BACKGROUND OF THE INVENTION
The present invention relates to a construction lumber connecting bracket for connecting a pillar and a horizontal member, for example, when a horizontal member such as a beam is bridged over the pillar.
[0002]
[Prior art and problems to be solved by the invention]
Broadly speaking, there are two types of construction lumber connecting brackets (joint fittings): one with a U-shaped flat support or two with a T-shaped support, and one with a T-shaped support. It is used properly with its characteristics, and the precuts on the wood side to be connected are processed according to each.
[0003]
In this two-sheet support structure, for example, a plate material is bent into a U-shape or a U-shape, and a bolt through which a connection bolt that passes through a bolt through-hole provided in one wood is inserted into the folded portion. A hole is provided, and the opposite bent free end side (two support plate parts) is connected so that it can be connected (inserted and secured with a through bolt) to one of the lumber parts formed by pre-cutting. The structure is provided with a mouth connecting portion, and the two support plate portions of the metal fittings connected and fixed to one piece of wood are connected and fixed by engaging the joint portion of the other piece of wood. It is the structure connected with a metal fitting.
[0004]
In the case of a single-sheet support structure, the mounting plate portion provided with the bolt hole of the T-shaped base is connected and fixed to one piece of wood in the same manner, and the single supporting plate portion protruding from the mounting plate portion is provided. It is configured to engage and fix the other lumber joint, and to connect the woods in the same manner.
[0005]
In this way, for example, several pillar through holes that penetrate several connecting bolts are formed in a pillar that is one wood, and the bolt hole that communicates with the bolt through hole is, for example, Design Registration No. 886906. As in Design Registration No. 1064380, the U-shaped or U-shaped two-sheet support structure is located at the center of the bending width.
[0006]
However, in the case of a single-sheet support structure, for example, as in Design Registration No. 647891, Design Registration No. 1019532 or the like, the two pieces (separate plate materials) of the mounting plate portion and the support plate portion are joined together by welding, for example, design registration As shown in No. 979220 or the like, two symmetrical plates are laminated together like back to back.
[0007]
However, such a single-sheet support structure has many processing steps and is expensive.
[0008]
For this reason, for example, there is a configuration in which the support plate portion is bent and formed with respect to the mounting plate portion by bending from a single plate material, such as design registration No. 1019705 and design registration No. 1033225. The bolt hole for connecting and fixing to the pillar must be formed not on the center position but on the mounting plate part that is bent and protruded on one side or both right and left sides of the support plate part. Thus, the bolt hole cannot be formed at the metal center position.
[0009]
For this reason, since the bolt hole is shifted to one side with respect to the support plate of the center, there is a possibility that the strength may be reduced, and when using a two-sheet support structure for this wood, Since the position of the bolt through-hole through which the column passes is different in the case where it is adopted, the bolt through-hole must be formed at a different position depending on the metal fitting to be used, and a common precut cannot be made.
[0010]
The present invention finds such a problem and solves this, and is not configured to weld another piece by welding, but is configured to bend one of the support structure from one plate material, As with the two-bottle support structure, the center position of the metal fitting, that is, the base end edge of the support plate portion, in other words, the length direction (length extension) of the bent support plate portion is formed. It is not necessary to change the position of the bolt through-holes of the connecting bolts provided on the wood in any of the metal fittings, for example, in the case of a single support plate part. If it is processed so that it can be selectively engaged even in the case of the support plate part of the wood, it is a single piece support structure wood with a bolt hole at a very innovative center position that makes it possible to use both brackets with almost the same pre-cut The purpose is to provide connecting brackets .
[0011]
[Means for Solving the Problems]
The gist of the present invention will be described with reference to the accompanying drawings.
[0012]
A timber connection bracket made of a single plate material for connecting one building wood 1 and the other building wood 3 provided with a joint 2 at the end in a right angle or inclined state, A cut edge 4 for cutting and raising is formed on a sheet of plate material, and a support plate portion 6 is bent about 90 degrees with respect to the attachment plate portion 5 via the cut edge 4. 5 is provided with a bolt hole 9 which is in contact with the one building wood 1 and through which a connecting bolt 8 is inserted through a bolt through hole 7 provided in the building wood 1, and the bent support plate portion. 6 is provided with a joint connecting portion 10 connected to the joint portion 2 provided on the other building wood 3, and the length direction of the bent edge 11 of the bent base portion of the support plate portion 6 is the mounting plate. The position of the cutting edge 4 is set so as to be located at the center of the part 5, and the mounting plate part 5 substantially matches the length direction of the bent edge 11. Those of the connecting fitting timber, characterized in that arranged the bolt holes 9 in the central portion.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention (how to carry out the invention) considered to be suitable will be briefly described with reference to the drawings, showing its effects.
[0014]
The incision edge 4 is formed on one plate. For example, when a plate material having a predetermined shape is punched and formed, a cut portion is also formed and raised at a predetermined position of the plate material to form the cut edge 4 for bending.
[0015]
The support plate portion 6 is raised with respect to the mounting plate portion 5 by using the cut edge 4 to be bent.
[0016]
At this time, according to the present invention, the setting of the cutting edge 4 does not have a shape in which the mounting plate part 5 bends and protrudes to the side of the support plate part 6, but the folding which is the base edge of the support plate part 6. The length direction (length extension direction) of the curved edge 11 is located at the center of the mounting plate portion 5.
[0017]
That is, for example, by forming a bolt hole 9 in the central portion of the mounting plate portion 5 in advance, the bolt hole 9 is positioned in the length direction of the bent edge 11 of the support plate portion 6.
[0018]
Therefore, the base metal edge length direction of the support plate portion 6 as the center position, i.e., the one-piece support structure wood connecting bracket in which the bolt hole 9 is arranged at the center position together with the support plate portion 6, It can be formed by bending from a single plate material without a two-piece welded structure.
[0019]
Therefore, this bent structure can be easily manufactured by simple press working, etc., is excellent in mass productivity, does not increase the cost, and has a bent structure. Since the bolt hole 9 provided in the mounting plate portion 5 can be arranged in the base edge length direction of the portion 6, the two support plate portions 6 having a U-shaped cross section or U shape provided at the center position are similarly provided. Whether using a two-piece support structure of wood jointed in parallel or using a single-piece support structure of the main part, both can be provided by providing bolt through-holes 7 at predetermined positions on one piece of wood 1 (post). Both can be used and a common precut is sufficient.
[0020]
That is, for example, the joint portion 2 of the other wood 3 (horizontal material) is pre-cut so that it can be selectively inserted and engaged with either the two support plate portions 6 or the single support plate portion 6. If it is formed, the bolt through hole 7 on the pillar 1 side may be provided at the center position. If necessary, this pre-cut can also be used for a single metal support structure of the present invention even with a double metal support structure. This is an epoch-making wood connection fitting that can be appropriately adopted even with a wood connection fitting.
[0021]
【Example】
Specific embodiments of the present invention will be described with reference to the drawings.
[0022]
The present embodiment is configured as a connecting metal fitting for connecting the pillar 1 which is one building wood 1 and the horizontal member 3 such as a beam which is the other building wood 3. The connecting bracket having the single-sheet supporting structure of the embodiment or the connecting bracket having the two-sheet supporting structure as shown in FIG. 11 is pre-cut so that it can be used.
[0023]
The pillar 1 is formed with a plurality of bolt through holes 7 through which the connecting bolts 8 are inserted and fixed to the nuts 8 </ b> A in a plurality of center positions, and a single support plate 6 at the center position is also provided at the tip of the horizontal member 3. The two support plate portions are also formed so as to form the joint portion 2 that can be inserted and engaged, and are connected and fixed by the through pin 12.
[0024]
Therefore, in the present embodiment, the same pre-cut as in the case of the two-sheet support structure is provided by providing the bolt hole 9 in communication with the bolt through hole 7 at the center position as in the two-sheet support structure as shown in FIG. It is configured so that it can be used.
[0025]
That is, a cut edge 4 for cutting and raising is formed on a single plate material, and the support plate portion 6 is bent about 90 degrees with respect to the mounting plate portion 5 through the cut edge 4. The position of the cut edge 4 is set so that the length direction of the bent edge 11 of the bent base portion of the support plate portion 6 is located at the center of the mounting plate portion 5, and the length of the bent edge 11 is set. The bolt hole 9 is disposed at the center of the mounting plate 5 that substantially matches the vertical direction.
[0026]
Specifically, when a single plate material is cut into a predetermined shape by pressing, a locking hole 13 penetrating the bolt hole 9 and the through pin 12 is formed by punching and a cut portion is formed at a predetermined position. Thus, the cut edge 4 is formed.
[0027]
The cut edge 4 is set so that the bent edge 11 that raises the support plate portion 6 at a right angle by using the cut edge 4 is aligned with the bolt holes 9 on the bent edge 11 line.
[0028]
For example, in the first embodiment shown in FIGS. 1 to 4, the bolt holes 9 are formed in two places of the mounting plate portion 5, but the notches are formed so as to face the vertical positions of the bolt holes 9. (Because there is a plate edge on one side at the end, a notch is formed so as to face one side of the bolt hole 9), and the mounting plate 5 is formed so as to be cut out. By using the cutting edge 4 to raise the parallel direction of the bolt hole 9 as the bent edge 11, the support plate portion 6 is formed upright with respect to the mounting plate portion 5 provided with the bolt hole 9 in the center portion. The bolt holes 9 are juxtaposed on the extension line of the bent edge 11, and the bolt holes 9 are located in the length direction of the base end edge of the raised support plate portion 6, together with the support plate portion 6. The bolt hole 9 is disposed at the center position.
[0029]
Therefore, if the mounting plate portion 5 is simply bent and protruded on one side of the support plate portion 6, the mounting plate portion 5 is always located at a position shifted to one side of the support plate portion 6, and a bolt hole 9 for the mounting plate portion 5 is provided. However, in the present embodiment, for example, as described above, by simply setting the shape and position of the cutting edge 4, the support plate portion 6 is simply bent with respect to the mounting plate portion 5, A single metal support structure can be formed, and the support plate portion 6 is bent with respect to the center portion of the attachment plate portion 5, and the bolt hole 9 in the center portion of the attachment plate portion 5 is positioned at this center. It can form in a center position similarly to the support plate part 6 to perform.
[0030]
Therefore, if a large number of bolt through holes 7 provided in the pillar 1 are formed at the center position assuming a necessary number or various metal fittings, a common pre-cut is not required to be formed in the pillar 1 each time. The pre-cut is not limited to the one-sheet support structure or the two-sheet support structure, and can be used.
[0031]
Further, the second embodiment shown in FIGS. 5 to 7 is a case where a large number of bolt holes 9 are formed in a large number of separated portions of the mounting plate portion 5, respectively, and the third embodiment shown in FIGS. Shows a case where two bolt holes 9 are formed in a separated portion of the mounting plate portion 5 to be cut out.
[0032]
Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
[0033]
【The invention's effect】
Since the present invention is configured as described above, it is not a configuration in which separate pieces are joined by welding, but a configuration in which a single-sheet support structure is bent from a single plate material, but a two-bottle support structure is provided. The center position of the metal fitting, that is, the base end edge of the support plate portion, in other words, the bending direction of the bent support plate portion in the length direction (length extension direction). It is not necessary to change the position of the bolt through hole of the connecting bolt provided in the wood in any case, for example, in the case of one support plate part or two support plate parts. If it is processed so that it can be selectively engaged, it will be a one-piece support wood connection fitting with a bolt hole at a very innovative center position where both fittings can be used with almost the same pre-cut.
