After the rainwater on the roof is collected through the rainwater pipe, it is discharged to the underground drainage pipe. The rainwater pipe is connected from the roof to the underground, and the drainage must be smooth. The existing rainwater pipes are generally exposed or hidden by setting up pipe wells, decorative wrapping and other measures. However, it is difficult to arrange rainwater pipes for buildings with high requirements for interior decoration such as exhibition halls.
[0003] Therefore, in response to the above technical problems, how to provide a drainage device built into a rainwater pipe is a technical problem that technical personnel in this field need to solve. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0027] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] like Figure 1 As shown, in this embodiment, a built-in drainage device is provided, which includes a steel pipe 2, a rainwater pipe 3, a water outlet pipe 5 and a connecting elbow 4. The steel pipe 2 is the main component for forming a steel tube concrete column. When building a pavilion-type building, it can be inserted into a reinforced concrete column foot 1, so that the steel tube concrete column of the pavilion-type building is formed by pouring concrete in the steel pipe 2. The reinforced concrete column foot 1 can be matched with the steel pipe by using other templates, so as to form a reinforced concrete column foot 1 at the bottom of the steel tube concrete column and keep the two stably connected.
[0029] Before the steel tube concrete column is formed, the rainwater pipe 3 is first placed inside the steel tube 2. It can be set at the axis of the steel tube 2, or set away from the axis, ensuring a certain verticality to facilitate the discharge of rainwater.
[0030] The top of the rainwater pipe 3 is fixedly arranged on the roof, and can receive the rainwater after the collection. After the rainwater pipe 3 is arranged, concrete can be poured in the steel pipe 2 to form a built-in rainwater pipe 3.
[0031] Please refer to Figure 1 One end of the water outlet pipe 5 extends into the reinforced concrete column foot 1 and can penetrate the wall of the steel pipe 2, thereby extending into the interior of the steel pipe 2. The other end extends out of the reinforced concrete column foot 1.
[0032] It should be noted that the reinforced concrete column base 1 can also be cast using an external formwork, and the water outlet pipe 5 can be formed into a built-in water outlet pipe 5 during the casting process, thereby forming a concealed drainage structure.
[0033] On this basis, the connecting elbow 4 is used to connect the bottom end of the rainwater pipe 3 and the end of the outlet pipe 5 extending into the steel pipe 2. The connecting elbow 4 is an arc-shaped pipe, which can guide rainwater and buffer the impact of rainwater falling in the rainwater pipe 3 and reduce noise.
[0034] Based on the above embodiments, the present application places the rainwater pipe 3 and the outlet pipe 5 in the steel tube concrete column and the reinforced concrete column base 1 respectively before the reinforced concrete column base 1 and the steel tube concrete column are formed. When pouring concrete, the built-in outlet pipe 5 and the rainwater pipe 3 can be formed, thereby meeting the layout requirements of exhibition hall-type buildings with high requirements for interior decoration.
[0035] Please refer to Figure 2 A stiffening rib plate 6 is also provided inside the steel pipe 2 within the height range of the connecting elbow 4. The stiffening rib plate 6 is used to support the connecting elbow 4 and improve its setting strength, thereby increasing the setting strength of the rainwater pipe 3, the connecting elbow 4, and the outlet pipe 5 as a whole and ensuring its drainage stability.
[0036] In addition, since concrete needs to be poured into the steel pipe 2 , the stiffening rib plate 6 is set as an annular plate, the outer periphery of the stiffening rib plate 6 is fixedly connected to the inner wall of the steel pipe 2 , and the inner periphery of the stiffening rib plate 6 is spaced apart from the connecting elbow 4 .
[0037] At the same time, in order to improve the connection strength between the connecting elbow 4 and the rainwater pipe 3 and the outlet pipe 5, welding can be used here, that is, the two ends of the connecting elbow 4 are respectively welded to the rainwater pipe 3 and the outlet pipe 5. Of course, other connection methods can also be used to ensure high connection strength and seal the connection to prevent accidental leakage of rainwater and improve service life.
[0038] Please refer to Figure 3A plurality of air holes 7 are provided on the stiffening rib plate 6. Since concrete needs to be poured in the steel pipe 2, the space between the stiffening rib plate 6 and the connecting elbow 4 can pass through concrete, so that the concrete enters the space under the stiffening rib plate 6 to form a stable reinforced concrete column base 1 structure and a steel tube concrete column structure.
[0039] The air holes 7 are used to discharge the air under the stiffening ribs 6, so that the concrete can smoothly enter the lower side of the stiffening ribs 6, and at the same time increase the pouring density of the lower concrete to ensure the strength of the reinforced concrete column foot 1 and the steel tube concrete column.
[0040] Of course, the space between the steel pipe 2 and the rainwater pipe 3 is also used to fill concrete, and during the pouring process, a concrete structure for supporting the connecting elbow 4 will inevitably be formed in the interval between the stiffening rib plate 6 and the connecting elbow 4, thereby forming a fixed support for the connecting elbow 4.
[0041] The outlet pipe 5 is arranged obliquely downward or horizontally and buried in the concrete of the reinforced concrete column foot 1. The outlet pipe 5 can be further reinforced by the concrete of the reinforced concrete column foot 1. Similarly, the concrete in the steel pipe 2 can further reinforce the rainwater pipe 3, thereby forming a stable built-in drainage structure.
[0042] It should be noted that the steel pipe 2, rainwater pipe 3, outlet pipe 5 and connecting elbow 4 can all be made of existing materials, so the material selection is convenient and quick, and easy to implement. At the same time, the device has high safety, and only the outlet pipe 5 is partially exposed, which can meet the layout requirements of high-demand buildings such as exhibition halls. At the same time, the above-mentioned steel tube concrete column is also suitable for steel concrete with built-in steel pipes.
[0043] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0044] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
