Description
Technical Field
The utility model belongs to the technical field of bridge construction, relates to construction of bridge pier columns, and particularly relates to a bridge pier column template installation accuracy measuring tool.
Background
After the bridge pier column template is installed, the plane position and elevation of the template are required to be measured so as to recheck the installation accuracy of the template. At present, in construction, a total station is generally adopted for measurement, at least two persons are required for cooperation, a main measurer is responsible for erecting and operating the total station, auxiliary staff supports a prism at the pier top, corresponding error sources are more, the error sources comprise leveling, station setting and reading errors of the total station, perpendicularity and stability errors of the prism, manual operation errors of each measurer and the like, and average value of data after multiple measurements is generally required, so that the time consumption is long.
Disclosure of Invention
The utility model aims to solve the problems and provide a tool for measuring the mounting accuracy of a bridge pier column template, which improves the efficiency and accuracy of the template mounting accuracy measurement.
The technical scheme of the utility model is as follows:
the utility model provides a bridge pier column template installation accuracy measuring tool which characterized in that: comprises a measuring ruler, a laser range finder and two brackets; scales are respectively arranged from the center to the two ends of the top surface of the measuring rule, level bubbles are respectively arranged at the two ends of the top surface of the measuring rule, a sleeve is welded at the center of the bottom surface of the measuring rule, the axis of the sleeve is perpendicular to the surface of the measuring rule, and a fastening bolt is arranged on the side wall of the sleeve in a penetrating manner; the upper end of the laser range finder is inserted into a sleeve at the bottom of the measuring tape and is fixed through a fastening bolt on the sleeve, and the lower end of the laser range finder is provided with a laser emitter; each bracket comprises a base, a screw rod is vertically welded on the base, a tray is movably sleeved on the screw rod, a supporting rod extends out of one side of the tray along the direction parallel to the base, and an adjusting nut is screwed on the screw rod at the bottom of the tray; the bottom surfaces of the two ends of the measuring tape are respectively supported on the supporting rods of the two brackets.
Compared with the existing total station measuring method, the method has the following advantages:
1. the operation is simple, and the measurement efficiency is high: the measuring instrument can start measuring after only leveling the air bubble of the level pipe on the measuring scale, is simpler to operate than a total station, can be operated by only one person, and saves manpower and time;
2. the measuring accuracy is high, the single operator error source is single and controllable, and the measuring accuracy of the pier column template is improved.

FIG. 2 is a schematic structural view of the bracket;
fig. 3 is a schematic view of the use state of the present utility model.
Detailed Description
As shown in fig. 1 and 2, the utility model comprises a measuring tape, a laser range finder and two brackets; scales are respectively arranged from the center to the two ends of the top surface of the measuring tape 1, level bubbles 2 are respectively arranged at the two ends of the top surface of the measuring tape 1, a sleeve 3 is welded at the center of the bottom surface of the measuring tape, the axis of the sleeve is perpendicular to the surface of the measuring tape, and a fastening bolt 4 is arranged on the side wall of the sleeve in a penetrating manner; the upper end of the laser range finder 5 is inserted into a sleeve at the bottom of the measuring tape and is fixed through a fastening bolt on the sleeve, and the lower end of the laser range finder is provided with a laser emitter; each bracket comprises a base 6, a screw rod 7 is vertically welded on the base, a tray 8 is movably sleeved on the screw rod, a supporting rod 9 extends from one side of the tray along the direction parallel to the base, and an adjusting nut 10 is screwed on the bottom of the tray on the screw rod; the bottom surfaces of the two ends of the measuring tape 1 are respectively supported on the supporting rods 9 of the two brackets.
In the structure, the height of the supporting rod 9 can be adjusted by rotating the adjusting nut 10, so that the measuring ruler is adjusted to be in a horizontal state.
As shown in fig. 3, the method for using the bridge pier template installation accuracy measuring tool is as follows:
(1) Before installing the pier column template, lofting out a pier column center point 11 on a pile foundation;
(2) After the template 12 is installed, two brackets are symmetrically placed at the top of the template along the diameter direction of the pier stud, a measuring tape 1 is erected on the supporting rods 9 of the two brackets, a laser range finder 5 at the bottom of the measuring tape is adjusted to be aligned with the center point 11 of the pier stud, and the measuring tape 1 is adjusted to be horizontal through an adjusting nut 10 on a screw rod on the two brackets;
(3) Respectively reading readings from the center point of the measuring rule to the positions, opposite to the inner wall of the template, of the two ends of the measuring rule, comparing the readings with the design radius of the pier stud, and calculating the installation deviation of the plane position of the template; if the design radius of the pier stud is 75cm, one end of the measuring ruler reads 70cm, and the other end of the measuring ruler reads 80cm, the mounting position of the template can be known to deviate by 5cm in the measuring direction;
(4) Horizontally rotating the two brackets and the measuring ruler at the top of the template by 90 degrees, repeating the steps (2) and (3), and measuring and calculating the installation deviation of the template in the other direction;
(5) The mounting height of the template is directly read from the reading of the laser range finder and is compared with the design elevation;
(6) And adjusting the plane position of the template and the height of the template according to the measurement result.
