Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a cylindrical air-conditioning piping cover consisting of a pair of half-covers that can be freely engaged and connected to each other. The present invention relates to a structure in which insertion portions for screw members for fixing the cover to a wall surface are formed at appropriate intervals in the longitudinal direction of the cover, and in which air conditioning piping is disposed in a space within the cover for air conditioning piping.

[Conventional technology]

By configuring the air conditioning piping cover as a combination of a pair of half-split covers as described above, compared to the case where the air conditioning piping cover is configured with a simple cylindrical cover, it is possible to connect the piping from the end of the cylinder into the cylinder. This eliminates the troublesome construction work of inserting the pipe through the air conditioning piping, and can greatly improve the workability of air conditioning piping. However, when using such a half-split cover, one half of the It is necessary to push the piping along one split cover into the space inside the half cover while fixing the other half cover, and this work is relatively troublesome.

Therefore, in the past, as shown in Japanese Utility Model Publication No. 58-49013, for example, an elastic band plate for preventing lifting of the piping is used, and the pipe is inserted from one half cover fixed to the wall side. The pipe was held down so that it did not protrude, and the other half cover was attached in that state.

Although this can be expected to significantly improve overall workability, if air conditioning piping is installed along a long vertical wall, the piping inside the cover may be damaged due to equipment vibration or long-term use. There was a risk that the pipes would shift and loosen at the bottom, causing problems such as poor flow of drain water and the heavy weight of the pipes acting on connections with equipment.

To avoid the above inconvenience, for example, as shown in Utility Model Publication No. 59-10462, the air conditioning piping is fixed directly to the mold surface, and the outside of the piping is shaped like a U-shape. It is not impossible to consider constructing it so that it is covered with a cover, but if this is done, the cylindrical cover itself made of a pair of half-split covers, which can effectively avoid the effects of wind and rain etc. The advantages are lost, and new problems arise, such as rainwater intrusion that adversely affects connected equipment.

[Problem that the invention attempts to solve]

This invention takes advantage of the characteristics of an air conditioning piping cover constructed using a pair of half-split covers.
Its purpose is to solve the various problems mentioned above when installing long pipes in vertical walls.

[Means for solving problems]

The technical means of the present invention taken to achieve the above object is to attach a wall surface to one half cover of a cylindrical air conditioning piping cover consisting of a pair of half covers that can be freely engaged and connected to each other. In a structure in which insertion portions for cover fixing screw members are formed at appropriate intervals in the longitudinal direction of the cover, and the air conditioning piping is disposed in the space inside the air conditioning piping cover, the air conditioning piping is tightened. A fixing band is attached to the saddle, and the saddle is fixed in the cover via the screw member or bolt/nut inserted through the insertion part, and by taking this technical means, The following actions and effects can be obtained.

[Operation] In other words, the air conditioning piping inside the cover is tightened and fixed by the band attached to the saddle, so if the saddles are installed at appropriate intervals in the longitudinal direction of the cover, the air conditioning piping inside the cover will be fixed in the axial direction. It will not shift, sag, or move during construction, and will be fixed to the cover.

In addition, since the saddle is integrally fixed to the cover using a screw member or bolt/nut using the insertion part, the saddle is inside the cylindrical space of the air conditioning piping cover, which is composed of a pair of half covers. , can be provided within the cover, and therefore,
Because this saddle is provided, there is no need to make the cylindrical space inside the cover an open space where rainwater and the like can easily enter.

Furthermore, the structure on the cover side for fixing the saddle for providing a band for tightening air conditioning piping inside the cover is pre-installed in order to screw this type of cover close to the wall surface. Since the insertion portion is used, there is no need to provide a separate saddle fixing structure or the like.

[Effect of idea]

(b) Due to the above-mentioned effects, the construction work of accommodating the air conditioning piping inside the cover can be carried out efficiently, and the displacement movement of the air conditioning piping inside the cover can be well prevented, thereby avoiding the negative effects caused by loosening of the pipes. .

(b) Due to the above-mentioned effects, it is possible to effectively avoid the adverse effects on the equipment due to the intrusion of rainwater, etc. from the outside.

(c) Due to the above-mentioned effect, the saddle can be fixed to the cover with a simple structure without requiring any special modifications to fix the saddle to the cover.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 4, in air conditioners such as coolers and boilers, the air conditioner is exposed along the outside of the wall W between the outdoor unit 5 installed outdoors and the indoor unit 6 installed indoors. Two reciprocating air conditioning pipes A and B are fixed to the wall W while being inserted into a pipe cover C to form an air conditioning piping facility.

The piping cover C is constructed as shown in FIGS. 1 and 2. In other words, a rectangular tube-shaped cover body 1 made of a hard resin with excellent weather resistance and impact resistance such as hard vinyl chloride resin is divided into two parts in the circumferential direction, and one half of the cover body 1A or 1B is divided into two halves in the circumferential direction.
Two corner parts 1a spanning a range of approximately 45 degrees at the central angle of
are curved into an arc shape, and the two half-tubular members 1A and 1B have openings facing each other at both side edges along the openings thereof. 1A and 1B are moved relatively close to each other from the sides of the air conditioning pipes A and B, and the opposing walls on both sides of the opening on the side of one half-tubular member 1A are elastically displaced inward to be relatively separated. Elastic engagement recesses 1Aa, 1Aa, 1Ba, and 1Ba, which can be elastically engaged and connected and separated by movement, are integrally formed, and the bottom wall of one half-cylindrical member 1A has a local part. An inward protrusion 1Ab is integrally formed along the longitudinal direction of the cover, and screw members 2 for fixing the cover to the wall surface W are attached to the protrusion 1Ab at appropriate intervals in the longitudinal direction. The insertion portions 3 are arranged in parallel.

As shown in FIGS. 1 to 3, a saddle 7 having a substantially gate-shaped longitudinal section is provided in the cover C and is fitted onto the protrusion 1Ab from above. A resin band 8 for tightening and fixing A and B is attached, a hole 9 is formed through which the screw member 2 is inserted, and the screw member 2 is inserted into the hole 9 and the insertion portion 3 at the same time to the wall W By fixing, the cover C and the saddle 7 are fastened together and fixed.

With the saddle 7 fixed to the cover C, the band 8 attachment part 10 of the saddle 7 is attached to the cover C.
The mounting portion 10 is formed to bulge inward.
, two insertion holes 11 are formed on both left and right sides for inserting and attaching the band 8 along the circumferential direction of the cover C, and an opening 12 is formed on one side in the longitudinal direction of the cover C. Thin wall part 1 on the other side
3 is formed, and a new opening 1 can be created by breaking the wall part 13 as necessary.
3' is formed, and the band 8 is inserted through the opening 13' and the opening 12, so that the direction in which the band 8 is attached to the saddle 7 can be changed.

Note that the saddle 7 and band 8 are each molded from synthetic resin.

D in the figure is a drain hose whose one end is connected to the indoor unit 6.

[Another example]

The saddle 7 may be made of metal instead of synthetic resin.

The saddle 7 does not need to be fastened together with the cover C at all the insertion parts 3 provided on the protrusion 1Ab, and the parts where the plurality of insertion parts 3 are fastened together may be selected depending on the site situation.

The cover C may not form the protrusion portion 1Ab.

The saddle 7 may have a flat shape that simply rests on the protrusion 1Ab, instead of a gate shape that fits onto the protrusion 1Ab.

As shown in FIG. 5, when the cover C is mounted apart from the wall surface W using the mounting fittings 15, the saddle 7 is attached to the cover C using bolts and nuts inserted through the insertion portion 3. 16 may be used for connection and fixation.

The insertion portion 3 may be a hole penetrating the front and back sides, or may be a portion that can be opened more easily by on-site formation than other portions, as shown in FIG. .
