Definitions

  • the present invention relates to an architectural technique for facilitating designing of a structural strength and for improving a fireproof capability while ensuring an attractive exterior appearance in wooden building members such as posts and beams which structure frameworks of a wooden building or architecture.
  • Patent Document 1 frameworks of wooden buildings or architectures are structured by suitably jointing wooden building members, such as posts and beams.
  • the posts and the beams of the wooden building members are such important members that receive various loads, such as own weight of a building, and external forces applied due to deposited snow, wind and earthquake.
  • Patent Document 1 Japanese Laid-open (Kokai) Patent Application Publication No. H08-151683
  • a wooden building member includes: an elongated structural portion having a rectangular cross-section, and configured to receive a load applied thereto; a coating portion with which at least three sides of the cross section of the structural portion are coated over an entire length of the structural portion; and an insulating portion which is interposed between the structural portion and the coating portion in a laminated manner and prevents the load applied to the structural portion from being transmitted to the coating portion.
  • a coating portion is exposed to blaze, and carbonization gradually progresses from its outer periphery to its inward portion.
  • an insulating portion in the inward portion appears. Since a structural portion is covered with the insulating portion, the structural portion is not exposed directly to blaze and the carbonization progresses very slowly, and thus the structural portion is not burned down in a short time.
  • the surfaces of the wooden building members are coated with the coating portion, the insulating portion is not exposed to the outside, and its exterior appearance can be ensured.
  • the fireproof capability can be improved. Since various loads applied to the wooden building are received mainly by the structural portion, the designing of the structural strength is facilitated while the fireproof capability is ensured, and further, even if the coating portion is completely burned down, the building does not collapse.
  • FIGS. 1 and 2 illustrate a wooden building member according to a first embodiment achieved by applying the present invention to a post which is made of a laminated lumber.
  • a post 10 whose member axis extends in a vertical direction comprises: an elongated structural portion 12 having a rectangular cross-section; and configured to receive a load applied thereto; a coating portion 14 with which a periphery of the cross-section of the structural portion 12 is coated over an entire length of the structural portion 12; and an insulating portion 16 which is interposed between the structural portion 12 and the coating portion 14 in a laminated manner and prevents the load applied to the structural portion 12 from transmitting to the coating portion 14.
  • the structural portion 12 is arranged to have any cross-sectional area depending on various loads applied to the post 10 and is made of a laminated lumber which is obtained by laminating laminar materials in parallel, which laminar materials are severed into a predetermined dimension, and bonding them with synthetic resin adhesive to form one integral part.
  • the coating portion 14 has a predetermined thickness t in the cross section of the post 10 and, similarly to the structural portion 12, the coating portion 14 is made of a laminated lumber which is obtained by laminating laminar materials in parallel, which laminar materials are severed into a predetermined dimension, and bonding them with synthetic resin adhesive so as to form one integral part.
  • the insulating portion 16 is composed of a noncombustible material or an incombustible material prescribed by the Building Codes in Japan.
  • the noncombustible material includes a gypsum board with thickness of 9 mm or more (thickness of board base paper is 0.6 mm or less), a wood wool cement board with thickness of 15 mm or more, a hard wood chip cement board with thickness of 9 mm or more (bulk specific gravity is 0.9 or more), a wood chip cement board with thickness of 30 mm or more (bulk specific gravity is 0.5 or more), a pulp cement board with thickness of 6 mm or more, and the like.
  • the incombustible material includes a incombustible laminated wood with thickness of 5.5 mm or more, a gypsum board with thickness of 7 mm or more (thickness of board base paper is 0.5 mm or less), and the like.
  • the insulating portion 16 can be achieved by using the inexpensive base material having high fire-retardant reliability which is widely used in a building or architecture.
  • the insulating portion 16 is fixed or semi-fixed to a periphery of the structural portion 12 by a weak bonding system, concretely, nailing, synthetic resin adhesive or the like, so that various loads applied to the structural portion 12 are prevented from being transmitted.
  • a function of the post 10 will be described below.
  • the coating portion 14 is exposed to blaze and carbonization gradually progresses from its outer periphery to its inward portion.
  • the insulating portion 16 positioned on an inner side of the coating portion 14 appears, and the progression of the carbonization is stopped.
  • the structural portion 12 is covered with the insulating portion 16 made of the noncombustible material or the incombustible material, it is not exposed directly to the blaze and the carbonization progresses very slowly, and thus the structural portion 12 is not burned down in a short time.
  • the gypsum board is not exposed to the exterior, and thus appearance of the post 10 can be ensured. For this reason, while the exterior appearance of the post 10 is ensured, the fireproof capability can be improved. Since the loads applied to the wooden building are received mainly by the structural portion 12, the designing of the structural strength is facilitated while the fireproof capability is ensured and further, even if the coating portion 14 is entirely burned down, collapse of the building does not occur.
  • the predetermined thickness t of the coating portion 14 is set according to a carbonizing speed of the base material (laminated lumber) so that it is not burned down at least for one hour from the beginning of firing.
  • the predetermined thickness t may be set to 48.0 mm or more (0.8 x 60). In this way, since it takes at least one hour for the coating portion 14 to be completely burned down, a possibility that the building collapses before fire extinction is greatly reduced, and the efficiency as "the fireproof construction" of Japanese building codes, which is very difficult to achieve with a wooden post, can be provided.
  • FIGS. 3 and 4 illustrate a wooden building member according to the second embodiment achieved by applying the present invention to a beam which is made of a laminated lumber.
  • a beam 20 whose member axis extends in a horizontal direction comprises: an elongated structural portion 22 having a rectangular cross section, and configured to receive loads applied thereto; a coating portion 24 with which three sides of the cross section of the structural portion 22 are coated along the entire length of the structural portion 22, and an insulating portion 26 which is interposed between the structural portion 22 and the coating portion 24 in a laminated manner and prevents the load applied to the structural portion 22 from transmitting to the coating portion 24.
  • the beam 20 has the constitution which is functionally similar to that of the post 10, but since one surface corresponding to one side of the cross section of the structural portion 22 should receive various loads, only both side surfaces and a lower surface each corresponding to the three sides of the cross section of the structural portion 22 are coated with the coating portion 24.
  • an upper surface of the structural portion 22 is bonded to, for example, a floor material 30 made of a noncombustible material or the like, and thus is not exposed directly to blaze at the time of a fire. Even if the coating portion 24 and the insulating portion 26 are not provided on the upper surface of the structural portion 22, the fireproof capability of the beam 20 is not adversely influenced.
  • the structural portion 22, the coating portion 24 and the insulating portion 26 are made to be integral by using a conventionally known fastening member 28 composed of a bolt and a nut. Since the other parts of the constitution, function and effect are similar to those of the post 10, the description about the post 10 should be referred to.
  • At least one of the structural portion and the coating portion is constituted by a noncombustible liquid-impregnated wood building material
  • an aluminum foil is stuck to at least a joint appearing in an outer peripheral surface of the noncombustible material or the incombustible material that is connected by joining for composing the insulating portion.
  • heat exerted on the joint of the noncombustible material or the incombustible material can be partially reflected, so that the carbonization of the structural portion can be further slowed.
  • heat acting on the outer peripheral surface can be partially reflected, so that the progression of the carbonization of the structural portion can be effectively repressed.
  • a general laminar material composing a laminated lumber is severed from a round log by conversion of timber as shown in FIG. 5 .
  • the grain of the laminar material is "edge grain” as shown in FIG. 6
  • the grain becomes "flat grain” as shown in FIG. 7 .
  • the directional fire resistance efficiency of the laminar material is verified. As the grain is denser, the carbonizing speed is slower, and thus the laminar material is preferably arranged so that the edge grain appears on the outer peripheral surface of the wooden building member.
  • the laminar material is arranged so that a long side of the cross section of the laminar material extends approximately perpendicularly to respective sides defining the cross section of the structural portion 12 and their extended lines, thereby constituting the coating portion 14.
  • the edge grain appears on the outer peripheral surface of the post 10, and the fireproof capability can be more improved.
  • the flat grain appears on the outer peripheral surface of the post 10, but since that portion is not positioned in the approximately perpendicular direction with respect to the respective sides defining the cross section of the structural portion 12, no adverse influence directly acts on the fireproof capability of the post 10.
  • the coating portion 14 can be constituted by suitably combining laminar materials having the same dimension, and thus this is advantageous in, view of the stock management, the cost and the like. Further, since the length of each of the sides forming the cross section of the laminar material is reduced, as many laminar materials as possible can be severed from one round log, thereby reducing the cost of the wooden building members.
  • the structural portion and the coating portion composing the wooden building member may be constituted by a solid material or by combining a laminated lumber and a solid material.
  • the predetermined thickness t of the coating portion may be set to 60.0 mm or more (1.0 x 60) because its carbonizing speed is about 1.0 mm/min.
  • the present invention can be applied not only to posts and beams as the wooden building members but also to braces, joists and the like.
