Description

Stair and handrail that industry and civilian construction are used

The present invention relates to the fitting-out work of building, specifically is the stair and the handrail thereof of building.

In the design scheme of the present industrial construction and the staircases and handrails of residential houses and the concrete engineering, stair are generally single flight and run two types with two, it is particularly general that two race stair use in dwelling house, its railing arranges that nature forms stair shaft, concrete scheme be the corner have vertical steel pipe to be welded into equidistant and with arrange height and fix with anchor clamps with the steel part that the ladder gradient is erected on the step accordingly, pre-buried, cutting, the welded and installed handrail, like this, make on the one hand the loaded down with trivial details complexity of site operation program, set fence post supporting because handrail just depends in corner and step gradient section on the other hand, and the wild effect of handrail appears again in this structure that is used for fixing inevitably; Moreover the dwelling house stair standard width of a room in an old-style house narrows down to 2.6m and 2.4m relatively more in vogue at present about by 3m gradually, because the existence of stair shaft, it must occupy certain space, makes 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 object of the present invention is to provide the little firm formula balustrade of a kind of duty, be intended to 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.

To achieve these goals, the technical solution adopted in the present invention is: stair and handrail that industry and civilian construction are used, stair constitute flap-like by prefabricated component, the handrail that is installed on the stair comprises bar and fence post, its feature part is that every section unsettled end of stair has along the terraced aspect outside that flat stretching exceeds adding of stair standard width of a room in an old-style house center line 0-0 and stretch plate, this adds the lower end of stretching plate gap, the adding of the opening position of opening stretched plate plate bottom side the fixture of burying underground wherein, bar be by with the corresponding to initial rise section of the floor number of plies, the flat section that rises, the jacking segment unit joins end to end from bottom to top and constitutes, bar along extend on the terraced aspect adding on the stair of upper strata stretch the plate place and from described gap, pass through and on, the fixture of bar and above-mentioned opening position is fixedly connected, bar is launched into up and down in the vertical guide at stair standard width of a room in an old-style house center line 0-0 place and terraced sloping respective saw teeth shape, and the guardrail post splits to add at bar and stair to be stretched between the plate.

The present invention is applicable to single flight or two race stair, it has changed the traditional design general layout of multilayer stair in the prior art, promptly changed the constant pattern of stair shaft formula handrail design, make the relative design aim that increases of the actual clear span that can guarantee stair bench and halfpace when further appropriateness is dwindled stair standard width of a room in an old-style house size again be achieved, therefore, the present invention compared with prior art has outstanding substantive distinguishing features; In addition, the present invention compared with prior art has significant technological progress, and this mainly shows the following aspects: one, and the every handrail fence post unit among the present invention can process in batch, on-the-spot burst assembling, thus overcome the defective of the loaded down with trivial details complexity of site operation program in the prior art; They are two years old, bar relies on and to add that the fixture stretched on the plate fixes among the present invention, to rely on fence post be diverse as the fixing scheme of supporting to bar in it and the prior art, at some in particular cases, in the fire ladder as highrise building, then can not establish fence post, the supporting of bar disclosed in this invention is still firm especially; Its three, beneficial effect of the present invention also is embodied in materials and saves, and takes up an area of also to reduce, thereby the stair cost is also obviously reduced.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the enlarged drawing at B place among Fig. 1;

Fig. 3 is that K among Fig. 2 is to view;

Fig. 4 is I among Fig. 1-I sectional view.

The embodiment that gives below in conjunction with accompanying drawing does further to describe in detail to the present invention.

Embodiment

Fig. 1 provides side portion structure schematic diagram of the present invention, shown in the figure the two race formula stair in multilayer residential houses, it comprises the initial rise section of first floor, the flat liter section that two floors begin, and top jacking section three parts, three steps of drawing bottom are to be inlet port place and indoor difference in height, to relate to these three steps and also hold up bar to hold in order to make to step on, as shown in the figure, initial rise section stair (1) bottom promptly begins to be provided with bar (2), this section bar (2) need not to be provided with fence post (3), the A point is the supporting-point of initial rise section bar (2), bar (2) stretches out the suitable height of initial rise section tread, turn back oppositely and to extend the B place that adding of epimere stair (1) stretch plate (4) along terraced sloping direction, and be fixed at the B place, so continue to stretch and enter two to ladder slope, upper edge, three and the flat liter section of upper floor, be top jacking section at last, bar (2) end is fixed in the platform place or body of wall of top floor, each section of balustrade bar (2) can be slightly different according to attractive in appearance with practical principle in the structure of bending part, for easy for installation, it is split type that bar (2) is made each unit, it can adopt steel pipe or other material, the supporting welding fixed point of bar (2) seldom brings great convenience to site operation.As seen from Figure 1, bar (2) expands into zigzag up and down between whole ladder layer, and bar (2) launches in the vertical guide of the center of the stair standard width of a room in an old-style house.The gradient of its each section bar (2) is corresponding with the gradient of stair (1).

Fig. 2, Fig. 3 illustrate bar (2) and add the structure of stretching intersection between the plate (4), being bar (2) stretches the U type opening position of being opened on the plate (4) and passes through and mistake from adding, in Fig. 2, bar (2) adds the fixture of stretching on the plate (4) (5) and is fixedly connected with being embedded in, fixture (5) is arranged at the bottom of the plate of figure U-shaped opening position, both are welded to each other and get final product, and the space for the hand steered mistake of people is arranged between bar (2) and the described U type gap.

Now the two race stair with comparatively desirable 2.3m standard width of a room in an old-style house 4.6m depth are example, according to a conventional method, (with reference to 33 pages of " building structure structure data collection " first volumes of publishing in China Construction Industry Press May nineteen ninety) bends up to grade surface with 6 distribution bars of Φ in bench lengthening, choose center line with the thick concrete prefabricated board of 60mm, constitute to add as shown in Figure 2 and stretch plate (4), bury the sample bar underground as supporting, carrying over the gradient of marking time exceeds 10mm and makes the dash line, simultaneously referring to this structure of Fig. 4, easy construction can effectively be controlled the discrepancy in elevation of marking time again when casting stair.

With reference to figure 1, except that fence post (3) the burst assembly welding of top layer platform and the bench that links to each other, the flat fence post (3) that rises section constitutes rhombus or climbs ingot-shaped, unifies assembling.

Technique scheme only with two race stair as embodiment, therefore for straight stair, its scheme is known for the common technique personnel, repeats no more.
