Background
With the transformation, upgrading and development of the building industry, more and more fabricated buildings are provided, and accordingly, the traditional construction process cannot meet the construction requirements of the fabricated buildings. How to effectively plug the through-floor hole of the pipeline is a great technical difficulty in the construction of the fabricated building.
The existing construction method is to use a finished product mold to carry out mold hanging. Earlier with the basic unit watering moist before the entrance to a cave shutoff, if former reservation hole is too smooth still needs the chisel hair, then adopt C20 stone to construct, an entrance to a cave divides 2 times to pour, pours half for the first time, vibrates closely knit. And pouring a second layer after the strength of the first layer of concrete reaches, smearing solid press polish on the surface, plugging with waterproof requirements, pouring the second layer, reserving the depth of 5-10 mm, and plugging the reserved part by using a leakage plugging agent additional layer to ensure that the pipe root has no leakage.
However, the construction period of the prior art is long, the additional layer is added in the two times of pouring for at least 3 days for construction, the concrete still needs to be automatically mixed if no fine aggregate concrete exists on site, and the concrete and the additional layer of the leakage stoppage king are easy to dehydrate and crack if not maintained in time in high-temperature weather in summer. These can create water leakage concerns.
To this end, we propose a new pipe hanging mold process for prefabricated buildings to solve the above problems.
