Description

  The present invention relates to a structure examination system and a structure examination program for examining installation of a tower crane in construction work.

  When installing a tower crane in construction work, it is necessary to examine the structural safety, and RC formwork support work needs to be confirmed by structural calculation. Conventionally, structural calculation systems have been used for safety studies. With reference to FIG. 3, the processing operation of the safety examination using the structural calculation system according to the prior art will be described. FIG. 3 is a block diagram showing a configuration of a conventional structural calculation system.

  First of all, the workers should consider the design information such as blueprints, specifications and questions, and the construction information such as process schedules, construction instructions, construction drawings, temporary design drawings, and equipment information, and examine them manually. Create a model. Then, the created model data for examination is manually input to the structure calculation unit 40 configured by a personal computer or the like. The structure calculation unit 40 performs structure calculation based on the input model data for examination and data such as standard dimensions, cross-section information, and strength stored in the material database 60. Then, the structure calculation unit 40 determines whether or not safety is satisfied based on the obtained structure calculation result, and outputs a determination result (OK or NG). The worker confirms safety based on the determination result of whether or not the safety of installation of the tower crane is satisfied by such processing operation. If the safety is not satisfied, the same processing operation is repeated until the safety is satisfied.

In addition, as a prior art, in order to automatically create a crane plan that can be applied to the construction of a structure frame, the position, posture, and lift of the crane used in the construction work of the structure in the construction planning field are calculated by a computer. A method of planning a heavy performance / member conveyance route is known (for example, see Patent Document 1).

However, the conventional structural calculation system has the following problems.
(1) An operator must input load conditions such as crane specifications, arrangement, frame dimensions, reinforcement method, etc., which is troublesome.
(2) Since the shape of the building under construction changes constantly, the load conditions also change accordingly. Therefore, it is necessary to examine the stability by assuming a state in the middle of the process. It is difficult to take a close response to the change due to such constraints.
(3) Failure to assume important load conditions could lead to serious accidents in actual construction.
(4) The calculation system only makes a pass / fail judgment based on the result calculated based on the set conditions. Therefore, in order to make a reasonable plan, the building reinforcement method is changed variously and repeated calculations are performed. It must be troublesome.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a structure examination system and a structure examination program capable of examining installation of a tower crane in construction work with minimal manual work. .

Possible to perform the member selection step of selecting the reinforcing member capable of satisfying the safety come to the computer and said.

  According to the present invention, the structural safety of the tower crane is automatically examined based on the information on the building where the tower crane is installed and the construction plan information for constructing this building, and rationalized as necessary. Since an effective reinforcement method can be planned, it is possible to study the installation of a tower crane in construction work with minimal manual work.

  Hereinafter, a structure examination system according to an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 4 denotes a structure calculation unit that inputs data of the study model created in the study model creation unit 1 and performs a structure calculation based on the input data. Reference numeral 5 denotes a printer that prints information on a structure calculation result calculated by the structure calculation unit 4. Reference numeral 6 is a building material database in which characteristic data of building materials is stored in advance, and standard dimensions, cross-sectional information, strength, and the like are stored therein. Reference numeral 7 denotes a building information database in which data of a building where the tower crane is installed is stored.

Reference numeral 8 denotes a construction plan information database in which construction plan data is stored, and process data, construction procedure data, construction drawing data, provisional design data, used equipment data, and the like are input and stored during construction planning.

  Next, with reference to FIG. 2, the processing operation of the examination model creation unit 1 and the structure calculation unit 4 shown in FIG. 1 will be described. First, when an operator operates the input unit 2 and gives an instruction to start a safety study of the tower crane, the study model creation unit 1 reads the specifications of the tower crane to be used from the construction plan information database 8. Obtain (step S1). The specification data acquired here are the tower crane manufacturer, model, head, boom length, number of masts, base dimensions, and the like.

  Next, the examination model creation unit 1 acquires the reaction force of the foundation part by reading it from the building material database 6 (step S2). Subsequently, the examination model creation unit 1 reads and acquires the arrangement information (planar dimensions) of the tower crane from the construction plan information database 8 and the building information database 7 (step S3). The information acquired here is information such as the core dimension in the X direction, the core dimension in the Y direction, the receiving beam plane position, and the base plane position.

  Next, the study model creation unit 1 passes the acquired information to the structure calculation unit 4. In response to this, the structure calculation unit 4 calculates the load acting on the receiving beam (step S4), and outputs the result to the study model creation unit 1. Since this load calculation is the same as the conventional calculation method, detailed description is omitted. Subsequently, the study model creation unit 1 calculates the load acting on the receiving beam by back-calculating the member cross section used for the receiving beam from the allowable stress level and the deflection amount based on the calculation result (step S5). Then, the study model creation unit 1 refers to the building material database 6 and selects a receiving beam equal to or greater than the required cross section (cross section obtained by back calculation) (step S6). By this processing operation, the cross section of the receiving beam is determined (selected).

  Next, the examination model creation unit 1 reads out and acquires process information from the construction plan information database 8 (step S7). And the examination model preparation part 1 sets the condition for every construction stage automatically with reference to the acquired process information (step S8). Subsequently, the study model creation unit 1 reads and acquires the steel frame information of the building body from the building information database 7 (step S9).

  Next, the examination model creation unit 1 repeats the processes of steps S10 to S13 only the same number as the number of construction stages. The study model creation unit 1 first passes to the structure calculation unit 4 information on the situation (steel frame information of the building body) for each construction stage and information necessary for the structure calculation when the construction stage is STEP 1. In response to this, the structure calculation unit 4 calculates the stress level of the building body, determines pass / fail from the calculation result, and returns the determination result and the obtained stress level value to the study model creation unit 1. Since the method for calculating the stress level of the building body is the same as the conventional calculation method, detailed description thereof is omitted.

  The examination model creation unit 1 refers to this pass / fail judgment result, and if it is “OK”, does not execute the next step (step S11). On the other hand, if the acceptance / rejection determination result is “NG”, the study model creation unit 1 calculates a necessary reinforcing member from the calculated value of the stress level by back calculation (step S12). Thereby, if reinforcement is necessary at the construction stage of STEP 1, the reinforcement member to be reinforced is calculated by back calculation. The back calculation of the reinforcing member is performed by referring to the building member database 6 and selecting an appropriate reinforcing member (which can reinforce the building strength and is the most economical) based on the obtained stress value. Done.

  Next, the study model creation unit 1 passes the information on the status of each construction stage (steel frame information of the building body) and the information necessary for the structural calculation when the construction stage is STEP 2 to the structural calculation part 4 to construct the structure. The processing operation of performing calculation and performing pass / fail judgment is repeated until the final construction stage (STEPn). When the final construction stage study result is obtained, the study model creation unit 1 and the structure calculation unit 4 output the drawing output and the calculation sheet to the printer 5 based on the obtained final construction stage study result information. (Step S14).

  In this way, the structural safety of the tower crane is automatically examined based on the information on the building where the tower crane is installed and the construction plan information when constructing this building. Since the reinforcement method is planned, it is possible to easily consider the installation of a tower crane in construction work with minimal manual work. In addition, the building information and the construction plan information are stored in the database, and when necessary, the examination model creation unit 1 automatically reads out and acquires the building information and the construction plan information. Manual input can be omitted, the operator's workload can be reduced, and the effort required for planning can be greatly reduced. In addition, since the structural calculation corresponding to the construction stage is executed, it is possible to prevent an examination error by the operator from occurring.
