JPS5881248A - Anti-quake installation member - Google Patents

Abstract

PURPOSE:To prevent vibration, movement and tumble of an installation by combining the upper member provided with a boss horizontally below the table with the lower member provided with a projection for the purpose of engagement with the above-mentioned boss through a non-linear elastic substance. CONSTITUTION:An anti-quake installation member is formed by interposing a non-linear elastic substance 3 made of neoprene etc. between the upper 1 and lower 2 members, where the upper member 1 is equipped with a table 4 for placing necessary apparatus and two or more bosses 5 protruding outward from this table 4 at an appropriate spacing. The lower member 2 is furnished with a bottom plate 6 for installation on the floor and a flange 8 protruding inward from this plate 6 at a certain spacing with a cylinder 7 interposed. This flange 8 is provided with a recess 8a and a projection 8b for engagement with said bosses 5. Thereby vibrations of the installation can be suppressed as well as movement and tumble prevented in the event of an earthquake etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an earthquake-resistant installation member used for installing equipment.

In recent years, with the modernization of the living environment, some of the equipment housed inside building structures is rigid.In order to operate these equipment effectively and maintain safety, vibration prevention and earthquake prevention measures are required. Sufficient consideration must be given to the installation, including taking countermeasures. Particularly recently, in preparation for the occurrence of a major earthquake, all kinds of disaster prevention measures are being considered and implemented in various fields.

However, these measures not only affect the welfare of the building structure, but also
Preventing secondary damage to humans due to equipment movement or falling during an earthquake can be said to be a condition for supplying equipment.

The present invention has been made in view of the above points, and it prevents vibrations caused by the operation of an air conditioner from being transmitted to a building when installing a package of equipment such as an air conditioner, and also prevents movement or overturning in the event of an earthquake. The object of the present invention is to provide an earthquake-resistant installation member that also has vibration isolation that can reliably prevent disasters.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view, FIG. 2 is a bottom view of the lower hardware, FIG. 3 is a plan view of the lower hardware, and FIG. 4 is a load-deflection diagram of linear rubber and non-linear rubber.

The earthquake-resistant installation member of the present invention has a non-linear elastic body (hereinafter referred to as non-linear rubber) 3 made of neoprene, urethane, etc. interposed between a lower metal fitting 1 and a lower metal fitting 2, as shown in FIGS. 1 to 3. It is something.

That is, the lower hardware 1 is a pedestal section 4 on which equipment is placed.
It has a plurality of (4 in this embodiment) protrusions 5 that protrude outward from this pedestal part 4 at appropriate intervals, and the lower hardware 2 is installed on the floor. bottom plate part 67 for
Seven rung parts 8 are provided at appropriate intervals from the bottom plate part 6 and project inward from the cylindrical part 6, and a recess 8a into which the protrusion part 5 of the metal stopper l can be fitted. Therefore, a convex portion 8b with which the protruding portion 5 can engage is also formed in a planar manner. Note that 9 is a mounting hole for equipment, and 10 is a mounting hole for the floor.

To assemble, place the non-linear rubber 3 in the center of the lower metal fitting 2, and insert the protrusion 5 of the metal stopper 1 into the lower metal fitting 207 and the flange part 8.
After fitting into the concave part 8a, the stopper 1 and the lower part 2 are rotated 1/8 relative to each other, and the protrusions 6 and 7 are fitted into the convex part 8 of the rung part 8.
(See Figure 1).

The reason why non-linear rubber is used in the present invention is to reduce vertical dimensional changes due to changes in the load of equipment. □″ □′ In other words, the pedestal 4 deforms in the vertical direction due to differences in load points such as the center of gravity of the equipment, but this is to minimize the degree of deformation.This also makes it easier to install the equipment. This is useful for keeping it level when doing so.

The load-deflection diagram in FIG. 4 was derived experimentally. As can be seen from this figure, when the same load W is applied, when comparing the amount of deflection a of linear rubber A and the amount of deflection of non-linear rubber B, it is &>b, and non-linear rubber B has a greater amount of deformation. is small.

The above explanation has mainly been about the vibration isolation and seismic effects of equipment in the vertical direction, but in the case of an earthquake, a considerable horizontal force is applied, and the nonlinear rubber 3 alone may not be able to absorb the vibrations. In this case, the present invention has a structure in which the stopper 1 and the lower metal fitting 2 engage with each other to function as a stopper, so that the effects of side-slip prevention and fall prevention can be fully exhibited.

The fasteners and lower hardware are manufactured from ferrous castings such as gray cast iron, ductile cast iron, and double-kneeler cast iron, or from non-ferrous castings such as aluminum alloy and copper alloy. It may be manufactured by

As mentioned above, the earthquake-resistant installation member of the present invention is a combination of a stopper and a lower metal fitting that can be engaged with each other in the vertical and horizontal directions through non-linear rubber, so that the size of the equipment to be mounted can be reduced. By determining the dimensions and shape of the upper and lower hardware and non-linear rubber according to the weight, etc., it is possible to prevent vibration in the vertical direction. It is something that can be prevented.
