Leakage-proof smoke flue butt joint structure

Abstract

A novel leak-proof flue connection structure features an insert frame composed of four welded side panels. The upper part of the four side panels forms an upper railing, and the lower part forms a lower railing. A connecting boss is provided between the upper and lower railings. The upper and lower flues are respectively inserted into the upper and lower railings. The connecting boss connects to the joint of the upper and lower flues. The upper and lower flues, along with the upper and lower railings and connecting boss of the insert frame, together constitute the leak-proof flue connection structure. This novel leak-proof flue connection structure is rationally designed; two flue sections are simply inserted into the insert frame. The insert frame transforms the traditional unrestrained flat-mouth flue connection into a restrained connection, eliminating installation displacement, reducing the connection gap, and making the connection more reliable. No multiple people are needed for adjustment during installation, saving 50% of construction costs. This novel leak-proof flue connection structure improves construction efficiency and ensures installation quality. The probability of flue leakage is zero, avoiding the risk of future leakage and maintenance, achieving the goal of green environmental protection.

Description

Technical Field

[0001] This utility model relates to a physical connection device, and in particular to a smoke-proof flue connection structure. Background Technology

[0002] Flues are an indispensable component of residential buildings. A complete flue system consists of several unit flue sections stacked and connected from bottom to top. Typically, the joint between two flue sections is located at the floor slab. The alignment of the joint cannot be measured with tools and can only be visually assessed, making it prone to displacement. This displacement directly determines the amount of smoke leakage. After installation, there is generally a 5mm gap between the joints, which contributes to a 15%–20% leakage rate. Even with cement mortar or flame-retardant sealing rings at the joints, these methods cannot completely eliminate the leakage caused by displacement or aging of the sealing rings. Later, when leaks occur, repairs are difficult and costly. Furthermore, the stacking method for installing flues is slow, requires many personnel for connection and adjustment, is time-consuming and labor-intensive, and results in high construction costs. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of traditional flue connection interfaces, such as easy displacement and structural gaps, by providing a simple, convenient, and quick flue installation that allows for easy alignment of the interface without adjustment, saving time and effort, with a virtually zero smoke leakage rate, and significantly reducing construction and maintenance costs.

[0004] The purpose of this utility model can be achieved. This utility model's leak-proof flue connection structure includes adjacent upper and lower flues. The feature of this leak-proof flue connection structure is: a rectangular frame-shaped insertion frame is provided, which is composed of four diagonally welded side panels. The upper part of the four side panels encloses to form an upper railing, and the lower part encloses to form a lower railing. A docking protrusion is provided within the frame between the upper and lower railings. The inner diameter of the upper and lower railings of the insertion frame is larger than the outer diameter of the flue. The bottom of the upper flue is inserted into the upper railing, and the bottom end of the upper flue rests on the docking protrusion. The top of the lower flue is inserted into the lower railing, and the bottom of the docking protrusion rests on the top of the lower flue. The upper and lower flues, the insertion frame, and the upper, docking protrusions, and lower railings together constitute the leak-proof flue connection structure.

[0005] This utility model relates to a smoke-proof flue connection structure, wherein the frame is made of 1.5mm galvanized steel sheet by molding. A U-shaped groove is molded on the longitudinal center of the outer side of the frame. The galvanized steel sheet above the groove is molded into an upper panel, and the galvanized steel sheet below the groove is molded into a lower panel. The inner side of the frame is recessed through the groove to form a longitudinally protruding strip.

[0006] This utility model relates to a smoke-proof flue connection structure, wherein the upper railing is formed by the upper railing of the four sides, the lower railing is formed by the lower railing of the four sides, and the connection boss is formed by the inner protruding strips of the four sides.

[0007] The present invention relates to a leak-proof flue connection structure, wherein the upper surrounding plate is 30±1mm high, the lower surrounding plate is 30±1mm high, and the inner protruding strip is 10+1mm high and 15±1mm long.

[0008] The present invention relates to a leak-proof flue connection structure, wherein the inner diameter of the upper and lower railings of the plug-in frame and the outer diameter of the flue are provided with a gap of about 5mm at each point, and the gap is filled with mortar to form a secondary sealing structure.

[0009] This utility model's leak-proof flue connection structure differs from existing technologies in that it features an insertion frame composed of four welded side panels. The upper part of the four side panels forms an upper railing, and the lower part forms a lower railing. A docking protrusion is provided between the upper and lower railings of the insertion frame. The upper and lower flues are respectively inserted into the upper and lower railings. The docking protrusion connects to the joints of the upper and lower flues. The upper and lower flues, along with the upper and lower railings and docking protrusion of the insertion frame, together constitute the leak-proof flue connection structure. This utility model's leak-proof flue connection structure simply requires inserting two flue sections into the insertion frame. The insertion frame transforms the traditional unconstrained flat-mouth flue connection into a constrained connection, eliminating displacement at the installation location, reducing the connection gap, and making the connection more reliable. No multiple people are needed for adjustment during installation, saving 50% of construction costs. This utility model's leak-proof flue connection structure improves construction efficiency and ensures installation quality. After testing, the probability of flue leakage is zero, avoiding the risk of future leakage and achieving the goal of green environmental protection.
