Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 with figure 2 As shown, a schematic diagram of the existing sandwich composite panel connection structure is given, which includes an upper composite panel 1, a lower composite panel 2, a secondary structure 3, structural nails 4, an inner flange 5 and a sub-mouth flange 6; the upper composite panel 1 and the lower composite board 2 are provided with female ports and sub-ports, so as to realize the connection of two adjacent composite boards. The substructure 3 shown is fixed on the main structure of the building, and the upper composite board 1 and the lower composite board 2 are fixed on the substructure 3 through structural nails 4 . The sub-port flange 6 extends into the female port to realize the connection of the two composite panels. An inner flange 5 is provided on the inner side of the female opening of the upper com...

The invention discloses a sandwich composite plate middle-positioned double-support connection structure. A composite plate comprises a central core material and an outer protection plate. A mother port and a seam allowance for achieving connection of adjacent composite plates are arranged on the composite plate. The sandwich composite plate middle-positioned double-support connection structure is characterized in that the double-support connection structure comprises a first notch, a first protrusion, a second notch and a second protrusion, wherein the first notch, the first protrusion, the second notch and the second protrusion are arranged on the mother port and the seam allowance and the first notch is matched with the first protrusion and the second notch is matched with the second protrusion. A double support type connection manner of two adjacent composite plates is achieved by arranging two matched protrusions and two matched notches. Fastness of a joint of composite plates is ensured and cracking and stripping of the joint under the action of negative air pressure are avoided. The sandwich composite plate middle-positioned double-support connection structure has the advantages of being simple and reasonable in structure, obvious in benefit effect and convenient to apply and popularize.
Description
technical field [0001] The invention relates to a double-supported connection structure in the middle of a sandwich composite panel, more specifically, a double-supported connection structure in the middle of a sandwich composite panel with good negative wind pressure resistance. Background technique [0002] Sandwich composite panels have been used more and more in the field of construction. When sandwich composite panels are applied to building exterior walls, they are prone to cracking or falling off under the influence of negative wind pressure for a long time. The reason is that the matching structure between the adjacent upper and lower composite boards and the sub-ports is not perfect, as shown in the accompanying drawings figure 1 And and figure 2 As shown, the top of the lower composite board shown is fixed on the secondary structure 3 by structural nails 4. After the upper and lower composite boards are matched, under the influence of negative wind pressure, onl...
