[0029] like Figure 1-8 As shown, a rainwater internal drainage device for a steel structure roof includes a rainwater pipe 2 located in a steel column 1, and the rainwater pipe 2 is fixed to the steel column 1 by a plurality of pipe clamps 3. The top of the rainwater pipe 2 is connected to a connecting pipe 5 obliquely installed inside a steel beam 4, and a 45° elbow is used for connection. The connecting pipe 5 is tilted downward to facilitate the downward flow of rainwater.

[0030] The top of the connecting pipe 5 passes through the steel beam 4 and is connected to a rain gutter device, which is located on the roof. Specifically, the rain gutter device includes a mounting bucket 11 fixedly connected to the top of the connecting pipe 5, a rain gutter 9 is plugged into the interior of the mounting bucket 11, a filter plate 10 is plugged into the top of the rain gutter 9, and an upper cover plate 12 is plugged into the top of the mounting bucket 11. The mounting bucket 11, the rain gutter 9, the filter plate 10 and the upper cover plate 12 are all plug-in connected, without any bolt-connected assembly, so that disassembly and assembly are more convenient, and cleaning, maintenance and replacement are more convenient, quicker, and simpler to operate.

[0031] The bottom of the rainwater pipe 2 is connected to the drainage groove 7 located in the outer wall 6. The drainage groove 7 is located on the outside of the outer wall 6 after passing through the hole at the bottom of the outer wall 6. The bottom of the drainage groove 7 is installed with a water outlet 8. Specifically, the water outlet 8 is located between the drainage grooves 7 and is connected by a 90° connecting elbow to facilitate drainage and prevent water from accumulating at the base of the wall.

[0032] The rain gutter 9 includes a bucket body 901, which is a funnel-shaped structure. A plurality of positioning grooves 902 are provided on the outer period of the bucket body 901. A plurality of stop blocks 903 are distributed on the outer circumference of the bottom of the bucket body 901. The stop blocks 903 are located below the positioning grooves 902, and a plurality of stop blocks 903 are distributed at intervals from the positioning grooves 902. A socket connector 904 is installed at the bottom end of the bucket body 901, and a clamping groove 905 is provided at the top end of the bucket body 901. A plurality of clamping points 906 are installed on the inner wall of the clamping groove 905.

[0033] The filter plate 10 includes a filter body 101, and a clamping ring 103 matching the clamping groove 905 is installed at the bottom of the filter body 101 near the outer edge. The clamping ring 103 is in contact with the clamping point 906, which is used to clamp the clamping ring 103, so that the filter plate 10 is fixed on the top position of the rain gutter 9. The filter body 101 is provided with a plurality of equidistantly distributed filter holes 102, which can filter out some impurities that block the water flow without hindering the flow of rainwater.

[0034] The installation bucket 11 includes a main body 111, and a plurality of positioning protrusions 112 and limiting grooves 113 are installed on the inner wall of the main body 111, which respectively match the positioning grooves 902 and the limiting blocks 903, so as to facilitate the quick insertion and installation of the rainwater bucket 9 on the installation bucket 11. In addition, in this embodiment, a sealing structure is installed between the inner wall of the main body 111 and the outer wall of the rainwater bucket 1 to prevent rainwater from penetrating into the interior of the building along the gap between the two. A socket joint 114 matching the socket joint 904 is installed at the bottom of the main body 111 to play a role in stabilizing the connection. The bottom of the socket joint 114 is integrally formed with a threaded connector 115 threadedly connected to the connecting pipe 5, which is convenient for installation, and a waterproof sealing ring is also provided at the installation position of the two. A water inlet grille 117 is integrally formed on the outer wall of the upper part of the main body 111. A cavity of a water storage area 116 is formed between the water inlet grille 117 and the main body 111. After rainwater reaches the water storage area 116, it is left to stand for a period of time. When the water volume reaches a certain demand, it will flow in from the top of the rain gutter 9 and then flow out along the pipe. This design can prevent some small particles of sand and gravel from directly entering the rain gutter 9. After the last accumulation, the pipe may be blocked, causing the hidden danger of untimely drainage or even failure to drain. A plurality of water inlet holes 118 are opened on the side wall of the water inlet grille 117 for rainwater to flow in, and the water inlet holes 118 can be set as holes inclined downward as needed to facilitate rainwater to quickly enter the water storage area 116.

[0035] The cross section of the water inlet grille 117 is symmetrically distributed in an L-shape.

[0036] The upper cover plate 12 includes a cover plate body 122. A U-shaped groove 121 is installed at the bottom of the cover plate body 122 near the outer edge, which is plugged into the top of the water inlet grille 117 for quick plugging and positioning. The cover plate body 122 has a plurality of through holes 123 distributed around the circumference. The through holes 123 are designed to allow rainwater to fall vertically. Since this part of rainwater does not contact the roof, it will not carry impurities and will directly enter the rain gutter 9 without clogging the pipe.

[0037] The installation process of the utility model is as follows:

[0038] First, when installing the rainwater pipe 2, first locate the rainwater pipe 2 according to the construction drawing, use a ruler to measure the distance between the center of the pipe hole and each side, place the rainwater pipe 2 (using a PVC riser), and use a pipe clamp 3 that matches the diameter of the rainwater pipe 2 to weld and fix the rainwater pipe 2 to the steel column 1;

[0039] Secondly, find the position of the roof water outlet on the frame beam according to the drawing. The upper end of the connecting pipe 5 corresponds to the position of the roof water outlet, and the lower end is connected to the top of the rainwater pipe 2. A 45° elbow is used for pipe connection during connection; the elbow pipe thread at the top of the connecting pipe 5 is connected to the installation bucket 11, the rainwater bucket 9 is inserted into the installation bucket 11, and the filter plate 10 is inserted on the top of the rainwater bucket 9. Finally, the upper cover plate 12 is inserted on the top of the installation bucket 11 to complete the rapid installation of the rainwater bucket device;

[0040] Finally, a stainless steel gutter 7 is installed at the bottom of the rainwater pipe 2. During installation, an angle grinder is needed to cut holes of appropriate specifications for the gutter 7 on the exterior wall 6 made of aluminum plate, and then the gutter 7 is placed on the hole. After the installation is completed, the surrounding gaps are tightly sealed with structural adhesive, and the water outlet 8 is installed at the end of the gutter 7. At this point, the overall roof rainwater device is installed.

[0041] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
