Implement a kind of precast concrete stair of the present utility model and have following beneficial effect:, surface area water can be concentrated and discharge, thereby avoid the stair surface area water by drip being set at the stair upper surface.A kind of precast concrete stair of the present utility model can be applicable to different occasions such as indoor, outdoor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of a kind of precast concrete stair embodiment of the present utility model;
Fig. 2 be among Fig. 1 the precast concrete stair along the sectional drawing of 1-1;
Fig. 3 be among Fig. 1 the precast concrete stair along the sectional drawing of 2-2.
The specific embodiment
The utility model passes through at the prefabricated drip of the upper surface of precast concrete stair, thereby avoids the stair surface area water, effectively gets rid of potential safety hazard.
As shown in Figure 1, be the schematic diagram of the embodiment of precast concrete stair of the present utility model.In the present embodiment, precast concrete stair 10 comprise stage portion and the support portion that is formed by the steel concrete one-time-concreting.Wherein support zone is in the two ends of stage portion, and it has the soffit of level (perhaps part of horizontal), thereby can be erected at the assembling that realizes precast concrete stair 10 on brace summer or the ground.Stage portion comprises at least one step plate 11 (there is shown 3 step plates).Certainly, the support portion also can be used as a step plate, and perhaps a step plate with the end is considered as the support portion.Be provided with drip in above-mentioned stage portion and/or support portion upper surface, this drip is the wire casing 14 through stage portion and support portion length direction.
In the present embodiment, wire casing 14 is positioned at the both sides of the edge of stage portion and support portion upper surface, as shown in Figure 1.In actual applications, also can only use wire casing 14 in a side of stair.For the ease of cleaning, above-mentioned wire casing 14 has curved bottom.Especially, the degree of depth of wire casing 14 is that 5-30 millimeter, width are the 5-30 millimeter.
In order further to increase drainage effect, the upper surface of stage portion and support portion can be made as in advance to wire casing 14.
In order to realize that the precast concrete stair are connected with the firm of other parts of building, guarantee the intensity of building, also be embedded with the structure (not shown) that connects the building body in the support portion, for example perpendicular to the sleeve pipe (reinforcing bar of in sleeve pipe, pegging graft when assembling these precast concrete stair) of support portion end face.In addition, connecting the structure of building body can also be to expose the reinforcing bar of end or upper and lower surface.
