Description

  TECHNICAL FIELD The present invention relates to an outdoor double floor that can be used for a building entrance, a surrounding road surface, a promenade, and the like.

  The double floor is often used to form a space used for wiring and air conditioning under the floor in the building, but is also used outdoors (for example, Patent Document 1). Patent Document 1 discloses an outdoor double floor (outdoor installation double floor) that has water permeability and has a space (wiring / piping space) used for wiring and air conditioning inside (floor panel). A plurality of (main bodies) are arranged adjacent to each other, and a height-adjustable support leg is provided between the ground and each floor panel main body (Patent Document 1, [Claim 1]).

  The floor panel which constructs the outdoor double floor disclosed in Patent Document 1 forms a space used for wiring and air conditioning by separating the front plate and the back plate via a spacer. Moreover, the floor panel which construct | assembles the outdoor double floor which patent document 1 discloses is equipped with water permeability as a whole by comprising a surface board with a water-permeable asphalt and a back surface board with a punching metal. As a result, when constructing an outdoor double floor, even if the floor panels are arranged closely, the rain water that has fallen on the surface plate does not accumulate and flows down to the ground surface (Patent Document 1, [0008]).

  Moreover, the floor panel which construct | assembles a double floor can also see the structure which combined asphalt and a metal in consideration of weather resistance like the outdoor double floor which patent document 1 discloses, for example, but generally In many cases, the front plate and the back plate are each configured as a hollow structure made of a metal plate. When these floor panels are used for indoor double floors, carpets are often affixed to surface plates made of metal plates. However, in recent years, in order to improve aesthetics, stone tiles and the like molded into a plate shape are used. It may be attached (Patent Document 2 or Patent Document 3).

  The double floor disclosed in Patent Document 2 is constructed by detachably bonding and fixing floor tiles formed by firing stone or clay on the surface of an existing double floor (free access floor) (patent) Reference 2 [Claim 1]). The joints between the floor tiles are filled with joint tapes affixed to the side surfaces of the respective floor tiles (Patent Literature 2, [Claim 4] to [Claim 6]). Patent Document 2 mentions advantages that floor tiles can be replaced or joint construction is simplified by a configuration in which floor tiles are attached to an existing double floor (Patent Document 2 [0006]).

  The double floor disclosed in Patent Document 3 has a cross-corner member disposed on the upper surface of the existing double floor, and an adhesive elastic sheet and a non-adhesive elastic sheet are disposed on the upper surface so as to be in close contact with the adhesive sheet. The floor stone material is spread in accordance with the cross corner member, and the joint material is filled in the joints of the adjacent floor stone materials (Patent Document 3 [Claim 1]). Patent Document 3 has an advantage that the construction is easy and the stone member can be replaced by the structure in which the stone member is attached to the existing double floor, or the adhesive elastic property between the existing double floor and the stone member. It is mentioned that there is an advantage that the impact and reverberation sound during walking are reduced by interposing a sheet and a non-adhesive elastic sheet (Patent Document 2, [0008]).

  The double floor can be constructed relatively easily and can be easily replaced, and has the advantage that a space used for wiring and air conditioning can be formed under the floor. As such, outdoor double floors have also been proposed. However, as can be seen in Patent Document 2 or Patent Document 3, an outdoor double floor excellent in aesthetics, specifically, an outdoor double floor in which stone tiles are arranged on the surface has not been seen yet. That is, the outdoor double floor has a problem that cannot be seen in the indoor double floor, and the double floor disclosed in each of Patent Documents 1 to 3 is simply combined to construct an outdoor double floor. It is thought that it is not possible to do.

  As disclosed in Patent Document 1, the outdoor double floor requires water permeability or drainage for the arranged floor panels in consideration of drainage of rainwater. For this reason, if a stone tile is affixed on the floor panel used for the outdoor double floor, since water permeability or drainage will be lost, a stone tile cannot be simply affixed on the surface of a floor panel. This is the same even when the floor panel is made of a stone panel as it is. From this, it becomes necessary to impart water permeability or drainage to a floor panel to which stone tiles are attached or a floor panel composed of stone panels.

  In order to impart water permeability or drainage to the floor panel, in the double floor seen in Patent Document 2 or Patent Document 3, open the joints that have been closed, and provide a gap between adjacent floor panels, It is conceivable to form a drain. However, in the case of an outdoor double floor, not only rain but also the influence of wind must be considered. Specifically, when the drainage grooves are formed by opening the joints of the floor panels that make up the outdoor double floor, there is no need to hold down the floor panel by closing the joints, so wind blows on the floor panel surface. The negative pressure causes the floor panel to float and cause a positional shift, or the worst floor panel is turned over.

  Although it is conceivable to prevent the floating by using the floor panel itself as a heavy object to the problem due to the wind of the outdoor double floor, there arises a problem that the advantage of easy construction is impaired. In addition, as seen in indoor double floors, it is considered to use a fixing structure that presses the corners against the pillars on which the corners that the four floor panels meet are put together. If the fixed structure is used for a floor panel composed of stone panels, the fixed structure may be visually recognized from the outside, and the aesthetics may be impaired, or the joint width may widen due to the fixed structure and the heel of the high heel may fall. Since it comes out, it is not preferable. In addition, fine work is required at the corners of the stone panel according to the fixed structure, which may increase the manufacturing cost of the floor panel.

  In this way, it is necessary to consider the problem that the floor panel floats due to rainwater drainage or the wind blown on the surface of the floor panel in the outdoor double floor. It is not possible to construct an outdoor double floor with excellent aesthetics simply by pasting it on the floor or using a stone panel as a floor panel. Therefore, in order to be able to construct an outdoor double floor with excellent aesthetics using a floor panel composed of stone panels, it is possible to drain rainwater and to suppress the floating of the floor panel due to wind blowing on the floor panel or The construction or structure that was prevented, was easy to construct, and was able to replace floor panels (stone panels) as needed was studied.

What was developed as a result of the study was an outdoor double floor constructed by arranging a large number of floor panels supported by pillars arranged on the foundation surface. A plurality of floor panels are placed on the support surface at the upper end of the support column that stands upright on the foundation surface with the side walls facing each other leaving a gap of the joint width, and aligned on the same straight line. The fixing member is inserted into the joint across the mating convex surface, and the hooking claws provided at both ends of the fixing member are hooked to the support surface, thereby fixing the position to the support column. It consists of a horizontal bar with a length that cuts through the engaging convex surfaces, a vertical bar that is lowered from each of the horizontal bars, and a latching claw provided at the lower end of each vertical bar, and either the horizontal bar or the vertical bar Alternatively, both can be elastically deformed, and the rod is inserted into the vertical bar from above. Tsu is bet the outdoor double floor ing provided. In addition, the fixing member is lowered from each of the horizontal bar and a horizontal bar having a length that intersects the circumferentially equal interval by the number of floor panels that abut the corners, and that vertically cuts the engaging convex surface that is aligned on the same straight line. It consists of a vertical bar and a latching claw provided at the lower end of each vertical bar. Either one or both of the horizontal bar and the vertical bar can be elastically deformed, and a slit for inserting the rod body from above can be provided in the vertical bar. Good .

  The corners of the floor panel are abutted by four corners based on a square in plan view, but if the engaging convex surfaces provided on the respective side surfaces are arranged on the same straight line, for example, an isosceles triangle in plan view that divides the square into eight is obtained. The corners may be abutted one by one. “Latching the hooking claws provided at both ends of the fixed member on the support surface” means that the hook is directly hooked on the support surface at the upper end of the column, and the member integrated with the support surface (for example, the support surface cover). Including the case of hanging.

  In the outdoor double floor according to the present invention, the floor panel having the side surfaces facing each other leaving a gap of the joint width is fixed to the column by the fixing member. Thereby, the clearance gap formed between the side surfaces which an adjacent floor panel opposes can be utilized as a drainage groove. Further, since the plurality of floor panels are connected via a fixing member and are fixed to the column by the fixing member, the negative pressure generated by the wind blowing on the surface of the floor panel causes the floor panel to It doesn't float up and invites misalignment, and the worst floor panel is not turned over.

  If the floor panel which comprises the outdoor double floor of this invention provides an engagement convex surface in the side surface of the corner | angular part of a stone panel, the outdoor double floor in which a stone panel is located can be constructed | assembled. The engaging convex surface provided on the side surface of the corner of the stone panel may be formed by directly processing the stone panel itself. However, it is easier to configure the floor panel by attaching a cover member to a corner and providing an engagement convex surface on the side surface of the cover member. In this case, there is an advantage that the thickness and outer shape of the required engaging convex surface can be easily changed simply by changing the cover member.

  In addition, if the floor panel has a cover member attached to a corner and the bottom surface of the cover member is a raised part whose height can be adjusted, the height of the raised part can be adjusted to adjust the height of the column. The unevenness of the panel can be easily eliminated. Further, when the floor panel is formed of a stone panel (particularly, a natural stone stone panel), the variation in the thickness of the stone panel can be absorbed by adjusting the height of the raised portion. The raised portion can be exemplified by a configuration in which the height is mechanically adjusted by, for example, a combination of a bolt and a nut, or a configuration in which the height is adjusted by cutting with a resin member that is easy to cut, if necessary.

  Specifically, the fixing member includes a horizontal bar having a length that vertically cuts the engaging convex surfaces arranged on the same straight line, a vertical bar that is lowered from each of the horizontal bars, and a latching claw provided at a lower end of each vertical bar. A configuration in which the fixing member is exemplified by a horizontal bar that is linear in a plan view can be exemplified. The horizontal bar and the vertical bar are names that mainly extend in the horizontal direction (horizontal bar) or the vertical direction (vertical bar). For example, the horizontal bar is curved, or the vertical bar is in the opposite direction of the latching claw. It may be inclined in the direction or outward.

  In addition, the fixing member is lowered from each of the horizontal bar and a horizontal bar having a length that intersects the circumferentially equal interval by the number of floor panels that abut the corners, and that vertically cuts the engaging convex surface that is aligned on the same straight line. When a vertical bar and a latching claw provided at the lower end of each vertical bar, that is, a fixing member in which a horizontal bar having a straight line in plan view intersects in a horizontal plane, a plurality of floor panels that abut corners are provided. The position can be fixed to the support more stably.

  For example, when the corners of four floor panels that are square in plan view are abutted, even if the straight horizontal bar is a single fixing member, the horizontal bar vertically cuts together the engaging convex surfaces of the floor panels facing the side surfaces. Therefore, the position of the four floor panels can be fixed to the column with one fixing member. However, in the case of a fixing member where the straight horizontal bars intersect, the engaging convex surfaces provided on the two side surfaces sandwiching the corners of each floor panel are pressed down by the fixing member, so that they can be positioned more stably on the column. Fixed.

  The fixing member can be removed by removing the latching claws latched on the support surface of the support column, and the floor panel can be replaced. In this case, the fixing member may be configured such that one or both of the horizontal bar and the vertical bar can be elastically deformed, and a slit for inserting the rod body from above is provided in the vertical bar. Either one or both of the horizontal bar and the vertical bar is made of resin or thin metal, or the whole is made of resin, and the fixing member gives elasticity to either or both of the horizontal bar and the vertical bar. To do. The fixing member that engages the latching claw with the support surface of the support column, when the rod inserted into the slit from above is tilted in the engagement direction of the latching claw, the vertical bar relatively moves in the engagement direction of the latching claw. The latching claw can be removed from the support surface.

  The outdoor double floor of the present invention is easy to suppress or prevent the floor panel from being lifted by negative pressure generated by the wind blown on the surface of the floor panel without making the floor panel using the stone panel heavy. Because it can be fixed in position, construction is easy and the floor panel can be replaced if necessary. Outdoors (where there are buildings nearby) or outdoors (where there are few buildings nearby) where the outdoor double floor is installed, where the wind blows locally without interruption, and where the wind is strong (eg high places) In particular, the effect of suppressing or preventing the floating of the floor panel is preferable as the performance required for the outdoor double floor. In addition, the outdoor double floor of the present invention keeps the open joints below the width where the heel of the high heel does not fall by making the fixing member thin while opening to drain rainwater with the joints as drainage grooves. be able to.

  The advantage that the floor panel using stone panels can be easily fixed is that it is inserted into the joint gap across the engaging convex surface provided on the side of the corner of the floor panel, and the latching claw is latched to the support surface of the column This is the effect of the fixing structure of the fixing member. Such a fixing structure for pressing the engaging convex surface with a fixing member facilitates the construction of the outdoor double floor of the present invention. Moreover, the drainage of rainwater is the effect of leaving the side walls of the arranged floor panels facing each other and leaving a joint gap. And replacement | exchange of a floor panel is an effect by the fixing member which can remove a latching claw from the support surface of a support | pillar by elastically deforming one or both of a horizontal bar or a vertical bar.

  Thus, the outdoor double floor of the present invention forms a space used for piping and drainage in addition to wiring and air conditioning between the foundation surface and the floor panel, and electric wiring and dry mist for street lights and illumination. It is possible to install water pipes, etc., without requiring large-scale civil engineering work. In addition, the outdoor double floor of the present invention can be used as an entrance to commercial buildings and condominiums that require particularly aesthetics, since rainwater can be drained firmly while using stone panels as floor panels. This means that the outdoor double floor can be used in situations where it has not been used. The outdoor double floor of the present invention can be used indoors as a double floor using a stone panel, and has an effect that the usable range is both indoors and outdoors.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIG. 1, the outdoor double floor of the present invention has corners of a square floor panel 1 in a plan view on pillars 4 arranged at equal intervals on a flat base surface, for example. The drainage grooves 13 are formed by opening the joints of the adjacent floor panels 1 and supporting them four by one. The outdoor double floor of the present invention is the same as the indoor double floor except that the open joint is used as the drainage groove 13. This means that the outdoor double floor of the present invention can be constructed and used indoors instead of the indoor double floor.

  As shown in FIG. 2, the floor panel 1 is made of a metal having a square shape in plan view, in which a rectangular reinforcing flange 121 is formed by bending the back side of a stone panel 11 having a square shape in plan view on the back surface of a stone panel 11 having a square shape. The bottom plate 12 is bonded and integrated. The outdoor double floor of the present invention is provided with an engagement convex surface 22 on the side surface of the stone panel 11, and the engagement convex surface 22 is engaged with and fixed to the support surface 41 of the support column 4 using the fixing member 3. It can be constructed without the bottom plate 12. The floor panel 1 of this example is provided with a bottom plate 12 in order to prevent the stone panel 11 from falling if the stone panel 11 is broken and cracked.

  The stone panel 11 of this example has a chamfered lower peripheral edge, and a lower peripheral edge is cut obliquely to form a retaining surface 111, and the reinforcing flange 121 of the bottom abutment plate 12 is within the range of the retaining surface 111. So that the side surface of the stone panel 11 and the outer surface of the reinforcing flange 121 are flush with each other, or the outer surface of the reinforcing flange 121 is kept away from the side surface of the stone panel 11. As a result, the reinforcing flange 121 of the bottom abutting plate 12 does not protrude from the outer peripheral edge of the stone panel 11 in plan view, and the stone panels 11 can be stacked closely by bringing the side surfaces into contact with each other for storage and transportation. .

  The holding surface 111 is only required to hold the outer surface of the reinforcing flange 121 from the side surface of the stone panel 11, and for example, a concave surface that is a transfer structure of the reinforcing flange 121 may be formed. However, since it is difficult to process the concave surface by providing a step in the stone panel 11, the stone panel 11 of this example is cut obliquely to form the inclined holding surface 111. For this reason, when the reinforcing flange 121 of the bottom surface abutting plate 12 is held so as to fit in the holding surface 111, a cutout groove 112 having a triangular cross section sandwiched between the holding surface 111 and the upper end surface of the reinforcing flange 121 is formed.

  The notch groove 112 sandwiched between the holding surface 111 and the upper end surface of the reinforcing flange 121 thus formed engages the engaging protrusion 221 of the cover member 2 so that the cover member 2 is attached to the corner of the floor panel 1. It functions as an engaging groove (see FIG. 9 below). In addition, the notch groove 112 sandwiched between the holding surface 111 and the upper end surface of the reinforcing flange 121 is a protruding margin where excess adhesive (urethane resin adhesive) that adheres the floor contact plate 12 to the stone panel 11 protrudes and accumulates. Also works.

  The floor panel 1 of this example does not process the reinforcing flange 121 of the stone panel 11 or the floor surface abutment plate 12, but attaches the resin cover member 2 having the engaging convex surface 22 to the corners, An engagement convex surface 22 is provided. The floor panel 1 is shipped with a cover member 2 attached at a manufacturing plant. For example, the floor panel 1 may be stored or transported alone and attached to the floor panel 1 as appropriate at the construction site of an outdoor double floor. Good. The cover member 2 of the present example is a resin-made integral molded product, and does not require assembly during manufacture. In addition, the cover member 2 can be used as a protective member that protects the corners of the stone panel 11 from the outside. The height is adjusted by shaving.

  The cover member 2 of this example has a substantially square shape in plan view that is brought into contact with the back surface of the back plate 12 of the floor panel 1 (in FIG. 8, the bottom surface side of the substantially triangular shape is cut out on the outer periphery of the arc of the support surface cover 5. The base 21 is provided with an engagement convex surface 22 on the upper surface side of the base 21 and a raised portion 23 on the rear surface side of the base 21. The engaging convex surface 22 makes a vertical flange bent over two sides of the orthogonal relationship that coincide with the corners of the floor panel 1 come into contact with the side surface of the floor panel 1 (side surface of the stone panel 11), and the floor is equal to the thickness of the vertical flange. It is configured to project from the side surface of the panel 1. Although the engaging convex surface 22 of this example is continuous with the bent vertical flange, it may be two independent engaging convex surfaces 22 in accordance with the side surfaces of the stone panel 11.

  The raised portion 23 is a resin block in the form of a quarter of a flat view that fits in a range surrounded by a peripheral stopper 511 and a partition plate 53 of the support surface cover 5 described later, and is orthogonal to the corner of the floor panel 1. These two sides are provided so as to protrude from the back surface of the base 21 from a position where the thickness of the engaging convex surface 22 is reduced. The raised portion 23 of this example is made of resin and should be appropriately cut to absorb the difference in thickness of the stone panel 11 processed from non-uniform natural stone, and the thickness of the floor panel 1 including the cover member 2 is reduced. Let them adjust.

  As described above, the cover member 2 of this example has the engagement protrusion 221 formed on the inner side of the engagement convex surface 22 and the notch groove 112 (= the holding surface 111 and the reinforcing flange 121) formed on the side surface of the floor panel 1. In addition to engaging with the notch groove 112) sandwiched between the upper end surfaces of the floor panel 1, a mating projection 221 provided on the base 21 is provided on the stone panel 11 through a mating hole 122 provided on the back plate 12 of the floor panel 1. It is fitted into the fitting hole (not shown) and attached to the corner of the floor panel 1. Thus, the mounting of the cover member 2 of the present example to the floor panel 1 is only mechanical engagement and fitting. However, when the mounting to the floor panel 1 is desired to be shared, for example, the base 21 is attached to the back plate 12. You may adhere to.

  The fixing member 3 has a vertical bar 32 lowered from each end of the horizontal bar 31 that is linear (upper left in FIG. 2) or cross (lower right in FIG. 2), and is opposed to each lower end of the vertical bar 32. This is an integrally molded product made of resin and provided with latching claws 33 protruding in the direction. Regardless of whether the horizontal bar 31 is linear or cross-shaped, the horizontal bar 31 and the vertical bar 32 aligned on the same line are aligned with the contour shape drawn by the upper end surface of the engaging convex surface 22 aligned on the same line. The straight bottom surface (the surface facing the engaging convex surface 22) is sandwiched between the arc-shaped bottom surfaces of the vertical bars 32 so that the linear bottom surface and the arc-shaped bottom surface are continuous.

  The four floor panels 1 whose corners face each other around the column 4 have four engagement convex surfaces 22 arranged on the same straight joint. From this, if it is the fixing member 3 (upper left side in FIG. 2) composed of the linear horizontal bar 31 that fits in the joint, the four floor panels 1 whose corners are abutted around the column 4 can be pressed. However, since the floor panel 1 of this example is provided with the engaging convex surface 22 on each of the two side surfaces sandwiching the corner portion, and four engaging convex surfaces 22 arranged on each intersecting joint, there are a total of eight. It is preferable that all of the four engaging convex surfaces 22 arranged in the intersecting joints can be pressed down by the fixing member 3 formed of a horizontal bar 31 having a shape. The outdoor double floor of this example will be described as an example using the fixing member 3 basically composed of a cross-shaped horizontal bar 31.

  The fixing member 3 of this example comprising a cross-shaped horizontal bar 31 has a horizontal bar 31, a vertical bar 32, and a latching claw 33 that are formed in a width that fits in the joint, and a horizontal bar that is a square bar having the above-mentioned width. The bar 31 is easily elastically deformed. Accordingly, when the removal jig 6 inserted in the slit 321 provided in the vertical bar 32 is tilted, the horizontal bar 31 is bent and elastically deformed, and the latching claw 33 can be removed from the latching recess 521 of the support surface cover 5. it can. The fixing member 3 of this example is provided with a pair of deformation suppressing concave surfaces 311 sandwiching the boundary between the horizontal bar 31 and the vertical bar 32 so that the bending of the horizontal bar 31 does not reach the vertical bar 32. The deformation suppressing concave surface 311 is also used as a concave surface for punching through which a mold for forming the latching claw 33 is passed.

  The support column 4 has the same configuration as that used for an indoor double floor, and has a square main surface 43 in plan view at the lower end of the main column 43 that can be adjusted in overall length, and a circular support surface 41 in plan view at the upper end of the support column body 43. Is provided. The column main body 43 is composed of a metal upper cylinder and a lower cylinder to be screwed together, and the height is adjusted by the screwing amount of the both, and both are fastened by a fixing screw to maintain the height. The ground surface 42 is a metal plate that can be attached and detached at four corners with a tilt adjusting screw. After the tilt adjustment, the ground surface 42 is bonded and fixed to the base surface with an adhesive (epoxy silicone resin adhesive).

  The support surface 41 is a metal disk having a size on which the raised portion 23 of the cover member 2 attached to each corner of the four floor panels 1 to be abutted is placed. The support surface 41 of this example is not placed on the raised portion 23 of the cover member 2 mounted directly on the corner of the floor panel 1 but on the flat plate 51 of the support surface cover 5 described later. From this, the support surface 41 is provided with four positioning holes 411 at the square corners in plan view for fitting the positioning protrusions 54 projected from the back surface of the flat plate 51 of the support surface cover 5.

  The support surface cover 5 is fixed in a specific direction with respect to the support surface 41 by inserting positioning protrusions 54 into positioning holes 411 provided in the support surface 41. Further, the cover member 2 attached to the corner of the floor panel 1 is placed in a specific direction with respect to the support surface cover 5 according to the partition plate 53 provided on the support surface cover 5. From now on, the support surface 41 in this example is idle with respect to the upper end of the support column body 43 (the upper end of the upper cylinder) so that the posture of the floor panel 1 in the horizontal plane is not affected by the height adjustment of the support column 4. The orientation of the support surface cover 5 fixed to the surface 41 is not influenced by the column main body 43.

  The support surface cover 5 is a resin member having a flat cylindrical shape with an open bottom, and forms a skirt portion 52 by lowering the peripheral surface downward from the outer peripheral edge of the flat plate 51 having a circular shape in plan view. A posture in which a cross-shaped partition plate 53 in plan view is provided on the upper surface of the face plate 51, and a U-shaped cross-sectional peripheral stopper 511 configured by an arcuate wall surface following the outer peripheral edge of the flat plate 51 is opened inward in the radial direction. 12 are provided at intervals of 30 degrees in the circumferential direction, and drainage channels 512 extending along the partition plate 53 and drainage channels 512 extending in the radial direction between the peripheral stoppers 511 are formed. Each drainage channel 512 is connected to each other.

  The support surface cover 5 is placed on the support surface 41 at the upper end of the support column 4, and a positioning projection 54 projected from the back surface of the flat plate 51 is fitted into the positioning hole 411 of the support surface 41 to fix the position. The skirt portion 52 is fitted so as to cover the support surface 41 when the support surface cover 5 is fixed to the support surface 41 at the upper end of the support column 4. For this reason, the latching claw 33 of the fixing member 3 passes through the trapezoidal concave recesses 521 provided in the skirt portion 52 of the support surface cover 5 at equal intervals in the circumferential direction, and the peripheral edge of the support surface 41 at the upper end of the column 4 Hang from below.

  The partition plate 53 divides the flat plate 51 into quarters, and forms an area on which the cover member 2 attached to the corner of the floor panel 1 is placed. The entire partition plate 53 of this example does not contact the side surface of the raised portion 23 of the cover member 2 but makes the contact rib 531 provided at a substantially intermediate position line-contact with the side surface of the raised portion 23. Thereby, it is not necessary to increase the processing accuracy of the partition plate 53 itself, and the contact rib 531 is surely brought into line contact with the side surface of the raised portion 23 to suppress the laying interval (laying pitch) of the floor panel 1 from shifting. To prevent.

  The peripheral stopper 511 is paired with the partition plate 53 to form a section on which the raised portion 23 of the cover member 2 mounted on the corner portion of the floor panel 1 is placed, and the raised portion 23 is a flat plate 51 of the support surface cover 5. To prevent it from coming off. The peripheral stopper 511 of this example is intermittently provided in the circumferential direction in order to form a drainage channel 512 extending in the radial direction in order to drain rainwater and the like entering the flat plate 51 to the outside. The point that such a drainage channel 512 is provided in the support surface cover 5 is a structure peculiar to the outdoor double floor.

  In the outdoor double floor of this example, the corners of the floor panels 1 are first placed so that the corner portions of the floor 4 are abutted against the support surface cover 5 that is placed on the support surface 41 at the upper end of the support column 4 arranged in advance on the base surface. The cover member 2 mounted on the part is placed (see FIG. 3), and then the intersection of the cross-shaped horizontal bars 31 is made to coincide with the center where the corner part is abutted, and the fixing member 3 is placed in the joint gap formed by the floor panel 1 Inserting (see FIG. 4, for convenience of explanation, illustration of the floor panel in front of the drawing is omitted), and the latching claw 33 of the fixing member 3 is latched to the support surface 41 through the latching recess 521 of the support surface cover 5 (FIG. 5), the installation of the floor panel 1 is completed.

  As described above, the installation of the support column 4 with respect to the foundation surface requires the adjustment of the inclination of the installation surface 42 and the height adjustment of the support column body 43. The raised portion 23 of the cover member 2 mounted on the corner portion of each floor panel 1 is placed on the support surface cover 5 that covers the support surface 41 at the upper end of the support column 4, and the fixing member 3 is inserted into the gap between the joints. A simple procedure is sufficient to hook the latching claw 33 of the fixing member 3 to the support surface 41 through the latching recess 521 of the support surface cover 5. Such a simple construction provides the advantage of facilitating the construction of the outdoor double floor and the advantage that the floor panel 1 can be easily replaced by not using an adhesive or the like.

  As shown in FIGS. 6 to 8, the fixing member 3 fits perfectly in the joint gap formed by the floor panel 1 that faces the side, and has a shape that follows the upper end surface of the engaging convex surface 22 of the cover member 2. With the bottom surfaces of the horizontal bar 31 and the vertical bar 32 in contact with the upper end surface of the engaging convex surface 22, the latching claw 33 at the lower end of the vertical bar 32 is provided on the skirt portion 52 of the support surface cover 5. It hooks on the support surface 41 through the recess 521 and is prevented from coming off upward. The floor panel 1 is fixed in position when the engaging convex surface 22 of the cover member 2 attached to the corner is pressed into the horizontal bar 31 of the fixing member 3.

  The fixing member 3 may leave a slight gap from the engaging convex surface 22 (see FIG. 7). When the floor panel 1 is lifted by the negative pressure generated by the wind blown on the surface of the floor panel 1, the engaging convex surface 22 lifts the horizontal bar 31 of the fixing member 3 to bend upward and bends upward. Tilt inward in the radial direction. Thereby, the latching claw 33 provided at the lower end of the vertical bar 32 is more securely latched to the support surface 41 through the latching recess 521 of the support surface cover 5. Thus, even if the fixing member 3 is separated from the engaging convex surface 22, the floating of the floor panel 1 can be suppressed or prevented.

  The floor panel 1 of this example is configured by overlapping a stone panel 11 processed from natural stone and a metal bottom abutment plate 12. Here, the thickness of the bottom plate 12 is constant, but the thickness of the stone panel 11 formed by processing natural stone is not necessarily constant. The floor panel 1 may not have a constant thickness, but the surface of the floor panel 1 needs to be flush with the outdoor double floor walking surface. Therefore, as shown in FIG. 9, the raised portion 23 of the cover member 2 is shaved so that the surface of the floor panel 1 is flush with the surface, and the thickness from the surface of the floor panel 1 to the bottom surface of the raised portion 23 is constant. The height is adjusted so that the heights of the left and right raised portions 23 are different in the figure.

  In the outdoor double floor of the present invention, the procedure for installing the floor panel 1 is simple, but the procedure for removing the floor panel 1 is also simple. Specifically, first, as shown in FIG. 10 (for convenience of illustration, the vertical bar on the near side is not shown), a removal jig 6 that is a metal bar is provided on the vertical bar 32 of the fixing member 3. Insert into slit 321. Since the fixing member 3 of this example has lowered a total of four vertical bars 32 from each end of the horizontal bar 31 on the cross in plan view, there are also four slits 321. The removal jig 6 may be assigned four metal rods to each slit 321 or may be configured such that the four metal rods are assembled so as to be tiltable in the radial direction.

  When the upper half of the removal jig 6 inserted into the slit 321 is tilted in the engagement direction (radius inward) of the latching claw 33, the horizontal bar 31 is elastically deformed downward and the lower half is hooked relatively. The vertical bar 32 provided with the slits 321 is tilted in the releasing direction (radius outward) of the pawl 33 and is lifted according to the lower half of the jig 6. Accordingly, as shown in FIG. 11 (for convenience of illustration, the vertical bar on the near side is not shown), the latching claw 33 can be detached from the latching recess 521 of the support surface cover 5 that has been latched. .

  The fixing member 3 in which the horizontal bar 31 is bent and the vertical bar 32 is opened radially outward is inserted into the slit 321 as shown in FIG. 12 (for convenience of illustration, the vertical bar on the near side is not shown). The lifting jig 6 can be lifted upward and pulled out together. Thereby, the floor panel 1 can be removed from the support surface cover 5, and arrangement | positioning replacement, old and new replacement, etc. can be made freely. The fixing member 3 can be reused if the removal jig 6 is pulled out from the slit 321 and the bent horizontal bar 31 is restored. Thus, it is also a feature of the present invention that the floor panel 1 can be replaced and the fixing member 3 can be reused.
