Description

Technical Field

[0001] The utility model relates to a building material, in particular to a reinforced steel plate structure prefabricated plate. Background Art

[0002] In our daily lives, prefabricated panels are often used to construct buildings such as mobile homes, factories, temporary dormitories, outposts, and watchrooms. Due to the diverse environments in which these buildings operate, new requirements are placed on the panels' flexural and impact resistance. Patent 202420030679.8 proposes a prefabricated panel with a special-shaped steel plate structure that can withstand certain flexural and impact forces. However, as the length of the prefabricated panel doubles, its span also doubles. The special-shaped steel mesh structure alone cannot withstand the weight of the prefabricated panel itself or external impacts. Summary of the Invention

[0003] In order to solve the problems existing in the above technologies, the utility model provides a method of adding a special-shaped keel in a special-shaped steel plate structure to support the weight of the prefabricated plate itself and resist the impact of external forces.

[0004] A reinforced steel plate structure prefabricated panel comprises an upper shell, a lower shell, a keel and a filler. The upper shell and the lower shell are buckled together to form a hollow prefabricated panel shell. The keel is fixed at equal distances in the hollow prefabricated panel shell to prevent the upper shell and the lower shell from sinking inward due to their own weight or impact of external force. The prefabricated panel shell is filled with filler to form a reinforced steel plate structure prefabricated panel.

[0005] The keel is installed between the upper shell and the lower shell to support the space formed by the buckling of the upper shell and the lower shell, and to strengthen the ability of the prefabricated panel to resist deformation and bending due to its own weight and external pressure or impact force. The keel is made of stainless steel plates, aluminum plates and iron plates with special-shaped structures, and the special-shaped structures include rectangular grooves and wavy grooves.

[0006] The left end of the prefabricated panel shell is provided with an inward-sunken docking port A, and the right end of the prefabricated panel shell is provided with an outward-convex docking port B. The docking port A of one prefabricated panel is docked with the docking port B of another prefabricated panel to form a prefabricated panel assembly of different areas.

[0007] The left and right ends of the upper shell are respectively provided with a first pair of joints and a second pair of joints, and the left and right ends of the lower shell are respectively provided with a third pair of joints and a fourth pair of joints. The first pair of joints, the second pair of joints, the third pair of joints and the fourth pair of joints are all U-shaped joints, the openings of the first pair of joints and the third pair of joints are inward, the openings of the second pair of joints and the fourth pair of joints are outward, the second pair of joints and the fourth pair of joints with the openings outward are connected to each other, and the first pair of joints and the third pair of joints with the openings inward are connected to each other, so that the two ends of the upper shell and the lower shell buckling body form a docking interface A and a docking joint B outward, and a filling space is formed in the buckling body.

[0008] The filling space is filled with a filler, and the material of the filler can be foamed concrete, gypsum, lime or cement concrete.

[0009] The upper shell and the lower shell are both made of metal materials, including stainless steel plates, aluminum plates, and iron plates; the shapes of the stainless steel plates, aluminum plates, and iron plates can be flat plates or wavy special-shaped plates.

[0010] The number of the keels arranged in the prefabricated panel shell can be selected from 0 to 5 according to the span of the prefabricated panel shell.

[0011] The docking modes of the docking interface A and the docking joint B include zigzag docking and wedge docking. The prefabricated panels are docked end to end to form a composite panel, and multiple panels are docked according to the actual needs of the building area.

[0012] The beneficial effect of the utility model is that it can effectively resist the self-weight and external force impact caused by the exponential increase in the span of the prefabricated board. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 5-9As shown, the keel 13 is installed between the upper shell 11 and the lower shell 12, and is used to support the space formed by the buckling of the upper shell 11 and the lower shell 12, and to strengthen the ability of the prefabricated plate to deform and bend due to its own weight and the action of external pressure or impact force.
