Description

Technical Field

[0001] The utility model relates to the technical field of cold-formed thin-walled steel sections, and particularly relates to a cold-formed thin-walled steel section fireproof component. Background Art

[0002] Cold-formed thin-walled steel sections refer to finished steel products with various cross-sectional shapes bent from steel plates or strips in a cold state.

[0003] A patent with the Chinese patent publication number CN220908884U discloses a cold-formed thin-walled steel section fireproof component, which includes a fireproof frame. A flame retardant filling layer is filled inside the fireproof frame. A scraping mechanism is arranged inside the fireproof frame. The scraping mechanism includes a first scraping frame, a second scraping frame, a first guiding slider, a second guiding slider and an adjusting screw rod. The first scraping frame is slidably connected inside the fireproof frame. The second scraping frame is slidably connected inside the fireproof frame. The first guiding slider is fixed at the lower end of the first scraping frame. The second guiding slider is fixed at the lower end of the second scraping frame. The adjusting screw rod is arranged in the adjusting groove of the fireproof frame. Closing end caps are arranged at both ports of the fireproof frame.

[0004] The above patent can solve the corresponding technical problems and facilitate the relatively complete removal of the flame retardant filling layer from the fireproof frame. However, the structure of the above cold-formed thin-walled steel section fireproof component is relatively simple. It only uses a flame retardant filling layer installed inside the fireproof frame, and its compressive capacity is relatively low. It is easily deformed by external collisions during actual use. If the fireproof frame is deformed, it will inevitably cause the fireproof frame to squeeze the scraping frame, thereby affecting the use of the scraping frame, and thus needs to be improved. Summary of the Utility Model

[0006] To achieve the above purpose, the main technical solutions adopted by the utility model include: a cold-formed thin-walled steel section fireproof component, including: a first fireproof frame and a second fireproof frame. A flame retardant filling plate is installed between the inner walls of the first fireproof frame and the second fireproof frame. A sealing frame is installed between the outer walls of the first fireproof frame and the second fireproof frame. Among them, a first strengthening member is arranged between the inner wall of the first fireproof frame and the flame retardant filling plate. A second strengthening member is arranged between the inner wall of the second fireproof frame and the flame retardant filling plate. The first strengthening member and the second strengthening member are connected by a connecting member.

[0007] As a preferred technical solution, the sealing frame is composed of two separately symmetrically arranged U-shaped structural frames, and the two U-shaped structural frames are coated on the connecting edge of the first fireproof frame and the second fireproof frame, and are fixedly connected to the first fireproof frame and the second fireproof frame respectively by rivets.

[0008] As a preferred technical solution, the first reinforcing member includes a first reinforcing frame, and the first reinforcing frame abuts against the inner wall of the first fireproof frame;

[0009] The second reinforcing member includes a second reinforcing frame, and the second reinforcing frame abuts against the inner wall of the second fireproof frame.

[0010] As a preferred technical solution, the connecting member includes a support rod. There are multiple support rods, which are respectively fixedly installed on one side of the first reinforcing frame. Through holes corresponding to the number and position of the support rods are formed on the flame-retardant filling plate, and one end of the support rod passes through the through hole and abuts against one side of the second reinforcing frame.

[0011] As a preferred technical solution, positioning grooves corresponding to the number and position of the support rods are formed on the second reinforcing frame, and one end of the support rod is fitted and abutted inside the positioning groove.

[0012] As a preferred technical solution, clamping grooves are respectively formed on both sides of the flame-retardant filling plate. The first reinforcing frame is fitted and clamped inside the clamping groove on one side, and the second reinforcing frame is fitted and clamped inside the clamping groove on the other side. After clamping, the outer sides of the first reinforcing frame and the second reinforcing frame are respectively flush with the outer side of the flame-retardant filling plate.

[0013] As a preferred technical solution, the flame-retardant filling plate is an expanded perlite board.

[0014] The utility model has at least the following beneficial effects:

[0015] For a cold-formed thin-walled steel fireproof component provided by the utility model, when one side of the first fireproof frame is pressed, the first reinforcing frame abuts against the second reinforcing frame through multiple support rods, which can increase the compressive effect of the first fireproof frame. When one side of the second fireproof frame is pressed, the second reinforcing frame abuts against the second reinforcing frame through multiple support rods, which can increase the compressive effect of the second fireproof frame. Through the combined use of the first reinforcing member, the second reinforcing member and the connecting member, the compressive effect of the whole fireproof component can be increased, deformation is not easy to occur, and the service life of the cold-formed thin-walled steel fireproof component is improved;

[0016] By setting the sealing frame into two U-shaped structural frames, the disassembly and assembly of the sealing frame can be facilitated.

[0025] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0026] Embodiment

[0027] Please refer to Figures 1 to 4As shown in the figure, this embodiment provides a cold-formed thin-walled steel fire protection component, including: a first fire protection frame 1 and a second fire protection frame 2. A flame retardant filling plate 3 is installed between the inner walls of the first fire protection frame 1 and the second fire protection frame 2, and a sealing frame 6 is installed between the outer walls of the first fire protection frame 1 and the second fire protection frame 2. Among them, a first reinforcing member is provided between the inner wall of the first fire protection frame 1 and the flame retardant filling plate 3, a second reinforcing member is provided between the inner wall of the second fire protection frame 2 and the flame retardant filling plate 3, and the first reinforcing member and the second reinforcing member are connected by a connecting member.

[0028] Among them, as Figure 2 shown, the sealing frame 6 is composed of two separately symmetrically arranged U-shaped structural frames, and the two U-shaped structural frames cover the connection edge of the first fire protection frame 1 and the second fire protection frame 2, and are respectively fixedly connected to the first fire protection frame 1 and the second fire protection frame 2 by rivets 7. By setting the sealing frame 6 into two U-shaped structural frames, the disassembly and assembly of the sealing frame 6 can be facilitated. The sealing frame 6 mainly connects, seals and fixes the first fire protection frame 1 and the second fire protection frame 2. The sealing frame 6, the first fire protection frame 1 and the second fire protection frame 2 are all cold-formed thin-walled steel structures. In addition, by covering the flame retardant filling plate 3 outside the first fire protection frame 1 and the second fire protection frame 2, the disassembly and replacement of the flame retardant filling plate 3 can be facilitated.

[0029] Among them, as Figure 3 shown, the first reinforcing member includes a first reinforcing frame 4, and the first reinforcing frame 4 abuts against the inner wall of the first fire protection frame 1; the second reinforcing member includes a second reinforcing frame 5, and the second reinforcing frame 5 abuts against the inner wall of the second fire protection frame 2. The first reinforcing frame 4 can increase the service strength of the first fire protection frame 1, and the second reinforcing frame 5 can increase the service strength of the second fire protection frame 2. By the combined use of the first reinforcing frame 4 and the second reinforcing frame 5, the service strength of the entire fire protection component can be increased, and the first reinforcing frame 4 and the second reinforcing frame 5 can facilitate the pulling out of the flame retardant filling plate 3, further facilitating the disassembly of the flame retardant filling plate 3.

[0030] Among them, as Figure 3 、 Figure 4 shown, the connecting member includes a support rod 401. There are multiple support rods 401, and they are respectively fixedly installed on one side of the first reinforcing frame 4. The flame retardant filling plate 3 is provided with through holes 301 corresponding to the number and position of the support rods 401. One end of the support rod 401 passes through the through hole 301 and abuts against one side of the second reinforcing frame 5. The function of the support rod 401 is to support between the first reinforcing frame 4 and the second reinforcing frame 5, further increasing the installation stability of the first fire protection frame 1 and the second fire protection frame 2, increasing the compressive strength, improving the service life, and being able to further protect the flame retardant filling plate 3 to ensure the overall integrity of the flame retardant filling plate 3.

[0031] Among them, as Figure 3 、 Figure 4As shown in the figure, the second reinforcing frame 5 is provided with positioning grooves 501 corresponding to the number and positions of the support rods 401. One end of each support rod 401 is fitted and abutted inside the positioning groove 501. By fitting and abutting one end of the support rod 401 inside the positioning groove 501, the first fireproof frame 1 and the second fireproof frame 2 can be quickly and closedly installed. At the same time, the positioning groove 501 can also limit the support rod 401, further increasing the installation stability of the first fireproof frame 1 and the second fireproof frame 2.

[0032] Among them, as Figure 3 shown, clamping grooves 302 are respectively formed on both sides of the flame-retardant filling plate 3. The first reinforcing frame 4 is fitted and clamped inside the clamping groove 302 on one side, and the second reinforcing frame 5 is fitted and clamped inside the clamping groove 302 on the other side. The outer sides of the first reinforcing frame 4 and the second reinforcing frame 5 after clamping are respectively flush with the outer side of the flame-retardant filling plate 3. By clamping the first reinforcing frame 4 and the second reinforcing frame 5 inside the clamping grooves 302 on both sides of the flame-retardant filling plate 3 respectively, and the outer sides are respectively flush with the outer side of the flame-retardant filling plate 3, the flame-retardant filling plate 3 can be made to fit the inner walls of the first fireproof frame 1 and the second fireproof frame 2, increasing the use effect of the fireproof component.

[0033] Among them, the flame-retardant filling plate 3 is an expanded perlite board, which has the characteristics of light weight, heat preservation, fire prevention, moisture proof, non-deformation modification, and non-rot decay and mildew, which is helpful for the use of this fireproof component, further increasing the use effect of this cold-formed thin-walled steel fireproof component.

[0034] Working principle: When one side of the first fireproof frame 1 is pressed, the first reinforcing frame 4 abuts against the second reinforcing frame 5 through a plurality of support rods 401, which can increase the compressive effect of the first fireproof frame 1. When one side of the second fireproof frame 2 is pressed, the second reinforcing frame 5 abuts against the second reinforcing frame 5 through a plurality of support rods 401, which can increase the compressive effect of the second fireproof frame 2. Through the combined use of the first reinforcing frame 4, the second reinforcing frame 5 and a plurality of support rods 401, the compressive effect of the entire protection component can be increased, and deformation is not likely to occur;

[0035] When the flame-retardant filling plate 3 needs to be removed and replaced, first remove the sealing frame 6 fixedly connected to the first fireproof frame 1 and the second fireproof frame 2, and then forcefully separate the first fireproof frame 1 and the second fireproof frame 2 outward to complete the disassembly of the flame-retardant filling plate 3. If the flame-retardant filling plate 3 is adhered to the inner walls of the first fireproof frame 1 and the second fireproof frame 2 and is not easy to separate, the first reinforcing frame 4 and the second reinforcing frame 5 can be respectively pried by using a lever. The prying of the first reinforcing frame 4 and the second reinforcing frame 5 can drive the flame-retardant filling plate 3 to be pried, so that the flame-retardant filling plate 3 is separated from the inner walls of the first fireproof frame 1 and the second fireproof frame 2, and the disassembly of the flame-retardant filling plate 3 can be facilitated.

[0036] The foregoing description has shown and described several preferred embodiments of the present utility model. However, as previously mentioned, it should be understood that the present utility model is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the above teachings or the techniques or knowledge in related fields. Any alterations and changes made by those skilled in the art that do not depart from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
