摘要： PURPOSE: To improve yield strength of a structure by inserting a square spiral reinforcement bar in a piercing longitudinal hole formed by a hollow part of each form block in an opening periphery, and filling the hole with concrete or mortar. CONSTITUTION: In an opening periphery of a structure formed by a form block A, a square spiral reinforcement bar 2 is inserted in a longitudinal hole piercing vertically, which is formed by a hollow part 1 of each form block A stacked vertically, and the hole is filled with concrete or mortar. Thus, the concret or mortar filled in the longitudinal hole is constrained by the square spiral reinforcement bar 2, so that cracks or collapse of the concrete or mortar can be prevented to improve yield strength of the structure formed by the form block A.

摘要： PURPOSE:To get an isolator which is easy to be manufactured and adjusted in its rigidity, by setting a reinforcement between a pair of upper/lower steel plates, and filling up there with a resin mixed cement filler. CONSTITUTION:In case of fixing an upper steel plate 1 and a lower steel plate 2 to an upper structure and a foundation respectively, with bolts inserted into bolt-holes 6 of said upper/lower steel plates 1,2, vibration from the upper structure or vibration from the fundamental structure, which is generated at such as an earthquake, is absorbed or intercepted by a cement filler 4 which is set between the upper/lower steel plates 1,2, and vibro-isolation effect and seismo- immunity effect are given in this way. As this cement filler 4 is reinforced by steel fibers 3 and reinforcing strings, the final durability and safety of the isolator are raised. Properties of this isolator can be regulated in various ways, by varying the aggregate ratio, the water cement ratio, the polymer mixing ratio, and steel fiber mixing ratio of the cement filler 4, and consequently, the rigidity of the isolator can be regulated in the range of 100 times in terms of elastic modulus.
