WIND-SNOW PROTECTION PLATE BEARING STRUCTURE OF WIND-SNOW PROTECTION FENCE

摘要

PURPOSE: To fix a wind-snow protection plate slid along posts between the posts by preventing looseness at the time of usage. ;CONSTITUTION: A plurality of wind-snow protection plates 18 are connected between posts 13 through interlocking mechanisms in the vertical direction, and guide rollers 23 and spacers 24 are mounted rotatably on support shafts 21 installed to the side frames 19 of the wind-snow protection plates. The base ends of lower links 26 are pivoted by the support shafts of the wind-snow protection plates at uppermost places, and the base ends of upper links 28 are pivoted by the support shafts of the wind-snow protection plates at lowermost places. The base ends of the upper links and the lower links are pivoted by the support shafts of the wind-snow protection plates in intermediate sections, and projections 25 at the front ends of the lower links are fitted rotatably into slots at the front ends of the upper links of the wind-snow protection plates adjacent in the vertical direction. Engaging members 30 are installed to the lower sections of the side frames of the wind-snow protection plates with the exception of the wind-snow protection plates at the lowermost places, and the engaging members are interposed among hold-down walls 31 mounted in the vertical direction in response to the guide walls 22 of the guide rollers and the spacers. The wind-snow protection plates at the lowermost places are fixed onto the posts by stoppers 41 from the side frames of the wind-snow protection plates at the lowermost places.;COPYRIGHT: (C)1996,JPO
