本考案は添付図面の構成に限定されるものではない。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe cover joint used for connecting a plurality of connected pipe covers such as an air conditioning pipe and a hot water supply pipe. 2. Description of the Related Art In a conventional pipe cover joint, a connecting portion for fitting a connected pipe cover to be connected has a fixed inner diameter corresponding to the outer diameter of the connected pipe cover. (For example, see Japanese Utility Model Application Laid-Open No. 54-110824). [0003] Therefore, every time the diameter of the connected pipe cover to be connected is different, it is necessary to replace the joint body in accordance therewith. If the connection pipe covers have different diameters from each other, it is necessary to prepare different diameters of the connection parts of the joint body for each connection part, and it is necessary to prepare a large number of various kinds of joint bodies. The disadvantage in terms of product cost was unavoidable. To solve such inconvenience, for example, prepare a large joint body,
It is conceivable to fill the gap between the connection part of the joint body and the pipe cover with the filler after the completion of the pipe construction and the construction of the pipe cover and the joint, but in this case, the work of filling the filler is troublesome. , Work can only be done after the completion of the installation of pipes and pipe covers, and there are many losses in the work process,
There is also a problem that it is difficult to perform maintenance and inspection of the piping. Still another solving means is a cylindrical connecting portion formed at both ends with a small-diameter end for internally fitting the connected pipe cover and a large-diameter end for internally fitting to the joint main body separately from the joint main body. However, in this case, since the connecting portion is a tubular unit, it is necessary to pass the pipe from the free end side of the pipe in advance before connecting the pipe to the device, and the installation procedure There is a problem that assembling of the pipe cover itself becomes impossible if the mistake is made. Moreover, if an adhesive or a screw is used to fix the joint body and the connection cylinder member, the connection between the joint body and the connection portion requires a great deal of trouble. The present invention uses a small number of types of joint bodies to connect a larger number of different types of connected pipe covers with different diameters, as well as the work of installing pipes and pipe cover joints, and the work of connecting the joint bodies and connecting parts. It is another object of the present invention to provide a pipe cover joint which can be easily performed. [0004] The technical means of the present invention for achieving the above object is to provide a pipe cover joint for connecting a plurality of connected pipe covers, the pipe cover joint being connected to a pipe cover joint. A plurality of connection portions for fitting the connection pipe cover,
The connecting portion is formed from a joint body formed of a separate member, and the connecting portion has a small-diameter end portion on one end side into which the connected piping cover is fitted, and the joint main body on the other end side. It is composed of a connecting cylinder member having a large-diameter end portion fitted therein, and each of the joint body and the connection cylinder member,
The split main body is configured so that it can be divided into two in the radial direction. Further, of the pair of divided main bodies constituting the joint main body, one of the divided main bodies installed on the side where the cover is to be attached is provided with an engagement protrusion on the pipe housing space side. And a fixing screw insertion hole for the cover mounting target portion is provided, and one of the pair of split cylindrical members constituting the connection cylindrical member, one of the split cylinders installed on the cover mounting target portion side. The member is provided with an engaged through-hole in which the engaging protrusion is freely engageable, and the connected pipe is provided on an inner peripheral portion of the one of the divided cylindrical members closer to the small-diameter end than the engaged through-hole. That is, a step for positioning the tip of the cover is provided. [0005] A stopper may be provided at the inner peripheral portion of the divided main body between the engaging projection and the fixing screw insertion hole, for positioning a tip of the connected pipe cover. The operation of the above technical means is as follows. a. Because the connecting part was configured with a separate member from the joint body,
By simply preparing various diameter pipes for each connection part, the connected pipe covers of various diameters can be easily connected. b. Since each connection part was also divided into two parts in the radial direction together with the joint body, one of the joint body and one of the connection cylinder members forming the connection part were previously installed at a predetermined location, and then, on their inner surfaces. The pipe is constructed along the pipe, and then the other joint body and the connecting tubular member can be mounted from above. Therefore, there is no need to pass the joint body and each connection portion from the free end side of the pipe in advance before connecting the pipe to the device, and there is no need to worry about the installation procedure with the pipe cover or the pipe cover joint. Easy to install. c. One of the joint body and one of the connection tubular members are
Since the engagement protrusion is connected to the engaged through hole through which the engagement protrusion is freely engageable, the one joint body and the one connection cylinder member that are divided into two are engaged with the engagement protrusion. Connection and disconnection can be performed easily and in a short time by engaging and disengaging with the joint through-hole. Further, the engagement protrusion is provided so as to protrude toward the pipe housing space side with respect to one of the divided main bodies installed on the side where the cover is to be mounted, of the pair of divided main bodies, and Since the through-hole is provided for one of the pair of divided tubular members that is provided on the side of the cover mounting target, the engaging protrusion protruding toward the pipe housing space (front side). As a mark, one of the divided cylinder members can be engaged so that the engaged through hole is engaged, and one of the divided main body and one of the divided cylinder members can be easily engaged. Can be. Then, just by looking at the state of the engaging projections protruding to the front side through the engaged through holes, it is possible to confirm the state of engagement of the two at a glance and to achieve reliable engagement. d. Since one of the divided main bodies constituting the joint main body is provided with a fixing screw insertion hole for a cover mounting target location, one of the divided main bodies can be easily mounted to the cover mounting target location and one of the split cylinders With the member engaged with one of the split main bodies, it is mounted to the cover mounting target location, and then piping work is performed, and simply by attaching the other split main body and connecting tube member, the piping work is speedily performed. It becomes possible. Furthermore, if one of the divided bodies is attached to the cover mounting target in advance, it can be used as an indicator of the mounting position of the pipe and the connected pipe cover or the pipe cover joint, or can be used for the pipe and the connected pipe cover or the pipe cover joint. It can also be used to temporarily support them during mounting. e. An inner peripheral portion of the one of the divided tubular members closer to the small-diameter end than the engaged through-hole is provided with a step portion for positioning the distal end of the connected pipe cover. By pressing the tip of the connected pipe cover, positioning in the approach direction can be achieved.
Therefore, the connected pipe cover enters the connection cylinder member too much, and the engagement protrusion is damaged, or the connected pipe cover is located on the fixing screw insertion hole of the joint body, and the fixing screw tightening operation is not performed. It can be prevented from becoming an obstacle. Therefore, even after setting the connecting cylinder member and the connected pipe cover to the holding portion, it is possible to smoothly perform the re-tightening operation of the fixing screw inserted through the fixing screw insertion hole,
For example, the joint body is temporarily attached with a fixing screw to a cover mounting target in advance, and the connecting cylinder member and each pipe cover are arranged in a predetermined position along with the fixing body, and then the fixing screw is fully tightened to fix the mounting state. It is possible to easily carry out a pipe cover attaching method such as fixing. F. Also, at the inner peripheral portion of the one divided body,
If a stopper for positioning the leading end of the connected pipe cover is provided, for example, when the connected pipe cover is directly fitted to the holding portion in an inner fitting state, the end of the connected pipe cover is connected to the stopper. By doing so, the relative positioning between the joint body and the connected pipe cover can be performed,
The fitting margin of the connected pipe cover becomes a predetermined value, so that the connected pipe cover can be stably held. Further, since the stopper is provided on the inner peripheral portion of the one divided main body between the engagement projection and the fixing screw insertion hole, the connected pipe cover is set in the holding portion when the connected pipe cover is set on the holding portion. The cover is positioned by the stopper, and it is possible to prevent the end of the connected pipe cover from covering the fixing screw insertion hole beyond the position of the stopper. Therefore,
Smoothly retighten the fixing screw inserted into the fixing screw insertion hole even after the connected pipe cover is set on the holding part, because it is unlikely to hinder the operation of attaching and detaching the fixing screw in the fixing screw insertion hole. For example, the joint main body is temporarily attached with a fixing screw in advance to a cover mounting target portion, and after each piping cover is arranged at a predetermined position, the fixing screw is fully tightened to determine the mounting state. This makes it possible to easily carry out a pipe cover mounting method such as [Effects of the Invention] The above a. The pipe cover joint is substantially divided in the pipe length direction due to the action of, and the pipe cover joint that can easily connect many types of connected pipe covers is replaced by replacing only the divided connection parts. , At low cost. B. B. The effect of (1) is to effectively utilize the fact that the pipe cover joint is divided even in the radial direction, and there is an effect that the installation of the cover can be easily completed after the completion of the piping work. C. The above c. , One of the two joint bodies and one of the connecting cylinder members can be easily connected and disconnected by the engagement and disengagement of the engagement projection and the engaged through-hole, and the conventional adhesive or screw is used. There is less troublesome construction than in the case where it is necessary, so, for example, even when piping on a wall or ceiling surface that is difficult to maintain a predetermined posture for a long time, one side of the joint body fixed to the wall surface or ceiling surface The connection tube member can be held by a simple engagement operation, and there is no need to fix the connection tube member to a wall surface or a ceiling surface separately from the main body, so that there is an effect that construction efficiency can be improved. D. The above d, e, f. , The pipe cover can be securely attached, and the flexibility in the process for temporary fixing and permanent fixing of the joint body is increased, and work rework is reduced and overall work efficiency is improved. It becomes possible. E. The above a, b, c, d, e, f. Due to the effect of (1), not only the work of installing the pipe cover joint at the cover mounting target portion, but also the whole pipe work can be performed smoothly, efficiently and reliably in a short time. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 8, one outdoor unit 1 installed outdoors and two first units installed separately indoors 2A and 2B are provided.
The second indoor units 3A and 3B are connected to each other by two reciprocating air conditioning pipes A and B. In order to cover the air-conditioning pipes A and B, two air-conditioning pipes A and B connected to the first indoor unit 3A are inserted and held inside, and are directly mounted on a vertical wall surface W which is an example of a cover mounting target location. The second air-conditioning pipes A and B connected to the tubular first connected pipe cover 4A and the second indoor unit 3B are inserted and held inside, and the second air-conditioning pipes A and B are attached to the vertical wall surface W.
