Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The invention relates to transparent sealed hollow panels for use in structural members, such as the roofs and side walls of greenhouses or also the windows of buildings.

Conventionally, this type of hollow panel has been transparent and made of extruded synthetic resin material such as polycarbonate, and has a pair of upper and lower surface walls facing each other at a predetermined distance;
Many parallel hollow parts are formed by the left and right side walls and the middle partition wall, which are installed in parallel between both front walls, but water and dust may enter the hollow parts of the panel. In order to prevent
Generally, the front and rear open ends of the panel are sealed.
Conventionally, the front and rear openings of a hollow panel were deformed by heating and melting, and then sealed by pressure-welding, but this required heat-fusion equipment, which increased equipment costs and It is necessary to seal the panels at the panel manufacturing factory, so the size of the sealed hollow panel is determined in advance, and it is not possible to cut the sealed hollow panel according to the size of the side walls or roof.
There was a problem in that this was completely impossible because the sealing properties of the panel would be impaired, and the flexibility was very poor. Moreover, if there are crimping parts at both ends of the hollow panel, it will not be possible to stably fit the panel into the groove of the frame member, and furthermore, thermal processing distortion will occur during crimping at the open end and remain. There were problems in that the strength was reduced and the durability was poor.

Therefore, the applicant proposed a sealed hollow panel in which the openings at both ends of the hollow panel body made of extruded synthetic resin were directly filled with a sealant to seal the openings at both ends (No. 60-27626). However, in the previously proposed sealed hollow panel, filling the opening at one end of the hollow panel body with a sealant can be easily done by, for example, a dipping method. When filling the end opening with sealant, since there is air in the hollow, the sealant cannot enter the hollow using the normal dipping method due to the action of air pressure, and the air pressure inside the hollow is removed. It is necessary to perform relatively troublesome filling work such as filling with sealant while
In addition, since the liquid sealant is filled into the openings at both ends of all the hollow parts, it takes a long time for the sealant to harden, resulting in poor workability.

Purpose of the invention The purpose of this invention is to solve the above problems and cut the hollow panel body made of extruded synthetic resin material to the required size at a construction site such as a greenhouse, and then open both ends of the hollow panel body on the spot. The parts can be sealed and formed in a short time with very simple work.
To provide a sealed hollow panel that has excellent workability and flexibility, has very good sealing properties, and can be stably fitted into a frame member.

Structure of the invention In order to achieve the above object, this invention consists of a pair of upper and lower surface walls facing each other at a predetermined interval, and a pair of left and right side walls and a center wall provided in parallel between both surface walls. It is equipped with a synthetic resin hollow panel body that is approximately rectangular when viewed from a plane and has a large number of parallel hollow parts formed by partition walls, and has an adhesive layer at the front and rear opening ends of the hollow panel body. The closing tapes are pasted in a U-shaped cross section so as to cover the front and rear openings of all the hollow parts, and the left and right ends of each tape are made to protrude outward from the left and right side walls of the hollow panel main body, U-shaped sealing material filling spaces are formed at each of the four corners of the hollow panel body when viewed from the side, and the sealant filled in these spaces seals both the front and rear edges of the left and right side walls of the hollow panel body, The gist is a sealed hollow panel that is closed with tape for end closure.

Embodiment Next, an embodiment of this invention will be described based on the drawings.

In this specification, front, back, left, right, and top and bottom are based on FIG. "" means the upper side of the figure, and "bottom" means the lower side of the figure.

1 to 3 showing a first embodiment of this invention, a sealed hollow panel 1 according to this invention has a pair of upper and lower surface walls 3, 3 facing each other at a predetermined interval, and both surface walls 3. , 3, the hollow panel main body 2 is approximately rectangular when viewed from a plane, in which a large number of parallel hollow parts 7 are formed by the left and right side walls 4, 5 and the intermediate partition wall 6, which are provided in parallel between the three members. We are prepared. The hollow panel main body is made of a transparent synthetic resin extrusion material such as polycarbonate, and is cut into a desired size. An end closing tape 8 made of aluminum foil having an adhesive layer on the inner surface is applied to the front and rear opening ends of the hollow panel main body 2 so as to cover the front and rear openings of all the hollow parts 7 in a U-shaped cross section. Attached to each tape 8
Both left and right end portions 18, 18 of the hollow panel body 2 are made to project outward from the left and right side walls 4, 5 of the hollow panel body 2. In this embodiment, the left and right edges of the hollow panel main body 2 are cut exactly at the center of the hollow part 7, and the upper and lower overhanging walls 13 are extended from the upper and lower surface walls 3, 3 on both the left and right sides of the hollow panel main body 2. , 13 are formed respectively. The upper surface portion 18a and the lower surface portion 1 of the left and right end portions 18, 18 of each tape 8 having a U-shaped cross section.
8b are attached to the outer surfaces of the ends of the upper and lower projecting walls 13, 13, respectively. As a result, the four corners of the hollow panel main body 2 are provided with side surfaces by the front and rear end portions 13a, 13a of the upper and lower overhanging walls 13, 13 and the bottom portions 18c, 18c of the left and right end portions 18, 18 of the tape 8, respectively. A sealing material filling space 10 is formed in a U-shape when viewed from above. A sealing material 11 made of silicone rubber is filled in each of the four corner spaces 10 to close the space between the front and rear edges of the left and right side walls 4 and 5 of the hollow panel body 2 and the end closing tape 8. The hollow panel main body 2 is completely sealed.

As the end closing tape 8, it is preferable to use an aluminum foil adhesive tape, especially from the viewpoints of ease of bending, resistance to wrinkles during pasting after bending, and weather resistance. , other adhesive tapes made of polyester, adhesive tapes made of polyvinyl, etc. can also be used. The thickness of these tapes 8 is usually 20 to 200 μm,
