The utility model relates to the technical field of buildings, and discloses a telescopic cast-in-place pile reinforcement cage positioning device which comprises a connecting ring, the periphery of the inner ring of the connecting ring is provided with the same square groove hole, and the two sides of the inner walls of the four square groove holes are provided with moving grooves. An adjusting mechanism and a positioning mechanism are arranged in the connecting ring, the adjusting mechanism comprises four U-shaped bases fixedly connected to the periphery of the top of the connecting ring, the top of one U-shaped base is fixedly connected with a servo motor, the output end of the servo motor is sleeved with a first lead screw through a coupler, and the output end of the first lead screw is sleeved with a second lead screw through a coupler; and inner cavities of the other three U-shaped seats are rotationally connected with a second lead screw, a third lead screw and a fourth lead screw through bearings correspondingly. And through the arranged adjusting mechanism, an operator can conveniently and automatically move the positioning mechanism up and down to detect whether the reinforcement cage is in a vertical and non-inclined state or not and straighten the reinforcement cage, and therefore the using effect of the device can be effectively improved.

The plate grid forming mold of the present invention includes: a frame, a worktable, a pressing demolding mechanism, supporting side plates, a wire assembly plate, a long guide rod assembly, a short guide rod, a middle mold assembly, a side mold assembly, an end pressure plate, and a support platform. The middle mold assembly includes: a middle template and several fixed columns, with several upper through holes at the upper end of the middle template. The side mold assembly includes: a side pressure rod, an upper pressure plate, a lower pressure plate, a pin, a side pressure wheel or side pressure block, and a spring. The long guide rod assembly includes: a push rod, a long guide plate, and a push rod connector. Two long guide plates are fixed on the worktables on both sides of the side mold assembly. The push rod connector and two push rods move between the two long guide plates. The two push rods push the other side of the side pressure rod, causing the side pressure wheel or side pressure block to pass through the side through groove and press against the lead-clad aluminum wire. A material drop groove is opened in the center of the worktable. The supporting side plates move from the center of the worktable to both sides. The pressing demolding mechanism descends and inserts into the upper through holes, causing the lead-clad aluminum wire to fall from the fixed columns into the wire assembly grid of the wire assembly plate.

To provide an apparatus for manufacturing reinforcement mesh, and a spinning station therefor.SOLUTION: A spinning station of the present invention includes: a spinner head unit; an upper wire coil and a lower wire coil; a support body; feeding means; a first rod; a first guide wheel; and a cylinder unit. The first guide wheel functions as a wire brake. The cylinder unit acts on the first rod to position the first guide wheel at a first position where a part of a first wire is relatively tightened and position the first guide wheel at a second position where a part of the first wire extending between the spinner head unit and the first guide wheel is relatively loosened.SELECTED DRAWING: Figure 1

Ensuring a high level of security, particularly with regard to burglary or damage, is currently quite complex for fences, especially those covering large areas. A barred steel fence unit (10) is provided, formed from steel wire (11) arranged to form at least one barred steel mesh (12), wherein the steel wire (11) runs in several spatial directions, and intersecting steel wire sections (12.1) are bonded together to form a semi-finished product (13). According to the invention, the barred steel mesh (12) is formed from thermally hardenable steel wire, and the barred steel fence unit (10) is a hardened barred steel fence unit with a predefined minimum Rockwell hardness. This hardness is achieved by hardening the semi-finished product (13) to at least 45 HRC, such that the barred steel mesh (12) is materially resistant to external influences by means of hardening processes below 45 HRC.The present invention also relates to a bar steel mesh fence assembly (40) and to a system comprising the assembly and at least one detector unit. The present invention also relates to corresponding methods and uses.
