The working principle of the foundation pit supporting structure for building construction provided by the utility model is as follows:

when the device is not used, the two auxiliary supporting plates 8 in the contraction state ensure that the device integrally occupies less space and is convenient for people to consign and transfer;

when in use, the base 1 is firstly arranged at the approximate position close to the side wall in the foundation pit, then the push plate positioned at the lower part is lifted upwards, the push plate can drive the corresponding positioning inserted column 11 to move, finally, the positioning plate is taken out of the corresponding positioning groove 9, the corresponding tension spring 12 is in a deep compression state at the moment, then the lower auxiliary supporting plate 8 is rotated, and after the auxiliary supporting plate is rotated to be in a state of being flush with the main supporting plate 5, the two positioning grooves 9 on the connecting block 7 are replaced at the moment, then the push plate is loosened, then the corresponding positioning inserting column 11 is lowered under the resilience function of the corresponding tension spring 12 and is brought into the corresponding positioning groove 9, the tension spring 12 is in a micro-compression state at the moment, so that the auxiliary supporting plate 8 below can be clamped, then, the upper push plate is pressed downwards, the upper auxiliary supporting plate 8 can be unfolded in the same way, and the two auxiliary supporting plates 8 are in a flush state with the same main supporting plate 5;

then, the motor is started in a positive direction, an output shaft of the motor drives the rotating shaft to rotate, so that the internal threaded steel pipe 13 can be driven to rotate under the meshing of the two gears, the pressing screw 14 starts to drive the bearing plate 15, the main support guard plate 5 and the two auxiliary support guard plates 8 to move towards the direction close to the side wall of the foundation pit under the sliding limitation of the two limiting rods, the motor is continuously started until the main support guard plate 5 and the auxiliary support guard plates 8 contact the side wall, at this time, the main support guard plate 5 and the auxiliary support guard plates 8 do not move, but the bearing plate 15 still moves horizontally relative to the main support guard plate 5, so that the pressing spring 17 starts to be extruded, the pressing spring 17 is compressed under stress, and the motor is closed until the pressing spring 17 deforms to a certain degree, and then the collision degree between the main support guard plate 5 and the side wall can be deep and tight;

in the using process, if the supporting height needs to be increased, the bolt can be rotated to bring the cylinder out of the corresponding adjusting circular groove, then the four frames 3 are lifted upwards until the cylinder is lifted to the corresponding height, and the rotating bolt is clamped.

the utility model provides a building construction foundation pit supporting structure, which is characterized in that two auxiliary supporting plates 8 capable of contracting and expanding are arranged, so that the device occupies a small space when not in use, no protrusion exists, the device can be greatly convenient for people to carry out consignment and transfer, the convenience is high, moreover, through the arrangement of the arranged internal thread steel pipe 13 and the pressing screw 14, even if the mounting position of the base 1 has a slight deviation, the main supporting plate 5 and the auxiliary supporting plate 8 can be finally in close contact with the side wall, and under the action of the pressing spring 17, the contact distance between the main supporting plate and the auxiliary supporting plate is deeper, the supporting effect is improved, in addition, the supporting height of the device can be adjusted through the arrangement of the adjustable column 4, so that the device can be more suitable for the actual supporting condition, and the use is convenient.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
