Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to floor panels for construction, particularly supports for floor panels in OA floors and floors incorporating air conditioners.

(Conventional technology) Traditionally, wooden joist floor panels have often been used for general construction, but in recent years intelligent buildings for the purpose of storing wiring, piping, etc. are often using double-floor panels. It is used. Joists have the disadvantage that when wiring or piping is carried out, the horizontal horizontal members become an obstacle and construction is difficult.

In addition, after construction, the joists and facing materials of a floor structure made of wood contain moisture and will slowly shrink in volume after 1 to 2 years due to natural drying. This will cause gaps and squeaks due to deformation or loosening. Wiring like a house,
Although it can be used when the amount of piping is small, in the future when home automation increases, the joist method will not be able to handle it, and it is thought that the independent column type will be used.

Although independent supports are used in computer rooms and OA floors, metal supports are mainly used. This is because metal supports are lightweight, mass production methods have been established, and they are economically advantageous.

(Problem to be solved by the invention) However, in the case of metal columns, when the floor height exceeds 200 mm, the amount of deformation in response to horizontal force increases, and the floor height increases.
When it reaches 450mm, it is necessary to install horizontal plates and rooting.

Furthermore, bonding the concrete frame and the metal support with an adhesive involves bonding dissimilar materials, which may lead to the problem of peeling over the long term. At the adhesive interface of the pillar, repeated vertical movements due to walking, long-term compressive force and creep from equipment act, and the
Interfacial delamination often occurs in 10 to 30% of cases.

As for adhesives, two-component epoxy resins are strong against static horizontal forces, but are particularly weak against impact forces, and easily fall over with just a light tap with a hammer.

Also, although vinyl acetate adhesives have good workability,
It reacts with the alkali in the concrete of the floor slab and deteriorates over a long period of time, reducing adhesive strength.

Furthermore, although urethane-based adhesives are better than vinyl acetate-based adhesives, they have the problem of large flow and easy slippage.

(Means for Solving the Problems) The present invention was proposed in order to solve the above problems, and includes a hollow cylindrical concrete support installed above the floor and a screw threaded into the support to be able to rise and fall freely. a vertically adjustable true column with a horizontal plate fixed to its upper end face; a vertically adjustable true column that is screwed into the horizontal plate so that it can be raised and lowered; the upper end is configured to fit into a vertical through hole of a floor panel; A floor panel comprising: a screw rod for fine adjustment of height, to which a floor panel support seat piece is fixed; and a compression bomb interposed between the floor panel support piece and a horizontal panel. This is related to the support pillar.

(Function) Since the present invention is configured as described above,
By erecting a hollow cylindrical concrete column on the floor and screwing a vertically adjustable vertical column around the column, the height position of the horizontal plate fixed to the upper end surface of the vertical plate can be adjusted. Adjust the screw rod for height fine adjustment screwed into the horizontal plate so that it can be raised and lowered freely.
The upper end of the screw rod fitted into the vertical through-hole of the floor panel can be twisted by operating it from above the floor panel to finely adjust the height position of the floor panel support seat piece fixed to the upper part of the trunk of the screw rod. The floor panel is then set at a predetermined height above the floor.

The seat piece is constantly pushed up by the urging force of a compression bullet interposed between the floor panel supporting seat piece and the horizontal plate, thereby eliminating rattling. This also prevents the floor panel from loosening due to repeated loads caused by walking or the like.

When the floor height becomes high, an upper concrete support is connected to the concrete support using, for example, a thick pin and an adhesive.

(Effects of the Invention) In this way, in the present invention, the main body of the support of the floor panel is constituted by a hollow cylindrical concrete support, and the support is erected on the floor of a concrete frame made of the same material as the support. This makes it possible to construct floor panel supports that are structurally more stable and economically advantageous than metal or wooden supports.

In addition, a height-adjusting pillar is screwed into the concrete pillar so that it can be raised and lowered, and a seat piece for supporting the floor panel is screwed into a horizontal plate that is fixed to the upper end surface of the pillar, and a seat piece for supporting the floor panel is installed on the upper part of the trunk. The floor panel can be accurately installed at a predetermined height from the floor by using the height fine adjustment screw to which the floor panel is fixed.

Moreover, the compression bullets interposed between the floor panel supporting seat piece and the horizontal plate can prevent the floor panel support from shaking.

Furthermore, since the pillars are made of concrete, the pillars can be easily raised to raise the floor height.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Reference numeral 1 denotes a hollow cylindrical concrete support column, and a steel plate 2 for attachment to the floor A surface is integrally joined to the lower end of the column via a barb 3 protruding from the steel plate 2.
Further, an embedded nut 4 is fixed to the top of the column 1, and is integrally attached to the floor A surface via an iron plate 2, an anchor bolt 5, an adhesive, etc. for attaching the column 1.

A height adjusting straight post 6 having a spiral rod shape is screwed into the embedded nut 4 so as to be movable up and down, and a horizontal plate 7 is welded to the upper end of the straight post 6. Further, a rotation preventing nut 8 is screwed onto the true pillar 6, and a nut tightening rod 9 is provided protruding from the nut 8 by welding.

This is because tightening the nuts 8 one by one with a tool to prevent the rotation of the true pillar 6 takes too much man-hours, and because the work is done in a narrow space, the tightening tends to vary. By protruding the rod 9 from the anti-rotation nut 8, the nut 8 can be easily tightened by hand.

The shorter the tightening rod 9 is, the better, but it is necessary to prevent the moment when tightening the nut 8 from becoming too small. Further, it is preferable to provide a bent portion 9a at the tip so that a communication cable or the like does not get caught. Furthermore, a pipe having a larger diameter than the tightening rod 9 may be fitted onto the rod 9 to make it longer.

Nuts 10 are welded to the lower surface of the horizontal plate 7 at a plurality of locations, and a screw rod 11 for fine height adjustment is passed through the horizontal plate 7 at each nut installation location, and the lower end thereof is attached to each nut 10 so that the height can be adjusted freely. A horizontal floor panel seat piece 12 is welded to the trunk portion of each screw rod 11, and a compression ammunition 1 is attached between the seat piece 12 and the horizontal plate 7.
3 is interposed. The upper end of the screw rod 11 is fitted into a through hole b of the floor panel B supported by the seat piece 12, and a hexagonal cylindrical recess 11a is provided on the upper end surface. The screw rod 11 is rotated by a hexagonal wrench C engaged with the recess 11a from above the floor panel B.

Since the illustrated embodiment is configured as described above, the concrete support 1 erected on the floor A
Adjust the height of the true pillar 6 by screwing it, position the horizontal plate 7 at the upper end of the true pillar 6 at a predetermined height, and operate the tightening rod 9 to tighten the nut 8.
is tightened to fix the true pillar 6 at a predetermined height.

Next, the floor panel seat pieces 1 of each of the screw rods 11
2 supports the floor panel B, and finely adjusts the height of the floor panel by screwing each of the screw rods 11.

In this way, according to the embodiment, the floor panel B is accurately installed at a predetermined height from the floor A by adjusting the height adjustment straight pillar 6 and the height fine adjustment screw 11 in a spiral manner. be able to.

In addition, the true pillar 6, the spiral rod 11 and the nuts 4, 10
There is a looseness of about 0.1 to 0.3 mm in the threaded portion between the floor panel B and the floor panel B, which loosens little by little when walking on the floor panel B, increasing the looseness.

However, in the embodiment described above, the compression bullet 13 interposed between the floor panel seat piece 12 and the horizontal plate 7 constantly pushes up the seat piece 12, causing the rattling. This also prevents loosening due to repeated loads.

Furthermore, in order to completely prevent loosening, the bullet 13
It is preferable to lock the end portion of the seat piece 12 into a locking hole provided in the horizontal plate.

In addition, in the above embodiment, since the pillar 2 is made of concrete, it is structurally and economically advantageous compared to wooden or metal pillars, and the floor height can be increased, such as when an air conditioner is installed under the floor. In this case, the upper support 1' is layered on top of the support 1 via the thick-handled pin 14, and the upper support 1' is jointed onto the support 1 by bonding the two with adhesive 15. . (See Figures 4 and 5) Furthermore, by coating the concrete support 1 with acrylic urethane added with an antistatic agent, dust generation can be suppressed, and the concrete pillar 1 can also be applied to clean rooms. In addition, the support column 1 has less floor vibration than a metal support column, and since the support column is made of concrete, its rigidity is increased, which improves its performance against horizontal forces.
