step S1: a bearing with a regular octagonal inner wall cross section is arranged in a hole of the convex tooth on one side of the hinged connection, and a hole with a regular octagonal cross section is arranged on the convex tooth on the other side of the hinged connection.
Convex tooth bearings 81 are arranged on the three round convex teeth 8, and convex tooth regular octagonal holes 91 are arranged on the two round convex teeth 9.
Step S2: and simultaneously penetrating the regular octagonal pin shaft through convex teeth on two sides of the hinge assembly and reserving overhanging sections with equal lengths on two sides of the convex teeth.
The convex tooth bearing 81 and the regular octagonal hole 91 enable the regular octagonal pin shaft 10 to rotate relative to the three smooth convex teeth 8 along with the rotation of the two smooth convex teeth 9; the length of the extended section of the regular octagonal pin shaft 10 is at least not less than the longitudinal length of the damper, so that the regular octagonal pin shaft 10 can be completely inserted into and overlapped on the bearings 7 at two ends in the damper.
Step S3: and respectively placing the two corner dampers into the overhanging sections at the two sides of the pin shaft.
Inserting the regular octagonal torque transmission part 1 into the overhanging regular octagonal pin shaft 10 to ensure that the pin shaft is completely lapped on the bearings 7 at the two ends of the damper; as shown in fig. 2 and 7, the octagonal moment transmission part 1 and the teeth octagonal hole 91 are aligned in the x and y directions at the same time, so that the pin 10 can be smoothly inserted into the damper.
Step S4: the damper is fixed with the same degree of freedom as the teeth on which the bearings are mounted.

Fig. 9 and fig. 10 show a schematic structural diagram of a damping material corner damper installed at a hinge point, and it can be seen that when a vibration load is transmitted to the hinge point, two smooth teeth 9 and three smooth teeth 8 rotate relatively, the two smooth teeth 9 drive a pin shaft 10, the pin shaft 10 drives a regular octagonal torque transmission component 1 to rotate, and further the transmission annular steel plate 2 and the fixed annular steel plate 3 rotate relatively, even if the damping material 4 is sheared and deformed, thereby dissipating energy and controlling the two smooth teeth 9 and the three smooth teeth 8 to rotate relatively.
The damping material corner damper can be installed at a plurality of hinged points of the same building, and because the damper is small in size and only installed at the building nodes, the damper is less restricted by the building space and has less influence on the normal use function of the building structure and the building attractiveness; even in some special building structures or narrow spaces, the conventional support-type damper cannot be installed or has poor effects after installation, and the damper of the present invention can be used as an alternative to the conventional support-type damper.

According to the installation method of the damper, the damper can be uniformly installed after the main body of the building structure is installed, and a plurality of groups of dampers can be installed simultaneously, so that the construction efficiency is high; similarly, if the damper is damaged, the damper can be conveniently repaired or replaced, which is also identical with the mainstream anti-seismic design idea at present.
Of course, the damping material corner damper and the installation method thereof can also be used together with other vibration control methods to further improve the seismic performance of the building structure.
Since construction hinge constructions also come in a variety of configurations, the corner damper of damping material of the present invention can be partially modified for different types of hinge constructions, and if such modifications or variations are within the scope of the claims of the present invention, they are also automatically encompassed by the present invention.
