由于地方性预制构件厂的生产和运输条件的限制,以及考虑到构件制作和运输成本的情况,目前有些全装配建筑工地采用现场预制钢筋混凝土构件,这就产生了在工地内如何选定钢筋混凝土构件预制场地的问题.通常在布置钢筋混凝土构件预制场时,工地内的运输道路基本上已先布置,而需要预制构件的地方是由施工对象的建筑位置决定的.这样一来,问题就成为在道路固定和需要构件的地点(简称需点)固定的条件下如何选定构件的预制场地(简称供点).
Due to the restrictions on the production and transportation conditions of local prefabricated component factories, and the considerations of component production and transportation costs, some prefabricated reinforced concrete structures are currently used on fully assembled construction sites. This has resulted in the selection of reinforced concrete on the site. The problem of prefabricated site of components. Usually when laying prefabricated sites for reinforced concrete components, the transport roads within the site are basically arranged first, and the place where prefabricated components are needed is determined by the construction site of the construction object. In this way, the problem becomes How to select the prefabricated site of the component under the condition that the road is fixed and the location of the required component (abbreviated as point) is fixed (abbreviated as supply point).
