Description of the invention [Technical field to which the invention belongs] The present invention relates to a structure of a double-floor pillar used in a double-floor system formed by laying a floor panel with an underground space between the ground and the ground. A pillar structure capable of reducing the number of parts, assembling man-hours, and reducing costs. [Prior art] In recent years, based on the development of communication technology, in order to arrange network lines or other various cables under the floor, the floor structures of buildings such as buildings are often constructed with a space between the floor and the ground (under the floor). The floor panel is laid as a double floor structure at a specific height position. In order to make such a double-layered floor structure, it is necessary to support the floor panel from the ground by supporting pillars (for example, 'refer to Patent Documents 1 and 2). Figures 6 to 9 show an example of the structure of a conventional support for a double floor. This double-layer floor pillar structure is composed of a base portion 10 placed on the floor surface 100, and a slightly central cylindrical leg portion 102 mounted on the base portion 100 and riveted at the lower end portion. And a male screw portion 104 which is screwed with a female screw portion 103 formed on the inner peripheral surface of the foot portion 102, and is inserted into the foot portion 102 to adjust its height freely Position the panel support screw 1 05, and riveting the panel support screw in this panel! 05, the front panel receiving member 106, and a panel fixing member for fixing the floor panel 107 placed on the panel receiving member 106 to the panel receiving member 106] 08, and fixing the height of the panel receiving member 106 Positioning lever] 09 200530472 (2). The base 101 is formed by plating the surface of a slightly square steel plate. In order to flatten the bottom surface (mounting surface) of the support structure for double-floor stably placed on the surface 100, a slightly annular rib 110 is formed at the base portion 101 below. In this base portion 101, a slightly annular rib 1 10 formed at a position separated by the leg portion 102 is in contact with the outer peripheral portion and the floor surface 100 to support a double-floor pillar structure. • The feet 102 are formed by plating the surface of the steel plate with a cylindrical shape. This leg portion 102 is fixed to the aforementioned base portion 101 by inserting the lower end portion 102a into a slightly hole portion 11 formed in the base portion 101, and crimping the lower end portion 102a to the outer peripheral edge portion of the hole portion 111. A female screw 103 is formed on the inner surface of the leg portion 102 along its axial direction. In addition, the foot portion 102 may be fixed to 101 ° by welding. The panel support screw 105 has a male screw portion 104 on its outer peripheral surface that is screwed to a female screw portion 103 formed on the front portion 102. The female screw portion 103 and the male screw portion 104 can freely adjust the height position of the opposing portion 102. In addition, the panel support screw 105 is formed by inserting the mounting hole portion 112 in the lower surface of the panel receiving member 106 into the insertion portion 105a, and crimping the front end portion 105a to the edge portion of the mounting hole portion 112. The aforementioned panel receiving member 106 is fixed. The panel receiving member 106 is composed of a disc-shaped body portion 1 1 4 having a floor panel 107 on-board mounting portion Π 3, and a cylindrical protruding portion 1 protruding upward from the center of the body portion 1] 5 Formed. This slab floor has a center with a protruding lower end at the base of the tooth. The foot fits at the base of the front end. 114 Panel-6- 200530472 (3) The receiving member 1 06 series and the previous base 1 ο 1 and foot 102 are the same, and are formed by plating on the surface of the steel plate. A truncated circular engaging projection portion 1 1 7 is formed on the upper surface of the main body portion 1 1 4 so as to be inserted into the positioning hole 116 formed in the lower surface of the floor panel 107 and is not high. The panel mounting portion 1 1 3 is provided on the upper surface of the main body portion 114 except for the engaging protrusion portion 1 17, and the floor panel 107 is placed and supported by placing a lower surface of the floor panel. In addition, since four pieces of the floor panel 107 are to be placed, the panel receiving member 106 forms the engaging protrusions 117 in four places. The protruding portion 1 1 5 is formed with an engaging protrusion 1 1 9 that is engaged with a hook portion 1 1 8 formed on an outer peripheral edge of the floor panel 107. The engaging protrusion 1 1 9 is formed as a ring-shaped protrusion, and is engaged with the hooking portion 1 1 8 of the floor panel 107 which is bent at the front end. The panel fixing member 1 08 is configured to fix the floor panel 1 07 to the panel pressing portion of the panel receiving member 106 by sandwiching the hooking portion 1 1 8 of the floor panel 10 with the engaging projections 1 1 9. 120, and a female screw portion 1 2 formed on an outer peripheral surface and provided on a circumferential surface of a hole portion formed at a front end portion of the panel support screw 105 in the direction of the axis, and a male screw portion 1 22 that is screwed together It is constituted by the locking screw 123. The panel pressing portion 1 20 is formed in a disc shape, so that the lower end side outer peripheral surface 12 0a is in contact with the hooking portion 1 1 8, and the hooking portion 1 is sandwiched in the up-down direction by the above-mentioned engaging protrusions 1 1 9. 1 8. The locking screw 1 23 is inserted into a hole portion 1 2 4 formed through a center portion of the panel pressing portion 1 2 0, and the male screw portion 1 22 and the peripheral surface of the hole portion formed in the panel support screw 105 are inserted. The female screw 200530472 (4) The teeth 1 2 1 are screwed together, and the panel support screw can be formed here. The base end of the locking screw 1 23 is formed with a groove for locking the panel support screw 1 20 into the panel support screw 105. 1 2 5. The fixing rod 109 is formed by a female screw 127 screwed with a male screw portion 104 formed on an outer peripheral surface of the surface, and a handle portion 129 extending from the fixed portion 127. The fixing rod 109 129 and the fixing portion 127 are crimped to the foot portion 102 at a height of the panel receiving member 106 at a certain height, so that the panel receiving member 106 cannot be rotated. In addition, the panel fixing member 108 and the fixing rod are fixed by The surface of the steel plate is formed by plating. In order to make a double floor structure, first, a floor pillar structure is arranged on the floor surface 100. The receiving member 106 causes the floor panel 107 to have a ground height? 1. The height of the panel receiving member 106 is adjusted by rotating the panel receiving member 106, and the female screw portion 103 and the male screw portion of the leg portion 102. Then, in this state, the panel receiving member is rotatable, so turning the handle portion 1 2 9 makes the lock non-rotatable. When locked, the handle portion 129 is hit by the hammer 130 until it is deformed, and the member 106 is securely locked. Silk 10 5 fits easily. The gap formed by the screwdriver can be used to turn the plate on the face to support the fixing part of the screw 1 〇 1 1 2 6 1 2 8 The upper end of the handle part is rotated to fix the temporary fixed position. Of the state. 109 is the same, it is the double structured as described above. Then, the panel support surface is rotated from 100 to a specific panel support screw 105 and 104, which can be adjusted to 106 pairs of feet. 02 Panel support member 1 0 6 1 0 Figure As shown, with. With this, the panel receives -8-200530472 (5) and, when the panel receiving member 106 becomes a specific height HI, the hooking portion 1 1 8 of the floor panel 1 7 and the engaging protrusion 1 1 9 are simultaneously engaged with each other. 'The positioning holes 1 1 6 formed on the lower surface of the floor panel 10 7 are inserted into the aforementioned engaging projections 1 1 7. In this way, the floor panel 10 7 is positioned on the panel mounting portion 1 1 3 of the panel receiving member 106 and placed. Next, the panel fixing member 108 is locked into the panel support screw 105 with a screwdriver or the like, and the panel pressing portion 120 is brought into abutment with the mounting portion 118. In this way, since the hooking portion 1 1 8 is sandwiched between the engaging protrusion portion 1 19 and the panel pressing portion 120, the floor panel 107 is fixed without causing positional deviation. By carrying out the above processes in order, a double-floor floor with underfloor space between 100 and the floor surface can be constructed. [Patent Document 1] Japanese Patent Laid-Open No. 2000- 8 75 3 7 (page 3 and 4, page 1, FIG. 2, and FIG. 9) [Patent Document 2] Japanese Patent Laid-Open No. 10-212817 Publication No. (Pages 3 and 4, Figures 1, 6, and 9) [Summary of the Invention] [Problems to be Solved by the Invention] In addition, the structure of a pillar for a double floor constructed as described above Due to the large number of parts, it takes considerable time and cost to assemble and weld each part. In addition, since each component is formed by applying electroplating to a steel sheet, an increase in cost cannot be avoided. In addition, by electroplating finishing, the generation of whiskers (true single crystals formed by low-melting-point metal plating such as s η and Zn η) or containing hexavalents-9- 200530472 (6) chromium system is difficult to avoid . Furthermore, since each component is formed by a steel plate, 'the amount of deformation in the pillar in the load resistance test of the assembled state of the panel and the pillar is large because of "the total deformation amount = the deformation amount of the floor panel + the deformation amount of the pillar". In the case of steel pillars, the total deformation tends to increase. In addition, in this double-layer floor pillar structure, 'the fixing rod 10 is used in order to prevent the panel receiving member 106 from being slack, and the fixing rod 1 009 is hit with a hammer 130 to lock it with a certain tightening torque. Therefore, when the lever is locked, a large metal rattling sound is generated, which causes noise. In addition, in the aforementioned double-layer floor pillar structure, as shown in FIG. 9, the floor panel 107 is received at a position far from the axis of the shaft pillar (from the center distance L1). Therefore, the step between the panels depends on the cement board. Bigger tendency. In addition, since the base portion 101 is riveted and fixed to the foot portion 102, it is difficult to ensure the perpendicularity of the base portion 101 and the foot portion 102. When the foot portion 102 is inclined, it becomes a step between the panels. cause. In addition, in this double-layer floor support structure, ^ is attached to the bottom part of the base] 0 1 and is fixed to the floor surface by applying an adhesive, but the adhesive enters the ring formed by the bottom of the base part 101. The thickness of the adhesive produced by the ribs 1 10 is increased. Therefore, the adhesive is originally applied thinly and uniformly, and the adhesive force is increased, but the adhesive force tends to be weak. Therefore, the effective bonding area is reduced, and the bonding area has to be increased in order to increase the bonding force. Therefore, the purpose of the present invention is to provide ... In order to reduce the number of parts, to reduce assembly work and reduce cost, and further, to withstand load work-10- 200530472 (7) the improvement of energy, no whiskers and no six Valence chrome double floor is constructed with pillars. [Means for Solving the Problem] The double-layer floor pillar structure of the present invention includes a base portion placed on the ground, and integrally erected on the base portion, and has a first screwing portion at a front end portion and an outer periphery. A pillar base having a leg portion of the second screwing portion on the surface, a panel mounting portion that engages with a hooking portion formed on the floor panel to support the floor panel, and a second screwing portion to the leg portion Screwing to freely adjust the panel receiving member of the third screwing portion with respect to the height position of the pillar base, and a panel pressing portion with the hooking portion sandwiched between the panel receiving portion and the panel mounting portion, and It is screwed with the first screwing portion, and the panel fixing member of the fourth screwing portion, which can freely adjust the height position of the panel pressing portion, and the fifth screwing with the second screwing portion of the leg portion. A fixing part of the screwing part, and a rod part integrated with the fixing part, and abutting the fixing part and the panel receiving member to fix the fixing member to the height position of the panel receiving member of the pillar base . [Effect of the Invention] According to the pillar structure for a double floor according to the present invention, the pillar base is formed by integrating a base portion and a leg portion, and a panel receiving member capable of freely adjusting the height position of the pillar base. And a panel fixing member that fixes a floor panel with a panel receiving member set at a desired height position, and fixes the position of the panel receiving member at the desired height position-11-200530472 (8) Since the component is formed by only four constituent parts, the number of parts can be greatly reduced, and the number of assembly processes can be reduced, which can reduce costs. [Embodiment] Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. [Structure of double-story floor pillar structure] FIG. 1 is a front view showing a double-story floor pillar structure of the present embodiment, and FIG. 2 is a double-story floor pillar structure of the embodiment, and (A) is a plan view. (B) is a bottom view, and FIG. 3 is a vertical cross-sectional view showing the structure of the double-layered floor pillar structure of this embodiment, and FIG. 4 is a pillar base of the double-layered floor pillar structure of this embodiment, (A ) Is a plan view, (B) is a front view, and FIG. 5 is a vertical cross-sectional view when the floor panel is supported by the double-layered floor® slab pillar of this embodiment. As shown in FIG. 1 to FIG. 3, the pillar structure for the double floor in this embodiment is composed of a pillar base 1 and a panel receiving member 2 mounted on the pillar base 1, and is supported by the panel. The member 2 is composed of a panel fixing member 3 for fixing a floor panel and a fixing member 4 for fixing a height position of the panel receiving member 2 to the pillar base 1. [Post base] As shown in Figs. 3 and 4, the post base I is composed of: a base part 6 placed on-12- 200530472 0) and a floor surface 5 and standing on this base part 6 is formed by the integrated leg portion 7. The pillar base 1 is integrally formed by die-casting with high mechanical strength. The base portion 6 is as shown in Figs. 2 (B), 3, and 4 (B), and the bottom surface 6a is formed into a square shape having a substantially flat surface so that the floor surface 5 can be firmly adhered. If the bottom surface 6a of the base portion 6 is a flat surface, since the adhesive can be made thin and uniform, the adhesion strength to the floor surface 5 can be greatly improved. On the other hand, in the conventional base portion 6 formed of a steel plate, since a ring-shaped rib is formed on the bottom surface 6a, the thickness of the adhesive is increased, and the bonding strength is reduced. The seat portion 6 becomes larger. However, in this embodiment, since sufficient joint strength can be secured with a base size smaller than the conventional size, low cost can be achieved. In order to increase the mechanical strength of the base portion 6, the thickness of the base portion 6 is gradually increased as it goes from the outer peripheral portion toward the leg portion 7. Furthermore, each ® corner portion 8 of the base portion 6 has an arcuate R shape. Therefore, even in the case of laying a floor panel, the pillar base 1 is dropped to the ground (cement board) 5 by mistake. With sufficient thickness and the R shape of the corner portion 8, the pillar base 1 can be prevented from being damaged. damage. In addition, in order to securely fix the pillar base 1 structure to the floor surface 5, a screw penetration hole 9 is formed in the base portion 6 through which a screw penetrates. The screw penetrating holes 9 are formed as circular holes in the vicinity of the corner portions 8 of the base portion 6. As shown in FIG. 3 and FIG. 4, the leg portion 7 is formed into a substantially cylindrical shape with its diameter gradually increasing toward the base portion from -13 to 200530472 (10). Department 6 stands vertically. This leg portion 7 is integrally formed with the base portion 6 by aluminum die-casting, and is not fixed by riveting or welding as is conventional. Therefore, the standing angle of the base portion 6 can be kept constant. . Thereby, it is possible to greatly reduce the step generated between the floor panels supported by the structure of the pillar base 1 of this embodiment. In addition, a hole portion 10 is formed in the leg portion 7 to insert the screwed panel fixing member 3 into the front end portion, and a female screw portion of the first screwed portion is formed on the inner peripheral surface of the hole portion 10. 1 1. In addition, a screw joint with the panel receiving member 2 is formed on the outer peripheral surface of the front end side of the leg portion 7, and the second screwing portion of the panel receiving member 2 can be freely adjusted to the pillar base 1.螺牙 部 1 2。 Screw teeth 1 2. A part of the male screw portion 12 is formed with a flat surface 1 3 by which the screw teeth are cut away. The flat surface 1 3 is formed at two opposite positions, and functions as a tool pressing portion when the post base 1 is pressed with a tool when the fixing member 4 to be described later is rotated. ® Furthermore, a plurality of reinforcing ribs 14 are formed from the leg portion 7 to the base portion 6 of the pillar base 1 here. Such ribs 14 are formed into a substantially triangular hand guard portion which is inclined toward the surface 6b of the base portion 6 from a slightly central height position of the leg portion 7, and is provided at a position where the leg portion 7 is bisected. By providing the ribs 1 4 ', the mechanical strength of the pillar base 1 can be greatly improved. As described above, in the pillar base 1 in which the base portion 6 and the leg portion 7 are integrally formed by aluminum die-casting, for example, a leg portion 7 having a diameter capable of withstanding an earthquake-resistant input acceleration of 1 G, and The thickness gradually becomes thicker and is formed by the base portion 6 which can ensure the minimum area necessary for the bonding strength. -14- 200530472 (11) Therefore, the amount of deformation of the pillar base 1 can be compared with the conventional pillar made of steel. Significantly reduced. For example, it can improve the load resistance of the panel and pillar assembly by about 30%. This makes it possible to reduce the thickness of the floor panel and reduce the weight. [Panel receiving member] As shown in FIG. 5, the panel receiving member 2 is screwed with the pillar base 1, and the height position can be adjusted freely, and the supporting floor panel 1 is placed at a specific height from the floor surface 5. The object is composed of a floor panel mounting portion 16 on which the floor panel 15 is placed, and a mounting screw portion 17 that is screwed onto the pillar base 1 integrated with the floor panel mounting portion 16. This panel receiving member 2 is the same as the pillar base 1 and is integrally formed by die-casting aluminum with high mechanical strength. As shown in FIG. 1 and FIG. 2, the floor panel mounting portion 16 is composed of a panel mounting portion 19 protruding at four places on the upper surface of the main body portion 18 and the panel mounting portions 19. In the meantime, the panel auxiliary receiving portion 20 on the upper surface of the main body portion 18 is configured. The main body portion 18 is formed as a slightly discoid body with four places as straight lines on the outer peripheral surface. The panel mounting portion 19 is formed on the upper side and the mounting screw portion 17 is formed on the lower side. The panel mounting portion 19 is provided corresponding to the outer peripheral surface of the main body portion 18 at four positions on a straight line, and is formed as a protrusion having a substantially rectangular shape. The four panel mounting portions 19 are formed by surrounding the through-hole wall portion 22 formed around the through-hole 21 formed in the center of the panel receiving member 2 so that the aforementioned feet -15-

In this way, a structure in which the floor panel 15 is mainly hung by the step portion 2 8 and placed on the panel mounting surface 23 is made, and a structure that supports the lower surface 15 a of the corner of the floor panel 15 by the panel auxiliary receiving portion 20 is made, for example, In the case of repeated walking of a trolley or the like, and a load is applied locally, the corner portion of the floor panel 15 can be prevented from being damaged. In addition, the floor panel 15 is mounted on the panel mounting surface 23 by hanging the hooking part 25 on the step part 28, and is held by the panel fixing member 3 to be described later. The fixed hand-holding structure can accelerate the construction speed of laying the floor panel 15. Conventionally, the supporting structure of the bottom surface (bottom surface) of the floor panel 15 is supported. Therefore, it is necessary to lock the fixing lever to a specific torque. In this structure, it is unnecessary. In addition, due to the supporting structure of the hand guard, the step difference between adjacent panels mounted on each panel mounting portion 19 only causes a difference in the thickness portion of the floor panel 15. In the conventional bottom receiving structure, the thickness of the entire floor panel 15 as a whole is stepped to form a bottom receiving member. In particular, the thickness of the floor panel 5 is prone to deviations. Therefore, in a conventional structure, a step is easy to produce ', but -17-200530472 (14) Yes, it is difficult to generate a step in this structure. In addition, when the plate thickness is different; ^ 3 0 0 0N panel and 5 0 0N panel are adjacent to each other, by sandwiching the space between the plate thickness difference portion between the panel mounting surface 23 and the cushion rubber 24, Simply make these panels a consistent surface. The mounting screw portion 17 is formed in a cylindrical body at the center of the lower surface of the panel receiving member 2. Here, the male screw portion 12 formed on the inner surface of the mounting screw portion 17 and the male screw portion 12 formed on the outer peripheral surface of the leg portion 7 can be screwed to freely adjust the position of the first screw position on the height of the pillar base 1. 3 screw thread part of the female screw part 3 5. By screwing the female screw portion 35 of the mounting screw portion 17 and the male screw portion 12 of the leg portion 7, the panel receiving member 2 can be adjusted to a desired height with respect to the pillar base 1. [Panel fixing member] As shown in FIGS. 1 to 5, the panel fixing member 3 is formed by holding the floor panel 15 ^ between the panel mounting portion 19 and the step portion 2 8 of the panel mounting portion 19. The panel pressing portion 29 of the portion 25 is screwed with the female screw portion 11 inserted in the hole portion 10 formed in the front end of the leg portion 7, and the fourth position of the panel pressing portion 29 can be freely adjusted. It is composed of the fixing screw 30 of the screwing part. The panel pressing portion 29 is formed as a disc body having a hooking portion pressing surface 29a at a lower end portion thereof to press the hooking portion 25 of the floor panel 15 described above. The panel pressing portion 2 9 clamps the hooking portion 25 in the vertical direction through the step portion 28 to clamp the hooking portion 25. A through hole 31 for inserting the fixing screw 30 is formed in the center of the panel pressing portion 29. -18- 200530472 (15) The set screw 3 0 is inserted into the hole portion 10 ′ formed at the front end of the leg portion 7 so that the male screw portion 32 formed on the outer peripheral surface thereof and the female screw of the hole portion 10 The teeth 11 are screwed together. For example, when the fixing screw 30 is rotated in the locking direction, the panel fixing member 3 is locked to the panel receiving member 2 side, and the hooking portion 25 mounted on the step portion 28 is clamped by the panel pressing portion 29. . Conversely, when the fixing screw 30 is turned in the loosening direction, the panel fixing member 3 rises in a direction separating from the panel receiving member 2 and releases the clamping state of the aforementioned hooking portion 25. In addition, the base end portion of the fixing screw 30 is provided with, for example, a disk-shaped screw head 34 of a cross-shaped screw turning groove 33 for locking the fixing screw 30 with a screwdriver. In this way, if the fixing screw 30 is screwed with the female screw portion 11 formed at the front end of the pillar base 1 which is integrated by die-casting aluminum, it can be firmly combined with the pillar base 1, so there is no gap. While firmly fixing the floor panel 1 5. [Fixed member] As shown in FIG. 1 and FIG. 2, the fixed member 4 is a thing that fixes the height position of the panel receiving member 2 of the pillar base 1. The male screw portion 12 is formed by the fixing portion 37 of the female screw portion 36 of the fifth screwing portion, and the rod portion 38 formed by the fixing portion 37 extending therefrom. Such a fixing member 4 makes the panel receiving member 2 into a non-rotatable locked state by contacting the lower end portion of the panel receiving member 2 which is temporarily maintained at a specific height with the rotating lever portion 38. Thereby, -19- 200530472 (16) The panel receiving member 2 can be surely maintained at a specific height position. The operation of turning the lever portion 38 of the fixing member 4 does not require a special tool, and can be simply operated with a hand (finger). Therefore, during construction, it is not necessary to hit the rod portion 38 with a hammer, so that sound can be generated and construction can be performed quietly. Therefore, it will not cause any trouble to the operators or people nearby. [Laying method of floor panel] Next, a description will be given of a construction method of laying the floor panel 15 using the double-layered floor pillar structure configured as described above. The construction process here is just one example. Regarding the steps, the order of the following processes can be changed slightly. First, the floor surface 5 having the double floor support structure configured as described above is placed. Next, 'the panel receiving member 2 is adjusted to the pillar base 1 to a specific height position. That is, by turning the panel receiving member 2 clockwise or counterclockwise, the male screw portion 12 formed on the outer peripheral surface of the leg portion 7 and the female screw portion formed on the inner surface of the mounting screw portion 17 The parts 3 and 5 are screwed together, and the height of the panel receiving member 2 with respect to the aforementioned pillar base 1 is adjusted up and down. The height position of the panel receiving member 2 with respect to the pillar base 1 is as shown in FIG. 5, and the vertical distance (height) from the floor surface 5 to the corner bottom 15 a of the floor panel 15 is set to a specific size. Once the height of the panel receiving member 2 with respect to the pillar base 1 is determined, an adhesive is applied to the bottom surface 6a of the base portion 6, and then the double-layered floor pillar structure is fixed to a specific position on the floor surface 5. Next, in order not to change the height position of the panel receiving member 2 with respect to the pillar base 1, the panel receiving member 2 is locked to be non-rotatable by the fixing member 4 and maintained at the above-mentioned special -20-200530472 (17) fixed height . That is, the operator holds the lever portion 38 of the fixing member 4 and rotates the lever portion 38 to bring the fixing portion 37 and the lower end portion of the mounting screwing portion j 7 of the panel receiving member 2 into contact. Thereby, the panel receiving member 2 is positioned and fixed to the height position of the pillar base 1 by the fixing member 4. Next, in order to fix the floor structure 5 to the floor surface 5 securely, a screw is inserted into the screw through hole 9 formed in the base portion 6 to drive the floor surface 5 into the floor. In this way, the strut structure for the double floor is securely fixed to the floor surface 5. Next, the floor panel 15 is laid on the double-layer floor pillar structure which is positioned and fixed. When laying the floor panel 15, the hooking part 25 formed at the corner portion of the floor panel j 5 is engaged with the step part 2 8 of the panel mounting part 19, and the floor panel 15 is placed on The panel receiving member 2 is on. In this way, the hooking portion 25 of the floor panel 15 and the step portion 28 of the panel mounting portion 19 are engaged, and i5a below the corner of the floor panel 15 is placed with a slight gap to the panel auxiliary receiving portion 20 and is placed. At the panel subsidy receiving section 20. ® Next “After the four floor panels 15 are placed at the four panel mounting portions 19, respectively,” the panel fixing members 3 securely fix the mounting portions 25. That is, using a screwdriver, the fixing screw 30 is locked into the female screw portion 11 of the hole portion 10 formed in the front end portion of the leg portion 7, and the hook portion pressing surface 29a formed under the panel pressing portion 29 is pressed. The hooking portion 2 5 ′ that is engaged with the step portion 28 is clamped by the step portion 28 and the panel pressing portion 29. Thereby, the floor panel 15 can be fixed to the panel receiving member 2 without a gap. -21-200530472 (18) [Effect of this embodiment] In the double-layer floor pillar structure configured as described above, the pillar base 1 in which the base portion 6 and the leg portion 7 are integrated into one, and This pillar base 1 is a panel receiving member 2 whose height can be freely adjusted, and a panel fixing member 3 which is fixed by sandwiching a floor panel 15 with this panel receiving member 2 and a panel receiving fixed at a desired height position Compared with the conventional structure, the number of parts can be reduced, and the number of assembling processes can be reduced, so that cost can be reduced. In addition, in the double-layer floor pillar structure of this embodiment, the bottom surface 6 a of the base portion 6 is formed as a slightly flat surface in close contact with the floor surface 5, so that the adhesive can be applied thinly and uniformly, which can greatly improve the floor surface. Joint strength of face 5. In addition, in the double-layered floor pillar structure of this embodiment, the base portion 6 is gradually thickened from the outer peripheral portion toward the leg portion 7, so that the strength against horizontal loads due to earthquakes and the like can be increased, and support can be improved. Mechanical strength of the pillar base 1 of the floor panel 15. In addition, in the double-layered floor pillar structure of this embodiment, the leg portion 7 is formed into a slightly cylindrical shape whose diameter is gradually increased from the front end toward the base portion 6, so that it is strong against compressive load and is not easily compressed. Furthermore, since the leg portion 7 has a hollow structure, a long adjustment amount can be secured. In addition, in the double-layer floor pillar structure of this embodiment, by forming the reinforcing ribs 4 from the leg portion 7 to the base portion 6, the mechanical strength of the pillar base 1 can be greatly improved, and the load resistance performance can be improved. . Furthermore, in addition to this -22-200530472 (19), the base portion 6 and the leg portion 7 are integrated, so that the mechanical strength of the pillar base 1 can be further improved. As a result, since the strength of the pillar base 1 is improved, it is possible to reduce the panel thickness and weight of the floor panel 15. In addition, in the double-layer floor pillar structure of this embodiment, at least the pillar base 1 and the panel receiving member 2 are formed by die-casting without the need for surface treatment and will not rust. Whiskers produced by electroplating Φ may contain hexavalent chromium. In addition, in the double-layered floor pillar structure of this embodiment, a mounting portion 2 5 of a floor panel 15 is mounted on a stepped portion 2 8 and placed on a panel mounting surface 2 3 and fixed by a panel. The panel pressing part 2 9 of the component 3 holds the hooking part 25 and fixes the supporting hand to support the structure. Therefore, it is not like the conventional structure. Poor, can reduce the step difference between panels. In addition, in the double-layer floor pillar structure of this embodiment, since the hand support structure is adopted, the horizontal distance L (referring to the figure 5 on the ground) from the axis of the pillar to the floor panel 15 can be shortened. The moment of inertia applied to the pillar base 1 is greatly reduced. Thereby, it is possible to prevent the shake suppression mechanism or the fixing mechanism of the panel receiving portion from being separately prepared. In addition, since this horizontal distance L can be shortened, the panel receiving shape can be made small and lightweight. In addition, in the double-layer floor pillar structure of this embodiment, it is not necessary to hit the fixing member 4 with a hammer, and it is possible to simply hold the lever portion 38 and rotate the fixing member 4. Therefore, the metal at the time of laying the floor panel can be eliminated. Percussion. -23- 200530472 (20) [Other Embodiments] Although the specific embodiments to which the present invention is applied have been described above, the present invention is not limited to the foregoing embodiments, and various changes are possible. For example, the procedure of laying the floor panel 15 can be changed as follows. First, an adhesive is applied to the bottom surface 6a of the base portion 6, and the floor structure 5 of this embodiment is fixed to the floor surface 5 to be installed. Next, after the adhesive is dried, the screws are inserted into the screw through holes 9 formed in the base portion 6 to securely fix the pillar base 1 to the floor surface 5. Then, after adjusting the height position of the panel receiving member 2 with respect to the pillar base 1, the lever portion 38 is rotated to position and fix the height of the panel receiving member 2. Next, the hooking part 25 of the floor panel 15 is hooked to the step part 28 of the panel mounting part 19, and the fixing screw 30 is locked to clamp the step part 28 and the panel pressing part 29. The hook portion 25 is held to support the floor panel 15. [Brief Description of the Drawings] FIG. 1 is a front view of the structure of a support for a double floor in this embodiment.
