Exhibition.Relatively more mainly due to Building Trade in China field fabrication, cause that waste of material demand many, artificial is many, construction cost is high, execute
Work cycle length etc..As I crosses the development of market economy, the name of " housing industrialization " is fade-in ear curtain, and fast-developing,
The development of prefabrication is increasingly becoming development trend.Stair are as structural elements very important in Residential structure
One of, play an important role in the process promoting housing industrialization.Therefore improve to stair mounting structure that extremely have must
Want.
Content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of lighter weight, group
It is convenient to close, and intensity higher damping precast stair.
The purpose of this utility model can be realized by following technical proposal: a kind of damping precast stair, including upper mounting plate,
Lower platform and precast stair, it is characterised in that: also including steel skeleton, described steel skeleton includes substrate and is located at substrate both sides
Floor, and substrate top is fitted in bottom precast stair, in the embedded described precast stair of the floor at substrate top, described is upper
Being respectively equipped with pre-embedded steel slab on platform and lower platform, described pre-embedded steel slab is provided with the embedded groove coordinating with floor, and prefabricated
In the floor of the corresponding base plate bottom in stair two ends can coordinate embedded described embedded groove, and precast stair is made to be erected at upper mounting plate
And between lower platform.
Owing to steel skeleton includes substrate and is located at the floor of substrate both sides, substrate top is fitted in bottom precast stair, base
The floor at plate top embeds in precast stair, and therefore overall lightweight structure design, and bulk strength increases, and passes through precast stair
The floor of the corresponding base plate bottom in two ends assembles in coordinating embedded embedded groove so that install very convenient.
In above-mentioned a kind of damping precast stair, described steel skeleton is some H profile steel composition, described H profile steel bag
Including web and being located at the wing plate of web both sides, the corresponding wing plate of some H profile steel is bonded to each other fixing, and web is concordant simultaneously arranges shape
Becoming described steel skeleton, and some webs forming the described corresponding substrate of steel skeleton, some wing plates form the rib of substrate both sides
Plate.
Therefore existing H profile steel can be utilized to be combined using.
In above-mentioned a kind of damping precast stair, described embedded groove groove depth is less than the height of base plate bottom floor, and
The floor of base plate bottom can be embedded in embedded groove, and makes to be formed between described substrate and pre-embedded steel slab to pour gap.
In above-mentioned a kind of damping precast stair, described pour gap in be filled with cement mortar.
By making to connect more stable pouring gap filling concrete mortar.
Compared with prior art, the utility model has the advantage that
Owing to steel skeleton includes substrate and is located at the floor of substrate both sides, substrate top is fitted in bottom precast stair, base
The floor at plate top embeds in precast stair, and therefore overall lightweight structure design, and bulk strength increases, and passes through precast stair
The floor of the corresponding base plate bottom in two ends assembles in coordinating embedded embedded groove so that install very convenient.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As Figure 1-4, a kind of damping precast stair of the utility model, including upper mounting plate the 1st, lower platform and precast stair 2,
Also including steel skeleton 21, steel skeleton 21 includes substrate 22 and is located at the floor 23 of substrate 22 both sides, and substrate 22 top is fitted in
Bottom precast stair 2, the floor 23 at substrate 22 top embeds in precast stair 2, upper mounting plate 1 and lower platform is respectively equipped with pre-buried
Steel plate 11, pre-embedded steel slab 11 is provided with bottom the embedded groove 12 coordinating with floor 23, and the corresponding substrate in precast stair 2 two ends 22
Floor 23 can coordinate embedded embedded groove 12 in, and make precast stair 2 be erected between upper mounting plate 1 and lower platform.
Further, steel skeleton 21 forms for some H profile steel 24, and H profile steel 24 includes web 25 and is located at web 25 both sides
Wing plate 26, the corresponding wing plate 26 of some H profile steel 24 is bonded to each other fixing, and concordant setting of web 25 forms steel skeleton 21 simultaneously,
And some webs 25 forms the corresponding substrate of steel skeleton 21 22, some wing plates 26 form the floor 23 of substrate 22 both sides.Embedded groove
