Reference numeral: screw rod 1, preformed hole 2, backing plate 3, nut 4, screw mandrel 5, shaped steel 6, floor 7.
The specific embodiment
When floor 7 decks are constructed, do preformed hole 2 at the pre-buried pvc pipe of anchor point, when overhanging type steel 6 is in place, U-shaped fastener screw 1 two ends screw mandrel 5 is passed preformed hole 2, U-shaped fastener screw 1 pass floor 7 decks at the bottom of plate, wear add backing plate 3 after two outer end screw mandrels, 5 band double nuts 4 fastening, overhanging type steel 6 firmly is cemented on floor 7 decks.
The present invention is simple to operate, detachably reuses, and satisfying under the prerequisite of using function, more can save cost, accelerating construction progress.
Screw rod 1 is U-shaped, two ends screw mandrel 5 mantle fibers.
Component of the present invention consist of: pre-buried pvc pipe is as preformed hole 2, and prefabricated screw rod 1 is U-shaped fastener, preparation backing plate 3, nut 4.
Insert U-shaped fastener screw 1 in the preformed hole 2, U-shaped fastener screw 1 front end screw mandrel 5 cover upper padding plates 3,3 times bands of backing plate upper cap nut 4.
Preformed hole 2 is pre-buried by pvc pipe.U-shaped fastener 2 both ends screw mandrels 5 mantle fibers are made.
Making of the present invention and fixing operation step are as follows:
(1) according to scaffold deadweight and working load, No. 6, calculative determination pedestal overhanging type steel type and inside protrudent length, and then model, quantity and the position of U-shaped fastener screw 1 are determined in checking computations, according to model, quantity, the position of fixed U-shaped fastener screw 1, pre-buried PVC is as preformed hole 2 when floor 7 deck concretes are built;
(2) screw rod 1U type fastener: determine screw rod 1U type fastener size according to outer outrigger shaped steel 6 specifications of suspension; prefabricated in advance; prefabricated screw rod 1U type fastener; 5 head brushes of screw mandrel oil guard; screw rod is done antirust processing outward, is convenient to dismounting and recycles, after floor 7 deck construction intensities reach requirement; by relevant position placed base shaped steel 6, penetrate screw rod 1U type fastener from the deck and block shaped steel 6.
(3) be inserted in continuous plate 3 under floor 7 decks, backing plate 3 bolt aperture center distance threaded 1U type fastener perforate center to center distance are consistent, and the aperture is slightly larger than screw mandrel 5 dowel diameter 2mm.
(4) it is fixing respectively to be screwed into double nut 4 for 3 times at 5 hook plates of screw rod 1U type fastener two screw mandrels, and 1-2 screw thread revealed in screw mandrel 5 outer ends, and two threads nut 4 fastening forces are consistent, and nut 4 should be consistent with screw rod 1U type fastener crab-bolt mantle fiber.
Patent of the present invention is applicable to all kinds of buildings and relates to the fixing of overhanging scaffold pedestal Cantilever Beams, set up especially fixing very convenient for high-rise, Super High overhanging scaffold, overcome unstable, unsafe factor that former traditional construction technology is come pedestal bearing shaped steel fixed band, satisfying under the prerequisite of using functional requirement, reach energy-saving and cost-reducing effect, simplified constructing operation, fastener can also carry out the series typing and produce, so existing stronger applicability of the present invention, economy is arranged again, be one and possess new product, the new technology that stronger utilization and extention is worth.
The present invention adopts fixedly overhanging base frame shaped steel of U-shaped fastener, and is stressed clear and definite, can make things convenient for calculative determination to go out pedestal overhanging type steel model according to upper load, thereby calculate model and the quantity of U-shaped fastener; U-shaped fastener can batch production production, can determine U-shaped fastener model and specification according to the difference of pedestal cantilever span, the variation of upper load, become series as the standard element batch production, produce economic benefit; Adopt this method construction, be subjected to the work progress influence factor few, construction quality is guaranteed, and is safe; Adopt this method simple and efficient to handle, U-shaped fastener and matched mat plate can reuse, and have greatly saved labor and materials, have saved cost, have accelerated construction speed; This method applicability is strong, is applicable to relate in all kinds of building operations the fixing of overhanging scaffold pedestal shaped steel.
