Problems solved by technology

However, the direct grouting connection between the prefabricated stairs and the supporting table is prone to cracks, and when tiling or making anti-slip surfaces in the later stage, it is still necessary to manually make a shear-resistant surface or grout to embed anti-slip components, which will not only weaken the strength of the stairs , also slowed down the progress of construction on site

Embodiment Construction

[0012] The present invention will be further explained below in conjunction with the accompanying drawings.

[0013] Such as figure 1 The concrete prefabricated staircase according to the embodiment of the present invention includes a prefabricated staircase 1 and a stepping surface 1-1 of the prefabricated staircase 1, and the stepping surface 1-1 is a water-brushed stone surface. With such a design, the stones on the surface of the step surface are exposed to form a rough surface, and there is no need for manual chiseling and chopping, and post-work such as pasting tiles on the tread surface can be directly done, which greatly shortens the construction period.

[0014] Further, in the above-mentioned concrete prefabricated staircase, the bottoms of both ends of the prefabricated staircase 1 are provided with threaded holes 1-2 for construction and installation. Such as figure 1 As shown, a prefabricated staircase 1 is installed on a supporting platform, which includes an u...

Abstract

The invention relates to the field of building components, in particular to a concrete prefabricated stair. The concrete prefabricated stair comprises a prefabricated stair body and stepping surfaces of the prefabricated stair body, and the stepping surfaces are granitic plaster surfaces. According to the concrete prefabricated stair, the bottoms of the two ends of the prefabricated stair body are provided with threaded holes for construction and installation respectively; the concrete prefabricated stair is high in strength after site construction and installation are conducted, an artificial chiseling chip-axe is not needed for the surface of the stair, later-period work can be directly conducted, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of building components, in particular to a concrete prefabricated staircase. Background technique [0002] In the current staircase construction, the formwork is usually set up on site, the steel bars are bound, the concrete is poured, and the concrete is continuously watered and cured for 14 days to make the concrete strength reach C30. The whole process is labor-intensive, the noise of sewage dust is serious, and there is a lot of garbage. In recent years, the concept of prefabricated stairs has been proposed: the stairs are prefabricated in the factory with tooth plates and formwork, and installed directly after arriving at the construction site. time, greatly shortening the construction period. However, the direct grouting connection between the prefabricated stairs and the supporting table is prone to cracks, and when tiling or making anti-slip surfaces in the later stage, it is still necessary to manually make...
