[0003] In order to fill the inside of the panel with a foam material, an injection hole having a diameter of 19 to 30 mm is formed in a frame material constituting one end of the panel, and the pressure inside the panel during the foam material injection and foaming is increased. In order to prevent this, an air vent hole having a diameter of about 3 mm was formed at an appropriate position in the panel frame. The injection of the foam material is performed by inserting a nozzle for foam injection into the injection hole, and after injection, the nozzle is removed and then closed by manually inserting a conical stopper or the like into the injection hole. Was done.

[0004]

After the injection of the foam material, the injection hole is sealed by inserting a plug, so that the foam material has a foaming pressure during the period from the removal of the nozzle to the insertion of the plug. As a result, it flowed out of the injection hole and adhered to the periphery thereof, which had to be removed manually.

[0005] Further, the air vent holes are usually provided at a plurality of locations, and the foam material also flows out from each of the air vent holes after the air leaks, and the foam material that has flowed out is solidified and the air vent holes are closed. Therefore, it is necessary to remove the foaming material attached to the outside of each hole after foaming, which not only wastes the foaming material but also requires a considerable amount of manual work, which hinders work efficiency. Was.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and therefore, a foaming material is injected into the interior space of a panel, and the finishing work after foaming is greatly reduced, and the working efficiency is reduced. It is an object of the present invention to provide a building wall panel having a structure that can be improved.

[0009]

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2
1 shows an example of a wall panel according to the present invention as a whole. In the illustrated embodiment, the wall panel 1 is formed in a vertically long rectangular shape, and is assembled so that the vertical direction is vertical. Both edges parallel to the longitudinal direction are joined side-by-side to adjacent panels. The upper, lower, left and right four circumferences of the panel 1 are formed of a rigid frame material, and the frame materials are connected to each other by welding or bolting at their ends to form a rectangular panel frame 2. The material of the frame material constituting the panel frame 2 is not particularly limited, but a metal material such as iron, stainless steel or aluminum material, for example, a U-shaped cross-section is preferably used as the frame material.

[0010] Inside the panel frame 2, if necessary, parallel to the short side of the panel 1, that is, the upper or lower side frame member 2b, for example, a pair of cross bars 3, 3 are provided at appropriate intervals. Mounted. These horizontal rails are made of a rigid material, and both ends of each horizontal rail 3 are fixed to the corresponding vertical frame member 2a of the panel frame 2 by welding or screwing.

The vertical frame member 2a and the horizontal frame member 2b constituting the panel frame 2 have the same height, and are usually
It is made of the same material. Face plates 4 and 5 constituting the indoor side surface and the outdoor side surface of the panel are fixed with the frame members interposed therebetween. Therefore, as shown in FIG. 2, the distance (H in FIG. 2) between the face plate 4 and the face plate 5 is determined by the height of the frame material, and the distance is maintained. Preferably, the frame member of the panel frame 2 and each of the horizontal rails 3 are made of a metal mold, and the height of the horizontal rail 3 is the same as the height of the frame members 2a and 2b. These cross rails 3, 3 reinforce the panel frame 2 and prevent distortion.

In the illustrated embodiment, a pair of cross rails 3, 3
It is most preferable that two horizontal rails 3 are provided with respect to the vertical dimension of the normal wall panel 1 because sufficient strength can be achieved with the minimum number of horizontal rails, but depending on various specifications or conditions, In some cases, the cross bar 3 may be omitted, or may be one, or three or more may be provided as desired. Preferably, the cross rail 3 is made of a frame material having the same material and the same cross-sectional shape as the frame material of the panel frame 2.
It is easier to manufacture and more favorable in strength. Further, in some cases, a vertical beam may be used as the beam.

The interior space 11, 11a, 11b of the hollow wall panel in which the face plates 4, 5 are fixed to the panel frame 2 is filled with the foam material 10, so as shown in FIG. Foam injection holes 6, 6a, 6b are formed at appropriate positions, for example, at the portion of the frame material 2a that constitutes one side of the panel 1. Air vent holes 7 are formed at appropriate positions of the panel frame 2, preferably at four corners as shown.

As shown in FIG. 3, the injection hole 6 made of a foam material is usually formed as a circular hole having a diameter of about 20 to 30 mm as in the prior art. A deformable and preferably flat sealing piece 8 is fixed,
The injection hole 6 is closed by the sealing plate piece. The sealing plate piece is fixed at one end to a part around the injection hole 6 by a suitable means, for example, by a double-sided adhesive tape or an adhesive. In FIG. 1, the injection hole 6 may be provided at an appropriate position according to the specifications of the panel 1, or may be provided at a plurality of positions as shown in FIG.

As is apparent from FIG. 3, the sealing piece 8 is formed to have a size that fits on the inner surface of the frame member 2 and may have any thickness. For example, the sealing piece 8 has a thickness of about 5 to 10 mm. Have. The material may be rubber, but any material may be used as long as it has elasticity and sealability. For example, a plate may be provided on one surface of an inelastic material which can be easily deformed. A spring may be attached.

Since the sealing piece 8 is fixed at one end to the periphery of the injection hole 6, a nozzle 9 for foam injection is inserted into the injection hole 6 as shown in FIG. Then, the sealing piece 8 is deformed following the nozzle, and when the nozzle is removed from the injection hole 6 after filling with the foam material, the sealing piece 8 is entirely resilient by its elasticity as shown in FIG. It returns to the original position in contact with the surface of the frame member 2 and closes the injection hole 6.

Each of the air vent holes 7 for preventing the pressure inside the panel from rising during foaming may have the same shape as the conventional one. Therefore, in one example, it is formed as a through hole having a diameter of about 3 to 5 mm. In this wall panel, as shown in FIGS. 1 and 5, an inner surface of each air vent hole 7 has an appropriate shape.
Preferably, as shown in FIG. 6, a formed fibrous body 12 formed in a flat plate shape is fixed, and the air vent hole 7 is closed by the fibrous body.

The fibrous body 12 is formed so as to have air permeability, and its shape is not particularly limited, but in one example, the fibrous body 12 is formed into a flat plate having an appropriate thickness, for example, a thickness of about 3 to 7 mm. And it can be formed as a moderately coarse or possibly random aggregate of filaments. The fixing of the fibrous body 12 to the area of the air vent hole 7 provided in the frame material is performed by any means such as an adhesive or a double-sided adhesive tape.

During manufacture, when the cross rail 3 is fixed to the panel frame 2 and the face plates 4 and 5 are mounted, the panel assembly is flat on a suitable support, that is, one face plate is placed on the surface of the support. And the upper surface thereof is held by a suitable pressing device on the face plate.
Insert At that time, the sealing piece 8 is deformed following the nozzle 9, and the tip of the nozzle 9 can be inserted into the panel 1. Therefore, a liquid foam material is injected into the interior space of the panel 1 through the nozzle 9 and foamed. At the time of foaming, air leaks from each air vent hole 7 through the fibrous body 12 to prevent an increase in air pressure inside the panel.

When a predetermined amount of foam is injected so as to cover the entire internal space of the panel 1 and the nozzle 9 is removed,
Since the sealing piece 8 elastically returns to the original position and closes the injection hole 6, the leakage of the foam material from the injection hole is prevented, and therefore, the outflow of the foam material from the injection hole 6 does not occur.

Further, since the air vent holes 7 are provided with the air-permeable fibrous body 12, not only the increase in the internal pressure due to the injection and foaming of the foam material, but also the panel 1
The foam material therein is prevented from flowing out by the fibrous body 12, or if it flows out, only a very small amount flows out. In addition, when the inside of the panel 1 is divided by the horizontal rail 3, the air vent hole 7 is provided in each sectioned area,
Preferably, air vent holes 7 are provided at four corners of each section.

As shown in the illustrated embodiment, the horizontal rails 3 are installed on the panel frame 2, so that the horizontal rails can appropriately prevent deformation and distortion due to pressure during foaming. In addition,
As the foaming material 10, a suitable foaming material such as urethane foam or styrol foam is used, and preferably, a foaming material having heat insulating properties is filled. This wall panel is filled with a foam material over the entire inner space surrounded by the panel frame 2 and the front and rear face plates 4 and 5, so that the panel frame 2, the horizontal rail 3 and the face plates 4 and 5 are integrally formed by the foam material. It has excellent strength due to reinforcement by the horizontal rail 3 having the same height as the frame material of the panel frame 2 if desired.

[0023]

As described above, according to the present invention, when the injection nozzle is removed after filling the foam material, the injection hole is immediately closed by the sealing piece attached to the injection nozzle. Does not flow out, and therefore the foam does not flow out and solidify through the injection hole. Also, there is no need to insert a plug into the injection hole as in the conventional case, reducing manual work,
Improve workability.

In addition, since a ventilated fibrous body is installed in the air vent hole for preventing an increase in the internal pressure of the panel at the time of foaming,
When the foaming material adheres to the fibrous body, outflow of the foaming material is suppressed as much as possible due to its viscosity and the like. Therefore, the work of cutting off the solidified foam material flowing out of the air vent hole can be remarkably reduced.
