Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a prefabricated insulating panel used for an insulation method for large-sized equipment and tanks, an equipment insulation method using the panel, and a member for a construction method used in the construction method. Regarding

More specifically, chemical equipment such as chemical reactors, crude oil, heavy oil,
Insulation of large heating or cold storage tanks such as asphalt and brine (hereinafter collectively referred to as equipment),
A prefabricated insulation method that does not require a mounting frame when performing heat insulation such as cold insulation and / or vibration insulation such as soundproofing and vibration isolation for vibrating equipment, an insulating panel used in this method, and members for the method. Regarding

[Conventional technology]

Conventional insulation methods for devices include a method of covering the device with a plate-shaped insulating material and a urethane foam method of forming urethane foam on the surface of the device.

The conventional method of using a plate insulation material is to plant support bolts on the surface of the equipment at predetermined intervals and use these bolts to make plate insulation materials (rock wool, glass wool, calcium silicate material, etc.). In addition to mounting, it is tightened with a wire, a wire mesh is stretched on the surface, a water finish material is applied, and finally an outer thin iron plate is stretched. Such a method requires the construction of scaffolding around the equipment,
Moreover, the construction period is long and the cost is high.

As a urethane foam method, apply rust preventive paint to the equipment surface, spray urethane foam on it, protect this urethane foam layer with a fireproof coat, and then apply surface paint on it, scaffolding There is a method in which an exterior plate is stretched over a certain distance from the equipment surface and urethane is injected and foamed between the exterior plate and the tank.

The former has the advantage of not needing to build a scaffold, but since the urethane foam layer is in direct contact with the surface of the reversing device, it has the disadvantage that the urethane foam layer will crack due to expansion and contraction of the device, and during rain. However, rainwater is easily absorbed by the urethane foam layer, and in extreme cases, the equipment surface may be corroded. Also, the foam layer cracks and rainwater is absorbed to soften the urethane, and the equipment often expands to cause "blister" in the urethane.

The urethane injecting method has the same drawbacks as the urethane spraying method, and more scaffolding needs to be installed.

As a prefabricated insulation method in which the drawbacks of the conventional construction method can be eliminated and construction can be performed without erection of scaffolding, and an insulating material is attached to the exterior plate at the factory.
41,964, JP-A-52-43,115, and JP-A-54-2,566 are known.

All of these are provided with a frame for mounting a panel or a panel suspension device fixed to the main body of the device, and the panel is attached to the frame or the panel is suspended.

[Problems to be Solved by the Invention]

When installing a prefabricated insulating panel in which a plate-shaped insulating material is attached to the exterior material at the factory, it is possible to plant support bolts on the equipment surface and mount it with this, just as the above-mentioned plate-shaped insulating material is mounted. . However, the outer panel of the equipment is manufactured by the can making work, and even if it looks like a certain shape when viewed from a distance, it is inevitable that there are subtle unevenness and local deformation, and the thickness of the board is also thick. Since the device is thin, even when the device is empty, such as an empty tank, the large device is deformed by expansion and contraction due to temperature and various other external forces.

Therefore, even if holes are drilled at predetermined locations on an insulating panel that has been prefabricated in the factory and the support bolts are planted according to the dimensions, the holes will be misaligned during actual mounting and cannot be mounted. There was a problem.

Therefore, like the plate-shaped insulating material attachment method, a scaffold is required to stretch the exterior plate at the site, the construction period becomes long and costly, and the urethane foam layer has cracks like the urethane method, Even if the problem of softening or blistering due to rainwater can be solved by preliminarily attaching an insulating material to the exterior plate in the factory, there remains a problem in mounting this prefabricated insulating panel.

In each of the above publications, a frame of a frame is separately formed on the outside of the device, a position correcting mechanism such as a long hole or a moving bolt is provided in the frame, or the panel itself can be moved left and right like suspension. And deal with it.

However, making a separate skeleton on the outside of this equipment is costly and time-consuming, if not necessary for scaffolding.

However, it is difficult to attach the skeleton itself to a device having reinforcing ribs or other protrusions, apart from a device such as a tank having less irregularities on the outside.

It is an object of the present invention to provide a method of attaching a pre-bab insulating panel in which an insulating material is attached in advance to an exterior material to a device in a factory without requiring any skeleton.

Moreover, although the technique described in the above publication can be achieved to some extent, further shortening of the on-site construction period, no need for scaffolding installation, no influence by expansion and contraction of equipment, insulation by two insulating layers of air layer and insulating panel Great effect, uniform insulating layer can be maintained, safe use temperature can be raised even with low heat resistant insulating material, no adverse effect due to intrusion of rainwater, exterior is elegant and robust To provide a construction method that simultaneously achieves the following objectives: easy inspection and repair after construction, and safety against fire.

In the technology described in the above publication, the air layer between the device outer plate and the insulating material is determined when the frame is constructed, but the present invention provides a construction method in which the thickness of this air layer can be adjusted. With the goal.

When a device generates noise, not only the insulating panel of the prior art does not have a soundproof function, but also the noise is increased. However, in the present invention, the insulating panel has a vibration insulating function, that is, a soundproof function. The purpose is to provide a possible construction method.

[Means for Solving the Problems]

The present inventors have conducted research to solve the above problems, prefabricated prefabricated insulating panel in which a mounting rod receiving member is fixedly pierced through a panel in a factory, and abutting the panel on a mounting location of a device. The present invention has been completed by finding that the problem can be solved by fixing the tip of the mounting rod to the device from the outside of the panel and mounting the insulating panel to the device through the mounting rod.

That is, the present invention is a mounting rod composed of an internal hollow body having a flange portion at one end and a tightening member mounting portion at the other end of a panel made of an insulating core material and an exterior material or an exterior material and an interior material, and a tightening member. A prefabricated insulating panel formed by integrally fixing a receiving member through it. As a construction method, the insulating panel is brought into contact with a predetermined position of a device to be mounted, and the inside of the mounting rod receiving member of the internal hollow body attached to the panel is attached. The panel is mounted by penetrating it to electrically, thermally and vibrationally insulate the mounting rod from the mounting rod receiving member, and by fixing the tip of the mounting rod to the device so that it does not come into direct contact, and so on. This is an equipment insulation method characterized in that prefabricated insulation panels are sequentially attached to the equipment surface in a state of being adjacent to each other.

A method of fixing the tip of the mounting rod to a device or a rib on the surface of the device is to bring the insulating panel into contact with a predetermined position of the mounted device, and then from the outside of the panel into the mounting rod receiving member of the internal hollow body made of metal. The mounting rod is electrically, thermally and vibrationally insulated, and is inserted so as not to vibrate directly, and electricity is applied between the mounting rod and the device or a rib attached to the device, and the tip of the mounting rod is attached. Is fixed to the equipment by welding, and the panel is attached to the equipment by pressing the attachment rod receiving member that attaches the tightening member to the outer protruding portion of the attachment rod. It is a device insulation method characterized by sequentially mounting the devices on the surface in an adjacent state.

In addition, the prefabricated insulating panel is brought into contact with a predetermined position of the mounted device, and a self-threaded screw is thermally and vibrationally insulated from the outside of the panel and inserted into the mounting rod receiving member of the internal hollow body. The screw is attached to the device by rotating the screw while pressing the tip of the screw into the device, attaching the screw to the device, and pressing the receiving member by the head of the screw or the tightening member fitted to the screw. This is a device insulating method in which the panel is mounted on the device so that the device does not come into linear contact with the mounting rod receiving member, and then the prefabricated insulating panels are sequentially mounted on the device surface in the adjacent state.

In the device insulation method, the mounting rod receiving member itself is projected inward, or a spacer of a predetermined length is attached to the inner end of the mounting rod receiving member, and the mounting rod is inserted into the mounting rod receiving member from the outside of the panel. Then, when the tip of the mounting rod is fixed to the device and the receiving member is pressed by the outer protruding portion of the mounting rod or the tightening member attached to the protruding portion, the tip of the spacer is pressed against the outer surface of the device to insulate the insulating panel. It is a device insulation method characterized in that the device is mounted on the device while maintaining a predetermined gap between the inner surface of the panel and the outer surface of the device.

The mounting rod receiving member to be mounted on the insulating panel is a member for an insulation method including an inner hollow body having a bulge portion at one end and a tightening member mounting portion at the other end, and a tightening member.

As a device insulating method member, a mounting rod receiving member of an internal hollow body that is fixed by penetrating the insulating panel, a spacer formed at the tip of the receiving member inside the panel, and a penetrating through the receiving member. And a mounting rod that electrically and thermally and vibrationally insulates the receiving end from the receiving member, and a tightening member that is mounted on the head portion or the protruding portion outside the panel of the mounting rod. It is a member for the insulation panel mounting method.

As the spacer to be attached to the insulating panel, the tip of the protruding portion inside the panel of the mounting rod receiving member of the inner hollow body that penetrates through the insulating panel at a plurality of positions and tightens the insulating core material of the panel and at least the exterior plate is fitted. A spacer having a fitting hole formed at one end and a projecting body in contact with the outer panel of the mounted device at the other end, and the tip of the mounting rod that penetrates the mounting rod receiving member from the outside of the panel is attached to the device. It is an insulating panel mounting method member that is fixed and holds a predetermined distance between the equipment surface and the inner surface of the panel when the panel is pressed from the other end through the mounting rod receiving member.

The prefabricated insulation panel according to the present invention is integrated by adhering the exterior material to the insulation material with an adhesive, or by attaching the exterior material to the insulation material and piercing and fixing at a plurality of locations with a sleeve such as a mounting rod receiving member described later. Needless to say, it is more preferable to combine these means, such as attaching them by tacking at a plurality of points to integrate them, or adhering and fixing at a plurality of points with a sleeve.

When only attaching the exterior material to the insulating material, when attaching the mounting rod receiving member or tack, etc., attach the washer or disc to the inside insulating material with a large area. The receiving member is attached to the insulating panel by a tightening member fitted on the protruding portion.

When the insulating material is a rigid insulator such as calcium silicate or foamed phenol resin, the mounting rod receiving member can be firmly attached only with the insulating material and the exterior material, but as the insulating material, a flexible material such as rock wool or glass wool can be used. When using an insulating material, it is preferable to further attach an interior material. By mounting the interior material, the rigidity of the insulating panel as a whole is increased, making it easier to handle, such as when standing upright, and the mounting rod receiving member can be attached to the insulating panel more firmly. It is possible to prevent the moisture from entering the insulating material.

From the appearance, a colored iron plate or the like can be preferably used as the exterior plate, but any thin metal plate can be used. Also as the interior plate, it is desirable to attach a thin metal plate, preferably a thin zinc iron plate, a thin aluminum plate or the like.

The insulating panel is preferably a corrugated steel plate, a square wave iron plate, or the like with an insulating material bonded to an exterior plate provided with grooved folds in the longitudinal direction in order to provide rigidity in the longitudinal direction.

The exterior plate completely connects with the adjacent panel, and in order to prevent rainwater from entering, one edge of the square wave protrudes outward at the end of the short side, and one edge of the square wave inwards on the opposite side. When they are mounted adjacent to each other, the angular waves overlap each other to complete the connection between the panels and prevent rainwater from entering.

Also in the vertical direction of the exterior plate, the exterior plate is protruded downward from the insulating material and overlapped with the lower insulation panel.

Any insulating material such as rock wool, glass wool, calcium silicate, foamed phenolic resin, urethane foam can be used as the insulating material, but inorganic fibers such as rock wool and glass wool are bonded especially in the direction perpendicular to the exterior plate. However, an insulating panel is preferable because it has strength in each direction and has high heat resistance.

The above-mentioned various methods can be used to attach the exterior material and the interior material to the insulating material, but it is preferable to use the adhesive method as a basis and to use other methods together.

Through holes for mounting the mounting rod receiving member to the insulating panel are, for example, an exterior plate having a width of 800 mm and a length of 2,000 mm, two places in the width direction and three places in the length direction, a total of six places, a width of 400 mm,
If it is a small exterior plate with a length of 1,000 mm, it will be 2 to 4 in the width direction, 1 or 2 in the center, and 2 in the length direction.
It is preferable to provide a number of places. This is of course determined by the size of the plate and the weight of the insulating panel.

The attachment rod receiving member is a hollow sleeve having a sleeve shape.
It is preferable to use one end as a fixed flange and thread the other end, and tighten a nut, speed washer, or other tightening member to tighten it from both sides of the exterior plate and the interior plate. Alternatively, the tightening members may be tightened from both sides, or an adhesive may be used instead of the tightening members to fix them. A circular tube is preferable for the convenience of manufacture and acquisition, but the present invention is not limited to this, and a square tube or other polygonal tube may be used. Two fixed pipes may be welded with a circular pipe, one of which may be a male screw and the other of which may be a female screw so that they are joined at the center of the insulating material. When the insulating material has rigidity, the circular pipes with flanges may be fitted from both sides and the central portion may not be joined. It is also preferable to provide a rib on the lower surface of the bottom of the flange for the purpose of preventing the rotation together with a tightening member such as a nut when it is fixed to the panel. Also, when mounting the mounting rod receiving member from both sides of the panel, when tightening by rotating the nut etc., cut the opposite edges of the flange in parallel to prevent co-rotation and hold the flange at this parallel part and tighten the nut etc. It is preferable.

Although it is cost-effective to use a metal tube, particularly a steel tube as a material, a plastic tube, a rubber tube, a ceramics tube, or the like can also be used.

In particular, when the tip of the mounting rod is fixed to the equipment by welding, electricity is supplied from the panel outside portion of the mounting rod. Therefore, when a metal pipe is used, it is preferable to apply a lining such as rubber lining or plastic lining to the inner surface. Instead of the lining, when energizing the mounting rod, a rubber tube, a plastics pipe, or the like may be fitted or fitted around the mounting rod. A ring-shaped body of an electrical insulator such as rubber may be adhered to the mounting rod itself or the mounting rod receiving member at a portion of the panel outside and in the vicinity of the inside where there is a possibility of contact. Of course, if the mounting rod receiving member itself is made of plastic such as nylon, rubber or ceramics, such consideration is not necessary. Such a material has an advantage that a square tube or the like can be manufactured with the same number of steps as a circular tube, which is advantageous in preventing co-rotation.

When fixing the mounting rod to the equipment by a method other than current welding,
Such consideration is unnecessary, and the material of the mounting rod receiving member may be considered only mechanical strength.

The role of the mounting rod receiving member is to maintain the strength when the prefabricated insulating panel is manufactured in the factory and is transported and stored at the insulation construction site.

This is because, if the outer plate and the inner plate are simply bonded to the insulating material, only the insulating material connects them to each other, and the strength is insufficient in the case of a flexible insulating material such as rock wool or glass wool.

The second role is to maintain a sufficient gap between the mounting rod and the mounting rod receiving member.

The inner diameter of the mounting rod receiving member is 1.3 to the outer diameter of the mounting rod itself.
About 3 times as large as the outer diameter of the mounting rod. This copes with expansion and contraction due to temperature changes of the equipment and panel due to temperature changes during equipment operation, and when the surface of the equipment is inspected and the insulation panel is removed, variations in dimensions between panels,
This is to allow play around the mounting rod in order to deal with deformation and the like.

The third role is to make the insulating panel soundproof and antivibrating. Since the conventional insulating outer plate is fixed to the equipment or the frame, not only the effect of soundproofing and antivibration but also the width of the insulating material is increased. The mounting rod receiving member of the present invention has a gap between it and the mounting rod, and in order to have a vibration-proof effect, the inner surface of the mounting rod receiving member is lined or fitted with rubber or resin having a vibration damping effect. be able to.

The mounting rod comes into contact with the mounting rod receiving member at the time of expansion / contraction of the equipment in operation as described above, removal of the insulating panel, and reattachment even if a gap is initially provided between the mounting rod and the mounting rod receiving member. Because there is a possibility.

Even when a panel is tightened by attaching a tightening member to the part where the mounting rod protrudes from the exterior plate, it is prevented that the elastic member such as a rubber washer is used between the tightening member and the flange of the mounting rod receiving member. It is preferable to shake up.

The fourth role is to utilize the end of the mounting rod receiving member inside the insulating panel as a spacer mounting terminal. Not only in the case of an insulating panel in which an exterior plate is attached to an insulating material, but also when an interior plate is further attached to this, the inner layer plate is a thin plate with a thickness of 0.5 mm or less, so it is not suitable for spacer attachment. Appropriate.

For the purpose of not attaching a frame or the like for mounting an insulating panel to the device, it is necessary to install a spacer inside the insulating panel if an insulating air layer is to be secured between the device and the device. The end of the mounting rod receiving member inside the insulating panel can be a perfect spacer mounting terminal. The mounting rod receiving member sandwiches the insulating material in a sandwich shape, tightens both the exterior plate and the interior plate, grasps the insulation panel firmly, and maintains the verticality to the equipment surface. is there.

If a thin air layer between the equipment and the equipment is sufficient, the inner end of the mounting rod receiving member should be projected inward for a certain length without the need to attach a spacer, and the spacer function should be fulfilled. You can also

The attachment rod is a rod-like body having one end fixed to the surface of the device, penetrating the attachment rod receiving member, and having multiple ends protruding from the insulating panel. Generally, a steel rod or the like is preferable in terms of cost. When protruding from the insulating panel, a locking part such as cutting screws to press the panel toward the equipment is provided by tightening members such as nuts and speed washers by sandwiching washers and rubber washers.

As a material, insert the mounting rod from the outside of the insulation panel,
When the tip is brought into contact with the equipment and electric current is applied from the outside to weld the tip, a metal rod is required. A steel rod is preferable from the viewpoint of welding. A self-threaded screw can also be used as this mounting rod. A self-threading screw is a self-drilling tapping screw that is a long screw with the tip of the drill having the shape of a blade at the tip of the drill and the tapped screw with the hole of the drill diameter as the lower hole. It is a long steel screw that has the hardness that is required to cut the device by itself at the screw part.

If the equipment is thin and does not fit well in welding or self-threading type screws, and the temperature does not become so high, attach the tip of the mounting rod with a quick-curing adhesive such as an instant adhesive. May be. In this case, as the material of the mounting rod, there is no restriction on the material as long as it has adhesive strength with the adhesive and is satisfactory in strength. Further, in order to fix the tip of the attachment rod to the device, the tip may be pressed against the device and ultrasonically welded to the external terminal to weld the tip by ultrasonic welding. Also in this case, the material of the mounting rod is arbitrary.

As described above, the spacer is a spacer for keeping an air layer having a constant thickness between the inner surface of the insulating panel and the surface of the device. The shape may be any shape as long as one end can be attached to the panel inner end of the attachment rod receiving member and the other end can abut substantially perpendicularly to the surface of the device.

When the tightening member such as a nut is tightened on the panel outer protruding portion of the mounting rod by rotation, the mounting rod receiving member may also rotate, so that a member having rigidity against the rotational force is preferable. A steel plate is formed into an inverted U shape, and a hole is formed in the top so that the inner end of the mounting rod receiving member can be fitted, or a screw is cut on the inner end and a female screw corresponding to this screw is cut. It is preferable (FIGS. 1 and 8).

A tubular spacer having a cap nut welded to the screw at the inner end of the mounting rod receiving member is also preferably welded to the tip of the steel pipe (Fig. 2).

Further, a hole or a female screw into which the inner end portion of the mounting rod receiving member is fitted is cut in the central portion of the plate-like member, and the ring-shaped portion surrounding the hole of the plate-like member has a thickness of air layer between the device and the panel. It may be an inverted Gotoku-shaped spacer with corresponding legs attached by welding or the like.

In this case, it is more preferable to weld a ring-shaped slide plate to the device contact portion so as to withstand the rotation during the tightening.

A spacer in which a block body of plastic such as nylon is attached to the inner end of the mounting rod receiving member, a plurality of holes are bored in the block body, and a rod-like body for implanting a device is also implanted (FIG. 3). ). The shape of the block body is an ellipse or a rectangle in the case of two bars, an equilateral triangle in the case of three bars, a regular quadrangle in the case of four bars, etc. in order to ensure an even wall thickness around the holes. Is preferred (FIGS. 9 and 10).
In this case, the thickness of the air layer between the insulating panel and the equipment surface can be easily adjusted by replacing the rod-shaped body with a different length.

According to the conventional method in which the mounting rod is preliminarily welded to the equipment outer plate in accordance with the arrangement dimension of the mounting hole of the insulating panel, the equipment outer plate which is a can-making product is strained, and expansion, contraction due to temperature change,
Because the mounting rod is not always welded vertically and the size of the insulating panel itself fluctuates, even if the first panel matches the mounting hole, it gradually shifts in position. There will be a gap.

In the present invention, the adjacent panel and the exterior plate angular wave portion that have been sequentially mounted are overlapped and continuous to prevent entry of rain or the like,
In this way, the insulating panel is attached to the device position that is determined by the connection relationship with the insulating panel, and the inner end of the rod receiving member or the tip of the spacer is abutted against the outer surface of the device. Insert the mounting rod into the tube from the outside of the panel, fix the tip of the mounting rod to the device, and attach the mounting rod to the panel outer surface protrusion through rubber washers, washers, etc.
Mount the panel by pressing the panel toward the equipment with tightening members such as nuts and speed washers.

This is the most essential part of the present invention. This eliminates the problem of misalignment and eliminates the need for frame and frame for panel mounting.

The case where the tip of the attachment rod, which is the most common in the present invention, is welded by externally applying electric current will be further described.

When the insulating panel comes into contact with a predetermined position on the outer surface of the device, a steel rod is inserted from the outer surface of the panel through the attachment rod receiving member until it comes into contact with the outer surface of the device. At this time, the inner surface of the mounting rod receiving member is provided with a rubber lining, or a rubber tube is fitted and the mounting rod is inserted when the mounting rod is inserted to electrically insulate the mounting rod from the panel. Of course, this is not necessary if a mounting rod receiving member made of plastic such as nylon is used. The mounting rod is preferably a steel rod provided with an engaging portion such as a screw on the protruding end portion outside the panel.

An electric current is applied between the outer protruding end of the mounting rod and the device, and the tip of the mounting rod is welded to the surface of the device. Then, a tightening member such as a rubber washer, a washer, and a nut is tightened on the outer protruding portion of the mounting rod to mount the mounting rod receiving member, and thus the insulating panel, to the device.

If a self-threaded screw is used as the mounting rod, of course, no electrical insulation means is needed. However, when imparting vibration-proofing capabilities such as soundproofing, it is necessary to take measures such as fitting a rubber lining or a rubber tube.

The same applies to the case where the tip of the mounting rod is fixed to a device with a quick-curing adhesive such as an instant adhesive, or the case where it is fixed by ultrasonic welding.

When providing an insulating air layer between the insulating panel and the equipment,
Except when there are ribs on the outer surface of the equipment and it is possible to maintain an appropriate interval by this, attach a spacer to the inner end of the mounting rod receiving member, and tighten the external protruding part of the mounting rod with a tightening member. The spacer is pressed against the surface of the device via the receiving member, so that the insulating panel can be mounted in a state in which a constant space is maintained between the panel and the surface of the device.

When a self-threaded screw is used as the mounting rod, there is an advantage that sparks or the like are not generated during construction and the construction can be performed even in a work site where fire is strictly prohibited.

In this way, a large number of insulating panels are sequentially mounted on the outer surface of the equipment in a state of being adjacent to each other, but rainwater is sufficiently infiltrated by the overlapping of the angular waves in the width direction and the protrusion of the exterior plate downward in the length direction. Can be prevented.

If necessary, it is called a joiner between the upper insulation panel and the next lower insulation panel. The upper half is made of a colored iron plate that covers the inside of the upper insulation panel and the lower half covers the outside of the lower insulation panel. It is also possible to completely prevent the intrusion of rainwater by inserting the bent plate body. But this is not mandatory.

Of course, the upper and lower ends of the air layer between the insulating panel and the device outer plate are sealed with an insulating waterproof material to prevent air flow. If necessary, dry air can be passed through this portion to dry the outer plate and the insulating material.

〔Example〕

Insulation panels are manufactured up to this shape in the factory and transported to the work site.

FIG. 1 is a cross-sectional view (partially, the upper part of the mounting rod receiving member and the protruding part of the mounting rod are shown in an elevation view) for explaining the insulating panel mounting method which is the core of the present invention. Exterior plate 1, insulating material 2,
Mounting rod receiving members 4 penetrate through the interior plate 3 at six places, and are fixed by screws 6 and speed washers 7 cut on the side opposite to the flange. An inverted U-shaped spacer 15 is screwed into the protruding portion of the screw 6 on the insulating panel carried to the insulating work site in this form, and the worker who rides on the gondola in front of the device 1 is a suction type gripping machine (not shown). The insulating panel is gripped by and brought into contact with a predetermined portion of the device.

In this state, the mounting rod 9 is inserted into the mounting rod receiving member 4 from the outside of the panel, and the tip thereof is brought into contact with the surface of the device. A rubber lining 8 is provided on the inner surface of the mounting rod receiving member. An electric current is applied between the external protruding end 9 ′ of the mounting rod and the device 13 to weld the tip portion 14 of the reception rod 9 to the device. The mounting rod receiving member is tightened with the nut 10 via the rubber washer 12 and the washer 11 to the outer protruding portion 9'of the mounting rod of the outer flange 5. Then, the mounting rod receiving member 4 becomes the spacer 15
Then, the device 13 is pressed via the, so that the insulating panel is attached to a predetermined position on the surface of the device.

FIG. 8 is a perspective view of the inverted U-shaped spacer.

FIG. 4 shows a case where a self-threading type screw (self-drilling tapping screw, trade name Tex screw) 21 is used as a mounting rod. The same is true up to the point where the insulating panel is brought into contact with a predetermined portion of the device via the inverted U-shaped spacer. Needless to say, an electrically insulating work such as a rubber lining is unnecessary for this mounting rod receiving member unless vibration-proof construction is desired. Self-threaded screw 21 with nut 2

The mounting rod receiving member 4 is fixed to the inner end of the panel with a nut 25. On the upper portion of the inverted U-shaped spacer, a hole through which the end portion penetrates is formed, and this hole is fitted to the end portion and fixed by a speed washer 26.

Although the self-threaded type screw 21 is used as the mounting rod,
The external projection length is used to determine the depth of screwing into the equipment. When the screw has been screwed to a predetermined depth, tighten the nut 24 to attach the mounting rod receiving member through the washer and rubber washer, and thus the spacer. Press on the device. As a result, the insulating panel is attached to the device.

〔The invention's effect〕

The insulating panel, the device insulation method using the panel, and the member for the method of the present invention have various effects as described below.

(1) Shortening of on-site construction period: All the prefabricated insulating panels to which the mounting rod receiving members used in the present invention are fixed are prefabricated in a factory or a work place in advance, and the prefabricated construction method is to bring them to the site for assembly. , The construction period at the site is significantly shortened.

(2) No need to attach a frame or a mounting frame: The frame and the mounting frame, which were the biggest drawbacks of the conventional equipment insulation method, are unnecessary,
It can be attached directly to the equipment outer plate at a desired location without displacement, further shortening the construction period on site.

(3) No need for scaffolding: Since it is a prefabricated construction method and does not require a skeleton, it can be constructed by workers on the gondola, and scaffolding that requires cost and labor is unnecessary.

(4) Unaffected by thermal expansion and contraction of equipment: The insulating panel of the present invention is stretched a little apart from the equipment outer plate even with the smallest spacer, and there is no play gap between the mounting rod and the pipe. Since it is provided, it expands like a thing that sprays or injects urethane foam directly on the equipment surface,
Shrinkage does not cause cracks.

(5) Extremely high thermal and vibration insulation effect: There are two insulation layers, an air layer and an insulation panel, between the outer surface of the equipment and the outside air, and the air layer is sealed. Shows an extremely excellent insulating effect. In addition to thermal insulation, by using a rubber material that has a vibration damping effect between the mounting rod receiving member and the mounting rod, it has a sound insulation and vibration insulation effect even when the equipment vibrates. .

(6) Uniform insulating layer: Conventionally, when urethane foam is used as an insulating material, in-situ foaming or injection method may cause surface irregularities or air voids in the foam due to external conditions such as temperature, humidity and wind. There is. Since the present invention is molded in the factory even when using Uretafoam as the insulating material,
The surface is smooth and a uniform insulating layer is obtained.

(7) Expansion of safe operating temperature: Since there is a space between the insulation panel and the surface of the equipment, it is possible to use insulation materials with low heat resistance that could not be used in the past where insulation materials were in direct contact with equipment. A material that originally has a high heat resistance temperature, such as rock wool, has a higher safe use temperature and a wider use range.

(8) No adverse effect due to rainwater intrusion: It is weak against rainwater by the conventional urethane construction method, etc. and may absorb rainwater in the foam, causing equipment corrosion, and absorbing water increases heat conductivity. Although the insulation effect was hindered, in the present invention, since the colored iron plate is used as the exterior plate, even when urethane is used as the insulating material, there is no risk of rainwater absorption, and therefore there is no risk of equipment corrosion.

(9) Exterior is elegant and robust: If the exterior plate is a colored iron plate, the appearance is elegant and it is extremely robust because it is fixed to the device body.

(10) Easy inspection and repair after construction: In the present invention, 1
After installation, it can be easily removed by removing the tightening member of the mounting rod.Therefore, when inspecting the outer surface of the equipment according to the Fire Service Act or replacing the damaged panel, the panel is standardized, and the mounting rod By providing play around, inspection and repair are easy and economical.

(11) Economical construction cost: In the present invention, construction of scaffolding and skeleton are not required, and the construction cost can be greatly reduced by improving efficiency by prefabrication and shortening the latter period.

(12) Safe against fire.

Even if a flammable material is used as an insulating material, the insulating plate of the present invention is entirely covered with an iron plate, is strong against fire, and is a very effective construction method for disaster prevention. In particular, when a self-threaded screw is used as the mounting rod, or when the tip of the mounting rod is fixed by an adhesive or ultrasonic welding, the construction can be performed even in a place where fire is strictly prohibited.
