专利汇可以提供Construction method for underground floor专利检索,专利查询,专利分析的服务。并且PURPOSE:To perform efficient building of an underground floor and to place concrete without the use of a construction joint at the underground floor, by a method wherein a structure center pillar having guide rails is erected in a hole bored in a ground, and beam materials are slidably engaged with guide rails. CONSTITUTION:A structure cetner pillar 3 having guide rails 6 is erected in a hole bored in a ground. After a second floor beam material 7 is secured to the portion, projecting from a ground, of the structure center pillar 3, beam materials (a) and (b) are slidably engaged with the guide rails 6, the adjoining beam materials (a) and (b) at the same floor are coupled together by means of an angle brace material 8, and floor plates are placed thereon to assemble a floor slab material. After the already-assembled floor slab for an underlaying floor is lowered along the guide rails 6, a next floor slab material is assembled. Further, after the floor slab materials for from a lowermost floor to a first floor are temporarily secured, in order, in a staged manner, the floor slab materials are secured to the structure center pillar 3, in order, from the floor slab material for an upper floor, and concrete is placed, in order, from an upper floor to a lower floor.,下面是Construction method for underground floor专利的具体信息内容。
