[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0030] The embodiment of the present application discloses a covering structure for exposed steel beams of a steel structure building.

[0031] Reference Figure 1 and Figure 2 A covering structure for exposed steel beams of a steel structure building, wherein the exposed steel beam 1 is supported under a floor slab 2, and the covering structure is used to cover the exposed steel beam, and at the same time, the decorative panel 3 can be simply installed and fixed on the covering structure. The covering structure includes a thermal insulation spray layer 4, a first connecting member 5 and a second connecting member 6, and the thermal insulation spray layer 4 is sprayed on the exposed steel beam 1 to improve the thermal insulation effect of the exposed steel beam 1; one end of the first connecting member 5 and the second connecting member 6 are both pre-buried in the thermal insulation spray layer 4, and the other ends of the first connecting member 5 and the second connecting member 6 are fixedly connected to the decorative panel 3.

[0032] Specifically, the thermal insulation spray layer 4 is formed by spraying a thermal insulation material, and in this embodiment, the thermal insulation material is set as gypsum mortar. Gypsum mortar is a Class A fireproof material. Using gypsum mortar to spray and fill the gaps around the exposed steel beam 1 can reduce the contact between the exposed steel beam 1 and the air, effectively reduce the heat loss inside the building, so as to achieve the dual effects of fire prevention and thermal insulation, reduce the energy consumption of the building, and help promote the development of green buildings. In addition, decorative panels 3 of different materials can be selected according to needs to make the appearance of the building more beautiful and improve the construction quality.

[0033] The exposed steel beam 1 is an I-beam, comprising a web 11, an upper flange 12 and a lower flange 13. The web 11 is arranged perpendicularly to the floor 2, and the upper flange 12 and the lower flange 13 are respectively welded to both ends of the web 11. The upper surface of the upper flange 12 abuts against the lower surface of the floor 2, and the lower flange 13 is connected to one end of the first connecting member 5.

[0034] In this embodiment, the first connecting member 5 is configured as a channel steel, which is a long steel strip with a C-shaped cross-section. The channel steel itself is light and can withstand a large amount of weight and pressure. The outer surface of one side of the channel steel is fixedly connected to the lower surface of the lower flange 13 by welding, and the connection strength between the channel steel and the lower flange 13 can be improved by welding; the outer surface of the other side of the channel steel abuts against the inner side of the decorative panel 3 below. The channel steel is connected to the lower decorative panel 3 by self-tapping screws, so that the decorative panel 3 can be fixed to the lower surface of the exposed steel beam 1 through the channel steel. In this embodiment, two first connecting members 5 are provided as an example for explanation. The openings of the two channel steels are facing away from the side where the web 11 is located, and the two channel steels are symmetrically arranged relative to the web 11, which can achieve stable installation of the decorative panel 3 and extend the service life of the exposed steel beam 1 and the cladding structure.

[0035] Furthermore, leveling layers 8 are laid on both indoor and outdoor sides of the thermal insulation spray layer 4, respectively, so as to facilitate the connection of the decorative panel 3 or the external decorative surface 9 on the surface of the thermal insulation spray layer 4. The thermal insulation spray layer 4 is connected to the indoor decorative panel 3 through a second connecting member 6, and the second connecting member 6 is located on the indoor side of the thermal insulation spray layer 4. One end of the second connecting member 6 is embedded in the thermal insulation spray layer 4, and the other end passes through the leveling layer 8 to connect to the indoor decorative panel 3. In this embodiment, the second connecting member 6 is configured as a rivet, which has a strong supporting capacity, will not cause cracking or peeling of the lining due to thermal expansion mismatch, and is convenient to construct, so rivets are used as connectors between the exposed steel beam 1 and the indoor decorative panel 3.

[0036] In order to realize the connection between the exposed steel beam 1 and the outdoor external decoration 9, the present embodiment also includes a third connecting member 7 arranged on the outdoor side of the thermal insulation spray layer 4. One end of the third connecting member 7 is embedded in the thermal insulation spray layer 4, and the other end passes through the leveling layer 8 to connect with the outdoor external decoration 9. In the present embodiment, the third connecting member 7 includes an embedded bolt 71 and an angle steel 72, one end of the embedded bolt 71 is embedded in the thermal insulation spray layer 4, and the other end of the embedded bolt 71 passes through the leveling layer 8 and is fixed to the angle steel 72. At this time, one end of the angle steel 72 is abutted against the outside of the leveling layer 8 and is installed on the leveling layer 8 through the embedded bolt 71, and the other end of the angle steel 72 is connected to the outdoor external decoration 9. The embedded bolt 71 has a stronger supporting capacity, can withstand the load transmitted by the external decoration 9, and is convenient to construct.

[0037] The implementation principle of the embodiment of the present application is as follows: during construction, the channel steel is first welded to the lower surface of the lower flange 13 of the exposed steel beam 1, and the thermal insulation spray layer 4 is formed by spraying gypsum mortar, and the channel steel, rivets and embedded bolts 71 are embedded in the thermal insulation spray layer 4. After the gypsum mortar is formed, the channel steel, rivets and embedded bolts 71 are fixed in the thermal insulation spray layer 4. Then, the decorative panel 3 is fixed to the thermal insulation spray layer 4 through the channel steel and rivets to solve the problem that the exposed steel beam 1 can fix the decorative panel 3 while insulating. In addition, the external decorative surface 9 is fixed to the outdoor side by the embedded bolts 71 and the angle steel 72, thereby realizing the connection between the thermal insulation spray layer 4 and the external decorative surface 9.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
