JP3618308B2 - Upper column and lower column joining device - Google Patents

Description

[0001]
[Industrial application fields]
The present invention relates to an apparatus for joining an upper column and a lower column in a wooden building.
[0002]
[Prior art]
To set up the upper column on the lower column via a horizontal member (such as a beam), fit and join the tenon provided on the end face of each column to the tenon provided on the horizontal member side, In general, the lack of joint strength is compensated for by using different muscles or gargles.
[0003]
[Problems to be solved by the invention]
Since the conventional example employs a configuration in which the upper column and the lower column are joined via a horizontal member, the upper column and the lower column do not integrally move (vibrate) like a through column when an external force is applied. Therefore, the proof stress is not always satisfactory.
[0004]
The present invention was devised for the purpose of providing a joining device having excellent strength in such a manner that an upper column and a lower column can move as much as possible in response to an external force load.
[0005]
[Means for Solving the Problems]
A hardware substrate having a T-shaped mounting hardware configured by connecting a joining plate to the hardware substrate is superimposed on the upper surface of the lower pillar through a long hole provided in the gap material, and the slit is provided in the lower pillar. The joint plate inserted through the gap material is fixed to the lower column by a fixing rod, and the bolt rod of the bolt metal fitting whose base is fitted to the gap material is placed on the lower column through the metal substrate. And a metal fitting formed by placing a bonding plate upright on the metal substrate and inserted into the metal substrate placed on the horizontal member, screwing a nut and tightening it to the lower column, and engaging the nut. The upper column that is erected on the horizontal member through the combined spacer and the joining plate that is inserted into the upper column through a long hole provided in the spacer are fixed to each other with a fixing rod.

The drawings show an embodiment of the upper and lower column joining apparatus according to the present invention, FIG. 1 is a longitudinal sectional view, FIG. 2 is a central longitudinal sectional view of FIG. 1, FIG. 3 is an exploded perspective view, and FIG. FIG. 5 is a perspective view of the gap material, and FIG. 6 is a perspective view of the bolt hardware.
[0007]
The apparatus according to the embodiment includes a joint metal 1A and a mounting metal 1B having the same shape, a spacer 2A, a gap material 2B, and a pair of bolt hardware 3 and 3 having the same shape as the main members. The lower pillars 6 are joined to each other.
[0008]
Note that the joint metal 1A and the mounting metal 1B have the same shape in order to reduce both inventory costs and the like by using a single type of member, and there is no inconvenience in explanation. For example, the hardware substrate 11) has the same name. This also applies to the relationship between the spacer 2A and the gap material 2B.
[0009]
Further, in the embodiment, the mortise 7 is provided in the horizontal member 4 and the tenon 8 provided on the other horizontal member 4 ′ arranged in the direction orthogonal to the horizontal member 4 is fitted to the horizontal member 4. 4 and 4 'are joined together, but the other horizontal member 4' may be omitted (thus, the mortise 7 of the horizontal member 4 is omitted).
[0010]
The metal fitting 1A and the fitting metal 1B are provided with a bonding plate 12 in the center between the through holes 10 and 10 on one side of the metal substrate 11 provided with a pair of through holes 10 and 10 into which the bolt rod 9 of the bolt metal 3 is inserted. It is formed by connecting (standing) the metal substrate 11 in a perpendicular direction to form a T-shaped cross section, and the joining plate 12 is provided with a pair of through holes 14 and 14 for penetrating the drift pin 13. is there.
[0011]
The spacer 2A and the gap member 2B are made of a hard synthetic resin, and the joint plate 12 (of the joint metal 1) is located at the center of one side of the rectangular main plate 15 that coincides with the cross-sectional squares of the upper and lower columns 5 and 6. A long hole 16 penetrating through the bolt is provided, and the left and right equidistant intervals around the long hole 16 coincide with the rectangular base portion (head portion) 17 of the bolt hardware 3, 9 is provided with a through hole 19 that engages with a nut 18 screwed into the nut 9.
[0012]
The bolt hardware 3 is configured by projecting a bolt rod 9 on the base portion 17.
[0013]
Further, the end of the upper and lower pillars 5 and 6 is fitted with the slit 20 for inserting the joining plate 12 of the joining hardware 1A or the mounting hardware 1B and the drift pin 13 across the slit 20 by precut processing. A pair of through holes 21 and 21 to be inserted are formed.
[0014]
Accordingly, the base member 17 of the gap member 2B is polymerized by fitting the base portion 17 into the through hole 19 on the end (upper) surface of the lower column 6 and superposing the pair of bolt metal members 3 and 3 together. The projecting bolt rod 9 is inserted into the through hole 10, and the joining plate 12 is inserted into the slit 20 through the long hole 16, and the metal substrate 11 of the mounting hardware 1B is lowered through the gap material 2B. When superposed on the end face of the column 6 and a drift pin (which can be fixed with a housing) 13 is driven into the through hole 21 through the through hole 14, the mounting metal 1B, the gap member 2B and the bolt metal are inserted into the lower column 6. 3 is assembled, and a pair of bolts 9 and 9 (bolts) project from the lower column 6.
[0015]
A horizontal member that passes through the bolts 9 and 9 through a pair of through-holes 22 and 22 provided in advance so as to coincide with the interval width of the bolts 9 and 9 (and the mortise 7 described above). When 4 is placed on the lower pillar 6 via the metal substrate 11, the horizontal member 4 is temporarily fixed (placed) on the lower pillar 6 by the engagement relationship between the through hole 22 and the bolt rod 9. In this state, as described above, the other horizontal member 4 ′ is combined with the horizontal member 4 so that the tenon 8 is engaged with the tenon hole 7 and protrudes from the horizontal member 4 through the through hole 22. The metal base 11 of the joint metal 1A is placed on the horizontal member 4 so that the bolts 9 and 9 are fitted into the through holes 10, and the nut 18 is attached to the bolt 9 protruding from the base 11 via the washer 23. By screwing and tightening, the lower pillar 6 and the horizontal member 4 (and other horizontal members 4 ') are joined to each other, and the joining plate 12 projects from the upper surface directly above the lower pillar 6 of the horizontal member 4. Will be in the assembled state.
[0016]
In addition, on the upper and lower surfaces of the horizontal member 4, recessed portions 24 and 24 having the same shape and the same thickness as the metal substrate 11 of the joint hardware 1 </ b> A or the mounting hardware 1 </ b> B are provided, and the hardware substrate 11 is fitted into the recessed portion 24. By assembling, the integrity of the joining hardware 1A, the mounting hardware 1B, and the horizontal member 4 is further maintained, and this is a reinforcing device against external force.
[0017]
In the same manner as the gap material 2B on the lower pillar 6 side, the spacer 2A is combined with the joining plate 12 protruding from the upper surface of the horizontal member 4 so as to penetrate the joining plate 12, and the spacer 2A is transparent. The spacer 2A is placed on the horizontal member 4 via the metal substrate 11 so that the nut 18 is engaged in the hole 19, and the joining plate 12 protruding from the spacer 2A is inserted into the slit 20. When the upper column 5 is placed on the spacer 2 and the drift pin 13 is driven into the through hole 21 through the through hole 14, the upper column 5 is assembled and fixed to the horizontal member 4 and the lower column 6, The joined state of the upper pillars 5 and 6 through the horizontal member 4 can be obtained.
[0018]
【The invention's effect】
Since the present invention is configured as described above, even if the upper column and the lower column are provided with a horizontal member, they are integrally joined to each other by a bolt rod, so that the same movement (vibration) is applied to the external force. ), It is possible to obtain a vertical column joining apparatus that is excellent in physical strength.
