[0048] Figure 6 is a structure diagram of the double-layer outer layer unit plate in this embodiment; Figure 7 Figure 6 is a sectional view of the A-A section in

[0049] As shown in Figure 6 and Figure 7 , the face direction of the double-layer fireproof outer layer plate 133 is also parallel to the height direction of the seismic isolation support 11. Each double-layer fireproof outer layer plate 133 is formed by combining two double-layer outer layer unit plates 133A which are the same in structure.

[0050] Each double-layer outer layer unit plate 133A includes a first fireproof outer layer plate 1331 and a second fireproof outer layer plate 1332, which are both in the shape of a rectangular plate and are stacked in the thickness direction, and a glue joint (glue layer) is formed between the two, that is, the two fireproof outer layer plates are fixed by glue, and in this embodiment, the glue is professional glue. Among them, the width of the first fireproof outer layer plate 1331 is less than that of the second fireproof outer layer plate 1332, and the lengths of the two are basically the same. In the width direction, one end of the first fireproof outer layer plate 1331 is aligned with one end of the second fireproof outer layer plate 1332, so that the other end of the second fireproof outer layer plate 1332 is exposed from the other end of the first fireproof outer layer plate 1331, and the two ends in the length direction are aligned, that is, one end of the double-layer outer layer unit plate 133A in the width direction is in the shape of a step, and the other end (the other end in the width direction) of the double-layer outer layer unit plate 133A opposite to the stepped end has a plurality of outer plate fixing holes 1333. In use, the stepped ends of the two double-layer outer layer unit plates 133A are spliced towards each other, thereby forming a double-layer fireproof outer layer plate 133 in the shape of a rectangular plate as a whole.

[0051] In this embodiment, the thickness of the first fireproof outer layer plate 1331 is 14 mm, and the thickness of the second fireproof outer layer plate 1332 is also 14 mm, that is, the total thickness of the double-layer fireproof outer layer plate 133 is about 36 mm. The length of the first fireproof outer layer plate 1331 and the second fireproof outer layer plate 1332 is the side length of the upper end steel plate 111 plus 28 mm, the width (height after installation) H2 of the first fireproof outer layer plate 1331 is the total height H of the seismic isolation support 11 divided by 2 minus 25 mm (H2 = H / 2-25), and the width of the second fireproof outer layer plate 1332 is the width H2 of the first fireproof outer layer plate 1332 plus 50 mm. After splicing, the width of the double-layer fireproof outer layer plate 133 is the total height H of the seismic isolation support 11 plus 200 mm.​

[0052] In an alternative, the double-layer outer layer unit plate 133A can also be made into a monolithic plate with an overall shape as shown in Figure 6 and Figure 7 .

[0053] In this embodiment, each double-layer outer layer unit plate 133A has four outer plate fixing holes 1333 arranged at equal intervals along its length direction, with an interval less than or equal to 300 mm, and the distance from the outer plate fixing hole 1333 to one end of the double-layer outer layer unit plate 133A in the width direction is 50 mm. Each outer plate fixing hole 1333 is a counterbore for setting a gasket.

[0054] As shown in Figure 1 , during installation, the distance between the upper end of the double-layer fireproof outer layer plate 133 and the upper end of the shock isolation support 11 is 100 mm, and the distance between the lower end of the double-layer fireproof outer layer plate 133 and the lower end of the shock isolation support 11 is 100 mm.

[0055] In this embodiment, both the first fireproof outer layer plate member 1331 and the second fireproof outer layer plate member 1332 are magnesium-based floating bead high-crystal composite fireproof plates, which are excellent fireproof building materials. They are mainly composed of magnesium-based materials, floating beads, and glass fiber cloth. Among them, the magnesium-based material provides good fire resistance and certain strength; the floating bead is a hollow micro glass bead with the characteristics of light weight, heat insulation, and heat preservation; the glass fiber cloth serves as a reinforcing material to increase the strength and toughness of the fireproof plate. The magnesium-based floating bead high-crystal composite fireproof plate has excellent fireproof performance and can maintain good stability at high temperatures, is not easy to burn, has a high fire resistance limit, and can effectively block the spread of fire when on fire. Moreover, it also has good heat insulation performance. The hollow structure of the floating bead and the characteristics of the material itself make the magnesium-based floating bead high-crystal fireproof plate have excellent heat insulation effect, which can effectively reduce the heat transfer to the double-layer fireproof inner layer plate 132.

[0056] The magnesium-based floating bead high-crystal composite fireproof plate used in this embodiment has a fireproof grade of A1, a thickness of about 28 mm, can withstand a high temperature of 1300℃, and has a fire resistance limit of more than 3 hours.

[0057] The outer plate fixing member 134 includes a bolt, a nut and a gasket. The bolt passes through the outer plate fixing hole 1333 on the double-layer fireproof outer layer plate 133, the mounting hole on the fixing steel plate, and the gasket is embedded in each outer plate fixing hole 1333. The nut is sleeved on the bolt, so as to fix the double-layer fireproof outer layer plate 133 on the side edge of the upper end steel plate 111 and the lower end steel plate 112 of the seismic support 11. Optionally, the upper support 121 and the lower support 122 also have corresponding mounting holes, and the bolt also passes through the mounting hole thereon. After the double-layer fireproof outer layer plate 133 is fixed by the outer plate fixing member 134, the double-layer fireproof outer layer plate 133 will press the inner double-layer fireproof inner layer plate 132 on one side of the seismic support 11, that is, the inner fireproof rock wool board does not need additional fixing members.

[0058] Figure 8 is a sectional view of the fireproof assembly in the embodiment, and the overall assembly structure is shown for convenience, Figure 8 The double-layer fireproof inner layer plate and the double-layer fireproof outer layer plate are respectively shown as single plates in the figure.

[0059] As shown in Figure 8 , the adjacent two double-layer fireproof inner layer plates 132 and the adjacent two double-layer fireproof outer layer plates 133 are respectively connected by the edge-to-face splicing mode, that is, one side of one surface (one surface in the thickness direction) of each double-layer fireproof inner layer plate 132 is connected with one side end surface (one end surface in the length direction) of the adjacent double-layer fireproof inner layer plate 132, and the one side end surface (one end surface in the length direction) of the double-layer fireproof inner layer plate 132 is connected with one surface (one surface in the thickness direction) of the other adjacent double-layer fireproof inner layer plate 132. The double-layer fireproof outer layer plate 133 is also the same, and the fireproof assembly 13 formed thereby is substantially in the shape of a rectangular cylinder, which surrounds the middle section of the seismic support 11.

[0060] During installation, the double-layer fireproof inner layer plate 132 is first placed on the outer periphery of the seismic support 11, and then the double-layer fireproof outer layer plate 133 (two double-layer outer unit plates 133A) is placed outside the double-layer fireproof inner layer plate 132, and a plurality of outer plate fixing members 134 are installed to fix the double-layer fireproof outer layer plate 133, so that the installation of the fireproof assembly 13 is completed, and the installation is very convenient.

[0061] For daily inspection and maintenance of fireproofing, the main observation during daily inspection is the structure and appearance of the fireproof assembly 13, and whether the fireproof material is missing and whether the fixing bolt is loose and falls off. If the internal structure needs to be checked, the outer plate fixing member 134 (i.e. the bolt, etc.) is first removed, the double-layer fireproof outer layer plate 133 is removed, and then the double-layer fireproof inner layer plate 132 is removed from the inside. After the inspection is completed, each part is reset in sequence according to the above installation steps.

[0062] When replacing the fireproof assembly 13, the components are sequentially removed according to the above-described dismounting steps, residual materials are cleaned, and then the new fireproof assembly 13 components are sequentially installed according to the above-described mounting steps, and the outer periphery of the seismic support 11 is wrapped, and the work is completed.

[0063] The embodiment has the following effects and advantages:

[0064] According to the fireproof assembly for a seismic support and the seismic support device provided in the embodiment, the fireproof assembly includes multiple fireproof inner layer plates and multiple fireproof outer layer plates, wherein the fireproof inner layer plates are one or more layers of fireproof rock wool plates, and the fireproof outer layer plates are one or more layers of magnesium-based floating bead high-crystal composite fireproof plates. The fireproof rock wool plates have fine and flexible fibers, low slag ball content, and low thermal conductivity, and have excellent heat preservation and insulation effects. The magnesium-based floating bead high-crystal composite fireproof plates have excellent fireproof performance and good heat insulation performance, can maintain good stability at high temperatures, are not easy to burn, have a high fire resistance limit, effectively block the spread of fire, and effectively reduce the heat transfer to the inner layer, so as to ensure that the temperature inside the seismic support can be controlled at room temperature even in the case of external high temperature, thereby ensuring the performance of the seismic support product. The fireproof assembly also has the advantages of relatively fewer components, easy installation, and high cost performance.

[0065] In the embodiment, the double-layer fireproof inner layer plate is composed of two fireproof rock wool plates with different sizes, and forms a double-layer fireproof inner layer plate with stepped ends, so that the fireproof inner layer plate can be more conveniently made into the overall shape and the heat insulation effect is guaranteed. Similarly, each unit plate in the double-layer fireproof outer layer plate is composed of two magnesium-based floating bead high-crystal composite fireproof plates with different sizes, so that the unit plate can be conveniently made into the overall shape.
