JP 2006-266016 A JP 2008-82028 A

However, in the above prior art, since the tubular body is formed of a steel having a square hollow cross section, when the screw is inserted into the tubular body from the front surface of the wall surface or the crosspiece and the tubular body is attached to the wall surface or the crosspiece, the tubular body is formed. The screw head is exposed in front of the body. In order to prevent this, a connecting tool for connecting the tubular body to the wall surface or the like is required separately, which increases the number of parts and complicates the mounting structure to the building .

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a lattice and a connecting tubular body that can simplify a structure for mounting to a building .

Means for Solving the Problems and Effects of the Invention

In order to achieve this object, according to the tubular body for a lattice and the connecting element according to claim 1, a part of the steel plate material constitutes the attachment plate portion of the long first member. Both ends of a plate material that partially constitutes the mounting plate portion are bent, and a pair of standing plate portions are erected on both side edges in the longitudinal direction of the mounting plate portion. A mounting plate is attached to the building .

A part of the steel plate material constitutes the front plate portion of the long second member. Both ends of the plate material that partially constitutes the front plate portion are bent, and a pair of side plate portions are erected on both side edges in the longitudinal direction of the front plate portion. At least one of the side plate portion and the upright plate portion is joined to the other of the side plate portion and the upright plate portion by the joint portion, and the first member and the second member are tubular.

Therefore, after attaching the first member to the building with a screw or the like, the second member can be joined to the first member to form a tubular shape. Since the screw etc. which attach a 1st member to a building can be concealed with a 2nd member, and it is not necessary to prepare a connection tool, there exists an effect which can simplify the attachment structure to a building .

Further , the bent portion is formed by bending the joining portion so that the side edge portion in the longitudinal direction of the side plate portion overlaps the inner side surface of the side plate portion . A side edge portion in the longitudinal direction of the bent portion is folded to form a folded portion, and a side edge portion in the longitudinal direction of the folded portion is folded to the bent portion side to form a flange portion.

Upright plate portion, engaging portion is projected towards the upright plate portion you face. When the standing plate portion is inserted between the bent portion and the folded portion, the locking portion is locked to the collar portion, and the first member and the second member are joined. Therefore , the first member and the second member can be easily joined.

After joining , the side plate part and the bent part of the second member can be positioned outside the first member in the short direction. As a result, the side plate portion of the second member can be put on the standing plate portion of the first member, and the folded portion and the flange portion can be positioned in the hollow space of the first member and the second member. From the front side of the building, since the turned-back portion and the hook portion of the second member can be made invisible, there is an effect that can improve flourished seen. Lattice and runners can be easily provided in existing buildings.

According to the grating and for diad for tubular bodies according to claim 2, wherein the lid member is mounted on at least one end portion of the first member and the second member which is tubular by being joined at the junction. The lid member has a closing portion in contact with the shaft ends of the first member and the second member, and a press-fitting portion projects from the closing portion. Since the joining portion is cut off at the end portions in the axial direction of the folded portion and the flange portion by the notch portion, the interference between the folded portion and the flange portion and the press-fit portion is avoided, and the shaft ends of the first member and the second member The press-fitting part can be press-fitted into.

As described above, since the lid members are attached to the shaft ends of the first member and the second member, in addition to the effects of claim 1 , it is possible to prevent the entry of foreign matters such as dust and insects and to expose the edges of the shaft ends. There is an effect that can be prevented by the closing portion.

  Moreover, since there exists a notch part, the protrusion to the inner side of a folding | turning part and a collar part can be prevented, and it can prevent that the opening of the axial end of a 1st member and a 2nd member becomes small. When the opening becomes small, it becomes difficult to press-fit the press-fitting portion of the lid member. Therefore, when the notch portion is not provided, the shaft ends of the first member and the second member are placed outside in the direction perpendicular to the axis in order to secure the opening. It is necessary to expand to. If the shaft end is expanded outward in the axial direction, the linearity in the longitudinal direction of the first member and the second member will be impaired. However, the notch portion allows the press-fitting portion of the lid member to be press-fitted into the shaft end without expanding the shaft ends of the first member and the second member outward in the axial direction. There is an effect that the linearity of the direction can be secured.

Tube-shaped body 1 as shown in FIG. 2, the first member 10 and second member 20 formed by sheet metal working of metal plate, is mounted on the shaft end of the first member 10 and the second member 20 And a lid member 30. Since one end and the other end in the longitudinal direction of the first member 10 and the second member 20 are formed in the same shape, one end (upper part) in the longitudinal direction of the first member 10 and the second member 20 in FIG. The vicinity of the shaft end on the side is shown, and the other illustrations in the longitudinal direction are omitted.

As the plate material constituting the first member 10 and the second member 20, a plate material made of alloy steel such as steel, clad steel, stainless steel, etc .; a plate material made of non-ferrous metal such as aluminum, copper, zinc, titanium or the alloy thereof Galvanized steel plate such as PVC coated steel plate; Galvalume steel plate (registered trademark), which is a molten aluminum / zinc alloy plated steel plate; Painted plate material or the like is used.

A plate having a thickness of about 0.3 to 0.8 mm is used. In the present embodiment, the first member 10 and the second member 20 are made of the same material and the same plate thickness. The length and width of the plate is appropriately set by the size of the building B the tube-shaped body 1 is fixed (see FIG. 1). The plate material is bent by a press brake, a bender, a roll forming machine or the like, and is formed into a predetermined shape of the first member 10 and the second member 20. In particular, when formed by a press brake, it is preferable because undulation (meandering) in the longitudinal direction of the first member 10 and the second member 20 is suppressed as compared with the case of forming by a roll forming machine.

  The first member 10 is a member that is attached to the wall surface 40 (see FIG. 1) and supports the second member 20. As shown in FIG. 2, the first member 10 has a mounting plate portion 11 formed by a part of a vertically long rectangular plate member, and both ends of a plate member that partially forms the mounting plate portion 11 are bent at substantially right angles. Thus, the mounting plate portion 11 is configured to include a pair of standing plate portions 12 that are erected on both side edges 11a in the longitudinal direction. The mounting plate portion 11 and the upright plate portion 12 are both formed in a long rectangular shape, and the pair of upright plate portions 12 are disposed so as to face each other and be substantially parallel to each other. Thereby, the 1st member 10 is formed in cross-sectional U shape as a whole.

  As for the standing board part 12, the latching | locking part 13 is formed in the position near the side edge 12a. The locking portion 13 is a protrusion of the inner surface of the upright plate portion 12, and in this embodiment, a burr generated by punching from the outer surface of the upright plate portion 12 toward the inner surface and punching. It is formed by. Further, a plurality of the locking portions 13 are formed at predetermined intervals (about 20 cm in the present embodiment) along the side edge 12a.

  The second member 20 is a member for constituting a hollow section tubular body together with the first member 10 by being supported by the first member 10. The second member 20 includes a front plate portion 21 formed of a part of a vertically long rectangular plate member, and both ends of a plate member partially constituting the front plate portion 21 in a longitudinal direction of the front plate portion 21. A pair of side plate portions 22 erected on both side edges and a joint portion 23 formed on the side plate portion 22 are configured. Both the front plate portion 21 and the side plate portion 22 are formed in a long rectangular shape, and the pair of side plate portions 22 are disposed to face each other. Thereby, the front board part 21 and the side board part 22 are formed in a cross-sectional U-shape as a whole. The width in the short direction of the front plate portion 21 is set to be slightly larger than the width in the short direction of the mounting plate portion 11 of the first member 10.

  The joining portion 23 is a portion formed to join the upright plate portion 12 of the first member 10 and the side plate portion 22 of the second member 20, and is formed on the second member 20 in the present embodiment. Yes. The joint portion 23 is formed by bending a side edge portion in the longitudinal direction of the side plate portion 22 so as to overlap the opposing surfaces (inner side surfaces) of the side plate portions 22, and the longitudinal direction of the bent portion 24. The folded portion 25 is formed by folding the side edge portion, and the flange portion 26 is formed by folding the side edge portion in the longitudinal direction of the folded portion 25 toward the bent portion 24 side.

  The folded portion 24 is formed into a bag shape having a U-shaped cross section integrally with the folded portion 25 by coupling the folded portion 25. The pair of bent portions 24 bent to the inner side of the side plate portion 22 is set so that the distance between the opposed bent portions 24 becomes narrower as the distance from the front plate portion 21 increases. That is, the distance between the bent portions 24 is minimized at the farthest part of the bent portion 24 from the front plate portion 21. The upright plate portion 12 of the first member 10 is inserted into the bag-shaped portion formed by the bent portion 24 and the folded portion 25, and the side edge 12 a of the inserted upright plate portion 12 is bent at the bent portion 24. (See FIG. 3 (b)).

  The collar portion 26 is a portion that functions to prevent the standing plate portion 12 (the locking portion 13) from coming off, and the tip is bent toward the front plate portion 21 side. As a result, when the standing plate portion 12 is inserted between the bent portion 24 and the folded portion 25, the folded portion 25 and the flange portion 26 are elastically deformed to protrude from the standing plate portion 12. The stop 13 can pass through the collar 26. On the other hand, after the locking part 13 passes through the collar part 26, the locking part 13 is caught on the edge of the collar part 26 (see FIG. 3B). Therefore, in the standing plate part 12 inserted between the bent part 24 and the folded part 25, the side edge 12 a comes into contact with the bottom part 24 a of the bent part 24, and the locking part 13 is caught on the edge of the flange part 26. By this, it fixes to a transversal direction (FIG. 3A left-right direction).

  Further, the bent portions 24 are set so that the distance between the bent portions 24 facing each other becomes narrower as the distance from the front plate portion 21 increases. Therefore, the side plate portions 22 and the folded portions are formed outside the standing plate portion 12. When the curved portion 24 is covered, the standing plate portion 12 is elastically deformed so as to narrow the interval between the pair of side plate portions 22 and the bent portion 24. As a result, since the friction between the bent portion 24 and the upright plate portion 12 can be increased, the second member 20 is displaced in the longitudinal direction (the vertical direction in FIG. 3A) with respect to the first member 10. Can be prevented.

  The second member 20 includes a notch portion 27 in which the shaft end folded portion 25 and the flange portion 26 are notched in the joint portion 23. The notch 27 is a part for avoiding interference with the lid member 30 attached to the shaft ends of the first member 10 and the second member 20. The lid member 30 is a synthetic resin or metal member that is attached to the tubular shaft ends of the first member 10 and the second member 20 that are joined to each other, and is attached to the shaft ends of the first member 10 and the second member 20. It is configured to include a closing portion 31 that abuts and closes the opening, and a press-fit portion 32 that protrudes from the closing portion 31.

Referring now to FIG. 3 (a), it will be described the construction method of the tube-shaped body 1. In the present embodiment, the case of applying a tube-shaped body 1 to the wall 40 fixed to the precursor 42 (siding) through the base member 41. First, the mounting plate portion 11 of the first member 10 is brought into contact with the wall surface 40, and the screw 43 is screwed from the mounting plate portion 11 through the wall surface 40 and the base material 41 to the housing 42, so The member 10 is fixed. Next, the second member 20 is struck so that the bent portion 24 of the second member 20 is placed on the standing plate portion 12 of the first member 10, and the standing plate is interposed between the bent portion 24 and the folded portion 25. Insert the part 12. The second member 20 is fixed to the first member 10 by the standing plate portion 12 abutting on the bottom portion 24a and the hook portion 26 being hooked on the locking portion 13, and the first member 10 and the second member 20 as a whole. Tubular.

  As described above, since the second member 20 is joined to the first member 10 by the joint portion 23 after the first member 10 is attached to the wall surface 40 with the screws 43, the screws 43 that attach the first member 10 to the wall surface 40. Can be concealed by the second member 20. Since the screw 43 cannot be seen by the second member 20, the appearance can be improved. In addition, since a connecting tool or the like for fixing to the wall surface 40 is not required, the number of parts can be reduced and the mounting structure to the wall surface 40 can be simplified. Furthermore, since the 1st member 10 and the 2nd member 20 can be fixed from the front surface of the wall surface 40, the attachment workability | operativity to the wall surface 40 can be improved. Therefore, it is possible to easily provide a lattice or a contiguous member in the existing building B.

  Further, by fitting the upright plate portion 12 of the first member 10 inside the side plate portion 22 and the bent portion 24 of the second member 20, the locking portion 13 is caught by the flange portion 26 and the second member 20. Is fixed to the first member 10. Since the second member 20 is struck (inserted) into the first member 10 only once, the mounting workability can be improved.

  Further, since the joint portion 23 is formed on the second member 20, the side plate portion 22 and the bent portion 24 of the second member 20 can be positioned outside the standing plate portion 12 of the first member 10. . As a result, the side plate portion 22 of the second member 20 is placed on the standing plate portion 12 of the first member 10, and the folded portion 25 and the flange portion 26 are placed in the hollow space of the first member 10 and the second member 20. Can be positioned. Although the side plate portion 22 and the standing plate portion 12 can be visually recognized from the front side of the wall surface 40, the folded portion 25 and the flange portion 26 of the second member 20 can be made invisible, so that the appearance can be improved.

Since the side plate part 22 (second member 20) and the standing plate part 12 (first member 10) can be made visible from the front side of the wall surface 40, the first member 10 and the second member 20 are made different colors. As a result, the freedom of color arrangement can be improved. In particular, in the opening such as entrance or window, in the case of using the tube-shaped body 1 as application of a screen or blind, by a first member 10 and the second member 20 in different colors, external (second member The impression received from the (20 side) and the impression received from the inside (first member 10 side) can be made different, which is preferable.

Next, the mounting structure of the lid member 30 will be described with reference to FIG. Figure 3 (c) is a sectional view of the shaft end in the longitudinal direction of the tube-shaped body 1 the lid member 30 is attached. As shown in FIG. 3C, the closing portion 31 of the lid member 30 is a portion for closing the opening of the shaft end of the joined first member 10 and second member 20, and the first member 10 and The shape and size are set to be approximately the same as the tubular shaft end formed by the second member 20.

  The press-fit portion 32 includes a base portion 33 that is press-fitted into a tubular shaft end formed by the first member 10 and the second member 20, a shaft portion 34 that protrudes in the axial direction of the base portion 33, and a shaft of the shaft portion 34. A plurality of ridge-shaped projecting portions 35, 36, and 37 projecting outward in the straight direction are provided. The base portion 33 and the overhang portions 35 and 36 are portions whose outer circumferences are pressed against the inner wall surfaces of the first member 10 and the second member 20. Since the base portion 33 and the overhang portions 35 and 36 are provided to be spaced apart from each other in the axial direction of the shaft portion 34, the shaft portion 34 is supported at a plurality of locations in the axial direction of the first member 10 and the second member 20. Is done. As a result, it is possible to prevent the cover member 30 attached to the shaft end from rattling.

  Further, since the overhang portions 35 and 36 are projected in the shape of ridges on the axially outer side at a plurality of locations in the axial direction of the shaft portion 34, sealing performance can be secured, and the first member 20 and Infiltration of rainwater or the like from the gap between the second member 20 and the lid member 30 can be suppressed. Furthermore, since the shaft end is covered by the closing portion 31, it is possible to prevent foreign matter such as dust and insects from entering from the opening and to prevent the edge of the shaft end from being exposed. Therefore, even if the edges of the shaft ends of the first member 10 and the second member 20 are sharp, the risk of being cut by the closing portion 31 can be eliminated.

  Further, since the shaft ends of the folded portion 25 and the flange portion 26 are notched by the cutout portion 27, the inner ends of the folded portion 25 and the flange portion 26 are prevented, and the shaft ends of the first member 10 and the second member 20 are prevented. Can be prevented from becoming smaller. When the opening becomes small, it becomes difficult to press-fit the press-fitting portion 32 of the lid member 30. Therefore, when the notch 27 is not provided, the shaft ends of the first member 10 and the second member 20 are secured in order to secure the opening. Needs to be expanded outward in the axial direction. If the shaft end is expanded outward in the axial direction, the linearity in the longitudinal direction (axial direction) of the first member 10 and the second member 20 is impaired. However, the cutout portion 27 allows the press-fit portion 32 of the lid member 30 to be press-fit into the shaft end without expanding the shaft ends of the first member and the second member outward in the axial direction. The linearity in the longitudinal direction of the two members 20 can be ensured.

  The bent portion 24 of the second member 20 is the farthest from the front plate portion 21 (the boundary between the bent portion 24 and the folded portion 25), and the distance between the opposed bent portions 24 is minimized. Is set to Further, since the rigidity of the bent portion 24 is improved by providing the folded portion 25, when the standing plate portion 12 is inserted between the folded portion 24 and the folded portion 25, the standing plate portion 12 is The bent portion 24 is pushed from the outside and is elastically deformed so as to narrow the interval therebetween. As a result, the press-fit portion 32 (base portion 33 and overhang portions 35, 36) of the lid member 30 is sandwiched by the standing plate portion 12 from both sides. Since the base portion 33 and the overhang portions 35 and 36 of the lid member 30 are fastened to the standing plate portion 12, the lid member 30 in which the press-fit portion 32 is press-fitted into the shaft end can be made difficult to come off.
