Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to an efficient measurement method for inspecting quick-release aluminum formwork systems. Background Technology

[0002] Quick-release aluminum formwork boasts advantages such as no space occupation, rapid turnover, simple operation, convenient maintenance, light weight, high rigidity, good stability, high load-bearing capacity, fewer seams, high precision, standardization, and strong versatility. Aluminum formwork construction eliminates the need for large machinery like tower cranes; vertical transportation of the formwork can be completed manually. High-quality aluminum alloy formwork can achieve a fair-faced concrete finish. Due to its numerous advantages, quick-release aluminum formwork allows for the simultaneous casting of wall and column vertical components with floor slabs and beams, resulting in fast construction and high-quality casting. Therefore, it has been widely used in the construction of reinforced concrete cast-in-place super high-rise structures for over a decade and continues to be improved upon during its application.

[0003] Currently, the inspection and measurement of quick-release aluminum formwork systems generally employ traditional methods: using a plumb line to check the verticality of the formwork, using a string line and steel ruler to measure the flatness, and using a level to check the elevation. Checking verticality, flatness, and elevation using these traditional methods typically requires three people working together, resulting in low efficiency, poor measurement accuracy, and safety hazards due to the need for inspectors to work at heights. These traditional methods are no longer sufficient to meet the requirements of rapid construction using quick-release aluminum formwork systems. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides an efficient measurement method for inspecting quick-release aluminum templates, comprising the following steps: Step 1: Prepare instruments and equipment; Step 2: Select the best location to place the total station on the floor slab of the building to be measured; Step 3: Set up the total station at the optimal location and complete the centering and leveling of the total station; Step 4: Determine the instrument elevation of the total station based on the measurement elevation baseline located on the wall or column surface of the floor to be measured; Step 5: After the total station's elevation is set, set the station for the total station. This includes inputting the total station's three-dimensional coordinates. Step 6: After the total station is set up, set the total station to rectangular coordinate measurement mode and use a mini prism to measure the coordinates of the control line of the floor to be measured to verify the correctness of the total station setting and ensure measurement accuracy. Step 7: After verifying the correctness of the total station settings, set the total station to the rectangular coordinate prism-free measurement mode, measure the rectangular coordinates of the corresponding measurement points on the template surface and record them. Repeat this process to measure the rectangular coordinates of all the column surfaces, walls, and ceiling beam template surfaces of the room to be measured. Step 8: Repeat steps 2 to 7 above to measure the rectangular coordinates of all the formwork surfaces in the room to be measured and record them. Compare the actual measured values ​​with the surface coordinates of the corresponding positions of the wall, column, and roof formwork in the design drawings to obtain the differences in position, flatness, and elevation of the wall, column, and roof formwork. Step 9: Use CAD software to mark the difference between the actual measured values ​​of the corresponding position coordinates and the theoretical coordinate values ​​of the design drawings on the drawings to form measurement results.

[0005] In a preferred embodiment, the measurement preparation includes: Based on the design drawings and positioning conditions, a rectangular coordinate system for construction surveying of the proposed building number is established. The origin of the rectangular coordinate system is outside the proposed building number, and the coordinate axes are parallel to the principal coordinate axis of the proposed building number. The planar rectangular coordinate values ​​of all walls and columns of the proposed building number within the construction coordinate system are all positive values; and Using CAD drawing software, draw a measurement plan based on the design drawings and positioning strips, and mark the rectangular coordinates of all wall and column outlines and the control lines of the floor plan to be measured on the drawing.

[0006] In a preferred embodiment, the total station is positioned in the central area of ​​the room to be measured.

[0007] In a preferred embodiment, the centering and leveling of the total station includes: a. First, mark the best location for placing the total station on the floor slab of the building to be measured; b. Fix the total station on the tripod, and use the extension and retraction of the three legs of the tripod to level the base of the total station; c. Loosen the fixing bolts of the total station and move the base of the total station horizontally so that the total station is centered again; d. Level the total station using the three adjusting bolts on the total station base; e. Repeat steps c and d above until the total station leveling is complete.

[0008] In a preferred embodiment, determining the total station's instrument elevation based on the measurement elevation baseline located on the wall or column surface of the floor to be measured includes: After completing the centering and leveling of the total station, align the total station with the reference line for measuring the elevation of the floor to be measured, and measure the height difference ΔH between the total station and the reference line. The total station elevation is calculated based on the difference between the elevation of the reference line of the floor to be measured and the elevation of the total station and the reference line of the floor to be measured. The formula for calculating the total station elevation is: H2 = H1 + ΔH.

[0009] In a preferred embodiment, setting up the total station includes: Mark the installation position of the total station with a marker, measure the vertical distance between the total station and the floor control line in the direction of two orthogonal plane control lines parallel to the main axis, and calculate the plane coordinate value of the total station based on the coordinates of the plane control lines; Input the three-dimensional coordinates of the total station; Place the miniature prism at the point on the control line of the floor to be measured, and use a total station to build the station; After the total station is set up, it is set to rectangular coordinate measurement mode, and the plane rectangular coordinates of the control line of the floor to be measured are measured to verify the correctness of the total station setup.

[0010] In a preferred embodiment, measuring the plane rectangular coordinates of the control line to be measured for the floor to be measured to verify the correctness of the total station setup includes: If the difference between the measured coordinates and the theoretical coordinates is less than or equal to 3mm, the site is considered to be correctly constructed. If the difference between the measured coordinates and the theoretical coordinates is greater than 3mm, the station setup and verification operations should be repeated.

[0011] In a preferred embodiment, the rectangular coordinate measurement of all the columns, walls, and ceiling beam template surfaces of the room to be measured in sequence includes: (1) After the total station is set up in the room to be measured and verified to be correct, set the total station to the rectangular coordinate prism-free measurement mode, and then check the centering and leveling of the total station again to ensure that the total station is centered and level. (2) Set the total station to the rectangular coordinate prism-free measurement mode, measure the rectangular coordinates of the corresponding measurement points on the template surface and record them. The measurement sequence is to measure the column surface first and then the wall surface. After the wall and column templates are measured, measure the rectangular coordinates of the side templates of the frame beam and the elevation of the bottom template of the beam. Finally, measure the elevation of the top template. The angle between the line of sight of the total station and the measurement surface is greater than 30 degrees. Specifically, when measuring wall and column formwork, the number of measurement points is based on the formwork height of the column or the formwork height of the wall; when measuring the rectangular coordinates of the side formwork of the frame beam and the elevation of the bottom formwork of the beam, the number of measurement points is based on the beam length; and when measuring the elevation of the top slab formwork, the number of measurement points is based on the floor area of ​​the room to be measured.

[0012] Compared with the prior art, the present invention has the following advantages: (1) Only one person is needed to complete the inspection of aluminum formwork elevation, position, flatness, verticality and other items, which can greatly reduce construction costs. (2) The formwork inspection is fast and efficient, which can improve efficiency by more than 40%. (3) The inspection and measurement accuracy is greatly improved. The measurement accuracy of the traditional inspection method can only reach 5mm, while the inspection and measurement accuracy of the present invention can reach 2mm. (4) The safety is high. The traditional inspection method requires the inspector to climb to a height, which poses a safety hazard. The present invention allows the inspector to quickly complete the inspection of aluminum formwork position, elevation, verticality, flatness and other items without climbing to a height, which is highly safe.

[0017] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0018] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0019] Figure 1 This is a flowchart of the method of the present invention. As shown in the figure, the efficient measurement method for inspecting the quick-release system aluminum template of the present invention includes the following steps: Step 1: Prepare instruments and equipment; the instruments include: one total station with prism-free measurement function, and one total station measuring tripod; establish a rectangular coordinate system for construction measurement of the building number to be measured according to the design drawings and positioning conditions (note: ensure that the plane position of all walls and columns of the building number to be measured has positive plane rectangular coordinate values ​​in the construction coordinate system), draw the measurement drawings according to the design drawings and positioning strips using CAD drawing software, and mark the rectangular coordinates of all walls, columns and the plane control lines of the floor to be measured; the coordinate system used in this invention is defined as follows: in the spatial rectangular coordinate system NEZ, points with equal E coordinates are on the same vertical plane parallel to the N axis, points with equal N coordinates are on the same vertical plane parallel to the E axis, and points with equal Z elevations are on the same horizontal plane; Step 2: Select the best location to place the total station on the floor slab of the floor to be measured; the floor to be measured refers to the room where the template needs to be measured. The total station should be installed in a place with good visibility, easy to carry out the measurement operation, and without any safety hazards. Step 3: Set up the total station at the optimal location and complete the centering and leveling of the total station; Step 4: Determine the instrument elevation of the total station based on the measurement elevation baseline located on the wall or column surface of the floor to be measured; Step 5: After the total station's elevation is set, set the station for the total station. This includes inputting the total station's three-dimensional coordinates. Step 6: After the total station is set up, set the total station to rectangular coordinate measurement mode and use a mini prism to measure the coordinates of the control line of the floor to be measured to verify the correctness of the total station setting and ensure measurement accuracy. Step 7: After verifying the correctness of the total station settings, set the total station to the rectangular coordinate prism-free measurement mode, measure the rectangular coordinates of the corresponding measurement points on the template surface and record them. Repeat this process to measure the rectangular coordinates of all the column surfaces, walls, and ceiling beam template surfaces of the room to be measured. Step 8: Repeat steps 2 to 7 above to measure the rectangular coordinates of all the formwork surfaces in the rooms to be measured and record them. Compare the actual measured values ​​with the surface coordinates of the corresponding positions of the wall, column, and roof formwork in the design drawings to obtain the differences in position, flatness, and elevation of the wall, column, and roof formwork. The actual measured values ​​need to be reduced by the formwork thickness. Step 9: Use CAD software to mark the difference between the actual measured values ​​of the corresponding position coordinates and the theoretical coordinate values ​​of the design drawings on the drawings to form measurement results; then evaluate the quality of the template installation according to the relevant acceptance specifications.

[0020] Further, the measurement preparation work includes: establishing a rectangular coordinate system for the construction measurement of the building to be measured based on the design drawings and positioning conditions. The origin of the rectangular coordinate system is outside the building to be measured, and the coordinate axes are parallel to the main coordinate axis of the building to be measured. The plane rectangular coordinate values ​​of all walls and columns of the building to be measured in the construction coordinate system are positive to facilitate measurement. Among them, the selected total station should have prism-free and laser-guided measurement functions, and the measurement accuracy should be above 1”, 2+2ppm. The mini prism used must be certified by a relevant testing institution. When using it, it must be set in the setting menu of the total station according to the distance constant of the mini prism certified by the testing institution. Otherwise, it will produce large measurement errors, and sometimes even major errors. And use CAD drawing software to draw the measurement plan according to the design drawings and positioning strips, and mark the rectangular coordinate values ​​of all wall and column outlines and the plane control lines of the building to be measured on the drawings.

[0021] Furthermore, the total station should be positioned in the central area of ​​the room to be measured. The total station should be installed in a location with good visibility, easy access for measurement operations, and no safety hazards. This facilitates the measurement of the rectangular coordinates of the walls, columns, and floor slab surfaces within the room.

[0022] Furthermore, completing the centering and leveling work of the total station includes: a. First, mark the best location for placing the total station on the floor slab of the building to be measured; b. Fix the total station on the tripod, and use the extension and retraction of the three legs of the tripod to level the base of the total station; c. Loosen the fixing bolts of the total station and move the base of the total station horizontally (without rotating the total station during the horizontal movement) so that the total station is centered again; d. Level the total station using the three adjusting bolts on the total station base; e. Repeat steps c and d above until the total station leveling is complete.

[0023] Figure 2 This is a schematic diagram illustrating the principle of total station elevation measurement according to the present invention. As shown in the figure, the instrument elevation of the total station is determined based on the measurement elevation baseline located on the wall or column surface of the floor to be measured, including: After completing the centering and leveling of the total station, use the total station 22 to align with the reference line 23 for measuring the elevation of the floor to be measured. Figure 2 The diagram also shows the elevation baseline 21 of the first floor (to avoid distance measurement in prism mode) and the elevation difference ΔH between the total station and the elevation baseline. The total station elevation is calculated based on the difference between the elevation of the reference line of the floor to be measured and the elevation of the total station and the reference line of the floor to be measured. The formula for calculating the total station elevation is: H2 = H1 + ΔH.

[0024] Further steps in setting up the total station include: Mark the installation position of the total station with a marker pen. Measure the vertical distance between the total station and the floor control line using a steel ruler that has been tested and approved by a relevant testing agency, in the direction of two orthogonal plane control lines parallel to the main axis. Calculate the plane coordinates of the total station based on the coordinates of the plane control lines. Input the three-dimensional coordinates of the total station (plane coordinate values ​​N and E and elevation Z), all measured in meters; Place the miniature prism at a point on the control line of the floor to be measured (the plane coordinates are known), and use a total station to establish the station based on the known coordinate method; After the total station is set up, set it to rectangular coordinate measurement mode and measure the plane rectangular coordinates of the control line of the floor to be measured to verify the correctness of the total station setup. Only after confirming that the total station setup is correct can the plane position and elevation of the template be measured.

[0025] Furthermore, the measured plane rectangular coordinates of the planned floor control lines are used to verify the correctness of the total station setup, including: If the difference between the measured coordinates and the theoretical coordinates is less than or equal to 3mm, the site is considered to be correctly constructed. If the difference between the measured coordinates and the theoretical coordinates is greater than 3mm, the station setup and verification operations should be repeated.

[0026] like Figure 3 and Figure 4 As shown, the rectangular coordinate measurements of all the columns, walls, and ceiling beam formwork surfaces in the room to be measured were completed sequentially, including: (1) After the total station is set up in the room to be measured and verified to be correct, set the total station to the rectangular coordinate prism-free measurement mode, and then check the centering and leveling of the total station again to ensure that the total station is centered and level. (2) Set the total station to rectangular coordinate prism-free measurement mode, measure the rectangular coordinates of the corresponding measurement points on the template surface and record them. The measurement sequence is to measure the column surface first and then the wall surface. After the wall and column templates are measured, measure the rectangular coordinates of the side templates of the frame beam and the elevation of the bottom template of the beam. Finally, measure the elevation of the top template. The thickness of the template should be deducted from all measured coordinate values. The angle between the line of sight of the total station and the measurement surface should be greater than 30 degrees. During the measurement, the concrete, mortar and other debris on the template surface that may affect the measurement accuracy should be cleaned. Among them, such as Figure 3 As shown, the floor to be measured has wall (column) reinforcement 31. When measuring the wall and column formwork, the measurement point (i.e., wall and column formwork measurement point 32) is... Figure 3The example shows 6 wall / column formwork measurement points. The number of measurement points is based on the formwork height of the column or the formwork height of the wall. When determining the rectangular coordinates of the side formwork of the frame beam and the elevation of the bottom formwork of the beam, the number of measurement points is based on the beam length. Figure 4 As shown, when measuring the elevation of the top slab formwork, the number of measurement points (i.e., measurement points of the top slab (top beam) formwork) is based on the floor area of ​​the room to be measured.

[0027] In a specific example, when the formwork height of a column or wall is greater than or equal to 4 meters, the coordinate values ​​of 6 points are measured on each of the two adjacent side facades of the column, and the coordinate values ​​of 9 points are measured on the wall with a length greater than 5 meters; when the formwork height of a column or wall is less than 4 meters, the coordinate values ​​of 4 points are measured on each of the two adjacent side facades of the column, the coordinate values ​​of 6 points are measured on the wall with a length greater than 5 meters, and the coordinate values ​​of 4 points are measured on the wall with a length less than or equal to 5 meters. When the beam length is greater than or equal to 6 meters, the coordinate values ​​of 6 points are measured for each side facade formwork, and the elevation of 3 points is measured for the bottom formwork. When the beam length is less than 6 meters, the coordinate values ​​of 4 points are measured for each side facade formwork, and the elevation of 2 points is measured for the bottom formwork.

[0028] For the roof slab formwork, the elevation of 9 points should generally be measured in each room. The number of measurement points for the roof slab formwork can be increased or decreased appropriately according to the size of the roof slab area of ​​the room to be measured, but the elevation measurement points for the roof slab formwork in each room should not be less than 4.

[0029] Preferably, the method of the present invention repeats steps two to eight above, measures and records the rectangular coordinates of the template surface in all rooms to be measured, and compares the actual measured values ​​(minus the template thickness) with the surface coordinate values ​​of the corresponding positions of the walls, columns, and roofs in the design drawings to obtain the construction deviation values ​​of the required inspection items such as the position, flatness, and elevation of the wall, column, and roof templates. Specifically: (1) After completing the measurement of a room in the floor to be measured according to the process of steps two to eight, the measurement work of the next room in the floor to be measured is carried out in the same way according to the process of steps two to eight until the measurement work of all rooms in the floor to be measured is completed. (2) After measuring the three-dimensional rectangular coordinates (plane rectangular coordinate values ​​and elevation) of the template surface of the wall, column, roof, and other components with a total station, the coordinate values ​​of the completed surface of the wall, column, roof, and other components are calculated after deducting the template thickness from the actual measured values. (3) After deducting the thickness of the template from the actual measured value, calculate the coordinate values ​​of the completed surfaces of the wall, column, and top plate and compare them with the design coordinate values ​​of the corresponding surfaces of the wall, column, and top plate in the design drawings. The difference is the construction deviation value of the required inspection items such as the position, flatness, and elevation of the wall, column, and top plate template.

[0030] The difference between the actual measured values ​​of the corresponding position coordinates and the theoretical coordinate values ​​on the design drawings is marked on the drawings using CAD software to form measurement results, including: (1) Mark the difference between the actual measured value of the corresponding position coordinate and the theoretical coordinate value of the design drawing on the drawing using CAD software. For wall and column components, the difference between the actual measured value and the theoretical coordinate value of the design drawing that makes the cross-section larger is a positive value, otherwise it is a negative value. The unit of measurement is millimeters. For floor slabs and other planar components, the difference between the actual measured value and the theoretical coordinate value of the design drawing that makes the elevation value larger is a positive value, otherwise it is a negative value. The unit of measurement is millimeters. (2) Evaluate the quality of the template installation according to the relevant acceptance specifications. (3) Precautions: The rectangular coordinate system used in ATOCAD drawing must be consistent with the coordinate system used in the measurement work (i.e., the coordinate axes and the origin of the coordinate system must be consistent), otherwise the installation deviation of the template cannot be measured correctly.

These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
