However, the diagonal member fixing bracket described in the above patent document is not easy to use, and there is room for improvement.

For example, those of Patent Documents 1 to 3 do not have a function of receiving the diagonal member because the diagonal member fixing portion for connecting and fixing the diagonal member is a vertically oriented surface.

Further, although Patent Document 4 has a diagonal member receiving portion for receiving the diagonal member, the diagonal member receiving portion receives the edge of the diagonal member, so that the end of the diagonal member is received in advance. It was necessary to process the part into the required shape with high accuracy.

In Patent Document 5, since the diagonal member fixing portion for connecting and fixing the diagonal member did not have a positioning function, it is necessary to install the diagonal member while adjusting the position in the longitudinal direction, and the diagonal member must be installed. It took time and effort to install it accurately.

Therefore, the present invention mainly aims to solve the above-mentioned problems.

In order to solve the above problems, the present invention has a flat plate-shaped building fixing portion fixed to the upper part of the building structure in the diagonal material fixing metal fittings installed on the upper part of the building structure to fix the diagonal material. A diagonal member receiving portion that is erected upward from the building fixing portion and receives the lower surface of the diagonal member, and a diagonal member fixing portion that is located on the side portion of the diagonal member receiving portion and connects and fixes the diagonal member. Further, the diagonal member is guided in the vertical direction, and the diagonal member guide portion capable of positioning the diagonal member in the longitudinal direction is provided in the diagonal member fixing portion, and the diagonal member receiving portion is high. It is characterized by having two receiving surfaces having different surfaces .

<Structure> The configuration will be described below.

FIG. 1 is a perspective view showing a roof 2 of a building 1 such as a detached house. This roof 2 has a horizontal roof surface 3 (horizontal roof surface or land roof surface) having a substantially rectangular shape in a plan view in the center, and four roof surfaces 4 (horizontal roof surface or land roof surface) inclined downward with a downward slope around the horizontal roof surface 3. It is a dormitory roof with a sloping roof surface). The roof surface 3 located at the center is not limited to a horizontal and flat one, and may be, for example, a quadrangular pyramid. Further, the roof shape having four roof surfaces 4 (sloping roof surfaces) inclined on a downward slope is not limited to the hipped roof. The four roof surfaces 4 are made distinguishable by adding (E), (W), (S), and (N), which outline the north, south, east, and west directions, if necessary.

The four inclined roof surfaces 4 form a corner ridge 6 in which two adjacent roof surfaces 4 have a ridgeline that descends diagonally and are combined in a mountain shape. The corner ridge 6 is a roof 2 such as a hipped roof, and is a ridge (corner ridge) inclined toward the corner, which is formed in a portion where the roof surfaces 4 are in contact with each other. Or, it is a ridge that descends diagonally at the corner of roof 2.

The inclined roof surface 4 has a substantially trapezoidal shape in a plan view. Each trapezoidal roof surface 4 is appropriately combined with a triangular roof panel 7 located on both sides thereof and a single or a plurality of square roof panels 8 located between the triangular roof panels 7. It is configured. However, the triangular roof panel 7 may be, for example, a trapezoidal roof panel 7 as long as the corner ridge 6 can be formed. As shown in FIG. 2, the corner ridge 6 is formed by joining triangular roof panels 7 located on both sides of each roof surface 4. However, the inclined roof surface 4 does not necessarily have to have a panel structure composed of roof panels 7 and 8.

Then, as shown in FIG. 3, the inclined roof surface 4 is configured by using the inclined member 11. The diagonal member 11 is mainly used as a structural material for constituting the roof surface 4, and for example, a vertical frame member constituting a frame portion of a triangular roof panel 7 or a square roof panel 8. And so on. Further, the diagonal member 11 may be a member other than the vertical frame member of the roof panel. Wood, metal, or the like is used for the diagonal member 11. In this embodiment, the diagonal member 11 is used as timber.

Such diagonal lumber 11 uses diagonal lumber fixing brackets 15 to 17 for the building structure 12 constituting the building body (or the building frame) and the roof structure 13 (or the hut assembly member) constituting the roof 2. Is fixed. Although the slanted lumber fixing brackets 15 to 17 are made as roof mounting brackets, they have a structure that can be used for the slanted lumber 11 other than the slanted lumber 11 constituting the roof 2.

The diagonal lumber fixing brackets 15 to 17 include the diagonal lumber fixing bracket 15 on the water side attached to the upper part of the roof structure 13, the oblique lumber fixing brackets 16 and 17 on the eaves side attached to the upper part of the building structure 12, and the like.

There are corner metal fittings or end metal fittings (oblique member fixing metal fittings 17) attached to the end portion (or the corner portion of the building structure 12) of the beam portion 18 in the above.

Of these, the diagonal member fixing bracket 15 on the water side can be, for example, as shown in FIGS. 4 and 5. The diagonal member fixing bracket 15 on the water side can be used by combining two diagonal member fixing brackets 15 (R) and diagonal member fixing brackets 15 (L), which are different from each other on the left and right sides, and has a roof structure. It is attached to each of the four corners of the body 13 in a state where two are combined.

The slanted lumber fixing bracket 15 on the water side includes a roof fixing portion 21 fixed to the upper part of the roof structure 13, a slanted lumber receiving portion 22 attached to the roof fixing portion 21 and receiving the lower surface of the slanted lumber 11. It is located on the side portion of the slanted lumber receiving portion 22, and has a slanted lumber fixing portion 23 for connecting and fixing the slanted lumber 11.

Here, the roof fixing portion 21 is formed by bending a vertically oriented metal plate so as to form a plurality of surfaces along a folding line extending in the vertical direction 25, and one of the surfaces 21a is a roof structure. It is abutted against the pillar portion 13a constituting the body 13 and is fastened and fixed in the lateral direction by a fastener 26a such as a bolt or a nut. Further, when two diagonal lumber fixing brackets 15 on the water side are combined, the surfaces 21b of the left and right roof fixing portions 21 that come into contact with each other are fastened and fixed laterally by fasteners such as bolts and nuts to be integrated. Can be done. A washer, a spring washer, or the like can be appropriately used for fasteners and fixtures such as bolts and nuts. Further, screw holes and the like can be appropriately provided in the portions where the fasteners such as bolts and nuts are attached.

The slanted lumber receiving portion 22 simultaneously receives the vertical frame material (diagonal lumber 11) constituting the triangular roof panel 7 and the vertical frame material (diagonal lumber 11) constituting the square roof panel 8. It has a complicated planar shape in which a triangular surface 22a and a square surface 22b are combined so that the surface 22a can be formed.

The diagonal member fixing portion 23 is separately provided for each of the surfaces 22a and 22b of the diagonal member receiving portion 22 (slanting member fixing portions 23a and 23b). The diagonal member fixing portion 23 has a vertical surface portion that rises from the outer side of the diagonal member receiving portion 22 (each surface 22a and a surface 22b), and a lateral portion that is bent from the upper part of the vertical surface portion to the opposite side of the diagonal member receiving portion 22. It has a face portion. In this case, the mounting bracket 11a (for example, an L-shaped bracket) attached to the side surface of the diagonal member 11 is fastened and fixed to the side surface portion of the diagonal member fixing portion 23 in the vertical direction 25 with fasteners such as bolts and nuts. , The diagonal member 11 is attached. However, the method of attaching the diagonal member 11 to the diagonal member fixing portion 23 is not limited to the above.

The diagonal member receiving portion 22 and the diagonal member fixing portion 23 can be formed of a single (almost laterally oriented) metal plate. The diagonal member receiving portion 22 can be welded and fixed to the upper end portion of the roof fixing portion 21 configured as a separate member and integrated.

In contrast to the above configuration, this embodiment has the following configuration.

(1-1) First, the diagonal member fixing brackets 16 and 17 (on the eaves side) according to this embodiment will be described with reference mainly to FIG.

The diagonal member fixing brackets 16 and 17 on the eaves side are flat plates fixed to the upper part of the building structure 12, for example, as shown in the example of the diagonal member fixing bracket 16 (intermediate bracket) in FIG. 7A (or FIG. 7B). A building fixing portion 31 having a shape, a diagonal member receiving portion 32 standing upward from the building fixing portion 31 and receiving the lower surface of the diagonal member 11, and a diagonal member 11 located on the side of the diagonal member receiving portion 32. It has a diagonal member fixing portion 33 for connecting and fixing the above. Further, the diagonal member fixing brackets 16 and 17 on the eaves side have a diagonal member guide portion 34 capable of guiding the diagonal member 11 in the vertical direction 25 and positioning the diagonal member 11 in the longitudinal direction.

Here, as described above, the building fixing portion 31 is abutted from above against the intermediate portion, the end portion, and the like of the upper beam portion 18 of the building structure 12, and is vertically 25 by the fasteners 26b such as bolts and nuts. It is fastened and fixed to. The upper beam portion 18 of the building structure 12 is a lateral U-shaped beam member 18a (shaped steel) as shown in FIG. 7A and a C-shaped beam member 18b (C channel material) as shown in FIG. 7B. ) And other things. The beam member 18a in FIG. 7A is mainly used as a ceiling beam of a building unit to be described later. Further, the beam member 18b in FIG. 7B is mainly used as an eaves extension eaves beam or the like.

The diagonal member receiving portion 32 is assumed to have a vertical surface portion 35 extending upward from the edge portion of the building fixing portion 31, and a horizontal surface portion 36 bent and formed on the upper portion of the vertical surface portion 35. Of these, the vertical surface portion 35 has at least a length necessary to prevent the fastener 26b from interfering with the horizontal surface portion 36 when attaching the fastener 26b such as bolts and nuts to the building fixing portion 31. ing.

Further, the lateral surface portion 36 is bent upward of the building fixing portion 31 so as to cover (at least a part of) the upper portion of the building fixing portion 31, and is along the lower surface of the lower end side (eave side) of the diagonal member 11. It is said to be an oblique receiving surface (inclined receiving surface) having a different angle. The diagonal member receiving portion 32 is assumed to have a width dimension of approximately an integral multiple or more of the lower surface of the diagonal member 11 as a whole. The building fixing portion 31 and the diagonal member receiving portion 32 are integrally provided so as to have a substantially J-shape or the like facing sideways when viewed from the side.

The lumber fixing portion 33 is a member extending upward higher than the lumber receiving portion 32, which is juxtaposed on one side or both sides of the lumber receiving portion 32 and the building fixing portion 31 along the upper surface of the beam portion 18. ing. The diagonal member fixing portion 33 is provided at least integrally with the building fixing portion 31. The diagonal member fixing portion 33 has a substantially U-shaped cross-sectional shape facing the side opposite to the building fixing portion 31 when viewed from above in order to have the required strength. The diagonal member fixing brackets 16 and 17 on the eaves side have a shape that can be formed by bending a single metal plate.

The web portion 33a of the U-shaped diagonal member fixing portion 33 can come into contact with the side surface of the diagonal member 11. Further, the flange portions 33b and 33c of the U-shaped diagonal member fixing portion 33 may be formed to have the same width, but may have different widths from each other. In this embodiment, the flange portion 33b located on the outside (outdoor side) of the building structure 12 is wider than the flange portion 33c located on the inside (indoor side) of the building structure 12.

The diagonal member guide portion 34 can be provided with respect to the diagonal member fixing portion 33 (web portion 33a). The diagonal member guide portion 34 is mainly configured as a guide groove portion extending downward from the upper end portion of the web portion 33a of the diagonal member fixing portion 33, or an elongated U-shaped cut portion extending in the vertical direction 25. ..

This guide groove portion moves the diagonal member 11 up and down by dropping the support shaft portion 38 (FIG. 6) laterally attached to the lower end side of the diagonal member 11 inward in advance from above and guiding the diagonal member 11 downward. It is intended to be locked and held in the direction 25 or the like. The guide groove portion has a width substantially the same as the diameter of the support shaft portion 38. The guide groove portion preferably has a length until the lower surface of the diagonal member 11 abuts on the upper surface of the lateral surface portion 36 of the diagonal member receiving portion 32. At the same time, by guiding the support shaft portion 38 in the vertical direction 25, the diagonal member 11 is naturally positioned in the longitudinal direction. The longitudinal direction of the diagonal member 11 is the extending direction of the diagonal member 11.

For the support shaft portion 38, bolts or the like longer than the width dimension of the diagonal member 11 can be used. Then, after the support shaft portion 38 is guided by the diagonal member guide portion 34, the nut 38a or the like is screwed to the support shaft portion 38 to finally fix the diagonal member 11 to the diagonal member fixing portion 33. Further, when the diagonal member 11 is finally fixed, a joint metal fitting 39 having a substantially U-shaped plan view inside the diagonal member fixing portion 33 having a substantially U-shaped plan view in the diagonal member fixing metal fittings 16 and 17 and the like. The joint metal fitting 39 and the flange portions 33b, 33c of the diagonal member fixing portion 33 may be fixed by a fixing tool 26c such as a bolt or a nut.

The above is a configuration common to the diagonal member fixing brackets 16 and 17 on the eaves side.

Hereinafter, a configuration peculiar to the diagonal member fixing bracket 17 (end bracket) on the eaves side installed at the upper corner of the building structure 12 will be described.

(1-2) As shown in FIGS. 8 and 9 (mainly, see FIG. 9), in the diagonal member fixing bracket 17 (end bracket), the diagonal member receiving portions 32 have different heights (or height differences). It may have two receiving surfaces 42, 43 (having 41).

Here, the receiving surfaces 42 and 43 of the diagonal member receiving portion 32 can have the same height, respectively, but if necessary, as described above, they have different heights and have a height difference of 41. Can be made. The heights of the receiving surfaces 42 and 43 are set according to the shape or structure of each roof surface 4, the height relationship of each roof surface 4, and the like. In FIG. 9, one receiving surface 42 is higher than the other receiving surface 43, but the height relationship between the receiving surfaces 42 and 43 is not limited to this. Also in this case, each of the receiving surfaces 42 and 43 has a width dimension that is an integral multiple or more of the lower surface of the diagonal member 11.

The height difference 41 between the two receiving surfaces 42 and 43 of the diagonal member receiving portion 32 is mainly set by the vertical surface portion 35 (by making the heights different). Therefore, in order to make the receiving surfaces 42 and 43 different in height, the two receiving surfaces 42 and 43 are separated from each other and with respect to the vertical surface portions 35a and 35b formed independently (or separated) from each other. It will be provided. The building fixing portions 31a and 31b can also be formed separately in accordance with the receiving surfaces 42 and 43 and the vertical surface portions 35a and 35b, respectively.

(1-3) The diagonal member receiving portion 32 may have two receiving surfaces 42 and 43 having different gradients 51 and 52 (gradient 51 <gradient 52 or gradient 51> gradient 52).

Here, the gradients 51 and 52 of the receiving surfaces 42 and 43 of the diagonal member receiving portion 32 can be the same as shown in FIGS. 10A to 10E (gradient 51 = gradient 52), if necessary. Can also be different as described above. The angles (gradients 51 and 52) of the receiving surfaces 42 and 43 of the diagonal member receiving portion 32 are set by the bending angles of the receiving surfaces 42 and 43 with respect to the vertical surface portions 35a and 35b. The angles of the receiving surfaces 42 and 43 of the diagonal member receiving portion 32 can be set according to the shape or structure of each roof surface 4, the slope of each roof surface 4, and the like.

(1-4) The two receiving surfaces 42 and 43 may be oriented so as to be orthogonal to each other (see FIGS. 9 and 10C).

Here, it is assumed that the two receiving surfaces 42 and 43 can simultaneously receive the diagonal members 11 constituting the adjacent roof surfaces 4. Therefore, the two receiving surfaces 42 and 43 can be installed at the ends of the two orthogonal beams (beam portions 18) forming the corners of the building structure 12 or at positions in the vicinity thereof. (See Fig. 8).

The building fixing portions 31a and 31b connected to the two receiving surfaces 42 and 43 are integrally connected by a rectangular flat surface portion 31c. The flat surface portion 31c may cover the upper end portion of the pillar portion 61 that supports the end portions of the two beam portions (beam portions 18).

(1-5) The roof 2 is configured by using the diagonal lumber fixing brackets 15 to 17. Hereinafter, the roof 2 configured by using the diagonal member fixing brackets 15 to 17 will be described.

The roof 2 may have, for example, a horizontal roof surface 3 and four inclined roof surfaces 4, as shown in FIG. 1, but the four inclined roof surfaces 4 may be, for example, FIG. 11. As shown in the above, the field plate 71 attached to the upper part of the diagonal member 11, the roofing material 72 (waterproof sheet) attached to the upper part of the field plate 71, and the roofing material 73 installed on the upper part of the roofing material 72 are provided. Can be.

Then, as shown in FIG. 3, the roof surface 4 of such a roof 2 can be constructed by using the slanted lumber fixing metal fittings 15 to 17 and the slanted lumber 11. In the figure, the vertical frame members of the roof panels 7 and 8 constituting the inclined roof surface 4 are the inclined members 11. The slanted lumber fixing brackets 16 and 17 on the eaves side are used to fix the eaves side portion of the slanted lumber 11 to the building structure 12 (the upper beam portion 18).

(1-6) As shown in FIG. 12, the roof 2 described above has at least two sloping roof surfaces 4 constituting the corner ridge 6, and two sloping roofs located on both sides of the corner ridge 6. The solar cell panel 91 may be installed only on one of the surfaces 4.

Here, the roof 2 described above has four inclined roof surfaces 4, and the solar cell panel 91 can be installed on at least one of the four inclined roof surfaces 4. For example, as shown in FIG. 12A, the solar cell panel 91 can be provided only on the roof surface 4 (S) on the south side of the roof 2. In this case, the roof surface 4 (N) on the north side, the roof surface 4 (E) on the east side, and the roof surface 4 (W) on the west side are roof surfaces 4 without the solar cell panel 91.

As shown in FIG. 12B, the solar cell panel 91 can be provided on the roof surface 4 (S) on the south side and the roof surface 4 (W) on the west side. In this case, the roof surface 4 (N) on the north side and the roof surface 4 (E) on the east side are roof surfaces 4 without the solar cell panel 91.

As shown in FIG. 12 (c), the solar cell panel 91 can be provided on the roof surface 4 (E) on the east side and the roof surface 4 (S) on the south side. In this case, the roof surface 4 (N) on the north side and the roof surface 4 (W) on the west side are roof surfaces 4 without the solar cell panel 91.

As shown in FIG. 12 (d), the solar cell panel 91 can be provided on the roof surface 4 (E) on the east side, the roof surface 4 (W) on the west side, and the roof surface 4 (S) on the south side. In this case, the roof surface 4 (N) on the north side is the roof surface 4 without the solar cell panel 91.

Then, as described above, by providing the solar cell panel 91 on the roof 2, a corner ridge 6 is formed in which the roof surface 4 having the solar cell panel 91 and the roof surface 4 having no solar cell panel 91 are adjacent to each other. .. In the corner ridge 6 where the roof surface 4 having the solar cell panel 91 and the roof surface 4 not having the solar cell panel 91 are adjacent to each other, as shown in FIGS. 8 and 13A, two receiving surfaces 42 having different heights. It is preferable to use the diagonal member fixing bracket 17 having the above and 43.

At this time, the position of the upper surface of the roof surface 4 having the solar cell panel 91 is higher than that of the roof surface 4 having no solar cell panel 91. The diagonal member fixing bracket 17 is used in which the receiving surfaces 42 and 43 are lowered and the receiving surfaces 42 and 43 on the side of the roof surface 4 having no solar cell panel 91 are raised. For example, in FIG. 8, one receiving surface 42 on the side not having the solar cell panel 91 is high, and the other receiving surface 43 on the side having the solar cell panel 91 is low. Further, in FIG. 13A, one receiving surface 42 on the side having the solar cell panel 91 is low, and the other receiving surface 43 on the side not having the solar cell panel 91 is high.

If the adjacent roof surfaces 4 are the roof surfaces 4 having the solar cell panel 91 or the roof surfaces 4 having no solar cell panel 91, the upper surface of the inclined roof surface 4 as a whole. In order to make the heights uniform, it is preferable to use the diagonal member fixing bracket 17 having two receiving surfaces 42, 43 having the same height, as shown in FIGS. 13B and 13C.

At this time, when the roof surfaces 4 having the solar cell panels 91 are adjacent to each other, the diagonal member fixing bracket 17 (FIG. 13B) in which the receiving surfaces 42 and 43 are both lowered is used. Further, when the roof surfaces 4 having no solar cell panel 91 are adjacent to each other, the diagonal member fixing bracket 17 (FIG. 13C) in which the receiving surfaces 42 and 43 are both raised is used.

Then, as shown in FIG. 14, the roof surface 4 to which the solar cell panel 91 is attached has a base steel plate 85 installed on the roofing material 72 in place of the roof material 73 of FIG. 11, and the sun is attached to the base steel plate 85. The battery mounting bracket is attached, and the solar cell panel 91 is attached using the solar cell mounting bracket. Further, in the case of FIG. 11, the diagonal member fixing bracket 16 having the diagonal member receiving portion 32 having a high receiving surface is used, whereas in the case of FIG. 14, the diagonal member having a low receiving surface is used. The diagonal member fixing bracket 16 provided with the receiving portion 32 is used.

It is preferable that the other configurations of the roof surface 4 are basically the same as those in FIG. The solar cell panel 91 can be preliminarily incorporated into the roof panels 7 and 8 at a factory or the like.

In this way, by properly using a plurality of types of diagonal member fixing brackets 15 to 17 having receiving surfaces 42 and 43 of various heights according to the thickness and configuration of the roof surface 4, the four inclined roof surfaces 4 can be obtained. , It is possible to make the height of the upper surface uniform and install it in a good-looking manner.

(1-7) A building 1 having a roof 2 using the diagonal lumber fixing brackets 15 to 17 is constructed. Hereinafter, the building 1 having the roof 2 using the diagonal lumber fixing brackets 15 to 17 will be described.

As shown in FIG. 1, the building 1 can be a unit building, another building, or the like. For the unit building, the building 1 (or building structure 12) is constructed in a short period of time by transporting the (almost rectangular) building unit 95 manufactured in advance at the factory to the construction site and assembling at the construction site. It is something that can be done. The building unit 95 includes a steel-framed one and a wood-based one, but in this embodiment, it is a steel-framed one.

As shown in FIG. 3, in the steel-framed building unit 95, the upper ends of the four columns (columns 61) are connected in a rectangular shape by four ceiling beams (beam portions 18), and the four columns are connected. It is assumed to have a frame (unit frame) of a box rigid frame structure in which the lower ends are connected in a rectangular shape by four floor beams. The building 1 is not limited to a steel-framed unit building, but may be a wood-based unit building or another building 1.

Then, in the case of a steel-framed unit building, for example, three large building units 95a and three small building units 95b are used to form a building structure 12 (upper floor portion) having a rectangular shape in a plan view. You can do it. Alternatively, the building structure 12 (upper floor portion) may be a structure using an eaves extension eaves beam (beam member 18b) as shown in FIG. 7B instead of the small building unit 95b.

Further, a roof structure 13 is installed in the central portion of the building structure 12 (upper floor portion) in order to install a horizontal roof surface 3 or the like. For example, the roof structure 13 can be a gate-shaped frame (koyagumi portion) in which the four pillar portions 13a and the upper ends of the four pillar portions 13a are connected in a rectangular shape by beams 13b. ..

Then, between the upper part of the roof structure 13 (pillar part 13a) and the upper part (beam part 18) of the building structure 12 (upper floor part), a triangular roof panel 7 or a square roof panel 7 is formed.
