Description

But a kind of assembling combined staircase

Technical field: the utility model relates to a kind of people can arrive the stair that the free again assembly of existing field boundary constitutes, and belongs to the building unit field.

Background technology: stair are building members in the building, the stair that conventional stair have Wooden stair, steel stair and pour into a mould with reinforced concrete.These stair all need on-the-spot work of building further to construct during fabrication, and its construction area area is big, long construction period, and the profile heaviness, after stair completed, stair integral body can not arbitrarily move resettlement.Chinese patent CN00252985 discloses a kind of assembly type stair, it is to be interconnected by two row zigzag supports, its top and bottom are fixedlyed connected the assembly type stair of formation respectively with building, the shortcoming of this stair is profile dullnesses, moulding is stiff, and is complex-shaped, the construction trouble, there is not special transverse connection between every stair, whole stressed bad.

Summary of the invention: the purpose of this utility model is overcoming the shortcoming of prior art, and inventing a kind of people can be at the existing free assembly of field boundary, stressed more reasonable, the stair that outward appearance is better, rational in infrastructure.

Structure of the present utility model is: but a kind of assembling combined staircase, it comprises broadstep, other plate, balustrade, handrail pole, column and cramp bar are formed, plate is made up of the several piece junction plate by it is characterized in that, the both sides of every broadstep have identical up and down junction plate to intersect folded mutually with the junction plate of upper and lower floor ladder pedal homonymy respectively, junction plate is L-shaped, and have several fixing holes, between broadstep and cramp bar, cushion block is housed, with bolt, screw each parts is interconnected, constitute stairway unit; There is screw at the cushion block two ends, and the outside end of cushion block has boss, and the boss end inserts in the broadstep shrinkage pool, and the cushion block other end is placed on the cramp bar, and last attachment screw is connected broadstep with cushion block, and following attachment screw is connected to one with cushion block and cramp bar; Bolt passes the fixing hole in two folded mutually junction plates of intersection, is screwed in the screw of cramp bar end, and the junction plate of cramp bar and the left and right sides is combined as a whole, and bolt passes the fixing hole in two junction plates that intersection folds mutually, uses nut screwing clamping; The oblate column cap of bolt side has aperture; Nut is stamped trim, and trim is stamped in last attachment screw termination.

Operating principle of the present utility model is: every stair are made up of several stairway unit, each stairway unit is flight (step).Every other plate (10), the cramp bar (6) of stair by the left and right sides, the broadstep (1) and the balustrade (3) that are positioned on the cramp bar constitute.When the making stair were the linear pattern stair, broadstep (1) was identical rectangle, and the junction plate of both sides (2) is a flat shape and identical.When the making stair were the screw type stair, broadstep (1) was a fan shape, and promptly broadstep (1) outside is an orthodrome, the inboard is little circular arc, the junction plate of both sides (2) is circular-arc, and outer side connecting plate (2) is an orthodrome, and interior side connecting plate (2) is little circular arc.

Other plate (10) is formed (shown in Fig. 2,3) by several piece junction plate (2), monolithic junction plate (2) is L-shaped, every junction plate (2) intersects folded mutually with the junction plate (2) of the upper and lower broadstep (1) homonymy respectively, with several bolts (21) they are fixed, repeat above-mentioned connected mode, promptly form the other plate (10) of monoblock.Cramp bar (6) is placed between symmetrical two side connecting plates (2), bolt (22) passes the fixing hole (5) in folded mutually two junction plates (2) of intersection, be screwed in cramp bar (6) the end screw (61), bolt (21) passes the fixing hole (5) in folded mutually two junction plates (2) of intersection, tighten with nut (9), constitute a complete stairway unit.

Between cramp bar (6) and broadstep (1), cushion block (7) is housed, cushion block (7) boss (72) end inserts in broadstep (1) shrinkage pool (11), cushion block (7) other end is placed on the cramp bar (6), last attachment screw (73) is connected broadstep (1) with cushion block (7), following attachment screw (74) is connected to one with cushion block (7) and cramp bar (6).

For making the stair monnolithic case more attractive in appearance, the bolt (21,22) that this device uses is oblate column cap, and its side has aperture (211,221).When tightening, in the aperture (211,221) with instrument inserting bolt head, can twist bolt, reduce the stiff sense of common hex bolts.

Broadstep in this device (1) can adopt wood materials, metal material and glass material to make.

The utlity model has the structure design novelty, the good looking appearance exquisiteness, the loading and unloading combined and instant, construction is quick, but is a kind of new assembling combined staircase that is suitable for being suitable for.

Description of drawings: below in conjunction with the accompanying drawing illustrated embodiment, the present utility model structure is described further, but protection domain is not limited thereto embodiment.
