Recently, the historical value of brick buildings built during the Meiji and Taisho Eras has been recognized, and the number of buildings designated as cultural properties has increased. In order to keep the brick buildings in a good state of preservation, basic data on brick and the jointing which compose the brick buildings as well as the physical properties of the masonry structure consisting of the brick and the jointing must be collected. In this study, physical properties of bricks used in various brick buildings were investigated. Based on the results of the investigation, methods of repair for the brick buildings' long-term preservation were evaluated.In order to obtain basic data on the physical properties of bricks, which are used for evaluating the possibility of the brick buildings' long-term preservation, bricks collected in various places in Japan were investigated. Consequently, it was found that various physical properties of the bricks changed according to the passage … More of time. Namely, the compressive strength and the Young's modulus decreased, the freeze-thaw resistance increased, the porosity decreased and the strain increased due to repeated dryness and moisture. Moreover, when the Young's modulus estimated from the ultrasonic pulse velocity was compared with various physical properties obtained in previous studies, although a clear relationship among the various physical properties of the bricks was hardly detected, it became clear that reinforcement of the bricks' compressive strength and lowering of the bricks' capillary tube and movement were effective for long-term preservation.We have investigated the repair method of injecting repair materials into the unfilled joint parts of brick walls, a method which is generally adopted in brick buildings' preservation. In order to investigate the improvement in dynamic properties by this method, several bricks' materials and the mixing ratios of repairing materials for joint parts were provided. In addition, an unconfined compression test and a box shear test were performed using a brick masonry structure consisting of the brick and the jointing, in which various repairing materials were injected into the gaps in joint parts. Consequently, the difference in the fracture process between materials composing the masonry structure, and the great improvement of strength in the injected repairing materials, were confirmed.

近年来，明治和大正时期建造的砖砌建筑的历史价值得到了认可，被指定为文化财产的建筑数量也有所增加。必须收集构成砖砌建筑物的接缝以及由砖和接缝组成的砌体结构的物理特性。在本研究中，根据结果对各种砖砌建筑物中使用的砖的物理特性进行了调查。调查、修复方法为了获得砖的物理性质的基础数据，用于评估砖砌建筑长期保存的可能性，对日本各地收集的砖进行了调查检验发现，随着时间的推移，砖的各种物理性能发生变化，即抗压强度和杨氏模量下降，抗冻融性增加，孔隙率下降，应变增加。干燥和潮湿。此外，当将根据超声波脉冲速度估算的杨氏模量与先前研究中获得的各种物理性能进行比较时，虽然很难检测到砖的各种物理性能之间的明确关系，但很明显，砖的抗压强度得到增强砖毛细管的降低和移动对于长期保存是有效的。我们研究了在砖墙未填充的接缝部分注入修复材料的修复方法，这是砖砌建筑保存中普遍采用的方法。命令到为了研究该方法对动态性能的改善，提供了几种砖的材料和接缝部分修补材料的混合比例，此外，使用由该砖组成的砖砌体结构进行了无侧限压缩试验和箱式剪切试验。并检查了在接缝部分的间隙中注入各种修补材料的接缝，确认了构成砌体结构的材料之间的断裂过程的差异以及注入的修补材料的强度的显着提高。较少的
