Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a sleeve positioning structure for an aluminum template. Background Art

[0002] During the concrete pouring process of a house, a large number of sleeves for placing water supply and drainage pipes need to be embedded in the cast-in-place concrete of the building floor. In order to ensure the accurate installation of the water supply and drainage pipes, the sleeve embedded in the cast-in-place concrete must fully meet the design requirements and cannot be tilted or shifted. At present, in order to ensure that the sleeve does not tilt or shift during concrete pouring, two methods are mainly used on site: one is to set a positioning plate on the aluminum formwork of the cast-in-place concrete of the floor, plug the bottom of the sleeve into the positioning plate, and then cast-in-place concrete operations to achieve the embedding of the sleeve. The second is to use thin iron wire to tie the sleeve to the structural steel bars, and then cast-in-place concrete operations to achieve the embedding of the sleeve.

[0003] However, when the lower end of the casing is plugged into the positioning plate, the bottom of the casing can withstand external pressure through the positioning plate, but the top of the casing is out of control. When pouring concrete, the casing is easily tilted or even detached from the positioning plate under the action of external force. When using thin iron wire to bind the casing, it is easy to deform and loosen due to external force, causing the casing to deviate.

[0004] In summary, both methods will cause the casing to tilt and loosen, making the casing between the upper and lower floors not in the same straight line, resulting in the need for secondary chiseling, hanging molds and grouting when installing the water supply and drainage pipes. This not only increases working hours, consumes materials, increases construction costs, but also generates a large amount of garbage, and does not meet the requirements of green construction. In addition, in bathrooms and kitchens with waterproofing requirements, secondary chiseling will also cause water leakage risks. Utility Model Content
