BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a timber joining apparatus for a wooden building according to the present invention. FIGS. 1 and 2 show a first embodiment in which a base A1 and a pillar B1 are joined, and FIG. FIG. 2 is an enlarged view of a part of FIG.

The base A1 is placed on a foundation concrete Bc via a flange piece 2 provided on a screw cylinder 1A, and the base A
1 is an anchor bolt 3 fixed to the foundation concrete Bc
To the foundation concrete Bc.

The screw cylinder 1A is constituted by providing the flange piece 2 at one end (lower end) of the main cylinder 4, and inserting the main cylinder 4 into a through hole 6 provided in the base A1. 2 as base A
1 is combined with the base A1 so as to be received on the lower surface of the base 1.

Since the flange piece 2 is interposed between the base A1 and the base concrete Bc, a gap 7 is formed between the base A1 and the base concrete Bc. The gap 7 serves as a so-called ventilation port. However, there is no need to provide a separate ventilation port in the wooden building.

The main cylinder 4 of the screw cylinder 1A fitted in the through hole 6
In order to insert the connection bolt 8 into the through hole 6 from above, the head of the connection bolt 8 projects from the base A1 and is disposed at a predetermined height. is there.

Incidentally, the "predetermined height position" refers to the width of the base A1, the mounting hole 9 provided in the column B1, and the receiving hole 10 provided in the column B1 in a direction perpendicular to the mounting hole 9.
Column B, which is determined by the positional relationship of
Since the processing of 1 and the like is performed by so-called pre-cut, it is easy to arrange them at a predetermined “predetermined height position”.

If a mark such as a score line is provided on the connection bolt 8, it is easy to make the amount of protrusion of the connection bolt 8 from the base A1 constant with reference to the mark. It can be performed without any inconvenience.

The column B1 includes the mounting hole 9 provided with an open end face (lower surface), and the receiving hole 10 is formed so as to correspond to the predetermined height position of the head 8a. It is provided so as to be orthogonal to the upper end of the base B1. The round head 8a of the connecting bolt 8 is engaged with the mounting hole 9 of the column B1 and is arranged at the position of the receiving hole 10, and the base A1 is mounted on the base A1. The base A1 and the column B1 are combined with the base A1 so as to be erected and fitted with the fastening tube 11 in the receiving hole 10 formed in the column B1 and combined with the head 8a of the connection bolt 8. Is done.

As shown in FIG. 2, the fastening cylinder 11 has a cavity 11c in the form of a bottomed cylinder having a semicircular cross section in which the head 8a of the connection bolt 8 can be engaged. Part 1
The connection bolt 8 is engaged in the direction 1b (the fitting direction with respect to the receiving hole 10), and the slit 12 having a width smaller than the diameter of the head 8a is formed from the distal end 11a to the base end 11b (the receiving hole 10). To the cavity 1)
1c is provided on the straight wall 11c ', and the straight wall 11c' constitutes a slit-side inner wall for receiving (engaging) the head 8a of the connection bolt 8, and the straight wall 11c '(slit-side inner wall). To
A taper 14 is provided in the direction from the distal end 11a of the screw cylinder to the proximal end 11b so as to gradually separate from the distal end of the connection bolt 8.

The reason why the end portion 11b of the fastening cylinder 11 is made thick and substantially frusto-conical is that the driving strength to the receiving hole 10 is increased and the end portion 11b is securely fixed (fitted) to the column B1.
The thickness of the straight wall 11c 'is made thicker in order to cope with the applied load.

The fastening cylinder 11 is inserted into the receiving hole 10 so that the connection bolt 8 is located on the extension of the slit 12.
Is inserted into the receiving hole 10 by a tool, the connecting bolt 8 (the shaft portion thereof) is engaged with the slit 12, the head 8a is pushed up by the taper 14, and the straight wall 1 is pushed up.
1c ', the column B1 and the base A1 are drawn together (although the column B1 side is drawn to the base A1 because the base A1 is fixed by the anchor bolts 3).

FIG. 3 is a longitudinal sectional view of the second embodiment. In the second embodiment, a horizontal member A2 such as a beam is interposed between a lower column B1 'and an upper column B1''. This shows an example of a device in the case of joining to each other. The head 8'a side of the connection bolt 8 'is engaged with the mounting hole 9' of the upper end opening provided in the lower pillar B 'so as to be orthogonal to the mounting hole 9. Receiving hole 10 'provided in the lower pillar B1'
The fastening cylinder 11 'and the connection bolt 8' are assembled to each other by driving the fastening cylinder 11 'into the lower end B1' and the screw cylinder 1A '(first Unlike the embodiment, the flange piece 2 is omitted), and another connecting bolt 8 ″ is screwed and assembled to the screw cylinder 1A ′, and these are connected to the horizontal member A2. Through hole 6 'formed in
So that the horizontal member A2 is passed through the lower column B1 '.
The mounting hole 9 'is placed on the same as the column B1 of the first embodiment.
And a head 8 ″ a of a connection bolt 8 ″ protruding from the horizontal member A 2 is engaged with an assembling hole 9 ″ of the upper pillar B 1 ″ having the receiving hole 10 ″. 8 ″ a and fastening cylinder 11 ′
'In the same manner as in the first embodiment, and upper and lower columns B1', B1 '
'And the horizontal member A2 are joined together.

As schematically described, the assembling holes 9 ', 9 ", the receiving holes 10', 10", the connecting bolts 8 ', 8 "and the fastening cylinder 11', referred to in the second embodiment. 11 ″ is the same as that of the first embodiment (illustrated symbols such as tapers are omitted), and the base A1 of the first embodiment is replaced by the horizontal member A2 of the second embodiment, The connecting bolt 8 is attached to the lower pillar B1 'in a state where the connecting bolt 8' attached to the fastening cylinder 11 'is assembled.
Is the connecting bolt 8 ″, and the fastening cylinder 11 is the fastening cylinder 11 ″.
The assembling hole 9 corresponds to the assembling hole 9 ", and the receiving hole 10 corresponds to the receiving hole 10". The assembling relationship is the same as in the first embodiment, and the description is omitted.

The third embodiment shown in FIG.
'Shows an example of an apparatus in the case of joining the second horizontal member A2''and the second horizontal member A2''.
2 and 3 show the same apparatus example (although there is a difference in length and width) where B3 is directly joined, the first horizontal member A2 'is used as the lower pillar B1' of the second embodiment, and the second horizontal member A2 '' is used. Upper pillar B1 'of the second embodiment
Since the configuration of the third embodiment can be understood by corresponding to, the description is omitted.

The screw cylinders 1A 'and the like are denoted by the same reference numerals as in the second embodiment.

[0019]

Since the present invention has the above-described structure, it is possible to join a pair of woods, and it is also possible to join without using a screw cylinder, a connecting bolt and the like used for joining without protruding to the peripheral surface of the wood. Therefore, the work of attaching the wall material fixed to the wood can be easily performed.

Further, since the two pieces of wood can be attracted to each other and joined by utilizing the taper, the joining state can be strengthened.
