Abstract

The utility model relates to a combined spiral stair, which comprises a handrail, a stair column, a pedal and middle shaft assemblies. One end of the pedal is sheathed with a middle shaft, and the other end is inserted with the bottom of the stair column. The upper end of the stair column and the bottom of the handrail are connected by screws, and handrail assemblies are connected by screws. The middle shaft assemblies are connected by inner and outer screw threads. The utility model has the advantages that metal connecting pieces which are easy to assemble and disassemble are used between the assemblies, and the connection method of rivet welding or gluing is replaced; thus the work efficiency of installation is enhanced, and multiple disassembly, assembly and repeated use of the stair can be achieved.

Description

The combined type spiral stairs

The utility model relates to a kind of helical structure stair, particularly combined type spiral stairs.

Along with realty industry is flourish, duplex building or title spring layer building arise at the historic moment, and corresponding indoor staircase has just become necessity practical and that decorate.The structure of indoor staircase, form have many kinds, and wherein the stair of helical structure more often are used.Popular spiral indoor staircase generally is the pedal that axis, iron plate outsourcing solid wood are made with the steel pipe, the pedal of its stair and middle between centers be connected with cleat stanchion between to be connected all be to adopt welding manner, and between each section handrail also be with gluing connect continuous.There is following shortcoming in the stair of this prior art: 1, mounting process complexity, time-consuming taking a lot of work; 2, after assembling is used, can't intactly dismantle, assemble again and use; 3, cost is higher.

The utility model purpose is: overcome the deficiency of prior art, the combined type spiral stairs that provide a kind of and can assemble quickly and easily or dismantle, repeatable dismounting is used.

Technology difference maximum between the utility model and the prior art is: to not being to connect by rivet welding or wooden adhesive means between the assembly of forming spiral stairs, but utilized the metal coupling member that can adorn easily and unload.

The utility model structural concept: the combined type spiral stairs, comprise armrest assembly, cleat stanchion assembly, pedal assembly and Middle shaft assembly, it is characterized in that:

(1) open on pedal assembly one termination on the Middle shaft assembly that an annular distance is socketed in corresponding joint number, another termination is plugged in the groove that corresponding cleat stanchion bottom has,

(2) armrest assembly end to end, between connect and series connection constitutes whole handrail with screw,

(3) unsettled, the upper end in cleat stanchion lower end is connected with corresponding armrest assembly bottom with screw by connector.

On above-mentioned basic scheme basis, can design: pedal assembly is one to be the trapezoidal shape plate, in the groove that the cleat stanchion bottom that the open loop borehole jack is connected on the axis on its narrow termination, both sides, wide termination are plugged on two adjacent arrangements respectively has; One end of every joint Middle shaft assembly is that tube connector, an other end that has internal thread is to have the male union that is complementary, and all is equipped with one and presses solidly ring on the upper and lower end face of pedal assembly of upper and lower two joint Middle shaft assembly sockets.

In addition, the head of armrest assembly or tail end bottom has the groove of the loading and unloading nut that can hold the screw afterbody.

The utility model advantage is:

Owing to assemble the each several part assembly by means of the metal coupling member, whole spiral stairs is easy to loading and unloading.Make on the one hand that installation work is simple and direct have been changed, a cover stair assembled on site only needs outer non-industry personnel to take 10 hours to get final product; Can repeat to utilize again after the dismounting on the other hand, can remove former stair when promptly in a single day the user removes new house and re-assembly again to the new home and use.

Fig. 1 is the utility model package assembly schematic diagram.

Fig. 2 is an A portion amplification view among Fig. 1.

Fig. 3 is a B portion amplification view among Fig. 1.

Fig. 4 is a C portion amplification view among Fig. 1.

Fig. 5 is that assembling drawing amplifies in D portion among Fig. 1.

Below in conjunction with drawings and Examples the utility model is done further narration:

As shown in Figure 1, the utility model is combined mutually by axis 1, handrail 2, cleat stanchion 3, pedal 4 four major parts.As the cocke-stair structure, it is the center with vertical axis 1, handrail 2 rises in the shape of a spiral around shape, and an end of all pedal 4 assemblies all socket-connects with the axis 1 joint assembly of corresponding height, the other end then plugs cleat stanchion 3 upper ends and handrail 2 bottom connections with two adjacent cleat stanchion 3 bottoms.In the utility model, axis, handrail, cleat stanchion, pedal all are to be made up of the identical assembly of several construction standards of oneself respectively, and the standardization of assembly can conveniently be produced, also ease of assembly.

Fig. 2 shows is structural relation between the armrest assembly.Handrail 2 is in series from beginning to end by a plurality of handrail 2 assemblies among Fig. 1, one head bottom part of each handrail 2 assembly has groove and string nail hole, when assembling, after the head and the tail end face of two handrail 2 assemblies offseted, promptly insert screw 5 earlier from groove, and then on screw 5 afterbodys, be equipped with top nut 6, tighten, such two inter-modules have just closely been combined as a whole.And the like, all handrail 2 inter-modules all are to connect like this.

Fig. 3 has showed the connecting relation of handrail 2 with cleat stanchion 3 inter-modules.The top of every cleat stanchion 3 assemblies all uses screw 8 that a hardware 7 is housed, and these member 7 end faces contact with the bottom surface of handrail 2, by screw 8 the two is fixed as one then.

Fig. 4 has showed connecting relation between pedal 4 and the cleat stanchion 3.The bottom of cleat stanchion 3 has the termination that groove holds pedal 4 and inserts, and with screw 9 the two is combined as a whole then.

Fig. 5 showed axis 1 respectively save assembly be coupled to each other the relation and pedal 4 assemblies and axis 1 between connecting relation.As shown in the figure, the upper end of every joint axis 1 assembly be have externally threaded tube connector 10, lower end is the tube connector 11 that has internal thread, whole axis 1 is if assembly is upper and lower is in series for a joint, and adjacent two assemblies are exactly that inner, male-pipe connects when linking.And having that end of annular distance, pedal 4 just is socketed on internal thread tube connector 11 outer walls of axis 1.Pressing solidly ring 12 as for upper and lower two, is to be used for saving the pedal 4 that will be enclosed between the two when axis 1 assembly screw thread screws and compressing, reinforce when upper and lower two.
