[0025] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0026] Example 1

[0027] refer to Figure 1, Figure 2 and Figure 3 As shown, a prefabricated component for connecting floors of an exhaust duct includes a lower support 1, an upper support seat 2, an air duct 3, reserved steel bars 4, truss steel bars 5 and a socket 6.

[0028] The lower pedestal 1 is a reinforced concrete structure, and the (horizontal) cross-section of the lower pedestal 1 is a rectangle. The plate-like shape formed by the lower pedestal 1 has a function similar to that of a prefabricated composite slab, and can be connected with other prefabricated composite slabs by binding and pouring to finally form an integral floor slab.

[0029] An upper bearing seat 2 is erected on the lower bearing platform 1. The upper bearing seat 2 is a reinforced concrete structure, and the lower bearing platform 1 and the upper bearing seat 2 are cast as one piece. The (horizontal) cross-section of the upper bearing seat 2 is a rectangle with chamfers at the four corners. The integrated structure of the upper bearing seat 2 is used to directly avoid the problems caused by the gap between the floor slab and the exhaust duct.

[0030] The cross-sectional profile of the lower pedestal 1 is larger than that of the upper pedestal 2, which meets the requirement of large floor slab and small airway. The lower pedestal 1 and the upper pedestal 2 form a vertical airway 3 inside, which is used to achieve the upper and lower transition connection of exhaust, and has the exhaust and ventilation functions of traditional exhaust ducts.

[0031] The lower cap 1 is provided with reserved steel bars 4 extending outward from the side, and the reserved steel bars 4 extend outward from the four sides of the rectangle of the lower cap, and are used to bind and connect with the steel bars of other composite plates, walls, columns or beams, and finally form a floor structure. The lower cap 1 is provided with truss steel bars 5 extending outward from the upper end surface, and preferably the truss steel bars 5 are only located on the left and right sides of the lower cap 1, so as to improve the wrapping effect of the secondary slab pouring concrete.

[0032] The lower support 1 is provided with a socket 6 located at the lower end of the vent 3, and the cross-sectional profile of the socket 6 is larger than the cross-sectional profile of the vent 3. The socket 6 is used for inserting and positioning the lower exhaust duct and ensuring that the internal channel of the lower exhaust duct is opposite to and connected with the vent 3.

[0033] Since the vent 3 is arranged inside the upper seat 2, the cross-sectional profile of the upper seat 2 is naturally larger than the cross-sectional profile of the vent 3. The upper seat 2 is used to directly insert into the upper exhaust duct for positioning and ensure that the internal channel of the upper exhaust duct is opposite to and connected with the vent 3.

[0034] Example 2

[0035] refer to Figure 4 As shown, a building structure with exhaust ducts connected to each floor includes an upper exhaust duct 7 and a lower exhaust duct 8, and also includes the prefabricated components of Example 1.

[0036] The upper exhaust duct 7 is connected to the upper support 2. Specifically, the upper support 2 is inserted into the internal airway of the upper exhaust duct 7, and ensures that the internal airway of the upper exhaust duct 7 is opposite to and connected with the vent 3. The upper support 2 cannot be completely inserted into the upper exhaust duct 7, and the height must be provided for the secondary pouring of the lower support 1. At the same time, the lower end surface of the upper exhaust duct 7 is the pouring height of the floor slab. Sealing mortar is filled between the upper exhaust duct 7 and the upper support 2 to ensure the sealing effect of the connection gap.

[0037] The lower exhaust duct 8 is connected to the lower platform 1. Specifically, the lower exhaust duct 8 is inserted into the socket 6 of the lower platform 1, and the internal airway of the lower exhaust duct 8 is relative to and connected with the vent 3. The lower exhaust duct 8 is completely inserted into the socket 6, and the sealing mortar is filled between the two to ensure the sealing effect of the connection gap.

[0038] The use of the utility model:

[0039] The first step is to position and install the prefabricated components according to the reserved openings on the floor.

[0040] The second step is to cast the prefabricated components and floor slabs together.

[0041] The third step is to insert the upper exhaust duct into the upper support seat of the prefabricated component.

[0042] Step 4: insert the lower exhaust duct into the socket at the bottom of the prefabricated component.

[0043] Step 5: Pour concrete on the prefabricated component until it is flush with the floor slab.

[0044] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
