Description

Technical Field

[0001] This invention relates to the field of optical guide installation technology, and in particular to a fixed installation structure for an optical guide system and its construction method. Background Technology

[0002] During building construction, light pipes are often used to bring natural light into basements and interiors with poor lighting conditions. Generally, light pipe systems have a light cover on the top, which is set on the roof and directly connected to the roof, while the light pipes generally do not extend beyond the roof. However, in order to ensure the lighting effect, the light cover is raised above the roof and cannot be directly connected to the roof. As a result, the light pipes also need to extend beyond the roof. How to ensure the fixation, insulation and waterproofing of the light pipes and the installation of the light cover requires targeted design. Summary of the Invention

The steel sleeve assembly includes a main sleeve pipe, a first flange and a second flange disposed at the bottom of the main sleeve pipe, and a top conversion component disposed at the top of the main sleeve pipe; the first flange and the second flange are respectively disposed on the bottom surface and the top surface of the structural plate; The bottom of the light guide tube extends downward through the opening and the end is positioned corresponding to the position of the ceiling panel. The top of the light guide tube extends out of the steel sleeve assembly and is detachably connected to the light-transmitting cover.

[0005] Furthermore, the first flange and the second flange are vertically connected with corresponding reinforcing ribs, which penetrate the concrete of the slab and are fixedly connected to the slab reinforcement; the first flange and the second flange are arranged in a ring shape, and the ring width is not less than the thickness of the insulation layer.

[0006] Furthermore, the structural slab includes slab concrete and slab reinforcement bars disposed within the slab concrete, wherein the slab reinforcement bars include horizontal longitudinal bars, and the horizontal longitudinal bars are provided in at least two layers, one above the other.
