Abstract

PURPOSE:To ensure sufficient thermal insulation effect, while blocking longitudinal shift of thermally insulated piping positively, by a constitution wherein pressing parts are provided at two or more points movably toward the central part of the thermally insulated piping from different directions. CONSTITUTION:First engaging parts 8a, 8a are engaged with one engaging groove 2b and second engaging parts 8b, 8b are pressed into the other engaging groove 2c. A thermally insulated piping P is then mounted at a pipe supporting part on the upper face of a supporting beam 2 and an operating bolt 9 is rotated until guide protrusions 7b, 7b reach predetermined values on a scale 10. Consequently, cam parts 7a, 7a come into contact each other to move first and second pressing parts 6c, 6c and 7c toward the central part O of the thermally insulated pipe P from different directions thus fixing the pipe P in place.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fixture for insulated piping, which is provided with a pressing portion for fixing the insulated piping placed on the piping support by pressing it. .

[Conventional technology]

Conventionally, in the above-mentioned fixtures for insulated piping, as shown in, for example, Japanese Utility Model Application No. 64-41785,
As shown in the figure (one pipe support (21) and one pressing body (22) have an arc-shaped pipe support part (21a) on the opposing surface.
) and a pressing part (22a) are formed separately so as to be movable in directions facing each other, and the heat insulating piping (P) is sandwiched between the piping support part (21a) and the pressing part (22a). It was fixed.

[Problem to be solved by the invention]

However, in the above-mentioned conventional configuration, one pressing part (22a) is attached to one pipe support part (21a) facing each other.
) of the heat insulating pipe (P), the heat insulating material (A) of the heat insulating pipe (P).

There was a problem in that (A) was deformed into a flattened shape, resulting in a thin portion, which significantly reduced its heat insulating effect.

Further, the position holding force in the longitudinal direction of the heat insulating pipe (P) fixed to the pipe fixture is increased by the force of holding the position in the longitudinal direction of the pipe supporting part (21a) and the pressing part (22) as the heat insulating material (A) deforms.
The pressing of the insulated pipe (P) against a) is due to frictional force caused by force, or the sum of the frictional forces caused by the flat deformation of the insulating materials (A) and (A) is small; There was also the problem that the piping (P) was easily displaced in its longitudinal direction.

An object of the present invention is to provide a fixture for insulating piping that can strongly prevent displacement of fixed insulating piping in the longitudinal direction while sufficiently maintaining the heat insulating effect of the heat insulating material.

[Means to solve the problem]

In order to achieve the above object, the first characteristic configuration of the insulated piping fixture according to the present invention is that a pressing part is provided for fixing the insulated piping placed on the piping support part by pressing it. The configuration is such that the pressing portions are provided at two or more locations, and each of the pressing portions is configured to be movable from different directions toward substantially the center of the heat insulating piping, and each of the pressing portions is provided at two or more locations in the heat insulating piping. The reason is that an operating member is provided that is operated to move toward approximately the center of the screen.

Preferably, a second characteristic configuration of the present invention is such that, in the first characteristic configuration, one end of the pressing portion is supported by the piping support portion and the other end is configured to be swingable. The reason is that it is formed into two pressing members.

[For production]

According to the first characteristic configuration of the present invention, the pressing portion is
In addition, each of these pressing parts is configured to be movable from different directions toward the approximate center of the heat insulating piping, so that each of the pressing parts can be moved toward the approximate center of the heat insulating piping by operating the operating unit. When moved towards
The piping support portion and the two pressing portions press the insulation piping toward the approximate center from at least three different directions. Therefore, the heat insulating material of the heat insulating pipe is pressed and deformed substantially uniformly from the periphery thereof, thereby preventing the formation of extremely thin parts, thereby suppressing a decrease in the heat insulating effect. In addition, since it is possible to prevent the formation of extremely thin parts in the insulation material, the total amount of deformation of the insulation material and the total frictional force between the insulation piping and the piping support part and the pressing part due to the deformation are reduced. Growing up,
The heat insulating piping can be strongly fixed in a state where it is difficult to shift in the longitudinal direction.

On the other hand, according to the second characteristic configuration of the present invention, the two pressing members forming the pressing part swing the other end with one end on the side of the piping support part as a fulcrum, and Since it is held and fixed in the space surrounded by the pressing part and the pipe support part, the fixation is reliable.

〔Effect of the invention〕

As described above, according to the present invention, there is provided a fixture for insulated piping that can strongly prevent displacement of the fixed insulated piping in the longitudinal direction, and can sufficiently maintain the insulation effect of the heat insulating material in the fixed part. We have reached the point where we can provide
It is now possible to reduce energy loss in insulated piping systems, such as those found in air conditioning systems.
