Detailed Description
The preferred embodiments of the present invention will be described with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are merely illustrative and explanatory of the present invention and do not limit the scope of the utility model in any manner.
Referring to fig. 1-4, the utility model discloses a flatness and elevation detection device for a plane cast-in-place concrete floor, which comprises an elevation detection panel 1, wherein a datum line is arranged in the middle of the elevation detection panel 1 in the horizontal direction, graduated scales 2 are symmetrically arranged on two sides of the elevation detection panel, the datum line extends to the 0-scale position of the graduated scales on the two sides, a leveling bubble 3 is arranged on any side of the bottom center Y of the elevation detection panel 1 in the direction of the bottom center, an adjustable upright rod 5 is fixedly connected under the bottom center of the elevation detection panel 1, and a base 6 is arranged at the bottom of the adjustable upright rod 5; the flatness and elevation detection device is matched with the infrared emitter for use, and the infrared emitter preferably selects a high-precision infrared level meter.
Wherein, elevation test panel 1 is the stainless steel sheet metal, and adjustable pole setting 5 is the cavity tubulose, like stainless steel pipe or square pipe, considers the connection stability to elevation test panel 1, and the diameter of pipe or the thickness of square pipe should not be less than the thickness of elevation test panel 1. The bottom of the base 6 is a stainless steel flat plate.
The adjustable vertical rod 5 comprises a fixed rod 5-2 and an extension rod 5-1, the fixed rod 5-2 is fixed on a base 6, the extension rod 5-1 is inserted into the fixed rod 5-2 from the top, the height of the adjustable vertical rod 5 can be freely adjusted by adjusting the insertion depth of the extension rod 5-1, a strip-shaped hole 5-3 is formed in the extension rod 5-1, after the adjustable vertical rod 5 is adjusted to an appropriate height, a height adjusting knob 4 penetrates through the fixed rod and is inserted into the strip-shaped hole 5-3 to fix the fixed rod 5-2 and the extension rod 5-1 in a threaded connection mode.
When the leveling instrument is used, the high-precision infrared level instrument is erected on the poured floor slab leveling surface and leveled in the process of finishing surface plastering and surface folding after concrete pouring of the floor slab. The elevation detection device is placed on a concrete surface layer to be paved, the height of the adjustable vertical rod 5 is adjusted through adjusting the depth of the extension rod 5-1 inserted into the fixed rod 5-2, so that a horizontal light beam emitted by the high-precision infrared level meter coincides with a datum line on the elevation detection panel 1, the position of the level bubble 3 is centered, then the height adjusting knob 4 penetrates through the fixed rod 5-2 to be inserted into the strip-shaped hole 5-3 to fix the fixed rod 5-2 and the extension rod 5-1 in a threaded connection mode, and the initial elevation is determined.
