Abstract

The utility model relates to assembled stairs using a structure as a characteristic. The utility model is characterized in that the assembled stairs is orderly connected by z-shaped brackets and is divided into two rows, and a plane pedal is fixedly arranged between each two corresponding z-shaped brackets in the two rows through fasteners. The utility model adopts a net frame type steel structure capable of being assembled and has the advantages of compact form, firmness and durability, beautiful appearance and wide application scope. The assembled stairs can be decomposed into elements which are produced in bulk in factories and then are conveyed to each user to be installed, and the assembled stairs has simple and convenient assembly, time saving and labor saving. When the assembled stairs is not used, the assembled stairs can be disassembled without generating any permanent building garbage and waste materials so as to be favorable to environmental protection.

Description

A kind of assembly type stair

The utility model relates to a kind of stair, and specifically a kind of is the design of the stair of feature with the structure.

Present architectural stair mostly is reinforced concrete structure, and in addition, small part is wooden or iron and steel welded structure form.The stair manufacture process of reinforced concrete structure is loaded down with trivial details, and form is single and moulding is simple, but also needs finishing, constructs also normal building waste and the refuse of producing in the process.Wooden and steel structure stair, complicate fabrication process, cost is higher, and in addition, Wooden stair is durable inadequately, and the moulding of steel welding stair is simple, lacks aesthetic feeling and artistry.Above-mentioned three kinds of stair all need constructing operation at the scene, manufacturing cycle is long, time-consuming, along with people to improving constantly of requiring of building level with to the personalization of storied building structure and the demand of multiple stratification, under robust prerequisite, people have proposed more and more higher requirement to the structure of stair, moulding, aesthetic feeling etc., and existing stair obviously can not satisfy these requirements.

The purpose of this utility model just provides a kind of batch production production, the assembly type stair of aggregate erection at the scene, to beautify moulding, conveniently to make and do not produce building waste or refuse.

The utility model is achieved in that these assembly type stair are joined successively by z type support and are divided into two row, in two row, be fixed with the plane pedal by connector between per two z type supports of correspondence, so just can form assembly type stair, the top z type support and the upper strata floor of stair are fixedly connected, the bottom z type bracket supports of stair also is fixed on the floor, can constitute simple in structure and robust assembly type stair.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2, Fig. 3 are two kinds of specific implementation figure of the present utility model.

As shown in Figure 1, the basic element of character of this assembly type stair is exactly z type support 1 and plane pedal 2.The lower transverse beam of a last z type support aligns with the top rail of next z type support, has the hole on the connecting portion 6 of correspondence, and bolt 3 passes connecting hole and spins fixing by nut 4.Between the support of two row parallel alignment, also be fixed with plane pedal 2, fix a pedal on each level, promptly be assembled into stair.The upper edge of stair is fixed on the upper strata floor 8, and the supporting of the base of stair also is fixed on lower floor's floor or the floor 9.

For safety, in the occasion of needs, this assembly type stair also should be equipped with guardrail, and this guardrail is made up of vertical rod and balustrade.Be fixedly connected with vertical rod 5 on z type support 1, the upper end of vertical rod 5 is connected to balustrade 7.Stair railing can be provided with on the both sides of stair, if stair one side by wall, also can be only in the arranged outside of stair.

Fig. 2 is the staircase structure figure that band stair railing and assembling are shaped.If stair are longer, for further increasing the firm degree of stair, can between stair middle part and floor 9, column 10 be set, the column upper end has transverse slat 12 to withstand on the bottom surface of two corresponding z type supports 1, so just can make stair more sturdy and durable.

For the stair that needs turn to, can realize that Fig. 3 is a kind of structure chart that turns to stair by setting up the big pedal of turning.Be provided with the big pedal 11 of turning at the stair middle part among the figure, this pedal and adjacent two groups of z type supports 1 up and down join respectively, there is supporting upright post 10 bottom surface of big pedal, and the top edge of big pedal is connected with vertical rod 5, and the balustrade 7 that vertical rod 5 upper ends connect joins with the balustrade of stair activity respectively.Geometry by the big pedal of conversion and with the limit that is connected and fixed of big pedal, the steering angle of stair is set, to satisfy people to building personalization and multiple demands according to building construction layout or house owner's hobby.

In above-mentioned various stair, also can be on the vertical plane between two z type supports 1 arranged side by side fixing backplate, promptly the neutral gear between the two-stage step is blocked by backplate, the safety of using with further raising stair.

Z type support and plane pedal can be made into the form of structure that has various different shapings, decorative pattern or pattern, and can spray into different colors, make stair create an aesthetic feeling and artistry, to satisfy the different demand of people.

The utility model adopts assemblnig netted steel structure, and form is simple and direct, and is sturdy and durable, handsome in appearance.Stair can be decomposed into component, and batch production is produced in batches, are transported to each family again and install, and assemble simple and convenient, time saving and energy saving.Stair need not after can dismantle, do not produce any permanent construction rubbish or refuse, help environmental protection.This assembly type stair are suitable for various buildings such as building, villa, also applicable to the provisional or permanent stair of building site or factory, also can be used on various occasions such as boats and ships or mine.

Claims
