[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating panel used when constructing a heat insulating double floor by forming a space between an existing foundation floor surface in various buildings such as a detached house and an apartment house, and a heat insulating double floor using the same. It relates to the construction method.
[0002]
[Prior art]
The double floor is constructed such that a plurality of floor panels (floor board materials) are supported at a certain height by a plurality of support legs arranged on the foundation floor. For example, Japanese Patent Laid-Open No. 3-17348 and In Kaihei 4-116537, a unit supporting leg group comprising a bar-shaped leg and a receiving plate mounted on the upper end of the bar-shaped leg so as to be vertically adjustable, and a rectangular and / or square floor panel group A construction method of a dry double floor using a combination of the two is disclosed.
An example of a conventionally known unit support leg is as shown in FIG. 7, and a floor contact base 11 made of a relatively hard elastic material such as rubber or synthetic resin, and is erected on the base 11 so as to be rotatable. Level adjustment nut 17 having a rod-like leg portion comprising support bolts 13 formed on the outer periphery, an annular support portion 18 projecting laterally at the substantially central portion of the outer periphery, and an upper portion of the level adjustment nut 17 at the central portion. Is formed of a square or rectangular support plate 19 having an insertion hole 20 into which is inserted.
[0003]
The support bolt 13 is integrally provided with an annular flange portion 14 projecting sideways on the outer peripheral surface at a position spaced apart from the lower end by a predetermined distance, and a screw portion is formed above the flange portion 14. A groove portion 16 is formed on the top end face of 13 for fitting the tip of the rotary tool. Then, by inserting the base end round bar portion 15 of the support bolt 13 into the center hole 12 of the floor contact base 11, the support bolt 13 can freely turn to the floor contact base 11 with the flange portion 14 as a support portion. It will be in the state erected in. On the other hand, the level adjusting nut 17 is fitted into the insertion hole 20 of the support plate 19 and is firmly attached to the support plate 19 by expanding the upper portion thereof. At the same time, an adhesive reservoir 22 is formed above the level adjusting nut 17. By screwing the upper end portion of the screw portion of the support bolt 13 into the level adjusting nut 17 fitted in the insertion hole 20 of the support plate 19 in this way, the unit support leg 10 is assembled as shown in FIG.
In the unit support leg 10 having such a structure, the level adjusting nut 17 moves up and down by inserting the tip of a rotating tool such as a screwdriver into the groove 16 on the top end surface of the support bolt 13 and rotating the support bolt 13. The floor level of the floor panel supported by the support plate 19 can be adjusted.
[0004]
An example of construction in the case of constructing a double floor using the unit support legs 10 assembled as described above is as follows. First, along the predetermined height of the room wall or the partition 31, as shown in FIG. A joist (or joist unit) 32 is provided, and one side of the floor panel 33 is supported thereon. The other edge of the floor panel 33 that does not contact the joist is mounted and attached to the unit support leg 10 placed on the foundation floor (concrete slab) 30 at a predetermined pitch in a cantilevered state. The unit support leg 10 and the floor panel 33 are attached via a double-sided adhesive sheet 21 attached to the upper surface of the support plate 19 of the unit support leg 10 and the floor panel 33 is pressure-bonded to the double-sided adhesive sheet 21 when the floor panel is laid. And temporarily fix. The insertion hole 20 of the support plate 19 of the unit support leg 10 is exposed from the edge of the floor panel 33, and the support bolt 13 is turned by a screwdriver or the like through the insertion hole 20, so that the level (or support plate 19) of the floor panel 33 is reached. Adjust the top surface position of.
[0005]
Similarly, adjacent floor panels are mounted on the unit support legs 10 that have already been installed with a predetermined gap that allows the level adjustment of the floor panel 33, and the other unit support legs 10 are similarly placed and attached. Such work is repeated for each floor panel, the floor panel is constructed in a predetermined area, the floor level is adjusted as necessary, and then the floor panel 33 is nailed to the support plate 19 of the unit support leg 10 to The panel 33 is fixed to the unit support leg 10, and an adhesive is injected from the adhesive reservoir 22 above the support bolt 13 to bond and fix between the level adjusting nut 17 and the support bolt 13. Thereafter, if necessary, a plywood 34 is laid on the floor panel 33 or a relatively rigid adhesive tape is applied so as to cover a gap between adjacent floor panels, and then a CF sheet, a carpet. Floor finishing materials (not shown) such as tatami mats, wooden floor materials, and tile carpets are laid and the work is completed.
[0006]
[Problems to be solved by the invention]
By constructing as described above, a double floor is constructed. However, in recent years, there has been a demand for improvement of indoor heat insulation and sound insulation, and in order to add heat insulation and sound insulation to the floor as well, It has been proposed to provide heat and sound insulation materials such as glass wool, extruded polystyrene foam, beaded polystyrene foam, and urethane foam in the structure. For example, the present applicant has already proposed a construction example in which a joist and a heat insulating material are arranged on a support plate of a unit support leg and a floor panel is placed thereon (Japanese Patent Laid-Open No. 7-305442). However, in this method, for example, a joist material that is narrower than the support plate is placed on the unit support leg, and a heat insulating material is placed between the joists, and then a floor panel is laid. A heavy joist is required for the construction of the heavy floor, which is difficult in terms of workability and construction cost.
[0007]
On the other hand, as a panel material integrated with a heat insulating material, Japanese Utility Model Laid-Open No. 3-25707 proposes a load-bearing panel structure in which a structural laminate is bonded to at least one side surface of a core material made of a heat insulating material. This load-bearing panel structure is primarily intended for use on house wall boards, but is taught to be applicable to floor boards.
However, when using joists, it is considered that such a large problem does not occur, but such a panel material using a heat insulating material such as urethane foam as a core material is supported by the unit support legs as described above. When used as a double-floor floor panel, for example, in a structure where structural laminates are laminated on one side of the core material by receiving a load for many years by repeated walking or placing objects, the unit support legs The shrinkage of the foamed urethane at the supported portion is large, and even in the structure in which the structural laminate is laminated on both side surfaces of the core material, the foamed urethane shrinks as a whole, and the shrinkage rate varies depending on the floor area. Therefore, there is a problem that a step is generated between adjacent floor panels, the floor surface is partially sunk, and a uniform floor surface level cannot be maintained for many years.
In addition, the heat insulating property is exhibited by providing a heat insulating material under the entire floor, and there is a gap between adjacent floor panels like a double floor having a structure in which the edge of the floor panel is supported by the unit support legs as described above. If so, the effect is reduced.
[0008]
Accordingly, an object of the present invention is to provide a heat insulating panel excellent in workability and capable of laying a heat insulating layer very easily by the unit support legs as described above, and a heat insulating double floor using the same. It is to provide a construction method.
Furthermore, the object of the present invention is that there is no problem such as generation of a step between adjacent floor panels or subsidence of a floor surface even when a load is applied for many years due to repeated walking or placement of objects, and a uniform floor surface level. It is an object to provide a heat insulating panel that can easily and stably construct a heat insulating double floor capable of maintaining the heat resistance for many years, and a method for constructing a heat insulating double floor using the heat insulating panel.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, according to one aspect of the present invention, a thermal insulation panel is provided. The basic aspect is a thermal insulation panel used to construct a thermal insulation double floor supported by a unit support leg having a support plate mounted on the upper end of a leg member so as to be adjustable in height. A notch portion having a shape corresponding to a part of the shape of the support plate is formed at a predetermined portion, and a protruding portion is formed so as to extend from the edge portion to the upper portion of the notch portion. It is a feature.
In a preferred aspect, the protrusion is formed at least on a protrusion extending along a pair of opposing panel side edges, and in a more preferable aspect, the protrusion connects each heat insulating panel. In this case, the opposing panel side edges are formed rotationally symmetrically so as to be substantially continuous.
[0010]
According to the other aspect of this invention, the construction method of the heat insulation double floor | bed using the above heat insulation panels is also provided. A basic aspect of this construction method is that a plurality of unit support legs are arranged at a predetermined pitch corresponding to the shape of the floor panel on the floor surface of the foundation floor, and the edge of the floor panel is the unit support leg. When constructing a double-floor floor foundation that is laid to be supported by a support plate and laid at a predetermined height level, a part of the shape of the support plate at a predetermined position on the edge before laying the floor panel A notched portion having a shape corresponding to the shape of the heat insulating panel and a protruding portion formed so as to extend from the edge portion to the upper portion of the notched portion. A heat insulating layer is laid over the projecting portion so as to be placed on the support plate while being fitted to the support plate of the support leg. A construction method according to a preferred embodiment uses a heat insulating panel formed on a ridge extending along at least a pair of opposing panel side edges, and a floor panel is laid against the ridge. It is characterized by doing.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The construction of the insulated double floor according to the present invention basically uses a plurality of unit support leg groups and floor panel groups as described above, and opposing unit support legs arranged on the basic floor surface at a predetermined pitch. A floor panel is laid between the support plates (between the support plate of the unit support leg and the joist or the joist member of the joist unit in the case of a wall or partition) and laid at a predetermined height level. When laying the floor base, before laying the floor panel, a notch having a shape corresponding to a part of the shape of the support plate is formed at a predetermined position of the edge, and the notch is formed from the edge. It is characterized by laying a heat insulation layer using the heat insulation panel in which the protrusion part was formed so that it might extend to the upper part.
[0012]
And in construction of such a heat insulation panel, it lays over so that the above-mentioned projection part may be laid on a support board, fitting the above-mentioned notch part with the support board of a unit support leg. Therefore, the heat insulating layer can be constructed very easily and with good workability.
The heat insulation double floor constructed in this way is excellent in heat insulation due to the presence of the heat insulation layer, and the floor panel is supported in a state where the edge of the floor panel is directly placed on the support plate of the unit support leg. Therefore, even if it receives a load for many years due to repeated walking, placing objects, etc., there are no problems such as steps between adjacent floor panels and sinking of the floor surface, and a uniform floor surface level for many years Can be maintained.
[0013]
Moreover, in the case of the heat insulation panel formed in the protrusion part extended along a pair of panel side edge part at which the said protrusion part opposes at least, this protrusion part is utilized as a positioning part, and it is a floor panel, abutting against this Therefore, the floor panel can be laid very easily.
Further, when the protrusions are formed rotationally symmetrically on the opposing panel side edges so as to be substantially continuous when the respective heat insulation panels are connected, the heat insulation is provided in the gaps between the adjacent floor panels. Since the protruding portion of the panel exists and functions as a heat insulating joint material, the heat insulating property is further improved.
[0014]
As the thermal insulation panel, any semi-rigid or rigid plastic foam that exhibits sufficient durability and thermal insulation can be used, preferably closed-celled or semi-closed-cell foamed urethane, beaded polystyrene foam Extruded polystyrene foam can be suitably used. In particular, a beaded polystyrene foam is preferable from the viewpoints of high strength, good moldability (molding is possible), and low water absorption. Such a plastic foam has a considerably strong compressive strength, is excellent in heat insulating properties and the like, has no hygroscopic property, and their properties hardly change over a long period of time. Moreover, since it is lightweight and easy to process such as cutting and drilling, it is advantageous from the viewpoint of handleability.
By laying such a heat insulating panel under the floor panel, a heat insulating double floor having excellent heat insulating properties is obtained.

Since it adheres, the heat insulation panel 1 can be laid easily and stably. At this time, the notch 2 of the heat insulating panel 1 serves as a positioning guide for the support plate 19, so that the pitch of the installation positions of the unit support legs 10 does not shift. The installation of the floor panel after the installation of the heat insulation panel, the adjustment of the floor surface level, and the like are the same as in the conventional method described above, but the protrusion 3 of the heat insulation panel 1 previously installed is used as a positioning part. Since the floor panel 33 can be laid while butting, the floor panel can be laid very easily.
[0018]
In addition, the formation location and the number of the notch portions 2 of the heat insulating panel 1 are appropriately set depending on the size of the floor panel 33 to be used and the number of unit support legs 10 installed per unit area corresponding to the size. Further, the number of the protrusions 3 can be set as appropriate, and may be formed so as to extend to the upper part of all the notch parts 2 based on a geometric aspect considering the connection state of the heat insulating panels arranged adjacent to each other. Good. Further, as the unit support legs 10, all conventionally known unit support legs can be used as long as they have a structure having a support plate.

When a heat insulating layer is formed using such a heat insulating panel 1b, the protrusions 3b of the heat insulating panel 1b exist in all the gaps between the adjacent floor panels 33 and function as a heat insulating joint material. The property is even better.
[0021]
When the heat insulation layer is formed using the heat insulation panel as described above, the insertion hole 20 of the unit support leg 10 remains exposed, and the floor panel 33 to be laid thereafter has a gap between the adjacent floor panels. Since it arrange | positions so that it may arise, in the notch part 2, it will be in the state opened to the up-down direction. Therefore, the tip of a rotating tool such as a screwdriver is inserted through the opening formed in the notch 2, and the support bolt 13 of the unit support leg 10 installed below is turned to adjust the floor level. Can do.
[0022]
Although the preferred embodiments of the present invention have been described above, the present invention can be used to simplify a heat insulating double floor using a heat insulating panel provided with a protrusion (projection) for hooking on a support plate of a unit support leg.

For example, what fixed the heat insulation panel of the shape mentioned above to the back surface of a floor panel by arbitrary means, such as adhesion | attachment and a nail | claw stop, can also be used. In addition, various conventionally known materials can be used as the unit support legs and the heat insulation panel material, and the shape of the notch of the heat insulation panel can be arbitrarily changed according to the shape of the support plate of the unit support leg to be used. Can do.
[0023]
Further, the support bolt 13 of the unit support leg 10 may be either a solid support bolt or a hollow support bolt made from a hollow pipe. However, in the case of a hollow support bolt, for level adjustment, an upper and lower through hole is provided in the center of the floor contact base 11, or a groove extending radially (for example, cross-shaped) from the through hole is formed on the lower surface thereof. When the adhesive is injected into the adhesive reservoir 22 above the nut 17, the adhesive flows down through the support bolts and further penetrates into the groove portion, so that the floor contact base 11 can be bonded to the foundation floor 30. . Therefore, it is advantageous that the fixing of the support bolt and the level adjusting nut and the fixing of the floor contact base and the foundation floor can be performed simultaneously by a single adhesive injection operation.
[0024]
【The invention's effect】
