Description

A Simple Device for Detecting Construction Thickness and Flatness of Concrete Floor Slab

technical field

The utility model relates to a detection tool used in building construction, in particular to a detection tool for detecting and controlling the thickness and surface smoothness of the concrete pouring of the floor slab of the construction project.

Background technique

With the rapid development of the construction industry, higher requirements are put forward for the quality inspection of construction projects. The thickness of floor concrete pouring and its surface smoothness are an important technical index for quality inspection. In previous constructions, it was difficult to control the thickness and surface smoothness of floor concrete pouring. Often after the concrete pouring was completed, uneven thickness and uneven surface appeared. In the current construction, there are two methods for detecting the thickness of concrete pouring and its surface smoothness: the first method is to use a 50-line rope to measure with a tape measure; the second method is to use a level to measure. The first method is easily affected by weather and human factors, and is prone to errors; the second method is to set the measurement reference on the pouring formwork of the floor slab. During the pouring process of the floor slab, the formwork of the floor slab is easy to shake , resulting in unstable erection of the level, and large errors in detection.

Contents of the invention

The utility model provides a simple device for detecting the construction thickness and flatness of concrete floors, which solves the technical problem of large detection errors existing in existing detection means.

The utility model solves the above technical problems through the following technical solutions:

A simple device for detecting the construction thickness and flatness of concrete slabs. A laser level bracket is arranged on the lower floor below, and a telescopic vertical rod is arranged on the laser level bracket. The upper end of the telescopic vertical rod is set above the upper floor formwork opening. A measuring ruler is arranged on the concrete pouring layer of the upper floor slab, and a measuring ruler level bubble is arranged on the measuring ruler; a telescopic rod level bubble is arranged on the telescopic vertical rod.

The concrete pouring layer of the upper floor slab is arranged on the upper floor slab formwork, and an upper floor slab erecting bracket is arranged between the upper floor slab formwork and the lower floor slab.

Detailed ways

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

A simple device for detecting the construction thickness and flatness of concrete slabs, comprising a lower floor 1 and an upper floor formwork opening 4, an upper floor concrete pouring layer 8 is arranged on the side of the upper floor formwork opening 4, and an upper floor formwork A laser level support 5 is provided on the lower floor 1 directly below the payout hole 4, and a telescopic vertical rod 6 is arranged on the laser level support 5, and the upper end of the telescopic vertical rod 6 is arranged above the upper floor formwork discharge hole 4, A laser level 7 is arranged at the upper end of the telescopic pole 6, a measuring ruler 9 is arranged on the concrete pouring layer 8 of the upper floor, and a measuring ruler level bubble 10 is arranged on the measuring ruler 9; Rod Level Bubble 11.

The upper floor concrete pouring layer 8 is arranged on the upper floor formwork 3, and an upper floor erecting support 2 is arranged between the upper floor formwork 3 and the lower floor 1; since the concrete of the lower floor 1 has solidified, the laser level 7 will be used for measurement. Can not be subjected to the influence of upper floor concrete pouring process on the laser level instrument support 5 that is fixed on the lower floor slab 1.

A formwork setting hole is required on each floor for the construction setting out, with a size of about 250 mm × 250 mm; a laser level bracket 5 is erected directly below the formwork setting out hole, which is supported on a flat and vibration-free ground, and can be passed through The verticality of telescopic pole level bubble 11 is adjusted telescopic pole 6. The laser level 7 is installed on the top of the telescopic pole 6, and the laser level 7 has an automatic leveling device; when in use, first draw an accurate 50 line with a tape measure; turn on the locking switch of the laser level 7, press the button to call out the horizontal line, and connect the laser and 50 lines are adjusted to overlap, and then, tighten the locking switch. Rotate the laser level instrument 7, and use the measuring ruler 9 with scale and level bubbles to measure the concrete pouring layer 8 of the upper floor slab.
