TECHNICAL FIELD OF THE INVENTION
The present invention relates to a case in which a general road facing an entrance of a construction site is narrow and it is difficult to park and stop a work vehicle such as a truck, a crane, and a backhoe, or the foundation of a building is disposed on the entire site. When a work vehicle cannot be brought in and out of the construction site and parked and stopped, the work vehicle can be easily brought in and out of the construction site, parked and stopped, and can be used for normal construction work. Related to the construction method of boarding.
[0002]
[Prior art]
As is well known, when constructing a building, first, foundation work is performed on the site, then skeleton work and finishing work are performed sequentially, but those works are carried by transporting various building materials and hanging them. Work vehicles such as trucks, cranes, and backhoes for carrying out freight work are parked and parked in construction sites or on general roads having relatively wide roads facing entrances and exits of the construction sites. However, is have you in recent years, there is a tendency to build a building full site by effectively utilizing the land area, in particular, the current situation is a long building of the depth is increasing in urban areas, in order that It becomes impossible to carry the work vehicle into and out of the construction site, make it impossible to park and stop, and when the width of a general road facing the entrance of the construction site is narrow, such as a pedestrian or a traveling vehicle, There is an increasing problem that the vehicle cannot be parked and stopped there so that construction work cannot be performed.
[0003]
Therefore, in the past, inefficient means of carrying out various construction materials by relying on humans to carry out building work has been used, or a foundation located on the back side with respect to an entrance of a building site has been firstly constructed. Construction work is carried out with the work vehicle brought in and parked in front of the construction site, and finally the foundation is arranged in front of the construction site where the work vehicle was parked and stopped. A two-segment system is adopted in which the building is constructed and construction work is performed to construct the entire building.
[0004]
[Problems to be solved by the invention]
However, in the above prior art, both together poor work efficiency, the construction period there is a problem that will have the high cost as well as prolonged. In addition, when relying on manual labor, not only does the body fatigue increase, but it also poses a problem in terms of work safety.
[0005]
[Means for Solving the Problems]
The present invention has been made in view of the above circumstances, and in the means of claim 1, a work vehicle having an outrigger portion on a base outside a base surrounding a part of a base of a building is referred to as the base. Arranged so as to face each other, insert a synthetic resin foam into the gap between the lower end of this outrigger part and the base caused by shortening the outrigger part, construct a new base, and then replace the outrigger part. A synthetic resin foam is inserted into a gap between the lower end of the traveling portion of the working vehicle and the base caused by the extension, and the upper surface of the new base is substantially the same height as the upper surface of the new base below the outrigger portion. the task of building such that to is were repeated until the upper surface of the new foundation below the top surface and the run of the new foundation below the outrigger portion is higher than the top end of the base The upper surface on the foundation of the interior of the foundation, the upper surface of the synthetic resin foam constituting the new foundation below the traveling portion and the substantially upward as high as the so as to put the synthetic resin foam The work vehicle is moved in a state where the outrigger portion is shortened, then parked and stopped at a predetermined location, and construction work corresponding to the type of the work vehicle is performed.
[0006]
In the means according to claim 2, the synthetic resin foam used as a new base of the outrigger portion and / or the traveling portion after the work vehicle has passed is reused as a base in the traveling direction of the work vehicle. is there.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 and 2, the site 1 is a slender rectangular site 1 in which one shorter side faces a narrow one-way road 2 and the other longer side enters the depth direction. . Since the building foundation 3 is already almost completely laid in the site 1, the work vehicle 4 cannot be parked and stopped. Further, since the road 2 is narrow, the work vehicle 4 cannot be parked and stopped here. Therefore, in order to put the work vehicle 4 in the foundation 3 of the site 1, the work vehicle 4 traveling on the one-way road 2 as shown in FIG. The direction is changed by steering operation and forward / backward switching so as to be perpendicular to one side of the site 1 facing the road 2 so as to face each other.
[0008]
After such a posture is established, as shown in FIG. 3, the outrigger portion 5 of the working vehicle 4 is sufficiently lifted to form a gap (X1) between the outrigger portion 5 and the surface of the base 6 which is the ground surface. As shown in FIG. 4, the synthetic resin foam 8 on which the tread plate 7 is mounted is inserted into the top so as to fill the gap (X1).
[0009]
Since the tread plate 7 is used for dispersing the load of the work vehicle 4 transmitted through the four outrigger portions 5 to the upper surface of the synthetic resin foam 8, a hard plate, for example, a plywood is preferable. . The synthetic resin foam 8 preferably has a large compressive strength, and an extruded foamed polystyrene plate is one example. The shape and size of the synthetic resin foam 8 are not particularly limited. For example, it is sufficient to use a generally commercially available material having a thickness, width, and height of 100 mm × 910 mm × 1820 mm and the like. Can respond to. When such a synthetic resin foam 8 is used, a plurality of sheets are stacked to fill the interval (X1). When the thickness of the synthetic resin foam 8 is large, the number of sheets to be overlapped may be small. However, when the thickness is small, it is difficult to finely adjust the gap. There is an advantage that is easy to do.
[0010]
Next, as shown in FIG. 5, the load of the working vehicle 4 is received by the synthetic resin foam 8 by extending and sufficiently lowering the outrigger portion 5 to lower the four tires 9 of the working vehicle 4 on the ground which is the ground surface. 6, the synthetic resin foam 8 having the tread plate 7 placed on the uppermost step as shown in FIG. 6 is placed in the gap (X2) between the four tires 9 and the surface of the base 6 caused by the lifting, as described above. To form a new base 6. Then, as shown in FIG. 7, the outrigger portion 5 is again shortened and lifted, and the tread plate 7 is removed, and then the gap (X3) formed between the outrigger portion 5 and the uppermost synthetic resin foam 8 is formed. As shown in FIG. 8, the synthetic resin foam 8 is inserted, and the tread 7 is placed on the top of the synthetic resin foam 8 to form a new base 6 to fill the gap (X3). Then, the outrigger portion 4 is extended again and lowered sufficiently downward, and as shown in FIG. 9, the load of the work vehicle 4 is received by the synthetic resin foam 8, and the tire 9 of the work vehicle 4 is a new base 6. The synthetic resin foam 8 with the tread plate 7 placed on the uppermost stage is inserted into the gap (X4) as shown in FIG. 10 to form a new base 6 again.
[0011]
At this stage, if the lower end of the tire 9 is still lower than the top end of the foundation 3, the operations of FIGS. 7 to 10 are repeated to lift the tire 9 to a position slightly higher than the top end of the foundation 3. When the height of the foundation 3 is low, the work may be completed by the operations shown in FIGS. 3 to 6. However, the height of the foundation 3 is generally about 480 mm, and the lifting height by extension of the outrigger portion 5 is reduced. Since it is within the range of 300 to 400 mm, the operation of lifting the tire 9 is normally completed by repeating the operations of FIGS. 3 to 10 twice.
[0012]
When the lower end of the tire 9 reaches a position slightly higher than the foundation 3, the outrigger portion 5 is shortened and all is lifted, and as shown in FIG. 11, the synthetic resin foam located below the outrigger portion 5 The work vehicle 4 is moved to the inside of the foundation 3 after the treads 8 are piled up inside the foundation 3 and the tread plate 7 is placed on the uppermost step to make the height substantially equal to the height of the lower end of the tire 9. Then, as shown in FIG. 12, when the front tire 9 moves to above the synthetic resin foam 8 in the foundation 3 and the rear tire 9 advances to the position of the front tire 9, the rear tire 9 If the synthetic resin foam 8 located below and serving as the base 6 is moved to the inside of the base 3 and laminated, the synthetic resin foam 8 can be used effectively, but there are many synthetic resin foams 8. In such a case, it is sufficient to lay in advance in the traveling direction of the work vehicle 4 in the foundation 3 without performing such a moving operation.
[0013]
Then, when the work vehicle 4 further advances, as shown in FIG. 13, the synthetic resin foam 8 that has passed behind is moved forward in the direction of travel. In this way, the work vehicle 4 is moved to the traveling direction of the work vehicle 4 in order to move the synthetic resin foam 8 and the tread plate 7 which are no longer required when the work vehicle 4 passes, and the work vehicle 4 is After finishing the movement beyond 3, the synthetic resin foam 8 and the tread plate 7 are laminated below the outrigger portion 5 as needed, and then the outrigger portion 5 is extended and lowered to stabilize the work vehicle 4, and thereafter Then, the work according to the purpose of the work vehicle 4 is started.
[0014]
When working for a long time, since the lower end of the outrigger portion 5 has a small contact area with the tread plate 7, for example, as shown in FIG. If the lower end of the outrigger portion 5 is placed on the upper side, the load of the work vehicle 4 can be dispersed over a wide range of the tread plate 7, and the durability of the synthetic resin foam 8 can be improved.
[0015]
When the work vehicle 4 is moved halfway depending on the work content, the synthetic resin foam 8 and the tread plate 7 form a road surface slightly higher than the foundation 3 in the traveling direction of the work vehicle 4 by the same work procedure as described above. And move it.
[0016]
When the work by all the work vehicles 4 is completed, the work vehicle 4 can be lowered on the one-way road 2 by performing the work reverse to the above-described work of FIGS.
[0017]
In the above embodiment, the work vehicle 4 using the tire 9 has been described. However, the same applies to the work vehicle 4 having another traveling unit such as a crawler instead of the tire. Further, the working vehicle 4 includes all working vehicles including a traveling unit such as a truck, a crane, and a backhoe described in the section of the related art, and a running unit and an outrigger unit.
[0018]
As described above, when the synthetic resin foam 8 is repeatedly used many times, even if it has high compressive strength, the durability is limited due to pain or the like. Without discarding the resin foam 8, for example, cutting it to an appropriate size and burying it in the deep foundation of a building or the back of a retaining wall, or for insulation and dehumidification under soil concrete inside the foundation It can be effectively used for backfilling soil, etc. as an alternative to soil, for example, used as a soil retaining or burying soil.
[0019]
【The invention's effect】
As is apparent from the above description, according to the first aspect of the present invention, the work vehicle can be loaded into the inside of the foundation that effectively utilizes the outrigger portion of the work vehicle, and the work according to the type of the work vehicle can be performed. . In addition, using the outrigger part and the synthetic resin foam, the work vehicle can be lifted vertically above the height of the foundation in close proximity to the foundation. Takes no space. Further, since the synthetic resin foam is light in weight, it is easy to carry and can be easily inserted and removed below the outrigger portion and the traveling portion. Further, when the synthetic resin foam is damaged by repetition of several operations, it can be effectively used as backfill soil as an alternative to soil.
[0020]
According to the second aspect of the present invention, work can be efficiently performed with a small number of synthetic resin foams. Also at this time, since the synthetic resin foam is lightweight, it can be easily moved and the work can be performed easily.
