The cantilever girder 1 can adopt I-steel to ensure that the overall strength meets the requirements. Two girder 1 parallel arrangement of encorbelmenting, the interval is provided with a plurality of secondary roof beams 2 of encorbelmenting between the two. The secondary cantilever beam 2 can be made of I-shaped steel or square steel pipe and the like, and two ends of the secondary cantilever beam 2 are welded on the webs on the inner sides of the two main cantilever beams 1. A flat plate needs to be laid on the bottom frame platform, so that constructors can stand conveniently and materials can be stacked conveniently.
The bottom frame platform can be divided into an overhanging section and a fixed section according to functions along the direction of the overhanging main beam 1, and a blocking leg 3 protruding out of the bottom surface of the frame is fixed below the junction positions of the two areas. The protective enclosure 10 is arranged above the overhanging section of the bottom frame platform, and the rear support frame 6 is arranged above the fixed section of the bottom frame platform. It should be noted, however, that these two areas are functionally divided and still connected together in space, without clear limits, wherein the installation area in which the protective enclosure 10 is located is mainly cantilevered outside the building for unloading, while the installation area in which the back-up frame 6 is located extends inside the building, mainly for temporarily fixing the entire platform. Keep off leg 3 and can adopt the angle steel to realize, angle steel beading is in the bottom of one of them secondary beam 2 of encorbelmenting, and its effect is at the in-process of whole platform hoist and mount, and the degree of depth that stretches into the building to bottom frame platform through the card in the outside of building slab or roof beam limits.
In this embodiment, since there are no pre-embedded anchor and no hanging ring, the whole frame is fixed mainly by the adjustable top support 7 arranged at the top of the rear support frame 6. Referring to fig. 3, the back support frame 6 is formed by welding square steel tubes, and four vertical rods are respectively arranged at four corner positions. Four angular point positions at the top of the rear support frame 6 are respectively provided with 1 adjustable jacking 7. Each adjustable jacking 7 comprises a bolt and a bolt clamping piece, and the top of the bolt is planar and is used for being in contact with a floor on the top. The bolt clamping piece is a flat plate with an internal screw hole, the bolt clamping piece is welded and fixed with the vertical rod of the back-support frame 6, and the position of the screw hole of the bolt clamping piece is matched with the inner cavity of the vertical rod. The bolt clamping piece is arranged at the top of the vertical rod of the back support frame 6, and the bolt is screwed into the bolt clamping piece and then extends into the inner cavity of the vertical rod to form a screw pair for adjusting the plane height of the top of the bolt.
In addition, the unloading platform is hoisted through a crane, so that a hoisting point 5 for transportation and hoisting is arranged on the cantilever section of the bottom frame platform, and the hoisting point 5 can be a steel ring and is ensured to have enough strength. Simultaneously, in order to guarantee the stability of encorbelmenting, the stretch-draw has one or more pull rod 8 between the section of encorbelmenting of back brace frame 6 and bottom frame platform, stretch-draw one pull rod 8 on two girder 1 of encorbelmenting respectively in this embodiment. The pull rod 8 can be made of two round steels which are connected through a turn buckle 9, and the lug plates 4 are welded at two ends of the pull rod 8. Corresponding lug plate connecting pieces are also arranged on the vertical rods of the cantilever main beam 1 and the rear support frame 6, and the lug plates 4 at the two ends of the pull rod 8 are respectively connected with the vertical rods of the cantilever main beam 1 and the rear support frame 6 through inserted bolts. By adopting the pull rod mode, the length of the overhanging section can be further lengthened, and the length of the anchoring section can be shortened, so that the platform can be applied to various working conditions. In addition, in order to balance the tension of the cantilever section pull rod 8, a counter-pull rod can be arranged inside the rear support frame 6.
In this embodiment, the protection enclosure 10 includes rail and breast board, and the rail welds on girder 1 encorbelments, and the breast board is laid on the rail. The two overhanging main beams 1 are respectively provided with a protective enclosure 10.
