[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0021] The following describes the fireproof cover plate 100 for hanging holes according to an embodiment of the present utility model with reference to the accompanying drawings. Figure 1-Figure 5 As shown, the fireproof cover plate 100 for hanging holes according to an embodiment of the utility model includes a fireproof plate 1, at least one support member 2 and at least one railing 4.

[0022] The fireproof board 1 includes a plurality of fireproof sub-boards 11, and the plurality of fireproof sub-boards 11 are arranged at intervals along a first preset direction. A support 2 is provided on one of two adjacent fireproof sub-boards 11, and the other of the two adjacent fireproof sub-boards 11 is supported on the support 2, that is, the two adjacent fireproof sub-boards 11 are matched through the support 2. A first fireproof seal 3 is provided between the other of the two adjacent fireproof sub-boards 11 and the support 2.

[0023] At least one railing 4 is provided in a one-to-one correspondence with at least one fireproof sub-board 11. That is, the number of railings 4 may be equal to the number of fireproof sub-boards 11, and each fireproof sub-board 11 is provided with a railing 4. The number of railings 4 may also be less than the number of fireproof sub-boards 11, and railings 4 are provided on different fireproof sub-boards 11 so that each of a part of the fireproof sub-boards 11 is provided with a railing 4.

[0024] According to the embodiment of the utility model, the fireproof cover plate 100 for the hanging hole is provided with a plurality of fireproof sub-plates 11 and a first fireproof seal 3 is provided between two adjacent fireproof sub-plates 11, so that it not only has a fireproof function, but also each fireproof sub-plate 11 has a small mass, so that the fireproof sub-plate 11 can be easily and labor-savingly lifted and covered. In addition, the number of fireproof sub-plates 11 can be selected according to the size of the hanging hole 210, so as to improve the applicability of the fireproof cover plate 100 for the hanging hole.

[0025] According to the embodiment of the utility model, the fireproof cover plate 100 for the hanging hole is provided with the railing 4 on the fireproof sub-plate 11, so that not only the railing 4 can be installed at the same time as the fireproof sub-plate 11 is installed, so as to reduce the installation steps of the fireproof cover plate 100 for the hanging hole, but also the fireproof sub-plate 11 can be lifted and covered by holding the railing 4, so as to facilitate lifting and covering the fireproof sub-plate 11.

[0026] Therefore, the fireproof cover plate 100 for the hanging hole according to the embodiment of the utility model has the advantages of being fireproof, small in weight, easy to lift under the cover, strong in applicability, and having fewer installation steps.

[0027] The building 1000 according to the embodiment of the utility model includes a floor 200 and a hanging hole fireproof cover plate 100. The floor 200 is provided with hanging holes 210 that penetrate in the up-down direction, that is, the hanging holes 210 penetrate the floor 200 in the up-down direction. The fireproof board 1 of the hanging hole fireproof cover plate 100 is provided on the upper surface of the floor 200, and the fireproof board 1 covers the hanging hole 210. The building 1000 can be an industrial plant (for example, a multi-story production plant of a power station), other industrial buildings or civil buildings, etc.

[0028] like Figure 1 and Figure 2As shown, the floor 200 includes a plate body 220, a water retaining ring 230 and a metal plate 250. The plate body 220 is provided with a hanging hole 210 that passes through in the up-down direction, that is, the hanging hole 210 passes through the plate body 220 in the up-down direction. Figure 1 As shown by arrow C in FIG. The water retaining ring 230 is disposed on the upper surface of the plate body 220 , and the water retaining ring 230 is disposed around the hanging hole 210 , that is, the hanging hole 210 is located on the inner side of the water retaining ring 230 .

[0029] The metal plate 250 is arranged on the upper surface 235 of the water retaining ring 230, and the fireproof board 1 is supported on the upper surface of the metal plate 250 so that the fireproof board 1 covers the hanging hole 210. A second fireproof seal 240 is arranged between the metal plate 250 and the fireproof board 1. In other words, the second fireproof seal 240 is supported on the upper surface of the metal plate 250, and the fireproof board 1 is supported on the upper surface of the second fireproof seal 240.

[0030] The fireproof performance of the hanging hole fireproof cover 100 can be further improved by providing a second fireproof seal 240 between the metal plate 250 and the fireproof board 1. Moreover, by supporting the fireproof board 1 on the upper surface of the metal plate 250, the fireproof board 1 can be installed without providing a mounting slot or other device, so as to save space.

[0031] Optionally, the water retaining ring 230 is a concrete ring, that is, the water retaining ring 230 is made of concrete. The metal plate 250 is a steel plate, and the thickness of the metal plate 250 is greater than or equal to 1 mm and less than or equal to 3 mm. The second fireproof seal 240 is a fireproof expansion seal strip to further improve the fireproof performance of the hanging hole fireproof cover 100. The thickness of the second fireproof seal 240 is greater than or equal to 3 mm and less than or equal to 6 mm.

[0032] like Figure 1 As shown, the water retaining ring 230 includes a first water retaining plate 231, a second water retaining plate 232, a third water retaining plate 233 and a fourth water retaining plate. The first water retaining plate 231 and the second water retaining plate 232 are arranged relative to each other along a first preset direction. The first preset direction may be the length direction of the hanging hole 210 (the length direction of the fireproof board 1). Figure 1 As shown by arrow D in FIG.

[0033] The third water baffle 233 and the fourth water baffle are arranged relative to each other along a second preset direction, and the first preset direction is perpendicular to the second preset direction. The second preset direction can be the width direction of the hanging hole 210 (the width direction of the fireproof board 1). The first water baffle 231, the third water baffle 233, the second water baffle 232 and the fourth water baffle are connected end to end in sequence to form a ring. This can make the structure of the water baffle ring 230 more reasonable.

[0034] The fireproof board 1 includes a plurality of fireproof sub-boards 11, which are arranged at intervals along the first preset direction. Therefore, the number of fireproof sub-boards 11 can be selected according to the length of the hanging hole 210, so as to reduce the cost of the fireproof board 1 and reduce the processing time of the fireproof board 1.

[0035] Optionally, the fire protection board 1 includes at least three fire protection sub-boards 11, the first fire protection sub-board 11 of the fire protection board 1 is supported on the upper surface of each of the first water barrier 231, the second water barrier 232 and the fourth water barrier, the last fire protection sub-board 11 of the fire protection board 1 is supported on the upper surface of each of the third water barrier 233, the second water barrier 232 and the fourth water barrier, and the remaining fire protection sub-boards 11 of the fire protection board 1 are supported on the upper surface of each of the second water barrier 232 and the fourth water barrier.

[0036] In order to make the technical solution of the present application easier to understand, the technical solution of the present application is further described below by taking the first preset direction as the left-right direction as an example. The first water baffle 231 is located on the left side of the second water baffle 232. The fireproof sub-board 11 located on the far left is supported on the upper surface of each of the first water baffle 231, the second water baffle 232 and the fourth water baffle, the fireproof sub-board 11 located on the far right is supported on the upper surface of each of the third water baffle 233, the second water baffle 232 and the fourth water baffle, and the remaining fireproof sub-boards 11 of the fireproof board 1 are supported on the upper surface of each of the second water baffle 232 and the fourth water baffle.

[0037] like Figure 3 As shown, one of the two adjacent fireproof sub-boards 11 has a first end face 111 (e.g., a left end face) and a second end face 112 (e.g., a right end face) that are opposite to each other in the first preset direction, and the other of the two adjacent fireproof sub-boards 11 has a third end face 113 (e.g., a left end face) and a fourth end face 114 (e.g., a right end face) that are opposite to each other in the first preset direction. The second end face 112 and the third end face 113 are located between the first end face 111 and the fourth end face 114 in the first preset direction.

[0038] The support member 2 includes a vertical portion 21 and a horizontal portion 22, wherein the vertical portion 21 is disposed on the third end surface 113, and the horizontal portion 22 is connected to the vertical portion 21. In other words, the support member 2 can be substantially L-shaped or T-shaped. One of the two adjacent fireproof sub-boards 11 is supported on the horizontal portion 22, and a first fireproof sealing member 3 is disposed between the bottom surface of the one of the two adjacent fireproof sub-boards 11 and the horizontal portion 22. Thus, the structure of the hanging hole fireproof cover plate 100 can be made more reasonable.

[0039] Optionally, the vertical portion 21 can be welded to the third end face 113 to make the structure of the hanging hole fireproof cover plate 100 more solid. A first fireproof seal 3 can also be provided between the first end face 111 and the vertical portion 21. This can further improve the fireproof sealing performance between two adjacent fireproof sub-boards 11, thereby further improving the fireproof sealing performance of the fireproof board 1 and the hanging hole fireproof cover plate 100.

[0040] Optionally, the first fireproof sealing member 3 is a sheet-shaped fireproof expansion sealing member, and the thickness of the first fireproof sealing member 3 is 3 mm to 5 mm.

[0041] like Figure 5 As shown, the fireproof sub-board 11 includes an upper metal plate 115, a lower metal plate 116 and a fireproof part 117, and the fireproof part 117 is arranged between the upper metal plate 115 and the lower metal plate 116. In this way, the structure of the fireproof sub-board 11 can be more reasonable and the weight can be smaller. Among them, the railing 4 is arranged on the upper metal plate 115 of the corresponding fireproof sub-board 11.

[0042] Optionally, the upper metal plate 115 and the lower metal plate 116 are both steel plates. The fireproof portion 117 can be made of rock wool, and the thickness of the fireproof portion 117 can be 8 mm to 12 mm. The fire resistance limit of the hanging hole fireproof cover plate 100 can reach 1 hour.

[0043] like Figure 4 As shown, the fireproof sub-board 11 further includes a keel 118, the upper end surface of the keel 118 is connected to the upper metal plate 115, and the lower end surface of the keel 118 is connected to the lower metal plate 116. The fireproof part 117 is arranged between the upper metal plate 115, the lower metal plate 116 and the keel 118. Among them, the thickness of the upper metal plate 115 is less than or equal to a preset value, and the thickness of the lower metal plate 116 is less than or equal to a preset value.

[0044] By providing the keel 118 between the upper metal plate 115 and the lower metal plate 116, the structural strength of the fireproof sub-plate 11 can be improved, so that the thickness of the upper metal plate 115 and the lower metal plate 116 can be reduced. In this way, the mass of the fireproof sub-plate 11 can be further reduced, so that the fireproof sub-plate 11 can be lifted and covered more easily and labor-savingly.

[0045] like Figure 4 As shown, the keel 118 includes a first straight keel 1181, a second straight keel 1182, a first oblique keel 1184, a second oblique keel 1185, and a plurality of transverse keels 1183. The first straight keel 1181 and the second straight keel 1182 are arranged at intervals along the first preset direction, and the plurality of transverse keels 1183 are arranged at intervals along the second preset direction. One end (e.g., the left end) of each transverse keel 1183 is connected to the first straight keel 1181, and the other end (e.g., the right end) of each transverse keel 1183 is connected to the second straight keel 1182.

[0046] The first oblique keel 1184 is connected to the first straight keel 1181, the second straight keel 1182 and each transverse keel 1183, and the extension direction of the first oblique keel 1184 intersects each of the first preset direction and the second preset direction. In other words, the extension direction of the first oblique keel 1184 is neither parallel to each of the first preset direction and the second preset direction, nor perpendicular to each of the first preset direction and the second preset direction.

[0047] The second oblique keel 1185 is connected to the first straight keel 1181, the second straight keel 1182 and each transverse keel 1183, and the second oblique keel 1185 is cross-arranged and connected to the first oblique keel 1184. The extension direction of the second oblique keel 1185 intersects each of the first preset direction and the second preset direction. In other words, the extension direction of the second oblique keel 1185 is neither parallel to each of the first preset direction and the second preset direction, nor perpendicular to each of the first preset direction and the second preset direction.

[0048] This can further enhance the effect of the keel 118 in increasing the structural strength, thereby further reducing the thickness of the upper metal plate 115 and the lower metal plate 116. This can further reduce the mass of the fireproof sub-board 11, thereby making it easier and more labor-saving to lift and cover the fireproof sub-board 11.

[0049] Alternatively, if Figure 4 As shown, one end of the first oblique keel 1184, one end of the first straight keel 1181, and one end of a transverse keel 1183 are connected to each other, and one end of the second oblique keel 1185, one end of the second straight keel 1182, and the other end of the transverse keel 1183 are connected to each other. The other end of the first oblique keel 1184, the other end of the second straight keel 1182, and one end of another transverse keel 1183 are connected to each other, and the other end of the second oblique keel 1185, the other end of the first straight keel 1181, and the other end of the other transverse keel 1183 are connected to each other. In this way, the effect of the keel 118 on increasing the structural strength can be further improved, thereby further reducing the thickness of the upper metal plate 115 and the lower metal plate 116.

[0050] That is, the first straight keel 1181, the one transverse keel 1183, the second straight keel 1182 and the other transverse keel 1183 are connected end to end in sequence to form a rectangular portion, thereby further reducing the mass of the fireproof sub-board 11, thereby making it easier and more labor-saving to lift and cover the fireproof sub-board 11.

[0051] Optionally, the number of railings 4 may be equal to the number of fireproof sub-boards 11, and a plurality of railings 4 may be connected to a plurality of fireproof sub-boards 11 one by one, so that a railing 4 is provided on each fireproof sub-board 11. Optionally, the railings 4 are integrally formed with the upper metal plate 115 of the corresponding fireproof sub-board 11, or the railings 4 are welded to the upper metal plate 115 of the corresponding fireproof sub-board 11. The height of the railings 4 may be 400 mm-700 mm.
