HOLLOW CORE PRECAST SLAB INTEGRATED WITH ONDOL AND ITS CONSTRUCTION METHOD

摘要

A hollow core precast slab integrated with ondol is provided to reduce the period of construction, to simplify a construction process, to improve quality and to cut down on construction expenses by constructing a slab and ondol integrally. The hollow core precast slab integrated with ondol contains a precast slab(10) provided with hollow cores(11) to cut off the loss of heat, hot water pipelines(20) laid in pipeline grooves(12) of the precast slab at regular intervals, and a finishing layer(30) made of topping concrete or finishing concrete and placed on the top of the hot water pipeline. The construction method for a hollow core precast slab integrated with ondol comprises the steps of carrying a hollow core precast slab in a job site using a crane and assembling between a beam and a beam, laying hot water pipelines in upper pipeline grooves of the precast slab at regular intervals, placing a finishing layer on the top of the hot water pipelines and attaching an insulation on the bottom of the precast slab.
