High-strength gas flue

Abstract

The invention discloses a high-strength gas flue, which is formed by assembling four lateral plates, wherein the cross section of the gas flue is rectangular, and four corners on the inner side of the gas flue are provided with strengthening ribs connected with adjacent lateral plates. The high-strength gas flue has the following remarkable advantages that: 1, the weight is light, a gas flue of three meters in length has only about 70 kilograms which is less than one fourth of the weight of the prior product with the same size, thus the transportation and the assembly are very convenient; 2, the vertical bearing capacity of each gas flue reaches up to 15 to 16 tons; 3, too many production moulds and production sites are not needed, the manufacture is very convenient, the yield is high, and the gas flue is suitable for mass production; and 4, the cost is low.

Description

technical field [0001] The invention relates to an accessory in buildings such as residences, apartments, and office buildings, in particular to a high-strength flue gas channel for removing smoke or waste gas in the building. Background technique [0002] The flue gas duct is used to remove the smoke or exhaust gas from the kitchen and bathroom, and almost all buildings have flue gas exhaust ducts. The existing flue gas exhaust duct is basically formed by laying and cutting ordinary cement materials on site or pouring with cement, or prefabricated. Among them, on-site masonry and cutting is a relatively traditional method. With the modernization and standardization of construction technology, this method is basically no longer used. The more commonly used method is prefabrication, that is, according to the requirements of different buildings, prefabrication Make flue gas ducts of different specifications and models, and then transport the flue gas ducts to the site for ins...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. Because there are many specifications and models of the flue gas duct, a large number of production molds need to be made; 2. A large production site is required at the production site of the prefabricated flue gas duct; 3. Since the flue gas duct is mainly It is made of cement yellow sand material, so the weight of the finished product is relatively large. A three-meter-long flue gas channel weighs about 300 kilograms, and its installation and transportation are extremely inconvenient; It is easily damaged during the process, and its strength is difficult to meet the national industry standard; 5. The vertical bearing pressure is only 7-8 tons; 6. The production efficiency is low, and it is difficult to form mass production; 6. Due to the rough inner surface, it is easy to The deposition of oil will affect the effect of exhaust gas, and even cause fire; 7. It is difficult to maintain the flue gas channel
