[0014]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic structure of a double floor, in which a hollow floor panel 1 is laid on an existing floor A via support legs 2. Among the hollow floor panels 1, the hollow border panel 1 located in the peripheral portion near the standing object B, such as a wall, equipment, or a library, has a part of the border panel 1 conforming to the shape of the standing object B. Will be cut like this.

Hollow border panel 1 used in the present invention
Is composed of a front plate 3 and a back plate 4 as shown in FIGS. 2, 3, and 4. The front plate 3 is made of a steel plate, and a sheet metal material is punched into a substantially square shape. It is formed by punching out a cylindrical projection 5 projecting to the side. Back plate 4
Is formed by punching a sheet metal material also made of a steel plate, and provided at a position corresponding to the protruding portion 5 of the front plate 3, a rising portion 6 bulging in a hemispherical shape, and a top of the rising portion 6. A hole 7 into which the protrusion 5 is fitted is formed in the hole, and the protrusion 5 is inserted through the hole 7 so that the top of the upright portion 6 and the top plate 3
And are connected. Further, the peripheral portion 8 of the front plate 3 is bent and wound around the lower surface of the flange portion 9 on the peripheral portion of the back plate 4 to be crimped and joined.

Accordingly, the front plate 3 and the back plate 4 are connected to each other by the projections 5 and the tops of the upright portions 6 and the peripheral portions 8, 9, and a hollow portion 10 is formed therebetween. The hollow portion 10 is formed by a peripheral edge space 11 and a space 12 between the upright portions.

In the peripheral portion, the hollow border panel is appropriately cut in accordance with the shape of a wall, a column, or a standing object B such as equipment or a library. For example, when cut linearly as shown by the line AA in FIG. 4, when cut into irregularities like the line BB, or when cut along a curve like the line CC, etc. Various cutting forms are conceivable.

As a result of this cutting, even if the unit floor panel has passed a predetermined load test or an impact test, the unit floor panel that has obtained the predetermined strength by the upright portion 6 bulging in a dimple shape can be obtained. A predetermined strength cannot be obtained by cutting the upright portion 6. However, it is difficult to cut while always avoiding the upright portion 6. Therefore, it is important to provide some kind of reinforcement in order to prevent a decrease in strength caused by cutting the upright portion.

FIG. 5 shows an embodiment corresponding to a straight cut of a hollow border panel. Reference numeral 13 denotes a U-shaped long metal member provided along a substantially straight standing member B such as a wall surface, and is constituted by an upper flange 14, a lower flange 15, and a web 16. The U-shaped long metal member 13 is placed and fixed on the support leg 2 disposed at the periphery of the chamber with the web 16 closely or closely to the standing object B such as a wall surface. Therefore, the opening 17 is exposed on the indoor side.

As shown in FIG. 6, the cut side of the hollow border panel is inserted into the opening 17 to fix the hollow border panel. In the embodiment, the upper flange 1
4 has a length of about 30 mm, and a U-shaped long metal piece has a thickness of 1.2 mm. Regardless of the state in which the upright portion 6 is cut, the strength of the upright portion 6 due to cutting is reduced. Covering with 14 enables reinforcement.

The lower flange 15 is formed longer in the short direction than the upper flange 14, and an extension of the lower flange 15 is formed with a mounting hole 18 to the support leg 2.
U-shaped long metal hardware 1 with 4 tapping screws 19 etc.
3 can be fixed to the support leg 2. Mounting hole 18
Are formed in consideration of the arrangement of the upright portions 6 and the like, so that the screw heads are located in the gaps 11 and 12 on the panel back surface 4 and do not hinder the arrangement of the hollow border panel. . Further, a flat surface screw can secure a smooth surface inside the lower flange 15.

FIG. 7 is a side view showing a state in which the surface material 20 to be finished is installed, and shows a state in which the double floor structure is in contact with an upright B such as a wall, equipment, or a library. The web 16 of the U-shaped long metal piece 13 of the present invention is brought into contact with the standing object B, and the hollow border panel 1 is inserted and arranged in the opening 17 of the space surrounded by the web 16 and the upper and lower flanges 14 and 15. Has been established. Since some clearance can be provided between the web 16 and the hollow border panel 1, it is extremely effective in the construction process. In this embodiment, a U-shaped long metal piece 1 is used.
An elastic body 21 such as a rubber cushion is disposed between the third member 3 and the standing object B to absorb vibration, absorb expansion and contraction of members, and the like. A carpet or the like is laid as a surface material 20 on the hollow border panel. Since the thickness of the upper flange 14 is about 1.2 mm, the thickness is absorbed by the elasticity of the carpet, and a step is formed on the surface. There is nothing.

FIG. 8 shows a set of the cut-out material 22 and the hollow border panel 1, the U-shaped long metal member 13, the elastic body 21, and the cut-out material 22 facing the standing object B in the same manner as described above.
It is arranged.

FIGS. 9 to 13 show another embodiment of the peripheral portion, showing a reinforcing means when the hollow border panel 1 is cut along the line BB or the line CC in FIG. FIG.
FIG. 3 is a perspective view when cut along the line BB. In the cut portion, a gap 11 at the peripheral edge and a gap 12 between the upright portions 6 are exposed. Since the diameter of the dimple-shaped upright portion 6 is constant, the interval between the gaps 12 formed between the upright portions 6 and the interval between the gaps 11 formed between the upright portion 6 and the peripheral portion become constant, and the same shape It becomes possible to insert the character-shaped reinforcing member 23.

The U-shaped reinforcing members 23 and 23 'are shown in FIG.
1, as shown in FIG. 12, formed by webs 24, 24 'and left and right flanges 25, 26, 25', 26 ',
The lengths of the left and right flanges are formed longer in consideration of the radius of the upright portion.

Further, the height of the flange is formed slightly higher than the inner dimension between the front panel 3 and the rear panel 4 of the floor panel, so that the U-shaped reinforcing members 23, 23 'are inserted between the gaps 11, 12. After that, it does not fall out of the floor panel, and the front plate 3 is slightly raised and supported. Therefore, even if the upright portion is cut off in any state by cutting the hollow border panel, a decrease in strength caused by the lack of the upright portion can be covered, and a sufficient reinforcing effect against the load applied to the panel can be obtained. The U-shaped reinforcing members 23 and 23 'can be easily inserted into the gaps 11 and 12 with a mallet or the like. Notches 27, 2 are provided at the lower end portions of the left and right flanges.
7 'can be formed. The shapes of the cutouts 27 and 27 ′ are triangular, crescent, or the like. The various tapered notches 27, 27 'facilitate insertion of the U-shaped reinforcing members 23, 23' into the gaps of the panel.

FIG. 13 is a view showing a state in which a hollow border panel having a curved cut surface along the line CC of FIG. 4 is abutted against an upright B having a curved shape. Even when the hollow border panel is cut into a curved shape, the reinforcement of the hollow border panel can be achieved by driving the U-shaped reinforcing members 23 and 23 'into the gaps of the hollow border panel.

Depending on the degree of the gap between the hollow border panel and the standing object in the peripheral portion, two floor panels located in the peripheral portion of the room may be cut in the peripheral direction from the center of the room. In this case, if the cut portions of the hollow border panel are laid together as shown in FIG. 14, the fit is good. In this case, U-shaped reinforcing members 23 and 23 'are inserted into the cut surfaces of the hollow border panel to reinforce the hollow border panels.
By adding the support leg 2 to this mating line, the cutting portion is further strengthened.

When a panel is laid in a room according to the present embodiment, as shown in FIG. 15, when a standing object B around the room is in a straight line state, the U-shaped long metal member 13 is used to cope with the column. In the case of the standing object B having an uneven portion such as a wall, the hollow border panel can be reinforced by employing the U-shaped reinforcing members 23 and 23 '. The hatched portions of the panel in the drawing correspond to the U-shaped long metal members 13, and the dotted lines correspond to the U-shaped reinforcing members 23 and 23 '.

[0030]

According to the present invention, as described in detail above, the reinforcing structure of the hollow border panel located at the peripheral portion of the double floor can easily reduce the floor panel strength caused by cutting the hollow border panel. It became possible to reinforce. The U-shaped reinforcing member also makes it possible to prevent the cut portion from being dented by a load.

The method for laying a hollow border panel according to the present invention can be performed while reinforcing the hollow border panel, and can be used for erected objects such as walls, columns, equipment, and archives. Even in the uneven state or the curved state, it is possible to cut the hollow border panel and complete the double floor conforming to the shape of the standing object while reinforcing the hollow floor panel.
