Abstract
The utility model discloses an assembled integral stair, particularly an assembled integral helical stair. All level steps of the utility model are totally formed by box-shaped bodies which are composed of step panels, front connecting plates, rear connecting plates, inner support plates, side support plates, and bottom panels; in addition, the rear connecting plate of the step at the next lower level is connected with the front connecting plate of the step at the next higher level by screw bolts to form the assembled integral stair and the rear connecting plate of the step at the uppermost level is connected with floors of buildings. The utility model cancels the works which need to be carried out, such as, moulding plates manufacture, steel bar syndesis, scaffolding construction and disassembly, maintenance, etc. when a traditional concrete stair is manufactured; in addition, because each step forms a box-shaped body structure, and the steps with the box-shaped body structures are connected with each other by the screw bolts or a welded method to form the assembled integral stair. The utility model has the advantages of simple structure, low cost, and short manufacturing construction period; furthermore, the industrialization large scale production is easily realized, the manufacture and the installation are totally convenient and easy, etc.
Description
Technical field:
The utility model relates to a kind of integrally assembling staircase, and particularly a kind of assembled integral spiral stairs belongs to the stair technical field.
Background technology:
At present, the employed spiral stairs of building mostly is the reinforced concrete cast-in-situ winding stairs in the prior art, and in indivedual maisonettes and multilayer villa, and also adopting has the encorbelment small-sized steel cocke-stair of steel ladder plate of steel column, or with the winding stair of shaped steel brake forming.Mainly there are the following problems for these stair of the prior art or cocke-stair:
1, the problem that mainly exists of large cast-in-situ steel reinforced concrete stair or cocke-stair is:
(1). construction molding is difficulty, and steel content is big, and this is a fact clear to all;
(2). dead load is big, causes increasing the physical dimension and the material usage of supporting construction;
(3). support manyly during construction, the template amount is big, and construction period is slow, the steel concrete spiral stairs of a floor height 4.5m diameter 4.2m, finishing not very, he from shuttering, support, wire-tie, form removal behind the in-situ casting concrete, maintenance, construction period reached more than 40 days.
(4). the cost height, it substantially exceeds conventional Vierendeel girder plated construction by norm;
(5). the weight of encorbelmenting is big, and is unfavorable to structural seismic;
2, the problem that mainly exists of small-sized steel cocke-stair is:
(1). in dwelling house, false cocke-stair often is set, promptly establishes the steel column winding stair at the winding stair center, gangboard one end is welded in steel post, and an end is encorbelmented, and architectural effect is poor, does not play the effect of spatially spiral ladder, for doing something against one's will;
(2). steel using amount is big, and cost is higher;
(3). real cocke-stair, curve helical form with shaped steel after, connect gangboard again because it is not a bend in one direction, but multidirectional helically bent, moulding is very difficult, the manufacturing cost height.
Because there are the problems referred to above in spiral stairs of the prior art, therefore in actual use, its result of use still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, cheap, fabrication and installation all to make things convenient for and be easy to integrally assembling staircase, particularly a kind of assembled integral spiral stairs is to overcome the deficiencies in the prior art.
The utility model is to constitute like this: the box-like body formation that its steps at different levels all are made up of to gripper shoe (5) and bottom panel (6) step panel (1), preceding radially junction plate (2), back junction plate (3), interior hoop gripper shoe (4), side ring, and the preceding hoop junction plate (2) of the back junction plate (3) of next stage step by bolt and the upper level step integrally assembling staircase that is formed by connecting, the back junction plate (3) of its upper level step is connected with the floor built-in fitting of building; Two outer rings parallel 1～5 interior hoop gripper shoe (4) that is provided with between gripper shoe (5) at every grade of step; The surface configuration of forming the step panel (1) of every grade of step is fan-shaped or rectangle, and its fan-shaped angle α is 5～20 degree; Forming the step panel (1) of every grade of step box physique structure, preceding junction plate (2), back junction plate (3), interior hoop gripper shoe (4), outer ring is connected or welds to gripper shoe (5) and bottom panel (6) screw that is connected to each other; The integrally assembling staircase of forming by step panel (1), preceding junction plate (2), back junction plate (3), interior gripper shoe (4), side gripper shoe (5) and bottom panel (6) that box-like body constituted be shaped as 90 ° of circular arcs, 180 °, 270 °, 360 ° of helical space steel ladders.
Owing to adopted technique scheme, integrally assembling staircase of the present utility model has following characteristics: it is assembled into one by one with several thin-plate element spares and marks time, and each unit of marking time connects by erection bolt, becomes the moulding ladder of every floor lid; After each connector of moulding ladder was welded to connect, the top board welded and installed of will marking time again promptly formed the cocke-stair of space-load.Adopt the utility model to make stair, owing to cancelled making template, the wiretie that must carry out when making the conventional concrete stair, built and dismantled work such as scaffold, maintenance, therefore the utility model not only can shorten the making duration greatly, but also has reduced cost of manufacture; In addition, because every grade of step of the present utility model is a box shape structure, and the method that welding is installed by bolt is connected to an integrally assembling staircase with the step of box shape structure, thereby stair of the present utility model also have, and materials are few, intensity is high, lightweight characteristics.Therefore, the utility model compared with prior art, the utlity model has simple in structure, cheap, make the duration short, realize that large-scale industrialization production and fabrication and installation all make things convenient for advantages such as easy easily.The utility model not only is suitable for making winding stairs that building uses, and is suitable for making employed spiral stairs in small-sized dwelling house, the villa.Because the floor height of spiral stairs is little in small-sized dwelling house, villa, diameter is little, load is little, manufacturing materials of the present utility model can change plank or plastics into by steel plate, and by connecting ironware and the bolt assembled integral compact spiral stair that are formed by connecting.It has tangible advantage than existing " small-sized steel spiral stairs ", and makes simple.
