Description

Retaining wall block capable of tilt adjustment and block retaining wall having same {RETAINING WALL BLOCK CAPABLE OF ADJUSTING SLOPE AND BLOCK TYPE RETAINING WALL WITH THE SAME}

The present invention relates to a retaining wall. More specifically, in a block type retaining wall that forms a retaining wall by stacking segments using its own weight, a gravity type capable of inclined adjustment capable of elastically adjusting the gradient of the retaining wall according to site conditions A retaining wall block and a retaining wall having the same.

A retaining wall refers to a structure installed at the edge of a mountain road or the like to prevent soil from falling down. Conventionally, the retaining wall has been used in the field pouring method to install the plywood formwork on the foundation after the foundation, as the construction of the concrete wall in step by step according to the height.

However, since the field casting method is installed at the work site, a lot of time must be passed while the retaining wall is installed and the concrete is hardened to serve as the retaining wall, as well as a lot of time for installing and dismantling the formwork and assembling the reinforcing bars. There was an issue that took place. For this reason, recently, a prefabricated retaining wall has been used in which a retaining wall, which has been cured in advance in a manufacturing workshop or a factory, is moved to a work site, and then simply assembled and installed at a site.

One such prefabricated retaining wall is a block retaining wall that can provide a beautiful appearance. The block retaining wall is configured to form the retaining wall by stacking the blocks using its own weight.

9 is a cross-sectional view showing a conventional block retaining wall. Referring to FIG. 9, a conventional block retaining wall uses a shear key as a means for resisting soil pressure, and the shear keys 1b, 2b, and 3b are integrally formed with the block bodies 1a, 2a, and 3a as shown in FIG. It is common to manufacture or to be manufactured in a single inclined type in which the inclination is fixed in advance as in the prior patent 1, and thus there was a disadvantage that it is impossible to adjust the retaining wall in accordance with the site conditions.

For example, assume that the block retaining wall of FIG. 9 is constructed by stacking retaining wall blocks to have an inclination A. FIG. In this case, each retaining wall block (1, 2, 3) of Figure 9 is formed with a shear key (1b, 2b, 3b) to be stacked in an inclined A structure. By the way, the conventional retaining wall block (1, 2, 3) is fixed to the position and shape of the shear key bar, as shown in Figure 9 when you want to give a gradient to the block-type retaining wall is constructed at an inclination A, corresponding to the gradient Another type of retaining wall block with shear keys was needed.

In other words, the conventional block-type retaining wall has been determined and fixed at the time of production of the product, the gradient change was not possible according to the site conditions.Inevitably, to control the gradient, another type of retaining wall block is produced by remanufacturing a separate mold. There was a limit to construction.

After all, in the case of the conventional block retaining wall, the producer had to manufacture and equip each of the various molds according to various inclinations, and then produce and supply the retaining wall blocks suitable for the buyer's request.

Accordingly, the cost of the product is increased due to the retention of a large number of formwork, and a number of products must be manufactured according to various specifications. Therefore, there is a limit in the amount of products produced in advance, which may cause difficulty in securing inventory. there was.

It may be determined based on the 2, N shear plane. In this case, the maximum width of the reference to the first shear surface 23a corresponds to the maximum distance from the fixing part 13 to the first shear surface 23a, and the maximum width of the reference to the second shear surface 23b is high. It corresponds to the distance to the second shear surface 23b on the basis of the government 13, and the maximum width of the Nth shear surface reference corresponds to the distance to the Nth shear surface on the basis of the fixing part 13, and again Each of the maximum widths of the first, second, and N shear planes is formed to have a different length from each other.

Although the preferred embodiments of the present invention have been described and illustrated using specific terms, such terms are only for clarity of the present invention, and the embodiments and the described terms of the present invention are defined and the technical spirit and scope of the following claims. It is obvious that various changes and modifications can be made without departing from the scope of the invention.

For example, in the case of the embodiment according to Figures 1 to 6, the fixing portion 13 is composed of a recess structure, the coupling portion 25 is described in the form of a column inserted and coupled to the fixing portion 13 of the recess structure. Although shown, on the contrary, the fixing part 13 is configured in the form of a column, and the coupling part 25 may achieve the same purpose even when the fixing part 13 is formed in the groove structure into which the fixing part 13 is inserted and coupled. Of course.

Such modified embodiments should not be understood individually from the spirit and scope of the present invention, but should fall within the claims of the present invention.
