Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnesium oxysulfate boards, and more particularly to a bent magnesium oxysulfate fireproof board. Background Technology
[0002] Magnesium oxysulfate board is an inorganic fireproof board made from magnesium oxide, magnesium sulfate, and water as raw materials. After being configured and modified, it serves as a cementing material, reinforced with medium-alkali or alkali-free glass fiber cloth, and mixed with lightweight fillers (perlite, sawdust). Due to its core advantages of fire resistance, lightweight, water resistance, and environmental friendliness, magnesium oxysulfate board is commonly used for building fire protection and partitions, as well as interior and exterior decoration. In order to meet the pursuit of streamlined, curved, and curved aesthetics and functions in modern architecture and design, there is a need for a bent-form magnesium oxysulfate fireproof board.
[0003] In the process of realizing this application, the inventors discovered the following problems with the existing technology: Existing magnesium sulfide fireproof boards are usually bent and shaped by factory prefabrication and on-site processing. When the board is not completely dry and cured in the factory, it is laid on a mold with a pre-designed curvature and pressed into shape. Then it is cured and dried for prefabrication. On-site processing is carried out by opening V-shaped grooves on the back of the parts that need to be bent, then bending, and finally treating the joints with caulking material. However, in these methods, factory prefabrication limits the bending angle and size, and on-site processing, although flexible, requires multiple processes, which affects construction efficiency.
[0004] Therefore, those skilled in the art have provided bent-formed magnesium oxysulfide fireproof boards to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a bent magnesium oxysulfate fireproof board that requires no on-site processing and can be bent according to the required bending angle.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A bent magnesium oxysulfate fireproof board includes two outer panels, both of which are rectangular and parallel vertically. A magnesium oxysulfate board is fixedly connected between the two outer panels. The magnesium oxysulfate board includes multiple support blocks, and bending blocks are fixedly connected between the intervals of the support blocks. The support blocks are thick plates, and the bending blocks are thin plates. Adhesive layers are provided between the upper and lower ends of the support blocks and the two outer panels. Trapezoidal holes are provided on the magnesium oxysulfate board near the two ends of the bending blocks.
[0007] Furthermore, each of the two outer panels is provided with a connecting groove near both sides. The connecting groove is L-shaped and is arranged laterally on both layers of the outer panel. A connecting plate is snapped into each connecting groove. Both ends of the connecting plate are L-shaped and fit into the connecting groove.
[0008] Furthermore, both outer plates are provided with retaining grooves near the support block. The retaining grooves are rectangular columnar channels used to fix the position by inserting rectangular columns inside when splicing them up and down.
[0009] Furthermore, a wear-resistant layer is fixedly connected to the outer surface of both outer plates.
[0010] This utility model has the following beneficial effects: The present invention proposes a bent magnesium oxysulfate fireproof board, in which two outer plates are connected to the inner magnesium oxysulfate board support block by an adhesive layer. The support block is a thick block, which is inflexible but has good rigidity and strength. The bending block is a thin plate, which has slightly lower rigidity and strength but better bending ability and can be directly cold-bent. The bending block is bent at a certain angle, which drives the support block to rotate at a certain angle. At the same time, the trapezoidal hole reserves a certain space for the corners of the support block. The two outer plates follow the bending and constrain the interior. With the thick block as support and the thin block as bending, the magnesium oxysulfate fireproof board does not need to be processed on site and can be bent according to the required bending angle.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Reference Figure 1 , Figure 4 One embodiment provided by this utility model: The bent magnesium oxysulfate fireproof board includes two outer panels 1, both of which are rectangular and parallel to each other vertically. A magnesium oxysulfate board 2 is fixedly connected between the two outer panels 1. The magnesium oxysulfate board 2 includes multiple support blocks 201. Bending blocks 202 are fixedly connected between the intervals of the multiple support blocks 201. The support blocks 201 are thick plates, and the bending blocks 202 are thin plates. Adhesive layers 8 are respectively provided between the upper and lower ends of the support blocks 201 and the two outer panels 1. Trapezoidal holes 6 are provided at both ends of the magnesium oxysulfate board 2 near the bending blocks 202.
[0015] Specifically, both outer panels 1 are rectangular plates and are directly parallel. The two outer panels 1 are directly and fixedly connected to a magnesium oxysulfate plate 2. The magnesium oxysulfate plate 2 includes multiple support blocks 201 and bending blocks 202. Each support block 201 is fixedly connected to a bending block 202. The support blocks 201 are thick plates, and the top and bottom surfaces of the thick support blocks 201 are fixedly connected to an adhesive layer 8. The magnesium oxysulfate plate 2 is fixedly connected to the two outer panels 1 through the adhesive layer 8. The bending blocks 202 are thin plates. As thin plates, the bending blocks 202 have good bending degree and can be directly cold-bent. When the bending blocks 202 bend at a certain angle, they can drive the support blocks 201 at both ends to rotate at a certain angle. At the same time, the reserved trapezoidal holes 6 provide a certain rotation space for the support blocks 201. When the support blocks 201 rotate, they will pull the outer panels 1 to bend at a certain angle, thereby forming an arc surface.
[0016] Reference Figure 2 , Figure 3 Two outer panels 1 are provided with connecting grooves 3 near both sides. The connecting grooves 3 are L-shaped and are arranged horizontally on the two layers of the outer panels 1. Each connecting groove 3 is fitted with a connecting plate 5. Both ends of the connecting plate 5 are L-shaped and fit with the connecting groove 3. Two outer panels 1 are provided with retaining grooves 4 near the support block 201. The retaining grooves 4 are rectangular columnar channels used to fix the position by inserting rectangular columns inside when splicing the upper and lower panels. The outer surfaces of the two outer panels 1 are fixedly connected with wear-resistant layers 7.
[0017] Specifically, the connecting groove 3 is L-shaped, and connecting grooves 3 are provided laterally on both sides of the two outer panels 1. Both ends of the connecting plate 5 are L-shaped and fit into the connecting groove 3. When the two magnesium oxysulfate fireproof boards are spliced left and right, the connecting plate 5 is snapped into the connecting groove 3 of the outer panel 1 between the two magnesium oxysulfate fireproof boards. Its L-shaped ends are snapped into the connecting groove 3 of the outer panel 1 between the two magnesium oxysulfate fireproof boards, thus splicing the two magnesium oxysulfate fireproof boards. The two outer panels 1 are close to each other. Each support block 201 is provided with a fixing groove 4, which is a rectangular columnar channel. When the two magnesium oxysulfate fireproof boards are joined together, the fixing grooves 4 on the outer plates 1 of the two magnesium oxysulfate fireproof boards fit together. The rectangular column can be inserted to fix the position between the two magnesium oxysulfate fireproof boards. The outer surfaces of the two outer plates 1 are fixedly connected with a wear-resistant layer 7, which is a melamine impregnated paper laminate. It is fixedly connected by hot pressing after being laid on the outer surfaces of the two outer plates 1.
[0018] Working principle: When the magnesium oxysulfate fireproof board needs to be bent, clean water is sprayed through the trapezoidal hole 6 onto the outer surface of the bending block 202 of the magnesium oxysulfate board 2, so that the outer surface of the bending block 202 is evenly moistened. The board is laid flat and left to stand for a period of time to allow the water to fully penetrate into the interior of the bending block 202, making it flexible. Then, the magnesium oxysulfate fireproof board is attached to the outer surface of the bending surface, and pressure is applied evenly by hand along the curvature of the bending surface. Secondly, the bending block 202 bends to a certain extent, causing the support block 201 to rotate at a certain angle. The bending of multiple bending blocks 202 to a certain extent forms a certain arc. At the same time, the trapezoidal hole 6 provides a certain rotation space for the support block 201. Multiple support blocks 201 are fixedly connected to the two outer plates 1 through the adhesive layer 8. The rotating support block 201 pulls the outer plate 1 to bend to a certain arc, making it fit the curved surface. When the magnesium oxysulfate fireproof board is completely fitted to the curved surface, the magnesium oxysulfate fireproof board is fixed through the retaining groove 4 passing through the rectangular column. Then... The material is naturally dried, and after a certain period of natural drying, it is completely dried and shaped. Then, the two outer plates 1 of the two magnesium oxysulfate fireproof boards are connected by the connecting plate 5 to the connecting groove 3, and the two magnesium oxysulfate fireproof boards are horizontally spliced together. The two magnesium oxysulfate fireproof boards are vertically spliced together by the rectangular column passing through the fixing groove 4 of the two outer plates 1. The bending block 202 is bent in sections to combine the arc and the support block 201 is used to connect the bending block 202, so that the magnesium oxysulfate fireproof board does not need to be processed on site and can be bent according to the required bending angle.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
