Description

  The present invention relates to a joining structure for joining two construction members constituting a building, such as a column and a beam, and a joining device used for joining, and in particular, the invention relates to two constructions to be joined. The present invention relates to a joining structure in the case where at least one of the members is made of wood, and a joining device used for the joining.

  Conventionally, a wooden ramen construction method is used to join columns and beams in a wooden building. This wooden ramen construction method has been developed for large-scale wooden structures such as factories, school buildings, apartment houses, and government buildings because it can realize large openings and large spaces and has a high degree of freedom in layout. In recent years, in view of the characteristics of the wooden ramen construction method described above, the wooden ramen construction method has been incorporated into ordinary houses in order to fulfill the demand for the first floor to be built-in garage.

  In this wooden ramen construction method, for example, the joint between the column and the beam is firmly fixed so that the column and the beam alone can withstand a horizontal load caused by an earthquake or wind, without depending on a wall or a brace. In this case, since a considerable load is applied to the joint between the column and the beam, the design of the joint is important. So far, joining using adhesives, joining using hardware such as drift pins and bolts, etc. Various proposals have been made (see, for example, Patent Document 1).

JP 2009-179947 A

  Bonding with adhesive increases the strength and rigidity of the joint, so it can withstand small earthquakes with high frequency of occurrence, but it has low toughness (stickiness), so it can bond with large earthquakes with low frequency of occurrence. The deformation of the part is not allowed and the energy of the earthquake cannot be absorbed. On the other hand, joining with hardware increases the toughness (toughness) of the joint due to the stickiness of the hardware, so it has the effect of absorbing the energy of large earthquakes, but the rigidity of the joint is low. There is a problem that it tends to be stable. In addition, in any joint, there is a possibility that destruction by wood penetration or splitting occurs due to the occurrence of a large earthquake, and there is a problem in that the performance of the joint is significantly reduced after the earthquake occurs.

  This invention has been made to solve the above-mentioned problems, and exhibits high rigidity at the time of normal earthquakes and occurrence of small earthquakes with high occurrence frequency, and at the time of occurrence of large earthquakes with low occurrence frequency. It aims at providing the joining structure of the construction member which exhibits sufficient toughness (toughness) and energy absorption performance, and a joining device.

  In the construction structure for joining members according to the present invention, at least one of the two construction members to be joined is made of wood, and a metal joining member is integrally attached to the construction member made of wood. A metal accessory plate integrally attached to the construction member to be joined is superimposed on the pressure contact surface of the joining member, and the bolts passed through the bolt insertion holes provided in the accessory plate and the joining member are attached to the joining member. When a force exceeding the frictional force between the pressure contact surface and the accessory plate is applied, the pressure contact surface of the joining member and the accessory plate are tightened so as to slip, and the accessory plate is in pressure contact with the joining member.

  In the above-described joint structure of construction members, the joint member and the accessory plate are in a rigid joint state with respect to a small earthquake with high occurrence frequency, and can withstand the load caused by the earthquake. For large earthquakes with a low frequency of occurrence, slip occurs between the joint member and the accessory plate, allowing deformation of the joint and absorbing the earthquake energy.

  In a preferred embodiment of the present invention, both of the two construction members to be joined are made of wood and joined with the side surfaces of one construction member facing the end face of the other construction member. However, the present invention is not limited to this, and can also be applied to joining in a state in which the end surface of one construction member is opposed to the end surface of the other construction member or a state other than 90 degrees.

  In the above-described configuration of the present invention, the joining member may be in various forms, one of which comprises a metal pipe having a bolt insertion hole through which the bolt is passed. The both end surfaces of the pipe are integrated in a through hole formed in the construction member, and a pair of accessory plates parallel to each other are overlapped on each pressure contact surface. It is in pressure contact.

  Another aspect of the joining member is a metal pipe having a bolt insertion hole through which the bolt is passed, and an attachment plate provided on an end surface of the construction member of the wood. The inner end face is fitted into and integrated with the front and rear through-holes formed across the insertion groove so that the inner end face protrudes into the accessory plate insertion groove. The front and back surfaces of the accessory plate inserted into the accessory plate insertion groove are overlapped and pressed.

  Further, another aspect of the joining member is a T-shaped metal plate in which a joining plate having bolt insertion holes is integrally formed on the substrate, and the substrate is applied to the end surface of the construction member made of wood. The front and back surfaces of the joining plate are used as pressure contact surfaces, and the accessory plates are overlapped and pressed on the pressure contact surfaces.

  Each said joining member is integrally attached to the construction member of a timber, for example by the method of adhesion | attachment, screwing, press fit, and crimping | compression-bonding.

  In a preferred embodiment of the present invention, the bolt insertion hole formed in each accessory plate is set to a shape and a size that allow slippage between the joining member and each accessory plate.

  A construction member joining apparatus according to the present invention is for joining two construction members, at least one of which is made of wood, and is a metal joining member that is integrally attached to the wood construction member, A metal accessory plate that is integrally attached to the construction member of the joining partner and is superimposed on the pressure contact surface of the joint member, and the pressure contact surface and accessory plate of the joint member that are passed through the bolt insertion holes provided in the accessory plate and the joint member And a bolt that is tightened so as to cause a slip between the pressure contact surface of the joining member and the accessory plate when a force exceeding the frictional force between them is applied, and presses the accessory plate against the joining member. .

  According to the construction member joining apparatus described above, a small earthquake with a high occurrence frequency is in a rigid joint state between the joining member and the accessory plate, and can withstand the load caused by the earthquake. For large earthquakes with a low frequency of occurrence, the joint member slips between the joining plate and the construction member is allowed to deform, and the energy of the earthquake can be absorbed.

  According to the present invention, high rigidity is exhibited for small earthquakes with high occurrence frequency, and sufficient toughness (stickiness) and energy absorption performance are exhibited for large earthquakes with low occurrence frequency. It is excellent in earthquake resistance, and there is no risk of destruction due to the penetration or splitting of wood due to the occurrence of an earthquake, and it is possible to prevent the performance of the joint from deteriorating after the occurrence of an earthquake.
