Description

Technical Field

[0001] This utility model relates to the field of embedded sleeve technology, and in particular to an embedded sleeve that is easy to disassemble. Background Technology

[0002] Pre-embedded sleeves are generally used in structures where pipes pass through walls and require general waterproofing, or as single-story leak-proof connectors in construction, chemical, steel, water supply, and sewage treatment industries, as well as for pre-embedding drainage pipes through cast-in-place floor slabs.

[0003] Most pre-embedded sleeves on the market are one-piece designs. The nail holes of these sleeves are located on the outside of the bottom. Although this makes them easy to fix to the formwork, the cement will submerge the nail and screw heads when pouring cement. This means that when the formwork needs to be removed, the nails and screws can only be forcibly removed, which can easily damage the pre-embedded sleeve. After the formwork is removed, the lower part of the nails and screws will be exposed on the next layer of ceiling, which requires cutting and grinding. Even after cutting and grinding, the cut areas of the nails and screws will rust after a period of time, requiring rust prevention treatment. The process is complicated. Therefore, a pre-embedded sleeve that is easy to disassemble is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a pre-embedded sleeve that is easy to disassemble, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0030] An easily disassembled pre-embedded sleeve works on the following principle:

[0031] 1): When it is necessary to install the pre-embedded sleeve, the base 3 can be placed on the base plate 1, and the first screw 5 can be threaded through the bracket 4 and connected to the base 3 on the base plate 1, so that the base 3 can be locked on the base plate 1.

[0032] 2): Place the sleeve 2 onto the base 3, then use the second screw 7 to pass through the cover plate 8 and insert it into the threaded sleeve 6. Then rotate the second screw 7 to move it into the threaded sleeve 6, thus completing the installation of the sleeve 2.

[0033] 3): After the concrete pouring is completed, the second screw 7 is disassembled, and the cover plate 8 can be quickly removed. At this time, the nut of the first screw 5 will be exposed, which makes it easy to disassemble the first screw 5 and release the lock on the base 3. Finally, the base 3 can be pulled out from the sleeve 2, which makes it easy to quickly disassemble the base 3 and the cover plate 8.

[0034] In summary, this easily disassembled embedded sleeve allows for easy installation. The base 3 is placed on the base plate 1, and the first screw 5 is threaded through the bracket 4 and connected to the base 3 on the base plate 1, locking the base 3 in place. The sleeve 2 is then placed on the base 3, and the second screw 7 is inserted through the cover plate 8 into the threaded sleeve 6. Rotating the second screw 7 allows it to move into the threaded sleeve 6, completing the installation of the sleeve 2. At this point, the sealing ring 17 is inserted into the sealing groove 18, preventing concrete from entering the sleeve 2 through the gap between the sleeve 2 and the cover plate 8. After the concrete is poured, the second screw 7 is removed, allowing the cover plate 8 to be quickly removed, exposing the nut of the first screw 5, facilitating its disassembly and releasing the lock on the base 3. Finally, the base 3 can be pulled out of the sleeve 2. This allows for quick disassembly of the base 3 and cover plate 8. Furthermore, the first screw 5's location at the top of the sleeve 2 makes it easier to disassemble using tools.
