Vibratory technique with liquid frequency generator

摘要

A novelty which supersedes conventional vibration in concrete. By means of this system, an entire surface can be vibrated at once (in-situ concrete); floors and entire ceiling surfaces of: single family dwellings, administrative and residential buildings, school and hospital buildings, production halls, livestock-rearing buildings, and road and de-icing-part construction. Furthermore, it is used for the purposes of ventilation and venting, watering and drainage, heating and cooling (heat exchange and cold exchange in all mentioned areas), etc. Simplification in erection of all concrete ceilings, walls, floor slabs consisting of concrete, lightweight concrete and other materials which harden in a bed. The piston engine with the liquid frequency generator is an advancement for concrete construction. Cuts in material and labour costs, high degree of compaction of materials which harden in a bed (concrete, etc.). Uniform vibratory process of entire surfaces.
