Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to a template positive and negative angle deviation measuring ruler and a measuring method thereof. Background Art

[0002] The Yin-Yang angle measuring ruler is an indispensable tool for construction inspection. It can measure the angles of building walls or finished formwork to check whether the angles are vertical or meet the design standards. However, in actual use, when measuring the Yin-Yang angles of a formwork with a supporting back rib, the supporting back rib will interfere with the Yin-Yang angle measuring ruler in the prior art, making it impossible for the two scale plates of the measuring ruler to fit on the plane of the formwork, resulting in serious errors in the measurement results, making it impossible to detect the quality of the formwork and provide corresponding data support, and unable to guarantee the quality of the Yin-Yang angles after the main structure is cast.

[0003] Through the public patent search, the following public patents were found:

[0004] An automatic measuring ruler for yin and yang angles for engineering (CN207570553U) discloses an automatic measuring ruler for yin and yang angles for engineering. The traditional ruler only needs to observe with eyes during the measurement process. If the hand is not placed level, it will cause deviation in the measurement data, affecting the authenticity of the measurement. The scheme comprises: a main ruler (1), the main ruler has a cavity inside, a secondary ruler (2) is placed in the cavity, the main ruler and the secondary ruler are connected by a rotating shaft (4), an angle sensor (8) is installed above the rotating shaft, the angle sensor is connected to a display panel (9) through a wire, the display panel is connected to a micro battery (6) through a switch (5) and a wire, and the micro battery is connected to a solar charging panel (7) through a wire. The scheme is used for an automatic measuring ruler for yin and yang angles for engineering.

[0005] A square detection ruler for yin and yang angles (CN207585503U) A square detection ruler for yin and yang angles, comprising a main ruler, one end of which is rotatably connected to a sub-rule, the main ruler is provided with a level bubble and a dial, one side of the main ruler is also provided with a placement slot, the main ruler is detachably connected to a stabilizing mechanism on both sides of the wall, and the sub-rule is rotatably connected to rollers on both sides of the wall. This scheme fits the stabilizing mechanism hinged with the main ruler to the wall on one side where the yin and yang angles need to be measured, and makes the sub-rule lean on the wall on the other side. The main ruler can be easily adjusted on the wall through the stabilizing mechanism. At the same time, because the side of the sub-rule that fits the wall is provided with a roller, when the sub-rule is driven to slide on the wall surface by adjusting the main ruler, the sub-rule is subject to less resistance, and thus it is easier to adjust the measuring ruler to a horizontal position. The stabilizing mechanism can be removed and installed on the corresponding side of the main ruler according to the effect of measuring the yang angle or the yin angle.

[0006] After analysis, the above-mentioned patent is different from the present solution in structure and function, especially when used on the back of a Yin-Yang corner template with back rib support, due to the interference of the back rib, the main scale and the auxiliary scale of the detection ruler cannot be respectively fitted with the two planes of the Yin-Yang corner, and the deviation of the Yin-Yang corner cannot be accurately measured. Therefore, the problems it solves and the actual effects it achieves are different, and therefore do not affect the novelty of the present solution. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a template positive and negative angle deviation measuring ruler and a measuring method thereof, which effectively solves the problem that the positive and negative angles cannot be measured due to the supporting back ribs during the template installation process.

[0008] A template positive and negative angle deviation measuring ruler comprises a long side frame and a short side frame which are hingedly connected at the ends, wherein the long side frame and the short side frame are both penetrated and installed with a plurality of support rulers with adjustable spacing in the horizontal direction; a bubble level and a vertical bubble gauge are embedded in the long side frame, and an angle scale is formed on the top of the long side frame.

[0009] The preferred technical solution of the present invention is that a linear scale is formed on the support ruler.

[0010] The preferred technical solution of the present invention is that a plurality of fastening bolts are installed on both the long side frame and the short side frame.

[0011] A method for measuring the deviation of a template positive and negative angle measuring ruler comprises the following steps:

[0012] Step 1: Measure the spacing between the supporting back ribs of the template's internal and external corners and adjust the spacing between the supporting rulers on the long side frame and the short side frame. Adjust the supporting rulers on multiple long side frames to be parallel to each other and to have the same extended length;

[0013] Step 2: Make one end of the support ruler on the long side frame penetrate the supporting back rib of the template's positive and negative corners and support it vertically on the plane of the template. Observe the bubble level and vertical bubble gauge, and adjust the long side frame to be parallel to the template and perpendicular to the angle connecting line between the two templates.

[0014] Step 3: Adjust the connection angle between the long side frame and the short side frame according to the design angle, and the connection angle is read by the angle scale;

[0015] Step 4: Adjust the support ruler on the short side frame in turn to penetrate the supporting back ribs of the positive and negative corners of the template and support it vertically on the plane of the template. The difference in readings between the linear scales on two adjacent support rulers is the deviation value.

[0016] The advantages and economic effects of the present invention are:

[0017] The template positive and negative angle deviation measuring ruler and the measuring method thereof of the present invention can effectively avoid the interference problem of the supporting back rib on the back of the template by supporting the end of the ruler vertically on the back of the template, so that the long side frame and the short side frame of the measuring ruler can measure the positive and negative angle deviation without directly contacting the template plane; the adjusted support ruler position and the angle between the long side frame and the short side frame can be fixed by tightening bolts; the horizontality and verticality of the measuring ruler can be adjusted by a bubble level and a vertical bubble gauge; the angle data of the measuring ruler and the positive and negative angle deviation value can be read by the angle scale and the straight line scale; the measuring method of the template positive and negative angle deviation measuring ruler of the present invention can perform estimated measurement without the need for a control line, effectively reduces the error of the traditional process, can detect the template quality and provide corresponding data support, ensure the quality of the positive and negative angle after the main structure is cast, saves construction time and reduces labor costs, and has good economic and social value.

[0038] (4) Adjust the position of another support ruler on the short side frame so that the support ruler is perpendicular to and in contact with the template plane, and then read the scale difference between the two support rulers on the short side frame. This value is the numerical deviation of the positive and negative angles.

[0039] 2. Measurement method of the deviation of the positive and negative angles of horizontal components

[0040] (1) Read the angle dial and fix the angle of the square at 90° using the square fixing bolts.
