Description

  The present invention relates to an insertion fitting to be inserted into a through hole of a hollow rod-shaped building material.

  In some cases, vertical walls are erected along the outer wall of the building, and ceramic rod-shaped building materials are installed in the horizontal direction between the vertical walls to construct school-style walls and louvers.

  When the outer wall of the building is tiled, a ceramic rod-shaped building material that matches the tiles and has excellent weather resistance is used. In addition, since ceramic is a material that may break, there is a risk of breaking and falling when a ceramic rod-shaped building material is installed horizontally. Therefore, the ceramic rod-shaped building material is made hollow with a through hole penetrating in the longitudinal direction, a metal rod-shaped body (bar) is inserted into the through hole, and both ends of the bar are fixed with bolts in a vertical manner. Therefore, a mounting structure configured to hold the hollow bar-shaped building material in a vertical position via the bar is widely adopted (for example, Japanese Patent Application Laid-Open No. 2004-19220).

  With such a mounting structure for a hollow bar-shaped building material, even if the bar-shaped building material is broken, the bar-shaped building material is prevented from falling.

  4 is an exploded perspective view of the mounting structure for hollow building materials disclosed in the publication, FIG. 5 is a horizontal sectional view of the mounting structure for hollow building materials, and FIG. 6 is a sectional view taken along the line VI-VI in FIG.

  A ceramic hollow rod-shaped building material 1 is attached to a T-shaped steel 3 constituting a vertical by lateral pulling with a square bolt 4 via a bar 2. The bar 2 is inserted through the through hole 5 of the rod-shaped building material 1. In addition, bolt insertion holes 6 are provided in the vicinity of both ends of the rod-shaped building material 1 so as to penetrate the wall surface on the T-shaped steel 3 side.

  The bar 2 has a horizontal piece 7 arranged along the ceiling surface of the through-hole 5 and a long side of the horizontal piece 7 on the T-type steel 3 side along the wall surface of the through-hole 5 on the T-type steel 3 side. It is comprised from the drooping piece 8 bent at right angle toward the downward direction. Bolt insertion holes 9 are provided near both ends of the hanging piece 8 so as to overlap the bolt insertion holes 6 of the rod-shaped building material 1. Convex steps 10 and 11 are formed in the vicinity of both ends of the upper surface of the horizontal piece 7 and the side surface of the hanging piece 8, respectively.

  The T-shaped steel 3 includes a main piece 3a to which the rod-shaped building material 1 is attached and constructed, and a rib piece 3b that protrudes from the back side of the main piece 3a. The main piece 3a is provided with a pair of left and right bolt insertion holes 12, 12 sandwiching the rib piece 3b at a predetermined interval in the vertical direction.

  Bolts are inserted into the bolt insertion holes 9, 6, and 12 so as to penetrate the hanging piece 8 of the bar 2, the wall surface on the T-shaped steel 3 side of the bar-shaped building material 1, and the main piece 3 a of the T-shaped steel 3 from the inside of the through hole 5. The bolt-shaped building material 1 is fixedly attached to the T-shaped steel 3 via the bar 2 by inserting the four bolt shafts 4a and tightening the nuts 13 into the bolt shafts 4a.

  When the bolt shaft 4 a of the bolt 4 is inserted into the bolt insertion hole 9, the square columnar portion 4 b engages with the edge portion of the bolt insertion hole 9, and the bolt shaft 4 a is not rotatable in the bolt insertion hole 9. Will be held in.

  A metal wire 15 extends from the tip end side of the bolt shaft 4a. By inserting the metal wire 15 into the bolt insertion holes 6 and 9 through the openings of the through holes 5 and pulling the metal wires 15 toward the T-shaped steel 3, the bolt shaft 4 a is drawn into the bolt insertion holes 6 and 9. The metal wire 15 is further drawn through the spacer 14 and the bolt insertion hole 12 and pulled to the back side of the main piece 3 a of the T-shaped steel 3, whereby the bolt shaft 4 a is inserted into the spacer 14 and the bolt insertion hole 12. Thereafter, the metal wire 15 is unwound from the bolt shaft 4a, and the nut 13 is fastened to the bolt shaft 4a.

  The bar 2 (insertion bracket) is a single piece having a length similar to that of the rod-shaped building material 1, but such a single bar 2 is accurately cut according to the length of the rod-shaped building material 1. Since the hole 9 is made by drilling, it takes time and effort.

FIG. 4 of Japanese Patent Application Laid-Open No. 2002-256651 shows an insertion metal fitting formed by welding holding metal fittings to both ends of a square pipe.
JP 2004-19220 A JP 2002-256651 A

  In the above-mentioned add-on type insertion fitting disclosed in JP-A-2002-256651, the holding fitting is brought into contact with the end surface of the square pipe and both are welded together. The cutting length of the square pipe needs to be a specified value with high accuracy. Moreover, it is necessary to make the cut surface of a square pipe exactly orthogonal to the longitudinal direction. Furthermore, it is necessary to perform welding while aligning both surfaces so that the surface of the square pipe and the surface of the holding metal fitting are parallel. For this reason, not only the insertion fitting disclosed in Japanese Patent Application Laid-Open No. 2004-19220 but also the insertion fitting disclosed in Japanese Patent Application Laid-Open No. 2002-256651 are time-consuming. In addition, because of this, there is a possibility that the production of the insertion metal fitting may not be in time when orders increase rapidly.

  An object of the present invention is to solve the above-mentioned conventional problems and to provide an insertion fitting for a bar-shaped building material that is easy to manufacture.

An insertion fitting for a rod-shaped building material of the present invention (Claim 1) is a rod-shaped insertion fitting inserted into the through-hole of a rod-shaped building material having a through-hole penetrating in the longitudinal direction, and a plurality of parts are joined together. in the insertion fitting comprising rod-like building materials, parts of said plurality of the end parts are respectively arranged at each end of the insertion fitting consists of a main part that is disposed between these end parts, said end parts at both ends of the insertion payment instrument The end parts are overlapped and joined to the upper surface of the main part such that the end parts come into contact with the ceiling surface of the through hole .

According to a second aspect of the present invention, there is provided an insertion fitting for a rod-shaped building material according to the first aspect, wherein an opening is provided on the end portion side of each end part in the longitudinal direction of the insertion fitting.

  The rod-shaped building material insertion bracket according to claim 3 is the rod-shaped building material insertion bracket according to claim 2, wherein the main part and the end part have an L-shaped cross-section in a direction perpendicular to the longitudinal direction of the insertion bracket, and the corner part of the end part is the main part. It is overlapped and joined to the convex corners, and the openings are provided in the two crossing surfaces of the L-shaped end parts, and each opening is inserted from the end of the main part of the end parts. It is provided in the part extended in the longitudinal direction.

  The rod-shaped building material insertion fitting of the present invention is formed by connecting a plurality of parts, and the ends of the parts are overlapped and joined. Therefore, the total length of the insertion fitting can be adjusted to the specified length by adjusting the overlap allowance between the parts. For this reason, manufacture of this insertion metal fitting becomes easy.

  When the insertion fitting is composed of a main part and end parts at both ends thereof, it is preferable to provide an opening on the distal end side in the insertion fitting longitudinal direction of each end part. This opening is for insertion of a bolt or the like for fixing the insertion fitting. If the opening is shifted to the tip end side in this way, the overlap margin between the main part and the end part becomes large, and the length adjustment range of the insertion fitting becomes large.

  If the main part and the end part have L-shaped cross sections in the direction perpendicular to the longitudinal direction of the insertion bracket, join the two parts so that the corners of the end parts overlap the convex corners of the main part. It is preferable. This ensures that the surfaces of the main part and end part are parallel. Moreover, the upper surface of the both ends of an insertion bracket becomes high by the thickness of an end part.

  In this case, it is preferable to configure each of the two orthogonal surfaces of the end part so that the opening does not overlap the main part. Thereby, it becomes possible to use an insertion metal fitting so that it may insert into a rod-shaped building material so that either of two surfaces of an L-shaped insertion metal fitting may face upward.

The main part 30 has a first piece 31 and a second piece 32 which are orthogonal to each other. The end part 40 has a first piece 41 and a second piece 42 which are orthogonal to each other. Each of the first piece 41 and the second piece 42 is provided with an opening 43 made of a long hole extending in the longitudinal direction of the insertion fitting 20. The opening 43 is arranged closer to the distal end side of the insertion fitting 20 than the middle of the end part 40 in the longitudinal direction.

  The end parts 40, the intersection corners of the first piece 41 and the second piece 42 of the end part 40 are brought into contact with the intersection convex corners of the first piece 31 and the second piece 32 of the main part 30. 40 is superimposed on both ends of the main part 30 and fixed by spot welding.

  In FIG. 2, “t” indicates an overlap of the end part 40 and the main part 30.

  This insertion fitting 20 is used in the same manner as the parts shown in FIGS. That is, the insertion fitting 20 is inserted into the through-hole 5 of the hollow rod-shaped building material 1 and fixed in a vertical manner via the bolt.

  In this embodiment, the total length of the insertion fitting 20 can be adjusted by adjusting the overlap allowance t between the end part 40 and the main part 30, and an insertion fitting having a specified length can be easily manufactured. Can do. In this embodiment, since the opening 43 is offset toward the tip side of the end part 40, the adjustment range of the overlap allowance t is large.

  Further, in this insertion fitting 20, the main part 30 and the end parts 40, 40 are easily positioned because the two orthogonal pieces 31, 32, 41, 42 are overlapped with each other. The metal fitting 20 can be easily manufactured.

  In this embodiment, as shown in FIG. 3, the second piece 42 of the end part 40 fixed to both ends of the main part 30 is superimposed on the upper surface of the second piece 32 of the main part 30. At both ends, the second piece 42 of the end part 40 is higher than the second piece 32 of the main part 30 by the thickness of the second piece 42. Therefore, even when the rod-shaped building material 1 is warped in a hanging shape as shown in FIG. 3, the second pieces 42 and 42 on both end sides of the insertion fitting 20 can be brought into contact with the ceiling surface of the through hole 5. The rod-shaped building material 1 is supported by the insertion fitting 20 without rattling.

  In this embodiment, since the insertion fitting 20 has an L-shaped cross-sectional shape, the second pieces 32 and 42 face upward as shown in FIGS. 1 (b) and 3, and the first pieces 31 and 41 are on the back side of the page.
