Description

  The present invention is a hardware used for a corner portion of a seismic opening frame that opposes a horizontal force that is attached to the inside of a frame having an opening of a wooden building.

  The seismic opening frame bears horizontal force (seismic force, wind pressure) exclusively by installing a wood frame with rigid corners (moment resistance) in the wooden frame composed of pin joints. It is the role of making it a safe structure.

  For the method of rigidly connecting the corners of the seismic opening frame, the conventional tension bolts and chemical fiber sheets (aramid fiber, carbon fiber, glass fiber, etc.) and fixing with adhesive, conventional joint hardware and bolting or Driving pins have been used. However, in the conventional method, precut processing of the wooden frame and assembly commercialization at the factory are indispensable conditions, and it is necessary to acquire special technologies such as chemical fiber sheet bonding technology.

  Therefore, we developed rigid joint plate hardware that can be easily processed by bending metal plate bending instead of chemical fiber sheets, simplifying mass production of rigid joint plates, recutting of wooden frames, and enabling on-site assembly. As a result, the total cost can be reduced.

JP2013-91998 (metal fitting for wood joining and method for producing the same) JP-A-9-119170 (seismic frame for openings in wooden buildings) JP-A-2006-46055 (Aseismic frame at the opening of a wooden building)

  The thing of patent document 1 is a hardware used when joining the end surface of a 2nd horizontal member to the side surface of a 1st horizontal member, Comprising: This hardware does not become a rigid joint which can also bear the rotational moment of a junction part. . (Mechanically pinned)

  Patent Document 2 discloses a gate-type and box-type earthquake-resistant frame that is used by being incorporated in a structural frame that resists seismic force (horizontal force). These provide a load-bearing wall effect that resists horizontal forces of earthquakes and wind pressures, as well as bracing and structural plywood, in the part of the structural housing that becomes a non-bearing opening.

  Furthermore, Patent Document 3 discloses a gate-shaped opening frame made of a wooden member, a tension bolt, a chemical fiber sheet, a column base metal, and the like.

  However, using these technologies to produce large openings (large span) and at the same time to produce products that can resist seismic forces, accurate precut processing and assembly technology of conventional dedicated precut factories, high-tech Chemical fiber bonding technology was required. However, in the era when more cost reduction is required in the wooden construction market, rationalization of production, transportation, and on-site assembly of wooden seismic opening frames is required while the use of the inexpensive steel structure market is drawing attention. Therefore, it is possible to assemble corner joints on the spot using advancement of plate processing technology and reinforced wood screws that have been researched, evaluated, and announced at academic societies. It is a device of. In other words, by precutting the seismic opening frame at the same time as the shaft structure material, and carrying it to the site and assembling it, the conventional multiple transportation is omitted, and what was manufactured at a separate precut factory is the shaft Enables rational production of prefabricated construction materials. However, unlike chemical fibers, it is necessary to take measures to prevent condensation by heat bridge.

  Therefore, the present invention aims to provide a seismic opening frame that is cheaper than usual and that can be easily incorporated by a general builder in a timely manner by devising a seismic opening frame and a bent hardware.

  As an example, in the case of the box-type seismic opening frame shown in FIG. 16 and FIG. 17, the conventional L-shaped members are not assembled with dedicated joint hardware, but can be assembled with only the bending press processed plate hardware at the corner portion. Down and labor saving.

Since the present invention has been described above, the following effects can be obtained.
B. By combining a seismic opening frame that bears horizontal loads of earthquakes and winds, pillars and horizontal members that handle vertical loads, it facilitates large openings, large spans, and large spaces. Since the torsion of the entire building can be suppressed, the earthquake resistance is improved.
B) Since the corners of the seismic opening frame can be rigidly joined only by bending the hardware, simultaneous manufacturing, simultaneous transportation, and simultaneous field assembly are possible, resulting in a significant cost reduction.
C. New bending metal fittings with a rigid joint at the corners using the highly reliable bending metal manufacturing technology that has been used as a fitting for the wooden frame construction method, and earthquake resistance that has been evaluated for earthquake resistance. With the opening frame, it can be constructed as a frame system that handles horizontal loads due to on-site assembly, a new function.
D. Folding press-worked plate metal parts can be selected according to their required rigidity depending on their shape, and the bending press-worked plate can also be selected by combining the frame building frame and horizontal frame at the corner of the earthquake-resistant opening frame. Hardware can be selected.
