用工程塑料制作的平面或空间网格结构
摘要：
本实用新型公开了一种用工程塑料制作的平面或空间网格结构，它包括由上弦杆、下弦杆和腹杆连接构成的平面或空间网格结构，它是将构成平面或空间网格结构的上弦杆、下弦杆和腹杆采用工程塑料制作，并通过熔焊的连接方式连接工程塑料制作的上弦杆、下弦杆和腹杆，并将工程塑料制作的平面或空间网格结构的上弦杆和下弦杆之间的距离制作为整个平面或空间网格结构跨度的1/10～1/8，从而使工程塑料制作的平面或空间网格结构的刚度能满足平面或空间网格结构的技术规程要求。本实用新型不仅能带来很好的经济效益，而且对建筑节能，保护环境节约森林资源均有深远意义。
摘要（英）：

The utility model discloses a plane or space lattice structure which is made from engineering plastics, which comprises a plane or space lattice structure which comprises an upper chord member, a lower chord member and a web member, wherein the upper chord member, the lower chord member and the web member which are made into the plane or space lattice structure are made from the engineering plastics, the upper chord member, the lower chord member and the web member which are made from the engineering plastics are connected through the connecting mode of welding, the distance between the upper chord member and the lower chord member of the plane or space lattice structure which is made from the engineering plastics is 1/10-1/8 of the span of the whole plane or space lattice structure, thereby the rigidity of the plane or space lattice structure which is made from the engineering plastics is capable of meeting the technical standard requirement of the plane or space lattice structure. The utility model not only is capable of bringing excellent economic benefit, but also has profound significances for saving energy for buildings, protecting environment and saving forest resources.
