Description

Technical Field

[0001] The utility model belongs to the field of fireproof rock wool sandwich panels, and specifically relates to a fireproof rock wool sandwich panel. Background Technique

[0002] The rock wool sandwich panel is a sandwich panel made of rock wool as raw material. The rock wool sandwich panel gives full play to the unique properties of the rock wool core material and has remarkable effects in aspects such as fire prevention, heat insulation, sound absorption and sound insulation.

[0003] The existing authorized announcement is CN206520278U, which discloses a rock wool sandwich panel, including a housing. Metal plates are symmetrically arranged on both sides of the housing. Heat insulation plates are arranged on one side of each of the two metal plates. Fixing plates are fixedly connected inside each of the two heat insulation plates. A telescopic rod is arranged between the two fixing plates. A first spring is sleeved outside the telescopic rod, and two ends of the first spring are respectively connected to the upper end and the lower end of the two fixing plates. A plurality of reinforcing members are arranged between the two heat insulation plates. Rock wool is filled in the gap between the two heat insulation plates. One end of the housing is fixedly connected with a first fixing block. Locking grooves are symmetrically arranged on both sides of the upper and lower ends of the first fixing block. One end of the first fixing block away from the housing is fixedly connected with a second fixing block. A plurality of limiting blocks are symmetrically arranged on both sides of the second fixing block.

[0004] In the above technology, by filling rock wool in the gap between the two heat insulation plates, the sandwich panel has certain fire prevention performance. However, when the surface of the sandwich panel is damaged to a certain extent, its fire prevention performance is reduced, thereby reducing the use safety. At the same time, by setting the first fixing block and the second fixing block, adjacent sandwich panels can be spliced, ensuring the stability of their connection. However, only using the connection of the first fixing block and the second fixing block, the joint is easily deformed under external force and finally breaks, thereby reducing its service life. In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0005] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a fireproof rock wool sandwich panel.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present utility model is:

[0007] A fireproof rock wool sandwich panel includes a main steel plate, auxiliary high-temperature resistant plates, a first fireproof rock wool sandwich layer and a second fireproof rock wool sandwich layer. Auxiliary high-temperature resistant plates are attached to both the upper and lower ends of the main steel plate. L-shaped blocks are fixed on both sides of the auxiliary high-temperature resistant plates and the main steel plate. The connected L-shaped blocks on each side are fixed by U-shaped fixing bars.

[0008] A cavity for placing the first fireproof rock wool sandwich layer and the second fireproof rock wool sandwich layer is provided in the middle of each of the two auxiliary high-temperature resistant plates and the main steel plate. A plurality of first fixing clamps and second fixing clamps are respectively fixed on both sides of the two auxiliary high-temperature resistant plates and the main steel plate. An upper clamp block, a middle clamp block and a lower clamp block are respectively fixed by screws in the middle of the plurality of first fixing clamps on one side, and a first special-shaped clamping block and a second special-shaped clamping block are respectively fixed by screws in the middle of the plurality of second fixing clamps on the other side;

[0009] Splicing card slots adapted to the outer contours of the first special-shaped clamping block and the second special-shaped clamping block are respectively provided on the opposite surfaces of the plurality of upper clamp blocks, middle clamp blocks and lower clamp blocks. The upper clamp block, the middle clamp block, the lower clamp block, the first special-shaped clamping block and the second special-shaped clamping block are fixed by a fixing bolt in cooperation with a fixing nut.

[0010] Optionally, an anti-rust protection cover is sleeved on both the screwing end and the bottom of the fixing bolt.

[0011] Optionally, a plurality of screw holes for the fixing bolt to be screwed into penetrate through the middle parts of the upper clamp block, the middle clamp block, the lower clamp block, the first special-shaped clamping block and the second special-shaped clamping block.

[0012] Optionally, a plurality of reinforcing columns are equidistantly fixed in the middle of the auxiliary high-temperature resistant plate. The reinforcing columns are vertically arranged inside the auxiliary high-temperature resistant plate, and a plurality of positioning columns are fixed inside the auxiliary high-temperature resistant plate. The positioning columns penetrate and are connected inside the second fireproof rock wool sandwich layer, and the second fireproof rock wool sandwich layer is horizontally arranged inside the auxiliary high-temperature resistant plate.

[0013] Optionally, inclined support rods are fixed at the four corners inside the main steel plate. A reinforcing area for placing a reinforcing wedge block is provided between each inclined support rod and the cavity, and the reinforcing wedge block abuts against the inner wall of the reinforcing area.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below:

[0015] The utility model improves the durability of the device through the auxiliary high-temperature resistant plates attached to the outer surfaces on both sides of the main steel plate. Even when wear occurs, it is necessary to wear the auxiliary high-temperature resistant plates first before the main steel plate can be damaged and its functionality affected. Moreover, the fire resistance performance of the device is improved. Cavities for placing the first fireproof rock wool sandwich layer and the second fireproof rock wool sandwich layer are provided inside both the main steel plate and the auxiliary high-temperature resistant plate. Therefore, multi-layer fire protection can be achieved using multiple layers of fireproof rock wool. Even after a single layer is damaged, the fireproof effect can still be maintained. Secondly, to avoid the problem in the prior art that the joint is easily deformed under external pressure and finally breaks, thereby reducing its service life, in the utility model, a plurality of inclined struts are arranged at the four corners inside the main steel plate, making the reinforcement area a stable triangular structure. Therefore, the stability of the splicing part is enhanced and deformation will not occur. Secondly, to ensure the stability of the splicing parts of multiple devices, a plurality of fixing bolts and fixing nuts are used to reinforce the splicing parts of the upper clamping block, middle clamping block, lower clamping block, first special-shaped block and second special-shaped block. That is, two devices can complete the splicing process of multiple devices by inserting the first special-shaped block and the second special-shaped block on their sides into the splicing card slots of the upper clamping block, middle clamping block and lower clamping block. After splicing, a plurality of fixing bolts are screwed in and then the fixing nuts are tightened.

Detailed implementation mode

[0028] Now, the present utility model will be further described in detail with reference to the attached drawings.

[0029] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a fireproof rock wool sandwich panel, including a main steel plate 1, an auxiliary high-temperature resistant plate 2, a first fireproof rock wool sandwich layer 5 and a second fireproof rock wool sandwich layer 6. The upper and lower ends of the main steel plate 1 are both attached with the auxiliary high-temperature resistant plate 2. L-shaped blocks 3 are fixed on both sides of the auxiliary high-temperature resistant plate 2 and the main steel plate 1, and the connected L-shaped blocks 3 on each side are fixed by a C-shaped fixing strip 4;

[0030] Cavities for placing the first fireproof rock wool sandwich layer 5 and the second fireproof rock wool sandwich layer 6 are opened in the middle parts of the two auxiliary high-temperature resistant plates 2 and the main steel plate 1. A plurality of first fixing clamps 7 and second fixing clamps 8 are respectively fixed on both sides of the two auxiliary high-temperature resistant plates 2 and the main steel plate 1. An upper clamping block 9, a middle clamping block 10 and a lower clamping block 11 are respectively fixed in the middle parts of the plurality of first fixing clamps 7 on one side by screws, and a first special-shaped clamping block 12 and a second special-shaped clamping block 13 are respectively fixed in the middle parts of the plurality of second fixing clamps 8 on the other side by screws;

[0031] The opposite surfaces of multiple upper clamping blocks 9, middle clamping blocks 10 and lower clamping blocks 11 are respectively provided with splicing clamping grooves 14 adapted to the outer contours of the first special-shaped clamping block 12 and the second special-shaped clamping block 13. The upper clamping block 9, middle clamping block 10, lower clamping block 11, first special-shaped clamping block 12 and second special-shaped clamping block 13 are fixed by the cooperation of fixing bolts 15 and fixing nuts 16. Considering that in the prior art, rock wool is filled in the gap between two heat insulation boards, so that the sandwich panel has a certain fireproof performance. However, when the surface of the sandwich panel is damaged to a certain extent, its fireproof performance is reduced, thus reducing the use safety. At the same time, by setting the first fixing block and the second fixing block, adjacent sandwich panels can be spliced, ensuring the stability of their connection. However, only using the connection of the first fixing block and the second fixing block, the joint is easily deformed under external force compression and finally breaks, thus reducing its service life. The utility model improves the durability of the device through the auxiliary high-temperature resistant board 2 attached to the outer surfaces on both sides of the main steel plate 1. Even when wear occurs, it is necessary to wear the auxiliary high-temperature resistant board 2 first to damage the main steel plate 1 and affect its functionality, and improve the fireproof performance of the device. Cavities for placing the first fireproof rock wool sandwich layer 5 and the second fireproof rock wool sandwich layer 6 are arranged inside the main steel plate 1 and the auxiliary high-temperature resistant board. Therefore, multiple layers of fireproof rock wool can be used for multiple layers of fireproof protection. Even if a single layer is damaged, the fireproof effect can still be maintained. Secondly, in order to avoid the problem that in the prior art, the joint is easily deformed under external force compression and finally breaks, thus reducing its service life, the utility model makes the reinforcement area a stable triangular structure through multiple inclined struts 21 arranged at the four corners inside the main steel plate 1. Therefore, the stability of the splicing part is strengthened and no deformation will occur. Secondly, in order to ensure the stability of the splicing parts of multiple devices, the splicing parts of the upper clamping block 9, middle clamping block 10, lower clamping block 11, first special-shaped clamping block 12 and second special-shaped clamping block 13 will be reinforced by multiple fixing bolts 15 and fixing nuts 16. That is, two devices can complete the splicing process of multiple devices after the first special-shaped clamping block 12 and the second special-shaped clamping block 13 on their sides are inserted into the splicing clamping grooves 14 of the upper clamping block 9, middle clamping block 10 and lower clamping block 11. After splicing, multiple fixing bolts 15 are screwed in and then the fixing nuts are tightened.

[0032] Wherein, anti-rust protection covers 17 are sleeved on both the screwing end and the bottom of the fixing bolt 15. By setting the anti-rust protection block, it plays a protective role for both the screwing end and the bottom of the fixing bolt 15, effectively preventing rainwater from seeping in and causing the fixing bolt 15 to rust, resulting in inconvenient disassembly. After the device is spliced and installed, the anti-rust protection cover 17 will be sleeved on the screwing end and the bottom of the fixing bolt 15, so that the anti-rust protection cover 17 can cover the gaps at the bottom and the end of the fixing bolt 15, preventing rainwater from seeping in.

[0033] Among them, the upper clamping block 9, the middle clamping block 10, the lower clamping block 11, the first special-shaped clamping block 12 and the second special-shaped clamping block 13 are all penetrated with a plurality of screw holes 18 for the fixing bolts 15 to be screwed into in the middle. By setting the screw holes 18, it is convenient for the user to screw in the fixing bolts 15 to reinforce the upper clamping block 9, the middle clamping block 10, the lower clamping block 11, the first special-shaped clamping block 12 and the second special-shaped clamping block 13 spliced together, thereby improving the fastening degree after the splicing of multiple devices.

[0034] Among them, a plurality of reinforcing columns 19 are fixedly arranged at equal intervals in the middle of the auxiliary high-temperature-resistant plate 2. The reinforcing columns 19 are arranged vertically inside the auxiliary high-temperature-resistant plate 2, and a plurality of positioning columns 20 are fixedly arranged inside the auxiliary high-temperature-resistant plate 2. The positioning columns 20 penetrate and are connected inside the second fireproof rock wool sandwich layer 6, and the second fireproof rock wool sandwich layer 6 is arranged horizontally inside the auxiliary high-temperature-resistant plate 2. By setting a plurality of reinforcing columns 19, the auxiliary high-temperature-resistant plate is reinforced, preventing the auxiliary high-temperature-resistant plate 2 from deforming after being subjected to a lateral impact, thereby damaging the second fireproof rock wool sandwich layer 6 inside it. By using a plurality of positioning columns 20, the pressure resistance of the auxiliary high-temperature-resistant plate 2 is improved, and the auxiliary high-temperature-resistant plate 2 can be supported.

[0035] Among them, inclined struts 21 are fixedly arranged at the four corners inside the main steel plate 1. There is a reinforcing area for placing the reinforcing wedge blocks 22 between each inclined strut 21 and the cavity, and the reinforcing wedge blocks 22 are in contact with the inner wall of the reinforcing area. By setting the inclined struts 21, while reinforcing the cavity inside the main steel plate 1, the side part of the main steel plate 1 can also be supported, ensuring the stability of the side part of the main steel plate 1.

[0036] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
