Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a fixing device for floor panels on double floors such as OA raised floors.

(Prior art) OA raised floors are usually constructed with double floors, but in many cases, the four corners of the floor panels are supported by supporting metal fittings erected on the base concrete floor. It is composed of.

In this case, in order to easily change the wiring under the floor due to changes in the layout of the office, the floor panels were made into small pieces with a side of about 500 mm, and the installation method was also made as simple as possible. The top of the supporting hardware has grooves and projections, and the floor panel is processed to correspond to the grooves and projections, and the floor panel is often set through the grooves and projections. These grooves and protrusions are dimensioned with clearance in mind, due to workability issues when installing floor panels.

(Problem to be solved by the invention) Therefore, in the conventional double floor structure, the floor panels are divided into small pieces, and the mode of vibration varies depending on each floor panel due to differences in load conditions. , and can be considerably larger than the vibration of the base concrete floor.

Therefore, such vibration of the floor panel carries the risk of causing computers, OA equipment, etc. placed on the panel to fall over.

(Means for Solving the Problems) The present invention was proposed to solve the above problems, and it consists of four floor panels that are erected from the base concrete floor and meet at one point. a truncated four-sided pyramid fitted to a floor panel support bolt facing into the space formed between the corners; a truncated four-sided pyramid interposed between the side end surface of each floor panel and the outer peripheral surface of the truncated four-sided pyramid; This invention relates to a double floor panel fixing device characterized by comprising a wedge member slidable along the outer circumferential surface of the double floor panel, and a cap set on the head of the truncated four-sided pyramid.

(Function) and (Effects of the invention) As mentioned above, in the present invention, the floor panel is raised from the basic concrete floor and faces into the space formed between each corner of four floor panels that meet at one point. A truncated four-sided pyramid is fitted onto the panel support bolt, and a wedge member is provided between each inclined outer circumferential surface of the four-sided truncated pyramid and the side end surface of each of the floor panels, and a wedge member is provided on the outer circumferential surface of the four-sided truncated pyramid. Since each of the floor panels is interposed so as to be slidable along the wedge member, horizontal force is transmitted to each other through the truncated four-sided pyramid fitted to the wedge member and the floor panel support bolt, and the floor panels is firmly fixed in the horizontal direction.

As described above, according to the present invention, since the adjacent floor panels are integrated through the support bolts, the truncated four-sided pyramid, and the wedge member, in the event of an earthquake,
Vibrations caused by construction errors in floor panels and clearances for absorbing product errors are eliminated, and vibrations and floor noises caused by normal human traffic and work can be eliminated.

Further, a wedge member interposed between the outer circumferential surface of the four-sided truncated pyramid and the side end surface of the floor panel is slidably mounted along the outer circumferential surface of the four-sided truncated pyramid, and Since it is wedged, it can fully cope with construction errors when installing floor panels and positional deviations due to product errors.

Furthermore, in the present invention, since a cap is set on the head of the truncated four-sided pyramid, the space formed between each of the floor panels is closed by the cap, making it difficult to install the floor finishing material. This will be done without any problems.

(Example) Hereinafter, illustrated embodiments of the present invention will be described.

In FIGS. 1 to 3, A is a truncated four-sided pyramid, and a concave cavity 1 is provided at the center of the lower base, and vertical grooves 2 are bored in each outer circumferential surface.

Reference numeral B designates a wedge member whose outer peripheral surface is formed as a vertical surface, and whose inner slanted surface is provided with protruding ridges 3 that slidably engage with the longitudinal grooves 2.

C is a cap, and a frame portion 4 provided in the lower half of the cap has a protrusion 5 projecting thereon which fits into the vertical groove 2 of the truncated four-sided pyramid A.

D is a base concrete floor, and the floor panel F is attached to the convex portion 8a of the support plate 8 supported via nuts 7 to the floor panel support bolts E set up on the base plate 6 disposed on the same floor D. Lower bottom recess 9
are fitted, and thus the floor panel F is supported by the support bolts E.

Then, the concave hole 1 of the truncated four-sided pyramid A is screwed into the floor panel support bolt E that protrudes into the space formed between the corners of the four floor panels F that meet at one point, and The protrusions 3 of the wedge member B are fitted into the longitudinal grooves 2 on the outer peripheral surface of the truncated four-sided pyramid A, and the wedge members B are slid into the wedges until they are pressed against the side end surfaces of the floor panel F, and then the cap C is fitted onto the head of the truncated four-sided pyramid A to close the space formed between each of the floor panels F, and the floor panel F
Complete the installation. In the figure, 10 is a floor finishing material placed on the floor panel F and the cap C.

Since the illustrated embodiment is configured as described above, the adjacent floor panels F are firmly fixed in the horizontal direction via the truncated four-sided pyramid A and the wedge member B, so that in the event of an earthquake, Floor panel F has construction error.
Also, vibrations caused by clearances for absorbing product errors are eliminated, and vibrations and floor noise that normally occur due to human walking and work are eliminated.

Furthermore, the floor panel F is fixed by wedge members B being wedged independently into each outer peripheral surface of the truncated four-sided pyramid A and the side end surface of each floor panel F, so that the floor panel F is fixed. It is possible to sufficiently deal with construction errors when installing Panel F and positional deviations due to product errors.

Furthermore, by setting the cap C on the head of the truncated four-sided pyramid A, the space formed between each of the floor panels F is sealed, and the floor finishing material can be easily applied. Chamfered portions 11 are provided at the four corners of the panel F to reduce the occurrence of defects and cracks in these portions during transportation work. (See Figure 4)
