[0029] The curved pilasters 3 form a surrounding shield on the outside of the outdoor rainwater pipe 6, thereby preventing the outdoor rainwater pipe 6 from being exposed and affecting the aesthetics of the building. During the construction of the building's exterior wall decorative panels 5, the embedded parts 1 are installed on the facade of the building structure to facilitate the installation of the columns 2.

[0030] A pair of columns 2 serve as detachable mounting points for the arc-shaped pilasters 3 on the facade of the building structure, allowing the arc-shaped pilasters 3 to be installed on the facade of the building structure in a detachable manner, ensuring a firm installation while making disassembly and assembly more convenient, thereby facilitating the disassembly, repair and replacement of the outdoor rainwater pipe 6.

[0031] Please see the attached Figure 1 and attached Figure 2 The length of the embedded part 1 is consistent with the thickness of the building's exterior wall decorative panel 5, so that one end of the embedded part 1 is fixedly connected to the building's steel column 7, and the other end of the embedded part 1 is flush with the facade of the building's exterior wall decorative panel 5 and fixedly connected to the column 2.

[0032] The embedded part 1 is hidden in the building's exterior wall decorative panel 5 to avoid being exposed and affecting the building's aesthetics, and the outer end surface of the embedded part 1 is flush with the outer facade of the building's exterior wall decorative panel 5, which facilitates the installation of the column 2.

[0034] According to the length of the outdoor rainwater pipe 6, the arc-shaped wall column 3 can adopt a segmented structure, which is convenient for production and installation, has good adaptability to outdoor rainwater pipes 6 of different lengths, and is also convenient for subsequent local maintenance and replacement of some sections of the outdoor rainwater pipe 6.

[0035] The width of the widened section arcuate wall column 302 is greater than the width of the main section arcuate wall column 301, and the width of the widened and thickened section arcuate wall column 303 is greater than the width of the main section arcuate wall column 301. Depending on the length of the bent section, the widened section arcuate wall column 302 can also adopt a segmented structure, and depending on the length of the bottom drain outlet, the widened and thickened section arcuate wall column 303 can also adopt a segmented structure.

[0036] Preferably, the main section arc-shaped wall column 301, the widened section arc-shaped wall column 302 and the widened and thickened section arc-shaped wall column 303 can adopt a semi-circular arc surface structure. After installation, a semi-cylindrical cavity is formed between the arc-shaped wall column 3 and the building exterior wall decorative panel 5, and the outdoor rainwater pipe 6 is located in the cavity.

[0037] The splicing length of the main section arcuate pilasters 301 can be adaptively adjusted according to the length of the main portion, i.e., the vertical section, of the outdoor rainwater pipe 6, ensuring effective shielding of the main portion. Typically, the outdoor rainwater pipe 6 has a curved section at the top, and the widening of the widened section arcuate pilasters 302 at the top ensures effective shielding of the curved section.

[0041] The mounting portion 306 of the L-shaped structure can be fitted onto the outer side surface of the column 2 and the side away from the exterior wall decorative panel 5 of the building. The size of the mounting portion 306 of the L-shaped structure can be adapted to the size of the column 2 to ensure effective shielding of the column 2, thereby preventing the column 2 from being exposed and affecting the overall aesthetics of the building.

[0042] Please see the attached Figure 3 The outer side of the top of the widened arc-shaped pilaster 302 is connected to the building exterior wall decoration panel 5 at the top of the building through the ceiling outer edge 8.

[0043] The top outer side of the widened section of the arc-shaped pilaster 302 is fixed to the building exterior wall decoration panel 5 at the top of the building through the ceiling outer edge 8, so that the entire arc-shaped pilaster 3 and the building exterior wall decoration panel 5 form a whole, which can not only improve the installation firmness of the arc-shaped pilaster 3, but also ensure the integrity and aesthetics of the exterior decoration.

[0044] Please see the attached Figure 8 and attached Figure 9The rain grate 4 includes a grate body 401, a mounting rod 402, an L-shaped connector 403 and a seal 404; the cross-section of the grate body 401 is an arc-shaped structure, and several mounting rods 402 are arranged circumferentially in the grate body 401, and the upper ends of the several mounting rods 402 are respectively connected to the bottom of the widened and thickened arc-shaped wall column 303; one end of the L-shaped connector 403 is detachably connected to the end of the grate body 401 by a rivet, and the other end of the L-shaped connector 403 is detachably connected to the column 2 by a self-tapping screw; the seal 404 is filled between the end of the grate body 401, the other end of the L-shaped connector 403, and the facade of the building exterior wall decorative panel 5.

[0045] The mounting rods 402 can be made of round steel, with a gap between adjacent mounting rods 402 to serve as rainwater filters. The mounting rods 402 can function as a grate and have a decorative effect. The number and spacing of the mounting rods 402 can be adjusted according to actual usage requirements.

[0046] The L-shaped connector 403 is used to detachably mount the ends of the grate body 401 to a pair of upright posts 2, making assembly and disassembly convenient, facilitating the cleaning of debris from the rain grate 4 and the repair and replacement of the rain grate 4. The seal 404 is used to seal the connection between the L-shaped connector 403 and the upright posts 2, preventing rust and corrosion of the L-shaped connector 403, self-tapping screws, etc. caused by repeated rainwater erosion.

[0047] Example 1: In an outdoor decoration project of a certain building, a 100mm thick flat rock wool sandwich insulation decorative panel, namely the building exterior wall decorative panel 5, is constructed on the outside of the building's steel column 7. An outdoor rainwater pipe 6 is exposed on the outside of the building.

[0048] Please see the attached Figure 1 To the attached Figure 9 , the construction method of the utility model is:

[0049] Before installing the exterior wall decorative panels 5, use 12# channel steel as embedded parts 1. The length of the 12# channel steel is determined based on the thickness of the exterior wall decorative panels 5. One end of the embedded part 1 is welded to the building's steel column 7. The embedded parts 1 are placed in pairs on either side of the outdoor rainwater pipe 6. The number of pairs of embedded parts 1 can be adjusted to suit the installation requirements of the columns 2. After the embedded parts 1 are installed, the exterior wall decorative panels 5 are installed. The exterior wall decorative panels 5 are installed using conventional techniques, which will not be detailed here.

[0050] 2. Square steel tubes are used as columns 2, which can be installed on the facade of the building's exterior wall decorative panel 5. A pair of columns 2 are welded to several pairs of embedded parts 1, and a pair of columns 2 are arranged parallel and symmetrically on both sides of the vertical section of the outdoor rainwater pipe 6.

[0051] 3. A dark grey curved aluminum plate with a thickness of 3 mm is used as the curved pilaster 3. The curved surface size of the curved pilaster 3 can be made according to the size adaptability of the outdoor rainwater pipe 6, and the height of the curved pilaster 3 can be made according to the height adaptability of the building's exterior wall decorative panel 5.

[0052] The vertical section of the outdoor rainwater pipe 6 is constructed using a splicing system of main curved pilasters 301. The bottom of the upper main curved pilaster 301 is connected to the vertical section of an angle plate 305 via a butt joint plate 304. The horizontal section of the angle plate 305 is connected to the lower top panel of the lower main curved pilaster 301 and secured with rivets. A butt joint plate 304 forms a 40mm high butt joint between the upper and lower main curved pilasters 301, aligning with the butt joint of the building's exterior wall decorative panels 5.

[0053] The ends of the main section arc-shaped wall column 301 are respectively attached to the two surfaces of the square steel pipe through the L-shaped mounting portion 306 and fixed by tapping screws, which ensures firm and reliable installation while facilitating disassembly.

[0054] 4. If there is a bend at the top of the outdoor rainwater pipe 6, a widened section arcuate pilaster 302 can be used based on the size of the bend. A relatively wide base plate is provided on the bottom surface of the widened section arcuate pilaster 302, and a butt joint connecting plate 304 is installed. This allows the butt joint connecting plate 304 of the widened section arcuate pilaster 302 to be matched and connected to the top plate of the uppermost main section arcuate pilaster 301 via an angle plate 305. The widened section arcuate pilaster 302 accommodates the horizontal position changes of the bend of the outdoor rainwater pipe 6. The width of the widened section arcuate pilaster 302 can be determined based on the size of the bend of the outdoor rainwater pipe 6, and the height of the widened section arcuate pilaster 302 can be consistent with the height of the building's exterior wall decorative panel 5.

[0055] The outer side of the top of the widened arc-shaped pilaster 302 is connected to the building exterior wall decoration panel 5 at the top of the building through the ceiling outer edge 8 to form a whole.

[0057] The mounting rods 402 are made of 12mm diameter round steel, and are appropriately high enough to cover the lower end of the drain outlet. The grate body 401 is constructed from the same curved aluminum plate as the curved pilasters 3. The inner and outer curved aluminum plates are connected by mounting rods 402 spaced 100mm apart. Rainwater is filtered and discharged through the gaps between the mounting rods 402. The diameter of the grate body 401 matches the diameter of the widened and thickened curved pilasters 303, which is the diameter of the main curved pilasters 301 plus 400mm, meaning it is 200mm wider on both sides.

[0058] The mounting rod 402 is welded to the bottom of the widened and thickened arc-shaped wall column 303 or the butt joint connecting plate 304 at its bottom, and an angle steel is used as the L-shaped connector 403. One end face of the L-shaped connector 403 is connected to the end of the outer arc-shaped aluminum plate and fixed by rivets. The other end face of the L-shaped connector 403 is fixed to the column 2 by self-tapping screws, and is sealed and bonded along the contour of the building's exterior wall decorative panel 5 with weather-resistant sealant to form a seal 404.
