Description

Technical Field

[0001] This invention relates to the field of rock wool board technology, specifically to a pre-cut rock wool board. Background Technology

[0002] To ensure the accuracy of installation, construction efficiency, and overall performance of the insulation system, some rock wool boards are pre-cut to avoid material waste and poor joints caused by arbitrary on-site cutting.

[0003] Currently, most pre-cut rock wool boards on the market have pre-cut grooves. These grooves reduce the overall strength of the rock wool board. Although they do not affect the installation of the rock wool board, they are very easy to break during transportation, causing one rock wool board to break into multiple rock wool blocks, thus affecting the installation efficiency of the rock wool board. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pre-cut rock wool board, primarily to solve the problem that rock wool boards are very prone to breakage during transportation, resulting in one rock wool board becoming multiple rock wool blocks, thus affecting the installation efficiency of the rock wool board.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A pre-cut rock wool board includes a board body, a reinforcing plate at the top of the board body, and multiple transverse pre-cut grooves and multiple longitudinal pre-cut grooves extending through the top of both the reinforcing plate and the board body. The board body and the reinforcing plate are fixed together by a locking mechanism. First connecting components that reinforce and detach the transverse and longitudinal pre-cut grooves on both sides of the board body are provided. Second connecting components that reinforce and detach the transverse and longitudinal pre-cut grooves on both sides of the reinforcing plate are provided.

[0006] Furthermore, the locking mechanism includes multiple threaded cylinders fixed to the bottom of the reinforcing plate. The top of the plate has a through hole, and the threaded cylinders are threadedly connected to the fixing screws through the through hole. The bottom of the plate has a second clearance groove that communicates with the through hole, and the bottom of the fixing screw does not extend beyond the second clearance groove.

[0007] Based on the aforementioned solution, the first connecting component includes a plurality of first clearance grooves opened at the bottom of the plate. Each end of the top inner wall of the first clearance groove is provided with a slot, and a bracket is inserted into the slot. The bracket is U-shaped and the bottom of the bracket does not exceed the first clearance groove. The top of the bracket is provided with a limiting component for auxiliary fixing of the bracket.

[0008] As a further embodiment of the present invention, the limiting component includes elastic plates integrally formed at both ends of the top of the insert, a guide frame integrally formed at the bottom of the reinforcing plate, an arc-shaped groove opened at the top of the slot, and the guide frame inserted into the arc-shaped groove, and the guide frame in contact with the elastic plate.

[0009] Furthermore, a notch is provided on one side of the elastic plate, and a barb plate is integrally formed with the elastic plate inside the notch. A through hole is provided at the bottom of the insert, and a third clearance groove is provided at the top of the through hole.

[0010] Based on the aforementioned solution, the second connecting component includes a slot formed on the top of the reinforcing plate, at least one groove is formed on one side of the slot, and a block is inserted into the slots on two opposite sides. At least one protrusion is integrally formed on the opposite side of the block, and the protrusion can be inserted into the groove.

[0011] As a further embodiment of the present invention, the top of the reinforcing plate is bonded with an upper paper surface, the bottom of the plate body is bonded with a lower paper surface, and the bottom of the plate body and the reinforcing plate are provided with mounting holes.

[0012] Compared with the prior art, the present invention provides a pre-cut rock wool board, which has the following beneficial effects: 1. This invention strengthens the connection between the cut section and the connection point of the rock wool board by using a reinforcing plate in conjunction with the first connecting component and the second connecting component, making it less likely to break at the cut point. Furthermore, the first connecting component and the second connecting component can be removed during use, allowing for normal and rapid segmentation and improving the strength of the rock wool board during transportation.

[0013] 2. The present invention has a locking mechanism. The threaded cylinder passes through the insertion hole and the fixing screw is screwed into the threaded cylinder, so that the plate is clamped and fixed by the fixing screw and the reinforcing plate, thus completing the connection between the plate and the reinforcing plate. Each rock wool block is fixed by the threaded cylinder and the fixing screw, so that each rock wool block can have a reinforcing plate, thereby improving the strength of each rock wool block.

[0014] 3. The present invention provides a first connecting component, in which the insert connects the rock wool blocks on both sides of the pre-cut groove, thereby strengthening and fixing the bottom of the rock wool board, so that it will not break due to the force on the bottom during transportation, and improving the strength of the rock wool board during transportation after pre-cutting.

[0015] 4. By providing a limiting component, the bending elastic plate increases the friction between itself and the arc-shaped groove, thus assisting in fixing the insert and preventing it from easily moving out of the slot, thereby improving the stability of the insert installation.

[0016] 5. The present invention provides a hook plate that hooks onto the guide frame, thereby increasing the friction between the hook plate and the guide frame, making it more difficult for the elastic plate to move out of the guide groove, and further increasing the stability of the bracket installation.

[0017] 6. The present invention provides a second connecting component, in which the card block is inserted into two opposite card slots, thereby strengthening both sides of the pre-cut groove. When the card block is inserted into the card slot, the protrusion will be inserted into the groove to assist in fixing the card block, thereby improving the overall strength of the reinforcing plate after pre-cutting.

[0023] Please see Figures 1-7 As shown, a pre-cut rock wool board includes a board body 1, which is a rock wool board. A reinforcing plate 2 is provided on the top of the board body 1. The reinforcing plate 2 is made of polyphenylene sulfide and has excellent high temperature resistance, corrosion resistance, flame retardancy and mechanical properties. Multiple transverse pre-cut grooves 4 and multiple longitudinal pre-cut grooves 3 are provided through the top of both the reinforcing plate 2 and the board body 1. The board body 1 and the reinforcing plate 2 are fixed together by a locking mechanism. A first connecting component is provided on both sides of the transverse pre-cut grooves 4 and the longitudinal pre-cut grooves 3 on the board body 1 for reinforcing connection and detachable connection. A second connecting component is provided on both sides of the transverse pre-cut grooves 4 and the longitudinal pre-cut grooves 3 on the reinforcing plate 2 for reinforcing connection and detachable connection. The pre-cut rock wool board is reinforced by the reinforcing plate 2 to enhance the strength of the connection points. The pre-cut section of the board 1 is connected by the first connecting component, which enhances the overall strength of the cut board 1. The pre-cut section of the reinforcing plate 2 is connected by the second connecting component, which enhances the overall strength of the cut reinforcing plate 2. The cut section of the rock wool board and the connection point after cutting are reinforced to make it less likely to break at the cut point. Furthermore, the first and second connecting components can be removed during use, allowing for normal and rapid segmentation and improving the strength of the rock wool board during transportation.

[0024] In this invention, the locking mechanism includes a plurality of threaded cylinders 15 fixed to the bottom of the reinforcing plate 2, an insertion hole 20 is provided through the top of the plate body 1, and the threaded cylinders 15 are threadedly connected to the fixing screws 8 through the insertion hole 20. A second clearance groove 7 communicating with the insertion hole 20 is provided at the bottom of the plate body 1, and the bottom end of the fixing screw 8 does not exceed the second clearance groove 7. When connecting the reinforcing plate 2 to the plate body 1, first apply glue to the connection between the reinforcing plate 2 and the plate body 1, then pass the threaded cylinder 15 through the insertion hole 20, and use the fixing screw 8 to screw into the threaded cylinder 15, so that the plate body 1 is clamped and fixed by the fixing screw 8 and the reinforcing plate 2, thereby completing the connection between the plate body 1 and the reinforcing plate 2, and each rock wool block will be fixed by the threaded cylinder 15 and the fixing screw 8, so that each rock wool block can have the reinforcing plate 2, thereby improving the strength of each rock wool block.

[0025] The first connecting component includes a plurality of first clearance grooves 5 opened at the bottom of the plate 1. Each end of the top inner wall of the first clearance groove 5 is provided with a slot 19. A bracket 6 is inserted into the slot 19. The bracket 6 is U-shaped and the bottom of the bracket 6 does not exceed the first clearance groove 5. The bracket 6 is made of aluminum alloy. The top of the bracket 6 is provided with a limiting component for auxiliary fixing of the bracket 6. After the pre-cut groove is cut in the reinforcing plate 2, the insert 6 is inserted into the slot 19 and the limiting component is used to fix the insert 6, so that the insert 6 connects the rock wool blocks on both sides of the pre-cut groove, thereby strengthening and fixing the bottom of the rock wool board, so that it will not break due to the force on the bottom during transportation, and improving the strength of the rock wool board during transportation after pre-cutting.

[0026] Furthermore, the limiting component includes elastic plates 21 integrally formed at both ends of the top of the insert 6, a guide frame 16 integrally formed at the bottom of the reinforcing plate 2, an arc-shaped groove 18 opened at the top of the slot 19, and the guide frame 16 is inserted into the arc-shaped groove 18, and the guide frame 16 is in contact with the elastic plate 21. After the reinforcing plate 2 is fixed to the plate body 1, the guide frame 16 will be inserted into the arc-shaped groove 18. An arc-shaped guide groove is formed between the guide frame 16 and the arc-shaped groove 18. When the insert 6 is inserted into the slot 19, the guide groove will squeeze the elastic plate 21 to bend. The bent elastic plate 21 will increase the friction between it and the arc-shaped groove 18, thereby assisting in fixing the insert 6 and preventing the insert 6 from easily moving out of the slot 19, thus improving the stability of the insert 6 installation.

[0027] Furthermore, a notch 22 is provided on one side of the elastic plate 21, and a barb plate 23 is integrally formed with the elastic plate 21 inside the notch 22. A through hole 24 is provided at the bottom of the insert 6, and a third clearance groove 25 is provided at the top of the through hole 24. The barbed plate 23, which is not in contact with the elastic plate 21 at one end, will hook onto the guide frame 16 under the reaction force of bending, thereby increasing the friction between the barbed plate 23 and the guide frame 16, making it more difficult for the elastic plate 21 to move out of the guide groove, and further increasing the stability of the installation of the insert 6. When it is necessary to disassemble the insert 6, use an I-shaped tool to pass through the through hole 24, and then rotate the tool so that one end of the tool enters the third clearance groove 25, so that the insert 6 can be directly pulled out of the slot 19.

[0028] Furthermore, the second connecting component includes a slot 13 formed on the top of the reinforcing plate 2. At least one groove 14 is formed on one side of the slot 13. A block 11 is inserted into the slots 13 on the two opposite sides. The block 11 is also made of polyphenylene sulfide. At least one protrusion 17 is integrally formed on the opposite side of the block 11, and the protrusion 17 can be inserted into the groove 14. After the pre-cut groove is opened on the reinforcing plate 2, the locking block 11 is inserted into the two opposite locking slots 13, thereby reinforcing both sides of the pre-cut groove. When the locking block 11 is inserted into the locking slot 13, the protrusion 17 will be inserted into the groove 14 to assist in fixing the locking block 11. When the locking block 11 needs to be disassembled, simply use a thin plate to push the locking block 11 upward from the pre-cut groove to push the locking block 11 out of the locking slot 13. This improves the overall strength of the reinforcing plate 2 after pre-cutting and also improves the convenience of dividing the reinforcing plate 2 into sections.

[0029] Furthermore, the top of the reinforcing plate 2 is bonded with an upper paper surface 10, and the bottom of the plate body 1 is bonded with a lower paper surface 12. The upper paper surface 10 and the lower paper surface 12 allow external putty and other materials to adhere to the rock wool board. The bottom of the plate body 1 and the reinforcing plate 2 are provided with mounting holes 9, which can be directly installed by passing expansion screws through the mounting holes 9.

[0030] The present invention is used in the following steps: S1: When producing rock wool board, firstly, a transverse pre-shearing groove 4 and a longitudinal pre-shearing groove 3 are opened on the board body 1. After the opening is completed, glue is applied to the connection between the reinforcing plate 2 and the board body 1. Then, the threaded cylinder 15 is passed through the insertion hole 20, and the fixing screw 8 is screwed into the threaded cylinder 15, so that the board body 1 is clamped and fixed by the fixing screw 8 and the reinforcing plate 2, thereby completing the connection between the board body 1 and the reinforcing plate 2. S2: When the insert 6 is inserted into the slot 19, the guide groove will squeeze the elastic plate 21 and bend it. The barb plate 23, which is not in contact with the elastic plate 21 at one end, will hook the guide frame 16 under the reaction force of bending. The bent elastic plate 21 will increase the friction between it and the arc groove 18. The barb plate 23 hooks the guide frame 16, increasing the friction between the barb plate 23 and the guide frame 16, so that the insert 6 will not easily move out of the slot 19. S3: Insert the card block 11 into the two opposite card slots 13 to strengthen both sides of the pre-cut groove. When the card block 11 is inserted into the card slot 13, the protrusion 17 will be inserted into the groove 14 to assist in fixing the card block 11. S4: When it is necessary to divide the rock wool board into blocks, use an I-shaped tool to pass through the perforation 24, and then rotate the tool so that one end of the tool enters the third relief groove 25, thereby directly pulling the insert 6 out of the slot 19, removing the reinforcement of the pre-shear groove opened on the board body 1, so that it can be easily broken. S5: By using a thin plate to push the locking block 11 upward from the pre-shear groove, the locking block 11 can be pushed out from the slot 13, thereby releasing the reinforcement of the pre-shear groove opened on the reinforcing plate 2, making it easy to break, and thus improving the convenience of on-site construction of rock wool board.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
