Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor board supporting device used for laying floor boards such as tatami mats, carpets, cushion floors, and wooden floors on a floor surface of a concrete floor slab in a building with good horizontality. Regarding

[0002]

2. Description of the Related Art As a floor plate supporting device of this type, conventionally, as shown in FIG.
01) a height adjusting bolt (102) is rotatably erected on the female screw member (1) screwed to the bolt (102).
In (03), a square floorboard receiving member (104) is integrally provided. The floor board receiving member (1
An adhesive sheet (105) is provided on the upper surface of 04).

A floorboard laying operation using the floorboard supporting device (100) is performed as follows. That is, a plurality of floor panel supporting devices (100) are used to support a plurality of base panels (B) at a predetermined height position above the floor slab (A). At this time, the support of the base panel (B) by each floor board supporting device (100) is performed at the peripheral edge of the panel (B), and a predetermined gap (107) is opened between the base panels (B). As a result, the top surface of the height adjusting bolt (102) of the floor board supporting device (100) is exposed to the outside through the gap (107). Next, the height adjusting bolts (10) of each supporting device (100) are
By adjusting the rotation of 2), the base panel (B)
After adjusting the height of the base panel so that it will be in a horizontal state, an adhesive is applied to the top of the bolt (102) so as not to cause misalignment due to unintentional rotation of the height adjusting bolt (102). It is injected from the gap (107) between B), and the bolt (102) and the female screw member (103) are fixed with an adhesive. Next, the laminating board (C) is placed on the base panel (B), and the floor finishing material (D) such as a flooring board is further placed on the laminating board (C) to complete the laying work.

By the way, when laying the floor board, a large number of the floor board supporting devices (100) are used, and an adhesive is injected into all of the supporting devices (100) to adjust the height of the bolt. It is necessary to fix (102) and the female screw member (103). That is, when the adhesive is not inadvertently injected into any of the supporting devices, the bolts (10
The undesired rotation of 2) causes a height adjustment error, which causes a problem in the laid condition of the floorboard. Specifically, problems such as floating or sinking of the floor plate and floor squeaking during walking occur. Such a problem can be solved by reliably injecting the adhesive into each supporting device (100), but on the other hand, it is practically not guaranteed at the laying construction site. It is difficult, and in reality, it is necessary to prepare specific countermeasures for such situations.

Conventionally, in the case where a failure occurs in the laying condition of the floor board due to forgetting to inject the adhesive or the like, the following measures have been taken.

That is, since the repair operation cannot be performed from the front side (floor board upper surface side) after laying the floor board, enter the underfloor space between the floor board and the floor slab (A), and as shown in FIG. , Forgot to inject adhesive, bolt (10
2) and the female screw member (103) are not adhered and fixed to both sides of the floor board supporting device (100a), the device (10
0a) has a new floor board support device (11
0) (110) is arranged and fixed in the same manner to support the relevant portion of the floor plate. Incidentally, the bolt (102) and the female screw member (1) in the new floor board supporting device (110).
By applying adhesive in advance to the threaded portion between 03),
The floor board can be supported by the floor board supporting devices (110) and (110) to which the bolts (102) and the female screw member (103) are adhesively fixed. As described above, the floor board supporting device (100
4 base panels (B) and (B) supported by a)
(B) (B) is a new floor board support device (110) (11
Since it is supported by using 0), it is possible to solve problems such as floating and sinking of the floor board and floor squeal.

Alternatively, when the male screw portion of the height adjusting bolt (102) is exposed in the underfloor space and there is room for screwing the height adjusting bolt (102) upward, In some cases, countermeasures such as That is, the worker enters the underfloor space between the floor plate and the floor slab (A) and adheres to the outer peripheral surface of the male screw portion of the bolt (102) exposed in the underfloor space, as shown in FIG. Agent (1
20), the height adjusting bolt (102) is screwed and moved upward as shown in FIG. 10 (b) to move the adhesive to the inside of the female screw portion of the female screw member (103). It is transferred to the peripheral surface, and then, as shown in FIG. 10C, the height adjusting bolt (102) is moved downward by a screwing operation to bring the floor-contacting base material (101) into contact with the floor slab (A). Let it adhere and fix it. When the transfer of the adhesive is insufficient, the adhesive is applied again to the outer peripheral surface of the male screw portion of the height adjusting bolt (102), and then the bolt (1
02) is screwed up and down one more time to transfer the adhesive sufficiently, and then the floor slab (A)
Fixed to. According to this method, the adhesive can be applied to the threaded portion between the bolt (102) and the female screw member (103), so that the bolt (102) and the female screw member (103) can be adhesively fixed, and the floor plate It can solve problems such as ups and downs, and ringing of the floor.

[0008]

However, the above conventional method has the following problems. That is, in the case of supporting using the former new floor board supporting device, it is necessary to perform the above-mentioned series of arrangement work, which is very time-consuming, and a new supporting device is required, resulting in a significant increase in cost. There was also the problem of doing.

Although the latter method has the advantage that it is relatively labor-intensive compared to the former method, the premise is that the male screw portion of the height adjusting bolt is exposed in the underfloor space, and The condition that the bolt can be screwed upward must be met, which is not a method that can handle any case and has a problem of poor versatility. Further, in order to sufficiently transfer the adhesive agent, it is often necessary to repeatedly perform the vertical screwing movement operation of the height adjusting bolt, and in such a case, the operation becomes complicated. Furthermore, since the adhesive is supplied to the gap (screw space) between the male screw portion of the height adjusting bolt and the female screw portion of the female screw member by transfer, the adhesive agent is sufficiently supplied to the screw space. It cannot be filled, and therefore it is not possible to secure sufficiently excellent properties in terms of adhesive strength.

The present invention has been made in view of such a technical background, and even if the screwing portion is not adhered and fixed unintentionally by forgetting to inject the adhesive, the floor board is laid. A floorboard that can easily supply the adhesive to the screwed portion afterwards in a short time and at low cost, and can also secure excellent performance as the strength of adhesive fixing of the screwed portion afterwards. It is intended to provide a support device.

[0011]

The above object is to provide a floor-contacting base material, a height adjusting bolt rotatably erected on the floor-contacting base material, and a female screw member screwed to the bolt. In a floorboard support member integrally formed with the female screw member or a floorboard supporting device including the floorboard, an adhesive agent reservoir is provided on an upper portion of the female screw member, and at least one adhesive injection hole is provided in a peripheral wall of the female screw member. This is achieved by the floor board supporting device (first invention), which is individually formed and the adhesive injection hole communicates with the adhesive reservoir.

Since the adhesive injection hole is provided in the peripheral wall of the female screw member and the adhesive injection hole is communicated with the adhesive reservoir, the adhesive injected from the adhesive injection hole is not retained in the adhesive reservoir. The adhesive stays in the portion and enters the gap (screw space) between the male screw portion of the height adjusting bolt and the female screw portion of the female screw member in order due to its own weight. The joint part can be fixed by adhesion. Therefore, even if unintentionally forgetting to inject the adhesive and the screwing part was not fixed by adhesion, the operator simply enters the underfloor space and injects the adhesive from the adhesive injection hole to perform the subsequent screwing. Since the adhesive fixing of the parts can be completed, the work can be facilitated, and the work time can be extremely shortened, and the cost can be reduced. Further, the adhesive is not supplied to the screwing space by transfer, but the adhesive is supplied to the screwing space by its own weight drop of the adhesive staying in the adhesive reservoir, so that the adhesive is adhered to the screwing space. The agent is sufficiently supplied, and excellent adhesive fixing strength can be obtained in the screwed portion, whereby the floor plate can be secured without feeling of floating or sinking and floor squeaking.

In the floor board supporting apparatus of the first aspect of the present invention, the expanding portion is provided at the upper portion of the female screw member, and the adhesive reservoir is formed between the expanding portion and the height adjusting bolt. It is preferable to adopt the configuration. Adopting such a structure ensures that the adhesive is supplied from the adhesive reservoir to the screw space. That is, since the adhesive is more sufficiently filled in the screwing space, the adhesive fixing strength can be further improved.

An adhesive guide groove, which is continuous in the vertical direction and has an upper end communicating with the adhesive reservoir, is formed on at least one of the outer surface of the height adjusting bolt and the inner surface of the female thread of the female thread member. It is preferable to adopt the formed structure. Since the adhesive guide groove is formed in the adhesive reservoir in a communicating state, the adhesive that has accumulated in the adhesive reservoir is mainly efficiently supplied to the screw space through the adhesive guide groove. The screwing space is filled with the adhesive agent more sufficiently, whereby the adhesive fixing strength can be further improved.

It is preferable that the lower end of the adhesive guide groove is disposed above the lower end position of the screw portion provided with the adhesive guide groove. If such a configuration is adopted, the adhesive that has descended through the adhesive guide groove is effectively prevented from moving below the lower end of the adhesive guide groove (that is, the lower end of the screw portion). Therefore, the adhesive can be prevented from flowing out of the screwing space, whereby the adhesive can be more sufficiently filled in the screwing space, and the amount of the adhesive used can be reduced.

[0016] Further, the above object is to provide a floor contact base material, a height adjusting bolt rotatably erected on the floor contact base material, a female screw member screwed to the bolt, and a female screw member. In a floor plate supporting member integrally provided or a floor plate supporting device comprising a floor plate, an adhesive guide groove that is continuous in the vertical direction is formed on the inner surface of the female screw portion of the female screw member, and an adhesive is formed on the peripheral wall of the female screw member. At least one injection hole is formed, and the adhesive injection hole is made to communicate with the adhesive guide groove. This is also achieved by a floor board supporting device (second invention).

Since an adhesive injection hole is provided in the peripheral wall of the female screw member and the adhesive injection hole is communicated with the adhesive guide groove, the adhesive injected from the adhesive injection hole is mainly used. By its own weight, it enters the screwing space through the adhesive guide groove, and the screwed part can be adhesively fixed by the entered adhesive. Therefore, even if unintentionally forgetting to inject the adhesive and the screwing part was not fixed by adhesion, the operator simply enters the underfloor space and injects the adhesive from the adhesive injection hole to perform the subsequent screwing. Since the adhesive fixing of the parts can be completed, the work can be facilitated, and the work time can be extremely shortened, and the cost can be reduced. Furthermore, the adhesive is not supplied to the screwing space by transfer, but the adhesive is mainly supplied to the screwing space by its own weight drop through the adhesive guiding groove of the adhesive. Adhesive is sufficiently supplied to the base plate, and excellent adhesive fixing strength can be obtained in the screwed portion, whereby a feeling of floating / sinking of the floor plate and floor squeal can be secured.

In the second aspect of the invention, it is preferable that the lower end of the adhesive guide groove is disposed above the lower end position of the female screw portion. If such a configuration is adopted, the lowering of the adhesive agent that has descended through the adhesive agent guiding groove (that is, the lower end portion of the female screw portion) is effectively prevented from moving below this. Therefore, the adhesive can be prevented from flowing out of the screwing space, whereby the adhesive can be more sufficiently filled in the screwing space, and the amount of the adhesive used can be reduced.

The part (3a) is screwed. The upper end portion connected to the female screw portion (4a) is enlarged in diameter to form an enlarged portion (4b) whose inner diameter is larger than that of the adjusting bolt (3). An adhesive reservoir (10) is formed between the bolt and the bolt (3). Then, as described above, the adhesive reservoir (10) has the adhesive guiding groove (1).
It communicates with 2).

Further, the expanding portion (4) of the female screw member (4) is
An adhesive injection hole (11) is provided in b), and the adhesive injection hole (11) communicates with the adhesive reservoir (10).

The floor plate receiving member (5) has a through hole (5a) for attachment in the central portion and has an adhesive sheet (2) on the upper surface.

The floor board receiving member (5) is integrally attached to the female screw member (4).

The floor board laying work using the floor board supporting device (1) is performed, for example, as follows. That is, a plurality of floor board supporting devices (1) in which the height position of the floor board receiving member (5) is roughly adjusted are prepared. By using these floor board supporting devices (1), a plurality of base panels (B) made of particle board or the like (for example, a width and a length of 450) are used.
mm or width 450 mm, length 900 mm, thickness 20 mm, etc.) is supported at a predetermined height position above the floor slab (A). At this time, as shown in FIG. 7, the base panel (B) is supported by each floor board supporting device (1) at the peripheral edge of the base panel (B), and a predetermined gap is provided between the base panels (B). To open. In this supporting state, the height adjusting bolt (3) is rotated to adjust the height of the floor plate receiving member (5) so that the base panel (B) is in a horizontal state, and the floor contacting base material (2) is adjusted. ) To the floor slab (A).

Next, after fixing the base panel (B) and the floor plate receiving member (5) by nailing (not shown), as shown in FIG. 1, the adhesive reservoir ((1)) of each floor plate supporting device (1). A predetermined amount of adhesive (20) is injected into 10). As a result, the adhesive (20) flows downward through the adhesive guide groove (12) and is also filled in each thread trough. As a result, the height adjusting bolt (3) and the female screw member (4) are firmly bonded and fixed. Next, the disposing laminating board (C) is arranged on the base panel (B), and the floor finishing material (D) such as a flooring is arranged on the disposing laminating board (C) to complete the laying work of the floor board.

The above-mentioned laying mode shows an example thereof, and is not particularly limited to such a configuration. For example, the floor finishing material (D) may be arranged directly on the base panel (B) without using the discarding laminated board (C). Or, a laminated plywood (C) and floor finishing material (D)
A floor heating panel may be interposed between them, or a floor heating panel may be arranged in place of the discarding laminated board (C).

The laying work is completed as described above. However, due to the large number of floor board supporting devices (1) used in the laying work and the like, unintentionally forgetting to inject the adhesive causes screwing. There may be a floor board supporting device (1) in which the joint portion is not adhesively fixed. In such a case, the height adjustment may be misaligned due to the unintentional rotation of the bolts caused by vibrations such as walking after laying the floorboard, causing the floorboard to float or sink, or to ring during walking. It is easy to cause problems such as In the present invention, since the adhesive injection hole (11) is provided in the peripheral wall of the female screw member (4) and the adhesive injection hole (11) communicates with the adhesive reservoir (10), Adhesive such as (2
Even if the injection of 0) is forgotten, the subsequent adhesive fixing work of the screwed portion can be performed very easily and in a short time.

That is, when it is necessary to repair after the laying work is completed due to forgetting to inject the adhesive, the laying state of the floor board is left as it is, and the worker enters the underfloor space and first, the floor board supporting device (1). ), And then inject the adhesive (20) through the adhesive injection hole (11) provided in the female screw member (4). The adhesive agent (20) injected from the adhesive agent injection hole (11) stays in the adhesive agent reservoir (10), and due to its own weight, the male screw portion (3a) and the female screw of the height adjusting bolt (3) are successively inserted. Material (4)
Of the female screw portion (4a) into the gap (screw space), whereby the screw portion, that is, the bolt (3) and the female screw member (4) can be adhesively fixed. In this manner, the worker can enter the underfloor space and inject the adhesive (20) through the adhesive injection hole (11) to complete the subsequent adhesive fixing of the screwed portion.

In particular, in the above embodiment, the adhesive reservoir (1) is formed on the outer surface of the male screw portion (3a) of the height adjusting bolt (3).
0) is formed with an adhesive guiding groove (12), whereby the adhesive (20) is supplied to the screwing space more efficiently, and the adhesive (20) is sufficiently supplied to the screwing space. Therefore, there is an advantage that the adhesive fixing strength between the bolt (3) and the female screw member (4) can be further improved.

Before the height adjusting operation of the floor board supporting device (1), if necessary, based on the result of the investigation of the adhesive fixing state of the floor-contacting base material (2) and the floor slab (A). It is also possible to carry out a bonding operation with an adhesive between them.

Examples of the above-mentioned adhesive (20) include room-temperature curing type adhesives and synthetic resins, and of these, one-component type is preferably used. In addition, the injection amount of the adhesive (20) is preferably set to an amount that can sufficiently fill the screwing space and fill the space. This makes it possible to secure a sufficient adhesive fixing strength.

In the floor board supporting device (1) of the first invention, the number of the adhesive injection holes (11) provided in the peripheral wall of the female screw member (4) is not particularly limited, and is the same as in the above embodiment. The number may be one, two may be provided as shown in FIG. 3, or three or more may be provided.

Alternatively, it may be formed on the inner surface of the female screw portion (4a) of the female screw member (4). Alternatively, it may be formed on both the outer surface of the male screw portion (3a) and the inner surface of the female screw portion (4a).
Moreover, the number of the adhesive guide grooves (12) is not particularly limited.

In the embodiment shown in FIG. 3, the lower end position (Q) of the adhesive guiding groove (12) provided on the inner surface of the female screw part (4a) is the lower end position (R) of the female screw part (4a). Since it is arranged so as to be higher than the above, the adhesive that has descended through the adhesive guide groove (12) is transferred to the female screw portion (4a).
The lower end position (Q) of the guide groove (12) is blocked by the lower end of the guide groove (12).
It is prevented from moving downward and flowing out of the screwing space.

It is preferable that the adhesive guide groove (12) is continuously extended in the vertical direction because the adhesive can be supplied to the screwing space more efficiently. It is needless to say that the “vertical direction” mentioned here includes the axial direction of the bolt (3) or the female screw member (4), but other vertical directions slightly inclined with respect to the axial direction and large inclinations. It also includes a spiral vertical direction.

In addition, in the floor plate supporting device of FIGS. 1 and 3, the expanding portion (4b) is provided on the upper part of the female screw member (4) to form the adhesive reservoir (10). The adhesive reservoir (10) is not particularly limited to the one having such a structure. For example, as shown in FIG. 4, the height adjusting bolt (3) is not provided with the expanding portion. You may employ | adopt the structure which the adhesive agent accumulation part (10) was formed in the space on the upper surface side. Of course, also in this case, it is necessary to provide the adhesive injection hole (11) in the peripheral wall of the female screw member (4) at a position communicating with the adhesive reservoir (10) (see FIG. 4).

In the case where the expanding portion (4b) is provided, the outer surface of the expanding portion (4b) may project outward from the outer surface of the female screw portion (4a) as shown in FIG. Further, as shown in FIG. 3, it may be formed flush with the outer surface of the female screw portion (4a), or the female screw portion (4a).
The outer surface of may be configured to project more outward than the outer surface of the expansion portion (4b).

(3a) is screwed. In this female screw member (4), the inner diameter is the same from the upper end to the lower end, and the outer diameter is also the same from the upper end to the lower end.

As shown in FIG. 5, an adhesive agent guiding groove (12) continuous in the axial direction of the female screw member is formed on the inner surface of the female screw member (4a), and an adhesive agent is further formed on the peripheral wall of the female screw member (4). An injection hole (11) is formed so that the adhesive injection hole (11) communicates with the upper end of the adhesive guide groove (12).

Further, the lower end position (Q) of the adhesive guiding groove (12) provided on the inner surface of the female screw part (4a) is located above the lower end position (R) of the female screw part (4a). The adhesive that has been arranged and has descended through the adhesive guide groove (12) is blocked by the lower end of the female screw portion (4a) and moves below the lower end position (Q) of the guide groove (12). Therefore, it is prevented from flowing out of the screwing space.

The floorboard laying operation using the floorboard supporting device shown in FIG. 5 is performed in the same manner as in the case of the first aspect of the present invention (the explanation is omitted because it is similar to the above). Even if there is a case where the floor board supporting device (1) in which the adhesive is not unintentionally injected and the screwing portion is not adhered and fixed exists, in the present invention, the peripheral wall of the female screw member (4) is prevented. An adhesive injection hole (11) is provided, and the adhesive injection hole (1
Since 1) is made to communicate with the adhesive guide groove (12) (see FIG. 5), it is possible to perform the subsequent adhesive fixing work of the screwed portion very easily and in a short time. Is.

That is, when it is necessary to repair after the laying work is completed due to forgetting to inject the adhesive, the laying condition of the floor plate is left as it is, and the worker enters the underfloor space and first raises the height of the floor plate supporting device. It is only necessary to adjust the depth, and then inject the adhesive (20) through the adhesive injection hole (11) provided in the female screw member (4). This adhesive injection hole (1
The adhesive (20) injected from 1) enters the screwing space mainly through the adhesive guiding groove (12) due to its own weight, and thereby the screwing portion, that is, the bolt (3) and the female screw member. (4) and can be fixed by adhesion. Thus, the worker enters the underfloor space and enters the adhesive (2) through the adhesive injection hole (11).
By simply injecting 0), the subsequent adhesive fixing of the screwed portion can be completed.

Also in the floor board supporting device (1) of the second invention, the number of the adhesive injection holes (11) provided in the peripheral wall of the female screw member (4) is not particularly limited, and as shown in the configuration of FIG. The number may be one or two or more.

Also in the second aspect of the invention, since the adhesive guide groove (12) is continuously extended in the vertical direction, the adhesive can be supplied to the screwing space more efficiently. It is preferable in that respect. In addition, in the "vertical direction" here,
It goes without saying that the axial direction of the female screw member (4) is included in the same manner as described above, but other vertical directions slightly inclined with respect to the axial direction and spiral vertical directions with a large inclination are also included.

In the embodiment shown in FIG. 5, no adhesive guide groove is formed in the upper part of the adhesive injection hole (11), but the adhesive injection hole (11) on the inner surface of the female screw member (4) is formed. It is also possible to adopt a structure in which an adhesive guide groove is formed in a position communicating with the injection hole (11) also at the upper position of (4), and the adhesive guide groove extends to the upper end of the female screw member (4). It may be formed.

[0054]

According to the floor board supporting apparatus of the first aspect of the present invention, since the adhesive injection hole is provided in the peripheral wall of the female screw member, and the adhesive injection hole communicates with the adhesive reservoir. The adhesive injected from the adhesive injection hole is retained in the adhesive reservoir, and then enters the gap (screw space) between the male screw portion and the female screw portion by its own weight so that the screw portion can be adhesively fixed. Therefore, even if unintentionally forgetting to inject the adhesive and the screwing part was not fixed by adhesion, the operator simply enters the underfloor space and injects the adhesive from the adhesive injection hole to perform the subsequent screwing. Adhesive fixing of parts can be completed. In this way, the subsequent adhesive fixing work can be facilitated, and the working time can be extremely shortened to reduce the cost. Further, the adhesive is not supplied to the screwing space by transfer, but the adhesive is supplied to the screwing space by its own weight drop of the adhesive staying in the adhesive reservoir, so that the adhesive is adhered to the screwing space. The agent is sufficiently supplied, and excellent adhesive fixing strength can be obtained in the screwed portion, whereby the floor plate can be secured without feeling of floating or sinking and floor squeaking.

An expanding portion is provided on the upper part of the female screw member,
When the adhesive reservoir is formed between the expanding portion and the height adjusting bolt, the adhesive is reliably supplied to the screwing space, further improving the adhesive fixing strength. it can.

At least one of the outer surface of the male screw portion of the height adjusting bolt and the inner surface of the female screw portion of the female screw member is formed with an adhesive guide groove which is continuous in the vertical direction and whose upper end communicates with the adhesive reservoir. In this case, the screwing space is filled with the adhesive more sufficiently, so that the adhesive fixing strength can be further improved.

When the lower end of the adhesive guiding groove is arranged above the lower end position of the threaded portion in which the adhesive guiding groove is provided, the adhesive can effectively flow out of the screwing space. Can be prevented.

According to the floor board supporting apparatus of the second invention,
An adhesive injection hole is provided in the peripheral wall of the female screw member, and this adhesive injection hole communicates with the adhesive guide groove. The threaded portion can be adhesively fixed by entering the gap (threading space) between the male screw portion and the female screw portion through the groove. Therefore, even if unintentionally forgetting to inject the adhesive and the screwing part was not fixed by adhesion, the operator simply enters the underfloor space and injects the adhesive from the adhesive injection hole to perform the subsequent screwing. Adhesive fixing of parts can be completed. In this way, the subsequent adhesive fixing work can be facilitated, and the working time can be extremely shortened to reduce the cost. Further, the adhesive is not supplied to the screwing space by transfer, but the adhesive is supplied to the screwing space by its own weight drop of the adhesive staying in the adhesive reservoir, so that the adhesive is adhered to the screwing space. The agent is sufficiently supplied, and excellent adhesive fixing strength can be obtained in the screwed portion, whereby the floor plate can be secured without feeling of floating or sinking and floor squeaking.

In the second aspect of the invention, when the lower end of the adhesive guiding groove is arranged above the lower end position of the female screw portion, the adhesive can be effectively prevented from flowing out of the screwing space. Becomes
