Utility model content
For solving above-mentioned technical problem, the utility model discloses a kind of light steel frame precast stair.
The technical solution of the utility model is:
A kind of light steel frame precast stair, including stair body, the inside of described stair body is provided with steelframe, described
Steelframe includes the main steel plate being obliquely installed, and is located at several the step supports be arrangeding in parallel of the upper surface that main steel plate tilts, with
The upper mounting plate support that the top of main steel plate connects, the lower platform support being connected with the bottom of main steel plate；Described step support with
Main steel plate composition both ends open and cross section are the cavity of triangle；Described upper mounting plate support is that lower surface connects with main steel plate
Connecing, both ends open and cross section are the cylinder of rectangle；Described lower platform support is that upper surface is connected with main steel plate, both ends open
And cross section is the cylinder of rectangle.
Preferably, foam filled layer, the square of upper mounting plate support it are filled with in the cavity of the triangle of described step support
The inner barrel of shape is filled with foam filled layer, and the inner barrel of the rectangle of lower platform support is filled with foam filled layer.
Preferably, described foam filled layer is foam concrete.
Preferably, described foam filled layer is polyurethane foam packed layer.
The beneficial effects of the utility model are:
The inside of the stair body of light steel frame precast stair of the present utility model is provided with interconnective steelframe, connects knot
Structure is firm；Steelframe is formed closes space, is filled with expanded material, while alleviating whole building body, in minimizing in closing space
The noise of body downstairs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1. stair body, 2. main steel plate, 3. step support, the most foam filled layer, 5. upper mounting plate support, 6. time flat
Platform support, 7. go up support platform, 8. descend support platform.
Detailed description of the invention
Below in conjunction with the accompanying drawing 1 in this utility model embodiment, the technical scheme in this utility model embodiment is entered
Row clearly and completely describes, it is clear that described embodiment is only a part of embodiment of this utility model rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, broadly falls into the scope of this utility model protection.
A kind of light steel frame precast stair, including stair body 1, the inside of described stair body 1 is provided with steelframe, described
Steelframe include the main steel plate 2 that is obliquely installed, be located at several the step supports be arrangeding in parallel of the upper surface that main steel plate 2 tilts
3, the upper mounting plate support 5 being connected with the top of main steel plate 2, the lower platform support 6 being connected with the bottom of main steel plate 2；Described platform
Rank support 3 and main steel plate 2 form both ends open and cross section is the cavity of triangle；Described upper mounting plate support 5 is lower surface
Being connected with main steel plate 2, both ends open and cross section are the cylinder of rectangle；Described lower platform support 6 is upper surface and main steel plate 2
Connecting, both ends open and cross section are the cylinder of rectangle.
Foam filled layer 4 it is filled with, in the cylinder of the rectangle of upper mounting plate support 5 in the cavity of the triangle of step support 3
Portion is filled with foam filled layer 4, and the inner barrel of the rectangle of lower platform support 6 is filled with foam filled layer 4.Foam filled layer 4
For polyurethane foam packed layer.
After stair are prefabricated, the polyurethane foam material opening from steelframe two ends being filled into inside, use hanging device will
Stair are placed into setting position, and upper mounting plate support 5 is placed on support platform 7, and lower support platform 8 is placed on lower support platform 8
On.
Certainly, described above is not limitation of the utility model, and this utility model is also not limited to the example above, this skill
Change that the those of ordinary skill in art field is made in essential scope of the present utility model, retrofit, add or replace, also belong to
In protection domain of the present utility model.
