Description

  The present invention relates to a turnbuckle. More specifically, the present invention relates to a turnbuckle having a damping function.

  In response to the lessons learned from the collapse of many wooden houses in the Great Hanshin Earthquake, efforts have been made to improve the earthquake resistance of wooden houses.

  As a means for improving the seismic resistance, the joint is made to have an impact absorbing ability. For example, as shown in FIG. 5, a joint damper 60 is provided in the joint 50. In the figure, reference numeral 70 indicates the foundation, and reference numeral 80 indicates the foundation.

  FIG. 6 shows an example of the joint damper 60. As shown in FIG. 6, the joint damper 60 includes a column side steel plate 61 attached to the column 51, a beam side steel plate 62 attached to the beam 52, and a viscoelastic body 63 in close contact therebetween. The

  By providing the joint damper 60 in the joint 50, the shaking of the house due to an earthquake or the like is absorbed by the viscoelastic body, and the house is prevented from collapsing.

  However, when the joint damper 60 is provided, its installation work is required, and since it is an extra work that does not exist in the conventional work, the construction becomes complicated and the construction is prolonged. There's a problem. This problem of prolonged construction is a major problem when retrofitting existing houses that require rapid construction.

  The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a turnbuckle that improves the earthquake resistance of a house, particularly a wooden house, according to a conventional construction procedure.

The turnbuckle of the present invention is a turnbuckle comprising a main body, a damping member, and a nut, the main body having through holes through which rod-shaped braces are inserted at both ends, and the damping member is a rectangular tube body The length of the side of the damping member facing the side opening of the main body is such that the damping member is inserted from the side opening. In addition, the surface facing the inner surface of the side opening is in contact with the inner surface so as not to rotate.

  Thus, the turnbuckle of the present invention is used for seismic reinforcement of a house.

  According to the present invention, there is an excellent effect that the earthquake resistance of the house can be improved by the same construction procedure as that of the conventional turnbuckle reinforcement.

  Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.

Embodiment 1
FIG. 1 is a schematic view showing a wooden house framework to which a turnbuckle according to Embodiment 1 of the present invention is applied. As shown in FIG. 1, this wooden house has a rod-shaped brace 1 stretched by a turnbuckle 10 to prevent rolling.

  2 and 3 show the details of the turnbuckle 10. In FIG. 1, reference numeral 2 indicates a pillar, reference numeral 3 indicates a beam, reference numeral 4 indicates a foundation, and reference numeral 5 indicates a base.

  As shown in FIGS. 2 and 3, the turnbuckle 10 includes a main body 12, a damping member 14, and a nut 16 as main components.

  The main body 12 is basically the same as that used for a normal turnbuckle, but the through hole 12a through which the rod-shaped brace 1 is inserted is a male screw 1a formed at the end of the brace 1. There is a difference in that a female screw is not formed and is simply perforated. The width w of the space 12b of the main body 12 is adjusted so that the nut 16 can be inserted from the side, but the nut 16 does not rotate.

  The damping member 14 is a cylindrical body having a truncated cone shape at the front end portion made of, for example, a low resilience sponge or vibration proof rubber, and a through hole 14a through which the rod-shaped brace 1 is inserted is directed from the front end toward the rear end. It is formed through. Further, the shape of the attenuation member 14 is adapted to be along the inner surface of the end portion of the main body 12.

  The nut 16 is, for example, a hexagonal nut adapted to be screwed into a male screw 1a formed at the end of the brace 1.

  Next, an example of the earthquake-proof reinforcement of the house by the turnbuckle 10 having such a configuration will be described.

  Procedure 1: One end of the main body 12 is inserted through the base end portion where the male screw 1a of one brace 1A is formed, and the other end portion is inserted through the base end portion where the male screw 1a of the other brace 1B is formed.

  Procedure 2: After the damping member 14 is inserted into the base ends of the braces 1A and 1B, the nut 16 is temporarily fixed.

  Step 3: The front end of one brace 1A is attached to a joint part, for example, an upper joint part in a conventional manner, and the front end of the other brace 1B is always attached to a joint part located diagonally, for example, a joint part below the diagonal. Install by law.

  Procedure 4: The turnbuckle 10, specifically the main body 12, is rotated to stretch the braces 1A and 1B.

  Thereby, when a house shakes at the time of an earthquake, since the vibration by the shake is absorbed by the damping member 12, the earthquake resistance of the house is improved. In addition, since the intensity | strength of the brace 1 is determined by the breaking force of the axial part of the brace 1 similarly to the past, the intensity | strength fall by giving a damping function will not be caused.

  As described above, according to the turnbuckle 10 of the first embodiment, the earthquake-proof reinforcement of the house can be achieved by a procedure substantially similar to the reinforcement procedure for the shaking of the house due to the conventional turnbuckle without causing a decrease in strength. Therefore, it is suitable for seismic reinforcement of existing wooden houses that require rapid construction.

Embodiment 2
FIG. 4 shows a turnbuckle 20 according to Embodiment 2 of the present invention. The turnbuckle 20 is obtained by modifying the turnbuckle 10 of the first embodiment, and includes a nut 24 screwed into the base end portion of the brace 1 and a damping member 26 disposed in close contact with the outer periphery thereof. And as a main component.

The damping member 26 is, for example, a rectangular tube made of a viscoelastic body, and the length of the side thereof is adjusted so that the damping member 26 can be inserted into the main body 22 from the side but does not rotate . Next, an example of the earthquake-proof reinforcement of the house by the turnbuckle 20 having such a configuration will be described.

  Procedure 1: One end of the main body 22 is inserted through the base end portion where the male screw 1a of one brace 1A is formed, and the other end portion is inserted through the base end portion where the male screw of the other brace 1B is formed.

  Procedure 2: Temporarily fasten the nut 24 having the damping member 26 disposed on the outer periphery to the base ends of the braces 1A and 1B.

  Step 3: The front end of one brace 1A is attached to a joint part, for example, an upper joint part in a conventional manner, and the front end of the other brace 1B is always attached to a joint part located diagonally, for example, a joint part below the diagonal. Install by law.

  Procedure 4: The turnbuckle 20, specifically, the main body 22 is rotated to stretch the braces 1A and 1B.

  Thereby, when a house shakes at the time of an earthquake, a shear resistance is generated between the nut 24 and the damping member 26 due to the vibration caused by the shake and the vibration is absorbed, so that the earthquake resistance of the house is improved. In addition, since the intensity | strength of the brace 1 is determined by the breaking force of the axial part of the brace 1 similarly to the past, the intensity | strength fall by giving a damping function will not be caused.

  As described above, according to the turnbuckle 20 of the second embodiment, the earthquake-proof reinforcement of the house can be performed by a procedure substantially similar to the reinforcement procedure for the shaking of the house due to the conventional turnbuckle without causing a decrease in strength. Therefore, it is suitable for seismic reinforcement of existing wooden houses that require rapid construction.

  The present invention can be applied to a house that requires seismic reinforcement, in particular, a wooden house.
