Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a prefabricated heat insulating structure using load-bearing wall heat insulating panels and a method for constructing the same. especially,
This invention relates to prefabricated insulating structures such as freezers, refrigerators, heating cabinets, etc., prefabricated housing for extremely hot or extremely cold regions, temporary construction sites, and residences, and their construction methods.

(Prior Art) Conventionally, heat insulating structures such as prefabricated freezers have been constructed using load-bearing heat insulating panels for walls and ceilings or flat roofs and floors. The conventional heat insulating panel and heat insulating structure will be explained.

Conventional wall insulation panels consist of a pair of inner and outer surface plates arranged opposite to each other, a joint frame that surrounds the space narrowed between the inner and outer surface plates, and a load-bearing foam that is injected into the surrounding space by high-pressure injection foaming. It basically consists of a heat insulating layer. Both the inner and outer surface plates are anodized aluminum plate, colored aluminum plate, colored steel plate, vinyl chloride coated steel plate, stainless steel plate, F
A surface material such as an RP board is used, and the surface shape can be corrugated or keystone deck-like, but generally it is flat.

Further, the wall insulation panel has an outer surface, an inner surface, a top surface, a bottom surface, and both side surfaces. Insulating panels for walls, flat roofs, and floors, which are common basic modules, are composed of joint frames made of synthetic resin such as vinyl chloride with high heat insulation properties on the top, bottom, and both sides. Furthermore, the wall insulation panel to which the floor insulation panel is connected was comprised of a joint frame on the top surface, both side surfaces, and the bottom end of the inner surface board. In this case, the wall insulation panels were also used for flat roof insulation and ζ panels.

Next, the insulated structure assembled using the above-mentioned insulating panels for walls and flat roofs or insulating panels for floors is constructed using a reinforced concrete foundation built underground and a base made of C-shaped steel or the like fixed to the foundation with anchor bolts. , a wall insulation panel that is erected and connected to the foundation with anchor bolts, etc., a flat roof insulation panel that is erected and connected between the tops of the erected wall insulation panel, and an erected wall insulation panel. It basically consisted of an insulating floor concrete or floor insulating panels poured or laid between the lower parts of the panels.

Insulated structures constructed using the above-mentioned wall insulating panels, especially when installing floor insulating panels, lay the floor insulating panels through a heat insulating layer using wood panels placed on a base concrete. However, the cold heat generated ice on the wooden panels, pushing up the floor insulation panels due to frost heaving and causing the floor level to become shaky.

In addition, when pouring concrete for the floor, because the wall insulation panels are not firmly fixed vertically on the base of C-shaped steel, etc., after the wall insulation panels are set and fixed upright, a flat roof is placed between the wall insulation panels. The first step was to erect and connect the heat insulating panels, then install a heat insulating layer of foamed polystyrene or the like on the base concrete, and then pour floor concrete on top of that to build the insulated floor. For this reason, insulation panels for flat roofs could only be erected from the outside, and even if they could be built from the inside, it would only be an auxiliary work after the concrete floor had hardened. This was particularly disadvantageous in the case of large-area structures.

Additionally, there was no space in the wall insulation panels to provide ventilation holes to release the cold and heat accumulated in the insulation layer, such as the wooden panels on the insulation floor.

(Object of the present invention) A base 25 that allows a wall insulation panel 1 to be more firmly erected on a base 25 fixed on a foundation 24, and a wall that can be erected and fixed to the base 25 more firmly than before. insulation panel 1,
Insulated floor 1 with floor concrete 21 poured using
Prefabricated heat insulating structures A, A', B, Ilr that can use the heat insulating floor 16 constructed with the heat insulating panels 21 for flat roofs or ceilings for construction work of heat insulating panels for flat roofs or ceilings, and methods for constructing the same. The purpose is to obtain The present invention also relates to prefabricated heat insulating structures A, A, B, and g that allow ventilation of the heat insulating layer 22 of the heat insulating floor, if necessary, and a method for constructing the same.

(Means for achieving the purpose) The horizontal lower surface 5 integrally connected to the outer surface plate 3 of the wall insulation panels 1 and 2, and the entire or most part of the vertical inner surface plate 4 integrally connected to the lower surface 5. In addition to using wall insulation panels 1 and 2 integrally formed with a U-shaped cross-section,
The above object is achieved by using a C-shaped steel section for the base 25 that is fixed on the foundation 24 with the opening facing upward, and by standing and fixing the wall insulation panel 1 on the base 25.

(Example) The heat insulating structures A, A', B, and B' of the present invention and their construction method will be explained.

However, before that, the heat insulating structure A of the present invention.

We will explain the new wall insulation/ζ-nel 1゜2 used for λ, B, and ``.

The wall insulation panels 1 and 2 are classified into two types. (Refer to Figure ÷) Type 1 Wall Insulation Panel In the Type 1 Wall Insulation Panel 1, the outer surface board 3 and the inner surface board 4 are integrated with both surface boards 3, 4 and the lower surface 5 of the same material. At the same time, a joint frame 9 made of vinyl chloride or the like with high heat insulation properties is provided on the top surface 6 and both side surfaces 7 and 8 of the wall insulation panel 1. That is, the lower surface 5 of the wall insulation panel 1 is directly 1. It is installed vertically in the opening of the C-shaped steel used for the base 25 to transmit the vertical load acting on the panel directly to the base 25, and the fixation between the base 25 and the wall insulation panel 1 is made using the C-shaped steel rain vertical wall. This can be done by passing bolts and nuts 27 through the wall, and the wall insulation panel 1 can be fixed to the base 25 more firmly than before. Of course, if necessary, a ventilation hole can be provided at a certain height above the bottom surface 5 of the wall insulation panel 1 (thickness of the insulation layer 22 made of a wooden panel or insulation material), or on the outside surface 3 side. It is also possible to provide a fireproof layer 12 inside.

In the panel type 2 wall insulation panel 2, the outer surface board 3 and the inner surface board 4 are connected via the lower surface 5, similar to the type 1 wall insulation panel 1. However, the outer surface board 3 is also integrally connected to the upper surface 6, and the top end side of both sides 7, 8 of the wall insulation panel 20 and the inner surface board 4 are made of a seam made of highly insulating polyvinyl chloride or the like. A frame body 9 is provided. The relationship between the pipe insulation panel 2 and the base 25 of type 2, and the installation of the ventilation opening 15 and the fireproof layer 12 are the same as in type 1.

As mentioned above, the common point between types 1 and 2 of wall insulation panels 1 and 2 is that at least all or most of the outer surface plate 3, lower surface 5, and inner surface plate 4 are The parts are integrally formed and connected, and the lower part of the inner and outer surface plates 3 and 4 having a U-shaped cross section has a space in which a ventilation opening 15 can be provided.

Furthermore, the common point is that, like the heat insulating panels incorporating structural members in the applicant's previous application, the structural members 14 can be built into the wall panels 1 and 2, and the structural members 14 can also be built in for flat roofs or ceilings. The panel 20 can also have a built-in structural material 14, and in some cases, the floor heat insulating panel 21 also has a structural material 14 (made of a structural material such as steel or square steel coated with a heat insulating coating). It has a built-in floor insulation panel 2IC that is strong and has a good load capacity.

In addition, the wall insulation panel 1゜2 containing the structural material 14 is
Similarly, when connecting flat roofs or ceiling or floor insulation panels 20C and 21C that have structural members 14 built-in, or when having a joint frame 9, the structural material is attached to the connection point or the joint frame 9. It is also possible to arrange connection plates etc. provided with 14.

Next, structures A', B, and g constructed using the wall heat insulating panels of types 1 and 2 will be roughly divided into types A and B and explained.

Next, a base 25 made of C-shaped steel or the like is fixed onto the foundation 24 via anchor bolts 27 which are provided in advance to protrude from the foundation 24 so that the opening faces upward. Next, pace conc IJ-) 23 is poured between the foundations. Then type 1

The wall insulation panel 1 is fixed to the base 25. When all the wall insulation panels 1, entrance doors, etc. 35 have been erected and fixed, the wall of the insulation structure A to be constructed is constructed. Then, a load-bearing heat insulating board made of styrene foam or the like is laid on the pace conc IJ-) 23, and the heat insulating layer 22

Next, floor concrete 21 is placed on top of the heat insulating layer 22 to construct the heat insulating floor 16.

In this case, it is more preferable for the floor concrete IJ-) 21 to be made of a material such as lightweight cellular concrete with cold insulation properties in terms of insulation. Next, the flat roof insulation panel 20 is constructed on the wall using the already constructed insulation floor 16 as a working floor,

The bolts 27 are passed horizontally through the bolt insertion holes of the structural wall panel IC that communicate with the holes and the port insertion holes previously provided in the structural material 14, and the insulation panel 1 for the wall or the structural wall is inserted as necessary. The panel IC is fixed to the base 25. When all the structural wall panels IC, the normal wall heat insulating panel 1, the entrance door 35, etc. have been erected and fixed, the structural wall of the roofed heat insulating structure X to be constructed is constructed. Then, a heat insulating board made of styrene foam or the like having load-bearing properties is laid on the base concrete 23 to provide the heat insulating layer 22. Here, when the structural wall panel IC has a ventilation opening 15, a cold air circulation groove or hole for letting cold air escape to the ventilation opening 15 is provided in advance on the upper surface or lower surface of the heat insulating layer 22, or inside the insulation layer 22. Next, floor concrete 21 is placed on top of the heat insulating layer 22 to construct the heat insulating floor 16. Next, the ceiling insulation panel 20 (in this case, since it does not form a flat roof, it is deliberately called a ceiling insulation panel) is installed and fitted onto the structural wall using the already constructed insulation floor 16 as a working floor. Here, the joint between the ceiling insulation panel 20 and the structural wall transmits the load and tensile force transmitted from the head joint 28 made of C-shaped steel or the like placed on the ceiling insulation panel 20 to the structural wall. It is structured in such a way that it can be done.

Further, the ceiling heat insulating panel 20 can also have a built-in structural material in the same way as the structural wall 1, in which case the following trusses and head connections are not required and the roof is not constructed.

Next, the head tether 28 is placed on the top of the structural wall on the ceiling heat insulating panel 20, and the head tether 28 and the structural wall are connected and fixed using bolts, nuts, plates, etc. Next, between the head joints 28, an I-shaped beam 29C, an I-shaped truss 29d, a chevron-shaped truss 29a, and a single-side flow truss 29b are installed.
A roof frame such as the above is erected, and the head tether 28 and truss 29 are fixed. Next, the roof 3 is placed on the roof assembly such as the truss 29.
0 is installed. Further, if necessary, when the span of the ceiling heat insulating panel 20 is too short, the ceiling heat insulating panel 20 is suspended and supported from a roof frame or the like via hanging bolts 34 to prevent deflection.

A foundation 24 is constructed at the location where the heat insulating structure B is planned to be constructed, a foundation 25 is fixed on the foundation 24, and base concrete 23 is placed between the foundations 24. Then, the type 2 wall heat insulating panel 2 is erected and fixed on the base 25, and the wall body is constructed. Next, a heat insulating board is laid on the base concrete 23 to provide a heat insulating layer 22, and a floor concrete IJ-) 21 is placed on the heat insulating layer 22 to construct the heat insulating floor 16. Next, the heat insulating panel 20 for a flat roof is fitted and installed between the inner parts of the walls using the heat insulating floor 16 as a working floor, and the heat insulating structure B is constructed.

In addition, a heat insulating structure with a roof can be constructed using structural wall panels 2C.
If you are building a foundation 24. Foundation 25. The base concrete 23 is constructed in the above steps, and then the foundation 2
A structural wall panel 2C is erected and fixed within the opening 5. When all the structural wall panels 2C, the entrance door 35, and the normal wall insulation panels 2 inserted as necessary are erected and fixed, the structural walls of the roofed insulation structure to be constructed are constructed. Then, a heat insulating layer 22 is laid on the pace conc IJ-) 23, and a floor conc I
J-) 21 is poured to construct the insulating floor 16. Next, the ceiling heat insulating panel 20 is fitted and constructed between the structural walls, using the heat insulating floor 16 as a work floor. Here, the ceiling heat insulation panel 20 is the structural material 1 like the structural wall panel 2C.
4 (in other words, the roofless type),
The structural material 14 inside the structural wall panel and the structural material 14 built into the ceiling insulation panel 20 are susceptible to shearing force, bending moment,
They must be connected so that axial force, etc. can be transmitted.

Next, the head joints 28 are fixed on the structural walls of the heat-insulating structure with a roof, a roof frame such as a truss 29 is erected and fixed between the head joints 28, and a roof 30 is installed on the roof frame.

As mentioned above, the common point between types A and B insulation structures is that in wall insulation panels 1 and 2 and structural wall panels IC and 2C, at least all or Most of the parts are integrally formed and connected, and there is a ventilation hole at the bottom of the inner and outer surface plate parts that have a U-shaped cross section.
5 has space that can be provided.

Furthermore, the flat roof insulation panels 20 of Types 1 and 2 insulation structures A and B can incorporate the structural material 14, and by combining with the wall insulation panels IC and 2C with built-in structural materials, a structure without a roof can be created. J, B/ for insulating structures with built-in materials
/ can be constructed.

(1'1, all panels have built-in structural materials) In addition, instead of the floor concrete 21 of types 1 and 2, the floor insulation panels 21C with built-in structural materials are used, and the structural wall panels IC, 2C and Insulation panel 20C for flat roofs with built-in structural material
By combining these, it is possible to obtain a roofless heat-insulating structure AI'/, gll with a built-in structural material and a high floor strength.

In this case, it is a wall insulation panel IC with built-in structural material.

In 2C, a connection plate of the structural material 14 is arranged at the connecting joint frame body 9 and at the connection point of the flat roof and floor insulation panels 20C and 2IC containing the structural material to be connected.

In addition, prefabricated insulation structures (A, A', λ/, A''
l, B.

ff, B'', B''''') does not necessarily construct a wall only with wall insulation panels 1 and 2 of types 1 to 2, but can also appropriately combine conventional insulation panels as necessary. Needless to say.In particular, it is preferable to use types 1 and 2 wall insulation panels 1 and 2 for wall insulation panels with built-in structural materials.Anyway, type 1,
If the two wall heat insulating panels 1 and 2 are used as part of a wall, one form of the prefabricated heat insulating structure of the present invention is formed.

Furthermore, when using a wall insulation panel with a fire-resistant layer, it is essential that the joints between the panels have fire-resistant specifications, such as fitting the fire-resistant tongue pieces 43 or removing the outer surface plate at the joints that contact the fire-resistant layer. This is achieved by mating the male and female parts or filling the joint with a heat-resistant adhesive or filler.

Additionally, this fire resistance specification applies not only to walls, but also to ceiling and floor joints. Furthermore, the seam also serves to prevent flammable gas from blowing out.

(Effects) 1. The wall that supports the load applied or acting on the flat roof or ceiling is reliably and firmly connected to the foundation.

2. If necessary, ventilation holes can be provided in the wall insulation panels and structural wall panels to prevent frost heave on the insulation floor.

3. By using walls, flat roofs, and floor panels with built-in structural materials, it is possible to construct insulating structures with a relatively flat surface and large area at low cost.

4. Small-area insulation structures can be assembled quickly, safely, and accurately compared to conventional assembly methods.

5. The constructed floor can be used as a work floor.
