Description

Technical Field

[0001] This invention relates to the field of color-coated steel sheet technology, and in particular to an engineering-reinforced flame-retardant color-coated steel sheet. Background Technology

[0002] Color-coated steel sheet, also known as pre-coated steel sheet, refers to a product made by applying organic coatings to the surface of a steel strip substrate in a continuous production process and then baking it. As a composite material, color-coated steel sheet not only has high strength and is easy to form, but also has good corrosion resistance. At the same time, the organic coatings can be formulated into various colors, and various patterns such as wood grain and leather texture can be created with the help of printing, embossing and other techniques, giving color-coated steel sheet excellent decorative properties. Therefore, it has been increasingly widely used in construction, home appliances and transportation.

[0003] Existing color-coated steel sheets have poor fire resistance and cannot provide adequate fire protection in the event of a fire. Furthermore, the current method of connecting multiple color-coated steel sheets via bolts or welding is problematic. If the sheets are subjected to heavy impacts or vibrations during use, the bolted connections are prone to loosening or even breaking, failing to provide a stable connection and resulting in low safety. Welding, on the other hand, is complex, time-consuming, and inconvenient for disassembly and replacement during initial installation and subsequent maintenance. Summary of the Invention

[0004] Based on the technical problems existing in the background art, the present invention proposes an engineering-reinforced flame-retardant color-coated sheet, comprising:

[0005] The first plate and the second plate are respectively provided with a first fastener and a second fastener at one end, and the first plate and the second plate are detachably connected by the first fastener and the second fastener.

[0006] The first fastener includes two movable pins. One end of the first plate has a through hole arranged along the width direction of the first plate. Both movable pins are movably installed in the through hole, and an adjustable interlocking area is formed between the two movable pins. The two movable pins have a first working state and a second working state. When the two movable pins are in the first working state, both movable pins are located in the through hole. When the two movable pins are in the second working state, both movable pins extend out of the through hole.

[0007] The second fastener includes a prepositioning protrusion and a locking component. The prepositioning protrusion and the locking component are both located at one end of the second plate. The prepositioning protrusion can be inserted into the insertion area. When the prepositioning protrusion is inserted into the insertion area, both movable pins extend out of the through hole. The locking component is used to lock the position of the two movable pins at this time.

[0008] Preferably, the prepositioning protrusion has two inclined surfaces arranged in a figure-eight shape, and two movable pins are provided with slots communicating with through holes at one end of the first plate. The two inclined surfaces can be inserted through the slots into the insertion area.

[0009] Preferably, the locking component includes two movable frames, which are arranged along the width direction of the second plate and movably installed on both sides of the second plate, and the movable frames can move along the length direction of the second plate; the two movable frames are correspondingly arranged with two movable pins, the movable frames have a first engaging tooth and a moving tooth, the movable pins are provided with a second engaging tooth that engages with the first engaging tooth, and the second plate is provided with a driving component, which drives the movable frames to move through the moving tooth.

[0010] Preferably, the driving component includes a driving shaft that passes through the second plate and is threaded onto the second plate. Two gears are fixedly sleeved at both ends of the driving shaft. The two gears are distributed on both sides of the second plate and mesh with the moving teeth on the two moving frames respectively.

[0011] Preferably, the movable frame includes two parallel movable parts and a curved part connecting the two movable parts. A first engaging tooth is located inside the curved part, a second engaging tooth is located on the side of the movable pin away from the second plate, and a movable tooth is located inside one of the movable parts.

[0012] Preferably, the gear is located between two moving parts.

[0013] Preferably, each of the two moving parts on the same moving frame is provided with a limiting block mounted on the second plate. The two limiting blocks position the moving frame between the two plates, limiting its movement and ensuring stability.

[0014] Preferably, both the first and second panels have a fire-retardant magnesium oxide board layer inside. This is to enhance the flame-retardant and fire-resistant properties of the color-coated steel sheet.

[0015] Compared with existing technologies, the engineering-reinforced flame-retardant color-coated steel sheet proposed in this invention, using the above-mentioned technical solution, achieves the following technical effects:

[0016] 1. By setting the first fastener and the second fastener, the setting of the prepositioning protrusion in the second fastener can ensure the accuracy of the connection end face between the first plate and the second plate during the connection process of the first plate and the second plate. Under this premise, the first fastener and the second fastener can be connected in a stable and accurate manner.

[0017] 2. By setting locking components, after the first plate and the second plate are pre-positioned and connected by the pre-positioning protrusion, the locking component in the second fastener can simultaneously lock the two movable pin positions in the first fastener. It is convenient to use, has a good locking effect, and further improves the connection stability between the first plate and the second plate. Attached Figure Description

[0032] Reference Figure 1-11 This invention proposes an engineering-reinforced flame-retardant color-coated sheet, comprising:

[0033] First plate 1 and second plate 2, one end of the first plate 1 and the second plate 2 are respectively provided with a first fastener 3 and a second fastener 4, and the first plate 1 and the second plate 2 are detachably connected by the first fastener 3 and the second fastener 4.

[0034] Reference Figure 7 , Figure 9 The first fastener 3 includes two movable pins 31. One end of the first plate 1 has a through hole 5 arranged along the width direction of the first plate 1. Both movable pins 31 are movably installed within the through hole 5, forming an adjustable interlocking area between them. The two movable pins 31 have a first working state and a second working state. When both movable pins 31 are in the first working state, both movable pins 31 are located within the through hole 5, that is... Figure 1 In the indicated state, the first plate 1 and the second plate 2 are not connected; when the two movable pins 31 are in the second working state, both movable pins 31 extend out of the through hole 5, that is... Figure 2 In the state shown, the end faces of the first plate 1 and the second plate 2 are pressed together;

[0035] The second fastener 4 includes a pre-positioning protrusion 41 and a locking member 42. Both the pre-positioning protrusion 41 and the locking member 42 are located at one end of the second plate 2. The pre-positioning protrusion 41 can be inserted into the insertion area. When the pre-positioning protrusion 41 is inserted into the insertion area, both movable pins 31 extend out of the through hole 5, and the locking member 42 is used for locking. Figure 2 The positions of the two movable pins 31 in the state are adjusted to complete the connection between the first plate 1 and the second plate 2.

[0036] Reference Figure 7-9 The pre-positioning protrusion 41 has two inclined surfaces 6 arranged in a V-shape. Two movable pins 31 are located at one end of the first plate 1 and have slots 7 communicating with the through hole 5. The two inclined surfaces 6 can pass through the slots 7 and be inserted into the insertion area. Specifically: In Figure 1 In the indicated state, the first plate 1 is moved closer to the second plate 2, causing the pre-positioning protrusion 41 on the second plate 2 to pass through the slot 7 and be inserted into the insertion area. At this time, the two inclined surfaces 6 on the pre-positioning protrusion 41 will press against the two movable pins 21, which are moving out through holes 5 that are far apart from each other. (Refer to...) Figure 2 or Figure 5 The state shown; furthermore, the two movable pins 31 in this state can be locked by the locking piece 42, that is, the connection relationship between the first plate 1 and the second plate 2 will change to Figure 3 As shown.

[0037] Reference Figure 1-6 The locking component 42 includes two movable frames 8, which are arranged along the width direction of the second plate 2 and movably mounted on both sides of the second plate 2. The movable frames 8 can move along the length direction of the second plate 2. The two movable frames 8 are correspondingly arranged with two movable pins 31. The movable frames 8 have a first engaging tooth 9 and a moving tooth 10. The movable pins 31 are provided with a second engaging tooth 11 that engages with the first engaging tooth 9. A driving component is provided on the second plate 2, and the driving component drives the movable frames 8 to move through the moving tooth 10. Figure 5 In the indicated state, the driving component can drive the movable frame 8 to move to the right, which in turn drives the first engaging tooth 9 on the movable frame 8 to move to the right until it engages with the second engaging tooth 11 on the movable pin 31. At this point, the position of the movable pin 31 is fixed. For the first plate 1 and the second plate 2, they are first pre-positioned and connected by the pre-positioning protrusion 41. This pre-positioning connection ensures accurate positioning of the connection end faces of the first plate 1 and the second plate 2. Under this premise, the movable pin 31 will extend out of the through hole. Finally, the movable frame 8 locks the position of the movable pin 31, further improving the connection stability between the first plate 1 and the second plate 2 and making it convenient to use.

[0038] Reference Figure 1-6The driving component includes a drive shaft 12, which passes through the second plate 2 and is threaded onto the second plate 2. Two gears 13 are fixedly sleeved at both ends of the drive shaft 12, respectively distributed on both sides of the second plate 2, and meshing with the moving gears 10 on the two movable frames 8. It should be noted that since the drive shaft 12 is threaded onto the second plate 2, the two gears 13 will rotate along with the drive shaft 12 during rotation, and the two gears 13 will have a certain amount of displacement in the axial direction of the drive shaft 12. Therefore, the thickness of the gears 13 in the axial direction needs to ensure that the moving gears 10 always mesh with the gears 13.

[0039] Reference Figure 10 The movable frame 8 includes two parallel movable parts 81 and a curved part 82 connecting the two movable parts 81. A first engaging tooth 9 is located inside the curved part 82, a second engaging tooth 11 is located on the side of the movable pin 31 away from the second plate 2, and a movable tooth 10 is located inside one of the movable parts 81. A gear 13 is located between the two movable parts 81.

[0040] To ensure the stability of the mobile frame 8 during movement, limiting blocks 14 mounted on the second plate 2 are provided on the outer sides of the two moving parts 81 on the same mobile frame 8. The two limiting blocks 14 place the mobile frame 8 between the two and limit its movement to ensure stability.

[0041] To enhance the flame-retardant effect of the color-coated steel sheet, a fireproof magnesium oxide board layer is provided inside both the first sheet 1 and the second sheet 2.

[0042] For the overall configuration of either the first board 1 or the second board 2, it can be set as follows: Figure 11 As shown, the left and right ends are symmetrically provided with second fasteners 4 and first fasteners 3, and the connection between the two first plates 1 or the two second plates 2 is the same as in the above embodiment, which is convenient and stable.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
