Technical Field

The present invention relates to a scaffold frame for the construction of the surface used to specify the standard of the cut soil surface during earthwork, or to check the inclination of the cut soil surface, more specifically, the horizontal angle and the slope is installed in a circular protractor so that the angle adjustable By providing a scaffolding framework, it is possible to check the gradient of the cut soil surface and to simply specify the criteria of the cut soil surface.

Background of the Invention

In general, when the earthwork is carried out to form a cut soil surface for stability, when installing the screed frame, after measuring the designed slope slope, install the screed frame as shown in (a) to (bar) of Figure 1, The cut soil works according to the slope.

The four installation methods are widely used, and the method is described below in order.

First, the surveyor and the side are mobilized to determine the location of the top and bottom points of the light drill or the tracer on the end line (put the words) and then measure the height using the level gauge. Mark the inclined surface to be installed by connecting each material.

Second, the survey is conducted in the same way as the first, and only one point of the upper and lower positions of the longitudinal line is pinched and the inclined plane is marked according to the design gradient using the level and the horizontal ruler.

Third, after marking a number of angles inside the basic frame of the right triangle shape and installing the weight to make the basic frame, and using the weight of this basic frame to align the vertical, the second method is displayed in parallel with the slope.

In the fourth method, a method of displaying slopes after measuring the horizontal distance and the vertical direction using a horizontal ruler and a triangle is used.

(A) to (bar) of FIG. 1 show various embodiments of the installation of the scaffold, (a) is the case where the scaffold is installed at the bottom of the slope, (b) is the state where the scaffold is installed at the top of the slope, C) is the case where two horses are used, (d) is the case where poles are installed at the top and bottom horses, (e) is the case where the top and bottom horses are connected with strings, and (bar) is the distance between the height and the slope Is displayed.

Conventional frame installation method as described above has a number of problems as follows.

The problem that installation of screed frame is possible only when surveyor and side are mobilized, and the error that occurs due to the skill and skill of installing the screed frame is big, and the condition for installing the screed frame is different depending on the terrain condition or the process of earthwork. In addition, the problem of inconvenient detection is easy, and in the horizontal section on the straight section and the vertical section, it is easy to install the scaffolding frame, but the aberration manual work of the minimum 5M interval is required in the curved section on the plane and the inclined section on the longitudinal section.

In addition, after the installation of the screed frame, the actual inspection is impossible except for the survey engineer. Regardless, there is an administrative waste that requires surveyors and skilled workers to be mobilized each time.

After installation of the first scaffold frame, the installation position of the scaffold frame is often damaged due to the carelessness of the equipment or the worker, but it is impossible to confirm the work, and it is found at the time when the work is mostly completed. (Rebuild) has various problems, such as ambiguous input cost analysis, which tends to neglect managers and workers.
