Description

  The present invention relates to the structure of a vibration reduction device for a small building, and more particularly to the structure of an economical and small earthquake vibration reduction device. It has the advantages of low cost, convenient installation and easy maintenance. Mainly fixed at the corners of beams and pillars of buildings by hydraulic dampers and joints, effectively relieving the displacement and deformation of buildings due to the energy of earthquakes.

In the country or area located in the earthquake zone, I feel deeply intimidated and fearless when the earthquake threatens life and property. When an earthquake occurs, the earth's surface is displaced by changes in the strata, and the moving energy affects the structure of the building.
If the strength of the building is insufficient to resist the energy generated by the vibration, the structure of the building is destroyed. If the damage is light, it will crack and deform, and if it is heavy, it will collapse. Therefore, how to reduce or eliminate the damage that earthquakes cause to buildings is an important issue that each field is investigating. Various devices and equipment aimed at eliminating the energy of earthquakes have been designed and invented, but these devices include a shock absorbing component that absorbs or transfers energy substantially. When the building is subjected to vibrations, the device is installed on a part of a structure that is easily destroyed or on a building site of a combined building. A damper such as a spring, a rubber product, or a hydraulic pressure cylinder is widely used as the above-described cushioning component. For example, there are Taiwan Patent Application No. 144963 “Hydraulic Buffer Sheet for Buildings” and Patent Application No. 365269 “Building Vibration Absorption Structure”. However, the proposed patent application shows a relatively large energy erase design. The structure of the apparatus is relatively complicated, and the design plan or the installation location of the building must be determined in advance before the building is put into practice, resulting in various problems such as high cost and difficulty in installation. The object of the present invention is a wooden building and a small building with a small number of floors, and provides an economical and miniaturized earthquake vibration reduction device, which has the advantages of low cost, convenient installation and easy maintenance. The Taiwanese patent application draft M259811 “Building seismic isolation device” (see FIG. 1) mainly comprises a hydraulic damper 10 and two joints 11. Both ends of the hydraulic damper 10 are connected to joints 11, respectively, and the two joints 11 are fixed to the corners of the beams and columns of the building, respectively. If an earthquake occurs and the beam and column are deformed and deformed, the hydraulic damper 10 generates buffer energy by fixing the two joints 11, and the structure of the beam and column of the building is generated by the earthquake vibration. Buffer the destruction.

The above-mentioned patent application proposal “building seismic isolation device” certainly has a certain effect on the deformation of building beams and columns. However, when the building is shaken by vibration, the bending angle of the beam and column of the building generates a lateral movement force (that is, a lateral force is generated between the beam and the column as shown in FIG. 2). When a lateral force is generated in a small building (especially a wooden house where beams and columns are made of clasps) and the beam and columns are displaced upward and deformed, the proposed patent application `` Building avoidance '' Since the seismic device does not have enough restraining force in that direction, the beam is displaced upward as shown in FIG. Therefore, it was still necessary to improve the effect of eliminating the seismic energy of the “building seismic isolator” for a small building.

  The object of the present invention is to provide an economical seismic vibration reduction device, which has the advantages of low cost, convenient installation and easy maintenance. In particular, the main task is to eliminate the lateral force acting on the beams and columns of seismic energy and improve the effect of seismic reduction.

  In order to solve the above problems, the present invention is composed of a damper and a fixed base. The damper comprises an outer cylinder and a piston, and the end of the outer cylinder and the tip of the piston are connected. The fixing base is composed of a first fixing sheet and a second fixing sheet, and the connecting ends of the first fixing sheet and the second fixing sheet form shaft points by passing the shaft, and the first fixing sheet and the second fixing sheet Convex wings are provided at the outer ends, respectively, and the connecting end of the damper corresponds to the convex wing, and the damper is installed between them via the shaft. By fixing the fixed base at the corners between the beams and pillars of the building, the structure of the building is effectively relieved from being displaced or deformed by the seismic energy.

The present invention has the advantage that the installation of the damper and the fixed base eliminates the lateral force acting on the beams and pillars of the seismic energy in particular and improves the effect of the vibration reduction, and at the same time has low cost, convenient installation and easy maintenance.

  In order to clearly show the structure of the vibration reduction device for a small building according to the present invention, a detailed description will be given with reference to the drawings. As shown in FIG. 4, the present invention mainly includes a damper 20 and a fixed base 30. The damper 20 (see FIGS. 4 and 5) includes an outer cylinder 21 and a piston 22, and the piston 22 operates slowly by filling the outer cylinder 21 with oil, gas, or a mixture thereof at an appropriate pressure. Has a damping force. The end of the outer cylinder 21 is a coupling end, and a coupling hole 23 is provided. The upper end of the piston 22 is a coupling end, and a coupling hole 24 is also provided.

  The fixing base 30 (see FIGS. 4 and 5) is constituted by a first fixing sheet 31 and a second fixing sheet 32. The first fixed sheet 31 and the second fixed sheet 32 are sheets having the same shape, and are coupled symmetrically. A shaft hole 33 is provided at the coupling end of the first fixed sheet 31 and the second fixed sheet 32, and a shaft point is formed by passing the shaft 34 through the two shaft holes 33. The first fixed sheet 31 and the second fixed sheet 32 can change the angle through it. By installing an elastic rubber ring 35 (or rubber pipe) between the shaft 34 and the shaft hole 33, an appropriate expansion / contraction space is provided between the first fixed sheet 31 and the second fixed sheet 32. Convex wings 36 are provided on the outer sides of the first fixed sheet 31 and the second fixed sheet 32, and holes 37 are provided on the convex wings 36. The coupling holes 23 and 24 of the damper 20 correspond to the two holes 37, and the damper 20 is installed between them via the shaft 38.

  FIG. 6 shows that the first fixing sheet 31 and the second fixing sheet 32 of the fixing base 31 are set at the corners of the building needle and the pillar, respectively, after the damper 20 is installed on the fixing base 30 through the above-described structure. Fix it. It has a role to reinforce the strength of the building by increasing the support of the damper 20 between the beams and pillars of the building. When energy due to seismic force is injected into the damper 20, the medium (oil, gas or mixture thereof) filled in the outer cylinder 21 plays a role of buffering the external force, so that the seismic energy is delayed and the seismic force Eliminates or relaxes the destruction that the building gives to the building.

  In addition, when beams and columns are destroyed, the strength of the building structure is greatly reduced, and a problem arises in the force of the building materials to support each other. It is most important in the whole structure to avoid the destruction of the connection points of beams and columns due to seismic forces in the area of earthquake reduction in buildings. The best installation position of the present invention is the corner of a building beam or column. However, since the structural installation restrictions of the present invention are small and the assembly is simple, it can be installed between a beam (column) and a wall or between a wall and a floor (ceiling) based on needs. In addition, wooden structures are the most common type of joint where beams and columns are susceptible to earthquake damage. When a wooden building is shaken due to vibration, the bending angle of beams and columns causes a horizontal lateral force, so that it moves upward while the beam is shaking. However, the fixed base 30 of the present invention has an L-shaped connection design and has a role of effectively restraining upward deformation between the beam and the column. Therefore, the best use place of the present invention is wooden construction. It can also be used for small buildings of brick or concrete structure, and similarly reaches the purpose of distributing seismic energy and increasing the seismic capacity of the structure. Furthermore, an elastic rubber ring 35 (or a rubber pipe) is installed between the shaft 34 and the shaft hole 33 of the fixing base 30 of the present invention, so that it is appropriate between the first fixing sheet 31 and the second fixing sheet 32. The elastic space has an auxiliary effect of buffering seismic energy.

  In the present invention, the damper 20 and the fixed base 30 have a structure that, when installed in a small building, the damper 20 has a buffering effect against the displacement deformation of the building due to the seismic energy. At the same time, the present invention has a reinforcing effect on the strength of the building. The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. Those who are familiar with this technology can make appropriate changes and adjustments, such as changes in the fixing structure, and these changes and adjustments do not lose the significance of the present invention and are included in the scope of the present invention.
