Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air ducts, in particular to an air duct made of angle steel. Background Art
[0002] Air duct is a pipe system used for air transportation and distribution. According to the cross-sectional shape, air duct can be divided into circular air duct, rectangular air duct, oblate air duct and other types.
[0003] When the air duct is installed and used, it is mostly installed on a building or other carrier through a hanger structure. This requires the air duct structure to be lightweight in overall weight and not too heavy. Therefore, the current air duct structure is mostly based on iron sheet structure. Although the air duct structure can meet its weight requirements, its safety in use is relatively poor, especially at the corners of the air duct, where the stress point is relatively single and it is easy to deform, which will cause the air tightness to change during subsequent use. For this problem, the current common technical means is to wrap a layer of protective material on the outside of the air duct, which can alleviate the above-mentioned technical problems to a certain extent, but it still cannot avoid the problem of deformation caused by extrusion force due to the small contact surface when hanging.
[0004] Therefore, we propose an angle steel air duct to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide an angle steel air duct to solve the problems raised in the above background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] An angle steel air duct comprises an angle steel and an iron pipe. The angle steels are four in number and are buckled at the four corners of the iron pipe.
[0008] Preferably, a flange structure is fixedly installed at the end position of the angle steel, and a hanging structure for hanging is provided at the top of the angle steel located at the top position of the iron pipe.
[0009] Preferably, a clamping spring is fixedly mounted on the inner side wall of the angle steel via a fastener.
[0010] Preferably, the sheet iron pipe is composed of four pieces of sheet iron, and each piece of sheet iron is independent of each other.
[0011] Preferably, two ends of the iron sheet are respectively inserted between the clamping spring piece and the inner side wall of the angle steel.
[0012] Preferably, a sealing strip is fixedly mounted on the inner side wall of the angle steel and on the side of the clamping spring sheet close to the angle steel.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The angle steel air duct, that is, the iron pipe, that is, the four corners of the entire air duct are completely covered by the angle steels 1. During the subsequent use, the iron pipe, that is, the most vulnerable part of the air duct, is protected, and the angle steel has a large rigidity and will not affect the four corners of the air duct, that is, the four corners of the air duct will not be deformed, which can ensure that the shape of the air duct can be maintained during long-term use, and it is not easy to cause the problem of air tightness change caused by deformation of the four corners due to the action of force.
[0015] 2. The angle steel air duct has each iron sheet that is independent of each other. There is no corner structure when forming the air duct structure, so there will be no problem of affecting the air tightness of the air duct due to deformation of the corner.
[0016] 3. The angle steel air duct and the individually designed iron sheet are used in the practical process of forming the air duct structure. Especially when the iron sheet of the air duct is damaged, the damaged section of the air duct can be directly removed through the flange structure, and then the angle steels at both ends of the damaged iron sheet can be removed. The damaged iron sheet can be removed and replaced, which not only improves the maintenance efficiency, but also reduces the later use and operation and maintenance costs of the air duct.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides a technical solution for the wind duct made of angle steel:
[0022] Embodiment 1:
[0023] like Figure 1 As shown, the air duct is mainly composed of angle steel 1 and iron pipe 2. There are four angle steels in the air duct, and the angle steels 1 are installed at the four corners of the iron pipe 2 to achieve the purpose of protecting the four corners of the iron pipe 2.
[0024] Among them, a flange structure is fixedly welded at the end of the angle steel 1. The flange structure is mainly used for the butt joint installation of sections of air ducts.
[0025] Among them, a hanging structure for hanging is fixedly welded on the top of the two upper angle steels 1. The hanging structure is mainly used for the installation of the air duct, that is, it is connected and fixed with the building through the hanging structure, and the applied force first acts on the angle steel 1, and will not directly act on the iron pipe 2.
[0026] In the present embodiment, during actual use, the iron pipe 2, that is, the four corner structures of the entire air duct, are completely covered by the angle steels 1. During subsequent use, the iron pipe 2, that is, the most vulnerable part of the air duct, is protected, and the angle steel has a large rigidity and will not affect the four corners of the air duct, that is, the four corners of the air duct will not be deformed, which can ensure that the shape of the air duct can be maintained during long-term use, and it is not easy to have problems with air tightness changes caused by deformation of the four corners due to the action of force, and during hoisting, the pulling force generated by the hoisting structure does not directly act on the air duct, and will not easily affect the air duct.
[0027] Embodiment 2:
[0028] like Figure 2 As shown, a clamping spring piece 4 is fixedly mounted on the inner wall of the angle steel 1 by a fastener 3 .
[0029] like Figure 2 As shown, the iron sheet pipe 2 is composed of four iron sheets 5, and the two ends of the iron sheets 5 are inserted between the clamping spring pieces 4 and the inner wall of the angle steel 1.
[0030] Among them, a sealing strip is fixedly installed on the side of the clamping spring piece 4 close to the angle steel 1 and on the inner side wall of the angle steel 1.
[0031] In this embodiment, each iron sheet 5 is independent of each other and has an independent design. When the air duct structure is constructed, there is no corner structure, so the problem of affecting the air tightness of the air duct due to deformation of the corner will not occur.
[0032] Secondly, when the separately designed iron sheet 5 is used in the practical process of forming the air duct structure, especially when the iron sheet 5 of the air duct is damaged, the damaged section of the air duct can be directly removed through the flange structure, and then the angle steels 1 at both ends of the damaged iron sheet 5 can be removed. The damaged iron sheet 5 can be removed and replaced, which not only improves the maintenance efficiency, but also reduces the later use and operation and maintenance costs of the air duct.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
