Description

[Detailed description of the invention] The present invention consists of a member for placing and supporting the edge of a panel-shaped floor member, and a height adjuster with a vibration isolator interposed between the supporting member and the structural floor slab. The present invention relates to a vibration-proof floating floor support device comprising:

In the conventional type, the supporting member is composed of a single plate-shaped body whose entire surface is flat, and in order to fix the panel-shaped floor member placed on the top surface of this plate-shaped body, holes formed in this plate-shaped body are used. The screws were screwed into the floor component from below.

In this case, the work efficiency is poor because the worker has to crawl under the floor member, and since the connection between the supporting member and the floor member relies only on screws, the screws are sheared due to horizontal external force and vertical vibration Connection strength decreases over time due to external forces concentrating on the screws, such as wear on the screw threads.
It had the disadvantage of being prone to rattling.

The support device for a vibration-proof floating floor according to the present invention has been developed in view of the above circumstances, and has the above-mentioned configuration, wherein the support member includes a horizontal plate portion that contacts or is close to the upper surface of the edge of the floor member. ,
The edge portion of the floor member is integrally connected between the horizontal plate portion and the support member in a state that it can be inserted from the lateral side, and the horizontal plate portion is provided with a fastener insertion hole. It is characterized by

That is, after inserting the edge of the floor member between the horizontal plate part and the support member, it is possible to apply the fastening tool to the floor member from above through the insertion hole of the horizontal plate part, which is different from the conventional method. This eliminates the need for the operator to crawl under the floor members, and the connection work can be quickly and easily performed above the floor members.

In addition, among the external forces that act between the support member and the floor member, the horizontal external force is countered by the above-mentioned fasteners, while the vertical vibration is counteracted by the support member that holds the floor member from above and below, and the horizontal They can be divided in such a way that they are opposed to the plate part.

Moreover, it is not a simple distribution; in the horizontal direction, the resistance force due to the penetration of the fastener into the floor member and the sliding friction resistance of the support member and the horizontal plate against the floor member combine, and in the vertical direction, the Since the drag force that prevents the dressing from coming off against the floor member and the clamping force created by the cooperation between the support member and the horizontal member work together, the strength of the connection between the support member and the floor member can be greatly increased compared to conventional devices. Moreover, the connection effect with this great strength can be maintained reliably and favorably for a long period of time.

Therefore, the device of the present invention is extremely effective as a vibration-proof floating floor support device for buildings in areas subject to severe vibrations, such as near elevated roads and railways.

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 1, this support device A supports panel-shaped floor members 7, which are arranged above a structural floor slab B in both vertical and horizontal directions, on the floor slab B. A member a for mounting and supporting the edge portion, and a height adjustment tool with a vibration isolator C interposed between the support member a and the structural floor slab B,
In addition, the support member a has a horizontal plate part 1 that contacts or is close to the upper surface of the edge of the floor member 7 placed thereon, and an end of the floor member 7 between the horizontal plate part 1 and the support member a. The horizontal plate part 1 is integrally connected to the lower end of the vertical plate part 2 which is bent downward from the inner end of the horizontal plate part 1 so that the edge can be inserted from the side. The basic configuration is that a through hole 1a for a fastener 4 such as a screw is formed in the hole 1a.

The supporting member a and the horizontal plate part 1 are of a four-way type, a two-way type, and a one-way type, depending on the mode of action on the floor member 7.
There are three types.

The four-way type supports four floor members 7 at the same time by fitting them at their respective corners, and as shown in Fig. It has a horizontal plate part 1, and each horizontal plate part 1 has a board part 2 which is lowered from its two sides.
is bent.

The two-way type is for fitting and supporting two floor members 7 at the same time, and has horizontal plate portions 1 on both sides of the connecting portion 3 as shown in FIG.

The two-way type is a type that fits and supports the wall side or corner of the floor member 7 located in the corner of the room (not only an inside corner, but also an outside corner due to going to work, a closet, etc.). It looks like this.

Regardless of the type, the height adjustment tool generally has the same configuration, for example, a right or left threaded part that screws into the connecting part 3 of the support member a and a part that covers the vibration isolating material C. A male threaded member 6 is provided with a left or right threaded portion on both upper and lower sides thereof to be screwed into the cylindrical portion 5A of the pedestal 5 to which the crown is fixed, and a groove formed at the upper end to engage a driver from above through the connecting portion 3. It is preferable to use a turnbuckle type, such as the one equipped with a turnbuckle, since it allows a large height adjustment margin, but it is also possible to use one that is screwed into only one of the connecting portion 3 and the cylindrical portion 5A.

The edge portion of the floor member 7 inserted between the support member a and the horizontal plate portion 1 is provided with a notch 7a on the upper surface so that the head of the fastener 4 does not protrude upward, as shown in FIG. There is.

When another floor member 8 is superimposed on the upper surface of the floor member 7 as shown in FIG. 6, and when the cutout 8a is formed on the lower surface of the upper floor member 8, There is no need for the notch.

The supporting member a, the horizontal plate part 1, and the vertical plate part 2 are generally made of plastic or cast iron, and their dimensions are approximately 150 x 150 mm for the 4-sided type and 8 mm for the 2-sided type.
It is approximately 0x150mm2.

As the vibration isolating material C, an aggregate of glass fibers is compressed and shaped to a high density of about 150 to 800 kg/m3,
Those whose entire surface is covered with a rubber film are particularly excellent in terms of vibration isolation.

In FIG. 5, the connecting portion 3 is separate from the support member a and is detachably inserted into the horizontal plate portion 1, but it goes without saying that the connecting portion 3 may be integrated with the support member a.

Further, although the connecting portion 3 in FIG. 5 is in an upwardly protruding state with respect to the support member a, it may be constructed in a downwardly protruding state as shown in FIG. 7.
