Description

The present invention relates to a mobile object monitoring system for monitoring a mobile object moving along a rail, and a roof construction method using the mobile object monitoring system.

For example, a slide construction method as disclosed in Japanese Patent Application Laid-Open No. 2002-200313 is sometimes adopted as a method for constructing a roof of a large space structure such as a gymnasium or a factory.

In Patent Literature 1, a scaffolding is assembled in the vicinity of a gable wall portion on one side of a building frame constructed in advance, and the scaffolding is used to assemble one unit of a steel frame truss that constitutes a roof. Next, the assembled steel frame truss is slid by one unit width toward the end wall on the other side along a pair of rails extending in the girder direction provided on the frame. After that, the same scaffolding will be used to assemble one unit of the following steel frame truss. This is added to the preceding steel frame unit, and similarly slid by one unit width along a pair of rails toward the end wall portion on the other side. By repeating this work, a steel-framed roof is constructed on the frame.

According to the construction method described above, all of the plurality of steel frame trusses can be assembled on scaffolding provided near the end wall portion on one side of the building frame. As a result, it is possible to assemble the steel frame units in a small space, and in parallel with the construction method of the steel frame roof, it is also possible to use the space inside the frame to carry out work on the lower part of the roof at the same time. .

JP-A-53-130813

In the slide construction method such as that disclosed in Patent Document 1, generally, the amount of movement (moving speed) is continuously measured while the steel truss is slid, and the slide device is automatically controlled so that the amount of movement is uniform on the pair of rails. However, in many cases, the "positional deviation" of the steel frame truss in the direction orthogonal to the rail is detected visually by the observer.

For this reason, in roof construction using the slide construction method, it is necessary to increase the number of on-site workers for the convenience of deploying observers. In the centralized control room that controls the slide device, there are various problems in terms of workability, quality, safety, etc., such as not being able to grasp the above-mentioned "positional deviation" that occurred in the steel frame truss until receiving a contact from the observer. had In addition, the steel frame unit supported by a pair of rails repeats expansion and contraction in the direction perpendicular to the progress due to temperature changes, but there is no established means for grasping the amount of expansion and contraction caused by such a phenomenon.

It was made in view of such problems, and its main purpose is to manage the displacement of a moving body moving on a rail in real time.

In order to achieve such an object, the mobile object monitoring system of the present invention is a mobile object monitoring system for monitoring a mobile object moving along a rail, comprising: a displacement detection device for detecting displacement of the mobile object; a side distance measuring device provided at least on the front side and the rear side of the body in the traveling direction and measuring the separation distance from the rail in the direction perpendicular to the traveling direction, wherein the displacement detection device is obtained by the side distance measuring device and a horizontal displacement detector for detecting a horizontal displacement of the moving body in a direction perpendicular to the movement of the rail with respect to the rail based on the measured value.

In the mobile object monitoring system of the present invention, the side distance measuring devices are arranged in pairs in a direction perpendicular to the movement, and the displacement detection device measures the displacement using the paired side distance measuring devices. It is characterized by comprising an expansion/contraction amount detection unit that calculates an expansion/contraction amount of the moving body in the direction perpendicular to the movement thereof based on actual measurement values.

The moving body monitoring system of the present invention is characterized in that the moving body is a block obtained by dividing a roof skeleton that slides along rails provided on the lower structure in the traveling direction.

The roof construction method of the present invention is a roof construction method using the mobile object monitoring system of the present invention, wherein the blocks constituting the roof skeleton are monitored by the mobile object monitoring system, and the rails are attached to the blocks. It is characterized by sliding along.

According to the moving body monitoring system and the roof construction method of the present invention, the side distance measuring device measures the separation distance in the direction orthogonal to the rail on the front side and the rear side in the moving direction of the moving body moving on the rail. set up. As a result, it becomes possible to manage the horizontal displacement in the direction perpendicular to the movement of the moving object in real time.

In addition, if the side distance measuring instruments provided at least on the front side and the rear side of the traveling direction of the moving body are arranged in pairs with an interval in the direction perpendicular to the traveling direction, the amount of expansion and contraction of the moving body moving on the rail in the direction perpendicular to the traveling direction can be measured. can be measured at least at two points, the front side and the rear side. This makes it possible to grasp in real time the state in which the moving object expands or contracts in the direction perpendicular to its movement due to temperature changes.

If the mobile object monitoring system described above is adopted for roof construction using the slide construction method, the mobile object monitoring system can constantly monitor the blocks that make up the roof frame that slides on the rails provided on the substructure. As a result, it is possible to omit the task of assigning a watchman to monitor the behavior of the blocks, and it is possible to save manpower and labor.

In addition, the centralized control room that controls the slide device that moves the blocks should always be aware of the horizontal displacement in the direction perpendicular to the movement of the blocks that are sliding, and if an abnormality is confirmed, it should be dealt with promptly. is also possible.

Furthermore, it is also possible to grasp in real time the amount of expansion or contraction of the block that expands or contracts in the direction perpendicular to the progress due to temperature changes, and it is also possible to reflect this information in the construction work.

According to the present invention, a moving body that moves on the rail is moved on the rail by providing side distance measuring instruments for measuring the separation distance in the direction orthogonal to the rail on the front side and the rear side in the moving direction of the moving body that moves on the rail. It becomes possible to manage the displacement occurring in the moving body with high accuracy and efficiency.

In the present embodiment, a case of adopting a moving body monitoring system for roof construction of a large space structure by the slide construction method will be taken as an example, and the details thereof will be described with reference to FIGS. 1 to 10. FIG.

≪≪Overview of large space structure and slide construction method≫≫
Before explaining the moving body monitoring system, the outline of the large space structure and the outline of the slide construction method adopted for the roof construction of the large space structure will be explained.

≪Outline of large space structure≫
As shown in FIGS. 1(a) and 1(b), the large-space structure 1 is a building in which a pair of parallel walls 2 constituting a lower structure support a roof 5 as an upper structure. , the roof 5 comprises a roof skeleton 3 and a roof finishing material 4 made of a steel truss structure.

The roof finishing material 4 is provided on the roof frame 3, and may be any material as long as it can withstand rainwater, snow, and the like. In this embodiment, the roof finishing material 4 provided on the upper chord member side of the roof frame 3 is taken as an example, but eaves panels provided on the lower chord member side of the roof frame 3 may be used.

The roof frame 3 is provided so as to span the pair of walls 2 and is formed by connecting a plurality of blocks arranged in parallel in the extending direction of the walls 2 . In the plan view of FIG. 1(b), a case where three blocks, a front block 3a, an intermediate block 3b, and a rear block 3c are connected by a connecting steel frame 10, is taken as an example.

As shown in FIG. 1(a), the pair of walls 2 are constructed with a building space S interposed therebetween, and a rising wall 22 is provided along the outside of the walls 2 at the top end thereof. A rail 21 is installed along the extending direction of the wall body 2 in parallel with the rising wall 22 . The rail 21 supports the front block 3a, the intermediate block 3b, and the rear block 3c, and functions as a guide member when they slide in the extending direction of the wall 2. As shown in FIG. It should be noted that the rising wall 22 may not necessarily be provided at the top of the wall 2 .

≪≪Outline of roof construction using the slide construction method≫≫
The above roof 5 can be assembled by adopting a slide construction method. The procedure is roughly as follows.

First, as shown in FIG. 2( a ), a work stage 7 is provided using the building space S on one end side of the pair of walls 2 . The work stage 7 is supported by a plurality of temporary support platforms 8 erected in the building space S. Then, as shown in FIG. 2(b), the front block 3a is assembled on the work stage 7, and the assembled front block 3a is slid along the extending direction of the wall 2. As shown in FIG.

Next, as shown in FIG. 3(a), the intermediate block 3b is assembled on the working stage 7 after the front block 3a has moved. As shown in FIG. 3(b), the assembled intermediate block 3b is connected to the rear end of the front block 3a via a connecting steel frame 10 to construct a unit block 3d. This unit block 3 d is slid along the extending direction of the wall 2 .

By the same procedure, as shown in FIG. 4(a), the rear block 3c is assembled on the work stage 7 after the unit block 3d has been moved, and the unit block 3d is configured as shown in FIG. 4(b). It connects with the rear end of the intermediate block 3b which connects through the connecting steel frame 10, and constructs the roof skeleton 3. After or while building the roof frame 3 in this manner, the roof finishing material 4 is attached, and the construction of the roof 5 is completed.

In roof construction using the slide construction method, the blocks (front block 3a, intermediate block 3b, rear block 3c) that make up the roof frame 3 are all assembled on a work stage 7 provided at one end of the wall 2. . As shown in FIG. 2(a), the work stage 7 can be provided by using a part of the building space S, which is economical, and the remaining space of the building space S can be efficiently used for other work. Available. In addition, since the work performed in the building space S and the assembly work of the roof frame 3 do not interfere with each other in the work area, both works can be carried out in parallel.

In the above procedure, the operation of sliding the front block 3a and the unit block 3d uses the slide support 6, the rail 21 and the slide device 15 as shown in FIGS. Hereinafter, the front block 3a will be taken as an example and the details thereof will be described, but the intermediate block 3b and the rear block 3c also have the same configuration.

<<Slide bearing 6 and rail 21>>
The slide bearing 6 includes a bearing body 61 and a sliding member 62 provided on the lower surface of the bearing body 61, as shown in FIG.

The support bodies 61 are provided on the column bases 32 positioned above the wall body 2 in the front block 3a, respectively, and slip members 62 are attached to the lower surfaces thereof. The sliding member 62 is made of a resin plate or the like, and its lower surface is in contact with the rail upper surface member 2d.

The rail upper surface material 2d is formed by smoothing the upper surface of the rail 21, applying a lubricant, or attaching a stainless steel plate. As described above, the rail 21 having such a rail upper surface member 2d is made up of long members provided at the top ends of the paired walls 2, and FIG. listed in

<<Slide device 15 and central control room>>
Any mechanism may be adopted as the slide device 15 as long as it is a mechanism capable of sliding the front block 3a along the rail 21 in the extending direction of the wall 2 . For example, FIG. 6A exemplifies a mechanism in which the front block 3a is towed by a plurality of synchronized hydraulic jacks 151. As shown in FIG.

A plurality of hydraulic jacks 151 are installed in each bearing main body 61 of the slide bearing 6 provided in the front block 3 a so that the expansion and contraction directions thereof are oriented in the extending direction of the rails 21 . While being extended, one end is connected to the front side of the support body 61 and the other end is detachably attached to the rail 21 .

As a result, as shown in FIG. 6(b), by contracting the hydraulic jack 151, the front block 3a is moved along the pair of rails 21 using the slide bearings 6 in the extending direction of the wall 2. You can slide. The sliding device 15 having such a structure is automatically controlled in a centralized control room so that the movement amount (moving speed) of the front block 3a is uniform on the pair of rails.

By the way, when the slide bearing 6 is used, the front block 3a expands and contracts in the direction perpendicular to the traveling direction (span direction) under the influence of outside temperature and direct sunlight, as shown in FIG. 7(a). Further, as shown in FIG. 7(b), the front block 3a during the sliding movement may be horizontally displaced in the direction perpendicular to the movement, causing a problem in the sliding movement. Such behavior is the same when moving the unit block 3d as shown in FIG. 3(b).

Therefore, in adopting the slide construction method for roof construction, the moving body monitoring system 100 is used to perform sliding movement while constantly monitoring the front block 3a and the unit block 3d, and the amount of expansion and contraction in the direction perpendicular to the progress and horizontal displacement are monitored. Manage in real time along with the amount of directional movement.

<<<Moving Body Monitoring System 100>>>>
Mobile object monitoring system 100, as shown in FIG. Prepare.

<<Lateral distance measuring instrument 110 and cantilever frame 140>>
The side distance measuring device 110 is installed on the front block 3a and measures the separation distance from the rail 21 in the direction perpendicular to the progress. In the present embodiment, a laser distance sensor is used, but a non-contact distance measuring instrument using ultrasonic waves or millimeter waves, a contact distance measuring instrument, or the like can be used to measure the distance from the rail 21 continuously. Any measuring instrument can be used as long as it can measure Such a side distance measuring device 110 may be attached to the front block 3a using any jig, but FIG. 5 exemplifies a case where a cantilever frame 140 is employed.

The cantilever frame 140 is attached to the bearing body 61 of the slide bearing 6 so as to protrude toward the building space S, and the mounting portion 141 of the lateral distance measuring device 110 is provided in the height range of the rail 21. . In FIG. 5, the mounting portion 141 is set so that the side distance measuring device 110 is arranged at a height facing the side surface of the upper flange 21b of the rail 21, but the side distance measuring device 110 is positioned between the web 21c and the web 21c. The mounting portions 141 may be set so as to have heights facing each other.

Further, the cantilever frame 140 is stiffened by diagonal members 142 as necessary to prevent deformation of the mounting portion 141 due to the weight of the side distance measuring device 110 or the like. As a result, the side distance measuring device 110 can always measure the separation distance from the rail 21 with high accuracy.

As shown in FIG. 2(b), such cantilever frames 140 and side distance measuring devices 110 are provided in total four bodies, one pair each at the forward end and the rearward end of the forward block 3a. As a result, it is possible to measure the separation distance from the rail 21 at each of the vicinity of the four corners of the front block 3a.

Incidentally, when the unit block 3d is slid, as shown in FIG. , a pair of side distance measuring devices 110 may be prepared and provided in the intermediate portion of the unit block 3d in the traveling direction. In this way, the separation distance from the rail 21 can be measured at a total of six locations including the vicinity of the four corners of the unit block 3d.

<<Front distance measuring device 120>>
The forward distance measuring device 120 measures the separation distance of the forward block 3a to the movement target point. The forward distance measuring device 120 is similar to the side distance measuring device 110, and may employ either a contact type or non-contact type distance measuring device.

In this embodiment, as shown in FIG. 6(a), a laser distance sensor that emits a laser toward a target T installed near the movement destination point is employed. The combination of the front distance measuring device 120 and the target T is arranged on both corner sides of the front end of the front block 3a in the traveling direction. As a result, the separation distance to the movement destination can be measured at both corners of the forward end of the front block 3a in the traveling direction.

<<Displacement detector 130>>
As shown in FIG. 8, the displacement detection device 130 may be any device that includes an input unit 131, an arithmetic processing unit 132, and an output unit 133, and may be a personal computer, a notebook PC, a tablet terminal, or the like. .

The input unit 131 is wirelessly or wiredly connected to the side distance measuring device 110 and the front distance measuring device 120. The measured value of the distance from the rail 21 obtained by the side distance measuring device 110 and the front distance measuring device Information such as the measured forward distance to the target T acquired in 120 is received. Although not shown, it may be configured to be connected to an input device such as a keyboard, mouse, scanner, etc., and receive information input to these devices.

The output section 133 includes a data output section 1331 and an alarm output section 1332 . The data output unit 1331 outputs information acquired via the input unit 131 , processed data processed by the arithmetic processing unit 132 , and the like to the display device 134 .

Further, the alarm output unit 1332 outputs alarm information to the display device 134 when the horizontal displacement detection unit 1321 of the arithmetic processing unit 132, which will be described later, detects an abnormality in the horizontal displacement of the front block 3a or the unit block 3d.

The display device 134 may be a monitor installed in the centralized control room of the slide device 15 connected to the output unit 133 wirelessly or by wire, a display, a printer, or the like. Further, the alarm information output from the alarm output unit 1332 may be configured not only to be output to the display device 134 but also to be output to an output device such as a speaker capable of giving an audible notification.

Furthermore, the terminal device 135, such as a mobile terminal carried by a worker or a personal computer for management installed in a construction office, and the displacement detection device 130 may be capable of transmitting data to each other via a communication network. In this way, information can be input from the terminal device 135 to the displacement detection device 130 via the input section 131 , or information can be output from the displacement detection device 130 to the terminal device 135 via the output section 133 . In addition. The communication network may be constructed by any of the Internet, a dedicated communication line, and the like.

The arithmetic processing unit 132 includes storage units such as a CPU (Central Processing Unit), ROM (Read Only Memory) and RAM (Random Access Memory), and controls the operation of the displacement detection device 130 . Such an arithmetic processing unit 132 includes at least a horizontal displacement detection unit 1321 , an expansion/contraction amount detection unit 1322 , and a movement amount detection unit 1323 . The details will be described in the construction method of the roof using the mobile object monitoring system 100, but the outline will be described by taking the front block 3a as an example.

The horizontal displacement detection unit 1321 calculates the horizontal displacement of the front block 3a in the direction orthogonal to the rail 21 caused by the slide movement based on the measured distance from the rail 21 obtained by the lateral distance measuring device 110 . Further, based on the calculated horizontal displacement and a preset threshold for determining horizontal displacement, it is determined whether or not there is an abnormality in the horizontal displacement of the front block 3a.

The expansion/contraction amount detection unit 1322 detects the distance between the front end and the rear end of the front block 3a based on the actual measurement value of the distance from the rail 21 obtained by a pair of side distance measuring devices 110 provided at the front end and the rear end of the front block 3a. Then, the amount of expansion and contraction in the direction perpendicular to the progress is calculated. Then, the movement amount detection unit 1323 calculates the amount of movement of the front block 3a in the traveling direction at both corners of the front end based on the front distance measurement value to the target T obtained by the front distance measuring device 120 .

<<<Roof Construction Method Using Mobile Monitoring System 100>>>>
A procedure for constructing a roof by the slide construction method using the mobile object monitoring system 100 having the above configuration will be described below.

<<Assembly of front block 3a>>
First, as shown in FIG. 2(b), the front block 3a is assembled on the working stage 7 provided on one end side of the pair of walls 2 in the building space S. As shown in FIG.

The front block 3a is assembled while being supported by a telescopic device 9 installed at a predetermined position on the working stage 7, as shown in FIG. 9(a), for example. The extension device 9 not only supports the front block 3a, but also controls the amount of extension of each to make it swell. Along with these operations, it is preferable to install the bearing body 61 and the sliding member 62 of the slide bearing 6 on the column base 32 positioned above the rail 21 .

<Preparation for slide movement>
After that, the telescopic device 9 is jacked down to support the assembled front block 3a on the pair of rails 21 as shown in FIG. 9(a).

Before or after this work, as shown in FIG. 5, a front distance measuring device 120 is installed on the front block 3a. Also, the side distance measuring device 110 is installed via the cantilever frame 140 . Further, as shown in FIG. 6(a), a slide device 15 is installed to slide the front block 3a along the rail 21 in the direction in which the wall 2 extends.

≪Setting the initial value and judgment threshold≫
Before the slide movement using the slide device 15 is started, the moving object monitoring system 100 sets the front distance initial value, the separation distance initial value, and the determination threshold value of the horizontal displacement.

As the initial value of the forward distance, the actual measured value of the forward distance to the target T measured by each of the forward distance measuring devices 120 at the time when the forward block 3a starts to slide is adopted. As the initial value of the separation distance, the measured value up to the rail 21 measured by each side distance measuring device 110 at the time when the front block 3a starts to slide is adopted.

The determination threshold value is the upper limit of the horizontal displacement in the direction perpendicular to the progress based on the initial value of the separation distance, the width of the rail 21, the distance between the front block 3a and the rising wall 2a, and the design information of the roof frame 3. set. The front distance initial value, separation distance initial value, and horizontal displacement determination threshold set as described above are stored in the storage unit provided in the arithmetic processing unit 132 via the input unit 131 of the displacement detection device 130. .

<<Sliding movement of front block 3a>>
After carrying out the above preparations, the slide device 15 is operated to start the slide movement of the front block 3a as shown in FIG. 2(b). While the front block 3a slides on the pair of rails 21, the moving object monitoring system 100 continuously measures the distance from the rails 21 with the lateral distance measuring device 110, and obtains the measured separation distance. do. In addition, the forward distance measuring device 120 continuously measures the distance to the target T to obtain the measured forward distance. These measured values are sent to the displacement detection device 130 .

≪Monitoring of front block 3a: movement distance≫
When the displacement detection device 130 receives the front distance actual measurement value via the input unit 131, the arithmetic processing unit 132 receives a command from the movement amount detection unit 1323, and determines the movement distance (movement amount) of the front end of the front block 3a in the traveling direction. , the difference in left and right movement distances is calculated. The movement distance can be obtained by calculating the difference between the front distance actual measurement value and the front distance initial value.

When the movement distance (movement amount) of the front block 3a and the movement distance difference between the left and right front ends in the traveling direction are calculated, the arithmetic processing unit 132 outputs the calculation result to the display device 134 via the output unit 133 . 10, it can be seen that the left front end (L side) of the front block 3a in the traveling direction has moved 40.788 m, and the right front end (R side) in the traveling direction has moved 40.795 m. As a result, it can be seen that the movement distance difference is within about 7 mm. Such moving distance and moving distance difference are calculated each time the front distance actual measurement value is calculated, and the output value of the display device 134 is updated accordingly.

<<Monitoring of front block 3a: horizontal displacement (positional deviation amount)>>
When the displacement detection device 130 receives the distance measurement value via the input unit 131, the arithmetic processing unit 132 receives a command from the horizontal displacement detection unit 1321 and calculates the horizontal displacement of the front block 3a in the direction perpendicular to the traveling direction. The horizontal displacement can be obtained by calculating the difference between the measured separation distance and the initial separation distance.

When the horizontal displacement is calculated in the vicinity of the four corners of the front block 3 a in plan view, the arithmetic processing section 132 outputs the calculation result to the display device 134 via the output section 133 . 10, it can be seen that the front block 3a is horizontally displaced by 18 mm on the left rear end (BL side), by 34 mm on the right rear end (BR side), and leftward (L side). Also, it can be seen that the horizontal displacement is 19 mm on the left side of the front end (FL side), 20 mm on the right side of the front end (FR side), and on the left side (L side).

That is, it can be determined that the front block 3a tends to be eccentric to the left (L side) as it slides. Such a horizontal displacement is calculated each time the actual measurement value of the separation distance is calculated, and the output value of the display device 134 is updated accordingly.

Further, the arithmetic processing unit 132 receives a command from the horizontal displacement detection unit 1321, and each time the horizontal displacement is calculated, it compares the horizontal displacement near each of the four corners of the front block 3a in a plan view with a predetermined judgment threshold. If the horizontal displacement is greater than the determination threshold at at least one of these locations, it is determined that the horizontal displacement of the front block 3a is "abnormal".

When it is determined that there is an abnormality in the horizontal displacement, the arithmetic processing section 132 issues a warning message to the display device 134 such as a monitor installed in the central control room of the slide device 15 via the warning output section 1332 . When the worker receives the warning message on the display device 134, the operator temporarily suspends the operation of the slide device 15 and visually confirms the horizontal displacement of the front block 3a with respect to the rail 21, or adjusts the slide device 15 appropriately to move forward. It is sufficient to take appropriate measures such as adjusting the position of the block 3a.

≪Monitoring of front block 3a: Amount of expansion and contraction≫
When the displacement detection device 130 acquires the horizontal displacement near the four corners of the front block 3a in plan view, the arithmetic processing unit 132 receives a command from the expansion/contraction amount detection unit 1322, and calculates the expansion/contraction amount of the front block 3a in the direction perpendicular to the traveling direction. . The amount of expansion and contraction on the rear end side in the traveling direction can be calculated from the difference in horizontal displacement between the left rear end (BL side) and the right rear end (BR side). The amount of expansion and contraction on the front end side in the traveling direction can be calculated from the difference in horizontal displacement between the left front end (FL side) and the right front end (FR side).

After calculating the expansion/contraction amount of the front block 3 a , the arithmetic processing unit 132 outputs the calculation result to the display device 134 via the output unit 133 . It can be seen from FIG. 10 that the forward end of the front block 3a in the direction of travel is shrunk by 1 mm, and the rear end thereof in the direction of travel is shrunk by 16 mm. The expansion/contraction amount in the direction perpendicular to the traveling direction is calculated each time the horizontal displacement of the front block 3a is calculated, and the output value of the display device 134 is updated accordingly.

As described above, by adopting the moving body monitoring system 100, the horizontal displacement of the front end side and the rear end side of the front block 3a in the traveling direction with respect to the rail 21 can be displayed by a display device such as a monitor installed in the central control room of the slide device 15. 134 can be constantly monitored and managed with high accuracy and efficiency. Therefore, the operator can omit the work of monitoring the behavior of the front block 3a, and it is possible to achieve significant labor saving.

When the front block 3a reaches the predetermined position, the operation of sliding the front block 3a is finished. Next, as shown in FIGS. 3(a) and 3(b), the intermediate block 3b is constructed on the working stage 7 by the same procedure as the assembly process of the front block 3a, and then the front block is assembled via the connecting steel frame 10. 3a to construct a unit block 3d.

After that, in the same procedure as the step of moving the front block 3a, the moving object monitoring system 100 performs sliding movement while constantly monitoring the unit block 3d, and manages the expansion/contraction amount in the direction perpendicular to the movement and the horizontal displacement in real time. . In the same procedure, as shown in FIGS. 4(a) and 4(b), the rear block 3c is constructed and connected to the unit block 3d via the connecting steel frame 10 to construct the roof skeleton 3. As shown in FIG. In this way, the roof skeleton 3 supported by the walls 2 is constructed by the slide construction method.

The mobile object monitoring system and roof construction method of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
