Abstract

The utility model discloses an architectural scaffold, in particular to an iron scaffold. Prior steel tube scaffold has the disadvantages of high cost, large volume, large quantity required for the lumber, and poor operational condition for workers on racks. The utility model adopts the scaffold made from the angle steel and increases safe railings and safety fences. The purpose of the utility model is that the cost of the scaffold is reduced; the scaffold has simple structure and convenient carry over; each layer (step) of frames can be risen and fallen for adjusting the height. The scaffold improves the operational condition of workers and increases the safety control.

Description

Multipurpose safe scaffold with rise-fall regulation by angle steel

The utility model relates to a kind of building scaffold, particularly the steel scaffold.

The station post of existing steel scaffold, cross-arm are to be made by steel pipe, are all connected by the cast iron fastener between its station post, the cross-arm, and all whole timber of the scaffold floor on its scaffold or bamboo basketry are made.The problem that prior art exists is: steel pipe, cast iron fastener cost height, weight greatly, heavy.Therefore, install, carry and dismantle all inconvenient.Whole timber consumption is big, and is local narrow and small on the scaffold floor, inconvenient operation, and also accidents happened easily, it is reported, in the building operations death by accident, accounts for 40 nine percent from high falling, and as seen existing scaffold safety guarantee is still implemented inadequately.

The purpose of this utility model is to propose a kind of improved angle steel ascending/decending multipurpose safety scaffold at the deficiencies in the prior art.It can save material, puts in order timber, reduce cost, and improves operating condition, increases work efficiency.

The purpose of this utility model is to realize like this, the station post of scaffold, cross-arm are all made with the angle steel that two sides have some holes, on scaffold, increase with holes, the angle steel system in two sides, security guardrail, be by corresponding hole on the angle steel between its station post, cross-arm, the security guardrail, fixedly connected with screw, nut.Scaffold floor is that plank agllutination that the rectangular feet hand frame that is welded into by angle steel and wood chipboard are combined into closes and forms.Thereby the high and low position of pin hand frame on the post of station is adjustable.The plank piece that wood chipboard is combined into also can directly be tiled on the station post of cross-arm that angle steel makes and horizontal dress.In the lower end of bottom station post, "+" font backing plate is housed, be welded with little diagonal brace between the bottom of backing plate four ends and bottom station post.Available some cross-arms are dressed up ladder between two station posts of scaffold floor.The security guardrail that is used for adorning the cross-arm of ladder and scaffold can change and be two ends first steel band understudy steel with holes.Scaffold also has a first steel of usefulness and galvanized wire to make, and upper hook can hang on the security guardrail, and the sidepiece hook can hook the safety barrier of station post.

The utility model compared with prior art, angle steel is more cheap than steel pipe, and is light by 40 percent with the angle steel weight ratio steel pipe of intensity, do not need the cast iron fastener, thereby reduced the cost cost of scaffold, simplified the structure of scaffold, and the carrying, installation and removal all very convenient, saved steel again.Again need be with putting in order timber because of scaffold floor, only being combined into wooden unit with wood chipboard puts into pin hand frame, thereby saved whole timber, and also smooth on the scaffold floor, safety is reliable, every layer of (step) shelf again can lifting at any time on the post of station, make it be in optimum height, when the workman operates, just can not bend over, do not stand a tiptoe, thereby improved workman's operating condition, also improved operating efficiency.Again because of having added security guardrail and safety barrier, thereby also strengthened safety guarantee.In addition, station post, the cross-arm made owing to angle steel can arbitrary load become ladder, track, whole derrick, interior scaffold, so the utility model has multiple function again.
