The device can simultaneously correct the central line, the verticality and the elevation of the bolt, and has the advantages of simple structure and convenient operation.
Referring to fig. 6-9, the positioning and installation of the bolt by using the positioning device for the bolt without the wire frame comprises the following specific operation steps:
1) firstly, a positioning tool is manufactured, wherein the positioning tool comprises a triangular platform 1, a fine flat platform 2 and a cross line pendant 3, a plurality of bolt fixing devices with different grades and sizes are manufactured according to the diameter and the type number of bolts on site, a pre-embedded bolt 5 with the diameter less than or equal to 24mm is taken as an example, a round hole 22 formed in the center of the fine flat platform 2 is larger than 24mm, and a nut 42 in the center of the bolt fixing device 4 is in a nut type matched with the bolt.
2) After the cushion layer and the foundation concrete are poured or the platform bottom film is installed, according to the position of each embedded bolt 5 specified by a drawing, the position point of each bolt is marked on the cushion layer, the foundation concrete or the bottom die, a cross line can be drawn by red paint to make an obvious mark, and then the bolt position is organized for acceptance.
3) After acceptance check is qualified, the paying-off installation is waited for, and bolt position points are staggered in the construction process of the reinforcing steel bar so as to prevent the bolts from being positioned when the bolts are fixed in the later period.
4) The triangular platform 1 is placed on the foundation steel bar according to the approximate position of the bolt position point, and the support 13 at the bottom of the triangular platform 1 is adjusted to enable the flat supporting plate 11 to be stable, namely the flat supporting plate is kept horizontal and stable as much as possible. An open gap is formed in one side of the flat supporting plate 11, and a circular hole 12 in the middle of the platform is communicated with the outside, so that bolts with cranks can be conveniently installed and placed.
5) Placing a fine leveling platform on the triangular platform, placing a cross line pendant 3 on the fine leveling platform 2, clamping a cross 31 of the cross line pendant into the groove 23, enabling the line pendant 32 to be located at the center of the circular hole 22 of the fine leveling platform, slightly moving the triangular platform and adjusting the levelness of the fine leveling platform, enabling the center of the line pendant 32 to be just opposite to the position point of the bolt, and taking out the cross line pendant 3. Horizontal bubbles can be placed on the leveling platform 2 to display the levelness of the leveling platform. In this example, the levelling bench 2 is also provided with a notch 24 opening the central circular hole 22, which notch 24 is positioned in the same direction as the notch of the triangular platform 1 or at least partially coincides therewith.
6) The embedded bolt 5 is arranged in the bolt fixer 4, the square linear steel of the bolt fixer 4 is clamped in the groove 23, and the nut 42 is aligned with the range of the round hole 22; at this time, the position of the embedded bolt 5 replaces the position of the line weight in the previous step, and the position of the original line weight 32 is the position of the bolt center line.
7) Further leveling the bolt holder 4; and positioning and finely adjusting the height of the bottom end of the bolt according to the design height of the bolt to enable the bottom ends of all the embedded bolts to be at the height of the reference line, welding the bolts with the reinforcing steel bar after the bolts are vertical, and finishing the installation of the bolts.
In the method, the specific operation of bolt height positioning is as follows: firstly, a laser level meter is adopted to position a datum line according to the designed height of the bottom end of an embedded bolt 5, the height difference between a leveling platform 2 and the datum line is measured, and the length below a nut 42 is determined according to the difference when the embedded bolt 5 is screwed into a bolt fixer 4. After further leveling of the bolt fixer 4, the bottom of the embedded bolt 5 may have a small amount of deviation or inaccurate position, and the bolt needs to be slowly and slightly rotated so that the bottom ends of all the embedded bolts are at the height determined by the reference line.
The invention positions the bolt perpendicularity through the bolt fixer 4 and the leveling platform 2, and positions the bolt height through the threaded fit of the bolt and the nut and the height of the laser positioning instrument.
The leveling of both the leveling platform 2 and the bolt holder 4 can operate with reference to a level bubble disposed thereon. The leveling of the bolt fixer 4 can be realized by installing leveling line weights 43 on two linear steels which are 90 degrees from each other, the leveling line weights 43 are adjusted to finely adjust the bottom end of the bolt, the embedded bolt 5 is fixedly welded with the steel bar after being determined to be vertical, and the bolt installation is finished.
