Activities of the board activities of the board is a kind of light steel skeleton to sandwich panels for the building envelope materials, standard modulus spatial series together, members with bolts, a new concept of environmentally friendly economic activities of the board houses. Can be quickly and easily assembled and disassembled, to achieve a common standardized temporary buildings, and establish a green energy, fast and efficient building concepts, so that temporary housing into a series development, integration of production, matching of supply, inventory and turnaround times using styling products in the field. The so-called "space structure" is a relatively "flat structure" is concerned, it has the characteristics of a three-dimensional effect of the spatial structure can be seen to expand and deepen the planar structure. Since the advent of the spatial structure, with its efficient mechanical performance, new aesthetic forms and quick and easy construction was welcomed. In need large span, stadiums, convention centers, cultural facilities, transportation hubs as well as a large industrial plant space, all saw traces of space structures.
