It relates to insulation construction methods used to maintain temperature, such as heat retention or insulation, and particularly relates to insulation construction methods that allow such insulation construction work to be performed easily and at low cost.

[Prior Art] As the heat-insulating covering mat used in the above-described heat-insulating construction method, for example, when performing heat-insulating construction on piping, a sewn mat has conventionally been used.

This sewing mat is made by filling a cylindrical exterior material with an open end at least with a heat insulating mat and sewing the openings together, and the mat is sewn in advance at a factory equipped with sewing machines before being attached to piping components. It is.

However, it is common for valves and other piping components to have different shapes and dimensions for each manufacturer, or even for the same manufacturer depending on the type and type. Since it is not possible to perform sewing at the site, it is necessary to go to the site in advance, measure the dimensions of each piping member, sew a special mat, and then go to the site again to perform the covering work, which takes time and effort in preparation. There have been problems in that it is troublesome and increases the cost.

In addition, it is not easy to undo the sewn seams, and as mentioned above, it cannot be sewn on-site, so even if the insulation mat needs to be replaced, it cannot be easily replaced. There were also problems.

[Problems to be Solved by the Invention] In view of the above-mentioned circumstances, the present invention eliminates the need to visit the work site many times, and allows the user to check the shape of valves, other piping members, or other parts to be insulated at the work site. By making it possible to create the insulation material and the covering material covering this insulation material in the appropriate shape and size, it is possible to perform the covering work with flexibility at the insulation construction work site. In addition, it is an object of the present invention to provide a heat insulation construction method that facilitates the replacement of internal heat insulating materials or other members and can be implemented at low cost.

[Means for Solving the Problem] That is, the first invention according to the present application is a heat insulating material in which a sheet-like heat insulating material having a required size and a covering material capable of covering this heat insulating material are overlapped. constitutes a covering mat,
With a hanging gap formed between the fixture and the covering material, a predetermined number of arbitrary locations of the heat-insulating covering mat are fixed with the fixture, thereby forming a heat-insulating covering mat with a fixture; The heat-insulating covering mat with fixing tools covers the desired heat-insulating construction area, and tightening string material is hooked between the fixing tools to tighten the heat-insulating covering mat into an openable/closable state. This is an insulation construction method.

Further, the second invention constitutes a heat-insulating covering mat in which a sheet-like heat insulating material having a required size and a covering material capable of covering the heat-insulating material are stacked, and the mat for heat-insulating covering A tightening belt and a tightening ring hooked to the tightening belt are provided on the outer surface of the tightening belt, and a gap for hooking is formed between the fixing device and the covering material, and the fixing device is used to tighten the insulation coating. A predetermined number of arbitrary parts of the mat are fixed to form a heat-insulating covering mat with fixed parts,
This heat insulation covering mat with fixing tools covers the desired heat insulation construction area, a tightening string material is hooked between the fixing tools to close the open part, and the tightening belt covers the heat insulation covering mat. This insulation construction method is characterized in that the other open portion is closed, and the tightening ring presses the heat-insulating covering mat from the outside to tighten the heat-insulating covering mat into an openable/closable state.

[Function] In the first invention described above, a heat insulating covering mat having a structure in which a heat insulating material of an arbitrary size and shape is covered with a covering material is cut into configurations according to each part of the piping system such as valves, and the heat insulating material is The covering mat can be used to cover the specified area to be insulated, and a latching part such as a latching gap is formed between a separately prepared fixture and the above-mentioned covering material. A predetermined number of arbitrary parts of the above-mentioned heat-insulating covering mat are fixed with a fixing device to form a heat-insulating covering mat with fixing devices, and the desired heat-insulating construction area is covered with the fixing device-equipped mat, and the above-mentioned fixing device is fixed. By hooking a separately prepared tightening cord material between the mats, the heat insulating covering mat is tightened so that it can be opened and closed.

Therefore, by preparing a heat-insulating covering mat according to the shape and size of the piping system parts such as valves, and tightening the covering so that it can be opened and closed using fixing tools and tightening strings, insulation can be achieved without unnecessary cost and effort. It is possible to carry out construction work.

Further, in the second invention, a suitable tightening means such as a tightening belt is provided on the outer surface of a heat insulating material of a predetermined size and a covering material covering the heat insulating material, and a tightening means such as a suitable tightening belt is provided between a separately prepared fixing device and the covering material.

Since it can be compressed from the outside, a more reliable tightening state can be achieved.

[Example] Next, the present invention will be explained based on FIGS. i1 to 10 showing an example thereof.

Figures 1 to 3 show the combinations of materials for constructing the heat insulating coating mat of the present invention. FIG. 2 is a perspective view showing another heat-insulating covering mat 5 made of a combination of a heat-insulating material 1 and a covering film 4 as another covering material integrally processed with the heat-insulating material 1. FIG. 3 is a perspective view showing a case where the exterior material 2 and the covering film 4 are employed as the coating material, and shows still another matturo for heat insulation coating configured so that the mat 5 for heat insulation coating is covered by the exterior material 2. It is.

The above-mentioned heat insulating material l is glass wool or other heat insulating material with relatively low thermal conductivity, and has a predetermined thickness and large stiffness. Alternatively, it can be cut to any size depending on the shape.

The exterior material 2 is made by forming a porous resin coating with countless micropores on the surface of a cloth made of fibers such as nylon, and the micropores of this resin coating allow only moisture to pass through and water to pass through. This gives the exterior material 2 moisture permeable and waterproof performance. Note that this exterior material 2 may be reinforced using cloth that has been reprinted as a material for rain gear, etc. to give it appropriate elasticity and strength, and may also be made of a glass cloth sheet coated with heat-resistant silicone. The material may be selected depending on the part of the piping system to be insulated and other parts to be insulated. Further, this exterior material 2 is prepared as a long sheet rolled into a roll, and used as appropriate as required.

Furthermore, the covering film 4 is a film made by directly gluing or molding a material such as glass cloth, aluminum/glass cloth, or silicone glass cloth, which is usually thinner than the exterior material 2, onto the heat insulating material 1, singly or in combination. It is assumed that the heat insulating material 1 is made of a material having a shape and is provided on at least one of the front and back surfaces of the heat insulating material l.

In the present invention, any of the above-mentioned heat-insulating covering mats 3°5.6 can be used, and it is appropriate depending on the characteristics 1 of the surrounding environment etc. of the piping system and other parts to be insulated. Select one and use it. For example, although the heat insulation covering mat 3 is generally used in many cases, the heat insulation covering mat 5 is suitable when relatively weather resistance is not required and cost reduction is desired, and when the outdoor or external environment is harsh. Matsutoro for heat insulation coating can be used for this purpose.

For the convenience of the following explanation, we will take as an example a case where a piping system such as a valve is insulated using the heat insulating coating mat 3 shown in FIG. 1. That is, as shown in Fig. 4, the insulation material 1 and the exterior material 2 are used depending on the shape and size of the valves, etc. in the piping system to be insulated and covered.
After cutting, the heat insulating material 1 and the exterior material 2 are stacked on top of each other to form a heat insulating covering mat 3.

Afterwards, the excess side parts and the upper and lower parts of the heat-insulating covering mat 3 are folded up and fixed to a predetermined fixing device, such as a pull-out stopper as shown in FIGS. 5 and 6. 8 to unite each other. Of course, if the size of the heat insulating material 1 is exactly the same as that of the exterior material 2, there is no need to fold it, but it is usually desirable to form the exterior material 2 larger. When folding the side ends of the exterior material 2, the side ends of the heat insulating material 1 can also be folded together, and the side ends of the art material can be fixed in the folded state using the pull-out stopper 8.

As shown in FIG. 6, the removal stopper 8 is composed of a disk 9, a cap 10, a spacer ti formed from an auxiliary ring, and a spindle stud 12. That is, disk 9
As shown in FIG. 5, a small-diameter through hole 13 is formed in the center, and five cuts 1 are formed outward from this through hole 13.
4 are formed at equal angular intervals. As shown in FIG. 6, the removal stopper piece 15 defined by these notches 14 is bulged out into a dome shape on one side of the disc 9, and the outside thereof is covered with the cap 10.

The spindle stud 12 has a head 16 of any shape, such as a disk shape or a rectangular shape, and a needle-shaped portion 17 erected at the center thereof.The needle-shaped portion 17 is inserted into the through-hole 13. The exterior material 2 and the heat insulating material I, that is, the heat insulating covering mat 3 are sandwiched therebetween.

The heat-insulating covering mat 3 is fixed at a predetermined location using such a pull-out stopper 8, thereby forming a heat-insulating covering mat 18 with fixing tools as shown in FIGS. 7 and 8.

In other words, Fig. 7 shows this pine for heat insulation coating with fixtures)
FIG. 8 is a perspective view as seen from the side of the exterior material 2 of 18, and FIG.

In order to fix the exterior material 2 and the heat insulating material 1 together, the removal stopper 8 is fixed to the end of the folded exterior material 2, and if necessary, a heat insulating covering pine with a fixing device is used. ) The end of an arbitrary fixing string material 19 that crosses the center of the mat 18 is fixed with the pull-out stopper 8 along with the exterior material 2 and the heat insulating material 1, so that the heat insulating covering mat 18 with the fixing device maintains its predetermined width. Of course, a plurality of fixing string materials 19 may be provided, and any string material such as wire or cloth material having a predetermined width (both shown in the figure) may be used.

As shown in FIG. 6, the above-mentioned removal stopper 8 is provided with a space for latching as a latching portion by the height of the spacer 11, that is, between the bottom of the disk 9 and the bottom of the spacer 11. The tightening string material 2 is made of the same material as the fixing string material 19 or wire or other arbitrary material.
It is assumed that a gap large enough to hang the o is formed.

In addition, the heat insulation covering mat 1 can be attached using the fixing string material 19.
It goes without saying that the latching portion (latching gap S) formed by the spacer 11 and the like need not be formed if the purpose is simply to maintain the spacer 8 in a predetermined width or shape.

Next, as shown in Figures 9 and 10, cover the part of the piping system to be insulated, for example, the valve B installed at the connecting part of the pipe P, from below, and cover its shaft part A or If so, make the exterior material 2 long so that it covers up to the handle H (the above-mentioned heat-insulating pine with the fixing device)
18, and by hooking the tightening string material 2° between the plurality of pull-out stops 8 in an arbitrary manner, the open portion of the heat-insulating covering mat 18 with fixing devices is closed.

In this way, the whole of the heat-insulating covering mat 3 or the heat-insulating covering mat 18 with fixtures covers the valve B, completing the covering and completing the heat-insulating construction.

By using such a heat insulation construction method and the heat insulation covering mat 18 with a fixture used in this method, the exterior material 2 and the heat insulation material l can be adjusted according to the shape and size of the various valves B and vibes P to be heat-insulated. Furthermore, the heat insulating covering mat 18 with fixtures can be prepared at the work site, and the dimensions can be easily adjusted at that time. Therefore, there is no need to perform sewing at a sewing factory as in the past, which simplifies the preparation for insulation installation work and reduces costs.In addition, the tightening string material 20 can be untied during maintenance and inspection of valve B, etc. By doing so, it is possible to release the heat insulating coating pine with a fixing device 18, and the removal stopper 8
It is also easy to replace the heat insulating material 1 as necessary by removing the heat insulating material 1 or disassembling the heat insulating covering mat 3 by cutting the needle-shaped portion 17 thereof.

Next, in the actual piping system, Figures 9 and 10
Instead of a simple valve B as shown in the figure, there are cases where a handle for operation must be attached to the shaft portion A of the valve B to operate it, as shown in FIG.

Even in such a case, according to the present invention, it can be dealt with immediately at the insulation construction site. Such a case will be explained with reference to an example using the heat insulating covering mat 18 with fixtures described in FIGS. 1 to 10.

That is, as shown in FIG.
A straight line cut 21 of the required length is provided in the longitudinal direction of the heat insulating material l and the exterior material 2 from the peripheral edge inward, and the first
As shown in Fig. 3, by folding the flap 22 formed by the cut 21 outward, the heat insulation covering mat 3
A triangular opening 23 is formed in the opening 23 . Of course, the opening 23 may also be formed in the internal heat insulating material 1, but two insulating materials 1 are prepared in advance, and the opening 23 is formed at the boundary between the two heat insulating materials 1.
3, it is not necessary to provide the cut 21 in the heat insulating material l.

In addition, if the formation of the opening 23 weakens the strength of the torn part, a reinforcing strip 24 may be fixed to the torn part as shown in FIG. 14.

Using the heat-insulating covering mat 3 in this state, construct the heat-insulating covering mat 18 with a fixing tool as explained in FIGS. 4 to 10, and attach it to the valve B as shown in FIG. The opening 23 is arranged so that the handle portion protrudes to the outside and can be operated.

The subsequent work is the same as the above-mentioned work, so the explanation will be omitted, but it is possible to make the handle face the opening 23, and the insulation construction work can be performed despite the presence of the handle. It becomes possible.

In addition, as shown in Fig. 15, if another pipe Q is provided from the main body of the valve B, cross-shaped cuts 25 (Fig. 16) are provided in the necessary portions of the heat-insulating covering mat 3.
By forming the two lower left and right flaps 26, an opening 27 (FIG. 17) is formed.

If the formation of the opening 27 weakens the strength of the torn part, a reinforcing strip 28 may be fixed to the torn part as shown in FIG. 18.

Using the heat-insulating covering mat 3 in this state, construct the heat-insulating covering mat 18 with a fixing tool as explained in FIGS. 4 to 10, and attach it to the valve B as shown in FIG. The opening 27 is arranged so that the piping Q can protrude to the outside.

Since the subsequent work is the same as the above-mentioned work, the explanation will be omitted, but the pipe Q can be made to face the opening 27, and the insulation construction work can be performed despite the existence of the pipe Q. It becomes possible.

In the above-mentioned embodiment, as shown in the sectional view of FIG. 19, the mat 3 for heat insulation coating is fixed by the pull-out stopper 8 as a latching portion by the spacer 11 of the pull-out stopper 8. Although a latching cavity S is formed, the present invention is not limited to this, and modifications as shown in FIGS. 20 and 21 may also be adopted.

That is, the modification shown in FIG. 20 is a pull-out stop 8A in which a hook portion 29A is formed as a hook portion for hooking the tightening string material 20 to the cap IO of the pull-out stop 8 itself. According to this pulling stopper 8A, the same tightening work of the heat insulation coating mat 3 as described above can be performed by hooking the tightening string material 20 to the hook part 29A, but the spacer 11 is omitted. Since it is possible to lower the overall height of the pull-out stopper 8A by that much, it is possible to carry out insulation work without making the entire structure bulky.

Next, in the removal stopper 8B shown in FIG. 21, a hook portion 29Bt is provided at the spacer 11 as a latching portion so as to protrude from the peripheral edge of the cap 10, and the hook portion 29B is tightened. The insulation construction work is performed in the same manner as described above by hanging the cord material 20. According to this removal stopper 8B, it is possible to clearly show the hook portion 29B to the operator, and reliable latching work can be expected.

In addition, in the present invention, the above-mentioned removal stopper 8.8A,
8B can be used as needed or depending on the fixing location of the heat-insulating covering mat 3, and it is also possible to mix and match the removal stops 8.8A and 8B, which are different in size. good.

Next, in the present invention, a heat insulating covering mat 3 or a heat insulating covering mat 5 made of a heat insulating material 1, an exterior material 2, etc.
．． 6. Furthermore, the removal stopper 8 or the removal stopper 8A,
When fixing the heat-insulating covering mat 18 with a fixing device consisting of the removal stopper 8B to the valve B, pipe P, etc., a tightening belt or a tightening ring is provided on the heat-insulating covering mat 3.5.6 as a tightening means. You can also do that.

2nd article about pine) 30 for insulation coating with such fixings
This will be explained based on FIGS. 2 to 26. However, the first
Components that are the same as those in the figures to FIG. 21 are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 22 is a perspective view of the heat insulating coating mat 30 with fixtures as seen from the exterior material 2 side, and FIG. 23 is a perspective view of the same as seen from the heat insulating material 1 side. The mat 30 has a pair of tightening rings 31 provided on its surface side, a central tightening belt 32 that is movably latched onto the tightening rings 31, and a pair of upper and lower shoulder belts 33.
It has 34.

The above-mentioned tightening ring 31 is attached to the heat insulation covering mat 3 by a piece 35, and its diameter can be set according to the size of the valve B etc. to be insulated. It is desirable that the center portion of the tightening ring 31 be located at the center portion of the valve B when the valve B etc. is covered with the valve B.

Note that the tightening ring 31 and the central tightening belt 3
2. The shoulder belts 33, 34 may be attached to the heat-insulating covering mat 3 in advance, or may be attached using the pull-out stopper 8 at the construction site.

Further, the free ends of one pair of shoulder belts 33 are formed into an annular shape, and a pair of square engaging rings 36 and 37 are attached to this annular portion. Therefore, when connecting the shoulder belt 33 and the shoulder belt 34, the 24th
As shown in the figure, the free end of the shoulder belt 34 is passed from the engagement ring 37 to the engagement ring 36, and then the engagement ring 36 is wound up and passed through the engagement ring 37, and the free end of the shoulder belt 34 is passed through the fixed end. By pulling it to the side, the shoulder belt 33 is sandwiched between the engagement rings 36, 37, the shoulder belt 33 and the shoulder belt 34 are connected, and the length of the connection is also adjusted.

Thus, in the same manner as explained based on FIGS. 4 to 10, the heat insulating covering mat 30 with fixtures is constructed,
As shown in Fig. 25, the heat insulation covering mat 3 with fixtures
0 so as to support the valve B from below, and by hooking the tightening string material 20 to the hooking gap S of the spacer 11 portion of the removal stopper 8, the side of the heat insulating covering mat 30 with fixing tool is attached. For the other open parts, connect the shoulder belts 33 and 34 in the manner shown in FIG. 24,
By tightening the shoulder belt 34, the heat insulating covering mat 30 with fixture is fixed so as to cover the valve B.

In addition, during this fixing work, since the tightening ring 31 can press a predetermined area of the heat-insulating covering mat 30 with a fixing device, it is necessary to press the heat-insulating covering mat 30 with a fixing device against the valve B with the necessary pressing force. Therefore, the heat insulation function of covering the valve B by the heat insulation covering mat 30 with the fixing device can be fully exhibited.

Furthermore, since the respective hooking ends of the shoulder belts 33 and 34 can be moved to arbitrary positions on the circumferential edge of the tightening ring 31, the heat insulating covering mat 30 with the fixing device can be moved depending on the shape of the valve B to be covered. Even if the shape changes, the shoulder belts 33, 34 can be moved to the optimal fixing position by following the changes well (see FIG. 26).

In the present invention, as shown in FIGS. 27 and 28, the hooking portion between the tightening ring 31 and the shoulder belt 33 can be configured so that the shoulder belt 33 is removable.

That is, especially as shown in FIG.
The magnetic button 40 is attached to the free end by providing an end 41, and the fixed end 42 of the magnetic button 40 is attached to the part of the shoulder belt 33 opposite to this. The shoulder belt 33 and the tightening ring 31 can be attached by engaging and disengaging the end 41 and the fixed end 42.

After the length adjustment of the shoulder belt 33 and the shoulder belt 34 as shown in FIG. 24 is completed, and the insulation construction is completed, the insulation construction part is inspected or the insulation material 1 is replaced at the same diameter as the predetermined M. At times, the covering with the heat insulating covering mat 30 with a fixture can be easily uncoated, and furthermore, the covering can be immediately completed with the magnetic button 40 in this state, and there is no need to adjust the length again.

As described above, the tightening ring 31 and shoulder belt 33, 34
At the construction site or in advance, heat insulation covering mat 3
If the mat 30 for heat insulation coating with a fixing tool is installed in the mat 30 for heat insulation coating with a fixing tool, the valve B of the mat 30 for heat insulation coating with a fixing tool is the final process of insulation construction of valve B, pipe P, etc. using this mat 30 for heat insulation coating with a fixing tool. Fixing work to etc. can be easily and reliably performed.

In addition, in the present invention, the length of each tightening belt is adjustable, and the shoulder belt 33.3 shown in the above embodiment is adjustable.
Not only the engagement ring 36.3 but also the center belt 32
By providing 7, the length can be adjusted. Of course, this central belt 32 is not essential.

Additionally, the central belt 32 may be provided with a magnetic button 40 as shown in FIGS. 27 and 26.

Further, the configuration in which each tightening belt is detachably attached to the tightening ring 31 is not limited to the magnetic button 40 described above, and any means can be adopted.

Note that the objects to be applied to the insulation construction method according to the present invention are not limited to the above-mentioned embodiments, but include valves, strainers,
It can be applied not only to piping components such as T-joints and flanges, but also to opening/closing parts of insulation boxes, opening/closing parts of awnings, and opening/closing windows of automobile hoods, and even multiple insulation coatings. It is also possible to carry out heat insulation construction by joining mats together, and in this case, the respective heat-insulating covering mats are fixedly connected using the fixing tool.

[Effects of the Invention] As explained above, according to the present invention, a heat insulating material having a heat insulating function and a covering material that protects at least its surface are combined at a heat insulation construction site, and a fixing device such as a pull-out stopper is used. A heat insulating covering mat with fixtures can be constructed according to the parts of the piping system such as valves using
There is no need to measure the dimensions and prepare a heat-insulating covering mat that is sewn in advance at the sewing factory as in the past, and it is now possible to perform highly flexible heat-insulating construction that allows the dimensions of each part to be adjusted according to the on-site situation. In addition, since a latching part is formed in the above-mentioned fixture part, it is expected that the work efficiency will be improved by latching the tightening string material here, which will lead to cost reduction.Moreover, it will be possible to reduce costs during maintenance and inspection of piping systems, etc. Also, the heat insulating covering mat and the tightening means such as the tightening string material can be reused, and it is also easy to replace only the heat insulating material with an arbitrary one if necessary.
