Description

  The present invention relates to a panel device for a free access floor and a lid member.

  As a panel device for a free access floor in which a lid member is detachably attached to a floor panel, a device described in Patent Document 1 is conventionally known. In this conventional example, the lid is formed of a thin plate material having a U-shaped cross section, sandwiches the facility management floor panel, and closes the notch-shaped opening formed in the side edge of the panel.

JP 2010-19024 A

  However, in the above-described conventional example, when the opening is used as a wiring outlet or the like, it is necessary to remove the lid, but in this case, it is necessary to separately prepare a storage space for the lid after removal. In addition, there is a drawback that the lid body is likely to be dissipated.

  The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a panel device for a free access floor that can store a lid member without being dissipated. Another object of the present invention is to provide a lid member used in a panel device for a free access floor.

According to the present invention, the object is
A floor panel 2 in which an opening 1 is formed in a cutout shape on a side edge;
A closing plate 4 for sandwiching the floor panel 2 in cooperation with the mounting piece 3, and a lid member 5 for closing the opening 1 by the closing plate 4;
The floor panel 2 houses the lid member 5 in a mounted state, and a lid housing recess 6 that restricts the projection of the lid member 5 from at least the upper surface and side edges of the floor panel 2;
A cover member 5 mounted on the side edge portion is removed from the closed position of the opening portion 1 and a preliminary storage recess 7 is formed that restricts the protrusion of the cover member 5 from at least the upper surface of the floor panel 2 and the side edge. This is achieved by providing a panel device for a free access floor.

  The floor panel 2 is provided with a notch-shaped opening 1 for use as a wiring outlet or the like, and a lid member 5 is prepared for the case where the opening 1 is not used as a wiring outlet or the like. The lid member 5 has a closing plate 4 having an area enough to close the opening 1 and a mounting piece 3, and the opening of the floor panel 2 is formed by the closing plate 4 and the mounting piece 3. The side edge portion on which the portion 1 is formed is sandwiched and attached.

  When the cover member 5 is mounted on the floor panel 2, the housing recess is formed with unevenness on the upper surface of the floor panel 2, that is, on the floor surface due to the cover member 5 jumping upward from the upper surface of the floor panel 2, or the cover member 5. Is to prevent the gap between adjacent floor panels 2 due to jumping out from the side edge of the floor panel 2, and the top surface and side edges of the floor panel 2 are recessed about the thickness of the lid member 5. Is formed. The preliminary accommodating recess 7 accommodates the lid member 5 which is formed on the side edge where the opening 1 of the floor panel 2 is formed or on the other side edge and is removed from the position where the opening 1 is closed. In the same manner as described above, the protrusion of the lid member 5 from the upper surface or side edge of the floor panel 2 is prevented.

  Therefore, according to the present invention, the lid member 5 that is no longer needed can be held on the same floor panel 2 by the preliminary accommodating recess 7, so that it can be prevented from being dissipated. Generation | occurrence | production of the unevenness | corrugation to the floor surface by mounting | wearing and holding | maintaining the cover member 5 can also be prevented.

  The lid member 5 described above can be mounted on the floor panel 2 in the factory in advance and carried into the construction site, thereby improving the work efficiency at the construction site. I am worried that it will fall off due to vibration. Such a drop-off can be prevented by screwing the lid member 5 to the floor panel 2 or by setting the clamping force of the lid member 5 strongly. If the latching protrusion 9 which latches to the to-be-latched part 8 made is provided in the cover member 5, the ease of removal from the floor panel 2 will not be impaired much.

  Similarly, when carrying and storing, the volume can be reduced by stacking the floor panels 2. In this case, if the lid accommodating recess 6 described above is formed so as to restrict the protrusion of the lid member 5 to be accommodated from the lower surface of the floor panel 2, the floor panel 2 can be stacked without any gap.

  Further, as described above, when the opening 1 of the floor panel 2 is used as a wiring outlet or the like, the lid member 5 is accommodated in the preliminary accommodating recess 7 and the lid accommodating recess 6 is covered with an outlet or the like so that the floor panel 2 is covered. The recesses 6 and 7 formed on the upper surface become inconspicuous. On the other hand, when the opening 1 of the floor panel 2 is not used as a wiring outlet or the like, the lid housing recess 6 becomes inconspicuous by housing the lid member 5, but the preliminary housing recess 7 remains as a recess with respect to the surface of the floor panel 2. End up. Unlike the protrusion, such a dent is inconspicuous if the size is small, and can be substantially undetectable even when walking. For example, the ridge 10 that bulges to the upper surface of the floor panel 2 in the preliminary accommodating recess 7. Can be made inconspicuous. In this case, the closure plate 4 cannot be accommodated in the preliminary accommodation recess 7 by the projection 10, but the projection 10 is received by the mounting piece 3 that forms a pair with the closure plate 4 and sandwiches the floor panel 2. Protrusion from the surface of the floor panel 2 or the side edge of the lid member 5 can be prevented by providing the through hole 11 and accommodating the mounting piece 3 in the preliminary accommodating recess 7, that is, the lid member 5 is turned upside down.

  Moreover, the lid member 5 described above can dramatically improve the load bearing performance by using a U-shaped cross section that sandwiches the floor panel 2 as compared with the conventional case. That is, in the conventional example similarly provided with a U-shaped lid, the closed portion and the floor panel abutting portion are connected to each other by a connecting portion so that the U-shaped cross-section is attached to the facility management floor panel from the upper surface side. In order to be able to do so, the closed portion is placed on the stepped surface portion formed on the periphery of the opening, whereas the connecting portion and the floor panel contact portion are wide enough to be inserted into the opening. Dimensioned. For this reason, when a vertical load is applied directly above the opening of the lid, the load concentrates on the peripheral portion of the closing portion protruding from the connecting portion in the width direction and on the stepped surface portion, and the load that causes these bending and breakage Becomes the limit of load resistance.

  Therefore, in the conventional example, the load-bearing performance is low, and there is a disadvantage that the closed portion and the floor panel become thick to compensate for this, and a material having high strength must be used for these.

  In this regard, if the lid member 5 is formed by bending a substantially square thin plate material into a U shape, a vertical load can be shared and borne by each side of the U shape. The load bearing performance can be dramatically increased, and at the same time, the load bearing performance of the floor panel 2 to which the lid member 5 is attached can be dramatically increased.

  As is apparent from the above description, according to the present invention, it is possible to provide a panel device for a free access floor that can store the lid member without being dissipated, and to smoothly change the wiring outlet and the like. be able to.

  Moreover, the load-bearing performance of the floor panel or lid member in which the notch-shaped opening is formed can be dramatically improved, and a safer floor can be provided.

  1 to 4 show an embodiment of the present invention. As shown in FIG. 4, the free access floor is formed by arranging panel receivers 21 in a matrix on the floor base 20, and each panel receiver 21 adheres an installation substrate 21 a provided at the lower end to the floor base 20. Fixed. A tray part 21b that supports the floor panel 2 is attached to the upper end of the panel receiver 21, and the four corners of each floor panel 2 that are substantially square in plan view are brought into contact with each other, and the contact corners are supported by the dish part 21b. Thus, the floor surface 22 is formed by the floor panel 2 at a predetermined height on the floor base 20. Further, a panel presser 21c is mounted on the tray 21b from above, and the abutting corner is pressed by the panel presser 21c to prevent the floor panel 2 from being displaced or lifted. A tile carpet 23 is laid on the upper surface of the floor panel 2 laid as described above.

  As shown in FIGS. 1 to 3, the floor panel 2 is formed by joining a flat plate-like upper surface plate 2a made of metal and a dish-shaped back plate 2b at the periphery, and is shown in the hollow portion 2c. Filled with omitted inorganic material. In joining the top plate 2a and the back plate 2b, the peripheral portion of the top plate 2a is folded back so as to squeeze the peripheral portion of the back plate 2b, and the top plate 2a and the back plate 2b are caulked in the center part. As a result, the floor panel 2 is formed with a flange portion 2d at the peripheral edge portion and with a dot-like caulking hole 2e at the center portion. In addition, a semicircular arc-shaped notch 2 f for drawing out the wiring is formed on the side edge of the floor panel 2. In addition, in this embodiment, although the case where the hollow part 2c is filled with the inorganic material as described above is shown, the floor panel 2 is formed by the hollow structure without being filled with the inorganic material according to the use situation of the floor panel 2. It is also possible to configure.

  The floor panel 2 includes a notch-shaped opening 1 at the center of one side edge, and the upper surface, the lower surface, and the side edge of the floor panel 2 are recessed at the periphery of the opening 1, respectively. 6 is formed. The opening 1 described above is for installing an outlet 24 or the like on the free access floor as shown in FIG. 4, and is formed to be approximately half the size of the outlet 24, and the openings 1 face each other. Thus, one set of the floor panel 2 is arranged so that the outlet 24 can be installed. Specifically, the lid housing recess 6 has a front side housing recess 6a formed by recessing the top plate 2a toward the back plate 2b, and a back surface formed by recessing the back plate 2b toward the top plate. It is comprised by the side accommodation recessed part 6b and the side edge side accommodation recessed part 6c formed by denting the above-mentioned collar part 2d in the floor panel 2 inward.

  The lid housing recess 6 has a depth similar to the thickness of a thin plate material constituting the lid member 5 to be described later, and its bottom surface functions as a flange portion that supports the peripheral edge of the lid member 5. The flange portion disposed on the upper and lower surfaces of the floor panel 2 is provided with a locking hole (locked portion 8), and the locking member 9 formed on the lid member 5 is received, whereby the lid member 5 is dropped. Functions as prevention and positioning.

  As shown in FIGS. 1 to 3, the lid member 5 described above is formed by bending a substantially square thin plate material made of metal into a U-shape, and closing the opening 1 described above, and this blocking member. The mounting piece 3 is disposed at a position opposite to the plate 4, and the connecting portion 25 connects the closing plate 4 and the mounting piece 3. The closing plate 4 and the mounting piece 3 are formed to have a size enough to fit in the front side receiving recess 6a and the back side receiving recess 6b, and the connecting portion 25 has the same width as the side edge receiving recess 6c. The length is the same as the thickness of the floor panel 2. Further, the above-described locking projection 9 is bulged on the closing plate 4 and the mounting piece 3 so as to be hemispherically pushed out from the opposite surface side at the opposing position, and this locking projection 9 is formed in the front side receiving recess 6a and the like. When the blocking plate 4 or the like is accommodated, it is disposed at a position corresponding to the above-described locking hole 8.

  Therefore, when the lid member 5 is pushed into the lid housing recess 6 of the floor panel 2 with the closing plate 4 facing the upper surface side, the hemispherical locking projection 9 first comes into contact with the flange portion, and further pushed into the lid member 5. The closing plate 4 and the mounting piece 3 are expanded by elastic deformation. When the locking projection 9 reaches the position of the locking hole 8 by continuing to push in as it is, the locking projection 9 is received in the locking hole 8, whereby the lid member 5 is elastically restored and elastically opens the lid member. 5 is housed in the lid housing recess 6. In this state, the outer surfaces of the closing plate 4, the mounting piece 3, and the connecting portion 25 are respectively flush with the upper surface, the lower surface, and the side edges of the floor panel 2, and the closing plate 4 is the opening 1 of the floor panel 2. Cover.

  Thereafter, if the tile receiver 23 is supported by the panel receiver 21 and the tile carpet 23 is placed, the floor panel 2 becomes smooth between the upper surface of the floor panel 2 and the outer surface of the closing plate 4. Even when arranged, since the outer surface of the connecting portion 25 is arranged on the side edge of the floor panel 2, the edges of the adjacent floor panels 2 and 2 can be in close contact with each other. Further, when a vertical load is applied to a position directly above the opening 1 of the lid member 5, a load acts on the closing plate 4 in the shearing direction at the boundary between the opening 1 and the flange. Is borne not only in the closing plate 4 but also in the connecting portion 25 straddling the flange portion and the opening 1 continuously to the closing plate 4, and also in the mounting piece 3 straddling the flange portion and the opening 1 in the same manner. Is also borne by the connecting portion 25. Therefore, the lid member 5 is not easily deformed and broken by the load described above, and similarly, the flange portion of the floor panel 2 is not easily deformed and broken.

  The floor panel 2 described above can improve work efficiency at the site by mounting the lid member 5 in the lid housing recess 6 in advance in the factory and carrying it into the construction site. In this case, since the lid member 5 is firmly fixed to the floor panel 2 by the locking projections 9, it is difficult for the lid member 5 to fall off due to vibration during transportation. In order not to jump out from the side edge, flat stacking can be easily performed.

  On the other hand, when the outlet 24 is provided in the opening 1 as described above at the construction site, the lid member 5 is removed from the lid accommodating recess 6, but the floor panel 2 is provided to accommodate the lid member 5. A preliminary accommodating recess 7 is formed. In this embodiment, as shown in FIG. 1 and the like, the preliminary accommodating recess 7 is disposed at the center of the side edge of the floor panel 2 that faces the side edge where the opening 1 is formed. The preliminary accommodating recess 7 is formed on the side edge in the same size as the above-described lid accommodating recess 6. That is, the front side accommodating recess 7 a and the back side accommodating recess 6 b having the same size as the front side accommodating recess 6 a. The rear-side preliminary accommodating concave portion 7b and the side-edge-side concave portion 7c have the same size as the back-side preliminary accommodating concave portion 7b. In addition, a locking hole 8 is formed in each of the front-side preliminary accommodating recess 7a and the back-side preliminary accommodating recess 7b in the same manner as the front-side accommodating recess 6a and the like.

  Therefore, if the lid member 5 is accommodated in the preliminary accommodating recess 7, the lid member 5 can be stored in association with the floor panel 2 in which the opening 1 is closed by the lid member 5, and in this state. The floor panel 2 has a smooth upper surface, lower surface, and side edges, the tile carpet 23 laid on the upper surface is held smooth, and the adjacent floor panels 2 and 2 can be closely contacted with each other.

  Further, in this embodiment, when the lid member 5 is not accommodated in the preliminary accommodating recess 7, that is, when the opening 1 is closed with the lid member 5, the preliminary accommodating recess 7 does not disturb the smoothness of the upper surface of the floor panel 2. In order to do so, a convex portion 10 is formed in the preliminary accommodating concave portion 7, and a through hole 11 is formed in the lid member 5 described above.

  The convex portion 10 is formed in a floating island shape in the surface side preliminary accommodating concave portion 7a, and in this embodiment, in consideration of the size and smoothness of the surface side preliminary accommodating concave portion 7a, as shown in FIG. It is provided in the shape. This convex part 10 is formed in the taper shape in which a side wall goes to a protrusion front-end | tip. On the other hand, in the mounting piece 3 of the lid member 5, as shown in FIG. 2, when the mounting piece 3 is accommodated in the surface side preliminary accommodating concave portion 7a, the through holes 11 for receiving the convex portions 10 described above are scattered. Will be opened.

  Therefore, when the lid member 5 is not accommodated in the preliminary accommodating recess 7, the tile carpet 23 laid on the upper surface of the floor panel 2 is supported by the convex portion 10 although it is scattered, and the recess due to the preliminary accommodating concave portion 7 is inconspicuous. Is done. On the other hand, when the lid member 5 is accommodated in the preliminary accommodating recess 7, as shown in FIG. 2, the mounting piece 3 is accommodated in the surface side preliminary accommodating recess 7 a, that is, the above-described lid member 5 is attached to the lid accommodating recess 6. By flipping up and down with respect to the housing posture, the lid member 5 is prevented from protruding from the upper surface of the floor panel 2.

  FIG. 5A shows a first modification of the present invention. Note that the same components as those of the above-described embodiment in this modified example and other modified examples described later are denoted by the same reference numerals in the drawings, and description thereof is omitted. In this modification, the opening 1 formed in the floor panel 2 in a notch shape is formed at the opposite side edge of the floor panel 2. A lid housing recess 6 is formed at the peripheral edge of each opening 1, and the preliminary housing recess 7 is formed at each edge adjacent to the edge where the opening 1 is formed. Therefore, in this modification, the number of outlets 24 installed can be increased, and the degree of freedom of arrangement of outlets 24 can be increased.

  FIG. 5B shows a second modification. In this modification, the floor panel 2 is formed as a wooden particle board or the like. The lid member 5 is formed with a smaller thickness in accordance with the strength of the floor panel 2, and thus the convex portion 10 described above is omitted by reducing the depth of the preliminary accommodating concave portion 7.

  In the above-described embodiments and modifications, the lid member 5 is formed of a metal material. However, the lid member 5 can be formed of, for example, a high-strength synthetic resin material. In addition, the size, shape, and arrangement of the convex portion 10 formed in the preliminary accommodating concave portion 7 can be changed according to the size of the preliminary accommodating concave portion 7 and the smoothness of the tile carpet 23 laid on the upper surface of the floor panel 2. Is possible.
