Description

Technical Field

[0001] The utility model relates to an air duct installation device, specifically to a fixing bracket for air ducts in steel structure buildings. Background Art

[0002] In the construction of existing steel structure workshops, the fixing brackets of air ducts are usually installed in a welding form. However, this welding fixing method has many deficiencies. Firstly, the high temperature generated during welding will seriously damage the original internal structure of the steel structure, resulting in a decline in the performance of the steel, and further affecting the stability and safety of the entire steel structure workshop. Secondly, welding will also damage the anti-corrosion layer on the surface of the steel structure, making the steel structure more vulnerable to corrosion, thus shortening the service life of the steel structure.

[0003] In addition, using the welding form to fix the air duct bracket also has the problem of low installation efficiency. Welding operations require professional technicians to operate, and the welding process takes a long time, which increases the construction period and cost to a certain extent. At the same time, the welding quality has high requirements for the skills of the operators. Once the welding quality does not meet the standards, it will directly affect the stability and safety of the air duct bracket. Summary of the Utility Model

[0004] Therefore, in order to solve the above deficiencies, the utility model provides a fixing bracket for air ducts in steel structure buildings. This fixing bracket avoids the damage to the steel structure caused by the welding form of the traditional fixing bracket, improves the installation efficiency, and uses the steel structure beam as the load-bearing body of the air duct fixing bracket, ensuring the stability and safety performance of the bracket.

[0005] Specifically, a fixing bracket for air ducts in steel structure buildings includes

[0006] a load-bearing component connected to the steel structure; and

[0007] an air duct cross arm for installing the air duct, which is connected to the load-bearing component and is located below the steel structure;

[0008] The load-bearing component at least includes a long column group and a short column group. The long column group and the short column group are respectively located on both sides of the steel structure. The long column group and the short column group are connected by at least two connecting pieces. One group of connecting pieces is located above the steel structure, and the other is located below the steel structure. The air duct cross arm is connected to the lower part of the long column group.

[0009] Optionally, each group of the long column group includes two long columns, and the two long columns are connected by a connecting plate located above or / and below the steel structure;

[0010] Each group of the short column group includes two short columns, and the two short columns are connected by the connecting plate located above or / and below the steel structure.

[0011] Optionally, the cross arm is horizontally arranged and connected to the two long columns at both ends respectively.

[0012] Optionally, the connecting member passes through the connecting plate and then is connected to the long column or the short column.

[0013] Optionally, the connecting member is a lead screw, and the lead screw is fixedly connected to the long column or the short column through a nut.

[0014] Optionally, the long column, the short column and the connecting plate are all made of angle steel.

[0015] Optionally, the connecting member is fixedly connected to the long column group or the short column group.

[0016] The utility model has the following advantages:

[0017] By using the steel structure beam as the load-bearing body of the air duct fixing bracket, the load-bearing capacity of the system is significantly improved, effectively ensuring the stability and safety of the air duct. Compared with the traditional welding fixing method, this solution does not require welding operations on the steel structure beam, thus avoiding possible damage to the steel structure beam during the welding process, protecting the original mechanical properties and anti-corrosion layer of the steel structure, and extending the service life of the steel structure.

[0018] In addition, all materials in this technical solution are processed and prefabricated on the ground, which not only reduces the safety hazards of high-altitude operations, but also greatly improves the installation efficiency. Since there is no need for hot work at high altitude, there is no need to set up high-altitude hot work protection measures, further simplifying the installation process and reducing the installation cost. At the same time, the ground prefabrication method also makes the installation process more standardized and modular, and only needs to be assembled at high altitude according to requirements, greatly shortening the construction period.

[0019] This technical solution also optimizes the spacing of the air duct fixing brackets to ensure that the bracket spacing is within 20 meters, which can not only meet the air duct fixing requirements of general steel structure workshops with spans within the modulus of 12 meters and 24 meters, but also effectively solve the problem of unreasonable bracket spacing in the traditional fixed bracket welding form. By optimizing the bracket spacing, the installation efficiency is further improved, the number of high-altitude hot work operations is reduced, and thus the overall construction safety is enhanced.

[0026] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0027] In this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0028] As described in the background art, in the construction of existing steel structure workshops, the fixing brackets of air ducts are usually installed by welding. However, there are many deficiencies in this welding fixing method. First of all, the high temperature generated during the welding process will seriously damage the original internal structure of the steel structure, resulting in a decline in the performance of the steel, which in turn affects the stability and safety of the entire steel structure workshop. Secondly, welding will also damage the anti-corrosion layer on the surface of the steel structure, making the steel structure more vulnerable to corrosion, thus shortening the service life of the steel structure.

[0029] In addition, there is also the problem of low installation efficiency when using the welding form to fix the air duct bracket. Welding operations require professional technicians to operate, and the welding process takes a long time, which increases the construction period and cost to a certain extent. At the same time, the welding quality has high requirements for the skills of the operators. Once the welding quality does not meet the standards, it will directly affect the stability and safety of the air duct bracket.

[0030] For the above reasons, this embodiment provides a duct fixing bracket for a steel structure building, as Figures 1-4 shown, the fixing bracket includes:

[0031] a load-bearing member connected to the steel structure; and

[0032] a duct cross arm for installing the duct, the duct cross arm is connected to the load-bearing member and is located below the steel structure;

[0033] The load-bearing member at least includes a long column group and a short column group. The long column group and the short column group are respectively located on both sides of the steel structure. The long column group and the short column group are connected by at least two connecting members. One group of connecting members is located above the steel structure, and the other is located below the steel structure. The duct cross arm is connected to the lower part of the long column group.

[0034] The above technical feature uses a steel structure beam as the load-bearing body of the duct fixing bracket, significantly improving the load-bearing capacity of the system and effectively ensuring the stability and safety of the duct. Compared with the traditional welding fixing method, this solution does not require welding operations on the steel structure beam, thus avoiding possible damage to the steel structure beam during the welding process, protecting the original mechanical properties and anti-corrosion layer of the steel structure, and extending the service life of the steel structure.

[0035] In one embodiment, as Figures 2-4 shown, each group of the long column group includes two long columns 400, and the two long columns 400 are connected by a connecting plate 200 located above or / and below the steel structure 600;

[0036] Each group of the short column group includes two short columns 100, and the two short columns 100 are connected by the connecting plate 200 located above or / and below the steel structure 600.

[0037] The cross arm 500 is horizontally arranged and is respectively connected to the two long columns 400 at both ends.

[0038] The connecting member 300 passes through the connecting plate 200 and then is connected to the long column 400 or the short column 100. Optionally, the connecting member 300 is a lead screw, and the lead screw is connected and fastened to the long column or the short column through a nut; the long column, the short column and the connecting plate are all made of angle steel.

[0039] As Figure 3 and Figure 4, in the embodiment, long columns 400 and short columns 100 are respectively arranged on both sides of the steel structure 600. Connecting plates 200 located above and below the steel structure 600 are installed between adjacent short columns 100 and long columns 400. Then, the long columns and short columns are connected through connecting members 300. During the connection process, the connecting members penetrate through the connecting plates, and the short columns and long columns are fastened by matching nuts with lead screws. A cross arm 500 is horizontally installed between the two long columns through bolts and nuts, and the air duct 700 is installed on the cross arm.

[0040] In another embodiment, as Figure 5 shown, the connecting member 200 is fixedly connected to the long column group or the short column group.

[0041] All materials in this technical solution are processed and prefabricated on the ground, which not only reduces the safety hazards of high-altitude operations but also greatly improves the installation efficiency. Since there is no need to carry out hot work at high altitude, there is no need to set up high-altitude hot work protection measures, further simplifying the installation process and reducing the installation cost. At the same time, the ground prefabrication method also makes the installation process more standardized and modular, and only needs to be assembled at high altitude according to requirements, greatly shortening the construction period.

[0042] This technical solution also optimizes the spacing of the air duct fixing brackets to ensure that the bracket spacing is within 20 meters. This not only meets the air duct fixing requirements of general steel structure workshops with spans within the moduli of 12 meters and 24 meters but also effectively solves the problem of unreasonable bracket spacing in the traditional fixed bracket welding form. By optimizing the bracket spacing, the installation efficiency is further improved, the number of high-altitude hot work operations is reduced, and thus the overall construction safety is enhanced.
