Description

  The present invention relates to a seismic reinforcement apparatus for buildings such as 1 to 3 floor wooden structures.

The seismic method to prevent the building from collapsing during earthquakes is as follows: 1. Seismic isolation method that attenuates earthquake vibration transmitted from the ground and transmits it to the building. 2. Building structure stress generated by the seismic force transmitted from the ground is structural material. There is a stress degree design method 3 designed so as not to reach the fracture stress of 3 and a method of preventing collapse by directly controlling the horizontal deformation of the entire building during an earthquake.
In the third technique, there are the following techniques for seismic reinforcement using a string-like member.
Japanese Patent Application Laid-Open No. 2004-239038 removes the beam position for seismic reinforcement of an existing residence and tightens the outside of the column horizontally with a strip-shaped steel plate or the like, but there are cases where the seismic strength is weakened. In addition, the plan to reinforce the truss type with the steel plate, the intermediate column with the strip steel plate, the reinforcement between the middle columns with the strip steel plate, and the upper part of the opening with the strip steel plate is considered to be effective. Removal and establishment are necessary.
Next, Japanese Patent Laid-Open No. 2007-154479 discloses that a string-like member is fixed to a base near a protruding corner column via a turnbuckle, and passes through an intermediate beam and is bound to one of horizontal bracings at the upper part of the uppermost beam. The other end of the member is bundled at the upper part of the uppermost beam and the string-like member fixed to the base near the protruding corner column facing each other via a turnbuckle. Similarly, string members are also used for the other two projecting corner columns, and the building structure is pressed in the vertical direction by binding and reinforcing it with the other one of the horizontal braces at the top of the uppermost beam. It is also unclear whether there is no measure against horizontal displacement of the cable, and the method of fixing the string-like member to the base matches the seismic force.
Japanese Patent Laid-Open No. 2010-37782 is a method of controlling horizontal displacement at the time of an earthquake as a seismic reinforcement method for an existing house. Although it is supposed to control the deformation, this method causes uneven distribution of rigidity, and it cannot prevent the influence of huge tension and vibration acting on the opposite outer wall of the existing house facing the high-rigidity building and the two-story floor beams on both sides. It may decrease the earthquake resistance. Depending on the input direction of the seismic force, a highly rigid building may become an obstacle to the building.

As shown in FIG. 15, the fixing member 9, the fixing member 24, the fixing member 27, and the fixing member 17 installed at the four corners of the foundation concrete of the two-story wooden building 1 are each fixed to two string-like members. It has a ring 95 and fixes two string members. The connecting member 10, the connecting member 12, the connecting member 14, and the connecting member 16 installed at the four projecting corners of the two-story floor beam height of the two-story wooden building 1 are two cylindrical shapes that bend horizontally. Each of the parts 106 has two cylindrical parts 107 that are bent horizontally and vertically, and the directions of the string-like member 20, the string-like member 21, the string-like member 22, and the string-like member 23 are changed. Next, the support member 11, the support member 13, the support member 15, and the support member 28 have four cylindrical portions in the vertical direction, and each house three string members. This is because the string-like member that controls the horizontal deformation of the facing outer wall of the support member installation outer wall is changed to the vertical lower portion by the connecting members at both ends of the support member installation outer wall and fixed to the fixing member. This is because the storage portion for the string-like member is empty.

Order to construction of the present invention, when the two-story floor space such as shown in FIG. 1 as an example a wooden building 1 of about 120 m ^2, the external corner portion exterior wall finishing material at four positions from the foundation concrete crest 2 Remove about 80cm above the floor beam and about 10cm from the projected corner to both outer walls to expose the projected corner pillars, and place the second floor floor beam every 2-3m depending on the length of each outer wall surface. Since the outer wall finishing material is removed by removing the outer wall finishing material and the second-floor floor beam is exposed, a factory-made steel member is attached, and a pretension is introduced through the string-like member. The outer wall removal range is much smaller than the seismic retrofitting work , basically no internal work is required, and it is a low-cost construction that can reduce inconvenience during the construction of residents by short-term construction, and only protects buildings from collapse during earthquakes Not only can the building structure be protected from damage .

  If the foundation concrete is insufficient in strength or if it is difficult to fix the fixing member, install an appropriate ground anchor such as a pile on the nearby ground to make the fixed end of the string-like member.

  When there is a corner in the outer wall of the target building, the number of connecting members installed at the corner of the outer wall of the building increases and the shape changes slightly. The brace of the support member outside the entrance corner is a three-dimensional truss type, entasis type, spoke type, or a composite type thereof.
