The reinforcing wings are arranged along the height direction of each flat plate, and a through space for filling with sealing material is formed between the reinforcing wings and the wall. However, such a method as the above has the problem of difficulty in making the reinforcing wings on the one hand, and the problem of inconvenient installation on the other hand. In addition, when the thin-walled structure is hit by an external force, it is easy to cause cracks at the joints, resulting in reduced sealing performance and frequent smoke and odor leakage. Therefore, further improvements are needed. Utility Model Content

[0024] In the following description, many specific details are explained in combination with the embodiments to facilitate a full understanding of the present invention. However, it should be understood that the following embodiments and detailed descriptions are only for illustrative purposes and do not limit the scope of protection of the present invention.

[0025] The cross-sectional shape of the thin-walled member 10 for the exhaust duct of the present invention can be L-shaped, U-shaped, or other shapes such as a bent plate at a predetermined angle.

[0026] like Figure 1 As shown, the assembly structure of the thin-walled component 10 for the exhaust duct of Example 1 includes two positioning sealing corner guards 20 and a plurality of fixing parts 30; wherein, the positioning sealing corner guards 20 are used to connect the thin-walled component 10 to the wall 40 and combine with the wall 40 to form the exhaust duct a, and the fixing parts 30 are used to realize the connection between the positioning sealing corner guards 20 and the wall 40, and the positioning sealing corner guards 20 and the thin-walled component 10.

[0027] Furthermore, the positioning sealing corner guard 20 has a first connecting edge portion 21 and a second connecting edge portion 22 that are perpendicular to each other. The positioning sealing corner guard 20 is installed on the wall 40 by a fixing piece 30 that passes through the first connecting edge portion 21, and the open edge portion 11 of the thin-walled component 10 is installed on the positioning sealing corner guard 20 by a fixing piece 30 that passes through itself and passes through or penetrates into the second connecting edge portion 22, so that the thin-walled component 10 is installed on the wall 40 and combined with the wall 40 to form an exhaust duct a.

[0028] The positioning and sealing corner guard 20 in the embodiment preferably uses a mortar-made corner guard connector. Specifically, the mortar is cement mortar with relatively good crack resistance. In other embodiments, metal corner guard connectors such as angle steel may also be used. The positioning and sealing corner guard 20 is in an elongated strip shape, and its cross-section may be square, L-shaped, or triangular. It may also be a polygon, a regular polygon, or other irregular shapes. The embodiment will be described using an L-shaped positioning and sealing corner guard 20 as an example.

[0029] Specifically, the positioning sealing corner guard plate 20 includes a first flat plate 20a and a second flat plate 20b that are perpendicular to each other. The outer surface of the first flat plate 20a provides a first connecting edge portion 21, and the outer surface of the second flat plate 20ba provides a second connecting edge portion 22; wherein, the width of the first flat plate 20a and the width of the second flat plate 20b can be the same or different, and can be adaptively selected according to specific needs.

[0030] During installation, first apply adhesive (such as building sealant such as tile adhesive) on the outer surface of the first connecting edge 21, and then adhere the positioning sealing corner guard 20 to the wall 40 along the installation position of the thin-walled component 10; then, fix the positioning sealing corner guard 20 to the wall 40 through a plurality of upper and lower spaced fixing parts 30; after the positioning sealing corner guard 20 is fixed, apply adhesive on the outer surface of the second connecting edge 22, and adhere the two open edge parts 11 of the thin-walled component 10 to the second connecting edge parts 22 of the two positioning sealing corner guards 20 respectively, and form a rectangular exhaust duct between the thin-walled component 10 and the wall 40; then, fix the thin-walled component 10 to the positioning sealing corner guard 20 through a plurality of upper and lower spaced fixing parts 30 to complete the assembly between the thin-walled component 10 and the wall 40.

[0031] Among them, a protective net 50 can also be attached to the seam. The protective net 50 is specifically an alkali-resistant glass fiber mesh cloth. The alkali-resistant glass fiber mesh cloth is Figure 1 The left and right directions and the up and down directions are preferably about 100 mm, which can better protect the polymer mortar at the joints and improve the connection strength at the joints.

[0032] As a variation of the above embodiment 1, Figure 2 As shown, the thin-walled component 10 in the assembly structure embodiment 2 also includes a connecting plate 12, which is arranged on the side of the open edge portion 11 of the thin-walled component 10 facing the wall 40 and specifically protrudes outward; correspondingly, a plug-in groove is provided on the wall 40, and the plug-in groove can be a slit groove obtained by on-site construction. When the thin-walled component 10 is installed in place, the connecting plate 12 extends into the plug-in groove.

[0033] As another variation of the above embodiment 1, Figure 3 As shown, in order to accommodate more adhesive and polymer mortar at the joint, the open edge portion 11 of the thin-walled component 10 in Example 3 has an inclined outer side surface 11a, which can further prevent the polymer mortar filled in the joint from detaching, and help to form a better sealing effect.

[0034] Furthermore, as an extension of Examples 2 and 3, Figure 4 As shown, in Example 4, the open edge portion 11 of the thin-walled component 10 is also provided with a protruding connecting plate 12 on the side facing the wall 40, and the fixing member 30 passes through the connecting plate 12 and passes through or penetrates into the second connecting edge portion 22 to connect the thin-walled component 10 and the positioning sealing corner plate 20 together.

[0035] In order to better realize the installation of the positioning sealing corner plate 20, Figure 5 In the fifth embodiment shown, a recessed receiving groove 41 is provided on the wall 40 corresponding to the first connecting edge 21. The first connecting edge 21 is at least partially embedded in the receiving groove 41. Preferably, the first connecting edge 21 is completely embedded in the receiving groove 41, thereby achieving a more stable connection. The receiving groove 41 is filled with sealing mortar, thereby further facilitating a better sealing effect.

[0036] The groove width of the receiving groove 41 in Example 5 is relatively large, which is beneficial to the installation of the first connecting edge portion 21 on the one hand, and can also accommodate more sealing mortar on the other hand; wherein, the open edge portion 11 of the thin-walled member 10 is specifically configured not to extend into the receiving groove 41, so that the sealing mortar accommodated in the receiving groove 41 can be sealed in the receiving groove 41 by the side of the open edge portion 11 and will not overflow.

[0037] In an optional embodiment, the open edge 11 of the thin-walled member 10 can also be configured to extend into the receiving groove 41, and the open edge 11 of the thin-walled member 10 can be wrapped and sealed with a sealing mortar. Accordingly, an alkali-resistant glass fiber mesh is preferably attached to the joint for protection.

[0038] As another extension of the above embodiment, Figure 6As shown, the outer surface of the positioning sealing corner guard 20 in Example 6 is provided with a notch portion 23 at the connection between the first connecting edge portion 21 and the second connecting edge portion 22. During installation, the open edge portion 11 of the thin-walled component 10 at least partially covers the notch portion 23 to form a dovetail groove structure with a larger inner portion and a smaller outer portion between the wall 40, the positioning sealing corner guard 20 and the thin-walled component 10. The dovetail groove structure is filled with an adhesive such as polymer mortar. Compared with the traditional sealing method of plastering the gap, the dovetail groove structure can help prevent the polymer mortar from falling off, thereby improving the sealing effect at the joint.
