摘要： PURPOSE:To thicken a covering material and increase the fireproof ing function of a structure, by coating the whole external surface of the structure or a part thereof with a covering material having a larger thermal conductivity than a specified value. CONSTITUTION:A structure 1 is coated with a covering material 2 having 0.45 or larger in the thermal conductivity at the whole external surface or a part thereof. A metallic substance such as gold, silver, copper, aluminum, etc., having a sufficiently larger thermal conductivity than iron is used as the covering material 2. Moreover, a heat-insulating fireproofing cover material 4 coating the external surface of the structure 1 is put between the external surface and the covering material 2 to diffuse the heat with the covering material 2 when the heat acts on the covering material 2 on the external surface of the structure 1 due to a fire or the like. That is, it prevents the covering material 2 from thermal partial concentration and prevents the structure from the thermal action by diffusing the heat. The fireproofing cover material 4 prevents more effectively the structure from the heat acting thereon.

摘要： PURPOSE:To provide a PCa slab, onto which plastering material can plaster without surface smoothing treatment with wiping die at the following process, which is necessary when the smooth ground finish is requested for finishing coating or the like. CONSTITUTION:In a steel form 1, which has a smooth bottom surface, reinforcing bars 2 are arranged. At the same time, cement-based mortar 3, which has high fluidity and the amount of which is enough as much as for covering the whole bottom surface of the form 1, is poured in the form 1. At the time, when the fluidity of the cement-based mortar 3 is lost, concrete 4 is placed in the form so as to manufacture a PCa slab 5 by curing and hardening the concrete.
