Abstract

(57) [Abstract] [Purpose] To provide a member joining device in a wooden structure that is easy to construct and has high structural reliability. [Structure] In a pair of wood members 1, 1 sandwiching a steel plate 4 for joining having a bolt hole 3, the outer diameter is gradually reduced from the opening surface at one end to the joining surface at the other end, and a bolt is formed on the bottom surface. Fitting a pair of steel cone connectors 5 having holes 7,
A high-strength bolt 8 was inserted and tightened across the bolt hole 7 of each cone connector 5 and the bolt hole 3 of the joining steel plate 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for joining members such as columns and beams in a wooden structure.

[0002]

[Prior art]

 FIG. 4 shows a joining device for joining members in a conventional wooden structure. A bolt d is inserted between a pair of wooden members a, a to be joined and an iron plate c inserted into a slit b of the wooden member. It is tightened.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional joining structure, since a gap is formed between the bolt and the bolt hole of the wooden member a, the relative displacement of the joining portion is large, which causes rattling and the joining strength is insufficient.

[0004]

[Means for Solving the Problems]

 The present invention has been proposed in view of the above problems of the prior art, and an object of the present invention is to provide a member joining device in a wooden structure which is easy to construct and structurally reliable. . In order to achieve the above-mentioned object, a member joining device for a wooden structure according to the present invention has a pair of wooden members sandwiching a joining steel plate having a bolt hole from one end opening surface to the other end joining surface. The outer diameter is gradually reduced in accordance with the above, and a pair of steel cone connectors with bolt holes on the bottom surface are fitted, and high strength is achieved across the bolt holes of each cone connector and the steel plate for joining. It is constructed by inserting and tightening bolts.

[0005]

[Action]

 Since the present invention is configured as described above, the outer diameter of the pair of wooden members sandwiching the joining steel plate having the bolt holes is gradually reduced from the opening surface at one end to the joining surface at the other end. By inserting and tightening the high-strength bolts through the bottom bolt holes of the pair of cone connectors and the bolt holes of the joining steel plate, the both wooden members are securely joined.

Since the outer peripheral surface of the cone connector is formed into a taper surface whose outer diameter gradually decreases from the opening surface at one end to the joint surface at the other end, the cone connector can be used as a wooden member. When it is fitted, the tapered surface of the cone connector is closely attached to the inner surface of the fitting part of the cone connector of the wooden member, and no gap is created.

[0007]

【Example】

 The present invention will be described below with reference to the illustrated embodiments. Reference numeral 1 is a pair of wooden members in which a joining steel plate 4 having a bolt hole 3 is sandwiched in a slit 2. 5 is a cone connector, one end of which is open, and a bolt hole 7 is formed in the bottomed part 6 at the other end. Is formed in.

Then, the joining steel plate 4 is sandwiched between the pair of wooden members 1 and 1, and the cone connectors 5 are fitted into the cylindrical holes 1 a provided in each wooden member 1. Then, the high-strength bolt 8 is inserted through the bolt holes 7, 7 of the bottomed portions 6 of the both cone connectors 5, 5 facing each other and the bolt hole 3 of the joining steel plate 4, and the nut 9 is tightened. Join the wooden members 1, 1.

At this time, since the cone connector 5 is formed into a tapered surface whose outer diameter is gradually reduced from the opening end to the bottomed portion 6 having the bolt hole 7, the outer peripheral tapered surface of the cone connector 5 is The inner wall surface of the cylindrical hole 1a provided in the wooden member 1 will not be pressed or bitten, and rattling will not occur at the joint portion of the wooden members 1,1.

[0010]

[Effect of device]

 According to the present invention, as described above, the outer diameter of the pair of wooden members sandwiching the joining steel plate having the bolt holes gradually decreases from the opening surface at one end to the joining surface at the other end having the bolt holes. Then, install a pair of steel cone connectors with bolt holes on the bottom surface, insert high-strength bolts across the bolt holes of each cone connector and the bolt holes of the joining steel plate, and tighten them Since the members are joined, the cone connector closely fits into the inner peripheral surface of the wooden member, and does not cause relative displacement of the joint with respect to the initial load.

Further, even if the bolt hole 7 on the bottom surface 6 of the cone connector is made sufficiently large by a high-strength bolt diameter, frictional joining between the tapered cone connector and the joining steel plate causes a trouble in the yield strength and displacement of the joining portion. Therefore, the machining of the bolt position and the error of the erection are allowed, and the construction is greatly simplified.
