It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1, the present embodiment provides a method for refining the amount of reinforcement of a raft foundation slab band based on BIM modeling, when performing BIM modeling on a raft foundation slab with reinforcement, the method includes the following steps:

Specifically, according to the design requirements of the drawing, a raft foundation member and a shear wall member are established. When the raft foundation component and the shear wall foundation are established, the thickness and elevation of the shear wall foundation are the same as those of the raft foundation.
In particular, when building raft foundations and shear wall foundations, the edges of the shear wall foundations are flush with the edges of the raft foundations.
Specifically, the raft foundation member is divided when the raft foundation member and the shear wall member are established.
In particular, when dividing the raft foundation member, the range division is performed according to the length of the slab band reinforcing bars within the raft foundation, and the edge portions of the raft foundation are separated from the entire raft foundation, forming the arrangement range of the slab band reinforcing bars.
Specifically, when defining and drawing the plate band reinforcing ribs, attribute editing is performed on the plate band reinforcing ribs.
Specifically, after attribute editing is performed on the panel strip reinforcing ribs, node requirements of the panel strip reinforcing ribs are set.
In particular, when the joints of the slab band reinforcing bars are arranged, the length of the slab bottom bars extending into the wall member at the lower side of the non-overhanging end part of the raft foundation is modified, and the anchoring length of the reinforcing bars is modified.
Specifically, after the definition of the plate and strip reinforcing ribs is finished, the plate and strip reinforcing ribs are arranged and summarized, engineering data are acquired, and then the plate and strip reinforcing ribs are locked by using a locking function, so that subsequent operation is prevented, and the length of the plate and strip reinforcing ribs is changed.
Specifically, the raft foundation is elongated according to the design requirement of the drawing so that the raft foundation exceeds the shear wall foundation by 500mm.
It can be seen that the problem that the modeling calculation of additional reinforcing steel bars such as plate and strip reinforcing steel bars cannot be performed by conventional methods and functions in BIM modeling in the current market is solved by flexibly applying BIM modeling and fine-tuning methods of the reinforcing steel bars. By adopting the method for creating BIM modeling calculation, the length of the bent anchor of the reinforcing steel bar is edited and adjusted according to the node mark of the drawing, so that BIM modeling is attached to field production practice, and the problem that the existing BIM electric calculation software cannot directly draw and calculate additional reinforcing steel bars through the existing functions and methods is solved. The complex engineering calculation work is changed into simple and orderly work, the work efficiency is greatly improved, the work intensity of budgeting staff is reduced, accurate engineering quantity data are provided for all parties involved in construction engineering, the cost and the control investment are effectively saved, the huge market demand is met, the optimization thought of functions of BIM electric calculation software development engineers is provided, and the update of the BIM electric calculation software on the function application is facilitated.
The method of the embodiment aims at the problem that the existing BIM electric calculation software cannot process complex node building components through conventional functions, and aims at drawing sporadic, unconventional and complex building components through BIM electric calculation technology through flexible combination and application of a modeling method, and the integrity and accuracy of the steel bar engineering quantity of the sporadic, unconventional and complex building components are guaranteed. And the BIM electric calculation software development engineer is provided with an optimization idea of the functions of the BIM electric calculation software development engineer, and the BIM electric calculation software development engineer is beneficial to upgrading the BIM electric calculation software on the function application.
When the embodiment is specifically implemented, as shown in fig. 2, the raft foundation member and the wallboard-tape reinforcing ribs are used for finely adjusting the reinforcing steel bars through BIM modeling to meet the requirements of drawing nodes and specifications, so that the accurate data of the concrete engineering quantity of the reinforced template are obtained. And (3) carrying out BIM modeling of reinforced civil engineering integration, carrying out fine splitting on the raft foundation member and the wallboard belt reinforcing rib structure diagram for facilitating the visualization of the model, wherein the raft foundation member and the external wallboard belt reinforcing rib C16@150 extend into the base layer for bending 3820mm, and the board belt reinforcing rib at the bottom of the outer wall is bent up 1460mm (with the thickness of a bottom board of 600 mm). The method can be implemented in the following ways:
1. referring to fig. 3, according to the design requirements of the drawing, firstly, building a raft foundation member and a shear wall member, wherein the foundation thickness and elevation of the shear wall member are equal to those of the raft foundation member, the foundation edge of the shear wall member is equal to the edge of the raft foundation member (the raft foundation member forms a non-overhanging structural edge), then, adopting a dividing function to divide the range according to the length (3820 mm) of the plate-band reinforcing rib in the raft foundation, and separating the edge part of the raft foundation from the integral raft foundation to form the arrangement range of the plate-band reinforcing rib. The method aims at forming the overall shape of the shear wall component and the raft foundation component, and making a vowel for the subsequent arrangement of the plate and strip reinforcing ribs.
2. With reference to fig. 4 and 5, the definition and drawing of the reinforcing ribs of the plate and strip are performed, and as the function of arranging the reinforcing ribs of the traditional software raft foundation has no function of arranging the overhanging structural reinforcing steel bar bending of the wall-contacting member, the purposes of drawing and refining the reinforcing ribs of the plate and strip are achieved indirectly by flexibly utilizing the reinforcing steel bar adjusting function. Firstly, performing attribute editing in the steel bar service attribute, defining a plate and strip reinforcing rib C16@150, changing the length of a plate bottom rib extending into a wall member of a raft foundation end part non-extending lower steel bar structure from 15 x d to 1460mm in the node setting in the steel bar service attribute, and changing the anchoring length of the steel bar extending into an adjacent raft foundation member to 0. After definition is completed, plate and strip reinforcing ribs are arranged at corresponding positions of a modeling interface and are summarized and calculated, a three-dimensional reinforcing steel bar model is formed, corresponding engineering data are obtained, and the plate and strip reinforcing ribs are locked by using a locking function, so that the possibility that the length of the plate and strip reinforcing ribs is changed or the arrangement positions are offset due to subsequent operation is avoided. The step is the core content of the patent, so that the arrangement position, the structural shape and the size of the plate and strip reinforcing ribs completely meet the design requirement of the drawing, the reinforcing steel bars can be displayed in three dimensions, and the engineering quantity can be conveniently checked.
3. Referring to fig. 6, an elongated raft foundation is 500mm over the shear wall foundation, forming an overhanging construction of the raft foundation. This step is to ensure the integrity of the model structure and meet the design requirements of the drawing structure size.
4. And (3) after the plate and strip reinforcing rib arrangement calculation is completed and summarized, the whole gluten, the bottom gluten and other stress reinforcing bars of the raft foundation are arranged, and the calculation is summarized. The step enables the stress bars of the integral raft foundation and the plate and strip reinforcing bars to form a complete raft foundation reinforcing mesh, which is completely consistent with the design requirements of drawings, and ensures the precision requirements and the integrity of engineering quantity.
Specifically, the difficulty of BIM modeling of the underground utility tunnel is that the existing BIM calculation software cannot directly calculate part of scattered components or additional reinforcing steel bars and dynamically display three-dimensionally through the existing modeling function and a conventional method, for example, the engineering quantity of the reinforcing steel bars of the raft foundation slab band of the utility tunnel is generally finished only through a conventional manual calculation mode or calculation results are directly input into the software, and BIM refinement calculation technology cannot be fully embodied, so that the data transmission between the later stage and a BIM5D platform is affected. Aiming at the problems, the embodiment provides an effective drawing and calculating method for the plate and strip reinforcing ribs through repeated practice of continuous exploration and research and comparison with drawings, and ensures that the three-dimensional model of the reinforcing steel bar can meet the requirements of drawing design and standard nodes. Compared with the traditional manual calculation method and a mode of directly inputting calculation results by software, the engineering calculation efficiency is greatly improved, the difference between the budgeted engineering quantity of a construction drawing and the actual field sample-turning is reduced, the short board of the operation function of the existing BIM calculation software is solved, and accurate data support is provided for all parties involved in engineering.
It can be seen that the above embodiment solves the problem that the BIM municipal calculation software in the current market cannot perform modeling calculation of additional reinforcing steel bars such as plate and strip reinforcing steel bars by using the conventional method and function by flexibly applying the BIM modeling and the fine adjustment method of the reinforcing steel bars. With the rapid development of the economy and the great improvement of the comprehensive national force in China, the decision and the confidence of the government decision layer in building the underground comprehensive pipe rack are further promoted. The scale of the currently built comprehensive pipe rack in China is small in combination with the current situation of China, and the current situation of a large gap exists compared with the scale in developed western countries, so that the potential market scale of the urban underground comprehensive pipe rack in China can be seen, once the opportunity is mature, the comprehensive pipe rack can develop at an ultra-conventional speed, and the working quality and efficiency of engineering cost keep up with the rhythm and speed adapting to the development of the comprehensive pipe rack. By the method for creating BIM modeling calculation, the length of the bent anchor of the reinforcing steel bar is edited and adjusted according to the node mark of the drawing, so that BIM modeling is attached to field production practice, and the problem that BIM calculation software cannot directly draw and calculate additional reinforcing steel bars through the existing functions and methods is solved. The complex engineering calculation work is changed into simple and orderly work, the work efficiency is greatly improved, the work intensity of budgeting staff is reduced, accurate engineering quantity data are provided for all parties involved in construction engineering, the cost and the control investment are effectively saved, the huge market demand is met, the optimization thought of functions of BIM electric calculation software development engineers is provided, and the update of the BIM electric calculation software on the function application is facilitated.
