[brief description of the drawings]
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the sectional drawing of the light guide structure of the dull and stereotyped daylighting of the utility model embodiment.
Fig. 2 is the partial enlarged drawing at figure I position.
[detailed description of the invention]
The light guide structure of the dull and stereotyped daylighting of the utility model as depicted in figs. 1 and 2, comprises flat dome skylight 1, light pipe 2, diffusing globe device 3, annular base 4 and ground.
Ground comprises bottom 5 and surface layer, and bottom 5 is the ceilings that need the underground space of daylighting, and surface layer comprises basal layer 6 and cement surface layer 7.
Flat dome skylight 1 adopts double-deck doubling tempered glass, and daylighting upper surface is plane.Certainly, this kind of material is only the preferentially selection that this flat dome skylight 1 of guarantee can be realized its effect, and the utility model does not limit the material of flat dome skylight 1.
The installation convex 501 of the bottom 5 oriented upper process on ground, installs the installing hole that has light pipe in convex 501.It is cement convex that convex 501 is installed, and is embedded with bushing pipe 8 in the installing hole of light pipe.Bushing pipe 8 is PE bellows (HDPE double-wall corrugated pipes), and PE bellows is embedded in the endoporus that convex 501 is installed in the time that installation convex 501 is shaped as the inner formword that convex 501 is installed.PE bellows has ensured that the rounding of the installing hole of light pipe cleans, can scratch light pipe.
The annular base 4 of integrative-structure is fixing by multiple expansion bolts 15 with installation convex 501.There is closure gasket groove the bottom surface of annular base 4, is embedded with sealing ring 9 in closure gasket groove.
The hole of holding of flat dome skylight is arranged at the top of annular base 4, flat dome skylight 1 is arranged on holding in hole of dome skylight, the periphery of flat dome skylight 1 and dome skylight hold in the gap in hole and are filled with fluid sealant 10, there is two seals annular groove the bottom surface that dome skylight holds hole, is embedded with sealing ring 11 in two seals annular groove.
Fluid sealant 10, sealing ring 9 and sealing ring 11 can ensure that good sealing is arranged at the top of the light guide structure of dull and stereotyped daylighting, and anti-sealing and dust enter light pipe 2, affect the lighting efficiency of dull and stereotyped daylighting guiding device.
Basal layer 6 and cement surface layer 7 are filled in the periphery that convex 501 and annular base 4 are installed, and the end face of cement surface layer 7 flushes with the end face of flat dome skylight 1, can not affect pedestrian and vehicle pass-through.
The top of light pipe 2 is fixed on annular base 4 dome skylights 1 by erection loop 12 and holds in the endoporus below hole.
Erection loop 12 comprises sleeve pipe 1201, and sleeve pipe 1201 tops comprise outer bead 1202 and inward flange 1203.There is the support holes 401 of an erection loop 12 below that annular base 4 dome skylights hold hole, and the outer bead 1202 of erection loop 12 is supported by the bottom surface of support holes 401.The sleeve pipe 1201 of erection loop 12 is enclosed within the outside of light pipe 2, and the sleeve pipe 1201 of erection loop 12 is fixedly connected with the multiple rivets 13 of light pipe 2 use.The upper end of light pipe 2 embeds in the annular groove of inward flange 1203 bottom surfaces.
The endoporus through bushing pipe 8 of light pipe 2, lower end enters the underground space that needs illumination.
In order to ensure high efficiency of transmission and the stability of sunshine in light pipe 2, the material of light pipe 2 is highly reflective material or inwall through polishing grinding, electroplates high efficiency reflectorized material or post the reflective film of high reflectance.
Diffusing globe device 3 is arranged on the light outlet place of light pipe 2 lower ends, and diffusing device can be prism structure or Fresnel lens structure, and other anyly can make the indoor structure obtaining compared with uniform light.
When the above embodiment of the utility model uses, sunshine sees through dull and stereotyped dome skylight, by the transmission of light pipe, is irradiated on diffusing device, realizes the daylighting of the underground space.Compared with prior art, the above example structure of the utility model is simply compact, and manufacturing cost is low, construction install convenience.
