DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 A mild steel energy dissipator in this embodiment includes two first support plates 1, two second support plates 2 are fixed on the first support plates 1, a first energy dissipation plate 3 fixed on the side opposite to the two second support plates 2 is fixed between the two first support plates 1, the first energy dissipation plate 3 is an open-hole energy dissipation plate, a connecting component is provided on the outer surface of the first support plate 1, two positioning plates 7 are fixed between the two second support plates 2, two partitions 8 are fixed between the two positioning plates 7, and a first energy dissipation plate 3 fixed on the side opposite to the two second support plates 2 is fixed on the side opposite to the two second support plates 2. The second energy dissipation plate 9 is an X-shaped energy dissipation plate. The first energy dissipation plate 3 and the second energy dissipation plate 9 are both made of low yield point steel. Low yield point steel refers to steel with a relatively low yield point and has excellent deep drawing and deep drawing properties, thereby making the seismic performance better and improving the safety performance of the building. The first support plate 1 and the second support plate 2 and the first energy dissipation plate 3 and the second energy dissipation plate 9 are connected by welding. The connection strength of welding is usually higher than that of other connection methods, so that the soft steel energy dissipator can withstand greater pressure. Two shock absorbing mechanisms 10 are arranged between the two partitions 8.

[0022] In this embodiment, the connecting assembly includes two connecting plates 4, a plurality of connecting rods 5 and a plurality of bolts 6. The second support plate 2 and the connecting rods 5 are provided with threaded through holes, and the threaded through holes are adapted to the bolts 6. Through the setting of the threaded through holes, the front and rear connecting plates 4 can be connected. The two connecting plates 4 are respectively connected to the front and rear sides of the first support plate 1. The plurality of connecting rods 5 are fixed to the front side of the rear connecting plate 4, and the plurality of bolts 6 are threadedly connected to the front side of the front connecting plate 4.

[0023] It should be noted that, through the action of the connecting assembly, the two connecting plates 4 can protect the first support plate 1 and the second support plate 2, thereby protecting the internal first energy dissipation plate 3, the second energy dissipation plate 9 and the shock absorbing mechanism 10, and also facilitating the replacement of the first energy dissipation plate 3, the second energy dissipation plate 9 and the shock absorbing mechanism 10.

[0024] See also Figure 3In order to improve the service life of the mild steel energy absorber, the shock absorbing mechanism 10 in this embodiment includes two connecting bins 1001, a shock absorbing assembly, a slide rail 1004 and a mounting plate 1006. The two connecting bins 1001 are respectively fixed to the opposite sides of the two partitions 8, the mounting plate 1006 is connected to the interior of the connecting bins 1001, the shock absorbing assembly is arranged between the two connecting bins 1001, and the slide rail 1004 is fixed to the interior of the connecting bin 1001.

[0025] In this embodiment, the shock absorbing assembly includes four springs 1002, four moving blocks 1003 and two connecting rods 1005. The two connecting chambers 1001 are provided with movable holes on the opposite sides for the connecting rods 1005 to move. Through the action of the movable holes, the connecting rods 1005 can move normally, thereby improving the stability of the shock absorbing assembly during operation. A hinge axis is fixed at the intersection of the two connecting rods 1005. A slide groove is provided on the moving block 1003, and the slide groove is adapted to the slide rail 1004. Through the setting of the slide groove, the moving block 1003 can move stably inside the connecting chamber 1001. The four springs 1002 are respectively fixed on the left and right sides of the two mounting plates 1006, the four moving blocks 1003 are respectively fixed to the springs 1002, and the two connecting rods 1005 are respectively fixed to the four moving blocks 1003.

[0026] It should be noted that when the soft steel energy absorber is deformed, the distance between the two partitions 8 will become larger. At this time, the two connecting compartments 1001 can pull the two connecting rods 1005 to deform, so that the connecting rods 1005 can squeeze the moving block 1003. Through the action of the moving block 1003, the spring 1002 can be squeezed. Through the action of the spring 1002, the deformation of the soft steel energy absorber can be reduced, thereby improving the durability of the soft steel energy absorber.

[0027] The working principle of the above embodiment is:

[0028] (1) When in use, by placing the soft steel energy dissipator inside the building structure, when the earthquake intensity is small, by making full use of the large initial stiffness and deformation sensitivity of the first energy dissipation plate 3, the shock absorption effect can be exerted when the vibration is not large, thereby avoiding the elastic-plastic deformation of the main structure. When the earthquake intensity is large, the bending deformation of the second energy dissipation plate 9 increases, and through the synergistic effect of the first energy dissipation plate 3, the input of excess energy of a large earthquake can be consumed, thereby increasing the shock absorption effect of the entire building and improving the stability of the building structure.

[0029] (2) When a large earthquake occurs, the shock absorbing mechanism 10 inside the soft steel energy absorber will be acted upon by a force. At this time, the distance between the two partitions 8 will increase slightly, so that the two connecting compartments 1001 can squeeze the two connecting rods 1005, so that the connecting rods 1005 can be stretched open and the moving block 1003 can be squeezed and moved. The movement of the moving block 1003 will squeeze the internal spring 1002. The spring 1002 can reduce the deformation, thereby increasing the overall service life of the soft steel energy absorber and improving the durability of the soft steel energy absorber.
