[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure construction apparatus used for laying a structure such as a concrete unit for a house or various large-sized industrial machines at a predetermined position in a building site or a factory site. It relates to the construction method.

[0002]

2. Description of the Related Art Conventionally, a concrete unit made of precast concrete used for a house is known. Such concrete units can not only be mass-produced at low cost in factories, but also can minimize on-site construction, thus contributing to lower building costs. It is thought to be. By the way, such a concrete unit needs to be adapted to the space of a room of 4.5 tatami mats for a small one and 12 tatami mats for a large one. 20t). Therefore, it is practically extremely difficult to carry out transportation using public roads from the factory to the construction site in a state where laws and regulations have been cleared, and this has become a bottleneck and is a reason why concrete units cannot be spread.

[0003] The applicant has previously invented a basement structure P which is a kind of concrete unit as shown in FIG. 16 (Japanese Patent No. 2944565), and manufactures this basement structure P in a factory. Transport from a public road to the construction site became possible, which spurred the spread of the basement structure P.

As shown in FIG. 16A, the basement structure P has a lower structure P1 made of precast concrete mass-produced in a factory and an upper structure laminated on the lower structure P1. And the lower structure P
1 by stacking the superstructure P2 on
(B), a basement structure P is formed. In this way, by dividing the basement structure P into upper and lower structures P1 and P2, each structure P
By displacing 1 and P2 by 90 ° (ie, turning over) and setting them in a vertical posture, it becomes possible to mount the vehicle on a special transport vehicle.

[0005] The above-mentioned structures P1 and P2 conveyed to the construction site are first suspended using a large crane truck K in a vertical hole H (FIG. 17) in which the lower structure P1 has been excavated in advance. Subsequently, the upper structure P2 is suspended and stacked on the lower structure P1, whereby the basement structure P is constructed in the vertical hole H of the predetermined site G.

[0006]

By the way, FIG.
FIG. 4 is a plan view illustrating the arrangement of the crane trucks at the construction site. As shown in this figure, for example, when constructing a basement structure P of 6 tatami mats, the plane dimension is approximately 5 m × with some allowance. In addition to excavating a vertical hole H of about 7 m in advance, an open space G1 for rolling over the structures P1 and P2 adjacent to the vertical hole H must be secured, and a work area G2 for the crane K to work must be secured. So, after all,
In order to construct a basement structure P of 6 tatami mats (external dimensions of 16.5 m ² ), approximately 17 m × approximately 13 m (221 m ² ) and approximately 1
Three times as large is required.

[0007] Therefore, even if the basement structure P can be carried to the construction site, there is a problem that the basement structure P cannot be practically constructed in a narrow site in an urban area.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a structure construction apparatus and a structure construction apparatus capable of easily and efficiently constructing a structure such as a concrete unit in a narrow site. It aims to provide a construction method.

[0009]

According to the first aspect of the present invention,
A structure construction apparatus provided for constructing a structure at a predetermined position by hanging down the suspended structure,
A gate-shaped frame structure composed of a pair of strut members opposed to each other and a beam material erected between the tops of the strut members, a crane device for suspending the structure provided on the beam material, and each of the strut members A predetermined number of wheels for movement provided with at least one driving wheel, a driving unit for driving the driving wheel, and a wheel direction changing unit for changing a direction of the wheel, wherein the driving unit includes: The drive wheel is configured to be able to drive forward and reverse independently of the other drive wheels, and the wheel direction changing means changes the traveling direction of the portal structure between horizontal and vertical by changing the direction of the wheels by 90 °. It is characterized in that it is configured to be able to convert between.

According to the present invention, the gate-shaped frame is moved by driving the driving means, and the structure placed on the ground is positioned between the pair of support members. Is straddled. In this state, the structure is lifted by the crane device provided on the beam material, the portal structure is continuously moved to the construction position of the structure, and then the structure is lowered by driving the crane device, whereby the structure is lifted. Installed in place.

As described above, since the structure is always positioned substantially at the center of the portal structure while straddling the portal structure,
The suspended state is always stable, and the lifting and lowering of the structure by driving the crane device is always performed in a stable state. In addition, since the supporting columns are provided with driving wheels, movement of the portal frame structure to the construction position in a state where the structure is suspended can be easily performed by driving the driving means. Then, the structure is easily constructed by a simple operation that does not require skill, such as simply hanging down the structure suspended by the portal frame structure while straddling the construction position.

[0012] Therefore, in the installation work of a conventional structure in which an extremely heavy structure is lifted or lowered by an arm using a large crane truck, first of all, the operation of the crane must be performed by a skilled person. In addition to the fact that the center position of the crane truck and the suspended position of the structure do not match even if a skilled person operates the crane, the suspended state of the structure is not stable, Although there is a problem that the installation work is very difficult, such inconvenience is completely solved by using the structure construction apparatus of the present invention, and the construction of the structure is extremely easily performed.

[0013] Since each column is provided with a wheel driving means for driving a driving wheel, the structure construction apparatus can be made to run by itself, so that the work of installing heavy objects can be performed efficiently. become.

[0014] Further, by operating the wheel direction changing means, it is possible not only to move the structure construction apparatus straight, but also to turn it, which contributes to the efficiency of the installation work of heavy objects. In particular, by configuring so that the direction of the wheel can be changed by a maximum of 90 ° by operating the wheel direction changing means, it is possible to switch between the traverse and the traverse of the structure construction apparatus in a very short time without turning. Thus, the efficiency of the installation work of heavy objects is further improved.

Further, when performing the installation work with a large crane truck, it is necessary to secure the position occupied by the crane truck on the site of the construction site, and also to secure the position where the structure is temporarily placed. Instead, a work area that is several times larger than the construction area of the structure is required, whereas according to the present invention, the portal frame can be straddled over the structure. And the work area of the structure construction apparatus can be shared, whereby the work area can be reduced to a fraction of the work area conventionally required.

Therefore, according to the present invention, the inconvenience that it has conventionally been difficult to construct a large structure in a narrow site in an urban area is solved, and the structure can be easily installed even in a narrow site. Be able to construct. Eliminates the inconvenience that construction has been difficult but has not been widely spread, especially when the structure is a concrete unit for basement rooms, despite the high demand for securing a comfortable living space on a narrow site in the city. And contribute to the spread of concrete units for basements.

According to a second aspect of the present invention, in the first aspect of the present invention, the crane device includes a crane body movable forward and backward along a beam, a crane body mounted on the crane body, and a structure. It is characterized by comprising a hanging strip hung at at least two points, and droop length adjusting means for adjusting the droop length of each hanging strip from the crane body.

In the present invention, the hanging strip is a long string-shaped object used for hanging a heavy object such as a rope, a chain, or a band. According to the present invention, the structure is provided at two points (two points on the front and back surfaces in total, four points) by two hanging strips per one wall surface having the same hanging length.
In the state of being suspended in the structure, the droop length adjusting means is driven to sequentially reduce the droop length of one of the hanging strips, while the length of the other hanging strip is sequentially increased, whereby the structure is gradually inclined. ,
Eventually, the rollover state is shifted by 90 °. Therefore, for the convenience of transportation from the special transport vehicle, it is possible to easily turn the heavy object unloaded vertically in the horizontal position, which is the construction posture of the heavy object.

The third aspect of the present invention is the first or second aspect.
In the invention described above, the support member includes a lower support member and an upper support member connected to the lower support member so as to be vertically movable, and a support vertical movement means for moving the upper support member up and down. It is characterized by having.

According to the present invention, first, the beam can be adjusted to the height of the heavy object by lifting and lowering the beam by driving the column vertical movement means. Then, in a state in which the heavy object is supported on the beam member via a rope or the like, the upper support member is protruded upward from the lower support member by driving of the support vertical movement means, so that the heavy material is connected to the rope or the like. In this state, the construction equipment is moved to the construction position, and then the upper strut members are stored in the lower strut members. The held heavy object descends and is installed at a predetermined position. In this way, by configuring the upper column to be able to be raised and lowered, it is possible to expand the range of vertical movement of the heavy object in combination with the crane device. In this case, the operation of suspending and lowering the concrete unit into the vertical hole is performed more smoothly.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the beam member is provided between the support members so that the effective length between the support members is variable. It is characterized by having.

According to the present invention, by adjusting the effective length of the beam in accordance with the width of the heavy object, it is possible to cope with heavy objects having various widths.

According to a fifth aspect of the present invention, there is provided a method for constructing a structure using the structure constructing apparatus according to any one of the first to fourth aspects, wherein the structure is mounted on the ground in an installation posture. And the drive means provided on one support and the drive means provided on the other support are reversely driven, respectively. After turning the portal structure around its center to change the hanging posture of the portal structure to the structure to match the plane shape of the construction position, the portal structure The present invention is characterized in that the frame structure is moved to a position straddling the construction position and the structure is suspended.

According to the present invention, in the structure placed on the ground in the installation posture, the suspension direction can be set arbitrarily by turning the portal frame structure by reversely driving the driving means provided on each column. Is done. Accordingly, since the turning can be easily performed to change the direction of the structure so as to match the preset construction position, the direction of the structure can be changed by operating the lifting arm of the large crane truck as in the related art. As compared with the case of converting, the structure can be completed in a narrow work area since the structure is straddled by the portal frame, and the conversion work can be performed easily and safely.

Once the direction of the structure has been changed, the portal frame is moved to the construction position, straddled the construction position, and then the structure is hung down. Installation work becomes more efficient.

In the transfer step, the portal structure lifted by the crane device between the portal structures and transferred to the construction position of the structure is transferred to the construction position. Then, the structure is suspended at the construction position in the suspension process, whereby the construction of the structure at the construction position is completed. By executing each of these steps using the structure construction apparatus, the same functions and effects as those of the first to fourth aspects of the invention can be obtained.

The chain block 71 can be hung from the beam 3 via the traveling carriage 73 also by inserting the rope R into the binding hole 732a and binding.

The operation of the present invention will be described below with reference to FIGS. First, FIG. 9 is an explanatory diagram for explaining a method of mounting the structure construction apparatus 1 on a transport vehicle, and FIG.
Is a state immediately before the structure construction device 1 is mounted on the transport vehicle 10, (b) is a state where the structure construction device 1 is being mounted on the transport vehicle 10, (c) is a state where the structure construction device 1 is mounted on the transport vehicle 10. Indicates a state mounted on the transport vehicle 10, respectively.

A transport vehicle 10 for transporting the structure construction apparatus 1
For this purpose, a special vehicle for transporting vehicles as shown in FIG. 9 is used. The transport vehicle 10 includes a vehicle main body 11 and a tiltable loading platform 12 supported on a rear frame 14 of the vehicle main body 11 so as to be rotatable around a horizontal axis 13. When the transport vehicle 10 travels, as shown in (c) of FIG.
4 is rotated in a clockwise direction around the horizontal axis 13 during loading and unloading, as shown in FIG. 9 (a). Set to state. This makes it possible to load the load on the tiltable loading platform 12 using the tilt without using a working machine such as a crane. The tiltable loading platform 12 is normally set at the tilt angle α in a state where the tilting attitude is set.
Is set to approximately 10 °.

When the structure construction apparatus 1 is transported, first, as shown in FIG.
9 in a widthwise movable state in which the beam 3 extends in the direction in which the beam 3 extends (FIG. 6). As shown in (b), the vehicle is moved onto the tiltable carrier 12 by climbing the slope of the tiltable carrier 12.

After the structure construction apparatus 1 has been moved onto the tiltable load table 12, the tiltable load table 12 is rotated counterclockwise around the horizontal axis 13, thereby, as shown in FIG. ,
The tiltable loading platform 12 is now stacked on the rear frame 14, and the mounting of the structure construction apparatus 1 on the transport vehicle 10 is completed. Next, the transport vehicle 10 is moved to the construction site, and the tiltable carrier 12 is rotated clockwise about the horizontal axis 13 to obtain the state shown in FIG. In this state, the structure construction device 1 is sent backward to
As shown in (a) of FIG.
Unloaded from zero.

In the present embodiment, the driving force of the traveling motor 55a of the structure
Since the vehicle has a climbing ability capable of climbing a slope of 0 °, the structure construction apparatus 1 can be mounted on a commercially available transport vehicle 10 by self-propelled operation, and a work machine such as a crane can be used. Since there is no need to use, work efficiency is improved and work costs are reduced.

Next, construction of the structures P1 and P2 using the structure construction apparatus 1 carried to the construction site will be described. In addition, the structures P1 and P2 are separately carried to the construction site using another dedicated transport vehicle. However, since the structures P1 and P2 carried to the construction site are unloaded in a vertically installed state with their wall surfaces grounded, first,
This is turned over by 90 ° and placed in a horizontal position (that is, the structure P
1, P2 is actually installed).

FIG. 10 is an explanatory view for explaining a rollover method for rolling over the structures P1 and P2 in a vertically placed state by 90 ° using the structure construction apparatus 1. FIG.
(B) is a state immediately before the structures P1 and P2 are lifted by the structure rollover device 72 in the vertical position, and (b) is a state in which the lifted structures P1 and P2 are sequentially rolled by the drive of the structure rollover device 72. Is shown.

First, the structures P1 and P2 are sandwiched between a pair of support members 2 with the respective walls facing the support members 2 by running of the structure construction apparatus 1, and in this state, the rollover sprocket 74 is held. Overturned chain 7
5 is the upper left end of the upright structures P1 and P2 and the first locking point Z1 formed on the wall surface thereof. While the other lower end is the lower right end of each of the structures P1 and P2, and the second engagement point Z2 formed on the wall surface thereof.
Is locked. At each of the locking points Z1 and Z2, a protruding piece for locking is protruded, and a rollover chain 75 is provided.
Each end is provided with a hook for locking to the protruding piece.

Next, by raising the upper column member 22 to a predetermined height by driving the column expansion / contraction means 6 (FIG. 1), the structures P1 and P2 are turned from the state shown in FIG. The state is suspended by 75.

In this state, the roll sprocket 74 is rotated gently counterclockwise around the support shaft 74a by the drive of the roll chain 75, so that the rolled chain 75 rotates around the sprocket 74. Is moved counterclockwise.

In this case, since the length of the rollover chain 75 is constant, the above-described movement of the rollover chain 75 gradually increases the distance between the first locking point Z1 and the rollover sprocket 74, The distance between the two locking points Z2 and the rollover sprocket 74 gradually decreases, and as shown in (b)-of FIG. 10, the structures P1 and P2 are sequentially inclined, and finally, the structures P1 and P2 of FIG. (B) As shown in-, the posture is horizontal.

Then, when the structures P1 and P2 are in the horizontal posture, the rollover motor 76 (FIG. 7) is stopped, whereby the horizontal posture of the structures P1 and P2 is maintained. In this state, by lowering the beam 3 by reverse driving of the column extending / contracting means 6, the overturning of the structures P1 and P2 is completed as shown in FIG. In addition,
In the state shown in (b)-of FIG. 10, when the constructions P1 and P2 which are immediately suspended are suspended in the vertical holes H, the constructions are carried out without the structures P1 and P2 being temporarily lowered to the ground. The apparatus 1 is moved to the construction position, and the work of suspending the structures P1 and P2 is immediately performed.

If the structures P1 and P2 in the vertical posture are rolled over using such a structure rollover device 72, the tension applied to the front and rear roll chains 75 distributed via the roll sprocket 74. Is the structure P1,
Since it is possible to always maintain the same and always constant regardless of the change in the posture of P2, a stable and safe rollover operation is realized as compared with the case where a conventional working machine such as a crane truck is used. .

FIG. 11 is an explanatory view for explaining the work of installing the structures P1 and P2 in the vertical hole H by the structure construction apparatus 1. FIG. 11A is a diagram in which the structures P1 and P2 are suspended. (B) shows a state in which the structure construction apparatus 1 is positioned over the vertical hole H, and (b) shows a state in which the structures P1 and P2 are being suspended in the vertical hole H, respectively.

When mounting the structures P1 and P2 in the vertical hole H, first, the structures P1 and P2 placed on the ground shown in (b)-of FIG.
1 and the structure construction apparatus 1 is run continuously, so that the pair of support members 2 straddle the vertical hole H as shown in FIG. Before the state shown in FIG. 11A, the distance between the pair of support members 2 is set in advance according to the size of the vertical hole H.

Next, by lowering the upper support member 22 slowly by driving the support expansion / contraction means 6, the beam 3 integrated with the upper support member 22 gradually lowers, and as a result, as shown in FIG. As shown by the solid line, the structures P1,
P2 is in a state of being suspended down to the opening position of the vertical hole H. In this state, by operating the chain block 71 to slowly unwind the chain C, the structure P
1 and P2 are gently hung down, and FIG.
As shown by a two-dot chain line in FIG.

FIG. 12 is a plan view for explaining the turning of the structure construction apparatus 1. FIG. 12A shows the position setting of the structure construction apparatus 1 so that the beam 3 extends in the left-right direction. (B) shows a state in which the position of the structure construction apparatus 1 is set such that the beam 3 extends in the front-rear direction. First, in the state shown in FIG. 12A, the directions of the wheels 54 and 57 are changed so that the axes indicated by dashed lines pass through the center point O of the beam 3. In this state, one drive wheel 54 and the other drive wheel 54 are driven in opposite directions. In other words, the driving wheels 54 are driven in the same direction around the axis while viewing the center point O from each driving wheel 54.

Then, for example, looking at the center point O, each drive wheel 5
When the object 4 is rotated clockwise around the axis, the structure construction device 1 turns counterclockwise around the center point O as indicated by the arrow. By stopping this turning at 90 °, as shown in FIG. 12B, the structure construction apparatus 1 is in a state where the phase is shifted by 90 ° from the position shown in FIG.

Therefore, the structure construction apparatus 1 is capable of running in the vertical and horizontal directions, and is also capable of performing such a turn, so that the installation work of the structures P1 and P2 in the narrow premises can be performed. It can be done freely according to the terrain at the site.

As described in detail above, according to the structure construction apparatus 1 of the present invention, the structures P1 and P2 are easily suspended via the ropes R on the beam members 3 straddling the vertical holes H. Since it can be in a state, by performing a simple operation of extending the chain C from the chain block 71,
The structures P1 and P2 can be easily installed in the vertical hole H, and the efficiency of the installation work is greatly improved as compared with the conventional work of installing the structures P1 and P2 using a working machine such as a large crane truck. Can be realized.

Further, as shown in FIG. 13 showing a work area of the installation work using the structure construction apparatus 1 of the present invention, when the structures P1 and P2 having a size of 6 tatami mats are installed in the vertical hole H, About 8m x about 9m including vertical hole H around H
(Approximately 72 m ² ) site (occupied area for work)
It is possible to execute all construction work for installing the structures P1 and P2 including the rollover in the vertical hole H.

On the other hand, FIG.
As described on the basis of the above, when a conventional working machine such as a large crane is used, the site area is approximately 221 m ² (17 m × 1
According to the present invention, the occupation area may be 32% larger than that of the related art, and the working area can be greatly reduced. Therefore, it has been difficult to carry the structures P1 and P2 to the construction site and to construct the structures P1 and P2 in the vertical holes H. Therefore, the construction using the concrete unit in the urban area of a large city, which has not been popularized, has conventionally been used. The construction of a building is made possible by using the structure construction apparatus 1 of the present invention, and it is considered that the construction of a building using a concrete unit will become widespread in the future.

FIG. 14 is a perspective view showing another embodiment of the structure construction apparatus 1a. In the structure construction apparatus 1a of this embodiment, the beam 3a is telescopically expandable and contractable. That is, the beam 3a is composed of a pair of rectangular tubular outer beams 33 projecting from the tops of the upper support members 22 in directions facing each other, and each side portion of the outer beam 3
3 and an inner beam material 34 which is fitted inside the sliding member 3 in a sliding contact state. The hydraulic stopper 25 is provided at the tip of each outer beam member 33. Other configurations are the same as those of the above-described structure construction apparatus 1.

According to the structure construction apparatus 1a of this embodiment, the inner beam member 34 is moved to the pair of outer beam members 33 by moving the pair of support members 2 in the facing direction by driving the traveling mechanism 5. On the other hand, it is possible to obtain the same effect as that of the previous embodiment, in which the movable length can be adjusted to adjust the effective length of the beam 3a.

The present invention is not limited to the above embodiment, but includes the following contents.

(1) In the above embodiment, the worm 56b and the worm gear 56c are employed as the wheel direction changing means 56, but the present invention is configured such that the wheel direction changing means 56 includes the worm 56b and the worm gear 56c. Instead, the directions of the driving wheels 54 and the driven wheels 57 may be changed by driving the cylinder device.

(2) In the above embodiment, the traveling carriage 73 travels in the beam 3 by the driving of the carriage traveling motor 77. However, in the present invention, the traveling carriage 73 is The invention is not limited to running by driving, and the traveling carriage 73 may be moved manually without providing the carriage traveling motor 77.

(3) In the above-described embodiment, the chain block 71 is hung on the rope R directly attached to the beam 3. The rope R is attached to the piece 731a.
May be used to suspend the chain block 71.
By doing so, the position where the structures P1 and P2 are hung by the rollover chain 75 and the position where the structures P1 and P2 are hung by the chain block 71 are always at the same position. The troublesome work of changing the hanging position of the chain block 71 every time it changes can be avoided.

(4) In the above embodiment, the wheels 54 and 57 are adopted as the traveling means in the structure construction apparatus 1, but the present invention is limited to the traveling means being the wheels 54 and 57. Instead, a crawler may be employed.

(5) In the above embodiment, the electric traveling motor 55a is used as the wheel driving means, but a hydraulic motor may be used instead of the electric traveling motor 55a.

(6) In the above embodiment, the structure construction device 1 is applied to the construction work of the basement structure P. However, the present invention is applied to the case where the structure construction device 1 is used only for the construction of the basement structure P. The present invention is not limited to the application to various types of construction, and can be applied to the construction of various buildings installed on the ground, and can also be applied to the installation of various large-sized mechanical devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG.
As shown in FIG. 5, two sets of basement structures each having a size of 6 tatami mats were connected in series to construct a basement having a size of 12 tatami mats. FIG. 15 is an explanatory view for explaining a method of performing the basement in this construction.

In this construction, the construction method according to the present invention is applied. That is, the enforcement method of the present invention relates to a structure (structure) P1, P
2 (In this embodiment, the first lower and upper structures PA1 and PA2 and the second lower and upper
1, PB2) is lifted and rolled over by a structure rollover device 72 between portal structures composed of the column members 2 and the beam members 3, and the structures P1, P rolled over in the rollover process

The method includes a position setting step of setting the position so as to be positioned, and a structure hanging step of hanging the structure to the working position by driving the crane device in a state where the portal frame is set at the working position.

First, the basement structure used in the construction of the basement will be described. In this construction, (c) of FIG.
As shown in FIG. 2, a first basement structure PA including a first lower structure PA1 and a first upper structure PA2, and a second basement structure PB including a second lower structure PB1 and a second upper structure PB2. The frontage X is joined to each other, and a basement structure P having a long depth Y is constructed by two sets of basement structures PA and PB.

Each basement structure PA, PB has basically the same structure and dimensions, but the first lower structure P
A1 is provided with a pair of pawl projections P4 in the depth Y direction extending in the frontage X direction at the bottom thereof, whereas the second lower structure PB1 is provided with a sliding projection P5 at the bottom thereof. Are the differences between the two. Each of the above ridges P4, P5
Are fitted into the pawl groove B1 and the sliding groove B2, respectively, which are recessed in the foundation B constructed at the bottom of the vertical hole H, whereby the basement structures PA, P
The positioning of B is performed appropriately.

In particular, the sliding groove B2 is formed by the first lower structure P
The sliding ridge P5 has a sloping surface corresponding to this sloping surface in addition to the forwardly sloping inclined surface toward the direction of A1, so that the sliding ridge P5 is fitted into the sliding concave groove B2. In this state, the sliding ridge P5 slides on the inclined surface of the sliding groove B2, whereby the second lower structure PB1 moves in the direction of the first lower structure PA1.
The wall surface of the first lower structure PA1 presses the wall surface of the first lower structure PA1, whereby the two basement structures PA and PB are continuously connected to each other with no gap therebetween.

Then, such two sets of basement structures P
A, PB is installed in the vertical hole H by the first lower structure PA.
1, the first upper structure PA2, the second lower structure PB1, and the second upper structure PB2 were performed in this order.

First, as shown in FIG.
The lower structure PA <b> 1 is formed by the beam member 3 and the first lower structure PA by the rollover operation (the rollover process (see FIG. 10)) performed earlier.
1 is carried in a working area adjacent to the vertical hole H by the structure construction device 1 (two-dot chain line) so that the depth Y direction is parallel to the depth Y direction. The first lower structure PA1 cannot be suspended in the vertical hole H while straddling H. Then, the first lower structure PA1 is once suspended, and in this state, the structure construction device 1 is turned by 90 ° around its center position, and by doing so, the structure construction device 1 is moved to the position shown in FIG. As shown by the solid line in (a), the first lower structure PA1 was straddled in the frontage X direction.

In this state, the first lower structure PA1 is lifted again, and the structure construction apparatus 1 is moved as shown by an arrow in FIG. 15A (transfer step), and is shown in FIG. As described above, the structure construction apparatus 1 straddles the vertical hole H in the frontage X direction and sets the position at the construction position (position setting step).

In this state, the first lower structure PA1 is suspended by operating the chain block 71, and the pawl projections P4 are fitted into the pawl grooves B1 of the base B, as shown in FIG. As shown in the lower left of the vertical hole H,
The first lower structure PA1 is installed on the foundation B, and the same operation as above is performed on the first upper structure PA2.
It was stacked on the first lower structure PA1 in the vertical hole H (structure hanging process).

Next, the same operation as described above is performed on the same second lower structure PB1 so that the second lower structure PB1 is adjacent to the first basement structure PA as shown in FIG. Was suspended in the vertical hole H. At this time
The suspension operation was performed with great care so that the sliding ridge P5 at the bottom of the lower structure PB1 was fitted into the sliding groove B2 of the foundation B.

After the sliding ridge P5 is fitted into the sliding concave groove B2 by this operation, the second lower structure PB1 is lowered by operating the chain block 71.
Is guided by the inclination of the sliding groove B2 and the first lower structure PA
1 so that the second substructure PB1
15 (c) and (d) of FIG. 15 was confirmed to be installed on the foundation B in a state in which the left outer wall surface was in close contact with the right outer wall surface of the first lower structure PA1.

Next, by suspending the second upper structure PB2 on the second lower structure PB1 by the same operation as described above, as shown in FIG. 15D, two sets of basement structures P ( First basement structure PA and second basement structure P
B) was in the state where it was constructed in the vertical hole H.

As can be seen from this embodiment, the structural construction apparatus 1 of the present invention rolls the basement structure from the vertical position in which the wall surface is brought into contact with the work area to the horizontal position immediately before installation. In addition, since the basement structure can be traversed, traversed, and swung freely while the basement structure is suspended, the structure can be freely moved or positioned according to the shape of the vertical hole H or the combination of the structures. It was confirmed that the installation of the basement structure could be performed extremely efficiently.

[0107]

According to the first aspect of the present invention, a pair of pillar members opposing each other and a beam material provided between the tops of these pillar members constitute a gate-shaped frame structure. Moving wheels are provided at the lower part, and a crane device is provided on the beam for hanging the structure.The rolling of the wheels moves the portal frame, and a pair of structures placed on the ground , The portal frame can straddle the structure. In this state,
The structure is lifted by the crane device provided on the beam material, and then the portal frame is moved to the construction position of the structure.Then, the structure is suspended by the drive of the crane device, and the structure is moved to the predetermined position. Can be installed.

As described above, since the structure is always positioned substantially at the center of the portal frame while straddling the portal frame,
The suspended state of the structure can always be kept stable, and the lifting and lowering of the structure by driving the crane device can always be performed in a stable state. In addition, since the pillars are provided with wheels, the portal frame in a state where the structure is suspended can be easily moved to the construction position.
Then, the structure can be easily constructed at the intended place by a simple operation without skill, such as simply hanging down the structure suspended by the portal frame structure straddling the construction position. .

Further, when performing the installation work with a large crane truck, it is necessary to secure the position occupied by the crane truck on the site of the construction site, and also to secure the position where the structure is temporarily placed. Instead, a work area several times wider than the construction area of the structure is required, whereas according to the present invention, the portal frame can be straddled by the structure, And the work area of the structure construction apparatus can be shared, whereby the work area can be reduced to a fraction of the work area conventionally required.

Therefore, according to the present invention, it is possible to solve the inconvenience that it has conventionally been difficult to construct a large structure in a narrow site in an urban area. Can be easily constructed. Especially when the structure is a concrete unit for basement,
Despite the high demand for securing a comfortable living space on a narrow site in an urban area, the inconvenience of not being popularized due to the difficulty of construction has been resolved, and it can contribute to the spread of concrete units for basements. .

[0111] Then, since the structure construction apparatus can be driven by the driving of the wheel driving means, it is possible to compare the structure construction apparatus with another vehicle by pulling and moving the structure construction apparatus.
The work of installing heavy objects can be performed more efficiently.

Further, since the wheel direction changing means for changing the direction of the wheels is provided, it is possible to turn the structure construction apparatus not only in a straight line but also by turning the wheel direction changing means. It can contribute to efficiency.

In particular, by switching the direction of the wheels by a maximum of 90 ° by operating the wheel direction changing means, the switching between the traverse and the traverse of the structure construction apparatus can be performed in a very short time without turning. Is possible, and the work of installing heavy objects can be made much more efficient.

According to the second aspect of the present invention, the structure is mounted on the crane main body and the structure is provided at least two per wall.
Since the hanging strips hanging at points (total of 4 points on the front and back walls) and the hanging length adjusting means for adjusting the hanging length of each hanging strip from the crane body are provided, the structures have the same hanging length. While hanging at two points with two hanging strips per one wall set in the above, while the hanging length of one hanging strip is sequentially shortened by driving the hanging length adjusting means, the other hanging strip is By gradually increasing the droop length, the structure gradually tilts and finally reaches 90 °
A displaced rollover state can be achieved. Therefore, for convenience of transportation from the special transport vehicle, the heavy object unloaded vertically can be easily rolled over to the horizontal posture, which is the construction posture of the heavy object, and the work efficiency can be improved.

According to the third aspect of the present invention, the support member is composed of the lower support member and the upper support member connected to the lower support member so as to be vertically movable. Because of the provision of vertical support
First, the beam can be adjusted to the height of the heavy object by lifting and lowering the beam by driving the column vertical movement means. Then, in a state where the heavy object is supported on the beam member via a rope or the like, the upper column member is projected upward from the lower column member by driving the column vertical movement means,
While the heavy object can be suspended from the beam material via a rope or the like, the structure construction device is moved to the construction position in this state, and then the upper support member is stored in the lower support member. By moving, the heavy object suspended on the beam material can be lowered and installed at a predetermined position. In this way, by configuring the upper column to be able to be raised and lowered, it is possible to expand the range of vertical movement of the heavy object in combination with the crane device. In this case, the operation of suspending and lowering the concrete unit in the vertical hole can be performed more smoothly.

According to the fourth aspect of the present invention, since the effective length of the beam is adjustable, even if the width of the heavy object to be suspended changes, the effective length of the beam is adjusted. It is possible to cope with a change in size, and the versatility of the structure construction apparatus can be improved.

According to the fifth aspect of the present invention, the direction of suspension of the structure placed on the ground is arbitrarily changed by turning the portal frame structure by reversely driving the driving means provided on each column. can do. Therefore, since the structure can be easily turned by this turning so as to match the preset construction position, the direction of the structure can be changed by operating the lifting arm of the large crane truck as in the past. Compared to the case where the structure is provided, the structure is straddled by the portal frame, so that the work can be completed in a narrow work area and the conversion work can be performed easily and safely.

Then, once the direction of the structure has been changed, the portal frame is moved to the construction position, straddled the construction position, and then the structure is hung down. This is extremely effective in achieving overall efficiency.

According to the sixth aspect of the present invention, in the rollover step, the structure unloaded with the outer wall surface in contact with the ground is
In the transfer process, the crane is lifted by the crane device between the portal structures and transferred to the construction position of the structure. In the position setting step, the portal-type frame structure transferred to the position is set so that the construction position is located between the respective strut members, and then in the suspension step, the structure is suspended at the construction position, whereby the structure is suspended. Can be reliably and easily constructed at the construction position. By executing each of these steps using the structure construction apparatus, it is possible to obtain the same functions and effects as those of the first to fourth aspects of the present invention.
