  The design efficiency can be improved by determining the standard of the reinforcing metal fitting to be installed in the beam through hole formed in the steel beam and the range where the beam through hole can be formed using the above-described background art.

  By the way, in this type of design, at the stage of “request for study start”, the general contractor gives the parts manufacturer the specifications of the steel beam and instructs them to select the appropriate reinforcing bracket. In response to a request from a general contractor, a parts manufacturer examines a reinforcing bracket that conforms to the specifications and reports the result of the bracket review to the general contractor. At a later stage, the general contractor informs the steelworker of the metal fitting review result. The steel processor will make a concrete design of the steel beam based on the results of the metal fitting examination, and examine the suitability of the reinforcement metal fittings that have been reported. In addition, the steel processing company notifies the equipment supplier of the details of the concrete design of the steel beam created in anticipation of the metal fitting examination results. The equipment supplier will examine the concrete design details of the steel beam and the suitability of the reinforcement fittings that have received the report. If the specific design of the steel beam and the reinforcing metal fitting are suitable, the equipment supplier reports to that effect to the steel processor. The steel processor will report to the general contractor, along with the concrete design of the steel beam, if the reinforcement fittings are suitable. When a general contractor receives a report from a steelworker that a reinforcing bracket is suitable, he orders a reinforcing bracket from a parts manufacturer. This makes it possible to manufacture a steel beam with a beam through hole to which a reinforcing metal fitting is attached.

  If a parts manufacturer fails to select a reinforcing bracket that meets the steel beam specifications, this is reported to the general contractor as a “specification change request”. The general contractor gives a correction instruction to the steel processor, and the steel processor issues a correction instruction to the equipment supplier. When the specifications of the steel beam updated by the steel processor in consideration of the corrections made by the equipment supplier are reported to the general contractor from the steel processor, the general contractor returns to the above “initiation stage”, and the general contractor again sends the bracket to the parts manufacturer. Give selection instructions. If the part manufacturer cannot select a suitable reinforcing bracket despite the updated steel beam specifications, a “specification change request” is reported to the general contractor again. Catch balls for "consultation start request" and "request for specification change" between the component manufacturer, steelworker and equipment supplier, with a general contractor in between, until a reinforcement fitting that matches the steel beam specifications can be selected. As a result, design changes and reexaminations were carried out each time, and a great deal of time and manpower were consumed.

  The present invention was devised in view of the above-described conventional problems, and when performing a design to reinforce a beam through-hole formed in a steel beam web using a ring-shaped reinforcing metal fitting, a general contractor is interposed therebetween. It is possible to efficiently examine the reinforcing metal fittings made between the component manufacturer, the steel frame processor and the equipment supplier, and the design work can be done rationally and in a short time, and labor saving can be achieved. It is an object to provide a reinforcing design support system for a beam through hole.

The beam through hole reinforcement design support system according to the present invention is a beam through hole reinforcement design support system used when reinforcing a beam through hole formed in a steel beam web using a ring-shaped reinforcing metal fitting. The above system includes a reinforcing bracket database in which data of ring-shaped reinforcing brackets is stored, a fixed value drawing data input unit that reads and displays steel beam drawing data read from the drawing as a drawing fixed value, and beam penetration There is a fixed value design data input section where the design data of the hole is inputted and displayed as a design fixed value, and a determination result output section which displays a determination result of whether or not the reinforcing bracket can be attached to the steel beam. performing a calculation from the figures the fixed value and the design fixed value, one of the reinforcing bracket fits on the beam through holes in a macro read from the reinforcing bracket database, reading And mounting possibility for steel beam of the reinforcement bracket determines, the judgment result judging result of the mounting possibility to steel beam of the read reinforcing bracket to the output portion and the static spreadsheet to perform a process of displaying; the fixed value Instead of the design data input unit and the determination result output unit, it has a variable value design data input unit and a determination result update output unit, and the variable value design data input unit can rewrite the virtual value for simulating the beam through-hole. The simulation is re-calculated from the fixed values and virtual values of the drawing in the system, and one of the simulation reinforcement fittings suitable for the beam through-hole is read out from the reinforcement fitting database in a macro and read out. Judgment whether or not the reinforcing bracket can be attached to the steel beam. And dynamic spreadsheet to perform processing for updating allows displaying the determination result of the biasing possibility; stores, these static spreadsheets and dynamic spreadsheet, be sent via storable and telecommunication line to the storage medium It is characterized by being.

  In the beam through hole reinforcement design support system according to the present invention, when designing the beam through hole formed in the steel beam web with the ring-shaped reinforcing metal fitting, the general contractor is sandwiched between them. Therefore, it is possible to efficiently examine the reinforcing metal fittings made between the parts manufacturer, the steel frame processor, and the equipment supplier, and the design work can be performed rationally and in a short time, thereby saving labor. .

It is explanatory drawing of the static spreadsheet which comprises this system which shows suitable one Embodiment of the reinforcement design support system of the beam through-hole which concerns on this invention. It is explanatory drawing of the dynamic spreadsheet which shows the suitable one Embodiment of the reinforcement design assistance system of the beam through-hole which concerns on this invention which comprises the said system. FIG. 3 is a flowchart for creating static and dynamic spreadsheets shown in FIGS. 1 and 2.

  Hereinafter, a preferred embodiment of a beam through-hole reinforcement design support system according to the present invention will be described in detail with reference to the accompanying drawings. The beam through-hole reinforcement design support system according to the present embodiment is a spreadsheet that is application software, and includes a static spreadsheet 1 shown in FIG. 1 and a dynamic spreadsheet 2 shown in FIG. .

  The static spreadsheet 1 means data that is input and displayed on a sheet and data that is output and displayed as a calculation result cannot be rewritten by editing being locked.

  Dynamic spreadsheet 2 means that any data entered and displayed on the sheet is locked for editing and cannot be rewritten, while any other data entered on the sheet is unlocked for editing. Data that is rewritable and that is output and displayed as a calculation result is data that can be updated.

  As is well known, the static spreadsheet 1 and the dynamic spreadsheet 2 can be stored in any existing recording medium including a USB memory, and attached to an e-mail or posted on a homepage. It can be transmitted through a telecommunication line.

  In the present embodiment, in a network in which reinforcing metal fittings are examined between a component manufacturer, a steel processing company, and an equipment manufacturer with the above-described general contractor in between, the component manufacturer has a static and dynamic spreadsheet 1, 2 is created and provided.

  The static spreadsheet 1 has a function of presenting the reinforcing bracket selected by the component manufacturer when the specification of the steel beam and the beam through hole is shown from the general contractor to the component manufacturer at the stage of “request for study start”. . The static spreadsheet 1 provides a set of results for the “consultation start request”. As will be described later, this result includes information (“inappropriate”) that a reinforcing metal fitting that meets the specifications of the steel beam and through-hole shown cannot be selected.

  The dynamic spreadsheet 2 is provided in addition to the static spreadsheet 1 and can be simulated by rewriting the design specifications of the beam through-holes. And results that can be used by steelworkers and equipment vendors for reinforcing metal fittings that are different from the reinforcing metal fittings provided by the component manufacturer in the static spreadsheet 1 for the specifications of beam through-holes It is.

  Generation of the static spreadsheet 1 will be described below with reference to FIG. The static spreadsheet 1 uses design information such as drawing data created by application software such as CAD provided by the general contractor when “request for start of study” is provided. (1) Picking up drawings (dimension data) And (2) editing information (other than dimension data), (3) calculation, and (4) creating a study document (completion of the static spreadsheet 1).

  In (1), after “steel beam data extraction / input” is executed, “through-hole data extraction / input” is executed. The items handled in “Steel beam data extraction / input” are “beam number (floor number, examination number, beam section name, street, between)”, beam length (span column surface to column surface; pair of columns spanning the beam) Length from column surface to column surface), load bearing width (distance between the core of the beam to be considered and the core of the adjacent parallel beam ÷ 2; add up if the adjacent beam is on both sides), long-term load ( Cell not shown) ”.

  The items handled in “Extract and input through-hole data” are “position information of through-holes (through-hole position column surface to core; distance from column surface, distance between through-holes (through-hole relative position; The case of forming a plurality of through holes), the diameter of the through hole, and the amount of eccentricity (distance from the flange on the beam).

  These items are automatically read into the static spreadsheet 1 as macros in cooperation with application software such as CAD provided by a general contractor. In addition, when the “through hole data extraction / input” is executed, the specification (product specification) of the reinforcing metal fitting corresponding to the beam through hole is automatically input (see π in FIGS. 1 and 2).

  In (2), “selection of steel beam information” is executed. The items handled in “selection of steel beam information” are “beam size (beam list), steel type (F type; material strength), and joining method of both ends of the beam (type of beam: fixing / pin, etc.)”. These are standard steel beam data, and are automatically read into the static spreadsheet 1 as a macro from a database prepared for the steel beam.

  In (3), the range in which the through hole can be formed in the steel beam is calculated. This formable range is a range in which the stress generated in the steel beam falls within the allowable stress value when a long-term load is applied to the steel beam in which the through hole is formed using a known calculation formula (design formula). For example, when the through-hole diameter is changed, calculation on the static spreadsheet 1 is performed with a setting in which the formable range changes.

  The calculation results are output and displayed on the static spreadsheet 1 as “eccentric range (distance from the upper flange)” and “installable range (distance from the left and right column surfaces)”.

  In (4), after executing “determination of whether or not to attach the reinforcing bracket at each examination location”, “determination result (examination document) output” is executed. The judgment results are “Position judgment (position in the length direction of steel beam)”, “Eccentricity judgment (height position from the upper flange)”, and “Communication hole judgment (distance to other through holes adjacent to)” Is output and displayed.

  At this time, the reinforcement fittings that match the input values of (1) and (2) are read out in a macro from the reinforcement fitting database created for all the reinforcement fittings that can be provided by the component manufacturer. The reinforcing bracket has conditions for usable beam size, steel type, and through hole, and those satisfying the conditions are read out. Then, the “attachability determination” is performed based on whether or not the “position information of the through hole” at each examination location is within the calculated eccentricity possible range or installation possible range.

  In the static spreadsheet 1, the items handled in “Steel beam data extraction / input” in (1) above are read and displayed in the fixed value drawing data input section as drawing fixed values of the steel beam drawing data read from the drawings. (See α in FIG. 1). The items handled in the “through-hole data extraction / input” of (1) above are read and displayed in the fixed value design data input unit as design fixed values of the beam through holes (see β in FIG. 1).

  In “Calculation” in (3) above, in order to examine the reinforcing metal fittings suitable for the beam through-holes, calculation is performed from the drawing fixed value and the design fixed value, and the formable range of the beam through-hole is obtained and displayed. (See γ in FIG. 1).

  In (4) “Consultation document preparation” above, it fits the calculated range of beam through-holes, which is not shown in the figure, from a reinforcing bracket database that organizes data of all reinforcing brackets that can be provided by component manufacturers. One of the reinforcing brackets is read out, and the determination result of whether or not the read-out reinforcing bracket can be attached to the steel beam is output and displayed on the determination result output unit (see θ in FIG. 1).

  The static spreadsheet 1 is set in an edit lock state, and is a fixed value drawing data input unit (α), a fixed value design data input unit (β), a calculation result display unit (γ), and a determination result output unit (θ). For all of the above, rewriting is prohibited and provided in the same state as a so-called hard copy.

  In the static spreadsheet 1 created by selecting a reinforcing bracket that can be provided from a component manufacturer based on drawing data of a steel beam provided by a general contractor and design data of a beam through hole, etc., a determination result output unit (θ) In addition, not only “appropriate (OK)” but also the reinforcing bracket determined as “unsuitable (NG)” can be output.

  In the figure, “NG (+8)” in the item “Position Judgment” indicates that it is necessary to move the beam through-hole position to the right end +8 mm to the right, and “NG” in the item “Eccentricity Judgment” "(6)" indicates that it is necessary to decenter 6 mm downward from the upper flange. In this way, when the determination result of “unsuitable” is included, in FIG. 1, (5) by submitting the editing tool, the dynamic spreadsheet 2 that is the editing tool is output as a review tool (data sheet) from the parts manufacturer. And provided to steelworkers and equipment suppliers for use.

  The output display form in the dynamic spreadsheet 2 is the same as that in the static spreadsheet 1. The dynamic spreadsheet 2 replaces the fixed value design data input unit (β) of the static spreadsheet 1 with the variable value design data input unit (φ), and replaces the determination result output unit (θ) with the determination result update output unit (τ ) Is generated instead.

  That is, the fixed value design data input unit (β), the determination result output unit (θ), and the calculation result display unit (γ) of the static spreadsheet 1 are unlocked so that they can be edited. A variable value design data input unit (φ) inputs and displays a rewritable value, and a determination result update output unit (τ) outputs and displays an updatable result. The fixed value drawing data input part (α) is in the editing locked state, and holds and displays the same value as that of the static spreadsheet 1.

  As a result, the dynamic spreadsheet 2 performs the simulation by replacing the beam through hole with other virtual design data (virtual value) while maintaining the specifications of the steel beam and the beam through hole provided by the general contractor. be able to. Then, the result of the simulation is output and displayed on the determination result update output unit (τ).

  The dynamic spreadsheet 2 and the static spreadsheet 1 are different only in that, in the procedures (1) to (4), a virtual value can be input instead of the design data for the beam through hole.

  In short, in the dynamic spreadsheet 2, the variable value design data input unit (φ) is displayed with the virtual value for simulating the beam through hole being rewritable and displayed, and the determination result update output unit (τ) is fixed to the drawing. Recalculate from the values and virtual values (refer to the calculation result display section (γ)), and read out the simulation reinforcement fittings that fit the beam through-holes from the reinforcement fitting database in a macro. The determination result of whether or not it can be attached to is output and displayed in an updatable manner.

  Steelworkers and equipment suppliers conduct a simulation of beam through-holes for dynamic spreadsheet 2 provided once by a component manufacturer, and examine beam through-holes that can give a “OK” judgment result. To do.

  The determination result is the item “extraction / input of through-hole data” in (2) above, that is, “position information of through-hole (through-hole position column surface to hole core; distance from column surface, distance between through-holes (through Relative position of the hole (when multiple through holes are formed in the beam to be examined), diameter of the through hole, and eccentricity (distance from the flange on the beam) ”will be changed. For all steel beams If the determination result “OK” is obtained, the examination result is reported to the general contractor, and the general contractor orders the reinforcing bracket from the general contractor.

  In the beam through hole reinforcement design support system according to the present embodiment described above, the beam through hole and the ring attached to the beam through hole based on the steel beam specifications and the beam through hole design data provided by the general contractor. Static spreadsheet 1 that outputs and displays the suitability of the shape reinforcement brackets, and variable values that can be input and displayed by rewriting the design data of beam through-holes into virtual values based on this static spreadsheet 1 Recalculate from the design data input part (φ) and the fixed and virtual values in the drawing, and read any simulation reinforcement fitting that fits the beam through-hole from the reinforcement fitting database. By providing a dynamic spreadsheet 2 having a determination result update output unit (τ) that outputs and displays the determination result of whether or not it can be attached to the static display. Of course, there are cases where there is an “inappropriate” result in the sheet 1, and even if there is no “inappropriate” result, by using these two spreadsheets 1 and 2 provided by the component manufacturer, It is possible to efficiently study the reinforcing metal fittings made between parts manufacturers, steel frame processors, and equipment companies with a gap between them, and design work can be done rationally and in a short time to achieve labor saving.
