Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a connection structure used when connecting columns and beams or beams to each other in a wooden building [Prior art] Fig. 1 shows such a connection. The first conventional example of the structure is shown in Fig. 2.
This shows a conventional example.

A first conventional example is one in which a beam 1a and a beam 1b are connected by a joint with a seat.
The two beams are connected by fitting a protruding piece 5 protruding from the other beam 1b.

However, in this connection structure, since the beam 1b is supported by the projecting piece 5 provided protruding from the beam 1b, the connection strength thereof is weak.

Further, in the second conventional example, the beam 7 and the column 9 are connected by a seat slot, and the connection is reinforced by a ladder board pole 1-11.

However, in this connection structure, since the ladder plate bolts 11 are exposed to the outside, there is a disadvantage that the decoration is inferior.

[Purpose of the invention]

This invention was made based on the above-mentioned situation, and its purpose is to provide a connecting structure for wooden buildings that is extremely superior in connecting strength and decorativeness.

The purpose of this is to provide a hook and stopper on the supported member made of water, and also to provide a catch and stopper on the support member made of wood, and to lock the hook and stopper to the receiver of the support member. In the connection structure for connecting the supported member to the supporting member, the hooking stopper has a locking piece erected downward on the base, and the base is in a state where the locking piece is exposed. and the receiver is embedded in the supported member, and the stopper is embedded in the support member with the base having the locked piece facing upward and the locked piece facing upward. This was achieved by locking the locking piece of the supported member to the locking piece of the support structure.

[Explanation of Examples]

Hereinafter, embodiments of the connection structure according to the present invention will be described based on FIGS. 3 to 5.

First, in FIG. 3, reference numeral 13 denotes a hook, which has a disk-shaped base 15. 17 is a locking piece, and the base 15
It is erected on the surface, with its tip facing downward.

This locking piece 17 is a locking piece 2 of a receiving stopper 21 which will be described later.
9 fJ), and in order to make the lock firm, a taper 17a is formed on the back surface of the tip. .

In addition, 19.19. ... is a screw hole into which a fixed egg is inserted.

Next, in FIG. 4, reference numeral 21 denotes a receiving tool, and the hook has a disk-shaped base 23 like the stopper 13. 25 is a picture-shaped locked part +A having an opening 27 at the top, and is integrally cast on the surface of the base 23. 5. This locked gli material 2
The tip wall portion located at 5 acts as the locked piece 29 according to the present invention, and like the locking piece 17 of the stopper 13, the above-mentioned hook is provided on the back side in order to make the stop solid. A taper 29a is formed (see FIG. 5). In addition, 33,
33. ... is a screw hole into which a fixing screw is inserted.

FIG.
This shows the connected structure using .

35 is a beam, which corresponds to a supported member in the present invention. Reference numeral 37 is a round hole, which is bored in the tip &iii surface of the beam 35. The base I5 of the hook 13 is buried in this round hole 37, and the fixing screws 39, 39 . It is screwed on by... Note that when the base plate 15 is buried in the round hole 37, the locking piece 17 thereof faces downward.

On the other hand, 41 is a pillar, which corresponds to a support member in this invention. Further, 43 is a round hole having the same diameter as the round hole 37 of the beam 35 described above, and is bored in the side surface of the column 41.

The receiving stop 21 is embedded in this round hole 43 with the locked piece 29 facing outward, and the fixing screw 40, 40.・・・
・It is screwed on by. In addition, at this time, the locked piece 2
9 is facing upward.

In order to hook the beam 35 to which the stopper 13 is screwed, and to hang the beam 35 to the pillar 41 to which the stopper 21 is screwed, it is necessary to attach the beam to the support 21 of the pillar 41 that has already been installed. 35 can be achieved by bringing the stopper 13 close to the stopper 13, and by engaging the locking piece 17 of the stopper 13 onto the locked piece 29 of the receiving member 21 from above. At this time, since the tapers 17a and 29a of the locking piece 17 and the locked piece 29 come into close contact with each other, the connected state becomes firm. In order to improve the fit between the beam 35 and the pillar 41, a slight gap is formed between the base 23 of the stopper 21 and the locking piece 17 of the stopper 13.

Tables 1 to 3 show the connection structure according to the present invention (external f180
Fig. 3 shows the results of strength tests regarding the first conventional example and the second conventional example (using a latching tool and a receiving tool of mm).

The test method is to attach columns (100 mm long, 100 mm wide, and 100 mm wide) at both ends of a beam (100 mm long, 200 mm wide, and 100
mm ) are connected and a load is applied to the center of the beam.

Table 1 (present invention) Table 2 (first conventional example) Table 3 (second conventional example) In Tables 1 to 3, when the connection structure of the present invention 1 is compared with the slave side, the connection structure of the present invention The city weighs 4,480 kg.
However, in the first conventional example (Table 2), the head creaks when the load is 960 kg, and in the second conventional example (Table 3), when the load is 3200 kg. From this, it can be seen that the connection structure of the present invention is more than five times that of the first conventional example, and the second
It is clear that the strength is 1.4 times or more that of the conventional example.

〔Effect of the invention〕

In the connection structure in a wooden building according to the present invention, a hooking stopper is provided on the supported part H made of water, a receiving tool is provided on the supporting member made of wood, and the hanging stopper is attached to the receiving part LJ of the supporting member. In the connection structure in which the supported member is connected to the support member by being locked to a stopper, the hook stopper has a locking piece erected downwardly on a base, and the base is connected to the support member. is embedded in the supported member with the locking piece exposed; is buried in the support member, and the locking piece of the supported member is locked to the locking piece of the support member, so that the hook is exposed on the surface of the stopper and the receiver. Therefore, the decorativeness of the connection structure is improved.

Furthermore, as is clear from the above test results, the connection strength is significantly superior to that of the conventional example.

Furthermore, since the hook can be connected by simply dropping the stopper from above toward the stopper of the receiver, the connection work is extremely simple.

In addition, when installing a stopper for a hook or a stopper for a receiver on a supported member or supporting member, the amount of cutting is small, and the cross-sectional area of chipping is small, so the strength of the supported member or supporting member is reduced. You won't be hit.

In addition, if the base 13 of the hook and the base of the receiving stop are formed in a disk shape, processing at the time of attaching the supporting member and the supported member is easy, and the strength is also improved.

In addition, if the catch is formed in the shape of a picture on the piece to be locked in the stopper,
The supporting strength of such a locked piece is improved.

Furthermore, if a taper is formed on each contact surface where the locking piece of the latching tool and the locked piece of the receiver stopper come into contact with each other, the locking piece and the locked piece will come into close contact with each other without any gaps. , the connection strength is in the opposite direction.

Furthermore, if the hook and the catch are integrally formed by casting, their manufacture becomes extremely easy.
