BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe cover structure in which a joint body is provided with a plurality of connecting portions for internally fitting a pipe cover to be connected.

[0002]

2. Description of the Related Art Conventionally, this type of pipe cover structure has a plurality of connected pipe covers for covering the pipes and a plurality of connecting portions for internally fitting the connected pipe covers to be connected. The inner diameter of the connection pipe cover is determined according to the outer diameter of the connection pipe cover, and the pipe cover joint is integrally formed.

[0003]

Therefore, every time the diameter of the connected pipe cover to be connected differs, it is necessary to replace the pipe cover joint with one having a connection portion having a diameter suitable for the connection. Yes, and if multiple connected pipe covers to be connected to one pipe cover joint have different diameters, it is necessary to prepare different diameters for the joints of the pipe cover joints. In addition, the disadvantage in terms of product cost inevitably that a large number of various pipe cover joints had to be prepared was unavoidable. In order to eliminate such an inconvenience, for example, prepare a larger pipe cover joint, and after filling the pipe and the pipe cover or joint, the gap between the joint of the pipe cover joint and the pipe cover is filled. However, in this case, the work of constructing the filling material is troublesome, and the work can be performed only after the completion of the construction of the pipe and the pipe cover, and there are many losses in the work process. However, there is a problem that it is difficult to perform maintenance and inspection of piping.
As yet another means for solving the problem, a pipe cover joint is formed at both ends of a small diameter end portion for internally fitting the connected pipe cover and a large diameter end portion for internal fitting to the joint body separately from the joint body. It may be considered that the pipe has a cylindrical connecting member, but in this case, since the connecting member is a cylindrical integral body, the pipe is connected from the free end side before connecting to the device. There is a problem that it is necessary to pass it through in advance, and if the construction procedure is incorrect, the assembly of the pipe cover itself cannot be done. Moreover, since an adhesive or a screw is used to fix the joint body and the connecting cylinder member, there is a great deal of troublesome work for connecting the joint body and the connecting portion. The present invention is capable of connecting a plurality of types of pipe cover joints having different diameters to each other by using a few types of pipe cover joints, and performing work for constructing pipes and pipe cover joints, and a joint body that constitutes the pipe cover joint. It is an object of the present invention to provide a pipe cover joint in which connection work between a pipe and a connecting portion can be easily performed.

[0004]

To achieve the above object, a characteristic structure of the present invention is that a small diameter end portion for internally fitting and connecting a connected pipe cover is formed at one end, and a large diameter for internally fitting and connecting to a joint body. A connecting cylinder member having an end formed at the other end is assembled to at least one of the connecting portions, and the joint body and the connecting cylinder member are configured to be bisectable in the radial direction, and divided. In addition to providing an engaging projection on one of the joint bodies, a receiving portion that engages with the engaging projection is provided on one of the divided connecting tubular members, and a longitudinal direction that straddles the engaging projection on the connected pipe cover. It is in the place where the concave groove along is formed.

[0005]

The operation of the above-mentioned characteristic structure is as follows. a. Since the connecting cylinder member that is a member separate from the joint body is provided, it is only necessary to prepare a connecting cylinder member having a small-diameter end portion having a diameter corresponding to each connecting cylinder member, and the dimension setting of the joint body is constant. , It is possible to easily connect the connected pipe covers of various diameters. b. Since the connecting tube member is also divided into two in the radial direction together with the joint body, one of the divided joint body and one of the divided connecting tube members are installed at predetermined locations in advance,
Pipes can be constructed along those inner surfaces, and then the other joint body and the connecting cylinder member can be mounted from the upper side. Therefore, the installation position of one connected pipe cover or pipe cover joint (joint body or connecting cylinder member) whose installation position is determined in advance with respect to the installation location is the installation position of the pipe and the other connected pipe cover or pipe cover joint. It can be used as an index for efficient piping work, and there is no need to worry about the procedure for attaching the pipe cover or the pipe cover joint, and it is easy to install. c. The joint body and the connection cylinder member can be connected by an engagement protrusion formed on the joint body side and a receiving portion formed on the connection cylinder member side so as to be engageable with the engagement protrusion. Since it is configured, it is possible to connect and disconnect the joint body and the connecting cylinder member, which are divided into two, easily and in a short time by engaging and disengaging the engaging projection and the receiving portion. d. Since the recessed groove along the longitudinal direction straddling the engagement protrusion on the joint body side is formed in the connected pipe cover, the connected pipe cover having the outer diameter dimension corresponding to the inner diameter dimension of the connection portion is directly formed. When fitting, it becomes possible to install the connected pipe cover in a state of straddling the engaging projection with the concave groove, and the engaging projection hinders the direct connection between the joint body and the connected pipe cover. Can be done without.

[0006]

[Effect of the invention] a. Above a. From the action of, the pipe cover joint is in a state of being substantially divided in the pipe length direction, and a pipe cover joint that can easily connect many types of connected pipe covers, by replacing only the divided connection part,
It was able to be provided at low cost. B. Above b. From the effect of, by effectively utilizing that the pipe cover joint is also divided in the radial direction, the installation position of one of the connected pipe covers and the pipe cover joint whose installation position is determined in advance with respect to the installation location is used as an index, The piping work itself can be performed efficiently, and unlike the prior art, the work of previously passing the connecting cylinder member from the free end side of the pipe before connecting the pipe to the equipment is unnecessary. After the work is completed, the cover can be easily installed. C. Above c. From the effect of the above, the joint body and the connecting tubular member which are divided into two can be easily connected and disconnected by engaging and disengaging the engaging projection and the receiving portion, and the construction can be performed as compared with the conventional case where an adhesive material or a screw is used. Therefore, even when connecting to a wall surface or ceiling surface where it is difficult to maintain a predetermined posture for a long time, one connecting cylinder member can be easily attached to one joint body fixed to the wall surface or ceiling surface. Since the connecting cylinder member does not need to be fixed to the wall surface or the ceiling surface separately from the main body, the construction efficiency can be improved. D. Above d. From the effect of the above, it is reasonably possible to adopt a use mode in which a connecting tubular member is not used for any of the plurality of connection parts provided in the joint body as one connection mode, and the pipe cover joint and the cover can be connected to the pipe cover joint without increasing the number of parts. There is an advantage that the number of combinations with the connection piping cover can be increased and various combinations can be realized.
