Description

[Detailed description of the invention] The present invention relates to an underfloor support device that is useful for so-called dumping construction, and in particular, when adjusting the installation height of the floorboard, the operator can operate it from above the floorboard after it has been laid. In addition to making it extremely easy and smooth to carry out the work, when the work is completed, the floorboards can always be fixed and supported in a stable manner against external forces acting from any direction, and vibrations and unpleasant noises can be directly transmitted from upstairs to downstairs. This has been improved to prevent it from spreading.

4 Below, the specific structure of the present invention will be explained based on the illustrated embodiment. In FIGS. 1 to 3, 1 is a floor plate, on which an overlay material such as tatami mats or carpets may be laid.

Reference numeral 2 denotes an operating port formed through the predetermined position, and this may be opened at an interconnection point with an adjacent floor plate 1.

Reference numeral 3 designates an inverted high-, T-shaped catch seat that is fixed to the floor plate 1 from below so as to face directly below the operation port 2, and a circular overhang that is seated on the underside of the floor plate 1 is attached to the upper part of the seat. Tsuba 4 is connected.

In addition, this catch seat 3 can be provided with a window opening on its circumferential surface and a plurality of reinforcing ribs. It's okay.

Reference numeral 5 designates a centering guide plate inserted between the protruding flange 4 of the catch seat 3 and the floor plate 1, and in the figure, the guide plate 5 is a ring-shaped paper coated with adhesive on one side in advance. After peeling off the release paper, the center opening of the ring-shaped paper is correctly aligned with the operation port 2 of the floorboard 1, and the paper is pasted to the bottom surface of the floorboard 1 with adhesive. There is.

The protruding flange 4 of the catch seat 3 has the same circular shape as the ring-shaped paper, so that as long as the flange 4 is aligned with the paper that is attached to the floorboard 1 first, the flange 4 will automatically fit. The catch seat 3 and the operating port 2 can be correctly aligned.

Therefore, as long as such a guiding function is to be performed, the centering guide plate 5 may be made of not only the above-mentioned paper but also a metal plate with protrusions formed by burring, and the protrusions are inserted into the operation port 2 of the floor plate 1. By inserting and engaging correctly,
It may also be used as a guide for centering the seat 3 to be seated later and the operation port 2.

Reference numeral 6 denotes a screw support installed loosely in the center of the bottom wall of the catch seat 3, and a locking groove 7 is formed at its upper end, while a stable seat 6 is connected to the floor slab 8 at its lower end. It is designed to be removably screwed onto the stand 9.

The stable seat 9 is a plate-shaped body, and includes a metal plate 11 with a threaded cylinder 10 protruding downward (inward) by burring, a thick rubber integrally formed on the bottom surface of the metal plate 11, and other preventive materials. It is cut out from the contact seat 12 of the vibration material, and its seizure is sometimes done to prevent rubber from flowing into the threaded cylinder 10.

A U-shaped pot protection cover 13 is also buried.

The lower end of the screw support 6 is screwed into the screw cylinder 10 of the thick plate-like seat 9, and is assembled into one piece with a lock nut 14. The contact seat 12 of the vibration material contacts.

Therefore, when this invention is used in a multi-story or double-floor building,
In addition to suppressing the sound and vibrations of footsteps on the floor from directly propagating to the downstairs, its elasticity also allows it to absorb the non-smoothness of the surface of the floor slab 8.

Further, 15 is a leveler that supports the center of the bottom wall of the catch seat 3 from below, and includes a hexagonal nut 16 screwed into the middle of the screw support 6, and a horizontal circular collar that is integrally fitted with the hexagonal nut 16. Cut from board 17.

Reference numeral 18 designates a cuff washer inserted between the contact surfaces of the flange plate 17 and the catch seat 3 of the leveler 15, and a plurality of hemispherical protrusions 19 that make point contact with the flange plate 17. are integrally installed in a dotted manner.

Therefore, the load of the worker standing on the floor plate 1 is
5 and the catch seat 3, the sliding rotation of the leveler 15 with respect to the fixed-side catch seat 3 is possible without generating excessive frictional force. Rotation operations can be performed easily and smoothly.

Reference numeral 20 denotes a presser cap loosely fitted to the screw support 6 from above the catch seat 3, and facing the bottom wall of the catch seat 3 together with the leveler 15 and washer 18.

This cap 20 is the nut 1 in the leveler 15.
It is always engaged with the outer circumferential surface of the threaded support 6 in a crown-like manner, thereby integrally rotating the leveler 15, and the leveler 15 is moved up and down along the threaded support 6.

Therefore, as long as this function can be performed, the cap 20 and the leveler 15 are not limited to the hexagonal nut shape as shown in the figure.

Furthermore, 21 is a lock nut screwed onto the screw post 6 from above the presser cap 20, and this lock nut has an outer diameter D2 smaller than the outer diameter D□ of the cap 20, thereby preventing the rotation of the cap 20. Locknut 2 during operation
1 is not allowed to go around with them.

Note that 22 is a plurality of fixing tools for fixing the catch seat 3 to the floorboard 1.

In the above configuration, when performing underfloor construction, the floor plate 1 is laid with the seat 3 correctly fixed directly below the operation port 2, while the stable seat 9 is resiliently grounded on the floor slab 8. On the other hand, the screw support 6 is assembled in one piece.

In the laid state, a worker stands on the floorboard 1, inserts a box wrench or other rotary tools T into the seat 3 through the operation port 2 of the floorboard 1, and rotates the leveler with the tools T. The presser cap 20 is rotated.

Then, since the leveler 15 also rotates together with the cap 20, the catch seat 3 supported from below by the leveler 15 moves up and down along the screw support 6.

Therefore, after checking the desired installation height of the floorboard 1 through this operation, if you tighten the lock nut 21 with a rotary tool inserted separately from the operation port 2, the installation height of the floorboard will be completely fixed. , the floor board 1 is now in a safe and level installation state.

□In this case, since the above-mentioned work is performed from above the floorboard 1, the load of the worker acts on the contact surfaces of the catch plate 3 and the collar plate 17 of the leveler 15, so that they come into full contact with each other. A reinforcing washer 18 is inserted between the reinforcing washers 18, and is defined by a plurality of scattered hemispherical protrusions 19 to make point contact with the leveler 15 on the rotating side. Since there is a leveler 15 using the presser cap 20
The rotation of the floor plate is carried out very smoothly with little friction with the seat 3 on the fixed side, and the adjustment operation of the installation height of the floorboard can be performed very easily.

Due to the insertion and installation of the reinforcing washer 18, the contact portion between the catch seat 3 and the leveler 15 is superimposed and strengthened due to the assembly structure.
The screwing and rotating posture of No. 5 is also constantly corrected and kept stable.

As described above, in the present invention, the assembly is integrated with the seat 3 that is fixed from below to the floor plate 1 having the operation port 2, and the stable seat 9 that is grounded to the floor slab 8, and the center of the seat 3 A leveler 15 is threaded in the middle of the screw support 6 to support the catch seat 3 from below, and a leveler 15 is screwed into the support support 6 from above the catch seat 3. and leveler 15
The presser cap 20 constantly engages and rotates the presser cap 20, and the operator stands on the floorboard 1 and presses the operation port 2.
The installed height of the floor plate 1 is adjusted by rotating the leveler 15 integrally with the presser cap 20 using a rotary tool T inserted from the top, through the lifting and lowering action of the catch 3 along the screw support 6. This is because the reinforcing washer 18 is interposed between the leveler 15 and the catch seat 3, in which a plurality of hemispherical protrusions 19 are integrally projected in a dotted manner and are in point contact with the surface of the leveler 15. , it is possible to suppress the excessive friction that occurs between the mutual contact surfaces of the fixed side seat 3 and the rotating side leveler 15, and even if the load of the worker acts on the floor plate 1 during that time, it will not be affected by this. Place the leveler 15 on the catch plate 3.
′, rotation work can be performed smoothly and easily, and the desired optimal adjustment state of the floorboard installation height can be obtained with high efficiency.

In this regard, in an assembly configuration in which the stationary side seat 3 and the rotary side leveler 15 are in full contact with each other and are in close contact with each other, the worker can rotate the leveler 15 while remaining on the floorboard 1 after installation. Due to the fact that the leveler 15 is operated in such a way that the load acts directly between the contact points, it is actually extremely difficult to rotate the leveler 15.

In particular, when it is desired to raise the installation height of the floorboard 1, it is impossible to rotate the leveler 15.

Moreover, the catch seat 3 covered with the above-mentioned synthetic resin decorative sheet
When the leveler 15 is brought into support contact from below,
The metal surface of the leveler 15 comes into close contact with the film quality of the sheet, making it impossible to rotate the leveler 15.

According to the present invention, such problems can be completely solved despite the extremely simple configuration.

In addition, the seat 3 that supports the floorboard 1 has an inverted bat shape as a whole, and is seated on the floorboard 1 by its circular protruding collar 4, so that it can withstand external forces acting from any direction.
The floorboard 1 can be stably fixed and supported, and there is no fear that it will tilt due to eccentric loads.

In this respect, in a catch seat that is not provided with a continuous annular circular overhanging collar 4 and has a U-shaped cross section, the greater the height or depth, the less stable it becomes and the more likely it is to tilt. floorboard 1
It is difficult to support the retainer cap 20 and the lock nut 21 with an even force, and since the retainer cap 20 and the lock nut 21 cannot be completely surrounded by the catch seat 3, there are many chances of rotation failure due to foreign objects.

Such problems can also be prevented by the configuration of the present invention, and the catch seat 3 can also be made thinner.

Furthermore, the stable seat 9 is made of vibration-proof material such as thick rubber,
As a result, it is elastically grounded to the floor slab 8, so it can absorb the unevenness of the surface of the floor slab 8, and the floor plate 1 can be easily leveled as a whole without being affected by the unevenness. At the same time, its elasticity also suppresses vibrations and unpleasant noises that spread directly from upstairs to downstairs.
It can be said that this is an effective underfloor support device especially for use in construction of temporary flooring for multi-story or double-floor buildings.
