Description

Technical Field

[0001] The invention relates to the field of decoration, and in particular to an EPS composite decorative component with a fireproof and flame-retardant structure. Background Art

[0002] EPS decorative components are mainly used in door frames, window frames, eaves lines, waist lines and courtyard columns of villas, European-style communities, hotels and commercial streets. Simple construction is an important advantage of EPS decorative components. No embedded parts or rivets are required during construction. Special bonding mortar can be used to directly bond them to the wall base. EPS components can be cut and spliced at will during construction, and can also be bonded to the outside of the exterior wall after the exterior wall insulation layer is completed.

[0003] When EPS decorative components are in use, since the EPS polystyrene foam material itself is flammable, its fire resistance is relatively poor and only meets the B1 flame retardant standard. In some occasions with high fire protection requirements, such as large public buildings, EPS may not meet the fire protection requirements, which may cause safety hazards in practical use and has shortcomings. Summary of the Invention

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0031] As Figures 1-7 shown, the EPS composite decorative member of the fireproof and flame-retardant structure proposed by the present invention includes a partition board 11, and positioning boards 12 are symmetrically installed at the ends of the partition board 11;

[0032] Corrugated boards 2 are arranged at intervals on the partition board 11. The EPS member includes an EPS frame 31 attached to the corrugated board 2, and the inner cavity of the EPS frame 31 is filled with an EPS filler 32;

[0033] The decorative part includes a fiberglass mesh cloth 41 covering the outer periphery of the combined whole of the partition board 11, the corrugated board 2 and the EPS frame 31, and a decorative layer 44 is arranged on the outer side of the fiberglass mesh cloth 41;

[0034] The self-locking mechanism includes a first bolt rod 51 and a rubber part 56 penetrating through the upper and lower parts of the combined whole of the partition board 11, the corrugated board 2, the EPS frame 31 and the decorative part, and a sealing plate 6 is connected to one end thereof penetrating through the back positioning board 12.

[0035] It should be noted that: The EPS frame 31 has a criss-cross frame structure. The hollow parts of the frame are evenly filled with EPS fillers 32. The EPS frame 31 and the EPS fillers 32 are formed separately. The directly formed EPS component is an integral structure and lacks mechanical support. When affected by external forces, the EPS component will undergo overall deformation. By forming the EPS component separately, first pour the EPS frame 31 with a criss-cross frame structure. The frame structure provides mechanical support, and fill the same material EPS fillers 32 in its hollow parts to play the shaping role of the EPS fillers 32 and ensure that the fillers in each hollow part are formed evenly.

[0036] It should be added that: The EPS frame 31 and the EPS fillers 32 are formed separately. During production, fireproof coatings can be sprayed or impregnated on the edges of the EPS frame 31 to form a fireproof and flame-retardant coating on its surface, solving the problem of synchronous combustion of the EPS frame 31 and the EPS fillers 32.

[0037] In this embodiment, the EPS component for decoration adopts a modular design. Each module is separated by a partition board 11. At the same time, the partition board 11 can also play the role of positioning before assembly. The combination of the partition board 11 and the positioning board 12 is an "L-shaped" structure as a whole;

[0038] Install the EPS component formed by the EPS frame 31 and the EPS fillers 32 in cooperation with the corrugated board 2 at the partition board 11. One layer is the EPS component and one layer is the corrugated board 2. The corrugated board 2 is a physical partition that blocks the spread of flames along the path of the EPS component;

[0039] The EPS frame 31 is provided in three sections in this application, including a front section, a middle section, and a rear section. Adjacent two EPS frames 31 are separated by the corrugated board 2. The combined module is a composite multi-layer structure. When the outer EPS frame 31 catches fire, its flame combustion boundary is the partition board 11 and the corrugated board 2, which can effectively prevent the overall combustion of the EPS frame 31 from causing collapse, improve the fireproof and flame-retardant performance, and at the same time improve the safety and stability of the EPS composite decorative component during use.

[0040] It can be understood that when manufacturing the EPS composite decorative component, multiple EPS frames can be set according to process requirements. It should be noted that the EPS frame 31 and the EPS fillers 32 are formed separately, and a corrugated board 2 needs to be set between adjacent EPS frames 31 to act as a physical partition.

[0041] In one embodiment, five groups of corrugated boards 2 are provided, and five groups of corresponding EPS frames 31 are provided. The combination of the corrugated boards 2 and the EPS frames 31 is installed at equal intervals between the corners surrounded by the partition board 11 and the positioning board 12. The purpose of this setting is that the end faces of the five groups of corrugated boards 2 attached to the partition board 11 can act as a five-fold flame-retardant structure, effectively improving the flame-retardant performance.

[0042] As Figure 3 and Figure 4 shown, there is an air gap left on the end face where the EPS frame 31 contacts the corrugated board 2, and the protrusion specifications of the front and rear end faces of the EPS frame 31 are the same.

[0043] Among them, the purpose of leaving an air gap between the corrugated board 2 and the EPS frame 31 is that when thermal expansion and contraction occur due to changes in high and low temperature environments, the air gap can compensate for the deformation of the EPS foam material. On the other hand, the air gap can be used for heat conduction between the EPS frame 31 and the corrugated board 2 at high temperatures to prevent the EPS frame 31 from being in a high temperature environment all the time.

[0044] As Figure 2 shown, the outer layer of the fiberglass mesh cloth 41 is coated with a separation layer 42, the outer layer of the separation layer 42 is coated with an adhesive layer 43, and the outer layer of the adhesive layer 43 is adhered with a decorative layer 44.

[0045] A decoration part is sleeved on the outer periphery of the module after a plurality of corrugated boards 2 and EPS frames 31 are combined, including a fiberglass mesh cloth 41, a separation layer 42, an adhesive layer 43, and a decorative layer 44 from the inside to the outside;

[0046] The fiberglass mesh cloth 41 itself has high temperature resistance and flame retardant properties, and its fiber material can improve the impact resistance and prevent the base layer from cracking;

[0047] The separation layer 42 is set by coating a flame retardant coating, and is used to block the transfer of the flame of the decorative layer 44 to the EPS foam;

[0048] The adhesive layer 43 is used for pasting the decorative layer 44, and a fireproof adhesive material with flame retardant properties is selected for coating;

[0049] The decorative layer 44 can be selected and installed according to process requirements, such as a stone decorative layer, a paint decorative layer, and a wood grain decorative layer.

[0050] As Figure 6 shown, one end of the first bolt rod 51 passing through the decorative layer 44 is a slotted structure, an axle holder 52 is installed in the slot, a shaft rod 53 passes through the middle of the axle holder 52, and a rotatable limit plate 54 is sleeved outside the shaft rod 53.

[0051] In one embodiment, the first bolt rod 51 is used to position the upper part of the overall combination of the partition plate 11, corrugated plate 2, EPS frame 31 and decorative part. An adaptive locking mechanism is provided at its front end. The limiting plate 54 can rotate on the shaft frame 52 through the shaft rod 53. A total of four groups of limiting plates 54 are provided. The unfolded limiting plate 54 is in a "cross" structure. Except for the fixation of the bolt rod 51 in the inner cavity, step-by-step limiting and reinforcement are carried out in the up, down, left and right directions at its end, effectively preventing the EPS composite decorative component from loosening and ensuring the stability of its combination. A gasket is installed in the gap between the "cross" structure limiting plate 54 and the decorative layer 44 to buffer vibration and prevent the first bolt rod 51 from loosening.

[0052] As Figure 7 shown, a rubber part 56 is provided on the end face of the second bolt rod 55 attached to the decorative layer 44. The rubber part 56 is a deformable part that deforms synchronously with the decorative layer 44.

[0053] Among them, the rubber part 56 is used for dynamic sealing of the lower part of the overall combination. The rubber part 56 can be attached to the special-shaped end face of the decorative layer 44 without specially designing corresponding fixing parts.

[0054] As Figure 1 and Figure 2 shown, the sealing plate 6 is used for the plug-in combination of the first bolt rod 51 and the second bolt rod 55 in the horizontal direction. The decorative layer 44 covers the outer periphery of several combined partition plates 11, corrugated plates 2, and EPS frames 31. Since the EPS composite decorative component is assembled by combining multiple modules, the positioning plates 12 on each partition plate 11 can serve as a combined structure. The sealing plate 6 cooperates with the first bolt rod 51 and the second bolt rod 55 protruding on the positioning plate 12 to assemble each module into one body, solving the splicing problem. Moreover, the sealing plate 6 is arranged behind the EPS composite decorative component and is a hidden design, maintaining the overall neat and beautiful appearance.

[0055] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principles of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
