[0002] The flatness detection of a building casting surface refers to the process of measuring and evaluating the flatness of the concrete surface after the concrete is poured. This detection is of great significance for ensuring the quality, safety and aesthetics of a building.

[0003] In the existing patent literature, a patent with a publication number of CN 217465656 U and a name of "a flatness detection device for a building surface" mainly detects flatness by converting the inclination angle. Such detection devices can only detect concrete casting surfaces with a small construction area, and they also need to be converted to detect flatness, resulting in low detection efficiency. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a flatness detection device for a building casting surface. Before the flatness detection, the paintbrush is ensured to be in contact with and flush with the detection reference line. If the line drawn by the paintbrush is between the two detection qualified lines after the detection, the flatness is qualified. It can detect large-area concrete casting surfaces, is simply installed, and does not require calculation, with higher detection efficiency.

[0005] To solve the above technical problems, the technical solution of the utility model is realized as follows:

[0006] A flatness detection device for a building casting surface includes a positioning and wiring mechanism and a flatness detection mechanism;

[0007] The positioning and wiring mechanism includes a vertically arranged pipe sleeve, and a double-tightening wire adjustment component is installed at the top of the pipe sleeve. Two mutually parallel steel wires are tensioned and fixed by the double-tightening wire adjustment component through the pipe sleeve;

[0008] The flatness detection mechanism includes a vertically arranged reference sleeve. Two groups of pulleys are rotatably installed at the top end of the reference sleeve through a first goat's horn bracket. The pulleys are placed above the steel wires and can roll along the length direction of the steel wires; a detection support rod is received and installed at the bottom of the reference sleeve, and a caster is fixedly installed at the bottom of the detection support rod; a guiding groove is opened on the side wall of the reference sleeve, a guiding block located in the guiding groove is fixed on the side wall of the detection support rod, a pen holder is fixedly installed on the outside of the guiding block, and a paintbrush is fixedly installed in the pen holder; a lifting adjustment component is installed on the side wall of the reference sleeve, and the reference sleeve is fixedly installed with a card slot through the lifting adjustment component. A detection paper card is inserted into the card slot, and a detection reference line and two detection qualified lines distributed above and below the detection reference line are arranged in the middle of the detection paper card.

[0009] By adopting the above scheme, the device ensures that the brush is in contact with and flush with the detection reference line before the flatness detection. After the detection is completed, if the line drawn by the brush is between the two qualified detection lines, the flatness is qualified. It can detect a large area of concrete casting surface, is simple to install, and does not require calculation, and has higher detection efficiency.

After the steel wire 2 passes through the wire-drawing disc 15 and the lead screw tube 16 in sequence, it abuts against the wire-drawing screw sleeve 17 through a steel ball 18 connected to the end of the steel wire 2. A first lead wire groove 19 and a second lead wire groove 20 are sequentially formed on the wire-drawing disc 15 and the lead screw tube 16, and a third lead wire groove 21 is formed on the wire-drawing screw sleeve 17.

[0045] As Figures 6 to 7 shown, a pull ring 23 is also fixedly installed on one side of the second ram's horn bracket 14, and a traction rope 24 is tied to the pull ring 23. In order to conveniently pull the whole flatness detection mechanism to slide along the steel wire 2, the staff only needs to pull the traction rope 24 forward, and the whole flatness detection mechanism can slide slowly.

A clamping groove 12 is fixedly installed on the lifting seat 26. In order to realize the lifting adjustment of the clamping groove 12, by loosening the first set screw 27, the paintbrush 11 can be brought into contact with and flush with the detection reference line, and then the lifting seat 26 can be fixed by tightening the first set screw 27.

[0048] As Figure 3 shown, the pipe sleeve 1 is inserted into a steel bar 29 in the concrete casting surface 28. At least two second set screws 30 that abut against the surface of the steel bar 29 are assembled on the side wall at the bottom end of the pipe sleeve 1. In order to facilitate the fixation of the pipe sleeve 1, it is inserted into the steel bar 29, and it can be completely fixed by tightening the second set screws 30.

[0049] Working principle of the utility model:

[0050] Before application, first insert the pipe sleeve 1 of the positioning and wiring mechanism onto the steel bar 29 in the concrete casting surface 28, and firmly fix the pipe sleeve 1 on the steel bar 29 by rotating the second adjusting screw 30; Subsequently, overlap the first lead wire groove 19, the second lead wire groove 20, and the third lead wire groove 21 in the double-tightening wire adjusting assembly, introduce the steel wire 2 into the first lead wire groove 19, the second lead wire groove 20, and the third lead wire groove 21, and rotate the hexagonal nut 22 with a wrench. At this time, the wire-pulling sleeve 17 continuously abuts against the steel ball 18, and finally the steel wire 2 is tightened to a horizontal state; Finally, place the pulley 5 of the flatness detection mechanism on the steel wire 2 tightened to a horizontal state, and place the detection paper 13 in the card slot 12. At this time, the casters 7 contact the horizontal plane of the concrete casting surface 28.

[0051] During application, adjust the height of the detection paper 13 through the lifting adjustment assembly. By loosening the first adjusting screw 27, the paintbrush 11 can be brought into contact with and flush with the detection reference line, and then the lifting seat 26 can be fixed by tightening the first fixing screw 27; Subsequently, the staff member pulls the traction rope 24 and slowly moves forward along the direction of the steel wire 2. After the detection is completed, if the scribing of the paintbrush 11 is between the two qualified detection lines, it means that the large-scale up and down movement of the detection support rod 6 has not been caused by the concrete casting surface, and the flatness is qualified; otherwise, it is unqualified. It can detect large-area concrete casting surfaces 28, is easy to install, and does not require calculation, and has a higher detection efficiency.

[0052] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
