Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe protection device and a pipe protection structure for protecting air-conditioning pipes arranged on a roof of a building from wind and rain, direct sunlight, salt damage and the like.

[0002]

2. Description of the Related Art A number of air conditioning pipes for connecting an outdoor unit and an indoor unit of an air conditioning facility are installed on the roof of a building. Conventionally, in order to protect such air-conditioning pipes arranged outdoors from wind and rain, direct sunlight, salt damage, etc., it has been practiced to collectively cover a plurality of pipes with a pipe cover and support them with a mounting base. Japanese Patent Publication No. 4-5877 describes an example of a pipe cover used for such a purpose and a pipe protection structure using the pipe cover.

FIG. 13 is an exploded perspective view of the pipe cover described in the above publication, and FIG. 14 is a sectional view of a main part of a pipe protection structure using the pipe cover. As shown in FIG. 13, this piping cover 1 is divided into a cover body 2 and a lid 3. The cover body 2 includes a pair of side walls 4 and 4 facing each other with a space therebetween.
And a plurality of pipe receiving members 5 hung between the lower portions of the side walls 4 and 4, and the lid 3 is hung between the upper portions of the side walls 4 and 4 of the cover body 2 by bolts. It is designed to be combined. When using this piping cover 1 to protect piping, first, as shown in FIG. 14, a mounting base 6 is erected on a floor surface 7 such as a rooftop, and the cover main body 2 is placed on the mounting base 6. Then, fix with bolts 8. Next, the pipe 9 is installed on the pipe receiving member 5 located at the inner bottom portion of the cover body 2, the lid 3 is closed after the installation of the pipe 9 is completed, and the lid 3 is bolted to the upper ends of the side walls 4 and 4 of the cover body 2. Connect at 10. Thereby, the illustrated pipe protection structure is obtained.

[0004]

In the above-described conventional example, the load of the pipe 9 is received by the pipe receiving member 5 connected to the side walls 4 and 4 of the pipe cover 1. Therefore, the load of the pipe 9 is not a little applied to the side walls 4 and 4. At the place where the mounting base 6 is arranged below the pipe receiving member 5, the load of the pipe 9 almost directly acts on the mounting base 6. Therefore, if the number of mounting bases 6 is increased, the load applied to the side walls 4 and 4 can be reduced. However, the number of mounting bases 6 cannot be increased so much due to cost and construction reasons. Therefore, it is necessary to place the side walls 4 and 4 with a certain degree of strength for receiving the load of the pipe 9. That is, the side walls 4 and 4 of the conventional pipe cover 1 play a role as a strength member that bears the load of the pipe 9, and it is necessary to increase the wall thickness in order to have a corresponding strength. Moreover, depending on the magnitude of the load of the supporting pipe 9, it is necessary to take measures such as increasing the number of the mounting bases 6.

Further, in the above-mentioned conventional example, since the cover body 2 including the side walls 4, 4 and the pipe receiving member 5 receives the load of the pipe 9, the side walls 4 already standing on both sides when the pipe 9 is installed. Was an obstacle, and it was difficult to install the pipe 9. Furthermore, since the pipe cover 1 is divided into the cover body 2 and the lid 3 and the pipes 9 are connected to each other by bolts after the pipes 9 are installed, it is troublesome to carry out the work on site. Therefore, there is also a problem that the workability is not high as a result.

In consideration of the above circumstances, the present invention can minimize the number of mounting bases to be mounted, prevent the piping load from acting on the piping cover, and facilitate the installation work of the piping and the piping cover. It is an object of the present invention to provide a pipe protection device and a pipe protection structure that can be applied to the above and can improve the workability.

[0007]

According to a first aspect of the present invention, there is provided a pipe protection device, a mounting base arranged at intervals in a pipe extending direction, a pair of vertical frames and a horizontal rail as a pipe receiving member. It is a ladder consisting of and a frame that is installed between the mounting bases by fixing the longitudinal ends of the vertical frame to the mounting bases, and is integrally molded in a U-shaped cross-section that has a top wall and both side walls. It is characterized by comprising a pipe cover arranged so as to cover the pipe to be placed.

A pipe protection structure according to a second aspect of the present invention is the pipe protection structure in which the pipe is protected by using the pipe protection device according to the first aspect, and a plurality of the mounting bases are arranged at intervals in the extension direction of the pipe. The frame is installed between these mounting bases, both longitudinal ends of the vertical frame of the frame are fixed to the mounting base, pipes are placed on the horizontal rails of the frame, and the pipe cover covers the pipes. It is characterized in that both ends of the piping cover in the longitudinal direction are fixed to either the mounting base or the frame by covering.

[0009]

In the pipe protecting apparatus of the first aspect of the present invention, since the load of the pipe is completely received by the frame, the pipe load does not act on the pipe cover at all.
Therefore, the pipe can be installed on the frame regardless of the pipe cover.

In the pipe protection structure according to the second aspect of the present invention, since the pipe can be placed on the frame when the mounting base is installed and the frame is fixed to the mounting base, the pipe cover is not obstructed. The piping can be installed on the frame. Further, all the loads of the piping on the frame act on the mounting base via the frame, and no piping load acts on the piping cover. Further, the weight of the piping cover is applied to the mounting base via the frame or directly.

Further, the rubber packing 410 is formed to have a size to be sandwiched between the upper joint plate 404 and the inner side plate 406, and when the bolt 476 is penetrated, the rubber packing 410 is closed so that water does not enter from the gap of the penetrating portion. have.

A joint portion 400B in the middle of the frame 200
Also for (for convenience, this joint part is obtained by the joint device 400B, it is indicated by the same reference numeral as the joint device 400B), as shown in FIG. 8, the pipe cover 300 is connected similarly to the joint part 400A. It is supposed to do.

Next, the assembly procedure will be described. First, the mounting pedestals 100 are arranged at intervals along the direction in which the pipe is to be extended.
Set up. At that time, the verticality of the mounting base 100 is set in advance by using the adjusting bolt 160 of the base plate 154. Then, while properly sliding the upper leg 106 and the lower leg 108, the pedestal 102 of the mounting base 100
And the upper leg 106 is fixed to the lower leg 108. Then, attach the frame 200 to the mounts 100, 10
0, and as shown in FIGS. 4 and 6A, the both ends of the vertical frame 202 of the frame 200 are attached to the mounting base 100,
The frame 100 is placed on the end portion of the receiving plate 120 of 100, and the frame 200 is fixed to the receiving plate 120 with the bolts 250.

Before and after this, the joint device 400A
The joint frame main body 420A forming the joint frame 402A is fixed on the pedestal 102 of the mounting base 100. That is, the side plate 4
The lower end flange 428 of 22 is fixed to the backing plate 120 and the pedestal 102 by the bolt 430. Further, the joint frame main body 420B of the joint device 400B provided in the middle of the frame 200 is fixed to the vertical frame 202 of the frame 200 with bolts 430 as shown in FIG.

Then, as shown in FIG. 1, the frames 200 are continuously arranged in a ladder shape, and the joint frame main body 422A,
The side plates 422, 422b of 422B are in the form of standing on the side of the frame 200. So, in this state, frame 2
Install the pipe on top of 00. Then, it is possible to proceed with the installation work of the pipe without any obstacles (side wall of the pipe cover 300, etc.) on the side. Further, in this case, the side plates 422 and 422b of the joint frame main bodies 420A and 420B stand on the side portions of the frame 200, so that the side plates 422 and 422b prevent the pipes from falling off. Therefore, the work becomes easier. In particular, the side plates 422 and 422b are
Since it is integrated as the U-shaped joint frame main bodies 420A and 420B, the joint frame main bodies 420A and 420B have high strength and are useful for stably preventing the pipes from falling off. After the pipe is installed, the band 50 may be attached to the long hole 442 as necessary as shown in FIG.
, And then bundle the pipes 9.

After the installation of the pipes is completed, the joint frame upper plate 450 is attached to the side plates 42 of the joint frame main bodies 420A and 420B.
It is fixed to the upper ends of 2, 422b with flat head screws 456. Next, the pipe cover 300 is covered so as to cover the pipe and the frame 200, and the ends of the pipe cover 300 are superposed on the outer surfaces of the joint frames 402A and 402B assembled in a square shape. Then, the rubber packing 410 is wound around the outside so as to cover the gap between the ends of the pipe cover 300, and the joining side plate 406 and the joining upper plate 404 are sequentially arranged on the outside, and the joining side plate 406 and the joining side plate 406 and the joining side plate 406 are joined by the bolt 476. The upper plate 404 is joined to the joint frames 402A and 402B, whereby the end of the pipe cover 300 is clamped and fixed, and the connection of the pipe cover 300 is completed.

In the pipe protection structure completed in this way, since the load of the pipe is entirely received by the frame 200, the mounting bases 100 arranged at both ends of the frame 200 are installed.
Thus, the load of the pipe is sufficiently supported. Therefore, the number of mounting bases 100 can be minimized. In addition, the piping cover 300
The load of the pipe will not work at all. Therefore, it is not necessary to increase the strength of the piping cover 300 so much, and the thickness of the piping cover can be reduced and the weight can be reduced.

Further, when the frame 200 is set, the piping can be installed regardless of the piping cover 300, so that the side wall of the piping cover becomes an obstacle and the installation work of the piping becomes difficult. Absent. Further, since the pipe cover 300 is an integrated product, the number of parts is small, unnecessary fastening work is unnecessary, and the pipe cover 300 can be made lightweight, so that the workability is good. Furthermore, the piping cover 30
Since 0 has both ends fixed to the joint frames 400A and 400B on the mounting base 100 or the frame 200, it can be reliably supported with the minimum number of supporting points. Further, since the joint portion 400B at a place other than the mounting base 100 is reliably supported by the frame 200, the pipe cover 3
00 is stable.

The joint device (joint portion) 400B arranged in the middle of the frame 200 is actually used for the rising portion of the pipe as shown in FIG. In this figure,
The piping not shown rises diagonally from the horizontal part and the building K
Being guided inside. Then, the mounting base 100 arranged at the end of the horizontal portion and the connecting metal fitting 600 provided at the inlet of the building K
An oblique frame 200P is erected between and, and pipe covers 300P, 300Q, 300R are sequentially covered on the frame 200P, and the pipe covers 300P, 300Q, 300R are connected by joint devices (joint portions) 400A, 400B.

Further, the pipe cover 30 used in the above embodiment.
In addition to 0, a pipe cover 300G for two-stage stacking as shown in FIG. 10 may be used. This two-tier stacking pipe cover 300G has a height larger than that of the pipe cover 300 shown in FIG.
The rest of the configuration is the same as that of FIG. 3 only with extra steps. FIG. 11 shows a pipe cover 30 for two-stage stacking.
It is a detailed view of joint part 400A when 0G is used. In this case, the height of the side plate 422 of the joint frame 402A is higher, and the intermediate support member 490 is fixed to the middle stage. As shown in FIG. 12, the intermediate support member 490 is obtained by welding the side plates 422 and the flanges 494 that are screw-fixed to both ends of the main body 492 having a hat cross section.
A long hole 442 having the same purpose as that of the connecting member 424 is formed in the main body 492. Joint part 400 in the middle of frame
B may be similarly configured. In the case of stacking in two stages in this way, the joint frames 402A, 402B as the strength members
Serve as a support substrate for the intermediate support material 490.

Incidentally, the mounting base 100 in the above embodiment.
In addition to being installed on the floor, it may be installed on the wall. Further, the frame 200 and the piping cover 300 may be bent in the horizontal direction or may be bent in the vertical direction.

[0041]

As described above, according to the first aspect of the invention, the load of the pipe is entirely received by the frame. Therefore, if the mounting bases are arranged at both ends of the frame, the load of the pipe is sufficiently increased. Can be supported. Therefore, the number of mounting bases can be minimized. In addition, since it is possible to prevent the pipe load from acting on the pipe cover at all, there is no need to increase the strength of the pipe cover, including the side wall, and the wall thickness of the pipe cover can be reduced to reduce the weight. It will be possible. In addition, since the piping can be installed on the frame regardless of the piping cover, the side wall of the piping cover does not obstruct the installation work of the piping and the workability is good. Becomes Further, since the piping cover is an integrated product having both side walls and the ceiling wall, the number of parts can be small, and extra fastening work is unnecessary, so that the workability is improved.

According to the second aspect of the present invention, since the pipe is protected by using the pipe protection device of the first aspect, the same effect as that of the first aspect can be obtained. Further, since both ends of the piping cover are fixed to either the mounting base or the frame, the piping cover can be reliably supported even with the minimum number of supporting points, and the workability of the piping cover is further improved. .
