[0002] There are many harms of oil fume to the body. It has a greater impact on the respiratory system, may cause damage to the throat and lungs, etc., and can increase the sensitivity of the airway. Oil fume is an irritating gas. Long-term exposure may also damage the eyes and skin, causing eye congestion, allergies, restlessness, listlessness, drowsiness, fatigue and other symptoms. Therefore, in functional spaces such as generator rooms and commercial areas, high-altitude emissions are adopted for both oil and fume. Therefore, it is necessary to set up an independent flue along the building exterior wall to lead the oil and fume from the generator room or commercial area to the highest point of the building for emission, so as to reduce the impact on the environment.

[0003] The existing flue is arranged against the building exterior wall, and the flue is usually fixed to the building exterior wall and the exterior wall beam. There is a risk of oil and fume infiltrating and leaking into the room, resulting in strange smells in the room; the heat carried by the oil and fume itself is conducted into the room through the wall, which will change the indoor thermal environment and reduce the comfort of people; at the same time, the high-speed flow of air causes noise pollution and destroys the quiet indoor environment. On the premise of meeting the normal emission of oil and fume, it is difficult for the existing flue to isolate the infiltration and conduction of oil, fume, heat and sound into the room, and improvements need to be made. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a flue structure arranged along the building exterior wall, which is separately and independently arranged from the building exterior wall to reduce the heat carried by the smoke itself from being conducted into the room through the wall, so as to achieve the purpose of optimizing the indoor environment.

[0005] The utility model discloses a flue structure arranged along the building exterior wall, which includes a flue main wall, an enclosing wall and a finished flue; a number of cantilever beams are formed on the outside of the building exterior wall, and each cantilever beam is longitudinally distributed along the building exterior wall; the flue main wall is arranged between two adjacent cantilever beams, so that a sealed gap layer is formed between the flue main wall, the cantilever beam and the building exterior wall; the enclosing wall is arranged on the side of the flue main wall away from the building exterior wall, and a civil engineering flue is formed by enclosing between the enclosing wall and the flue main wall, and the finished flue is arranged in the civil engineering flue.

[0006] Preferably, the enclosing wall is in a "C" shape, and the horizontal cross-section of the civil engineering flue formed between the enclosing wall and the flue main wall is rectangular.

[0007] Preferably, construction columns are arranged at the outer corners of the enclosing wall, and the construction columns are integrally connected to the building exterior wall through beams.

[0008] Preferably, heat insulation and sound insulation materials are arranged in the gap layer.

[0009] Preferably, the heat and sound insulation material is rock wool, mineral wool or glass wool.

[0010] Preferably, the thickness dimension of the main wall of the flue is set to L, and the thickness dimension of the gap layer is set to W.

[0011] Preferably, the thickness of the enclosure wall is the same as the thickness of the main wall of the flue; the spacing between the finished flue and the civil flue is set to H and meets the requirement of 8 cm. <H<12cm。

[0012] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0013] 1. A main flue wall is set outside the building's exterior wall to form a gap layer between the main flue wall and the building's exterior wall; a double wall is formed between the flue and the interior, which reduces the penetration or leakage of oil and smoke into the interior, and reduces the heat carried by the smoke itself from being conducted into the interior through the wall, so as to achieve the purpose of optimizing the indoor environment.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the following further details the present utility model in conjunction with the attached Figure 1-5 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] Referring to Figure 1 、 Figure 2 and Figure 3 , a flue structure arranged along the building exterior wall is provided outside the exterior wall beam 2. At the exterior wall beam 2 of each floor, a cantilever beam 3 is poured and extended outward. The height of the cantilever beam 3 is determined according to structural calculation. The cantilever beam 3 and the exterior wall beam 2 are integrally designed to ensure the structural stability of the cantilever beam 3. A main flue wall 4 is formed between the cantilever beams 3 of two adjacent floors. The outer side of the main flue wall 4 is flush with the end of the cantilever beam 3, so that a gap layer 7 is formed among the main flue wall 4, the cantilever beam 3 and the building exterior wall 1; a retaining wall 5 is arranged outside the main flue wall 4. The retaining wall 5 is in a "C" shape. The retaining wall 5 and the main flue wall 4 enclose each other to form a civil flue 6, so that the formed civil flue 6 is rectangular; in order to make the formed civil flue 6 have higher structural strength, construction columns 51 are arranged at the outer corners of the retaining wall 5. The construction columns 51 are connected to the exterior wall beam 2 or the cantilever beam 3 in the building exterior wall by beams to enhance the firmness of the civil flue 6; the main flue wall 4 and the building exterior wall 1 make a double wall formed between the constructed civil flue 6 and the interior. In addition, it is necessary to ensure that the main flue wall 4 is airtight and flat without reserved holes to prevent oil, smoke, heat and sound from penetrating and conducting into the interior, so as to form a good sound insulation and heat insulation effect.

[0023] Referring to Figure 4 and Figure 5 , in order to make the civil flue 6 and the interior have better sound insulation and heat insulation effects, heat insulation and sound insulation materials 8 are arranged between the main flue wall 4 and the building exterior wall 1. The heat insulation and sound insulation materials 8 are usually selected as rock wool, mineral wool or glass wool. Rock wool, mineral wool or glass wool all have extremely strong heat insulation performance and sound insulation performance, so as to isolate the heat and sound generated in the civil flue 6 and keep the interior in a good and comfortable environment. The thickness dimension of the formed main flue wall 4 is set as L, and the thickness dimension of the gap layer 7 formed among the main flue wall 4, the cantilever beam 3 and the building exterior wall 1 is set as W, and the relationship between the thickness dimension of the main flue wall 4 and the thickness dimension of the gap layer 7 satisfies L = 2W, so as to keep appropriate dimensions between the constructed main flue wall 4 and the heat insulation and sound insulation materials 8 in the gap layer 7.

[0024] Referring to Figure 2 and Figure 5, after the construction of the civil engineering flue 6 is completed, a finished flue 9 is provided inside the civil engineering flue 6. During the installation process of the finished flue 9, attention should be paid to preventing the installation components from penetrating the main wall 4 of the flue, which may lead to a decrease in the performance of the main wall 4 of the flue in isolating oil, smoke, heat, and sound, so as to further improve the sound insulation and heat insulation effects on the discharged oil fume. The thickness dimension of the enclosure wall 5 is the same as that of the main wall 4 of the flue, both being L. The finished flue 9 is installed into the civil engineering flue 6, so that a certain distance is maintained between the finished flue 9 and the civil engineering flue 6. The distance dimension between the finished flue 9 and the civil engineering flue 6 is set as H, and the distance dimension between the finished flue 9 and the civil engineering flue 6 satisfies 8 cm < H < 12 cm. Thus, the length dimension and width dimension of the finished flue 9 are relatively smaller than those of the civil engineering flue 6, which is convenient for installing the finished flue 9 into the civil engineering flue 6.

[0025] Since the larger the inner cavity dimension of the finished flue 9 is, the greater the amount of oil fume flowing through the finished flue 9 per unit time is. Therefore, the specific inner cavity dimension of the finished flue 9 is determined according to the required exhaust volume. The thickness dimension of the civil engineering flue is set to 20 cm, so that the civil engineering flue is set to an appropriate thickness dimension, which can ensure good heat insulation and sound insulation effects on the oil fume flowing through the finished flue 9, reduce the heat carried by the oil fume itself from conducting through the wall to the indoor environment, avoid the indoor environment from warming due to the influence of oil fume, and at the same time avoid the noise pollution generated by the high-speed flow of oil fume from damaging the quiet indoor environment.

[0026] The specific implementation principle of the embodiment of this application is as follows: When constructing the double-wall flue, a cantilever beam 3 is integrally constructed and set outward on the outer side of the outer wall beam 2. The height of the cantilever beam 3 is determined according to structural calculation, and the length of the cantilever beam 3 is set to 30 cm. A main wall 4 of the flue with a thickness of 20 cm is constructed along the outer end of the cantilever beam 3. The outer side of the main wall 4 of the flue is flush with the end of the cantilever beam 3, so that a 10-cm-thick void layer 7 is formed between the main wall 4 of the flue and the building exterior wall 1; in addition, an enclosure wall 5 in the shape of a "匚" is built on the outer side of the main wall 4 of the flue. The thickness dimension of the enclosure wall 5 is the same as that of the main wall 4 of the flue. A construction column 51 is provided at the outer corner of the enclosure wall 5 and is connected into one body with the cantilever beam 3 or the outer wall beam 2 in the building exterior wall, so that the constructed civil engineering flue 6 has relatively high structural strength.

[0027] The arrangement of the main flue wall 4 forms a double wall structure between the civil flue 6 and the room, reducing the risk of oil smoke infiltration and leakage into the room, so as to avoid the oil smoke causing odor in the room; and a heat insulation and sound insulation material 8 is arranged between the main flue wall 4 and the building exterior wall 1. The heat insulation and sound insulation material 8 is usually made of rock wool, mineral wool or glass wool to reduce the heat carried by the oil smoke itself and conduct it into the room through the wall, thereby avoiding the indoor environment from heating up due to the influence of oil smoke, and at the same time avoiding the noise pollution caused by the high-speed flow of oil smoke to destroy the quiet environment indoors. A finished flue 9 is installed in the civil flue 6 to form a double-layer flue, and the sealing of the flue is greatly enhanced.

[0028] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
