In step 130, the reinforcement bar arrangement modeling scene in the BIM is restored to be a field real construction scene, and the problems existing in the reinforcement bar arrangement modeling scene are found and solved.

Specifically, the reinforcement bar arrangement modeling scene in the BIM is restored to a field real construction scene, the real construction condition is checked in the real construction scene, the reinforcement bar arrangement and construction problems are found, the corresponding reinforcement bar problems are analyzed, and the problems are solved.

Specifically, in one embodiment of the present application, the restoring the rebar arrangement modeling scene in the BIM three-dimensional model to a field real construction scene, searching and solving the problem existing in the rebar arrangement modeling scene, includes:

Specifically, the solution method for solving the problem that the main reinforcement bar at the corner of the steel beam cannot be normally anchored into the support comprises the following steps:

Specifically, the beam main reinforcement is calculated according to the sizes of the beam column and the main reinforcement, the beam main reinforcement bending avoidance distance is determined, the bending position of the reinforcing steel bar is determined through calculating the bending angle of the reinforcing steel bar, the bending position of the reinforcing steel bar is calculated and determined, the collision position is avoided, the bending angle of the reinforcing steel bar is considered, and the corner part of the beam is provided with a constructional reinforcing steel bar, so that the diameter of a tie reinforcing steel bar of the beam stirrup is not less than the diameter of the stirrup.

Specifically, the solution method for solving the problem that concrete cannot be poured into the concrete due to the reinforcement density of the steel bars comprises the following steps:

Specifically, because the reinforcing bar reinforcement density is big, lead to the unable abundant filling of concrete to tamp, frame beam, the conversion volume, the post of rising on the roof beam, position Liang Peijin is all bigger, roof beam upper portion reinforcement root number is more, lead to the reinforcing bar interval less, the vibrating rod can't reach the constitution deeply, the concrete is not in place to vibrate, the phenomenon of uncompacted can appear in the concrete, hole can appear in serious concrete, influence concrete intensity, can produce very big influence to the quality of concrete, the reinforcing bar is intensive simultaneously can lead to the concrete segregation phenomenon, lead to concrete cementing material (mainly cement) and aggregate (grit) separation, can appear the hole in the concrete, uncompacted, the concrete intensity level can not reach the requirement phenomenon, can produce very big influence to the quality of concrete, then also produce very big influence to the atress between concrete and the reinforcing bar, cause the quality potential safety hazard of overall structure.

The processing mode for this case is: and calculating the arrangement space of the reinforcing steel bars, calculating the maximum diameter of aggregate and the diameter of the vibrating rod according to the grade of concrete, and determining the minimum vibration space of the arrangement space of the reinforcing steel bars through calculation. And reducing the number of the steel bars according to the minimum spacing of the arrangement of the steel bars, calculating the stress coefficient of the layer of steel bars, determining the proportion of the steel bars at the position to the concrete, and increasing the diameter of the steel bars at the position or increasing the number of the steel bars according to the calculation result so as to meet the stress condition at the position and meet the concrete pouring requirement.

Specifically, the solution method for solving the problem that concrete cannot be poured into the reinforced concrete structure core node position due to additional reinforcement comprises the following steps:

Specifically, the core node position of the steel structure concrete structure is reinforced by the additional reinforcement, concrete cannot be fully poured into the tamping, the core node position of the beam column of the steel structure concrete body is blocked by the anchor plate after the anchor plate is added to extend into the construction, the concrete is not vibrated in place, the concrete can be subjected to the phenomenon of incompact, holes can be formed in serious concrete, the strength of the concrete is affected, and the quality of the concrete is greatly affected.

The processing mode for this case is: and (3) calculating the tensile force and the pressure born by the concrete at the position of the reinforced bar node and the concrete at the bottom to determine the strength of the concrete, and calculating the position solidification relation between the self-compacting concrete and the conventional concrete joint by using the self-compacting concrete meeting the stress condition instead, so as to calculate and determine the casting volume of the self-compacting concrete to ensure the construction quality of the position.

Specifically, when a steel bar collides with a steel structure, connection is needed to be constructed with the steel structure, and a connection mode is selected according to the collision position of the steel structure and the steel bar, wherein the solution of the collision of the steel bar and the steel structure comprises five modes, namely sleeve connection and stiffening plate connection; thirdly, the opening penetrates, fourthly, the steel bar is bent to be anchored, and thirdly, the haunching avoidance steel member is added.

Specifically, firstly, adopt steel construction welding sleeve and the mode of reinforcing bar connection, solve the problem that reinforcing bar and steel construction bump, include:

And (3) reinforcing steel plates at the left sides of the welding sleeve positions of the steel structure, and calculating the thickness of the reinforcing steel plates according to corresponding stress, so as to meet the stress requirement of the steel structure at the positions.

Specifically, steel construction welding sleeve is connected with the reinforcing bar, adopt telescopic joint to pay attention to, check whether sleeve number and reinforcing bar number are unanimous, sleeve diameter and reinforcing bar diameter are unanimous, on-the-spot reinforcing bar processing reinforcing bar screw thread makes it correspond with the sleeve screw thread, in order to avoid unable installation, it appears the atress inequality to need prevent to weld sleeve position both sides, the problem of weakening is weakened to static load intensity, in steel column welding sleeve position, the sleeve position reinforcing bar receives compressive strength and tensile force intensity should be calculated, in order to calculate this position steel column static load intensity and tensile force intensity and weaken the relation, according to static load intensity and tensile force intensity weaken the relation, the reinforcing steel sheet should be done at welding sleeve position both sides, calculate the reinforcing steel sheet thick end according to corresponding atress relation, in order to satisfy this position steel column atress.

When the two sides of the beam steel bar are connected by the sleeve, if the steel bar cannot normally use mechanical connection, the beam steel bar can be connected by adopting an electroslag pressure welding head for lap joint after disconnection and installation, and also can be connected by adopting a double-screw sleeve lap joint.

Specifically, secondly, adopt steel construction welding stiffening plate and the mode of reinforcing bar connection, solve the problem that reinforcing bar and steel construction bump, include:

and determining the strength of the concrete, and using the self-compacting concrete meeting the stress condition.

Specifically, steel construction welding stiffening plate is connected with the reinforcing bar, adopts the stiffening plate to be connected and need pay attention to, reinforcing bar and welding minimum length, and the stiffening plate should not be less than minimum welding length, probably leads to vibrating rod unable deep into in the node core area after the steel column increases the stiffening plate, and the concrete can not fully tamp, need change reinforcing bar node position concrete into the use from compact concrete this moment to guarantee this position construction quality. If there are the condition of multi-row main muscle, can only set up one deck stiffener, set up multi-row stiffener and probably lead to stiffener interval too little, the concrete can not fully fill, and the interval is less simultaneously probably to lead to the reinforcing bar unable welding operation.

Specifically, thirdly, adopt steel construction trompil reinforcing bar to directly pass the steel construction and normally anchor into the mode of overlap joint, solve the problem that reinforcing bar and steel construction bump, include:

And calculating the stress relation after the steel structure is perforated at the perforated position and the weakening relation of the material strength, and increasing the strength of the perforated position.

Specifically, the perforated steel bar of the steel structure can directly pass through the steel structure to be normally anchored and lapped, the steel structure is perforated to calculate the aperture ratio of the steel structure according to the number of the perforated holes, the bending moment, shearing force, constraint force and material strength of the perforated position of the steel structure are calculated, and the stress relation and material strength weakening relation of the steel structure after the perforated holes are calculated according to the perforated holes, so that the perforated positions of the steel structure are correspondingly reinforced. When the punching operation is carried out on part of stirrup drag hook ribs and the holes of the steel structure, the conventional 180-degree steel bar hook processed by the steel bar cannot normally pass through, one side of the hook is processed into a 90-degree hook, and after the steel structure is punched, the hook is processed into 180 degrees by secondary processing.

Specifically, fourth, adopt curved anchor mode, solve the problem that reinforcing bar and steel construction bump, include:

setting the bending anchor length and bending length of the steel bar;

and calculating the bond strength of the concrete at the connection position of the steel bar and the steel structure bent anchor, so that the bond strength of the concrete meets the requirement.

Specifically, when the steel bar and the steel structure collide with the steel bar and can not be directly anchored, if the requirement of bending the steel bar is met, the bending treatment can be directly carried out, the length of the rest straight anchor section after the steel bar is bent is more than 0.4 times of the length of the total straight anchor, the bending length is not less than 15 times of the diameter of the steel bar, and whether the bond strength of the concrete at the position can be met is calculated. When the frame beam takes the frame column as a support, attention is paid to the fact that the anchor length of the frame beam is 5 times larger than the diameter length of the steel bar of the central line of the column while the straight anchor length of 0.4 times of the diameter of the steel bar is met according to the requirements of design specifications.

Specifically, fifthly, adopting the form of adding beam horizontal haunching to avoid the steel bar, directly anchoring after avoiding the steel structure, solving the problem that the steel bar collides with the steel structure, comprising:

Specifically, the main beam part rib collides with the steel column to avoid the steel bar in a mode of increasing the horizontal haunching of the beam, the steel bar can be directly anchored after the steel structure is opened, the avoidance angle of the steel bar is calculated to determine the avoidance distance of the steel bar, the avoidance distance of the steel bar is smaller than the distance from the beam edge to the column edge, the horizontal haunching can be performed, the ratio of the long side to the short side of the haunching is not greater than 1:4, the haunching steel bar is increased, and the diameter of the haunching steel bar is not smaller than that of the steel bar at the same position. The beam steel bar avoiding position should calculate whether the stress of the concrete is excessive or not, and if the stress concentration problem occurs at the position, the construction steel bars should be added at the position to avoid the stress concentration.

In step 140, according to the problems in the examined reinforcement arrangement modeling scene, the reinforcement arrangement modeling scene is optimized, and construction deduction is performed on the corresponding complex reinforcement nodes by the construction process of the building project.

Specifically, according to the construction scene of specific complicated reinforcing bar node, for example, first post main muscle has to cut, and collision adopts the gusset welded connection with the girder steel. And the column stirrups at the second complex steel bar joint point are required to be broken after being collided with the steel beam bracket in the range, and then are welded with the connecting plate. And the third beam steel bar collides with the steel structure column, and a lap joint mode is selected according to related conditions. And the fourth welding sleeve mode is connected with the main rib, the connection between the welding sleeve at the position and the beam main rib is used for calculating the weakening relation between the static load strength and the tensile strength, and reinforcing steel plates are used at two sides of the welding sleeve position. The fifth connecting plate is connected with the steel column in a welding mode. The sixth beam rib needs to be anchored into the node after the bending anchor position is adjusted or the bending is properly performed according to the condition of the node. By the method, the construction deduction scene of the complex steel bar node can be constructed.

In step 150, according to the optimized reinforcement arrangement modeling scene and the construction result of construction deduction on the corresponding complex reinforcement nodes in the construction project construction flow, the BIM three-dimensional model is subjected to construction animation according to the construction deduction scheme.

Specifically, aiming at the construction modeling scene of the steel bar arrangement which is optimized and the construction result of construction deduction of the corresponding complex steel bar nodes by the construction process of the building project, a professional graphic video software is used for carrying out construction animation production according to the construction deduction scheme, the video construction scheme is consistent with the construction deduction scheme, and the construction instruction animation consistent with the field process is completed.

In step 160, a multi-department collaborative review is performed on the optimized reinforcement arrangement modeling scene, the construction deduction result of the complex reinforcement nodes and the construction animation production result, and a consistency construction drawing is obtained.

Specifically, the optimized reinforcement arrangement modeling scene, the construction deduction result of the complex reinforcement nodes and the construction animation production result are subjected to multi-department collaborative consultation. The design department, the supervision department and the construction department conduct consultation and protection, and after the departments agree, the corresponding construction drawing and explanation are provided.

In step 170, cloud model making is performed on the reinforcement arrangement modeling scene, the construction deduction result, the construction animation production result and the consistency construction drawing by using BIM three-dimensional model software, so as to generate a final complex reinforcement node design model.

Specifically, BIM three-dimensional model software is used for cloud model production of the reinforcement arrangement modeling scene, the construction deduction result of complex reinforcement nodes, the construction animation production result and the consistency construction drawing, and the BIM system software is used for automatically generating a graphic two-dimensional code so as to meet the requirement that a three-dimensional model can be directly checked after a mobile terminal is directly adopted to scan the two-dimensional code on a construction site, and construction animation, related drawings and description are carried out.
