The details are described in Application No. 642.474 filed Aug. 984, No. 201J.

FIG. 2 is an exploded view showing some of the main constituent elements used in the present invention, especially the expanded IIT used in the top and bottom of the present invention.
Details of a large example of the 11111 desired frame are shown below.

FIG. 2A shows the method of [stage and)j according to the present invention;
The finished product of the enclosure 59 having the closing portion 61 is shown as the final product.

The inner formwork 26 has six 7's corresponding to the large surface of the lJ, l latitude body.
The frame assembly is 41. Each 7-ram assembly involves four angle members, each of which is common to adjacent pond 7-ram assemblies.

All components of the 7-frame assembly are pre-positioned inside the shell member 12, which serves as the wall of the outer formwork.
A foam panel 3 (3) must be placed on the inner side. A closing portion 61 serving as an entrance/exit is formed in one of the panels.

As for the f-stage to open this treasure part in Yotsuogi, any known technique can be used to do this, and therefore the details will be omitted in Kikiri Hosogeki.

After the assembly for the inner formwork 26 is positioned within the shell member 12, each of the six seven-frame assemblies is fitted with a sheet 32, such as a nylon sheet. The means for airtightly sealing the joint tiIII region and a portion of the corner of these assemblies will be described later. A seven-frame assembly completely hermetically sealed with these nylon sheets constitutes the inner formwork of the present invention.

It will be readily understood that the same explanation applies to the pre and angle members.

In Figure tPJ3, the means for connecting various parts to form the inner formwork are reduced. At Uni, adjacent 2
Although only one link is described that applies to one 7 frame, it should be assumed that all other 7 frames are connected as well. After attaching the members for the frame to the panel to form a shelter, the seven frames formed by the angle members shown in No. 2, 1, and 1 are joined together, and the adjacent nylon fills! , a step is provided for joining the sheets to form an inner formwork, i.e.
As a result, an airtightly sealed inner formwork is formed that does not cause leakage from the joints even when gas is pressure-injected into the assembly constituting the inner formwork. This inner formwork is described in detail in the aforementioned US patent application Ser. No. 642.474.

The angle member 11 shown in FIG. 3 is shown separately as a representative of the angle member shown in FIG. 2, and consists of 13 and 15.

After positioning the angle member against the foam panel already in place, a stage is provided for hermetically sealing and receiving the nylon sheet.

A piece of nylon 17 with sealant 19.21 on both sides
is fitted onto the right-angled surface 13.15 of the angle member 11. This nylon piece 17 with a sealant is prepared in advance. These nylon pieces 7 with sealing material 19 and 21 are similarly VC bonded to each of the four angle members constituting the frame. This nylon piece 17 is bridged at a portion of the corner to provide strength.

Next, nylon sheets 23 and 25 are bonded to the scraps of the sealing material 21. Nylon sheet 2: After determining the position of 1n by spreading the 7-frame assembly with nylon sheet 2 so as to surround the angle member forming 6η, the nylon sheet 27 of S2 (I- The nylon sheets 2:) and 25'' are laminated and fixed. This use of the sealant and the nylon LJ/piece on each side of the nylon sheet ensures that the nylon sheet is properly bonded and avoids the risk of air leakage. The nylon pieces 27 are bridged at some corners to increase strength. By adopting such an arrangement, it is possible to avoid leakage in a part of the corner where the leakage path is extended through a plurality of sealing materials.

All corner portions of the angle members making up the frame assembly are joined in the same manner as shown in FIG. At the RFT corner where the three 7-frames meet the film notes, additional means are used to join the units of 3-2).

The method for joining these three units is shown separately in FIG. That is,;(two angle members (1, 3:(,
35 are arranged at regular intervals in the JL direction as shown in the figure, and the corner bracket 37 is fitted between the tape sections 39. 41 and 43 are pasted t1 so that they are in contact with each other.

These tape sections with double-sided sealant 39.41
．． 43 is a continuous tape-like member such as the above-mentioned sealing material [9.21] nylon piece [7] on both sides.

A portion of the corner of the nylon film sheet 45, 47, 49 is placed in contact with the sealing inner surface of the tape section 39, 41, 43. After placing the nylon film sheet, another corner piece with tape sections 51, 53, 55 is inserted. These tape sections 5
1.53.55 is coated with adhesive. These tape sections 51, 53, 55 are made of continuous nylon strips 27 with sealant 29 shown in FIG.
You can get it.

1: As explained above, according to the present invention, an appropriate airtight seal is provided not only at the location where the edges of the nylon sheets are joined, but also at the apex corner where the 7 frames 3 are joined. The sealing material is laminated to provide a strong seal that will not leak or burst when high pressures are applied to the inflatable assembly that makes up the inner formwork. It is possible to obtain a seal effect.

FIG. 5 shows the +ijf state in which the foam panels 52, 54 are joined, and as is clear from the illustration, these panels have beveled joint surfaces 56, 5, respectively.
8, and are joined at the rear oblique surfaces 56 and 58 to form a corner.

In order to provide a complete panel structure profile for these panel connections, 7 laps of 7 fiberglass are used on both the inside and outside of the panels.

The outer flap is a fiberglass component 60.62
Consists of. The inner flaps also consist of fiberglass sections 64,66 provided on panels 52,54, respectively.

Since fiberglass has low rigidity before being impregnated with resin, it is desirable to position the outer shell member 12 using helper sheets 6:3 when positioning the outer seven wraps 60,62. This helper sheet 68 becomes part of the outer formwork during the installation of adjacent panels, such as panels 52 and 54, into position, but is removed after these panels have been positioned. The inner 7 eyeglass 7 laps 64', 66 are kept folded as shown in Figure 5 until the joining of a part of the corner is completed, and after the joining is completed they are unfolded as shown in Figure 7. The two end edges overlap each other in a range that sufficiently covers the panel joining area.

The panel 52 has an outer fiberglass coating 70 and an inner fiberglass coating 70.
Similarly, the panel 54 has an outer fiber glass arytenum 74.
The same applies to other panels that are not shown in the figure.This 7 fiberglass cover 11 that wraps around the panel may be attached to the inner lllllll part depending on the case. and the outer part,
This may be configured as a continuous river member.

The fll'sFi diagram reduces another 1°r constant of panel dark blue -1, and here Y'?゛-shaped aluminum plate 78 is inserted into the corner Hf) between the panels.

Money! This L-like Y-shaped tool 7 ;i has 11. It is used to abut the inner surfaces of adjacent panels to integrate them so that they can accommodate the internal or external loads used. That is, this Y-shape prevents "scraping" that can occur between the foam core of the panel and the inner and outer a-coatings at some of its corners. As a result, the rigidity of the panel, which is attached to a portion of the corner, is increased to HP.

FIG. 7 shows a 7-wrap fiberglass fiberglass fi 4.66 unrolled to completely cover Y7: shape 78. .: As clearly shown here, the joining area of adjacent panels is fully reinforced by using a 7-eye glass flap with a camber outside 11111.

(Effects of the Invention) According to the present invention described above, in a hollow surrounding body assembled from FM number of panels in which the foam core material is completely covered with reinforcement #a such as fiberglass, the reinforcing fibers Since the material is resin-cured, it is possible to easily obtain a single-piece enclosure with high rigidity and excellent airtightness and heat resistance.
