Detailed Description

The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Because the number of the local variable cross sections to be determined in the service drawing of the actual hollow floor is very large, and the local variable cross sections in most of the service drawing are not marked with specific sizes, a user is required to measure the local variable cross section sizes of each main rib beam span from the target drawing, and then the user manually inputs specific numerical values into modeling software, so that the user operation is very complicated, and the modeling efficiency is very low.

Since the length of the partially variable cross-section wide portion of the main rib beam span in the target drawing based on the hollow floor is always aligned with the secondary rib beam, the width of the wide portion is always aligned with the hole forming core mold, wherein the secondary rib beam is in turn related to the number of hole forming core mold gaps where the wide portion extends out of the main rib beam span. Therefore, based on the two characteristics, the parameter information of the local variable cross section can be automatically calculated according to the pore-forming core mould around the main rib beam and the secondary rib beam. In the invention, the secondary rib beams can be abstracted into the number of gaps between the pore-forming core dies, so that even if a specific model of the secondary rib beam is not drawn in a target drawing, the parameters of the local variable cross section can be calculated through the pore-forming core dies and the gaps between the pore-forming core dies, and the local variable cross section model of the target beam span is generated.

In accordance with an embodiment of the present invention, there is provided an embodiment of a method of locally varying cross-section of a target beam span, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and that, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown herein.

According to the construction method of the main rib girder span local variable cross section model, the target girder span is determined, and the local variable cross section parameters corresponding to the target girder span are determined according to the determined target girder span, so that the determination efficiency of the local variable cross section parameters is improved, and meanwhile, the error rate of manual measurement or manual input is avoided; and determining the local variable cross section model of the target beam span based on the local variable cross section parameters of the target beam span so as to determine all the main rib beam span local variable cross section models in the target drawing, thereby avoiding the complex and complicated construction flow of the local variable cross section model and improving the construction efficiency of the local variable cross section model.

In this embodiment, a method for determining a parameter of a target beam span local variable cross section is provided, which may be used in an electronic device, such as a computer, a mobile phone, a tablet computer, etc., fig. 2 is a flowchart of a method for determining a parameter of a main rib beam span local variable cross section according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:

S21, determining a target beam span. For details, see the above description of step S11, and will not be repeated here.

Specifically, the step S22 may include the steps of:

s221, identifying a target pore-forming core mold with the distance between the target pore-forming core mold and the target beam span within a preset range.

The target pore-forming core mould is a light filling body which is internally arranged or exposed in the hollow floor slab and is permanently embedded in the hollow floor slab. The target pore-forming core mould and the main rib beam are arranged in parallel, the preset range is the distance between the target beam span and the pore-forming core mould, and specific numerical values of the target pore-forming core mould and the main rib beam span can be correspondingly arranged according to actual conditions. In the target drawing, a plurality of pore-forming core dies are arranged around the main rib beam, the electronic equipment can calculate the distance between each pore-forming core die and the target beam span, and the pore-forming core dies with the distance between the pore-forming core dies and the target beam span within a preset range are determined as target pore-forming core dies. Specifically, the target pore-forming core mold is not limited to one pore-forming core mold, and may be a set of a plurality of pore-forming core molds.

S222, determining initial parameters of the target beam crossing local variable cross section. The initial parameters are used to determine the relationship of the target pore-forming mandrel to the local variable cross-section.

After the target beam span is determined, initial parameters corresponding to the local variable cross section of the target beam span are determined according to the target beam span. The initial parameters are used for determining the relation between the target pore-forming core mould and the local variable cross section. The relationship may include a dimensional relationship of the local variable cross section, a positional relationship of the target pore-forming core mold and the local variable cross section, and the like.

Specifically, as shown in fig. 3, the initial parameters include a target beam width setting across the partial variable cross section and a target beam width setting across the partial variable cross section. The initial parameters may be obtained through an input operation of a user, for example, the setting format of the length of the wider portion may be: an integer (unit mm) between [0,50000 ]; the method can also be as follows: * N, N is an integer between [1,50], e.g., 3, indicating that the wide projection extends over 3 hole forming mandrels and 1 secondary rib beam width (hole forming mandrel gap); the number of pore-forming core moulds which the wide outlet part extends through is N, and the number of secondary rib beams is always 1. The setting format of the width of the wide portion may be: an integer (unit mm) between [0,5000 ]; s may also be used to represent the distance from the primary rib to the pore-forming mandrel.

If the user can determine the length of the widened portion or the width of the widened portion of the target beam across the partial variable cross section, the integer (unit mm) between [0,50000] or the integer (unit mm) between [0,5000] can be directly input; if the user is not sure that the target beam spans the widened portion length or the widened portion width of the local variable cross section, then N and S may be entered.

S223, determining the parameters of the local variable cross section of the target beam span according to the target pore-forming core mould and the initial parameters.

Parameters of the local variable cross section of the target beam span include the width of the widened portion and the width of the widened portion. According to the initial parameters, the relation between the target pore-forming core mould and the local variable cross section can be determined, the position of the target pore-forming core mould with the distance from the target beam span within the preset range is combined, the parameters of the local variable cross section are automatically calculated according to the target pore-forming core mould and the secondary rib beam with the distance from the main rib beam span within the preset range based on the two characteristics that the length of the wide part of the local variable cross section of the main rib beam span is always aligned with the secondary rib beam and the width of the wide part is always aligned with the pore-forming core mould. The secondary rib beams can be abstracted into gaps among the pore-forming core dies, and the secondary rib beams can be not drawn in a target drawing, so that parameters of a local variable cross section can be automatically calculated according to the positions of the target pore-forming core dies and the positions of the gaps of the target pore-forming core dies.

Specifically, the step S221 may include the steps of:

(1) And identifying the positions of each main rib beam and the pore-forming core mould in the target drawing.

The main rib beam is a frame beam of a connecting column in the hollow floor slab, and the local variable cross-section designs are different in different hollow floor slab structures. A plurality of hole-forming mandrels are provided around each of the primary ribs, and the positions of the hole-forming mandrels distributed around each of the primary ribs can be determined by identifying each of the primary ribs in the target drawing.

(2) And determining all the closed areas surrounded by the main rib beams by utilizing the position relation of the main rib beams.

The closed area is a closed space range area surrounded by the main rib beams. The position relation among the main rib beams can be obtained by identifying all the main rib beams in the target drawing, and all the closed areas surrounded by the main rib beams can be obtained by utilizing the position relation among the main rib beams based on the position intersection among the main rib beams contained in the target drawing.

(3) And determining a target closed area corresponding to the target beam span based on the closed area and the target main rib beam corresponding to the target beam span.

The target main rib beam is a main rib beam corresponding to the erection target beam span. The closed areas formed by the main rib beams can comprise a plurality of closed areas, and the methods for calculating the local variable cross-section parameters in the closed areas are consistent, so that one closed area can be selected as a target closed area for calculating the local variable cross-section parameters. Specifically, the target closed area may be selected according to the target beam span, and the closed area to which the target beam span belongs is taken as the target closed area.

(4) And determining the target pore-forming core mould by utilizing the position relation between the pore-forming core mould and the target closed area in the target drawing.

The closed area formed by the main rib beam comprises a plurality of pore-forming core dies, the pore-forming core dies or pore-forming core die sets corresponding to the range of the target closed area can be determined according to the position of the target closed area, and the pore-forming core dies or pore-forming core die sets corresponding to the range of the target closed area are used as target pore-forming core dies.

Specifically, the step (2) includes the steps of:

(21) The center lines of all the main rib beams are obtained.

(22) And determining the central lines of the main rib beams with the association relationship by utilizing the position relationship among the central lines of the main rib beams, so as to obtain an association central line set.

(23) And traversing the associated center line set by taking the center lines in the associated center line set as reference lines in sequence, and determining all the closed areas surrounded by the main rib beams.

Illustratively, the central lines of all the main rib beams are obtained, an edge model is constructed according to the obtained central lines of the main rib beams, the position relation among the central lines in the edge model is judged, the central lines with the association relation are determined, the central lines with the association relation form an association central line set, the association central lines can be an edge linked list data structure, and if the central lines with the association relation are added into the edge linked list data structure. Traversing the edge linked list data structure by taking the central lines in the associated central line set as reference lines, and if the edge linked list data structure is traversed to the annular structure, considering that all the traversed central lines form a closed area; and replacing the other central line as a datum line, continuing to traverse in the edge linked list data structure, skipping over the central line where the closed area is found, until all central lines in the edge linked list data structure are traversed as the datum line, and ending the traversing, thereby determining all the closed areas surrounded by the main rib beams.

And determining all the closed areas surrounded by the main rib beams by identifying the positions of the main rib beams and the pore-forming core mould in the target drawing and determining the target closed areas corresponding to the target beam span based on the closed areas and the target beam span corresponding to the target main rib beams by utilizing the position relation of the main rib beams, and determining the target pore-forming core mould by utilizing the position relation of the pore-forming core mould and the target closed areas in the target drawing. The target pore-forming core mould in the range of the target beam span is automatically identified through the constructed closed area, and the obtained target pore-forming core mould is utilized to determine the local variable cross-section parameters of the target beam span, so that the purpose of directly and quickly setting the local variable cross-section for the target beam span is realized, and the determination efficiency of the local variable cross-section parameters is improved.

In particular, the parameters of the local variable cross section include the length of the widened portion. The length of the wide-out portion represents the number of the hole-forming core dies through which the wide-out portion of the partially variable cross-section extends and the number of the hole-forming core die gaps through which the wide-out portion extends. Wherein the void of the core mold is the void of the adjacent target core mold as shown in fig. 4. The step S223 may include the steps of:

(1) And determining the gap between adjacent target pore-forming mandrels along the extending direction of the target beam span.

The gap of the target pore-forming core mould is the distance between two adjacent columns of pore-forming core moulds. The electronic device can identify the positions of the target pore-forming core mould and the target pore-forming core mould along the extending direction of the target beam span in the target drawing, and the distance between the adjacent pore-forming core moulds, namely the gap between the adjacent target pore-forming core moulds, is determined through the positions of the adjacent pore-forming core moulds.

(2) The length of the widened portion is determined based on the initial parameters, the gap between adjacent target void-forming mandrels, and the length of the corresponding target void-forming mandrel, with the end point of the target beam span as a starting point.

The length of the target void-forming core die is the dimension of the target void-forming core die in the direction of elongation along the target beam span. And sequentially arranging the target pore-forming core dies in the target closed area from left to right along the extending direction of the target beam span to obtain the gaps of the adjacent target pore-forming core dies in the arranged target closed area. The index position of the arranged target pore-forming core mould can be determined based on the initial parameters, the end point of the determined target beam span is taken as a starting point, and the length of the widened part of the local variable cross section can be determined based on the initial parameters of the initial setting, the gaps between the adjacent target pore-forming core moulds and the length of the corresponding target pore-forming core mould.

Specifically, the number N of pore-forming core dies with extended wide-out lengths is determined in the initially set local variable cross-section parameters, so that N-1 gaps can be determined among the N pore-forming core dies, and the electronic equipment can calculate the length of the wide-out portion of the local variable cross-section by utilizing the lengths of the N target pore-forming core dies and the N-1 gaps.

Optionally, the target void-forming core mold comprises a first target void-forming core mold and a second target void-forming core mold located on opposite sides of the target beam span. The above (2) may include the steps of:

(21) And determining the first length of the widened portion by using the initial parameters, the gaps between adjacent first target hole-forming mandrels and the lengths of the corresponding first target hole-forming mandrels with the end points of the target beam spans as starting points. The first length of the wider portion may be referred to in the above description, and will not be described herein.

(22) And determining the second length of the widened portion by using the initial parameters, the gap between adjacent second target void-forming mandrels, and the length of the corresponding second target void-forming mandrel. The second length of the wider portion may be referred to in the above description, and will not be described herein.

(23) The minimum value of the first length of the wide portion and the second length of the wide portion is determined as the length of the wide portion.

Taking the target beam span horizontal device as an example, the first target pore-forming core mold is a pore-forming core mold in the closed area of the target Liang Kuashang side (the target beam span direction rotates 90 degrees anticlockwise), and the second target pore-forming core mold is a pore-forming core mold in the closed area below the target beam span (the target beam span direction rotates 90 degrees clockwise). The first length can be obtained by utilizing the local variable cross-section initial parameters of the upper part of the target beam span, the gap between the adjacent first target pore-forming core dies and the length of the corresponding first target pore-forming core dies; the second length may be derived using the local variable cross-section initial parameters of the target beam span below, the gap between adjacent second target void-forming mandrels, and the length of the corresponding second target void-forming mandrel.
