EMBODIMENT OF THE INVENTION Below, the form for implementing this invention will be exemplarily described in detail with reference to drawings. However, the configuration, numerical values, process flow, functional elements, etc. described in the following embodiments are merely examples, and modifications and changes may be made freely, and the technical scope of the present invention is limited to the following description. It is not intended to do so.

[First embodiment]
A concrete placement management device 100 as a first embodiment of the present invention will be explained using FIGS. 1A to 5. The concrete placement management device 100 is a device that divides a structure into small blocks of a predetermined size according to the concrete placement plan, creates a concrete placement plan, etc., and manages efficient concrete placement. be.

Normally, when pouring concrete for a structure, uncured concrete is transported using an agitator vehicle (concrete transport vehicle), and, for example, the uncured concrete is placed one by one into formwork assembled in the construction area on a single day. Type in. Then, before the previously poured concrete hardens, the next concrete is poured and the concrete is stirred using a vibrator or the like to integrate both the poured concrete and the piled concrete. By repeating this work from pouring to integration, concrete pouring in the construction area is completed. After pouring concrete, the poured concrete is cured for a certain period of time to harden, and the assembled formwork is removed from the mold.

In this case, for example, when pouring concrete for a structure like the one shown in Figure 1A, when pouring concrete one after another, before the previously poured concrete hardens, it may overlap with the piled concrete. It is necessary to integrate the layered concrete using a vibrator or the like. At this time, if the concrete pouring time exceeds the control time (for example, the control time according to the concrete standard specifications), cold joints may occur at the concrete pouring joints, which may become weak parts. Therefore, when pouring concrete for structures, it is important to manage the time from mixing the materials, the order of concrete pouring, and the time required to pour concrete.

Here, as the scale of the concrete construction area increases, a large amount of concrete is required, and the number of agitator vehicles required to transport the concrete increases. Furthermore, in order to pour concrete for a large-scale structure, it is necessary to divide the structure into multiple layers depending on the amount that an agitator vehicle can transport, etc., and pour concrete in an orderly manner. The number of layers is also increasing. As a result, there will be many joints, so in order to prevent weak points such as cold joints 150 from occurring, the pouring order and pouring layer thickness must be decided upon, taking into account the concrete pouring time, etc. It was necessary to draw up a 160-meter shot plan.

However, in order to create a concrete pouring plan 160, the work of dividing the structure into several layers or into small blocks of a predetermined size is performed on-site using a two-dimensional design drawing of the structure. This was done manually by field workers. Therefore, it is often difficult to create a precise pouring plan by dividing layers or small blocks, which places a burden on field workers. Therefore, by using the concrete placement management device 100, the user can easily set layer division, small block division, and placement order of each small block.

Next, management of pouring plans using the concrete pouring management device 100 will be explained with reference to FIGS. 1B to 1E. First, as shown in FIG. 1B, 3D design information 120 including 3D data of a structure designed using 3D CAD (Computer-Aided Design) or the like is connected to the concrete placement management device 100. The information is displayed on a display 140 of a monitor or display, a mobile terminal such as a tablet or a smartphone owned by the user, or the like. Note that the three-dimensional design information 120 also includes information such as the construction area and construction period, for example. Further, the three-dimensional design information 120 is created in advance using three-dimensional CAD or the like.

The three-dimensional design information 120 is a construction area set according to the amount of concrete that can be placed in a predetermined period, and is divided into a plurality of medium blocks 123, 124, 125, and 126. For example, focusing on the medium block 123, consider a case where the medium block 123 is divided into small blocks of a predetermined size.

First, as shown in FIG. 1B, the user specifies a division reference point 121 that serves as a reference for division into small blocks in a medium block 123 (target medium block) to be divided into small blocks. Then, the concrete placement management device 100 sets the division reference point 121 at the position specified by the user. Here, the division reference point 121 is a point that serves as a reference for dividing the middle block 123 in which direction based on which position.

In the example shown in FIG. 1B, the division reference point 121 is set at the apex portion (lower left of the bottom surface) of the middle block 123. Note that the division reference point 121 can be set at areas other than the vertices; for example, it can be set at the edge between the vertices, at any position on the side (surface), or at any position on the middle block 123. It can be set at any internal position. The user can set the division reference point for the other medium blocks 124, 125, and 126 by performing the same operation as for the medium block 123.

Next, as shown in FIG. 1C, the axis line is set. That is, considering the division reference point 121 as the origin, the concrete placement management device 100 sets the end point 122 in the X-axis direction at the position specified by the user. Then, the concrete placement management device 100 generates an X-axis 127 as a line segment passing through the end point 122 from the division reference point 121. The generated axis (X-axis 127) may be displayed, for example, beside the middle block 123 or at a position away from the three-dimensional design information 120, as shown in the figure.

Similarly, regarding the Y-axis and the Z-axis, based on the position of the end point of each axis specified by the user, the concrete placement management device 100 calculates a line segment passing through each specified end point from the division reference point 121. , generate the Y-axis and Z-axis. Each of the generated axes (Y-axis, Z-axis) may be displayed next to the middle block 123 or at a position away from the three-dimensional design information 120. Each axis (X-axis 127, Y-axis, Z-axis) is a line segment parallel to the vertical, horizontal, and height directions of the middle block 123.

Next, as shown in FIG. 1D, the user sets parameters necessary for dividing the three-dimensional design information 120 into small blocks of a predetermined size. The parameters set by the user include, for example, equal width division (interval between divisions), equal division (number of divisions and rounding width), layer thickness, and the like. These parameters are set, for example, by inputting numerical values into predetermined boxes in a parameter setting window displayed on the right side of the display 140.

Here, equal-width division refers to the case where a structure is divided at a predetermined width (predetermined division interval) to obtain small blocks of a predetermined size. In this case, for example, dividing lines for the structure are generated and displayed at intervals of 800 mm from the dividing reference point 121 (see FIG. 1D).

Furthermore, equal division refers to a case where a structure is divided so that a predetermined number of divided small blocks are generated. The rounding width determines, for example, the unit of size of each small block generated by division when dividing into equal parts. For example, if the rounding width is set to 100 mm, the size unit (unit of length of one side) of the generated small block is 600 mm, 700 mm, 800 mm, etc. in 100 mm increments. will be generated. Similarly, for example, if the rounding width is set to 10 mm, the size unit (unit of length of one side) of the generated block will be small, such as 810 mm, 820 mm, 830 mm, etc., in 10 mm increments. Blocks will now be generated.

In this way, by setting the rounding width and adjusting the fraction of the size of the small blocks, it becomes easier to manage the volume of each small block, and therefore it becomes easier to manage concrete placement. Then, the concrete placement management device 100 divides the three-dimensional design information 120 into small blocks of a predetermined size according to the set parameters. Once the concrete is divided into small blocks of a predetermined size, concrete placement can be appropriately managed by setting the order of concrete placement for each of the small blocks. The setting of the pouring order is performed for each layer, for example, but is not limited to this.

As shown in FIG. 1E, when the structure as a whole includes structures having a plurality of different shapes, for example, by setting a division reference point for each structure, the structure can be The whole is divided into small blocks. Note that when a single structure is considered to have a complex shape, it can be considered as a combination of structures having a plurality of different shapes.

When the structure as a whole includes structures having multiple different shapes, the connecting parts of each structure are located at positions where cross-sectional changes are discontinuous when looking at the structure as a whole from the Z-axis direction. It is a surface with a certain cross-sectional change.

When such a cross-sectional change surface exists, for example, if the structure is divided based on one division reference point 131, concrete will be poured continuously in the part that straddles the cross-section change surface, The cross-sectional change surface becomes a weak part. Therefore, it is necessary to set boundaries and manage this cross-sectional change surface. Therefore, it is necessary to set the division reference point 131 every time a cross-sectional change surface appears. For example, when concrete is poured across a surface with a change in cross section, moisture rises (bleeding) from the uncured concrete, and the bleeding may concentrate on the surface with a change in cross section, resulting in a weak spot. Therefore, when a cross-sectional change surface exists, it is preferable to set the division reference point 131 so that the cross-section change surface becomes a boundary surface. In this way, by setting the division reference point 131 on the cross-sectional change surface (by using the cross-section change surface as the boundary surface), it is possible to suppress the generation of small blocks that straddle the cross-section change surface.

As described above, the user sets a plurality of division reference points 131 in the three-dimensional design information 120, and sets parameters such as the division width and the number of divisions for each of the set division reference points 131. Then, the concrete placement management device 100 divides the structure into small blocks of a predetermined size based on the set division reference points 131 and parameters.

As described above, in the concrete placement management device 100, a concrete placement plan is created in units of small blocks. Then, at the concrete pouring site, concrete is poured according to the drafted pouring plan (three-dimensional design information 120).

However, while concrete is being poured in accordance with the three-dimensional design information 120, the arrangement plan for agitator vehicles for transporting fresh concrete may not proceed as planned due to, for example, traffic conditions. In this case, since concrete placement has already started, if concrete is not placed immediately in the layer where concrete is currently being placed, the concrete that has already been placed will begin to harden. This may cause weak parts such as cold joints.

Therefore, as a way to secure time until the agitator vehicle arrives at the site, we piled up the concrete so that the thickness of the entire small block was thinner than originally planned, and in this state, we temporarily stopped pouring concrete. Stop and wait for the next agitator vehicle to arrive. When the agitator truck arrives, the best way to prevent cold joints is to cancel the temporary suspension of concrete pouring and restart concrete pouring. In this case, we have taken as an example a case where the dispatch of an agitator vehicle is delayed, but this is not limited to, for example, construction may be continued due to unforeseen circumstances such as a failure of a pump truck or a sudden change in weather. For example, when it is difficult to

However, such a countermeasure is one of the emergency evacuation countermeasures that are not included in the pouring plan, and is often carried out at the discretion of the on-site worker. Therefore, there is often no way to record such countermeasures, and in many cases they are not recorded.

On the other hand, if concrete placement is temporarily stopped, it would be possible to keep a record of that fact, which would be useful for later verification and for repairs when weak parts such as cold joints occur in the structure. This is useful as reference information when considering reinforcement. In other words, one of the advantages of keeping such a record is that it becomes possible to quickly and easily identify the fact that a pause occurred.

Here, referring to FIG. 1F, there is shown a form 170 in which concrete pouring time and the like are recorded for each small block. The form 170 is provided with a notes column 171, and for example, <12:53 to 13:38 temporary stop> is recorded in the notes column 171 of number 21. This indicates that concrete placement has been suspended for the numbered block number 21 for the time recorded here. Similarly, in the notes column 171 of number 39, <15:54 to 16:01 temporary stop> is recorded. This also indicates that concrete placement was suspended for the time recorded here for the small block numbered 39. Note that the form 170 is data that records information such as when concrete was placed for each small block, and it is possible to record information other than the timing of concrete placement. Here, only the timing is shown.

In this way, the concrete placement management device 100 measures and records the concrete placement time, and also measures and records the temporary stop time when concrete placement is temporarily stopped. There is.

That is, in the time measurement by the concrete placement management device 100, since concrete placement has already started for the predetermined small book, the time measurement of the elapsed time from the start of concrete placement for the predetermined small block is not stopped. However, the concrete placement management device 100 measures the time during which concrete placement is temporarily stopped, as well as the elapsed time from the start of concrete placement.

Here, the recording of the temporary stop time will be specifically explained using the small block of the form 170 shown in FIG. 1F with the block number A21 as an example. As shown in the figure, concrete pouring for A21 was performed from 12:51 to 13:46, but the concrete pouring was temporarily stopped from 12:53 to 13:38. Here, if it is necessary to temporarily stop pouring concrete, the worker pours concrete into the small block A21 thinner than the thickness of the small block before the temporary stop.

In other words, by thinly covering the interface between the small block A21 and the small block A12 with concrete, a temporary stop is made to allow time for overlapping. In other words, if concrete is not poured into the next small block A21 within a predetermined time after the pouring of the small block A12 is completed, the concrete poured into A12 will solidify and the concrete between A12 and A21 will be hardened. Cold joints will occur at the interface between the two. Therefore, when concrete pouring is to be temporarily stopped, time for the temporary stop must be created by pouring concrete thinner than the thickness of the small blocks.

In the example shown in FIG. 1F, first, a thin layer of concrete is poured into the small block A21 between 12:51 and 12:53. Thereafter, the worker operates a tablet terminal or the like to record that concrete pouring in the small block of A21 will be temporarily stopped from 12:53 to 13:38. When the temporary stop time ends, the worker operates a tablet terminal, etc. to restart concrete pouring at 1:38 p.m., pours the remaining concrete in this block, and finishes pouring at 1:46 p.m. Record that it has been completed. Through such work, the temporary stop time is recorded in the form 170, and it is possible to confirm data indicating that the typing (overprinting) has been properly performed.

Therefore, according to the concrete placement management device 100, in order to avoid an emergency situation, it is possible to notify not only the site workers but also the verification staff after the completion of concrete placement that there has been a temporary stoppage of concrete placement. It is now possible to check. In addition, in the concrete placement management device 100, even if an emergency situation occurs, the start time and end time of the temporary stop are recorded in the form 170, so that repairs or reinforcement of the structure are not necessary. Even if something goes wrong, it is advantageous because it allows you to quickly identify areas that should be repaired or reinforced.

Next, with reference to FIG. 2, the configuration of the concrete placement management device 100 will be described. The concrete placement management device 100 includes an acquisition section 201 , a temporary stop start signal reception section 202 , an elapsed time measurement section 203 , and a release signal reception section 204 .

The acquisition unit 201 divides the three-dimensional design information 120 into medium blocks of a predetermined size, and divides the three-dimensional design information 120 into medium blocks of a predetermined size. Three-dimensional design information 120 having divided data divided into small blocks is obtained. The three-dimensional design information 120 is divided into medium blocks of a predetermined size. Then, each of the divided medium blocks is divided into small blocks of a predetermined size for each pouring layer of a predetermined thickness that is separated by a plane perpendicular to a predetermined direction of the medium block. The three-dimensional design information 120 includes divided data.

When the three-dimensional design information 120 is generated by a device different from the concrete placement management device 100, the acquisition unit 201 acquires the three-dimensional design information 120 from the device through a wired connection or a wireless connection. Further, the acquisition unit 201 may acquire the three-dimensional design information 120 via a recording medium on which the three-dimensional design information 120 is recorded.

The pause start signal receiving unit 202 receives a pause start signal indicating the start of a pause in concrete placement. In other words, while concrete is being poured according to the three-dimensional design information 120, it becomes impossible to perform concrete pouring according to the three-dimensional design information 120 in the pouring layer to which a predetermined small block among the small blocks belongs. There is. In this case, the concrete placement management device 100 can also determine that the placement layer to which the predetermined small block to which concrete can no longer be placed belongs is the placement layer where concrete is being placed.

Then, if the pouring layer to which the predetermined small block belongs is a pouring layer in which concrete is being poured, the pause start signal receiving unit 202 receives a pause start signal indicating the start of a pause in concrete pouring. . The reason for determining whether or not the pouring layer to which a given small block belongs is a pouring layer in which concrete is being poured is that if it is not a pouring layer in which concrete is being poured, concrete is not being poured. This is because there is no need to temporarily stop concrete pouring. However, if concrete placement is not in progress, there is no need to temporarily stop concrete placement, so the concrete placement management device 100 does not need to make the determination.

The signal indicating the start of a temporary stop is transmitted, for example, by operating a temporary stop button displayed on the display of a mobile terminal such as a tablet terminal owned by a worker at the site. Then, the pause start signal receiving section 202 receives the transmitted pause start signal. Note that the pause start signal receiving unit 202 receives the pause start signal through wired communication or wireless communication.

First, when concrete pouring for a predetermined small block is started, the elapsed time measuring unit 203 starts measuring the elapsed time from the start of concrete pouring for the predetermined small block. For example, when the on-site worker operates the time measurement start button displayed on the display of a mobile terminal such as a tablet terminal, the elapsed time clock unit 203 starts measuring the elapsed time. do. When concrete pouring for the predetermined block is completed, a worker at the site operates a pouring completion button displayed on the display of the tablet terminal, and the elapsed time clock unit 203 measures the elapsed time. The timing ends.

When the pause start signal reception unit 202 receives the pause start signal, the elapsed time clock unit 203 measures the elapsed time from the start of concrete placement for the predetermined small block, and Time the pause time from stop. Here, when the temporary stop start signal receiving section 202 receives the temporary stop start signal, the elapsed time measuring section 203 measures the elapsed time from the start of concrete pouring for a predetermined small block, and starts concrete pouring. Measures the pause time.

In this manner, the elapsed time measuring section 203 measures the temporary stop time without stopping the elapsed time from the start of concrete pouring for a predetermined small block. This allows the concrete placement management device 100 to record that concrete placement has been temporarily stopped while concrete is being placed for a predetermined small block.

The release signal receiving unit 204 receives a release signal indicating the end of the temporary suspension of concrete placement. Then, when the elapsed time clock unit 203 receives the release signal, it stops counting the pause time. When the temporary suspension time for concrete pouring has ended and concrete pouring is ready to resume, the worker at the site can, for example, press the pause release button displayed on the display of a tablet terminal, and a release signal is activated. is now being sent.

The elapsed time clock unit 203 stops counting the pause time when the release signal receiving unit 204 receives the release signal. Continue to measure the elapsed time from the start of concrete pouring. Note that concrete placement may be temporarily stopped multiple times in the same predetermined small block.

As described above, in the concrete placement management device 100, the timing of the concrete placement pause time is started and stopped at the timing when the pause start signal and the pause release signal are received, respectively.

FIG. 3 is a diagram for explaining an example of the small block table 301 included in the concrete placement management device 100. The small block table 301 stores a planned pouring time 312 in association with a small block number 311. The small block number 311 is an identifier for identifying a small block included in the three-dimensional design information 120. The planned pouring time 312 is the pouring time for each small block at the planning stage. The concrete placement management device 100 then refers to the small block table 301 to manage concrete placement.

The hardware configuration of the concrete placement management device 100 will be described with reference to FIG. 4. A CPU (Central Processing Unit) 410 is a processor for arithmetic control, and realizes each functional configuration of the concrete placement management device 100 shown in FIG. 2 by executing a program. The CPU 410 has multiple processors and may execute different programs, modules, tasks, threads, etc. in parallel. ROM (Read Only Memory) 420 stores fixed data such as initial data and programs, and other programs. Further, the network interface 430 communicates with other devices via a network. Note that the number of CPUs 410 is not limited to one, and may be a plurality of CPUs or may include a GPU (Graphics Processing Unit) for image processing. Further, it is preferable that the network interface 430 has a CPU independent of the CPU 410 and writes or reads transmitted and received data in a RAM (Random Access Memory) 440 area. Further, it is desirable to provide a DMAC (Direct Memory Access Controller) that transfers data between the RAM 440 and the storage 450 (not shown). Further, the CPU 410 recognizes that data has been received or transferred to the RAM 440 and processes the data. Further, the CPU 410 prepares the processing results in the RAM 440 and leaves subsequent transmission or transfer to the network interface 430 or DMAC.

The RAM 440 is a random access memory used by the CPU 410 as a temporary storage work area. A storage area is secured in the RAM 440 to store data necessary for realizing this embodiment. The three-dimensional design information data 441 is data including three-dimensional CAD data of a structure to be concreted. Planned pouring time data 442 is data on the start time and end time of concrete pouring planned for each small block. The elapsed time data 443 is data about the elapsed time measured from the start of concrete placement for each small block. The temporary stop time data 444 is data on the temporary stop time that is measured when a temporary stop occurs during pouring of concrete in a predetermined small block.

Transmission/reception data 445 is data transmitted/received via network interface 430. The RAM 440 also has an application execution area 446 for executing various application modules.

The storage 450 stores a database, various parameters, and the following data or programs necessary for realizing this embodiment. Storage 450 stores small block table 301. The small block table 301 is a table that manages the relationship between the small block number 311 and the planned pouring time 312 shown in FIG.

The storage 450 further stores an acquisition module 451, a pause start signal reception module 452, an elapsed time measurement module 453, and a cancellation signal reception module 454. The acquisition module 451 is a module that acquires the three-dimensional design information 120 of a structure, which includes divided data obtained by dividing the three-dimensional design information 120 into small blocks of a predetermined size. The pause start signal receiving module 452 is a module that receives a pause start signal. The elapsed time timing module 453 is a module that measures the elapsed time from the start of concrete placement for each small block. The release signal receiving module 454 is a module that receives a release signal indicating the end of the temporary suspension of concrete placement. These modules 451 to 454 are read into the application execution area 446 of the RAM 440 by the CPU 410 and executed. The control program 455 is a program for controlling the entire concrete placement management device 100.

The input/output interface 460 interfaces input/output data with input/output equipment. A display section 461 and an operation section 462 are connected to the input/output interface 460. Further, a storage medium 464 may be further connected to the input/output interface 460. Furthermore, a speaker 463 as an audio output section, a microphone (not shown) as an audio input section, or a GPS position determination section may be connected.

In step S511, the release signal receiving unit 204 determines whether or not a release signal indicating the end of the temporary suspension of concrete placement has been received. If it is determined that the release signal has not been received (NO in step S511), the concrete placement management device 100 returns to step S509. If it is determined that the release signal has been received (YES in step S511), the concrete placement management device 100 proceeds to the next step.

In step S513, the elapsed time clock unit 203 ends counting the pause time. In step S515, the concrete placement management device 100 determines whether to end the management of concrete placement for the structure. If it is determined that the concrete placement management is not to be ended (NO in step S515), the concrete placement management device 100 returns to step S505. If it is determined that the concrete placement management is to be ended (YES in step S515), the concrete placement management device 100 ends the process.

According to this embodiment, it is possible to deal with troubles that occur during concrete pouring. During concrete pouring, if concrete cannot be supplied according to the pouring plan, the time during which pouring is temporarily stopped can be measured and recorded, so it can be used in case a problem occurs with the concrete after construction. This information can be used as post-event verification information or as reference information when carrying out repairs, reinforcement, etc.

In addition, if there is a temporary stop in concrete pouring for a predetermined small block, the elapsed time from the start of concrete pouring for the predetermined small block and the temporary stop time are measured and recorded, so in case of an emergency You can keep track of your history while dealing with this issue. Furthermore, even if an emergency situation such as a delay in concrete supply occurs, a smaller amount of concrete than planned will be placed in a given small block, and the supply will be resumed and the unconcrete portion of that small block will be replaced. Since it is possible to gain more time for repeated pouring, the influence on the overall pouring plan can be minimized.

[Second embodiment]
Next, a concrete placement management device 600 according to a second embodiment of the present invention will be explained using FIGS. 6 to 9. FIG. 6 is a block diagram for explaining the configuration of a concrete placement management device 600 according to this embodiment. The concrete placement management device 600 according to this embodiment differs from the first embodiment in that it includes a temporary stop time determination section and a notification section.

The concrete placement management device 600 includes a temporary stop time determination section 601 and a notification section 602. The pause time determination unit 601 determines whether the pause time measured by the elapsed time clock unit 203 exceeds a predetermined pause time. In other words, in the concrete placement management device 600, when it becomes necessary to temporarily stop concrete placement while concrete is being placed in a predetermined small block, the time during which concrete placement is temporarily stopped is determined. Can be timed. However, concrete has the property of hardening after a predetermined period of time has elapsed from the start of pouring, and concrete pouring cannot be suspended indefinitely.

Therefore, the temporary stop time determination unit 601 determines the amount of time during which a smaller amount of concrete is poured than the planned amount of concrete to be poured to ensure time for repeating until the emergency situation is resolved. It is determined whether the (temporary stop time) exceeds the concrete hardening time (predetermined pause time). Here, the predetermined temporary stop time is a reference time (warning reference time) for determining whether or not to issue a warning. Further, a plurality of predetermined temporary stop times may be provided depending on the properties of concrete, pouring plan, agitator vehicle allocation plan, and the like.

Then, the notification unit 602 notifies a predetermined warning when the temporary stop time determining unit 601 determines that the temporary stop time for concrete pouring exceeds the predetermined temporary stop time. The warning notified by the notification unit 602 is, for example, sound, vibration, light, or the like. The notification unit 602 notifies the operator of a warning by, for example, outputting sound from a speaker of a mobile terminal such as a tablet owned by the worker, vibrating the tablet, or lighting up the display of the tablet. Note that the warning notification method is not limited to the method shown here.

The small block table 701 stores a temporary stop time 711 and a predetermined temporary stop time 712 in association with the small block number 311. The temporary stop time 711 is the time during which concrete placement is temporarily stopped, and is the time measured by the elapsed time measuring section 203. The predetermined pause time 712 is a time (warning reference time) that the pause time determination unit 601 compares with the pause time measured by the elapsed time clock unit 203. When the pause time exceeds the predetermined pause time 712, the notification unit 602 issues a certain warning. Note that a plurality of predetermined temporary stop times 712 may be set depending on the properties of concrete, the agitator vehicle allocation plan, and the like.
