DETAILED DESCRIPTION
[0023] The present application will be further described in detail below with reference to the accompanying drawings.
[0024] The embodiment of the present application discloses a construction under-pass building passage support structure, referring to Figure 1 , including a stand column 1 and a main support frame 2 supported by the stand column 1. The main support frame 2 is provided with a support assembly 3 to play a main support role. Further, the support assembly 3 is used to support the uneven position correspondingly. The main support frame 2 is movably connected to the stand column 1. Before the stand column 1 and the main support frame 2 are removed after the construction is completed, the inner wall flatness of the passage can be further improved by hammering the main support frame 2.
[0025] Referring to Figure 1 , 2 The bottom of the main support frame 2 is fixed with an adjusting block 21, and the upper part of the stand column 1 is provided with an adjusting groove 11 for accommodating and adjusting the adjusting block 21. The adjusting block 21 is positioned at the bottom of the adjusting groove 11, and the adjusting block 21 can be lifted in the adjusting groove 11, facilitating the hammering upward movement of the main support frame 2. After the inner wall of the passage is hammered flat by the main support frame 2, the stand column 1 and the main support frame 2 are removed.
[0026] Referring to Figure 1The support assembly 3 comprises a connecting frame 31 and an abutting plate 32. The connecting frame 31 is arranged below the main support frame 2 and is matched with the main support frame 2 in shape. The abutting plate 32 is fixed on the upper part of the connecting frame 31 and penetrates the main support frame 2, so that the abutting plate 32 can abut on the uneven part of the inner wall of the passage. If necessary, the abutting plate 32 can be cut according to the need, so as to better fit the inner wall of the passage. The surface of the abutting plate 32 is arc-shaped, which can fit the inner wall of the passage and has better supporting effect.
[0027] With reference to Figure 1 The connecting frame 31 is fixed with a plurality of reinforcing ribs 311 which are radially arranged from the center of the connecting frame 31. The reinforcing ribs 311 enhance the structural strength of the connecting frame 31 and improve the supporting stability.
[0028] With reference to Figure 1 The outer side wall of the connecting frame 31 is fixed with a plurality of deformable top blocks 4 at the position opposite to the abutting plate 32. When the connecting frame 31 moves upward and the abutting plate 32 abuts on the inner wall of the passage, the top blocks 4 can abut on the inner side wall of the main support frame 2, so as to further improve the supporting stability of the main support frame 2. The surface of the top blocks 4 is arc-shaped, which can fit the inner side wall of the main support frame 2 and has better supporting effect.
[0029] With reference to Figure 1 The support assembly 3 further comprises a movable plate 33 which is connected to the column 1 through a lifting structure 5 and is fixed on both ends of the connecting frame 31. The lifting structure 5 comprises a lifting block 51 and a lifting groove 52. The lifting block 51 is fixed on the side wall of the movable plate 33, and the opposite two side walls of the lifting block 51 extend to form a fixing plate 6 which abuts on the corresponding outer side wall of the column 1. The lifting groove 52 is arranged on the side wall of the column 1, and the lifting block 51 is connected to the lifting groove 52. The side wall of the movable plate 33 is fixed with the fixing plate 6 which is positioned on the column 1 through a bolt 7, so as to adjust and position the connecting frame 31.
