Description

Detection tool

Technical Field

The invention relates to the field of measuring instruments, in particular to a tool for detecting verticality and levelness.

Background

The lattice type steel structure can be installed from bottom to top on site, can be hoisted and connected in a butt joint mode after being installed on the ground in a segmented mode, and can be hoisted and installed once after being installed on the whole ground. The frame beam can be assembled on the ground in sections and then connected in a high-altitude butt joint mode, or can be integrally assembled on the ground and then lifted and installed at one time. No matter what kind of mode of putting is put into position to the beam column adoption, must strictly control elevation, straightness that hangs down and horizontal deviation. In order to improve the installation accuracy of the steel structure, one beam column in the middle part is selected to be installed in advance. After the two groups of steel columns are hoisted, the axes and the elevations of the steel columns are retested immediately, the steel columns are stabilized by using the steel wire cables and the wind ropes after the deviation correction, and then the horizontal cross beams are installed, namely the so-called initial test point hoisting. After the beam is in place, it is connected by high-strength bolts but is not screwed down. After all the parts are fixed, the axis of the steel column is retested, and the deviation is finely adjusted. The axis of the steel column should be retested from two directions, and after the retested result is qualified, the bolts at all parts are screwed in sequence. During the tightening process, the axis of the steel column should be dynamically tracked, and once the change of the axis exceeds an allowable value, the change of the axis should be immediately adjusted. The whole bolt fastening process is carried out simultaneously by adopting a symmetrical method from the beam-column joint to the supporting and web member joint so as to reduce the accumulated error of a single side and ensure the correct installation of the steel column, and the correct installation of the steel column is a necessary prerequisite for all other installation work in the whole installation process.

At present, the steel structure installation accuracy is mainly detected through a vertical detection ruler and a horizontal detection ruler. In the process of fixing the part and after fixing the part, the part needs to be attached to the steel structure surface repeatedly through the detection ruler to measure positive and negative deviation, and soft-drawing adjustment is carried out. On one hand, the detection ruler is attached to the steel rod to measure large errors, and the operation is very inconvenient; on the other hand, the detection ruler is not easy to align with the steel pipe member, so that the measurement error is increased, and the dynamic tracking of the axis state becomes difficult.

The invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 and 2, the detection tool provided by the invention comprises a fixed block 1 and a rotary seat 2, wherein one side of the fixed block 1 is a detection contact surface, and the other side of the fixed block 1 is rotatably connected with the rotary seat 2. The detection contact surface of the fixed block 1 is generally a plane and is suitable for detecting an object with a flat surface; the detection contact surface of the fixed block 1 can also be provided with a groove, for example, a groove with a semicircular cross section, so that the detection contact surface can be stably contacted with the surface of the cylindrical object.

The detection contact surface can be directly contacted with the object to be detected, and can also be indirectly contacted with the object to be detected through a partition plate or a base plate and the like. For example, in order to facilitate the detection of the abutting surface, the abutting surface of the fixed block 1 is firmly fixed on the steel member, and the magnetic attraction block 5 is arranged on the detecting abutting surface of the fixed block 1, and the magnetic attraction block 5 is an object having a magnetic force effect, generally a magnet.

For example, referring to fig. 2, two grooves 51 are disposed on a side of the magnetic block 5 opposite to the fixed block 1, the two grooves 51 are arranged in a cross shape and are perpendicular to each other, a plane where a center line of the groove 51 is located is parallel to a plane where the detection contact surface is located, and a center line of one of the grooves 51 is parallel to a rotation axis direction of the rotating base 2 rotating around the fixed block 1. The detection of fixed block 1 is pasted the face or is inhaled the new detection that piece 5 formed and paste the face and can also set up locating piece 52 to make the detection paste and put into more easily taking one's place when waiting for the object, for example one side of piece 5 is inhaled to magnetism sets up two locating pieces 52, and two locating pieces 52 distribute in the both sides of the recess 51 of piece 5 of inhaling and lie in the edge of piece 5 of inhaling of magnetism, form the right angle between locating piece 52 and the piece 5 of inhaling of magnetism, as shown in fig. 2.
