Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention includes a protrusion for height adjustment on the lower surface and a recess for fitting the entire protrusion on the lower surface or the upper surface. Accordingly, the present invention relates to a floor heat insulating plate having a height adjusting function that can reduce the bulkiness when a plurality of sheets are stacked and can protect the protrusion.

(Background of the Invention and Prior Art) A heat insulating floor is constructed by fitting a heat insulating plate between adjacent joists and by sticking the floor plate so that the upper surface thereof is in close contact with the lower surface of the floor plate. ing.

In actual practice of such floor insulation work, the joists are warped or there is an error in the manufacturing dimensions with the joists, so the top surface of the joists fixed on the Daihiki is finished to a uniform height. It is usually not. Therefore, when the heat insulating plate is fitted between the joists, it often happens that the upper surface of the heat insulating plate partially projects from the upper surface of the joist and vice versa.

If it is assumed that the floorboard is nailed to the joist without correcting the unevenness of the height of the upper surface of the main body, as shown by exaggerating the floorboard a in FIG. Is generated, and the nails rub against the nailed portion d to cause floor squeal, and the unevenness of the height of the upper surface of the heat insulating plate e causes a gap between the heat insulating plate e and the floor plate a. There is also a problem that a poor adhesion portion f is generated on the sheet and the heat insulating effect of the heat insulating plate e is impaired.

Therefore, in order to solve such a problem, the applicant of the present application discloses in Japanese Patent Application No. 1-26483 that a protrusion i for height adjustment which can abut the upper surface h of the large pull g is provided as shown in FIG. An integrally formed heat insulating board for floor j made of foamed synthetic resin and arranged on the lower surface was proposed. When performing heat insulation construction on the floor using the floor heat insulating plate j, the upper surface of the floor heat insulating plate partially projects from the joist upper surface due to uneven thickness of the joist as shown in FIG. Even if it is in the state, the entire upper surface of the floor insulating plate is the surface of the joist upper surface as shown in FIG. 4 due to the appropriate compression deformation (see FIGS. 4 and 6) accompanying the pressing of the insulating plate on the protruding portion. The height can be easily adjusted so as to be in the one state, and therefore the unique effect that the upper surface of the floor heat insulating plate can be surely brought into close contact with the lower surface of the floor plate is exhibited.

(Problems to be Solved by the Invention) However, the floor heat insulating plate having the above-mentioned configuration has the following problems in the transportation stage, and there is room for improvement.

That is, when transporting factory-produced floor insulation plates with protrusions, the required number of floor insulation plates were stacked in sequence with the protrusions facing downward, and then packed. When shipping as a product, firstly, the protrusion length of the protrusion is multiplied by the number of stacked sheets,
There is a problem in that it is bulky as compared with a case where flat heat insulating plates without protrusions are stacked in close contact with each other, which causes an increase in transportation cost.

Secondly, when the heat insulating plates for floors with protrusions are stacked and packed in multiple stages, the protrusions 10 with low strength may be crushed, and the protrusions 10 have the purpose in the stage of use at the construction site. In some cases, the height adjustment function was not effective.

An object of the present invention is to provide a floor heat insulating plate having a height adjusting function capable of solving the above problems.

(Means for Solving the Problem) A floor heat insulating plate (hereinafter, referred to as a floor heat insulating plate) 1 having a height adjusting function according to the present invention is made of a synthetic resin which is fitted between adjacent joists 15 and 15. It is formed as a molded plate, and the upper surface 3 of the main body 2 is formed so as to be in close contact with the lower surface 5 of the floor plate 4, and the lower surface 6 of the main body is used for height adjustment so as to come into contact with the upper surface 9 of the large pull 7. The protrusions 10 are arranged in parallel, and the upper surface 3 of the main body can be corrected to be flush with the joist upper surface 16 by the compressive deformation of the protrusions. It is characterized in that a recess 11 for fitting the entire projection 10 is provided corresponding to the projection so that the projections can be brought into contact with each other in a substantially matched state.

The recess 11 may be provided on the upper surface 3 of the main body. In that case, the recess 11 is provided directly on the protrusion 10 or in the vicinity thereof.

(Operation) However, as shown in FIG. 7, the lower surfaces 6 and 6 of the main body are brought into contact with each other while the entire projection 10 is fitted into the recess 11 provided on the lower surface of the main body, or As shown in the figure, when the upper surface 3 of the lower heat insulating plate and the lower surface 6 of the upper heat insulating plate are brought into contact with each other with the protrusion 10 fitted in the recess 11 provided on the upper surface of the main body, The heat insulating boards for the two overlap in a substantially matched state.

The operation of the protrusion 10 will be described below. That is, when the floor heat insulating plate 1 of the present invention is fitted between the joists 15 and 15 so that it is placed on the large pull 7 at the protrusion 10 as shown in FIG. When 3 is partially projected from the joist upper surface 16,
In that part, the upper surface 3 of the floor heat insulating plate is replaced with the upper surface 9 of the large pulling board 7.
4 is compressed and deformed in such a state that the protrusion 10 part is appropriately indented (the state before the deformation is shown in FIG. 5 and the state after the deformation is shown in FIG. 6 in an enlarged manner), and FIG. As shown in FIG. 3, the entire upper surface 3 of the main body is modified to be flush with the joist upper surface 16.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

First Embodiment In FIGS. 1 to 4, a floor heat insulating plate 1 according to the present invention is wholly molded integrally with a foamed synthetic resin such as styrofoam, and on a top surface 3 of a main body 2 and a bottom surface 5 of a floor board 4. A protrusion 10 for height adjustment is formed so as to be in close contact (see FIG. 4) and the lower surface 6 of the main body can abut the upper surface 9 of the pulling bar 7 (see FIGS. 2 and 4). On the lower surface 6 of the main body, a recess 11 for fitting the protrusion 10 is provided in the vicinity of the protrusion 10.

In the present embodiment, the floor heat insulating plate 1 has a rectangular plate shape,
In addition, flat cylindrical projections 10 and elliptical recesses 11 are alternately provided on both longitudinal edge portions 12 and 13 of the lower surface 6 so that they are on the same straight line in the longitudinal direction. Further, in each side edge portion, one protrusion and one recess are arranged in a state of being close to each other, and the protrusion 10 on one side edge portion and the recess 11 on the other side edge portion face each other. It is provided.

However, as shown in FIG. 7, the two floor heat insulating plates 1 and 1 are
With the entire protrusion 10 fitted in the recess 11, the lower surfaces 6, 6 of the main body are superposed so that they come into contact with each other. 8th
The figure shows a state in which three sets of superposed bodies each including two floor heat insulating plates thus superposed are stacked. Comparing this with the case where six conventional floor heat insulating plates 1 shown in FIG. 9 are stacked, a height L corresponding to the protrusion length of the protrusion 10 multiplied by the number of stacked sheets is compared. Only the height of the stack is reduced.

Second Embodiment FIGS. 10 to 11 show a part of an embodiment other than the floor heat insulating plate 1 according to the present invention, in which both side edge portions 12 and 13 of the lower surface 6 of the main body 2 have a longitudinal direction. As they are on the same straight line,
For example, a large number of flat columnar protrusions 10 are arranged side by side at a required interval. Further, on the upper surface 3 of the main body 2, an elliptical recess 11 for fitting the projection 10 therein is provided at a position directly above the projection 10.

However, as shown in FIG. 12, the floor heat insulating plates 1 and 1 having such a structure have the upper surface 3 of the lower heat insulating plate and the upper heat insulating plate 3 with the protrusions 10 fitted in the recesses 11. The plates are sequentially stacked with the lower surface 6 of the plates in contact with each other.

Others In the floor heat insulating plate according to the present invention, the shape and size of the height adjusting protrusion 9 or its arrangement state is such that the protrusion 10 is capable of contacting the pulling upper surface 9 and the floor. When pressing the upper surface 3 of the heat insulating plate for use toward the large pulling upper surface 9
As long as 10 satisfies the condition that it can comfortably compress and deform and thereby adjust the height of the upper surface of the floor heat insulating plate,
It can be set arbitrarily. As another form of the protrusion, a triangular protrusion having a sharp tip can be exemplified.

And, the recess 11 for fitting the projection 10 is provided so that the projections are fitted in the recess so that the upper and lower floor heat insulating plates overlap in a substantially matched state, The shape of the recess 11 is set to an appropriate shape according to the shape of the protrusion. FIG. 13 shows a case where the recess 11 as a continuous groove is provided on the upper surface 3 of the main body, and FIG. 14 shows a case where the recess 11 as a groove is provided on the lower surface 6 of the main body. In the case of,
This is shown in FIG. When the recess 11 is formed as a groove in this way, the recess 11 may be formed so that both ends thereof open at both ends of the main body 2, and in particular, FIGS. One end 17 of the recess 11 as shown
Only one end of the main body 2 is open, and the other end 19 of the recess 11 is located on the other end side of the main body 2 and the outer end 20 of the protrusion 10a.
When set so as to be located directly above (Fig. 13) or to the side of the outer end 20 (Fig. 14), the floor heat insulating plate is displaced in the longitudinal direction as shown in Fig. 17, for example. Even if they are stacked in the closed state, by pushing the heat insulating plates for the floor, which are in the shifted state, toward the other end 19 of the recess (slot), the protrusion 10a at the end and the recess (slot) By contacting the other end 19 with the upper and lower floor heat insulating plates, the upper and lower floor heat insulating plates can be naturally brought into a matched state as shown in FIG.

(Effect of the Invention) Since the floor heat insulating plate of the present invention is provided with a recess for fitting a height adjusting protrusion on the lower surface or the upper surface of the main body, the protrusion is not formed during transportation. The floor heat insulating plates can be stacked in a state where they are fitted in the recesses and the upper and lower heat insulating plates are in close contact with each other. Therefore, as compared with the case of stacking floor heat insulating plates as shown in FIG. 21, the bulk of the stack can be reduced, and the transportation cost can be reduced.

Further, since the floor heat insulating plates can be stacked in a state where the protrusions are fitted in the recesses reasonably, it is possible to avoid the risk of damage to the fitted protrusions.

In addition to the above effects, the height adjusting protrusions of the floor heat insulating plate of the present invention can be appropriately compressed and deformed, so that even if the floor heat insulating plate upper surface partially projects from the joist upper surface. The height can be easily adjusted so that the entire upper surface of the floor heat insulating plate is flush with the joist upper surface, and a floor portion having excellent heat insulating properties and structural stability can be constructed.
