Description

Technical Field

[0001] The utility model relates to the technical field of keels, in particular to a keel with high sound insulation effect. Background Art

[0002] The keel frame is a structural support method, commonly used in fields such as construction, engineering and manufacturing. In construction, the keel frame usually refers to the skeleton system used to support the building structure. The keel frame is built on a steel frame or concrete frame inside the building. It can bear the weight of the building and transfer gravity to the foundation to ensure the stability and safety of the building. The keel frame system usually contains reserved holes and spaces for various pipes and wires, which is convenient for the subsequent installation of facilities, such as electrical systems, plumbing systems, etc., which improves the functionality and practicality of the building. The keel frame plays an important role in the building structure. It can not only support the weight of the building, but also provide spatial structure, enhance wind and earthquake resistance, and provide convenient conditions for the subsequent installation of facilities.

[0003] For example, application number CN215167096U discloses a building sheet metal keel frame, comprising a main frame; square openings are provided at both front and rear ends of the right side of the main frame, and sheet metal strips are inserted in the square openings, sliding blocks are welded on the inner ends of the inner sides of the sheet metal strips, and transverse grooves are penetrated through the inner sides of the sheet metal strips and located on the right side of the sliding blocks, sliding grooves are provided on both front and rear sides of the inner wall of the main frame, and blocks are arranged in the sliding grooves; the beneficial effect of the utility model is that when the second main frame is moved to the right side of the first main frame, the extended sheet metal strip can be aligned with the position of the square openings 2 of the second main frame, and then the sheet metal strip can be tightly inserted into the adjacent square openings 2 through the anti-slip sheet, thereby supporting the lower main frame, and then fixing the second main frame to the ceiling according to the method of installing the first main frame, and no hand support is required at all times during the installation process, which effectively reduces the labor intensity of the installers and can effectively improve the installation efficiency.

[0004] However, this kind of building sheet metal keel frame does not take into account that most existing keel frames do not have space for installing sound insulation materials after installation, and the single partition material has poor sound insulation effect. The lack of sound insulation materials will cause the spread and penetration of sound.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a keel with high sound insulation effect is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a keel with high sound insulation effect, so as to solve the problem that a single partition material proposed in the above background technology has poor sound insulation effect and lack of sound insulation material will lead to the propagation and penetration of sound.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a keel with high sound insulation effect, including a keel frame, the keel frame is S-shaped and symmetrically provided with two groups of rock wool, and an installation space is left between the two groups of rock wool, a fire-resistant gypsum board is arranged on the keel frame, and there are three groups of fire-resistant gypsum boards respectively located on both sides and the middle part of the keel frame, and a sound insulation felt is arranged in the middle part of the keel frame.

[0008] Furthermore, a plurality of groups of limiting plates are symmetrically arranged on the keel frame, and a plurality of groups of through holes are symmetrically opened on the keel frame.

[0009] Furthermore, a first L-shaped plate is fixedly arranged on the keel frame, and two groups of the first L-shaped plates are symmetrically arranged at two ends of the keel frame.

[0010] Furthermore, two groups of U-shaped plates are movably provided at both ends of the keel frame.

[0011] Furthermore, two groups of second L-shaped plates are fixedly arranged on the U-shaped plate, and the second L-shaped plates can form an inter-hooking connection effect with the first L-shaped plates.

[0012] Furthermore, the sound insulation felt can effectively prevent the propagation of sound and reduce the possibility of sound penetrating into other areas or rooms.

[0013] Furthermore, the rock wool has good heat insulation performance and can effectively prevent the conduction and propagation of heat.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model provides a sound insulation felt. When a keel with high sound insulation effect is used, the sound insulation felt is arranged in the space between two groups of rock wool and is located in the middle part of the keel frame. The sound insulation felt can effectively prevent the propagation of sound, absorb sound wave energy in the air, and reduce the possibility of sound penetrating into other areas or rooms. Rock wool has good thermal insulation performance and can effectively prevent the conduction and propagation of heat, reduce the temperature difference between indoor and outdoor, and reduce energy consumption. The fire-resistant gypsum board is arranged on both sides of the keel frame to form a clamping and protective effect on the rock wool and the sound insulation felt. The fire-resistant gypsum board has good fireproof performance and can effectively prevent the spread of flames and prevent the spread of fire, thereby effectively solving the problem that a single partition material has a poor sound insulation effect and a lack of sound insulation material will lead to the propagation and penetration of sound.

[0016] 2. The utility model sets a U-shaped plate, which is wider than the keel frame. After the sound insulation felt, rock wool and fire-resistant gypsum board are installed, the first L-shaped plate and the second L-shaped plate are symmetrically hooked with each other through one end of the keel frame. The sliding U-shaped plate can form a protective wrapping effect on one end of the keel frame, and the fire-resistant gypsum board can be clamped and fixed by the two sides of the U-shaped plate, which effectively improves the firmness of the installation and reduces the problem of separation caused by stratification.

[0024] Furthermore, when a keel with high sound insulation effect is used, the sound insulation felt 13 is arranged in the space between the two groups of rock wool 12 in the middle part of the keel frame 1. The sound insulation felt 13 can effectively prevent the propagation of sound, absorb the sound wave energy in the air, and reduce the possibility of sound penetrating into other areas or rooms. The rock wool 12 has good thermal insulation performance, can effectively prevent the conduction and propagation of heat, can reduce the temperature difference between indoor and outdoor, and reduce energy consumption. The fire-resistant gypsum board 14 is arranged on both sides of the keel frame 1 to form a clamping protection effect for the rock wool 12 and the sound insulation felt 13. The fire-resistant gypsum board 14 has good fireproof performance, can effectively prevent the spread of flames, and prevent the spread of fire, thereby effectively solving the problem that the sound insulation effect of a single partition material is poor and the lack of sound insulation material will lead to the propagation and penetration of sound.

[0025] Furthermore, a plurality of groups of limiting plates 11 are symmetrically arranged on the keel frame 1, and a plurality of groups of through holes 111 are symmetrically opened on the keel frame 1. The limiting plates 11 are used to limit the layered installation of the installed sound insulation felt 13 and rock wool 12, and can be fixed to the installed sound insulation felt 13 and rock wool 12 by tightening the through holes 111 of the components, so that the installation is convenient and the installation efficiency is improved.

[0026] Embodiment 2

[0027] like Figure 2 and Figure 3 As shown, the utility model proposes a keel with high sound insulation effect. Compared with the first embodiment, as another implementation mode of the utility model, a first L-shaped plate 112 is fixedly arranged on the keel frame 1, and the first L-shaped plate 112 is symmetrically arranged in two groups at the two ends of the keel frame 1, and two groups of U-shaped plates 2 are movably arranged at both ends of the keel frame 1, and two groups of second L-shaped plates 21 are fixedly arranged on the U-shaped plate 2, and the second L-shaped plate 21 can form an interhooking connection effect with the first L-shaped plate 112.

[0028] Furthermore, the U-shaped plate 2 is wider than the keel frame 1. After the sound insulation felt 13, rock wool 12 and fire-resistant gypsum board 14 are installed, the first L-shaped plate 112 and the second L-shaped plate 21 are symmetrically hooked together through one end of the keel frame 1. The sliding U-shaped plate 2 can form a protective wrapping effect on one end of the keel frame 1, and the fire-resistant gypsum board 14 can be clamped and fixed through both sides of the U-shaped plate 2, which effectively improves the firmness of the installation and reduces the problem of separation due to stratification.

[0030] Finally, the U-shaped plate 2 is wider than the keel frame 1. After the sound insulation felt 13, rock wool 12 and fire-resistant gypsum board 14 are installed, the first L-shaped plate 112 and the second L-shaped plate 21 are symmetrically hooked together through one end of the keel frame 1.
