ある。<Prior art> The horizontal joint between the upper and lower members, at least one of which is made of a precast member, must be able to smoothly transmit the vertical force of the upper member downward, and must also be able to smoothly transmit the vertical force of the upper member downward. It is also necessary to resist additional axial force.

強度低下を招くという問題点があった。<Problem to be solved by the invention> However, in the conventional example described above, it is difficult to place the hard-mixed mortar evenly on the lower member, and when using sandals or level liners, the work is even more complicated. This results in extremely poor construction workability, and if the mortar is not spread evenly, it may crack partially after hardening, resulting in structural defects. Also,
Because mortar has no reinforcing bars, repeated earthquake forces can cause localized fractures and cross-sectional defects, leading to a reduction in the overall strength of the structure.

However, as time passes, it hardens more than mortar and becomes integrated with concrete, and even after it hardens, it does not become brittle even when subjected to vibrations, so problems such as cracking due to earthquake force occur. do not have. As a result, installation on the upper or lower member can be carried out in block units, and the installation efficiency is significantly improved compared to the case of conventional mortar.

It is evenly distributed and further bites into these joint surfaces and binds them together. However, over time, the bonding material 4
As the material hardens and reaches practical strength, it forms a bonding layer with higher strength and toughness than mortar. Therefore, even if the bonding material 4 is subjected to an earthquake force after hardening, it will not crack or break. In addition, the bonding material 4 is
The efficiency of construction work is significantly improved because blocks that have been formed into blocks of a predetermined shape, size, and thickness through factory production and shipped in such a block state can be used as they are.

This is done by attaching a bonding material 4 made of super fiber impregnated with a thermosetting resin to the joint surface of the upper member 1, and then placing the joint surface of the upper member 1 on the joint surface of the lower member. The upper member 1 and the lower member 2 are bonded and bonded and hardened by the bonding material 4. Also in this example,
Similar to the above embodiments, it is possible to form a bonding layer that is hard and has high resistance, and also to prevent cracking, thereby making it possible to construct a highly durable structure.
