Description

Stair prefab

Technical Field

The utility model belongs to the technical field of buildings, and particularly relates to a stair prefabricated member.

Background

The prefabricated member mainly refers to a concrete prefabricated member, is most widely applied, is usually manufactured into various members by adopting a pre-forming method in the field of construction, and is then transported to the site for construction, so that the construction speed and the working efficiency are improved.

The traditional prefabricated member stair is totally enclosed like a common cast stair, does not have light transmission and is not suitable for small-dwelling houses.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, and provides a stair prefabricated member which has the characteristics of light transmission and cost saving.

The purpose of the utility model can be realized by the following technical scheme:

the stair prefabricated member is characterized by comprising an integrally formed stair body, wherein the stair body comprises an upper connecting part, a lower connecting part, two supporting bodies and stair treads arranged between the supporting bodies, an interval is formed between the stair treads, at least one fixing part for installing a staircase is arranged on each supporting body, a plurality of steps are arranged on each fixing part, a mounting hole is formed in each step, the upper connecting part is located at the top end of the stair body, and the lower connecting part is located at the bottom end of the stair body.

In the above stair preform, the supports are not connected to each other.

In the stair preform, one of the support bodies has a fixing portion on the sand.

In the above stair preform, both the supports have fixing portions thereon.

In the stair prefabricated member, the lower surface of the stair tread is provided with a groove.

In the above stair preform, the upper connecting portion and the lower connecting portion are both wider than the width of the stair tread.

In the above stair prefabricated member, the upper connecting part and the lower connecting part are both provided with connecting holes.

In the stair prefabricated member, the supporting body is provided with a plurality of through holes which penetrate through the supporting body and correspond to the grooves.

Compared with the prior art, the utility model has the following advantages:

according to the stair prefabricated member, the adjacent support bodies are not required to be connected, so that the interval between the adjacent support bodies can transmit light, the position of the back of the stair can receive better light, the space utilization rate is provided, and the stair prefabricated member can be used in a house with small dwelling size.

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.
