Technical Field

[0001] The utility model relates to the technical field of water stop joint construction, in particular to an easily disassembled and rotatable aluminum formwork floor water stop joint pre-embedded fixing device. Background Art

[0002] At present, my country's construction technology has developed to a relatively high level, and people's understanding of housing construction and their requirements for the quality of construction projects are getting higher and higher. Various leakage phenomena in bathrooms, kitchens, balconies and other parts have gradually become one of the common quality problems in current housing construction projects. At present, high-rise buildings mostly use aluminum alloy formwork construction technology and use pre-buried water stop joints to prevent leakage around pipes.

[0003] The fixing method of the water stop joint on the aluminum alloy formwork is still the same as that of the ordinary wooden formwork, that is, it is fixed with screws on the outside of the water stop joint through the four screw holes provided by the water stop joint. This method is feasible in wooden formwork, but the aluminum alloy formwork is different from the ordinary wooden formwork. It is a rapid demolding system. The top plate formwork is removed the next day after the floor decking concrete is poured. At this time, the concrete strength of the floor decking is still very low, and the bonding strength between the embedded water stop joint and the concrete is small. When the top plate formwork is removed, the connection between the embedded water stop joint and the formwork can easily cause the water stop joint to be pulled, and in severe cases, damage may occur, thereby causing cracks between the embedded water stop joint and the surrounding concrete, resulting in the risk of leakage around the embedded water stop joint. Therefore, an easily removable and recyclable aluminum formwork floor water stop joint embedded fixing device is needed to solve the above problems. Utility Model Content

[0007] Preferably, any of the above schemes is that a first positioning ring is fixedly connected to the top side of the aluminum template, and a second positioning ring is fixedly connected to the bottom side of the circular cover plate.

[0008] Preferably, any of the above solutions has a rotating handle fixedly connected to the outer surface of the top end of the sleeve.

[0009] Preferably, any of the above schemes is that the positions of the hollow threaded rod and the connecting nut correspond to each other, and the sizes of the hollow threaded rod and the nut are matched.

[0010] Preferably, according to any of the above schemes, a portion of the screw rod is located inside the hollow threaded rod, and the maximum diameter of the screw rod is smaller than the inner diameter of the hollow threaded rod.
