Description

  The present invention relates to a square bar fixing tool and a square bar fixing method for fixing a square bar to a fixing target surface of a foundation wall such as a concrete wall.

  When installing equipment such as a joint box and a water pipe joint in the wall of a building, for example, as described in Patent Document 1, a beam is placed between light-weight shaped steel members that are erected at intervals. A horizontal member such as a batten is fixed by using a support or the like, and a joint box or a water supply pipe joint is fixed to the horizontal member with a screw or the like.

  On the other hand, when installing equipment such as water supply pipe joints on concrete walls, etc., or wiring and piping wiring materials and piping materials along the foundation wall such as concrete walls, equipment such as water pipe fittings, wiring materials, and piping materials In many cases, it is difficult to directly attach to a concrete wall or the like, so that a square member is attached to the concrete wall, and the appliance, wiring member, piping member, or the like is attached to the square member. Here, the square was fixed to the foundation wall by sticking with an adhesive. In the past, there was nothing to fix the square to the foundation wall using a fixture.

JP 2001-115509 A

  However, when fixing a square member to a concrete wall or the like by sticking with an adhesive, it is impossible to fix and support a wiring member, piping member or instrument to the square member until the adhesive is cured. It took time and work efficiency was low.

  Then, this invention makes it a subject to provide the fixing method of a square bar fixing tool and square bar which can fix a square bar to a foundation wall efficiently in a short time.

  The square member fixing tool according to claim 1 is a front plate applied to a surface of the square member that is abutted against a surface to be fixed and into which a nail or a screw is driven, and a surface of the square member that is fastened to the surface to be fixed. And a first wall connecting the fixing part and the front plate, and a second wall extending from the front plate so as to face the first wall, the front plate and the first wall The wall and the second wall constitute a receiving portion for receiving the square member. An elastic piece elastically contacting the square member in a state where the square member is disposed in the receiving portion is provided on at least one of the first wall and the second wall, and the square member fixing member is attached to the square member by the elastic piece. Temporarily attached.

The square member fixing device according to claim 2, in particular, a claw portion that protrudes toward the square member disposed in the receiving portion on the distal end side of the elastic piece and engages or is pressed against the outer surface of the square member so as to bite or damage the square member. Is provided.
The square member fixing tool according to claim 3 has an inclined surface that inclines toward the front plate as the claw portion protrudes.
In the square member fixing tool according to the fourth aspect, in particular, the claw portion has a cross-inclined portion that inclines in the direction intersecting the inclined surface at the tip portion.
The square member fixing tool according to claim 5 is provided with a prepared hole for driving a nail or a screw into the square member from the front side, particularly in the front plate.

A method for fixing a square bar according to claim 6 is to apply the square bar and the square bar fixing tool according to claim 5 to a surface to be fixed, and fix the square bar fixing tool to the fixing target surface by a fixing portion of the square bar fixing tool. The square bar is moved in the axial direction to adjust the position of the square bar, and a nail or a screw is driven into the square bar from a prepared hole of the square bar fixing tool to keep the square bar from slipping.
The square member fixing method according to claim 7 is a method in which the square member is attached to the surface to be fixed with an adhesive, and the square member fixing tool according to any one of claims 1 to 5 is attached to the square member before the adhesive is cured. Are temporarily fixed to the fixing target surface by the fixing portion of the square member fixing tool, and then the square member is moved in the axial direction to adjust the position of the square member.
According to an eighth aspect of the present invention, there is provided a square member fixing method in which the square member fixture according to any one of the first to fifth aspects is temporarily attached to the square member, and the square member and the square member are fixed to a surface to be fixed by gripping the square member. A tool is applied, and the square member fixing tool is fixed to the surface to be fixed by a fixing portion of the square member fixing tool.

In the inventions of claims 1 and 6 to 8, since the elastic piece elastically contacting the square bar is provided, when the square bar is arranged in the receiving part of the square bar fixing unit, the square bar is fixed by the elastic force of the elastic piece. A square is sandwiched between the first wall and the second wall, and temporarily attached to the square. As a result, the square bar fixing tool temporarily attached to the square bar by the elastic piece and the square bar are temporarily placed on the fixing target surface, and then the square bar fixing tool is fixed to the fixing target surface by the fixing portion, and then the square bar is fixed. Can be moved in the axial direction, so that the square bar can be adjusted to an optimum position while moving the square bar in the axial direction after fixing the square bar fixing tool at the approximate position of the surface to be fixed. easy. In addition, since the square bar is held by the square bar fixing tool after the square bar fixing tool is fixed to the fixing target surface, it is not necessary to always hold the square bar during alignment, and the square bar is simply moved along the fixing target plane. Since it is only necessary to make it work, workability is good. Furthermore, since the square bar can be gripped at a position away from the fixing part when fixing the square bar fixing tool, a nail or a screw can be safely driven into the fixing part.
Then, the square bar fixing tool is temporarily attached to the square bar by the elastic piece, so that the square bar fixing tool is temporarily attached to the square bar and then applied to the fixing target surface, and the square bar fixing tool is fixed by the fixing portion. In the case of fixing to a surface, it is possible to hold only the square bar, apply the square bar and the square bar fixing tool to the surface to be fixed, and drive nails and screws into the fixing part of the square bar fixing tool, so that workability is good.
From these things, a square bar can be efficiently fixed to the fixed object surface of a foundation wall in a short time.

  In addition, the elastic pieces can be inserted into and disposed in the receiving portions of the square member fixture corresponding to the square members having slightly different sizes, and the square member fixture can be temporarily attached.

  Here, in the case of the invention of claim 6, a nail or a screw can be driven into the square member from the prepared hole of the square member fixing tool and can be firmly fixed. In the case of the invention of claim 7, the square member can be firmly fixed to a predetermined position with an adhesive.

According to the second aspect of the present invention, since the claw portion of the elastic piece is locked or pressed so as to bite or damage the outer surface of the square bar, the square bar can be prevented from inadvertently moving in the axial direction.
According to the invention of claim 3, since the claw portion has an inclined surface inclined toward the front plate side, the square member can be smoothly inserted and arranged in the receiving portion.
Since the invention of claim 4 has the cross slope part which inclines in the direction which intersects the slope of claim 3 in the tip part of the claw part, it combined with the slope, the tip part of the claw part The contact area with the square member can be reduced by using a tapered shape, and the pressing force of the claw portion can be concentrated on a narrow range of the outer surface of the square member to strongly press the square member. On the other hand, the claw portion has an inclined surface and a cross-inclined portion, and the tip portion is inclined and has a tapered shape, so that the tip portion bites into the outer surface of the square member. The tip can be easily pulled out to the outside of the outer surface of the square bar, and the square bar can be reciprocated in the axial direction without receiving any special resistance. As a result, the work of adjusting the position by moving the square bar in the axial direction after fixing the square bar fixture to the surface to be fixed can be smoothly performed.

  According to the fifth aspect of the present invention, since the pilot hole is provided in the front plate, the square member is firmly fixed at a certain position of the square member fixing tool and then at a certain position of the fixing target surface by driving a nail or a screw into the square member from the front side. Can be fixed.

Hereinafter, a square member fixture according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 6 and the like, the square bar fixing tool is for fixing a square bar 61 to a fixing target surface 52 of a foundation wall 51 such as a concrete wall of a building.
The square member 61 is formed in the shape of a rectangular bar made of wood, foamed resin material, or the like, and wiring members, piping materials, water pipe fittings, and the like are attached thereto using screws or the like. In the present embodiment, the square member 61 is 30 mm wide and 30 mm high, or 30 mm wide and 33 mm high.

  The square member fixing tool 1 is formed of synthetic resin or the like, and as shown in FIGS. 1, 2, and 6, the fixing part 11 fixed to the fixing target surface 52 of the foundation wall 51 and the anti-fixing target surface of the square member 61. A front plate 21 applied to the side surface 62, a first wall 31 connecting the fixed portion 11 and the front plate 21, and a second wall extending from the front plate 21 so as to face the first wall 31. 41, and the front plate 21, the first wall 31, and the second wall 41 constitute a receiving portion 1a that receives the square member 61. The square member fixture 1 as a whole has a shape in which the receiving portion 1a is substantially U-shaped and the fixing portion 11 protrudes downward from the first wall 31 in parallel with the front plate 21. Further, the first wall 31 is provided with an elastic piece 33 that elastically contacts the square member 61 disposed in the receiving portion 1a. The square member fixture 1 has reinforcing ribs 1b erected along the end portions at both ends in the width direction.

  The fixing portion 11 is formed in a square plate shape, and a fixing hole 12 into which a nail or a screw is inserted and driven is formed in the center. A plurality of small conical small protrusions 13 that bite into the fixing target surface 52 are provided on the surface of the fixing portion 11 that contacts the fixing target surface 52 of the foundation wall 51, and four in this embodiment.

  The front plate 21 is formed in a square plate shape, and the back surface 23 opposite to the front surface 22, that is, the inner surface on the receiving portion 1 a side is applied to the surface 62 of the square member 61 on the anti-fixation target surface side. Here, the “front side” refers to the front side of the fixed target surface 52, that is, the side facing the fixed target surface 52. The “surface on the anti-fixation target surface side” of the square member 61 refers to a surface on the opposite side to the fixation target surface 52 of the foundation wall 51 in the square member 61, that is, the front surface. In a substantially central portion of the front plate 21, a pilot hole 24 is provided for driving nails and screws into the square member 61 from the front side.

  Next, the 1st wall 31 is between the fixing | fixed part 11 and the front plate 21, has comprised rectangular plate shape, and has connected the fixing | fixed part 11 and the front plate 21 in the parallel state which has the level | step difference L1. The step L <b> 1 is also a dimension in the depth direction of the first wall 31 and is formed to be 30 mm, which is the same as the width of the square member 61. The first wall 31 has a tapered surface whose plane portion is inclined slightly downward from a plane orthogonal to the front plate 21. Thereby, the opening of the receiving portion 1a expands downward, making it easy to insert the square member 61 therein, and the tapered surface also serves as a draft for taking out the square member fixture 1 from the molding die.

  At two locations in the width direction of the first wall 31, a notch space 32 that is communicated with the lower end portion of the front plate 21 from the middle in the depth direction is formed at an interval, and the notch space 32 is a substantially U-shape that leaves one side. It is formed in a shape. A rectangular elastic piece 33 extending in the direction of the front plate 21 with the one side as a base end and elastically bending inward and outward is provided in an inner portion of the cutout space 32. Further, a claw portion 34 that protrudes toward the square member 61 and has a substantially triangular prism shape is provided on the surface on the receiving portion 1a side of the distal end portion of the elastic piece 33 in the extending direction. The nail | claw part 34 has the inclined surface 35 which inclines toward the front plate 21 side from the upper surface of the elastic piece 33 as it protrudes. And the front-end | tip part of the nail | claw part 34 cross | intersects the inclined surface 35 on the right-and-left both sides of a width direction, and extends to the edge of the width direction of the elastic piece 33 from the front-end | tip top part 36, as shown in FIG.1 (b). A crossing inclined portion 37 having a triangular plane shape inclined downward is formed. That is, the claw portion 34 has a substantially quadrangular pyramid tapered pointed shape that is locked or pressed so that the tip portion bites or damages the outer surface of the square member 61. The side facing the front plate 21 in the claw portion 34 is formed as a vertical surface.

  Furthermore, small protrusions 39 extending from the lower end side of the front plate 21 toward the upper end of the fixing portion 11 are provided at three locations near the notch space 32 in the width direction on the surface of the first wall 31 on the receiving portion 1a side. It has been. The small protrusion 39 has a semicircular cross section, and its protruding height is 0 at the base point in contact with the front plate 21 and gradually increases linearly toward the fixed portion 11. The inclination angle formed between the straight line passing through the top of the small protrusion 39 and the plane portion of the first wall 31 is equal to the inclination angle of the tapered surface inclined downward of the plane portion of the first wall 31 described above. However, the inclination direction is completely reversed. That is, these inclination angles are canceled out, and the top of the small protrusion 39 intersects the front plate 21 at an angle of 90 degrees.

  The second wall 41 is formed in a rectangular plate shape, and extends in a substantially horizontal direction from the upper end portion of the front plate 21 so as to face the first wall 31. The length in the extending direction, that is, the dimension in the depth direction is the first. It is smaller than one wall 31. The second wall 41 is a tapered surface that is slightly inclined upward from a plane orthogonal to the front plate 21. As a result, the opening of the receiving portion 1a expands upward, and together with the tapered surface of the first wall 31, it is easy to insert the square member 61 into the interior, and the tapered surface is formed from the molding die to the square member fixing tool 1. It is also a draft for taking out.

  In addition, the inner surface of the second wall 41 on the receiving portion 1a side extends from the front plate 21 side toward the tip of the second wall 41 at three positions in the width direction facing the small protrusions 39 of the first wall. A small protrusion 42 is provided to protrude. The small protrusion 42 is formed in a semicircular cross section like the small protrusion 39 of the first wall 31, and its height is 0 at the base point in contact with the front plate 21, and is directed to the distal end on the fixed portion 11 side. It grows linearly gradually. The inclination angle formed between the straight line passing through the top of the small protrusion 42 and the flat portion of the second wall 41 is equal to the inclination angle of the tapered surface inclined above the flat portion of the second wall 41, provided that The direction of inclination is completely reversed. That is, the top of the small protrusion 42 intersects the front plate 21 at an angle of 90 degrees.

  Accordingly, the small ridge 39 of the first wall 31 and the small ridge 42 of the second wall 41 are in a parallel state with a constant interval extending in the entire depth direction of the receiving portion 1a. In the present embodiment, the interval L2 is set to 33 mm.

Next, a method of attaching the square member 61 to the fixing target surface 52 of the foundation wall 51 using the square member fixture 1 configured as described above will be described. In addition, the square member 61 shows the case where a 30 mm width and 30 mm height thing is attached.
First, the square member 61 is attached to the fixing target surface 52 of the foundation wall 51 with an adhesive. At this time, the square member 61 does not need to rule out the exact mounting position and align it with it, and is stuck to the approximate position of the surface 52 to be fixed.

  Next, before the adhesive is cured, as shown in FIGS. 3 (a), 4 and 5 (a), the square member fixing tool 1 is temporarily attached to the two portions of the square member 61 from the front side, Next, a nail or screw 53 is inserted into the fixing hole 12 of the fixing portion 11 and driven into the fixing target surface 52 to fix the square member fixture 1. Thereby, the square member 61 is supported by the square member fixture 1 as shown in FIG. 3 (b) and FIG. 5 (b). At this time, as shown in FIG. 5 (b), the claw portion 34 of the elastic piece 33 of the first wall 31 of the square member fixture 1 is pressed against the lower surface of the square member 61, and the elastic piece 33 is elastic around the base end 33a. Therefore, it bends slightly outside the first wall 31. Further, when the square member 61 is made of wood, the tip apex portion 36 of the claw 34 is locked so as to bite into the outer surface of the square member 61 or damage the front surface. When the square member 61 is made of a hard foamed resin material or the like, the tip apex portion 36 of the claw portion 34 is in pressure contact with the outer surface of the square member 61. The height of the square member 61 is 30 mm, and the distance L2 between the small protrusion 39 of the first wall 31 and the small protrusion 42 of the second wall 41 is 33 mm. Therefore, the lower surface of the square member 61 and the first wall 31 are used. A gap S of 3 mm is formed between the small protrusions 39.

  Subsequently, in the temporary holding state in which the square member 61 is supported by the square member fixture 1, as shown in FIG. 3B, the square member 61 is moved along the fixing target surface 52 in the axial direction indicated by the arrow, and the optimum position is obtained. Adjust to. At this time, the tip apex portion 36 of the claw portion 34 of the elastic piece 33 of the square member fixing tool 1 is engaged or pressed against the outer surface of the square member 61 so as to bite or damage the outer surface, but the claw portion 34 has an inclined surface 35. In addition, since the tip end portion is inclined with the cross inclined portion 37 and has a tapered pointed shape, the tip end portion is easily pulled out to the outside of the outer surface of the square member 61 when the moving operation is performed. Easy to reciprocate in the axial direction without receiving resistance.

  Thereafter, as shown in FIGS. 3 (c) and 3 (d), a nail or a screw 63 is inserted into the lower hole 24 of the front plate 21 of the square member fixing tool 1 from the front side and driven into the square member 61. The square member 61 is fixed. The state after fixation is shown in FIG. 3 (d), FIG. 5 (c), and FIG. As a result, the square member 61 is reliably prevented from being displaced with respect to the square member fixing tool 1, and thus is prevented from being displaced from the fixing target surface 52, and is held at the optimum position. Then, after the adhesive is cured, the square member 61 is more firmly held at a fixed position on the surface 52 to be fixed.

In the above embodiment, the square member 61 has a width of 30 mm and a height of 30 mm. However, when the square member 61 has a width of 30 mm and a height of 33 mm, the small protrusion 39 of the first wall 31 is used. And the small protrusion 42 of the second wall 41 is 33 mm. Therefore, when the square member 61 is inserted into the receiving portion 1a of the square member fixture 1, the bottom surface of the square member 61 and the small protrusion of the first wall 31 are disposed. No gap is formed between the strips 39, and the lower surface of the square member 61 reaches the entire small projection 39 of the first wall 31 and abuts evenly.
As described above, even when the height of the square member 61 is slightly different, the elastic piece 33 bends in a direction perpendicular to the plane of the first wall 31, so that the claw portion 34 always presses the lower surface of the square member 61 elastically. The square member 61 is sandwiched between the two walls 41.

  By the way, in this attachment method, first, the square member 61 is attached to the fixing target surface 52 of the foundation wall 51 with an adhesive, and then the square member fixing tool 1 is applied to the square member 61, and this is fixed by the fixing portion 11. The square member 61 is temporarily attached to the square member 61 and an adhesive is applied to the square member 61, and then the square member 61 and the square member fixture 1 are integrally fixed. It is also possible to fix the square member fixing tool 1 to the fixing target surface 52 by the fixing portion 11 after the temporary placement with respect to 52. Thereafter, similarly, before the adhesive is cured, the square member 61 is moved in the axial direction along the fixing target surface 52 in the temporary holding state in which the square member 61 is supported by the square member fixture 1. Adjust to the optimal position. By the way, in the case of this attachment, in the first work, the elastic piece 33 elastically holds the square member 61, and the side of the claw part 34 that faces the front plate 21 is formed on a vertical surface. Since the square member 61 is not easily pulled out by engaging with the outer surface of the square member 61, during the work until the square member 61 is gripped and applied to the fixation target surface 52 after temporarily attaching the square member fixing tool 1 to the square member 61, It is possible to prevent the square bar fixing tool 1 from being accidentally detached from the square bar 61 and falling.

Here, the relationship between the movement of the claw portion 34 of the elastic piece 33 of the square member fixture 1 and the square member 61 will be described.
Now, as shown in FIGS. 7 (e) and 7 (f), the claw portion of the elastic piece 33 of the square member fixing tool 1 is formed with a locking piece that is inclined only to one side at the tip of the elastic piece 33. Then, when the square member 61 is moved in the right direction as shown in FIG. 7 (e) in a state where the claw portion 71 made of the engagement piece is engaged with the outer surface of the square member 61, the catch with the claw portion 71 is small. The square member 61 can be moved without any particular trouble. However, when the square member 61 is moved in the left direction opposite to the inclination direction of the locking piece as shown in FIG. Therefore, the square member 61 is difficult to move.

  Therefore, if the claw portion of the elastic piece 33 is formed in a triangular prism shape having inclined surfaces on both sides from the tip top portion 72a of the claw portion 72, as shown in FIGS. When moving in any direction, the tip of the claw 72 is strongly hooked to the outer surface of the square member 61 and does not become a great resistance to the movement, so that the square member 61 can be moved in the left-right direction with relative ease. However, the claw portion 72 shown in FIGS. 7 (c) and (d) has a relatively small contact area with the square member 61. Compared with the claw portion 71 shown in FIGS. Although the sliding resistance generated between the outer surface and the outer surface is small, the tip apex portion 72a is a linear contact surface, so that a relatively large force is still required for movement, and it is difficult to move in directions other than the left and right. .

  With respect to these claw portions, the claw portion 34 of the square member fixing tool 1 of the present invention has an inclined surface 35 and a cross inclined portion 37 as shown in FIGS. It has a shape that approximates a quadrangular pyramid that is inclined on three surfaces, and is formed in a tapered pointed shape. The tip apex portion 36 of the claw 34 abuts the outer surface of the square member 61 in a substantially pointed state. For this reason, the square bar 61 is easy to reciprocate in the axial direction, and can be moved smoothly.

Next, the operation of the square bar fixing tool 1 of the present embodiment will be described.
Since the square piece fixing tool 1 is provided with the elastic piece 33 elastically contacting the square piece 61, when the square piece 61 is disposed in the receiving portion 1a, the elastic force of the elastic piece 33 causes the first wall 31 and the second wall 41 to Then, the square member 61 is sandwiched and temporarily attached to the square member 61. As a result, the square member 61 is temporarily placed on the fixing target surface 52, the square member fixing tool 1 is temporarily attached to the square member 61 by the elastic piece 33, and then the square member fixing tool 1 is fixed to the fixing target surface 52 by the fixing portion 11. Then, since the square member 61 can be moved in the axial direction, an accurate attachment position of the square member 61 is first marked on the surface 52 to be fixed, and then the square member 61 is aligned with the ruled line to fix the square member fixture. Without the troublesome work of fixing 1 to the fixing target surface 52, the square member 61 is temporarily arranged at the approximate position of the fixing target surface 52 and then adjusted to the optimal position while moving in the axial direction. Easy to work with. Further, since the square bar 61 after the square bar fixing tool 1 is fixed to the fixing target surface 52 is held by the square bar fixing tool 1, it is not necessary to always hold the square bar 61 during the alignment, and the square bar 61 is simply fixed. Workability is good because the alignment may be performed while moving along the surface 52. Furthermore, since the square member 61 can be gripped at a position away from the fixed portion 11, a work of driving a nail or a screw into the fixed portion 11 can be performed safely.

Then, since the square member fixture 1 is temporarily attached to the square member 61 by the elastic piece 33, the square member fixture 1 is temporarily attached to the square member 61, and then these are integrally attached to the fixing target surface 52. When the square member fixing tool 1 is fixed to the fixing target surface 52, only the square member 61 is gripped, the square member 61 and the square member fixing tool 1 are integrally attached to the fixing target surface 52, and the nail is attached to the fixing portion 11 of the square member fixing tool 1. Workability is good because it can drive in and screws.
For these reasons, the square member 61 can be efficiently fixed to the fixing target surface 52 of the foundation wall 51 in a short time.

  In addition, since the elastic piece 33 is provided, the square member 61 can be temporarily attached to the square member 61 having a slightly different size by inserting it into the receiving portion 1a of the square member fixture 1.

  Further, the claw portion 34 of the elastic piece 33 is locked or pressed so as to bite or damage the outer surface of the square member 61. In addition, the claw portion 34 has an inclined surface 35 and has a cross-inclined portion 37 that is inclined in a direction intersecting the inclined surface 35 at the front end portion, so that the front end portion of the claw portion 34 has a tapered shape. Since the contact area with the square member 61 is small, the tip apex portion 36 is intensively and strongly pressed to a narrow range of the outer surface of the square member 61. For these reasons, the square member 61 is stably and temporarily held by the square member fixture 1, and the accidental movement in the axial direction is suppressed.

On the other hand, the claw portion 34 has an inclined surface 35 and a cross-inclined portion 37, and the tip portion is inclined and has a tapered shape, so that the tip portion bites into the outer surface of the square member 61. In this state, the tip portion can be easily pulled out to the outside of the outer surface of the square member 61. Therefore, the square member 61 can be reciprocated in the axial direction without receiving any particular resistance. As a result, the work of adjusting the position by moving the square member 61 in the axial direction after fixing the square member fixing tool 1 to the fixation target surface 52 can be performed smoothly.
In addition, since the nail | claw part 34 has the inclined surface 35, the square material 61 can be smoothly inserted and arrange | positioned in the receiving part 1a.

Next, another square member fixture 1 of the present invention is shown in FIG.
In FIG. 8, the square bar fixing tool 1 is different from the square bar fixing tool 1 shown in FIGS. The fixed portion 11 of the square bar fixing tool 1 shown in FIG. 8 has an inner cylindrical portion 14 erected integrally with the outer peripheral portion of the fixed hole 12. A plurality of arc plate-like blade portions 15 having the same length as this height are provided on the outer circumferential surface of the inner cylindrical portion 14 so as to protrude in the outer circumferential direction at a predetermined interval in the circumferential direction. Further, an outer cylindrical portion 16 having a smaller height than the inner cylindrical portion 14 is provided outside the blade portion 15.

  Gas nailers are often used when nails or screws are inserted into the fixing holes 12 of the fixing portion 11 and driven into a very hard foundation wall 51 such as a concrete wall. However, since the gas nailer drives nails and the like at a high pressure, the fixed portion 11 may be broken by the impact pressure. For this reason, in the square bar fixing tool 1 shown in FIG. 8, the inner cylindrical portion 14 and the outer cylindrical portion 16 are provided in the outer peripheral portion of the fixing hole 12. When these cylindrical portions are present, the fixing portion 11 is reinforced and cracks during driving can be prevented. These cylindrical portions also serve as guides for driving nails and the like.

  By the way, although the elastic piece 33 of the said embodiment is provided in the 1st wall 31, you may provide in the 2nd wall 41, or you may provide in both the 1st wall 31 and the 2nd wall 41. . Moreover, although the elastic piece 33 is provided in two places of the 1st wall 31, it is not limited to this.

In addition, the tip of the claw portion 34 of the elastic piece 33 of the above embodiment has an inclined surface 35 and an intersecting inclined portion 37 inclined in a direction intersecting the inclined surface 35, on the side facing the front plate 21. Although the surface is formed as a vertical surface, the tip of the surface facing the front plate 21 may also be formed as an inclined surface, that is, all four surfaces of the tip may be formed as inclined surfaces. Further, the tip of the claw 34 may be formed in another polygonal pyramid shape, a conical shape, an elliptical cone shape, or the like.
In addition, the intersecting inclined portion 37 of the claw portion 34 is formed in a triangular planar shape, but may be formed by a protrusion or the like sharpened in a mountain shape.
And the nail | claw part 34 is not limited to these shapes, Moreover, the nail | claw part 34 may differ in shape.

  Furthermore, in the above embodiment, the square member 61 is fixed to the foundation wall 51 by sticking using an adhesive, and a nail or the like is driven into the lower hole 24 of the front plate 21 of the square member fixture 1 to the foundation wall 51. Although fixed, it may be fixed to the foundation wall 51 by only one of these means. In addition, when fixing the square member 61 to the foundation wall 51 by adhesion of an adhesive, the pilot hole 24 for driving a nail or the like may be unnecessary.

Moreover, although the square member fixing tool 1 of the said embodiment is each attached to the right and left of the square member 61, when the square member 61 is long etc., you may attach to three or more places.
Furthermore, although the square bar fixing tool 1 of the said embodiment is attached to the square bar 61 in the direction in which the fixing | fixed part 11 becomes a lower side, you may attach in the direction in which the fixing | fixed part 11 becomes a reverse upper side. Depending on the height at which the square member 61 is attached to the fixing target surface 52 of the foundation wall 51, when the fixing portion 11 is fixed to the fixing target surface 52, it is easier to work when the fixing portion 11 is attached in an upward direction. Because there is.

  In addition, a small protrusion 39 protrudes from the first wall 31 and a small protrusion 42 protrudes from the second wall 41. The small protrusion is either the first wall 31 or the second wall 41. It may be provided only on one side, or may not be provided on either side. Moreover, the number which provides a small protrusion on each said wall is also not ask | required.

  In addition, although the square bar 61 used by the said embodiment is formed in the rectangular rod shape, this invention is not necessarily limited and applied to the square bar 61 of this shape.
