Description

  The present invention relates to an L-shaped concrete block for retaining walls (hereinafter referred to as an L-shaped block for retaining walls) used in the construction of retaining walls such as boundary walls for residential land development and road shoulders.

  Conventional retaining wall blocks can be divided into a right-angled L shape and an obtuse angle of 105 degrees L-shaped when divided by the longitudinal cross-sectional shape. When a retaining wall is constructed using the retaining wall L-shaped block, it is shown in FIG. The concrete is driven into the foundation concrete 22, the concrete foundation members 24 formed thereon are sequentially laid, and the retaining wall blocks 23 are sequentially installed and fixed on the concrete foundation members 24. After that, the construction method was to embed the bottom of the concrete foundation member and retaining wall block under the ground surface.

  In this case, there are large and small L-shaped blocks for retaining walls, but even normal ones have a weight of 1 ton and a height of 2 m, and the installation work at the normal position is inefficient, so it is lightweight, small and workable A good foundation member is used, and the foundation surface is first constructed by laying the foundation member horizontally. Accordingly, if the foundation member is not accurately installed, it is impossible to stabilize the retaining wall block and accurately install it in a fixed position to construct a rigid retaining wall.

  The retaining wall L-shaped block has a cross-sectional shape of an obtuse angle of 105 degrees in order to reduce or prevent the phenomenon of sliding, tilting, sinking, etc., and as shown in FIG. 2. Since the bottom plate portion 4 and the support portion 6 are inclined by 15 degrees from the horizontal, the connecting position of the bottom plate portion 4 is usually higher than the vertical wall bottom surface 3 as illustrated in the accompanying drawings. In the construction, the installation position and angle are determined only by the vertical wall bottom surface 3 in contact with the base member, and the work at the time of installation is inefficient and unstable.

  For construction of retaining wall construction using retaining wall L-shaped block, it is popular to use foundation members. However, since conventional foundation members have a simple cross-sectional square or substantially trapezoidal pentagon, It was not a structure and shape intended for fixing to the base surface, connecting to adjacent base members on both sides, fixing, connecting to the retaining wall block to be placed, and fixing, but merely a mounting table.

  As shown in FIGS. 1 and 2, the retaining wall L-shaped block 1 includes a vertical wall portion 2 and a bottom plate portion 4 that is inclined 15 degrees from the horizontal. The vertical wall portion 2 and the bottom plate portion 4 have an obtuse angle of 105 degrees. The vertical wall portion 2 and the bottom plate portion 4 are supported by the support portion 6. The bottom plate portion 4 is usually provided with a plurality of through holes 5 for filling concrete so that the bottom surface of the bottom plate portion 4 can be easily filled with concrete. The vertical wall bottom surface 3 of the vertical wall portion 2 is fitted with various foundation member side fitting structures provided on the upper surface of the foundation member 7 so as to be fitted and exposed. Provide structure.

  There are various L-con fitting structures provided on the bottom of the vertical wall of the retaining wall L-shaped block of the present invention. FIG. 1 shows an embodiment in which a trapezoidal L-shaped projection 8 having a trapezoidal cross section is provided on the bottom 3 of the vertical wall. FIG. 2 shows an L-cone longitudinal groove 9 having a triangular cross-section on the bottom surface 3 of the vertical wall, and a longitudinal projection 11 having a triangular cross-section that fits into the L-cone longitudinal groove 9 is projected on the upper surface of the base member 7. An example is shown.

    In order to construct a retaining wall using the retaining wall L-shaped block, the front and rear, left, right, and upper and lower directions of the retaining wall L-shaped block are adjusted in order and aligned during construction. It is necessary to prevent settling and overturning movements. For this reason, when installing directly on the foundation concrete, the foundation part comprising the foundation member is aligned in all directions when using the foundation concrete and the foundation member. It is important to build horizontally and fix it on top of it, but the structure and shape of the conventional retaining wall L-shaped block and foundation member are both easily aligned and connected in all directions, It did not have an effect that can be firmly fixed.

  The retaining wall L-shaped block according to the present invention works in correspondence with the base portion provided with a fitting structure that interfits with the fitting structure of the vertical wall bottom surface, and causes phenomena such as sliding, tilting, settling, and falling. It is to reduce and prevent, and has a structure and shape with conditions for installation, connection and fixation to a foundation part composed of a foundation concrete surface or a laying surface of a foundation member.

  Regarding the connection and fixing of the retaining wall L-shaped block 1 according to the present invention, as shown in the attached drawings, the L-con long projection 8, the L-con long groove 9, and the L-con connection projection 12 provided on the vertical wall bottom surface 3. , L-con connecting hole 13, L-con horizontal projection 16, L-con horizontal groove 18, L-con step 20, base portion longitudinal groove 10 provided on the upper surface of base portion 7, base portion longitudinal projection 11, foundation This is performed by fitting the part connecting hole 14, the base part connecting protrusion 15, the base part horizontal groove 17, the base part horizontal protrusion 19, and the base part step 21.

  The present invention relates to an L-shaped block for retaining walls used when constructing a retaining wall construction, and when installing the retaining wall L-shaped block at the time of construction, a base portion whose position and direction are already aligned and fixed. Since it is installed, fitted and fixed on the top, installation positioning and alignment become extremely easy and can be easily connected and firmly fixed. This means that the base member is easier to handle and easier to install than the retaining wall block, which has a large weight and size. After that, the construction method of installing the retaining wall L-shaped block according to the present invention on the foundation member is adopted, so that the retaining wall L-shaped block having a large weight and size is moved greatly. The installation position can be determined by just fine adjustments without adjusting the position, making it easy to accurately align and connect with the adjacent retaining wall L-shaped block, greatly reducing installation work. It is extremely effective in improving the construction efficiency of retaining wall construction.

  The L-shaped block for retaining wall according to the present invention is characterized in that an L-con fitting structure is provided in the longitudinal direction of the bottom surface of the vertical wall to match and fit in accordance with the foundation fitting structure provided on the upper surface of the foundation portion. The L-con fitting structure is configured to correspond to conditions such as the size of the retaining wall construction, the situation at the site, the dimensions of the retaining wall L-shaped block to be used, and the type of the foundation part to be used. Therefore, the base part longitudinal groove and the base part longitudinal protrusion provided on the upper surface of the base part, the base part connection hole, the base part connection protrusion, the base part horizontal groove, the base part horizontal protrusion, the base part continuous in the longitudinal direction. L-con long protrusions, L-con long grooves, L-con connection protrusions, L-con connection holes, L-con horizontal protrusions, L-con horizontal protrusions, which are respectively fitted according to the basic fitting structure such as steps. A groove and an L-con step are provided. A rigid retaining wall can be constructed by combining the L-shaped block for retaining walls with the L-con fitting structure on the bottom of the vertical wall and the foundation with the foundation fitting structure on the top. The construction efficiency of wall construction can be remarkably improved.
