Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction, in particular to a cast-in-place concrete elevation positioning and measuring device. Background Art
[0002] Cast-in-place concrete refers to concrete that is cast on the construction site. Most buildings are built in this way. Concrete elevation refers to the distance from the concrete surface to a certain reference plane, which can be the ground or other specific reference plane. During the construction process, the allowable deviation of the elevation of cast-in-place concrete structure refers to the maximum allowable difference between the actual elevation of the concrete and the design elevation during the construction process. When locating the elevation, the traditional method is for one person to extend the head of the tape measure downward from the upper layer of the external steel pipe, align the head of the tape measure with the elevation mark of the next layer, and then another person on the upper layer pulls the tape measure to locate the elevation of the upper layer. This measurement method not only requires two team members to work at the same time, but also ensures that the tape measure cannot bend when locating the elevation. As a traditional measuring tool, the ruler has limited accuracy, which affects the result of elevation positioning. For this reason, we propose a cast-in-place concrete elevation positioning measurement device. Utility Model Content

[0010] Compared with the prior art, the utility model provides a cast-in-place concrete elevation positioning measurement device, which has the following beneficial effects:
[0011] 1. The cast-in-place concrete elevation positioning and measuring device surrounds the outer wall of the steel pipe through two groups of arc-shaped fixing parts, and then pushes the limit rod on one group of fixing plates to make the locking rod on the limit rod pass through the limit hole on the other group of fixing plates, and then rotates the limit rod to drive the locking rod to rotate, so that the limit hole and the locking rod are misaligned, so that the two groups of arc-shaped fixing parts can tightly surround the steel pipe to prevent the elevation positioning rod from falling off when the elevation is positioned. This structure has a good locking effect and ensures the stability of the elevation positioning rod when measuring the elevation.
[0012] 2. The cast-in-place concrete elevation positioning and measuring device drives the connecting shaft to rotate the adjusting gear by rotating the adjusting handle. The adjusting rack slides inside the elevation positioning rod through the rotation of the adjusting gear. During the sliding process of the adjusting rack, the positioning plate connected to the two sets of extension plates through the cross plate is driven to move, so that the measuring distance is controlled by the positioning plate relying on the scale line. When the specified distance is reached, the elevation is marked by aligning the lower positioning pointer with the steel pipe. This structure has high marking accuracy and can adapt to the elevation measurement of different floor heights. Only one person is required to complete the elevation measurement, saving labor costs.
