[0002] According to the requirements of the specifications, within the 500mm×500mm area of ​​the gutter rainwater outlet, the surface layer should be set with a drainage slope of 5%, made into a cup-shaped mouth, sloping towards the rainwater pipe. In traditional technology, the slope construction of the rainwater outlet cup-shaped mouth generally adopts the following methods: one is to use wooden formwork to support the formwork for pouring concrete at the rainwater outlet when pouring the gutter concrete. The wooden formwork has poor stability and can only be used once. After removing the formwork, the surface layer needs to be plastered and the four corners of the cup-shaped mouth need to be caulked. This method has low construction efficiency, low turnover rate of wooden formwork, and large waste of materials; the second is to use cement mortar to level and smooth the rainwater outlet into a slope several times after the construction of other parts of the gutter is completed. The plastering thickness is too large, the strength of cement mortar is low, and the slope is difficult to control, which can easily cause cracking or poor appearance quality. Therefore, it is necessary to provide a standardized mold for the construction of the gutter rainwater outlet cup-shaped mouth that can effectively solve the above problems. Utility Model Content

[0003] In view of the above defects or improvement needs of the prior art, the utility model provides a standardized mold for a rainwater outlet. After the center positioning pipe is nested on the pre-buried rainwater pipe, the inner mold and the outer mold form a slope to facilitate the one-time molding of the concrete at the cup mouth position. At the same time, a protrusion is provided on the lower side of the steel plate strip to embed into the concrete, and the steel plate strip is used as a caulking strip for the concrete joints at the four corners of the rainwater outlet, which reduces the operation steps of secondary cement mortar slope adjustment and caulking at the four corners after concrete pouring.

[0004] In order to achieve the above-mentioned purpose, according to the utility model, a rainwater outlet shaping mold is provided, including an outer mold, an inner mold, a steel plate strip, a positioning tube and a connecting steel plate, wherein the outer mold is a regular polygon structure formed by connecting and fixing a plurality of side standing steel plates end to end, and the inner mold is a regular polygon structure formed by connecting and fixing the same number of angle steels end to end, the height of the steel plate is greater than the height of the angle steel, and the inner mold is placed at the center of the outer mold, and the side walls of the two are arranged in parallel;

[0005] The steel strips are welded and fixed at the corresponding corners of the outer mold and the inner mold respectively. The lower side of the steel strips protrudes and is embedded in the concrete. The steel strips serve as caulking strips for the concrete joints after the rainwater inlet is poured. The positioning tube is a vertically arranged tubular structure, and the positioning tube is fixed to the center of the inner mold by connecting the steel plate.

[0006] Furthermore, the L-shaped extension of the angle steel is located at the bottom of the mold, and the L-shaped extension is arranged toward the center of the mold.

[0007] Furthermore, the number of the steel strips is consistent with the number of the angle steels, and one end of the steel strip is fixed to the middle of the angle steel, and the other end is fixed to the side wall of the positioning tube.

[0008] Furthermore, the positioning tube is nested on the rainwater pipe, and the diameter of the positioning tube is larger than the diameter of the rainwater pipe.

[0009] Furthermore, the height of the inner mold is set at a slope of 5% inwardly according to the height of the outer mold.

[0010] Furthermore, it comprises a handle, and the handle is arranged on the side wall of the steel plate opposite to the outer mold.
