Description

  The present invention relates to a metal square column with an anti-fretting device used as a metal base material in interior and exterior construction of a building.

  Commonly used metal base materials used for interior construction of buildings are specified in Japanese Industrial Standards JIS A6517 steel base materials for construction (walls, ceilings), and are specified as wall materials. As such studs, those having a U-shaped cross section are known. This wall material stud is surrounded by metal on three sides, but the remaining one side is an open part, so one or more anti-freight through holes are provided on the opposite side of the open part, There was a problem that it could not be used unless the base material was reinforced through this channel.

  This open portion is formed in an overbend shape so that the U-shaped end portions face each other in order to prevent the open portion from being displaced by fitting a spacer which is another member.

  Since both sides of this overbend-shaped surface are naturally board-bonding surfaces, a spacer to correct overbend is fitted in the open part, but the part where the spacer is fitted is a point, the other part Then it remains in an overbend state. In this case, when the joint between the boards comes to the part that remains in the overbend state, there is a problem that a difference in level is generated at the joint.

  Therefore, the present applicant has a front side notch opening having a channel fitting groove for fitting a channel for anti-fretting on two opposite surfaces of a hollow metal square column, and the front side notch. A back-side cutout opening opposite to the opening is formed, and the back-side cutout opening is openable and closable at one side edge of the backside cutout opening, and is pressed against the upper surface of the channel when closed. An application has been filed for a metal prismatic column with an anti-fretting device having a configuration in which a pressure-fixing piece having a pressure-contact tongue portion protruding integrally is provided (see Patent Document 1).

JP-A-8-218520.

  However, in the case of the technique disclosed in Patent Document 1, a large upward force may act on the pressure contact fixing piece due to the pressure contact between the pressure contact tongue and the channel upper surface when the pressure contact fixing piece is closed. There is a possibility that the channel may be deformed upward and the channel cannot be securely pressed and fixed. Further, in the case of the technique disclosed in the above-mentioned Patent Document 1, there is a problem that the flare prevention cannot be performed depending on the shape of the channel, or there is no degree of freedom in the posture of the channel and the directionality is limited. . In addition, when the plate thickness is thick, the bending portion of the pressure contact fixing piece has high rigidity, which may cause a problem that it is difficult to open and close by hand.

  The present invention has been made in view of the above points, and can be applied to any shape of anti-fretting member, and is a low-cost, all-purpose metal corner with an anti-fretting device that does not take any directionality into consideration. The purpose is to provide a column.

  In the present invention, as a first means for solving the above-described problem, the notch openings 9 and 10 for inserting and supporting the anti-fretting member 11 on the two opposing surfaces 5 and 6 of the hollow square metal column 1 are provided. , And positioning portions 13 and 13 for positioning the anti-fretting member 11 are provided in the notch openings 9 and 10, respectively, and the movement of the anti-fretting member 11 is performed on the peripheral portions of the notch openings 9 and 10. A movement restricting means 15 for restricting is attached.

  With the configuration described above, the movement of the anti-fretting member 11 positioned at the positioning portions 13 and 13 of the notch openings 9 and 10 can be performed only by attaching the movement restricting means 15 to the peripheral portions of the notch openings 9 and 10. Regardless of the shape of the notches 9 and 10 and the cross-sectional shape of the anti-fretting member 11, the anti-fretting member 11 and the metal quadrangular column 1 can be firmly coupled.

  In the present invention, as a second means for solving the above-described problem, in the metal square pillar with a fretting device provided with the first means, the movement restricting means 15 is replaced with the fretting member 11. A movement restricting portion 16 that restricts the movement of the moving restricting portion 16 and fitting insertion fixing pieces 17 and 17 that are integrally projected from both sides of the movement restricting portion 16 toward the mouth edges of the cutout openings 9 and 10. A pair of insertion holes 14, 14 for inserting the insertion fixing pieces 17, 17 into the respective peripheral edges of the cutout openings 9, 10 can be formed. Just by inserting the insertion fixing pieces 17 and 17 into the insertion holes 14 and 14 formed in the peripheral portions of the openings 9 and 10, respectively, the anti-fretting member 11 is inserted into the peripheral portions of the cutout openings 9 and 10. The movement restricting means 15 can be attached Next, the workability is improved.

Due to the presence of the gap S, the movement restricting means 15 can be easily attached, and the movement restriction of the anti-fretting member 11 can be reliably performed.

  According to the first means of the present invention, the notched openings 9 and 10 for inserting and supporting the anti-fretting member 11 are formed on the two opposite surfaces 5 and 6 of the hollow metal square column 1, respectively. Positioning portions 13 and 13 for positioning the anti-fretting member 11 are provided in the notch openings 9 and 10, respectively, and movement restricting means 15 for restricting the movement of the anti-fretting member 11 at the peripheral portions of the notch openings 9 and 10. And the movement restricting means 15 is attached to the peripheral portions of the notch openings 9 and 10 so that the movement of the anti-fretting member 11 positioned at the positioning portions 13 and 13 of the notch openings 9 and 10 is restricted. Therefore, regardless of the shape of the cutout openings 9 and 10 and the cross-sectional shape of the anti-fretting member 11, there is an effect that the anti-fretting member 11 and the metal square column 1 can be firmly coupled.

  As in the second means of the present invention, in the metal square pillar with a fretting device provided with the first means, the movement restricting means 15 is a movement restricting portion that restricts the movement of the fretting member 11. 16 and fitting insertion fixing pieces 17 and 17 projecting integrally from both sides of the movement restricting portion 16 toward the mouth edges of the cutout openings 9 and 10, and both sides of the cutout openings 9 and 10. A pair of insertion holes 14 and 14 for inserting the insertion fixing pieces 17 and 17 into the peripheral portion can be formed, respectively. In such a case, the peripheral portions of the notch openings 9 and 10 are formed. The movement restricting means 15 can be attached to the peripheral portions of the cutout openings 9 and 10 simply by inserting the insertion fixing pieces 17 and 17 into the formed insertion holes 14 and 14, respectively. As a result, workability is improved.

  As in the third means of the present invention, in the metal square pillar with anti-fretting device having the second means, a slight gap S is provided between the movement restricting portion 16 and the anti-fretting member 11. In such a configuration, even if a slight dimensional error occurs in the movement restricting portion 16 of the anti-flection member 11 or the movement restricting means 15, the movement restricting means due to the presence of the gap S. 15 can be easily attached, and the movement restriction of the anti-fretting member 11 can be reliably performed.

  Hereinafter, several preferred embodiments of the present invention will be described with reference to the accompanying drawings.

First Embodiment FIGS. 1 to 3 show a metal prismatic column with an anti-fretting device according to a first embodiment of the present invention.

  As shown in FIG. 1, the metal prismatic column with an anti-fretting device is configured by bending a metal plate cut into a predetermined width into a square tube shape so that both ends thereof are in contact at one corner. It is constituted by a hollow metal square column 1.

  At one end of the metal plate, there is provided an inverted J-shaped bent portion 3 which is bent inside the metal quadrangular column 1 and further bent at the tip thereof toward the outside. The other end portion of the metal plate is provided with an inverted U-shaped bent portion 4 that is bent in an inverted U shape on the inner side, and the upper and lower sides are continuously fitted and crimped together. It is formed as a corner type connecting portion 2 that is continuous in the direction. And the rib 12 which protrudes in a U-shape toward the inner side from the base end of the inverted U-shaped bending part 4 in this corner type connection part 2 is formed continuously in the up-down direction. With this configuration, any of the four surfaces 5 to 8 of the metal square column 1 can be selected as a notch opening forming portion and a board pasting surface, which will be described later, and the corner type connecting portion 2 is detached. Can be prevented by the ribs 12 and the rigidity of the metal square column 1 can be enhanced.

  Two opposing surfaces 5 and 6 of the four surfaces 5 to 8 of the metal quadrangular column 1 are a front surface and a back surface, and the front surface 5 and the back surface 6 have, for example, a U-shaped cross section at a substantially central portion in the lateral direction. The substantially rectangular cutout openings 9 and 10 for inserting the metal-shaped anti-fretting members 11 are respectively formed. The notch openings 9 and 10 have the same shape and are sized so that the anti-fretting member 11 can be inserted in any posture, and the rims of the front-side notch opening 9 and the back-side notch opening 10 are Positioning portions 13 and 13 for positioning the anti-fretting member 11 are formed. That is, even when the metal quadrangular prism 1 is used upside down, the anti-fretting member 11 can be positioned on the positioning portion 13. Note that the lip itself of the notch openings 9 and 10 may be adopted as the positioning portion 13.

  On both sides in the width direction at the peripheral edge portions of the notch openings 9 and 10, vertically long insertion holes 14 and 14 into which insertion fixing pieces of the movement restricting means 15 described later are inserted are formed.

  A movement restricting means 15 that restricts the movement of the anti-fretting member 11 from the positioning portion 13 of the notch openings 9 and 10 is attached to the metal square pole 1.

  The movement restricting means 15 includes a rectangular movement restricting portion 16 that restricts movement of the anti-fretting member 11 from the positioning portion 13 of the notch openings 9, 10, and a rear surface from both side end portions of the movement restricting portion 16. It is constituted by fitting and fixing pieces 17 and 17 which are integrally projected toward the side (in other words, the mouth edges of the cutout openings 9 and 10) and are inserted into the fitting insertion holes 14 and 14.

  Each of the insertion-fixing pieces 17 has a wedge shape that narrows toward the tip, and the vertical width of the base end portion 17 a is smaller than or substantially the same as the vertical dimension of the insertion-insertion hole 14. Each of the insertion and fixing pieces 17 is formed with an elastic piece 18 cut and raised outward. When the insertion and fixing piece 17 is inserted into the insertion hole 14, the elastic piece 18 The free end 18 is brought into contact with the inner surface of the rim of the insertion hole 14 and the insertion fixing piece 17 is fixed.

  Further, in the mounted state of the movement restricting means 15, a slight gap S is held between the movement restricting portion 16 and the anti-fretting member 11. In this way, even if a slight dimensional error has occurred in the movement restricting portion 16 in the anti-fretting member 11 or the movement restricting means 15, the movement restricting means 15 can be easily attached due to the presence of the gap S. The movement restriction of the anti-fretting member 11 can be reliably performed.

  Next, the case where the metal square column having the above-described configuration is used as a wall surface base material will be specifically described.

  First, as shown in FIG. 3, for example, U-shaped runners 19, 19 are arranged on the ceiling slab surface and the floor surface so that their open sides face each other.

  Next, the upper and lower ends of the plurality of metal square pillars 1, 1... Configured as described above are fitted into the upper and lower runners 19, 19, and the metal square pillars 1, 1. (Ie, in the direction of arrows A and B in FIG. 3) are built at predetermined intervals. If it does in this way, the board sticking surfaces 7 and 8 in each metal square pillar 1 will be located in parallel with the span direction of runners 19 and 19.

  Thereafter, the anti-fretting member 11 is successively inserted into the cutout openings 9 and 10 of the respective metal square pillars 1 and positioned at the positioning portion 13. Next, the insertion fixing pieces 17 and 17 in the movement restricting means 15 are inserted by finger force into the insertion insertion holes 14 and 14 formed in the front surface 5 and / or the back surface 6 of each metal square column 1. The movement restricting means 15 is attached. Then, each insertion fixing piece 17 is fixed by contact with the inner side edge of the insertion hole 14 of the elastic piece 18. In this state, movement of the anti-fluff member 11 from the positioning portion 13 is restricted by the movement restricting portion 16, and movement in the width direction is restricted by the positioning portion 13.

  When a plurality of pairs of cutout openings 9 and 10 are formed in the metal square pole 1, the above operation is repeated a plurality of times.

  When the anti-fretting member 11 is assembled as described above, the upward movement of the anti-fretting member 11 is restricted by the movement restricting part 16 in the movement restricting means 15 and the lateral movement is restricted by the positioning part 13. Thus, the metal square columns 1, 1... Are firmly connected to each other by the anti-fretting member 11. In this state, the metal square pillars 1, 1... Are completely prevented from being bent in the runner span direction and in the direction perpendicular to the runner span direction, and a solid wall base structure is finished.

  Thereafter, a board 20 for top bonding is stretched on one or both of the board pasting surfaces 7 and 8 using a dry wall screw (small screw), but the metal square pillars 1, 1. Since a robust wall surface base structure that is prevented from warping by securing the connectivity by the stopper member 11 is obtained, the board pasting operation can be performed very quickly and reliably.

  When the movement restricting means 15 is attached to the front surface 5 and the back surface 6 of the metal quadrangular prism 1, the cutout openings 9 and 10 have various shapes other than a rectangle (for example, a polygon such as a triangle, a rectangle, a hexagon, etc.). , Oval, etc.). Moreover, regardless of the shape of the cutout openings 9 and 10 and the cross-sectional shape of the anti-fretting member 11, the anti-fretting member 11 can be reliably fixed by only slightly changing the shape of the movement restricting means 15.

  In addition, as shown in FIG. 4, the anti-fretting member 11 may be inserted into the notch openings 9 and 10 so that the open side faces upward. Also in this case, the movement restriction of the anti-fretting member 11 by the movement restriction means 15 can be ensured.

Second Embodiment FIGS. 5 and 6 show a metal prismatic column with an anti-fretting device according to a second embodiment of the present invention.

  In this case, the positioning portion 13 is formed with an arc-shaped protrusion 13a that is pressed against the side surface of the anti-fretting member 11 during positioning. If it does in this way, positioning of anti-fretting member 11 can be performed more certainly. Since other configurations and operational effects are the same as those in the first embodiment, the description thereof is omitted.

Third Embodiment FIG. 7 shows a metal prismatic column with an anti-fretting device according to a third embodiment of the present invention.

  In this case, the metal quadrangular column 1 is formed by bending a metal plate cut into a predetermined width into a square cylinder shape so that both ends thereof are in contact with each other at a position near one corner of the four surfaces. At both ends of the plate, U-shaped bent portions 21 and 21 that are bent in a U-shape toward the inner side and the outer side of the quadrangular column 1 are provided. It is formed as a planar connection portion 22 that is continuous in the direction. Since other configurations and operational effects are the same as those in the first embodiment, the description thereof is omitted.

  In each of the above embodiments, the insertion holes 14 and 14 are formed in the periphery of the front-side and back-side cutout openings 9 and 10 in the metal quadrangular column 1, but in either one of the periphery. The insertion holes 14 may be formed.

  Further, in each of the embodiments described above, the anti-fretting member 11 is constituted by a member having a U-shaped cross section, but may have another shape (for example, an H-shaped cross section).
