Abstract

PROBLEM TO BE SOLVED: To provide a base isolation structure which reduces a vibration relating to a house, structural object and an equipment in an earthquake by combination of laminated leaf springs and steel balls. SOLUTION: A coil spring 2 of steel ball or superalloy iron ball 1 and a laminated leaf spring 3 are combined and arranged in a lattice iron plate 5, angle iron plate 6 and a framed iron plate 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an exemption from damage and destruction of houses such as two-story wooden buildings or railways, structures such as highway piers, and computers, televisions, etc. against earthquakes. It is a quake structure.

[0002]

2. Description of the Related Art In the case of a conventional wooden two-story house, four pillars at the four corners, which are basic, are mainly used and two to six auxiliary pillars are installed in the middle. In particular, the roof tiles are very heavy, and the weight of the roof is applied to the base of the four pillars. During an earthquake, the vibration concentrates and it is loaded and broken into weak places and collapses from the first floor.

[0003]

[Problems to be Solved by the Invention] In the occurrence of an earthquake, a strong vibration instantaneously causes upper, lower, left, right, and swaying motions to collapse structures on the ground. The present invention has been made to solve the above drawbacks.

[0004]

[Means for Solving the Problems] The present invention can
The sway of the left and right is controlled by the coil spring (Figs. 1 and 2) and the leaf spring (Figs. 1 and 3). According to the combination of (Figs. 1 and 2). The present invention is an earthquake-resistant two-story floor having the above-mentioned configuration.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION When the seismic isolation structure of the present invention is used, wooden houses, structures and equipment, etc. are prevented from being damaged by vibrations caused by upper and lower shaking and left and right shaking, The damage can be minimized.

[0006]

Embodiments of the present invention will be described below. (A) As shown in FIG. 5 (perspective view), the ground part and the second floor part are divided by iron plates (5), (6), and (7). This iron plate is (5) in FIG. 3 (perspective view). A lattice iron plate (6), a square iron plate (7), and an iron plate with a frame. (B) Coil springs (Fig. 1,
2) and leaf spring (Figs. 1 and 3) in Fig. 2 (plan view)
(B) Set the coil springs and leaf springs as shown in the layout diagram. (C) The left, right, and swaying caused by the earthquake are shown in Fig. 2 with steel balls or superalloy balls (Fig. 1, 1) and coil springs (Fig. 1, 2).
(Plan view) (B) Iron ball (steel ball or superalloy ball), coil spring, set as shown in the layout. (D) The wiring and piping of the lifeline electricity, telephone, gas, tap water, etc. associated with the separation of the first-floor ground part and the second-floor part by iron plates are three iron plates 5-lattice iron plates, 6 in FIG. -Square iron plate, 7-Through the iron pipes with frame, through the pipes at the four corners, the width of the earthquake is 50cm-100cm.
Cooperate considering left and right. (E) In addition, the stairs (Fig. 4) are equipped with a combination of small coil springs and iron balls to reduce shaking. (G) Steel balls or superalloy balls are used for lightweight facilities such as stairs, and iron balls are used for light-weight facilities. In the case of the first and second floors of a wooden 2-story house (Fig. Since the weight of the first floor is higher than that of the second floor, the size of the sphere and the content of the material change from iron balls to steel balls to superalloy balls due to the difference in weight. The present invention has the above configuration. When the present invention is used, the vibration of an earthquake is propagated separately to the ground portion on the first floor and the portion on the second floor, so the damage is very small and the disaster is prevented. In addition to the above, the present invention is applied to railways, highway piers, and constructions such as factories and fences as shown in FIG. 6, and to earthquake-prevention blocks such as computers and televisions as shown in FIG. Can be spared the damage of.

[0007]

EFFECTS OF THE INVENTION By using the present invention, a house, a structure, a device, etc. are prevented from being shaken by an earthquake, and the collapse thereof is prevented.

Claims (1)

[Claims] 1. A vibration of a house, a structure, equipment, etc. in an earthquake caused by a coil spring (FIGS. 1 and 2), a leaf spring (FIGS. 1 and 3) and a steel ball or a superalloy ball (FIGS. 1 and 1). This is a seismic-resistant two-story floor that incorporates a seismic isolation structure that is reduced by the combination of.
