Abstract

The utility model relates to a concrete hollow stairway flight, comprising a coherent and complete stairway flight with a one-body structure which is consisted of a plurality of steps. The concrete hollow stairway flight is characterized in that the steps all take a hollow cavity type structure. The concrete hollow stairway flight of the utility model can adopt stair forming formworks and coordinate with core formworks in a prefabrication way via factory mass production to be manufactured. The stairway flight can not only greatly lighten stair own weight, reduce consumables, save energy, at the same time manufactured stairway flight has smooth surface and low cost, and intensity and load bearing both can satisfy requirement of the save use.

Description

Concrete hollow staristep

Technical field

The utility model relates to a kind of various buildings that are applicable to, comprises concrete construction, steel building and the various outdoor building precast concrete staristep of (as crossing the street bridge), particularly a kind of prefabricated concrete hollow staristep of integral pouring procedure that adopts.

Background technology

Traditional concrete staircase mostly is that cast-in-place outpouring come, and is solid construction.The existing weak point of this structure is that consumptive material is many, own wt is big, and makes at the scene to get up to waste time and energy, and cost is too high, needs 2～3 people to spend about about 4 days time at least as one section common stair and just can finish.

Summary of the invention

The purpose of this utility model provide at above-mentioned existing in prior technology weak point just a kind of sole mass light, save material and the relatively low prefabricated concrete hollow staristep of employing integral pouring procedure of its cost of production.

The purpose of this utility model can realize by following measure:

Concrete hollow staristep of the present utility model comprises the staristep of the coherent complete integral structure that is made of a plurality of steps, and described step is hollow cavity structure.

The shape of cross section of the hollow cavity of step described in the utility model is any one in triangle, circle, quadrangle or hexagon and other the multiple modelling pattern.

If expect the same complete appearance effect, only need that side of staristep of the present utility model (not pasting a side of wall) made the seal type structure and get final product with traditional solid stair.

Concrete hollow staristep of the present utility model can adopt the stair shaping template to cooperate core to produce in enormous quantities through batch production by prefabrication system and be made, this staristep not only can alleviate the stair own wt greatly, reduce consumptive material, energy conservation, staristep surface smoothing, the cost produced simultaneously are low, and intensity, carrying etc. all can satisfy the requirement of using safely.

The specific embodiment

The utility model is further described below with reference to embodiment (accompanying drawing):

Embodiment 1

As Fig. 1, Fig. 2, shown in Figure 3, concrete hollow staristep of the present utility model comprises the staristep 1 of the coherent complete integral structure that is made of a plurality of steps, and described step is hollow cavity structure; Described hollow cavity 2 is along the length direction setting of each step, and the shape of cross section of this hollow cavity 2 is a triangle.

Embodiment 2

Shown in Fig. 4,5,6, the difference of the form of structure of this embodiment and embodiment 1 is that side of staristep (not pasting a side of wall) is the seal type structure.

Embodiment 3

Shown in Figure 7, the difference of the form of structure of this embodiment and embodiment 1 is that the shape of cross section of its hollow cavity 2 is a circular configuration.

Embodiment 4

Shown in Figure 8, the difference of the form of structure of this embodiment and embodiment 1 is that the shape of cross section of its hollow cavity 2 is a hexagonal structure.
