Embodiment 1

[0024] Example 1 as figure 2 , image 3 As shown, eight layers of buffer components are vertically arranged in the protective outer layer 4 of this embodiment to surround the pier 8. The horizontal section of the protective outer layer 4 is circular, and each layer of buffer components includes two layers of stiffening beams 3 with horizontal rings. The beam 3 is also correspondingly annular. The buffer members 2 are evenly distributed on the upper and lower sides of the stiffening beams 3 on the two layers. In the vertical direction, the adjacent buffer members 2 are arranged alternately. The horizontal inner stiffening beam 3 is connected, the inner stiffening beam 3 is tightly hugged to the pier 8, and the shock-absorbing rubber block 5 is connected to the upper and lower adjacent inner stiffening beams 3 and riveted with the pier 8, and each layer The stiffening beams 3 of the horizontal outer layer of the buffer assembly are all fixed on the inner wall of the protectiv...

Embodiment 2

[0027] Example 2 as Figure 5 , Image 6 As shown, eight groups of buffer assemblies are arranged vertically up and down in the protective outer layer 4 of this embodiment. The horizontal section of the protective outer layer 4 is circular, and the stiffening beam 3 is also a corresponding ring shape. Each layer of buffer assemblies includes three layers of ring sleeves. Beam 3, the innermost stiffened beam 3 tightly hugs the pier 8, similar to the connection mode between the buffer member 2 and the stiffened beam 3 in Embodiment 1, the inner stiffened beam 3 and the middle stiffened beam 3 in this embodiment are buffered The members 2 are connected, and the stiffening beams 3 of the middle layer and the stiffening beams 3 of the outer layer are also connected sequentially through the buffer members 2, and the intersecting ends of the buffer members 2 are always in the outer layer; between the vertically adjacent stiffening beams 3 of the inner layer Connect the shock-absorbi...

Embodiment 3

[0028] Example 3 as Figure 8 , Figure 9 , Figure 10 As shown, the protection design is mainly designed for the structures in the intercommunication triangle area. Since the intercommunication triangle area is a diversion place for automobiles, it is easy to be hit by automobiles. Such as Figure 9 As shown, wherein the front-end protective column 9 is cylindrical, and the safety protection device arranged on it is half around the front end of the protective column 9 (that is, facing the direction in which the vehicle enters), and the protective outer layer 4 of the safety protection device is horizontally stacked. The surface is a semicircle, and each layer of buffer components in the protective outer layer 4 includes three layers of stiffening beams 3 arranged horizontally inside and outside, and the stiffening beams 3 are also corresponding semi-circular. The shock-absorbing rubber blocks 5 are connected between adjacent stiffening beams 3 , and the shock-absorbing rub...

Abstract

The invention relates to an elastic-plastic steel-structured safety protection device. At present, the strikes of automobiles and ships to bridge piers or ambitus buildings are rigid strikes, energy can not be effectively dissipated to alleviate striking damage. The safety protection device comprises an outer protection layer and buffer assemblies fixed in the outer protection layer and arranged in a vertical lamellar mode, each layer of buffer assembly comprises a stiffening girder distributed in a horizontal layer mode and a buffer structural member uniformly distributed and spanned between every two adjacent stiffening girders, each buffer structural member is a pair of arc damping spokes mutually buckled, and one end of the pair of damping spokes are mutually crossed; and the buffer structural members on the adjacent buffer assemblies are mutually crossed in a vertical direction, a damping rubber block is arranged between every two adjacent stiffening girders in the vertical direction, and the adjacent damping rubber blocks in the vertical direction are mutually crossed. The invention has the advantages of high safety, good durability, strong energy dissipation effect, simple installation and convenient maintenance.

Description

technical field [0001] The invention belongs to the technical field of structure protection in the operation of bridges and construction projects, and relates to a safety protection device, in particular to an elastic-plastic steel structure safety protection device. Background technique [0002] At present, the current situation of traffic safety in our country is worrying. There are basically no protective devices to isolate or slow down the impact of vehicles, ships and other vehicles on many key structures that affect public transportation safety, which directly threatens people's lives and property safety; however With the rapid growth of my country's traffic volume, the contradiction between cars, ships and roads or buildings around rivers has become more and more prominent. Accidents of cars and ships hitting bridge piers or surrounding buildings occur from time to time, and in severe cases, bridge piers or building structures will collapse and vehicles and ships will b...
