Description

Technical Field

[0001] The present application relates to the technical field of kitchen and bathroom exhaust duct support construction, and in particular to a kitchen and bathroom exhaust duct support structure. Background Art

[0002] Exhaust ducts in residential kitchens and bathrooms are responsible for channeling cooking fumes and foul air from the bathroom to the outside, maintaining fresh indoor air and a comfortable living environment. Exhaust duct installation and construction must be carried out in strict accordance with specifications to ensure airtightness and stability. During installation, attention must be paid to the precise shape and position of the reserved openings to ensure accurate installation of the duct. The duct must be hoisted into position smoothly, precisely calibrated, and secured to ensure stability. The connection between the duct and the floor, wall, and other structures must be sealed to prevent smoke leakage.

[0003] Currently, to meet fire protection requirements, exhaust ducts in residential kitchens and bathrooms are typically constructed of machine-made glass-magnesium ducts. While there's no unified standard for installation, installation is typically based on recommended local design drawings. The key is the floor support for the duct. Improper support can easily lead to sinking, deformation, and cracking. Currently, angle steel and rebar are the primary support methods used for exhaust ducts.

[0004] Angle steel support Figure 5 In the structure shown, embedded parts are buried at the four corners of the reserved opening in the floor slab, and supporting angle steels are welded to support the load of the upper exhaust duct. The construction procedure is cumbersome, and the support reliability is affected by the firmness of the embedded parts at the bottom of the exhaust duct. In addition, the embedded parts are prone to displacement when the floor slab concrete is poured.

[0005] The steel support structure uses two larger diameter threaded steel bars on the floor to support the load of the upper exhaust duct. Only two sides of the bottom of the exhaust duct are supported on the steel bars. The pressure-bearing area is small, and the side walls of the exhaust duct are unevenly stressed, which can easily cause deformation and cracking.

[0006] Currently, the supporting forces of angle steel and steel bars are uneven, and the defect rate of exhaust ducts cannot meet the project quality. At the same time, the construction is difficult and costly. Summary of the Invention

[0007] In response to the above-mentioned problems, the present application aims to provide a kitchen and bathroom exhaust duct support structure, which realizes stable circumferential support of the exhaust duct, and at the same time solves the problems of deformation and cracking caused by uneven force on the exhaust duct due to the influence of the environment on the floor layer through the shaping ring.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a supporting structure for the exhaust duct in the kitchen and bathroom, the exhaust duct including an upper exhaust duct and a lower exhaust duct located on the upper and lower sides of the floor layer respectively, and a cylinder connecting the upper exhaust duct and the lower exhaust duct, characterized in that: the supporting structure includes a tongue and groove constructed in the floor layer and having an inverted cone-shaped structure, the cylinder is arranged in the tongue and groove, and a supporting component connected to the upper exhaust duct and the lower exhaust duct and positioning the cylinder is arranged in the tongue and groove, and a shaping component is provided in the supporting component for shaping it relative to the cylinder.

[0009] Preferably, the supporting member is a supporting platform arranged along the circumferential direction on the inner wall of the tongue and groove, and the supporting platform is located in the middle of the inner wall of the tongue and groove and is not connected to the upper and lower surfaces of the floor layer.

[0010] Preferably, the shaping member is a shaping ring that is away from the inner side wall of the supporting platform and is pre-embedded in an annular direction within the supporting platform.

[0011] Preferably, the upper side of the inner side wall of the supporting platform is configured as an inverted conical inclined surface structure.

[0012] The beneficial effects of the present application are as follows: the supporting structure disclosed in the present application includes structural components such as tongue and groove, supporting platform, and shaping ring, which realizes stable circumferential support of the exhaust duct. At the same time, the shaping ring solves the problems of deformation, cracking, etc. caused by uneven force on the exhaust duct due to the influence of the environment on the floor layer.

[0019] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Refer to the attached Figures 1 to 4The figure shows a supporting structure for an exhaust duct between a kitchen and a bathroom, wherein the exhaust duct comprises an upper exhaust duct 21 and a lower exhaust duct 22 located on the upper and lower sides of a floor layer 1, respectively, and a cylinder 3 that connects the upper exhaust duct 21 and the lower exhaust duct 22. The cylinder 3 can realize the connection and penetration of the upper exhaust duct 21 and the lower exhaust duct 22 to meet the overall smoke exhaust requirements in high-rise buildings.

[0021] In order to solve the problem of uneven force caused by the exhaust duct being supported by angle steel and steel bars, this application provides a supporting structure, such as Figure 1-2 As shown, it includes a groove 1a (preferably with an inverted tapered angle of 70-75°) formed in the floor 1. The cylinder 3 is positioned in the groove 1a. An upper exhaust duct 21 and a lower exhaust duct 22 are then provided on the upper and lower sides of the floor 1, respectively. The lower exhaust duct 22 is supported by the lower floor 1, while the upper exhaust duct 21 is supported by the upper floor 1. The groove 1a structure ensures support and facilitates demolding after forming.

[0022] In order to support the upper exhaust duct 21 at the groove 1a of each floor slab layer 1, a supporting member is provided in the groove 1a, which is connected to the upper exhaust duct 21 and the lower exhaust duct 22 and positions the cylinder 3. The supporting structure first penetrates the cylinder 3 and then positions it. Then, the upper exhaust duct 21 is vertically supported by the supporting structure, thereby solving the problem that the current support methods such as angle steel and steel bars are difficult to set up. The supporting structure is preferably integrally formed with the floor slab layer 1. After forming, the upper exhaust duct 21 is sleeved on the cylinder 3, and the upper exhaust duct 21 is supported upward by the supporting structure, thereby completing the support operation of the upper exhaust duct 21 for each floor slab layer 1.

[0023] To address the current problems of uneven stress on the exhaust duct caused by angle steel and steel bars, which can lead to deformation and cracking, the supporting structure is equipped with a shaping member that stabilizes it relative to the cylinder 3. This shaping member enhances the integrity of the supporting structure and reduces the deformation caused by thermal expansion and contraction of the floor slab. This ensures the stability of the supporting structure, providing a stable support for the upper exhaust duct 21 and effectively resolving deformation and cracking problems caused by uneven stress.

[0024] Specifically, such as Figure 1-2 As shown, the supporting member is a supporting platform 4 arranged along the inner wall of the tongue and groove 1a in the circumferential direction. It is cast and formed synchronously with the floor layer 1 and the tongue and groove 1a through the template erection. The inner diameter of the supporting platform 4 is equal to that of the cylinder 3 and is used for the penetration and positioning of the cylinder 3. Figure 2In the state shown, the supporting platform 4 is located in the middle of the inner wall of the tongue and groove 1a and is not connected to the upper and lower surfaces of the floor layer 1. In this state, a step is formed between the upper and lower surfaces of the supporting platform 4 and the upper and lower surfaces of the floor layer 1. After the upper exhaust duct 21 and the lower exhaust duct 22 are sleeved on the upper and lower sides of the cylinder 3, the ports of the upper exhaust duct 21 and the lower exhaust duct 22 are abutted against the surface of the supporting platform 4, and the upper exhaust duct 21 is supported. The step formed by the supporting platform 4 and the floor layer 1 is used to limit the ports of the upper exhaust duct 21 and the lower exhaust duct 22, and a sealing layer 6 (such as a sponge strip) can also be filled between the outer walls of the upper exhaust duct 21 and the lower exhaust duct 22 and the inner wall of the tongue and groove 1a.

[0025] In order to achieve the shaping effect on the supporting platform 4, as Figure 2 As shown, the shaping member is a shaping ring 5 that is away from the inner side wall of the support platform 4 and is pre-embedded in the support platform 4 in an annular direction. The shaping ring is preferably made of Ø6mm steel bars and is embedded in the support platform 4 during casting. After the support platform 4 solidifies and takes shape, the annular structure of the shaping ring 5 resists the impact of environmental deformation of the floor layer 1 on the cylinder 3 and the upper and lower exhaust ducts 21 and 22, thereby solving the current problems of deformation and cracking of the exhaust ducts.

[0026] In order to achieve the positioning, fastening and sealing between the cylinder 3 and the supporting platform 4, Figure 3 As shown, the upper side of the inner wall of the support platform 4 is set to an inverted conical inclined surface structure (as shown by the number 4a in the figure), as shown in FIG. Figure 4 As shown, a cavity is formed between the inverted conical slope and the outer wall of the cylinder 3. After the cylinder 3 is inserted into the supporting platform 4, a sealing material 7 such as sealant can be filled into the cavity, thereby improving the positioning and tightness of the two while achieving sealing between the supporting platform 4 and the outer wall of the cylinder 3.

[0027] The principle of this application is: a tongue-and-groove 1a with an inverted cone structure is cast in the floor layer 1, and a supporting platform 4 is cast in the tongue-and-groove 1a at the same time, and a shaping ring 5 is pre-buried in the supporting platform 4. When assembling the exhaust duct support, the cylinder 3 is first positioned in the tongue-and-groove 1a, and the cavity formed between the supporting platform 4 and the outer wall of the cylinder 3 is filled with materials such as sealant to achieve the positioning and sealing of the cylinder 3 on the supporting platform 4. Then, the upper exhaust duct 21 and the lower exhaust duct 22 are sleeved on the upper and lower ports of the cylinder 3 and are against the surface of the supporting platform 4, and then the portion between the outer walls of the upper exhaust duct 21 and the lower exhaust duct 22 and the inner wall of the tongue-and-groove 1a is filled and sealed by the sealing layer 6, thus completing the support assembly operation of the exhaust duct at each floor layer 1.

[0028] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
