Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a joint-equipped heat insulating plate on which concrete or the like is placed on the surface when a concrete floor or the like is provided in a building.

Technical Background of the Invention and Problems Thereof For example, in the case of forming a concrete floor on the roof of a building, as shown in FIG. 9, a waterproof layer 2 is formed on a roof slab 1 and the waterproof layer 2 is formed. A plurality of heat insulating plates 3 are laid in a flat shape on the above, and the pressing concrete 4 is placed on the surface of the heat insulating plate 3. Then, before the concrete for pressing 4 is driven into the surface of the heat insulating plate 3, rod-shaped joint materials 5 are installed on the surface of the heat insulating plate 3 at appropriate intervals. The joint material 5 is made of an elastic material and absorbs these strains when the concrete 4 placed between the joint materials 5 is thermally expanded or contracted due to a change in the surrounding environment,
This is for preventing the concrete 4 from cracking.

However, such joint material 5 is
Before placing, the adhesives, the mortar, or the fixing pins are used to attach each one on the surface of the heat insulating material 3 one by one, so that there is a problem that the workability is very poor. In particular, when the joint material 5 is fixed to the surface of the heat insulating plate 3 with an adhesive or the like, the joint material 5 is easily peeled off, and there is a possibility that the joint material 5 is washed by the concrete during the placing of the concrete 4. It was Further, in order to prevent the joint material 5 from being peeled off from the heat insulating plate 3, a hose pier for preventing a concrete placing hose from colliding with the joint material 5 is provided, or a worker's foot is jointed with the joint material. There was a problem that we had to be careful not to collide with 5.

In order to solve such a problem, it has been proposed that the joint material 5 and the heat insulating plate 3 are integrally formed. According to such a heat insulating plate, it is not necessary to position and fix the joint material 5, and workability is greatly improved. However, the heat insulating plate 3 is integrally formed of the relatively expensive joint material 5 which requires elasticity. Due to the molding, there is a new problem that the cost of the heat insulating plate becomes high. Further, since the joint material 5 and the heat insulating plate 3 are inseparable from each other, the stacking efficiency during storage or transportation of the joint material 5 is poor, and this also causes a problem of high cost.

OBJECT OF THE INVENTION The present invention has been made in order to solve such a problem, and on the surface of a heat insulating plate on which concrete or the like is cast, the surface of the heat insulating plate before the concrete or the like is cast. An object of the present invention is to provide a heat insulating plate with a joint material which can easily and firmly position and fix the joint material and which is inexpensive in manufacturing cost and storage or transportation cost.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a heat insulating plate having a surface such as concrete for pressing, in which a pattern hole is formed on the surface of the heat insulating plate, and the pattern hole is appropriately deformed and restored. It is characterized in that a handle formed on a rod-shaped joint material having a force is fitted.

In such a heat insulating plate with joint material, the joint material and the heat insulating plate can be separately provided at the time of storage or transportation thereof, so that the efficiency of stacking the heat insulating plates is good. In addition, when placing concrete such as presser foot on the surface of the heat insulating plate, simply fit the handle holes of the joint material in accordance with the handle holes formed on the surface of the heat insulating plate. The matching and fixed mounting are completed at the same time, and the workability is greatly improved compared to the conventional one. Further, since the joint material and the heat insulating plate are not integrally molded, it is not necessary to make the material of the heat insulating plate the same as the material of the relatively expensive joint material, and the manufacturing cost does not increase.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below based on the embodiments shown in the drawings.

FIG. 1 is a cross-sectional view showing a usage state of a heat insulating plate with joint material according to an embodiment of the present invention, and FIG. 2 is a perspective view in which the joint material of the heat insulating plate with joint material according to the embodiment is omitted. The same members as those shown in FIG. 9 are designated by the same reference numerals.

The heat insulating plate 10 according to the present embodiment shown in FIGS. 1 and 2 is laid flat on a waterproof layer provided on the roof slab 1 when a concrete floor is provided on the roof of a building,
The pressing concrete 4 is placed so as to cover the surface thereof. Since the pressing concrete 4 may thermally expand or contract due to changes in the surrounding environment and cause cracks or the like on the surface, it is necessary to partition the concrete 4 with rod-shaped joint materials at appropriate intervals. The joint material is generally formed of an elastic material so as to absorb the heat of the concrete 4 and the like.

As shown in FIG. 1, the joint material 11 according to this embodiment has a handle 12 at the bottom thereof. The handle 12 is formed continuously along the longitudinal direction of the rod-shaped joint material 11, and can be fitted into a handle hole 13 formed in the heat insulating plate 12 which will be described later. The joint material 11 is formed into a rod shape by using foamed polypropylene or the like having appropriate strength and deformation stability, and the fall prevention projections 14 are formed on both upper sides of the handle 12 along the longitudinal direction thereof. Also,
A cover 15 covers the head of the joint material 11.

The heat insulating plate 10 according to the present embodiment is formed into a plate shape with relatively inexpensive foamed styrene or the like, and a handle hole 13 is continuously formed in the longitudinal direction at substantially the center of the surface thereof. The vertical cross-sectional shape of the handle hole 13 is substantially the same quadrangular shape as the handle 12 formed on the joint material 11, and the handle 12 is closely fitted into the handle hole 13. The handle hole 13 and the heat insulating plate 10 may be integrally formed, but may be formed by post-processing.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be modified in various ways.

For example, the handle holes 13 formed in the heat insulating plate 10 do not necessarily have to be formed continuously along the longitudinal direction of the joint material 11, and
As shown in the figure, the handle holes 13a may be intermittent. In the case of this embodiment, the handle 12 formed on the joint material 11 also has the handle hole 13
It needs to be formed intermittently according to a.

Further, in the case of such an intermittent handle hole, various shapes are conceivable as the cross-sectional shape of this handle hole, as shown in FIGS. Any shape such as a shape having However, it is necessary to change the cross-sectional shape of the handle 13 formed on the joint material 11 in consideration of fitting adaptability in accordance with the cross-sectional shape of these handle holes.

Further, as shown in FIG. 3, a large number of irregularities 16 may be formed on the back surface of the heat insulating plate 10. Further, when the plurality of heat insulating plates 10 are laid in a planar shape, a joining part 17 may be formed at a joint part which is a part of the peripheral edge of the heat insulating plates 10 so that the heat insulating plates 10 can be easily joined together. good.

The cross-sectional shape of the handle holes 13 and 13a formed in the heat insulating plate 10 is
The shape is not limited to a quadrangle, and may be a trapezoidal shape or another shape as shown in FIG.

Further, the handle holes 13 and 13a formed in the heat insulating plate 10 may be formed in the joint portion 18 between the heat insulating plates 10 as shown in FIG. In the case of this embodiment, it is convenient because the joint material 11 prevents concrete from trying to enter the joint portion 18 when concrete is cast on the back surface of the heat insulating plate 10.

Further, as shown in FIGS. 7A and 7B, the heat insulating plate 10
The handle hole 13b formed in the above may penetrate the front and back surfaces of the heat insulating plate 10. In particular, in FIG. 1B, since the unevenness 16 is formed on the back surface of the heat insulating plate 10, the handle 12 formed on the bottom of the joint material 11 slightly projects from the back surface of the heat insulating plate 10. According to such an embodiment, the fitting of the handle 12 of the joint material 11 and the handle hole 13b of the heat insulating plate 10 becomes stronger, the joint material 11 arrives, and at that time, the surroundings of the handle hole 13b. There is almost no risk of damaging the heat insulating plate 10.

As the cross-sectional shape of the joint material 11 attached to the heat insulating plate 10, various shapes can be considered, for example, as shown in FIGS. 8 (A) to (D). (A), (B),
Although (D) has a protrusion 14 for preventing falls, (C) in FIG.
Shows that it does not have this.

Further, as shown in FIG. 6E, only the handle 12a formed at the bottom of the joint material 11 may be made of a heat insulating material (for example, foamed plastic) unlike the other portions. Then, the handle holes 13, 13a, 13b formed in the heat insulating plate 10
This handle 12a can supplement the heat insulation defect corresponding to.

EFFECTS OF THE INVENTION As described above, according to the present invention, since the joint material can be freely fitted to the heat insulating plate, the joint material can be easily and firmly fixed to the surface of the heat insulating plate before the concrete is poured. In addition, since the heat insulating plate is separate from the joint material, it is convenient for storage and transportation of the heat insulating plate, and the manufacturing cost of such heat insulating plate does not increase. It has an excellent effect.
