In the preformed hole applying device for the building engineering, the inner wall of the die tube is fixedly provided with the supporting blocks which correspond to the guide rods one by one, and the outer ends of the guide rods which correspond to the supporting blocks are hinged on the supporting blocks.
In the preformed hole constructing device for the building engineering, a holding rod perpendicular to the screw rod is fixedly arranged at the upper end of the screw rod.
In the preformed hole applying device for the building engineering, the number of the positioning frames is two, and the two positioning frames are distributed in the middle of the mold pipe at intervals.
The construction process is as follows: the sleeve is pre-embedded at the position of the reserved hole, concrete is poured outside the sleeve to be below the top opening of the mold pipe, the screw rod is rotated to the top block to abut against the bottom of the mold pipe, at the moment, the inner end of the support rod is in a downward inclination state, the inner end of the support rod is enabled to be upward inclined to have larger resistance, further, the inside of the mold pipe is enabled to have larger supporting force from inside to outside, after the concrete is solidified, the screw rod is rotated reversely, on the premise that the compression spring is compressed, the inner end of the support rod is enabled to be upward inclined, the rotating screw rod is mechanically repaired, when the pressing force of the compression spring on the guide rod is smaller, the pressing force between the mold pipe and the inner wall.
This scheme is suitable for the construction in great aperture preformed hole, the mould pipe is the plastics material, receiving under great bracing piece tension, certain deformation can take place, make the mould pipe under the prerequisite that keeps basic outline, by a small amount of external stay extension of support position, the position that is propped when making to take out the mould pipe restores and breaks away from with muddy earth, and then can be great reduction mould pipe take out the in-process and the adhesive force that mixes earth, this scheme need not carry out mantle and fat liquoring to the outer wall of mould pipe and handles. The holding rod is used for reducing external force required by rotation of the screw rod and facilitating pulling out of the die tube.
