Description

  The present invention relates to a fall prevention tool for a floor heating radiator joint (hereinafter also simply referred to as a “joint”) and a method for constructing a floor heating apparatus.

  As shown in FIGS. 1 to 3, the floor heating apparatus is constructed by connecting a floor heating radiator 2 placed on the base material 1 and a heat source machine (not shown), for example. And the flooring 3 is constructed on the floor heating radiator 2, and the floor heating radiator 2 is composed of a plurality of floor heating panels 20a and 20b. In each of the floor heating panels 20a and 20b, The internal pipes 2a, 2b, 2c, and 2d are built in, and hot water heated by a heat source machine (not shown) is introduced into the floor heating panel 20a from the internal pipe 2a, for example, and from the internal pipe 2b to the floor heating panel It is discharged from 20a.

  For example, the internal pipe 2b and the internal pipe 2d are connected by a bamboo joint (see FIG. 4C), the internal pipe 2a and the hot water supply external pipe (not shown), the internal pipe 2c and the hot water discharge external pipe (illustration). (Not shown) are connected to each other by elbow joints (see FIG. 4 (b)), the hot water introduced from the internal pipe 2a circulates in the floor heating panel 20a, and passes through the internal pipe 2b and the internal pipe 2d. It is introduced into the heating panel 20b, finally discharged from the internal pipe 2c, transferred to a heat source machine (not shown) through the external pipe at the bottom of the base material 1, and reheated. Hereinafter, this case is referred to as “construction example 1”.

  For example, the internal pipe 2a and the internal pipe 2c are connected to an external pipe for hot water supply (not shown) using a cheese joint (see FIG. 4A), and the cheese joint (see FIG. 4A) is also used. It is also possible to connect the internal pipe 2b and the internal pipe 2d with an external pipe (not shown) for discharging hot water. In this case, after the warm water heated by the heat source device (not shown) is introduced into the floor heating panel 20a and the floor heating panel 20b from the internal pipe 2a and the internal pipe 2c, respectively, and circulates in both floor heating panels. These are discharged from the internal pipe 2b and the internal pipe 2d, respectively, are transferred to a heat source machine (not shown) through the external pipe at the bottom of the base material 1 and reheated as in the construction example 1. Hereinafter, this case is referred to as “construction example 2”.

  As shown to Fig.4 (a)-(c), all the couplings have the horizontal part 4a, and have the connection part 4c with internal piping in the horizontal part 4a. Moreover, as shown to Fig.4 (a) and FIG.4 (b), a cheese joint and an elbow joint have the vertical part 4b, and have the connection part 4d with external piping in the lower part.

  As shown in FIG. 5, in the construction method of a normal floor heating apparatus, piping holes 1a are provided in the base material 1 in advance so as to correspond to the respective joints 4, and the vertical portions 4b of the joints 4 are provided. By connecting the internal pipe (not shown) in the floor heating radiator 2 to the connection part 4c of the joint 4 and inserting the external pipes 5a and 5b to the connection part 4d of the joint 4 while being inserted into the pipe hole 1a. (For example, see FIG. 4 of Patent Document 1, FIG. 14 of Patent Document 2, FIG. 6 of Patent Document 3, and the like). Usually, the joint connecting portion 4d has an outer diameter of about 20 mm, and the base material is provided with a piping hole 1a having an inner diameter of about 35 mm.

  In the construction method shown in FIG. 5, basically, two piping holes 1 a are provided, and the vertical portions 4 b of the two joints 4 are inserted into the respective piping holes 1 a so as to protrude below the base material 1. In the state, it is necessary to connect the external pipes 5a and 5b to the connecting portion 4d. For this reason, it is necessary for the worker to work in a state of being submerged under the base material 1. In the case of renovating an existing property, it is necessary to redo the groundwork, such as discarding the existing floor.

  Here, at least two of the joints for connecting the hot water supply pipe and the joint for connecting the hot water discharge pipe are necessary for the joint, but as shown in FIG. Instead of drilling pipe holes corresponding to each of the joints, one large pipe hole (size that allows human fists to be taken in and out. Internal diameter of about 50 to 90 mm, typically about 80 mm) is provided. It is preferable to adopt a construction method in which two joints and two external pipes are connected to each other. Hereinafter, this construction method will be described.

In the construction method shown in FIG. 6, for example, a pipe hole 1 a is made in advance in the base material, the external pipe 5 is inserted into the base material from above, and the heat source machine (not shown) passes through the space below the base material. Send and connect. And as shown in FIG. 7, the external piping 5 is hold | maintained by the upper part of the base material 1 in the state connected to the coupling (cheese coupling in the example shown to a figure) 4, and as shown in FIG. It is connected to internal piping (not shown) in the radiator 2. As shown in FIG. 7, a heat shield tube 6 is usually wound around the vertical portion of the joint. In this construction method, one piping hole is generally provided for approximately 6.6 m ² (corresponding to four 3 × 6 floor heating panels). Even when the floor heating floor has a large construction area and two or more piping holes are provided, it is necessary that the outer shells of each hole be separated by 40 mm or more.

  If this construction method is adopted, there is an advantage that the floor heating floor can be constructed even when the floor heating floor is constructed at the time of renovation, even in the case where there is no space for the worker to crawl under the base material.

  However, in this construction method, as shown in FIG. 7, even in a cheese joint having a relatively long horizontal portion, the length of the horizontal portion of the joint 4 is approximately the same as the inner diameter of the pipe hole 1a. The joint 4 may fall from the piping hole in the middle. Further, as shown in FIG. 8, after all the pipes are connected and the construction is completed, the joint 4 is in a state of little support at the upper part of the pipe hole 1a. (Omitted).

  The present invention provides a relatively large piping hole in the base material, and the joint is connected at the time of construction in a construction method in which two internal pipes and two external pipes are connected by two joints through the pipe holes. It aims at providing the construction method of the fall prevention tool of the joint for floor heating radiators, and a floor heating apparatus which prevents falling to a piping hole.

  As shown in FIGS. 1 to 4 and FIGS. 6 to 8, the fall prevention device for the floor heating radiator joint according to the present invention is provided with a heat source machine (not shown), the floor heating radiator 2, and the piping hole 1 a. A base material 1, internal pipes 2 a, 2 b, 2 c, 2 d for transferring hot water into the floor heating radiator 2, an external pipe 5 a for supplying hot water from the heat source unit to the floor heating radiator 2, Hot water discharge external pipe 5b for transferring warm water from the heating radiator 2 to the heat source unit, and hot water supply external pipe 5a and internal pipes 2a, 2b, 2c, 2d at the position of the pipe hole 1a (2a in the construction example 1, construction) In Example 2, the first joint 40a connecting 2a and 2c), and the warm water discharge external pipe 5b and the internal pipes 2a, 2b, 2c, and 2d (2c in the construction example 1, 2b and 2d in the construction example 2) and A floor heating device having a second joint 40b for connecting In a jig to prevent the 該継 hand falls into the piping hole.

  And as shown to Fig.9 (a)-(h), as for the fall prevention tools 7a-7h of the joint which concerns on this invention, thickness is 1 mm or less, and length and width are larger than the diameter of the piping hole 1a. It is a sheet-like thing, and has the hole 70a-70f or notch 71a-71g of the magnitude | size which the 1st coupling 40a and the 2nd coupling 40b do not fall. 9 (a), (d) and (g) are holes only, FIGS. 9 (b), (c), (f) and (h) are notches only, and FIG. 9 (e) is a hole. The example which has both and a notch is shown. These sheet-like objects 7a to 7h are placed on the upper part of the piping hole 1a of the base material, and are used by being attached to the base material with a tape or the like.

  If the thickness of the sheet-like object as a joint fall prevention device exceeds 1 mm, the floor heating radiator 2 cannot be installed horizontally due to the level difference, and the walking feeling when the floor heating floor is installed is felt. Deteriorate. For this reason, it is preferable that thickness is thin in the range which has intensity | strength sufficient to support a coupling. The material of the sheet-like material is not particularly limited as long as it has sufficient strength to support the joint even with a thickness of 1 mm or less. For example, known materials such as a resin sheet, a metal sheet, and paper can be used. Among these, it is preferable to use a resin sheet from the viewpoint of workability and cost.

  As shown in FIGS. 9 (a), (d), (e), and (g), the holes 70a to 70f pass through the vertical portions of the first joint 40a and the second joint 40b. It is preferable that the size is such that the horizontal portion of the two joints 40b does not pass. Moreover, as shown to FIG.9 (b), (c), (e), (f), (h), although the notches 71a-71g let the perpendicular | vertical part of the 1st coupling 40a and the 2nd coupling 40b pass. The first joint 40a and the second joint 40b are preferably sized so as not to pass through the horizontal portion. This is because the vertical portions of the first joint 40a and the second joint 40b need to be connected to the external pipe below the base material, so that the holes and notches are preferably passed therethrough. Since the horizontal part of 40a and the 2nd joint 40b can prevent the fall of a joint when it catches in the circumference | surroundings of a hole or a notch, it is preferable not to let this pass.

  Here, as shown in FIGS. 4 (a) and 4 (b), the vertical portion 4b of the joint has a constant diameter portion and a maximum diameter portion having the largest diameter at the lowermost portion. In the case of a notch, it is sufficient that the width is larger than the diameter of the fixed portion of the vertical portion 4b, but in the case of a hole, the diameter needs to be larger than the maximum diameter portion of the vertical portion 4b. However, in the case of providing a slit to be described later, it is only necessary that the width is larger than the diameter of the fixed portion of the vertical portion 4b as in the case of the notch.

  On the other hand, as shown to Fig.4 (a), the length of the horizontal part 4a of a cheese joint is the space | interval of the connection parts 4c in both sides, and as shown in FIG.4 (b), the horizontal part of an elbow joint The length 4a is the distance between the top of the head and the connecting portion 4c. Therefore, the size that does not pass the horizontal part is larger than the elbow joint for the cheese joint, so the size that does not pass the horizontal part differs depending on the type of joint. Instead of preparing various sheet-like materials, it is sufficient that the diameter of the hole or the width of the notch is smaller than the length of the horizontal portion 4a of the elbow joint.

  As shown in FIGS. 9 (e) and 9 (g), the sheet-like object as a joint drop prevention tool has slits 72a, 72b, 72c between the holes 70d, 70e, 70f and any one of the sides. It is preferable that it is formed. This is because if there is a slit, it is easy to insert the joint into the hole. Further, if there is a slit, the vertical portion of the joint can be inserted into the hole even after the joint and the external pipe are connected.

  The shape of the hole formed in the sheet-like material may be a perfect circle, an ellipse, or a polygon. Further, for example, as shown in FIG. 9A, only one hole 70a may be formed near the center of the sheet 7a, but the first joint 40a and the second joint 40b may come into contact with each other. There is. Further, as shown in FIG. 9 (h), only one notch 71g may be formed from one side of the sheet-like object 7h. In this case, there is a merit that the joint is easily placed on the notch 71g of the sheet-like object 7h, but there is a possibility that the first joint 40a and the second joint 40b come into contact with each other. Therefore, as shown in FIGS. 9 (b), (c), (d), (e), (f), and (g), the hole or the notch is in contact with the first joint and the second joint. It is preferable that it is formed at a position where it is not. Moreover, when using the sheet-like thing 7h shown in FIG.9 (h), if a curing tape etc. are affixed between the 1st coupling 40a and the 2nd coupling 40b, the contact of both joints can be avoided.

  As shown in FIGS. 9B, 9C, and 9F, notches can be formed on any two sides of the sheet-like material. From the viewpoint of preventing contact with each other, as shown in FIG. 9 (b), it is preferable to form the notches 71a and 71b one by one on two opposite sides.

  The above has described the case where a sheet-like object provided with a hole or notch is used as a fitting fall prevention tool. However, even if such a hole or notch is not provided in the sheet-like object, for example, as shown in FIG. Thus, the hole comprised by a piping hole and a sheet-like object should just be a structure which can prevent a joint from falling. That is, by blocking a part of the piping hole 1a with the sheet-like material 7i, the first joint 70a passes through the vertical portion of the first joint 40a, but does not pass through the horizontal portion of the first joint 40a, and the second joint 40b. A second hole 70h is formed which passes the vertical portion but does not pass the horizontal portion of the second joint 40b. If it does in this way, a joint will not fall from a hole constituted by piping hole 1a and sheet-like object 7i.

  According to the present invention, a relatively large piping hole is provided in the base material, and during construction in the construction method in which two internal pipes and two external pipes are connected by two joints through the piping holes, The joint can be prevented from falling into the pipe hole. Moreover, the load between the connection part of this joint and internal piping after construction by this construction method can be reduced.
