Before describing the embodiments of the present invention, the related terms related to the embodiments of the present invention are first explained as follows:

the laminated slab can be an assembled concrete member formed by laminating a bottom plate and a truss arranged on the bottom plate after a concrete layer is poured, has good integrity, and the upper surface and the lower surface of the bottom plate are smooth, so that decoration of a finish coat is facilitated, and the laminated slab is suitable for high-rise buildings and large-bay buildings with high integral rigidity requirements. The buildings are divided into different purposes, and the buildings can be residential buildings, commercial buildings and the like, and are not described in detail here.

The truss may include an upper chord rib, a lower chord rib, and a web rib connecting the upper chord rib and the lower chord rib. The web bar rib may be of a wave structure so that web peaks and web valleys are present on the web bar rib. For convenience of the subsequent description, the web member peaks may be defined as truss peaks, and the web member valleys may be defined as truss valleys.

When the distribution mode of the lifting points of the truss is determined, the positions of the lifting points can be determined based on the wave crests of the truss. And under the condition that the trusses need to be cut off when encountering the cave opening, determining that the regenerated trusses positioned on two sides of the cave opening are truss peaks or truss troughs at the end adjacent to the cave opening so as to determine the position of the hoisting point based on the regenerated truss peaks.

In the related art, in order to facilitate the hoisting of the laminated slab, the hoisting point position of the laminated slab needs to be determined frequently, so that the hoisting can be completed directly according to the hoisting point position during the field installation construction of the laminated slab, and the installation efficiency of the laminated slab is improved. However, in the prior art, the arrangement of the hoisting point positions needs manual calculation, the time consumption is long, and the automatic arrangement cannot be realized.

Aiming at the laminated slab with complex geometric shapes and considering a plurality of holes and openings with gaps and the like, a large amount of time is needed for manually calculating the positions of lifting points, the dynamic adjustment of the positions of the lifting points in the hole area cannot be realized, the actual production requirement cannot be met, and the arrangement efficiency of the lifting points is low.

In view of the above problems, exemplary embodiments of the present invention may determine the distribution of hanging points of the truss on the composite slab by using one or more types of design software modeling before the composite slab is manufactured.

Based on this, the exemplary embodiment of the present invention provides a method for determining a hanging point distribution manner, which may be used to determine a hanging point distribution manner of a composite slab, so as to solve technical problems in the prior art that the arrangement of hanging point positions requires manual calculation, the time consumption is long, and the automatic arrangement cannot be implemented. Meanwhile, in the case of a laminated slab with a complex geometric contour and multiple holes, the position of a hanging point in a hole area can be dynamically adjusted, the actual production requirement is met, and the arrangement efficiency of the hanging point is improved.

The suspension point distribution method of the exemplary embodiment of the present invention may be executed by an electronic device installed with one or more types of modeling software, which may be stored in a computer-readable storage medium, where the modeling software includes, but is not limited to: UG, CAD, BIM (Building Information Modeling, abbreviated as BIM), SPCS, PKPM-PC, revit, navisvarks, bentley Navigator, tekla Structures, archicades, and the like. The electronic device may include, but is not limited to, a desktop computer, a notebook computer, a tablet computer, and the like.

The hoisting point distribution mode determining method of the exemplary embodiment of the invention is used for determining the hoisting point distribution mode of the laminated slab, and the laminated slab at least comprises the following steps: the device comprises a bottom plate and at least one truss arranged on the bottom plate. It should be understood that if the number of trusses is plural, the extending direction of the plural trusses on the base plate may be the same.

Fig. 1 is a flowchart illustrating a method for determining a suspension point distribution manner according to an exemplary embodiment of the present invention. As shown in fig. 1, the method for determining the distribution mode of suspension points according to the exemplary embodiment of the present invention includes:

step 101: and obtaining modeling information of the laminated slab, wherein the modeling information of the laminated slab at least comprises modeling data of at least one truss, and the modeling data of the truss at least comprises truss position information.

In practical application, when the hanging point distribution mode of the laminated slab is determined, the modeling information of the laminated slab needs to be acquired. In view of the technical problem to be solved by the exemplary embodiments of the present invention, the modeling information of the superimposed sheet may include at least modeling data of at least one truss. The modeling data of the truss includes at least truss position information.

The position information of the girder of the exemplary embodiment of the present invention may be a set of coordinates of all points located on the girder. In practical applications, the position of the truss on the bottom plate, the truss length, the truss width, the truss peak position, the truss valley position, the truss peak spacing, etc. may be determined based on the set of coordinates of all points on the truss, but are not limited thereto.

Step 102: a plurality of candidate hoist point locations and two first theoretical hoist point regions are determined based on the truss position information. The distribution mode of hoisting points can satisfy the symmetrical atress of superimposed sheet in hoist and mount in order to guarantee to hoist the stability of superimposed sheet in hoist and mount process, prevent the condition that the superimposed sheet turned on one's side, avoid taking place the incident, consequently, when setting up the distribution mode of hoisting points, need carry out rational design to the hoisting point position.

Each candidate hoisting point position determined by the exemplary embodiment of the present invention based on the position information of the girder may be an actually set position of the target hoisting point on the girder. The location of these candidate suspension point locations on the truss may be determined based on the structure of the truss.

Illustratively, each candidate hoist point location may be located at a truss peak location. At the moment, the candidate hoisting point is located at the contact position of the web member rib and the upper chord rib, and the candidate hoisting point has higher strength, so that when the lifting hook is hung at the position, a better acting foundation is provided, and therefore when the candidate hoisting point is located at the peak position of the truss, the effective hoisting of the laminated slab by the lifting hook can be ensured, and the possibility of deformation of the truss can be reduced.

In one example, a plurality of candidate suspension point positions located on the same truss may be distributed along the length direction of the truss, and the distance between two adjacent candidate suspension point positions may be equal to K times the peak distance of the truss, where K is an integer greater than or equal to 1.

Figure 2 illustrates a schematic diagram of a candidate suspension point distribution in accordance with an exemplary embodiment of the present invention. Wherein, the first and the second end of the pipe are connected with each other,Qrepresenting the truss peak position and the white circles represent candidate hoist point positions. As shown in fig. 2, the truss 200 has 9 truss peak positions, and when K =1, the spacing between two adjacent candidate suspension point positions may be equal to the truss peak spacing. At this time, each truss wave on the same trussThe peak positions are the candidate hoisting point positions 201, so that the density of the candidate hoisting point positions on the same truss is higher, the possibility of selecting the target hoisting point position in a missing or wrong way can be avoided when the target hoisting point position is selected subsequently, and the hoisting stability is improved.

When K is larger than or equal to 2, the distance between two adjacent candidate hoisting point positions can be larger than or equal to 2 times the distance between the wave crests of the truss. At the moment, the density of the candidate hoisting point positions on the same truss is determined by the size of K, so that the size of K can be controlled, and the density of the candidate hoisting point positions can be adjusted, thereby reducing the calculation complexity of subsequent target hoisting point position determination and improving the target hoisting point distribution mode determination efficiency.

FIG. 3 illustrates another candidate suspension point distribution diagram in accordance with an exemplary embodiment of the present invention. Wherein the content of the first and second substances,Qrepresenting the truss peak position and the white circles representing candidate suspension point positions. As shown in fig. 3, the truss 200 has 9 truss peak positions, and when K =2, the spacing between two adjacent candidate suspension point positions may be equal to 2 times the truss peak spacing. At this time, a candidate suspension point position 201 appears on every other truss peak on the same truss, so that the density of the candidate suspension point positions on the same truss is lower than that shown in fig. 2.

The two first theoretical hoisting point areas determined based on the truss position information according to the exemplary embodiment of the present invention may be location areas of the target hoisting point on the truss determined in a determination manner commonly used in the industry. When the laminated slab is hoisted based on the target hoisting points selected by the two first theoretical hoisting point areas, the laminated slab can be stressed symmetrically in the hoisting process, so that the stability of the laminated slab in the hoisting process is ensured, the condition that the laminated slab turns on one side is prevented, and safety accidents are avoided.

For example, the two first theoretical suspension point regions may include a first side theoretical suspension point region and a second side theoretical suspension point region. The theoretical suspension points defined by the first side theoretical suspension point region may be proximate to the first end of the truss and the theoretical suspension points defined by the second side theoretical suspension point region may be proximate to the second end of the truss. It should be understood that the first end of the truss and the second end of the truss may be two ends distributed along the length of the truss. At the moment, the two first theoretical hoisting point areas can be bilaterally symmetrical about the middle point of the truss, so that the stability of the laminated slab in the hoisting process is ensured, and the condition that the laminated slab turns on one side to cause accidents is prevented.

Step 103: and determining the distribution mode of at least two target hoisting points of the same truss from the positions of the plurality of candidate hoisting points based on the two first theoretical hoisting point areas.

When the number of the target hoisting points is two, the distribution mode of the two target hoisting points can be determined directly according to the relative position relation between the candidate hoisting point position and the first theoretical hoisting point area. When the number of the target hoisting points is more than two, the distribution mode of the two target hoisting points is determined according to the relative position relationship between the candidate hoisting point position and the first theoretical hoisting point area, and at least one target hoisting point between the two target hoisting points is determined according to the determined distribution mode of the two target hoisting points and the candidate hoisting point position.

As can be seen from the above, in the method for determining distribution patterns of suspension points provided in the exemplary embodiment of the present invention, a plurality of candidate suspension point positions and two first theoretical suspension point regions may be determined based on the truss position information, the distribution patterns of at least two target suspension points of the same truss may be determined from the plurality of candidate suspension point positions based on the two first theoretical suspension point regions, and the suspension points may be automatically arranged by using the distribution patterns of suspension points obtained through automatic calculation, so as to meet the requirements for hoisting laminated slabs. Therefore, when the laminated slab is installed on site, the hoisting positions can be conveniently and quickly found based on the hoisting point distribution mode of automatic calculation, so that the hoisting point arrangement efficiency of the laminated slab is improved, and the technical problems that the arrangement of the hoisting point positions in the prior art needs manual calculation, is long in time consumption and cannot automatically arrange the hoisting points are solved.

In an alternative, FIG. 4 illustrates a flow chart for determining candidate suspension point locations and a first theoretical suspension point region in accordance with an exemplary embodiment of the present invention. As shown in fig. 4, determining a plurality of candidate hoisting point positions and two first theoretical hoisting point areas based on the truss position information includes:

step 401: and determining peak positioning data of the truss based on the truss position information. The peak location data may include: a truss length, a truss peak spacing, and at least one truss peak position.

In practical applications, peak location data of the truss may be determined based on a set of coordinates of all points on the truss, and the peak location data may include: a truss length, a truss peak spacing, and at least one truss peak position, which may be a coordinate of a truss peak.

Step 402: a plurality of candidate hoist point positions are determined based on the peak position data. When the crest positioning data include: the number of truss peaks included in the truss may be determined based on the truss length and the truss peak spacing when the truss length, the truss peak spacing, and the at least one truss peak position are determined, and then the other truss peak positions included in the truss may be determined based on the truss peak position and the truss peak spacing after the at least one truss peak position is determined.

Fig. 5 shows a schematic diagram of peak location data of a truss in accordance with an exemplary embodiment of the invention. As shown in fig. 5, the truss length may be determined based on coordinates of a first end point a and a second end point b along the length of the truss 200LDetermining the truss peak spacing based on the coordinates of two adjacent truss peaks 202 (or truss valleys 203) on the truss 200dBased on the length of the trussLAnd the distance between the wave crests of the trussdDetermining the number of the wave crests of the truss contained in the truss asm，mMeans greater than 0 and less than or equal toL/dIs an integer of (1). After determining at least one truss peak position, the determination may be based on the truss peak position and the truss peak spacingdAnd determining the positions of peaks of other trusses contained in the truss. Suppose that it is knownrThe peak position of each truss isQ _r Then it is firstxPosition of wave peak of trussQ _x Satisfies the following conditions:Q _x =Q _r +d (x-r)。

for example, as shown in fig. 5, the truss 200 has a total of 9 truss peaks, and the 9 truss peaks are sequentially defined from left to right as a 1 st truss peak, a 2 nd truss peak, \8230;, an 8 th truss peak, and a 9 th truss peak. Known No. 3 truss wave crestIn the position ofQ ₃ Then based onQ _x The position of the wave crest of the 1 st truss can be determined by the satisfied formulaQ ₁ =Q ₃ -2dPosition of wave crest of No. 2 trussQ ₂ =Q ₃ -dPosition of peak of truss 4Q ₄ =Q ₃ +dPosition of wave crest of No. 5 trussQ ₅ =Q ₃ +2dPosition of peak of No. 6 trussQ ₆ =Q ₃ +3dPosition of peak of No. 7 trussQ ₇ =Q ₃ +4dPosition of the 8 th truss wave crestQ ₈ =Q ₃ +5dPosition of the 9 th truss peakQ ₉ =Q ₃ +6d。

On the basis, the position of each truss peak can be used as a candidate lifting point position, and the position of the truss peak on the truss can be designated as the candidate lifting point position according to a certain rule.

In one example, as shown in fig. 2, when each truss peak position is a candidate suspension point position, the 9 truss peak positions shown in fig. 2 are candidate suspension point positions 201. In this case, the number of candidate suspension point positions is 9 in total.

In another example, as shown in fig. 3, the 2 nd, 4 th, 6 th and 8 th truss peaks may be defined as candidate suspension point locations 201 from left to right. At this time, the number of candidate suspension point positions is 4 in total.

Step 403: two first theoretical suspension point areas are determined based on the peak location data and the position adjustment parameters. The optimal lifting point position exists in each first theoretical lifting point area, and the position adjusting parameters can be used for adjusting the position of each first theoretical lifting point area on the truss. When the first theoretical lifting point area is close to the end part of the truss, the degree of the first theoretical lifting point area close to the end part of the truss can be adjusted by utilizing the position adjusting parameters, so that the target lifting point position determined based on the first theoretical lifting point area is proper, and the lifting is convenient.

Each first theoretical craneThe point area may be determined according to an empirical formula, for example: according to the position adjusting parameters, the distance between the two optimal lifting point positions and the end part of the corresponding truss is determinedL/X（LWith reference to the foregoing), and then setting the length of the first theoretical lifting point area using each of the optimal lifting point positions as the center position of the corresponding first theoretical lifting point area. Based on this, each first theoretical hoisting point region satisfies:

，P ₀ the length of the first theoretical lifting point area is shown, the length direction is the extending direction of the truss,Lthe length of the truss is shown as,dthe spacing between the peaks of the truss is shown,kthe error coefficient is represented by a coefficient of error,Xthe position adjusting parameter can be self-defined by a user according to actual needs, can be an empirical value or a test value obtained through a plurality of tests,Xis an integer greater than or equal to 1. For example:Xis an integer of 1 or more and 10 or less.kCan be greater than or equal to 0 and less than or equal todThe value of/2.

In order to make the candidate suspension point position within the first theoretical suspension point region as much as possible, the length of the first theoretical suspension point region centered on the optimal suspension point position may be controlled based on the truss peak pitch. At the same time, using error coefficientskAnd adjusting the length of the first theoretical lifting point area, thereby further ensuring that the candidate lifting point position falls into the first theoretical lifting point area, and further providing a selection basis for screening the target lifting point position.

In practical application, if the number of the target hoisting points is equal to two, the candidate hoisting point position closest to the optimal hoisting point position in each first theoretical area is determined as the first target hoisting point position. The distribution of the two target suspension points on the truss may be formed based on the two first target suspension point positions determined from within the two first theoretical suspension point areas.

In one example, a number of candidate suspension point locations present within a first theoretical suspension point region may be determined. And if the candidate lifting point position exists in the first theoretical lifting point area, determining the candidate lifting point position as the first target lifting point position. If it is determined that at least two candidate hoisting point positions exist in the first theoretical hoisting point area, a first target hoisting point position can be selected from the at least two candidate hoisting point positions, and the first target hoisting point position is the candidate hoisting point position which is closest to the optimal hoisting point position in the at least two candidate hoisting point positions.

FIG. 6 illustrates a schematic diagram of a determination of a first target suspension point location in accordance with an exemplary embodiment of the present invention. As shown in fig. 6, it can be determined based on the formula satisfied by each first theoretical lifting point regionXIf =4, the two first theoretical hoisting point areas shown by the truss 200 are determined. At this time, the optimum hanging point positionPAt a distance from the ends of the truss 200L/4. As can be seen from FIG. 6, there is one candidate suspension point location for each first theoretical suspension point region, and the best suspension point locationPAnd the candidate hoisting point position can be used as the first target hoisting point position.

Figure 7 illustrates another schematic diagram for determining a location of a first target suspension point in accordance with an exemplary embodiment of the present invention. If the first theoretical lifting point region is as shown in FIG. 7P ₀ At least two candidate suspension point positions existQ ₀₁ AndQ ₀₂ from at least two candidate suspension point positionsQ ₀₁ AndQ ₀₂ selects a candidate hoisting point position as a first target hoisting point positionP ₁ . If the position of the candidate hanging pointQ ₀₁ And the optimum hanging point positionPIs a distance ofd ₁ Candidate hanging point positionQ ₀₂ And the optimum hanging point positionPIs a distance ofd ₂ And Δd ₁ Less than Δd ₂ Then the candidate hanging point position is determinedQ ₀₁ As a first target hanger point positionP ₁ 。

In practical application, if the number of the target hoisting points is greater than two, after the two first target hoisting point positions are determined, other target hoisting point positions than the two first target hoisting point positions need to be determined. In other words, in case that it is determined that the number of the target lifting points is greater than two, a second target lifting point position located between two first target lifting point positions is determined based on the number of the target lifting points and the two first target lifting point positions. At this time, the distribution mode of the target hoisting points on the truss can be determined by the two first target hoisting point positions and the at least one second target hoisting point position.

When determining a second target suspension point position located between two first target suspension point positions, at least one second theoretical suspension point position may be determined based on the number of target suspension points and the two first target suspension point positions, and then, from at least one candidate suspension point position located between the two first target suspension point positions, a candidate suspension point position adjacent to each second theoretical suspension point position is selected as the second target suspension point position.

For example, in the case that the number of the target suspension points on the truss is determined to be greater than 2, the second number of the target suspension points may be determined based on the number of the target suspension points and the number of the first target suspension points, and then the theoretical position of the second target suspension point located between the two first target suspension points may be determined based on the two first target suspension point positions. Thus, at least one second theoretical suspension point position may be determined based on the number of target suspension points and two first target suspension point positions, each second theoretical suspension point position satisfying:

wherein, in the process,igreater than 0 and less than or equal ton-an integer of 2, and (ii) a further integer,nthe number of the target hoisting points is shown,P ₁₁ andP ₁₂ two first target hanger point positions are indicated,P _i2 representing the second theoretical lifting point position.

In one example, if the second theoretical hoisting point position coincides with the candidate hoisting point position, the second target hoisting point position is the candidate hoisting point position coinciding with the second theoretical hoisting point position.

Fig. 8 shows a schematic diagram of a distribution of target suspension points according to an exemplary embodiment of the present invention. As shown in FIG. 8, the truss is considered as a straight line, and two black circles on the straight line represent two first target suspension points which have been determinedP ₁₁ AndP ₁₂ and 5 white circles represent candidate suspension point positions between two first target suspension point positions. If the number of the target lifting points is 3, the number of the second target lifting points can be determined to be 1, so that the position of the second theoretical lifting pointP ₂₁ Can satisfy the following conditions:

。

as can be seen in FIG. 8, the second theoretical point of suspension positionP ₂₁ And the position of the suspension point candidate represented by the third white circle from left to right, so that the position of the suspension point candidate represented by the third white circle can be determined as the second target suspension point position.

In another example, if the second theoretical suspension point position is offset from the candidate suspension point position, the second target suspension point position is: the candidate hoisting point position adjacent to the second theoretical hoisting point position is positioned between the first target hoisting point position and the second theoretical hoisting point position; the distance between the candidate hoisting point position adjacent to the second theoretical hoisting point position and the second theoretical hoisting point position is more than 0 and less thandWherein, in the step (A),drepresenting the truss peak spacing. At the moment, the crane can stably hoist the laminated slab in the process of hoisting the laminated slab in a labor-saving manner, so that the condition that the laminated slab turns on one side is prevented. It should be understood that the candidate suspension point positions adjacent to the second theoretical suspension point position may mean that the candidate suspension point positions fall into +/-with the second theoretical suspension point position as the centerdA candidate suspension point location within the range of (a).

Fig. 9 is a schematic diagram illustrating another distribution of target suspension points according to an exemplary embodiment of the present invention. As shown in FIG. 9, the truss is considered as a straight line, and the larger two black circles on the straight line represent the two first target suspension points that have been determinedP ₁₁ AndP ₁₂ two first target hoisting point positionsP ₁₁ AndP ₁₂ in an intermediate position ofOThe smaller two black circles represent the two second theoretical suspension point positions that have been determinedP ₂₁ AndP ₂₂ and 7 white circles represent candidate suspension point positions between two first target suspension point positions. If the number of the target hoisting points is 4, the number of the second target hoisting points can be determined to be 2, so that the position of the second theoretical hoisting pointP ₂₁ AndP ₂₂ can respectively satisfy:

and

。

as can be seen in FIG. 9, the second theoretical ceiling locationP ₂₁ AndP ₂₂ are offset from the candidate suspension point locations. For the second theoretical hoisting point positionP ₂₁ From the second theoretical hoisting point positionP ₂₁ The neighboring candidate positions are: candidate hanging point positions represented by a second white circle and a third white circle from left to right, wherein the second white circle is farther from the middle position than the third white circleOThus, a candidate suspension point location represented by a second white circle may be determined to be adjacent to a second theoretical suspension point locationP ₂₁ Second target hoisting point positionM ₁ . At this time, the second target hoisting point positionM ₁ At the first target hoisting point positionP ₁₁ And second theoretical hoisting point positionP ₂₁ In the meantime.

For the second theoretical hoisting point positionP ₂₂ From the second theoretical hoisting point positionP ₂₂ The neighboring candidate positions are: candidate hanging point positions represented by a fifth white circle and a sixth white circle from left to right, wherein the sixth white circle is farther from the middle position than the fifth white circleOThus, the candidate suspension point location represented by the sixth white circle may be determined to be adjacent to the second theoretical suspension point locationP ₂₂ Second target hoisting point positionM ₂ . At this time, the second target suspension point positionM ₂ At the first target hoisting pointP ₁₂ And second theoretical hoisting point positionP ₂₂ In the meantime.

In an alternative mode, if the bottom plate of the laminated slab has a structure such as a hole, a notch and the like, the truss needs to be cut off in the process of generating the truss.

For example: in the case where the truss has a chamfer, if a portion of the truss is located within the range of the chamfer, the portion of the truss located within the range of the chamfer should be removed. If the truss has the opening area, the truss structure in the opening area needs to be removed in the manufacturing process of the laminated slab, so that when the distribution mode of the hanging points is determined, the hanging points in the opening area need to be subjected to position adjustment, the distribution mode of the adjusted hanging points can ensure that the truss does not deform at the hanging point, meanwhile, the stability of the laminated slab in the hoisting process is ensured, the rollover of the laminated slab is prevented, and safety accidents are avoided.

In one example, the bottom plate has an opening, the modeling information of the composite slab further includes opening modeling data, and after the modeling information of the composite slab is obtained, before determining a plurality of candidate hoisting point positions and two first theoretical hoisting point areas based on the truss position information, the method of the exemplary embodiment of the present invention further includes:

and under the condition that the truss and the hole area defined by the hole modeling data are overlapped, removing the part of the truss, which is positioned in the hole area, to generate two first sub-trusses, wherein the hole is positioned between the two first sub-trusses. And under the condition that the end part of the first sub-truss, which is close to the hole opening area, meets the truss resetting condition, generating a second sub-truss based on the first sub-truss, wherein the end part of the second sub-truss, which is close to the hole opening area, is the truss peak position or the truss valley position of the second sub-truss.

For example, if the bottom plate for preparing the laminated slab has the hole, the obtained modeling information of the laminated slab may further include hole modeling data, and when it is determined that the truss and the hole area defined by the hole modeling data are overlapped, the part of the truss located in the hole area is removed, so as to generate two first sub-trusses, where the hole is located between the two first sub-trusses.

Fig. 10 is a schematic diagram illustrating a first sub-truss structure that does not satisfy the truss resetting condition according to an exemplary embodiment of the present application, where as shown in fig. 10, white squares indicate an opening area 100 overlapping with trusses, and after removing a portion of the trusses located at the opening area 100, a first sub-truss 210 is generated, where the first sub-truss 210 includes a first sub-truss 211 located on the left side and a first sub-truss 212 located on the right side, and the opening area 100 is located between the first sub-truss 211 located on the left side and the first sub-truss 212 located on the right side.

In an alternative manner, if it is determined that the end of the first sub-truss near the opening area does not satisfy the truss resetting condition, two first sub-trusses may be generated by directly removing the portion of the truss at the opening area.

And if the end part of the first sub-truss, which is close to the opening area, meets the truss resetting condition, generating a second sub-truss based on the first sub-truss, wherein the end part of the second sub-truss, which is close to the opening area, is the truss peak position or the truss valley position of the second sub-truss.

For example, in order to conveniently process the truss in a factory, achieve production standardization of the truss and improve processing efficiency, it is further necessary to determine a structure of the end portion of the first truss near the opening area to determine whether the end portion of the first sub-truss near the opening area meets a truss resetting condition. Based on the above, the truss resetting condition can be that the end part of the first sub-truss near the hole opening area is shifted from the truss peak position or the truss valley position of the first sub-truss, and the length of the first sub-truss is the same as that of the second sub-truss.

For example, as shown in fig. 10, the right end of the left first sub-truss 211 near the opening area is the truss peak position, and the left end of the right first sub-truss 212 near the opening area is the truss valley position, which do not satisfy the truss resetting condition, so that the second sub-truss does not need to be regenerated based on the first sub-truss, and the first sub-truss can be directly used for the standardized production process.

Fig. 11 illustrates a schematic diagram of a resetting process of a first sub-truss satisfying a truss resetting condition according to an exemplary embodiment of the present invention. As shown in fig. 11, when the right end of the left first sub-truss 211 close to the opening area 100 is adjacent to the truss peak position but is not coincident with the truss peak position, the truss resetting condition is satisfied, and therefore, the left second sub-truss 221 needs to be regenerated based on the left first sub-truss 211, so that the right end of the left second sub-truss 221 close to the opening area 100 is the truss peak position, and the length of the left first sub-truss 211 is the same as that of the left second sub-truss 221.

As shown in fig. 11, when the left end of the right-side first sub-truss 212 close to the opening area 100 is adjacent to but not coincident with the truss valley position, the truss resetting condition is satisfied, and therefore, it is necessary to regenerate the right-side second sub-truss 222 based on the right-side first sub-truss 212, the left end of the right-side second sub-truss 222 close to the opening area 100 is the truss valley position, and the length of the right-side first sub-truss 212 is the same as that of the right-side second sub-truss 222.

In one example, when the bottom plate has an opening, the modeling information of the laminated slab further includes opening modeling data, the truss includes two sub-trusses, and the opening is located between the two sub-trusses; the distribution mode of the target hoisting points at least comprises the positions of the target hoisting points and the truss marks to which the target hoisting points belong. At this time, the target hoisting point position is determined based on modeling information of the truss under the condition that the portion located at the opening of the cave is not removed from the truss, and therefore, after determining the distribution mode of at least two target hoisting points of the same truss from the multiple candidate hoisting point positions based on the two first theoretical hoisting point areas, the method according to the exemplary embodiment of the present invention further includes: and under the condition that the target hoisting point position is overlapped with the opening area defined by the opening modeling data, adjusting the target hoisting point position to the truss peak position of one sub-truss. The distance between the peak position of the truss of the sub-truss and the end part of the sub-truss close to the opening area is larger than or equal tod/2+kAnd is less than or equal tod+k. For example:kmay be greater than or equal to 0 and less than or equal todThe value of/2.

In practical application, the distribution mode of the target hoisting points at least comprises the positions of the target hoisting points and the identifications of the trusses to which the target hoisting points belong. If the position of the target hoisting point needs to be adjusted, the identification of the truss to which the target hoisting point belongs can be obtained firstly, the truss to which the target hoisting point belongs is determined based on the identification of the truss to which the target hoisting point belongs, and the position of the target hoisting point is adjusted on the truss, so that the dynamic adjustment of the position of the target hoisting point in the area of the portal is realized, the actual production requirement is met, and the hoisting point arrangement efficiency is high.

Defining the distance between the position of the truss wave crest of the sub-truss and the end part of the sub-truss close to the opening area as a target hoisting point adjusting area, considering that the end part of the sub-truss close to the opening area deviates from the position of the truss wave crest or the position of the truss wave trough when the machining precision of the end part of the sub-truss close to the opening area is not high, and utilizing an error coefficientkAnd adjusting the offset degree of the end part of the sub-truss close to the opening area and the peak position or the trough position of the truss to adjust the length of the target lifting point adjusting area, thereby further ensuring that the peak position of the truss of the sub-truss falls into the target lifting point adjusting area and further providing a selection basis for the position adjustment of the target lifting point.

And when the position of the target hoisting point in the opening area is adjusted, adjusting the target hoisting point to the position of the truss wave crest of the sub-truss closer to the opening area. And if the distances between the target hoisting point and the ends, close to the opening area, of the two sub-trusses are equal, adjusting the position of the target hoisting point to the truss wave crest position of the sub-truss on the right side of the opening area.

For example, fig. 12 is a schematic diagram illustrating a target suspension point position adjustment process according to an exemplary embodiment of the present invention. As shown in FIG. 12, if there is a target hanging point located in the opening area 100, and the original target hanging point location in the opening area 100cThe distance from the right end of the left second sub-truss 221 is deltad ₃ Original target hanging point position in the opening area 100cA distance delta from the left end of the right second sub-truss 222d ₄ . It should be understood that shown in FIG. 12cRepresenting only the target hanging point position within the opening area 100 and not representing the actual position of the target hanging point within the opening area 100, i.e., the original target hanging point positioncIt is sufficient to locate the hole area 100. At this time, the original target hoisting point positioncThe distance from the right end of the left second sub-truss 221 is Δd ₃ Represents, originalStarting target hoisting point positioncDistance Δ from left end of right second sub-truss 222d ₄ And (4) showing.

If Δd ₃ Less than Δd ₄ And because the right end part of the left second sub-truss 221 close to the opening area 100 is the truss peak position, the position of the target hoisting point can be adjusted to the second truss peak position counted from right to left at the right end part (close to the opening area 100) of the left second sub-truss 221, and the truss peak position is taken as the adjusted target hoisting point positionM ₃ The position of the target suspension pointM ₃ The distance from the right end of the left second sub-truss 221 is equal tod+k。

If Δd ₃ Greater than deltad ₄ And because the left end part of the right second sub-truss 222 close to the hole area 100 is the truss trough position, the position of the target hoisting point is adjusted to the first truss peak position counted from left to right of the left end part (close to the hole area 100) of the second sub-truss 222, and the truss peak position is the adjusted target hoisting point positionM ₄ The position of the target suspension pointM ₄ The distance from the left end of the right second sub-truss 222 is equal tod/2+k。

If Δd ₃ Is equal to deltad ₄ Adjusting the position of the target hoisting point to the position of the first truss peak counted from left to right at the left end (close to the entrance area 100) of the second sub-truss 222 at the right side, and taking the truss peak position as the adjusted position of the target hoisting pointM ₄ The position of the target suspension pointM ₄ The distance from the left end of the right second sub-truss 222 is equal tod/2+k。

In one example, after determining distribution patterns of at least two target suspension points of the same truss from a plurality of candidate suspension point positions based on two first theoretical suspension point areas, the method of the exemplary embodiment of the present invention further includes:

determining that the number of the truss peaks of one sub-truss is greater than or equal to the preset number of the peaks, and certainly determining that the position of the truss peak of one sub-truss is close to the target hoisting point. Even the number of the truss wave crests of one sub-truss is determined to be larger than or equal to the preset number of the wave crests, and the position of the truss wave crest of one sub-truss is close to the target hoisting point position.

Aiming at the situation that the target hoisting point is located in the opening area, the target hoisting point needs to be adjusted to a truss wave crest position of a sub-truss located on two sides of the opening area, the number of truss wave crests contained in the sub-truss enables the target hoisting point to be arranged on the truss sub-truss, the sub-truss can be guaranteed to bear the weight of the laminated slab, and meanwhile, the laminated slab can be guaranteed to be symmetrically stressed and not deformed in the hoisting process.

When the number of the truss wave crests of one sub-truss is determined to be larger than or equal to the number of the preset wave crests, and the number of the preset wave crests is larger than or equal to 3, the weight of the laminated slab can be borne by the sub-truss when the position of the target lifting point is adjusted to the position of one truss wave crest of the sub-truss, and meanwhile, the laminated slab can be symmetrically stressed and does not deform in the hoisting process.

When the situation that the position of the truss peak of one sub-truss is close to the position of the target hoisting point is determined, and the distance between the position of the truss peak of the sub-truss and the end part of the sub-truss close to the opening area is larger than or equal tod/2+kAnd is less than or equal tod+kThe sub-truss can bear the weight of the laminated slab, and meanwhile, the laminated slab can be symmetrically stressed and does not deform in the hoisting process.

In one example, the modeling information of the composite slab further includes modeling data of the base plate, the number of the trusses is at least three, and after the modeling information of the composite slab is obtained, before determining a distribution mode of at least two target hanging points of at least the same truss from a plurality of candidate hanging point positions based on two first theoretical hanging point regions, the method of the exemplary embodiment of the present invention further includes:

a bottom plate centroid position is determined based on the bottom plate modeling data, and two truss modeling data are determined from the at least three truss modeling data based on the bottom plate centroid position.

When the superimposed sheet hoists the construction, with the skew control of the barycenter of hoist and mount in-process superimposed sheet and the barycenter of superimposed sheet at certain extent, make the superimposed sheet at hoist and mount in-process symmetry atress to guarantee the stability of superimposed sheet at the hoist and mount in-process, prevent the condition that the superimposed sheet turned on one's side, avoid taking place the incident.

The center of mass of the laminate can be determined based on the density, volume, and mass of the laminate. The center of mass of the superimposed sheet may be determined based on the center of mass of the bottom plate. Thus, the baseplate centroid position may be determined based on the modeling data of the baseplate.

In an exemplary embodiment of the present invention, the number of the trusses is at least three, and after the determination of the centroid position of the base plate, modeling data of two trusses is determined from modeling data of the at least three trusses based on the centroid position of the base plate.

Illustratively, in the width direction of the trusses, an upper truss and a lower truss which are symmetrical along the center of mass of the laminated slab are determined as the trusses on which the hoisting points are arranged. After the distribution mode of the lifting points on one truss is determined, the truss which is symmetrical on the laminated slab and is closest to the edge of the laminated slab and the distribution mode of the lifting points on the truss can be searched in the width direction of the truss by taking the mass center of the laminated slab as a symmetrical center.

In practical application, when the bottom plate has openings such as notches and holes, the centroid of the bottom plate is not necessarily located at the geometric center of the bottom plate, and at this time, the distance between one truss symmetrical to the centroid of the composite slab and the adjacent side edge of the bottom plate is not necessarily equal to the distance between the other truss and the adjacent side edge of the bottom plate.

Aiming at the laminated slab with a plurality of holes and complex geometric modeling with gaps, the framework of the laminated slab member at least comprises bottom plate framework ribs and truss framework ribs, the ribs are large in quantity, various in types and complex in position, and the problems that the positions of the ribs with different views are disordered, the ribs are lost and the laminated slab is not visual enough are often caused. In order to solve the problem, the exemplary embodiment of the present invention visually identifies the bottom plate framework ribs, the truss framework ribs, the target hoisting point positions and the hoisting point reinforcing ribs when determining the hoisting point distribution mode of the composite slab.

In practical application, the visual identifier can be customized according to user needs, and can be various identification information such as color identifiers, data identifiers, symbol identifiers (such as hollow circles, solid triangles and the like). And importing the modeling information of the superimposed sheet into visual modeling software (such as two-dimensional or three-dimensional modeling software), so that the superimposed sheet skeleton is visually displayed in the canvas preview. For example, supposing that the bottom plate framework ribs and the truss framework ribs contained in the laminated slab framework can be visually displayed, the bottom plate framework ribs, the truss framework ribs and the hanging point reinforcing ribs can be rendered in different colors, and the target hanging point position is rendered in a triangular symbol, so that the situation that the same laminated slab framework contains the bottom plate framework ribs, the truss framework ribs and the hanging point reinforcing ribs and the hanging point distribution mode of the laminated slab is visually observed.

Illustratively, fig. 13 shows a schematic view of visual identification of a distribution manner of superimposed slab hanging points according to an exemplary embodiment of the present invention. As shown in fig. 13, the bottom plate frame ribs 131 can be visually marked as red, the truss frame ribs 132 can be visually marked as black, the target hanging point position 133 can be visually marked as a green solid triangle, and a group of hanging point reinforcing ribs 134 located on both sides of the target hanging point 133 can be visually marked as green. Meanwhile, as can be seen from fig. 13, the exemplary embodiment of the present invention arranges the target hanging points 133 on the two girders 132 positioned at the outermost edges of the composite slab and symmetrical in the girder width direction.

In practical application, the laminated slab needs to be hoisted by a crane in the installation process, and in the hoisting process, the laminated slab member needs to be hoisted at the target hoisting point position of the truss by using a hoisting hook of the crane. Based on the above, in the exemplary embodiment of the invention, a group of lifting point reinforcing ribs can be designed at the position of the bottom plate corresponding to the target lifting point, and the position of the target lifting point is locally reinforced by using the lifting point reinforcing ribs, so that the truss is prevented from deforming at the position of the lifting point, the lifting requirement of the laminated slab is met, and the automatic arrangement of the lifting point reinforcing ribs is realized. Meanwhile, if the position of the target lifting point is located in the area of the opening, the dynamic adjustment of the reinforcing ribs of the lifting point cannot be realized. As shown in fig. 13, two suspension point reinforcing bars 134 may be disposed at both sides of the target suspension point 133 in the truss width direction.

It should be noted that, for different types of laminated slab members, when determining the hanging point distribution manner, each type of laminated slab member needs to establish its own processing policy base (which may be referred to as a rule base). When the hoisting point distribution mode determining method of the exemplary embodiment of the present invention is used for determining the hoisting point distribution mode of a superimposed slab, parameters related to the hoisting point distribution mode determining method may be set on a visualization parameter setting interface (such as a visualization editing interface shown in fig. 13) of a rule base according to user requirements. The parameters related to such a method for determining the distribution of suspension points include, but are not limited to: the method comprises the following steps of overlapping plate type, bottom plate quality, bottom plate volume, bottom plate density, opening type, notch type, truss type, lifting point reinforcing rib type, rib parameter, truss wave crest interval, truss length, truss width, target lifting point number, position adjusting parameter, bottom plate visual identification, data editing operation (adding, deleting, changing, moving and the like) and the like.
