Definitions

  • This invention relates to a method of constructing a housing structure of the kind referred to in the precharacterizing portion of Patent claim 1. Such a method is known from GB-A-1579569.
  • the period of construction work in which a housing structure of an atomic power station is constructed can be shortened by promptly building the housing structure for housing therein equipments used to effect atomic power generation, and by installing such equipments within the housing structure at an earlier time.
  • a conventional method of constructing a housing structure of an atomic power station comprises, as shown in Fig. 1, the steps of digging the ground; vertically disposing, in the digged hole, side wall units 1, 2 which consists of steel-bar reinforced concrete; horizontally arranging temporary beams 3 supported on a number of support frames 9; framing concrete mould 4 on the temporary beam 3; disposing anchor bolts 5, sleeve 6, built-in pieces 7, iron bars 8, etc. in the concrete mould 4; and pouring concrete into the concrete moulds 4, leaving the immature concrete as it is until a sufficiently high strength of the concrete is obtained. It further comprises the steps of, thereafter, collapsing the support frames 9 and taking these frames 9, temporary beam, concrete mould, etc. away from an area enclosed by the side wall units 1, 2 and the deck panel obtained as above, and then carrying the atomic power equipments into this area for installation.
  • a method of constructing a housing structure having side wall units, partitioning walls, a pre-fabricated deck panel and equipments which are to be installed within the space enclosed by said wall units dand said deck panel comprising the steps of installing said equipment within said space after erecting said side walls and thereafter, placing said deck panel above said space on said side wall units.
  • the object of the invention is to provide a method of constructing a housing structure, which makes it possible to complete the entire facilities of an atomic power station including equipment, housing structure, etc., within a period shorter than that in prior art methods.
  • side wall units 1, 2 are made of reinforced concrete and constitute strength members of a housing structure of a nuclear reactor.
  • built-in support pieces 10 are burried in the side wall units, 1, 2, respectively, which reside in the vicinity of their top portions, with their surfaces exposed.
  • brackets 11 whose tops are horizontally flattened are welded to the built-in support pieces 10, respectively.
  • equipments 12 and pipes 13 are carried inside of the side wall units 1 and 2. The equipments 12 and pipes 13 are lifted by a crane and carried into a space between the side wall units 1 and 2 through overhead opening.
  • a girder or beam 14 made of steel is lifted and horizontally held by the crane, and then is lowered onto the brackets 11.
  • the beam 14, thereafter, is mounted on the brackets 11 at both ends by means of bolts 28 shown in Figs. 5 and 6. In this way, the beam 14 is supported by the side wall units 1 and 2.
  • the deck panel 22 is lifted and horizontally held by means of a balance 24 which has been lifted by a crane. Thereafter, the deck panel 22 is lowered onto the beam 14. When lowered, the deck panel 22 is positioned by operating the crane, in such a manner that its one side edge is lapped upon a corresponding one side edge portion of the upper surface of the beam 14 as shown in Fig. 5. Another opposing deck panel 22 is similarly positioned on the beam 14 with a gap L interposed therebetween as shown in Fig. 5. In this way, a space G, which is surrounded by the upper surface of the beam 14 and the respective side faces of the two deck panel 22, is formed. Iron bars 25 are protruded from the side faces of the deck panel 22 into this space G.
  • horizontal iron bars 26 are also arranged, as required, above the beam 14 perpendicularly to the iron bars 25.
  • vertical iron bars 29 are arranged, as required, with their ends screwed into the beam 14.
  • a housing structure for housing equipment 12 is constructed.
  • this structure construction method it is not necessary to erect a number of support frames for supporting the temporary beam, and the weight of concrete used to make the deck panels nor to prepare any concrete moulds. Further is not necessary to collapse such support frames and take them away. Besides, since such support frames are not erected on such an installation place during the construction of a housing structure, the installation of the equipment 12 can be started at a time earlier than in the prior art construction method, so that an atomic power station is completed earlier. Further, according to this construction method, no concrete mould is required separately. As seen, in the method according to the present invention, the causes of prolonging the period of construction are greatly decreased.
  • the equipments 12 and pipes 13 can be carried inside of the side wall units 1 and 2 from above before a deck panel or ceiling is not constructed, their entry can be promptly effected and large-sized equipments can be easily taken in. These features also helps to shorten the construction period.
  • the deck panel 22 is mounted with various equipments in advance, the work for mounting equipments on the upper and lower surfaces of the deck panel 22 at an elevated place is not necessary, resulting in more safety of work and a shorter period of construction.
  • the deck panel 22 is prepared in advance in a convenient place other than at the actual construction site, no maturing time of concrete is required at the actual spot of installation. Thus, it is possible to start installing other equipment and the subsequent operations involved in the construction of the housing structure, immediately after the pre- fabricated deck panel has been installed. This is also helpful to shorten the construction period.
  • the space G is formed by arranging the beam 14 and the two deck panels 22 as show in Fig. 5.
  • a prefabricated partitioning wall unit 30 made of reinforced concrete is lifted by a crane and then is placed above the space G.
  • This partitioning wall unit 30 has the following structure. As shown in Fig. 7, the wall unit 30 is formed interiorly with a concrete supply passage 31 and an air vent 32, each of which is opened at one end thereof at a corresponding side surface of the wall unit 30 and at the other end thereof at the lower end surface of the wall unit 30. Further, as shown in Fig.
  • partitioning wall unit 30 having a thickness smaller than the width L of the space G can be erected stably on this space G, whereby the working efficiency is increased.
  • iron bars 35 protruding downwards from the lower end face of the partitioning wall unit 30 is allowed to project into the space G, within which they perpendicularly intersect the steel bars 25 protruding from the side surfaces of the two deck panels 22 into the space G.
  • a concrete fluid is poured into the space G, thereby joining together the two deck panels 22, beam 14 and partitioning wall unit 30 into an integral combined unit.
  • the fluid concrete is introduced into the space G through the concrete supply passage 31, and the air in the space G is expelled through the air vent 32. Accordingly, the space G can be completely filled with concrete.
  • the brackets 34 are taken away if required, the bolt 33 is withdrawn, and concrete is injected into the empty bolt hole to blind the same.
  • the beam 14 is utilized later for receiving other pipes or equipments. Further, the upper surface of the structure is covered with mortar and shape to have a camber, when required. This mortar finishing operation may be performed either before or after the equipments installation.
  • the deck panel 22 is desired to be lifted or transferred stably with its attitude maintained horizontal.
  • the deck panel 22 is suspended with several ropes including diagonally crossing ropes with each other, as shown in Fig. 8, for preventing lateral motion of the wall unit.
  • a metal fitting 38 shown in Fig. 9 is mounted in order to secure the ropes 37.
  • This metal fitting 38 comprises an anchor portion 39 buried in the concrete body of the deck panel 22 and formed with a female screw 40, and a metal ring 41 including a male screw 42 for engaging with the female screw 40 of the anchor portion 39.
  • the male screw portion 42 is disengaged from the female portion 40, thereby removing the lifting metal ring 41 from the deck panel 22.
  • a flat deck panel surface having no protruding metal pieces is obtained, so that the installation of equipment thereonto can be effected without hindrance.
  • the deck panel is not fabricated at an elevated place on the construction site, safety is guaranteed. Besides, no concrete mould is required for joining the deck panels 22. Furthermore, since the deck panel is prepared at a place well equipped, not only the productivity but also the quality of the panel can be improved at the same time.
