Description

The present invention provides a thermal insulation lining for the walls of a structure defining a building space, for example, the inner wall of a building, or the furnace wall of a high temperature furnace such as an electric furnace or various combustion furnaces. The initial lining process for forming the initial lining layer by holding the ceramic fiber insulation layer with the metal studs to be installed, and the finish lining layer is formed on the surface of the initial lining layer on the premises space side And a finishing lining process.
Furthermore, this invention relates to the heat insulation layer laminated block pack used for this heat insulation lining method.

  As such a heat insulation lining method, for example, a plurality of metal studs planted on a furnace wall in a high-temperature furnace are sequentially stacked by stacking ceramic fiber blankets until a predetermined thickness is reached. An indefinite refractory material (called so-called “castable”) was prepared in-situ on the initial lining layer around the V-shaped portion of the stud tip exposed from the initial lining layer. There is one in which a finished lining layer is formed by pouring into a mold and curing. (For example, refer to Patent Document 1.)

  In addition, an initial lining layer is formed with a number of ceramic fiber thermal insulation blocks supported by studs planted on the furnace wall, and an indeterminate refractory material is sprayed on the surface of the initial lining layer consisting of these thermal insulation blocks. Then, there is one that forms a finished lining layer by curing and curing. (For example, see Patent Document 2.)

  As a heat insulating block made of ceramic fiber, for example, as shown in FIG. 10 of Patent Document 3, a plurality of flat heat insulating fiber layers obtained by cutting a blanket made of ceramic fiber into a predetermined size and a CD case placed vertically are arranged horizontally. A pair of skewer rods 26 that are arranged side by side in the horizontal direction so that their large planes are directed sideways, and skewer a plurality of flat heat insulating fiber layers arranged horizontally, and the pair of skewers A metal fitting 50 for connecting the rods to each other and a parallelepiped block having a predetermined dimension are formed, and the stud is connected to the center hole of the metal fitting 50.

  In addition, as necessary, the periphery of the juxtaposed body arranged side by side is bound in the horizontal circumferential direction with a pair of bands, or the flat heat insulating fiber layers juxtaposed side by side are bonded and fixed or glued with an adhesive. there were. In the case of a block in which juxtaposed bodies are bound, bonded, or stitched in this way, it was in a bare state (even if it was a band bundle, except for the band tied portion), so the ceramic fiber dust during transportation, loading and lining operations Scatters and workers need careful protective measures to protect their eyes and respiratory organs. Moreover, the band which binds the heat insulation block was removed after the block installation was performed.

  Furthermore, in the conventional heat insulation block, the studs to be planted on the furnace wall are arranged so that the center hole for inserting the metal studs is located on the narrow plane side of the flat heat insulation fiber layer so that the studs can be easily inserted into the block. Since the studs are inserted in parallel to the boundary surface (interface) of the adjacent flat insulating fiber layer, the heat insulating block itself cracks in parallel to the boundary surface (interface) and easily falls off the stud. The applicant has found that there is a point.

  The object of the present invention is to save the trouble on site, as in the prior art, and to perform the initial and finishing lining operations in a short time, easily and reliably, and can be manufactured easily and at low cost. An object of the present invention is to obtain a heat insulating lining method and a heat insulating layer laminated block pack used for this lining method, which can perform the initial lining operation using a heat insulating block that avoids problems and has a low risk of falling off from a stud.

In order to achieve this object, in the heat insulating lining method of the present invention, the initial lining step is to form a laminated body having a predetermined height by sequentially leveling at least the main plane of the flat heat insulating fiber layer, and flat heat insulating at the sharp end of the guide pin. After inserting the guide pin through the laminated body by piercing the plane center of the fiber layer, and embedding an insert having a tapered guide on the proximal end side of the guide pin to be penetrated in the flat heat insulating fiber layer on the proximal end side, Pull out the guide pin and use a heat insulating layer laminated block pack in which the entire periphery of the laminate having at least a plurality of flat heat insulating fiber layers is hermetically sealed with a film, and the stud is attached to the base surface of the heat insulating layer laminated block pack on the base end side. Align the taper guide's widened end of the exposed insert with the film of the heat insulation layer laminated block pack. The heat insulating layer laminated block pack is inserted into the heat insulating layer laminated block pack, a retainer washer is attached to the end of the stud exposed from the surface of the heat insulating layer laminated block pack on the premises space side, and the heat insulating layer laminated block pack is attached to the inner wall or the furnace wall. Fixed,
The finishing lining step is characterized in that a finishing heat insulating material is disposed in close contact with a surface layer of the heat insulating layer laminated block laid along an inner wall or a furnace wall.

  According to the present invention, a flat heat insulating fiber layer obtained by cutting a blanket made of ceramic fiber into a predetermined size is not arranged as if the CD cases are juxtaposed in the horizontal direction, but the main plane of the flat heat insulating fiber layer is made horizontal. The center of the main plane is pierced at the sharp end of the guide pin so that the guide pin penetrates the laminate of the flat heat insulating fiber layer, and the guide pin is tapered toward the base end side of the guide pin to be penetrated. After inserting an insert having a flat insulating fiber layer on the base end side, a guide pin is pulled out and a laminated block pack in which at least a plurality of flat insulating fiber layers are hermetically sealed with a film is used. Therefore, there is no need to insert a skewer pin or metal fitting in the block like the conventional heat insulation fiber block, Since only the insert is present having a tapered guide flattened heat insulating fiber layer, configuration can be easily and inexpensively manufactured.

  Furthermore, the entire periphery of the laminate having a flat heat insulating fiber layer is hermetically sealed with a film, and since the hermetic pack does not need to be removed after the block is installed, fiber dust can be reliably prevented from being scattered. Will not harm your health.

  In addition, the heat insulating layer laminated block pack is fixed to the stud by aligning the stud with the expanded end portion of the taper guide of the insert that is exposed on the base plane (bottom surface) of the heat insulating layer laminated block pack. When the film is punctured and the heat insulation layer laminated block pack is pushed toward the inner wall or the furnace wall, there is a trace of the insertion hole of the guide pin formed in advance when laminating the flat heat insulation fiber layer, so it is pushed in without difficulty. This can greatly reduce the burden on workers.

  After the retainer washer is fixed, all the flat insulated fiber layers are skewed in a direction perpendicular to the layer boundary surface of the laminate, so that the insulation layer laminate block pack is less likely to fall off the stud than before. Become.

  Furthermore, since there is a trace of a guide pin insertion hole that is formed in advance when laminating the flat heat insulating fiber layer, the tip of the stud does not need to be so sharp, so that the worker can The risk of injury is reduced.
