Abstract

The utility model discloses a handrail for an industrial and a civil building staircases. The columnless handrail of a staircase has the technical proposal that the lower part of a handrail bar (1) is provided with a rail bar (2) which is parallel to the handrail bar (1), rails (3) are arranged between the handrail bar (1) and the rail bar (2) at intervals, and the handrail bar (1), the rail bar (2) and the rails (3) are integrally spread in the same vertical plane to form a sawtooth shape which coincides with the staircase. The columnless handrail of a staircase can be made of steels, woods or plastics, and can be installed on site; the columnless handrail of the staircase can change a pole support structure in the prior art, and as a result, the platform area can be reduced, wherein, the maximum area utilization ratio can be kept. The columnless handrail of a staircase has the advantages of labor saving, time saving, firmness and convenient installation.

Description

Columnless handrail of staircase

The utility model discloses the handrail that a kind of building is gone upstairs and is provided with.

At present, industry and civilian construction are gone upstairs and are generally single flight and two types of two races, two race stair use particularly general in industrial construction and dwelling house, the hand rail of two race stair arranges that nature forms stair well, concrete structure be the corner have vertical steel pipe to be welded into equidistant and with arrange height and fix with anchor clamps with steel pole or pipe fitting that the slope of stairs is erected on the step accordingly, the pre-buried welded and installed handrail that is used for, like this, the handrail installation is miscellaneous on the one hand, on the other hand since handrail corner and step gradient section just to depend on set fence post supporting fixing, there is the defective of stable aspect again in this structure that is used for fixing; Moreover the building stair standard width of a room in an old-style house narrows down to 2.4～2.6m relatively more in vogue at present about by 3m gradually, because the existence of stair shaft, it must occupy certain space, makes still to keep the unlikely conception that diminishes of tread width to be restricted when appropriateness is dwindled the standard width of a room in an old-style house.

The purpose of this utility model is to provide a kind of being convenient to install, and the little firm formula balustrade that takes up space is intended to can guarantee again when further appropriateness is dwindled stair standard width of a room in an old-style house size that the actual clear span of stair bench and halfpace increases relatively.

For achieving the above object, the technical solution adopted in the utility model is: the below of bar is provided with railing in parallel, be furnished with railing between bar and the railing at interval, handrail, railing and railing be the whole zigzag that matches with stair integral body that is launched in same vertical guide.

Bar and railing are consistent with its pairing slope of stairs, therefore, the top stair that the top of bar and railing will be adjacent intersect, the stair projecting end is provided with built-in fitting so that install and fix handrail and railing, therefore, whole handrail is easy for installation, good stability, in addition, because the rod member of whole handrail launches in same plane, the stair shaft structure can not occur again, make the relative design aim that increases of the actual clear span that can guarantee staristep and halfpace when further appropriateness is dwindled stair standard width of a room in an old-style house size again be achieved.

Description of drawings

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

Fig. 2, Fig. 3 are that A among Fig. 1 is to view.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 provides the utility model structural representation, shown in Fig. 1 the stair of general general construction, it comprises the first floor initial rise section of Fig. 1 bottom, flat jacking section three parts that rise section and Fig. 1 top that two floors at Fig. 1 middle part begin, three steps of Fig. 1 bottom are to be inlet port place and indoor difference in height, to relate to these three steps and also have handrail to hold in order to step on, as shown in Figure 1, the horizontal quarter butt of initial rise Duan Youyi (5) links to each other with handrail (1 ') and railing (2 '), in the flat section that rises, bar (1) and railing (2) are linked to each other at interval by the railing (3) that is provided with therebetween and constitute an armrest unit, when mounted, armrest unit is linked to each other by montant (4) transition, and the end of jacking section is fixed on the montant (7) of attic platform.Bar (1), railing (2) and railing (3) be the whole zigzag that matches with stair that is launched in same vertical guide.

Referring to Fig. 2, the appropriate position of the projecting end of stair (6) is correspondingly provided with gap or through hole supplies bar (1), and railing (2) and railing (3) pass, and fixing with the built-in fitting welding.Fig. 3 is fixed armrest bar (1), the another kind of form of structure of railing (2) and railing (3), leave the gap between the projecting end of stair in this structure, this gap is slightly larger than the caliber of bar (1), railing (2), and be connected and fixed with it by the built-in fitting that is provided with, at this moment, bar (1), railing (2) and railing (3) all are connected and fixed on built-in fitting, this shows that it installs and fixes very convenient reliable.

But handrail unit piece disclosed in the utility model is made, promptly earlier with bar (1), railing (2) and railing (3) welding fabrication, install at the scene, unary head and the tail place is linked to each other by montant (4) transition, the head and the tail that are adjacent bar (1) and railing (2) are linked to each other by montant (4), are saving of work and time, economical with materials again like this.
