Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a concrete thickness control instrument, including pole setting 1, horizontal pole 2 and sleeve 3, the vertical setting of pole setting 1 has seted up the external screw thread on the outer wall of pole setting 1, has seted up the internal thread on sleeve 3's the inner wall, through the mutually supporting of internal and external screw thread with sleeve 3 threaded connection in pole setting 1, horizontal pole 2 is equipped with two, the horizontal fixed connection in the both sides of pole setting 1 of two horizontal pole 2 relative to whether be used for monitoring concrete thickness after pouring satisfies the requirement.

Referring to fig. 1, specifically, a groove 4 is vertically formed in the outer wall of the vertical rod 1, the groove 4 extends along the length direction of the vertical rod 1, scale marks 5 are arranged in the groove 4, a reading window 6 is formed in the outer wall of the sleeve 3, the reading window 6 is a rectangular window, and readings in the sleeve 3 can be clearly observed through the reading window 6. In order to reduce reading errors, mark lines 7 can be symmetrically arranged on the sleeve 3 on two sides of the center of the reading window 6, and the scale lines 5 and the mark lines 7 are aligned when reading. Since the distance between the lower edge of the upright 1 and the lower edge of the cross bar 2 is the actual measured distance and the reading read at the reading window 6 is the distance between the lower edge of the upright 1 and the central axis of the cross bar 2, the starting point of the graduation line 5 is set at the lower edge of the upright 1 and the reading of the starting point is the distance of the mark line 7 of-1/2 from the lower edge of the cross bar 2, at which time the reading read in the reading window 6 is the actual distance between the lower edge of the upright 1 and the lower edge of the cross bar 2.

Before use, the height of the cross rod 2 on the upright stanchion 1 is adjusted according to the designed thickness of a floor slab, then the reading in the reading window 6 is the same as the thickness of the floor slab, the upright stanchion 1 is vertically inserted into concrete in the detection process, and if the concrete exceeds the lower edge of the cross rod 2, a scraper plate is adopted to scrape off the redundant concrete; if the concrete does not exceed the lower edge of the cross rod 2, the concrete should be continuously filled until the upper surface of the concrete and the lower edge of the cross rod 2 are located on the same horizontal plane, and the thickness of the concrete can be accurately controlled without the help of other measuring tools, so that the operation is simple and convenient.

Referring to fig. 1, pole setting 1 can be made by stainless steel pipe and forms, and in order to make things convenient for constructor smooth insert pole setting 1 into the concrete, here there is handle 8 at the upper end welded fastening of pole setting 1, then overlap on handle 8 and establish anti-skidding cover 9 to set up anti-skidding line on anti-skidding cover 9, can increase the frictional force between palm and the anti-skidding cover 9 through the anti-skidding line that sets up, make constructor more stable when gripping handle 8.

Referring to fig. 1 and 2, the diameter of horizontal pole 2 is less than the diameter of pole setting 1, and it can adopt solid round bar or square pole preparation to form, and screw 10 has been seted up to horizontal pole 2 near the one end of sleeve 3, and horizontal fixedly connected with bolt 11 on the sleeve 3, through with in the bolt 11 screw in to the screw 10 of horizontal pole 2 tip on the sleeve 3, can realize horizontal pole 2 and sleeve 3 fixed, when pouring the concrete floor of different specifications, can change the horizontal pole 2 of different length as required. In addition, when pouring the concrete floor of the same specification, for the convenience of processing, save operating time, also can adopt the welded mode directly to link horizontal pole 2 and sleeve 3 as an organic whole.

Referring to fig. 1, in order to reduce the resistance of the vertical rod 1 during insertion, a conical head 12 can be formed at the lower end of the vertical rod 1, and the end of the conical head 12 facing away from the vertical rod 1 should be a flat surface, so as to prevent the conical head 12 from damaging the template during insertion.

The utility model provides a concrete thickness control instrument has following advantage: the tool has the advantages of simple structure, easy manufacture and convenient use, can measure the thickness of concrete more accurately, and ensures the forming quality of concrete floors.
