This panel -6 - (3) 1290599 The receiving member 106 is formed by plating on the surface of the steel plate in the same manner as the previous base 1 〇 1 and the foot 1 〇2. On the upper surface of the main body portion 114, a snap-shaped projection portion 1 1 7 which is inserted into a positioning hole 116 formed in the lower surface of the floor panel 107 is inserted. The panel mounting portion 1 1 3 is provided on the upper surface of the main body portion 114 excluding the engaging projection portion 117, and the floor panel 117 is supported by placing the underside of the floor panel. Further, since four floor panels 10 7 are to be placed, the panel receiving member 106 has four of the above-described engaging projections 117. The protruding portion 115 is formed with an engaging projection portion 1 1 9 that is engaged with the hook portion 1 1 8 formed on the outer peripheral edge of the floor panel 107.

Further, each component is formed by electroplating a steel sheet, and an increase in cost cannot be avoided. Further, by electroplating finishing, the generation of whiskers (single crystals which are formed by low-melting metal plating such as Sn, Ζη, etc.) or the inclusion of hexavalent -9 - (6) 1290599 chrome are difficult to avoid. Further, in the load resistance performance test in which the slabs and the struts are assembled by the steel sheets, the amount of deformation = the amount of deformation of the floor panel + the amount of deformation of the struts, and the case of the steel struts having a large deformation amount may be completely changed. Further, in the double-layer floor pillar structure, the fixing rod 109 is used in order to prevent the member 106 from being loosened, and the metal is fixed by a certain locking torque with the iron fixing rod 109, and a large metal is generated. In the above-mentioned double-layer floor pillar structure, in the above-mentioned double-layer floor pillar structure, the position of the shaft pillar axis is away from the center (the center distance plate panel 107, the step difference between the panels depends on the cement board. It is difficult to ensure the perpendicularity of the base portion 110 and the foot portion 102 by riveting the foot portion 102 with respect to the base portion 101, and in this case, it becomes a cause of the step difference between the panels. In the pillar structure, although the lower surface is applied to the floor surface 100 by the application of an adhesive agent, the thickness of the adhesive is thickened based on the annular rib 1 formed on the lower surface of the base portion 101. Thin: Cloth, then the force will increase, but the force will be weaker and the effective area will be reduced, and the force will have to be increased in order to improve the adhesion. Therefore, the object of the present invention is to provide: reduction in assembly engineering to reduce and low Cost, enter: In the case of the part, the tilting of the shape of the strut due to "all changes causes the panel hammer 130 to strike, and the rod is locked for the cause of the rod. As shown in Fig. 9, t L1 ) tends to become larger. Therefore, the foot 102 is inclined at the base 〇1, and the concave and thinness generated by the adhesive entering the 〇 is uniformly applied. Therefore, the joint area is changed to the number of parts, and the load resistance is -10- (7) The structure of the double-layer floor pillar structure of the double-layer floor of the present invention is provided by the base structure of the double-floor floor of the present invention. And a base portion that is integrally formed at the base portion and has a first screwing portion at the front end portion, and has a leg portion of the second screwing portion on the outer peripheral surface, and a hook formed on the floor panel a panel mounting portion that supports the floor panel and a second screwing portion that is screwed to the second screwing portion of the leg portion to adjust the height of the pillar base to the third screwing portion The bearing member, and the bearing and the aforementioned panel a panel pressing portion that sandwiches the hook portion between the hook portions and a panel fixing member that is screwed to the first screw portion and that can adjust the height of the panel pressing portion to the fourth screw portion; a fixing portion of the fifth screwing portion that is screwed to the second screwing portion of the leg portion, and a rod portion that is integral with the fixing portion, and the fixing portion and the panel receiving member are in contact with each other A fixing member that fixes a height position of the panel receiving member of the pillar base. [Effect of the Invention] The pillar structure for a double-floor according to the present invention is a pillar base that integrates the base portion and the foot portion And a panel receiving member capable of freely adjusting the height position of the pillar base, and a panel fixing member fixed by sandwiching the floor panel with a panel receiving member set at a desired height position, and fixing is desired The height position of the panel is formed by only four components formed by the fixing members of the position of the -11 - (8) 1290599 pieces, and the number of parts can be greatly reduced while the number of assembly works Can be reduced, cost reduction can be achieved. [Embodiment] Hereinafter, a specific embodiment to which the present invention is applied will be described in detail with reference to the drawings. [Configuration of the double-layer floor pillar structure] Fig. 1 is a front view showing the double-floor pillar structure of the present embodiment, and Fig. 2 is a double-layer floor pillar structure according to the embodiment, and (A) is a plan view. (B) is a bottom view, FIG. 3 is a longitudinal cross-sectional view showing a double-layer floor pillar structure according to the present embodiment, and FIG. 4 is a pillar base showing a double-layer floor pillar structure according to the present embodiment. Fig. 5 is a plan view, and Fig. 5 is a longitudinal sectional view showing a floor panel supported by a double-layered floor panel according to the present embodiment. As shown in FIGS. 1 to 3, the pillar structure for a double-floor according to the present embodiment is composed of a pillar base 1 and a panel receiving member 2 attached to the pillar base 1, and is supported by the panel. The member 2 fixes the panel fixing member 3 of the floor panel and the fixing member 4 that fixes the height position of the panel receiving member 2 of the pillar base 1. [Pole base] As shown in Figs. 3 and 4, the pillar base 1 is placed on the base portion 6 of the -12-(9) 1290599 floor surface 5, and is erected on the base. The portion 6 is formed as an integral leg portion 7. The pillar base 1 is integrally formed by aluminum die casting with high mechanical strength. As shown in the second (B), third, and fourth (B) views, the base portion 6 is formed such that the bottom surface 6a has a square shape with a slightly flat surface so that the floor surface 5 can be stably adhered. If the bottom surface 6a of the base portion 6 is a flat surface, the adhesive can be made thin and uniform, and the adhesion strength to the floor surface 5 can be greatly increased. On the other hand, in the conventional base portion 6 formed of a steel sheet, since the annular rib is formed on the bottom surface 6a, the application thickness of the adhesive is increased, and the strength is lowered. Therefore, it is necessary to secure the base area. The seat 6 becomes larger. However, in the present embodiment, sufficient joint strength can be secured with a smaller base size than the conventional size, and low cost can be achieved. Further, in order to increase the mechanical strength, the base portion 6 gradually increases in thickness as it goes from the outer peripheral portion toward the leg portion 7. Further, each of the corner portions of the base portion 6 has an R shape in which the corner portion is formed in an arc shape. Therefore, even in the case of laying the floor panel, if the pillar base 1 is mistakenly dropped to the floor (cement plate) 5, the pillar base 1 can be prevented from being received by the sufficient thickness and the R shape of the corner portion 8. damage. Further, in order to securely fix the pillar base structure to the floor surface 5, a screw through hole 9 through which the screw is inserted is formed in the base portion 6. The screw through hole 9 is formed into a circular hole in the vicinity of each corner portion 8 of the base portion 6. As shown in FIGS. 3 and 4, the leg portion 7 is formed in a slightly cylindrical shape in which the diameter of the base portion 6 is gradually increased toward the base portion 6 from the front end toward the base portion 6 for the base. The 6th part is erected vertically. The leg portion 7 is integrally formed with the base portion 6 by aluminum die casting, and is not fixed by riveting or welding as in the prior art, and the erect angle of the base portion 6 can be kept constant. . Thereby, the step generated between the floor panels supported by the structure of the pillar base 1 of the present embodiment can be greatly reduced. Further, the leg portion 7 is formed with a hole portion 10 into which the screwing panel fixing member 3 is inserted at the distal end portion thereof, and the female screw portion 1 1 of the first screwing portion is formed on the inner peripheral surface of the hole portion 10 . Further, the outer peripheral surface of the front end side of the leg portion 7 is formed with a screw that is screwed to the panel receiving member 2, and the second screwing portion of the mounting height position of the panel receiving member 2 for the pillar base can be freely adjusted. The thread portion 1 2 . A portion of the male screw portion 12 is formed with a flat surface 13 which is cut away to form a flat surface. This flat surface 13 is formed in two places at the opposite positions, and acts as a tool pressing portion when the post base 1 is pressed by the tool when the fixing member 4 described later is rotated. Further, in the pillar base 1, a plurality of reinforcing ribs 14 are formed from the leg portion 7 to the base portion 6. Such a rib 14 is formed as a slightly triangular hand guard which is inclined from the slightly central height position of the leg portion 7 toward the surface 6b of the base portion 6, and is provided at a position where the leg portion 7 is equally divided. By providing the rib 14, the mechanical strength of the strut 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, the leg portion 7 having a diameter capable of withstanding the shock input acceleration of 1 G is provided, and The base portion 6 which is thicker in thickness and ensures the minimum necessary area for the strength is formed by -14-(11)(11)1290599, so that the amount of deformation of the pillar base 1 can be made by the steel plate. The pillars formed are greatly reduced. For example, it is possible to improve the load resistance performance of the panel and the pillar assembly state by about 30%. Thereby, thinning of the thickness of the floor panel becomes possible, and weight reduction can be achieved. [Panel receiving member] As shown in Fig. 5, the panel receiving member 2 is screwed to the pillar base 1, and the height position thereof can be freely adjusted, and the supporting floor panel 15 is placed at a specific height from the floor surface 5. The object is placed on the floor panel mounting portion 16 of the floor panel 15 and is screwed into the floor panel mounting portion! 6 The mounting screw portion 1 of the pillar base 1 is integrated. This panel receiving member 2 is formed in the same manner as the pillar base 1, and is integrally molded by aluminum casting with high mechanical strength. As shown in FIGS. 1 and 2, the floor panel mounting portion 16 is composed of four panel mounting portions 19 projecting from the upper surface of the main body portion 18, and the panel mounting portions 1 The panel support receiving portion 20 of the upper surface of the main body portion 18 of the nine rooms is constituted by nine. The main body portion 18 is formed as a substantially circular disk body having four straight lines on the outer peripheral surface, and the panel mounting portion 19 is formed on the upper surface side, and the mounting screw portion 17 is formed on the lower surface side. The panel mounting portion 119 is provided at a position where the outer peripheral surface of the main body portion 18 is four straight lines, and is formed into a substantially rectangular projection. Further, the four panel mounting portions 19 are formed by surrounding the annular wall portion 22 formed around the through hole 2 1 of the center of the panel receiving member 2, and the aforementioned foot -15-(12) 1290599 portion 7 Linked into one. The panel mounting portion 9 is formed to have a higher projection than the annular wall portion 22, and the upper surface of the flat surface is a panel mounting surface 23 on which a corner portion of the floor panel 15 is placed. On the panel mounting surface 23, a cushion rubber 24 having a cushioning member formed of rubber or the like is attached. The cushion rubber 24 functions as a cushioning material between the floor panel 15 and the double-layer pillar structure, and it is possible to prevent the metal from coming into contact with each other and to alleviate the reverberation sound generated when walking on the floor panel 15 The effect. Further, this cushion rubber 24 can prevent corrosion caused by the contact of the dissimilar metal of the floor panel 15 formed of the electrogalvanized steel sheet and the panel receiving member 2 formed by the aluminum die casting. Further, the inner side surface 1 9 a of the panel mounting portion 1 9 is formed in an arc shape in accordance with the shape of the corner portion of the floor panel 15 , and the panel mounting surface 23 faces the annular wall portion 22 . The inclined surface of the upper 22a is inclined. In the space portion formed by the inner side surface 19a of the panel mounting portion 19 and the upper surface 22a of the annular wall portion 22, a hook portion 25 which is formed by bending the corner portion of the floor panel 15 downward is disposed. The hooking portion 25 disposed in this space portion is engaged with the step portion 28 which is a stepped shape of the panel mounting portion 19. This step portion 28 serves as a main panel receiving portion that mounts the hook portion 25 of the floor panel 15 . Further, on the inner side surface 19a of the panel mounting portion 19, a panel positional deviation preventing projection portion 26 for preventing a positional deviation of the floor panel 15 in the horizontal direction is formed. Such a panel positional deviation preventing projection 26 is formed to be more protruded than the height of the cushion rubber 24 provided on the panel mounting surface 23, by being in contact with the hooking portion 25 of the floor panel 15. And the anti-16-(13) 1290599 stops the positional deviation of the floor panel 15. Further, on the outer surface of the panel mounting portion 19, a vertical groove 27 having a planar gate shape from the surface 23 toward the lower side to the front portion of the main body portion 18 is formed. The panel support receiving portion 20 is formed as a part of the body portion 18 in the shape of a fan in which each panel is mounted. This panel is tolerated if there is a slight gap between the lower corners of the floor panel 15 5 a 5 a (figure 5), supporting the corner of the floor panel 15 5 5 a near the final load. In this way, the floor panel 1 is placed on the panel mounting surface 23 mainly by the step portion 28, and the panel is supported by the panel 1B. When walking or the like is applied locally, the corner portion of the plate 15 can be prevented from being damaged. In addition, the floor panel 15 is attached to the panel mounting surface 23 by the hook portion 25, and is fixed by the panel fixing structure of the panel. The hand can withstand the structure, and the construction speed of the floor panel 15 can be laid. Conventionally, the bottom portion of the lower surface (bottom surface) of the support base 15 is subjected to a structure, and it is necessary to tighten the lock to a specific torque, which is not necessary in the present configuration. In addition, the thickness of the floor panel 15 is only generated in the conventional bottom receiving structure, and the thickness of the floor panel 15 is increased. The step is formed to form a bottom receiving member. In particular, the thickness of the floor panel is liable to be deviated. In the conventional structure, it is easy to cause the step placement position to be β 1 9 between the β 20 series S (refer to the bottom surface of the underside of the support vehicle, etc.; Ρ 3 The difference between the rods and the rods is fixed by the accelerator plate. The difference is 15 degrees, but -17-(14) 1290599 is that in this structure, the step is not easy to occur. In the case where the 000N panel and the 5000N panel are adjacent to each other, by sandwiching the space of the difference in thickness between the panel mounting surface 23 and the cushion rubber 24, it is possible to easily make the surfaces of the panels uniform. The joint portion 17 is formed in a cylindrical body at the center of the lower surface of the panel receiving member 2. The inner surface of the mounting screw portion 17 is formed with a male screw portion 12 formed on the outer peripheral surface of the leg portion 7, and is screwed. The female screw portion 3 of the third screwing portion of the height position of the pillar base 1 can be freely adjusted. By mounting the female screw portion 35 and the foot portion 7 of the screwing portion 17 The male screw portion 12 is screwed to adjust the panel receiving member 2 to the pillar base 1 to a desired height [Panel fixing member] As shown in Figs. 1 to 5, the panel fixing member 3 is configured to sandwich the floor panel 1 5 between the step portion 28 of the panel mounting portion 19 The panel pressing portion 29 of the joint portion 25 and the female screw portion 1 1 inserted into the hole portion 10 formed at the tip end of the leg portion 7 are screwed together, and the fourth position of the height of the panel pressing portion 29 can be freely adjusted. The panel pressing portion 29 is formed of a disk body having a hooking portion pressing surface 29a that presses the hooking portion 25 of the floor panel 15 at the lower end portion. The hook portion 25 is held by the step portion 28 in the vertical direction to sandwich the hook portion 25. Further, a through hole 3 1 for inserting the fixing screw 30 is formed at the center of the panel pressing portion 29. - (15) (15) 1290599 The fixing screw 30 is inserted into the hole 1 形成 formed at the front end of the leg portion 7, and the male screw portion 3 2 formed on the outer peripheral surface thereof and the female portion of the hole portion 10 are inserted. The threaded portion 1 1 is screwed. When the fixing screw 30 is rotated in the locking direction, the panel fixing member 3 is locked to the side of the panel receiving member 2, by means of The panel pressing portion 29 sandwiches the hook portion 25 that is carried by the step portion 28. Conversely, when the fixing screw 30 is rotated in the releasing direction, the panel fixing member 3 rises in a direction separating from the panel receiving member 2, The gripping state of the hook portion 25 is released. Further, at the base end portion of the fixing screw 3 例如, for example, a disk-shaped rotating groove 3 3 for locking the fixing screw 30 by a screw driver is provided. The screw head portion 3 is thus screwed together with the female screw portion 1 1 formed at the front end portion of the pillar base 1 which is integrally molded by aluminum die-casting, and the pillar base 1 can be coupled to the pillar base 1 With a firm fit, the floor panel 15 can be firmly fixed without a gap. [Fixed member] As shown in Figs. 1 and 2, the fixing member 4 is fixed to the height position of the panel receiving member 2 of the pillar base 1, and is formed on the outer peripheral surface of the leg portion 7. The fixing portion 37 of the female screw portion 36 of the fifth screwing portion in which the male screw portion 1 is screwed, and the rod portion 38 formed by extending the fixing portion 37 are formed. The fixing member 4 is brought into contact with the fixing portion 37 by the lower end portion of the panel receiving member 2 which is temporarily held at a specific height by the rotating lever portion 38, so that the panel receiving member 2 is in a non-rotatable locked state. Thereby, the -19-(16) 1290599 panel receiving member 2 can be surely held at a specific height position. The operation of rotating the rod portion 38 of the fixing member 4 requires no special tools and can be easily operated by hand. Therefore, it is not necessary to strike the rod portion 38 with a hammer during construction, and no sound is generated, so that it can be quietly constructed. Therefore, it will not cause problems for the operators on the spot or near the scene. [Method of Laying the Floor Panel] ® Next, a construction method of laying the floor panel 15 using the pillar structure for a double-floor structure configured as described above will be described. The construction work here is an example, and the order of the following projects can be changed a little with regard to the steps. First, the floor surface 5 is placed in a double-layered floor structure as described above. Next, the panel receiving member 2 is adjusted to the pillar base 1 to a specific height position. That is, by rotating the panel receiving member 2 in the clockwise direction or the counterclockwise direction, the male screw portion 12 formed on the outer peripheral surface of the leg portion 7 and the female thread formed on the inner surface of the mounting screw portion 17 are formed. The portion 3 5 is screwed, and the height of the panel receiving member 2 to the 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 set to a specific size from the vertical distance (height) of the floor surface 5 to the lower surface of the floor panel 15 by 15 a as shown in Fig. 5 . After the panel receiving member 2 determines the height of the pillar base 1, the adhesive is applied to the bottom surface 6a of the base portion 6, and the double-layer floor is fixed to the specific position of the floor surface 5 by the pillar structure. 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 by the fixing member 4 to be non-rotatable and maintained at the above-mentioned special height of -20-(17) 1290599. . That is, the operator holds the rod portion 3 of the fixing member 4, and rotates the rod portion 3, 8 so that the fixing portion 37 abuts against the lower end portion of the mounting screw portion 17 of the panel receiving member 2. Thereby, the panel receiving member 2 is positioned and fixed to the height position of the pillar base 1 by the fixing member 4. Then, in order to secure the fixing of the floor panel 5 to the floor surface 5, a screw is inserted into the screw through hole 9 formed in the base portion 6, and the floor surface 5 is inserted. Thus, the double-layer floor pillar structure is surely fixed to the floor surface 5. Next, the floor panel 15 is laid for the double-layer floor pillar structure that is positioned and fixed. When the floor panel 15 is laid, the hook portion 25 formed at the corner portion of the floor panel 15 is engaged with the step portion 2 of the panel mounting portion 19, and the floor panel 15 is placed on the panel.

The panel is supported by the receiving portion 20. • Next, the four floor panels 15 are placed at the four panels. After the mounting portion 19 is completed, the panel fixing member 3 securely fixes the hooking portion 25. In other words, the fixing screw 30 is locked into the female thread portion 形成 formed in the hole portion 1 of the front end portion of the leg portion 7 by a screwdriver, and the hook portion pressing surface 29a formed on the lower surface of the panel pressing portion 29 is pressed. The hook portion 25 is engaged with the step portion 28, and the hook portion 25 is sandwiched between 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 - (18) 1290599 [Effects of the present embodiment] In the double-layer floor pillar structure configured as described above, the base portion 6 and the leg portion 7 are integrally formed as a pillar base 1 and The panel receiving member 2, which can freely adjust the height of the pillar base 1, and the panel fixing member 3 fixed by sandwiching the floor panel 15 with the panel receiving member 2, and the panel fixed at a desired height position The fixing member 4 at the position of the member 2 is composed of only four constituent members.
