[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion; generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance.
[0003] Although existing high-temperature resistant flame-retardant fireproof boards for steel structures are made of fireproof materials and can effectively retard and prevent fire, the connection strength between the internal layers of the fireproof board is not high, resulting in an unstable structure. Utility Model Content

[0005] This application provides a high-temperature resistant, flame-retardant fireproof board for steel structures, comprising a first fireproof board and a second fireproof board; both the first and second fireproof boards have an intermediate layer; the outer wall of the intermediate layer is provided with a fireproof adhesive layer, and the intermediate layer is connected to an outer layer through the fireproof adhesive layer, wherein there are two outer layers symmetrically distributed; a reinforcing plate is provided on the outer side of the intermediate and outer layers, and a first bolt is threadedly connected to the inner thread of the reinforcing plate and the outer layer, and a second bolt is threadedly connected to the inner thread of the reinforcing plate and the intermediate layer; threaded holes matching the first and second bolts are provided on the outer layer, the intermediate layer, and the reinforcing plate.
[0006] Preferably, the outer wall of one of the outer layers is provided with a fire-retardant coating layer, and the outer wall of the other outer layer is bonded to the steel structure with fire-retardant adhesive.
[0007] Preferably, the reinforcing plate has a first mounting groove on the side near the first bolt and the second bolt.

[0009] Preferably, the insert plate is internally threadedly connected to the intermediate layer plate and the outer layer plate by a third bolt.
[0010] Preferably, the insert plate has a first threaded hole inside, and the intermediate layer plate and the outer layer plate have a second threaded hole inside, and the first threaded hole and the second threaded hole are matched with the third bolt.
[0011] Preferably, the outer layer plate has a second mounting groove near the third bolt.
[0012] Beneficial effects:
[0013] Considering that the existing high-temperature resistant flame-retardant fireproof boards for steel structures are made of fireproof materials and can effectively retard and prevent fire, the connection strength between the internal layers of the fireproof board is not high, resulting in the problem that the fireproof board itself is not solid.
[0014] This application first bonds two outer layers to the outer wall of the middle layer using a fire-retardant adhesive layer. Then, a reinforcing plate is attached to the outer sides of the outer and middle layers. A first bolt is screwed into the threaded holes on the outer and reinforcing plates to secure the outer layers to the reinforcing plate. A second bolt is screwed into the threaded holes on the middle and reinforcing plates to secure the middle layer to the reinforcing plate, thereby increasing the preload between the middle and outer layers and making the high-temperature resistant, flame-retardant fireproof board structure for steel structures more robust.

[0029] This utility model provides, for example Figure 1-4 The fireproof steel structure high-temperature resistant flame-retardant board shown includes a first fireproof board 1 and a second fireproof board 2; both the first fireproof board 1 and the second fireproof board 2 have an intermediate layer 3 inside; the outer wall of the intermediate layer 3 is provided with a fireproof adhesive layer 4, and the intermediate layer 3 is connected to an outer layer 5 through the fireproof adhesive layer 4. There are two outer layer 5s, which are symmetrically distributed; a reinforcing plate 7 is provided on the outer side of the intermediate layer 3 and the outer layer 5. The reinforcing plate 7 is internally threaded to the outer layer 5 with a first bolt 9, and the reinforcing plate 7 is internally threaded to the intermediate layer 3 with a second bolt 10. The outer layer 5, the intermediate layer 3, and the reinforcing plate 7 have threaded holes that match the first bolt 9 and the second bolt 10.
[0030] First, the two outer layers 5 are bonded to the outer wall of the middle layer 3 using the fireproof adhesive layer 4. Then, the reinforcing plate 7 is attached to the outer sides of the outer layers 5 and the middle layer 3. The first bolt 9 is screwed into the threaded holes on the outer layers 5 and the reinforcing plate 7 to fix the outer layers 5 and the reinforcing plate 7. The second bolt 10 is screwed into the threaded holes on the middle layer 3 and the reinforcing plate 7 to fix the middle layer 3 and the reinforcing plate 7, thereby increasing the preload between the middle layer 3 and the outer layers 5, making the high-temperature resistant flame-retardant fireproof board structure for steel structures more robust.
[0031] One outer panel 5 has a fire-retardant coating layer 6 on its outer wall, and the other outer panel 5 is bonded to the steel structure with fire-retardant adhesive.
[0032] One of the outer panels 5 is connected to the steel structure with fire-retardant adhesive, and the other outer panel 5 is coated with a fire-retardant coating layer 6. The material of the fire-retardant coating layer 6 is fire-retardant paint, which has a fire-retardant effect.
[0033] The reinforcing plate 7 has a first mounting groove 8 on the side near the first bolt 9 and the second bolt 10.
[0034] Among them, the first bolt 9 and the second bolt 10 can be screwed into the first mounting groove 8, making the outer wall of the reinforcing plate 7 more aesthetically pleasing.
[0035] The outer wall of the reinforcing plate 7 is fixedly connected with an insert plate 11, and the middle layer plate 3 has a slot 13 on the side away from the insert plate 11, and the insert plate 11 matches the slot 13.
[0036] The insert plate 11 on the first fireproof plate 1 can be inserted into the slot 13 on the second fireproof plate 2, so that the first fireproof plate 1 and the second fireproof plate 2 are connected together.
[0037] The insert plate 11 is internally threadedly connected to the intermediate layer plate 3 and the outer layer plate 5 by a third bolt 16.
[0038] The third bolt 16 can securely connect the intermediate layer plate 3 and the insert plate 11 together.
[0039] The insert plate 11 has a first threaded hole 12 inside, and the middle layer plate 3 and the outer layer plate 5 have a second threaded hole 15 inside. The first threaded hole 12 and the second threaded hole 15 are matched with the third bolt 16.

[0043] Working principle: When using this high-temperature resistant, flame-retardant fireproof board for steel structures, firstly, the two outer layers 5 are bonded to the outer wall of the middle layer 3 through the fireproof adhesive layer 4. Then, the reinforcing plate 7 is attached to the outer side of the outer layers 5 and the middle layer 3. The first bolt 9 is screwed into the threaded holes on the outer layers 5 and the reinforcing plate 7 to fix the outer layers 5 and the reinforcing plate 7. The second bolt 10 is screwed into the threaded holes on the middle layer 3 and the reinforcing plate 7 to fix the middle layer 3 and the reinforcing plate 7, thereby increasing the preload between the middle layer 3 and the outer layers 5, making the structure of this high-temperature resistant, flame-retardant fireproof board for steel structures more robust.
[0044] Furthermore, the outer layer 5 is made of magnesium oxide board or basalt fiberboard, while the middle layer 3 is made of cementitious material. The combination of the outer layer 5 and the middle layer 3, along with the fire-retardant adhesive layer 4 and the fire-retardant coating layer 6, allows this high-temperature resistant, flame-retardant fireproof board structure for steel structures to possess excellent high-temperature resistance, flame retardant, and fireproof properties.
[0045] Furthermore, the insert plate 11 on the first fireproof board 1 can be inserted into the slot 13 on the second fireproof board 2. Then, the third bolt 16 is screwed into the insert plate 11 and the intermediate layer plate 3 through the first threaded hole 12 and the second threaded hole 15, so that the first fireproof board 1 and the second fireproof board 2 are firmly connected together, realizing the splicing function of this high-temperature resistant flame-retardant fireproof board for steel structures.
