Background technology
Occur a kind of novel lighting material sunlight board in recent years, generally be used for various architectural lightings roof and indoor decorating; The railway terminal and the wait Room, airport and overpass, passage ceiling; The top cover of public service facility such as bus station, ferryc terminal and decoration small garden ornaments; Skylight, cellar, arch roof and market ceiling; Tourism, the strange decoration of recreation occasion and the Room, rest corridor; Heat insulation and the noise barrier billboard ad of printing opacity, lamp box advertisement; Fields such as senior inner fitting plate.
Existing sunlight board is dull and stereotyped mostly, and normal width is 2100mm.As shown in Figure 1, during construction, sunlight board 11 is laid on the support 17; Consider the waterproof demand; Above the seam crossing 12 between sunlight board 11 and the sunlight board 11, lay adhesive waterproof tape 14, and go up jewelling alloy arc voltage bar 13, and cooperate waterproof self threading pin 15; In addition, also need seal along seam crossing 12 hitting property silica gel 16.Mounting means is complicated, and along with the expanding with heat and contract with cold of sunlight board 11, seam crossing 12 can occur loosening, and neutral silica gel 16 also can wear out with adhesive waterproof tape 14 gradually, and drainage will be more and more outstanding.
In addition, can also adopt H type aluminium alloy extrusions that sunlight board is carried out assembly unit.Because section bar is a straight flange, clamping force is not enough, gets loose easily.And both materials are different, and the coefficient of expansion is different, must reserve effective space in the link slot so that sheet material receives to expand and the stand under load displacement.
Therefore, still needing provides a kind of novel connector, not only can closely connect the two boards material, and it is loosening that it is difficult for, and simple, anti-leaking also should be installed, and is prone to draining.
