北京图书馆新馆书报库采用双向密肋楼板,混凝土厚度只有50mm,若在混凝土内埋设管路,交叉处就无法保证楼板的强度;双向密肋间的宽度模数是1200mm,而现在定型的各种日光灯长度,不能满足模数要求。这就在客观上提出了要突破传统(配管敷线吸顶灯具)的要求。为了适应这种建筑结构,我们开发了一种新型产品——金属线槽配线,在线槽上安灯具,能自然地形成光带。金属线槽用1.2mm厚钢板轧制而成,由槽体、槽盖组成封闭型线槽,安装时由线槽与十字盒(四通)、丁字盒(三通)及拐角盒(二通)等组装成,槽内装置的导线用难
The library of the New Library of Beijing Library adopts two-way ribbed floor slabs, and the concrete thickness is only 50mm. If pipelines are buried in the concrete, the strength of the slabs cannot be guaranteed at the intersection; the width modulus of the two-way thick-rib spaces is 1200mm, and now the stereotypes The length of various fluorescent lamps cannot satisfy the modulus requirement. This objectively put forward the need to break through the traditional (pipeline overhead ceiling lamps) requirements. In order to adapt to this kind of building structure, we have developed a new type of product—wire trunking wiring. The lighting fixtures on the in-line groove can naturally form light bands. The wire trough is rolled with 1.2mm thick steel plate. The closed trough is composed of the trough body and the trough cover. The trough and cross box (four-way), T-shaped box (three pass) and corner box (two pass) are installed during installation. ) It is difficult to assemble the wire in the slot device
