  • FIGS. [0020] 1 to 4 show a first embodiment of the invention, and FIG. 5 shows a second embodiment, which embodiments are described below.
  • First, an explanation will be given to the first embodiment. [0021]
  • The first embodiment serves to connect [0022] columns 1 and beams 2 which serve as vertical members and horizontal members constituting a building, using a base body 3 provided with second connection portions 5 which are connected to first connection portions 4 provided on building members such as the columns 1 and beams 2, the first connection portions 4 and the second connection portions 5 being structured to be connected to each other by means of a first fitted annular body 6, which is fitted onto an edge of the first connection portion 4 and an edge of the second connection portion 5 for groove fitting, and a second fitted annular body 7 which is further fitted onto the first fitted annular body 6 for taper fitting.
  • An explanation will be given below in detail to respective parts according to an embodiment. [0023]
  • The [0024] base body 3 is a suitable hollow, metallic member shown in FIGS. 1 and 2, four cylindrical portions 8 being formed on the peripheral surface projecting radially, and cylindrical holes 8 c of the cylindrical portions 8 and an inner hole 3 a of the base body 3 being structured to communicate with each other (In addition, while in the present embodiment the cylindrical portions 8 are shown as projecting from the base body 3 in six directions, configurations in which the cylindrical portions project in, for example, one direction, or two orthogonal directions, or three directions, are suitably adopted provided that a feature of the invention is displayed.
  • The respective [0025] cylindrical portions 8 are formed to have a flange 8 b at their edges, the flange facing the base body formed with a groove 8 a. When this groove and flange are butted against a cylindrical portion 9 described later, the groove 8 a and the flange 8 b form the first connection portion 4 which together with a groove 9 a and a flange 9 b (the second connection portion 5) formed on an edge of the cylindrical portion 9 define a grooved portion 10, which enables a part of the inner surface of the first fitted annular body 6 to be fitted onto both the first connection portion 4 and the second connection portion 5.
  • The [0026] cylindrical portion 9 is a suitable metallic member formed as shown in FIGS. 1 and 2, set to the same diameter as that of the cylindrical portions 8 of the base body 3.
  • Also, the [0027] cylindrical portion 9 is foxed at an edge with a flange 9 b, a groove 9 a being formed on the flange facing the base body.
  • Also, the [0028] cylindrical portion 9 is formed at the base end thereof with a fixed attachment piece 9 c, which is to be secured to an end surface of building members such as the columns 1, beams 2, or the like, the fixed attachment piece 9 c being formed with a plurality of holes 9 c′, each of which permits a length of steel threaded rod 11 exposed from an end surface of the building member and enables fixed attachment of the cylindrical portion 9 to the end surface of the building member by screwing a nut 13 onto the steel threaded rod 11.
  • The first fitted [0029] annular body 6 is a suitable metallic member formed to assume a C-shape as shown in FIGS. 1 to 3, cut at one position and possessing elasticity affording slight opening. Accordingly, such elasticity is made use of to allow the first fitted annular body 6 to be fitted onto the grooved portion 10 defined by the first connection portion 4 associated with the cylindrical portion 9 and the second connection portion 5 associated with the base body 3.
  • Also, the first fitted [0030] annular body 6 is formed on its outer peripheral surface with an inclined surface, which is taper press fitted into an inner surface, described later, of the second fitted annular body 7.
  • Also, the first fitted [0031] annular body 6 is formed on an inner peripheral surface thereof with two ridges 6 a.
  • The first fitted [0032] annular body 6 is structured to have its grooves fitted onto the grooved portion 10 to connect both the first connection portion 4 and the second connection portion 5 to each other when it is fitted onto the grooved portion 10 defined by the first connection portion 4 associated with the cylindrical portion 9 and the second connection portion 5 associated with the base body 3. Concretely, the two ridges 6 a are fitted into the depression 9 a and the depression 8 a, and the flange 9 b and the flange 8 b are positioned between the two ridges 6 a.
  • The second fitted [0033] annular body 7 is a suitable metallic member formed to assume an annular-shape as shown in FIGS. 1 to 3, and structured to be preset to a diameter affording fitting the inner surface of the second fitted annular body 7 onto the outer peripheral surface of the first fitted annular body 6 by taper press fitting (a wedging action is generated).
  • Also, in the embodiment, the building members such as the [0034] columns 1, beams 2, or the like are hollow bodies formed from concrete.
  • Concretely, molding of the [0035] columns 1 and the beams 2 is carried out by means of a so-called hollow centrifugal molding technique.
  • The so-called hollow centrifugal molding technique is one, in which a square-shaped form is rotated while concrete placing is performed, and when rotation of the form is stopped and the form is removed, inner [0036] circular holes 1 a, 2 a are formed centrally in the longitudinal direction of the form. A hollow body obtained by the hollow centrifugal molding technique is very rigid since centrifugal forces press the concrete.
  • In the embodiment, the square-cylinder form is used to make the [0037] columns 1 and the beams 2 square in cross section in a direction perpendicular to the longitudinal direction, and the inner holes 1 a, 2 a are circular.
  • Also, in the embodiment, the [0038] columns 1 and he beams 2 are formed to be of a PC concrete structure (prestressed concrete structure), in which steel wires 11 (piano wire, reinforcement, or the like) as tension members are introduced and tensioned, thus making rigid building members of high durability.
  • With a building having a framed structure, in which the [0039] columns 1 and the beams 2 structured in the above manner are used and connected together by a connection device according to the embodiment as shown in FIG. 4, the respective hollow holes 1 a, 2 a, 3 a, 8 c, 9 d in the columns 1, the beam 2, the base body 3 and the cylindrical portion 9 can be also made use of as piping such as gas pipes, water service pipes and a space in which wiring such as electric wires and telephone wires can be placed.
  • The [0040] reference numeral 12 denotes fire resistive covering materials.
  • Since the embodiment is configured in the above manner, the first connection portion [0041] 4 provided on a building member, such as the column 1 and the beam 2 comprising a building, and the second connection portion 5 provided on the base body 3 are caused to approach each other and the first fitted annular body 6 is fitted onto the first connection portion 4 and the second connection portion 5 so that portions of the outer surfaces of the first connection portion 4 and the second connection portion 5 fit into the inner surface of the first fitted annular body 6, and further the second fitted annular body 7 is taper press fitted onto the first fitted annular body 6 so that the first fitted annular body 6 is fixed, thus connecting the respective building members to the base body 3.
  • Accordingly, the building members are rigidly connected to the [0042] base body 3 in a rapid and sure manner.
  • An explanation will be given below to a second embodiment. [0043]
  • According to the second embodiment, a first fitted [0044] annular body 6 composed of a pair of half bodies 6A, 6B is adopted as shown in FIG. 5, and adapted to be fitted onto the grooved portion 10 defined by the first connection portion 4 associated with the cylindrical portion 9 and the second connection portion 5 associated with the base body 3 in such a manner that it sandwiches the grooved portion from right and left.
  • The other features are the same as those of the first embodiment, and so an explanation therefor is omitted. [0045]
