Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fluid pipe protection device that is used in a protective cover that is attached to a wall surface of a building and that can hold two types of fluid pipes having different diameters using the same protective cover.
[0002]
[Prior art]
For example, in a water pipe made of a hard vinyl chloride pipe, a plurality of types having different “nominal diameters” are defined according to JIS regulations. As shown in FIG. 6, the water pipe is used in a state in which a protective cover C in which a base and a lid are assembled is attached to a wall surface of a building and is housed and protected in the protective cover C. For this reason, the manufacturer of the protective cover has produced only a plurality of types of dimensions corresponding to the “nominal diameter” defined in JIS. On the other hand, it is necessary for the contractor to have various types of protective covers having the same size as the number of water pipes having different “nominal diameters”. Furthermore, it is necessary to carry a large amount of various types of protective covers having different sizes to the construction site during construction, and there is a problem that the construction site becomes very complicated.
[0003]
Moreover, it was necessary to use protective covers one by one according to the size of the water pipes to be piped, and it was very troublesome. For this reason, even if the diameter of the pipe to be piped is changed during piping, the protective cover that is not dimensionally compatible before the change is used as it is without changing to a protective cover of the size corresponding to the pipe after the change. And sometimes piped. Conversely, if the size of the protective cover is changed at the branch of the water pipe, etc., the aesthetics will be lost, so even if the diameter of the pipe is changed, the size of the protective cover will not change and In some cases, the corresponding protective cover was used as it was.
[0004]
In actual construction, water pipes outside the JIS standard that do not fall under the “nominal diameter” are frequently used, and since there is no appropriate protective cover corresponding to this, it is more than the water pipes outside the standard used. Because it was necessary to select and install an existing protective cover with a large size, it was required to sell an appropriate protective cover for non-standard water pipes.
[0005]
Furthermore, when a protective cover that does not correspond to the diameter of the water pipe is used, a predetermined gap is generated between the protective cover and the water pipe accommodated therein. Due to the presence of this gap, the water pipe oscillates in the protective cover and collides with the inner peripheral surface of the protective cover due to a light water hammer phenomenon that occurs when water starts and stops. There was also a problem of making a sound.
[0006]
[Problems to be solved by the invention]
In view of the above circumstances, an object of the present invention is to enable two types of fluid pipes having different diameters to be held using the same protective cover.
[0007]
[Means for Solving the Problems]
The invention of claim 1 for solving this problem includes a long protective cover that houses and protects the fluid pipe by assembling the base and the lid, a holding portion that holds the fluid pipe, A fluid pipe holder having an opening for inserting the fluid pipe into the holding part, and a holding part for holding the large-diameter fluid pipe is formed inward on the base of the protective cover. Further, the holding portion is formed to be opposed to each other in a bent state, and the fluid pipe holder can be expanded outward by elastic deformation so as to fit and hold the fluid pipe holder therein. The claw portions are formed outwardly at both ends of the opening, the fluid pipe holder is positioned so that the opening faces the tube insertion side, and the claw portion covers the protective cover. Arranged between the holding parts of the base by engaging the opening side end of the holding part of the base Is attached, by the holding portion of fluid pipe inserted small diameter from the opening, it is characterized by retaining in the protective cover.
[0008]
According to the first aspect of the present invention, when a non-standard fluid pipe is used, even if an existing protective cover corresponding to the standard fluid pipe is used, the base of the protective cover is bent inward. Since the fluid pipe holder can be positioned and arranged between the holding parts formed opposite to each other so that the opening always faces the pipe insertion side, the base attached to the wall surface of the building etc. On the other hand, when the fluid pipe is inserted from the pipe insertion side, the fluid pipe is accommodated in the base while being held by the fluid pipe holder attached to the base. After that, if the lid is covered with the base on which the fluid pipe is held and accommodated through the fluid pipe holder by a normal construction, the non-standard (small diameter) fluid pipe becomes the standard (large diameter). It is housed and protected in an existing protective cover corresponding to the fluid pipe. As a result, according to the first aspect of the invention, the same protective cover can be used to hold two types of fluid pipes, that is, a standard (large diameter) fluid pipe and a nonstandard (small diameter) fluid pipe. In addition, they have different diameters and can hold two types of standard fluid pipes.
[0009]
In this way, the non-standard fluid pipe is housed and protected in the existing protective cover corresponding to the standard fluid pipe, so that it is not necessary to prepare for production of a protective cover corresponding to the non-standard fluid pipe. Further, the fluid pipe is firmly fixed inside the protective cover that is not dimensionally compatible. Furthermore, the fluid pipe holder is placed and attached in advance between the holding parts of the protective cover base, and the rest is housed and protected in the same manner as in normal construction. In addition, since the fluid pipe holder is attached to the base of the protective cover, it is not necessary to adjust the position of the holder after piping.
[0010]
Also, when the fluid tube holder is pushed in from the opening of the base of the protective cover, the claw portions at both ends on the opening side of the fluid tube holder engage with the end of the opening side of the holding portion of the base, and the base A fluid tube holder is non-rotatably attached. In this state, the small-diameter fluid pipe is pushed into the inside through the opening of the fluid pipe holder so as to be reliably accommodated. The holding portion of the base of the protective cover is bent inward to fit and hold the fluid pipe holder inside, and can be expanded outward by elastic deformation. The fluid pipe holder is partially fitted and held inside the holding part of the protective cover, and claw parts formed outwardly at both ends of the opening of the fluid pipe holder are formed on the base of the protective cover. It is a structure engaged with the opening side end of the holding part. Therefore, the fluid pipe holder is securely engaged with both ends of the opening of the holding part of the protective cover in a state where the fluid pipe holder is fitted and held inside the holding part of the base of the protective cover. When the small-diameter fluid pipe is pushed from the opening of the fluid pipe holder, the small-diameter fluid pipe can be reliably pushed into the fluid pipe holder and securely held without turning the fluid pipe holder.
[0011]
[0012]
[0013]
The invention of claim 2 is characterized in that, in the invention of claim 1, the fluid tube holder is arranged over the entire length of the protective cover, so that the small diameter fluid tube extends over the entire length. The small diameter fluid pipe can be more firmly fixed inside the protective cover by being held by the fluid pipe holder.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to embodiments. 1 is a cross-sectional view of a state in which a water pipe P is housed and protected using a fluid pipe holder S _{1 according} to the present invention, FIG. 2 is a perspective view of the same, and FIG. 3 is a fluid pipe protection device. It is an exploded perspective view of each member which constitutes. 1 to 3, the fluid pipe protection device includes an existing protective cover C corresponding to a standard water pipe, and a fluid pipe holder S ₁ attached to a base 10 constituting the protective cover C. The The protective cover C is a long resin molded product, and includes a base 10 in which the water pipe P is accommodated, and a lid 20 that covers the entire base 10, and has a length of an attachment portion. Used by cutting.
[0015]
The base 10 constituting the protective cover C includes a stepped bottom plate portion 11 having a central portion in the width direction higher than both end portions, and a pair of side plate portions 12 provided integrally on the upper surface of the bottom plate portion 11. The side plate portion 12 is provided at the step portion of the bottom plate portion 11, and the side plate main body portion 12 b is provided at the upper end portion of the side plate base portion 12 a provided perpendicular to the bottom plate portion 11. Yes. The lower end portion of the side plate main body portion 12b is bent toward the outside, and the upper end portion is bent toward the inside. Since the side plate portion 12 has the above shape, a fitting convex portion 23 of the lid 20 described later is fitted between the lower end portion thereof and both end portions in the width direction of the bottom plate portion 11. The fitting recess 13 is formed along the longitudinal direction.
[0016]
On the other hand, the lid body 20 has a shape in which side plate portions 22 are integrally provided on both sides of the top plate portion 21, and the lower portion is open. The fitting convex part 23 of the hollow structure fitted to the ten fitting recessed parts 13 is provided facing each other along the longitudinal direction.
[0017]
As shown in FIG. 6, the protective cover C is constructed by fixing the base 10 to the wall surface W of the building, inserting a standard water pipe through the opening on the front face, The lid 20 is fixed to the base 10 by covering the lid 20 with the fitting 10 and fitting the fitting convex portion 23 of the lid 20 with the fitting recess 13 of the base 10. The internal water pipe is protected. When a standard water pipe is accommodated in the base 10 of the protective cover C, the water pipe is accommodated in an immobile state in which both side plate portions 12 of the base 10 are slightly expanded outwardly. No gap is formed between the inner peripheral surface of the table 10 and the water pipe.
[0018]
The fluid pipe protection device according to the present invention uses the protective cover C described above to make the non-standard water pipe P smaller in diameter than the standard water pipe non-oscillatable and accommodate it in the base 10. It is about to try. The fluid pipe holder S ₁ used to achieve this is obtained by removing a part of the cylindrical body having the same outer diameter as that of the standard water pipe corresponding to the protective cover C in the circumferential direction. It is the structure which made the part the opening part 1. FIG. That is, as shown in FIG. 1 and FIG. 2, the fluid pipe holder S ₁ is provided with an opening 1 in a part of the holding part 2 in the circumferential direction, and claw parts 3 at both ends of the opening 1. Are bent outwardly, and each claw portion 3 is a side plate body portion on both side plate portions 12 of the base 10 in a state where the entire fluid pipe holder S ₁ is accommodated in the base 10. Engage with the upper end of 12b. The diameter (inner diameter) of the fluid pipe holder S ₁ corresponds to the outer diameter of the non-standard water pipe P accommodated in the existing protective cover C.
[0019]
In order to use the fluid pipe protection device having the above-described configuration to make a non-standard water pipe P having a smaller diameter than the standard water pipe corresponding to the protective cover C constituting the non-vibrating pipe, the following is possible. To do. First, as shown in FIG. 6, after fixing the base 10 to the piping position of the wall surface W of the building with screws or the like, the fluid pipe holder S ₁ is inserted from the opening of the base 10 facing the front. When pushed in, both side plate portions 12 of the base 10 are expanded outward by elastic deformation, and the entire fluid pipe holder S ₁ is accommodated in the base 10. The respective claw portions 3 are respectively engaged with the distal end portions of the side plate portions 12 of the base 10, and the fluid pipe holder S ₁ is attached to the base 10 so as not to rotate. Thus, since the fluid pipe holder S ₁ is attached to the base 10 fixed to the wall surface W, the opening 1 always faces the front surface.
[0020]
In this state, when a non-standard water pipe P is pushed into the base 10 in the same manner as normal piping, both side plates 12 of the base 10 and the holding part 2 of the fluid pipe holder S ₁ Are integrally elastically deformed outwardly, and the non-standard water pipe P is inserted into the inside through the opening ₁ of the fluid pipe holder S ₁ and partially fitted and held in the holding part 2. It is accommodated in the base 10 in a state. After the water pipe P is accommodated in the base 10, the both side plate portions 12 of the base 10 that have been elastically deformed outward and the holding portion 2 of the fluid pipe holder S ₁ are close to the original shape. Will be restored. Thereafter, when the lid 20 is covered with the base 10 fixed to the wall surface W in the same manner as in normal construction, the construction is completed.
[0021]
Thus, water pipes P nonstandard housed protected inside (in base 10) of the protective cover C is because it is held in a plurality of fluid conduits retainer S ₁ at a predetermined interval, the base Even if there is a gap between 10 and the water pipe P, the water pipe P is held so as not to swing with respect to the base 10. Of course, the protective cover C is accommodated and protected by a standard water pipe corresponding to the protective cover C. Therefore, the same protective cover C is used for the standard water pipe and the non-standard water pipe. Two types of water pipes with different diameters can be accommodated and protected.
[0022]
FIG. 4 shows another embodiment of the present invention. The fluid pipe holder S ₂ of the present embodiment has a pair of fitting legs 4 fitted between a pair of side plate bases 12 a constituting each side plate 12 of the base 10 on the outer peripheral surface on the bottom side. It is the structure which the opening part 1 was provided and the lacking part of the circumferential direction of the holding part 2 became. When the pair of fitting legs 4 provided on the fluid pipe holder S ₂ is fitted between the pair of side plate bases 12a of the base 10, the opening 1 is always forward (pipe). It will face the insertion side).
[0023]
In the above embodiment, the fluid pipe holders S ₁ and S ₂ are attached at predetermined intervals along the longitudinal direction of the base 10 constituting the protective cover C, and are accommodated in the base 10. The water pipe P has a structure that is partially supported by a plurality of fluid pipe holders S ₁ (S ₂ ). However, as shown in FIG. 5, the cross-sectional shape is the same as that of the fluid pipe holder S ₁ , but a fluid pipe holder S ₃ having a very long length is prepared, and the base 10 By attaching the fluid pipe holder S ₃ over the entire length, the water pipe P accommodated in the base 10 may be held with the fluid pipe holder S ₃ over the entire length. As a result, the water pipe P can be more firmly fixed in the protective cover C that is not dimensionally compatible.
[0024]
Further, each of the fluid pipe holders S ₁ and S ₂ described above is not only attached to the straight protective cover C but also an attached cover C ′ such as an elbow or a joint for connecting the straight protective cover C. It can also be attached to the base (see FIG. 6). Thereby, the center of the water pipes mutually connected corresponds.
[0025]
Moreover, although the said embodiment is an example which accommodates and protects two types of water pipes, a standard water pipe and a non-standard water pipe, with respect to the same protective cover, the diameter is different according to the present invention. Of course, it is possible to accommodate and protect two types of water pipes in the same protective cover.
[0026]
【The invention's effect】
Since this invention is the said structure, the following various effects are show | played. (1) Since the diameters are different and both of the two types of standard fluid pipes can be accommodated and protected in the same protective cover, the manufacturer manufactures or holds the contractor in this respect. The number of types of protective covers to be reduced is reduced, and management of protective covers including proper use at construction sites becomes easier. (2) As a result of non-standard fluid pipes being housed and protected in existing protective covers corresponding to standard fluid pipes, the same protective cover can be used to create non-standard fluid pipes and non-standard fluid pipes. The two types of fluid pipes can be accommodated and held. For this reason, it is not necessary to prepare for manufacturing a protective cover corresponding to a non-standard fluid pipe. (3) Even when the diameter of the fluid pipe to be piped is changed in the middle of piping, the protective pipe which is not dimensionally compatible before the change can be used as it is, and the changed fluid pipe can be piped without any trouble. (4) By simply placing the fluid pipe holder between the holders formed on the base of the existing protective cover corresponding to the standard fluid pipe, the fluid pipe is placed inside the protective cover that is not dimensionally compatible. We can fix well. (5) The fluid pipe holder is provided with a portion for positioning the opening so that the opening always faces the pipe insertion side when the holder is attached to the base of the protective cover. After the fluid pipe holder is attached to the base, the opening does not shift in the circumferential direction. Just like in the conventional method, the fluid pipe is simply inserted through the base opening. A fluid pipe can be accommodated in the base. (6) Even when a non-corresponding fluid pipe is accommodated inside the protective cover, the fluid pipe can be held so as not to swing.
