Embodiment 1

[0028] Example 1: The measurement method for the surface flatness of concrete structures (used to reflect the surface flatness of shear walls and concrete columns within the range of storey heights) is as follows:

[0029] 1. Eligibility standard (i.e. specified threshold): 8mm;

[0030] 2. Measuring tools: 2-meter ruler, wedge-shaped feeler gauge;

[0031] 3. Measurement method and data recording:

[0032] (1) Shear wall / concealed column: select the long side wall, choose one of the two sides of the long side wall as a plane to be measured, and measure 20 planes to be measured in total;

[0033] (2) When the length of the selected wall is less than 3 meters, take the upper left corner and the lower right corner (the upper right corner and the lower left corner) of the four corners (top and root) of the same wall as the first measurement point 11. Place the ruler obliquely at a 45-degree angle, such as figure 1 As shown, use wedge-shaped feeler gauges to measure the surface...

Embodiment 2

[0036] Embodiment 2: The measurement method for the surface flatness of masonry engineering (used to reflect the surface flatness of masonry walls within the range of storey height) is as follows:

[0037] 1. Eligibility standard (i.e. specified threshold): 8mm;

[0038] 2 Measuring tools: 2-meter ruler, wedge-shaped feeler gauge;

[0039] 3. Measurement method and data recording:

[0040] (1) Each wall can be used as a plane to be measured, and walls with doors, windows, and aisle openings are preferred. Select the forehand wall as the measurement site. Cumulative actual measurement of 10 planes to be measured;

[0041] (2) When the length of the selected wall is less than 3 meters, take the upper left corner and the lower right corner from the four corners of the same wall (top and root, excluding the inclined roof brick range 24 and the lower sill range 25 of the wall) ( The upper right corner and the lower left corner) can also be taken as the first measurement point 2...

Embodiment 3

[0045] Example 3: The measurement method for the flatness of the wall surface (plastering project, reflecting the flatness of the surface of the plastered wall within the range of storey height) is as follows:

[0046] 1. Eligibility standard (i.e. specified threshold): 4mm;

[0047] 2 Measuring tools: 2-meter ruler, wedge-shaped feeler gauge;

[0048] 3. Measurement method and data recording:

[0049] (1) Each wall is used as a plane to be measured, and there are 15 planes to be measured in total. If the selected 2 suites are less than 15 planes to be measured, it is necessary to increase the number of actual measured suites.

[0050] (2) When the length of the wall is less than 3 meters, among the four corners of the top and root of the same wall, select the upper left corner and the lower right corner as the first measurement point, and place the ruler obliquely at the first measurement point at an angle of 45 degrees Measured 1 time respectively. If there is a gap betw...

Abstract

The invention relates to a method for detecting the flatness of a building surface. The method comprises the following steps: (a) selecting a plurality of to-be-measured planes; (b) taking two opposite angles of a to-be-measured plane as two first measuring points, carrying out measurement on the two first measuring points, placing a guiding rule with an angle of 45 degrees relative to the edge of the to-be-measured plane at the first measuring points, and when a point which is greater than a specified threshold exists between the guiding rule and the to-be-measured plane, recording the first measuring points as unqualified points; and (c) according to the ratio of the unqualified points, determining whether the flatness of the building surface is qualified. According to the invention, through establishing a plurality of measuring points on the building surface, and obtaining the flatness evaluation data of the building surface according to the measuring data of the measuring points, errors caused by manual operation in building evaluation are eliminated and the quality control of buildings is improved.

Description

technical field [0001] The invention relates to the field of building detection, in particular to a method for detecting the flatness of a building surface. Background technique [0002] The surface flatness of the walls and floors of the building not only affects the appearance of the building, but also has a certain influence on the stability of the decorative layer on the surface of the building. For the flatness of the surface of the building (such as walls, floors, etc.), there are clear error index data in the national standards. [0003] However, in the existing relevant national regulations, only the error index data is stipulated, and there is no clear and unified measurement method to make unified requirements for the flatness of the building surface in various projects. If different measurement methods are used, it will have a serious impact on the measurement results, which will lead to errors in the judgment of whether the product quality is qualified or not. ...
