Description

INDUSTRIAL APPLICABILITY The present invention uses a frame member support metal fitting for supporting another frame member such as a cantilever beam having an end surface on the base side joined to a side surface of one frame member such as an outer peripheral beam, and the frame member support metal fitting. The present invention relates to a method for supporting a frame member and a wooden building.

As a frame member support metal fitting, for example, there is a cantilever beam support metal fitting (see, for example, Patent Document 1) that supports a cantilever beam in which the end face on the base side is joined to the side surface of the outer peripheral beam. With this cantilever beam support hardware, when the cantilever beam is joined to the outer peripheral beam of a wooden building to form the floor beam of a balcony or veranda, the cantilever beam is fixed to the side surface of the outer peripheral beam in a cantilevered state. It has a flange that contacts the side surface of the outer peripheral beam and an insertion part into which the base of the cantilever arm is inserted. It consists of a plate and a side plate that connects the lower plate and the upper plate, and the lower plate is cut out across the width to form a window that exposes the lower surface of the arm.

Japanese Patent No. 5415241

However, in the cantilever beam supporting hardware disclosed in the above-mentioned Patent Document 1, the cross-sectional shape of the insertion portion must match the cross-sectional shape of the arm that is the cantilever beam. However, it is necessary to prepare a cantilever support metal fitting having an insertion portion with a different cross-sectional size, which causes problems such as an increase in cost.

Therefore, it is conceivable to support the cantilever beam by fixing L-shaped angle members as cantilever beam support metal fittings on the side surface of the outer beam and the lower surface of the cantilever beam, respectively. After fixing to the side surface, the L-shaped angle member is fixed to the side surface of the outer peripheral beam and the lower surface of the cantilever beam as a cantilever support metal fitting. There may be gaps between them. If a load is applied to the cantilever when a gap is generated between the side surface of the outer peripheral beam and the cantilever support hardware, the tip side of the cantilever will be lowered and the balcony will be greatly tilted. There was a risk that the lower end of the base of the cantilever might sink into the outer peripheral beam or that the initial rigidity would be significantly reduced due to the gap that was created.

Therefore, the present invention has been made focusing on such problems, and can be used regardless of the cross-sectional size of another frame member joined to one frame member, and can be used for one frame member.

Hereinafter, the frame member support hardware, the method for connecting the frame member support hardware using the framework member support hardware, and the wooden building using the framework member support hardware according to the embodiments of the present invention will be described in detail with reference to the drawings. explain. In the embodiment described below, one frame member is a peripheral beam, the other frame member is a cantilever beam, and the frame member supporting hardware according to the present invention is used as the cantilever beam hardware. However, the embodiments described below are merely examples of the present invention including their shapes and dimensions, and the present invention is not limited to the embodiments described below.

<Structure of frame member support hardware 1 of the embodiment>
As shown in FIG. 1 and the like, a framework member supporting metal fitting 1 according to an embodiment of the present invention is a piece that is another framework member in which the end surface on the base side is joined to the side surface of an outer peripheral beam 2 that is one framework member. A plate member 11 and an angle member 12, which are independent members as shown in FIG. 11 and the angle member 12 to the outer peripheral beam 2 and the cantilever beam 3, respectively. It is composed of a gathering screw 15 and the like. In this embodiment, the same long screws are used as the hardware fixing screws 13, the temporary fixing screws 14, and the drawing screws 15, but different screws or screws may of course be used. In FIG. 1, S denotes a room for inserting a beam receiving metal fitting 41 or the like for fixing the beam 4 in the room, which is another frame member, to the outer peripheral beam 2 as shown in FIG. Although not shown in FIG. 1, a similar slit S is also provided in the cantilever beam 3 as a slit provided in the inner beam 4 .

(Plate member 11)
The plate member 11 is a plate-like member fixed to the side surface of the outer beam 2 of the wooden building as shown in FIG. It is made of a thick rectangular steel plate, and has a concave portion 11a in which a convex portion 12a1 (described later) of the angle member 12 is fitted.

Here, the width W1 of the concave portion 11a is the same as the width W3 of the slit S of the cantilever beam 3 (see FIG. 9(b)), for example, 41 mm. The reason why the width W1 of the concave portion 11a is the same as the width W3 of the slit S of the cantilever beam 3 (see FIG. 9B) is that when the plate member 11 is fixed to the outer peripheral beam 2, the width of the plate member 11 is This is because by aligning the recess 11a with the slit S of the cantilever beam 3, positioning when fixing the plate member 11 is facilitated.

On both left and right sides of the recessed portion 11a of the plate member 11, there are round-hole-shaped metal fitting screws as fastener through-holes into which the metal fitting screws 13 for fixing the plate member 11 to the outer peripheral beam 2 are inserted. A total of six through-holes 11b are provided, three each. Here, since the metal fixing screw 13 uses a long screw having a shaft diameter of, for example, 6.3 mm as described later, the hole diameter (inner diameter) of the metal fixing screw through hole 11b is also set to 6.3 mm.

Further, on both left and right sides of the concave portion 11a of the plate member 11, drawing screws 15 are provided for drawing and fixing a later-described plate member facing plate portion 12b of the angle member 12 with respect to the plate member 11 fixed to the outer peripheral beam 2. Two elongated attracting screw insertion holes 11c are provided, each of which is an attracting tool through-hole into which is inserted.

Here, the reason why the drawing screw slot 11c is shaped like an elongated hole is that when the plate member 11 is fixed to the outer peripheral beam 2, the round hole-shaped hardware fixing screw through which the hardware fixing screw 13 is inserted is inserted. This is in order not to be mistaken for the hole 11b and to absorb some vertical displacement during installation.

(Angle member 12)
As shown in FIGS. 5 to 8, the angle member 12 is made of a steel plate having a thickness of about 4 mm to 5 mm like the plate member 11, and is fixed to the lower surface of the cantilever beam 3. and a cantilever beam fixing plate portion 12a made of a steel plate having a thickness of about 9 mm, for example, which is thicker than the plate member 11 and the cantilever beam fixing plate portion 12a so as to face the plate member 11. The plate member opposing plate portion 12b provided on the lower surface and the plate member 11 and the cantilever fixing plate portion 12a are made of a steel plate having a thickness of about 4 mm to 5 mm, and the cantilever fixing plate portion 12a and the plate member It is a member provided with a reinforcing plate portion 12c joined to the opposing plate portion 12b. Incidentally, the reinforcing plate portion 12c is optional and may be omitted.

The cantilever fixing plate portion 12a is provided with a convex portion 12a1 that fits into the concave portion 11a of the plate member 11 and guides the pull of the angle member 12 toward the plate member 11. As shown in FIG. Therefore, the width W2 of the protrusion 12a1 is about 40 mm, which is slightly narrower than the width W1 of the recess 11a of the plate member 11, which is 41 mm.

Further, the cantilever beam fixing plate portion 12a is provided with at least the longitudinal direction of the cantilever beam 3 and the parallel direction so that the angle member 12 can be drawn toward the plate member 11 after the angle member 12 is temporarily fixed to the lower surface of the cantilever beam 3. A temporary fixing screw loose hole 12a2 into which the temporary fixing screw 14 is inserted is provided.

Here, the length L1 (see FIG. 6A) of the straight portion in the longitudinal direction of the temporary fixing screw loose hole 12a2 is, for example, 10 mm, and the temporary fixing screw 14 has a shaft diameter of, for example, 6.3 mm. In order to use a long screw, by providing a semicircular portion with a radius of 3.15 mm at each end of the straight portion in the longitudinal direction of the temporary fixing screw loose hole 12a2, the temporary fixing screw loose hole 12a2 A maximum sliding amount of about 10 mm, which is the maximum pulling amount of the temporary fixing screw 14, is ensured. Therefore, for example, when the temporary fixing screw 14 is inserted into the center of the longitudinal direction of the temporary fixing screw loose hole 12a2 with such dimensions to temporarily fix the angle member 12 to the cantilever beam 3, the angle member 12 is pulled. The shift amount is 5 mm.

Further, the cantilever beam fixing plate portion 12a serves as a fastener through-hole into which a hardware fixing screw 13 is inserted for permanently fixing the angle member 12 to the lower surface of the cantilever beam 3 after the angle member 12 is drawn. Nine round-shaped hardware fixing screw holes 12a3 are provided. Here, since a long screw having the same shaft diameter as the temporary fixing screw 14, for example, 6.3 mm is used as the metal fixing screw 13, the hole diameter (inner diameter) of the metal fixing screw through hole 12a3 The hole diameter (inner diameter) of the screw hole 11b is 6.3 mm.

On the other hand, in the plate member facing plate portion 12b, drawing screws 15 are passed through holes corresponding to the two drawing screw insertion holes 11c of the plate member 11, respectively. A screw through hole 12b1 is provided. The hole diameter (inner diameter) of the drawing screw hole 12b1 is 6.3 mm, the same as the hole diameter (inner diameter) of the hardware fixing screw hole 11b.

The reinforcing plate portion 12c is a member that is joined to the lower surface of the cantilever fixing plate portion 12a and the side surface of the plate member facing plate portion 12b, and has two pulling screws corresponding to the two pulling screw holes 11c. are provided above the screw through holes 12b1.

(Hardware fixing screw 13, temporary fixing screw 14 and drawing screw 15)
The hardware fixing screw 13, the temporary fixing screw 14, and the pulling screw 15 are common long screws having a shaft diameter of, for example, 6.3 mm, a shaft length of, for example, 85 mm, and a screw portion of about 60 mm. use. Of course, different screws or screws may be used as the hardware fixing screw 13, the temporary fixing screw 14, and the drawing screw 15. FIG.

<Usage Example of Frame Material Support Hardware 1 of Embodiment According to the Present Invention>
Next, as an example of use of the framework member support hardware 1 of the embodiment according to the present invention, the cantilever beam 3 joined to the outer peripheral beam 2 is supported by the framework member support hardware 1 of the embodiment, and the outer peripheral beam 2 9 to 17, an example of installing a sweep-out type balcony by attaching floor plywood 5 to the upper surfaces of cantilever beams 3 and in-room beams 4 with floor plywood fixing screws 16 will be described with reference to FIGS. .

(State in which the cantilever beam 3 is joined to the outer peripheral beam 2)
As shown in FIGS. 9(a) and 9(b), the beams 4 in the room are joined to the interior side of the outer peripheral beams 2 of the building via well-known beam receiving hardware 41 and drift pins 42 as fixing pins. In addition, the cantilever beam 3 is joined to the balcony side (outdoor side) of the outer peripheral beam 2 via well-known beam receiving hardware 31 and drift pins 32 and the like. At that time, the beam receiving hardware 31 is attached in advance to the outer peripheral beam 2 by means of bolts 33 and nuts 34 (see FIG. 10), etc., as shown in FIGS. It is attached in advance to the outer peripheral beam 2 with a nut 34 (see FIG. 10) or the like. The illustration of the bolt 33 and the nut 34 is omitted in FIG. 9(a), while the illustration of the drift pin 32 is omitted in FIG. 9(b). etc. are shown or not shown as appropriate.

(Mounting of plate member 11)
Next, as shown in FIGS. 11(a) and 11(b), the plate member 11 constituting the beam receiving support hardware 1 of the embodiment is attached to the lower surface of the cantilever beam 3 at the junction between the outer peripheral beam 2 and the cantilever beam 3, as shown in FIGS. Then, metal fitting screws 13 as fixtures are passed through six metal fitting fixing screw holes 11b (see FIG. 4(b), etc.) of the plate member 11 and fixed.

At this time, as shown in FIGS. 11A and 11B, the upper end of the plate member 11 contacts the lower surface of the cantilever beam 3, and both sides of the recessed portion 11a of the plate member 11 are aligned with the slits of the cantilever beam 3. After being positioned so as to match S, the plate member 11 is fixed to the side surface of the outer peripheral beam 2 with long screws. When the plate member 11 is installed with both sides of the recessed portion 11a of the plate member 11 aligned with the slit S of the cantilever beam 3, the width W1 (see FIG. 4B) of the recessed portion 11a of the plate member 11 can be offset. Since the width W3 (see FIG. 9B) of the slit S of the beam 3 is the same as the width W3 (see FIG. 9B), the center of the lateral direction (width direction) of the cantilever beam 3 and the center of the plate member 11 in the longitudinal direction are The plate member 11 can be installed with sure matching.

(Temporary attachment of angle member 12)
Next, as shown in FIGS. 12 and 13, the angle member 12 is opposed to the plate member 11 so that the plate member facing plate portion 12b is close to the plate member 11, and the cantilever beam fixing plate portion 12a is temporarily fixed with a loose screw. Temporarily fixed to the lower surface of the cantilever beam 3 through the temporary fixing screw 14 through the hole 12a2.

At this time, since the angle member 12 is later drawn toward the plate member 11 fixed to the outer peripheral beam 2 by the drawing screw 15, a slight gap C ( See FIG. 12(b)) does not pose a problem. Thereby, the angle member 12 can be easily temporarily fixed to the lower surface of the cantilever beam 3 .

Further, in order to draw the pull-up screw 15 through the angle member 12 and the plate member 11, the two pull-up screw slotted holes 11c (see FIG. 4(b), etc.) of the plate member 11 and the outer periphery Positioning is performed using the convex portion 12a1 and the concave portion 11a so that the positions of the two drawing screw holes 12b1 (see FIG. 7B, etc.) of the beam fixing plate member facing plate portion 12b are opposed to each other. The angle member 12 is temporarily fixed to the lower surface of the cantilever beam 3.

Furthermore, in order to secure the pull length of the angle member 12 toward the plate member 11, as shown in FIGS. It is inserted near the center in the longitudinal direction and fixed.

(Pulling of angle member 12)
When the temporary fixation of the angle member 12 to the lower surface of the cantilever beam 3 by the temporary fixation screws 14 is completed, then, as shown in FIGS. The pull-up screws 15 are inserted through the through holes 12b1 (see FIG. 7(b), etc.) and rotated to move the angle member 12 toward the plate member 11 fixed to the outer peripheral beam 2. The angle member 12 is drawn toward the plate member 11 so that the gap C (see FIG. 12(b)) between the member 12 and the plate member facing plate portion 12b is minimized. In this embodiment, since the head portion of the hardware fixing screw 13 that fixes the plate member 11 to the outer peripheral beam 2 protrudes from the plate member 11, as shown in FIG. The angle member 12 is pulled toward the plate member 11 until the plate portion 12b abuts the head portion of the screw 13 for fixing the hardware.

By pulling the angle member 12, the position of the temporary fixing screw 14 in the temporary fixing screw loose hole 12a2 is shifted in the longitudinal direction of the temporary fixing screw loose hole 12a2 as shown in FIGS. From the vicinity of the center, as shown in FIGS. 15(b) and 15(c), it is shifted to the right in the drawing from the longitudinal center of the temporary fixing screw loose hole 12a2.

(Main fixation of angle member 12)
When the angle member 12 is completely drawn toward the plate member 11 by the drawing screw 15, the nine metal fixing screw holes of the angle member 12 are opened as shown in FIGS. The angle member 12 is fixed to the lower surface of the cantilever beam 3 by passing the hardware fixing screw 13 through 12a3 (see FIGS. 6A, 7A, etc.). This completes the attachment of the framework member support hardware 1 of the embodiment.

(Installation of floor plywood 5)
After the angle member 12 is fixed, for example, as shown in FIG.

<Summary of framework member support hardware 1 according to the embodiment of the present invention>
As described above, the framework member support hardware 1 according to the embodiment of the present invention includes the plate member 11 fixed to the side surface of the outer peripheral beam 2 and the cantilever beam fixing plate portion fixed to the lower surface of the cantilever beam 3. 12a and an angle member 12 having a plate member facing plate portion 12b provided so as to face the plate member 11, and a temporary fixing screw 14 is inserted into the cantilever fixing plate portion 12a of the angle member 12. Temporarily fixing the angle member 12 to the cantilever beam 3 by temporarily fixing the angle member 12 to the cantilever beam 3 and pulling the angle member 12 toward the outer peripheral beam 2 after temporary fixing by play in the direction parallel to the longitudinal direction of the cantilever beam 3 at least. While the screw through loose holes 12a2 are provided, pulling screws 15 for pulling the angle member 12 toward the plate member are inserted into the opposed portions of the plate member facing plate portion 12b of the plate member 11 and the angle member 12, respectively. An elongated hole 11c for inserting screws and an elongated hole 12b1 for inserting screws are provided.

Therefore, unlike the technique of the above-described conventional patent document 1, the framework member supporting hardware 1 is divided into a plate member 11 and an angle member 12, and the cantilever beam fixing plate portion 12a of the angle member 12 is fixed to one side. Since the cantilever beam 3 is supported by being fixed to the lower surface of the cantilever beam 3, it can be used regardless of the cross-sectional size of the cantilever beam 3, and the cost can be reduced.

In addition, in the framework member support hardware 1 of the embodiment according to the present invention, the angle member 12 is attached by inserting the temporary fixing screw 14 into the temporary fixing screw loose hole 12a2 of the cantilever fixing plate portion 12a of the angle member 12. is temporarily fixed to the cantilever beam 3, a gap C (Fig. 12 ( b)), the plate member 11 fixed to the outer beam 2 and the plate member facing plate portion 12b of the temporarily fixed angle member 12 communicate with the drawing screw slot 11c and the drawing screw. By inserting the pulling screw 15 into the through hole 12b1 and rotating it, the angle member 12 can be pulled toward the plate member 11, and the gap C can be minimized later.

As a result, when a load is applied to the cantilever beam 3, the tip side of the cantilever beam 3 is lowered to prevent the balcony from being greatly inclined. It is possible to reliably prevent problems such as the problem of being embedded in 2 and the problem of a significant reduction in initial rigidity due to gaps.

In addition, in the framework member support hardware 1 according to the present invention, the recess 11 a is provided in the upper portion of the plate member 11 , and the cantilever fixing plate portion 12 a of the angle member 12 is fitted into the recess 11 a of the plate member 11 . A convex portion 12a1 is provided to guide the pulling of the angle member 12 with respect to the plate member 11. As shown in FIG.

Therefore, when the angle member 12 is pulled toward the plate member 11 fixed to the outer peripheral beam 2, the convex portion 12a1 of the angle member 12 is guided by the concave portion 11a of the plate member 11, so that the plate member can be moved in a more reliable and stable state. It becomes possible to pull the angle member 12 against 11 .

In addition, in the framework member support hardware 1 according to the present invention, the connection between the side surface of the outer peripheral beam 2 and the base side end surface of the cantilever beam 3 is performed by the back plate portion fixed to the side surface of the outer peripheral beam 2 and the back plate portion. A beam receiving hardware 31 extending from both left and right sides of the plate portion in a direction perpendicular to the back plate and having a pair of side plate portions formed with pin insertion holes into which drift pins 32 as fixing pins are inserted; After the pair of side plate portions of the beam receiving hardware 31 are inserted into the pair of slits S formed in the base side end face of the cantilever beam 3 and the pair of slits S, drift pins 32 are used to penetrate the pin insertion holes of the cantilever beam 3 and the pair of slits S. The width W1 of the concave portion 11a of the plate member 11 (see FIG. 4B) is approximately the width W3 between the pair of slits S of the cantilever beam 3 (see FIG. 9B). are doing the same.

Therefore, when fixing the plate member 11 to the outer peripheral beam 2, by aligning the recessed portion 11a of the plate member 11 with the slit S of the cantilever beam 3, the plate member 11 can be fixed and positioned. , the plate member 11 can be easily fixed at the optimum position of the outer peripheral beam 2, and workability can be improved.

In addition, in the method of supporting the cantilever beam 3 using the framework member support hardware 1 according to the present invention, the plate member 11 is attached to the side surface of the outer peripheral beam 2 in the vicinity of the joint between the side surface of the outer peripheral beam 2 and the cantilever beam 3. The cantilever beam fixing plate portion 12a of the angle member 12 is fixed to the lower surface of the cantilever beam 3 in the vicinity of the joint portion between the side surface of the outer peripheral beam 2 and the cantilever beam 3. Temporary fixing screws 14 are used to temporarily fix the loose holes 12a2, and then pull screws 15 are passed through the fixing tool holes 11c and 12b1 of the plate member opposing plate portions 12b of the plate member 11 and the angle member 12, respectively. The drawing screw 15 is tightened until the plate member facing plate portion 12b abuts the plate member 11 or the head of the hardware fixing screw 13 fixing the plate member 11 to the side surface of the outer peripheral beam 2, and the temporary fixing screw is threaded. The angle member 12 is attracted to the plate member 11 by the play of the loose hole 12a2, and after that, the metal fitting fixing screw 13 is passed through the metal fitting fixing screw hole 12a3 of the cantilever beam fixing plate portion 12a of the angle member 12 and cantilevered. The angle member 12 is fixed to the beam 3.

Therefore, even if a gap C (see FIG. 12(b)) is generated between the plate member 11 fixed to the outer peripheral beam 2 and the plate member facing plate portion 12b of the angle member 12 temporarily fixed to the cantilever beam 3. After temporarily fixing the angle member 12 to the cantilever beam 3 by inserting the temporary fixing screw 14 into the temporary fixing screw loose hole 12a2 of the cantilever fixing plate portion 12a of the angle member 12, the angle member 12 is fixed to the outer peripheral beam 2. Pulling screws 15 are inserted into pulling screw holes 12b1 and pulling screw insertion holes 11c and 12b1, which communicate with the plate member facing plate portion 12b of the temporarily fixed plate member 11 and the temporarily fixed angle member 12. can be pulled toward the plate member 11 and the gap C can be minimized later, so the balcony is made large so that the tip side of the cantilever beam 3 is lowered when a load is applied to the cantilever beam 3. Inclination can be suppressed, and problems such as the lower end of the base of the cantilever beam 3 sinking into the outer peripheral beam 2 and the problem that the initial rigidity significantly decreases due to the gap can be reliably prevented. In addition, since the mechanism is such that the hardware such as the angle member 12 moves when the temporary fixing screw loose hole 12a2 is drawn, the load on the cantilever beam 3 is reduced, and splitting of the wood can be prevented.

In addition, in the wooden building according to the embodiment of the present invention, the above-described framework member support hardware 1 composed of the plate member 11, the angle member 12, etc. is used to attach the base to the outdoor side (balcony side) side of the outer peripheral beam 2. As shown in FIG. The floor plywood 5 is attached by a floor plywood fixing screw 16. - 特許庁

Therefore, the load applied to the cantilever beam 3 can be borne not only by the frame member supporting metal fittings 1 but also by the floor plywood 5, so that it is possible to further prevent the cantilever beam 3 from being tilted or pinched. .

In the above-described embodiment, one frame member is the outer peripheral beam 2, the other frame member is the cantilever beam 3, and the frame member support hardware 1 according to the present invention is a cantilever joined to the outer peripheral beam 2. Although the cantilever beam support hardware for supporting the beams 3 has been described, the present invention is not limited to this, and other frame members may be used at the joints of the portal frame, the joints of the capitals and the pedestals, and the like. Of course, it may also be used as a frame member supporting hardware for supporting the frame member.
