Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a board member for construction, which includes a surface material, a backing material, and a foam material, and has interlocking connecting portions on both side edges of the surface material.

Conventionally, as a construction board member having sound insulation and heat insulation properties and suitable for the outer wall of a building, for example, as shown in FIG. A surface material 6 made of a metal plate of an appropriate length formed by integrally bending the rib portions 2, 3 and plug-type connecting portions 4, 5 extending therefrom in a direction parallel to the surface portion 1; It is constructed by integrally combining a synthetic resin foam T filled in the space surrounded by the upper parts 2 and 3 and a flexible backing material 8 superimposed on the foam T. Architectural components made of such materials are known.

For such construction members, the raw material for the foam T is usually fed while the facing material 6 is turned over and fed in one direction, and then the backing material 8 is layered on top of the material and then sandwiched in a caterpillar type mold. It is manufactured by foaming in the foam and forming it into a predetermined shape. In this case, the upper and lower facing mold members constituting the molding mold are arranged in parallel and move in one direction while maintaining an interval approximately equal to the height of the surface material 6, but the male mold that becomes the insertion edge There is inevitably a difference between the height A on the side of the connecting part 4 of the mold and the height B on the side of the connecting part 5 of the female mold, which becomes the insertion groove, and if this is suppressed by sandwiching it with parallel mold members. Disadvantages such as compressing and deforming the side of the female type connecting part 5 or creating a gap on the side of the male type connecting part and causing the foam T to protrude.
There was a coincidence. Furthermore, it is not necessarily efficient to manufacture - number of strip-shaped architectural board members with one manufacturing device.

The present invention solves these problems, improves manufacturing efficiency by simultaneously forming two architectural board members in parallel, and also compresses and deforms the surface material as described above or creates a gap between it and the mold member. The purpose of this invention is to provide a manufacturing device that can sufficiently expand and expand the foam by inserting it into the opposing portions of the mold members that move in one direction without causing any foaming. It is something.

In order to achieve this object, the present invention provides a surface material having a surface portion, rising portions extending toward the back side of both side edges thereof, and male and female connecting portions extending from these portions substantially parallel to the surface portion. 2. By means of a connecting part that serves as a connecting part of the above-mentioned male mold, which consists of a foam filled in the void on the back side of the maple and a lining material layered on top of the foam. In manufacturing equipment, two facing materials are formed in parallel and integrally, and two architectural board members are formed in parallel at the same time. The mold in which the foam is formed is formed by a mold member consisting of a flat endless band of metal, and a drum wrapped around the mold member at the front and rear is formed into a medium-height drum. It is characterized in that the vertical distance between both end edges of the mold member can be increased.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Two surface materials 6, 6 are continuously molded by a connecting portion 9 which becomes a male connecting portion 4, 4, and are formed in parallel and integrally. It is formed by a bending device (not shown) while being fed out from a reel, and placed upside down on a conveyor 11 consisting of a large number of trochanters, and fed in the length direction at a constant speed, if necessary, by a preheating device (not shown). After preheating with

The raw material 10 foams inside the surface material 6 which is sandwiched between the surface materials 21 and moves together with these materials to form a foamed body 7. Mold member 20, 2
1 is made of stainless steel or carbon steel, and has a smooth surface with a protective layer such as a rust-preventive or anti-corrosive plating layer, a silicone resin layer, etc. for molded products, and a layer with good peelability as required. It is composed of an endless band and is wound around drums 23, 24, 25, and 26 arranged in the front and rear, respectively.

The drums 23, 2 at the front in the direction of movement of the mold 22
5 is driven by a prime mover (not shown), and the rear drums 24, 25 are supported by movable bearings so that the tension of the mold members 20, 21 can be adjusted. Each drum 23,2
4, 25, and 26 have a length slightly larger than the width of the mold members 20, 21, and are made to have a medium height.

That is, as shown in FIG. 3, both ends are tapered to gradually become smaller in diameter, and both ends 28 are made smaller in diameter than the central part 27, or
Alternatively, the entire drum is shaped like a drum, and between the front and rear drums, restraining members 29 and 30 consisting of a group of rolls are arranged in the part where the mold 22 is formed, and the upper and lower mold members 20 and 21 are held horizontally. and supported in parallel. In addition, injection pipes 31 and 32 are arranged to blow heated air on the back surfaces of the mold members 20 and 21 toward the part where the mold 22 is to be formed, and in the center of the mold member 21 further below, a heat-resistant rubber tube is arranged. A protrusion 33 made of a stretchable material such as the above is attached over the entire length or partially, and the raised portions 2, 2 at the center of the metal plate are held between the protrusions 33 so as not to shift in the width direction. Ru. The surface material 6 and the backing material 8 are sandwiched between upper and lower mold members 20 and 21 that face each other at a distance approximately equal to the height of the male connecting portion 4, that is, the connecting portion 9, in the molding die 22, and are integrated therewith. The raw material 10 is heated and foamed to fill the void surrounded by the facing material 6 and the backing material 8 to form a foamed body 7b, and the mold member 20 is inverted along the drums 23 and 25. ,2
It is sent out from between 1.

Next, the connecting portion 9 is cut at the center and subjected to necessary bending processing to form the male connecting portion 4, and further cut to a predetermined length to obtain a product. In FIG. 3, the holding member 30 of the lower mold member 21 is arranged to completely support the mold member 21, which has a width larger than the width of the two integrated facing members 6, 6, on the drum 25,
26, and the holding member 29 of the upper mold member 20 is connected to the female mold connecting portions 5 at both ends.
The mold member 20 is supported by a roll having a length approximately equal to the uniform diameter central portion 27 of the drums 23 and 24.

In the embodiment of FIG. 4, the holding member 29 of the upper mold member 20 is
is constituted by rolls having approximately the same length as the drums 23 and 24, and has tapers that gradually become smaller in diameter at both ends, and both ends 29b are formed with a smaller diameter than the center part 29a.

That is, the upper mold member 20 can extend the distance from the lower mold member 21 by extending to both side edges, and is formed at both ends of the two surface materials 6, 6 that are integrated in parallel. Even if the female joints 5, 5 are higher than the central joint 9, the upper mold member 9 will not compress or deform the joints 9 and the female joints 5, 5 or separate from them. You can contact them without any hassle.

Of course, a plurality of nozzles 17 of the raw material supply device 12 can be arranged in parallel for one surface material 6, and the shape can be arbitrarily formed such as a round hole or a long hole, or the raw material 10 can be sprayed or It may also be supplied by means such as gravity flow.

Furthermore, the heating furnace 19 and either or both of the upper and lower injection pipes 31, 32 may be omitted, and the foam 7 may be formed at room temperature and pressure. Furthermore, it is preferable that the foam 7 of the plate member produced by the apparatus of the present invention is made of thermoplastic synthetic resin among polymeric materials, and in particular, urethane resin is used and the backing material 8 is made of asbestos. When paper is used, excess polyether remains in the urethane resin on the contact surfaces, which softens the surface layer of the urethane resin and buffers and absorbs any slippage that may occur between it and the mold member 20. There is no possibility of damaging the backing material 8 or causing cracks in the foam body 7. Furthermore, the aggregates to be added as necessary include borax, borates such as sodium meta-borate, silicates such as sodium silicate and sodium meta-silicate, phosphates such as diphosphoric acid sorter; phosphates such as sodium meta-phosphate, etc. Inorganic substances that have the property of foaming and expanding when heated to a temperature below the heat resistance temperature of the foam 7, or inorganic substances that do not have foaming and expanding properties such as aluminum hydroxide, alumina, silica sand, soda carbonate, and silica; furthermore, glass fibers, Examples include inorganic short fibers such as rock wool, barite grains, inorganic foam particles such as cellular glass, and other known flame retardants, and one or more of these may be used as appropriate. As described above, the present invention has a mold member that is arranged vertically facing each other, moves in one direction, and forms a foam therein by a mold member consisting of a flat endless band of metal. Since it is a medium-height drum with mold members wrapped around it before and after, the upper and lower mold members that move in one predetermined direction in the area where the mold is to be formed are moved by the medium-height drum. It is naturally moved toward the center to prevent horizontal wobbling and is moved in a straight line without meandering, and therefore there is no unnecessary space D between this mold member and the surface material and backing material. This eliminates the inconvenience of causing damage to them.

In particular, according to the present invention, since two architectural board members are integrated and formed in parallel at the same time, the manufacturing time is reduced compared to the conventional method in which one strip-shaped architectural board member is manufactured using one device. This dramatically improves efficiency.

As mentioned above, the mold member is wrapped around the middle-height drum in the front and rear directions, and the gap between the edges on both sides can be expanded by the mold part, so that the mold member that touches the middle part of the middle-height drum can be expanded. The central part contacts the connecting part of the two facing materials, and the mold member can be bent at both side edges to follow the connecting part of the female mold and contact the same, so that the facing material is compressively deformed or vice versa. By sandwiching the foam between the mold members without creating any gaps, the foam can be sufficiently formed without any protrusion. For this reason, together with the fact that the mold member does not meander, it is possible to produce high-quality architectural board members in a predetermined shape without the inconvenience of damaging the backing material or tearing it due to excessive tension acting on it due to foaming pressure. can be manufactured continuously and with high efficiency.
