Description of the invention (1)-[Technical field to which the invention belongs] The present invention relates to the formation of double-layered floors on the foundation floor in a building. combination. [Technical Background of the Invention] A conventional computer room is provided with a double-layered floor in which a plurality of electric wires are placed in a space under the floor. The double-layered floor is formed by a plurality of horizontal logs installed on the foundation ground in the building and a floor supported by the horizontal logs. A space under the floor is divided between the basic floor and the floor and the board. Fig. 8 shows a conventional Yokogi (pedestal) 40 proposed in Japanese Patent Application Laid-Open No. 1 丨 A 2 6 4 2 3 1. The horizontal beam 40 includes a long horizontal beam main body 41 and a plurality of leg portions 42 (only one is shown in FIG. 8) connected to the horizontal beam main body 41. Each leg portion 42 is provided with a maintenance tube 42b. The grounding piece 42a is formed by a threaded shaft 42c. The maintenance cylinder 42b rotatably supports the cylinder 42c. The cylinder 42c is fixed to the holding cylinder 42b by a fixing screw 42d. The plurality of columns 42c are respectively engaged with a plurality of nuts (not shown) integrally provided on the horizontal wood body 41. The beam body 41 is supported by a receiving element 43 provided between the beam body 4 丨 and the leg portion 42. In a state in which the column μ 42c is not fixed by the fixing screw 42d, the constructor uses a screwdriver or the like to fit the screw groove 44 formed on the upper end surface of the column 42c to rotate the column 42c. As a result, the nut will move along the column 42c, and the height of the receiving element 43 and the horizontal wood body 41 from the ground level will be adjusted.

2188-4289-PF; Ahddub.ptd Page 4 509745 V. Description of the invention (2) Degree 0 However, the column 42c is fixed to the maintenance cylinder 4 2 b through the fixing screw 42d and the grounding piece 4 2 a is connected to the foundation ground In this case, the column body 4 2 c cannot be rotated, so the height of the crossbar body 41 cannot be adjusted. In addition, there are many occasions where the foundation ground is undulating. In this case, the ground piece 42a does not contact the foundation ground, and the post 42c is fixed to the ground piece 42a by the fixing screw 42d, and the post 42c and the ground piece 42a are fixed. —Rotate the body 'for height adjustment. However, due to the height adjustment of the plurality of feet 4 2, a ground plate 4 2 a is separated from the ground. Therefore, in the conventional Hengjie 40, the ground plate 42a is brought into contact with the foundation ground without fixing the column 4 2c to the ground plate 4 2a, and the position and inclination of the cross beam 41 are adjusted. After that, the post 4 2c is fixed to the holding cylinder 42b by the fixing screw 4 2c. However, the height adjustment of the 'crossbar body 41' is a waste of time due to the need for the ground plate 42a to adhere to the ground, the rotation of the cylinder using the tool, and the fixing of the cylinder 42c through the fixing screw 42d. In addition, when one column 43c is rotated to raise the horizontal wood body 41, the other columns 42c are not fixed to the maintenance tube 42b. Therefore, the horizontal shaft 41c rises with the rotation of the nut to the horizontal wood body 41. At the same time, the lower end of the cylinder 42 is separated from the bottom of the maintenance cylinder 42b. As a result, the double floor will be neither strong nor complete. In order to contact the lower end surface of the pillar 42c with Γΐ "Λ bottom wide stable double-layered flooring", it is necessary to adjust the physical and mental positions of the pillars, and the setting of the double-layered flooring is quite complicated.

The body = 2ΛHousewood combination 11 is composed of (4) feet H 5 with long horizontal beams, and the length of 设置 _ is set at equal intervals in the length direction. The main body is positioned at the position of the cardinal nut 16. It is a supporting element I. The horizontal wooden body 14 includes a pair of horizontal wooden bodies, ie, 4, and a plurality of supports that support the pair of supporting rails 1 4a. # & "b. The support rail 14a is preferably a c-shaped steel cymbal made of a metal material. The support block ΐ /! Block 14b has a pair of J formed from its τ plane and protruding in parallel. It is also formed at the branch block. There is a pillar body # # # for receiving bolts 15b. The position of the body hole 14 (1 is preferably located in the center of the support block i4b. = Block 14b is formed by a single bending of the through-hole body hole 14d and one of the branch block ⑽, and has a connecting support block 14b. The upper and lower gaps 14e. The inner diameter of the cylindrical hole i4d will change with the gap Ue. The support block 14b also has two screws formed perpendicularly to the cylindrical hole 1 4d = 14f. One screw hole 14f will communicate with the gap I4e. As shown in Figure 4, in the support block 14b, the nut 17b1 is buried in the position corresponding to the opening of the right screw hole 14f. As shown in the third tone Generally, a pair of support rails 14a are respectively supported by a pair of support bases 14c. Two screws i7al, 17a2 are respectively inserted into two screw holes I4f formed on one support rail 14a, and then arrive to form the other support rail Two screw holes 1 4 f on 14 a. One screw 1 7 a 1 may be screwed with the nut 17bl buried in the support block 14b. The other screw 17a ^ will be outside the support rail 14a provided on the other The nut 17b2 is screwed in. Therefore, a pair of support rails 14a will pass through the two screws 17al, 17a2 to And 2

509745 V. Description of the invention (6) The nuts 17bl and 17b2 are clamped and fixed on the supporting block Ub. Next, the foot 15 will be explained. Each leg portion 15 includes a grounding plate 15a, and a threaded cylinder 15b_ formed integrally with the grounding plate 15a. Each post 丨 5b is provided with a positioning helical fold 6 and a pad 丨. As shown in Fig. 2, a plurality of feet 15 are arranged along the long axis of the cross body 丨 4. In more detail, the column body 15b is arranged along the center of the crossbar body 14. As shown in Fig. 4, the leg portion 15 is mounted on the support block Ub by inserting the column 15b into the column hole 14d. The leg portion 15 is a support block 14b for supporting and fixing a pair of branches and floor anchors 14a. When the screw 1731 pairs the nut, it will shrink. The & state is called a non-reduced diameter state. In the non-reduced diameter state, although there is a predetermined friction between the column body 15b and the column hole 4d, the support block 14b can still slide along the column body 5b. Therefore, the distance between the support block 14b and the ground piece I5a can be adjusted, and the support block can be placed in a state of ΛΓ15. The predetermined friction is set according to the weight of the support block 14b "and the support rail 14a, which can prevent the value of the support block Ub. 丨 The blade of the Niu Xin brother is temporarily placed on the support block 14b and the support rail 14a. 15c will be connected with the support The building block 14b adjusts the positioning screw 6 positions in contact with this. This can determine the height of the support block " b. In addition, in the state of disposition, it is separated by two turns =: the way of the cap 16 'can change the horizontal wood body 14: ίίί: By rotating the positioning nut 16 as the 2 cap 16 rises, the crossbar body U will rise. In addition, 'make the crossbar body lower

509745

In this case, after the positioning nut 16 is lowered, the support block 4b may be pressed downward. By checking the screws 1 7 a 1 on the nuts 1 7 b 1, the gap 1 4 g will be reduced, and the inner diameter of the cylindrical hole 1 4d will be reduced. As a result, the pillar i 5b is bolted to the inner peripheral surface of the pillar hole 14d, and the relative positions of the support block 14b and the pillar 15b are restricted. In this way, the supporting blocks 14b will be positioned on the feet 15. In this embodiment, the gap 1 4 e of the positioning nut 16 and the supporting block 14 b, the screw 1 7 a 1, and the nut 17 b 1 are positioning elements. In addition, the positioning nut 16 is a supporting element that supports the horizontal wood body 14 at a predetermined height, and the screw 1 7 a 1 and the nut 1 7 b 1 are. It is a fixing element that bolts the support block 14b to the leg portion 15. Next, the floors 1 3 a and 1 3 b will be described. As shown in Fig. 1, two types of floors (the first floor 1 3 a and the second floor 1 3 b) will be supported by the cross beam group 12. The first floor 13a and the second floor 13b each have an elongated metal sheet with an i-th edge (the left end of Fig. 1) and a second edge (the right end of Fig. 1). The length of the first floor 13a is twice the length of the second floor 13b. Between the two long edges in the direction of the long axis of the flat < 1st floor 13a and the second floor 13b and the middle of the two long edges, a fitting groove inlaid with a part of the horizontal wood body 14 is formed 20. ° Below, the construction method of the double floor structure will be explained. In the initial state of the crossbar combination 11, the pillar 15b will be inserted more deeply into the pillar hole 14d. Therefore, firstly, in a non-compressed state of the column hole 14d, the column 15b is pulled downward, so that the support block 14 is separated to some extent by the ground plate 15a. As shown in Figure 5, through the pillar hole 14d and the pillar

509745 V. Description of the invention (8) Sliding friction of 1 5 b, the crossbar body 丨 4 will be temporarily arranged on the foot 丨 5. In the temporarily deployed state, the positioning nut 16 is separated from the cross-section body 14 and is disposed at the lower end of the column 15b. As shown in Fig. 1, a plurality of cross beam combinations 11 are provided on the foundation ground 2. The grounding sheet 5a is fixed to the foundation ground 2 with an adhesive or the like. The relative position of the support block 14b and the column body 15b is adjusted on the upper surface of the horizontal wooden body 14 so as to be horizontally set at a predetermined height. In more detail, change the support block l_4b to push down and push up, or position the nut 丨 6, and adjust the horizontal wooden body 丨 4 horizontally using an unillustrated level instrument. Figure 6 shows the state during the height adjustment. During the height adjustment, the grounding lugs ... are fixed on the base floor 12, so they will not be separated from the base floor 12. In addition, the column body 15b is integrally formed with the ground piece 15a so that it cannot be separated from the ground piece i5 &. Therefore, during the height adjustment, the leg portion 15 will not be in an unstable state. In the second state where the main body of the crossbar is temporarily set horizontally at a predetermined height, the four positioning nuts 16 are rotated until the four pads 丨 "make contact with Hengweiben-/ t under 1. As shown in Figure 7 As shown, through the pad 15c and the position nut 16, the crossbar body 14 will be positioned at a predetermined high yield. The post screw 17al is bolted. * This, the body 15b will be within the column hole 1 4 d梏, ± j, person ^ ^, p. Κ, 丄 L, support block 14b will be positioned more accurately on the surrounding surface. Bottom: Λ becomes the positioning of the horizontal wooden body 14. In other words, Λ ^ The position of the nut 16 is limited, and the horizontal wood body 14 is limited along the nut 17M. It is also judged that the screws, halves, and nails Hal are as shown in FIG.

509745 V. Description of the invention (9) The first and second floor boards 13a, 13b are arranged on the cross beam combination 11. The fitting grooves 20 of the respective floors 13a and 13b are fitted to the cross-wood assembly 11. In order to fix the local boards 1 3 a and 1 3 b to the horizontal wood body 11, wedges 2 2 are driven into the floor 1 3 a, 1 3 b and the horizontal wood body 11. Finally, decorative elements (not shown) are laid on the floors 13a, 13b of the plurality of brothers 1 and 2. In this way, the double-floor floor including the ground floor 1, 2, the first and second floors 1 3a, 1 3 b is completed. 'Between the ground floor 1, 2, 1 and 2 floors 1 3a, 1 3 b. Areas under the floor can be equipped with wiring such as electron microscopes and piping components such as sleeves. This embodiment has the following advantages. (1) Each foot 15 is moved by hand or by pushing the crossbar body 14 in a manner that the size of the column 15b and the hole 14d of the column are set. Therefore, the conventional operation using a screwdriver is not required, and the height of the crossbar body 14 from the base floor 12 can be easily adjusted. (2) The positioning nut 16 is screwed on the column body 15b, so the position of the positioning nut 16 can be changed by the rotation of the positioning nut 16. Therefore, it is quite easy to prevent the fall of the crossbar body 14 and the positioning of the crossbar body 14. (3) The column body 15b is integrally formed with the ground piece 15a, and the number of components is smaller than that of the conventional foot 42. Therefore, the manufacturing cost of the feet 5 is reduced. (4) The post body 15b is integrally formed with the grounding piece 15a, and it is not necessary to fix the post body 4 2c with the fixing screw 4 2 d like a conventional object. Therefore, the cross-wood assembly 11 can be quickly installed on the foundation ground 2 to improve the formation efficiency of the double floor. (5) The feet 15 are slidable with respect to the crossbar body 14. Therefore, when the sweeping wood body 14 is tilted, the ground plate i5a and the transverse wood body 14 mutually

509745 V. Description of the invention (10) Maintain to prevent the separation from the ground. In addition, the body 15b is integrally formed with the grounding piece 15a to prevent the conventional 42c from being separated from the grounding piece 42a. Therefore, the 'horizontal wood combination 11' will be stable, and the strength of the double floor will be improved. (6) The column 15b is integrally formed with the grounding piece i5a. Therefore, there is no need to return the position of the conventional cylinder 42c raised from the ground piece 42a to the original position. Therefore, the formation of the 'double floor' can be performed easily and quickly. (The sliding friction between the pillar body hole 1 4d and the pillar body 1 5b is set to a sufficient value required to temporarily arrange the horizontal wood body 14 on the foot 丨 5. Therefore, 'on the horizontal wood body Before the final positioning of 14, you can adjust the surface and horizontality of the crossbar body 14. This adjustment is easier than the conventional operation that requires the rotation of the cylinder 44 of the screwdriver 柱. (8) Through screws 17al and nut 171) 1 The way to reduce the width of the gap 14e 'the column hole 14d will be reduced, and the support block 4b will be fixed to the column 15b. Therefore, after adjusting the height of the crossbar body 丨 4, the crossbar body 14 can be positioned. In addition, the horizontal wood body 丨 4 is supported by the positioning nut 丨 6 ', so that it is possible to prevent the horizontal wood body 丨 4 from falling during positioning. Therefore, the crossbar body 14 can be easily positioned at a predetermined height. ^ (9) The supporting ore 14b has a gap 14e that can be easily formed. The slit 14e allows deformation of the support block 14b, so the inner diameter of the cylindrical hole 14d can be changed. According to the interval of the slit 14e, the movement of the support block Hb along the column 15b, the change of the movement friction, and the fixing of the support block 14b can be performed. (10) The cylindrical hole 14d is formed on the long axis of the support block 4b. Therefore, the column 15 b is arranged on the center line of the cross-wood assembly u, and the cross-wood body 14 is stably supported by the foot 15. ’,

509745 V. Description of the invention (ll) The embodiment of the present invention may also be modified as follows. The ground plate 15a and the column body 15b can be used as separate components. In more detail, the grounding piece 15a is provided with a hole through which the column body 15b can penetrate and a maintenance tube for maintaining the lower part of the body 15b. The body 1 5b is fixed to the holding cylinder and the grounding piece 15a by fixing screws. In addition, a female screw that is screwed with the column body 15b is formed at the ground piece 15a, and the ground plate 5a and the column body 5b can be connected through the female screw. In this case, because the lower end surface of the column body 15b will contact the base floor 丄 2 ', the beam body 14 will be stably supported by the leg portion 15. The support rail 14a may be adhered to the support block 141 with an adhesive). In addition, the support rail 14a and the support block 14b are made of a metal material, and the support rail 14a can also be fused to the support block 14b. In this case, screws 17al and nuts 17M need to be provided, and screws 17a2 and nuts i7b2 are not required. 'A single support pad 14a may be used instead of a pair of support pads 14a to mount them to the support block 14b. It is also possible to replace the c-shaped steel with a stell-shaped steel or a plate steel. In this case, it is preferable that the stell-shaped steel or the sheet steel is a through-hole formed by being mounted on the support block Ub and having a communication column hole 14d. The support block 14b may be formed of an elastic material. In this case, the gap 1 4 e may be omitted. Through the screws 1 7 a 1, the nuts 1 7 b 1 and 17 a 2, and the nuts 17 b 2, the supporting block 14 b will be clamped. As a result, the inner diameter of the column hole 14 d will be reduced, and the cross beam body 14 will be fixed to the foot 15. . It is possible to use a set screw which penetrates at least one support rail 14a and reaches the shaft hole 14d. In this case, the prism wood body! After the height of 4 is adjusted, the front end of the fixing screw will be in contact with the column 15b, and the fixing screw will be screwed in, and the crossbar body 14 and the foot 15 will be positioned. Therefore, the set screw 16 can be omitted. 2188-4289-PF; Ahddub.ptd p. 14

Description of the invention The screws at the front end of the cylinder body 15b contacting the cylinder hole 14d may also be omitted. Also, instead of the threaded column body 15b, a straight body having a smooth outer peripheral surface is formed on the ground piece 5a. In this case, the sliding movement of the column 15b and the supporting block 14b becomes smooth. You can also gently insert the column 15b into the column hole 14d, and the internal control of the column hole 14d is slightly larger than the diameter of the column 1 $ b. In this case, the sliding friction between the 'pillar 15b' and the bore 14d will be reduced. It is also possible to form a fitting hook at the upper part of the pillar body 15b under the fit, and a fitting hole for engaging with the aforementioned fitting hook is formed at the lower part of the inner peripheral surface of the pillar hole " d. In this case, when the ground piece 5a leaves the ground 12, the leg portion 15 lowers the support block 14b by the weight of the leg portion 15a. In addition, since the fitting hooks of the column body 15b are fitted into the fitting holes of the support block 14b, the leg portion 15 is not removed from the support block 14b. For example, 'the height and level of the cross-wood body 14 are adjusted in a state where the two foot portions 15 provided at both ends of the cross-wood body 14 are engaged with or disengaged from the base floor 12. When the foundation ground 2 is undulating, the two feet 15 provided in the middle of the cross-section body 1 4 will drop due to their own weight, and the ground piece i5a will contact the foundation ground 12. Therefore, it is possible to perform positioning of the two middle feet 5 according to the cross-body 14 that is subject to position adjustment. The feet 丨 5 move by their own weight, so the height adjustment of the crossbar body 丨 4 becomes easy. In the case where the sliding friction between the column 15b and the support block 14b is increased, a groove may be formed on the inner peripheral surface of the column hole 14d, and a 0-shaped rubber ring system may be embedded in the groove. Alternatively, the inner peripheral surface of the cylindrical hole 14d may be covered with a material that is not easily slid like rubber.

2188-4289.PF; Ahddub.ptd jvj ^ 745 V. Description of the invention (13) It is also possible to replace the cylindrical body 15b with a thread, and form a circular cylindrical body with a T-slip outer peripheral surface on the ground piece 15a. The post is embedded in 70 pieces of support with annular flanges. In this case, the beam body 14 is supported by the flange of the support member. After the height of the crossbar body 14 is adjusted, the support member is used to fix several pieces to the column body to limit the lowering of the crossbar body 14. In this case, the positioning nut 16 can be omitted. A clamp for holding a circular column can also be set on the circular column. The fall of the crossbar body 14 is restricted by the loss of clamp. After pulling all the feet 15 out of the branch block 14b, the height of the f wooden body 14 may not be adjusted. In more detail, first, the two foot portions 15 provided at both ends of the cross-wood body 14 are joined by the ground piece 12 of the support block Ub. Next, adjust the height and level of the horizontal wooden body 丨 4 manually or by using a bit nut 16 connected to the ground. Let the feet 15 drop down to ground the piece! 5 The two positioning nuts 16 connected to the foundation ground may support the crossbar body 14 as well. Correlation In this case, since there is no need for the conventional operation of lowering the pillar 仏 at the bottom of the base piece 42a, it is easy to perform the configuration of ί, ′:. Also, the 2 central feet 15 are not required to be higher than the required height, so they will not make a seat. * The birth ward a is more deformed than the two ends: when the center of the branch rail 148 occurs, it will happen that The rotation of the snail screw raises the horizontal wood body 14. "Bagan's implementation of the tragedy" will move the foot 15 to the horizontal wooden body 14 ^ After the "main body" protrudes, adjust the horizontal wooden body "to face 12 ... but not all the foot 15 from the supporting block " b lead: face
