DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support leg unit panel used for constructing a double floor structure or as a floor panel, and more particularly to a support leg unit used by being connected and installed on a base floor. About the panel.

[0002]

2. Description of the Related Art A double-floor structure is widely used to perform electrical wiring in a building inside a floor. In such a double floor structure, the upper floor member is supported on the lower floor portion, and electrical wiring and the like are performed by utilizing the space between the two. As a configuration for supporting the upper floor member, various types such as a support means having a wiring groove and a means having a plurality of support legs and performing wiring between the support legs are used. I have.

[0003] In such a double floor structure, there are demands for weight reduction, flame retardance or non-flammability, high strength, low cost, and ease of construction of the members used therein. In order to respond, a support means having a plurality of support legs is formed by using a flame-retardant or non-combustible resin material.

In the case of such a structure using a support leg unit panel having a plurality of support legs, since the support leg unit panel is widely installed on the floor, the stability of the installation state of the support leg unit panel is reduced. In order to achieve this, it is necessary to connect the support leg units.

For example, in the floor wiring structure disclosed in Japanese Patent Application Laid-Open No. 4-124366, a plurality of circular support legs having different sizes are arranged, connected by beams, and the wiring panel thus formed is not fixed. In this state, it is laid on the lower floor, and the lid panel is installed from above. The lid panel is formed with a hole into which the upper end of the circular support leg engages.

[0006] Also, the published patent publication sho 63-50212
Japanese Patent Publication No. 5 discloses a technology of a decorative floor support unit as a flooring of the invention. According to this technique, a plurality of posts corresponding to supporting legs are joined to each other by a substantially rectangular frame structure, and a joining means with another unit is formed outside the frame (FIG. 3), or a plurality of posts are provided. A unit for connection other than the unit in which the frame is joined by a frame, and the connection unit is used to connect with another toilet floor support unit (FIG. 8). (FIG. 5, FIG. 6) formed by extending connecting means for connection from one post of a unit joined by the above.

Further, Japanese Patent Application Laid-Open No. 6-322947 discloses a support leg unit having a double floor and a technology of a double floor structure. FIGS. 14 and 15 show a support leg unit disclosed herein. 2 shows a plan view and a side sectional view of FIG.

As shown in the drawing, the support leg unit has a plurality of support legs 51, and the plurality of support legs are connected to each other by a rib 52 as a first connecting member. Then, a rib 53 as a second connecting member protrudes outward from the connected support leg group, and a connecting ring 5 through which the support leg 11 can be inserted is provided at the distal end thereof.
4 are provided. With such a configuration, the ring 5
By installing the support leg units 4 while passing them through the support legs 51 of the adjacent units, a plurality of support leg units can be continuously connected and installed.

[0009]

However, in the case of the technique disclosed in Japanese Patent Application Laid-Open No. 4-124366, there is no means for connecting the panels to be installed at the stage of the installation. Thus, the double floor structure is completed, but there is a situation in which the wiring panel is displaced during or after the installation of the panel, and the positioning operation becomes complicated.

[0010] In addition, the published patent publication sho 63-50212
In the case of the technique disclosed in Japanese Patent Application Laid-Open No. 5 (1993) -1995, for example, units connected by a substantially rectangular frame are connected by engaging a concave portion and a convex portion provided on an outer portion of the frame by horizontal movement (FIG. It is extremely difficult to attach and detach only a unit at a predetermined location after connecting a plurality of units, and it is difficult to cope with the necessity of removing some units during work.

In the case where a connecting unit different from the supporting leg unit is provided as described above, the number of members is increased and the manufacturing process is complicated, and the unit is installed on the lower floor. The work also involves installing two types of members, and the workability is reduced.

Next, the case where the support leg unit and the connecting unit are integrally formed so as to be continuous at one support leg (F)
IG5, 6), when a plurality of units are successively installed with a two-dimensional spread, difficulty in connection arises, and the difficulty in installation near the wall of the floor increases.

Further, in the case of the supporting leg unit disclosed in Japanese Patent Application Laid-Open No. 6-322947, the units are connected to each other by passing a connecting ring through the supporting legs existing at the edge of the supporting leg unit. In this case, the configuration is the same as the configuration in which only the support legs for supporting the upper floor member are continuously arranged. However, in this connection operation, the work of passing the connection ring 54 must be performed from a position higher than the support leg 51, so that the lifting operation of the ring 54 is supported when the unit is installed or when the unit is removed after installation. Since it is necessary to reach the high position of the leg 51, the work becomes difficult.

Further, as can be understood from FIG. 15, since the operation of putting the ring 54 on the support leg 51 is performed, the rib 5
Since the rib 53 is located above the two, a step occurs between the two ribs. Therefore, in the wiring in the double floor space, the cable etc. will hit the wave at the step part,
This is an unfavorable state as a wiring situation.

[0015] Further, even in a floor panel having a leg group consisting of a plurality of legs (not for a double floor), problems such as difficulty in connection / disconnection work between the leg groups and instability of the connection state. , As well as the double floor panel.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object a simple structure which enables easy connection and installation while reducing the weight and cost of a panel and which is easy to remove after installation. A supporting leg unit panel.

[0017]

A supporting leg unit panel according to the present invention comprises a plurality of legs connected by connecting portions to form a group of legs, and a plurality of connecting members outside the group of legs. A connecting arm portion including an arm is provided. The connecting arm portions are set such that a predetermined number of the distal ends of the respective arm portions are located on each of the substantially square sides surrounding the leg group. In addition, one of the tip portions located on two adjacent sides is provided with a connecting leg portion having substantially the same height as the leg portion and having a concave portion formed in the bottom portion. Further, the tip located on the other two sides is provided with a small connecting projection having a height lower than the height of the leg and engaged in the recess.

With such a unit configuration, the support leg unit panels can be easily connected to each other by engaging the small connection protrusions in the recesses on the bottom surface of the respective connection leg portions. (Claims 1 and 2).

Further, according to the present invention, the legs of the leg group are constituted by a main leg having a large supporting area and an auxiliary leg having a smaller supporting area than the main leg, and the auxiliary leg is provided between the main legs. The upper floor member can be supported at an intermediate position. Therefore, the stabilization of the support of the upper floor member is achieved while minimizing the decrease in the internal space of the double floor. The configuration of the legs in the leg group is configured such that the main leg is disposed at the outermost edge, and the connection of the distal end of the connecting arm extending outward from the leg group. The installation position of the leg with respect to the main leg is set substantially equal to that of the auxiliary leg.

Therefore, when the connecting leg of one unit is put on and engaged with the small connecting protrusion of the connecting arm of the adjacent unit, the position is substantially the same as that of the other auxiliary legs, ie, one unit This unit is located between the outermost main leg of the other unit and the outermost main leg of the other unit. It can also be secured in a part (claim 3).

Further, the height of the connecting small projection is equal to the height of the auxiliary leg portion.
By setting the height to be as low as 1/10 or less, the engaging operation of the connecting leg and the connecting small projection can be performed extremely easily, and the mounting and dismounting of the supporting leg unit is extremely easy even after installation. (Claim 4).

Further, by making the shape of the upper end of the connecting small projection into a curved shape having no corners, the operation of putting the connecting leg on the connecting projection becomes easier.

Also, the locking structure between the small connecting projection and the connecting leg is provided with a projecting portion projecting from the side of the small connecting projection, and the projecting portion is provided in the recess in the recess of the connecting leg. By adopting a configuration in which it is locked by the receiving portion, it is possible to further strengthen the engagement between the two.

[0024]

Embodiments of the present invention will be described below in detail with reference to the drawings. This embodiment shows an example in which the present invention is used for construction of a double floor structure.

As shown, the support leg unit panel 10
Are two types of legs, the main leg 14 and the main leg 14
The auxiliary leg 16 has a smaller support surface area. The main leg 14 and the auxiliary leg 16 are connected by a band-shaped connecting member 18 having a predetermined width. Thereby, the weight of the panel can be reduced.

The shape of the main leg 14 shown in FIGS. 1 and 2 has a substantially octagonal planar shape, and the main leg 14 shown in FIGS. 3 and 4 has a circular planar shape. doing. And
In the supporting leg unit panels of FIGS. 3 and 4, more connecting members 18 are provided than in the supporting leg unit panels of FIGS. 1 and 2, and the connection strength is improved.

In this embodiment, nine main legs 14 and four auxiliary legs 16 are provided, and the auxiliary legs 16 are provided between the main legs 14 on the floor provided on these legs. The upper floor member as a plate can be supported.

The support surface 14a, which is the upper end surface of the main leg 14, has a cross-shaped groove 14b. This groove 14b
Is for locking the member in this groove when installing the upper floor member as a floor plate.

In this way, a leg group is formed in a state where the main leg 14 and the auxiliary leg 16 are connected by the connecting member 18, and a connecting arm 22 is further provided in this leg group. The connecting arm 22 projects the connecting arm 22 having the same configuration as the connecting member 18 from the outermost main leg 14, and connects the connecting leg 24 or the connecting leg 24 to the tip of the connecting arm 22. The small projections 26 are formed so as to be substantially V-shaped.

This is a shape for improving the strength of the protruding connecting arm portion 22, and is effective for withstanding stress generated during construction or the like. The distal ends of the connecting arms 22 are set so as to be positioned on each of the substantially square sides (shown by broken lines 100 in the figure) surrounding the leg group. In this embodiment, the connecting leg portion 24 and the connecting small protrusion 2 are provided on two adjacent sides of the square shape.
6 are formed separately.

As can be understood from FIGS. 1 and 2 (a diagram showing the configuration of FIG. 1 as viewed from the side), the main leg 1
4 are formed at the same height, and the auxiliary leg 16 is formed at a height slightly lower than the height of the main leg 14. That is, the auxiliary leg portion 16 positioned substantially at the center of the upper floor member as a floor plate, which will be described later, bridged between the main leg portions 14 serves as an auxiliary when a load is applied to the center position of the upper floor member. It is configured to support this.

The shape and height of the connecting leg 24 are substantially the same as those of the auxiliary leg 16. Also,
The distance from the main leg 14 is set in substantially the same manner. The connecting small projection 26 is formed by the main leg 14 and the auxiliary leg 1.
6, which is very low compared to the height of 6, which is approximately 3 in this embodiment.
The height is set to be less than one-half, and the upper end is formed in a curved shape with a corner dropped.

FIG. 5 is a schematic plan view showing a state where the support leg unit panel 10 according to the embodiment of FIG. 1 is connected.

As shown in the figure, the two supporting leg unit panels 10-1 and 10-2 are in a connected state in which the two connecting small projections 26 are engaged with the connecting leg portions 24. As described above, since the connecting portions that can be connected and engaged with each other are formed by using the two sides of the above-described substantially rectangular shape, when a large number of support leg unit panels 10 are continuously installed with a planar spread, they are sequentially and easily made. This can be performed without considering a complicated arrangement.

As shown in the figure, the floor plate 30 as the upper floor member is installed so as to be supported by the four main legs 14. The floor plate 30 is made of, for example, metal, and has bent portions bent downward at four corners in order to improve load-bearing strength. The bent portions are grooves 1 on the support surface of the main leg portion 14.
4b.

As shown in the drawing, in a state where the two support leg unit panels 10-1 and 10-2 are connected, the connecting portion between the two is that the main leg 14 and the connecting leg 24 are not the connecting portion. The positional relationship between the portion 14 and the auxiliary leg portion 16 and the supporting relationship of the upper floor member can be maintained, and the connecting structure portion is exposed and inconspicuous, and irregularly changes the wiring space of the double floor structure. It is understood that the concatenation is performed without any connection.

The connecting operation of the supporting leg unit panels 10 is basically performed by first setting one supporting leg unit panel 10-1 on a floor as a base as shown in FIG. An operation of installing the adjacent support leg unit panel 10-2 is performed.
1 support leg unit panel 1
This is performed by installing the corresponding connecting leg portions 0-2 so as to cover them from the bottom surface side.

1 to 6, for example, the main leg 14
And the auxiliary leg portion 16 and the connecting leg portion 24 are arranged in reverse positions, and the main leg portion 14 and the connecting small protrusion 26
It is also possible to connect with.

FIG. 7 is a schematic enlarged view of a connecting portion of each support leg unit panel.

As shown, the support leg unit panel 10
At least the connecting member 18 is made of, for example, an integrally molded resin and is formed to have flexibility by making it thinner, and the connecting arm portion 22 can be easily bent upward. Therefore, an operation of placing the connecting leg portion 24 on the connecting small projection 26 of the unit 10-1 while shifting the position while the adjacent supporting leg unit panel 10-2 is once set on the floor surface can be performed. . That is,
Position lower than the height of the leg (height position of the small projection for connection)
It is sufficient to perform the covering operation, so that it is not necessary to perform the operation of lifting and connecting the entire support leg unit panel 10, and the connecting operation is an extremely easy operation.

In the above-described embodiment, an example is shown in which the legs are constituted by the main leg 14 having a large supporting area and the auxiliary legs 16 having a small supporting area. However, the present invention is not limited to such a leg constitution. It is also possible for the leg group to be composed only of the main leg 32 having a common support surface, and FIG. 8 shows an example of the configuration of the connecting portion when the leg group is composed only of such a main leg 32. Is shown.

As shown in the drawing, the connecting small projection 36 is set at a height that is less than half the height of the main leg 32, and the connecting leg 34 has a common height with the main leg 32. It has an outer shape, and a rib 35 is provided inside to enhance the strength. In the connecting operation, as in the case of FIG. 7, the connecting small projection 36 is engaged and installed so as to cover the connecting leg 34.

FIGS. 9 to 11 show other examples of the structure of the connecting leg and the connecting small projection of the connecting arm.

First, in the example shown in FIG. 9, the configuration of the connecting small projection is changed, and the configuration of the connecting leg 24 is the same as that of FIG. That is, the connecting small projection 40 is separated into two substantially at the center, and the two separated parts slightly separated from each other are connected to the hollow connecting leg 2 having an open bottom.
When the cover 4 is put on from above, it is pressed in a direction approaching each other to perform an engagement operation. As a result, the two separated portions of the connecting small projection 40 urge the connecting leg 24 in a direction of expanding outward, so that the connecting engagement state between the two is further strengthened.

FIG. 10 shows the structure of still another connecting portion. In the present embodiment, the connecting small projection 42 is composed of two pieces 42a and 42b, and the two pieces 42a and 42b are configured to be able to bend in the approaching direction by applying a predetermined force to each other. . And
On the outer surface of each piece, a protruding portion 4 with an enlarged diameter
3 are formed.

On the other hand, the connecting leg 24 has
Holes 25 are formed in the side wall as engagement portions with which the projections 3 are engaged, respectively, at positions opposed to the protrusions 43. Therefore, by covering the connecting leg 24 from above the connecting small projection 42, the two pieces 42a of the connecting small projection 42,
42b are bent in a direction approaching each other, and fit in a state where the projection 43 of the small connecting projection 42 is engaged with the hole 25 at the end of the covering operation. In this manner, a stronger connection state is ensured than in the engagement state in which the connection leg is merely covered with the small connection protrusion as shown in FIGS.

As shown in FIG. 11, the shape of the small connecting projection is such that the shape of the projection 43 is such that the upper side is an inclined surface and the lower side is a vertical surface. The connection engagement state can be prevented from being released unless the operation of pushing the projecting portion 43 inward from the outside of the hole 25 of the user leg portion 24 is performed.

The connecting small projection 42 has not only a configuration in which it is divided into two pieces as shown in FIG. 12 as viewed from above, but also a configuration in which it is divided into four pieces 42a to 42d. It is also possible. In this case, the holes 25 of the connecting leg 24 are formed at four corresponding locations.

FIG. 13 shows an example in which a support floor unit panel according to one embodiment is installed on an actual floor to construct a double floor structure, and FIG. 13 shows an installation state near a wall of the floor. Have been.

As shown in the figure, a plurality of support leg unit panels 10 according to the present invention are sequentially connected and installed to a predetermined position near a wall. Here, a border panel 50 whose width can be adjusted by cutting off is installed near the wall. A border cover 52 is provided on the border panel 50 closest to the wall, and a border sheet 54 is provided in other areas of the border panel 50.

On the other hand, the end of the support leg unit panel 10 is installed so that the connecting leg 24 is located.
The position of the border panel 50 is adjusted so as to reach a predetermined position from the connecting leg 24. Accordingly, by installing the floor plate 30 as the upper floor member in this portion, the floor plate 30 is connected to the border panel 50 and a part of the outermost main leg portion 14 and the connecting leg portion located therebetween. 24. The supporting structure in which the connecting leg 24 supports the floor plate 30 at substantially the center position is the same as the other structure of the supporting leg panel, and the floor plate 30 at the end of the installation of the supporting leg unit panel 10. Therefore, the stability of the installation state is also ensured.

As described above, the floor plate 30 is installed in such a manner that the four corners thereof are also supported by the main leg portion 14 in the connection region of the support leg unit panel 10 and the auxiliary leg portion 16 or the connection The leg 24 is located in a supportable state. That is, this supportable state means that the height of the auxiliary leg 16 and the connecting leg 24 is slightly lower than the height of the main leg 14, and, for example, the device is located at the center of the floor plate 30. When a load due to installation or a load due to human walking is applied, the floor plate 30 bent by the load is supported.

Thus, it is possible to reduce the thickness of the steel plate of the floor plate 30 as much as possible while maintaining the load resistance, and it is also possible to reduce the weight and cost. For example, it is possible to use 1.6 t rather than 2.3 t of the plate thickness, and it is possible to greatly reduce the cost.

It should be noted that the present invention is not limited to the configuration of each of the above embodiments, and various modifications are possible within the scope of the invention. For example, the number and the shape of the support legs constituting the leg group are not limited to the above-described configuration, and various numbers and shapes can be set.

The internal structure of each of the legs can be a solid structure, and all the legs have a hollow structure with ribs inside to strengthen the strength and reduce the weight. It is.

[0057]

As described above, according to the present invention, it is possible to construct a supporting leg unit panel panel having a simple structure and extremely easy to connect. In addition, stabilization of the connection state can be ensured and attachment / detachment is easy, and attachment / detachment by a simple operation is possible even once installed on the floor. Further, since the connecting member does not protrude between the legs supporting the upper floor member, the connecting connection portion does not stand out. Further, when used as a double floor, a wiring space between the legs can be effectively secured.
