Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a connecting structure used for connecting building members such as beams and columns in a wooden house to each other.

[Conventional technology]

As shown in FIG. 4, when the beam 2 is connected to the pillar 1 in the related art, the beam 2 is connected to the pillar 1 by means of ten mortises 3 and then the connecting bolts 4 are penetrated from the pillar 1 side in the beam 2 direction. The tip portion is projected from the side wall surface of the nut hole 21 provided in the beam 2, and the fixing nut 5 is fixed to this protruding portion (of the connecting bolt 4) by screwing it through the washer 6.

[Problems to be solved by the device]

By the way, since the conventional washer is a flat washer, when the pillar (made of wood) 1 and the beam (made of wood) 2 are dried and shrunk over time, the fixing nut 5 is loosened, so that the wood and the beam are It has a defect that the connection structure is deteriorated and the rotation of the connection bolt 4 is promoted, and an unpleasant metallic sound is generated.

In this case, if a spring washer is used instead of the flat washer, the above-mentioned drawbacks are solved, but in the conventional spring washer, the spring is welded to the back surface of the washer, so the shape becomes complicated. , This results in a narrow nut hole 2
There is a disadvantage that the screw fitting work inside is troublesome.

The problem of this invention is to eliminate such inconvenience.

[Means for Solving the Problems]

In order to achieve the above object, the construction member connection structure according to the present invention comprises one construction member and another construction member, wherein a nut hole is formed in the one construction member, and a side wall surface of the nut hole is formed. Forming a bolt hole in the other building member together with forming a bolt hole, contact the one building member and the other building member in a state in which each bolt hole is substantially the same axis, By inserting a connecting bolt from the outer opening end of the bolt hole in the other building member into the bolt hole and the bolt hole of the one building member, the tip of the connecting bolt is projected into the nut hole, and the connecting bolt is formed. In the connecting structure of the building member for connecting the one building member and the other building member by screwing a fixing nut through a washer to the protruding portion of the, the cross-sectional shape of the nut hole is circular. Substantially curved at a constant curvature in the axial direction of the nut bore a vertical direction axis with forming the washer with an elastic material,
This curvature is smaller than the curvature of the side wall surface of the nut hole.

The washer may be rotatably connected to the fixed nut.

[Action]

Since the structure connecting structure according to the present invention is configured as described above, since both end edges (in the curving direction) of the washer make line contact with the side wall surface of the nut hole, the inner portion of the washer and the nut hole are connected. Clearance is formed between the side wall surface of
The so-called washer becomes a double-supported beam, and as a result, the washer functions as a spring washer in combination with the elasticity of the washer.

Here, since the washer is not a separately welded spring, the shape is not complicated, resulting in easy handling,
The screw fitting work in the nut hole can be done easily.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a pillar, and 2 is a beam which is connected to the pillar 1 by ten. The pillar 1 and the beam 2 correspond to the "building member" of the present invention. Reference numeral 21 denotes a nut hole, which is formed on the upper surface of the beam 2. The nut hole 21 has its axis arranged substantially vertically, and its cross section is a perfect circle. For this reason, the side wall surface of the nut hole 21 forms a curved surface with a constant curvature. 11 is a bolt hole formed in the pillar 1,
It penetrates the side surface of the pillar 1. Reference numeral 22 denotes a bolt hole formed in the beam 2, which is arranged in the longitudinal direction of the beam 2 and opens on the side wall surface of the nut hole 21. The bolt holes 11 and 22 have substantially the same axis. Reference numeral 4 denotes a connecting bolt, which is inserted into the series of bolt holes 11 and 22 from the side of the column 1 and has its tip portion projected into the nut hole 21. The connecting bolt 4 reinforces the connecting structure between the pillar 1 and the beam 2. Reference numeral 5 denotes a fixed nut, which is arranged in the nut hole 21 and is screwed to the tip of the connecting bolt 4 via a washer 6. The washer 6 and the fixed nut 5 are integrally connected as described later.
And by tightening this fixing nut 5,
The connection bolt 4 can be fixed. The washer 6 is curved with a substantially constant curvature in the axial direction of the nut hole 21 about the vertical direction. Since the washer 6 is made of a metal material (elastic material) and its curvature is smaller than that of the nut hole 21, as shown in FIG.
Acts as a spring washer when installed in 1.

Next, the fixing nut 5 and the washer 6 will be described in detail with reference to FIG.

In the figure, reference numeral 61 denotes a bolt through hole of the washer 6, and the connecting bolt 4 penetrates the washer 6 through the bolt through hole 61 formed in the central portion of the washer 6. Reference numeral 51 is a connecting tube, which is integrally formed on the peripheral edge of the lower end of the fixed nut 5 with the same axis. The connecting cylinder 51 penetrates through the bolt through hole 61 of the washer 6 and is caulked 511 at the tip edge thereof so as to be rotatably connected to the washer 6. A female screw portion 52 of the fixed nut 5 is extended on the inner wall surface of the connecting cylinder 51.

In addition, in this embodiment, the fixed nut 5 and the washer 6 are connected, but these 5 and 6 may be separate bodies.

[Effect of device]

The construction member connection structure according to the present invention comprises one construction member and another construction member, a nut hole is formed in the one construction member, and a bolt hole is formed in a side wall surface of the nut hole. Bolt holes are also formed in other building members, and the one building member and the other building member are brought into contact with each other with their bolt holes having substantially the same axis center, and bolt holes in the other building member. The connecting bolt is penetrated from the outer open end of the bolt hole to the bolt hole of the one building member to project the tip of the building bolt into the nut hole, and the projecting portion of the connecting bolt via a washer. In a connection structure of a building member that connects the one building member and the other building member by screwing a fixing nut, a cross-sectional shape of the nut hole is circular, and the washer is made of an elastic material. Substantially curved at a constant curvature in the axial direction of the nut bore a vertical direction axis,
Since this curvature is made smaller than the curvature of the side wall surface of the nut hole, both end edges (in the bending direction) of the washer make line contact with the side wall surface of the nut hole, and as a result, the inner side of the washer and the side wall surface of the nut hole are A clearance is formed between them, the so-called washer is in the state of a doubly supported beam, and therefore, in combination with the elasticity of the washer,
The washer functions as a spring washer.

Here, since the washer is not separately welded with a spring, the shape is not complicated, so that the washer is easy to handle and the screw fitting operation in the nut hole can be facilitated.

Therefore, when the construction member connection structure according to the present invention is used, loosening in the construction member connection structure can be prevented by a simple operation.

If the washer is rotatably connected to the fixed nut, it becomes easier to install the washer in the nut.
