[0024] The following is in conjunction with the appendix Figs. 1-2 The specific implementation of the modular ventilated floor of this utility model will be described in further detail.

[0025] A modular ventilated floor, such as Fig. 1 As shown, the entire system consists of three main parts. The sunken floor slab 3 is an existing part of the building itself and needs to be designed in advance to allow for a sunken space. A frame support system 2 is arranged on the sunken floor slab 3, and a ventilated floor unit module 1 is laid on the frame support system 2.

[0026] In the above system, the sunken floor slab 3 is typically a reinforced concrete slab, which should be in close contact with the building walls it is connected to, and should have no other openings except for the pipe opening reserved for connection with the outdoor air conditioning unit. The sunken floor slab 3 should have good thermal insulation treatment to reduce changes in supply air temperature and reduce air conditioning energy loss.

[0027] The frame support system 2 is arranged on the upper surface of the sunken floor slab 3. It is made of metal square steel tubes or angle steel and other materials, and mainly serves a supporting function. The frame support system 2 forms a static pressure box between the ventilated floor unit module 1 and the sunken floor slab 3. The air conditioning system delivers the treated air to the static pressure box through pipes, and then enters the room through the ventilated floor unit module 1.

[0028] The ventilated floor unit module 1 is arranged on the frame support system 2 and is the floor slab that people directly come into contact with indoors. It has a hollow structure in the middle, which mainly serves to conceal air outlets and bear indoor loads. It is the smallest unit module of the entire ventilated floor.

[0029] The floor ventilation system can be made into a whole-ground ventilation system using ventilation floor unit module 1, or it can be made into a local ground ventilation system using ventilation floor unit module 1.

[0030] When not used as an indoor floor vent, the ventilated floor unit module 1 can be made into a fully enclosed structure.

[0031] Fig. 2 This is a disassembled schematic diagram of the ventilated floor unit module 1 of this utility model. The ventilated floor unit module 1 consists of a filling layer 4, a wire mesh 5, a reinforcing mesh 6, and a unit frame 7.

[0032] The filling layer 4 is located above the ventilated floor unit module 1. The main materials that can be used include gravel, stone, and wood. It must be breathable, aesthetically pleasing, non-toxic, harmless, and odorless, meeting building usage requirements. When using gravel, it is recommended to use 10-20mm diameter bonded stone, which has good strength and breathability, and its overall performance is relatively balanced, meeting daily use requirements. When using stone, holes can be evenly drilled on the surface for ventilation, or mortar can be laid in the middle, with the surface covered with floor tiles or stone to act as a non-ventilated floor tile. When using wood, it is recommended to use corrosion-resistant and non-deformable hard wood, leaving a 5-10mm gap in the middle for ventilation.

[0033] The wire mesh 5 is located below the infill layer 4. It is machine-woven from stainless steel wire with a diameter of approximately 1mm. The mesh size is selected based on the infill layer 4. The main function of the wire mesh 5 is to evenly bear the self-weight of the infill layer 4 and the load from above, and to transfer the load to the reinforcing mesh 6. During the construction of the infill layer 4, the wire mesh 5 also serves as a bottom formwork. The wire mesh 5 can also be placed between two layers of reinforcing bars in the reinforcing mesh 6.

[0034] The reinforcing mesh 6 is located below the wire mesh 5. It is made of ordinary steel bars of 8-10mm evenly welded onto the unit frame 7. The spacing between the steel bars is generally 50-150mm, preferably 100mm. Its main function is to bear tensile force, converting the load from the upper part into the tensile force of the steel bars, and then transferring it to the unit frame 7.

[0035] The unit frame 7 is made of metal angle steel, and it is recommended to use corrosion-resistant materials such as 304 stainless steel or hot-dip galvanized angle steel. It is the outer frame of the ventilated floor unit module 1, and opening holes for lifting can be set at the four corners. The unit frame 7 acts as a side formwork during the construction of the infill layer 4, and also works with the steel mesh 6 to provide strength, and transfers the upper load to the frame support system 2 and then to the sunken floor slab 3.

[0036] The ventilation floor unit module 1 provides higher bending load resistance by the cooperation of the filling layer 4, the steel wire mesh 5, the steel bar mesh 6 and the unit frame 7, solves the structural strength problem, solves the floor ventilation problem, meets the performance requirement of floor air supply of residential buildings and public buildings, and expands the applicable range of floor air supply forms of air conditioning systems.

[0037] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
