Description

  The present invention relates to a structure of a stiffener attached to a column in order to prevent the column from shaking in a combined structure of a girder and a column of a building.

  Currently, in a wooden house or a light steel frame house, in order to reduce the shaking of the column during an earthquake, a completely rigid strut is used.

Indication of invention

Problems to be Solved by the Invention

  In order to prevent the column from swaying during an earthquake, it is necessary to impart some elastic elongation to the struts so that the struts retain their full tension at the end of the stretch. The present invention seeks to solve this method.

  In the structure of the disc spring compression apparatus 2 designed to be incorporated in the building brace 1 according to the present invention, two heavy load disc springs 9 are stacked in an abacus shape, and several to a dozen sets are overlaid. A bifurcated tension member 12 with a washer receiving projection, to which a washer 11 is attached in order to maintain a required bending allowance in combination with a strong compressive force as the spring group 7, and to convert the compressive force into a strong tensile force; After the bifurcated tensile material 14 without projections is combined with the bifurcated one another, these are inserted into the central hole 8 of the disc spring group 7, and the cylindrical ring 16 is made small at the end of the bifurcated tensile material 14 without projections. The disc spring compression device 2 is formed by fixing with bolts 17 or the like, and the bolts 13 and 15 at both ends are connected to each other and incorporated in the stiffener 1 and pulled by an external force such as an earthquake, the tensile force is Supported by the strong pressing force of the disc spring group 7 in the spring compression device 2, Once tensioned by preventing ring 10 deflection is sandwiched between the disc spring 9 deflection of the disc spring population 7, incorporating Belleville spring compression apparatus 2 so as to be prevented is the structure of the building muscle differences.

  In the structure of the disc spring compression device 2, instead of inserting and combining the bifurcated tensile material 12 with a washer receiving projection and the bifurcated tensile material 14 without a projection into the central hole 8 of the disc spring group 7, The rod-shaped tension member 18 and the rod-shaped tension member 21 are inserted therein, and the cylindrical ring 16 is fixed to the rod-shaped tension member 21 with a small bolt 17 or the like to form the disc spring compression device 2.

Effect of the invention

  According to the present invention, the building is slightly deformed at the time of the earthquake, but further deformation is prevented by the struggle, the collapse of the building can be avoided, and the building returns to the current state when the shaking is settled.

As an example of implementation of the present invention, a front view of a building stiffener with a spring compression device attached The longitudinal cross-sectional view of the spring compression apparatus of an example of implementation of this invention Left side view of FIG. AA sectional view of FIG. The longitudinal cross-sectional view of the spring compression apparatus of an example different from FIG. 2 of an example of implementation of this invention BB sectional view of FIG.

  In wooden houses or lightweight steel houses, in order to reduce the shaking of the columns at the time of an earthquake, it is necessary to limit the shaking with a slight difference in stretch, as shown in FIG. When the column 5 is tilted due to an earthquake, the brace 1 attached obliquely to the column is pulled. Since the disc 1 has a disc spring compression device 2 incorporated therein, the column 5 is pulled by the disc spring compression device 2. In this case, all the disc springs 9 of the disc spring compression device 2 are compressed and bent to absorb the energy of the vibration, and the disc is placed on the anti-bending ring 10 sandwiched between the disc springs 9. When the inner surface of the spring 9 comes into contact, the tension allowance of the disc spring compression device 2 is eliminated, so that the strut 1 does not extend any further, and therefore the inclination of the column 5 is prevented, and when the swing is settled, the column 5 is Repulsive force of the disc spring 9 of the disc spring compression device 2 It is returned to a more original state.

  A large number of heavy load Belleville springs 9 of the Belleville spring compression device 2 are stacked in a abacus ball shape, and several to a dozen sets of these are piled up as a Belleville spring group 7 together with a strong compression force and required. A bifurcated tensile member 12 with a washer receiving projection, to which a washer 11 is attached, and a bifurcated tensile member 14 without a projection, which are capable of holding a bending allowance and converting the compression force into a strong tensile force, are bifurcated. Are inserted into the central hole 8 of the disc spring group 7, and the disc ring compression device 2 is fixed by fixing the cylindrical ring 16 with a small bolt 17 or the like at the tip of the bifurcated tension member 14 without projections. When the bolts 13 and 15 at both ends are connected and incorporated into the brace 1 and pulled by an external force such as an earthquake, the tensile force is applied to the strong force of the disc spring group 7 in the disc spring compression device 2. It is supported by the pressing force and is further sandwiched between the disc springs 9 when pulled. Preventing ring 10 flex, incorporating Belleville spring compression apparatus 2 deflection of the disc spring population 7 is to be prevented building muscle structure differences.

  In the structure of the disc spring compression device 2, instead of inserting and combining the bifurcated tensile material 12 with a washer receiving projection and the bifurcated tensile material 14 without a projection into the central hole 8 of the disc spring group 7, The rod-shaped tension member 18 and the rod-shaped tension member 21 are inserted, and the cylindrical ring 16 is fixed to the rod-shaped tension member 21 with a bolt 17 or the like to form the disc spring compression device 2.

In the present invention, a strong pressing force can be obtained only by using a disc spring 9 without using a coil spring as a spring built in the expansion / contraction device. By overlapping 10 to 10 pairs, a sufficient allowance can be obtained.
As an example, when the heavy load disc spring has an outer diameter of 40 mm and an inner diameter of 20 mm and a thickness of 2.2 mm, it can withstand a compression load of about 600 kg, and the allowable deflection in the case of 14 disc springs, that is, seven sets, is about 10 mm. Sufficient strength and bending allowance can be maintained.
