detailed description

The technical scheme of the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, and the described specific embodiments are only for explaining the utility model, and are not intended to limit the utility model.

As shown in Figure 1 and Figure 2, the utility model proposes a new type of composite wallboard, its structure is: the composite wallboard includes a main steel keel frame, and the main steel keel frame includes a frame and an intermediate keel.

The frame is composed of upper frame beam C-shaped purlin 4, lower frame beam C-shaped purlin 5, left frame beam C-shaped purlin and right frame beam C-shaped purlin welded together, and the upper frame beam C-shaped purlin 4 goes down Buckle, the lower frame beam C-shaped purlin 5 buckles upwards, and the left frame beam C-shaped purlin and the right frame beam C-shaped purlin are oppositely buckled.

The middle keel of the middle keel comprises a horizontal keel 6 and a vertical keel 7, and the horizontal keel 6 and the vertical keel 7 are mutually welded to form an integral steel keel frame; the space between the horizontal keel 6 and the vertical keel 7 The inside is filled with rock wool boards 3 wrapped by vapor barrier membranes 2. The outer flange of the vertical keel 7 is provided with a heat-insulating keel 11 with a thickness of 20-25 mm. The width of the heat-insulating keel 11 is the same as the width of the flange of the vertical keel 7. The middle keel and the The sum of the thicknesses of the heat insulation keels is the same as the thickness of the frame, as shown in Figure 2.

As shown in FIG. 2 , self-tapping screws 12 are used to fix the cement fiber board 1 , the heat insulation keel 11 and the middle keel.

As shown in Figure 1, the upper frame beam C-shaped purlin 4 and the lower frame beam C-shaped purlin 5 are provided with embedded parts 8 and 9, and the upper frame beam C-shaped purlin 4 is also provided with a hook 10;

The composite wallboard is provided with door and window openings, and C-shaped purlins welded to the main body steel keel frame are arranged along the periphery of the door and window openings.

Embodiment: The composite wall panel includes a main body steel keel frame, which is made of C-shaped purlins. The C-shaped purlins of the beam are buckled opposite to each other, and horizontal and vertical keels are arranged in the middle.
