Description
Technical field
The present invention relates to building prefabricated components, is a kind of precast hollow stair.
Background technology
Because cast-in-site stair exist more deficiency, therefore, this area provided the multiple technical scheme that stair product is made in industrialization in factory in recent years, used to be directly installed on building.But this stair are not yet approved by this area at present, its main cause is: pre-stair weight is larger, and handling and install complicatedly make the cost of production of precast stair higher than cast stair.Although the advantage of precast stair is a lot, because it exists handling, complicated deficiency is installed, existing precast stair product cannot be promoted the use of.
Summary of the invention
The object of this invention is to provide a kind of precast hollow stair, it can solve the deficiencies in the prior art.
The present invention for achieving the above object, be achieved through the following technical solutions: a kind of precast hollow stair, comprise stair tread, on stair tread, arrange and mark time, one side of marking time arranges horizontal blind hole, the length direction of stair tread arranges longitudinal blind hole, the opening of blind hole is arranged on the bottom part of stair tread, two hoisting devices are at least set on stair length direction, on hoisting device is arranged on and marks time, two suspenders are distributed on stair length direction, hoisting device has an alignment pin, the length direction of alignment pin and the width of marking time are in the same way, alignment pin is through the through hole of offering on swivel nut lower end, the height of swivel nut is T-shaped with the length of alignment pin and is connected, screwed hole is offered on swivel nut top, screw rod is installed in screwed hole, the outer end of screw rod connects link, alignment pin and swivel nut are embedded in the inside of marking time, link is positioned at the upper surface of marking time.Uniform two at the width of stair of described hoisting devices, uniform two at the length direction of stair.Described longitudinal blind hole is offered four stairway width direction is uniform.On the bottom platform of stair, offer the first taper locating hole, on the higher-end platform of stair, offer the second taper locating hole.The center line of horizontal blind hole and the distance H 1 of marking time between upper surface are 30-60 millimeter, and the center line of longitudinal blind hole and the distance H 2 of marking time between basal surface are 30-60 millimeter.
The advantage of precast hollow stair provided by the invention is: it is ensureing under the prerequisite of stair intensity, weight is lighter, alleviate weight for transporting and installing, the hoisting device arranging makes the handling of stair very convenient, and manufacturing cost is significantly reduced, for the application of precast stair provides wide space.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention; Accompanying drawing 2 is plan structure schematic diagrames of accompanying drawing 1; Accompanying drawing 3 is A-A cross-sectional view in accompanying drawing 1; Accompanying drawing 4 is I portion structure for amplifying schematic diagrames in accompanying drawing 1; Accompanying drawing 5 is II portion structure for amplifying schematic diagrames in accompanying drawing 1; Accompanying drawing 6 is III portion structure for amplifying schematic diagrames in accompanying drawing 1.
Detailed description of the invention
Contrast accompanying drawing, the present invention will be further described.
In figure, 1 is stair tread, on stair tread 1, arrange and mark time 2, 2 the side of marking time arranges horizontal blind hole 5, the length direction of stair tread 1 arranges longitudinal blind hole 7, the opening of blind hole 7 is arranged on the bottom part of stair tread 1, two hoisting devices are at least set on stair length direction, on hoisting device is arranged on and marks time, two suspenders are distributed on stair length direction, hoisting device has an alignment pin 14, the length direction of alignment pin 14 and the width of marking time are in the same way, alignment pin 14 is through the through hole 13 of offering on swivel nut 11 lower ends, the height of swivel nut 11 is T-shaped with the length of alignment pin 14 and is connected, screwed hole 12 is offered on swivel nut 11 tops, the interior installation screw rod 15 of screwed hole 12, the outer end of screw rod 15 connects link 16, alignment pin 14 and swivel nut 11 are embedded in the inside of marking time, link 16 is positioned at the upper surface of marking time.Weight of the present invention is compared with prior art weight reduction 20% left and right, and do not affect the intensity of stair, loading, unloading stair do not need to use complicated suspender, link 16 is directly hung on hook, because hoisting device is distributed on length and the width of stair, very easily by stair handling, transport and install.
The further scheme of the present invention is: uniform two at the width of stair of described hoisting devices, uniform two at the length direction of stair.
Preferred embodiments of the present invention are: described longitudinal blind hole 7 is offered four stairway width direction is uniform.It is reaching under the prerequisite requiring in stair intensity and application life, and weight is the lightest, manufacturing cost is minimum.
The further preferred scheme of the present invention is: on the bottom platform 4 of stair, offer the first taper locating hole 10, offer the second taper locating hole 9 on the higher-end platform 3 of stair.This structure makes the installation accurate positioning of stair, is convenient to fixing reinforcing bar, easy construction.
The center line of horizontal blind hole 5 of the present invention and the distance H 1 of marking time between 2 upper surfaces are 30-60 millimeter, and the center line of longitudinal blind hole 7 and the distance H 2 of marking time between basal surface are 30-60 millimeter.This is the optimal selection scheme that reaches stair step intensity and application life, low cost of manufacture, and be convenient to install, manufacture.In figure, 8 is anti-slip tanks.
