[0001] This application relates to the technical field of rock wool boards, and particularly to a heat-insulating rock wool board. Background Art

[0002] Rock wool boards are made of basalt and other natural ores as the main raw materials. The rock wool boards are melted into fibers at high temperature, added with appropriate binders, and cured and processed to form a new type of heat-insulating, fire-separating, and sound-absorbing material.

[0003] The invention patent with the publication number CN105888085A proposes a heat-insulating rock wool board; the heat-insulating rock wool board is composed of a rock wool layer, upper and lower mesh structure layers respectively arranged on the upper and lower surfaces of the rock wool layer, and connecting pieces. The connecting pieces penetrate the rock wool layer and connect the upper and lower mesh structure layers.

[0004] For the above-mentioned heat-insulating rock wool board, through the mesh structure layers and connecting pieces arranged on the upper and lower surfaces of the rock wool layer, a mesh reinforcement structure is formed inside the rock wool layer, greatly improving the tensile strength, dimensional stability, and compressive strength of the rock wool board. However, the inside of the rock wool board is a layered and loose structure. When the mesh structure layer is laterally pushed during handling, it is easy for the connecting pieces to move horizontally inside the rock wool board, resulting in damage to the rock wool board. Utility Model Content

Through the mesh structure layers and connecting pieces arranged on the upper and lower surfaces of the rock wool layer, a mesh reinforcement structure is formed inside the rock wool layer, greatly improving the tensile strength, dimensional stability, and compressive strength of the rock wool board. However, the inside of the rock wool board is a layered and loose structure. When the mesh structure layer is laterally pushed during handling, it is easy for the connecting pieces to move horizontally inside the rock wool board, resulting in damage to the rock wool board.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0017] Optionally, both upper and lower ends of the circular frame are fixedly connected with rubber sealing pads, and the rubber sealing pads are provided with holes matched with the fixing bolts.

[0018] By adopting the above technical solution, the sealing between the return frame and the fixed plate can be improved by the rubber sealing pad to prevent the rock wool layer from contacting with water.

[0019] Optionally, the surfaces of the return frame and the fixing plate are coated with polyurethane waterproof coating.

[0020] By adopting the above technical solution, the waterproof effect of the return frame and the fixed plate can be improved by using the polyurethane waterproof coating.

[0021] Optionally, a plurality of through holes are provided on the upper surface of the connecting strip at equal intervals. A baffle is fixedly connected inside the through holes. Springs are fixedly connected to both side walls of the baffle. One end of the spring away from the baffle is fixedly connected with a clamping block. A part of the clamping block extends out of the through hole.

[0032] The following will further elaborate on this application in conjunction with the Figures 1-5 accompanying drawings.

[0033] Please refer to Figures 1-3 , a heat-insulating rock wool board, including a rock wool layer 1, and a reinforcing component for improving the tensile strength of the rock wool layer 1 is provided on the rock wool layer 1. The reinforcing component includes fixed plates 2 provided on the upper and lower surfaces of the rock wool layer 1. A plurality of vertically arranged steel rods 3 for changing the internal layered loose structure of the rock wool layer 1 and improving the tensile strength are provided inside the rock wool layer 1. Both ends of the steel rod 3 penetrate the rock wool layer 1 and are fixedly connected to the fixed plate 2. A fixing component for improving the stability of the steel rod 3 is provided on the rock wool layer 1. The fixing component includes a U-shaped frame 4 sleeved on the rock wool layer 1. The U-shaped frame 4 is in contact with the rock wool layer 1 to prevent the U-shaped frame 4 from shaking. At the upper and lower ends of one side wall inside the U-shaped frame 4, a plurality of parallel connecting columns 5 for improving the strength of the rock wool layer 1 are fixedly connected. The other end of the connecting column 5 is fixedly connected to the other side wall of the U-shaped frame 4. The connecting column 5 is divided into multiple sections, and a collar 6 for placing the steel rod 3 to move inside the rock wool layer 1 is fixedly connected between each section. The connecting column 5 is located inside the rock wool layer 1, and the steel rods 3 are respectively sleeved in the collars 6.

[0034] During use, through the U-shaped frame 4 sleeved on the rock wool layer 1, the connecting column 5 is located inside the rock wool layer 1, which can prevent the U-shaped frame 4 from shaking. At the same time, the steel rod 3 is sleeved in the collar 6, which can prevent the steel rod 3 from moving in the rock wool layer 1 when the fixed plate 2 is laterally pushed, and squeezing the rock wool layer 1. As much as possible, it avoids the problem that when the reticular structure layer is laterally pushed during the handling process, the connecting piece is likely to move horizontally inside the rock wool board, resulting in damage to the rock wool board.

[0035] Refer to Figure 2 , the length of the steel rod 3 is the same as the thickness of the rock wool layer 1 to prevent the steel rod 3 from being too long and the fixed plate 2 from not being able to fit the rock wool layer 1.

[0036] Refer to Figure 1 and Figure 4 , a plurality of fixed bolts 7 are provided on the fixed plate 2. The fixed bolts 7 all penetrate the fixed plate 2 and are threadedly connected to the U-shaped frame 4. By connecting the fixed plate 2 and the U-shaped frame 4 through the fixed bolts 7, the stability of the fixed plate 2 can be further improved.

[0037] Refer to Figure 4, a plurality of receiving holes 8 are formed in the fixing plate 2, and the fixing bolts 7 are respectively located in the receiving holes 8. Through the receiving holes 8, the fixing bolts 7 can be received to prevent the fixing bolts 7 from partially extending out of the fixing plate 2.

[0038] Referring to Figure 1 , connecting strips 9 are fixedly connected to two adjacent side walls of the U-shaped frame 4, and slots 10 are formed in the other two side walls of the U-shaped frame 4. The slots 10 are engaged with the connecting strips 9. Through the connecting strips 9 and the slots 10, it is convenient to connect the plurality of rock wool layers 1 to each other.

[0039] Referring to Figure 3 , rubber gaskets 11 are fixedly connected to both the upper and lower ends of the U-shaped frame 4. Through holes 12 adapted to the fixing bolts 7 are formed in the rubber gaskets 11. Through the rubber gaskets 11, the sealing performance between the U-shaped frame 4 and the fixing plate 2 can be improved, preventing the rock wool layer 1 from contacting with water.

[0040] Referring to Figure 1 , polyurethane waterproof coatings are applied to the surfaces of both the U-shaped frame 4 and the fixing plate 2. Through the polyurethane waterproof coatings, the waterproof effect of the U-shaped frame 4 and the fixing plate 2 can be improved.

[0041] Referring to Figure 3 and Figure 5 , a plurality of through holes 13 are formed in the upper surface of the connecting strip 9 at equal intervals. A baffle 14 is fixedly connected in the through holes 13. Springs 15 are fixedly connected to both side walls of the baffle 14. One end of the spring 15 far from the baffle 14 is fixedly connected with a latch 16. The latch 16 partially extends out of the through hole 13. Equally spaced locking holes 17 are formed in both the upper and lower side walls of the slot 10. The locking holes 17 are respectively inserted with the latch 16. By pressing the latch 16 to move the latch 16 into the through hole 13, and then inserting the connecting strip 9 into the slot 10, the latch 16 can be snapped into the locking hole 17 by the rebound of the spring 15, improving the connection stability between the connecting strip 9 and the slot 10.

[0042] The implementation principle of this application is as follows: When in use, through the U-shaped frame 4 sleeved on the rock wool layer 1, the connecting column 5 is located inside the rock wool layer 1, which can prevent the U-shaped frame 4 from shaking. At the same time, the steel rod 3 is sleeved in the collar 6, which can prevent the fixing plate 2 from moving in the rock wool layer 1 under lateral pushing, squeezing the rock wool layer 1, and minimizing the problem that when the reticulated structure layer is laterally pushed during handling, the connecting piece is likely to move horizontally in the rock wool board, resulting in damage to the rock wool board.
