Abstract

PURPOSE: To dispense with the processing work for the decoration of a retaining wall surface after the establishment of the retaining wall, significantly shorten the construction period, and improve the workability. CONSTITUTION: A retaining wall form which was assembled in a constructing side in the past is preliminarily formed as a frame strut 11 for supporting a frame strut 11 at a prescribed inclination, and supported by and fixed to a support foundation 2 set in a constructing site to form a frame. Panel blocks 3 having surfaces subjected to a prescribed work are laid on the frame strut 11, juxtaposed and fixed, whereby a retaining wall frame is constituted, and concrete is filled in the retaining wall frame.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a wall processing retaining wall in which the surface of the retaining wall is embedded with natural stones, chipping decoration, pattern processing such as mosaic painting, and a panel block used therefor. .

[0002]

2. Description of the Related Art In recent years, with respect to retaining walls constructed for retaining soil on sloping ground, it has been required to construct a retaining wall that not only protects the sloping ground but also harmonizes with the surrounding landscape. It is generally performed to embed natural stone or the like on the retaining wall, or to pattern the retaining wall.

[0003] In the case of constructing such a retaining wall, conventionally, after the in-situ retaining wall has been constructed, stones or the like are fitted or adhered, or a mold such as Styrofoam is covered from the outside of the retaining wall, and concrete is interposed between them. It was used to make a pattern by pouring.

[0004]

However, it is inefficient to work after the retaining wall has been built, resulting in an increase in the construction period.

In addition, when a stone is attached to the retaining wall, the stone and the retaining wall are often not completely integrated with each other, and the stone may fall, which is dangerous.

On the other hand, in the method of forming a pattern using a mold such as Styrofoam, concrete flows out from a gap, the mold comes off during work, and conversely the Styrofoam does not come off easily after placing concrete. There was a problem and the workability was poor. In addition, there is also a problem of converting styrofoam after demolding to industrial waste and its treatment.

SUMMARY OF THE INVENTION The present invention addresses the above-mentioned problems, in which a gantry frame for supporting a gantry support is formed in advance at a predetermined inclination and is supported and fixed to a support foundation set on site. In addition to forming the pedestal, the panel block with the surface processed to hang it on the pedestal column is installed and fixed in parallel to form the retaining wall frame, and the retaining wall frame is filled with concrete. It is a thing.

[0008]

According to the present invention, the retaining wall formwork, which is conventionally assembled and formed on site, is preliminarily formed as a gantry frame for supporting the gantry support at a predetermined inclination, and is supported and fixed to a supporting foundation set on site, which is extremely quick. The framework of the retaining wall form is formed on.

Further, a block whose surface has been subjected to a predetermined process in a factory or the like is used as a panel block, and the panel block is hung from a supporting column supported and fixed to a supporting foundation set on the site and fixed in parallel, so that the frame remains as it is. By incorporating it into the body structure, it became possible to create a wall processing retaining wall at once.

Further, on the rear surface of the panel block, an insert bush having an internal thread engraved on the inner wall is set in advance in the frame of the panel block and embedded therein, whereby L
Attached items such as mold anchor bolts can be easily screwed.

According to the present invention, which is configured as described above,
The wall surface processing is formed integrally with the retaining wall construction, and the imperfections regarding the integration of the decoration processing and the retaining wall are corrected.

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a gantry frame, which is preliminarily formed by the support columns 12 so as to support the gantry columns 11 at a predetermined inclination.
Are welded and fixed to the support base 2 to form a pedestal.

The support base 2 is a pedestal base fixed bar 21 which is set to be embedded by exposing the head on the leveled concrete surface A,
One edge is made up of an embedded angle 22 set to be embedded in leveled concrete, and the head of the pedestal foundation fixing bar 21, the pedestal foundation 13, and the embedded angle 22 and the gantry front end 14 are welded and fixed.

The gantry frame 1 is integrally formed as shown in FIG. 1 according to the setting environment of the retaining wall construction site.
15 may be set, or as shown in Fig. 2, the structure is such that the reinforcement is added step by step. First, the foundation is set and concrete filling finish is performed, and then the support foundation 2 is further set on the top and piled up. You may choose to go.

Reference numeral 3 is a panel block that forms the exterior of a retaining wall, and the panel surface is pre-cast to have a pattern B that is in harmony with the surrounding landscape and a process B such as embedding natural stone, and is produced in advance in a factory. is there.

On the back surface of the panel block 3, an insert bush 31 having a female screw engraved on the inner wall is embedded so that an attachment such as an L-shaped anchor bolt 32 can be easily screwed.

In the embodiment shown in FIG. 1, the pedestal foundation fixing bars set at predetermined intervals along the width of the panel block 3
21 head and pedestal foundation 13, embedded angle 22 and gantry front end
14, the embedded angle 22 at the rear part and the rear end 16 of the gantry are welded and fixed, and when the gantry frame 1 is installed in parallel, the gantry columns 11 and 15
The panel blocks 3 are hung on each of them to be stacked and fixed in parallel to form a retaining wall frame, and the frame is filled with concrete.

For stacking the panel blocks 3 on the gantry columns 11 and 15, the bolt insertion holes 17 provided on the gantry columns 11 and 15 are aligned with the female screw holes 33 on the rear surface of the panel block 3, and the bolt insertion holes 17 are used to connect L The mold anchor bolts 32 are screwed together, and the nuts 34 and washers 35 are tightened to the gantry support.

For the embodiment shown in FIG.
21 head and pedestal foundation 13, embedded angle 22 and gantry front end
14 is welded and fixed, and the gantry frame 1 in the lower stage is installed in parallel, and a panel 37 for a conventional cast-in-place mold is set with a spacer 37 at the rear part.

By installing the gantry frame 1 in the lower stage in parallel, the panel blocks 3 are hung on the gantry columns 11 as described above, piled up and fixed in parallel, and the panel block 3 and the panel 36 for the in-situ casting frame 36 are used as retaining walls. Construct a frame and fill the frame with concrete.

Therefore, the supporting base 2 is further set on the top of the lower retaining wall formed by the lower frame to set the supporting frame 1 in parallel, the panel block 3 is hung, and the panel 36 is set. The upper retaining wall is piled up by filling with concrete.

In this embodiment, the concrete is placed in two steps. Therefore, the parallel installation of the gantry frame 1 is divided into two stages, but the parallel installation of the gantry frame 1 is divided into several times. Whether or not it is decided considering the size of the retaining wall to be constructed and the ease of work.

With the above construction, the angle assembly can be made smaller and lighter in the present embodiment, so that it is possible to preassemble the angle assembly and transport it to the site, and as a result, the site work is remarkably simplified. Can be converted.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it is not necessary to carry out work on the landscape after building the retaining wall, the construction period can be greatly shortened, and the workability is improved.

That is, since the stone-clad panel can be pre-casted to give aesthetic consideration in advance, it is not necessary to finish after the retaining wall has been built, and the stone-clad panel can be processed more delicately than on site.
