Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically a fireproof and high-temperature resistant steel structure. Background Technology

[0002] Fire-resistant and high-temperature resistant steel structures are building structures with both fire-resistant and high-temperature resistant properties. Due to their excellent fire resistance, they reduce reliance on external fire protection measures, lowering construction costs and complexity. Furthermore, the mechanical and processing properties of fire-resistant steel are similar to ordinary steel, facilitating processing and installation in engineering projects. They are widely used in construction, bridges, and other engineering fields with high fire resistance requirements. Fire-resistant steel is a low-alloy steel made by adding alloying elements such as molybdenum.

[0027] Combination Figures 1-4 A fire-resistant and high-temperature resistant steel structure includes a fire-resistant and high-temperature resistant steel plate 1. The fire-resistant and high-temperature resistant steel plate 1 includes a steel plate body 111, which is provided in two sets. A sandwich plate 112 is fixedly connected between the two sets of steel plate bodies 111. An upper T-shaped strip 11 is fixedly connected to the top surface of the fire-resistant and high-temperature resistant steel plate 1. Three sets of upper T-shaped strips 11 are provided. A lower T-shaped cavity 12 is provided on the bottom surface of the fire-resistant and high-temperature resistant steel plate 1. Three sets of lower T-shaped cavity 12 are provided. The lower T-shaped cavity 12 corresponds to the upper T-shaped strip 11. A hollow groove 13 is provided on one side of the fire-resistant and high-temperature resistant steel plate 1. A locking block 15 is fixedly connected to the other side of the fire-resistant and high-temperature resistant steel plate 1. The locking block 15 is locked inside the hollow groove 13. A first sealing gasket 131 is fixedly connected to the inner wall of the hollow groove 13.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example:

[0030] The upper T-shaped strip 11 is slidably connected to the interior of the corresponding lower T-shaped cavity 12.

[0031] A second sealing gasket 151 is fixedly connected to one side of the locking block 15, and the second sealing gasket 151 is in contact with the first sealing gasket 131.

[0032] A cavity 14 is provided on one side of the fireproof and high-temperature resistant steel plate 1, and four sets of cavities 14 are provided. A plug-in block 16 is fixedly connected to the other side of the fireproof and high-temperature resistant steel plate 1.

[0033] The plug block 16 has four sets.

[0034] The plug-in block 16 is matched with the cavity 14. A sealing plate is provided inside the cavity 14. A sealing plate is provided on the side of the plug-in block 16 away from the locking block 15.

[0035] In summary, the fire-resistant and high-temperature resistant steel structure proposed in this utility model allows for the assembly of two sets of fire-resistant and high-temperature resistant steel plates 1. When horizontal splicing is required, the two sets of fire-resistant and high-temperature resistant steel plates 1 are placed flush. The slots 13 and four cavities 14 of one set of fire-resistant and high-temperature resistant steel plates 1 correspond to the locking blocks 15 and four insertion blocks 16 of the other set of fire-resistant and high-temperature resistant steel plates 1. By bringing the two sets of fire-resistant and high-temperature resistant steel plates 1 closer together, the locking blocks 15 are inserted into the cavities of the slots 13, and the second sealing gasket 151 is tightly fitted with the first sealing gasket 131, thereby enhancing the fire resistance of the two sets of fire-resistant steel plates 1. To ensure the stability of the connection of the high-temperature resistant steel plate 1, each set of plug-in blocks 16 is inserted into the cavity 14. At this time, the cavity 14 and the plug-in blocks 16 are engaged and fixed, thus completing the horizontal engagement and fixed assembly connection of the fireproof and high-temperature resistant steel plate 1. When the fireproof and high-temperature resistant steel plate 1 needs to be assembled vertically, one set of fireproof and high-temperature resistant steel plates 1 is placed on top of another set of fireproof and high-temperature resistant steel plates 1. The lower T-shaped groove 12 at the bottom of the upper fireproof and high-temperature resistant steel plate 1 corresponds to the upper T-shaped strip 11 at the top of the lower fireproof and high-temperature resistant steel plate 1, and each set of upper T-shaped strips 11 is aligned with the corresponding position. The lower T-shaped groove 12 slides in, allowing each set of upper T-shaped strips 11 to be fully pushed in and inserted along the corresponding lower T-shaped groove 12 track. This aligns the upper and lower sets of fire-resistant and high-temperature resistant steel plates 1, completing the limiting insertion work and thus completing the vertical assembly of the two sets of fire-resistant and high-temperature resistant steel plates 1, making installation convenient. If the fire-resistant and high-temperature resistant steel plates 1 need to be used in long-term projects, the operator can quickly position the two sets of fire-resistant and high-temperature resistant steel plates 1 in advance using the above steps, and then inject glue through the gaps to cure the glue at the assembly joint of the fire-resistant and high-temperature resistant steel plates 1. This is suitable for applications that require both sealing and adjustability. In this scenario, this setup, by adding a positioning mechanism to the fireproof and high-temperature resistant steel plate 1, assists the user in assembling and fixing individual fireproof and high-temperature resistant steel plates 1, expanding the applicability of the insulation board body 1 and improving the installation efficiency of the insulation board body 1; at the same time, when transporting batches of fireproof and high-temperature resistant steel plates 1, the operator can pre-limit and fix the plates through the positioning mechanism, so that the batches of fireproof and high-temperature resistant steel plates 1 can be stably placed on the transport vehicle, and the position of the plates is not easy to shift, which facilitates the user's transportation of batches of fireproof and high-temperature resistant steel plates 1 and improves the practicality of the device;

[0036] In this application, the fire-resistant and high-temperature resistant steel plate 1 adopts a sandwich structure of steel plate + insulation layer + steel plate. The steel plate body 111 is fire-resistant steel, which is a low-alloy steel made by adding alloying elements such as molybdenum. At high temperatures, it can precipitate molybdenum carbide to prevent atomic slip, thereby significantly improving the high-temperature resistance of the fire-resistant and high-temperature resistant steel plate 1. A sandwich panel 112 is sandwiched between the two sets of steel plate bodies 111. The sandwich panel 112 is a rock wool board. The multi-layer material needs to be assembled by welding, bolting or adhesive. The fire-resistant and high-temperature resistant steel plate 1 consists of two layers of fire-resistant steel plate sandwiched with rock wool board, which is fixed by bolts to the peripheral angle steel frame to form an integral heat insulation component, thereby improving the overall performance of the fire-resistant and high-temperature resistant steel plate 1.
