Description
Technical field
The present invention relates to the scaffold of the high verticality of band safety climbing ladder, also relate to the manufacture craft of the vertical rod of the scaffold of the high verticality building this band safety climbing ladder.
Background technology
In prior art, the scaffold built with steel pipe, is generally made up of cross bar and vertical rod, to cooperatively interact the special steel pipe scaffold of the construction cat ladder passage that carries out building by means of latch and latch receiving system.The special steel pipe scaffold of this construction cat ladder passage is built and convenient disassembly, both be convenient to assembling and be also convenient to storage and transport, but because the height of the special steel pipe scaffold of construction cat ladder passage increases along short transverse longitudinal stack by vertical rod, vertical rod is made up of main pipe body, nested end, the part of nested end to pack in main pipe body one end and is welded and fixed and is integrated, when building, the other end of main pipe body socket-connects with the nested end of adjacent vertical rod and fixes with latch, thus achieves vertical rod along short transverse longitudinal stack.During owing to making vertical rod, the internal diameter of main pipe body needs the external diameter being greater than nested end just can be nested and weld, namely both sizes are needed to be larger matched in clearance, but larger matched in clearance often causes the concentricity after both welding poor, make the verticality of the scaffold of superposition can not get ensureing, have impact on use safety.In addition, the cat ladder of scaffold self only possesses the function of ascending a height, and does not possess and reinforces self firm ability, and its security needs ensure by ladder and the affixed of scaffold.
Summary of the invention
Inventing first technical problem to be solved is provide the scaffold of the high verticality of the band safety climbing ladder that a kind of vertical rod concentricity is high, invents second technical problem to be solved to be, the manufacture craft of the vertical rod providing concentricity high.
The present invention solves the technical scheme that first technical problem adopt: a kind of scaffold of the high verticality with safety climbing ladder comprises scaffold, this scaffold cross section is rectangular, comprise vertical rod, this vertical rod comprises main pipe body, nested end, the part of this nested end to pack in this main pipe body one end and is welded and fixed and is integrated, vertical rod is by four right angle electrical distributions of this rectangle, the main pipe body of vertical rod socket-connects with the nested end of adjacent vertical rod and fixes with latch, forms four row vertical rod posts respectively in these four right angle electrical vertical rods along short transverse longitudinal stack; Chrysanthemum shape latch dish, this chrysanthemum shape latch dish is fixed in respectively on vertical rod post at sustained height and forms chrysanthemum shape latch disc layer, and chrysanthemum shape latch disc layer is distributed with M layer along short transverse, M >=2; Cross bar, every layer of chrysanthemum shape latch disc layer is provided with this cross bar, the chrysanthemum shape latch dish Joint on cross bar two ends and adjacent two vertical rod posts; Cat ladder, this cat ladder is placed in this rectangle, is tiltedly set up between different chrysanthemum shape latch disc layer, cat ladder has P, P >=2, the ladder mutual dislocation of adjacent cat ladder and establishing in opposite directions, the cat ladder of being separated by is mutually stacked, cat ladder continues from below to up successively, and there is ladder cat ladder both sides, and N block stepboard to be distributed between two ladders and to be fixed on ladder, N >=1, cat ladder two ends have a platform respectively, make cat ladder be Z-shaped, and each cat ladder has a ladder rail respectively, this ladder rail has support bar and bar, and ladder rail is placed on the ladder of rectangle middle part; There is caliber contractile ring main pipe body one end, and the internal diameter of this caliber contractile ring is suitable with the external diameter of nested end, also comprises the sealing weld through hole be located on caliber contractile ring.
Beneficial effect: in technique scheme, because there is caliber contractile ring main pipe body one end, the internal diameter of this caliber contractile ring is suitable with the external diameter of nested end, caliber contractile ring is combined closely with nested end, main pipe body is greatly improved with the concentricity of nested end, and concentric main pipe body is located with nested end by sealing weld through hole mutually that be located on caliber contractile ring, be convenient to main pipe body connect with nested end loops boxing before location, ensure concentricity.The scaffold verticality that the vertical rod using this main pipe body and nested end to form is built is guaranteed, thus improves the safety of scaffold.
As the further improvement to technique scheme, the lower end of bar and the upper end Joint of support bar, the lower end of support bar is removably fixed on the ladder of self, the adjacent cat ladder of upper level is pointed in the upper end edge ladder direction of bar, and is fixed in the same point of the adjacent ladder of upper level together with the lower end of the support bar adjacent with upper level.This improvement ladder rail plays the effect of being reinforced by adjacent ladder up and down, cat ladder self is only possessed and reinforces self firm ability, and its safety is more secure.
As the further improvement to technique scheme, support bar and bar are bent one-body molded by steel pipe.This improvement makes ladder rail more firm.
As another concrete scheme to technique scheme, ladder cross section is the rectangle of 75x25x2mm, and described stepboard is the flat board of 500x305x1.5mm.This concrete scheme facts have proved, is more rational size dimension in scaffold execute-in-place.
The present invention solves the technical scheme that second technical problem adopt: a kind of manufacture craft of vertical rod, first six lobes one end of main pipe body being pierced into hydraulic press close up mould, a part for nested end is packed into one end of main pipe body, primer fluid press, main pipe body one end is closed up mould extruding by six lobes and forms caliber contractile ring, and the internal diameter of this caliber contractile ring is suitable with the external diameter of nested end; Then on caliber contractile ring, sealing weld through hole is bored.
Beneficial effect: in technique scheme, owing to a part for nested end to be packed into one end of main pipe body, namely the effect of core is played in nested end, six lobes close up mould and belong to the mould that hydraulic press this city carries, this technical scheme mold arrangement is simple, easy to operate, centering is accurate, reaches the requirement of vertical rod axiality.
