Abstract
The anti-falling sheet reinforced lifting door comprises a door body, wherein the door body consists of a plurality of door sheets, each door sheet consists of a panel, a back plate and polyurethane foam adhesive filled in a cavity between the panel and the back plate, and a concave part is arranged at the joint of the left sides of the door sheets; the door is characterized in that a reinforcing plate is added at the concave position interface part inside the panel and the back plate, two ends of the reinforcing plate are provided with U-shaped hooks, and the U-shaped hooks extend into the U-shaped bending parts of the panel and the back plate respectively to hook the panel and the back plate. The utility model discloses an add a reinforcing plate at recess kneck at panel and backplate, not only can improve the intensity of door plant greatly, the wind resistance performance reinforcing, moreover indeformable, be difficult to tear, stop to take off a piece phenomenon, long service life, simple to operate.
Description
Technical Field
The utility model relates to a novel industrial garage door or lift gate door plant.
Background
At present, the door panels of the industrial lift doors manufactured in the whole industry are formed by filling a polyurethane foaming agent (filling material) into the interior of the door panels and bonding the door panels and the back panels after the color steel plates are extruded and molded to manufacture the face plates and the back panels of the door panels. The defects of the door plate are as follows: the panel and the back plate are simply bonded by the polyurethane foaming agent at the groove interface, are easy to split when in use, have the shedding phenomenon, are easy to move and dislocate, and influence the installation fastness and stability.
Disclosure of Invention
The utility model provides a structural strength is high, anti-wind, door plant non-deformable, tear and off-going
A lifting door is reinforced by anti-falling sheets.
The utility model discloses a realize through following technical scheme: the anti-falling sheet reinforced lifting door comprises a door body, wherein the door body consists of a plurality of door sheets, each door sheet consists of a panel, a back plate and polyurethane foam adhesive filled in a cavity between the panel and the back plate, and a concave part is arranged at the joint of the left sides of the door sheets; the door is characterized in that a reinforcing plate is added at the concave position interface part inside the panel and the back plate, two ends of the reinforcing plate are provided with U-shaped hooks, and the U-shaped hooks extend into the U-shaped bending parts of the panel and the back plate respectively to hook the panel and the back plate.
The width of the reinforcing plate is about 2 cm.
The reinforcing plate extends along the length direction of the face plate and the back plate and has the same length as the face plate and the back plate.
The reinforcing plate is made of a galvanized color steel plate.
The reinforcing plate is arranged on the inner side of the interface of the concave part of the face plate and the back plate.
The utility model discloses an add a reinforcing plate at recess kneck at panel and backplate, not only can improve the intensity of door plant greatly, the wind resistance performance reinforcing, moreover indeformable, be difficult to tear, stop to take off a piece phenomenon, long service life, simple to operate.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged view of fig. 1 at a.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, the anti-separation reinforced lifting door comprises a door body, wherein the door body is composed of a plurality of door panels 1, each door panel is composed of a panel 2, a back plate 3 and polyurethane foam 4 filled in a cavity between the panel and the back plate, and a concave part 5 is arranged at the left side joint of each door panel; the right side junction of door plant is provided with evagination 6, and panel and backplate are various steel sheet of zinc-plating. The panel and the back plate are respectively provided with U-shaped bends 2-1 and 3-1 at the interface of the inner recess 5, a reinforcing plate 7 is additionally arranged on the inner side of the interface of the inner recess 5, and U-shaped hooks 7-1 and 7-2 are arranged at the two ends of the reinforcing plate and respectively extend into the U-shaped bends of the panel and the back plate to firmly hook the panel and the back plate so as to prevent the phenomena of tearing and stripping.
