In the figure, 1, a stair body; 11. an upper connecting portion; 12. a lower connecting portion; 13. a support body; 131. a fixed part; 1311. a step; 1312. a through hole; 14. a stair tread; 141. a groove; 15. spacing; 16. and connecting the holes.
Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 4, a stair prefabricated member comprises an integrally formed stair body 1, wherein the stair body 1 comprises an upper connecting part 11, a lower connecting part 12, two supporting bodies 13 and stair treads 14 arranged between the supporting bodies 13, an interval 15 is formed between the adjacent stair treads 14, the supporting bodies 13 are not connected, at least one supporting body 13 is provided with a fixing part 131 for mounting a stair, the fixing part 131 is provided with a plurality of steps 1311, each step 1311 is provided with a mounting hole, the upper connecting part 11 is positioned at the top end of the stair body 1, and the lower connecting part 12 is positioned at the bottom end of the stair body 1.
In the utility model, the adjacent support bodies 13 are not connected, so that the interval 15 between the adjacent support bodies 13 can transmit light, the position of the back of the stair can also receive better light, the space utilization rate is provided, and the stair prefabricated member can also be used in houses of small houses.
Design a fixed part 131, can be used for installing the handrail, provide the security of this stair prefab, through the supporter 13 that is located both sides, link together all stair boards 14, fixed part 131 sets up along the supporter 13 outside, can be used for installing the handrail when, improves the intensity of supporter 13. The fixing portion 131 is provided with a plurality of steps 1311 to facilitate installation of the armrest. The whole stair prefabricated member is installed through the upper connecting part 11 and the lower connecting part 12. The installation mode is the same as that of the traditional stair prefabricated member.
Specifically, one of the supporting bodies 13 has a fixing portion 131 thereon. The stair pre-cast member of the fixing portion 131 located on the left side or the right side can be selected according to the actual situation, i.e., the stair pre-cast member is installed against the wall.
Specifically, the two supports 13 each have a fixing portion 131 thereon. When there is no wall on both sides, a stair preform with fixing portions 131 on both sides may be selected.
Specifically, a groove 141 is opened on the lower surface of the stair tread 14. For mounting a light strip.
Specifically, the upper connecting portion 11 and the lower connecting portion 12 each have a width greater than that of the stair tread 14.
