Embodiment 1

[0030] refer to Figure 1-4 , this embodiment includes a folding bracket 1, a support plate 2 and a telescopic reinforcing rod 3, the folding bracket 1 includes a bottom strut 101, a longitudinal strut 102 and a diagonal strut 103, and the bottom strut 101 and the longitudinal strut 102 rotate through a rotating shaft Connect to fold and unfold, one end of the telescopic reinforcing rod 3 is rotationally connected with the longitudinal strut 102, when the bottom strut 101 and the longitudinal strut 102 are unfolded at 90 degrees, the diagonal strut 103 is rotated out and the other end is stretched and clamped on the The support force is formed between the bottom support rod 101 and the longitudinal support rod 102 on the bottom support rod 101. Both sides of the bottom support rod 101 are fixedly provided with mounting ears. The pit foundation is supported, and one end of two corresponding folding brackets 1 close to each other is supported and fixed by the telescopic reinforc...

Embodiment 2

[0038] refer to Figure 1-5 The difference between this embodiment and the first embodiment is that a telescopic reinforcing rod 3 is added. The telescopic reinforcing rod 3 includes an adjusting rod 301, a telescopic screw rod 302 and a limit block 303. The telescoping screw 302 is inserted into the threaded slot hole and threadedly connected with the adjusting rod 301. The ends of the adjusting rod 301 and the telescopic screw 302 are connected to the limiting block 303, and the adjusting rod 301 is connected to the limiting block 303 in rotation. The telescopic screw 302 is connected to the limiting The block 303 is fixedly connected, and the end of the bottom pole 101 away from the U-shaped groove 1011 is provided with a T-shaped limiting groove 1012, and the limiting blocks 303 at both ends of the telescopic reinforcing rod 3 are respectively snapped into two correspondingly installed folding brackets 1. Inside the T-shaped limiting slot 1012.

[0039] The limit blocks 3...

Embodiment 3

[0041] refer to Figure 6-8 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that it also includes a lateral support assembly, the lateral support assembly includes a rotating cross bar 1024 and a rotating cross bar 2 1026, and both sides of the longitudinal support rod 102 are provided with rotating slots 1023, the lower ends of the first rotating cross bar 1024 and the second rotating cross bar 1026 are respectively rotated and installed in the rotating grooves 1023 on both sides of the longitudinal strut 102. There is a fixed screw hole on the top, and the upper end of the rotating cross bar 1026 is provided with a docking groove 1027, and the docking groove 1027 is provided with a fixing bolt 1028, and the rotating cross bar 1024 and the rotating cross bar 2 1026 are rotated out of the rotating groove, and the adjacent rotation The plug-in block 1025 at the end of the first cross bar 1024 is inserted into the docking groove 1027 at the end of the...

Abstract

The invention discloses a building foundation pit construction safety supporting structure, and relates to the field of building tools. For solving the problems that the prior traditional supporting frame is low in building efficiency, difficult to disassemble and recycle and incapable of being used repeatedly, the following scheme is provided. The building foundation pit construction safety supporting structure comprises folding brackets, supporting plates and a telescopic reinforcing rod. Each folding support comprises a bottom supporting rod, a longitudinal supporting rod and an inclined supporting rod. The bottom supporting rod and the longitudinal supporting rod are rotationally connected through a rotating shaft to be folded and unfolded. One end of the telescopic reinforcing rod isrotationally connected with the longitudinal supporting rod. When the bottom supporting rod and the longitudinal supporting rod are unfolded to be in a 90-degree state, the inclined supporting rod rotates out and extends the other end of the inclined supporting rod to be clamped on the bottom supporting rod to form supporting force between the bottom supporting rod and the longitudinal supportingrod. The building foundation pit construction safety supporting structure can play a good role in supporting a pit foundation, the whole mechanism can stably support the pit foundation, the whole device can be conveniently disassembled, folded, stored and recycled, repeated use can be achieved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of construction tools, in particular to a construction safety support structure for a construction foundation pit. Background technique [0002] The pit foundation is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. If the excavation is deep and there are buildings nearby, the method of pit foundation wall support, shotcrete retaining wall method, large-scale pit foundation and even underground diaphragm wall and column-type bored pile interlocking can be used to ...
