Problems solved by technology
[0003] There are certain defects in this method: (1) The workload of installing and removing the wire frame is large, and the construction period is affected
(2) Wire racks or steel plate molds require a lot of materials, resulting in a lot of waste of materials
(3) A lot of labor is required to install and remove the wire rack, resulting in labor waste
(4) The second pay-off of the wire rack is easy to cause error deviation. The installation of the wire rack is not straight or the collision and bending after the wire rack will cause error accumulation
(5) Workers rely too much on the management personnel to set off the line, and they cannot be installed without setting off the line
(6) There is no reliable reference for workers to self-adjust the verticality of the wire frame during installation

Embodiment 1
[0042] A bolt positioning device for a wireless frame, comprising a triangular platform 1 , a flat platform 2 , a reticle pendant 3 and a bolt holder 4 .
[0043] The triangular platform 1 includes a flat support plate 11 and a support 13, a circular hole 12 is arranged in the middle of the flat support plate 11, and the support 13 is supported on the foundation reinforcement layer. One side of the triangular platform 1 is provided with an open gap connected with the circular hole.
[0044] The surface of the fine-flat platform 2 is milled flat, and the geometric center of the surface 21 of the fine-flat platform is made with a round hole 22 slightly larger than the embedded bolt 5, and the round hole 22 is set as the center point to the due east, due west, due south, and due north Four grooves 23 extend in the direction. In this embodiment, an open gap 24 is provided at an included angle between the four positive directions of the fine-leveling platform 2 . The groove 23 of...

The invention provides a wireless frame bolt positioning device. The wireless frame bolt positioning device comprises a triangular platform, a fine leveling platform, a cross pendant and a bolt fixer,wherein the triangular platform is supported on a foundation steel bar; the center of the fine leveling platform is provided with a round hole, and the round hole is provided with a groove in an outward square direction; the cross pendant comprises a cross and a pendant; and the bolt fixer consists of a big nut and a crosswire frame. The invention also provides a bolt positioning and installing method of the wireless frame bolt positioning device. The method comprises the steps: firstly manufacturing an installing tool; drawing a cross line on a cushion layer, foundation concrete or a bottommold to mark a position point of each bolt; constructing the foundation steel bar; placing the triangular platform on the steel bar; placing the fine leveling platform on a flat supporting plate, placing the cross pendant on the fine leveling platform, moving the triangular platform, adjusting the levelness of the fine leveling platform, and taking out the cross pendant after the center of the cross pendant is right opposite to the position point of each bolt; arranging an embedded bolt into the bolt fixer, clamping the bolt fixer into the groove, and replacing the original pendant position bythe bolt; and adjusting height of the bottom end of embedded bolt according to a reference line.
Description
technical field [0001] The invention belongs to the foundation embedded bolt positioning construction technology, in particular to a wireless frame bolt positioning device and a positioning installation method. Background technique [0002] The foundation embedded bolts are fixed after the foundation reinforcement is arranged, and the positioning of the bolts still depends on the pay-off frame. The specific operation steps to complete the bolt positioning through the pay-off rack are: install the wire rack before installing the bolts, then put the wires on the wire rack, and then pull the construction line to install the bolts. Or make a steel plate or formwork mold first, and then perform positioning and installation. [0003] There are certain defects in this method: (1) the workload of installing and removing the wire frame is large, and the construction period is affected. (2) A large amount of material is required for the wire frame or the steel plate mold, etc., resu...
