DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A guardrail support structure for municipal highway bridge construction comprises a column 1, a guardrail 11 is fixedly connected to the surface of the column 1, a first mounting block 2 is snap-connected to the surface of the column 1, a first bolt 21 is perforated on the surface of the first mounting block 2, a first nut 22 is threadedly connected to the surface of the first bolt 21, the first bolt 21 is perforated and connected to the surface of the column 1, a first support rod 23 is rotatably connected to the surface of the first mounting block 2, a mounting plate 24 is fixedly connected to the surface of the first support rod 23, a second bolt 25 is perforated and connected to the surface of the mounting plate 24, a connecting plate 26 is fixedly connected to the bottom of the second bolt 25, an anchor rod 27 is fixedly connected to the bottom of the connecting plate 26, a second nut 28 is threadedly connected to the surface of the second bolt 25, the anchor rod 27 will be inserted into the soil on one side of the highway, thereby providing a support point for the first support rod 23 on the soil, the anchor rod 27 makes the horizontal height of the connecting plate 26 remain unchanged during the process of the soil surface descending, and the connecting plate 26 is used as a support point to avoid the trouble caused by the soil descending.

[0024] Furthermore, a reinforcement mechanism is provided on the surface of the first support rod 23, and the reinforcement mechanism includes a second support plate 3, the second support plate 3 is rotatably connected to the surface of the first support rod 23, a second mounting block 31 is rotatably connected to the surface of the second support plate 3, the second mounting block 31 is snap-connected to the surface of the column 1, a limiting block 32 is snap-connected to the surface of the column 1, a screw 33 is fixedly connected to the surface of the limiting block 32, and a third nut 34 is threadedly connected to the surface of the screw 33. The original support structure only supports one end of the column 1, while the reinforcement mechanism supports at the bottom of the column 1, thereby improving the stability of the column 1.

[0025] Furthermore, the first mounting block 2 is in a "U" shape, a circular hole is opened on the surface of the first mounting block 2, a circular hole is opened on the surface of the column 1, the first bolt 21 penetrates the circular holes of the first mounting block 2 and the column 1 at the same time, and the first mounting block 2 is fixedly mounted on the column 1 by the first bolt 21 and the first nut 22. At this time, the first support rod 23 can be rotated on the surface of the column 1 through the first mounting block 2, and the mounting plate 24 is rotated on the column 1 through the first support rod 23, and the mounting plate 24 is rotated to be parallel to the horizontal plane through the first support rod 23.

[0026] Furthermore, a through hole is opened on the surface of the mounting plate 24, and the second bolt 25 passes through the through hole of the mounting plate 24. The lower surface of the mounting plate 24 contacts and is connected to the upper surface of the connecting plate 26. The connecting plate 26 is also parallel to the horizontal plane, and the connecting plate 26 is on the upper surface of the soil.

[0027] Furthermore, the second bolt 25 and the anchor rod 27 are perpendicular to the surface of the connecting plate 26, and the second bolt 25 and the anchor rod 27 are on the same vertical line. The mounting plate 24 is fixedly mounted on the surface of the connecting plate 26 by the second bolt 25 and the second nut 28. The anchor rod 27 is deeply inserted into the soil. The anchor rod 27 supports the second bolt 25 through the connecting plate 26, so that the connecting plate 26 fixes the end of the first support rod 23 away from the column 1 through the mounting plate 24. The connecting plate 26 supports the column 1 through the first support rod 23. Since the connecting plate 26 will not follow the soil settlement, the stability of the support of the first support rod 23 is guaranteed.

[0028] Furthermore, the second mounting block 31 and the limit block 32 are both in a "U" shape. The second mounting block 31 and the limit block 32 are in contact and connected together. The second mounting block 31 and the limit block 32 have the same shape. There is a circular hole on the surface of the second mounting block 31. The screw 33 passes through the circular hole of the second mounting block 31. The screw 33 limits the specific position of the limit block 32 on the second mounting block 31, thereby facilitating the installation of the limit block 32 on the surface of the second mounting block 31.

[0029] Furthermore, the second mounting block 31 is fixedly mounted on the limit block 32 by means of the screw 33 and the third nut 34, and the second support plate 3 limits the specific positions of the limit block 32 and the third nut 34 on the column 1 on the first support rod 23, and the column 1 engages the second mounting block 31 on the column 1 through the limit block 32, so that the second mounting block 31 cannot continue to rotate at one end of the second support plate 3, and the other end of the second support plate 3 cannot rotate on the first support rod 23 due to the position of the second mounting block 31, so that the second support plate 3 on the first support rod 23 supports the bottom of the column 1 through the second mounting block 31, thereby improving the stability of the column 1.

[0030] Working principle: The first mounting block 2 is snap-connected to the surface of the column 1, and the first bolt 21 is then passed through the circular holes of the first mounting block 2 and the column 1 at the same time. The first nut 22 cooperates with the first bolt 21 to fix the first mounting block 2 on the column 1, and the anchor rod 27 is inserted into the bottom of the soil so that the connecting plate 26 is on the soil surface. The first support rod 23 rotates on the first mounting block 2, and the first support rod 23 drives the mounting plate 24 to rotate until it contacts and connects to the surface of the connecting plate 26. At this time, the second bolt 25 passes through the through hole on the surface of the mounting plate 24, and the second nut 28 cooperates with the second bolt 25 to install the mounting plate 24 on the surface of the connecting plate 26. Since the anchor rod 27 is deeply inserted into the bottom of the soil, the connecting plate 26 will not sink. The connecting plate 26 supports the column 1 through the first support rod 23, avoiding the first support rod 23 from failing to effectively support the column 1.

[0031] The second support plate 3 is rotated on the surface of the first support rod 23, and the second mounting block 31 is rotated on the surface of the second support plate 3, so that the second mounting block 31 can be engaged and connected to the surface of the column 1. At this time, the limit block 32 will be engaged and connected to the surface of the column 1, and the screw 33 will pass through the circular hole of the second mounting block 31. The third nut 34 will fix the limit block 32 to the second mounting block 31 through the screw 33. The limit block 32 limits the rotation of the second mounting block 31 on the second support plate 3, and the second mounting block 31 also limits the rotation of the second support plate 3 on the first support rod 23. The second support plate 3 supports the bottom of the column 1 on the first support rod 23 through the second mounting block 31 and the limit block 32, thereby improving the stability of the support for the column 1.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
