Definitions

  • the present invention relates to a floor structure such as a floor plate bridge structure built on a river or a land, a slab structure of respective hierarchies such as a steel frame building and an iron reinforcement concrete building, a roadbed structure formed on an upper surface of an underground construction, a roadbed structure laid on a ground surface, or the like.
  • Patent Document 1 shows a bridge structure, in which steel stocks each consisting of an upper flange, a lower flange and a web are arranged in parallel, an iron reinforcement is arranged and a concrete is placed between the adjacent steel stocks, i.e., in a space defined by upper and lower flanges of the adjacent steel stocks and the web, and the iron reinforcement concrete and the web are tightly connected to each other by a PC steel stock piercing the iron reinforcement concrete and the web in the width direction of the bridge.
  • the above bridge structure is based on such a designing idea that the bridge strength against an active load such as vehicles is borne by an iron reinforcement concrete placed between the adjacent steel stocks.
  • the slab structure of the respective hierarchies of the conventional steel frame building is formed by supporting a floor plate by beam members
  • the slab structure of the respective hierarchies of the iron reinforcement concrete building is normally formed with a monolithically placed concrete.
  • the roadbed structure temporarily laid on the upper surface of an underground construction employs a method in which iron plates are supported by beam members, and the construction site where trucks and heavy machines frequently come in and out, typically employs a method in which iron plates are merely laid on a ground surface to form a temporary roadbed.
  • Patent Document 1 refers to Official Gazette of Japanese Patent Application Laid-Open No. H08-253912
  • the bridge shown in the above-mentioned Patent Document 1 is a structure in which the integration is achieved by the steel stocks and the iron reinforcement concrete placed at the site, and no consideration is given at all to a unit structure in which the steel stocks are dismantled one by one and re-used.
  • the conventional technique is not suited as a floor structure of a temporarily built bridge and the like.
  • a large scale dismantling operation and a large amount of dismantling expense are required.
  • a great deal of scrap is produced thereby to impair the environment.
  • the form assembling process, the bar arranging process and the concrete placing process are required, thus resulting in increased construction cost.
  • WO 01/31142 A1 describes a wooden floor structure that includes spacer elements in contact with the web of parallel bars.
  • US-A-2112949 shows a floor structure whereby the spacers are formed by poured concrete, and thereby all the features of the preamble of claim 1.
  • an object of the present invention to provide, a bridge floor structure in a floor plate bridge, a floor structure in a steel frame building, a floor structure and an iron reinforcement building, a floor structure on an upper surface of an underground construction, and a floor structure laid on a ground surface, which are capable of solving the above-mentioned problems.
  • a floor structure according to the present invention is defined by claim 1.
  • the floor structure comprises a displacement preventing spacer, the displacement preventing spacer including a left fitting part fitted between the upper and lower flanges of the adjacent left side steel stocks, a right fitting part fitted between the upper and lower flanges of the adjacent right side steel stocks, an upper interposing part interposed between the upper flanges of the adjacent steel stocks, and a lower interposing part interposed between the adjacent lower flanges.

  • right side upper and lower step parts formed at an interlocking part between the upper and lower interposing parts and the right fitting part being engaged with a lower surface of the upper flange and an upper surface of the lower flange of the right side steel stock.
  • the left and right fitting parts are sufficiently spaced from the web to avoid contact therewith.
  • the floor structure further comprises a left displacement preventing block fitted to a space defined between the upper and lower flanges and the web of the adjacent left side steel stocks, and a right displacement preventing block fitted to a space defined between the upper and lower flanges and the web of the adjacent right side steel stocks, mutually opposing side surfaces of the left and right displacement preventing blocks being press butted between the adjacent steel stocks, the individual steel stocks being inhibited from displacing downward due to a surface pressure and a friction engagement between the press butted surfaces.
  • the left and right displacement preventing blocks are formed of a wood, or lightweight cellular concrete or rigid foamed resin.
  • the floor structure is effective as displacement means against an active load in case a floor structure is formed by arranging steel stocks in parallel.
  • the displacement spacer is preliminarily prepared, and the displacement preventing spacer is fitted between the steel stocks which are arranged in parallel. By doing so, the individual steel stocks is effectively prevented from being displaced downward against the active load.
  • the preliminarily prepared left and right displacement preventing blocks are fitted to each steel stock, and two such blocks are merely press butted with each other while arranging the steel stocks in parallel. By doing so, the vertical displacement effect can properly be obtained against the active load.
