Detailed Description

With reference to fig. 1 and 2, a manufacturing method of a reinforced color steel plate includes the following steps:

the method comprises the following steps: cutting the color-coated coil according to the required size and processing the color-coated coil into a color-coated plate 1, and collecting the cut excess materials;

step two: selecting surplus materials of a color coating coil and processing the surplus materials to form X rectangular color coating coils, wherein X is more than or equal to 2 and is an even number, bending the rectangular color coating coils from one end to form a jaw edge 5-1, then bending the rectangular color coating coils to form a connecting part 5-2, then bending the rectangular color coating coils to form a supporting part 5-3 according to the thickness of a core material 3, and then bending the rectangular color coating coils to form a connecting part 5-2, or bending two ends of at least two rectangular color coating coils to form a jaw edge 5-1, then bending the rectangular color coating coils from one end to form a connecting part 5-2, and then bending the rectangular color coating coils to form a supporting part 5-3 according to the thickness of the;

step three: laying a bottom color-coated sheet 5-1, fixing a frame 2 on the bottom color-coated sheet 1 by gluing, firstly placing a core material 3 into the frame 2, then placing a bent rectangular color-coated roll as a reinforcing piece 5 between the core materials 3 along the length direction of the color-coated sheet 1, in the placing process, combining two rectangular color-coated rolls into a group, mutually attaching the supporting parts 5-3 of the two rectangular color-coated rolls, and abutting the core material 3 against the jaw edge 5-1 to tightly attach the two rectangular color-coated rolls; meanwhile, when X is equal to 2, the length of the bent rectangular color coating roll corresponds to the distance between the front end and the rear end of the frame 2; when X is larger than 2 and the length of the bent rectangular color coating coil is smaller than the distance between the front end and the rear end of the frame 2, the two bent rectangular color coating coils are arranged in a staggered mode as a group, and the length direction of each group of bent rectangular color coating coils projected to the color coating plate 1 is overlapped;

step four: after the glue is coated, a top color-coated plate 1 is laid and placed under pressure.

Taking the most common 50-type metal surface sandwich board single glass as an example, the fireproof board 4 is a glass magnesium board with the thickness of 5mm, the two sides of the color steel board are color coated boards 1 (plates processed by color coated coils) with the thickness of 0.5mm, and the middle is rock wool. Firstly, utilizing a plate shearing machine to shear a part for manufacturing a color-coated plate 1 from a color-coated coil, processing the part into the color-coated plate 1, and collecting the residual materials of the color-coated coil sheared off; the height of the reinforcing piece 5 is 50-5-0.5-0.5=44mm according to the height of the rock wool, and 43mm is taken to prevent the defect of appearance caused by the fact that the height of the reinforcing rib is pushed to the color-coated plate; selecting collected excess materials, cutting the excess materials into long strips of 83mm, bending the long strips by a bending machine, respectively folding two ends of each long strip by a right-angle jaw edge 5-1 (for preventing rock wool strips from sliding into an inner cavity of a reinforcing part 5 in the production process) of 4mm and 90 degrees, folding one edge of 16mm and 90 degrees as a connecting part 5-2, and then folding one edge of 43mm and 90 degrees as a supporting part 5-3; or the jaw edge 5-1, the connecting part 5-2, the supporting part 5-3 and the connecting part 5-2 can be bent in sequence from one end; by adopting the bending step, the supporting part 5-3 can be ensured to be corresponding to the rock wool in height, the reinforcing effect is prevented from being influenced due to the fact that the connecting part 5-2 of the reinforcing part 5 is not tightly attached to the color steel plate, and the phenomenon that the reinforcing part 5 is marked on the surface to influence the appearance quality in the pressurizing process due to the fact that the color coated plate 1 is jacked is avoided.

The color-coated plate 1 is laid on the bottom, after the surface of the color-coated plate is coated with glue, a frame 2 is fixed, rock wool strips are placed in the frame 2 along the length direction of the frame 2, if the length of a reinforcement piece manufactured by bending corresponds to the length of the frame 2, the two reinforcement pieces 5 can be placed in the middle position along the length direction of the frame 2, and the rock wool strips respectively abut against jaw edges 5-1 from two sides of the reinforcement piece 5 so that supporting parts 5-2 of the jaw edges are attached and fixed in the frame 2; if the reinforcing members 5 are short, the reinforcing members are grouped into a group, each group is arranged in the frame 2 in a staggered mode and is fixed by the rock wool strips, and the projections of each group in the length direction have overlapping parts, so that the reinforcing members can play the same role as the whole reinforcing member. Then, a glass magnesium board is laid above the rock wool strips and the reinforcing pieces 5, and then the color-coated board 1 coated with glue is covered on the glass magnesium board and placed in a pressing mode, so that the related parts are bonded together.

Two color-coated roll reinforcing part supporting parts with the same manufacturing method are attached and arranged in a color steel plate, and the bending resistance of the color-coated roll reinforcing part is improved by combining the structure of the upper end and the lower end which are used for connecting the color-coated plate and the jaw edge which is used for preventing the rock wool strips from entering, so that the defect of insufficient thin strength of the color-coated roll can be overcome, and the requirement of 6.3.3-section bending resistance bearing capacity in the national standard GB/T23932-2009 is met. Compared with the C-shaped galvanized steel reinforcing rib adopted in the traditional color steel plate, the thickness of the C-shaped galvanized steel reinforcing rib is 0.6-0.7 mm, the thickness of the supporting part of the color-coated coil reinforcing part combined and arranged in the color steel plate is 1mm, the color-coated coil reinforcing part and the supporting part are respectively placed into a color steel plate with the length of 3700mm and the width of 1180mm under the same condition, 5 weights of 25kg are respectively and uniformly placed on the color steel plate for a deflection test, the deflection of the short side and the deflection of the long side of the color steel plate adopting the C-shaped galvanized steel reinforcing rib are 1.6mm and 3.53mm respectively; and adopt the various of combination formula to scribble and roll up the reinforcement, the various steel sheet minor face amount of deflection is 1.2mm, and the long limit amount of deflection is 2.93mm, and it can be seen that its various scribbles rolls up the reinforcement bending resistance of reinforcement and is superior to C type galvanized steel strengthening rib, simultaneously, compare I type strengthening rib, the reinforcement that adopts the waste material preparation still has light in weight and anticorrosive advantage, and the preparation method is simple and convenient, and the waste recycling can save a large amount of costs and can reduce the occupation of land.
