Abstract
The utility model discloses a hemispherical prism support of cellular type counter-force terrace is surveyed and control to accuracy specifically does: the center of the plane of the hemispherical base is vertically connected with the prism rod, and the circular level is fixed on the plane of the hemispherical base through the connecting rod; the round level is parallel to the plane of the hemispherical base, and the connecting rod is perpendicular to the plane of the hemispherical base. The utility model has simple structure, good universality, low installation requirement and simple use and operation; the hole type counter-force terrace loading hole is not provided with a measuring mark position, and the device is used for carrying out accurate positioning measurement on the hole type counter-force terrace, so that the position of a measuring positioning point is fixed at the central position of the loading hole at each time, and accurate measurement and control of the installation position of the hole type counter-force terrace can be effectively completed.
Description
Technical Field
The utility model belongs to forced centering device among the measuring equipment especially relates to a hemispherical prism support of accurate observing and controlling cellular type counter-force terrace.
Background
The loading counter-force system is an important test loading facility in a structural laboratory, is used for providing a fixed end for a test piece, a structural model, a counter-force frame, a loading actuator and the like and bearing a counter-force, and is particularly important in the seismic performance test research of civil engineering. Concrete structure reaction system comprises vertical reaction wall and level to reaction terrace two parts usually, and both longitudinal reinforcement link up, form wholly, the combined operation.
The counter-force terrace, also called counter-force pedestal, includes various forms such as cellular counter-force terrace and slot type counter-force terrace. The hole type counter-force terrace is characterized by that its pedestal self-body is formed into box-type structure, so that its rigidity is greater, and on the top plate of box-type structure a series of holes (loading holes) are set along longitudinal and transverse directions so as to fix counter-force frame.
When the hole type counter-force terrace is installed, the hole type counter-force terrace is generally pre-assembled firstly, a plurality of loading holes are connected into a rectangular one-screen combination in a spot welding mode according to the designed interval, and the hole type counter-force terrace is continuously positioned and installed according to the one-screen loading hole combination. The loading hole is not provided with a remarkable position which can be used as a measuring mark, and the existing base and the prism device cannot be directly used for accurate positioning measurement, so that a special measuring device is necessary to be designed for accurately measuring and controlling the position of the loading hole, thereby ensuring the fixed measuring position of the loading hole and the repeatability of multiple measurements, and further completing the accurate measurement and control of the hole type counter-force terrace.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hemispherical prism support of cellular type counter-force terrace is observed and controled to the accuracy for the loading hole position is observed and controled to the accuracy, thereby guarantees loading hole measuring position fixed and repetitious survey's repeatability, so that accomplish the accurate of cellular type counter-force terrace and observe and control.
The utility model discloses a hemispherical prism support of accurate measurement and control cellular counter-force terrace, the positive center of hemispherical base plane is connected with the prism pole vertically, the round level gauge is fixed on the hemispherical base plane through the connecting rod; the round level is parallel to the plane of the hemispherical base, and the connecting rod is perpendicular to the plane of the hemispherical base.
When the plane of the hemispherical base is in a horizontal state, the bubble of the circular level is centered.
Furthermore, the radius of the hemispherical base is slightly smaller than that of the loading hole.
The utility model has the advantages of:
the utility model has simple structure, good universality, low installation requirement and simple use and operation; the hole type counter-force terrace loading hole is not provided with a measuring mark position, and the device is used for carrying out accurate positioning measurement on the hole type counter-force terrace, so that the position of a measuring positioning point is fixed at the central position of the loading hole at each time, and accurate measurement and control of the installation position of the hole type counter-force terrace can be effectively completed.
Drawings

Fig. 2 is a top view of the utility model.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a hemispherical prism support of cellular type counter-force terrace is observed and controled to accuracy is shown as figure 1, figure 2: the right center of the plane of the hemispherical base 1 is vertically connected with the prism rod 2, and the circular level 4 is fixed on the plane of the hemispherical base 1 through the connecting rod 3; the round level 4 is parallel to the plane of the hemispherical base 1, and the connecting rod 3 is perpendicular to the plane of the hemispherical base 1.
The support is characterized in that:
1. when circular level bubble 5 was in the state of centering, 1 plane of hemisphere base was in the horizontality, and 2 axis of prism pole this moment are in vertical state, and installation prism back prism center and 1 centre of sphere of hemisphere base are on same plumb line promptly.
2. The diameter of the hemispherical base 1 can be customized according to the diameter of the loading hole so as to adapt to different field conditions.
Use the utility model discloses when the device is measured, install the prism on prism pole 2 standardly earlier, then place this support on the loading hole of four angular positions in each screen loading hole, adjust hemisphere base 1 after that and make round level bubble 5 in the middle, even the support is in the horizontality, at this moment, 2 axis of prism pole and the coincidence of loading hole axis, and the prism center is located this axis. And finally, accurately measuring the hole type counter-force terrace by using a total station and calculating by adjustment to obtain the accurate position of the center of the loading hole so as to realize accurate measurement and control of the hole type counter-force terrace.
