As described above, the floor panel used in the current hot water heating floor is manufactured in the factory in such a manner that the hot water pipe is integrally embedded in the wooden floor, and the panel is constructed. The work is brought to the site and the work of laying the floor panel and the pipe connection work for forming the hot water circulation path are performed. In the field work, the laying of flooring is a carpenter's work, and the work for forming the hot water circulation path is the work of the heating equipment shop side. It is required to be placed at the same time.

Further, connecting hot water pipes between the unit panels using joints is a complicated work, and it is necessary to provide an inspection port for the joints on the panel side.
High construction costs are required due to the amount of work and the panel structure. As shown in FIG. 17, in the case of manufacturing a product in which a plurality of unit panels are connected in a factory and bringing it into the site, it is possible to reduce the amount of pipe connecting work at the construction site. Special continuous packaging is required to transport such continuous panels from the factory to the site, and the laying work at the construction site becomes difficult. Further, the exposed portion of the pipe is likely to be scratched or unnecessarily bent, resulting in a case where the entire panel is defective.

Further, in order to lengthen the hot water path in the unit panel as described above, a wide floor material is usually used, and a concave groove having a plurality of bent portions is processed therein.
This grooving is extremely complicated and causes a cost increase. Further, as shown in FIG. 17, it takes a long time to bury a hot water pipe in a groove processed into a complicated path and to fix it stably there.
Improvement is required.

An object of the present invention is to eliminate the above-mentioned inconveniences of the heating floor and the construction method thereof by the current hot water circulation system, and more specifically, the floor material which is the work of the carpenter side. Installation method of hot water heating floor that enables installation work and connection of hot water pipes, which are operations on the heating equipment store side, and installation work to be performed as separate processes, thereby reducing construction costs. Is to get.

Another object of the present invention is to simplify the locus of the concave groove for accommodation of the hot water pipe formed on the back surface of the floor material,
Therefore, it is to obtain a hot water heating floor construction method capable of reducing the manufacturing cost of the floor material.

Still another object of the present invention is to provide a hot water heating floor construction method in which the number of hot water pipe connections is reduced, thereby simplifying the construction work and reducing the probability of water leakage. It is in.

Still another object of the present invention is to simplify the construction method so that the construction can be carried out at low cost, the hot water pipe can be easily arranged, and the hot water pipe is damaged. By avoiding a large amount, even if the floor material or hot water circulation system is damaged or abnormal,
The purpose is to obtain a hot water heating floor in which only the hot water pipe can be easily replaced and repaired.

[0014]

A method of constructing a hot water heating floor according to the present invention for solving the above-mentioned problems is basically such that a concave groove corresponding to the shape of a circulation path of a hot water pipe is formed on the back surface. Arranging the plurality of floor materials on the floor base, removing a part of the plurality of arranging floor materials, hot water through a groove formed in the floor material arranged adjacent to the removed floor materials A floor material other than the floor material to be removed, and a step of continuously arranging the water pipe, and a step of rearranging the removed floor material to the original position after the hot water pipe is completely arranged. As a feature, the construction is performed using a floor material having a back surface sheet that covers at least the concave groove portion formed on the back surface.

Preferably, as the floor material other than the above-mentioned floor material to be removed, a floor material further having a thin second groove for taking in an excessive adhesive along the concave groove portion formed on the back surface is used. To use.

In the method for constructing a hot water heating floor according to the present invention, a plurality of floor materials in which concave grooves are cut in a shape corresponding to the piping pattern of the hot water pipe to be arranged on the floor substrate are manufactured in a factory, The floor material is delivered to the construction site as it is.
At the construction site, among the plurality of floor materials, a floor material having a back sheet that covers at least the above-described groove portion formed on the back surface is assembled over a required number of stages so that each groove is continuous, preferably Is fixedly placed on the floor base using nailing or adhesive of the actual part formed around it.

Next, a floor material having a curved (for example, U-shaped) concave groove on the back surface (that is, a floor material to be removed) is fixedly arranged at the end of the concave groove. It is arranged so as to be continuous with the end of the groove. By arranging all the floor materials on the floor base material in this way, one continuous circulation path is formed on the back surface of the placed floor material, and at that time, the floor material arrangement which is the work of the carpenter side is arranged. The work ends.

Next, as work on the side of the heating equipment store, the work of connecting and arranging the hot water pipe is performed. First, only the floor material having the curved concave groove arranged earlier is removed, and the hot water pipe is inserted from one end to the other end in the concave groove formed in the adjacent floor material. Since this floor material is mainly formed with a linear groove, and at least the groove portion formed on the back surface is covered with a back sheet, the adhesive used for adhesion to the floor base surface is a groove groove. The hot water pipe can be inserted into the groove without any obstacle. Even if foreign matter such as nails remains on the floor substrate, the back sheet can prevent the foreign matter from entering the groove,
It is possible to prevent the hot water pipe from being damaged. further,
When using a flooring material further formed with a thin second groove along the concave groove formed on the back surface to take in the excess adhesive, for example, when the adhesive is applied to a non-uniform thickness The raised portion (excess adhesive) can be released into the second groove. As a result, the adhesion is unstable
To prevent it from becoming uneven or the adhesive surface becoming uneven
be able to. Furthermore, since the adhesive surface becomes flat,
Due to the swelling of the adhesive, the back sheet will be in the groove
If the back sheet is peeled off when pushed in,
It is possible to avoid inconvenience in inserting the
It

Upon insertion, one hot water pipe may be bent in a U shape and inserted into two recessed grooves of one floor material at the same time. After inserting the hot water pipes into all the grooves, the end parts of the hot water pipes extending from the end parts of the floor material are connected via an appropriate connecting tool so as to form one continuous circulation path. Connecting.

At this time, it is preferable to use a mount having a trace substantially the same as the trace of the concave groove formed on the back surface of the floor that was previously removed, and place the mount at the position of the removed floor. . Then, the shape of the bent portion or the connecting portion of the hot water pipe extending from the end portion of the floor material is bent or connected while adjusting the posture so as to follow the locus drawn on the mount.

After the above work, the floor material previously removed is relocated to the original position. At that time, it may be fixed by an adhesive or nailing, or may be fixed in a detachable form by means such as screwing. By using the above-mentioned mount, the locus of the pipe for hot water is a locus that substantially coincides with the locus of the concave groove formed on the back surface, and it is easy to attach the floor material after the piping. The construction of the heating floor is completed by connecting both ends of the hot water circulation path thus formed to the hot water generating source side, as in the case of the conventional hot water heating floor.

Preferably, as the floor material to be removed, one having a tape for removal attached to one or several locations around the floor material is used, and the floor material to be removed is placed at the time of arranging the floor material as a work on the carpenter's side. Leave the end of the tape exposed from the surface. By doing so, the worker on the heating equipment store side can easily remove the floor material. After the disposition of the hot water pipe, the flooring material is repositioned to its original position with the tape for removal removed.

Preferably, in the flooring material used in the present invention, a metal foil as a soaking plate is arranged as an intermediate layer. This prevents heating only in the vicinity of the hot water pipe and enhances the soaking effect.

As can be seen from the above description, according to the hot water type heating floor construction method of the present invention, the so-called floor material construction for arranging the floor material and the heating construction for forming the hot water circulation system are completely independent steps. The floor material can be constructed in the same manner as the ordinary flooring floor construction. Therefore, work efficiency is improved and construction cost is reduced. In addition, floor materials can be divided into those that mainly have linear grooves and those that have curved grooves, and those that have curved grooves are Since it is a part of the total number, the work of forming the groove as the whole floor material is reduced, and the manufacturing cost is reduced.

Further, since the back sheet is arranged so as to cover at least the groove portion mainly on the back surface of the flooring material having the linear groove, it is easy to insert the hot water pipe,
Moreover, the hot water pipe is not damaged by the intrusion of foreign matter.

The hot water circulation system may be one circulation system for the entire floor surface. When the floor area is large, a plurality of hot water circulation systems are formed and hot water is circulated for each system. Good. Furthermore, the hot water circulation system may be provided on the entire surface of the floor to be constructed, or may be provided partially. Also,
As in the conventional case, a normal floor material may be arranged as a border panel around the periphery, if necessary.

As can be seen from the above description, the longitudinal shape of the concave groove formed in the flooring material having the back sheet according to the present invention is such that one side of the concave groove is formed after the flooring material is placed on the floor base. Any shape may be used as long as the hot water pipe can be inserted to the other end, and the groove is preferably a linear groove, but is not limited thereto. For example, the groove may be curved with a large curvature in the longitudinal direction of the floor material. Good. Therefore, in the present invention, the term "mainly" in the case of "mainly a straight line portion of a pipe for hot water" or "mainly a linear groove",
It is used not only as a straight line but also as a shape that curves with such a large curvature.

And the second terminal floor material Bb on the left side. In this example, the terminal flooring material B is made of the same material as the flooring material A having the back sheet, that is, a material having a three-layer structure including the front surface side plywood 1a, the aluminum foil 3, and the back surface side plywood 1b. The width and the thickness are at least the same.

As shown in the figure, a large number of notches 6 are formed in the central portion of the back side plywood 1b, which are orthogonal to the longitudinal direction.
Further, in the vicinity of the right side and the left side, there are recessed strips 7 _{1 to} 7 having substantially the same size as the recessed groove 2 formed in the floor material A having the back sheet.
₄ and 8 ₁ to 8 ₄ are formed on the side surface on the short side thereof with the ends open and at the same intervals as the four concave grooves 2. And on the right side, the concave lines 7 ₁ and 7 ₂ and the concave lines 7 ₃ and 7
₄ communicates with each other to form U-shaped concave grooves 7a and 7b, and on the left side, the concave lines 8 ₂ and 8 ₃ communicate with each other to form a U-shaped concave groove 8a. Further, the upper and lower recessed lines 8 ₁ and 8 ₄ are the third recesses formed orthogonally to the longitudinal direction slightly inward of the U-shaped bent portion of the U-shaped recessed groove 8a. While reaching the groove 9, the groove is branched toward the side face side in the longitudinal direction on the way to form concave grooves 8b and 8c that are substantially C-shaped as a whole. Further, on the four side surfaces of the back side plywood 1b, the male material 5a and female fruit 5b formed on the four circumferences of the floor material A having the back sheet can be continuously joined to the floor material A without colliding with each other. Inward cutout 1
1 is formed. Further, on the back surface of the short side, two tapes 12 for removal are attached respectively with a length extending beyond the front side plywood 1a as well shown in FIG. 4c.

FIG. 5 shows a border floor material C. The border floor material C may be the same as the wooden floor material used for the conventional flooring floor, and in this example, like the floor material A, it has the front surface side plywood 1a and the back surface side plywood 1b, and the back surface. A male seed 2a and a female seed 2b are formed around the side plywood 1b, and at least the width and the thickness are the same.

In the hot water heating floor construction method according to the present invention, the required number of floor materials A, B and C for the floor surface to be constructed are manufactured in the factory and brought into the construction site. , They are placed on the floor. The first terminal flooring material Ba and the second terminal flooring material Bb may be manufactured separately from the beginning in a factory.

A case of constructing a heating floor having the shape shown in FIG. 1 using these floor materials will be described below. First, the floor materials A, B, and C are placed on the floor surface (on the floor substrate) by the procedure shown in FIGS.
Is located in. That is, first, three border floor materials C are arranged in a row along the upper side 51 of the floor surface 50 (FIG. 6).
a). At the time of arrangement, as in the case of the conventional flooring floor, an adhesive agent is used or nailing or the like is performed on the female part as needed to fix it on the floor surface. Prior to arranging the floor material, as in the case of the conventional heating floor construction, appropriate heat insulating treatment and soaking treatment may be performed on the floor surface (floor base). Further, similarly to the conventional construction method, the installation work of the outward piping for introducing hot water from a hot water generation source (not shown) and the return piping to the hot water generation source is also performed.

Next, the terminal flooring material B shown in FIG. 4 is divided into two parts according to the size of the floor surface, and is divided into a first terminal flooring material Ba and a second terminal flooring material Bb. The separated first terminal flooring material Ba is placed in contact with the right side of the floor surface, and the open ends of the U-shaped concave grooves 7a, 7b on the back surface are directed inward (FIG. 6b). . At this time, the first terminal flooring material Ba does not have to be fixed to the floor base only by placing it on the floor surface, but in consideration of the stability of the work, it is temporarily fixed with an adhesive or a temporary fixing nail. You may fix it. In any case, the tip of the tape 12 for removal attached to the back surface should be exposed on the front surface side.

Since a large number of cuts 6 are formed in the central portion of the back surface side plywood 1b, the terminal materials after separation are compared with each other in the portion on the side of the side when placed on the floor surface. It is easier to bend. Therefore, even when the skirting board is attached to the wall surface, it is easy to attach and detach it to the floor surface.

Next, three floor materials A having back sheets are placed in contact with the placed first terminal floor material Ba. that time,
As shown in FIGS. 1 and 6c, a floor material Aa having a back sheet having a length shorter than that of the floor material A having a unit length is also used according to the widthwise length of the floor surface. The floor material Aa having this back sheet may be obtained by cutting at the construction site, or may be manufactured in the factory from the beginning. As with the border floor material C, the floor materials A and Aa having the back sheet are fixed to the floor surface by using an adhesive or by nailing the female part as needed.

The application of the adhesive may be performed in a streak pattern on the floor base material or on the back surface of the floor materials A and Aa. When applying an adhesive to the back surface of the floor materials A and Aa,
Preferably, it is applied to a place excluding the back sheet 4. In any case, when there is unevenness in the applied thickness of the adhesive, by sliding the floor materials A and Aa while pressing the floor materials A and Aa at the time of placement, the excess adhesive enters the thin second groove 2a. Therefore, a flat adhesive surface can be obtained. As a result, the backside of
The sheet is pushed into the groove and the back sheet peels off.
May occur or the effective cross-sectional area of the groove may be reduced,
It is possible to avoid inconvenience in inserting the ip.
It

Next, the separated second terminal floor material Bb.
Is arranged between the end of the floor material A having the back sheet and the left side of the floor surface, and the open end side of the U-shaped concave groove 8a on the bottom surface is directed inward. If necessary, cut a part along the notch 6 to adjust the length. At this time, similarly to the first terminal floor material Ba, the second terminal floor material B
b does not have to be adhesively fixed to the floor base, but may be temporarily fixed with an adhesive, a temporary fixing nail, or the like. In any case, the removal tape 12 attached to the back surface
Leave the tip of the to appear on the front side.

Hereinafter, this work is required a required number of times (1 in this example).
(0 times), and finally, three border floor materials C are fixed along the lower side of the floor surface 50, and the floor material construction step of the shape shown in FIG. 1 is completed.

Next, heating is carried out. The heating work is done by the workers of the heating equipment store, not the carpenter. First, the operator removes the first terminal floor material Ba and the second terminal floor material Bb by manually pulling up the tape 12 for removal protruding on the surface as shown in FIG. Next, as shown in FIG. 8, a hot water pipe P such as a cross-linked polyethylene pipe cut into a predetermined length is passed through each groove 2 formed on the back surface of the floor material A having a back sheet,
Penetrate from one end to the other. Since the concave groove 2 of the floor material A is covered with the back sheet 4, the floor material A is placed in the concave groove 2.
The adhesive used during the bonding of No. 1 does not enter, and the hot water pipe P smoothly passes through the concave groove 2.

Preferably, as shown in FIG. 9, the length of one hot water pipe P is slightly longer than twice the length LL of the floor material A having the back sheet fixed to the floor surface. Bend it in a U shape and insert it into the two grooves from the right end to the left end. Thereafter, similarly, one hot water pipe P is inserted into the two adjacent concave grooves. As a result, the U-shaped bent portion Pu of the hot water pipe P is exposed at the location of the first terminal flooring material Ba that was previously removed, and both end portions thereof are exposed at the location of the second terminal flooring material Bb. Pe is exposed.

After the hot water pipes P are inserted into the recessed grooves 2 formed in the floor material A having all the back sheets in this way, the hot water pipes P end are formed so as to form one circulation path. Connect club members. 2 according to the size of the floor
You may connect so that the above circulation path may be formed. Figure 10
Is an example of a case where one hot water circulation path is configured by a group of hot water pipes P inserted in a floor material A having a back sheet for five steps, and the hot water pipes P arranged at the highest position in the drawing are shown.
One end P _e1 is connected to a hot water supply side of a joint box G separately arranged on the floor via a lead-in pipe P _g1 , and the other end P _e2 is a lower-ranking hot water pipe P. _Is connected to one end P _e3 . Further, the other end of the hot water pipe P is connected to one end of the hot water pipe P located at a lower position in this order, and the hot water pipe P is located at a lower position of the floor material A having the fifth back sheet. The other end P _ex side of the hot water pipe P is connected to the joint box G via the lead-in pipe P _g2, thereby forming one hot water circulation path.

After forming the hot water circulation path in this way, the first terminal floor material Ba and the second terminal material previously removed are
The removal tape 12 is removed from the terminal floor material Bb, and the floor material is fixed in its original position by an adhesive or by nailing the pseudo groove 1c portion as needed, thereby performing heating work. The process ends.

The above-mentioned first terminal flooring material Ba and second
U-shaped groove 7a formed on the back surface of the terminal floor material Bb,
The shapes of 7b and 8a and the shapes of the substantially U-shaped concave grooves 8b and 8c are the same as those in the case of constructing the hot water circulation path as described above.
Corresponding to the loci of the hot water pipe P on the terminal flooring material Ba side and the second terminal flooring material Bb side,
The third concave groove 9 formed on the back surface of the second terminal floor material Bb corresponds to the locus of the lead-in pipe P _g1 or P _g2 . Therefore, the locus of the U-shaped portion and the locus of the connecting portion of the hot water pipe P are determined so as to match the shapes of the recessed grooves when the circulation path is formed, and the locations are matched so that the first terminal The floor material Ba and the second terminal floor material Bb can be easily attached after the circulation path is formed.

At the time of actual heating, the locus of the U-shaped portion and the locus of the connecting portion of the hot water pipe P are traced to the first terminal floor material B.
It is not easy to advance the work by matching the shapes of the concave grooves formed on the back surface of the a and the second terminal floor material Bb. Figure 1
Reference numeral 1 shows an example of a mount 60 used for easily and surely performing the work. On the right side of this mount 60 is the first
U-shaped grooves 7a, 7 formed on the back surface of the terminal flooring material Ba
The locus of b is transferred as it is as a printed pattern 60a, and on the left side is a U-shaped concave groove 8a formed on the back surface of the second terminal floor material Bb, substantially groove-shaped concave grooves 8b and 8c, and a third groove. A mark 63a indicating the length of the groove 9 trace and the length at which the two ends Pe of the hot water pipe P to be connected to each other should be cut,
63b is printed.

After removing the first terminal flooring material Ba, the operator mounts the backing sheet 60 on the flooring material A having the back sheet having the front end fixed on the printed pattern 60a side as shown in FIG. 12a. It is placed on the floor so as to match the four concave grooves 2 of. In addition, after removing the second terminal flooring Bb, FIG.
As shown in FIG. 4, the backing sheet 60 is provided with four recessed grooves 2 of the floor material A having a back sheet on which the front end on the printed pattern 60b side is fixed.
Place it on the floor to match.

In this state, the two hot water pipes P bent in a U shape are inserted into the four recessed grooves 2 of the floor material A having the back sheet, and the U-shaped portion 60u is transferred to the mount 60. The posture is corrected so as to match the printed pattern 60a. If necessary, the mount 60 is removed, and as shown in FIG. 12b, the work is completed by fixing the first terminal flooring material Ba. Hereinafter, this work is repeated.

On the side of the second terminal floor material Bb, first, the uppermost end P _e1 of the hot water pipe P is straightened and cut at the printed pattern portion corresponding to the third groove 9. And there through the bend joint S ₁ the lead-in pipe P _g1
Connect to. Next, the lower end P _e2 is cut along the pipe cut line 63a, the lower end P _e3 is cut along the pipe cut line 63b, and the linear joint S ₂ is attached thereto. (Fig. 13b). Then, the end portion P _e2 and the end portion P _e3 are inserted into the joint and finely adjusted so as to be the same as the printed trajectory, and are connected (shown by the dotted line in FIG. 13b). If necessary, the mount 60 is removed, and the second terminal floor material Bb is fixed in the same manner as the first terminal floor material Ba side, and the operation is completed.
Hereinafter, this work is repeated.

As described above, by using the mount 60, the posture control at the bent portion or the connection portion of the hot water pipe P becomes easy and reliable, and the end floor material removed after the circulation path of the hot water pipe is removed. It can be easily fixed on the floor. As the mount, one having a heat equalizing plate attached to the back side may be used, and in that case, the mount is left on the floor as it is without being removed.

According to the present invention, it becomes possible to completely separate the work process on the carpenter side, which is the work for arranging the floor material, and the work process on the heating equipment store, which is the work for laying the hot water pipe, Since the degree of freedom in work management is increased, the cost of construction can be reduced as a result.

Further, the floor material only has a recess groove formed on its back surface and is covered with a back surface sheet, and does not require incorporation of a hot water pipe, so that the cost can be reduced. Further, as in the case of ordinary flooring materials, inventory management and shipment as finished products facilitates construction management.

Furthermore, this is a work procedure in which a hot water pipe is inserted after the floor material has been installed, and there is no possibility that the pipe will be damaged during transportation and the entire heating floor material will become defective as in the conventional case. Even if the hot water pipe is damaged during construction, only the damaged hot water pipe needs to be replaced, which facilitates maintenance and reduces maintenance costs.

Further, since the back sheet is arranged at least on the back surface of the flooring material having the recessed groove so as to cover the recessed groove, it is easy to insert the hot water pipe, and the foreign matter invades the hot water. It also avoids damage to the pipe. It
