Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a dry damper for a civil building structure includes an upper plate 1, a main spring 5 fixedly connected to a bottom surface of the upper plate 1, a lower plate 2 fixedly connected to a bottom end of the main spring 5, a horizontal pipe 7 fixedly connected to a bottom surface of the upper plate 1, an auxiliary spring 10 fixedly connected to an inner wall of the horizontal pipe 7, a weight 9 fixedly connected to an inner end of the auxiliary spring 10, a lifting rope 8 fixedly connected to a top end of the weight 9, and a top end of the lifting rope 8 fixedly connected to the bottom surface of the upper plate 1.

Wherein, the quantity of assisting spring 10 is four, and four are assisted every two of spring 10 and are divided into about for a set of altogether and control two sets ofly, and every two are assisted spring 10 symmetric distribution on the side about pouring weight 9 for pouring weight 9 receives horizontal vibrations when the bottom of lifting rope 8 is connected and takes place the swing, and drives the reciprocal vibration of the assisting spring 10 of pouring weight 9 both sides, and the heat production is vibrated to assisting spring 10, and mechanical energy converts heat energy into, reduces the vibrations energy, weakens the vibrations effect.
