DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the, L-type block having a bottom plate constituting the primarily retaining wall (inverted T-type), box culverts, or for the installation structure of the precast concrete products of the U-shaped block.

[0002]

2. Description of the Related Art An L-shaped block constituting a retaining wall is installed as follows.
Recently, for example, Japanese Utility Model No. 57-20673, Japanese Utility Model No. 7
As shown in JP-B-133616 and Japanese Utility Model Laid-Open No. 7-42381, a female screw member is integrally formed at a plurality of locations of a bottom plate of an L-shaped retaining wall block, and height and horizontal adjustment are performed by adjusting bolts screwed into the female screw member. Something that is going to be done is suggested. Such a structure has also been proposed in U-shaped blocks and box culverts (for example,
23939).

[0003]

The above-described structure for adjusting the height and level of a conventional precast concrete product having a bottom plate has been used since the production of a precast concrete product having a bottom plate. Accordingly, it is necessary to embed a plurality of female screw members correspondingly, so that a manufacturing method different from a normal product, a member such as an insert metal fitting, and a trouble such as an arrangement thereof are required. In particular, the normal standardized bottom
There was much waste in manufacturing and storing a precast concrete product different from a precast concrete product having a plate .

[0004]

Therefore SUMMARY OF THE INVENTION In the present invention, conventional L-type block having a bottom plate having no height adjustment feature, when box culverts, or installing the precast concrete products of the U-block, the bottom plate Yes
A steel material having a bolt screw hole which is maintained at a predetermined interval with a space maintaining material is installed on an installation seat where a precast concrete product to be arranged is to be installed, and a precast concrete product is installed by a height adjusting bolt screwed into the bolt screw hole. Bottom
While the plate was supported, concrete was poured from a concrete pouring hole provided in the bottom plate, or a precast concrete product installation structure having a bottom plate integrated by pouring concrete from the side was adopted. A steel material as a support material for the height adjusting bolt is preferably an angle material in terms of strength, and it is preferable to maintain a predetermined interval between two substantially parallel steel materials with a spacing material.

[0005] In addition, a bottom plate having no height adjusting function is provided.
That normal L-type blocks, box culverts, or when installing the precast concrete products of the U-block to form a seating mount panel to place the precast concrete products with the bottom plate with cast-in-place concrete or precast mounting plate, the installation Install insert materials with bolt screw holes at predetermined intervals with respect to the seat panel,
While the bottom plate of the precast concrete product is supported by the height adjustment bolt screwed into the bolt screw hole, concrete is poured from the concrete casting hole provided in the bottom plate, or concrete is poured from the side surface and integrated. I did it.

[0006] Furthermore, a bottom plate having no height adjusting function is provided.
Normal L-type blocks, box culverts that, or when installing the precast concrete products of the U-block, partially established the precast mounting plate installation seat placing the precast concrete products with the bottom plate, on the mounting plate On the other hand, insert materials having bolt screw holes are installed at predetermined intervals, and the height adjustment bolts screwed into the bolt screw holes are used for precast concrete products .
Concrete was poured from a concrete pouring hole provided in the bottom plate while the bottom plate was supported, or concrete was poured from the side to be integrated.

The present invention is most suitable for the installation of an L-type (inverted T-type) block having a concrete casting hole in the bottom slab constituting the retaining wall as described above. It can be applied to the installation of a precast concrete product having a U-shaped block or a box culvert bottom plate .

[0008]

FIG. 1 is a perspective view showing a first embodiment of the present invention, and FIG. 2 is a perspective view showing a state of maintaining a parallel angle member. In the L-shaped retaining wall block 1 shown in this example, a concrete casting hole 3 is provided in a bottom plate 2, and a reinforcing bar 4 in the bottom plate 2 is exposed in the concrete casting hole 3. This type of L-shaped retaining wall block 1 is not limited to the present invention, and can be used for ordinary direct installation work. Insert when installing the precast concrete products with such bottom plate, in the first embodiment of the present invention, with respect to the installation seat 10 obtained by solidifying smoothed out ground to place the precast concrete products, with a bolt screwed holes The two substantially parallel angled members 6 having the number 5 are installed in a state where they are maintained at predetermined intervals by the interval maintaining material 7 of the reinforcing bar, and the height adjusting bolt 8 is screwed into the bolt screw hole of the insert 5. The L-shaped retaining wall block 1 of the precast concrete product is supported by vertically adjusting. In this state, concrete is cast from the concrete casting hole 3 provided in the bottom plate 2 of the L-shaped retaining wall block 1 and integrated.

FIG. 3 shows another example of a structure in which the angle members 6 and 6 are maintained at a predetermined distance by a distance maintaining member 7. The spacing member 7 is a steel strip in this example. The insert 5 having a bolt screw hole is welded to the angle member 6.

FIG. 4 shows an example in which an insert 5 having a bolt screw hole is implanted in an installation seat panel 11 on an installation seat on which the L-shaped retaining wall block 1 is mounted. The bottom plate of the L-shaped retaining wall block 1 of the precast concrete product is supported by screwing the bolt 8 up and down. An installation seat panel 11 is provided with a protruding safety bar and anchor bar 12, and the L-shaped retaining wall block 1 is provided.
A safety / anchor bar 13 is also provided at the bottom of the boss.

FIGS. 5 and 6 show various types of the installation seat panel 11. In the example of FIG. 5, the installation seat panel 11 on the right side is a flat plate, and the insert 5 is implanted in this,
Furthermore, the height adjustment bolt 8 is screwed in to adjust the height up and down. FIG. 6 shows a side view. Bottom plate on adjustment bolt 8
A precast concrete block having Reinforcing bars 4 in the bottom plate 2 are exposed in the concrete casting hole 3. Concrete is cast from the concrete casting hole 3 and integrated with the installation seat. The seat is made of rough concrete.

The installation seat panel 11 shown on the left in the example of FIG.
Is a beam type, and a side view thereof is shown in FIG. Both ends protrude. This is an example in which an insert is implanted in this protruding portion. The L-shaped retaining wall block of the precast concrete product is supported by screwing a height adjusting bolt 8 into a bolt screw-in hole to adjust the height up and down. I have.

In the example shown in FIG. 8, the installation seat panel 11 is divided by a screw adjustment portion of the height adjustment bolt 8. An insert 5 having a bolt screw hole is implanted in each block. The installation seat panel 11 can be buried and used at the same time when adjusting the installation seat.

[0014]

According to the present invention, a normal (general-purpose) bottom plate can be used.
It has become able to height and horizontal adjustments easily applying a installation of precast concrete products having. This allows
It is no longer necessary to specially manufacture a height-adjustable L-type (inverted T-type) block or the like. Therefore, low-cost construction was made possible.
