[The subject to be solved by the invention]

In the above patent document, the floor supported by the pedestal is set to a horizontal state by screwing the male screw and the female screw to the upper and lower position adjusting mechanism to adjust the pedestal provided on the floor and the pedestal supporting the floor. In the upper position adjustment mechanism, the thread groove of the female thread is supported by the thread of the male thread, so that the male thread and the female thread gradually rotate with each other due to the vibration applied to the support foot or the load applied to the pedestal. As a function, the upper and lower positions of the pedestal gradually deviate from the set position. Therefore, there is a problem that the level of the floor cannot be maintained after the floor is laid.

In Patent Documents 1 and 3, the lateral small screws are screwed to the level adjusting nut or the height adjusting nut, and the front end of the lateral small screw is pressed against the stay, but the lateral small screw itself is slackened by the vibration applied to the supporting leg. In the worst case, there is even a fall off. Therefore, it is difficult to solve the above problem by merely holding the lateral small screws against the pillars. In Patent Document 2, although the long nut contacts the threaded portion, the long nut is hard to rotate with respect to the screw portion due to vibration or the like applied to the support leg. It is also considered that the female screw and the male screw of the upper and lower position adjusting mechanism are fixed by the adhesive after the upper and lower positions are set. However, in the long term, it is difficult to prevent the male screw and the female screw from rotating due to the vibration applied to the support leg.

Here, the present invention provides a support leg for a floor and a setting method thereof, which can securely set the upper and lower positions. [Means for solving the problem]

The supporting leg for a floor according to the present invention comprises: a pillar which is erected on a base plate provided on the ground; an adjusting nut screwed to the pillar; and a pedestal, the upper and lower positions are set according to the upper and lower positions of the adjusting nut, and The floor supporting member is characterized in that: the deformation mechanism includes a deformation mechanism that deforms the male screw portion formed on the outer circumferential surface of the pillar to be in a state in which the adjustment nut is not rotatable. Further, the deformation mechanism is constituted by a fixing screw that is screwed to a screw hole formed in a side surface of the adjustment nut toward the support. The front end of the fixing screw abuts against the male thread portion, and the male screw portion is flattened and deformed.

According to the method for setting the support leg for a floor according to the present invention, the adjusting nut screwed to the pillar which is erected on the base plate provided on the ground is rotated, the upper and lower positions of the adjusting nut are adjusted, and the pedestal for setting the floor is set. The male screw portion formed on the outer circumferential surface of the pillar is deformed at a predetermined upper and lower position, whereby the adjustment nut is set in a state in which it cannot be rotated.

The floor supporting leg 1 comprises: a rectangular base plate 2 disposed on the floor B of the building; the pillar 3 is composed of a bolt member disposed to be disposed substantially at the center of the base plate 2; the adjusting nut 4, the screw The pedestal 5 is fixed to the upper surface of the adjusting nut 4; and the sheet-shaped cushioning member 6 is placed on the upper surface of the pedestal 5.

The adjusting nut 4 is formed as a hex nut, and has a female threaded portion having a threaded groove on the inner peripheral surface, and the pillar 3 has a male threaded portion having a thread on the outer peripheral surface. Further, since the adjustment nut 4 is screwed to the support 3, the adjustment nut 4 is rotated with respect to the support 3, whereby the adjustment nut 4 can be moved in the vertical direction together with the pedestal 5, and the upper and lower positions of the pedestal 5 can be adjusted. A circular opening is formed in the center portion of the pedestal 5 in accordance with the inner diameter of the adjusting nut 4, and the upper end of the strut 3 is inserted into or disengaged from the opening of the pedestal 5 with the movement of the adjusting nut 4 in the up-down direction.

The pedestal 5 is formed in a shape in which a circular shape is cut in a plan view of the base plate 2 in a plan view. On the inner side of the four side portions formed by the cutting, the projections are provided with alignment projections 5a which are formed in a substantially rectangular shape by being punched upward by punching. The four projections 5a are provided so as to be substantially upright with respect to the upper surface of the pedestal 5, and are set so that the longitudinal direction faces the center of the pedestal 5. Further, they are arranged at equal intervals, and are arranged equidistantly from the center of the pedestal 5, and are respectively shifted by 90 degrees one by one. Therefore, the corner portion of the rectangular floor panel F is inserted between the projections 5a, and the side portion of the floor panel F is placed along the projection 5a, and the floor panel F is placed and supported in this manner, whereby the alignment and laying can be easily performed Floor panel F. Further, since the floor panel F is placed on the pedestal 5 via the cushioning member 6 placed on the upper surface of the pedestal 5, the vibration of the floor panel F can be absorbed by the cushioning action of the cushioning member 6.

Fig. 2 is a schematic cross-sectional view showing the upper and lower directions of the support leg 1 for the floor. A screw hole 4a having a small diameter which penetrates the center axis of the support 3 is formed on the side surface of the adjusting nut 4, and a fixing screw 7 as a deformation mechanism for preventing the adjustment nut 4 from rotating is screwed into the screw hole 4a. The fixing screw 7 is formed in a hexagonal bolt shape, and the front end surface is formed in a cup shape in a concave shape, and the fixing screw 7 is screwed into the screw hole, whereby the front end surface of the fixing screw 7 abuts against the outer peripheral surface of the strut 3, and the snail of the outer peripheral surface is crushed. Part of the tooth deforms it. The thread is flattened, thereby deforming by filling the valley portion between the threads. The adjusting nut 4 is in a state in which the threaded groove portion is cut by the opening of the screw hole 4a, and a notched cross section is formed between the threaded grooves in the inner peripheral end of the screw hole 4a.

The adjusting nut 4 is screwed by the screw groove of the strut 3 being engaged by the screw groove, but in the deformed portion 3a in which the thread portion is crushed, the valley portion between the threads is filled, so The notched section of the inner peripheral end of the screw hole 4a hits both sides of the deformed portion 3a. Therefore, the nut 4 is adjusted so that the nut along the strut 3 cannot be rotated in either direction, and is set to be in a state in which it cannot be rotated.

When laying the raised floor, first, a plurality of floor supporting legs 1 are placed on the floor B at regular intervals, and the adjusting nut 4 of the floor supporting leg 1 is rotated as a reference, and the upper and lower positions of the pedestal 5 are adjusted to a leveler or the like. Set to the reference position. In addition, the reference position of the pedestal 5 of the floor supporting leg 1 as a reference is adjusted, and the upper and lower positions of the pedestal 5 of the other floor supporting leg 1 are adjusted by rotating the adjusting nut 4 by a long rod or the like. After adjusting the upper and lower positions of the pedestal 5 of the support leg 1 of the floor, the fixing screw 7 screwed to the adjusting nut 4 is screwed in, the screw of the strut 3 is partially crushed and deformed, and the adjusting screw 4 is set to be unable to rotate. State. Moreover, the base plate 2 of each floor support leg 1 is fixed to the floor B with an adhesive or the like. After the support leg 1 for the floor is fixed, the corner portion of the rectangular floor panel F is fitted between the projections 5a of the pedestal 5 of the floor support leg 1, and the floor panel F is placed and supported in this manner. In this way, the raised floor is placed between the floor B and the floor panel F to ensure space.

When the adjustment nut 4 is set to be in a state in which it cannot be rotated, even if vibration or the like is applied to the floor support leg 1 after the floor is laid, the adjustment nut 4 is not accidentally rotated, and the upper and lower positions can be surely fixed to maintain the floor. Horizontal status.

In the above example, the fixing screw 7 is screwed into the adjusting nut 4, and the distal end surface abuts against the outer peripheral surface of the strut 3, and fills the valley portion of the thread to deform it. However, as long as the member can deform the thread, it is not necessary. Use the set screw 7 and replace it with another deformation mechanism. For example, it is also possible to use a fixing screw that is formed in a push-shaped shape with a front end surface in a conical ladder shape to flatten the thread.

After the adjustment nut 4 is set to be in a state in which it cannot be rotated, the fixing screw can be removed. Therefore, a deformation mechanism such as a fixing screw can be used for the other floor support legs 1 and the adjustment nut 4 can be set to be in a state in which it cannot be rotated. Further, a through hole may be formed in the side surface of the adjusting nut 4, a dedicated tool may be inserted into the through hole, and the screw hole of the outer peripheral surface of the stay 3 may be crushed, and the adjusting nut 4 may be set in a state in which it cannot be rotated.

The floor supporting leg 10 includes: a rectangular base plate 11 disposed on the floor B of the building; and a pillar 12 formed of a bolt member disposed to be disposed substantially at the center of the base plate 11; the adjusting nut 13 and the screw The struts 15 are attached to the pillars 12 to set the upper and lower positions. The slabs 15 are fixed to the upper surface of the tubular struts 14 on the upper side of the fitting struts 12, and the sheet-shaped cushioning members 16 are placed on the upper surface of the pedestal 15.

The adjusting nut 13 is formed as a hex nut, and has a female screw portion having a threaded groove on the inner peripheral surface, and the stay 12 has a male thread portion having a thread on the outer peripheral surface. Further, since the adjusting nut 13 is screwed to the stay 12, the adjusting nut 13 is rotated with respect to the stay 12, whereby the adjusting nut 13 is moved in the vertical direction to adjust the vertical position. The tube struts 14 which are disposed substantially at the center of the lower surface of the pedestal 15 are formed in a cylindrical shape to form an inner diameter slightly larger than the outer diameter of the struts 12. Therefore, the pipe stay 14 can be inserted into the support 12 from the lower end side so as to be slidable. Moreover, the lower end of the pipe stay 14 abuts against the upper surface of the adjusting nut 13, and the pipe support 14 is also adjusted to the upper and lower positions by adjusting the upper and lower positions of the adjusting nut 13, so that the adjusting nut 13 can be adjusted by rotating the adjusting nut 13 The pedestal 15 is above and below.

The pedestal 5 is formed in a circular shape in a plan view, and the alignment protrusions 15a are formed at equal intervals on the inner side, and are disposed equidistantly from the center of the pedestal 15, and are respectively shifted by 90 degrees. The protrusion 15a is bent upward by the punching process, and is formed in a substantially rectangular shape, and is provided to protrude upward. Each of the four protrusions 15a is provided so as to be substantially upright with respect to the upper surface of the pedestal 15, and is set so that the longitudinal direction faces the center of the pedestal 15. The corner portion of the rectangular floor panel F is inserted between the protrusions 15a, and the side portion of the floor panel F is placed along the protrusion portion 15a, and the floor panel F is placed and supported in this manner, whereby the floor can be easily aligned and laid Panel F. Further, since the floor panel F is laid on the pedestal 15 via the cushioning member 16 placed on the upper surface of the pedestal 15, the vibration of the floor panel F can be absorbed by the cushioning action of the cushioning member 16.

A screw hole having a small diameter that penetrates the center axis of the support 12 is opened on the side surface of the adjustment nut 13, and a fixing screw 17 that is a deformation mechanism that prevents the adjustment nut 13 from rotating is screwed into the screw hole. The fixing screw 17 is formed in a hexagonal bolt shape, and the front end surface is formed in a cup shape in a concave shape. Similarly to the fixing screw 7, the screw hole is screwed into the screw hole, and the front end surface of the fixing screw 17 abuts against the outer peripheral surface of the stay 12, thereby being crushed. One of the threads of the outer peripheral surface of the strut 12 is deformed. The thread is crushed, whereby the valley portion between the threads is filled and deformed, and the adjustment nut 13 is set in a state in which it cannot be rotated.

A screw hole having a small diameter which penetrates the center axis of the support 12 is also formed on the lower end side of the pipe stay 14, and a fixing screw 18 similar to the fixing screw 17 is screwed to the screw hole. The fixing screw 18 is screwed into a state in which it is pressed against the outer peripheral surface of the strut 12, and the screw is crushed and pressed, whereby the fixing of the pipe stay 14 and prevention of the rotation thereof can be achieved.

In this example, the adjustment nut 13 is set in a state in which it cannot be rotated, and the tube stay 14 is fixed and prevented from rotating. Therefore, even if vibration or the like is applied to the floor support leg 10 after the floor is laid, the nut 13 is adjusted. Also, without accidental rotation, the tube stay 14 does not fall off or rotate, so that the fixed pedestal 15 can be surely positioned above and below the level to maintain the horizontal state of the floor.
