Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction method of a public horizontal flue. Background Art

[0002] In residential projects, commercial facilities are often set up around the residences. Some of the commercial facilities are used for catering. When used for catering, cast-in-place public horizontal flues are usually installed on the roof.

[0003] The cast-in-place public horizontal flue is completely enclosed. The internal formwork support frame cannot be removed during the construction of the flue top plate. If it is left inside without removal, it will affect the ventilation performance of the flue. In addition, if the formwork is not removed, the formwork is a flammable material, and if it is left inside the flue, there will be a fire safety hazard. If the hanging formwork is used for construction, the formwork cannot be removed, which will cause a fire safety hazard. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a construction method for a public horizontal flue to solve the problem that the template is inconvenient to remove after the existing flue top plate is supported by a template and there are potential fire safety hazards.

[0005] The technical solution to achieve the above purpose is: a construction method of a public horizontal flue, comprising the following steps: constructing walls on both sides of the flue on the roof; pre-embedding multiple angle steels on the walls on both sides; and laying a cover plate above the angle steel between the walls on both sides.

[0006] In a construction method for a public horizontal flue of the present invention, the top plate of the horizontal flue is changed from cast-in-place to prefabricated and installed later, and the cover plate is supported by angle steel, thereby solving the problem that the internal formwork frame of the cast-in-place method cannot be disassembled, ensuring the use effect of the flue and avoiding fire safety hazards.

[0007] A further improvement of the construction method of a public horizontal flue of the present invention is that the pre-embedding of a plurality of angle steels on the walls on both sides comprises: arranging the angle steels on the inner side walls of the walls.

[0008] A further improvement of the construction method of a public horizontal flue of the present invention is that the pre-embedding of a plurality of angle steels on the walls on both sides also includes: arranging the angle steels on the walls on both sides relatively.

[0009] A further improvement of the construction method of a public horizontal flue of the present invention is that the pre-embedding of a plurality of angle steels on the walls on both sides also includes: welding anchor bars on the angle steels and embedding the anchor bars in the walls.

[0010] A further improvement of the construction method of a public horizontal flue of the present invention is that laying a cover plate above the angle steel between the walls on both sides includes: forming the cover plate by splicing a plurality of cover plate units.

[0011] A further improvement of the construction method of a public horizontal flue of the present invention is that laying the cover plate above the angle steel between the walls on both sides also includes: placing the two side ends of the cover plate unit on the angle steel.

[0012] A further improvement of the construction method of a public horizontal flue of the present invention is that laying the cover plate above the angle steel between the walls on both sides also includes: caulking the joints of adjacent cover plate units.

[0013] A further improvement of the construction method of a public horizontal flue of the present invention is that it further comprises: injecting a filling body into the gap between the cover plate and the wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Execute step S140: inject a filler 15 into the gap between the cover plate 13 and the wall 11 .

[0054] The size setting of the cover plate 13 during prefabrication needs to reserve a 10 mm gap with both sides of the wall 11 of the horizontal flue 10 to facilitate the installation of the cover plate 13. After the cover plate 13 reaches a certain strength, it is installed on the angle steel 12.

[0055] In this embodiment, the size of the gap can be changed according to the actual construction, and the filler 15 can be asphalt or other solidifiable materials, which can be selected according to actual needs and construction costs, and is not specifically limited here.
