Abstract
The utility model discloses and provides that a kind of structure is simple, the spiral stairs toroidal frame of use safety.The utility model comprises the interior toroidal frame (1), outer ring frame (2) and the some pedals (3) be arranged between described interior toroidal frame (1) and described outer ring frame (2) that vertically arrange, spiral web (4) composition that described interior toroidal frame (1) and described outer ring frame (2) are mutually permanently connected by two sections, described spiral web (4) is made up of some bended pipes welded side by side (5).The utility model is applicable to stair and manufactures field.
Description
Technical field
The utility model relates to a kind of stair, particularly relates to a kind of spiral stairs toroidal frame.
Background technology
Stair are main settling modes of one of building vertical transportation, for traffic connection during environment larger with difference in height between floor.Stair of the prior art have many types, and spiral stairs is type relatively more conventional in daily life.Spiral stairs is commonly referred to spirality or winding stairs, because its streamline is handsome in appearance, saves space and very popular, is often used in office premises, residential building or vest pocket park and factory.Spiral stairs in traditional handicraft is normally arranged around a single-column, and plane is rounded, and its platform is fan-shaped plan with marking time, and inboard width of marking time is very little, and forms the steeper gradient, dangerous during walking, and complicated structure; Simultaneously by structure influence, the stress point of these type of stair only has single-column one, and when people's walking is outside it, pedal is in vibrating state, there is potential safety hazard.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides that a kind of structure is simple, the spiral stairs toroidal frame of use safety.
The technical scheme that the utility model adopts is: the utility model comprises the interior toroidal frame, outer ring frame and the some pedals be arranged between described interior toroidal frame and described outer ring frame that vertically arrange, the spiral web composition that described interior toroidal frame and described outer ring frame are mutually permanently connected by two sections, described spiral web is made up of some bended pipes welded side by side.
Further, upper cover plate is provided with above described pedal, be provided with lower cover below described pedal, described upper cover plate and described lower cover both sides are all fixedly installed on described interior toroidal frame and described outer ring frame, and profile is consistent with described interior toroidal frame and described outer ring frame.
Further, described pedal is steel pedal or wooden pedal or cement pedal.
Further, the diameter of described interior toroidal frame is less, and the diameter of described outer ring frame is less.
Further, described bended pipe is rectangular steel tube.
The beneficial effects of the utility model: because the utility model comprises toroidal frame, outer ring frame and some pedals be arranged between described interior toroidal frame and described outer ring frame in vertically setting, the spiral web composition that described interior toroidal frame and described outer ring frame are mutually permanently connected by two sections, described spiral web is made up of some bended pipes welded side by side.Compared to the spiral stairs in the middle of prior art, the utility model does not arrange single-column, but by described interior toroidal frame and described outer ring frame itself as supportive body, effectively avoids stressed too concentrated; Described spiral web is combined to form by some described rectangular steel pipes simultaneously, simplifies the difficulty that large area steel bend.So the utility model structure is simple, use safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of described spiral web;
Fig. 3 is the structural representation of described pedal.
Detailed description of the invention
The utility model comprises the interior toroidal frame 1, outer ring frame 2 and the some pedals 3 be arranged between described interior toroidal frame 1 and described outer ring frame 2 that vertically arrange, described pedal 3 is steel pedal or wooden pedal or cement pedal, in the utility model, described pedal 3 selects steel pedal.The spiral web 4 that described interior toroidal frame 1 and described outer ring frame 2 are mutually permanently connected by two sections forms, because the section area of the described spiral web 4 of the whole stair of required support is larger, technique is difficult to the curvature bent to needed for spiral stairs, so described spiral web 4 is made up of some bended pipes 5 welded side by side, in the utility model, described bended pipe 5 selects rectangular steel tube.The diameter of described interior toroidal frame 1 is less, and the diameter of described outer ring frame 2 is less.
Upper cover plate 6 is provided with above described pedal 3, lower cover 7 is provided with below described pedal 3, described upper cover plate 6 and described lower cover 7 both sides are all fixedly installed on described interior toroidal frame 1 and described outer ring frame 2, and appearance curve is consistent with described interior toroidal frame 1 and described outer ring frame 2.
The utility model is applicable to stair and manufactures field.
