The upper fixing plate 1 and the lower fixing plate 2 are both made of iron plates or steel plates, and the shape of the upper fixing plate 1 and the shape of the lower fixing plate 2 are rectangular. The upper fixing plate 1 and the lower fixing plate 2 are fixedly connected through a fixing piece 3, and the upper fixing plate 1 and the lower fixing plate 2 are parallel. Specifically, two fixing pieces 3 are provided, and the upper end and the lower end of each fixing piece 3 are fixedly connected with the upper fixing plate 1 and the lower fixing plate 2 respectively. The mounting 3 adopts the rectangle side pipe, and two mountings 3 adopt welded fastening, are located the left portion and the right part of upper fixed plate 1 respectively, make the interval between upper fixed plate 1 and the lower fixed plate 2 unchangeable, guarantee the roughness of upper fixed plate 1 and lower fixed plate 2 itself.
The upper surface of the upper fixing plate 1 in this embodiment is provided with four fixing pins 4, and all the fixing pins 4 are perpendicular to the upper fixing plate 1. Four fixing pins 4 are fixed to four corners of the upper fixing plate 1 by welding, respectively. All fixing pins 4 are of equal length. The fixing pin 4 serves as a reference for two purposes. Since the height of the reinforcing bars must not exceed the depth of the shear wall locating holes, the length of the fixing pins 4 is set to be the same as the locating hole depth. If the reinforcing bar is higher than the fixing pin 4, the raised portion needs to be cut off, thus functioning as a reference height. Secondly, in the process of level measurement, if the level meter cannot be directly placed on the upper surface of the upper fixing plate 1 for measurement, the level meter can be placed on two fixing pins 4 for measurement, namely, level measurement is facilitated. The measurement can also be performed by a laser level.
The lower fixing plate 2 in this embodiment is provided with four downward adjusting bolts 5, each adjusting bolt 5 is rotatably connected with the lower fixing plate 2 through threads, and all the adjusting bolts 5 are distributed along the circumferential direction of the lower fixing plate 2. Specifically, the four adjusting bolts 5 are provided, and the four adjusting bolts 5 are respectively located at four corners of the lower fixing plate 2. The upper surface of lower fixed plate 2 is equipped with four nuts 6, four adjusting bolt 5 one-to-one with four nuts 6 rotation connection, and the lower extreme of every adjusting bolt 5 runs through lower fixed plate 2. Through holes are formed in four corners of the lower fixing plate 2, nuts 6 are welded to the upper surfaces of the through holes, adjusting bolts 5 rotate in the nuts 6, and the lower ends of the adjusting nuts 6 are abutted against concrete or other objects, so that the levels of the upper fixing plate 1 and the lower fixing plate 2 are adjusted.
As shown in fig. 1 and 2, the upper fixing plate 1 and the lower fixing plate 2 are respectively provided with alignment holes 7, and all the alignment holes 7 of the upper fixing plate 1 are in one-to-one correspondence with all the alignment holes 7 of the lower fixing plate 2. Wherein the alignment holes 7 of the upper fixing plate 1 and the alignment holes 7 of the lower fixing plate 2 are respectively provided with six. Three of the six alignment holes 7 of the upper fixing plate 1 are close to one long side of the upper fixing plate 1 and are distributed at equal intervals along the long side, and the other three alignment holes 7 are symmetrically distributed on the other long side of the upper fixing plate 1. The diameter of the calibration holes 7 is 2mm, but the number of the calibration holes, the intervals between the calibration holes and how the calibration holes are distributed are all required to be consistent with the design, i.e. the distribution of the calibration holes 7 is the same as the distribution of the positioning holes, and can also be set according to the line standard. The steel bars extending out of the upper end of the shear wall pass through the calibration holes 7 of the upper fixing plate 1 and the calibration holes 7 of the lower fixing plate 2, are leveled through the adjusting bolts 5, and finally are verified by the level gauge.
