Description
Technical Field
[0001] The utility model relates to the technical field of flue construction, in particular to a smoke leakage-proof joint for connecting finished flues. Background Art
[0002] As an important structure in medium and high-rise buildings, the smoke exhaust duct can improve residential air quality, reduce kitchen fume pollution, and improve indoor hygiene quality. Compared with the on-site masonry flue, the finished flue has the advantages of fast construction speed, high construction efficiency, and guaranteed flue quality, and is widely used in construction projects.
[0003] However, during the installation of the finished flue, since the cross-sectional sizes of each section of the flue are the same and the connecting parts of the flue are not provided with structures such as tongues and grooves for connection, direct welding is often used to connect two adjacent sections of the finished flue. The connection quality cannot be guaranteed, and the technical level required for the installation of the flue is relatively high. This leads to the fact that there is often a large risk of smoke leakage at the docking and extension parts of the finished flue. If smoke leakage occurs in the flue during later use, it will not only require rework, but will also greatly reduce the comfort of the residence. Therefore, it is necessary to provide a smoke leakage-proof joint for connecting the finished flue, which can solve the problem of easy smoke leakage at the connection parts of the finished flue in the prior art. Summary of the invention

[0007] The accommodating cavity between the outer joint plate and the inner joint plate is an annular structure matching the cross section of the finished flue, and the cross-sectional width of the annular structure is consistent with the wall thickness of the finished flue, so that the connecting ends of two adjacent sections of the finished flue are matched and embedded in the accommodating cavity.
[0008] The height of the external joint plate is consistent with the height of the internal joint plate, and the height of the external joint plate and the internal joint plate is greater than the joint width of the two adjacent sections of the finished flue, so that the external joint plate extends to fit on the outer wall of the two adjacent sections of the finished flue, and the internal joint plate extends to fit on the inner wall of the two adjacent sections of the finished flue, and the external joint plate and the internal joint plate are connected to the two adjacent sections of the finished flue into a sealed whole by sealant.
[0009] The joints of the connecting plate and the two finished flue sections are located in the same plane, so that the connecting end faces of the two adjacent finished flue sections can respectively abut against the two surfaces of the connecting plate after being inserted into the accommodating cavity, and are sealed and bonded by the sealant.
[0010] The connecting plate is located at half the height of the outer joint plate and the inner joint plate.

The accommodating cavity formed between the external joint plate and the internal joint plate can provide positioning for the docking of the two adjacent sections of the finished flue, avoid the installation misalignment problem of the finished flue and the non-vertical problem of the entire finished flue structure, and ensure the reliable docking of the two adjacent sections of the finished flue in a convenient and efficient manner.
[0014] 2. The utility model is provided with a connecting plate, which divides the accommodating cavity into two cavities of the same size, so as to facilitate the plugging of the connecting ends of two adjacent sections of the finished flue, so that the joint parts of the two adjacent sections of the finished flue are stably stressed and the force transmission is reliable, which is beneficial to improving the integrity and structural stability of the entire finished flue structure.

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] Please see attached Figure 1 To Attachment Figure 4 A smoke leakage-proof joint for connecting a finished flue, comprising an external joint plate 1, an internal joint plate 2, a fixing rib 3 and a connecting plate 4; the external joint plate 1 is circumferentially arranged on the outer side of the internal joint plate 2, and the external joint plate 1 and the internal joint plate 2 are connected by the connecting plate 4, so that a receiving cavity for plugging in a connecting end of a finished flue (not shown in the figure) is formed between the external joint plate 1 and the internal joint plate 2, and the butt ends of two adjacent sections of the finished flue are sealed and butt-jointed in the receiving cavity; one end of the fixing rib 3 is fixedly arranged on the outer wall of the external joint plate 1, and the other end of the fixing rib 3 is fixedly connected to a building structure or other fixed structure.
[0026] An accommodating cavity is formed between the external joint plate 1 and the internal joint plate 2, which can provide plug-in positioning and connection fixation for the docking of two adjacent sections of the finished flue, reducing the misalignment and non-verticality problems during the installation of the finished flue. At the same time, the external joint plate 1 and the internal joint plate 2 wrap the joint parts of the two adjacent sections of the finished flue, without the need for welding or setting connecting tongues and grooves, thereby improving the docking of the two adjacent sections of the finished flue while ensuring that no smoke leakage occurs at the docking parts.
[0027] The fixing ribs 3 can be used for the connection between the anti-smoke leakage joint of the utility model and the building structure. The fixing ribs 3 can be pre-fixed on the outer wall of the external joint plate 1, or pre-embedded in the building structure, thereby forming a stable and reliable overlap between the external joint plate 1 and the building structure, ensuring the setting stability of the anti-smoke leakage joint, and further ensuring the structural stability of the entire flue.
[0028] The fixing ribs 3 are arranged according to actual needs. For example, when the finished flue is arranged to fit the surface of the building structure, the fixing ribs 3 may not be arranged. Figure 5 and attached Figure 6 When installing the fixing ribs 3, the number of the fixing ribs 3 can also be adaptively adjusted according to actual installation requirements.
[0029] Please see attached Figure 2 The accommodating cavity between the outer joint plate 1 and the inner joint plate 2 is an annular structure that matches the cross-section of the finished flue, and the cross-sectional width of the annular structure is consistent with the wall thickness of the finished flue, so that the connecting ends of two adjacent sections of the finished flue are matched and embedded in the accommodating cavity.
[0030] The shapes of the outer joint plate 1 and the inner joint plate 2 can be made according to the shape of the finished flue. Most flues in the prior art are flue structures with rectangular cross-sections. Accordingly, the outer joint plate 1 and the inner joint plate 2 are both rectangular structures. Thus, the outer joint plate 1 and the inner joint plate 2 can be respectively attached to the outer wall and the inner wall of the finished flue, forming a circumferential wrapping of the joints of two adjacent sections of the finished flue, which is conducive to improving the reliability, convenience and sealing of the connection between the two adjacent sections of the finished flue.
[0031] Compared with the traditional welding and docking method, the cavity positioning and plug-in method is more convenient and efficient to install, the construction process is simpler, and the sealing of the finished flue can be better guaranteed.
[0032] Please see attached Figure 3 and attached Figure 4 The height of the outer joint plate 1 is consistent with the height of the inner joint plate 2, and the height of the outer joint plate 1 and the inner joint plate 2 is greater than the joint width of the two adjacent sections of the finished flue, so that the outer joint plate 1 extends to fit on the outer wall of the two adjacent sections of the finished flue, and the inner joint plate 2 extends to fit on the inner wall of the two adjacent sections of the finished flue, and the outer joint plate 1 and the inner joint plate 2 are connected to the two adjacent sections of the finished flue into a sealed whole by sealant.
[0033] The height of the outer joint plate 1 and the inner joint plate 2 can be adaptively adjusted according to the joint width of the two adjacent finished flue sections, ensuring that the outer joint plate 1 and the inner joint plate 2 have a certain overlap width with the two adjacent finished flue sections (the overlap width is preferably not less than 8 cm), thereby extending the flue gas overflow path and achieving the effect of sealing and preventing smoke leakage. At the same time, the sealing of the butt ends of the outer joint plate 1 and the inner joint plate 2 with the two adjacent finished flue sections is further improved by the sealant, ensuring the sealing effect of the finished flue after installation.
[0034] The connection plate 4 and the joints of the two finished flue sections are located in the same plane, so that the connecting end faces of the two adjacent finished flue sections can respectively abut against the two faces of the connection plate 4 after being inserted into the accommodating cavity, and are sealed and bonded by the sealant.
[0035] The two surfaces of the connecting plate 4 abut against the connecting end surfaces of the two adjacent sections of the finished flue, with a large contact area. The connecting plate 4 forms a reliable force transmission between the two adjacent sections of the finished flue, and the connection stability of the two adjacent sections of the finished flue is high, so that the integrity and stability of the finished flue are better. The sealant is used to improve the connection firmness and sealing of the connecting end surface of the finished flue and the surface of the connecting plate 4, further improving the overall stability and sealing of the finished flue.
[0036] Please see attached Figure 3 and attached Figure 4 The connecting plate 4 is located at half the height of the outer joint plate 1 and the inner joint plate 2.
[0037] The connecting plate 4 divides the accommodating cavity into two cavities of the same size, thereby facilitating the plugging of the connecting ends of two adjacent sections of finished flue in the two cavities. The overlapping lengths of the two adjacent sections of finished flue and the anti-smoke leakage joint are the same, the force is evenly applied, and the plugging stability is high.
[0038] Please see attached Figure 4 The fixing ribs 3 are arranged symmetrically, and the fixing ribs 3 and the connecting plate 4 are located in the same plane.
[0039] The fixing ribs 3 and the connecting plate 4 are located in the same plane, forming a good force transmission effect between the flue and the building structure, thereby improving the structural stability of the entire finished flue and extending its service life.
[0040] Please see attached Figure 1 To Attachment Figure 6 , the manufacturing method of the utility model is:
[0041] According to the inner wall size and shape of the finished flue, an inner joint plate 2 of corresponding size and shape is made of steel plate; according to the outer wall size and shape of the finished flue, an outer joint plate 1 of corresponding size and shape is made of steel plate; according to the wall thickness and shape of the finished flue, a connecting plate 4 of corresponding size and shape is made of steel plate.
[0042] The outer joint plate 1 is placed outside the inner joint plate 2 , and the connecting plate 4 is welded between the outer joint plate 1 and the inner joint plate 2 . The connecting plate 4 is located at half the height of the outer joint plate 1 and the inner joint plate 2 .
[0043] The fixing ribs 3 are made of secondary steel bars with a diameter of ≥14 mm. The length of the fixing ribs 3 can be determined according to the distance between the flue and the fixing points on the building structure. One end of the fixing rib 3 is welded to the outer wall of the external joint plate 1, and the fixing rib 3 is located on the outside of the connecting plate 4. Four fixing ribs 3 can be symmetrically arranged and arranged symmetrically about the external joint plate 1.
[0044] Please see attached Figure 1 To Attachment Figure 6 The method of installing the finished flue using the smoke leakage-proof joint of the utility model is:
[0045] After the installation of the lower section of the finished flue is completed, inorganic high-temperature glue is evenly applied on the inner wall of the external joint plate 1, the outer wall of the internal joint plate 2, and the two surfaces of the connecting plate 4, and the lower part of the anti-smoke leakage joint is sleeved onto the upper end of the lower section of the finished flue. The upper end of the lower section of the finished flue is inserted into the accommodating cavity between the external joint plate 1 and the internal joint plate 2, and the upper end face of the lower section of the finished flue is attached to the bottom surface of the connecting plate 4.
[0046] The lower end of the upper finished flue is inserted into the accommodating cavity at the upper part of the anti-leakage joint of the utility model, and the lower end face of the upper finished flue is attached to the fixed surface of the connecting plate 4. The outer joint plate 1 is attached to the outer walls of the upper and lower finished flues, and the inner joint plate 2 is attached to the inner walls of the upper and lower finished flues, and is sealed and bonded by inorganic high-temperature glue to ensure that the upper and lower finished flues are connected into a sealed whole through the anti-leakage joint, which greatly reduces the risk of smoke leakage at the joint of the upper and lower finished flues.
[0047] The four fixing ribs 3 are fixed to the fixing points of the adjacent building structure to ensure the stability of the smoke leakage prevention joint of the utility model and the entire flue. All adjacent finished flues are connected in the same way until the installation of all sections of the finished flue is completed to form a complete finished flue structure, which will not be described one by one here.
[0048] For horizontal flues and oblique flues, the installation methods are the same, only the setting directions of the anti-smoke leakage joints are different. During installation, the axial direction of the anti-smoke leakage joint can be aligned with the axial direction of the flue. This is suitable for the docking of two adjacent sections of coaxially arranged finished flues without tongue and groove.
[0049] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
