[0001] The utility model relates to the technical field of ventilation facilities, in particular to a fire safety smoke exhaust duct. Background Art

[0002] Fire safety smoke exhaust ducts are usually made of high-temperature resistant materials and designed with appropriate thickness and fire resistance limit to meet different levels of fire protection requirements. At the same time, correct design, construction, maintenance and management are crucial for improving the efficiency and reliability of the fire smoke exhaust system. In addition, popularizing fire safety knowledge and strengthening safety management in special areas such as kitchens are also important measures to prevent fires. The main function of the fire safety smoke exhaust duct is to effectively exhaust smoke and toxic gases in case of a fire to ensure the safe evacuation of personnel and the smooth progress of fire fighting operations; such a smoke exhaust duct can minimize casualties and property losses in a fire and provide valuable time for escape and rescue in an emergency. In the existing residential smoke exhaust technology, vertical smoke exhaust ducts are usually used for residential smoke exhaust; the smoke exhaust duct mainly consists of a main smoke exhaust duct and its corresponding accessories, and its basic structure is mainly composed of assembled cement mortar components. The structure of this kind of smoke exhaust duct is relatively complex, with many production processes and high manufacturing requirements, resulting in high production costs; due to the need to use installation parts for combined connection, to ensure safety and reliability, the thickness of the main board body of the flue is large, which requires more raw materials and also increases the manufacturing cost; moreover, because splicing is required between components for sealing treatment, when the sealing is improper or after long-term use, air leakage will occur, which not only affects the use of each household in the entire flue, but may also cause safety accidents such as fires.

The fastening mechanism includes two C-shaped strips 110 and a buffer pad 111. Through the foregoing solution, the technical problem that the pipe body in the above structure is integrally formed, resulting in a relatively large volume, occupying too much space during transportation, and thus increasing the transportation cost is solved.

[0023] For this specific embodiment, dovetail blocks 103 are provided on both sides of the side block 101, and a smoke inlet hole 104 is provided on one of the side blocks 101. Two dovetail grooves 105 are provided on the outer side of the connecting block 102. A plurality of the side blocks 101 and a plurality of the connecting blocks 102 are respectively connected in a surrounding shape, and the dovetail block 103 is located in the corresponding dovetail groove 105. By providing the dovetail groove 105 and the dovetail block 103, a plurality of the side blocks 101 and a plurality of the connecting blocks 102 can be spliced into a surrounding smoke exhaust duct. This structure can avoid occupying too much space during transportation, thereby reducing the transportation cost, and the assembly method of this structure has the advantages of simplicity and convenience.

By adopting the non-combustible property of the alkali-resistant fiberglass mesh cloth 106, the fire safety is increased, so as to ensure the improvement of safety protection during smoke exhaust.

[0025] Secondly, the anti-disengagement ring 108 is fixedly connected to the corresponding side block 101 by bolts, and the anti-disengagement ring 108 also abuts against the corresponding side block 101 and is located at one end of a plurality of the side blocks 101. By means of the anti-disengagement ring 108, the stability of a plurality of the side blocks 101 and a plurality of the connecting blocks 102 after splicing can be conveniently improved.

[0026] Thirdly, a plurality of positioning rods 109 are provided on the end face of the anti-disengagement ring 108, and a plurality of the positioning rods 109 are respectively inserted into the corresponding connecting blocks 102 and are located at one end of the connecting blocks 102.

[0027] In addition, the two C-shaped strips 110 are respectively fixedly connected by bolts and are symmetrically arranged, and the two C-shaped strips 110 also respectively abut against the corresponding side blocks 101 and are sleeved on the outer walls of a plurality of the side blocks 101. By providing the two C-shaped strips 110, the sealing performance between a plurality of the side blocks 101 and a plurality of the connecting blocks 102 can be conveniently improved, so as to avoid leakage during smoke exhaust.

[0028] Meanwhile, the buffer pad 111 abuts against the corresponding C-shaped strip 110 and is symmetrically arranged at the connection of the two C-shaped strips 110. The buffer pad 111 facilitates continuously increasing the tightness between the two C-shaped strips 110 under the action of bolts and nuts, and at the same time avoids wear caused by the contact between the two C-shaped strips 110.

[0029] When the present utility model is in use, by splicing a plurality of the side blocks 101 and a plurality of the connecting blocks 102 in an enclosed shape, and at the same time sliding the dovetail block 103 into the dovetail groove 105, a plurality of the side blocks 101 and a plurality of the connecting blocks 102 form a smoke exhaust duct. Then, the anti-detachment ring 108 is abutted against one end of a plurality of the side blocks 101 and a plurality of the connecting blocks 102 and fixed by bolts. Finally, a plurality of the fastening mechanisms are sleeved on the smoke exhaust duct formed by a plurality of the side blocks 101 and a plurality of the connecting blocks 102, and the two C-shaped strips 110 play a role in fastening the smoke exhaust duct through bolts. In this way, the technical problem in the above structure that the pipe main body is integrally formed, resulting in a relatively large volume and occupying too much space during transportation, thereby increasing the transportation cost, is solved.
