Description

[Detailed description of the invention] [Industrial field of application] The present invention is an improvement of a level-adjustable joistless vibrationproof floor, and more specifically, an improvement of the level-adjustable joistless vibrationproof floor. By cleverly modifying the shape of the vibration isolator to increase the shock-absorbing deformation function of the vibration isolator compared to the floor post vibration isolators that are placed close to the walls and thresholds around the room, the shock-absorbing function can be improved.・Good sound insulation performance,
Moreover, it relates to a stable floor support structure around the room of a level-adjustable floor that is easy to install and does not lower the floor level around the room, and does not lower the floor level around the room. ,
It can be used for floor structures in housing complexes such as apartments and condominiums, and even in gymnasiums.

[Conventional technology and problems to be solved]

A level-adjustable joy stress vibration-isolating floor in which a floor plate is supported by a floor post with an adjustable vibration-isolating body consisting of a floor support nut and a support bolt screwed into the nut is well known. The present applicant has also received numerous patents and utility model registrations for the Joyostress vibration isolation floor of this method (for example, see Figure 15 of Japanese Patent Publication No. 61-27544).

By the way, the problem with vibration-proof floors with such a structure is that if the hardness of the vibration-proof material is lowered in order to improve sound insulation performance, it will cause damage to areas near walls where furniture such as chests of drawers, bookshelves, refrigerators, and indoor equipment are installed. There was a need for a way to prevent the floor level from sinking, and the floor near the doorway threshold sinking and creaking every time people entered and exited the building.

In response to such requests, the present inventor previously tried a method in which the rubber hardness of the vibration isolator was made harder in the area around the room than in the inner area. However, in this method, at least two types of vibration isolators are prepared: a hard vibration isolator with high rubber hardness and a soft vibration isolator with low rubber hardness,
It is necessary to distinguish between the room surrounding area and the internal area and use them accordingly.If you try to visually identify these vibration isolators with different hardness differences and place the floor post in the appropriate place, The work load at the floor construction site becomes too heavy, and sometimes mistakes are made, such as placing hard vibration isolators in the inner area and soft vibration isolators around the room. Arranging things to do so was definitely idealistic, and in reality things did not go as planned.

This invention solves the above-mentioned difficulty (lowering of the floor level) in the conventional level-adjustable joy stress vibration-isolating floor.
In addition to solving this problem, we went one step further to create stable floor support around the room, which has good sound insulation performance and can be easily installed by correctly using floor posts without causing misunderstandings by on-site workers. The technical problem is to provide a level-adjustable joy stress vibration isolation floor.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above technical problem will be explained with reference to the attached drawings.
It is as follows.

That is, in the present invention, the floorboards 1, 1... spread indoors are supported by freely adjustable floor posts 2, 2... consisting of a floor support nut 21 and a support bolt 22 screwed into the nut. This is based on the technical premise of the conventionally well-known level-adjustable joy stress vibration isolation floor, and on this technical premise, the support bolts 2 of the floor posts 2, 2...
2, 22... are formed into a cylindrical shape, and a rubber-like vibration isolator 3 is attached to the lower end of these support bolts 22,
In addition, by forming bullet-increasing notches 31 in each of the vibration isolators 3 of the floor posts 2, 2, etc., which are installed in the interior areas other than the areas close to the room, such as near walls and thresholds, The most distinctive feature is that it employs technology that allows for easy deformation and easy identification from the outside.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on an illustrated embodiment. In addition, Fig. 1 is an explanatory diagram showing the external appearance of a vibration isolator that is an embodiment of the present invention, and Fig. 2 is a cross-sectional view of the lower part of a floor post used near the area around the room near the wall and threshold. A sectional view of the main parts shown,
FIG. 3 is a cross-sectional view of the main part of the lower part of the floor post used in the inner area of the room.

In the drawings, what is indicated by the reference numeral 1 is the floorboard, on which are installed the sillage board and the floor finishing board (none of them are given a reference numeral).

The reference numeral 2 designates a floor post whose height can be adjusted freely, and in this embodiment, one made of injection molded synthetic resin (nylon) is used. This floor post 2 is composed of an inverted dish-shaped floor support nut 21 fixed to the lower surface of the floor plate 1; and a support bolt 22 that is screwed into a female threaded hole of the floor support nut so that it can be rotated in forward and reverse directions. ing.

Also, what is designated by the reference numeral 3 is a rubber-like vibration isolator, which is a support bolt 22 of the floor post 2.
It is attached to the bottom of the. The rubber-like vibration isolator 3 is formed into a block having a central shaft hole 32 through which the support bolt 22 passes, and is made of synthetic rubber material in this embodiment.

The biggest feature of the present invention lies in the shape of the vibration isolator 3. In this embodiment as well, the vibration isolator 3 of the floor post 2 installed in the inner area of the floor has an increased number of bullets on its circumferential surface. By forming the notch 31, the rubber hardness does not need to be lowered to facilitate cushioning and deformation. The vibration isolators 3 of the floor posts 2, 2, . The location of use can be clearly identified at first glance by the presence or absence of 31.

The vibration isolation floor of this example is roughly as described above, but
The present invention is by no means limited to the above-mentioned embodiments, and various design changes are possible within the scope of the "Utility Model Registration Claims". The shape of the vibration isolator 3 is changed to the shape shown in Figures 4 to 6, and the color of the vibration isolator 3 of the inner floor area is changed to match the vibration isolator of the floor post used in the outer area. It goes without saying that the distinction between the color of the body 3 and the color of the body 3 is planned to be changed as appropriate depending on specific design requirements, and is within the technical scope of the present invention.

[Effects of this invention]

As explained above with the examples, in the case of the joy stress vibration isolating floor constructed by applying the present invention, the vibration isolators of the floor posts in the outside area of the floor near the room, such as near the wall and the threshold, are as follows: Since it does not have bullet holes, it has strong deformation resistance and supports the bottom end of the floor post firmly, so even if heavy furniture such as chests of drawers or bookshelves is installed near a wall, the floor level there will sink or the doorway and Even if people enter and exit near the threshold,
There is no inconvenience such as squeaking or squeaking, and since the vibration isolator of the floor post installed in the inner area of the floor has a bullet-increasing notch, it is easy to buffer deformation. It also has very good vibration resistance, stability and sound insulation.

In addition, the Joystress vibration-isolating floor of the present invention imposes a burden on on-site work, as it forces discrimination of rubber hardness differences only by appearance and feel, as in the previously tried method using two types of hard and soft vibration isolators. Since there is no problem of increase in size and it is extremely easy to identify visually, it can be said that the workability is also very good.

As described above, according to the present invention, in addition to being able to solve all of the problems that were conventionally considered to be problems with this type of joy stress vibration isolation floor, its practical value is that it does not impair its construction efficiency in any way. It's really big.
