The support assembly 102 includes an X-shaped limiting rod 103, a limiting member 104, a limiting bolt 105, a connecting rod 106, a connecting plate 107, a connecting bolt 108, a top member 109 and a diagonal brace 116. The top member 109 includes a support cross beam 110, a top plate 111, a top column 112, a reinforcing rib 113, a blocking plate 114 and a shading plate 115. Through the foregoing solution, the problem that the existing protection shed structure is not convenient for disassembly and assembly is solved.

[0023] For this specific embodiment, the support column 101 bears the vertical load of the building and is used to support the impact force when blocking falling objects, ensuring the safety of the position covered by the support column 101.

[0024] Among them, the X-shaped limiting rod 103 is arranged on one side of the support column 101. The limiting member 104 is rotatably connected to the X-shaped limiting rod 103 and is located on one side of the X-shaped limiting rod 103. The limiting bolt 105 passes through the X-shaped limiting rod 103 and is threadedly connected to the support column 101 and is located on one side of the support column 101. The connecting plate 107 is arranged on one side of the support column 101. The connecting rod 106 is fixedly connected to the connecting plate 107 and is located on one side of the connecting plate 107. The connecting bolt 108 passes through the connecting plate 107 and is threadedly connected to the connecting rod 106 and is located on one side of the connecting rod 106. The top member 109 is arranged on one side of the support column 101. Stand multiple support columns 101 in front of the tunnel entrance. Pass the limiting bolt 105 through one end of the X-shaped limiting rod 103 and threadedly connect it to the support column 101. Then, according to the position of another support column 101, adjust the expansion angle of the X-shaped limiting rod 103. The X-shaped limiting rod 103 will be ensured to rotate during connection under the action of the limiting member 104. Then, the other end of the X-shaped limiting rod 103 is also tightened and fixed through the limiting bolt 105. And the two support columns 101 are reinforced through the connecting rod 106. Both ends of the connecting rod 106 are fixed to the connecting plate 107. The connecting bolt 108 passes through the connecting plate 107 and is threadedly tightened and fixed to the support column 101. Finally, the top is reinforced and protected by the top member 109 to prevent falling objects. The safety of use is ensured through multi-directional connection and fixation, and the assembly is carried out by means of threaded connection, which is more convenient for disassembly and secondary assembly.

[0025] Secondly, the support cross beam 110 is slidably connected to the support column 101 and is located on one side of the support column 101.

The top column 112 is fixedly connected to the support cross beam 110 and is located between the support cross beam 110 and the top plate 111. Since the support cross beam 110 is mounted on the support column 101 and is used to support the buffer force from top to bottom, only the downward positions in the front, back, left, and right directions need to be restricted. The connection through the mortise and tenon structure is convenient for disassembly and does not affect the use. The top plate 111 is installed on the support cross beam 110. The top plate 111 and the support cross beam 110 are reinforced through the top column 112, making the load-bearing capacity of the top stronger.

The top plate 111 and the support cross beam 110 are reinforced through the top column 112. Then, the reinforcing rib 113 is passed through the top plate 111 to strengthen the overall load-bearing capacity. Finally, the shielding plate 115 is laid on the surface of the reinforcing rib 113 in a triangular shape to divert the falling objects to both sides. The safety of use is ensured through multi-directional connection and fixation, and the assembly is carried out by means of threaded connection, which is more convenient for disassembly and secondary assembly.
