[0001] This invention relates to the field of inorganic color steel plate technology, specifically to a color steel plate with excellent heat insulation effect and its production process. Background Technology

[0002] Color-coated steel refers to pre-painted steel sheets. Pre-painted steel sheets are steel sheets with an organic coating. They have advantages such as good corrosion resistance, bright colors, beautiful appearance, convenient processing and forming, and the original strength of steel sheets, as well as lower cost.

[0003] In existing technologies, insulated sandwich panels are installed inside color steel sheets to achieve thermal insulation for buildings constructed with color steel sheets. However, traditional color steel sheets have limited dimensions, usually requiring multiple sheets to be assembled on-site. After aligning two adjacent sheets, holes are drilled, and then rivets or screws are used to fix the two sheets together. On-site construction efficiency is low, and when the color steel sheets need to be recycled after dismantling, the original drilling positions affect reuse. Furthermore, traditional color steel sheets lack a flame-retardant structure inside, so if a fire breaks out in the insulated sandwich panels inside the color steel sheet, the fire can easily spread.

[0041] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figures 1 to 2 , Figure 4 This invention provides a technical solution: a color steel plate with excellent heat insulation effect, comprising an insulated sandwich panel 1, a color steel plate shell 2 sleeved on the outside of the insulated sandwich panel 1, an aluminum foil core layer 3 between the insulated sandwich panel 1 and the color steel plate shell 2, a flame-retardant plastic box 5 inserted into the surface of the insulated sandwich panel 1, the inside of the flame-retardant plastic box 5 containing fire extinguishing and flame-retardant powder, and a window 6 on the surface of the flame-retardant plastic box 5. The two sides of the insulated sandwich panel 1 are respectively provided with an assembly groove 18 and an assembly block 19 for assembling and fixing two adjacent insulated sandwich panels 1. The surface of the assembly groove 18 is provided with a positioning slot 20, and a positioning insert 22 is movably inserted into the surface of the assembly block 19, and a plug 26 is inserted into the inside of the assembly block 19. When assembling two sets of insulated sandwich panels 1, the assembly block 19 is inserted into the corresponding assembly slot 18, and the plug plate 26 pushes the positioning insert plate 22 into the corresponding positioning socket 20. After assembling two adjacent insulated sandwich panels 1 through the assembly block 19 and the assembly slot 18, the plug plate 26 is inserted into the assembly block 19 to push the positioning insert plate 22 into the positioning socket 20, thereby fixing the two insulated sandwich panels 1 after assembly. In addition, a flame-retardant plastic box 5 is added inside the insulated sandwich panel 1 to hold fire extinguishing and flame-retardant powder, thereby improving the flame-retardant performance of the color steel plate. This further solves the problem of low on-site assembly efficiency and poor flame-retardant effect of existing color steel plates. It can improve the on-site construction efficiency of color steel plates and improve the flame-retardant performance of color steel plates.

[0044] Example 2

[0045] See attached document Figure 5 , Figure 6 , Figure 8 as well as Figure 9 Based on Embodiment 1, in order to configure flame-retardant material inside the thermal insulation sandwich panel 1, the aluminum foil sandwich layer 3 has an annular plate structure. The outer ring surface of the aluminum foil sandwich layer 3 is fixed in the outer ring surface of the color steel plate shell 2. The surface of the thermal insulation sandwich panel 1 has multiple reserved openings 4, which are arranged side by side. The flame-retardant plastic box 5 is inserted into the reserved openings 4. The flame-retardant plastic box 5 has a square frame structure. Window 6 is opened on each of the four side plates of the flame-retardant plastic box 5. Hot melt film 7 is fixed on the surface of the window 6. Sealing plate 11 is fixed at the slot end of the flame-retardant plastic box 5. Space is reserved between the sealing plate 11 and the slot of the flame-retardant plastic box 5.

[0046] After inserting the flame-retardant plastic box 5 into the reserved opening 4, if a fire breaks out in the insulation sandwich panel 1, the high temperature will melt the hot melt film 7, and the fire extinguishing and flame-retardant powder contained inside the flame-retardant plastic box 5 will leak out through the window 6. After the fire burns the insulation sandwich panel 1 around the flame-retardant plastic box 5, a gap will appear between the flame-retardant plastic box 5 and the insulation sandwich panel 1. At this time, the fire extinguishing and flame-retardant powder will leak out through the window 6 and cover the flames. Compared with the current situation where fire rescue cannot be achieved in time, the fire extinguishing and flame-retardant powder leaking out through the window 6 and covering the flames plays a certain role in controlling the fire and preventing the fire from spreading over a large area. In addition, the flame-retardant plastic box 5 not only serves to store the fire extinguishing and flame-retardant powder, but also improves the bending resistance of the insulation sandwich panel 1 when installed in the insulation sandwich panel 1. That is, the flame-retardant plastic box 5 has multiple uses and richer functionality; it further solves the problems of low on-site assembly efficiency and poor flame retardant effect of existing color steel plates; it can improve the on-site construction efficiency of color steel plates and improve the flame retardant performance of color steel plates.

[0047] Example 3

[0048] See attached document Figure 3 , Figure 14 , Figure 15 , Figures 17 to 19, on the basis of the second embodiment, in order to fix the flame-retardant plastic box 5 inserted into the internal of the insertion reserved port 4, a plurality of slot-filling pieces 9 are fixed on the surface of the flame-retardant plastic box 5. The slot-filling pieces 9 are inserted into the first notch 8. The first notch 8 is opened on the surface of the insulation sandwich panel 1. A positioning insertion rod 10 is fixed on the surface of the slot-filling piece 9, and the positioning insertion rod 10 is inserted on the surface of the first notch 8; on the two relatively distributed side walls at the notch end of the flame-retardant plastic box 5, insertion ports 12 are opened. A positioning insertion rod 13 is inserted into the internal of the insertion port 12. One end of the positioning insertion rod 13 passes through the insertion port 12 and is inserted on the surface of the reserved port 4. The other end of the positioning insertion rod 13 is fixed on the surface of the push block 14. The push block 14 is slidably connected in the notch of the flame-retardant plastic box 5; a finger groove 15 is opened on the surface of the push block 14. The finger groove 15 is a "U"-shaped groove. A reserved groove 16 is opened at one end of the push block 14 away from the positioning insertion rod 13. An elastic support frame 17 is fixed on the surface of the reserved groove 16. The elastic support frame 17 is a "square" plate-shaped structure. The elastic support frame 17 is fixed between the two groups of push blocks 14, and both long sides of the elastic support frame 17 are circular arc-shaped panels.

[0049] When the flame-retardant plastic box 5 is inserted into the reserved port 4, the push block 14 needs to be removed from the notch of the flame-retardant plastic box 5 in advance. The specific operation is as follows: two fingers are respectively dug at the finger grooves 15 on the surfaces of the two push blocks 14, and the two fingers are closed. At this time, the two push blocks 14 squeeze the elastic support frame 17 to generate elastic deformation until the positioning insertion rod 13 on the surface of the push block 14 is pulled out from the insertion port 12. At this time, the push block 14 is pulled out to the outside of the flame-retardant plastic box 5; then the end of the flame-retardant plastic box 5 equipped with the sealing piece 11 is passed through the reserved port 4 until the slot-filling piece 9 is completely inserted into the first notch 8. At this time, the positioning insertion rod 10 is inserted on the surface of the first notch 8. In this way, the flame-retardant plastic box 5 will not slip out of the reserved port 4 randomly. In order to reinforce the connection between the flame-retardant plastic box 5 and the insulation sandwich panel 1, the following operations are carried out: after inserting the positioning insertion rod 13 on the surface of a group of push blocks 14 into a group of insertion ports 12, push the push block 14 so that the positioning insertion rod 13 passes through the insertion port 12 and is inserted on the surface of the reserved port 4. Then squeeze and push the other group of push blocks 14 to squeeze the hot-melt film 7 until the positioning insertion rod 13 on the surface of the other group of push blocks 14 can be inserted into the insertion port 12, and dial the other group of push blocks 14 to drive the positioning insertion rod 13 to be inserted on the surface of the reserved port 4. In this way, the flame-retardant plastic box 5 is fixed in the reserved port 4, and the elastic support frame 17 elastically supports between the two groups of push blocks 14 to avoid the problem that the positioning insertion rod 13 falls off from the surface of the reserved port 4 caused by the two groups of push blocks 14 approaching; further solves the problems of low on-site assembly efficiency and poor flame-retardant effect of the existing color steel plates; can improve the on-site construction efficiency of the color steel plates and enhance the flame-retardant performance of the color steel plates.

[0050] Embodiment Four

[0051] Refer to the appendix Figures 10 to 13 、 Figure 16, on the basis of Embodiment 3, in order to fix adjacent two thermal insulation sandwich panels 1 after assembly, the length of the long side of the assembly groove 18 is equal to the length of the long side of the color steel plate shell 2, the length of the long side of the assembly block 19 is equal to the length of the long side of the assembly groove 18, the height of the assembly block 19 is equal to the height of the assembly groove 18, the assembly block 19 is in a "匚"-shaped plate structure, and a space is reserved between the assembly block 19 and the color steel plate shell 2 for inserting the plug plate 26; positioning sockets 20 are provided on both the top surface and the bottom surface of the assembly groove 18, the length of the long side of the positioning socket 20 is less than the length of the long side of the assembly groove 18, mounting openings 21 are provided on both the top surface and the bottom surface of the assembly block 19, the size of the mounting opening 21 is equal to the size of the positioning socket 20, the positioning plug 22 is movably inserted into the mounting opening 21, inclined surfaces 23 are provided at both ends of the positioning plug 22, and a through hole 24 is provided on the surface of the positioning plug 22, an elastic rubber band 25 is inserted into the inside of the through hole 24, the middle of the elastic rubber band 25 is fixed on the surface of the through hole 24, and both ends of the elastic rubber band 25 are respectively fixed on two parallel side walls of the mounting opening 21; a connecting strip 28 is fixed on the surface of the plug plate 26, the connecting strip 28 is movably inserted into the second notch 27, the second notch 27 is provided on the surface of the assembly block 19, a screw 29 is screwed on the surface of the connecting strip 28, after the plug plate 26 is inserted into the assembly block 19, the connecting strip 28 is inside the second notch 27, and the screw 29 passes through the connecting strip 28 and is screwed on the surface of the second notch 27.

[0052] Before adjacent two thermal insulation sandwich panels 1 are assembled, the elastic rubber band 25 is in an initial state inside the through hole 24. At this time, the end of the positioning plug 22 provided with the inclined surface 23 is inserted into the assembly block 19, that is, the other end of the positioning plug 22 does not protrude from the mounting opening 21. After the two thermal insulation sandwich panels 1 are brought closer, the assembly blocks 19 on the surface of one group of color steel plate shells 2 are inserted into the assembly grooves 18 on the surface of the other group of color steel plate shells 2. When the two color steel plate shells 2 are aligned, the plug plate 26 is inserted into the assembly block 19. During this process, the plug plate 26 presses the positioning plug 22 along the inclined surface 23, the positioning plug 22 slides along the mounting opening 21, and the elastic rubber band 25 is stretched and deformed elastically during the movement of the positioning plug 22. When the plug plate 26 is completely inserted into the assembly block 19, at this time, the connecting strip 28 is inserted into the second notch 27, and the plug plate 26 blocks between the two groups of positioning plugs 22. The positioning plug 22 passes through the mounting opening 21 and is inserted into the positioning socket 20, completing the connection of adjacent two color steel plate shells 2, thereby realizing the connection and fixing of the two thermal insulation sandwich panels 1. Then, the screw 29 is passed through the connecting strip 28 and screwed on the surface of the second notch 27, thus preventing the plug plate 26 from falling off the assembly block 19; further solving the problems of low on-site assembly efficiency of the existing color steel plates and poor flame retardant effect; improving the on-site construction efficiency of color steel plates and enhancing the flame retardant performance of color steel plates.

[0053] Embodiment 5

[0054] Based on Example 4, a production process for color steel sheets with excellent heat insulation effect is proposed. The process includes the following steps:

[0055] Aluminum foil sandwich layer 3 is pre-fixed on the inner ring surface of the color steel plate shell 2. After the insulation sandwich panel 1 is inserted into the color steel plate shell 2, the aluminum foil sandwich layer 3 is sandwiched between the insulation sandwich panel 1 and the color steel plate shell 2 to form a heat insulation structure, thereby improving the heat insulation performance of the insulation sandwich panel 1.

[0056] During the processing of the thermal insulation sandwich panel 1, multiple reserved openings 4 are reserved on the surface of the thermal insulation sandwich panel 1 for the installation of flame-retardant plastic boxes 5. The flame-retardant plastic boxes 5 can be installed on site. The flame-retardant plastic boxes 5 are designed to be detachable, which facilitates the replacement of the flame-retardant plastic boxes 5 later. The flame-retardant plastic boxes 5 are filled with fire extinguishing and flame-retardant powder. In the event of a fire in the thermal insulation sandwich panel 1, the fire extinguishing and flame-retardant powder is used to reduce the fire.

[0057] When multiple sets of thermal insulation sandwich panels 1 need to be assembled, after two adjacent thermal insulation sandwich panels 1 are assembled through the assembly groove 18 and the assembly block 19, the plug plate 26 is dragged into the assembly block 19, and the plug plate 26 pushes the positioning insert plate 22 into the positioning socket 20 to complete the connection and fixation of the two adjacent thermal insulation sandwich panels 1.

[0058] In actual use, after inserting the flame-retardant plastic box 5 into the reserved opening 4, if a fire breaks out in the insulation sandwich panel 1, the high temperature will melt the heat-melting film 7, and the fire-retardant powder inside the flame-retardant plastic box 5 will leak out through the window 6. After the fire burns the insulation sandwich panel 1 around the flame-retardant plastic box 5, a gap will appear between the flame-retardant plastic box 5 and the insulation sandwich panel 1. At this time, the fire-retardant powder will leak out through the window 6 and cover the flames. Compared with the current situation where fire rescue cannot be achieved in time, the fire-retardant powder leaking out through the window 6 and covering the flames plays a certain role in controlling the fire. To prevent the fire from spreading widely, the flame-retardant plastic box 5 not only stores the fire-retardant powder, but also improves the flexural strength of the insulation sandwich panel 1 when installed inside it. Thus, the flame-retardant plastic box 5 serves multiple purposes and has richer functionality. When the flame-retardant plastic box 5 is inserted into the reserved opening 4, the pusher block 14 needs to be removed from the slot of the flame-retardant plastic box 5 beforehand. The specific operation is as follows: Place two fingers on the finger grooves 15 on the surfaces of the two pushers 14 respectively, and close the two fingers together. At this time, the two pushers 14 press against the elastic support frame 17 to produce... The push block 14 undergoes elastic deformation until the positioning rod 13 on its surface is pulled out of the socket 12. At this point, the push block 14 is pulled out to the outside of the flame-retardant plastic box 5. Then, the end of the flame-retardant plastic box 5 with the sealing plate 11 is passed through the reserved opening 4 until the patch plate 9 is fully inserted into the notch 8. At this point, the positioning rod 10 is inserted into the surface of the notch 8, so the flame-retardant plastic box 5 will not slide out of the reserved opening 4 at will. In order to strengthen the connection between the flame-retardant plastic box 5 and the insulation sandwich panel 1, the following operation is performed: a set of positioning rods 13 on the surface of the push block 14 are inserted into a set of After inserting into the socket 12, push the push block 14 to make the positioning rod 13 pass through the socket 12 and be inserted into the surface of the reserved opening 4. Then push another set of push blocks 14 to squeeze the hot melt film 7 until the positioning rod 13 on the surface of the other set of push blocks 14 can be inserted into the socket 12. Move the other set of push blocks 14 to make the positioning rod 13 be inserted into the surface of the reserved opening 4. In this way, the flame-retardant plastic box 5 is fixed in the reserved opening 4, and the elastic support frame 17 is elastically supported between the two sets of push blocks 14 to avoid the problem of the positioning rod 13 falling off the surface of the reserved opening 4 due to the two sets of push blocks 14 being close together.Before assembling two adjacent insulated sandwich panels 1, the elastic rubber band 25 is in its initial state inside the through-hole 24. At this time, one end of the positioning insert 22 with the inclined surface 23 is inserted into the assembly block 19, that is, the other end of the positioning insert 22 does not protrude from the mounting opening 21. After the two insulated sandwich panels 1 are brought close together, the assembly blocks 19 on the surface of one set of color steel shell 2 are inserted into the assembly grooves 18 on the surface of another set of color steel shell 2. When the two color steel shell 2 are aligned, the plug 26 is inserted into the assembly block 19. During this process, the plug 26 presses the positioning insert 22 along the inclined surface 23. Sliding along the mounting opening 21, and with the elastic rubber band 25 undergoing elastic deformation during the movement of the positioning insert 22, after the plug plate 26 is fully inserted into the assembly block 19, the connecting strip 28 is inserted into the second notch 27, and the plug plate 26 is positioned between the two sets of positioning inserts 22. The positioning inserts 22 pass through the mounting opening 21 and are inserted into the positioning insert 20, completing the connection between the two adjacent color steel plate shells 2, thereby achieving the connection and fixation of the two thermal insulation sandwich panels 1. Then, the screw 29 is screwed through the connecting strip 28 onto the surface of the second notch 27, thus preventing the plug plate 26 from falling off the assembly block 19.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
