Description

  The present invention relates to a structural joint hardware, and more particularly to a structural joint hardware suitable as a hole-down hardware used for joining a base and a column, a beam and a column, or the like.

In general, in a wooden house, as shown in FIG. 18, a horizontal member, that is, a base 2 is placed on a foundation 1 such as concrete, and a pillar 3 is vertically attached on the base 2. Yes.
In such a wooden house, for example, when a strong direct earthquake occurs, a strong pulling force is exerted on the pillar 3, and there is a possibility that the pillar without the tenon breaks and the building collapses. Therefore, conventionally, the bonding strength of the foundation 1, the base 2 and the column 3 is increased by using a structural bonding hardware, for example, a hole-down hardware 4, so as to withstand this pulling force.

  Specifically, as shown in FIG. 18, the head 5 a of the anchor bolt 5 that penetrates the base 2 from the foundation 1 and fastens them together is inserted into the hole of the locking surface 4 a below the hole-down hardware 4. Fasten with nut 6. Further, the side plate 4 b of the hole-down hardware 4 is fixed to the side surface of the pillar 3 by a plurality of, for example, three bolts 7.

By the way, in the above-mentioned wooden house, a structure that can withstand the above-described pulling force is required, and at the same time, it is necessary to improve the rigidity in the horizontal direction such as a roll in the event of an earthquake. Therefore, conventionally, it has been common to insert a brace (not shown) between the pillar 3 and an adjacent stud (not shown).
However, recently, instead of the brace described above, a so-called panel method has been proposed in which the panel 8 is fitted over the entire surface between the columns to further increase the lateral rigidity. However, when such a panel structure is employed, the degree of freedom of workability of the panel 8 is significantly reduced because the above-described hole-down hardware 4, in particular, the locking surface 4 a protrudes from the side surface of the column 3. Problems arise.

  An object of the present invention is to solve the above-described problems and to provide a structural joint metal having a function that can sufficiently withstand an upward pulling force and that does not protrude from a side surface of a column.

  As a result of various investigations to achieve the above-mentioned object, the inventors of the present invention do not fix the structural joint hardware to one side of the column as in the prior art, but use a flat member to oppose the column. The idea was that the two side surfaces to be sandwiched and fixed to these side surfaces would not protrude from the side surfaces. Furthermore, by forming a space for accommodating a bolt head and a nut for joining the horizontal member and the hardware at the lower part of the joint hardware, a structure in which bolts, nuts, etc. do not protrude from the side surfaces of the columns in the same manner. did.

  That is, according to the present invention, there is a structural joint hardware for fixing a column to a horizontal member, on a rectangular substrate portion and side surfaces of the column attached from two opposite sides of the substrate portion. And a hardware main body comprising a side plate portion sandwiching the pillar and a holding portion for holding the mounting surface of the pillar at a predetermined height from the substrate portion. Each side plate portion is provided with a fastening hole for joining to the column, and the substrate portion is provided with a bolt hole for joining to the horizontal member.

Further, a guide for a tenon hole may be fixed to protrude downward on the lower surface of the substrate portion of the hardware body, and a brace plate may be attached to at least one of the side plate portions of the hardware body. .
Furthermore, in order to be able to cope with the case where the mounting position of the anchor bolt is not accurate, the anchor bolt mounting hole in the base part of the structural joint hardware is at least in the notch direction of the guide for the tenon hole and the direction perpendicular to the notch direction, The bolt hole diameter may be sufficiently large, and a washer that is sufficiently larger than the hole may be fixed by being sandwiched between the bolt or nut and the structural joint base. Further, when the displacement of the anchor bolt mounting position is in the direction opposite to the notch direction of the guide hole guide, this can be dealt with by changing the direction of the entire structural joint metal by 180 °.

  In the case of using a fastening member (such as a bolt and a nut) that inserts the joint between the pillar and the structural metal fitting into the fastening hole of each side plate that sandwiches the pillar and fixes the pillar to the side plate. In order to prevent cracking caused by moving downward with respect to the pillar while the tensile stress acts on the side plate portion and the fastening member fixed to the side plate portion bites into the wood of the pillar, a rod-like member that contacts perpendicularly to the bolt ( For example, a drift pin is penetrated, and the stress acting on the column in a straight line immediately below the fastening member from the fastening member is also distributed to the lower side of the rod-like member, so that the column and the structural joint as a whole It is also possible to increase the tensile strength of the joint.

  As described above, the structural joint hardware of the present invention has sufficient strength to withstand a strong pulling force when the column and the horizontal member are joined, and at the same time, there is no portion protruding from the side surface of the column. The panel construction method has the advantage that the degree of freedom of workability increases. Therefore, its industrial value is extremely large.

The box-type hole-down hardware of the present invention will be described in detail below with reference to the accompanying drawings.
1-3 is an example of the structure of the hole-down hardware which is one Embodiment of the structural metal fitting of this invention, The positional relationship with the pillar 14 and horizontal member (base) 15 to which this hole-down hardware 10 is attached. Is shown at the same time.
That is, the hole-down hardware 10 is bent into a substantially U-shaped cross section, and is a box-shaped hardware body 11 composed of a substrate portion 11a and side plate portions 11b and 11c, and a predetermined height from the substrate portion 11a of the body 11. And a receiving plate 12 to be locked. The receiving plate 12 has a function of holding a mounting surface 14 a of the pillar 14 and forming a space for accommodating a bolt head described later between the metal plate 11 and the substrate portion 11 a. Bolt holes 11d are formed in the base plate portion 11a of the hardware body 11 for inserting bolt heads, which will be described later.

The opposing side plate portions 11b and 11c of the hardware main body 11 are reduced in width at a predetermined height from the substrate portion 11a, i.e., the locking position of the receiving plate 12, and a shoulder portion 11e for locking the receiving plate 12. 11f are formed. Accordingly, the width of the reduced width portion is smaller than the width of the side surfaces 14b and 14c of the column 14.
In addition, fastening holes for fixing the hole-down hardware 10 to the side surfaces 14b and 14c of the pillar 14 are formed in the side plate portions 11b and 11c. The fastening hole specifically refers to a bolt hole, a screw hole, or the like. FIG. 1 shows an example in which one bolt hole 11k is formed above each of the side plate portions 11b and 11c, and a plurality of, that is, eight screw holes 11g are formed therebelow.

  As shown in FIG. 1, the reason why the four sets of screw holes 11g arranged on the left and right of the center line of the side plate surface are arranged asymmetrically with respect to the center line is that the two opposing side plates This is because the screw holes 11g of the portions 11b and 11c are arranged at positions shifted in the vertical direction and / or the horizontal direction to prevent the screws 19 for fixing the pillars 14 from both sides from being overlapped in a straight line (see FIG. 3). . That is, if the screws 19 screwed in from both sides overlap in a straight line, there is a possibility that the pillars 14 may be cracked in the vicinity of the tip portions of both.

In order to fix the column 14 by the metal body 11, any structure such as inserting a bolt (not shown) into the bolt hole 11k, screwing a screw into the screw hole 11g, or using both the bolt and the screw together. It can also be. Moreover, it is preferable that the number and arrangement of screws actually used are appropriately determined according to the strength required for the hole-down hardware 10.
The receiving plate 12 is formed with notches 12a and 12b substantially equal in thickness to the side plate portions 11b and 11c of the hardware main body 11 on two opposite sides, and the receiving plate 12 is dropped from above the hardware main body 11. At this time, the projecting portions 12c and 12d on both sides of the notches 12a and 12b are brought into contact with and engaged with the shoulder portions 11e and 11f on the side surfaces of the main body.

In this way, by arranging the receiving plate 12 at a predetermined height from the substrate portion 11a of the metal body 11, a bolt 16 and a washer (washer) described later are provided between the substrate portion 11a and the mounting surface 14a of the column 14. ) 17, an appropriate space for accommodating the nut 18 and the like (reference S in FIGS. 2 and 3) can be secured.
The receiving plate 12 is formed with a hole 12e for increasing the freedom of the bolt length when the hole-down hardware 10 is attached to the base 15.

  With the receiving plate 12 attached to the hardware main body 11, the bottom surface 14 a of the column 14 is placed on the receiving plate 12, and the side surfaces 14 b and 14 c of the column 14 are sandwiched between the side plate portions 11 b and 11 c facing the hardware main body 11. For example, both are fixed with screws 19. At this time, if the concave portions 14d and 14e corresponding to the size and shape of the reduced width portions of the side plate portions 11b and 11c of the metal body 11 are formed on the side surfaces 14b and 14c of the column 14, the both side plates of the hardware body 11 are formed. The portions 11b and 11c are substantially flush with the side surfaces 14b and 14c of the column 14, and can be structured not to protrude from the side surfaces 14b and 14c of the column 14.

Also, as shown in FIGS. 2 and 3, by setting the depth of the recesses 14d and 14e of the column 14 to be greater than the thickness of the side plate portions, when these side plate portions 11b and 11c are attached, The 19 heads can also be structured not to protrude from the side surfaces 14 b and 14 c of the column 14.
Further, as described above, by fitting the side plate portions 11b and 11c of the hole-down hardware main body 11 into the recesses 14d and 14e of the column 14, in addition to the strength against shaking in the direction orthogonal to the plate surface of the column of the side plate portion. Thus, it is possible to increase the strength of the hardware even when the side plate portion of the column 14 swings in a direction parallel to the plate surface.

  On the other hand, on the lower surface of the substrate portion 11a of the hardware main body 11, when the hole-down hardware 10 is attached to the base 15, an alignment guide (hereinafter referred to as a hozo hole) for fitting into a base hole 15a formed in the base 15 is provided. (Referred to as a guide) 13 is fixed. Specifically, it can be formed by welding a U-shaped member whose both ends are bent to the bottom surface of the metal body 11, and a bolt hole 13 b is formed on the lower surface 13 a of the guide hole guide 13. Has been.

Positioning can easily be performed by fitting the guide hole guide 13 into a horizontal hole, for example, a side hole 15 a formed in the base 15.
In the above configuration, for example, the dimensions x1 to x6 of each part of the hole-down hardware 10 applied to the 105 mm square pillar 14 are preferably determined as follows. That is, in FIG. 1, x1 = 52 mm, x2 = 140.2 mm, x3 = 36.8 mm, x4 = 84 mm, x5 = 30 mm, x6 = 30 mm. Moreover, it is preferable that the thickness of the metal main body 11 and the receiving plate 12 is 3.2 to 4.5 mm, and the thickness of the guide hole 13 is 3.2 to 4.5 mm.

Next, the mounting structure of the hole-down hardware 10 will be described with reference to FIGS. 2 and 3, the same components as those in FIG. 1 are denoted by the same reference numerals.
First, a bolt projecting from the relief hole 15a of the base 15 such as the head 16a of the anchor bolt 16 is inserted into the bolt hole 13b of the guide bottom surface 13a for the relief hole of the hole-down hardware body 11 and the bolt hole 11d of the hardware body substrate portion 11a. The base 15 and the hole-down hardware body 11 are joined by screwing the nut 18 through the washer (washer) 17. After that, the receiving plate 12 is dropped into the hardware main body 11 to be locked at the positions of the base 15 and the shoulder portions 11e and 11f of the hardware main body 11.

  Next, the pillar 14 is placed on the receiving plate 12 of the hole-down hardware 10, and both side plates 11 b and 11 c of the hardware body 11 are fitted into the recesses 14 d and 14 e on the side surface of the pillar 14, and then the required number of screws 19. Are fixed to both side plate portions 11b and 11c of the hardware main body 11, respectively. Note that, instead of the screw 19 or in combination with the screw 19, only the bolt that penetrates the side surfaces 14b and 14c of the column 14 or a combination of a bolt and a nut (both not shown) may be used to fix the hardware body. Good.

The above-described relief hole 15a and the relief hole guide 13 are convenient in that the positioning of the hardware body 10 can be easily performed, but may be omitted depending on circumstances.
In addition, you may fix with the combination (refer FIG. 4) of the volt | bolt (fastening member) 51 and the nut (fastening member) 52 which penetrate the side surfaces 14b and 14c of a pillar, and also in that case, it is below the volt | bolt 51. A drift pin (bar-shaped member) 53 may be inserted so as to be substantially orthogonal to the bolt 51 (FIG. 4).

  It is assumed that a tensile stress acts on the pillar 14 due to an earthquake or the like, and the bolt 51 bites into the wood portion immediately below the pillar 14, thereby causing a crack in the pillar 14. However, the bolt 51 and the drift pin 53 are orthogonal to and in contact with each other. As a result, the force of the wood cracking is distributed to the bolts 51 and the drift pins 53 to prevent the wood cracking, and as a result, the joining strength between the pillars 14, the structural hardware 11 and the pillars 14 is improved.

5 and 6 show another embodiment of the receiving plate 12 and its mounting structure, in which the same components as those in FIGS. 1 to 3 are given the same reference numerals.
The receiving plate 12 shown in FIG. 5 has a hexagonal hole 12f formed in the center, which is formed to be slightly larger than the dimensions of the head 161a of the bolt 161 shown in FIG.
FIG. 6 shows a state in which the column 14 is fixed using the receiving plate 12 of FIG. 5, and the tip of the head 161 a of the bolt 161 is accommodated in the hole 12 f of the receiving plate 12. In this case, since only a slight gap is formed between the head 161a of the bolt 161 and the inner peripheral surface of the hole 12f, there is an effect that the receiving plate 12 has a function of stopping rotation of the bolt 161. . In order to prevent the head 161a of the bolt 161 from coming into contact with the bottom surface of the column 14, a slight space is formed between the bolt head 161a and the bottom surface of the column 14 with respect to the plate thickness of the receiving plate 12. It is preferable to take measures such as increasing the thickness to a certain level or forming a notch for accommodating the bolt head at the bottom of the column 14.

FIGS. 7 and 8 show another embodiment of the hole-down hardware guide hole guide. In the figure, the same components as those in FIG.
7 is integrated by welding the guide hole guide 13 shown in FIG. 1 to the bottom surface 11a of the metal body 11 in the upside down direction. Bolt holes 23 b are formed in the welding surface 23 a of the guide hole guide 23.

8 is integrated by welding a bottomed cylindrical member obtained by, for example, punching a metal plate to the bottom surface of the hardware main body 11 at the upper end opening edge 24a. . Bolt holes 24 c are formed in the bottom surface 24 b of the relief hole guide 24.
As described above, the shape of the guide for the burrow hole is not particularly limited, but as shown in FIGS. 1 and 8, the larger the area in contact with the inner surface of the burrow hole, the higher the strength, which is preferable.

  9 to 11 show another embodiment of the present invention. In the figure, the same components as those in FIG. 1 are denoted by the same reference numerals. In the figure, the receiving plate is omitted. As shown in FIG. 9, the guide hole 29 to be welded to the bottom of the hardware main body 11 shown in FIG. 11 is formed in a rectangular tube shape that contacts each side wall of the side hole 15 a and faces one side wall of the side hole. A part of the side wall is cut to form a C-shaped cross section. Further, the bolt hole 11m of the base portion 11a of the metal body 11 has a shape in which the four corners of the rectangle are trimmed in an arc shape and the approximate center of one long side is cut out in the arc shape 11, so that the guide hole guide 29 The size of the hole is larger than the diameter of the bolt 16 in the notch direction and the direction perpendicular to the notch direction.

  As shown in FIG. 10, the main body 11 and the guide hole guide 29 pass through a guide hole guide 29 that does not restrain the anchor bolt position at the tip of the anchor bolt 16, and a washer (washer) 17 larger than the bolt hole 11 m. Is fixed by tightening with a nut 18 through a fixing bolt hole 11m. At this time, due to the effect of the shape of the bolt hole 11m, the anchor main body 11 can be moved even when the anchor bolt 16 is at a position 16a displaced in the notch direction of the guide hole guide 29 or a position 16b displaced in the vertical direction. Can be fixed without hindrance. Moreover, when it shifts | deviates to the direction opposite to the notch direction of the guide hole guide 29 (16c), it can respond by changing the metal-body main body 11 180 degrees.

  FIG. 12 shows another embodiment of the present invention. In the figure, the same components as those in FIG. 1 are denoted by the same reference numerals. In the drawing, only the hardware main body is shown, and the receiving plate and the guide for the side holes are omitted. The hardware body 11 is obtained by welding reinforcement plates 11h and 11j between the side plate portions 11b and 11c to further increase the strength of the entire hardware.

  In this configuration, between the upper ends of the reinforcing plates 11h and 11j and a receiving plate (not shown), that is, between the upper ends of the reinforcing plates 11h and 11j and the shoulder portions 11e and 11f formed on the hardware body side plate portions 11b and 11c. From the viewpoint of workability, it is preferable to form a gap for inserting a spanner or the like when the nut is screwed onto the bolt. Moreover, it is preferable that the same guide for a hole as shown in FIG.

FIG. 13 shows another embodiment of the hole-down hardware. In FIG. 13, the same components as those in FIG. 1 are denoted by the same reference numerals. Note that the receiving plate is omitted.
The hole-down hardware body 11 is formed by integrally forming a brace plate. In the figure, a brace plate 30 is attached to one side plate portion of the hardware main body 11, for example, 11 c. The brace plate 30 includes an attachment portion 31 and a plate portion 32. The attachment portion 31 is fixed to the main body side plate portion 11c by welding, for example, and a screw hole is provided at a position corresponding to the screw hole 11g of the side plate portion 11c. 31a is formed. The plate portion 32 is formed with a plurality of screw holes 32a for fixing the brace.

FIG. 14 shows a state in which the brace is fixed using the box-type hole-down hardware with brace plate. In the figure, the same components as those in FIG.
In FIG. 14, as in FIG. 2, a pillar 14 is joined to a base 15 via a hole-down hardware body 11. Further, a brace 26 is fixed to a base 25 orthogonal to the base 15 via a plate portion 32. The brace 26 and the plate portion 32 can be fixed by screws 27, for example, but can be fixed by bolts (not shown) instead of screws.

For example, when the outer side of the column 14 (the left side in the drawing) is an outer wall, such a configuration is such that the columns 14 and the columns along the outer wall (columns arranged in a direction perpendicular to the paper surface, not shown) In the meantime, a panel (not shown) is constructed, but since the top 25 becomes an inner wall (not shown), it is not necessary to construct the panel, and it is particularly effective in a situation where a brace is sufficient.
FIG. 15 shows another embodiment of the box-type hole-down hardware of the present invention, which is different from the hole-down hardware 10 shown in FIG. 1 in the shape of the side plate portion and the structure of the locking portion. That is, the hole-down hardware 40 includes a hardware main body 41 having a substantially U-shaped cross section and a locking portion 42 that is also formed in a substantially U-shaped cross-section and is accommodated in the main body.

Similarly to the above, the hardware main body 41 is composed of a substrate portion 41a and opposing side plate portions 41b and 41c, and the locking portion 42 is composed of a receiving plate portion 42a and leg portions 42b and 42c. The widths of the side plate portions 41b and 41c are substantially equal to the width of the column 20 to be attached.
Bolt holes 41d for inserting bolts are formed in the base plate portion 41a of the metal main body 41, and a plurality of screw holes 41e and one piece for fixing the metal main body 41 to the pillar are formed in the side plate portions 41b and 41c. Bolt holes 41f are respectively formed. The leg portions 42b and 42c of the locking portion 42 are welded and fixed to the side surfaces 41b and 41c of the hardware main body 41, respectively, and an opening 42d for bolt fastening work is formed in the receiving plate portion 42a.

  When such a hole-down hardware 40 is attached to the pillar 20, as shown in FIG. 15, the shape and dimensions of the side plate portions 41b and 41c of the hardware main body 41 on the two opposing side surfaces 20a and 20b in the lower part of the pillar 20 in advance. Recesses 20c and 20d corresponding to the above are formed, the mounting surface 20e of the column 20 is placed on the upper surface 42a of the locking portion 42, and the body side surfaces 41c and 41d are fitted into the recesses 20c and 20d. The metal body side surfaces 41c and 41d are fixed to the pillar 20 with screws and / or bolts (both not shown).

  Although not shown in the drawings, the hole-down hardware 40 can also be provided with a guide hole for the bottom hole 41a below the bottom surface 41a of the hardware body 41. Further, the opening 42d of the locking portion 42 can be formed in a hexagonal shape as shown in FIG. 4 to provide a bolt head rotation prevention function. Furthermore, it is good also as a structure which attaches the bracing plate 30 as shown in FIG. 13 to the side surface of a hardware main body as needed.

  FIG. 16 shows a more specific embodiment in which the base anchor bolt 16 is connected by a double pulling pipe 55 that connects the anchor bolt 16 and the bolt 54 with the base packing 56 interposed therebetween. The hole-down hardware 11 may be joined to the base 35 by the pipe 55 and the bolt 54. Thus, in order to ensure ventilation under the floor, a base packing (foundation packing) 56 may be interposed between the foundation 61 and when the anchor bolt 16 is embedded too much in the foundation 61, the double-drawing pipe 55 is provided. The hardware 11 may be fixed to the base 35 with the bolts 54.

Although the above embodiment described the case where the hole-down hardware which is the structural joint hardware of the present invention is used for joining the base and the pillar, as shown in FIG. 17 , it is between the first floor and the second floor of the building. It can also be used when fixing columns to the top and bottom of a horizontal member, that is, a beam.
FIG. 17 shows a case where the hole down hardware shown in FIG. 1 is used. Moreover, in the figure, the same code | symbol is attached | subjected to the component same as FIG.

  That is, after inserting the guide holes 13 for the two hole-down hardware 10 into the relief holes 28 a formed on the upper surface and the lower surface of the beam 28, the bolts 16, washers 17 and nuts 18 The hole-down hardware 10 is fixed to the beam 28 at the same time. Subsequently, the receiving plate 12 is dropped into the hardware main body 11, and the upper and lower pillars 14 are accommodated in the hardware main body 11, and the pillar 14 and the side plate portions 11b and 11c of the hardware main body are fixed with screws 19, for example. .

In this state, if the pillar 14 and the hole-down hardware are fixed by the bolt 51 and the nut 52 and the drift pin 53 is inserted, the same effect as in the case of FIG. 4 can be obtained.
In the mounting structure described above, the hole-down hardware 10 having the brace plate shown in FIG. 13 may be used, and the brace may be fixed to the beam 28.
As described above, the structural joint hardware of the present invention, such as hole-down hardware, can of course be applied to conventional construction methods, but since there is no portion protruding from the pillar, a panel is provided between the pillars. When applied to the so-called panel construction method to be constructed, it is particularly useful because the degree of freedom of workability is increased as compared with conventional hole-down hardware.

In addition, since the structural joint hardware of the present invention can join the horizontal member and the pillar at the central axis of the pillar, it is separated from the central axis of the pillar as in the conventional hole-down hardware shown in FIG. Compared with the structure joined by the shaft, the force to withstand the pulling force is increased.
In addition, the structure is such that the column is sandwiched between the opposing side plate parts of the box-shaped joint hardware, so the bond strength with the column also increases compared to the conventional one, and it is particularly effective to prevent the column from shifting horizontally.
