Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a projecting corner frame structure in a hipped structure of a wooden building.

In the conventional hipped building, the projecting corner frame structure involves joining the eaves that are orthogonal to each other in a cross shape using intersecting interlocking, and then creating a notch at the corner wood at the construction site to match the width and slope of the corner wood. The drawback was that it required a high degree of skill acquisition and a long time for processing.

On the other hand, the applicant standardized the structure of each part of the frame structure of wooden buildings in general, and processed all the joints, wood ends, joints, etc. intensively using machines in the factory, and at the construction site, these The present invention has already proposed new inventions and ideas related to wooden frame construction methods that allow high-quality wooden buildings to be easily assembled by simply joining processed parts using joining fittings. It is related to inventions and ideas.

The object of the present invention is to be able to be used in combination with the above novel inventions and ideas, and to solve the above-mentioned drawbacks.
To provide a frame structure with protruding corners capable of suppressing wastage of wood, significantly shortening working time at a construction site, and allowing easy marking of processed parts using a gauge.

The present invention will be explained below based on drawings of embodiments.

FIG. 1 shows an exploded perspective view showing an example of an eaves joint structure that is the premise of the present invention, and FIG. 2 shows an assembled perspective view thereof.

The end of one girder 2 is joined to the upper end surface of the through column 1, and the end of the other girder 4 is joined to the end of the inner surface 3 of the girder 2, thereby forming a protruding corner. The end face of the girder 4 has both left and right sides cut into a rectangular shape from the upper edge to the lower edge to form both left and right concave parts, and the remaining part in the center is used as a central convex part 5. On the other hand, a recess 6 is formed at the end of the side surface 3 of the girder 2 to fit into the central projection 5, and when the central projection 5 and the recess 6 are fitted together, both the left and right recesses abut against the side surface 3. The outer surface 7 of the spar 4 corresponds to the end surface 8 of the spar 2. Further, dowel holes are formed at the center point of the central convex portion 5 and the center point of the recessed portion 6, respectively, and a common dowel 9 is inserted through both dowel holes. A horizontal cut groove 10 is carved in the end of the girder 4, and reinforcing hardware 11 is inserted from both left and right sides of the cut groove 10.
and 12 are installed.

Among these reinforcing hardware, the one for the outer surface 11 is made by bending one end 111 of a rectangular plate at right angles to the other end of the backing plate 112. It is made integrally by welding or the like along a line, and the backing plate has bolt mounting holes 114, and the penetration plate 113 has pin holes 11.
5 is worn. Further, the width dimension in the vertical direction of this backing plate 112 is smaller than the height of the side surface of the girder 4, and in the installed state, the upper edge 11 of the reinforcing hardware 11
6 and the ridge line 13 at the upper edge of the side surface of the girder 4, a wooden portion having a predetermined width A is exposed. In the example, if the height of the side surface 7 of the girder 4 is 100 mm, the width is 60 mm.
A reinforcing hardware was used, and A = 20 mm.

The reinforcing hardware 12 for the inner surface has its backing plate 122
The one for the outer surface 11 is shorter in length and the direction of bending of one end 121 is different from that for the outer surface.
A penetration plate 123 similar to the above is formed. Bolts 14, 14 fasten reinforcing hardware 11, 12 to girder 4, and pins 15, 15 are driven into pin holes of the penetration plate through pin holes 16, 16 bored in the upper surface of girder 4.

A dowel 17 is planted on the upper end surface 16 of the column 1, and the girder 2
It is inserted through the dowel hole drilled in the lower end of the. Note that shallow central grooves 18 and 19 are formed along the longitudinal direction on the lower surfaces of the beams 2 and 4. This is used when constructing intermediary materials such as lintels and liners, or panel materials such as heat insulation boards, and is also useful for distinguishing between upper and lower surfaces.

All operations such as drilling dowel holes, removing recesses, cutting grooves, and drilling pin holes in this joining device are performed centrally at the factory. The assembly work at the construction site involves joining the girder 2 onto the column 1, joining the end face of the girder 4 to the end of the girder 2, and then inserting the penetration plates of the reinforcing metal fittings 11 and 12 into the cut grooves 10 and attaching the bolts 14. Tighten temporarily. Next, screw the bent parts of the reinforcing hardware 11 and 12 onto the girder 2,
It is fixed with bolts, etc., and then pins 15, 15 are driven in. In addition, if the position of the pin hole of the girder 4 is set eccentrically in the direction far from the end surface of the butt end than the position of the pin hole of the penetration plate, within the limit of the pin radius, the end of the girder 4 will be aligned with the girder by driving the pin. 2 is strongly pressed and the joint structure is tightened. After driving the pins 15, 15, the temporarily tightened bolts 14, 14 are strongly tightened to complete the assembly work.

In such a projecting corner frame of an eave girder, the upper edge 1 of the reinforcing hardware 11 is the part on which the corner beam is to be placed.
16 and above the surface that is inclined at a predetermined slope is cut away to form a cut away part as shown in FIG. That is, triangular vertical surfaces 21 and 21 facing each other into which the width of the corner piece fits, a left inclined surface 22 and a right inclined surface 23 that are bisected with the axis of the corner wood as a border, are formed, and the upper edges 2 of the left and right inclined surfaces 22 and 23 are formed.
4 and 25 are parallel to the outer surfaces of the beams 2 and 4, respectively, and are perpendicular to each other.

The corner piece to be placed on this cut away portion has a cross-sectional shape as shown in FIG. That is, the bottom surface of the corner block 26 is the upper edge 116,1 of the reinforcing hardware 11
16, both left and right edges 261, 262
An F-shaped groove is formed by two sides 263 and 264 that become deeper toward the center, and shelf portions 265 and 26 are formed by cutting and removing the upper portions of both left and right sides.
6 is formed.

Left and right inclined surfaces 22 and 23 of the above-mentioned cut-off portion
Dowels (not shown) planted in the bottom surface 2 of the corner wood 26
Fit the dowel holes drilled in holes 63 and 264, attach the corner block 26 as shown in Figure 5, drive the nails 27 through the shelf of the corner block, and place the rafters 28 on the shelf and girder. The projecting corner frame of the hipped building is completed.

FIG. 6 shows a perspective view of a ruler useful for carrying out the invention. This ruler 30 is used to mark the area to be cut and removed by applying it to the orthogonal part of the girder shown in FIG. This ruler consists of two perpendicular surfaces 301, 302 and a horizontal surface 303, which are perpendicular to each other.
The horizontal surface 303 is provided with contour lines or mark holes that define the lengths B ₁ , B ₂ , and B ₃ from the inner surfaces of the two vertical surfaces 301 and 302, respectively. _B1 ,
B ₂ and B ₃ correspond to, for example, each slope of 30/100, 35/100, and 40/100, and using this ruler, both the left and right sides 21, 21 and the upper edge line 24, 25 can be marked immediately.

FIG. 7 shows an exploded perspective view of another embodiment of the joint structure of the projecting corner portion of the eave sill according to the present invention. This embodiment differs from the previous one in that eaves beams 34, 35 are attached to the upper ends 32, 33 of two adjacent sides of the column 31.
The end faces of the eave girders 34 and 35 are joined by fitting the uneven parts and dowels, and cut grooves 3 are formed at the ends of each of the eave girders 34 and 35.
6 and 36, and L-shaped reinforcing metal fittings 37 and 38 with penetration plates at both ends are used to form a joint at the protruding corner. Therefore, the corner block is mainly mounted directly on the upper end of the column 31.

FIG. 8 shows a perspective view of another embodiment of the cut-and-remove portion for mounting a corner block according to the present invention. The difference between this embodiment and the above-mentioned one is that the inclined surface 41 on which the corner board rests does not have a ridge line that bisects the left and right sides and is a single plane, whereas the corner board is attached to the outer surface of the protruding corner. The upper edge 43 of the reinforcing hardware 42 is the apex 44
The slope becomes lower as it gets closer to . Therefore, a corner block with a flat bottom can be used.

According to the present invention, the width dimension of the exposed wood part from the upper edge of the eave girder to the upper edge of the reinforcing hardware is determined by the standardized frame structure, and the width dimension of the exposed wood part from the upper edge of the eave girder to the upper edge of the reinforcing hardware is determined, and the width dimension is determined by a specified distance from the outer ridgeline of the eave girder. A predetermined slope can be obtained by simply drawing a score line inwardly and using this as the upper edge of the slope. In addition, compared to conventional construction methods, the volume of the part to be removed to place the corner wood is small, and the working time is significantly shortened. In particular, when the bottom of the corner wood is made into an F-shape, the amount of part to be cut and removed is further reduced.

Furthermore, when shelves are provided on both left and right sides of the corner wood, it becomes easier to attach the rafters and nail the corner wood.
