Abstract

PURPOSE:To aim at simplifying and promoting the laying of a heat-insulator, by attaching a base member having its outer surface from which securing check rods having a length shorter than the thickness of the heat-insulator are projected, onto the outer surface of a structure, and by securing the heat-insulator on which an adhesive agent is coated, to the back surface of the base member. CONSTITUTION:The front end of a securing rod 2 is sharpened, and a locking member 3 is formed in the barrel section of the rod 2 so that the member 3 is projected in the direction crossing the axis of the rod 2, in such a check-like shape that a material which has been at once impaled thereonto cannot come off. An insulator 1 whose outer surface is coated on the adhesive surface of an insulator 1 with an adhesive agent 6 is pressed onto the outer surface of a base material 5 on which securing rods 2 are planted. Thereby the adhesive surface of the insulator 1 on which the adhesive agent 6 is coated is made into contact with the outer surface of the base member 5 while the securing rods 5 are stabbed into the insulator 1, thereby the locking members 3 of the securing rods 2 prevent the insulator 1 from peeling off.

Description

[Detailed description of the invention] The present invention relates to a method for installing a heat insulating material.

When constructing a low-temperature liquid storage tank, etc., insulating material is installed on the wall of the tank to keep it cool.

Currently, this insulating material is attached to the tank wall using adhesive or bolts, but these attachment methods have the following problems.

<A> When using adhesive, wait until the adhesive hardens.
It is necessary to continue pressing the insulation material against the wall for a long period of time.

In order to press down the insulation material, the insulation material was pressed down by passing a wire or by installing a tube that expanded with air.

Therefore, it takes time and effort to install the tubes and tubes.

〉Continuing to insert the adhesive for a long time until it hardens makes the work inefficient and increases the cost, especially when the heat insulating material is laid over a wide area of 5,000 to 6,000 Tl12.

<C> In particular, in the method of forming a continuous insulation material by welding adjacent individual insulation materials by heat, the balance between the progress speed of the adhesive bonding work and the heat welding work is lost.

In other words, the bonding work ends when the adhesive hardens, whereas the heat welding work ends within a short time.

Therefore, the first period tends to be longer because the heat welding work is interrupted or the progress of the welding work is delayed in conjunction with the adhesion work.

(2) In addition, when bolts are used, the insulation material is passed through the bolts, so the bolts conduct heat and reduce the insulation effect.

The present invention has been made to solve the above-mentioned problems, and provides a method for installing a heat insulating material that is easy to install, shortens the construction period, and does not adversely affect the heat insulating effect. aim at something.

That is, in the present invention, a base material having a group of check-shaped fixing rods protruding from the surface that is shorter than the thickness of the heat insulating material is attached to the surface of the structure, and the heat insulating material coated with adhesive on the back side is attached to the base material with the contact surface as described above. This relates to a method of installing a heat insulating material, in which the heat insulating material is fixed by pressing the fixing rod against the surface of the base material and positioning the tip of the fixing rod within the heat insulating material.

Next, a case in which a heat insulating material is installed in a storage liquid tank for low temperature will be explained, but first, each member used in this example will be explained.

[A] Insulating material As the insulating material 1, a known material having a very low thermal conductivity, such as polyurethane, is used.

The heat insulating material 1 has an appropriate thickness T and is formed into a band shape or a rectangular single piece.

[Opening] Base material The base material 5 is a film body made of, for example, a metal film or other material.

Two groups of fixing rods are provided on the surface of the base material 5 so as to protrude in a direction perpendicular to the base material 5 or inclined in one direction.

[C] Fixing rod The fixing rod 2 is a rod that is inserted into the heat insulating material 1 to press the heat insulating material 1 to the wall surface on which it is to be installed, and is made of metal, synthetic resin, wood, etc. do.

The tip of the fixing rod 2 is formed to be sharp, and a locking body 3 is provided on the body to protrude in a direction transverse to the rod axis to form a non-returning shape that prevents an object from being handled once it is pierced.

As shown in FIG. 4, the total length of the fixing rod 2 is such that it does not exceed the thickness T of the heat insulating material 1 described above in order to prevent heat conduction by the fixing rod 2.

It is also conceivable to use a type of fixing rod 2 in which a plurality of locking bodies 3 are formed in succession in the axial direction, as shown in Figs. 5 and 6, or a type in which prismatic arms are protruded. .

In short, it is sufficient that the fixing rod 2 has a shape that can prevent the heat insulating material 1 from retreating once the fixing rod 2 penetrates into the heat insulating material 1.

Next, a method of installing the heat insulating material 1 will be explained.

[B] Fixing the base material 4 shown in FIG. 2 is a wall made of concrete, for example.

An airtight material is attached to the installation surface of the heat insulating material 1 of this wall body 4. Paste the base material 5 on the entire surface.

As described above, the base material 5 used has the fixing rods 2 planted in advance at appropriate intervals on its surface. As a result, the wall body 4 is provided with a fixing rod 2 with a large number of pointed portions facing outward.
is exposed.

In some cases, the fixing rod 2 may be installed after the base material 5 is attached first.

[Opening] Apply adhesive 6 to the adhesive surface of temporary insulation material 1, and then
is pressed onto the surface of the base material 5 on which the fixing rod 2 is planted.

As a result, while the fixing rod 2 is inserted into the heat insulating material 1, the adhesive surface of the heat insulating material 1 coated with the adhesive 6 comes into contact with the surface of the base material 5, and the locking body 3 of the fixing bar 2 causes the adhesive surface of the heat insulating material 1 to come into contact with the surface of the base material 5. Peeling is prevented.

Therefore, the heat insulating material 1 is temporarily fixed to the base material 5 while maintaining the pressing force from the moment it is pressed, even though the adhesive does not harden immediately.

[C] Adhesive When the adhesive hardens, the heat insulating material 1 is completely fixed to the base material 5.

Even at that time, the fixing rod 2 continues to function as a member to prevent the heat insulating material 1 from peeling off and to prevent it from sagging.

Since the present invention is as explained above, the following effects can be expected.

<A> Since a base material with fixing rods protruding from the surface is used, construction can be simplified and speeded up.

Since the fixing rod provides a constant pressure on the insulation material until the adhesive hardens, there is no need to attach or remove a pressing means that presses from the outside of the insulation material as in the past.

Therefore, not only the work is simplified, but also one period can be shortened.

<C> Since the fixing rod is positioned without being exposed on the inner surface of the heat insulating material, heat conduction by the fixing rod can be prevented.

Therefore, there is no need to worry about the heat insulating effect of the heat insulating material being adversely affected.

<2> Although the heat insulating material can be sufficiently fixed using the fixing rod alone, the fixing force of the heat insulating material was improved by using the fixing rod and adhesive together.

<E> Since the heat insulating material is temporarily fixed by the fixing rod, the heat insulating material can be installed without being affected by the curing speed of the adhesive.

Therefore, even when thermal welding is performed to continuously lay the heat insulating material over a wide area, the welding can be carried out with high efficiency.

<F> It can be used not only for installing insulation materials, but also for installing other known materials in various structures, making it highly versatile.
