Description

  The present invention relates to a structure of a building, and more particularly to a structure of a building that takes in light from a certain direction.

  In a relatively large-scale building such as a factory, it is necessary to introduce a relatively large amount of light in order to ensure the brightness in the building. The light to be taken into the building is preferably light from a certain direction, particularly light entering the building from the north side, so that it is possible to take in light with low sunlight and little change in brightness throughout the day.

Conventionally, there is a building having a saw roof as a building that takes in light from a certain direction (see Patent Document 1). In the example shown in FIG. 3, a building 100 having a saw roof includes a plurality of pillars 102 arranged at intervals, and a beam 104 connecting two adjacent pillars 102. The beam height of the beam 104 gradually increases from one end to the other end of the beam 104 so as to form a sawtooth-like roof.
JP-A-62-111058

  A building 100 having a saw roof has two adjacent beams 104a and 104b, and the pillar 102 has a daylighting window 110 between the top 106 of one beam 104a and the top 108 of the other beam 104b. A wall member 112 is attached. A roof plate 114 is attached to the tops 106 and 108 of the beams 104a and 104b. Since the daylighting window 110 faces in a certain direction, the light 116 can be taken from the certain direction through the daylighting window 110.

  By the way, in the building 100 having a saw roof, the range in which the wall member 112 having the daylighting window 110 exists is defined by the top portion 106 of one beam 104a and the top portion 108 of the other beam 104b. For this reason, when designing the building 100 having a saw roof, the beam heights of the beams 104a and 104b must be changed according to the size of the daylighting area. This increases the design effort.

  On the other hand, another conventional building 118 shown in FIG. 4 includes a beam 120 having a constant beam height, a pair of vertical members 124 and 126 fixed to the top of the beam, and a horizontal member connecting the vertical members. 128. One vertical member 124 is provided with a wall member (not shown) having a daylighting window, and light 130 from a certain direction can be taken in through the daylighting window. When the building 118 is designed, the lighting area can be changed without changing the beam height of the beam 120 by changing the height of the pair of vertical members 124 and 126. However, the building 118 requires a large amount of members for securing a desired daylighting area, and the cost for building the building is high.

  An object of the present invention is to provide a building structure that allows more economical design and construction by changing the daylighting area without changing the beam height or without increasing the amount of members. is there.

  The present invention is characterized in that a daylighting section is constituted by an extending member extending in an inclination direction from an inclined end portion of a large beam and an adjacent large beam having an inclined end portion.

  The structure of the building according to the present invention includes at least six columns arranged at intervals in the vertical direction and the horizontal direction, and includes at least three columns arranged in one of the vertical direction and the horizontal direction. Six pillars, each extending in one of the longitudinal and lateral directions, adjacent to one of the pillars and one of the pillars connecting one of the pillars and one of the two pillars adjacent thereto A second large beam connecting the other of the two pillars, each having a top portion comprising a central portion and an end portion inclined so that the beam height gradually increases outward from the central portion. A third girder that extends in the longitudinal and lateral directions and connects two adjacent pillars to the other of the first and second girder, and is the same as the top of the first girder or the second girder A third girder having a substantially horizontal top located at a height; and the first girder The second member excluding an extension member extending from one end portion of the top portion in the inclination direction of the end portion and an imaginary line extending substantially perpendicularly from the extension member to the top portion of the second large beam. A first roofing board disposed on the top of the girder, a second roofing board disposed on the extension member, a third roofing board disposed on the top of the first girder, and the first roofing board. A translucent member disposed between the roof plate and another roof plate. Thereby, light can be taken in from a fixed direction through between the first roof plate and another roof plate.

  The translucent member may be disposed between the first roof plate and the second roof plate, and between the first roof plate and the third roof plate. can do. When the translucent member is disposed between the first roof plate and the second roof plate, the translucent member can be attached to the top of the second beam. Moreover, the structure of the said building can be provided with the connection member which connects the said extension member and the top part of the said 2nd large beam, and the said translucent member can be attached to the said connection member. The lower end portion of the connecting member may be fixed to the central portion of the top portion of the second large beam, or may be fixed to the end portion.

  When the extension member extends from one end portion of the top portion of the first beam to the inclination direction of the end portion, when designing a building, the length of the extension member can be changed by changing the length of the extension member. The length, that is, the distance between the first roof plate and the second roof plate can be changed, and thereby the lighting area of the building can be changed. In order to change the daylighting area, it is not necessary to change the beam height of the first or second large beam.

  Further, the beam height of the second large beam decreases from the column toward the central portion, so that the length of the imaginary line is longer than when the beam height of the second large beam is constant. The length can be increased by the reduction of the beam height. That is, the space | interval of a said 1st roof board and a said 2nd roof board can be enlarged more. Thereby, a larger daylighting area can be secured without increasing the amount of members.

  According to the present invention, economical design and construction can be performed by changing the daylighting area without changing the beam height or increasing the amount of members.

  As shown in FIG. 1, the structure of the building 10 includes a plurality of pillars 12 arranged at intervals in the vertical direction and the horizontal direction on a plane. The plurality of pillars 12 are composed of six pillars including three pillars that are spaced apart in the horizontal direction and the other three pillars that are spaced apart from each pillar in the longitudinal direction. Including. The structure of the building 10 extends in the lateral direction, and includes a first large beam 14 that connects one of the pillars 12b and one of the two pillars adjacent thereto (not shown), one of the pillars 12b, and 2nd large beam 16 which connects the other 12a of two adjacent pillars. The structure of the building 10 includes a third girder (not shown) that extends in the vertical direction and connects two adjacent pillars. The structure of the building 10 is different from the above example in which the first and second large beams 14 and 16 extend in the horizontal direction and the third large beam extends in the vertical direction. May extend in the vertical direction, and the third girder may extend in the horizontal direction. In this case, the structure of the building 10 is composed of six pillars including three pillars arranged at intervals in the vertical direction and the other three pillars each spaced apart from each pillar by the same distance in the lateral direction. A plurality of pillars 12 including these pillars are included.

  The top 18 of the first girder 14 has a central portion 20 and two end portions 22, and each end portion 22 is inclined so that the beam height gradually increases outward from the central portion 20. Further, the top 24 of the second girder 16 has a central portion 26 and two end portions 28, similar to the top 18 of the first girder 14, and each end portion 28 faces outward from the central portion 26. Inclined so that the beam height gradually increases. The tops of the third girder are located at the same height as the tops 18 and 24 of the first and second girders 14 and 16. The top of the third beam is substantially horizontal. That is, it may be horizontal or slightly inclined to provide a gradient for draining rainwater.

  The first girder 14 includes, for example, a first upper chord member 30 and a first lower chord member 32 and a plurality of first diagonal members 34 each connecting the first upper chord member 30 and the first lower chord member 32. The first upper chord member 30 includes a central portion 20 parallel to the first lower chord member 32 and an end portion 22 inclined with respect to the central portion. The first girder 14 may include a first vertical member 36 that connects the first upper chord member 30 and the first lower chord member 32.

  Similarly to the first large beam 14, the second large beam 16 has a plurality of second oblique members that connect the second upper chord material 38 and the second lower chord material 40 to the second upper chord material 38 and the second lower chord material 40. Material 42. The second upper chord member 38 includes a central portion 26 parallel to the second lower chord member 40 and an end portion 28 inclined with respect to the central portion. The second girder 16 may include a second vertical member 44 that connects the second upper chord member 38 and the second lower chord member 40.

  The structure of the building 10 includes an extension member 46 extending from one end portion 22a of the top portion 18 of the first girder 14 in the inclination direction of the end portion. The structure of the building 10 is arranged at the top 24 of the second girder 16 except for the extension member 46 and a virtual line 48 extending substantially perpendicularly from the extension member to the crest 24 of the second girder 16. 1 roof plate 50, second roof plate 52 disposed on the extension member 46, third roof plate 54 disposed on the top 18 of the first beam 14, the first roof plate 50, and others And a translucent member 56 disposed between the roof plates 52 and 54. Thereby, light can be taken in from a fixed direction through between the first roof plate 50 and the other roof plates 52 and 54. The translucent member 56 can be a wall member having a daylighting window, a transparent or translucent wall member, or the like.

  In the illustrated example, the structure of the building 10 includes a connecting member 58 that is disposed along an imaginary line 48 and connects the extension member 46 and the top 24 of the second beam 16, and the translucent member 56 is connected. It is attached to the member 58. Since the translucent member 56 is oriented in a certain direction, the light 60 can be taken in from the certain direction via the translucent member 56. At this time, light from other directions is blocked by the second and third roof plates 52 and 54. For example, when the translucent member 56 is directed to the north side, direct sunlight is not entered into the building 10 because the direct sunlight is blocked by the second and third roof plates 52 and 54.

  Since the extension member 46 extends from the one end portion 22a of the top portion 18 of the first beam 14 in the inclination direction of the end portion, when the building is designed, by changing the length of the extension member 46, an imaginary line 48 is obtained. , That is, the distance between the first roof plate 50 and the second roof plate 52 can be changed, whereby the amount of light taken in can be changed. That is, the lighting area can be changed. For example, at the time of designing a building, as shown in FIG. 2, by extending the length of the extension member 46, the distance between the first roof plate 50 and the second roof plate 52 can be increased. Thus, the daylighting area can be further increased. Further, by further extending the extension member 46 from the example shown in FIG. 2, the daylighting area can be further increased. In this case, the lower end portion of the connecting member 48 is fixed to the central portion 26 of the top portion 24 of the second large beam 16. Thus, when designing a building, it is possible to change the daylighting area without changing the beam height of the first or second large beam 14, 16.

  In addition, since the beam height of the second large beam 16 decreases from the column 12b toward the central portion 26, the length of the virtual line 48 is longer than that when the beam height of the second large beam 16 is constant. The length can be increased by the reduction of the beam height. That is, the distance between the first roof plate 50 and the second roof plate 52 can be increased. Thereby, a larger daylighting area can be secured without increasing the amount of members.

  The translucent member 56 is attached to the top 24 of the second girder 16 between the first roof plate 50 and the second roof plate 52 instead of the illustrated example attached to the connecting member 58. It may be. Moreover, the translucent member 56 is replaced with the said 1st roof board 50 and the 3rd roof board 54 instead of the said example arrange | positioned between the 1st roof board 50 and the 2nd roof board 52. FIG. Between them.

  In the illustrated example, it is possible to economically design and construct by changing the daylighting area without changing the beam height or increasing the amount of members.
