Description

  The present invention relates to a protective cover for a piping material for a panel heater that covers and protects a hot water pipe that is drawn out indoors from a building surface such as a floor surface or a wall surface of a building and connected to a panel heater in the room.

  Conventionally, a panel heater is known as a heating device using hot water as a heat source. As described in JP-A-8-152151, etc., this panel heater has a passage through which hot water passes, and the heat of the hot water passing through this passage is transmitted to a radiation panel provided with fins. Released to the outside. The panel heater is installed on the floor or the like near the indoor wall, hot water pipes that pass through the floor and walls and drawn into the room are connected to the bottom, etc., and hot water supplied from a heat source is supplied from one hot water pipe to the panel. After being supplied to the heater and circulating through the passage in the panel heater, it is returned to the other hot water pipe.

JP-A-8-152151

  However, conventionally, the hot water pipe drawn from the floor or wall surface is piped in an exposed state in the room until it is connected to the bottom surface of the panel heater or the like. Was invited.

  Further, the panel heater is usually installed at a place where it is easy to receive sunlight, such as near a window in a room. On the other hand, resin pipes are frequently used as hot water pipes in recent years. Under such circumstances, as described above, the water pipe is in an exposed state, and is placed in an environment that is easily deteriorated due to the influence of ultraviolet rays of sunlight.

  For this reason, in view of the above problems, it is conceivable to protect the hot water pipe by covering it with a protective cover. However, in that case, the installation position of the panel heater from the floor surface or wall surface is generally not constant, and the distance from the floor surface or wall surface to the panel heater varies, so the protective cover is composed of the panel heater and the hot water pipe. It is necessary to adjust the length according to the interval between the joint connecting the two and the construction surface.

  Therefore, the present invention can improve the appearance of the hot water pipe drawn from the construction surface to the room, can prevent the hot water pipe from being deteriorated by ultraviolet rays, and further, installs a panel heater. An object of the present invention is to provide a protective cover for a piping material for a panel heater that can be easily attached in accordance with the position.

  The protective cover for the piping material for a panel heater according to claim 1 protects the hot water pipe drawn from the construction surface of the building and connected to the panel heater, and covers the hot water pipe drawn from the construction surface. And an adjustment cover that is installed on the construction surface and has an insertion port into which the adjustment cover is inserted. And the said adjustment cover is comprised with a division body, has a joint fitting part which carries out an external fitting to the joint which connects the said panel heater and the said hot water pipe in one side edge part, and the other side is the said construction surface It is formed so as to be cuttable so as to be adjusted to a length corresponding to the distance from the joint.

  The protective cover is usually attached to the hot water pipe from the outside after the piping work for connecting the hot water pipe drawn from the construction surface to the bottom of the panel heater or the like is completed. Since the adjustment cover is constituted by a divided body, the divided body can be attached by attaching the divided body from both sides of the hot water pipe even after the piping work of the hot water pipe is completed.

  Moreover, since the adjustment cover is externally fitted to a joint connecting the panel heater and the hot water pipe, it can be stably attached to the joint without being displaced. The adjustment cover can adjust the length from the tip on the construction surface side to the joint by cutting the other side in parallel with the construction surface using a tool such as a cutter or a saw.

  The protective cover for the piping material for panel heater according to claim 2 has a joint with a valve for connecting the panel heater and the hot water pipe, and further includes a joint cover for covering the joint. The joint cover includes a fitting portion that is fitted to a panel heater side connection portion of the joint with valve, and a connection port to which the adjustment cover is connected.

  That is, this protective cover is composed of three members including a joint cover that covers the joint with valve in addition to the adjustment cover and the installation cover. The adjustment cover is externally fitted to a hot water pipe side connecting portion that connects the panel heater and the hot water pipe of the joint with valve.

  The protective cover for the piping material for the panel heater according to claim 3 is formed so that the adjustment cover can accommodate two hot water pipes, that is, the hot water pipes for going and returning.

  The protective cover for the piping material for panel heater according to claim 4 has a cutting line that can be cut in stages on the other side of the adjustment cover. That is, the cutting line is formed in parallel with a plurality of strips at intervals, and by cutting an arbitrary cutting line, the cutting line from the tip on the construction surface side of the adjustment cover corresponding to the distance between the construction surface and the joint The length to the joint can be adjusted. The cutting line can be formed by a narrow groove or the like.

In the invention of claim 1, since the protective cover covers the hot water pipe drawn out from the construction surface, the appearance of the piping portion of the hot water pipe in the room can be improved.
Further, by covering the hot water pipe with the protective cover, it is possible to block the ultraviolet rays and prevent the hot water pipe from deteriorating.

  In addition, the installation position of the panel heater is not fixed, and the distance from the construction surface to the joint is not constant. Just cut the other side of the adjustment cover in the direction parallel to the construction surface, and the distance between the construction surface and the joint will be reduced. It can be easily accommodated and can cover and protect the entire hot water pipe.

  And since the adjustment cover is inserted into the insertion port of the installation cover, the cut end cut off the other side of the adjustment cover is not smooth but has a serrated shape or is slightly inclined with respect to the construction surface Since the cut end is covered and concealed by the installation cover, the appearance of the cut portion is not deteriorated.

  In the invention of claim 2, the joint with valve is separately covered with a joint cover, and the adjustment cover and the installation cover can be used in common with the joint that connects the panel heater and the hot water pipe having no valve. In other words, the adjustment cover and the installation cover can be used with a joint with or without a valve, so the number of parts can be reduced and the overall cost can be reduced.

  In the invention of claim 3, since the adjustment cover can accommodate two hot water pipes, compared to the case where each hot water pipe is protected by a protective cover, the piping locations of the two hot water pipes are A more coherent and clean appearance can be achieved. Moreover, since two hot water pipes can be accommodated by one protective cover, it is economical.

  In the invention of claim 4, a cutting line that can be cut in stages is formed on the other side of the adjustment cover. By cutting along the cutting line, the adjustment cover is placed at a distance between the construction surface and the joint. It can be easily adjusted to the corresponding length.

In addition, on the inner wall surface 14 of the second adjustment cover half body 13, there are three vertical positions corresponding to the guide holes 22 of the first adjustment cover half body 12 in the guide holes 22 of the first adjustment cover half body 12. A guide protrusion 24 having a cross-shaped cross section to be inserted is provided. The guide protrusion 24 is fitted into the guide hole 22 of the first adjustment cover half 12 and functions as a positioning guide when the two halves are assembled, similar to the protrusion 23, and the guide hole 22. The joint strength between the two halves is increased. The guide holes 22 of the first adjustment cover half body 12 and the guide protrusions 24 of the second adjustment cover half body 13 are provided at three positions in the vertical direction in the center of the inner wall surface 14. It is not limited to the number of installations, and may be set as appropriate, such as four places on the left and right end portions of the inner wall surface 14.

  The outer wall surface 15 visually recognized from the outside of the first adjustment cover half body 12 and the second adjustment cover half body 13 has a design in which a plurality of vertical grooves 15a are engraved at equal intervals. Yes. In addition, you may form the outer wall surface 15 in the smooth surface where these designs are not given.

  Next, as shown in FIGS. 1, 4, and 5, the installation cover 31 has a shape in which an insertion port 35 having a substantially oval shape is formed at the center of a substantially rectangular plate 34. The first installation cover half body 32 and the second installation cover half body 33 are divided into two parts. The first installation cover half-divided body 32 and the second installation cover half-divided body 33 are formed symmetrically except for a part thereof. The installation cover 31 is installed on the floor surface 53, and the other side of the adjustment cover 11 is inserted into the insertion port 35 in a fitted state. The installation cover 31 is formed of a synthetic resin such as an AES resin having weather resistance against sunlight ultraviolet rays.

  Each of the halves of the installation cover 31 is provided with a flange 36 that reaches the entire outer peripheral edge of the substantially rectangular plate 34 and bends toward the floor surface 53, and the front end surface of the flange 36 is grounded to the floor surface 53. . An insertion wall 37 is erected along the peripheral edge of the insertion port 35 provided in the plate 34. The height of the insertion wall 37 is formed longer than the interval between the cutting grooves 20 of the adjustment cover 11. Thereby, even if the adjustment cover 11 is cut at the interval of the cutting groove 20, the cut portion of the adjustment cover 11 is always covered by the insertion wall 37.

  In addition, as shown in FIG. 4, the second installation cover half body 33 is opposed to the both ends of the flange 36 of the first installation cover half body 32. It is projecting toward. A screw insertion hole 38a is formed at the center of the screw mounting plate 38, and an accommodation concave surface 38b for accommodating a screw head is formed at the upper part of the insertion hole. Furthermore, an engaging recess 39 is provided at a position adjacent to the screw mounting plate 38 to engage with an engaging claw 40a of an engaging protrusion 40 of a second installation cover half 33 to be described later.

  On the other hand, as shown in FIG. 5, the engagement projecting piece 40 protrudes from the split surface of the plate 34 of the second installation cover half body 33 toward the first installation cover half body 32, An engaging claw 40 a is formed at the tip of the engaging protrusion 40. The engagement claw 40 a of the engagement protrusion 40 engages with the engagement recess 39 of the first installation cover half 32 to connect the first installation cover half 32 and the second installation cover half 33. Then, the installation cover 31 is set in the assembled state.

  Next, as shown in FIG. 8, the panel heater 52 is installed on the floor surface 53 at a predetermined distance along the indoor wall surface 54. As shown in FIG. 6A, two hot water pipes 51 that are piped through the floor surface 53 are connected to one end of the bottom surface 52 a of the panel heater 52 via a joint 61. Yes. A synthetic resin pipe is used for the hot water pipe 51. A nut 62 is used for the joint 61. A knob 69 of a valve 68 for adjusting the temperature of the hot water is attached to the upper part of the side surface on one side of the panel heater 52.

(Installation procedure)
Next, a procedure for attaching the protective cover 1A of the present embodiment configured as described above to the hot water pipe 51 and the joint 61 between the panel heater 52 and the floor surface 53 will be described with reference to FIGS. First, as shown in FIG. 6A, a case where the distance L1 between the panel heater 52 and the floor surface 53 is large and the distance between the floor surface 53 and the joint 61 is large will be described. 6 (c1), 6 (d), and 6 (e), the vertical groove 15a in the design of the outer wall surface 15 of the adjustment cover 11 is omitted.

  Before attaching the protective cover 1A, the hot water pipe 51 and the joint 61 are exposed between the panel heater 52 and the floor surface 53 as shown in FIG. 6 (a). To attach the protective cover 1A in this state, first, as shown in FIG. 6 (b), the first adjustment cover half-divided body 12 is applied to the joint 61 from the back. At this time, the first adjustment cover half body 12 causes the fitting plate 17 at the upper end portion to abut on the upper surface of the nut 62 of the joint 61 and the two nuts 62 are fitted into the cutout holes 18 of the fitting plate 17. The hot water pipe 51 is inserted into the notch hole 19a of the partition plate 19. In this state, the first adjustment cover half 12 is in a state in which the nut 62 of the joint 61 is fitted to the joint fitting portion 16, so that it is prevented from moving in the vertical and horizontal directions and is held at a fixed position. .

  Subsequently, as shown in FIG. 6 (c1), the second adjustment cover half-split from the front side in FIG. 6 (c1) opposite to the first adjustment cover half-split body 12 with the joint 61 and the hot water pipe 51 interposed therebetween. Attach 13 and attach. At this time, it attaches so that the guide protrusion 24 of the 2nd adjustment cover half body 13 may be inserted in the guide hole 22 of the 1st adjustment cover half body 12. Moreover, it attaches so that the protrusion 23 of the side part of the 2nd adjustment cover half body 13 may engage with the step part 21 of the side part of the 1st adjustment cover half body 12. As a result, the second adjustment cover half-split body 13 is smoothly assembled to the first adjustment cover half-split body 12 by being guided to the assembly position to the first adjustment cover half-split body 12. Further, both the halves are firmly connected by press-fitting the guide protrusions 24 into the guide holes 22. Further, the first adjustment cover half body 12 and the second adjustment cover half body 13 are engaged by the engagement between the step portion 21 of the first adjustment cover half body 12 and the protrusion 23 of the second adjustment cover half body 13. And a gap is prevented from occurring in the split surface. Thereby, an ultraviolet-ray does not enter inside from the split surface of both halves, and can prevent the deterioration of the hot water pipe 51 by an ultraviolet-ray more reliably.

  After the assembly, the adjustment cover 11 is prevented from being deformed and held in a fixed shape by the engagement between the guide protrusion 24 and the guide hole 22 and the engagement between the protrusion 23 and the step portion 21. Further, the hot water pipe 51 and the joint 61 exposed between the panel heater 52 and the floor surface 53 are entirely covered with the adjustment cover 11.

  Next, when the adjustment cover 11 is attached, the first installation cover half-divided body 32 is applied from the back to the lower part of the first adjustment cover half-divided body 12 from the lower side and arranged as shown in FIG. 6 (d). . Then, the screw 55 is inserted into the insertion hole 38 a of the screw attachment plate 38 of the first installation cover half 32 and screwed to the floor surface 53. At this time, the adjustment cover 11 is temporarily held at a fixed position by fitting the joint fitting portion 16 to the joint 61, so that it also serves as a positioning member when fixing the installation cover 31 to the floor surface 53. Therefore, the first installation cover half-divided body 32 may be positioned by being applied to the adjustment cover 11 and fixed to the floor surface 53 by screwing at that position. In addition, since the accommodation concave surface 38b is formed in the screw mounting plate 38 of the first installation cover half-divided body 32, after the head of the screw 55 is accommodated in the inside, the head projects upward and the next It is avoided that the second installation cover half 33 is assembled with the plate 34. By attaching the screw 55, the first installation cover half-divided body 32 is fixed at a predetermined position on the floor surface 53, and at the same time, the adjustment cover 11 is stably held at a fixed position.

  Here, as shown in FIG. 6 (c1), the first installation cover half 32 is attached after the second adjustment cover half 13 is attached and the adjustment cover 11 is assembled. After (b), the process proceeds to FIG. 6 (c2). First, the first installation cover half-divided body 32 is assigned to the lower part of the first adjustment cover half-divided body 12 from the outside, and installed on the floor 53. Therefore, the second adjustment cover half body 13 can be attached to the first adjustment cover half body 12 from the front side.

  When the second adjustment cover half-split body 13 and the first installation cover half-split body 32 are attached as shown in FIG. 6 (d) by any one of the procedures described above, as shown in FIG. 6 (e), 2 Move the installation cover half 33 from the front side of FIG. 6 (e) in a substantially horizontal direction and place it under the second adjustment cover half 13 toward the first installation cover half 32. Push in and assemble. As a result, the engaging claw 40a of the engaging protrusion 40 of the second installation cover half 33 is engaged with the engagement recess 39 provided on the lower surface of the plate 34 of the first installation cover half 32, and the installation cover The assembly of 31 is completed. The state after the attachment is such that the other side of the adjustment cover 11, that is, the lower side is inserted into the insertion port 35 of the installation cover 31. By this insertion, the adjustment cover 11 is prevented from being detached from the installation cover 31 with the lower end portion surrounded by the insertion wall 37 of the installation cover 31. Further, since the screw 55 is covered on the front side by the plate 34 of the second installation cover half 33, the head of the screw 55 is not exposed on the surface side of the installation cover 31, and the head of the screw 55 is exposed. This does not impair the appearance.

  Thus, the attachment of the protective cover 1A to the hot water pipe 51 and the joint 61 is completed. FIG. 7 shows a state in which the protective cover 1 </ b> A after installation covers and protects the hot water pipe 51 and the joint 61. FIG. 8 shows the panel heater 52 and the protective cover 1A after being attached.

Next, as shown in FIG. 9, a procedure for attaching the protective cover 1 </ b> A when the space L2 between the panel heater 52 and the floor surface 53 is small and the space between the floor surface 53 and the joint 61 is small will be described.
In this case, since the total length of the adjustment cover 11 in the vertical direction is larger than the interval L2, it is necessary to cut the other side of the adjustment cover 11 in advance to shorten the total length. When cutting the other side of the adjustment cover 11, the upper end of the adjustment cover 11 where the fitting plate 17 is formed is above the bottom surface 52 a of the panel heater 52 in a state where the adjustment cover 11 is placed on the floor surface 53 as it is. Therefore, the cutting position cannot be determined. In this case, the cutting position can of course be determined if a scale is used, but the cutting position can be determined without using the scale, that is, the cutting groove 20 can be selected, as described below.

  That is, as shown in FIG. 10A, the adjustment cover 11 is turned upside down and placed on the floor 53 in an inverted state. That is, after the adjustment cover 11 is turned upside down, one side of the adjustment cover 11 is placed on the floor surface 53 and the other side is positioned upward. In this state, the upper end where the fitting plate 17 of the adjustment cover 11 is formed, which is in contact with the floor surface 53, is the base end, so that the height with the bottom surface 52a of the panel heater 52 is adjusted to the bottom surface 52a. If a suitable cutting groove 20 is selected, the height to the cutting groove 20 becomes substantially equal to the distance L2 between the panel heater 52 and the floor surface 53. Therefore, the cutting groove 20 may be selected and cut using a tool such as a cutter or a saw. At this time, since the cutting portion is formed by the cutting groove 20, the tool can be moved straight along the cutting groove 20 without detaching from the cutting groove 20. FIG. 10B shows the adjustment cover 11 after cutting.

  In this case, since the cutting grooves 20 are provided at a predetermined interval, the height from the mounting portion on the bottom surface 52a to the cutting groove 20 in the adjustment cover 11 is set to the bottom surface 52a of the panel heater 52 from the floor surface 53. The position of the bottom surface 52a of the panel heater 52 is usually located between the adjacent cutting grooves 20. Therefore, when the bottom surface 52a of the panel heater 52 is at a height located between the adjacent cutting grooves 20, the cutting that is close to the height of the bottom surface 52a of the panel heater 52 and the total length of the adjustment cover 11 is shortened. The groove 20 is selected and cut. This is because, when the cutting groove 20 at a position higher than the bottom surface 52 a of the panel heater 52 is selected and cut from the two adjacent cutting grooves 20, the total length of the adjustment cover 11 is the distance between the panel heater 52 and the floor surface 53. It is because it becomes larger than L2 and the adjustment cover 11 cannot be inserted in the meantime. On the other hand, when the cutting groove 20 at a position lower than the bottom surface 52a of the panel heater 52 is selected and cut from the two adjacent cutting grooves 20, the lower end of the adjustment cover 11 has a short overall length after attachment. The insertion wall 37 is erected on the peripheral edge of the insertion port 35 of the installation cover 31, although it slightly lifts and separates upward from the floor surface 53, so that the lower end of the adjustment cover 11 is covered thereby, and the installation cover This is because it does not leave the insertion opening 35 in the horizontal direction, and the problem that the raised portion is exposed and the appearance is deteriorated does not occur.

  After the entire length of the adjustment cover 11 is shortened corresponding to the distance L2 between the panel heater 52 and the floor surface 53 in this way, the adjustment cover 11 is cut as shown in FIG. The adjustment cover 11 and the installation cover 31 may be attached between the panel heater 52 and the floor surface 53 and the hot water pipe 51 and the joint 61 may be covered by the procedure shown. The state after attaching the protective cover 1A is shown in FIG. In addition, in FIG. 9, in order to show the inside of the protective cover 1A, description of each front half halved body is abbreviate | omitted.

(Function)
Next, the operation of the protective cover 1A of the first embodiment will be described.
Since the protective cover 1A covers the hot water pipe 51 drawn from the floor surface 53, the appearance of the piping portion of the hot water pipe 51 in the room is improved.
Further, by covering the hot water pipe 51 with the protective cover 1A having weather resistance, the ultraviolet rays are blocked and the hot water pipe 51 is prevented from being deteriorated.

  Furthermore, since the vertical length of the adjustment cover 11 can be adjusted simply by selecting from the plurality of cutting grooves 20 on the other side of the adjustment cover 11 and cutting along the cutting grooves 20, the floor 53 and It is easy to attach the protective cover 1A corresponding to the distance from the panel heater 52.

  Since the adjustment cover 11 is inserted into the insertion port 35 of the installation cover 31, the cut surface of the other side of the adjustment cover 11 is not smooth but is formed in unevenness such as a sawtooth shape or parallel to the floor surface 53. Even if it is cut slightly inclined, the cut end is covered with the insertion wall 37 of the installation cover 31 and is not visually recognized from the outside, so that the appearance at the cut portion does not deteriorate.

  Further, if the adjustment cover 11 is reversely inserted into the insertion wall 37 of the insertion port 35 of the installation cover 31, the installation cover 31 is arranged and the half is assembled when the protective cover 1A is assembled. When the adjustment cover 11 is assembled after the installation, the installation cover 31 arranged first has not yet been fixed to the floor surface 53 because the adjustment cover 11 that is also positioned is not yet attached to the joint 61. . Therefore, it is necessary to fix the installation cover 31 to the floor surface 53 by attaching screws to the plate 34 or the like of the installation cover 31 after the installation cover 31 and the adjustment cover 11 are assembled. As a result, the screws are attached from the outside of the plate 34 and the like to fix the installation cover 31, and the head of the screws is exposed on the surface side of the plate 34, so that the appearance of this portion is degraded.

  However, since the adjustment cover 11 of this embodiment is inserted into the insertion port 35 of the installation cover 31, as described above, the first installation cover half-divided body 32 is attached after the adjustment cover 11 is assembled first.
