Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure fireproof covering system with fire-resistant and heat-insulating properties. Background Art

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. In steel structures, each component or part is connected by a weld, bolt or rivet. Steel structures have the characteristics of high strength, light weight, strong deformability, good toughness and high reliability. The application of steel structures in construction projects can effectively improve the performance of construction projects and save construction project costs. Replacing concrete structures with steel structures can reduce the use of sand, stone and cement, and reduce damage to non-renewable resources. Although steel structures have the characteristics of high strength and good toughness, they have poor fire resistance. In the event of a fire, after a long period of burning, the steel structure is likely to lose its high strength, which will lead to the collapse of the entire building. For this reason, a steel structure fireproof cladding system with fire-resistant and heat-insulating properties is proposed to solve the above-mentioned problems. Utility Model Content

[0003] The utility model aims at the problem that steel structures have poor fire resistance and are prone to lose their high strength performance after long-term burning, thus causing the entire building to collapse. The utility model provides a steel structure fireproof covering system with fire-resistant and heat-insulating performance. By installing fire-resistant and heat-insulating panels on the steel structure, the fire resistance of the steel structure is improved, thereby preventing the steel structure from losing its high strength performance and the building from collapsing, and effectively solving the problems mentioned in the above-mentioned background technology.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] A steel structure fireproof covering system with fire-resistant and heat-insulating properties comprises an H-shaped steel, wherein the upper and lower ends of the H-shaped steel are respectively provided with a column upper end plate and a column lower end plate, and a plurality of fixing holes are respectively opened on the column upper end plate and the column lower end plate; a plurality of floating bead fire-resistant and heat-insulating panels covering the H-shaped steel are provided at the outer periphery of the H-shaped steel, and a cavity is provided between the floating bead fire-resistant and heat-insulating panels and the H-shaped steel.

[0006] A plurality of keels are fixedly connected to the H-shaped steel, and the floating bead fireproof insulation panels are respectively installed on the corresponding keels.

[0007] The floating bead fireproof insulation board is provided with a plurality of fixing bolts, which are respectively threadedly connected to corresponding keels.

[0008] The floating bead fireproof insulation board is fixed on the corresponding keel by gluing.

[0009] The inner wall of the H-shaped steel is provided with a plurality of caulking plates matched with the floating bead fireproof insulation board.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] A steel structure fireproof covering system with fire-resistant and heat-insulating properties, wherein a floating bead fire-resistant insulation board is coated on the outer surface of an H-shaped steel, which can effectively insulate the H-shaped steel. In the event of a fire, the insulation properties of the floating bead fire-resistant insulation board can prevent the temperature of the H-shaped steel from being too high, that is, prevent the high-strength performance of the H-shaped steel from being reduced, and further prevent the collapse of the building; a cavity is provided between the floating bead fire-resistant insulation board and the H-shaped steel, and the provided cavity can prevent the inner end face of the floating bead fire-resistant insulation board from contacting the H-shaped steel, thereby further reducing the heat conduction effect and preventing the heat on the inner end face of the floating bead fire-resistant insulation board from being transferred to the H-shaped steel.

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0017] like Figure 1-3 As shown, the utility model provides a steel structure fireproof covering system with fire-resistant and heat-insulating properties, including an H-shaped steel 1, wherein the upper and lower ends of the H-shaped steel 1 are respectively provided with a column upper end plate 2 and a column lower end plate 6, and a plurality of fixing holes are respectively opened on the column upper end plate 2 and the column lower end plate 6; a plurality of floating bead fire-resistant and heat-insulating panels 4 covering the H-shaped steel 1 are provided at the outer periphery of the H-shaped steel 1, and a cavity 3 is provided between the floating bead fire-resistant and heat-insulating panel 4 and the H-shaped steel 1.

[0018] like Figure 1-2As shown, the H-shaped steel 1 is a steel structure. The column upper end plate 2 and the column lower end plate 6 are used to install and fix the H-shaped steel 1. Through the multiple fixing holes set on the column lower end plate 6, the H-shaped steel 1 can be fixed on the ground or pile foundation by passing bolts through the fixing holes. The column upper end plate 2 can make the H-shaped steel 1 fixedly connected with other steel structures or roofs, so as to support the entire building; the floating bead fire-resistant insulation board 4 is coated on the outer surface of the H-shaped steel 1, which can effectively insulate the H-shaped steel 1. In the event of a fire, the floating bead fire-resistant insulation board 4 has a heat-insulating property that can prevent the H-shaped steel 1 from being overheated, that is, prevent the high-strength performance of the H-shaped steel 1 from being reduced, and further prevent the collapse of the building. The floating bead refractory insulation board 4 has good heat-insulating performance, which is a prior art and will not be repeated here. There is a certain gap between the floating bead refractory insulation board 4 and the H-shaped steel 1, that is, the cavity 3. The cavity 3 is set so that the inner end face of the floating bead refractory insulation board 4 is not in contact with the H-shaped steel 1, thereby further reducing the heat conduction effect and preventing the heat on the inner end face of the floating bead refractory insulation board 4 from being transferred to the H-shaped steel 1.

[0019] A plurality of keels 8 are fixedly connected to the H-shaped steel 1 , and the floating bead fireproof insulation panels 4 are respectively installed on the corresponding keels 8 .

[0020] like Figure 3 As shown, the keel 8 is fixed to the H-shaped steel 1 by bolts, and the floating bead refractory insulation board 4 is fixed to the keel 8, which is equivalent to being fixed to the H-shaped steel 1, and because the keel 8 has a certain thickness, a cavity 3 can be left between the floating bead refractory insulation board 4 and the H-shaped steel 1 during installation, so that the floating bead refractory insulation board 4 does not contact the H-shaped steel 1.

[0021] The floating bead fireproof insulation board 4 is provided with a plurality of fixing bolts 7 , which are respectively threadedly connected to corresponding keels 8 .

[0022] like Figure 3 As shown, the floating bead fire-resistant insulation board 4 is fixed to the corresponding keel 8 by fixing bolts 7, which has good fixing effect and high fire resistance limit, but the disadvantage is that it is not beautiful enough.

[0023] The floating bead fireproof insulation board 4 is fixed to the corresponding keel 8 by gluing.

[0024] like Figure 3 As shown, the floating bead fire-resistant partition board can also be fixed on the keel 8 by gluing. The fixing effect is general, the fire resistance limit is general, and the aesthetics is good. The fixing method is selected according to the actual use requirements.

[0025] The inner wall of the H-shaped steel 1 is provided with a plurality of caulking plates 5 which cooperate with the floating bead fireproof insulation board 4.

[0026] like Figure 3As shown, the caulking plate 5 is fixed to the inner wall of the H-shaped steel 1 by gluing or bolting. When two adjacent floating bead fire-resistant insulation panels 4 are installed and connected, a certain gap will be left in the middle. The caulking plate 5 can be set to seal the gap, thereby further improving the sealing effect, preventing heat from entering in the event of a fire, and further improving the fire resistance of the steel structure.

[0027] When the utility model is in use, the floating bead fire-resistant insulation board 4 is coated on the outer surface of the H-shaped steel 1, which can effectively insulate the H-shaped steel 1. In the event of a fire, the insulation characteristics of the floating bead fire-resistant insulation board 4 can prevent the temperature of the H-shaped steel 1 from being too high, that is, prevent the high strength performance of the H-shaped steel 1 from being reduced, and further prevent the collapse of the building; a cavity 3 is provided between the floating bead fire-resistant insulation board 4 and the H-shaped steel 1, and the inner end face of the floating bead fire-resistant insulation board 4 can be prevented from contacting the H-shaped steel 1 through the provided cavity 3, thereby further reducing the heat conduction effect and preventing the heat of the inner end face of the floating bead fire-resistant insulation board 4 from being transferred to the H-shaped steel 1.

[0028] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
