Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial field of use The present invention fills a heat insulating material between both inner and outer plates arranged at a predetermined interval, and arranges a frame material on the periphery thereof. Insulation panels.

2. Description of the Related Art In order to construct a prefabricated refrigerator or a refrigerator, a plurality of heat-insulating panels are usually combined to form a box having a top wall, a side wall, and a bottom wall. In this combination, JP-A-62-91779 is used. As disclosed in the publication, for example, a concave portion and a convex portion are formed at an end portion of a heat insulation panel having a size of one tatami mat, and the convex portion is fitted into the concave portion, so that the concave portion and the convex portion are combined. Panels are connected to each other by a connecting device called a rotary type lock.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As the prefabricated refrigerator in the above publication, there is no particular problem as long as the place where it is arranged has a substantially flat wall surface, but when the wall surface has a convex portion such as a pillar, it remains as it is. Correspondence is difficult. Therefore, it is necessary to form an escape recess for escaping the convex portion. Before forming the relief recess, at least one of the panels forming a part of the ceiling wall is provided with a notch that corresponds to the shape of the protrusion, and the cutout is formed. A panel for the side wall as well as a panel for the bottom wall must be shaped to fit the size of the notch. However, when connecting the panels to form these escape recesses, it is not possible to use the conventional recesses and protrusions and rotary locks, but use a different connecting member with a flat end surface. Therefore, there is a problem that the workability is poor and the panel cannot be connected in a strong state due to the notch work and the use of other connecting members.

Therefore, the present invention provides a heat insulating panel that has a notch corresponding to a column escape recess as a box body and that can be connected and connected by a rotary lock to a panel that is vertically connected to the panel surface.

[Structure of Invention]

Means for Solving the Problems The heat insulating panel provided with the notch portion of the present invention is formed in a notch at positions corresponding to the escape recesses, which are arranged substantially symmetrically with a predetermined distance from each other and remove the notch. An inner and outer surface member having a flange portion at its end portion and a flange portion corresponding to an orthogonal connection portion with another panel are formed, and an engaging portion for engaging the flange of the inner surface member is formed at the end portion and is recessed. A groove is formed to form one surface having the same surface position as that of the inner surface material, and a receiving portion, which is formed flat and receives the flange portion of the outer surface material, and two surfaces adjacent to each other at a right angle from the other surface formed at the end thereof. A first frame member in which a rotary lock is arranged inward of the concave groove, and an insertion portion having a groove for inserting the notched end of the inner surface member is formed at the end portion thereof and the concave surface is formed. A locking portion having a groove shallower than the insertion groove for locking the notched end of the outer surface material is formed at the end. A second frame member having two surfaces that are adjacent to each other at a right angle from the other surface that is formed into a flat shape and in which the rotary lock is disposed inside the concave groove,
It is composed of a foamed heat insulating material filled between the inner and outer surface materials, and is arranged at a part of the escape recess.

Action An engaging portion is formed at one surface end of the first frame member so that the flange portion of the inner surface member can be directly engaged with the engaging portion. Further, a receiving portion is formed on the other surface end portion of the first frame member so that the flange portion of the outer surface material is received as it is, and after the flange portion of the inner surface material is engaged, the flange portion of the outer surface material is removed. It can be easily attached to the first frame member.

Furthermore, an insertion portion having a groove is formed at one end of one surface of the second frame member so that the insertion of the inner surface member in a flat state can be performed without end treatment of the notch, and The one side and the one side have the same surface position. Further, a locking portion having a groove shallower than the insertion portion is formed at the other surface end portion of the second frame member, and the tip end of the notch of the outer surface material is inserted into the locking portion to be easily locked. The notched portion of each face member is inserted or locked in the frame member as it is to facilitate the connection work between each face member and the second frame member.

However, when connecting and connecting the panels to each other, the connecting portion is the portion of the frame material, and this frame material is divided into one having a concave portion and one having a convex portion, and the convex portion is combined with the concave portion to be integrated. At this time, a coupling device called a rotary lock (this rotary lock is a pair of a hook body having a hook and a pin body having a pin) (25). Firmly connect and fix panels together. As the rotary lock (25), for example, a hook member is provided inside a frame member having a convex portion (this is referred to as a fourth frame member (9)), and a frame member having a concave portion (this is referred to as a third frame member).
The frame body (8) is arranged inside, and the two pins are firmly locked by rotating the hook of the hook body to the pin of the pin body and hooking it to a fixed position. Therefore, a third frame member having concave portions on each of four surfaces in the plate thickness direction of the panel is provided.
(8) One of the fourth frame members (9) having a convex portion is arranged. It should be noted that this corresponds to a panel that does not participate in the formation of a relief recess described later.

On the other hand, if there is no convexity due to the presence of pillars or the like in the place where the assembly-type cold storage (1) is installed, there is no particular problem because the entire low-temperature storage (1) may be a flat box body, If there is a pillar etc. in the place (inside the building) where it is installed and there is a protrusion, it is common to form an escape recess to escape this protrusion and use the installation space efficiently. The structure for forming the escape recess (10) will be described below.

When forming this escape recess (10), the side wall panel (3)
Since it is sufficient to form the width corresponding to each side of the recess, the recess

Form notches having shapes suitable for (6). Here, a detailed description will be given taking the U-shaped ceiling panel (12) in FIG. 2 as an example.
Each face member (5) (6) has a notch (13) at a corresponding position so that it has a U-shape in plan view, and a flange having a substantially L-shape in cross section at the end side excluding the notch portion. Form part (14).

In the flange portion (14) of the inner face plate (5) in this state, the first frame member (15) is attached to a portion (which is referred to as an orthogonal connecting portion) that needs to be connected and connected orthogonally to the side wall panel (3). ) Is attached. The first frame member (15) has two surfaces which are adjacent to each other at a right angle, one surface of which is substantially the same surface as the inner surface material (5) and the other surface is an end surface of the panel. A concave groove (16) corresponding to the convex portion of the fourth frame member (9) of the panel (3) is formed, and the other surface is a flat surface (17). In addition, the first frame material (1
5), an engaging portion (18) for engaging and holding the flange portion (14) of the inner surface material (5) is provided at the end portion on the one surface side, and the outer surface material (6) at the end portion on the other surface side. A receiving portion (19) is formed to receive the flange portion (14). Since the first frame member (15) has two surfaces adjacent to each other, the inner surface material end portion is closer to the outer surface material end portion in the portion to which the first frame material (15) is attached. It is formed so as to be located inside by the distance P. And a notch
A second frame member (20) is attached to the end of (13). The second frame member (20) has two surfaces that are adjacent to each other at a right angle and has a groove (21) on one surface and a flat surface on the other surface, like the first frame material (15).
(22) are formed respectively. As shown in FIG. 6, the second frame member (20) has an inner surface member (5) at one end thereof.
An insertion portion (23) having a groove for inserting and holding the notched end portion of the outer surface member (6) is formed, and the notched end portion of the outer surface material (6) remains flat at the end portion on the other surface side. A locking portion (24) having a groove to be locked is formed. The depth of the groove of the engaging portion (24) is shallower than the depth of the inserting portion (23) as shown in FIG. further,
The notched end portion of the inner surface member (5) is formed so as to be located inside the notched end portion of the outer surface member (6) by a distance Q. In addition, the third frame member (8) or the fourth frame member is provided on the remaining flange portion excluding the notch (13) and the orthogonal connection.
Arrange (9) and shape the outer shape as a panel. Then, the undiluted foaming solution is foamed and filled from an injection port provided at an appropriate position to form a heat insulating material layer, and the ceiling panel (12) is formed. However, the pin body of the rotary lock (25) is provided in the concave portion of the third frame member (8), and the rotary lock (2) is provided in the convex portion of the fourth frame member (9).
The hook body of 5), the pin body of the rotary type lock (25) in the concave grooves (16) and (21) of the first frame member (15) and the second frame member (20) respectively on one side. At least one shall be provided.

On the other hand, as the side wall panel (3), the recess (1
0) Only the portion involved in formation is set to a size (width) according to the size of the recess, but a frame member is provided on the four end faces, and a convex portion is provided on at least the upper and lower end faces. A frame material (9) is provided. Of course at least one on each end face (eg 3 on the long side)
One, two on the short side) is provided with a rotary lock (25).

On the other hand, in the case of forming the L-shaped ceiling panel (26) in plan view in FIG. 2, notches are formed in the inner and outer surface materials so as to be L-shaped in plan, and the side edges excluding the notches. The flange is formed on the. As in the case of the U-shaped panel, the frame members and the double-sided members may be assembled and filled with the foamed heat insulating material.

In order to form the recess (10) for escaping the protrusion due to the presence of a pillar or the like, it is necessary to form the notch (11) for one panel, but in this example, the foaming process is completed. Rather than forming a notch by cutting out one rectangular panel, the notch (11) is formed in the panel production process, and the flange portion of the inner surface material (5) is replaced by the first frame material (15). Engaging part 18
And the flange portion of the outer surface member (6) is simply received by the receiving portion (19) of the first frame member (15) to engage the face member with the first frame member (15). The work is done only once, and the work of attaching the face material to the first frame member (15) can be greatly simplified.

Furthermore, the end of the U-shaped or L-shaped notch formed in the inner surface material (5) is inserted into the groove of the insertion portion (23) of the second frame material (20), and the outer surface material ( 6) For example, the end portion of the U-shaped or L-shaped notch is simply inserted into the groove of the engaging portion (24) of the second frame member (20) shallower than the groove of the inserting portion (23) and engaged. The second frame member (2
The work of inserting the face material into the inner surface member (0) is performed only at the notched end portion of the inner surface member (5), and the work of attaching the surface member to the second frame member (15) can be greatly simplified.

Further, by forming the concave groove (16) (21) to be connected to the convex portion of the side wall panel (3) in the frame material disposed on the end surface of the cutout portion of each face material, the uneven portion of the panel end surface is formed. Combined, the rotary lock (25) can firmly connect and fix the panels to each other, and it can be assembled without the need for a special connecting member, which can facilitate the assembly work and make the connecting part flat. it can. On the other hand, when viewed as a single panel, the end surface of the notch (11) is smooth, and the inner surface member (5) and the first frame member (15) and the second frame member (20) each have one surface. Since the surface positions of and are the same, a flat surface configuration can be performed as a whole, a notch can be formed at a desired position, and the panel can be used for a wide range of applications.

[Effects of the Invention] According to the present invention as described above in detail, the notch for the column escape is not formed by the notch work in the box assembly process, but the notch is formed in the panel production process. Therefore, the assembling work for forming the escape recess only requires the combination of the protrusion and the recess and the operation of the rotary type lock as in the other parts. Further, in forming the cutout portion, a cutout is formed in the inner and outer surface materials, the flange portion remaining on the inner surface material is engaged with the engaging portion of the first frame material, and the flange portion of the outer surface material is further changed to the first portion. The inner and outer surface members can be attached to the first frame member by simply receiving them in the receiving member of the frame member.
The number of times is sufficient, and the work of attaching the face material to the first frame member can be greatly simplified.

Further, the end of the U-shaped or L-shaped notch of the inner surface member is inserted into the groove of the insertion portion of the second frame member, and the U-shaped or L-shaped notch of the outer surface member is further inserted. The insertion work of the face material into the second frame member is performed only by inserting the end portion into the groove of the engaging portion of the second frame member, which is shallower than the groove of the insertion portion, and engaging the second frame member only with the notched end portion of the inner surface member. Also, the work of attaching the face material to the second frame member can be greatly simplified, and as a result, the panel production and assembly work becomes easy.
Further, the notch can be formed with a smooth surface by the second frame member having two surfaces that are adjacent to each other at a right angle, and
Since a rotary lock can be used as a connecting member with a panel to be connected vertically, the connecting connection can be made simple and strong, and the matching by combining with a conventionally used heat insulating panel is also good.
