Abstract
Description
Technical Field
[0001] The invention relates to a circular rod coated with an intumescent fire retardant coating, in particular to an exterior decorative component applied to the circular rod coated with the intumescent fire retardant coating. Background Art
[0002] Circular structural members are a common type of member in building interiors. To enhance their fire resistance and protect them from high temperatures, they are often coated with an intumescent fire retardant coating. This coating expands and foams at high temperatures, forming a fire-resistant and heat-insulating protective layer. However, after application, the coating leaves an uneven surface, significantly detracting from the interior's visual appeal. Therefore, there is an urgent need to develop a decorative component that can enhance the interior's aesthetics without interfering with the coating's foaming properties. Summary of the Invention
[0003] The present invention aims to provide an exterior decorative component for a circular rod coated with an intumescent fire retardant coating. The present invention can effectively improve the indoor appearance without affecting the foaming and expansion of the intumescent fire retardant coating.
[0004] The technical solution of the present invention is: an external decorative component used for a circular rod coated with an intumescent fire retardant coating, comprising a circular steel structure rod and an intumescent fire retardant coating layer, an annular decorative component layer being provided outside the intumescent fire retardant coating layer, and a leveling strip in contact with the intumescent fire retardant coating layer being further provided on the inside of the annular decorative component layer; the annular decorative component layer comprises two or more decorative components spliced together, and connecting clips are provided between adjacent decorative components.
[0005] In the aforementioned external decorative component for a circular rod coated with an intumescent fire retardant coating, both ends of the decorative component are provided with connecting bayonet holes, and the inner side wall of the decorative component is provided with a rubber strip connecting port.
[0006] In the aforementioned external decorative component for a circular rod coated with an intumescent fire retardant coating, both ends of the connecting clamp are provided with clamping blocks that match the connecting bayonet.
[0007] In the aforementioned exterior decorative component for a circular rod coated with an intumescent fire retardant coating, the annular decorative component layer comprises two interconnected decorative components, each having a semicircular cross-section. The decorative components are arranged symmetrically, with the entire 360° circle divided in half, thereby reducing the number of molds.
[0008] In the aforementioned exterior decorative component for a circular rod coated with an intumescent fire retardant coating, the decorative component has three rubber strip connection openings on its inner wall. The angle between adjacent rubber strip connection openings is 60°, and the angle between the connecting tab and adjacent rubber strip connection openings is 30°. This 30° angle between the connecting tab and adjacent rubber strip connection openings effectively utilizes the leveling rubber strips. The rubber strip connection openings are spaced at 60° intervals because the decorative component will be uneven after application of intumescent fire retardant coating. Without leveling rubber strips, hollowing and wobble of the decorative rod may occur.
[0009] In the aforementioned external decorative component for a circular rod coated with an intumescent fire retardant coating, the melting point of the material of the connecting clip is less than or equal to the temperature at which the intumescent fire retardant coating expands thermally.
[0010] Compared with the prior art, the present invention provides an annular decorative component layer composed of two or more decorative components on the outside of the intumescent fire retardant coating, thereby wrapping and covering the intumescent fire retardant coating, which can effectively improve the aesthetics of the circular structural columns in the room and enhance the visual experience; moreover, by providing a leveling strip on the inside of the annular decorative component layer to fill the gap between the coating and the decorative component, and having a certain elasticity, the annular decorative component layer is prevented from hollowing and shaking. At the same time, the decorative components are connected and fixed by connecting clips, and the melting point of the material of the connecting clips is less than or equal to the temperature of the intumescent fire retardant coating when it is thermally expanded, so that the decorative components can automatically fall off when heated, and will not affect the foaming and expansion of the intumescent fire retardant coating. In summary, the present invention can effectively improve the indoor visual experience without affecting the foaming and expansion of the intumescent fire retardant coating.

[0014] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.
[0015] Example. An external decorative component for a circular rod coated with an intumescent fire retardant coating, comprising: Figure 1-2As shown, it includes a circular steel structure rod 1 and an intumescent fire retardant coating layer 2, an annular decorative component layer is provided outside the intumescent fire retardant coating layer 2, and a leveling strip 5 in contact with the intumescent fire retardant coating layer 2 is also provided on the inside of the annular decorative component layer; the annular decorative component layer includes two or more decorative components 3 spliced together, and connecting clips 4 are provided between adjacent decorative components 3.
[0016] The decorative component 3 is provided with connecting bayonet holes 31 at both ends, and a rubber strip connecting hole 32 is provided on the inner side wall of the decorative component 3 .
[0017] Both ends of the connecting clamp 4 are provided with clamping blocks that match the connecting clamp port 31 .
[0018] The annular decorative component layer includes two decorative components 3 spliced together, and the cross section of the decorative component 3 is a semicircular structure.
[0019] The inner wall surface of the decorative component 3 is provided with three rubber strip connection openings 32 , the angle between adjacent rubber strip connection openings 32 is 60°, and the angle between the connecting bayonet 31 and the adjacent rubber strip connection opening 32 is 30°.
[0020] The melting point of the material of the connecting clamp 4 is less than or equal to the temperature at which the intumescent fire retardant coating material expands thermally.
[0021] Circular structural columns are circular steel structural members.
[0022] The decorative components are made of aluminum alloy.
[0023] The connecting tabs on the decorative component are connected to the connecting clips, and the melting point of the connecting clips is less than or equal to the temperature at which the intumescent fire retardant coating expands. This allows the decorative component to automatically fall off when heated without affecting the foaming and expansion of the intumescent fire retardant coating.
[0024] The cross section of the rubber strip connection port is a T-shaped structure. The leveling rubber strip is provided with a notch that matches the rubber strip connection port, and leveling support angles are provided at both ends of the inner side of the leveling rubber strip.
[0025] The installation process of the present invention is as follows: first, the intumescent fire retardant coating is sprayed on the surface of the circular structural column, and then the leveling strip is set at the strip connection port, and then the two decorative components are placed around the outer surface of the cylindrical structural column so that the connection bayonet ports at the adjacent ends of the two decorative clips correspond to each other, and the two ends of the connection clip are inserted into the two connection bayonet ports to realize the connection of the two decorative components.
[0026] In the event of a fire, since the melting temperature of the connecting clips is lower than the expansion temperature of the intumescent fire retardant coating, the connecting clips will melt first due to the heat, causing the two decorative components to lose the connection function of the connecting clips and fall off; then, when the temperature reaches the expansion temperature of the intumescent fire retardant coating, the intumescent fire retardant coating will begin to expand, providing high-temperature resistance protection for the circular structural rods.
