Description

  The present invention relates to an interlayer adhesion hardware for a wooden multilayer building.

  The wooden frame wall construction method is a kind of construction method of a wooden structure of an architectural structure, and is generally known as a two-by-four construction method. This construction method integrates the load-bearing wall and the rigid floor by assembling standardized wood in a frame shape and supporting it with a wall or floor on which structural plywood is struck. Buildings based on the two-by-four method are excellent in earthquake resistance, fire resistance, heat insulation, confidentiality, soundproofing, etc., and can be completed at a lower cost and in a shorter period of time than reinforced concrete structures (RC structures) and steel structures (S structures) However, it is advantageous and is widely used.

Buildings other than fireproof buildings are restricted in areas designated as fireproof areas in city planning. Fireproof building is a part where the main structural part is fireproof structure or has been confirmed by the fireproof performance verification method etc. that it can withstand until the end of the fire, and there is a possibility of fire spread at the opening of the outer wall Refers to buildings with fire doors. The building of two-by-four construction method, not conventional refractory structure was observed, but was unable to building only in 100m ² following a small wooden building, recognized as a major structural part is fireproof structure in the two-by-four construction method in 2004 It was done. As a result, two-by-four refractory buildings up to four stories can be designed in the same way as refractory buildings such as reinforced concrete, regardless of the type and area of the building. In the future, it is expected that there will be a lot of entry into the 4-story middle-rise building market by the two-by-four method in private houses, apartment houses, stores, shopping malls, hotels, hospitals, nursing care facilities, etc.

  In a wooden building, in order to prevent the building from being lifted up, a hall down hardware for connecting the upper and lower pillars to each other and the foundation, foundation, and pillars is installed at the corner of the building on each floor. However, in two-by-four buildings consisting of each level, the lifting force due to earthquakes and the like increases, and it is difficult to deal with ordinary hole-down hardware.

Therefore, instead of the hole-down hardware, a method of tightening with a long tie rod between the top level of each level of the wooden building and the lower floor level can be considered. As shown in FIG. 1, the long tie rod 20 is preferably provided with a washer 10 and a nut 31 that support the tie rod 20 in each layer. At that time, it is necessary to eliminate a gap generated between the washer 10 and the wood 71 due to contraction of the wood of each layer after construction.

For this reason, screw tightening devices that tighten bolts and nuts with a constant tightening torque have been developed. For example, Patent Document 1 (see FIG. 3) includes a spring spring 1 having winding elasticity and locking means 2 that locks the spring 1 in a state having winding elasticity. , Engaged with a member to be tightened H such as a bolt or nut, the rear end side of the outer diameter of the mainspring is fixed to a material S to which the member to be tightened H is mounted, and the locking means 2 can be locked. Disclosed is a screw fastener characterized in that it comprises the following: In Patent Document 2 (see FIG. 4), a washer 10 having a hole 12 through which a tie rod extending vertically over a multi-layer floor of a wooden building passes, a nut placed on the washer 10 and screwed into the tie rod. 31, a rotating body 30 that has a side wall 32 that is erected so as to surround the tie rod and that is integrated with a nut 31; The plate spring 35 is fixed to the upper portion of the side wall 32 of the rotating body and applies a force for rotating the nut 31 downward, and the leaf spring 35 comes into contact with the outer side of the rotating body 30 so as to be detachable. There is disclosed a plate spring fixing means 50 for fixing, in which a lower portion of the side wall 32 and the nut 31 are integrated by a detachable coupling means 38.

However, the conventional screw tightening device described above is satisfactory in terms of tightening nuts where there is a long tie rod extending in the vertical direction, ease of installation of the device, ease of processing, functionality, etc. It wasn't possible.

  Thus, the gist of the present invention is that the bottom portion has a hole through which a long tie rod extending vertically over the multilayer floor of the wooden building is inserted, and is attached between the nut and the washer. In a cup-shaped container having an open top, a coil spring having a coil spring having a cross-sectional diameter of 3 mm to 5 mm, a coil diameter of 30 mm to 40 mm, and an effective winding number of 8.0 to 10.0 is connected at one end to the cup-shaped container. This is an interlayer adhesion hardware for a wooden multi-layered building which is fixedly accommodated and accommodated on the back surface of a nut receiving plate having a hole through which a long tie rod is inserted, which is fixed to the inner bottom portion of the tie rod.

  The present invention is configured as described above, and has a cross-section of a coil spring in a cup-shaped container having a hole at the bottom through which a long tie rod extending vertically over a multi-layered floor of a wooden building is inserted. A coil spring having a diameter of 3 mm to 5 mm, a coil diameter of 30 mm to 40 mm, and an effective number of windings of 8.0 to 10.0 is fixed at one end to the inner bottom of the cup-shaped container, and the other end is arranged at the top. Since it is fixed and accommodated on the back surface of the nut receiving plate having a hole through which the long tie rod is inserted, the wood is thinned by drying due to secular change, or the wood is deformed by shaking such as an earthquake. Even if a gap occurs between the back surface of the washer and the wood, the bottom back surface of the cup-shaped container always presses the washer due to the expanding pressure of the coil spring having a strong spring force. With wood In which it is possible to prevent the occurrence of gaps. In particular, the coil spring is formed by fixing one end of the coil spring to the inner bottom of the cup-shaped container and the other end fixed to the back surface of a nut receiving plate disposed on the top thereof. If this happens, this will not shift, and even if the axial center shifts, there is no possibility that the coil spring will jump out of the cup-shaped container.
