Abstract

The utility model relates to a staircase which can be easily disassembled and assembled. The new staircase comprises a keel which expands inclined and several footplates arranged equally above the keel. Each footplate is arranged on the keel by two connecting parts. The lower head parts of the two connecting parts are fastened to the left and right profiles of the keel respectively, with the upper head parts bend and expand upward and outward in reverse direction to form a plan support surface. The two level support surfaces can be fastened to the bottom of the footplate allowing disassembly. The staircase can be installed and disassembled easily to satisfy the needs of people to change the special layout inside the buildings. The structure is firm and the strained condition is proper. Besides, the liability and security of the utility model are quite high.

Description

A kind of easy-to-dismount stair

Technical field

The utility model relates to the ingredient of building, specifically is meant a kind of easy-to-dismount stair.

Background technology

In building structure such as small-sized dwelling house, double deck, villa, interlayer, factory building, the structure design of stair has played key effect to the ease for use of this building.Usually, need carry out the design of stair, generally with reasonable, the convenient purpose of using as design of space layout according to the concrete structure characteristics of difference building.Existing stair are built with building usually, become the building inalienable part, and therefore, after the building completion, stair are promptly immutable, change the space layout of furniture in the building after, position and space layout that but can not corresponding change stair.Even at the stair that design with a kind of space layout, after building completion, also exist and need adjust, the possibility of layout again, but traditional fixedly stair can not be realized this function.

Chinese patent provides a kind of " Rotary stairway " for No. 00201048.8, its purpose is to make stair to carry out Site Design according to space layout needs and individual aesthetic conceptions, and can adjust various moulding, these stair comprise one group of pedal, the pedal keel, column and balustrade, the pedal keel are laminated mutually by a plurality of bone knots, the big bottom face of last bone knot is hinged by the small end end face of fastening screw and next bone knot, and fix by nut, pedal is fixed on the horizontal panel of bone knot, column is fixed on the pedal, balustrade is connected between each column, by regulating angle, the i.e. moulding of convertible these stair and the least significant end one-level stair position on the ground between bone knot and the bone knot.

This " Rotary stairway " forms between each bone knot of keel and fixes by fastening screw though have dismantled and assembled, as can to change moulding advantage, insufficient strength, and these stair are in use, may relatively rotate between the bone knot, have potential safety hazard.

The utility model content

The utility model provides a kind of easy-to-dismount stair, and its main purpose is to overcome existing fixed stair can not dismounting, install and shortcoming such as can not adjust after inconvenience, the setting; Simultaneously also be in order to overcome dismantled and assembled stair insufficient strength in the prior art, to have the shortcoming of potential safety hazard.

The utility model adopts following technical scheme: a kind of easy-to-dismount stair, the keel and the some pedals of equidistantly being located at the keel top that comprise a diagonally extending, each pedal is removably installed on the keel by two connectors respectively, the bottom of this two connector is connected in left and right two sides of keel respectively, the upper end respectively with opposite direction upwards, outwardly-bent extension, the supporting surface of formation level, the supporting surface of this two level removably is connected in the bottom surface of pedal.Because keel are integral type, be not divided into dismountable multistage, thereby the intensity of keel improve greatly; Each pedal is connected with keel by two connectors, and its syndeton is stressed rationally, can guarantee the reliability and the safety of pedal.

Aforementioned a kind of easy-to-dismount stair, the bottom of its two connector is connected in left and right two sides of keel removably by three groups of bolts, and the horizontal support face that described two connector upper ends form is connected in the bottom surface of pedal respectively removably by two groups of bolts.Can guarantee that by the bolt connection reliable connection is arranged between pedal, connector, the keel, can reach purpose simple in structure, easy accessibility again.

Aforementioned a kind of easy-to-dismount stair, its connector is the strip plates, in it, go up middle side part and be provided with a bar shaped depression of extending along its length direction, its outer, corresponding formation one strip bulge of downside, this structure makes the more reasonable stress of connector, reliability higher.

By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage with prior art: one, can mount and dismount easily, to satisfy the demand that people change the space layout in the building; Two, its Stability Analysis of Structures, stressed reasonable, reliability and safety are higher.

Description of drawings

Fig. 1 is a sectional perspective structural representation of the present utility model, has shown that the one-level step pedal of these stair is removed, the state that the pedal of another grade step keeps;

Fig. 2 is a sectional perspective structural representation of the present utility model, the state when the one-level step that has shown these stair is upwards observed by the below;

Fig. 3 is a sectional perspective structural representation of the present utility model, has shown the state of observing from the side behind this stair dismounting pedal.

Specific embodiment

Referring to figs. 1 through Fig. 3 a specific embodiment of the present utility model is described.

Present embodiment provides a kind of easy-to-dismount stair, referring to figs. 1 through Fig. 3, these stair comprise keel 1 and some pedals 2 of equidistantly being located at keel 1 top of a diagonally extending, the cross section of these keel 1 is a rectangle, each pedal 2 is respectively by two connectors 21,22 are removably installed on the keel 1, this two connector 21,22 bottom is connected to the left side of keel 1 by three groups of bolts 23, right two sides, the upper end respectively with opposite direction upwards, outwardly-bent extension, the supporting surface 211 of formation level, 221, the supporting surface 211 of this two level, 221 removably are connected in the bottom surface of pedal 2 respectively by two groups of bolts 24.

Connector 21,22 is the strip plates, it is interior, upward middle side part is provided with a bar shaped depression 210,220 along its length direction extension, outside it, downside observes, these bar shaped depression 210,220 corresponding formation strip bulges, this structure makes the more reasonable stress of connector, reliability higher.

Because keel 1 are integral type, be not divided into dismountable multistage, thereby the intensity of keel 1 improve greatly; Each pedal 2 is connected with keel 1 by two connectors 21,22, and its syndeton is stressed rationally, can guarantee the reliability and the safety of pedal 2.

Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
