Description

  The present invention relates to a reinforcing structure for a hook suitable for use in reinforcing an existing block hook, for example.

  Traditionally, when a large earthquake occurred, the existing block wall collapsed, causing a disastrous accident.

  For this reason, the current seismic standards for block fences are stipulated by the revision of the Building Standards Law Enforcement Order in 1981 so that they will not collapse even if an earthquake with a seismic intensity of 6 to 7 occurs.

  For example, Patent Document 1 proposes a structure of a block rod provided with braces to increase the seismic strength so as to conform to the seismic standards.

  However, in practice, there are still a large number of block walls that do not meet the earthquake resistance standards. From the standpoint of safety, it is desirable to remove these block fences and rebuild them that meet the seismic standards.

Japanese Utility Model Publication No. 58-162944

  However, considering the economic costs required to reconstruct the block fence, the shortage of manpower at the construction site, the reuse of materials (blocks, etc.), reinforcing the existing block fence is also a realistic option. .

  This invention is made | formed in view of such a condition, and it aims at enabling it to reinforce the existing block rod with a simpler structure.

  The present invention includes a plurality of means for solving at least a part of the above-described problems. Examples of such means are as follows. In order to solve the above-described problem, a reinforcing structure for a scissors according to an aspect of the present invention includes a plurality of pillars having a predetermined distance from the scissors and having one end fixed to the ground on one of the front side or the back side of the scissors. And a plurality of beams combined with the plurality of columns in a lattice shape, and a plurality of reinforcing bars each having one end locked to the hook and the other end fixed in the vicinity of the intersection of the columns and the beam. It is characterized by that.

  The reinforcing bar can penetrate the heel from the other side of the front side or the back side of the heel.

  The reinforcing bar may have a tip portion that locks the hook at one end.

  According to the present invention, an existing block rod can be reinforced with a simpler structure.

  Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

<Reinforcing structure of block cage which is one embodiment according to the present invention>
FIG. 1 is a cross-sectional view showing an example of a reinforcing structure 20 for a block rod according to an embodiment of the present invention. FIG. 2 is a view showing an example when the reinforcing structure 20 of FIG. 1 is viewed from the back side of the block cage 10. FIG. 3 is a diagram illustrating an example when the reinforcing structure 20 of FIG. 1 is viewed from the front side of the block rod 10.

  The reinforcement structure 20 is for reinforcing the seismic strength of the block cage 10 by performing additional construction on the existing block cage 10.

  In the block cage 10, a plurality of blocks 11 are stacked on the base portion 12. The foundation portion 12 is made of concrete, for example, and most of the foundation portion 12 is buried under the ground surface 13. In the block 11, vertical reinforcing bars 14 reaching the base portion 12 are provided in the vertical direction at predetermined intervals. Further, the horizontal reinforcing bars 15 are provided in the block 11 in the horizontal direction at predetermined intervals.

  The reinforcement structure 20 to be additionally applied to the block fence 10 has a predetermined distance from the block fence 10 on the back side of the block fence 10 (for example, the building side when the block fence 10 is between the building and the road). Installed in the open. The reinforcing structure 20 may be installed on the front side of the block fence 10 (for example, on the road side when the block fence 10 is between the building and the road).

  The reinforcing structure 20 is configured by combining a plurality of columns 21 and a plurality of beams 22 in a lattice shape. The column 21 and the beam 22 are fixed to each other by a clamp (fastening hardware) 25. The column 21 and the beam 22 are made of, for example, a steel pipe having a diameter of 50 mm. For example, five columns 21 are arranged per 10 m of the horizontal width of the block cage 10. The column 21 is embedded in the ground for a predetermined length (for example, 600 to 700 mm) or more, and is fixed on the ground surface 13 by a root winding concrete 26 having a diameter of about 300 mm. For example, the beams 22 are arranged in two stages at a predetermined interval. For example, zinc plating is applied to the surfaces of the columns 21 and the beams 22 as a rust prevention treatment.

  Furthermore, the other end of the reinforcing bar 23 penetrating the block 11 via the washer 27 (FIG. 3) reaches the vicinity of the intersection of the column 21 and the beam 22. The reinforcing bar 23 is made of, for example, a reinforcing bar having a diameter of 13 mm, and its surface is painted as a rust prevention treatment. A rebar with a diameter of 13 mm has a tensile force of 10 t or more. The tip 24 provided at one end of the reinforcing bar 23 is formed larger than the diameter of the reinforcing bar 23 (13 mm in this case) so that the reinforcing bar 23 does not come out to the back side of the block rod 10. Yes. Thereby, one end of the reinforcing bar 23 is locked to the block 11 constituting the block rod 10 by the tip end portion 24.

  On the other hand, the other end of the reinforcing bar 23 is fixed to a clamp 25 that fixes the column 21 and the beam 22.

  According to the reinforcing structure 20 configured as described above, even if the block cage 10 vibrates due to the occurrence of an earthquake and is about to collapse to the front side (right side in FIG. 1), the reinforcing bars 23 penetrating the block 11 are 10 t or more. Since the block rod 10 is supported by the pulling force, the collapse of the block rod 10 to the front side can be suppressed.

  Further, according to the reinforcing structure 20, as shown in FIG. 3, only the front end portion 24 of the reinforcing bar 23 and the washer 27 appear on the front side of the block rod 10, and the current state of the front side of the block rod 10 is shown. Can be substantially maintained. Thereby, for example, a picture or the like drawn as a graduation commemoration on the front side of the block fence 10 installed in an elementary school or the like can be stored even after the reinforcement structure 20 is constructed.

  In addition, since the reinforcement structure 20 is a simple structure, it can be constructed economically at low cost. In addition, since the process is easy, even a craftsman with a small number of people and work experience can perform the construction. Furthermore, since the existing block wall 10 is used as it is without collapsing, it is advantageous from the viewpoint of material reuse.

  In addition, the numerical value quoted in embodiment mentioned above is an example, and does not limit this invention. For example, the number, material, diameter, and the like of the columns 21, the beams 22, and the reinforcing bars 23 can be arbitrarily changed.

  Further, the present invention can be applied not only when reinforcing a block fence, but also when reinforcing a fence made of laminated bricks, wood, stones, and the like.

  In the above-described embodiment, the configuration has been described in detail for easy understanding of the present invention, and is not necessarily limited to the one having all the configurations described.
