Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of Application The present invention relates to a heat insulating structure using heat insulating panels as a wall panel that also serves as a pillar and a ceiling panel that serves as a beam.
In particular, the present invention relates to insulating structures such as storage units such as freezers, refrigerators, or heating cabinets, residences in extremely hot or extremely cold regions, temporary offices and residences for construction sites, and methods for constructing the same.

(b) Conventional technology The above-mentioned insulating structures using insulating panels are not subject to the Building Standards Law if their floor area is less than ^10m2 , so simple prefabricated insulating structures can be used regardless of whether they are indoors or outdoors. Many structures have been placed.
(Utility Model Publication No. 56-003389, Publication of Utility Model Publication No. 58-024143, Publication of Utility Model Publication No. 53-034594) On the other hand, if the floor area exceeds 10 m ² , the above-mentioned heat-insulating structure will inevitably fall under the Building Standards Act. Since the various stresses such as Young's modulus E, moment of inertia I, etc. of the insulation panel have not been clarified even in official tests, the insulation panel itself is used as a part of the structure (framework). I couldn't do that.

Therefore, in order to construct an insulated structure with a floor area of 10m2 ^or more, it is necessary to first construct a skeleton structure (framework) using steel frames or reinforced concrete, and then additionally attach insulation panels to the outside or inside surface. or set up
The above-mentioned heat-insulating structure was completed by applying a heat-insulating material. (Japanese Utility Model Publication No. 53-108718, Publication of Utility Model Application No. 55-48098, Special Publication No. 52-012939)
However, constructing a frame structure (framework) is expensive, and in order to complete the insulation structure, it is necessary to separately lay or attach insulation panels. It was more expensive, required more construction steps, took longer, and required construction engineers of a certain level or higher.

In addition, when constructing temporary insulated houses or offices on construction sites, as well as houses for extremely hot or extremely cold regions, it is extremely important to minimize on-site construction as much as possible. There has never been a heat insulating structure with a simple configuration, good precision, and a method for constructing the same that can be easily constructed.

(c) Purpose of the invention Therefore, there is a need for a storage facility that requires less construction work, is simple, has sufficient insulation performance, is inexpensive, and has high precision at sites where construction conditions are poor, such as in extremely cold or extremely hot regions. The purpose of this study is to learn about insulating structures such as drying warehouses and residences, and how to construct them.

(d) Technical means to achieve the purpose Structural insulation panels containing structural materials with clear stresses required for the structure are manufactured in advance at a factory, and then placed on the foundation poured on site. Build the auxiliary corner pillars and the main structural wall on the installed foundation, then construct the insulated ceiling using structural insulation panels on top of the structural wall, and install the ceiling using auxiliary beams and girders. The above objective is achieved by enclosing the four sides and covering the roof with a roofing sheet if necessary.

(e) Examples A heat insulating structure and a method for constructing the same, which are examples of the present invention, will be described with reference to FIGS. 1 to 7.

Before that, the specific configurations of the pillar-cum-insulating wall panel 2 and the beam-cum-insulating ceiling panel 3 used in the heat-insulating structure 1 and its construction method of the present invention will be explained with reference to FIG. 3.

The insulating wall panel 2 serving as a column and the insulating ceiling panel 3 serving as a beam include inner and outer panels 4 and 5 made of aluminum plates, colored steel plates, plastic plates, etc., and the inner and outer panels 4 and 5 described above.
A joint frame 7 made of vinyl chloride or the like having high heat insulation properties surrounding a space 6 between them, and a pair of structural members arranged in the longitudinal axis direction of the panels 2 and 3 near the center of the space 6. 8, and a heat insulating material 9 injected and foamed into the remaining portion of the space 6.

In the thickness direction of the heat insulating panels 2 and 3, the structural material 8 is located at the center, on the inner panel 4 side, and on the outer panel 5 side.
Although it may be placed on either side, in order to maintain the insulation performance of the insulation panels 2 and 3 and to prevent an increase in the amount of heat stored, it is preferable to place it at least in the center or on the outer panel 5 side. In this case, it is particularly preferable to arrange it in contact with the outer panel 5 in order to support loads such as snow loads.

Furthermore, the material of the structural member 8 is preferably wood with good heat insulation properties, or a steel frame such as lightweight section steel coated with heat insulation coating or heat insulation coating. Further, polyester resin such as FRP, reinforced carbon fiber, stainless steel, etc. can also be considered.

Further, the foamed resin heat insulating material 9 may include urethane,
Phenol, styrene, etc. are preferred.

The heat insulating structure of the present invention and its construction method will be explained step by step.

A foundation concrete 10 is placed at a location where the heat insulating structure 1 of the present invention is planned to be installed.

Next, a base 11 such as a shaped steel is fixed onto the foundation concrete 10 using anchor bolts 12 buried in the foundation concrete 10.

A structural wall 14 of a desired shape and height is created by fixing the pillar-cum-insulating wall panels 2 to the base 11 with bolts and combining them with conventional heat-insulating panels 13 as needed.
Build.

Here, when using the heat insulating structure 1 of the present invention in a residence, an office, etc., it is necessary to use the conventional heat insulating wall panels 13 and structural members 8, which are not expected to have structural strength. The structural heat insulating panels 2 and 3 used in the present invention having a space include the conventional 2
Insulated windows, insulated doors, heat exchange type ventilation equipment, etc. made of heavy glass can be installed in advance at the factory, or installation frames can be prepared in advance so that insulated windows can be installed on-site. The processed heat insulation panels 2, 3, and 13 may be assembled at desired locations as appropriate.

In addition, the insulating wall panel 2 that also serves as a pillar is a general term that also includes the corner insulating wall panel 15 that also serves as a corner post.
The corner insulating wall panel 15 which also serves as a corner pillar has the same basic structure as the insulating wall panel 2 which also serves as a pillar, and is simply the inner panel 4 and the outer panel 5 bent at right angles.

Next, auxiliary columns 1 are installed at the four corners of the structural wall 14.
6 is welded or bolted to the base 11 and erected,
If necessary, the corner insulation panels 15 that also serve as corner pillars of the structural wall 14 and the auxiliary pillars 16 are fixed with bolts or the like to promote integration.

Next, a structural ceiling body 17 is constructed by piecing together the beam insulation ceiling panels 3 on the structural wall body 14 to form a bottomless box-shaped insulation panel structure 18.

Next, the auxiliary beams 19 and the auxiliary girders 20 are arranged around the structural ceiling body 17, and the auxiliary columns 16
At the same time, the structural member 8 built into each beam-cum-insulating ceiling panel 3 and the auxiliary beam 19 and the auxiliary girder 20 are integrally fixed with bolts or the like.

In this case, depending on the length of the ceiling span, conventional methods (1983-
34594), by extending one or more ceiling reinforcing beams 21 between walls, bottomless box-shaped insulation panel structures 18 having various floor areas as shown in FIG. 7 can be constructed. . In addition, if necessary, auxiliary columns 22 may be installed inside the bottomless box-shaped insulation panel structure 18.
If it is erected, it is possible to construct a heat insulating panel structure 18 that can accommodate a considerable span.

In the case of a freezer, it is preferable to arrange the ceiling reinforcing beam 21 as far outside the structural ceiling body 17 as possible in order to prevent frost buildup. Furthermore, when using the heat insulating structure of the present invention in a residence or an office, it is better to locate the ceiling reinforcing beam 21 inside as much as possible to improve the appearance, make it easier to waterproof the roof, and make it suitable for internal partitions. can also be used.

Next, a wall reinforcement 23 and a ceiling reinforcement 24 are applied.

Next, a roof sheet member is applied to the upper part of the ceiling body 17 using a pressure-sensitive adhesive or a coating adhesive to make the ceiling body 17 waterproof, if necessary.

In this case, the heat insulating panels 2 and 3 of the present invention are waterproof, and the joints between the heat insulating panels 2 and 3 are also waterproof, so the roof sealing member is not necessarily required for the heat insulating structure 1 of the present invention. However, it is never a good idea to install a roof sheet material in consideration of long-term waterproof safety.

Next, a heat insulating floor body 25 is laid at the bottom of the bottomless box-shaped heat insulating panel structure 18.

In this case, the heat insulating floor body 25 is constructed by placing a floor concrete 27 on the foundation concrete 10 via a heat insulating material 26, or
It is constructed by laying a floor insulation panel directly on top of the floor.

In the heat insulating structure 1 of the present invention, in order to maintain its heat insulation properties and provide sufficient structural strength to the heat insulating wall panel 2 that also serves as a column, the thickness of the heat insulating wall panel 2 that also serves as a column and the heat insulating wall panel 13 is set at least. The heat insulating wall panel 2 that also serves as a column is made thicker, and the joints between both panels 2 and 13 are connected via a modified joint.

However, if inefficiency and high cost are not a concern, the thickness of both panels 2 and 13 can be made the same to prevent the occurrence of irregularly shaped seams.

(f) Effects of the invention (i) Various types of insulation structures can be constructed based on conventional structural calculations, regardless of the size of the floor area, without constructing a separate frame.

(ii) Since a separate expensive frame is not required, a desired insulation structure can be constructed at low cost and in a short period of time.

(iii) Except for the foundation concrete and insulated flooring, pre-fabricated insulating panels can be used;
There is less on-site construction, the construction accuracy is good, and the construction period can be shortened.

(iv) Insulated windows and doors are pre-installed in the factory with insulated wall panels 1
3, or if a mounting frame is prepared in advance at the factory so that insulating windows etc. can be installed on-site, the insulating structure of the present invention can be used for residences in extremely hot or extremely cold regions, residences for construction sites, and offices. It can be easily converted to a drying room, etc.

(v) A certain level of construction accuracy can be maintained without requiring specially trained construction engineers.
