4 tops, when bracing piece 2 chooseed for use steel pipe or wire rope, after mobile jib 1 connected on horizontal pole 4, pulling bracing piece 2 made mobile jib 1 rotatory around horizontal pole 4, adjusted suitable angle, fixed bracing piece 2 and scaffold frame 3 again. When meeting the extreme weather of strong wind or heavy rain, can directly demolish the fixed of bracing piece 2 and scaffold frame 3, withdraw mobile jib 1 to the scaffold frame 3 of hugging closely to reduce the damage to the protection platform and avoided the former production of secondary danger, be particularly useful for high-rise building or suburb, coastal etc. area that the wind load is great.

Preferably, a plurality of groups of two connecting rods are arranged between the adjacent main rods 1, two ends of each group of two connecting rods are movably connected with the corresponding main rods 1, and the middle parts of the two connecting rods between the adjacent main rods 1 are connected in series through a reinforcing rod;

before the main rods 1 are sleeved on the cross rod 4 of the scaffold through the lantern ring 7, the main rods 1 are mutually closed, and two connecting rods between the adjacent main rods 1 are in a folding state;

this plug-type shaped steel of integral hoisting protection platform to the pending mounted position of scaffold frame of encorbelmenting, locate this horizontal pole 4 with many these mobile jib 1 through this lantern ring 7 cover.

Put mobile jib 1 on job site ground, can assemble as a setting plate with three or four mobile jib 1 according to the demand, to slide support 9 and take connecting rod 8 to install on the second ring 12 of 1 lateral wall of mobile jib, and tighten up into "W" form with mobile jib 1 in the single protection platform, rethread tower crane hangs to the floor that needs the protection, penetrate the lantern ring 7 of mobile jib 1 from the one end of horizontal pole 4, take off the closed accessory of 7 breach departments of lantern ring, remove mobile jib 1, 7 breachs of the lantern ring through mobile jib 1 pass the tie point of horizontal pole 4 with scaffold frame 3, thereby remove mobile jib 1 and expand to the assigned position, can adopt the fastener to fix the position after the expansion.

Preferably, after this protection platform is encorbelmented to plug-type shaped steel uses and accomplishes, cancel the fixed to the position of this mobile jib 1, tighten up many this mobile jib 1 along 4 length direction of this horizontal pole, demolish the fixed of bracing piece 2 and this scaffold frame 3, take apart cup joint of this lantern ring 7 and this horizontal pole 4, hang this mobile jib 1 again and move.

When this protection platform demolishs, but the structure that tightens up is favorable to demolising fast and hoist and mount convenience, because the structure is for dismantling the connection, consequently need not cause the damage to protection platform, can wholly demolish, has enough to meet the need to other job sites and uses, has improved the utilization ratio.

According to the invention, the main rod is rotatably connected with the scaffold, and the support rod is also rotatably connected with the main rod, so that the protection platform can be closely attached to the scaffold at any time, and the technical problem that the cantilever protection platform in the prior art is easily damaged and falls in extreme weather is solved. This protection platform lets protection canopy of encorbelmenting under the condition of not demolising, can be like building "austral window, sliding sash", realize the expansion of "windowing" and "closing the window" in the outer frame outside, hug closely the effect, effectively reduced extreme weather such as strong wind, heavy rain, strong typhoon under the protection canopy of encorbelmenting damaged, the risk that blows off, avoided the production of secondary hazard, to high-rise or super high-rise building in wind load great area such as suburbs, coastal, have stronger practicality.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
