PROBLEM TO BE SOLVED: To provide a further improved function of countermeasure for mainly a laying block against hot weather in summer.SOLUTION: The present invention relates to a dual structure block 3. The laying block 3 is molded in two layers, i.e., a base layer 1 composed of an aggregate compressed by a bonding agent, and a surface layer 2 composed of an aggregate and a hollow grain 11 dispersed therein and compressed by a bonding agent. At this time, the hollow grain 11 may be made from perlite as a raw material and has the grain diameter of 50 to 500μ. Furthermore, the heat transfer coefficient of the base layer 1 is made higher than the heat transfer coefficient of the surface layer 2. At this time, the base layer 1 may efficiently dissipate heat applied to the surface layer 2 to the ground through the base layer 1 by dispersing and mixing a mixture material 21 having higher heat transfer coefficient than that of the aggregate, or by raising the filling rate of the material to improve the density. Then, the mixture material 21 may be carbon such as graphite, and preferably earthy graphite.SELECTED DRAWING: Figure 1
【課題】主に、敷設ブロックの夏場の暑さ対策機能をより一層高められるようにする。【解決手段】二層構造の敷設ブロック３に関する。敷設ブロック３を、骨材を接合材で固めた基層１と、骨材に中空粒体１１が分散されて接合材で固められた表層２とで二層に成型する。この際、中空粒体１１は、パーライトを原料として、５０〜５００μの粒径をなすものとしても良い。また、基層１の熱伝導率を表層２の熱伝導率より高くしたものとする。この際、基層１は、骨材より熱伝導率の良い混和材２１を分散混合するか、または、材料の充填率を高めて密度を高くすることで、表層２に加わった熱を、基層１を通じて効率良く地中へ逃がせるようにしても良い。そして、混和材２１は、黒鉛などのカーボン、のぞましくは土状黒鉛としても良い。【選択図】図１
