Description

A New Steel Column Slope Measuring Instrument

technical field

The utility model relates to a novel steel column slope measuring instrument.

Background technique

In modern steel structure buildings, more and more special-shaped steel structures are used, which causes many difficulties in the installation of steel structures. According to the requirements of Article 11.4.1 of the "Code for Construction of Steel Structure Engineering" (GB50755-2012), the inclined steel column can be measured and corrected by three-dimensional coordinate measurement method, or by the projection point of the column top combined with the elevation, and the calibration is qualified. Then it is fixed with a rigid support. For the hoisting and positioning of a special-shaped structural steel column, the traditional wire hammer method and total station measurement method cannot meet the requirements of rapid installation in terms of work efficiency and accuracy. First of all, these two measurement and calibration processes require multiple people to cooperate in the operation; second, after the measurement data is collected, it is necessary to analyze and compare the data; finally, in the adjustment process, it is usually necessary to carry out repeated measurements And adjust, so as to set up support and fix after the final adjustment is qualified. Therefore, it is necessary to invent a scientific and reasonable method that is easy and quick to implement, so that the installation of heterogeneous structural steel columns is not only easy to implement, but also can ensure the quality of subsequent installation.

The utility model has the following advantages:

1) Set two aluminum alloy angle scales in the horizontal direction, one of which is a basic angle scale, and set three bubble levelers; two bubble levelers are set on the basic angle scale along the length of the scale Two ends of the scale, another bubble leveler is perpendicular to the length direction of the scale, and is set in the middle of the basic angle scale. The other scale is a retractable angle scale, so that it is easy to carry when the instrument is not in use.

2) Set two aluminum alloy length scales along the angle direction of the steel column, and the length of the scales is 1 meter. Similarly, one of them is a basic length scale, and the other is a retractable length scale. The two length scales are equipped with magnets, so that the length scale can be adsorbed on the steel column without the support of the operator, so that the operator can level the horizontal scale.

3) Set a long angle fixed ruler at the angle between the scales in two directions, and fix the measurement angle after the horizontal angle scale is leveled.

4) In the vertical direction, a line hammer and a gravity-sensitive laser emitter are arranged at the end of the telescopic length scale for double correction.

5) Fasten the joints of the basic length scale, angle fixed scale and basic angle scale with fastening bolts to ensure the stability of the instrument during the measurement process.

The utility model provides a scientific, reasonable, and simple and fast installation slope measuring instrument for inclined steel columns, which solves the shortcomings of the traditional technology in terms of personnel operation and data collection, and improves the installation efficiency of special-shaped structural steel columns.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figures 1, 2, and 3, the utility model includes a laser transmitter 1, a wire hammer 2, a basic length scale 3, a telescopic length scale 4, a magnet 9, a basic angle scale 5, and a telescopic angle scale Ruler 6, angle fixed ruler 7, four air bubble levelers 8, are characterized in that: laser emitter 1 and wire hammer 2 are all installed on the end of stretchable length scale 4, and the other end of stretchable length scale 4 is inserted into the basic The length scale 3 is integrated, the basic length scale 3 and the retractable length scale 4 are all provided with a magnet 9, the basic length scale 3 one ends are fixed with the basic angle scale 5 one ends, and the angle fixed scale 7 is installed At the angle between the basic length scale 3 and the basic angle scale 5, one end of the telescopic angle scale 6 is inserted into the basic angle scale 5 to form a whole; three bubble levelers 8 are arranged on the basic angle scale 5, wherein Two are installed on the two ends of the basic angle scale 5 along the length direction of the scale, one is installed in the middle of the basic angle scale 5 along the direction perpendicular to the scale, and the other bubble leveler 8 is installed on the basic angle Middle of length scale 3. At the connecting nodes of the basic length scale 3 , the fixed angle scale 7 and the basic angle scale 5 , fasten them with fastening bolts 10 to ensure the stability of the instrument during the measurement process. The length of the basic length scale 3 and the flexible length scale 4 is 1 meter. The laser transmitter should have a gravity sensing function.

As shown in Figure 4, the method of using the new steel column slope measuring instrument includes the following steps:

1), after the steel column is in place, loosen the fastening bolts of the angle fixing ruler 7 of the present invention, open the measuring instrument, pull out the 4 to 2 meter scale of the stretchable length scale, the laser transmitter 1, the wire The hammer 2 is installed at the end of the retractable length scale 4, and the laser emitter 1 is turned on;

2), the two-section length scale is adsorbed on the steel column to be measured by the magnet 9, and the air bubble leveler 8 on the basic length scale 3 is used to level it to ensure the angular direction of the basic length scale 3 Consistent with the steel column;

3) According to the angle of the steel column, consider whether to use the second energy-saving telescopic angle scale 6 . Utilize the bubble leveler 8 on the basic angle scale 5 in the horizontal direction to level it to ensure that the direction of the basic angle scale 5 is horizontal, wherein the bubble leveler 8 in the horizontal direction at both ends of the basic angle scale 5 is used To control the level of the basic angle scale 5, the bubble leveler 8 perpendicular to the scale direction of the scale is used to control the verticality and twist of the basic angle scale 5;

Its principle is that, under the premise that the hypotenuse is fixed at 2 meters, the cosine formula is used to divide each point on the horizontal basic angle scale 5 Unit length, converted into its corresponding angle. In this way, the operator can quickly obtain the inclination angle of the steel column from the basic angle scale 5 without converting the measured length data, thereby greatly shortening the correction time of the steel column;

6) The purpose of setting up the hammer 2 and the gravity-sensing laser transmitter 1 is to form multiple mechanisms to check the measurement accuracy, and to cope with windy weather affecting operations;

7) There is another way to use the measuring instrument of the present utility model, which is to use reverse thinking to fix the angle of the measuring instrument with the slope of the steel column designed in advance during the process of placing the steel column, and use the existing angle To fix the steel column in place. In this way, the steel column can be placed in place quickly, and the subsequent correction work time can be saved.
