Technical Field

[0001] The present application relates to the technical field of assembled steel structure buildings, and in particular to a pipeline beam-penetrating sealing structure. Background Art

[0002] In steel structure buildings, in order to increase the indoor height, increase the effective use space, and meet the requirements of decoration effect, it is inevitable to open holes in the web of the structural I-beam to facilitate the installation of mechanical and electrical pipelines. The I-beam includes the upper flange plate, the lower flange plate and the web of the steel beam, and the web of the steel beam is located between the upper flange plate and the lower flange plate of the steel beam. The web of the steel beam is provided with an opening for the installation of mechanical and electrical pipelines.

[0003] However, opening holes in the web of I-beams will reduce the sound insulation and thermal insulation performance between rooms. Because the HVAC and lighting pipelines are complicated, there is no good way to seal the beam penetration. Usually, the whole is covered by decoration and ceiling. Although this treatment looks more beautiful, it is difficult to meet the requirements of sound insulation and thermal insulation between rooms. Utility Model Content

[0004] In order to improve the sound insulation and heat preservation performance of the I-beam threading point, the present application provides a pipeline beam-penetrating sealing structure.

[0005] The present application provides a pipeline beam plugging structure that adopts the following technical solution:

[0006] A pipeline beam-penetrating sealing structure comprises a sealing plate disposed on opposite sides of a steel beam web, wherein a cavity is formed between the sealing plate and the I-beam, and an opening is located in the cavity; and further comprises a sound-absorbing and heat-insulating material, wherein the sound-absorbing and heat-insulating material is filled in the cavity after the electromechanical pipelines are routed.

[0007] By adopting the above technical solution, a cavity can be formed in the area of ​​the I-beam near the opening by using a sealing plate, and the cavity is sealed by filling the cavity after the electromechanical pipelines are routed, so that the I-beam has better sound insulation and thermal insulation properties.

[0008] Preferably, the sound-absorbing and heat-insulating material is polyurethane.

[0009] By adopting the above technical scheme, polyurethane has the advantages of strong adhesion, good chemical stability, good environmental protection, etc. It also has good thermal insulation and sound insulation capabilities, so that it can fill the remaining space in the cavity after the installation of the electromechanical pipelines is completed, thereby achieving the sealing of the cavity.

[0010] Preferably, the blocking plate is L-shaped as a whole, and includes fixedly connected vertical ribs and side steel plates, the vertical ribs are arranged on opposite sides of the steel beam web, and the side steel plates are located on the side where the vertical ribs are close to each other, and the vertical ribs and the side steel plates are respectively connected to the upper flange plate and the lower flange plate of the steel beam at both ends along the height direction of the steel beam web.

[0011] By adopting the above technical solution, a cavity can be formed through a relatively simple structure by arranging vertical ribs and side steel plates, and the vertical ribs and side steel plates can also play a role in improving the structural strength of the I-beam.

[0012] Preferably, the vertical rib is arranged close to the opening.

[0013] By adopting the above technical solution, the volume of the cavity can be reduced, thereby reducing the amount of sound-absorbing and heat-insulating materials used and saving costs.

[0014] Preferably, a fireproof layer is provided around the I-beam and the sealing plate.

[0015] By adopting the above technical solution, the fireproof layer is used to provide fireproof performance for the I-beam beam and the blocking plate.

[0016] Preferably, a reinforcing rib plate is provided at the edge of the steel beam web close to the opening.

[0017] By adopting the above technical solution, the structural strength of the web of the steel beam near the opening is improved, and deformation of the opening is avoided as much as possible.

[0018] Preferably, the reinforcing rib plates are respectively arranged on opposite sides of the steel beam web.

[0019] By adopting the above technical solution, the structural strength of the web of the steel beam near the opening is further improved by utilizing the reinforcing ribs on both sides.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Utilize the cavity formed by the vertical rib plate, the side steel plate and the I-beam. After the electromechanical pipelines are routed through the openings, high-efficiency sound-absorbing and heat-insulating materials such as polyurethane are filled into the cavity. This not only improves the overall structural strength, but also seals the cavity, making the I-beam where the pipelines pass through better sound insulation and heat preservation.

[0022] 2. By setting up a fireproof layer, the I-beam can have higher fire resistance, so that the I-beam can show higher fire resistance when facing dangerous situations such as fire, ensuring the safety and stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

After the I-beam is processed and formed, the specific position of the opening is confirmed on the web plate 102 according to the pre-embedded point drawing of the electromechanical pipeline 104, and then an opening 103 is opened on the web plate 102, and the opening 103 is used for the electromechanical pipeline 104 to pass through and route.

[0029] The embodiment of the present application discloses a pipeline beam penetration blocking structure.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A pipeline beam plugging structure includes two plugging plates 1, which are respectively located on opposite sides of a steel beam web 102, and a cavity 2 is formed between the two plugging plates 1 and the I-beam, and an opening 103 is located in the cavity 2. The cavity 2 is filled with a sound-absorbing and heat-insulating material 3, and after the electromechanical pipeline 104 is routed, the cavity 2 can be filled and plugged by filling the sound-absorbing and heat-insulating material 3, thereby improving the sound insulation and heat insulation performance of the I-beam threading point.

[0031] The blocking plate 1 is in the shape of an L-shaped plate as a whole, and includes a vertical rib plate 11 and a lateral steel plate 12. The two vertical rib plates 11 are respectively located on both sides of the opening 103 along the height direction of the steel beam web 102. One side of the vertical rib plate 11 is fixedly installed on the steel beam web 102 by welding, and the lateral steel plate 12 is vertically fixedly installed on the other side of the vertical rib plate 11 away from the steel beam web 102 by welding, and the two lateral steel plates 12 are arranged on the side where the two vertical rib plates 11 are close to each other. The vertical rib plate 11 is in the shape of a rectangular plate as a whole, and the plate surface of the vertical rib plate 11 is perpendicular to the plate surface of the steel beam web 102. The length direction of the vertical rib plate 11 is parallel to the height direction of the steel beam web 102, and the two ends of the vertical rib plate 11 in the length direction are respectively fixedly installed on the side where the upper flange plate 100 of the steel beam and the lower flange plate 101 of the steel beam are close to each other by welding. The side steel plate 12 is in the shape of a rectangular plate as a whole, and the plate surface of the side steel plate 12 is perpendicular to the plate surface of the vertical rib plate 11, that is, the plate surface of the side steel plate 12 is parallel to the plate surface of the steel beam web 102.

[0032] In this embodiment, the sound-absorbing and heat-insulating material 3 is made of polyurethane.
