Description

Composite board

The utility model relates to a composite board.

Known as the new patent case of Taiwan No. 83214055 "Insulation Composite Panel Structure", its structure is an upper steel plate and a bottom film, and the upper and lower layers are tightly bonded into one by the middle PU (polyurethane) foam layer , and there is no PU foaming agent on the lower edge of the high protrusion on one side of the steel plate, so as to facilitate the lap joint of the two heat-insulating composite panels; but with this structure, after a long period of use, the upper and lower panels of the composite panel With the bonding of the foaming agent, there will be cases of falling off, and it cannot be matched with automatic continuous production, which is time-consuming and laborious in assembly and molding; another example is No. 86210746 "Structure Improvement of Modular Wall Panel" designed by the designer of this case "Taiwan's new patent case, its overall structure is a three-layer structure as shown in Figure 1, that is, it is composed of upper and lower boards and PU foaming agent between them. The vertically bent joint surface is used to limit the foaming direction of the PU foaming agent. The top ends of the two joint surfaces are bent inwards to a folded edge at a perpendicular angle to the joint surface so that the upper plate body is covered on the folded surface. On the side, the upper and lower boards are tightly combined with the viscosity generated by the PU foaming agent at the same time; according to this structure, the lack of the above structure is improved, but in actual use, it is found that it still has lap joints. The fit is not enough, there will still be water seepage, the effect of wind pressure resistance is not good, and the bonding strength of the boards is not enough, and the exterior of the boards after lapping is not beautiful enough, etc., and needs to be further improved.

The purpose of the utility model is to provide a combination board, the combination of each layer of boards is tight, the overall structural strength is high, the structure is simple, the assembly is easy, it is suitable for automatic continuous production, and the production cost can be reduced.

The technical scheme of the utility model is:

A composite panel, comprising: an integrally formed upper panel, an integrally formed lower panel, and a polyurethane foam layer arranged between the upper and lower panels; it is characterized in that:

The two sides of the upper panel are bent downward to form a vertical plate, and the surface of the vertical plate is provided with a concave groove, and the two sides of the lower panel are respectively bent upward to form a convex joint surface and a concave joint surface. There are opposite grooves on the upper edge of the shaped joint surface and the concave joint surface; the vertical plates on both sides of the upper panel cover a section of the upper edge of the convex joint surface and the concave joint surface overlapping on both sides of the lower panel, so that the groove is embedded in the positioned in the groove.

The feature of the composite board is that an elastic rubber pad is provided between the overlapping convex and concave joint surfaces of the two overlapping composite boards.

The utility model has the following effects:

The utility model provides a combined panel, the upper and lower panels are covered and overlapped with each other, and the grooves and grooves are embedded and positioned with each other, which can increase the combination of the upper and lower panels and the overall structural strength of the board, so as to increase the closeness. and aesthetically pleasing.

When the two combined panels of the utility model are overlapped, an elastic rubber pad can be arranged between the convex joint surface and the concave joint surface, so as to have the effects of preventing seepage, preventing capillarity and resisting wind pressure.

The combined panel of the utility model has a simple structure and is easy to assemble. Since the upper and lower panels are integrally formed, automatic continuous production can be implemented to achieve the effect of reducing costs.

In order to have a further understanding of the utility model, the structure, features and achieved effects of the utility model will be described in detail below in conjunction with the illustrated preferred embodiment.

First, please refer to FIG. 2 , a composite panel provided by the present invention is composed of an upper panel 10 , a lower panel 20 and a PU (polyurethane) foam layer 30 therebetween.

As shown in Figures 2 and 3, the upper panel 10 is a flat plate structure, and vertical plates 11 are bent downwards on its two side edges, and corresponding grooves 12 are provided at appropriate positions on the vertical plates 11 on both sides; The panel 20 is also a flat plate, and its two side edges are respectively bent upwards to form a convex joint surface 21 and a concave joint surface 22. Corresponding grooves 23 are provided at the overlapping positions, which can be used for embedding and positioning of the above-mentioned grooves 12, so that the upper and lower panels 10, 20 can be combined more closely; and the PU foam layer 30 is formed by the upper and lower panels 10, The coating of 20 is limited to foaming, and the upper and lower panels 10, 20 are closely combined by the viscosity generated by the PU foaming layer 30 during foaming.

Please refer to shown in Fig. 4, in order to increase the structural strength of the composite panel 1 of the present utility model in actual use, guide grooves 13, 24 of any shape are imposed on the surfaces of the above-mentioned upper and lower floor panels 10, 20, in addition to strengthening the panel body Excellent structural strength, also has the effect of convenient drainage.

Please continue to refer to shown in Figure 5 and 6, which represent the implementation state schematic diagram of the composite panel of the present utility model in the actual lap joint operation; it can be clearly seen from the figure that because the composite panel 1 of the utility model is formed by The vertical plates 11 on both sides of the upper panel 10 cover a section of the upper edge of the convex joint surface 21 and the concave joint surface 22 overlapping on both sides of the lower panel 20, and make the concave groove 12 embedded in the groove 23. At the same time, And add an elastic rubber pad 25 between the convex joint surface 21 and the concave joint surface 22 that the two composite panels 1 join, and its both sides are in the form of outward expansion, so that when the two composite panels 1 are overlapped, If the external wind pressure is greater, the elastic rubber pad 25 will be closer to the panel, so it can resist higher wind pressure, and the composite panel 1 body will not have the situation that the upper and lower panels 10, 20 are detached. , and is different from the traditional combined boards composed of upper, lower, left and right boards, which may fall off, and it is more beautiful from the appearance, and the elastic rubber pad 25 can achieve anti-corrosion Infiltration, anti-capillarity and anti-wind pressure effect; moreover, the grooves 12 on the vertical plates 11 on both sides of the upper panel 10 and the corresponding grooves 23 on the convex and concave joint surfaces 21, 22 on both sides of the lower panel 20, It is beneficial to the tightness of the upper and lower panels 10, 20 when they are combined, and can effectively prevent the upper and lower panels 10, 20 from falling off. At the same time, the integrated design of the upper and lower panels 10, 20 cooperates with automated continuous Production can also reduce costs to meet economic benefits.

In addition, the composite plate 1 of the present utility model can also form an empty groove 26 between the convex and concave joint surfaces 21, 22 when the left and right sides are overlapped, so that the bolt can bolt the plate and the steel beam, and The bolt heads are not exposed, so as to achieve an aesthetic effect, as shown in Figure 7.
