Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a temporary floor surface on which a vehicle can run or a person can work on it, such as a temporary road or a temporary stage.

[0002]

2. Description of the Related Art For example, when constructing a building on soft ground, it is necessary to lay a temporary road for transporting a base material and the like required for work between a main road and a work site. In addition, it is necessary to lay temporary roads even at excavation sites of ruins, and such temporary roads will be removed at the end of work and restored to their original condition.

At such a site, a large construction vehicle such as a backhoe or a large crane truck is used.
These have a large weight, and since heavy objects such as steel frames are lifted and moved during the work, a large load is applied to the ground supporting them. Therefore, temporary roads must ensure safety during such work.

At such a site, a method of constructing a temporary road using a resin foam block made of, for example, foamed styrene or the like, is adopted in place of the conventionally used embankment. This construction method is a lightweight embankment construction method in which resin foam blocks are laid while being connected to each other to form a base for embankment instead of embankment with soil.

FIG. 10 shows such a conventional resin foam block. This resin foam block 1 is used by connecting a plurality of resin foam blocks 1 as shown in the figure, and includes a block unit 1a which is formed of styrene foam or the like and has a substantially rectangular parallelepiped shape, and polypropylene which covers the outside thereof. It consists of a net 2 made up of.

For example, when connecting five resin foam blocks 1, adjacent resin foam blocks 1, 1 are connected at positions P, P ... P as shown in FIG. By a series of resin foam block 1
Can be opened on both sides around each position P like a folding screen. In addition, suspension rings 3 and 3 are installed on both sides of the joint between the blocks so that they can be lifted by the claws of the crane.

[0007] The series of resin foam blocks 1 thus joined together can be lifted up by a heavy machine, and as shown in FIG. Etc.

An advantage of using such a resin foam block 1 is that the resin foam block is extremely lightweight, so that workability in laying and removing is good.

Since the embankment load can be reduced as compared with the embankment method, the subsidence of the foundation ground can be reduced. Since the resin foam block has the self-supporting property, the lateral pressure can be reduced as compared with the case of embankment, so that the slope or the like is less likely to collapse and the existing structure is less affected.
And the like.

[0010]

By the way, when such a resin foam block 1 is laid, each block 1a is surrounded by a net 2, so that a large amount of net is required as a whole. As a result, there is a problem that the cost becomes high in terms of cost. Further, in the case where the resin foam blocks 1 are continuously connected in this way, a large number of resin foam blocks 1 can be laid at one time, but it is necessary to always carry them as a unit, so that the work efficiency becomes poor in transportation or management. There is also. In addition, when trying to open these joined pieces on both sides due to the muddy condition, there was a case where the resistance increased and it was not possible to open them well. Further, for example, if a five-row type is used on site, in some cases, an unused fraction remains at the end, and as a result, one or two must be separated and used.

In view of the above situation, the present invention is a temporary floor surface that can be manufactured at low cost, does not cause waste during construction, and can efficiently construct a temporary floor surface. It is intended to provide a building method.

[0012]

In order to achieve the above object, a method for constructing a temporary floor surface according to the present invention is such that a strip-shaped body is wound around a resin foam block having a substantially rectangular parallelepiped shape, and the strip-shaped body is wound. It is characterized in that the rotated resin foam blocks are placed adjacent to each other, and the adjacent resin foam blocks are connected to each other by a locking tool or another strip.

Here, the number of strips wound around the resin foam is three in a direction crossing the long side of the resin foam block at a right angle and in the direction crossing a short side at right angles. 1
It is a book, and it is preferable to divide the long side into four and the short side into two with these strips.

[0014]

According to the present invention having the above-mentioned structure, the strips are wound around the resin foam block in advance, and the strips are wound when the resin foam block is laid in a predetermined range. Match the parts. After the resin foam block has been laid in the predetermined range in this way, the other strips or the fasteners may then be used to tie the strips together.

In this way, if a plurality of resin foam blocks are connected to each other, only the necessary parts need to be connected, so that a large amount of nets or the like is not necessary for integration. In addition, it is possible to fix the entire plurality of resin foam blocks as one aggregate with a minimum amount of material.

Moreover, since such a strip is wound in advance, the resin foam block 1 is convenient to carry. Further, in the case of removal, it suffices to cut the connecting belt-like body or detach the locking tool, and the removal work is simple.

If three strips are wound in the direction crossing the long side and one strip is wound in the direction crossing the short side as described above,
When these resin foam blocks are stacked in a zigzag pattern, the strips of the resin foam blocks located above and below come into contact with each other, so it is possible to freely assemble them in various directions. it can.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a method of constructing a temporary floor surface according to an embodiment of the present invention, and particularly show an example of application to soft ground.

In this embodiment, the resin foam block 1 made of styrene foam or the like having a substantially rectangular parallelepiped shape is used. Bands 2 made of polypropylene or the like are wound around the resin foam block 1 in a cross shape. Since such a resin foam block 1 is placed on the soft ground P to form a flat floor surface, it is preferable that the resin foam block 1 has a rectangular shape having upper and lower flat surfaces. The wall thickness is 50c.
It may be about m.

In the soft ground P, for example, first, the first row of resin foam blocks 1, 1, 1 are laid along the existing road R. In this way, after the first resin foam blocks 1 are lined up, the second row resin foam blocks 3, 3, ... 3 are laid.

In this way, the resin foam blocks 1, 3, 4, 5 etc. are laid in sequence within a predetermined range. When these resin foam blocks 1, 3, 4, 5 are laid, one resin foam block and the band wound around the adjacent resin foam block are adjacent to each other. For example, they are connected by a clip-shaped locking tool 7 as shown in an enlarged manner in FIG. The locking member 7 is formed in a U shape having a closed end 7a by a pair of plate materials, and these are formed of an elastic material such as synthetic resin or metal.

A notch 8 is formed in one plate member 7b of the lock 7. Using such a locking tool 7, for example, it is inserted at the position A shown in FIG.

As described above, when the resin foam blocks arranged in the outermost peripheral region are mounted between the resin foam blocks, the resin foam blocks located inside are inevitably immovable. As a result, the resin foam blocks arranged vertically and horizontally can be fixed as one aggregate. The shape of the locking tool used in this way is not limited to the embodiment. For example, as shown in FIG. 4, the slit 9 is formed in the center of the flat plate.
The locking tool 9 provided with a may be used. Further, the part to which the locking tool 7 or 9 is attached is not limited to the embodiment,
The number of connecting points can be increased if necessary.

If a reinforcing iron plate or the like is further arranged on the resin foam blocks that are arranged in a number of rows using such a locking tool, a construction vehicle, such as a backhoe or a large crane truck, etc. It can also be run to work.

Furthermore, after constructing such a temporary floor surface, if the locking tool 7 is removed, these resin foam blocks 1, 3, 4, 5 etc. can be easily removed one by one. it can. In addition, in the above embodiment, an example of fixing between the resin foam blocks adjacent to each other by using the clip-shaped locking tool has been described, but instead of this, another short band is prepared, and the block is used by You may make it fix mutually.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the band 2 is fixed to the upper and lower sides of one side of each resin foam block 10 by sandwiching the contact plates 11 having an L-shaped cross section in advance. The position of the backing plate 11 is not limited to two positions on one side as shown in the drawing, but may be provided at a total of four positions on both sides.

By preparing a plurality of resin foam blocks 10 provided with such contact plates 11 and arranging these contact plates 11 vertically and horizontally in a straight line, the strength of the corners is increased. Can be made.

Also in this embodiment, at least the resin foam blocks adjacent to each other located at least in the outermost peripheral region are connected to each other by a fastener or another band. FIG. 6 shows a third embodiment of the present invention.
In this embodiment, two bands 13 for running the band are formed in the direction crossing the long side of the resin foam block 12, and one in the direction crossing the short side. These grooves 1
3 is continuously formed over the entire circumference of the resin foam block 12.

If such grooves 13 are formed in the resin foam block 12, these strips will not protrude from the outer surface, for example, even if a thick band or a rope is used. Absent. Therefore, it can be preferably used especially in a place of use having flatness.

FIG. 7 shows a resin foam block 14 used in the fourth embodiment. The resin foam block 14 of this embodiment has a size of 100 × 50 × 200 mm, and three bands 2 are arranged in a direction in which their long sides are orthogonal to each other.
Is wound. Further, one band 2 is wound in the direction in which the short sides are orthogonal. As a result, the band is wound around the long side and the short side of the resin foam block 14 at positions divided into four and two.

By thus winding the three bands 1 and the band 2 respectively, the resin foam block 1
As shown in FIG. 8, it is easy to connect adjacent blocks to each other when the blocks 4 are arranged in the vertical direction.

That is, when the upper resin foam 14 is arranged so as to straddle the two lower resin foams 14, 14,
Since the upper and lower bands 2 and 2 are in contact with each other, the upper and lower resin foam blocks 14 and 14 can be immovably fixed at this position C by using another short band or the like. If an iron plate or the like is placed on this, a heavy machine such as a crane truck can be run as in the above-described embodiment.

Further, by winding the three and one bands as described above, the resin foam block 14 can be freely moved in multiple stages or in the horizontal direction as shown in the top view of FIG. Can be combined in any direction. For example, in FIG. 9, four resin foam blocks 14 are arranged in the same direction in the first row, but one resin foam block 14 ′ is straddled on three resin foam blocks 14 among them. Have been placed. At this time, the three bands 2 of the second-stage resin foam block 14 ′ come into contact with the band 2 wound around the lower resin foam block 14. Therefore, by connecting these to each other, the upper and lower two stages of the resin foam blocks 14 can be fixed immovably. Further, even when the other resin foam blocks 14 ″ are laid in a posture rotated by 90 degrees with respect to the four resin foam blocks 14 arranged in the same posture in the first stage, the bands 2 are connected to each other. be able to.

Although the respective embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example,
In the above embodiment, the case where the resin foam block is used as the floor surface of the soft ground or the temporary road has been described, but the construction method of the present invention is not limited to the field of civil engineering, and for example, a stage for temporary construction or a temporary competition. It can be applied to a floor-like surface. The size of the resin foam block for embankment may be 425 × 183 × 925.5 mm, but is not limited thereto.

[0035]

As described above, according to the method for constructing the temporary floor surface according to the present invention, the resin foam blocks are formed as a single body and are not connected to each other. Therefore, one or two resin foam blocks do not remain at the end. Moreover,
At the time of connection, since only a necessary portion is connected using a fixing tool or a band-shaped body such as a band, workability is also easy.

When connecting with a band-shaped body such as a band,
By winding three wires so as to traverse the longitudinal direction and one wire so as to traverse the lateral direction, the resin foam blocks can be freely combined and connected.
