Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powder type heat insulating structure comprising a bag-like shell and powder or piece-like heat insulating material packed inside the bag-like shell.

・For example, it is well known that a large airtight bag is used to send gas at an appropriate temperature and humidity to the inside of a large airtight bag for use in simple low-temperature storage warehouses for agriculture or distribution.

It is easy to construct, dismantle, and transport, and is also easy to seal, making it suitable as a constant temperature room.

However, this method had drawbacks such as partial leakage of indoor gas, changes in air pressure, heat loss, deformation of the bag, and fluctuations in indoor climate conditions when people and cargo entered and exited the bag.

Another method is to create a heat insulating chamber by attaching a large flexible heat insulating board to a double membrane structure inflated with air.

In this case, disadvantages were unavoidable, such as the flexible heat insulating board occupying a huge amount of space during transportation, and the heat insulating board being easily damaged or broken due to bending caused by changing cars.

This invention has a triple membrane structure consisting of a bag-like outer skin of a double membrane structure that encloses air and stands up in a desired shape, and a diaphragm provided between the double membranes. A sealed air chamber and a heat insulating material chamber filled with granular or fragmented heat insulating material are placed adjacent to each other, and both of the compartments are maintained in the desired shape by providing a number of inner walls or frame materials between the diaphragm and the bag-like outer skin. This is a heat insulating structure characterized by the following.

1 and 2 are detailed explanatory diagrams of the present invention, in which FIG. 1 shows a case where the bag-like outer skin is made of a hard plate, and FIG. 2 shows a case where the bag-like outer skin is made of a flexible membrane.

All of them have a double structure that creates the required insulation layer with a small amount of insulation material. This is an example of the figure.

The front side of the bag-shaped outer skin 10 is 1a, and the back side is 1b.

Both sides 1 a Inner wall 2 as a frame material to maintain the slb spacing
There is also a diaphragm 3 that divides the interior into an air chamber A along the outer skin and a heat insulation chamber B.

The inner wall 2 does not necessarily need to be a continuous wall, since the purpose of the inner wall 2 is to connect the outer skins 1a and lb on both sides so that they do not swell due to the internal pressure of the air or the heat insulating material.

It may be used as a frame material of string or sticks, and the front and back sides may be connected intermittently.

Of course, if the inner wall 2 subdivides the inside of the bag-like outer skin 1, damage to one part will not affect the whole.

Considering its purpose, the insulation material naturally has outer skins la and l on both sides.
It is enclosed in the bag-shaped outer skin 1 so as to form a heat insulating layer that is in contact with the entire surface of one or both of the parts b.

The diaphragm 3 of this embodiment is provided on the back side of the outer skin 1B with an average thickness to hold the heat insulating material, but at the same time, it forms a tubular air chamber with internal pressure and functions as a structural material, so that it can be used during storms, etc. This is to increase the internal pressure and prevent it from collapsing.

When air chamber A and insulation chamber B are separated by a diaphragm in this way, a heat insulation layer is created in which a relatively small amount of insulation material is evenly held as described above, and the buckling strength of the structure is increased by a wide cross-sectional area. This can be ensured by the air chamber A.

The heat insulating material may be any material in the form of powder or fragments that can be easily packed into the membrane, and bead-shaped foams, broken heat insulating materials, etc. can be used alone or in combination.

In particular, the latter can be used by pulverizing and fragmenting urethane foam, expanded polystyrene, other porous plastics, films, etc. that are generated as industrial waste, household waste, etc.

For small structures, the insulation can be packed by hand or with a stick.

However, in the case of a large structure, a wind insulating material air filling port 4 is provided at one or several locations at one end of the bag-like outer skin 1, and an outlet port 5 with an air permeable screen that can be opened and closed is provided at the other end (a third
(see figure).

A blower 6 that fills air into the bag-like outer skin 1 is used to fill the air with the heat insulating material.

The work to take out the heat insulating material is easy because it is blown out from the outlet 5 by the wind power of the blower 6.

When blowing only air with the blower 6, it is sufficient to close the communication pipe 7a between the heat insulating material hopper 1 and the blower 6 and switch to blowing air.

If feeding the heat insulating material directly into the suction port of the blower 6 poses a risk of failure, the heat insulating material may be sent to the discharge side of the blower 6 without being sucked in.

□Although it is okay for the insulation material storage part to have a hole that is large enough to prevent the insulation material from leaking out, in order to send the insulation material far away by wind force, it is necessary to keep the middle part airtight and the other end. Outlet 5
It is desirable to allow air to escape only to the

FIG. 4 is an explanatory cross-sectional view of an example of a heat insulating chamber to which the present invention is applied, and the shape of the heat insulating chamber may be hemispherical or semicylindrical.

An example of a building-shaped chamber is shown in FIG. 5, but any other shape of insulation chamber can be created by increasing the internal pressure of the bag-shaped outer shell.

Of course, the entire structure does not have to be an integral shell, but may be constructed by separating it into simple shapes such as floors, walls, ceilings, doors, etc., and combining these parts.

The two embodiments shown in FIGS. 4 and 5 both have the air chamber A and the heat insulating material chamber B shown in FIGS. 1 and 2 separated by a parallel diaphragm 3 to create a heat insulating layer with a minimum amount of heat insulating material.

In this case, the heat insulating layer, that is, the heat insulating chamber B is in contact with the entire surface of the back skin 1b, but it may of course be provided on the front skin 1a side.

In this embodiment, a coating 10 is overlaid on the outer surface of the front skin 1a for the purpose of mainly blocking sunlight and improving weather resistance.

This is, for example, a synthetic fiber sheet using aluminum foil, but if necessary, this may also be powdered to form a heat insulating layer with a °C diaphragm.

During transportation, the bag-like outer skin 1 is folded into a small size and the insulation material is placed in a bag or other container.

Of course, the coating 10 is also folded.

At the construction site, the skin 1 is laid down and spread over the foundation or floorboard 11 under its floor.

The filling port 4 from which the heat insulating material chamber B also came out and the air filling port 4' from which the air chamber A also came out are connected to the blower 6 via the air volume adjusting parts 13, 13 and the switching valve 14.

The blower 6 can send the heat insulating material from the hopper 7 or only air as shown in FIG.

Although the outlet 5 is simply drawn, it has an air permeable screen 9 as shown in Fig. 3, which allows only air to escape.
It can also be fully closed.

. First, when the heat insulating material is sent to the filling port 4 by the blower 6 and the conveying air is released through the screen at the outlet 5, the chamber B is filled with the heat insulating material.

Next, the supply of heat insulating material to the blower 6 is cut off, the valve 14 is switched, and the compressed air is sent to the air filling port 4'X, so that the bag-like outer skin 1 rises into the desired shape.

Lay an insole 12 such as plywood on the internal floor (and make it easy to walk on).

When disassembling, first open the outlet 5 fully and turn on the blower 6 at ℃.
All of the insulation material is blown out from room B by the wind pressure.

For example, if the outlet 5 and the air-permeable storage container are communicated with each other through the bottom, the containers can be changed and stored one after another.

:-Then, by opening the plug (not shown) of the air chamber A and letting the air out, the bag-like outer skin 1 can be folded.

The embodiment shown in FIG. 5 is the same as the embodiment shown in FIG. 4 except that the insulation chamber B is made separately from the floor part B'.

The filling of the floor part B' may be done by separately installing the filling port 4 and the discharging port 5 in one line as shown in Fig. 3, but it is also possible to fill the floor by connecting and communicating with the lower end of the insulation chamber B through a communication port. It's okay.

The above description has been made with reference to a small number of embodiments, but the feature of the present invention is that a bag-like outer shell made of a flexible or rigid material is filled with powder particles or pieces of heat insulating material to form a full heat insulating layer. It is natural that various changes and applications will be made when implementing the design, depending on the designer's known technology.

The materials used can be left up to the designer, but waste insulation materials may contain coarse pieces unless the wind filling method is used.

A flexible outer skin or a strong, airtight sheet such as vinylloy or nylon (trade name) is suitable.

In addition, during strong winds, the internal pressure of the outer skin may be increased and reinforced with ropes, etc.
Although it is necessary to take various precautions with the soil used, such as installing the air pipe below the outer skin and making sure that it has a slope that allows it to pass through the drain sufficiently,
There are no particularly troublesome precautions.

This invention opens the door to using the heat insulating material, which has conventionally always been molded, in the form of fluid particles or fragments.

Since the bag-like outer skin that determines the shape uses a plate or membrane that is easy to shape, a freely shaped insulation member or insulation structure can be made, and filling with insulation material is quick and easy.

In the case of large structures such as temporary warehouses, the benefits of being able to fold the bag-like outer skin, storing and transporting the insulation material in bags, cans, etc., and being able to easily construct and dismantle nests using a blower are Extremely thick.

The insulation material used paves the way for the reuse of waste such as plastics, and is easy to handle as it is in the form of powder or fragments.
When removed from the outer shell, it can be dried and used for other structures, allowing its fluidity to be utilized.

If an airtight membrane is used as the outer skin, the insulation effect of both air and insulation material can be obtained, making it possible to create a huge insulated room that is lightweight, inexpensive, easy to repair, and has no pillars.

If the inside of the outer skin is subdivided by the inner wall, there is no risk of collapse even if some air leaks.

There is no need to constantly operate the blower like in the conventional case.

The present invention, which achieves the above-mentioned effects by fluidizing the heat insulating material, provides designers of heat insulating members and structures with new perspectives and means.
