Example (b):
as shown in fig. 1 to 8, the oblique steel concrete column structure is shown, and includes a column body 1 and connecting members 2 disposed at two ends of the column body 1 and used for connecting with a carrier 4, where the column body 1 has a certain inclination angle, where the carrier 4 mainly refers to a component for connecting with the column body 1, such as an upright, and in an assembled state, that is, in a state where the carrier 4 and the column body 1 are assembled together, two ends of the column body 1 are respectively connected between two upright columns through the connecting members 2 (as shown in fig. 1), so that the connecting members 2 form a connecting node.
Since the structures of the two ends of the column 1 are the same, one end is taken as an example for the description of the present embodiment.
In order to prevent the column body 1 from directly falling off the carrier 4 when the connecting member 2 is directly broken or directly falls off from the carrier 4 after being subjected to a shock, in this embodiment, the column body 1 is provided with a protective member at both ends:
as shown in fig. 3, 5 and 6, the protective member includes a connecting portion 31 for fixing to the carrier 4 and a cable 32 having two ends provided on the connecting portion 31, where the connecting portion 31 may be a plate-shaped structure, and when assembled, it may be fixed to the carrier 4 by welding or may be fixed to the carrier 4 by bolts.
It should be noted that, as shown in fig. 3 and 4, the connection position of the connection portion 31 and the carrier 4 is different from the connection position of the connection member 2 and the carrier 4, in other words, the connection portion 31 and the connection member 2 are independent from each other, because the connection member 2 is connected to the column body 1, the connection member will bear the weight of the column body 1 for a long time, and is easy to break, and if the connection portion 31 is connected to the connection member 2, the connection portion 31 will be broken together when the connection member 2 is broken, and in this independent connection manner, the connection portion 31 will not bear the weight of the column body 1 under normal conditions, so as to ensure the long-term stability of the connection portion 31.
As shown in fig. 5 and 6, the side wall of the connecting portion 31 is provided with an elastic piece 33 extending to a side away from the connecting portion 31, and the elastic piece 33 is a structure having elastic capability, such as steel material, spring steel, etc.; it is an L-shaped structure and is fixed to the connecting portion 31 by welding, but it may also be fixed to the connecting portion 31 by bolting.
As shown in fig. 5-7, the cable 32 is wound around the elastic sheet 33, and the cable 32 is supported by the elastic sheet 33 to form a loop 321 at the side of the connecting portion 31; specifically, a threading opening through which the cable 32 passes is formed in the middle of the elastic piece 33, and the cable passes through the threading opening to be sleeved on the elastic piece 33, so that the cable 32 is supported by the elastic piece 33 to form a loop 321 at the side of the connecting portion 31.

As shown in fig. 4, the supporting member 5 is fixed to the column body 1 through the ring 321, i.e. the supporting member 5 is fixed to the column body 1 and passes through the ring 321.
When the node (i.e. the connecting member 2) is broken and the column body 1 falls onto the elastic sheet 33 in the falling process, the elastic sheet 33 can play a role in buffering and decelerating the concrete column by virtue of the elasticity of the elastic sheet 33, so that the falling speed and impact of the concrete column are reduced; when the column 1 is completely bent or broken by the elastic piece 33, the support member 5 is inserted into the loop 321 formed by the cable 32 during the continuous falling of the column 1, so that when the column 1 is continuously fallen, finally, the cable 32 pulls the support member 5 (i.e. the support member 5 is hung on the cable 32), and the support member 5 is fixed to the column 1, so that the column 1 is also pulled, thereby preventing the column 1 from collapsing.
It should be noted that the elastic pieces 33 not only serve to buffer the falling of the column 1, but also serve to support the cable 32 to form the loop 321, so as to ensure that the supporting member 5 can be directly inserted into the loop 321 when the column 1 is assembled. In other words, if the elastic piece 33 does not support the cable 32, the cable 32 will directly fall due to its own flexibility, and will not form a large loop 321; during subsequent assembly, both guarantee that rope 32 is taken in and accomodates groove 11, guarantee again when wearing to establish support piece 5, support piece 5 wears to establish in ring 321, so just need when wearing to establish support piece 5, stretch into to accomodate groove 11 with the hand and manually strut rope 32 and open so as to form a circle, then penetrate support piece 5 in this circle again, it is very inconvenient to see from this operation.
In this embodiment, as shown in fig. 3, the specific structure of the connecting member 2 is: the connecting member 2 includes a connecting seat 21 for connecting with the carrier 4, a bottom of the connecting seat 21 extends downward to form a mounting seat 212, the mounting seat 212 is for connecting with the carrier 4, and specifically, when assembling, the mounting seat 212 is mounted on the side wall of the carrier 4 through the fourth bolt 22.
