Detailed Description

As shown in fig. 1 to 4, the portable adjustable wall steel bar positioning device 100 of the present invention includes a vertical tube 10, a plurality of positioning cross bars 20 are movably inserted into the vertical tube 10 from top to bottom at equal intervals, and the distance between two adjacent positioning cross bars 20 is consistent with the row distance of the horizontal steel bar 300, wherein: the positioning cross rod 20 is divided into a smooth section 21 and a threaded section 22, and the length of the threaded section 22 is far greater than that of the smooth section 21; the end part of the positioning cross bar 20 at the smooth section 21 is hinged with an end nut 30, and the end nut 30 is welded with a fixing clamp 40 with a U-shaped section; the threaded section 22 of the positioning cross rod 20 penetrates through the vertical pipe 10, an adjusting nut 60 and a locking nut 50 are movably screwed on the threaded section 22, the adjusting nut 60 and the locking nut 50 are respectively arranged on two sides of the vertical pipe 10, the adjusting nut 60 and the end nut 30 are arranged on the same side of the vertical pipe 10, and the adjusting nut 60 is welded with an adjusting clamp 70 with a U-shaped cross section.

In actual manufacturing, the fixing jig 40 and the adjusting jig 70 are formed by bending steel sheets. Referring to fig. 1, for example, the fixing jig 40 and the adjusting jig 70 may be bent into a U-shaped right-angle shape corresponding to the diameter of the horizontal reinforcing bars 300, so that the horizontal reinforcing bars 300 can be stably fixed and smoothly released in the fixing jig 40 and the adjusting jig 70. Referring to fig. 1, the fixing jig 40 and the adjusting jig 70, which have U-shaped cross sections, have their openings facing outward, and the fixing jig 40 and the adjusting jig 70 have the same size.

In the present invention, the positioning rail 20 is a non-full threaded solid steel circular tube, wherein the end nut 30 drives the fixing fixture 40 to rotate around the end of the positioning rail 20.

In actual manufacture, the retention bar 20 is made of a non-fully threaded bolt without a bolt head.

In actual fabrication, the upright square tube 10 is made of a square steel tube.

As shown in fig. 1, the adjusting nut 60 and the adjusting fixture 70 are flush with each other at a side facing the vertical pipe 10, so that the adjusting nut 60 and the adjusting fixture 70 can be closely attached to the side wall of the vertical pipe 10 together, thereby improving the accuracy of positioning the space between the horizontal bars 300.

In practical implementation, after the distance between the fixing fixture 40 and the adjusting fixture 70 is determined, the thickness of the wall protection layer is determined.

In practical use, the two portable adjustable wall steel bar positioning devices 100 of the present invention are usually used to adjust the position of the wall steel bar, so as to realize positioning.
