Description

Technical Field

[0001] This utility model relates to the field of residential exhaust ducts, specifically to an installation structure for an external residential exhaust duct. Background Technology

[0002] For a long time, civil building design in my country has included a shared exhaust system in high-rise residential buildings. This system concentrates the fumes from the kitchen and the polluted gases from the bathroom and sends them to the roof, thereby achieving high-altitude dilution and emission, ultimately improving indoor air quality and creating a healthy living environment.

[0003] Current residential shared exhaust systems are built-in flue systems, with the flue length generally matching the floor height. During construction, two prefabricated flues are connected and installed at the floor level. This installation method requires passing through various floors within the building, necessitating construction during the building phase. It suffers from drawbacks such as occupying indoor space and high construction difficulty.

[0004] Traditional external chimney systems involve constructing the remaining outer wall of the chimney after the main structure is completed, followed by plastering, and then applying exterior paint or tiling (or using aluminum panels to seal the exterior). An inner liner is installed inside the chimney to prevent smoke leakage. However, this traditional method is unsuitable for current mid- to high-rise buildings and does not align with the trend towards prefabricated construction. Given the current requirements for green building and fire safety in residential construction, prefabricated external exhaust systems are gradually becoming a new direction for shared residential exhaust systems. Currently, achieving rapid and stable installation of external exhaust systems is a problem that needs to be solved in this field. Utility Model Content

[0011] Furthermore, the cover bracket is plate-shaped, and the length of the cover bracket in the length direction of the external exhaust duct body is set to exceed 80mm.

[0012] According to a specific embodiment of the present invention, the connecting component further includes a diagonal brace, the top end of which is installed on the exterior wall of the building by a fixing member, and the bottom end of which is connected to the covering bracket.

[0013] Furthermore, the angle between the inclined support and the main body of the external exhaust duct along its length is set to 10°-60°.

[0014] According to a specific embodiment of the present invention, the connecting component further includes an auxiliary support, which is connected to the covering support and the inclined support respectively.

[0015] According to a specific embodiment of the present invention, an installation groove is provided on the exterior wall of the building, and the connecting bracket is at least partially located in the installation groove so that the installation component is hidden in the installation groove.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in conjunction with embodiments in order to provide a full understanding of the present invention. However, it should be understood that the following embodiments and detailed description are for illustrative purposes only and do not limit the scope of protection of the present invention.

[0027] Example 1

[0028] Example 1 provides an installation structure for an external exhaust duct in a residential building, such as... Figure 1-2 As shown, it includes multiple external exhaust duct bodies 10, connecting components 20, and installation components 30. The multiple external exhaust duct bodies 10 are installed sequentially by connecting them vertically to form an exhaust channel. The connecting components 20 are set on the external exhaust duct bodies 10 and are used to install the external exhaust duct bodies 10 onto the building exterior wall 40.

[0029] Specifically, the connecting member 20 is mainly used to be installed at the end of the external exhaust duct body 10. In some scenarios, the connecting member 20 can also be installed at other positions of the external exhaust duct body 10, such as the middle.

[0030] The connecting member 20 has a connecting bracket 21 located outside the external exhaust duct body 10. The connecting bracket 21 is provided with a connecting hole 22 facing the building exterior wall 40. The mounting member 30 passes through the connecting hole 22 and is installed into the building exterior wall 40 so that the external exhaust duct body 10 is tightly attached to the building exterior wall 40.

[0031] The mounting component 30 is preferably an anchor bolt connector, such as a chemical anchor bolt. On the same side wall of the external exhaust duct body 10, the number of mounting components 30 is preferably two, three, or even more, as long as effective fixation of the external exhaust duct body 10 is achieved; the specific number is not limited here. Furthermore, when both the connecting bracket 21 and the mounting component 30 are metal parts, they can be welded together to ensure the strength of the connection. In this case, the connection can be achieved regardless of whether there is a connecting hole 22.

[0032] like Figure 4 As shown, a reinforcing frame 11 is preferably prefabricated within the external exhaust duct body 10. A connecting member 20 is connected to the reinforcing frame 11. The reinforcing frame 11 is, for example, a reinforcing steel bar, which is formed directly into the external exhaust duct body 10 during its fabrication process. The reinforcing steel bar is preferably located in the middle of the wall thickness direction. Correspondingly, the connecting member 20 is a metal connector, such as… Figure 3 As shown, it has an inner connection end 23 located inside the external exhaust duct body 10, and the inner connection end 23 is welded to the reinforcing frame 11.

[0033] Please continue reading. Figure 3 The connecting member 20 is specifically Z-shaped. This arrangement not only facilitates the assembly of the mounting member 30, but also makes it easier to shape or assemble the connecting member 20 onto the reinforcing frame 11 during the manufacturing process of the external exhaust duct body 10, thereby connecting it with the external exhaust duct body 10. In other embodiments, the connecting member 20 may also be I-shaped or L-shaped, which will not be elaborated here.

[0034] To further improve the ease of installation and the aesthetics of the assembly joints, the building exterior wall 40 may also be provided with an installation groove 41. The installation groove 41 is used to install the connecting bracket 21, so that the connecting bracket 21 and the mounting component 30 are concealed relative to the surface of the building exterior wall 40. In addition, a pre-embedded fastener adapted to the mounting component 30 may be provided in the installation groove 41. The pre-embedded fastener, for example, is a metal block, which can provide a hole structure adapted to the mounting component 30, thus facilitating a more secure connection between the mounting component 30 and the pre-embedded fastener.

[0035] An assembly process for the installation structure of the residential external exhaust duct in this embodiment is as follows:

[0036] 1) Drill mounting holes 42 that are compatible with the mounting components 30 in sequence on the building exterior wall 40 using a drilling rig. If there are pre-embedded fasteners, the mounting holes 42 are provided by the pre-embedded fasteners.

[0037] 2) For example, the main body 10 of the single-section external exhaust duct is hoisted by means of suspended platform construction operation technology, the connecting hole 22 on the connecting bracket 21 is aligned with the mounting hole 42, and the mounting component 30 is installed.

[0038] 3) Fill the joint between the external exhaust duct body 10 and the building exterior wall 40 with waterproof mortar, such as M15 waterproof mortar;

[0039] 4) After the lower external exhaust duct body 10 is installed in place, waterproof mortar is spread on the upper surface of the lower external exhaust duct body 10.

[0040] 5) Repeat the above operation to install the upper external exhaust duct body 10, keeping the end faces of the upper and lower external exhaust duct body 10 aligned during installation.

[0041] Please continue reading. Figure 1 In this embodiment, a wind cap 50 can also be fitted on the top of the uppermost external exhaust duct body 10. The wind cap 50 is detachably installed on the external exhaust duct body 10, for example, via a connecting flange 60, to guide the exhaust gas in the exhaust duct to be discharged. Specifically, the connecting flange 60 is preferably a metal flange, which has a lower connecting end 61 that can extend into the external exhaust duct body 10 and an upper bearing end 62 that can support the connecting pipe of the wind cap 50. The lower connecting end 61 is fixed to the external exhaust duct body 10, for example, by riveting or bolting. The connecting pipe 51 of the wind cap 50 is supported on the upper bearing end 62 and fixed by bolts, for example, and can also be reinforced by auxiliary welding.

[0042] The external exhaust duct body 10 in the embodiment can be assembled not only in a scenario where it is against a single wall, but also in a scenario where it is against two walls. Both scenarios can achieve rapid assembly and have the advantage of high stability.

[0043] Example 2

[0044] Example 2 provides an installation structure for an external exhaust duct in a residential building. Based on Example 1, the connecting member 20 of Example 2 further includes a covering bracket 24, such as... Figure 5 As shown, the cover bracket 24 is attached to the end of the external exhaust duct body 10, and the connecting bracket 21 is disposed on the cover bracket 24.

[0045] The covering bracket 24 is prefabricated inside the external exhaust duct body 10. Specifically, it is a reinforcing steel plate welded together with the reinforcing frame 11. This helps to improve the overall strength of the end of the external exhaust duct body 10, and helps to form a stable force-bearing system for the external exhaust duct body 10, maintaining the stability of the structure over a long period of time.

[0046] Please continue reading. Figure 5The cover bracket 24 is preferably located in the middle of the external exhaust duct body 10 in the wall thickness direction. The length of the reinforcing member in the length direction of the external exhaust duct body 10 is set to be more than 80mm, for example, 100mm, to ensure effective installation of the mounting member 30 and high structural strength. The length direction here is the height direction when the external exhaust duct body 30 is installed vertically.

[0047] Example 3

[0048] Example 3 provides an installation structure for a residential external exhaust duct. Unlike Example 2, the covering bracket 24 of Example 3 is attached to the outer surface of the end of the external exhaust duct body 10. On the one hand, it can prevent the external exhaust duct body 10 from being damaged by bumps during production and transportation. On the other hand, the connection between the covering bracket 24 and the connecting bracket 21 can be carried out after the external exhaust duct body 10 is manufactured, which is beneficial to optimizing the manufacturing process of the external exhaust duct body 10.

[0049] Example 4

[0050] Example 4 provides an installation structure for an external exhaust duct in a residential building. Based on Example 3, the connecting member 20 of Example 4 further includes a diagonal bracing 25, such as... Figure 7 As shown, the top end of the diagonal brace 25 is installed on the building exterior wall 40 by fasteners 70, such as chemical bolts, and the bottom end of the diagonal brace 25 is connected to the covering bracket 24.

[0051] The inclined bracing 25 in this embodiment provides better support for the external exhaust duct body 10, especially during the initial assembly stage, offering a better inclined bracing effect and improving installation stability. Preferably, the angle between the inclined bracing 25 and the external exhaust duct body 10 along its length is set to 10°-60°, specifically, for example... Figure 7 The 30° shown.

[0052] As an extension of this embodiment, the connecting member 20 further includes auxiliary supports, which are connected to the covering support 24 and the inclined support 25 respectively. Multiple auxiliary supports may be provided, for example, including... Figure 7 The vertical support 26 and the diagonal support 27 shown may also include more forms in other embodiments, which will not be elaborated here.

[0053] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
