Description

Technical Field

[0001] The invention relates to the technical field of building flue construction, in particular to a construction method for a flue with reserved tongue-and-groove hanging-free holes. Background Art

[0002] With the rapid development of housing construction and the development of the fourth generation of buildings in my country, people have extremely high requirements for the quality, appearance and comfort of housing, and they pay special attention to the details of the houses delivered in rough form. In the construction of the flue system of civil construction projects, the flue plays the main function of kitchen smoke exhaust or bathroom ventilation, so it is a widely used system in civil buildings. Among them, the flue is a thin-walled structure, and the installation hole needs to be reserved in advance as a secondary installation building component.

[0003] The construction of hanging holes at the flue outlets of kitchens and bathrooms is extremely difficult. The hanging holes are generally made of wire or formwork is supported on the top plate of the lower flue. The space is small and cannot be vibrated or the vibration is not dense, which often leads to leakage or honeycombed surface quality problems, requiring secondary repairs, which greatly increases the construction cost.

[0004] Patent CN114892975A discloses an installation mold and construction method of a building flue system, in which a shaping mold is reserved at the flue hole, a convex ridge is formed at the flue hole, and the prefabricated flue is directly installed on the convex ridge, which is used to support the weight of the flue and speed up the installation efficiency. However, in this patent, convex ridges are set on all four sides of the flue hole, which is difficult to implement in actual scenarios, especially in buildings where the flue is set at the corner of the wall. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a flue reserved tongue and groove construction method without hanging holes. When designing the aluminum mold, a groove boss is reserved to achieve a construction process without hanging holes, so that the flue is placed on the boss to unload the load layer by layer, which changes the traditional flue unloading method of setting angle irons at no more than two layers of the flue mouth, and placing the flue on the angle irons for unloading. At the same time, the effect of anti-leakage is achieved, the main structure construction stage is completed once, the construction quality and effect are good, the purpose of reducing costs and increasing efficiency is achieved, the construction period is saved, and the labor and material costs are saved.

[0006] To achieve this technical purpose, the present invention adopts the following scheme: A construction method for a flue reserved tongue-and-groove hanging-free hole comprises the following steps: S1. According to the specific dimensions of the flue in the architectural drawing, the flue tongue and groove are further designed, and a boss is set at the flue tongue and groove position; S2. Design a special template for flue tongue and groove boss shaping; S3. During the main construction, steel bars shall be reserved at the flue groove position; S4. After the main construction is completed, the boss template is installed at the flue groove position and concrete is poured; S5. After the concrete strength of the boss reaches the requirement, remove the formwork and install the flue.

[0007] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a flue reserved tongue and groove free hanging hole construction method. When designing the aluminum mold, a groove boss is reserved to achieve a construction process free of hanging holes, so that the flue is placed on the boss to unload the load layer by layer, which changes the traditional flue unloading method of setting angle irons at no more than two layers of the flue mouth, and placing the flue on the angle irons for unloading. At the same time, the effect of anti-leakage is achieved, the main structure construction stage is completed once, the construction quality and effect are good, the purpose of reducing costs and increasing efficiency is achieved, the construction period is saved, and the labor cost and material cost are saved.

[0008] Furthermore, the specific dimensions of the flue in the building drawing are A*B, and the floor thickness is H; The size of the flue groove upper opening is further designed to be (A+a)*(B+a)*h1; The size of the flue groove bottom is further designed to be (A+a)*(B+a)*h2; The hole size of the middle boss of the flue groove is further designed to be (Aa)*(Ba)*h3, where h3=H-h1-h2.

[0009] Furthermore, a is 25-30 mm, h1 is 15-25 mm, and h2 is 35-45 mm.

[0010] Furthermore, when installing the flue, the flue is inserted into the groove at the lower end of the top plate flue tongue and groove, the flue is against the bottom of the boss, and then slowly placed in the groove at the upper end of the bottom plate flue tongue and groove. At this time, the flue just falls on the boss of the bottom plate flue tongue and groove, and finally the area around the flue is sealed with waterproof mortar.

[0011] Furthermore, the boss is arranged on a side of the flue groove close to the floor slab. BRIEF DESCRIPTION OF THE DRAWINGS
