Description

Technical Field

[0001] The present invention belongs to the technical field of formwork calculation in reinforced concrete structure engineering, and particularly relates to a method for calculating the contact area of wooden formwork. Background Art

[0002] In the field of construction engineering, the calculation of the quantity of wooden formwork is not only related to the project cost, but also affects the construction progress and quality control. Accurately calculating the contact area of wooden formwork helps to accurately estimate the quantity of wooden formwork and reduce waste in material procurement, which is of great significance for improving the construction efficiency and material utilization rate of construction projects, and at the same time provides an accurate basis for the construction cost budget.

[0003] Currently, in the construction industry, there are still some deficiencies in the calculation of the contact area of wooden formwork. First, for the sake of efficiency, wooden formwork workers may adopt different estimation methods, resulting in inconsistent calculation results; second, traditional calculation methods often rely on empirical formulas and manual writing, and are prone to errors due to human factors; in addition, traditional calculation methods do not consider the deduction relationship between different components, which also affects the accuracy of formwork quantity calculation.

[0004] In summary, the following problems exist in the current calculation of the contact area of wooden formwork: the calculation methods are not unified, the calculation accuracy is not high, and the actual construction and the relationship between components are not fully considered.

[0005] Therefore, how to provide a method for calculating the contact area of wooden formwork is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] In view of the deficiencies of the non-uniform, inaccurate and component-relationship-neglecting quantity calculation methods of wooden formwork workers, the present invention provides a method for calculating the contact area of wooden formwork. By dividing the calculation units and defining the calculation methods for column-wall and beam-slab components in the wooden formwork drawing, the formwork contact area of each surface is accurately calculated and summed up section by section in a certain order, solving the problem of inaccurate formwork quantity calculation. At the same time, by formulating the rules for dividing calculation units and deduction calculation, it also provides a calculation logic and method reference for the development of intelligent formwork quantity calculation tools.

[0007] To solve the above technical problems, the present invention includes the following technical solutions: A method for calculating the contact area of wooden formwork, the method comprising the following steps: Step S1, calculating the contact area of the wooden formwork of column-wall components: Based on the wooden formwork drawing of column-wall, divide the column-wall components into calculation units and perform primary numbering; for the separately divided units, perform secondary numbering on each surface of each wall or column section in a clockwise direction; perform tertiary numbering according to different contact objects of each surface; calculate the contact area of each surface; Step S2: Calculation of the contact area of the wooden formwork for beam-slab members: Based on the beam-slab wooden drawing, each beam member is regarded as a calculation unit and numbered one by one at the first level; for the divided beam units, in the clockwise direction, the contact surfaces of each section of the beam are numbered at the second level; for different contact objects on each surface, they are numbered at the third level; calculate the contact area of each surface; directly number the slab units to calculate the area of the rectangular bottom formwork and summarize it separately. Step S3: Summarize and output the contact areas of formworks for different units.

[0008] Further, the first-level numbering in step S1 includes: When forming an independent wall segment or column, select a rectangular segment or a special-shaped segment containing 1 to 3 rectangular segments, numbered as No. 1, No. 2, No. 3, and so on.

[0009] Further, the third-level numbering in step S1 includes: If there is no contact object, it is recorded as 0; if the contact object is a beam, it is recorded as 1; if the contact object is a slab, it is recorded as 2; if a certain surface contacts different objects, they are all numbered. For example, a No. 1 wall has 4 surfaces. According to the clockwise direction, if the second surface only contacts a beam, it is recorded as 1.2.1; if the fourth surface contacts both a beam and a slab, it is recorded as 1.4.1 and 1.4.2.

[0010] Further, the fourth-level numbering in step S1 includes: The contact surfaces are all rectangular surfaces, and the area is the product of the width and height of the contact surface. For different contact objects, different deduction methods are used for the height. When there is no contact surface, the height is taken as the slab bottom elevation at that place, that is, the storey height at that place minus the slab thickness; when the contact surface is a beam, the height is taken as the beam bottom elevation at that place; when the contact surface is a slab, the height is taken as the slab bottom elevation at that place.

[0011] Further, the first-level numbering in step S2 includes: The transverse beam is recorded as H, and the vertical beam is recorded as V. At the same time, the subsequent sequential number and the beam section size information are connected. The basis for numbering is to first select the transversely arranged beam, and then select the longitudinally arranged beam, from top to bottom and from left to right. For example, the first transversely arranged beam with a section size of 1000×1500mm is recorded as H-1-(1000×1500), and the sixth vertically arranged beam with a section size of 300×500mm is recorded as V-6-(300×500). The second-level numbering can be selected as follows: For the first beam with a section size of 1000×1500mm in the transverse arrangement and having 4 contact surfaces, the numbers are H-1-(1000×1500)-1; H-1-(1000×1500)-2; H-1-(1000×1500)-3; H-1-(1000×1500)-4, and the beam bottom is recorded as H-1-(1000×1500)-5.

[0012] Further, the three - level numbering in step S2 includes: if there is no contact object, it is recorded as 0; if the contact object is a beam, it is recorded as 1; if the contact object is a slab, it is recorded as 2; if the contact object is an opening, it is recorded as 3; if the contact object is a wall, it is recorded as 4; if a certain surface contacts different objects, numbering is carried out for all of them. Only the bottom of the beam is given a first - level number and is arranged at the end.

[0013] Further, the four - level numbering in step S2 includes: the contact surfaces are all rectangular surfaces, and the area is the product of the width and height of the contact surface. For different contact objects, different deduction methods are used for the height. When there is no contact surface, the height is taken as the beam height at that place; when the contact surface is a beam, the height is taken as the beam height of the higher beam at that place; when the contact surface is a slab, the height is taken as the beam height at that place; when the contact surface is a wall, since the calculation of column - wall members has been completed during calculation, to avoid repetition, the contact area is recorded as zero.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: The present invention provides a method for calculating the contact area of formwork. It divides the column - wall and beam - slab components in the formwork drawing into units, calculates the contact area of the formwork for each surface of the constituent units respectively, refines the calculation process, and improves the calculation accuracy. When taking the height value of the contact surface of different components, different deduction methods are used to accurately calculate the height of the component contact surface, ensuring the accuracy of the formwork area. This method optimizes the material use, helps to improve the formwork - matching and quantity - calculation accuracy; uses a standard form to summarize the contact area of the formwork of component units, provides a standardized process for area statistics, ensures the unified recording of data of similar components, and is convenient for tracing the original data when needed, which is helpful for the refined management of the formwork materials used in the project. Specific embodiments

[0015] The following further elaborates on a method for calculating the contact area of formwork provided by the present invention in combination with specific embodiments. According to the following description, the advantages and features of the present invention will be clearer.

[0016] Taking a certain two - story structure of a project as an example, this structure is a core - tube shear wall. Calculate the areas of the formwork contact surfaces of the shear walls and the beam - slab contact surfaces on this floor respectively. The steps are as follows: I. Calculation of the contact area of the formwork of shear walls (1) Number the shear - wall components, and the numbering rule is from left to right and from top to bottom (2) Select the No. 1 shear wall. Starting from the upper side and clockwise, there are a total of 6 wall surfaces. Calculate the area of each contact surface respectively. The 6 wall surfaces are numbered 1.1 - 1.6; For the 1.1 wall surface, it does not contact the floor or beam, and is recorded as 1.1.0. The surface length is 4000 mm, and the surface height is taken as the elevation of the bottom of the slab, 6450 - 130 = 6320 mm; 1.2 Wall surface, in full contact with the 1000×1500 up-turned beam, denoted as 1.2.1, with a surface length of 1000 mm and a surface height of the beam bottom elevation 7050 - 1500 = 5550 mm; 1.3 Wall surface, in contact with the beam and slab respectively. Among them, the beam contact section is denoted as 1.3.1.1, with a surface length of 200 mm and a surface height of the beam bottom 6450 - 800 = 5650 mm, and the slab contact section is denoted as 1.3.2.2, with a surface length of 2700 mm and a surface height of the beam bottom 6450 - 130 = 6320 mm; 1.4 Wall surface, in contact with the slab, beam, slab, and beam respectively. The slab contact section 1.4.1.2 has a surface length of 2700 and a surface height of the beam bottom 6450 - 130 = 6320 mm; the beam contact section 1.4.2.1 has a surface length of 200 mm and a surface height of the beam bottom 6450 - 600 = 5850 mm; the slab contact section 1.4.3.2 has a surface length of 2700 mm and a surface height of the slab bottom 6450 - 130 = 6320 mm; the beam contact section 1.4.4.1 has a surface length of 200 mm and a surface height of the beam bottom 6450 - 600 = 5850 mm; 1.5 Wall surface, in full contact with the 1100×1500 beam, denoted as 1.5.1, with a surface length of 1100 mm and a surface height of the beam bottom elevation 6450 - 1500 = 4950 mm; 1.6 Wall surface, not in contact with the floor slab and beam, denoted as 1.6.0, with a surface length of 6800 mm and a surface height of the slab bottom elevation 6450 - 130 = 6320 mm; (3) The summary of the contact area of the formwork for each wall surface of the shear wall is shown in the following table.

[0017] The calculation methods for the shear walls with other numbers are the same and will not be repeated here. Only the No. 1 wall is used as an example.

[0019] The calculation methods for the shear walls with other numbers are the same and will not be repeated here. Only the No. 1 wall is used as an example.

[0020] II. Calculation of the contact area of the beam wooden formwork (1) Number the beam components. To avoid missing beams, follow the principle of first calculating the horizontally arranged beams and then the vertically arranged beams, and the principle of from top to bottom and from left to right; (2) Take the first horizontally arranged beam in the upper left of the core tube as an example for calculation.

[0021] According to the above principles, the beam at the uppermost left end of the core tube with a size of 1000×1500mm should be calculated first, and it is numbered as: H-1-(1000, 1500), where H refers to the horizontally arranged beam, 1 behind refers to the first beam calculated according to the calculation rules, and the values in the brackets are the cross-sectional dimensions b×h of the beam. After defining the beam, still start from the upper side and calculate the contact area of each contact surface clockwise. Finally, calculate the bottom surface of the beam, and number them as H-1-(1000, 1500)-1 to 5 respectively. The contact of the same surface with the remaining beams and slabs is calculated in segments. The contact section with the wall has been considered when calculating the contact between the wall and the wooden formwork, and will not be calculated again.

[0022] For the surface of beam H-1-(1000, 1500)-1, there is no contact in the whole section, denoted as H-1-(1000, 1500)-1-0, the surface length is 5450mm, the surface height is 1500mm, and the contact area is: 5450×1500 = 8175000mm 2 。

[0023] For the surface of beam H-1-(1000, 1500)-2, the whole section contacts the wall, denoted as H-1-(1000, 1500)-2-4, no calculation is required. For unified calculation, the contact area is counted as 0.

[0024] For the surface of beam H-1-(1000, 1500)-3, the whole section contacts the opening, beam, and slab in sequence, and is considered and calculated in segments: 1) The first section contacts the opening, denoted as H-1-(1000, 1500)-3-1-3, the surface length is 2700mm, the surface height is 1500mm, and the area is 4050000 mm 2 ; 2) The second section contacts the 200×800 beam, denoted as H-1-(1000, 1500)-3-2-1, the surface length is 200mm, the maximum value of the surface height is taken as 1500mm, and the area is 300000 mm 2 ; 3) The third section contacts the slab section, denoted as H-1-(1000, 1500)-3-3-2, the surface length is 2550mm, the surface height is taken as 1500mm, and the area is 3825000 mm 2 。

[0025] H-1-(1000, 1500)-4-4 is the same as H-1-(1000, 1500)-2-4, and is counted as 0.

[0026] For the bottom surface of beam H-1-(1000, 1500)-5, b×L, b is 1000mm, L is 5450mm, and the contact area is 5450000mm 2 。

[0027] (3) The summary of the contact area of the wooden formwork on each contact surface of the beam is shown in the following table.

[0028]

[0029] According to the above principles, the remaining beams are calculated in sequence. Here, only the No. 1 horizontally arranged beam is used as an example.

[0030] In summary, the present invention provides a method for calculating the contact area of wooden formwork. The column-wall and beam-slab components in the wooden drawing are divided into units, and the contact area of the wooden formwork for each surface of the component unit is calculated separately, which refines the calculation process and improves the calculation accuracy. When taking the height values of the contact surfaces of different components, different deduction methods are used to accurately calculate the height of the component contact surface, ensuring the accuracy of the wooden formwork area. This method optimizes the material use and helps to improve the formwork matching and quantity calculation accuracy. By using a standard form, the contact area of the component unit formwork is summarized, providing a standardized process for area statistics, ensuring the unified recording of data for similar components, and facilitating the tracing of original data when needed, which helps to achieve refined management of the formwork materials used in the project.
