As described above, in the construction of a double floor using the conventional unit support leg 101, as shown in FIG. The unit support legs support several places, and in general, each unit support leg 101 is about 88 × 88.
It has a support plate with a size of mm and a pitch P of about 450 mm.
Placed in 2 . Therefore, the adjacent unit support legs 10
Since the space between the first support plates is wide, when a load is applied to a portion of the floor panel 114 where the unit support legs 101 are not arranged, a bending occurs. Generally, when walking, one of the floor panels receives weight, so the floor panel under load bends, but the adjacent floor panels do not bend, and there is no step between the floor panels. Occurs. Therefore, if a flexible floor finishing material such as a cushion floor is directly applied on the laid floor panel 114 without laying the plywood 115, the flexure of the floor panel due to the load is transmitted to the cushion floor, Partial tensile stress may be generated, and blistering or peeling may occur in that part. In addition, there is a problem in that the user feels a sense of discomfort by feeling the step between the adjacent floor panels caused by the load application on the sole of the foot.

In order to solve such a problem, it is conceivable that the unit support legs are arranged with a narrow pitch P 2. However, in this case, the cost is significantly increased and the unit support legs are arranged and arranged. There are problems that the number of level adjustment work increases, workability and workability are significantly reduced, and the final floor level adjustment work becomes complicated. Therefore, conventionally, after laying a floor panel, plywood having a thickness of 4 to 6 mm is generally discarded on the entire upper surface thereof. Therefore, it is inevitable that the material cost of the waste plywood will increase, the labor cost of the waste plywood will increase, and the construction period will be prolonged. However, there is a need for a low-cost double-floor construction method that takes as little effort as possible, reflecting the current labor shortage and rising prices.

In order to eliminate the need for laying the waste plywood, it is conceivable that the floor panels will be connected and integrated by actual stripping or the like. However, since particleboards used for floor panels generally have large expansion due to moisture absorption, floor panels press against each other and a rush phenomenon occurs, so
This method cannot be adopted. In addition, a strip plate is attached in advance so as to be bridged over the arranged unit support legs, and on this,
So that the edge of the floor panel is placed and supported, that is,
There is also a method of constructing so that the gap between adjacent floor panels is on the strip. However, although this method is satisfactory in performance, it is not widely used because the work is complicated, the construction efficiency is poor, and the cost is increased.

Further, as described above, in the conventional double floor construction using the unit support legs, the floor panel 114 is attached to the support plate 108 of the unit support legs 101 when the floor panel is laid.
Press the adhesive sheet 110 on the upper surface to temporarily fix it.
After constructing the floor panel 114 in a predetermined area, the floor panel 114
The floor panel 114 is fixed to the unit support leg 101 by nailing the support plate 108 from the bottom. That is, since the pressure-sensitive adhesive sheet has no durability, it is used only for temporary fixing, and the floor panel and the unit supporting legs are finally fixed by nailing. However, even if nailing is used, walking vibrations are repeatedly applied after a long period of use, so that the fixing due to nailing may be loosened, resulting in floor ringing. When fixing the floor panel and the unit support legs, it is possible to use adhesive instead of nailing, but applying adhesive one by one on the upper surface of the support plate of the unit support leg only increases the work process. Not
There is a problem that the adhesive adheres to the hands, clothes, and surroundings of the worker and stains them, and the treatment and cleaning are required thereafter, resulting in a significant decrease in workability, which is not practical.

If the support bolts of the unit support legs and the level adjusting nuts are not securely fixed after the floor is constructed, the level adjustment error or the screwing of the screwing portion due to the rotation of the support bolts due to repeated walking on the floor surface or the like. There are problems such as backlash, falling floor, squeaking of floor, and step difference between floor panels. Therefore, it is necessary to fix the support bolt of the unit support leg and the level adjusting nut with an adhesive or the like. The fixing of the support bolt and the level adjusting nut is performed after the floor level is adjusted. Therefore, if the fixing between the floor panel and the support plate of the unit supporting leg is performed when the floor panel is laid by using the adhesive as described above, the work of applying the adhesive is troublesome and the workability and the workability are low. Is significantly reduced.

In the construction method, such unit support legs are arranged on the floor surface of the foundation floor at a predetermined pitch corresponding to the shape of the floor panel, and a plurality of floor panels have the edge portions of the support plate of the unit support leg long. Since the unit supporting legs are arranged along a side with a predetermined gap so as to be supported by the unit supporting legs, even if the unit supporting legs are arranged on the foundation floor at the same pitch as the conventional method,
The space between the support plates of adjacent unit support legs becomes narrower,
Even if a load is applied to a portion of the floor panel where the unit support legs are not arranged, the floor panel is not easily bent, and there is almost no step between adjacent floor panels. Therefore, even if a flexible floor finishing material such as a cushion floor is directly applied without laying a waste plywood on the laid floor panel, swelling or peeling of the cushion floor due to bending as in the past, There is no problem such as a feeling of strangeness when stepping on the step between the adjacent floor panels with the sole of the foot. In particular, by covering the gap between adjacent floor panels with a thin sheet having rigidity, such a problem can be almost completely eliminated. As a result, it is possible to construct CF sheets, carpets, etc. without the need to put up a waste plywood as in the past, and the waste plywood becomes unnecessary, and the material cost of the waste plywood and the labor to put the waste plywood can be saved. Material cost, labor cost can be saved, construction period can be shortened, and floor construction can be performed at lower cost.

In another aspect of the present invention, the support plate of the unit support leg is a rectangle whose long side is twice or more the length of the short side, and has an adhesive flowing portion on its upper surface. Therefore, a plurality of floor panels are laid on the unit support legs arranged on the floor surface of the foundation floor with a predetermined gap so that the edge portions thereof are supported in the above arrangement mode, and the adjacent floors are adjacent to each other. When the adhesive is injected from the above-mentioned gap between the panels, the injected adhesive flows in the adhesive flow part formed on the support plate of the unit support leg and then solidifies, so that the adhesive between the support plate and the floor panel is solidified. The adhesion area increases, and you can surely adhere. for that reason,
Even if walking vibration is repeatedly applied to the floor panel, there is no fear of loosening as in the case of fixing with only nails, and floor squeaking can be almost permanently prevented. Also, instead of applying the adhesive to the upper surface of the support plate of the unit support legs one by one, after laying the floor panels, the adhesive may be injected from the gap of the unit support leg arrangement portion between the adjacent floor panels. Since it is good, the workability is extremely good, and the problem that the adhesive adheres to the operator's hand, clothes, or the surroundings and stains is greatly alleviated as compared with the coating work.

In a preferred mode of the unit support leg of the present invention, an expanding portion is formed on the upper portion of the level adjusting nut to provide an adhesive reservoir, and preferably the adhesive reservoir is used to support the supporting member. It is configured to communicate with the adhesive flow part on the upper surface of the plate. With such a configuration, the adhesive is supplied between the floor panel and the support plate through the adhesive flow section and the support bolt and the level through the adhesive reservoir by one injection operation of the adhesive. Since it is also supplied to the threaded portion with the adjustment nut, the fixing between the floor panel and the support plate of the unit support leg and the locking of the support bolt (fixation of the support bolt and the level adjustment nut) are done at the same time. It can be carried out.

(2) A height difference is formed on the upper surface of the support plate to form a recess, and when a floor panel is laid, a gap is formed between the support plate and the floor panel, and the adhesive is flowed into this gap. As a preferable mode of forming such a recess, the following modes can be mentioned. (A) A partially thin sheet material such as a double-sided pressure-sensitive adhesive sheet (hereinafter, simply referred to as a pressure-sensitive adhesive sheet), a single plate, or resin-impregnated paper is attached to the upper surface of the support plate. Preferably, at least two thin sheet-like materials are attached to the periphery of the upper surface of the support plate so that recesses are formed between these sheet-like materials. (B) The upper surface of the support plate is partially ground to form a recess. In the present invention, the above-described mode of forming the adhesive flow part may be adopted alone, or these may be combined arbitrarily. In particular, when the concave portion is formed by using the adhesive sheet, or when the adhesive sheet is used in combination, the floor panel can be temporarily fixed by using the adhesive sheet, which is good in workability and is a preferable mode. In addition, when laying the floor panel, it is possible to prevent the position of the unit support legs from slipping or falling during construction by crimping the floor panel to the adhesive sheet attached to the support plate and temporarily fixing it. can get.

In order to smoothly supply the adhesive to the threaded portion of the support bolt 4 and the level adjusting nut 7, one or a plurality of pieces are provided in the axial direction on the inner peripheral thread portion of the level adjusting nut 7. It is desirable to form grooves, and it is preferable that each groove be stopped up to the vicinity of the lower end of the level adjusting nut 7 to form a non-penetrating groove to prevent the adhesive from dripping. Alternatively, it is possible to form a groove in the axial direction at the upper end of the threaded portion of the support bolt 4. When it is not necessary to temporarily fix the floor panel with the double-sided pressure-sensitive adhesive sheet, a thin sheet material such as a single plate or resin-impregnated paper may be attached instead of the pressure-sensitive adhesive sheet. It is also possible to adhere sheet-like materials to the four sides of the upper surface of the support plate 9 to completely prevent the adhesive from sagging. After laying the floor panels, the gap B between the adjacent floor panels is covered with a thin sheet having rigidity as shown in FIG. There is no problem such as a stepped portion, and by using a double-sided adhesive tape, it can be used for fixing a floor finishing material.

The size of the support plate may be determined from the size of the floor panel and appropriately designed so that the distance between the end edges of the support plates of the adjacent unit support legs becomes small. However, since this floor panel usually has a large bending strength due to its application, it is not necessary to set the spacing to 0, and the floor panel material to be used can be set between 50 and 200 mm. It may be determined experimentally accordingly. Next, when a concrete construction example is shown, length 220 ×
A unit support leg with a plywood support plate having a width of 88 x a thickness of 21 mm, and a length of 1820 x a width of 600 x a thickness of 20 mm
Using the floor panel (particle board) of No. 2, a double floor was constructed in the arrangement shown in FIG. 3 under the condition that the distance between the support plates was 191 mm and the distance between the floor panels was 5 mm. The adhesive for fixing the floor panel was injected from the gap B between the floor panels and left for 7 days. After that, an adhesive tape with a width of 20 mm was attached and closed in the gap of the floor panel, and a cushion floor (thickness 1.8 mm) was attached to the entire floor surface using a special adhesive. Stable double floors could be constructed with good workability without any swelling or peeling and no step in the gap between floor panels.

As the adhesive used for fixing the floor panel, epoxy type, urethane type, vinyl acetate type, etc. can be used, but when fixing the support bolt 4 and the level adjusting nut 7 at the same time, epoxy is used. Adhesives based on urethane and urethane are suitable. In order to make the adhesive flow sufficiently into the adhesive flow part, a low viscosity is preferable, but if the viscosity is too low, it is easily absorbed by the material, while if the viscosity is too high, the flowability is poor and in either case However, it is not preferable because it is difficult for the adhesive to reach the peripheral portion of the support plate. The viscosity of the adhesive is selected in consideration of the shape, area, material, etc. of the adhesive flow part.
The adhesive is put in a container such as a tube or a pump, pressed by a nozzle having a narrow tip, pushed out, and injected into an adhesive reservoir or an adhesive flowing part.

FIGS. 6 and 7 show a modification of the above-described embodiment, in which the adhesive sheets 12 are attached to opposite ends of the upper surface of the support plate 9a of the unit support leg 1a, and the periphery of the insertion hole of the support plate 9a. Also, the adhesive sheet 12a is attached, and further, on the upper surface of the support plate between the adhesive sheets 12 and 12a, part of the groove is exposed in the gap B between the adjacent floor panels 20 when the floor panel is laid. The embodiment is different from the above embodiment in that a plurality of striped grooves 15 are formed in a direction orthogonal to the longitudinal direction. Furthermore, an adhesive reservoir 13a is formed by expanding the upper portion of the level adjusting nut 7a itself. Therefore, in the case of this embodiment, when the floor panel 20 is laid and then the adhesive is injected into the groove forming portions of the adhesive reservoir 13a and the support plate 9a, the adhesive is applied to the support bolt 4 and the level adjusting nut 7a.
Of the support plate 9a through the groove 15 and between the floor panel 20 and the support plate 9a.

As described above, according to the unit support leg of the present invention and the double floor construction method using the same, the following effects and advantages are obtained. (A) A unit support leg equipped with a rectangular support plate whose long side is at least twice as long as the short side is used, and a plurality of floor panels are provided with their edges along the long side of the support plate of the unit support leg. Therefore, even if the unit support legs are arranged on the foundation floor at the same pitch as the conventional method, the adjacent unit support legs are The spacing between the support plates is narrowed, and the reinforcement effect that is substantially the same as when a strip plate is interposed is obtained, and bending does not easily occur even if a load is applied to the part of the floor panel where the unit support legs are not arranged. , There is almost no step between adjacent floor panels. In particular, by attaching a wide adhesive tape so as to cover the gap between the floor panels, it is possible to significantly reduce the occurrence of steps. Therefore, even if a flexible floor finishing material such as a cushion floor is directly applied without laying a waste plywood on the laid floor panel, swelling or peeling of the cushion floor due to bending as in the past, There is no problem such as a feeling of strangeness when stepping on the step between the adjacent floor panels with the sole of the foot. Moreover, since the shape of the support plate of the unit support leg is rectangular and the length of the long side is twice or more the length of the short side, the peripheral portion of the floor panel to be supported can be effectively reinforced with a small amount of material. . Moreover, since the unit support legs can be installed at appropriate intervals, less material is required compared to the case where the strips are preliminarily laid between the unit support legs, and no extra labor is required in the construction. It does not take. (B) As a result, CF sheets, carpets, etc. can be constructed without the use of conventional plywood, and the plywood is no longer needed. The material cost of the plywood and the plywood are stretched. It saves labor, saves material cost, labor cost, and shortens construction period, and floor construction can be performed at lower cost.

(C) By providing an adhesive flow part such as a groove or a recess on the upper surface of the support plate used for supporting the floor panel,
The support plate and the floor panel can be reliably bonded together, and even if repeated vibrations are applied to the floor panel, there is no risk of loosening as when fixing with only nails, and floor squeaking can be prevented almost permanently. . Also, instead of applying the adhesive to the upper surface of the support plate of the unit support legs one by one, after laying the floor panels, the adhesive may be injected from the gap of the unit support leg arrangement portion between the adjacent floor panels. Since it is good, the workability is extremely good, and the problem that the adhesive adheres to the operator's hand, clothes, or the surroundings and stains is greatly alleviated as compared with the coating work. (D) Adhesion is achieved by forming an expanded portion at the upper part of the level adjusting nut to provide an adhesive reservoir and preferably by providing an adhesive flowing portion on the upper surface of the support plate so as to communicate with the adhesive reservoir. By a single injection operation of the agent, the fixing between the floor panel and the supporting plate of the unit supporting leg and the fixing of the supporting bolt and the level adjusting nut can be performed at the same time. Therefore, workability and workability are improved, and the floor surface level adjustment accuracy is also increased. Further, there is no problem such as a level adjustment error caused by loosening of the support bolts due to repeated walking on the floor surface, a floor drop due to looseness of the screwed portion, a floor squeal, and a step between floor panels. (E) In addition, by sticking the adhesive sheet together with the adhesive flow section to the support plate of the unit support leg, the floor panel can be pressure-bonded to the adhesive sheet and temporarily fixed when the floor panel is laid. The position of the unit support leg can be prevented from shifting or falling down, and the workability of double floor construction can be improved.
