[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an efficient installation structure for bridge steel structures, including a base 1. Multiple first support columns 2 are slidably connected inside the base 1. The base 1 has a first rectangular groove 3 and a second rectangular groove 4. The four first support columns 2 have third rectangular grooves 5 inside. The second rectangular grooves 4 communicate with the first rectangular grooves 3, providing new locking points for the limiting blocks 7 after the first support columns 2 are adjusted in position, thus switching the position of the first support columns 2. Multiple first springs 6 are fixedly connected to the inner walls of the four first support columns 2. The other end of each first spring 6 is fixedly connected to the limiting block 7. The first springs 6 have an elastic reset function, providing power for the locking action of the limiting block 7. Guide blocks 8 are fixedly connected to both sides of the limiting block 7. The guide blocks 8 communicate with the third rectangular grooves 5. The two limiting blocks 7 are fixedly connected to the outer sides of the push plate 16, which provides the operator with a force application point. By pressing the push plate 16, the first spring 6 can be compressed, causing the limiting block 7 to retract into the first support column 2. The four first support columns 2 are slidably connected to the second support column 9, which can slide within the first support column 2. The top of the second support column 9 abuts against the bridge surface 15. The limiting block 7 is slidably connected inside the first rectangular groove 3 and the second rectangular groove 4. The guide block 8 is slidably connected inside the third rectangular groove 5. The limiting block 7 is slidably connected inside the first support column 2, and the push plate 16 is slidably connected inside the first support column 2. The limiting block 7 is L-shaped, and the first rectangular groove 3 and the second rectangular groove 4 are connected.

[0033] Reference Figure 1 and Figure 4 A second spring 10 is fixedly connected inside the second support column 9. The second spring 10 provides elastic force for the popping and retraction of the pin 12. A baffle 11 is fixedly connected to the other end of the second spring 10. A pin 12 is fixedly connected inside the baffle 11. The baffle 11 connects the second spring 10 and the pin 12, transmitting the elastic force of the spring to the pin 12 and limiting the sliding stroke of the pin 12. The second support column 9 has multiple circular grooves 13 inside, and the first support column 2 has multiple circular holes 14 on its surface. The pin 12 achieves the relative position of the first support column 2 and the second support column 9 by cooperating with the circular grooves 13 and circular holes 14. The locking mechanism secures the total length of the support column. A baffle 11 is slidably connected inside the second support column 9. A pin 12 is slidably connected inside the circular groove 13, allowing the pin 12 to extend and retract within the groove, preparing for insertion or withdrawal from the circular hole 14, thus achieving length locking and unlocking. A second spring 10 is sleeved on the surface of the pin 12. The pin 12 is slidably connected inside the second support column 9, providing space for its extension and retraction. The pin 12 is slidably connected inside the circular hole 14, and the circular groove 13 and the circular hole 14 are connected, allowing the pin 12 to slide between them, achieving the locking function after the support column length is adjusted, ensuring effective length adjustment.

[0034] Working principle: When installing the first support column 2, pressure is applied to the two push plates 16 to cause the limiting block 7 to slide into the first support column 2. At this time, the first spring 6 is compressed. Then, the first support column 2 is placed into the first base 1, and the pressure on the push plates 16 is released. The first spring 6 returns to its original position, causing the limiting block 7 to engage with the first rectangular groove 3. Afterward, its position can be adjusted by sliding on the base 1 to engage with the corresponding second rectangular groove 4, simplifying the installation process and reducing the difficulty of manual operation. The first support column 2 and the second support column 9 are slidably connected, and the second spring 10 inside the second support column 9 is connected to... The baffle 11 and the pin 12 work together. When adjusting, pressing the pin 12 compresses the second spring 10, causing the pin 12 to exit the circular hole 14 of the first support column 2. The second support column 9 can then slide up and down to change its total length. Once the length is appropriate, the second spring 10 returns to its original position, and the pin 12 engages with the corresponding circular groove 13 of the second support column 9 and the new circular hole 14 of the first support column 2, locking the length. The length can be flexibly adjusted according to local settlement, avoiding the stress imbalance of the support structure caused by local settlement. There is no need for demolition and reconstruction or large-scale modification, reducing the installation rework and structural repair costs caused by settlement.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
