Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a duct for storing air conditioning piping for an air conditioner or the like.

[Conventional technology and its problems]

Such air conditioning piping is installed between a heat source device placed outdoors and an indoor unit, and consists of a combination of outgoing and returning piping to circulate hot water or refrigerant, and is installed along the outer wall of a building. There are many things.

Even though the outer periphery is covered with a heat insulating material or the like, mounting it exposed is unsightly and undesirable from the viewpoint of maintaining durability.

Therefore, it is possible to store these pipes and drain hoses together in a duct.One example of this is to store a cylindrical body 1 with a substantially rectangular or circular cross section, as shown in Utility Model Publication No. 58-49013. is formed by a combination of divided bodies 2 and 3 that fit into each other at edges 2a and 3a, and pipes 5 and 6 are installed inside the divided bodies 2 and 3.
and a drain pipe 7. (See Figure 6).

Hard vinyl chloride resin or the like is suitable for the structural members of the cylinder 1 as it has excellent weather resistance and impact resistance. After fitting 5, 6, and 7, the other divided body 2 is fitted into the divided body 3. At this time, an elastic band plate 8 is interposed so that the tubes 5, 6, and 7 are fixed inside the cylinder body 1 to prevent them from floating up. Edge 3a
its ends are fixed. Therefore, the elastic band plate 8
If a force is applied to the end edge 3a, the elasticity of the divided body 3 itself will be lost, and there is a possibility that the engagement with the divided body 2 will not be successful.

In order to eliminate these conventional drawbacks,
As shown in FIG. 7, it is also conceivable to attach the bundle 9 by using screw holes provided in advance in the divided body 3 or by drilling holes as appropriate. However, in such a method, when screw holes are used, the bundle 9 can only be attached to the part with the hole, and if the attachment is forgotten, it is difficult to attach it after piping. On the other hand, even with the hole-drilling method, it is necessary to pass the bundle 9 through the hole before attaching the divided body 3 to the wall, and similar troublesome work is required.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide an air conditioning piping duct in which workability is improved because a required number of piping holding members can be easily attached to arbitrary locations without impairing the fitting action between the divided bodies.

[Means for solving problems]

In order to achieve the above-mentioned object, in the case where a cylindrical body is formed by divided bodies that fit into each other at the end edges, the present invention has been developed on both sides of a protrusion provided in the longitudinal direction on the inside of one of these divided bodies for fixation. A locking edge protruding to the side is provided, and both ends of the locking edge having a substantially U-shaped cross section are provided with inward protruding edges that engage with the locking edge, and the bundle extends to both sides. The gist is to fit the pipe holding member.

[Effect]

According to the present invention, the pipe holding member is attached to the locking edges formed to protrude laterally on both sides of a specially provided protrusion, so the location can be freely selected, and the split body It can be set even after it is attached to a wall or the like. Furthermore, since the pipe holding member is not coupled to the divided bodies other than at the locking edge, it does not adversely affect the fitting of the divided bodies to each other.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a longitudinal side view showing one embodiment of the duct of the present invention, and Fig. 2 is a perspective view of one of the divided bodies. Reference numbers are attached.

That is, in the figure, 1 is a cylinder that becomes a duct, 2, 3
indicates a divided body formed by fitting the cylinder 1, and these divided bodies 2 and 3 may be made of light metal such as extruded aluminum, or synthetic resin such as vinyl chloride or polyethylene, as long as they are somewhat deformable. No questions asked.

Among these, 3 in the figure is a divided body that is attached to the wall surface 10 side, and is a relatively flat and shallow gutter-shaped body, and the end edge 3a has an engaging groove 1 that bulges inward and extends outward.
1 is formed in the length direction, and a tongue piece 12 is further provided which extends by bending the tip into a dogleg shape and slightly tilting inward. In addition, the center of the bottom of the divided body 3 is raised inward in a U-shape to form protrusions 13 in the length direction, screw holes 15 are provided at appropriate intervals here, and the upper surface is horizontally extended to the left and right. The locking edge 14 is integrally formed so as to protrude.

On the other hand, the divided body 2 is a cover body with a relatively deep U-shaped cross section, and the end edge 2a is bent inward to form a locking claw piece 1.
6 is integrally molded continuously in the length direction.

FIG. 3 is a perspective view showing an example of the piping holding member 17, in which a nail metal-like bundle 9 and a substantially C-shaped fitting member 18 are shown.
The fitting member 18 has a size such that the end edge 18a of the opening thereof engages with the lower surface of the locking edge 14.

In addition, as shown in FIG. 4, this pipe holding member 17 has several steps of protrusions 19a on one side and a plurality of engagement holes 19b on the other side instead of the nail-like binding body 9, as shown in FIG. Binding bands 19 arranged in parallel may be used, and if these are made of synthetic resin like the fitting member 18, both can be integrally molded and the assembly work can be simplified.

Next, to explain how to use it, Figure 5 is a perspective view showing how it is used, showing the outdoor unit 2 of the air conditioner.
From 0, piping is provided along the wall surface 10, and in order to cover this with the duct of the present invention, the divided body 3 is first attached to the wall surface 10 with screws 4. Once the divided body 3 is set in advance in this way, fit the necessary number of pipe holding members 17 by inserting their fitting members 18 from the end of the locking edge 14, and then slide them as they are to set the appropriate intervals. Arrange with. In addition, as another method for attaching the pipe holding member 17, it may be fitted from above without sliding, and the pipe holding member 17 may be crimped and fixed by caulking.

In either case, there is a slight gap between the fitting member 18 and the upper surface of the protruding strip 13 on the side of the divided body 3, so that the head of the screw 4 can be positioned here.

Next, the outgoing and incoming pipes 5 and 6 and the drain pipe 7 are placed in the divided body 3 and tied together with a binding body 9. Then, the divided body 2 is fitted into the divided body 3. At that time, if the divided body 2 is strongly pressed, the tongue pieces 12 will approach each other inwardly, and the locking claw pieces 16 of the divided body 2 will be attached to the divided body 3. Side engagement groove 1
It slips smoothly into 1 and does not come out.

[Effect of idea]

As described above, in the case where the air conditioning piping duct of the present invention forms a cylindrical body with divided bodies that fit into each other at the edges, the required number of pipe holding members can be easily installed in the cylindrical body. The installation location can be freely selected. Furthermore, it can be set even after one of the divided bodies has been fixed to a wall surface, etc., which prevents forgetting to attach it.Furthermore, since it is not connected to the divided body except at the locking edge, the fitting effect of the divided bodies to each other is impaired. It also belongs to others.
