Hanging mold construction is in the pouring of concrete, because the lower part does not have the support conditions (that is, there is no way to support the following), or the layer height is too high, and the amount of pouring is small, the cost of support is too high, the use of hanging mold.
Concrete practice: as the name suggests, the template is suspended from above, such as pouring a floor hole, the template by the frame in the floor on the channel steel (square steel, etc.) with wire (reinforcing steel) hanging, after pouring concrete and then dismantle the template, it is lifting mold construction.
A performance of hanging mold in the project:
1, in the construction of different elevations of the structure, the two elevations of the structure to be constructed at the same time, we will use the side of the mold to the higher part of the block, the side of the mold in the low elevation structure of the pad, the pad is placed in the low elevation of the structure of the reinforcing bars above. Generally 4,5cm cement mortar pads, such a template, we also call "hanging mold".
2, in the construction of the floor, when the lower floor space is not enough, for example, has been installed in advance in the lower floor above the larger equipment, there is not enough space to support my upper floor bottom mold, then this time also need to use the hanging mold, this time the lifting mold should be calculated.
There is another kind of hanging mold is used to seal the bathroom and other reserved pipes installed after the reserved hole, this is to bear the vertical load, the general use of the template lower support, the upper hanging form.
Expanded:
The lifting formwork is what makes the elevator pit for the foundation. It's where some formwork is put together to form something like a tall cabinet, and it's placed in a pit that's formed when it's surrounded by rebar ties.
Then the concrete is struck, and something is used to hold the cabinet-like lifting mold down, because the concrete is buoyant to lift it upward. Otherwise the pit won't be deep enough.
When the concrete is solidified, from the top of the cabinet, go in, because the upper part is not closed rectangular well. Just inside, remove the formwork. In this way, the concrete elevator pit is formed.
