Abstract

PURPOSE:To enable to attach heat-insulating panels to the surface of a wall even if the wall is weak, by attaching a purality of heat-insulating panels constructed in a flat form to the surface of a wall with an adhesive being applied to the circumferential part and a surface material being attached to the central part, and hardening the adhesive by applying compressive force from the entire circumference of the panel structure. CONSTITUTION:A mastic material 5 such as hot asphalt is applied over the surface of panels 1a, 1b and a surface material 6 of kraft paper or the like is attached to the surface of the panels 1a, 1b. The heat-insulating panel structure is constructed by attaching a required number of panels 1b onto the surface of the panels 1a by use of an adhesive 2, and one row of panels 1c applied with an adhesive 8 are attached to the outside of the panels 1a, 1b and required compressive strain is imparted by applying compressive load to the circumference of the assembled panels. After imparting the compressive strain, the outermost panels 1c are pressed onto a wall 7 and the adhesive 8 is hardened by leaving the panel assembly while applying the compressive load. After hardening of the adhesive, the compressive load is removed. Thus, since uneven strain is absorbed by the mastic material 5 and the adhesive 8, breaking of the panels is not causd by hydraulic pressure. Further, since the compressive force is supported by the adhesive, the panel assembly can be attached even to a weak wall.

Description

[Detailed description of the invention]

Concerning how to construct. We have invented a method for constructing a liquid-tight cold insulation layer that preliminarily gives a cold insulation panel a compressive strain equivalent to the tensile strain that occurs when it comes into contact with a low-temperature liquid. That is, the present invention involves bonding a plurality of cold insulation panels to each other in a two-dimensional manner, attaching the outer periphery of the panel to the wall via the adhesive edge, and attaching the central part of the panel to a Attach to the wall using a surface material with a low coefficient of friction. This method of constructing a liquid-tight cold insulation layer is characterized in that the adhesive is cured by applying compressive force to the entire cold insulation panel from all sides to fix the cold insulation panel to a wall. next. The present invention will be specifically explained based on FIGS. 1 to 4. First, in Figure 3, bolts 4 are mounted on the wall 7 that removes the liquid-tight cold insulation layer.

At this time, the adhesive 8 is applied to the back side of the cold pack IC 17'1, and then the IC 17'1 is attached. The adhesive 8 is used to attach the cold insulation panels Ia, 1b, 1c to the cold insulation panels Ia, 1b, 1c. In Figure 4, the assembly is completed and the cold insulation panel I

It may be tightened lightly within the range to prevent buckling of the pipes, la and lb during compression. By following the steps below, compressive strain is introduced in advance and a liquid-tight cold insulation layer is introduced. The liquid-redundant cold insulation layer Kid constructed using Vcl has the following characteristics: ■The cold insulation panel has weak bending strength like foam glass, and if there is an unevenness between it and the wall, it is easy to Even if 7 is used, the mastic 5 and adhesive (8) absorb unevenness, so it will not break even when hydraulic pressure is applied. ■The compressive force introduced to the cold insulation panel is absorbed by the outermost adhesive part. Since the wall 7 is like a lining plate,
i plate, the joint with bolt 14 is weak, and bolt 1
A liquid-tight cold insulation layer can be constructed even if there is no adhesive 8 by tightening the bolt 14 and nut 13.
Since it is cured in a compressed state, the reliability of the adhesive surface is improved.
