Description

Locking member for wood (or bamboo) scaffold

The utility model is a kind ofly to build tying up fastening assembly and using this assembly to tie up fastening new method of load-bearing bamboo timbering, particularly bamboo timber scaffolding in the mode of tying up.

At present, the binding method of bamboo timber scaffolding is to tie up with galvanized wire (be the zinc plated mild carbon steel silk, down with) at the bamboo of all directions wood infall, and turns round its end section of sth. made by twisting and make it fastening.This method has shortcoming: turn round the sth. made by twisting degree little do not reach fastening effect, scaffold is dangerous, has turned round to have twisted with the fingers many usually to surpass the fatigue limit of galvanized wire and rupture, or hinder and to split, it is very easily out in the cold to hinder the person of splitting, and hinders later on to split the place because of stressed when developing into fracture, accident takes place suddenly, is taken by surprise.Moreover, when above-mentioned scaffold is removed,, can not use again because of galvanized wire is out of shape, have to cut off and be used as refuse and throw away, thousands of scaffold is all thrown away a large amount of, only uses galvanized wire once, and this long-term regular waste is a problem really.

The utility model purpose provides a kind of new-type fastening assembly of bamboo timber scaffolding and ties up fastening method with this assembly, solves the waste problem of aforementioned scaffold safety problem and Strapping Material in the lump.

The purpose of this utility model is achieved in that the button (method for making describes in detail in an embodiment) of making plurality of fixed of existing small size single-strand rope two ends section, and each globule is at a distance of a bit of distance, and the wire rope stage casing does not have globule.In addition make the mullion folder with steel band, it is identical by two, and the stage casing is made up of the intermediate plate and the bolt of long stem of recessed curved wall, or is made up of shape of a hoof cartridge clip and bolt of long stem that a steel band curves.On the paired dististyle of mullion folder all just like next group hole: it is close that bolt hole and two wear the pearl circular hole, and two U-shaped holes communicate with wearing the hole of bead respectively, cross one piece of bolt of long stem in the bolt hole, and its head and nut add packing ring and cover a part of wearing the hole of bead.It is bigger than the globule diameter on the wire rope to wear aperture, the hole of bead, and aperture, U-shaped hole is littler and bigger slightly than wirerope diameter than globule diameter.The knuckle in U-shaped hole is smooth round rib.Mullion presss from both sides on the recessed curved wall flat hole, but the inlay card internal gasket.

Assembly of the present utility model is in use: the mullion folder is loaded onto at the position that needs on mullion, and its paired dististyle transitory phase is apart from the distance of whole piece of bolt length, if meet thin mullion, but (it does not need the inlay card internal gasket everywhere.Only do standby), bolt and nut wouldn't be tightened, and exposes and wears the hole of bead.Tie up at crossbeam bamboo wood infall with wire rope, with instruments such as the pliers tense wire rope of trying one's best, remaining end section must have globule, with end respectively from the mullion both sides around to mullion folder end, each end is passed the hole of bead respectively, and the tension end tightly is stuck on the U-shaped hole, like this certain globule, each end of wire rope promptly is fixed, and has tentatively strained wire rope.Final step is the nut of bolt that screws up with a wrench, and occurs two effects simultaneously: the mullion folder had both clamped mullion, had further strained wire rope again, and the bamboo wood of all directions tightens together.When removing scaffold, unscrew nut, a complete set of assembly all can take off in good condition, and use next time again.

Because the intensity of wire rope is better than galvanized wire several fold, the mullion folder is again that steel band is made, and ties up so the safety of a complete set of assembly outclass galvanized wire.Because steel wire end section is not taked the distortion knotting, the use indeformable damage in back can be used repeatedly again, after service time is very long, if serious corrosion takes place, just can lose use value, notes protecting and can use the longer time; And galvanized wire can only be with once, and material still is that gloss still exists and but have to discard.The opinion utilization rate, the former is than hundred times of the high one-tenth of the latter, the opinion cost, the wire rope of same length is more expensive than galvanized wire, (but the length that galvanized wire needs is 2～3 times of wire rope), other has steel band sheet, bolt etc., see once that by using the cost of assembly will be higher than galvanized wire, but calculate by utilization rate, professional building unit expends cost in this respect, with assembly only for galvanized wire 1/tens in addition still less.Comprehensive safety and nothing waste various aspects, the utility model advantage is clearly.
