Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cover for air conditioning piping, which includes a cover body and a lid member detachably attached to the cover body.

[Conventional technology]

Conventional air conditioning piping covers are shown in Figures 11 and 1.
As shown in Figure 2, a bottom wall for receiving air conditioning pipes 3 and a pair of side walls are integrally molded so as to cover each air conditioning pipe 3 connecting a set of indoor units and outdoor units 1. The cover body 6 has been formed.

[Problem that the invention seeks to solve]

However, as shown in FIG. 11, for example, when a large number of outdoor units 1 are arranged side by side, a cover body 6 and a lid member 7 must be installed for each air conditioning pipe 3 connected to each of the outdoor units 1. Not only does this require a lot of work and construction costs, but it also has the disadvantage of making maintenance such as inspection and repair difficult.

An object of the present invention is to provide an air conditioning piping cover that can accommodate air conditioning piping for a large number of outdoor units or indoor units at once.

[Means for solving problems]

The characteristic structure of the cover for air conditioning piping of the present invention is that a pair of side wall members are provided to form the cover body, and a receiving member for the air conditioning piping extending between the both side wall members is arranged at approximately the same length in the longitudinal direction of the both side wall members. Arranged at intervals, both ends of the receiving members and one end edge in the width direction of each of the side wall members are removably connected to each other via bolts inside each of the side wall members, Both end edges in the width direction of the lid member and the other end edges of each of the both side wall members are removably connected to each other via bolts between the both side wall members, and the longitudinal direction of the bolt is It is located along the width direction of the side wall member, and its effects are as follows.

[Effect]

As shown in FIGS. 1 to 3, the cover 4 is provided with a cover body 6 and a lid member 7 that is detachably attached to the cover body 6, and the cover body 6 is provided with a pair of side wall members 8, 8.
and a receiving member 9, and a large number of air conditioning pipes 3 connected to a plurality of outdoor units 1 (or indoor units) are housed in one cover 4 at a time, reducing construction work.
By simply removing the lid member 7 from the cover body 6, it is possible to inspect and repair a large number of air conditioning pipes 3 at once. The air conditioning piping 3 can be easily taken out from any position along the length of the cover 4 by passing the air conditioning piping 3 between the adjacent receiving members 9 and 9 without complicated bending of the piping 3. However, in particular, both ends of the receiving member 9 and one end edge in the width direction of each of the side wall members 8, 8 are removably connected to each other via bolts 10 inside each of the side wall members 8, and the bolts 10 By arranging the longitudinal direction of the side wall member 8 along the width direction of the side wall member 8, the outer part of the side wall member 8 can be attached and detached in a state where it extends outward from the receiving member 9, and the predetermined width of the receiving member 9 The width of the internal space of the cover 4 can be made larger than that of the cover 4, and the other end edges of the side wall members 8, 8, which are both end edges in the width direction of the lid member 7, are
They are each detachably connected via bolts 10 between them, and the longitudinal direction of the bolts 10 is aligned with the width direction of the side wall member 8, so that the side wall member 8 can be placed close to the building wall 10. By opening and closing the lid member 7, multiple piping can be installed along the building wall W.

〔Effect of the invention〕

Therefore, construction costs and maintenance costs can be kept low, while the width of the internal space of the cover can be increased relative to the predetermined width of the receiving member, and a large number of pipes can be installed with the side wall member placed close to the building wall. Since the cover can be installed at the same time, the capacity for accommodating air-conditioning piping can be particularly improved, and the piping construction is less likely to be subject to space constraints.

〔Example〕

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

As shown in Figs. 1 to 3, a pair of reciprocating air conditioning pipes are connected separately between a plurality of outdoor units 1 installed in parallel outdoors and a plurality of indoor units 2 installed indoors. An air conditioning piping cover 4 is attached to a ceiling wall surface A and an outdoor floor surface B via fixtures 5, with a plurality of pairs of air conditioning piping being inserted and held in the interior side by side to form an air conditioning piping facility.

As shown in FIGS. 4 to 7, the cover 4
is a cover body 6 of a fixed length made of sheet metal and painted.
and a cover member 7 detachably attached thereto, forming the cover main body 6, a pair of side wall members 8, 8 are provided, and a receiving member 9 for air conditioning piping is provided between the both side wall members 8, 8. Both ends of the receiving member 9 and the edge portions 8A, 8A in the width direction of the both side wall members 8, 8 are arranged at approximately equal intervals in the longitudinal direction of the side wall members 8, 8.
They are each detachably connected via bolts 10 on the inside of each, the longitudinal direction of the bolts 10 is aligned with the width direction of the side wall member 8, and between adjacent receiving members 9, 9,
A bottom plate member 11 is arranged and detachably attached to the end edges 8A, 8A of both side wall members 8, 8 with bolts 10.

The side wall member 8 has a reinforced cross-sectional shape with both end edges bent, and the inner surface of the other end edge 8B opposite to the one end edge 8A connected to the receiving member 9. Nut 12 is welded to the
The lid member 7 is arranged on the cover body 6, and the lid member 7 can be fixed to the cover body 6 simply by screwing a bolt 10 from above between the side wall members 8, 8.

The receiving member 9 is made into a reinforced shape by bending a single plate, and has a connecting bolt insertion hole 13 for the mounting tool 5 in the intermediate portion in the longitudinal direction.

Each of the bolts 10 is mounted using a countersunk bolt so that the head does not protrude outward.

As shown in FIGS. 4 and 8, the connection structure between the covers 4 and 4 is such that longitudinally adjacent side wall members 8 and 8 are connected by a pair of inner and outer joint members 14A and 14B for the cover main body 6, respectively. At the same time, the adjacent lid members 7, 7 are clamped and connected by a pair of inner and outer joint members 15A, 15b for the lid member 7, and the outer joint member 14A for the cover main body 6 and the side wall member 8 , and lid member 7
As shown in FIG. 8, seal members 16 are interposed between the joint member 15A and the cover member 7 to prevent rainwater from entering the cover 4.

Furthermore, as shown in FIG. 6, a ring-shaped seal packing 1 is provided between the cover member 7 and the bolt 10 that fixes it to the cover body 6 to prevent rainwater from entering.
7 is sandwiched between them.

In the figure, reference numeral 18 denotes a corner cover for changing the piping direction of a plurality of air conditioning pipes 3. Like the cover 4, it is composed of a lid member 7 and a cover body 6, and the corner part Reinforcing plates 20 for connection are attached across both side wall members 8, 8.

A fixture 5 for attaching the cover 4 to the outdoor floor surface B has a vertically expandable structure and is configured to be height adjustable.

[Another example]

When the cover 4 is placed indoors, the bottom plate member 11 needs to be installed across both side wall members 8, 8 for fire protection and to prevent condensation from dripping on the surface of the air conditioning piping 3. It is not always necessary if the

The shape of the receiving member 9 may be modified in various ways.

If the number of air conditioning pipes 3 is large, cover 4
may be stacked in two or more layers, as shown in FIG.
B are connected to each other with bolts, and a special joint member 19 for the cover body is used at the longitudinal connection between the covers 4 and 4 to prevent rainwater from entering the cover 4. .
