[0002] Ventilation ducts are an important part of air circulation in buildings. Their design and installation directly affect indoor air quality and comfort. The main functions of ventilation ducts include: introducing fresh air into the room and exhausting dirty air; helping to adjust the indoor temperature and maintain a comfortable environment through the ventilation system; effectively controlling indoor humidity to prevent mold and other problems; and exhausting odors.
[0003] Ventilation ducts are widely used in residential buildings, commercial buildings, industrial plants, garages, warehouses, etc. Ventilation ducts are the core part of the building ventilation system. Through reasonable design and maintenance, they can greatly improve indoor air quality and comfort.
[0004] In the prior art, ventilation ducts of buildings, especially those in large-space buildings such as garages and warehouses, are mostly constructed by hanging iron ducts on the ceiling. The ducts are mostly exposed structures. In addition to the fire-fighting water pipes and monitoring and lighting pipelines, the entire ceiling looks messy and has a great impact on the visual effect. In addition, a rectangular iron duct is separately set at the bottom of the concrete trough, which requires the reserved height of the structural layer and the equipment layer, resulting in a small net height of the basement.

[0007] The technical solution adopted by the present invention to solve the technical problem further includes: The concrete beam adopts a precast concrete beam structure, or a composite beam structure consisting of precast concrete and cast-in-place concrete.
[0008] The concrete beam is provided with an opening, which is opened corresponding to the prefabricated concrete trough plate.
[0009] The bottom of the prefabricated concrete trough plate is embedded with a steel bar, and the edge of the sealing plate is welded to the steel bar by a welding process.
[0010] The concrete beam side is embedded with a steel bar, which is bent at the edge of the sealing plate to form an "L"-shaped bending edge, and the "L"-shaped bending edge is welded to the steel bar by a welding process.

[0012] The sealing plate is made of a bottom plate iron sheet, a fireproof rock wool board is arranged under the bottom plate iron sheet, and the fireproof rock wool board is fixedly installed with the bottom plate iron sheet through heat-insulating welding nails.
[0013] The edges of the sealing plates are bent to form a U-shaped joint, and the edges of the adjacent sealing plates are bent to form an L-shaped joint. The L-shaped joint is inserted into the "U" shape of the U-shaped joint and is fixedly connected by connecting nails.
[0014] The connecting nails are screws or rivets.

[0025] Please refer to the attached Figure 1 To Attachment Figure 6 The present invention mainly protects a building structure system without ventilation ducts, which mainly includes a concrete column 1, a concrete beam 2, a precast concrete trough 4 and a cover plate. The concrete beam 2 is arranged on the concrete column 1, the precast concrete trough 4 and the concrete beam 2 are installed together, and the cover plate is packaged at the bottom of the precast concrete trough 4, so that a closed ventilation duct is formed between the cover plate and the precast concrete trough 4, replacing the traditional iron air duct, and the equipment pipeline can also be arranged at an appropriate position inside the ventilation duct.
[0026] In this embodiment, the concrete beam 2 may adopt a precast concrete beam structure, or a composite beam structure composed of precast concrete and cast-in-place concrete. Preferably, an opening 3 is provided on the concrete beam 2, and the opening 3 corresponds to the opening of the precast concrete trough 4, or in other words, when the precast concrete trough 4 is installed, it is provided corresponding to the opening 3. When the concrete beam 2 adopts a precast concrete beam structure, the opening 3 is provided on the precast beam, and when the concrete beam 2 adopts a composite beam structure, the opening 3 may be provided in the cast-in-place concrete part. If the opening 3 is not provided, the ventilation ducts on both sides of the concrete beam 2 may be connected at the position of the concrete beam 2 through an iron air duct. Regardless of whether the concrete beam 2 is provided with an opening 3 or the iron air duct is used for connection, a ventilation system can be formed through the entire building.
[0027] In the present embodiment, a steel bar is embedded at the bottom of the precast concrete trough plate 4, and preferably, a pre-buried flat steel 6 is used. During the specific implementation, the steel bar can also be driven into the set position according to actual needs, and the edge of the sealing plate is welded together with the steel bar by welding technology to realize the installation of the sealing plate. In the present embodiment, a sealant 7 is provided at the edge of the sealing plate, and the sealant 7 is used to achieve the sealing between the edge of the sealing plate and the bottom of the precast concrete trough plate 4, so as to increase the air tightness of the pipeline.
[0028] In the present embodiment, a steel bar is embedded in the side of the concrete beam 2, and preferably a pre-buried flat steel 6 is used. During the specific implementation, the steel bar can also be driven into the set position according to actual needs, and the edge of the sealing plate is bent to form an "L"-shaped bending edge. The "L"-shaped bending edge is welded to the steel bar by a welding process to achieve the installation between the sealing plate and the concrete beam 2. In the present embodiment, a sealant 7 is provided on the edge of the sealing plate, and the sealant 7 is used to achieve the sealing between the edge of the sealing plate and the concrete beam 2, so as to increase the air tightness of the pipeline.
[0029] In this embodiment, the sealing plate is preferably made of iron sheet to form a bottom plate iron sheet 5. A fireproof rock wool board 9 is arranged under the bottom plate iron sheet 5. The fireproof rock wool board 9 is fixedly installed with the bottom plate iron sheet 5 by thermal insulation welding nails 10 to ensure the fire resistance of the iron sheet. In specific implementation, when fire prevention or thermal insulation is not required, the fireproof rock wool board 9 may not be arranged. The installation method of the fireproof rock wool board 9 may also adopt other conventional fixed installation methods, such as: gluing, etc., which will not be repeated here.
[0030] In this embodiment, the precast concrete trough 4 is relatively long, and one bottom plate iron sheet 5 is not sufficient to cover the entire precast concrete trough 4, so it is necessary to splice two or more bottom plate iron sheets 5 to achieve longitudinal extension of the bottom plate iron sheet 5, and there are longitudinal joints 8 of the iron sheets, wherein one bottom plate iron sheet 5 is bent at its edge to form a U-shaped joint 11, and another bottom plate iron sheet 5 is bent at its edge to form an L-shaped joint 12, and the L-shaped joint 12 is inserted into the "U"-shaped interior of the U-shaped joint 11, and is fixedly connected by connecting nails 13. In specific implementation, the connecting nails 13 can be screws or rivets, or other connecting structures.
[0031] The present invention uses a sealing plate to seal the bottom of the precast concrete trough plate, and uses the sealing plate to combine with the internal space of the precast concrete trough plate to form a ventilation duct, so that the entire ceiling has better integrity and is more beautiful. The present invention combines the structural layer and the equipment layer, and uses the concrete trough plate structure as a ventilation duct, which compresses the height of the ventilation duct layer, increases the net height of the basement, or reduces the overall height of the basement.
