JP 2002-206276 A

The above-described conventional structure supports the shape member so that it does not move in the longitudinal direction by inserting (engraving) the lock portion of the fixing bracket into the shape member. Is formed so that the lower end surface of the downward piece is formed in a saw-tooth shape, and the biting shape into the shape member by the plurality of locking claws is straight along the longitudinal direction of the shape member.
Therefore, when a large force acting in the longitudinal direction acts on the profile, the profile may move in the longitudinal direction.

  An object of the present invention is to provide a structure capable of firmly supporting a shape member.

The present invention is a structure in which a plurality of shape members are arranged in a shape member mounting portion, and a plurality of longitudinal direction portions of each shape member are supported by the shape member mounting portion with a fixing bracket, A mounting piece fixed to the material mounting portion with a screw, a rising piece provided on the mounting piece, and a laterally protruding piece provided at the upper end portion of the rising piece and directed in the width direction or the longitudinal direction of the shape member. A pair of protruding locking claws are provided on the laterally projecting piece, and the pair of locking claws bite into the shape member while forming a C shape so that one side or the other side in the width direction is expanded, The locking claw includes a first end surface continuous with the protruding end surface facing the protruding direction of the laterally protruding piece, a second end surface continuous with the longitudinal end surface of the laterally protruding piece facing the longitudinal direction, and the laterally protruding piece. An outer surface continuous with the upper surface of the inner surface, an inner surface continuous with the lower surface of the laterally projecting piece, A ridge line connecting the upper end point forming the boundary between the first end surface, the second end surface and the outer surface, and the lower end point forming the boundary between the first end surface, the second end surface and the inner surface; The ridge line is slanted so that the lower portion of the outer surface is above the lower portion of the inner surface, and the protruding end surface facing the protruding direction of the lateral protruding piece and the first end surface of the locking claw are formed flush with each other, On the lower end side from the upper end point, the inner angle formed by the two sides of the inner surface, the inner angle formed by the two sides of the first end surface, and the inner angle formed by the two sides of the second end surface, with the lower end point as the vertex of the corner, A structure having an acute angle.
Here, examples of the structure include a deck, a floor, a fence, a wall, a fence, a bench, and the like. Moreover, as a shape material, the extrusion material etc. which mixed wood powder and resin and extrusion-molded are mentioned.

In the present invention, the pair of locking claws can be formed by bending the front end corner of the laterally projecting piece.
By doing in this way, a latching claw can be formed easily.

In the present invention, the rising piece rises from at least one side in the width direction of the mounting piece,
The laterally projecting piece can be provided so as to project from the upper end of the rising piece toward the one side in the width direction.
By doing in this way, since a latching claw can be made to bite into the shape material in the position near the width direction center of a shape material, a shape material can be supported firmly.
In addition, compared to the case where the laterally projecting piece projects from the upper end of the rising piece that rises from at least one side in the width direction of the mounting piece to the other side in the width direction, the projecting direction of the laterally projecting piece The length can be shortened and the cost can be reduced.

In the present invention, the end face in the width direction of the profile can be in contact with the rising piece of the fixture.
In this way, when the profile is about to move in the longitudinal direction, the direction of movement of the profile is regulated in the direction along the square shape by the biting claw. In other words, it tries to move obliquely with respect to the longitudinal direction. However, since the end face in the width direction of the profile abuts against the rising piece of the fixing bracket and the movement in the width direction is restricted, the profile is inclined with respect to the longitudinal direction. Can't move. Accordingly, it is possible to more reliably prevent the shape member from moving in the longitudinal direction.

In the present invention, the profile has attached pieces at both ends in the width direction,
The fixing bracket includes a rising piece that rises from the other side in the width direction of the mounting piece, and a laterally protruding piece on the other side that protrudes from the upper end of the rising piece on the other side toward the other side in the width direction,
Only one laterally projecting piece has a pair of locking claws, and this one laterally projecting piece is in contact with the upper surface of the attached piece at the other side end portion in the width direction of the adjacent one side member. The laterally projecting piece on the side can be in contact with the upper surface of the attached piece at the one end in the width direction of the adjacent shape member on the other side.
In this way, after supporting the adjacent one shape member so as not to move in the longitudinal direction with the fixing bracket, the other adjacent between the laterally projecting piece on the other side of the fixing bracket and the shape attachment portion. The attached piece at the other end in the width direction of the side shape member can be pushed in and supported.

According to the present invention, since the pair of locking claws of the laterally protruding piece of the fixing metal bite into the shape member in a C shape in plan view with respect to the shape member, the resistance to movement in the longitudinal direction is large.
Therefore, the profile can be firmly supported so as not to move in the longitudinal direction.
Further, in the conventional structure, the tip of the serrated locking claw has a predetermined width (the thickness of the downward piece) in the direction orthogonal to the longitudinal direction of the shape member. Although the area is large and the depth of biting into the shape is shallow, according to the present invention, the tip of the locking claw has a sharp shape, so that the depth of biting into the shape becomes deep.
Moreover, while the front-end | tip part of a latching claw is comprised by three surfaces and the front end side of these three surfaces becomes an acute angle, the front-end | tip of a latching claw becomes a sharper shape.

As shown in FIG. 1, a plurality of joists 1 are fixedly attached to a fixing portion (not shown) to form a shape attaching portion.
A deck material 2 as a plurality of profile members is arranged across the plurality of joists 1. The joist 1 and the deck material 2 are orthogonal to each other.
The deck material 2 is an extruded material obtained by mixing wood powder and resin, and the extrusion direction of the deck material 2 is the longitudinal direction of the deck material 2. The material of the deck material 2 is not limited to this, and other materials may be used. Further, the width direction of the deck material 2 refers to the parallel direction of the plurality of deck materials 2. Hereinafter, the longitudinal direction refers to the longitudinal direction of the deck material 2, and the width direction refers to the width direction of the deck material 2.
A plurality of longitudinal positions of the deck material 2 are pressed against and supported by the joist 1 with a fixing bracket 3 to form a deck. This deck is a structure.
For example, as shown in FIG. 2, a fixing bracket 3 is fixedly attached with screws 4 between adjacent deck members 2 in each joist 1 and the deck member 2 is pressed against the joists 1 and fixed with the fixing bracket 3. .

  The joist 1 is a long material having a rectangular cross section having an upper surface plate 10, a lower surface plate 11, and a pair of side plates 12, and the deck material 2 is placed on the upper surface plate 10.

The deck material 2 has a mounted piece 20 that protrudes in the width direction from the end surface in the width direction at both lower portions in the width direction, and the lower surface 20a of the mounted piece 20 and the lower surface 2a of the deck material 2 are continuous with each other. doing.
For example, the deck material 2 is a long material having a substantially rectangular cross section having a hollow portion 25 with an upper surface plate 21, a lower surface plate 22, end surface plates 23 at both ends in the width direction, and vertical ribs 24, and the end surface plate 23 extends from the top to the bottom. The bottom plate 22 is bent in a step shape toward the center in the width direction, and protrudes in the width direction from the end face plate 23 to form the above-described attached piece 20. The attached piece 20 and the end face plate 23 are also provided. A recessed portion 26 is formed near the lower portion of the groove.

As shown in FIGS. 3 and 4, the fixture 3 includes a mounting piece 30 fixed to the upper surface 1 a (upper surface plate 10) of the joist 1 with screws 4, and one end in the width direction of the mounting piece 30 (the joist 1. The rising piece 31 (one rising piece on one side) provided at the end of the rising piece 31 and the lateral protruding piece extending in the width direction provided protruding from the upper end of the rising piece 31 toward one side in the width direction. 32 and has a pair of locking claws 33 that are bent downward at the corners of the front end corners in the width direction of the laterally projecting pieces 32.
The pair of locking claws 33 have a square shape in which the other side in the width direction is widened when the fixing bracket 3 is viewed from a plane.
The front end portion 33a of each locking piece 33 is sharp and pointed.

Thus, by attaching the attachment piece 30 of the fixing bracket 3 to the upper surface 1a of the joist 1 with the screws 4, the pair of locking claws 33 are attached to the attachment piece 20 of the deck material 2 on one side. Thus, the deck material 2 can be supported so as not to move in the longitudinal direction by being bitten into a square shape in plan view.
Since the tip end portions 33a of the pair of locking claws 33 have a pointed shape, the tip end portion 33a can be deeply bitten into the attached piece 20 at the other end in the width direction of the deck material 2.
Further, the pair of locking claws 33 have a C-shape in plan view, and the locking claws 33 do not bite in parallel with the longitudinal direction of the deck material 2, so the resistance force of the deck material 2 to move in the longitudinal direction is large. Become.
Further, the other end surface in the width direction of the deck material 2 (the end surface of the attached piece 20) is in contact with the rising piece 31 of the fixture 3.
When the deck material 2 is about to move in the longitudinal direction, the direction of movement of the shape material is regulated in the direction along the square shape by the biting engagement claw 33. That is, although it tries to move diagonally with respect to the longitudinal direction, the other end surface in the width direction of the deck material 2 (the end surface 20b of the attached piece 20) contacts the rising piece 31 in the width direction (arrow a in FIG. 4). Therefore, the deck material 2 cannot move obliquely with respect to the longitudinal direction.

Accordingly, the deck material 2 can be firmly supported by the joists 1 so as not to move in the longitudinal direction, and the deck material 2 does not move in the longitudinal direction even if a large force is applied to the deck material 2 in the longitudinal direction. .
Even if the other end surface in the width direction of the deck material 2 and the rising piece 31 of the fixing bracket 3 are mounted separately, the deck material 2 can be supported so as not to move in the longitudinal direction.

Further, since the locking claw 33 is provided only at the front end corner in the width direction of the laterally projecting piece 32 and the distance in the longitudinal direction between the pair of locking claws 33 is substantially the same as the entire length in the longitudinal direction of the fixture 3, The interval in the longitudinal direction of the portion where the locking claw 33 in the deck material 2 bites is wide, so that the deck material 2 is less damaged by the biting of the locking claw 33, and the deck material 2 is locked into the locking claw 33. The phenomenon of rotating around the center becomes difficult to occur.
That is, if the interval between the portions where the latching claws 33 bite is small, the latching claws 33 bite into the adjacent biting portions, causing cracks or the like to be damaged, or during construction or after construction. In this case, the deck material 2 may rotate around the locking claw 33.

Next, the shape of the locking claw 33 will be described with reference to FIGS.
The locking claw 33 has a first end surface 33b continuous with the protruding end surface 32a facing the protruding direction of the laterally projecting piece 32 and a second end surface 33c continuous with the longitudinal direction end surface 32b facing the longitudinal direction of the laterally protruding piece 32. A triangular outer surface 33d continuous with the upper surface 32c of the laterally projecting piece 32, a triangular inner surface 33e continuous with the lower surface 32d of the laterally projecting piece 32, and a first end surface 33b, a second end surface 33c, and an outer surface. It has a ridge line 33f connecting an upper end point 33h that forms a boundary with 33d and a lower end point 33i that forms a boundary between the first end surface 33b, the second end surface 33c, and the inner side surface 33e.
The first end surface 33b and the second end surface 33c are continuous in a V shape.
Each of the outer side surface 33d and the inner side surface 33e has a triangular shape having three sides that are a boundary line with the first end surface 33b, a boundary line with the second end surface 33c, and a broken line at the bent portion.
The ridge line 33f is slanted so that the lower portion of the outer surface 33d is above the lower portion of the inner surface 33e, and the upper end point 33h is above the lower end point 33i.
The projecting end surface 32a of the laterally projecting piece 32 and the first end surface 33b of the locking claw 33 are formed flush with each other, and on the lower end point 33i side from the upper end point 33h, the lower end point 33i is the corner apex, and the inner side surface 33e. Of the two sides (boundary lines between the inner side surface 33e and the first end surface 33b and the second end surface 33c) and two sides of the first end surface 33b (the first end surface 33b, the inner side surface 33e and the second end surface 33c). The inner angle formed by the boundary line) and the inner angle formed by the two sides of the second end surface 33c (the boundary line between the second end surface 33c and the inner surface 33e and the first end surface 33b) are acute angles.

  As a result, the front end portion of the locking claw 33 is constituted by three surfaces (first end surface 33b, second end surface 33c, and inner side surface 33e), and the front end side (lower end point 33i side) of these three surfaces is Since it becomes an acute angle, since the front-end | tip (lower end point 33i part) of the latching claw 33 becomes a sharp shape, the depth which bites into the deck material 2 becomes deep.

The fixing bracket 3 of this embodiment is provided with a rising piece 31 (an upstanding piece on the other side) at the other end in the width direction of the mounting piece 30, and a laterally projecting piece 32 is provided on the rising piece 31 on the other side. It is provided.
And the latching claw 33 is formed in the horizontal protrusion piece 32 of the width direction one side, and the latching claw 33 is not formed in the horizontal protrusion piece 32 of the width direction other side.
Since this is the case, as shown in FIG. 3, the laterally projecting piece 32 on one side in the width direction is in contact with the upper surface of the attached piece 20 at the other end in the width direction of the adjacent deck material 2 on the one side. 33, the attached piece 20 at the one end in the width direction of the deck material 2 on the other side adjacent between the laterally projecting piece 32 on the other side in the width direction and the upper surface 1a of the joist 1 is attached. The deck material 2 can be temporarily attached by pushing and holding.
The temporarily attached deck material 2 on the other side is attached by holding the attached piece 20 on the other side end in the width direction so as not to move in the longitudinal direction using the fixing bracket 3 as described above.
In addition, the laterally projecting piece 32 on the other side in the width direction is inclined downward so that the tip portion is downward with respect to a right angle with the rising piece 31.

Next, a manufacturing method of the fixing bracket 3 will be described.
As shown in FIG. 7A, one plate material is bent into a shape having a mounting piece 30, a pair of rising pieces 31, and a pair of laterally projecting pieces 32.
The laterally projecting piece 32 on one side in the width direction is perpendicular to the rising piece 31, and the laterally projecting piece 32 on the other side is an angle whose inner angle formed with the rising piece 31 is smaller than the right angle.
Next, a corner portion 34 which is a front end corner portion in the width direction of the laterally projecting piece 32 on one side, for example, a line 32f connecting positions at equal distances from the projecting end surface 32a of the laterally projecting piece 32 and the corner portion 32e in the longitudinal end surface 32b. Further, the portion closer to the corner 32e is bent 90 degrees downward from the line 32f as shown in FIG. Note that the angle of bending downward may be other than 90 degrees, but is preferably 90 degrees or less, more preferably 90 degrees.

Thereafter, the middle of the projecting direction of the laterally projecting piece 32 is cut at right angles (perpendicular) to the upper and lower surfaces 32c and 32d along the cutting line 32g indicated by a dotted line over the entire length in the longitudinal direction, thereby cutting the downward piece 35. To do.
Specifically, in the width direction, the position of the cutting line 32g is the same position as the vertex that forms the boundary between the projecting end surface 32a, the longitudinal end surface 32b, and the lower surface 32d, or the other side in the width direction (laterally projecting piece). 32 in the opposite direction to the protruding direction).
The cutting line 32g is parallel to the longitudinal direction of the deck material 2, traverses the middle of the projecting direction of the downward piece 35, and the middle of the projecting direction of the pair of downward pieces 35 is cut and removed. The remaining portion of 35 is used as a locking claw 33 as shown in FIG.

Since it is like this, the fixing metal fitting 3 provided with the protrusion horizontal piece 32 which has the latching nail | claw 33 can be manufactured by bend | cutting after bending one board | plate material, and the manufacture is easy.
Moreover, since the laterally projecting piece 32 before cutting has a sufficient projecting length, even a thick plate material can be easily bent and manufactured.

As shown in FIG. 1, the deck material 2 is supported by fixing brackets 3 at a plurality of locations in the longitudinal direction facing a plurality of joists 1.
The fixing bracket 3 at one end in the longitudinal direction is a fixing bracket provided with the laterally protruding pieces 32 having the locking claws 33 described above, and supports one end in the longitudinal direction of the deck material 2 so as not to move in the longitudinal direction.
The fixing brackets 3 other than the fixing bracket 3 at one end in the longitudinal direction are fixing brackets provided with the laterally projecting pieces 32 that do not have the locking pieces 33 described above, and can move in the longitudinal direction at a plurality of longitudinal positions of the deck material 2. I support it so that it does not float up.

  For example, as shown in FIG. 8, the mounting piece 30, the rising piece 31, and the laterally projecting piece 32 are attached, and the laterally projecting piece 32 is attached to the joist 1 with a screw 4. 2 to be pressed against and supported by the two attached pieces 20.

  As described above, when the deck material 2 is thermally expanded and contracted, the deck material 2 can be prevented from curving upward or cracking due to thermal expansion and contraction by sliding in the longitudinal direction around one end in the longitudinal direction. The end surfaces 2b (small edge surfaces) in the longitudinal direction of the plurality of deck materials 2 can be aligned.

In the above-described embodiment, the deck material is supported by using the fixing bracket 3 having the laterally projecting piece 32 having the latching claw 33 and the fixing bracket 3 having the laterally projecting piece 32 not having the latching claw 33. However, the deck material 2 may be supported only by the fixing bracket 3 provided with the laterally projecting pieces 32 having the locking claws 33.
Alternatively, only the laterally projecting piece 32, the rising piece 31, and the attachment piece 30 having the locking claw 33 may be used as the fixing bracket 3. In this case, the mounting piece 20 at the one end in the width direction of the deck material 2 on the other side is used by using the fixing bracket 3 having only the laterally protruding piece 32, the rising piece 31 and the mounting piece 30 without the latching claw 33. Try to support it.
Moreover, although the latching claw 33 was formed only in the front-end | tip corner | angular part of the width direction of the horizontal protrusion piece 32, it is also possible to form an auxiliary latching claw in the middle of a longitudinal direction.
Moreover, in the above-mentioned embodiment, although it was set as the fixing metal fitting 3 provided with the horizontal protrusion piece 32 which has the latching claw 33 by carrying out the cutting process after bending the one board | plate material, it is not restricted to this.
For example, the tip of the locking claw may be sharpened by hitting one plate material and crushing it thinly and then bending and cutting.
Further, as shown in FIG. 9, the rising piece 31 is raised from one side and the other side of the mounting piece 30 in the longitudinal direction of the deck material, and the laterally projecting piece 32 is extended from the upper end of the rising piece 31 to the one side in the longitudinal direction of the deck material. It is good also as a shape which protruded toward the other side and protruded toward the width direction one side and the other side of the deck material.
In this case, the rising piece 31 is raised only from one side of the mounting piece 30 in the longitudinal direction of the deck material, and the laterally projecting piece 32 is provided so as to protrude from the upper end of the rising piece 31 toward the longitudinal direction of the deck material. It is good also as a shape which protruded the protrusion piece 32 toward both the width direction one side and the other side (or only the deck material width direction one side).
In the above embodiment, the deck is used as the structure. However, the structure is not limited to this, and may be a floor, a fence, a wall, a fence, a bench, or the like. In addition, as the shape material, an extruded material obtained by mixing and mixing woody powder and resin was mentioned.
