Description

Technical Field

[0001] The present invention relates to the field of foundation pit components, and particularly to a method, system and terminal for calculating the welding points of the batten plates of a battened four - limb lattice column in a foundation pit. Background Art

[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plan dimensions. Affected by groundwater and the soil quality of the foundation pit wall, it is usually necessary to set a support structure in the foundation pit. For a relatively long foundation pit wall, on the basis of setting the support structure, it is necessary to add lattice columns to support the support structure to improve the anti - deformation ability of the support structure and ensure the stability of the foundation pit.

[0003] There are many types of lattice columns, and the battened four - limb lattice column is the most commonly used. During the production process of the battened four - limb lattice column, workers find the welding positions of each batten plate according to the design drawings, and then use welding equipment such as welding torches to weld the batten plates to each angle steel to form a lattice column.

[0004] Regarding the above - mentioned related technologies, the inventor believes that there are likely to be deviations between the actual dimensions of the angle steel and the dimensions of the angle steel in the design drawings. Determining the positions of each batten plate according to the design drawings is likely to cause a large deviation between the actual welding position of the batten plate and the designed position, affecting the quality of the lattice column. Summary of the Invention

[0005] In order to help improve the accuracy of the welding position of the batten plate and thus improve the quality of the lattice column, the present invention provides a method and a welding method for calculating the welding points of the batten plates of a battened four - limb lattice column in a foundation pit.

[0006] In the first aspect, a method for calculating the welding points of the batten plates of a battened four - limb lattice column provided in this application adopts the following technical solutions:

[0007] A method for calculating the welding points of the batten plates of a battened four - limb lattice column in a foundation pit includes:

[0008] Obtaining the design specification parameters of the designed angle steel and the design welding parameters of the designed batten plates in the lattice column drawing;

[0009] Obtaining the actual specification parameters of the actual angle steel;

[0010] Based on the design specification parameters of the designed angle steel and the actual specification parameters of the actual angle steel, obtaining the length difference and width difference between the designed angle steel and the actual angle steel;

[0011] Based on the design welding parameters, the length difference and the width difference, and in combination with the preset coordinate system, outputting the actual welding point coordinates of the actual batten plate.

[0012] By adopting the above technical solution, after obtaining the design specification parameters and the actual specification parameters, the length difference and the width difference are obtained, and the actual welding point coordinates are obtained based on the length difference, the width difference, and the design welding parameters. Among them, since a preset coordinate system is used, during the welding of the batten plates by the worker, a coordinate system can be equivalently obtained, and the output actual welding point coordinates are marked on the actual angle steel, which helps to improve the accuracy of the welding position of the batten plates.

[0013] Optionally, the design specification parameters include the design length and the design width; the actual specification parameters include the actual length and the actual width;

[0014] The steps of obtaining the actual specification parameters of the actual angle steel include:

[0015] Based on the design specification parameters, search the database for the actual specification parameters that are the same as the design specification parameters, and retrieve the retrieved actual specification parameters and the corresponding angle steel numbers;

[0016] When the number of the retrieved angle steel numbers is less than four, search the database a second time for the actual specification parameters with the smallest difference from the design specification parameters, and retrieve the actual specification parameters and the corresponding angle steel numbers obtained from the second search, so that the total number of the retrieved angle steel numbers is equal to four;

[0017] Obtain the actual specification parameters that are the same as the design specification parameters and the four angle steel numbers, or obtain the actual specification parameter with the smallest actual length among the four actual specification parameters and the corresponding four angle steel numbers.

[0018] By adopting the above technical solution, the database stores the actual specification parameters of each actual angle steel and the corresponding angle steel numbers. It is scientific and reasonable to give priority to using the actual angle steel with the same design specification parameters as the design angle steel, which helps to improve the quality of the lattice column. If the number of actual angle steels with actual specification parameters equal to the design specification parameters is less than four, then retrieve the actual angle steels with the smallest difference, which helps to reduce the deviation between the actual welding position of the batten plate and the design welding position, and thus helps to improve the accuracy of the welding position of the batten plate.

[0019] Optionally, the steps of searching the database a second time for the actual specification parameters with the smallest difference from the design specification parameters include:

[0020] Search the database for the actual specification parameters with the actual length equal to the design length; if any, consider the corresponding actual specification parameters to have the smallest difference from the design specification parameters, and at the same time eliminate the search sequence;

[0021] If not, search in the database for the actual specification parameters whose actual width is equal to the designed width and whose actual length is greater than the designed length; if any, consider the corresponding actual specification parameters to have the smallest difference from the designed specification parameters, and at the same time eliminate the search sequence.

[0022] If not, search in the database for the corresponding actual specification parameters whose actual length is greater than the designed length and whose difference between the actual length and the designed length is the smallest.

[0023] By adopting the above technical solution, the influence of the actual width on the welding position of the batten plates is less than that of the actual length. Therefore, when there are no actual specification parameters in the database that are the same as the designed specification parameters, it means that there are no angle steels in the field with actual specification parameters exactly the same as the designed specification parameters. At this time, search in the database for the actual specification parameters whose actual length is equal to the designed length, which is convenient for reducing the negative impact on the welding position of the batten plates due to the difference between the actual size of the angle steel and the designed size of the angle steel. In addition, after there are no actual specification parameters in the database with the actual length equal to the designed length, search for the actual specification parameters whose actual width is equal to the designed width but whose actual length is greater than the designed length; this makes the overall size of the produced lattice column not become smaller, which is convenient for meeting the usage requirements and also convenient for welding a sufficient number of batten plates on the actual angle steel, improving the quality of the lattice column.

[0024] Optionally, after obtaining the actual specification parameters that are the same as the designed specification parameters and the four angle steel numbers, the following steps are further included:

[0025] Based on the coordinate system, taking the actual specification parameters that are the same as the designed specification parameters as the reference, output the length deviation value, width deviation value, and the corresponding angle steel number of the actual specification parameters corresponding to the other three angle steel numbers compared with the actual specification parameters used as the reference.

[0026] After obtaining the actual specification parameter with the smallest actual length among the four actual specification parameters and the corresponding four angle steel numbers, the following steps are further included:

[0027] Based on the coordinate system, taking the actual specification parameter with the smallest actual length as the reference, output the length deviation value, width deviation value, and the corresponding angle steel number of the actual specification parameters corresponding to the other three angle steel numbers compared with the actual specification parameters used as the reference.

[0028] By adopting the above technical solution, the output length deviation value, width deviation value, and the corresponding angle steel number are convenient for subsequent specification correction of the corresponding actual angle steel, making the specifications of the four actual angle steels the same, which helps to improve the quality of the lattice column.

[0029] Optionally, the welding parameters include the adjacent angle steel spacing, the number of batten plates, the adjacent design spacing between adjacent batten plates, the head design spacing between the head batten plate and the head of the design angle steel, the tail design spacing between the tail batten plate and the tail of the design angle steel, the first design edge distance and the second design edge distance from the two edges of the batten plate to the corresponding edges of the design angle steel;

[0030] The step of outputting the actual welding point coordinates of the actual batten plate based on the design welding parameters, the length difference and the width difference, and in combination with the preset coordinate system includes:

[0031] Retrieve the preset coordinate system; the coordinate system is a two-dimensional coordinate system;

[0032] Taking the origin of the coordinate system as the starting point and the actual length as the spacing, generate actual length coordinate points along the Y-axis direction; taking the origin of the coordinate system as the starting point and the actual width as the spacing, generate the first actual width coordinate points along the X-axis direction; generate the first actual plane model of the actual angle steel based on the origin, the actual length coordinate points and the first actual width coordinate points;

[0033] Obtain the second actual width coordinate points and the third actual width coordinate points based on the adjacent angle steel spacing and the actual width; generate the second actual plane model based on the actual length coordinate points, the second actual width coordinate points and the third actual width coordinate points;

[0034] Obtain the number of the adjacent design spacings based on the number of the batten plates;

[0035] Obtain the total adjacent design spacing based on the adjacent design spacing and the number of the adjacent design spacings;

[0036] Obtain the total length design spacing based on the total adjacent design spacing, the head design spacing and the tail design spacing;

[0037] Obtain the head design proportion based on the total length design spacing and the head design spacing;

[0038] Obtain the tail design proportion based on the total length design spacing and the tail design spacing;

[0039] Obtain the actual head spacing based on the head design proportion, the length difference and the head design spacing;

[0040] Obtain the actual head ordinate based on the actual head spacing and the actual length coordinate points, and obtain the first actual head abscissa based on the first design edge distance and the width difference; obtain the first actual head coordinate point based on the actual head ordinate and the first actual head abscissa;

[0041] Obtain the second actual starting point coordinates based on the third actual width coordinate point, the second design margin, the width difference, and the actual starting point ordinate;

[0042] Obtain the actual end spacing based on the end design ratio, the length difference, and the end design spacing;

[0043] Obtain the actual end ordinate based on the actual end spacing, and obtain the first actual end coordinates based on the actual end ordinate and the first actual starting point abscissa;

[0044] Obtain the second actual end coordinates based on the third actual width coordinate point, the second design margin, the width difference, and the actual end ordinate.

[0045] By adopting the above technical solution, the starting point design ratio, that is, the ratio of the starting point design spacing to the total length design spacing, and the actual starting point spacing obtained based on the starting point design ratio, the length difference, and the starting point design spacing are obtained in equal proportion. Similarly for the actual end spacing, which helps to ensure the welding position accuracy of the starting point batten plate and the end batten plate, thereby helping to improve the quality of the lattice column, and facilitating the lattice column to meet the usage requirements. It is not easy to cause the actual starting point spacing or the actual end spacing to be too large due to the dimensional deviation between the actual angle steel and the designed angle steel.

[0046] Optionally, after obtaining the second actual end coordinates based on the third actual width coordinate point, the second design margin, the width difference, and the actual end ordinate, it further includes:

[0047] Obtain the adjacent design ratio based on the adjacent design spacing and the total length design spacing;

[0048] Obtain the actual adjacent spacing based on the adjacent design ratio, the length difference, and the adjacent design spacing; obtain the batten plate width based on the actual adjacent spacing, the first actual end coordinates, the first actual starting point coordinates, the number of adjacent design spacings, and the number of batten plates;

[0049] Output the first side corner coordinates of each batten plate based on the first actual end coordinates, the batten plate width, and the actual adjacent spacing;

[0050] Output the second side corner coordinates of each batten plate based on the second actual end coordinates, the batten plate width, and the actual adjacent spacing.

[0051] By adopting the above technical solution, the corner coordinates of each batten plate are calculated and output. Before the worker welds the batten plate, the corner coordinates of each batten plate can be marked on the corresponding actual angle steel. On the one hand, it helps to improve the welding position accuracy of the batten plate, and on the other hand, it helps to detect the batten plates with unqualified dimensions and improve the quality of the lattice column.

[0052] Optionally, after obtaining the actual specification parameters identical to the design specification parameters and the four angle steel numbers, or obtaining the actual specification parameter with the minimum actual length among the four actual specification parameters and the corresponding four angle steel numbers, the following steps are further included:

[0053] Based on the angle steel numbers corresponding to the actual specification parameters identical to the design specification parameters, or based on the angle steel numbers corresponding to the actual specification parameter with the minimum actual length among the four actual specification parameters, search for the corresponding manufacturers in the database;

[0054] Draw a manufacturer curve graph and a manufacturer statistical graph based on the found manufacturers.

[0055] By adopting the above technical solutions, the manufacturer curve graph facilitates knowing which manufacturer's angle steel is used for each lattice column. After problems occur in the lattice column, it is convenient to find the corresponding manufacturer, thereby reducing the angle steel produced by this manufacturer, so as to improve the quality of the lattice columns produced later. The manufacturer statistical graph facilitates knowing the manufacturers with high precision control of angle steel specifications, thus easily discovering manufacturers with good production quality and easily improving the quality of lattice columns. High precision control of the specifications of lattice columns helps to improve the precision of the welding positions of the batten plates.

[0056] In a second aspect, a batten plate welding point calculation system for a foundation pit batten type four - limb lattice column provided by the present application adopts the following technical solutions:

[0057] A batten plate welding point calculation system for a foundation pit batten type four - limb lattice column includes a first acquisition module for acquiring the design specification parameters of the design angle steel and the design welding parameters of the design batten plates in the lattice column drawing;

[0058] A second acquisition module for acquiring the actual specification parameters of the actual angle steel;

[0059] A calculation module for obtaining the length difference and width difference between the design angle steel and the actual angle steel based on the design specification parameters of the design angle steel and the actual specification parameters of the actual angle steel;

[0060] A coordinate generation module for outputting the actual welding point coordinates of the actual batten plates based on the design welding parameters, the length difference, the width difference, and in combination with the preset coordinate system.

[0061] By adopting the above technical solution, the first acquisition module acquires the design specification parameters of the designed angle steel, and the second acquisition module acquires the actual specification parameters of the actual angle steel. Through the calculation of the calculation module, the length difference and the width difference are obtained. Then, through the coordinate generation module, the actual welding point coordinates of the actual batten plate are output in combination with the welding parameters, the length difference, and the width difference. When welding the batten plate, the worker welds the batten plate according to the actual welding point coordinates, which helps to improve the accuracy of the welding position of the batten plate and avoid welding according to the designed welding position of the batten plate when there is a deviation between the size of the actual angle steel and the size of the designed angle steel, thereby reducing the quality of the lattice column.

[0062] In a third aspect, a batten plate welding point calculation terminal for a foundation pit batten plate type four - limb lattice column provided by the present application adopts the following technical solution:

[0063] A batten plate welding point calculation terminal for a foundation pit batten plate type four - limb lattice column includes a memory and a processor, and a computer program capable of being loaded and executed by the processor for the above - mentioned method is stored in the memory.

[0064] By adopting the above technical solution, it is possible to store and process the corresponding program, which is convenient for improving the accuracy of the welding position of the batten plate, thereby improving the quality of the lattice column.

[0065] In a fourth aspect, a storage medium provided by the present application adopts the following technical solution:

[0066] A storage medium stores a computer program capable of being loaded and executed by a processor for the above - mentioned method.

[0067] By adopting the above technical solution, it is possible to store the corresponding program, which is convenient for improving the accuracy of the welding position of the batten plate, thereby improving the quality of the lattice column.

[0068] In summary, based on the actual specification parameters and the design specification parameters, the length difference and the width difference are obtained, and then based on the length difference and the width difference, the actual welding point coordinates of the actual batten plate are obtained, which is convenient for the worker to weld the batten plate with reference to the actual welding point coordinates, reducing the deviation degree between the actual welding position of the batten plate and the designed position, helping to improve the accuracy of the welding position of the batten plate, and thus helping to improve the quality of the lattice column.

[0076] An embodiment of the present application discloses a method for calculating the welded joints of the batten plates of a pit battened four - limb lattice column. It should be noted that, referring to Figure 1 , the lattice column includes four angle steels j and several batten plates k, and the cross - section of each angle steel j is L - shaped. Therefore, each angle steel j has a length and two widths. Among them, in order to improve the quality of the lattice column, the two widths of the angle steel j are equal, that is, in Figure 1 , g1 = g2. In addition, the four angle steels j are in a symmetric structure, and each angle steel j is connected to the adjacent angle steel j through a batten plate. Therefore, each batten plate is welded to two angle steels j.

[0077] Referring to Figure 2 , the method for calculating the welded joints of the batten plates of a pit battened four - limb lattice column includes:

[0078] S100. Obtain the design specification parameters of the design angle steel and the design welding parameters of the design batten plates in the lattice column drawing.

[0079] For the convenience of understanding, referring to Figure 3 , the design specification parameters of the design angle steel include the design length g0 and the design width g1; the design welding parameters of the design batten plates include the adjacent angle steel spacing L1, the number of batten plates, the adjacent design spacing L2 between adjacent batten plates, the first - end design spacing L3 between the first - end batten plate and the first - end of the design angle steel, the tail - end design spacing L4 between the tail - end batten plate and the tail - end of the design angle steel, the first design edge distance L5 from the two edges of the batten plate to the corresponding edge of the design angle steel, and the second design edge distance L6.

[0080] Among them, the number of batten plates is the number of batten plates to be welded between two angle steels. Multiplying the number of batten plates by 4 can obtain the total number of batten plates used in the entire lattice column, that is, the total number of batten plates. The first - end batten plate is the batten plate welded at the top of the two angle steels; the tail - end batten plate is the batten plate to be welded at the bottom of the two angle steels.

[0081] It is not difficult to understand that the design specification parameters and the design welding parameters both exist in the design drawings of the lattice column and can be obtained through drawing recognition software or manual input.

[0082] Refer to Figure 2 , S200, to obtain the actual specification parameters of the actual angle steel.

[0083] The actual specification parameters include the actual length and the actual width.

[0084] Specifically, the steps of S200 include:

[0085] S210, based on the design specification parameters, search in the database for the actual specification parameters that are the same as the design specification parameters, and retrieve the found actual specification parameters and the angle steel numbers corresponding to the actual specification parameters.

[0086] It should be noted that the actual specification parameters of each actual angle steel to be used are stored in the database, and each set of actual specification parameters in the database corresponds to a unique angle steel number. Workers can find the corresponding actual angle steel through the angle steel number. For example, the actual specification parameters of angle steel numbers 1 to 100 are stored in the database. If the actual specification parameters of angle steel number 30, its actual length is equal to the design length and its actual width is equal to the design width, then it is considered that the actual specification parameters are the same as the design specification parameters. At this time, retrieve the actual specification parameters and the angle steel number 30.

[0087] Since each lattice column requires four angle steels, during the search, the search will not stop when one is found, but will stop when four actual specification parameters are found, and the angle steel numbers corresponding to the four actual specification parameters are all different. That is, after the retrieved actual specification parameters and the corresponding angle steel numbers are retrieved, the actual specification parameters and the corresponding angle steel numbers are deleted from the database.

[0088] S220, when the number of retrieved angle steel numbers is less than four, search in the database for the actual specification parameters with the smallest difference from the design specification parameters for the second time, and retrieve the actual specification parameters and the corresponding angle steel numbers obtained from the second search to make the total number of retrieved angle steel numbers equal to four.

[0089] It is not difficult to understand that if the number of retrieved angle steel numbers is less than four, it proves that the number of actual specification parameters equal to the design specification parameters in the database is less than four. That is, the number of available actual angle steels that meet the design specification parameter requirements is less than four. At this time, search in the database for the second time until the total number of retrieved angle steel numbers is equal to four.

[0090] Among them, the steps of S220 include:

[0091] S221. Search the database for actual specification parameters with an actual length equal to the designed length. If any are found, consider the corresponding actual specification parameters to have the smallest difference from the designed specification parameters, and at the same time, eliminate the search sequence.

[0092] It is not difficult to understand. For example, if the actual length of the actual specification parameters with angle steel number 33 in the database is equal to the designed length, then consider the actual specification parameters corresponding to angle steel number 33 to have the smallest difference from the designed specification parameters. The search sequence is automatically generated during the second search. Just sort the actual specification parameters stored in the database according to the corresponding angle steel numbers.

[0093] If there are no actual specification parameters in the database with an actual length equal to the designed length, then execute S222. Search the database for actual specification parameters with an actual width equal to the designed width and an actual length greater than the designed width. If any are found, consider the corresponding actual specification parameters to have the smallest difference from the designed specification parameters, and at the same time, eliminate the search sequence.

[0094] For example, during the second search, except for the actual specification parameters corresponding to angle steel number 33 that satisfy the condition that the actual length is equal to the designed length, other actual specification parameters do not meet this condition, and the number of angle steel numbers retrieved at this time is less than four. Then search the database for actual specification parameters with an actual width equal to the designed width and an actual length greater than the designed width. If the actual specification parameters corresponding to angle steel number 66 meet the condition, then consider them to have the smallest difference from the designed specification parameters. Those with the smallest difference will be retrieved. If the number of angle steels retrieved at this time is equal to four, stop the second search. If it is less than four, continue the second search.

[0095] If there are no actual specification parameters in the database with an actual width equal to the designed width and an actual length greater than the designed width, then execute S223. Search the database for the corresponding actual specification parameters with an actual length greater than the designed length and the smallest difference between the actual length and the designed length. Consider the corresponding actual specification parameters that meet the conditions to have the smallest difference from the designed specification parameters, and at the same time, eliminate the search sequence. The second search continues until the number of retrieved angle steel numbers reaches four.

[0096] S230. Obtain the actual specification parameters that are the same as the designed specification parameters and four angle steel numbers, or obtain the actual specification parameter with the smallest actual length among the four actual specification parameters and the corresponding four angle steel numbers.

[0097] After the first search and / or the secondary search, a total of four actual specification parameters and four angle steel numbers are retrieved. Each angle steel number corresponds to an actual specification parameter, facilitating workers to find the corresponding available actual angle steel by the angle steel number. When obtaining the actual specification parameters, only the actual specification parameter that is the same as the design specification parameter or has the minimum actual length among the four retrieved actual specification parameters is obtained. This is to facilitate the calculation of the actual welding point coordinates of the actual batten plates. When calculating, the actual welding points of the batten plates can be calculated by combining the actual specification parameters of the substitute actual angle steel, and it can ensure that the actual welding points obtained from the four angle steels are symmetrical, and the actual batten plates are not prone to skew after being welded according to the actual welding point coordinates.

[0098] To ensure that the actual specification parameters of the four actual angle steels are the same, after step S230, it further includes step S240. Based on the coordinate system, taking the actual specification parameter that is the same as the design specification parameter as the benchmark, output the length deviation value, width deviation value, and the corresponding angle steel number of the actual specification parameters corresponding to the other three angle steel numbers compared with the actual specification parameter used as the benchmark. Or based on the coordinate system, taking the actual specification parameter with the minimum actual length as the benchmark, output the length deviation value, width deviation value, and the corresponding angle steel number of the actual specification parameters corresponding to the other three angle steel numbers compared with the actual specification parameter used as the benchmark.

[0099] Briefly speaking, step S240 is to facilitate workers to know the length deviation and width deviation between the four retrieved actual specification parameters, so as to facilitate workers to cut or grind three of the four actual angle steels to make the actual specification parameters of the four actual angle steels the same. As for which one of the four actual specification parameters to use as the benchmark, it needs to combine the specific situation of the four retrieved actual specification parameters. If there is an actual specification parameter that is the same as the design specification parameter among the four actual specification parameters, then take the actual specification parameter that is the same as the design specification parameter as the benchmark to trim the actual specification parameters of the other three actual angle steels; if there is no actual specification parameter that is the same as the design specification parameter among the four actual specification parameters, then according to the rule of the secondary search, take the actual specification parameter with the minimum actual length as the benchmark to facilitate the trimming of the actual specification parameters of the other three actual angle steels.

[0100] It should be noted that whether or not it is necessary to trim the actual specification parameters of the four actual angle steels to be the same, outputting the deviation values between the four actual specification parameters helps workers understand the differences between the four actual specification parameters, so as to judge whether the four actual angle steels can be used. If it exceeds the design standard or design specification of the lattice column, it is convenient for workers to adjust the actual angle steel in time.

[0101] S250. Based on the angle steel number corresponding to the actual specification parameters that are the same as the design specification parameters, or based on the angle steel number corresponding to the actual specification parameter with the smallest actual length among the four actual specification parameters, search for the corresponding manufacturer in the database; draw a manufacturer curve graph and a manufacturer statistical graph based on the found manufacturer.

[0102] For the sake of easy understanding, the corresponding angle steel number mentioned in step S250 refers to the angle steel number corresponding to the actual specification parameter used as the benchmark. The database stores the manufacturers of angle steel, and each manufacturer corresponds to a number of angle steel numbers, meaning that the actual angle steel corresponding to the angle steel number is produced by this manufacturer. Find the corresponding manufacturer according to the angle steel number, and draw a manufacturer curve graph and a manufacturer statistical graph. Among them, the abscissa of the manufacturer curve graph is time, that is, the time when the actual angle steel of the corresponding manufacturer is used, and the ordinate is the name of each manufacturer; after problems occur with the angle steel of the lattice column, the corresponding angle steel manufacturer can be found according to the production time of the lattice column, which helps to avoid using the angle steel of this manufacturer in the later stage and helps to ensure the quality of the lattice column. The manufacturer statistical graph is the number of times that the angle steel produced by each manufacturer has been selected as the benchmark since the production of the lattice column, which is convenient for workers to select manufacturers with high production accuracy.

[0103] Refer to Figure 2 , after step S200, it further includes step S300. Based on the design specification parameters of the designed angle steel and the actual specification parameters of the actual angle steel, obtain the length difference and width difference between the designed angle steel and the actual angle steel.

[0104] It is not difficult to understand that since when obtaining the actual specification parameters of the actual angle steel, one is selected from the four retrieved actual specification parameters, only one length difference and one width difference will be obtained when calculating the length difference and width difference.

[0105] S400. Based on the design welding parameters, length difference and width difference, and in combination with a preset coordinate system, output the actual welding point coordinates of the actual batten plate.

[0106] In combination with a preset coordinate system, draw two angle steel models in the coordinate system according to the actual specification parameters. Through the angle steel models, design welding parameters, length difference and width difference, find the actual welding point coordinates of each batten plate, which helps workers to weld the actual batten plate with reference to the actual welding point coordinates when welding the batten plate. Or it is convenient for the automatic welding device to weld the actual batten plate according to the actual welding point coordinates.

[0107] Specifically, step S400 specifically includes:

[0108] S401. Retrieve the preset coordinate system, and the coordinate system is a two-dimensional coordinate system.

[0109] That is, the actual welding point coordinates output each time are the actual welding point coordinates of several actual gusset plates used to connect two actual angle steels, rather than the actual welding point coordinates of all actual gusset plates in the lattice column. Since in this embodiment, it is default that the actual specification parameters of the four actual angle steels are the same when calculating the actual welding point coordinates, only one set of actual welding point coordinates needs to be output.

[0110] S402. Starting from the origin of the coordinate system, with the actual length as the spacing, generate the actual length coordinate point b1 along the Y-axis direction; starting from the origin of the coordinate system, with the actual width as the spacing, generate the first actual width coordinate point a1 along the X-axis direction; generate the first actual plane model of the actual angle steel based on the origin, the actual length coordinate point b1, and the first actual width coordinate point a1.

[0111] For ease of understanding, refer to Figure 3 and Figure 4 , for example, in this embodiment, the actual length is 10 meters and the actual width is 1 meter, then the coordinate of point b1 is (0, 10), and the coordinate of a1 is (1, 0).

[0112] S403. Based on the adjacent angle steel spacing L1 and the actual width, obtain the second actual width coordinate point a2 and the third actual width coordinate point a3; generate the second actual plane model based on the actual length coordinate point b1, the second actual width coordinate point a2, and the third actual width coordinate point a3.

[0113] In this embodiment, the adjacent angle steel spacing L1 is 1.5 meters, then the coordinate of a2 is (2.5, 0), the coordinate of a3 is (3.5, 0), and the coordinate of b2 is (2.5, 10).

[0114] S404. Based on the number of gusset plates, obtain the number of adjacent design spacings; based on the adjacent design spacing L2 and the number of adjacent design spacings, obtain the total adjacent design spacing.

[0115] In this embodiment, the number of gusset plates is 4, then the number of adjacent design spacings is the number of gusset plates minus one, which is 3; the total adjacent design spacing is the adjacent design spacing L2 multiplied by the number of adjacent design spacings, that is, 3 * L2. In this embodiment, the adjacent design spacing L2 is 1 meter, and the total adjacent design spacing is 3 meters.

[0116] S405. Based on the adjacent design spacing L2, the head-end design spacing L3, and the tail-end design spacing L4, obtain the total length design spacing.

[0117] In this embodiment, the head-end design spacing L3 is 1 meter and the tail-end design spacing L4 is 1.5 meters, then the total length design spacing = L3 + L4 + L2 * 3 = 5.5 meters.

[0118] S406. Obtain the head-end design proportion based on the total designed spacing and the head-end designed spacing L3; obtain the tail-end design proportion based on the total designed spacing and the tail-end designed spacing L4; obtain the actual head-end spacing L31 based on the head-end design proportion, the length difference, and the head-end designed spacing.

[0119] In this embodiment, the length difference is 0.1 m. The head-end design proportion = L3 / total designed spacing, which is 1 / 5.5; the tail-end design proportion = L4 / total designed spacing, which is 1.5 / 5.5; the actual head-end spacing L31 = 1 / 5.5 * length difference + L3 = 1.018 m.

[0120] S407. Obtain the actual head-end ordinate based on the actual head-end spacing L31 and the actual length coordinate point b1, and obtain the first actual head-end abscissa based on the first designed margin L5 and the width difference; obtain the first actual head-end coordinate point n1 based on the actual head-end ordinate and the first actual head-end abscissa.

[0121] In this embodiment, the width difference is 0.1 m and the first designed margin L5 is 0.5 m. The actual head-end ordinate = the ordinate of the actual length coordinate point b1 - the actual head-end spacing L31 = 10 - 1.018 = 8.982; the first actual head-end abscissa = the first designed margin L5 + the width difference. That is, the coordinates of n1 are (0.6, 8.982) and L51 = 0.6.

[0122] S408. Obtain the second actual head-end coordinate point n2 based on the third actual width coordinate point a3, the second designed margin L6, the width difference, and the actual head-end ordinate.

[0123] Specifically, in this embodiment, the second designed margin L6 = 0.5, the second actual head-end abscissa = the abscissa of the third actual width coordinate point a3 - L61 = 3.5 - 0.5 - 0.1 = 2.9; L61 = the second designed margin L6 + the width difference = 0.5 + 0.1 = 0.6. It is not difficult to understand that the width difference is positive in this embodiment, indicating that the actual width is greater than the designed width; if the actual width is less than the designed width, the width difference is negative.

[0124] The coordinates of the second actual head-end coordinate point n2 are (2.9, 8.982).

[0125] S409. Obtain the actual tail-end spacing L41 based on the tail-end design proportion, the length difference, and the tail-end designed spacing.

[0129] S411. Obtain the second actual tail-end coordinate point n4 based on the third actual width coordinate point a3, the second design margin L6, the width difference, and the actual tail-end ordinate.

[0130] Specifically, in this embodiment, the coordinates of the second actual tail-end coordinate point n4 are (2.9, 1.527).

[0131] S411. Obtain the adjacent design proportion based on the adjacent design spacing L2 and the total length design spacing; obtain the actual adjacent spacing L21 based on the adjacent design proportion, the length difference, and the adjacent design spacing L2.

[0132] Adjacent design proportion = L2 / total length design spacing = 1 / 5.5; L21 = 1 / 5.5 * length difference + L2 = 1.018 meters.

[0133] S412. Obtain the batten width based on the actual adjacent spacing L21, the first actual tail-end coordinate point n3, the first actual head-end coordinate point n1, the number of adjacent design spacings, and the number of battens.

[0134] The batten width referred to in this embodiment is Figure 4 the length of the middle batten along the Y-axis. It is not difficult to understand that the batten length in this embodiment is Figure 4 the length of the middle batten along the X-axis. Batten width = [(ordinate of n1 - ordinate of n3) - (L21 * number of adjacent design spacings)] / number of battens = 1.1.

[0135] S413. Output the first side corner coordinate points of each batten based on the first actual tail-end coordinate point n3, the batten width, and the actual adjacent spacing L21.

[0136] In this embodiment, the first side corner coordinate points of each batten include n5, n6, n7, n8, n9, and n10. Taking n5 as an example, the abscissa of n5 is the same as the abscissa of the first actual tail-end coordinate point n3, both being 0.6; the ordinate of n5 = ordinate of n3 + batten width = 2.627. The ordinate of n6 = ordinate of n5 + L21 = 3.645, and so on.

[0137] S414. Output the second side corner coordinate points of each batten based on the second actual tail-end coordinate point n4, the batten width, and the actual adjacent spacing L21.

[0138] In this embodiment, the second-side corner coordinate points of each batten plate include n11, n12, n13, n14, n15, and n16. The abscissa of the second-side corner is the same as the abscissa of the second actual end coordinate point n4, and the calculation method of the ordinate is the same as that of the first-side corner coordinate point, so it will not be elaborated here.

[0139] The implementation principle of the batten plate welding point calculation method for the foundation pit battened four-limb lattice column in the embodiment of the present application is as follows: After obtaining the design specification parameters and actual specification parameters, the length difference and width difference are obtained, and then the actual welding point coordinates are obtained based on the length difference, width difference, and design welding parameters. Since a preset coordinate system is used, during the welding process of the batten plate by workers, a coordinate system can be equivalently obtained, and the output actual welding point coordinates are marked on the actual angle steel, which helps to improve the accuracy of the welding position of the batten plate.

[0140] This embodiment also discloses a batten plate welding point calculation system for a foundation pit battened four-limb lattice column. Refer to Figure 5 , including a first acquisition module 1 for acquiring the design specification parameters of the design angle steel and the design welding parameters of the design batten plate in the lattice column drawing; a second acquisition module 2 for acquiring the actual specification parameters of the actual angle steel. The first acquisition module can be drawing recognition software or a recognition program; the second acquisition module can be software or a program connected to a measuring instrument such as a 3D laser scanner for acquiring the measurement data transmitted by the measuring instrument. A calculation module 3 for obtaining the length difference and width difference between the design angle steel and the actual angle steel based on the design specification parameters of the design angle steel and the actual specification parameters of the actual angle steel. A coordinate generation module 4 for outputting the actual welding point coordinates of the actual batten plate based on the design welding parameters, length difference, and width difference, in combination with a preset coordinate system.

[0141] After outputting the actual welding point coordinates of the actual batten plate, workers can mark the coordinate points on the angle steel manually or by equipment according to the actual welding point coordinates, which helps the welding workers to weld the batten plate with the coordinate points on the angle steel as reference points during the welding of the batten plate, improving the accuracy of the welding position of the batten plate, and thus helping to improve the quality of the lattice column.

[0142] This embodiment also discloses a batten plate welding point calculation terminal for a foundation pit battened four-limb lattice column, including a memory and a processor, and a computer program capable of being loaded and executed by the processor for the batten plate welding point calculation method of the foundation pit battened four-limb lattice column is stored in the memory.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
