Description

  The present invention relates to a wooden wall structure, and more particularly to a wooden wall structure having a large carbon storage effect and a large energy saving effect.

  Generally, a sound insulation wall is installed at a construction site or a noisy place. Although it is possible to use wood for the sound insulation wall, the wooden sound insulation wall is more rapidly deteriorated due to decay than the concrete wall and cannot be expected to have a large carbon storage effect. Therefore, in order to enhance the carbon storage effect on the wooden wall, (1) It is a structure that is not easily decayed. (2) Even used wood can be reused (contributes to long-term fixation of carbon dioxide). (3) It is resistant to drying and shrinkage and does not crack. Furthermore, in order to enhance the energy saving effect, (4) construction is easy. (5) The yield should be good because there are few parts to throw away wood. (6) There is no complicated shape and processing is easy. And (7) Sound insulation is high in order to fulfill the function of the sound insulation wall. Etc. are demanded.

  Patent Document 1 shows a wall structure of a building in which timbers having a trapezoidal cross-sectional shape in the short direction are stacked obliquely. The stacked surface of wood and wood is slanted, making it difficult for rainwater to enter the gap. However, wood requires grooving to connect up and down and mortise plates that fit into the groove, and if both walls are exposed outdoors, the water resistance of the wall on the other side of the wall is uncommon.

  Patent Document 2 shows a building wall structure in which two opposite corners of a square bar are arranged so as to be vertical, and a groove for connection is provided at a corner portion. All four surfaces in the longitudinal direction of the square bar are tilted obliquely to obtain an effect of good drainage and corrosion resistance. However, the upper and lower connecting portions of the square members are not thick and have low sound insulation, and groove processing for connecting the upper and lower ends is necessary.

  Hereinafter, a wooden wall structure according to the present invention will be described with reference to the drawings.

  FIG. 1 is a side sectional view of a wooden wall structure 100 (Example 1) according to the present invention. The wooden wall structure 100 is stacked so that the vertical angles of the plurality of fan-shaped timbers 1 whose cross sections in the short-side direction face each other are configured. The flat surfaces that are fan-shaped side surfaces are brought into surface contact. The stacked surface 13 brought into surface contact is inclined at a half angle (here, 45 degrees) of the apex angle of the sector. A roof 2 for preventing rain was provided on the top of the wall 12, and a concrete ground part 3 having an inclined upper surface was provided on the foundation 10 at the bottom of the wall 12. Since the upper surface of the ground part 3 is inclined, rainwater can be hardly collected. As shown in FIG. 1, since the wooden wall structure 100 is thick, for example, noise coming from the right side is attenuated and goes out to the left side. The wooden wall structure 100 can additionally block airflow. The vertical angle of the sector of the wood 1 is 90 degrees. Such a wood 1 can be obtained by cutting a log in the longitudinal direction and dividing it into four equal parts. Since Example 1 is difficult to break, it is suitable when a large-diameter log is used.

  FIG. 2 is a perspective view of a place where the wood 1 of FIG. The both sides of the wood 1 are inserted into the H steel 5 and stacked. The wood 1 includes a main body portion 14 and drop portions 6 on both sides in the longitudinal direction. The drop portion 6 has a trapezoidal shape on the side surface (that is, a cross-sectional shape in the short side direction), and is dropped between the flange portions 11 of the H steel 5. In a state where the drop portion 6 is dropped between the flange portions 11, the side surfaces of one side of the trapezoid are brought into surface contact with each other. The upper and lower trapezoidal pairs form a parallelogram, thereby filling between the flange portions 11.

  In addition, when the height of the wall 12 is low in FIG. 2, it may be dropped directly into the H steel 5 without providing the drop portion 6 in the wood 1.

  FIG. 3 is a plan view when the wood 1 of FIG. 1 is dropped into the H steel 5. The drop-in part 6 of the wood 1 can be fixed in close contact with the inside of the flange part 11 of the H steel 5 by the fixing bracket 7. If the thickness of the wood 1 is different at the end of the end, the position of the top angle of the fan shape is the same at the center of the log and only the radius is different, so the position of the drop-in part 6 is the same at both ends from the top of the wall To be processed.

  4 is a cross-sectional view taken along line AA in FIG. (A) is the case where the trapezoidal heights of the drop-in portions are all the same, and (B) is the case where two types of trapezoidal heights of the drop-in portions are provided. As shown in FIG. 4A, a rain cap 4 is put on the top of the H steel 5. The side surfaces of the trapezoid hypotenuse of the drop-in portion 6 are in surface contact with each other. The fixing bracket 7 presses the upper side or the bottom side of the trapezoid against the inner wall of the flange portion 11. As shown in FIG. 4 (B), if the drop-in part 6 is pushed in by every other fixing bracket 7, the drop-in part 6 'can also be pushed in. Here, the height of the trapezoid is b <b ′. Note that the trapezoidal width of the drop-in portion 6 may be matched with the flange portion 11 of the H steel 5. By increasing the cut width to the trapezoidal apex angle side of the drop portion 6, the apex angle of the wood 1 can be protruded from the surface of the wall 12 as shown in the middle stage of FIG. 3.

  FIG. 5 is a cross-sectional view of the wood 1 of FIG. 1 in the short direction. The woods 1 are stacked facing each other. Further, the fan-shaped apex angles are stacked so as to protrude from the front surface and the back surface. A raindrop groove 8 extending in the longitudinal direction of the wood 1 is provided on one side of the wood 1. The raindrop groove 8 can drop the rainwater that has gone around the inclined surface as a drop so as not to flow into the stacked surface of the wood. The width of the stacking surface 13 can be changed according to the sound insulation performance.

  FIG. 6 is a perspective view (Example 2) of the wooden wall structure 200 according to the present invention. In the wooden wall structure 200, a plurality of cross-sections in the short-side direction are perpendicularly faced to each other, the long sides of the right-angled triangle are brought into surface contact with each other, vertically shifted so as to be vertical, and stacked. It is configured. Since the wood 1 is shifted up and down, the thickness of the wall 12 can be secured. In Example 2, the right triangle is a right isosceles triangle and the two base angles are 45 degrees. The wood 1 having an isosceles triangle with a right-angled cross section in the short-side direction is obtained by forming a square bar having a square cross-section in the short-side direction from a log and cutting it in the longitudinal direction.

  Both ends of the wood 1 are dropped between the flange portions 11 of the H steel 5 as they are. The drop portion 6 does not require special processing. In the state where the wood 1 is stacked, the corner portions protrude from the front surface and the back surface. A raindrop groove 8 extending in the longitudinal direction of the wood 1 is provided on one side of the wood 1. The raindrop groove 8 can prevent rainwater that has circulated around the inclined surface from falling into a drop so as not to flow into the stacked surface of the wood 1.

  FIG. 7 is a cross-sectional view of a place where the wood 1 of FIG. 6 is dropped between the flange portions 11 of the H steel 5. The interpolation member 9 is dropped when both ends of the wood 1 are dropped between the flange portions 11 of the H steel 5. In the second embodiment, the interpolating member 9 has a right triangle shape on the side surface, and fills the gap between the dropped portion 6 and the flange portion 11 of the wood 1. A set of the upper and lower interpolation members 9 and the drop-in portion 6 forms a parallelogram. The space between the flange portions 11 is filled with parallelograms. Thereby, the wood 1 can be stably attached to the H steel. Since there is no gap, sound can be prevented from leaking through the gap.

  FIG. 8 is a perspective view of a wooden wall structure 300 according to the present invention (Example 3). The wooden wall structure 300 is configured by stacking a plurality of timbers 1 having a square cross section in a short direction so that the timbers 1 face each other and face each other, and the opposite corners of the timbers 1 are positioned on a vertical line. The wall 12 is configured. The wall 12 can be secured to a diagonal length of a square. In the state where the wood 1 is stacked, the corner portions protrude from the front surface and the back surface. A raindrop groove 8 extending in the longitudinal direction of the wood 1 is provided on one side of the wood 1. The raindrop groove 8 can prevent rainwater that has circulated around the inclined surface from falling into a drop so as not to flow into the stacked surface of the wood 1. Wood with a square cross section is easy to reuse. In FIG. 8, the drop-in portions 6 at both ends of the wood 1 have no special processing, and have a drop-down portion 6 in a square shape. Example 3 is suitable for a wooden wall using small-diameter wood obtained from small-diameter wood.

  FIG. 9 is a cross-sectional view of a portion where the wood 1 of FIG. 8 is dropped between the flange portions 11 of the H steel 5. The interpolation member 9 is dropped when both ends of the wood 1 are dropped between the flange portions 11 of the H steel 5. The interpolating member 9 has a right triangle shape on the side surface, and fills the gap between the drop portion 6 and the flange portion 11 of the wood 1. A set of the upper and lower interpolation members 9 and the drop-in portion 6 forms a parallelogram. The space between the flange portions 11 is filled with parallelograms. At the lower part of the wall 12, a concrete ground part 3 having an inclined upper surface is provided on the foundation.

  FIG. 10 is a perspective view of a wooden wall structure according to the present invention. In Example 4, a part of the drop-in part 6 in FIG. 8 is cut out, and the cross section in the short direction is a right triangle. As shown in the drawing circle, in the state where the woods 1 are stacked, the two right triangles become parallelograms and fill the space between the flange portions 11 of the H steel 5, so that the interpolation member 9 is not necessary. The width of the H steel 5 can be smaller than that shown in FIG. The shape of the side surface may not be a right triangle but may be processed to be a trapezoid as shown in FIG. At the lower part of the wall 12, a concrete ground part 3 having an inclined upper surface is provided on the foundation.

  The present invention is suitable as a wooden wall structure having a large carbon storage effect and energy saving effect.
