Description

Block for breast wall {Block for breast wall}

The present invention relates to a retaining wall block, and more particularly, to improve the construction structure of a retaining wall block for building a slope on a dike, breakwater, shelter, road, etc. to allow a variety of block construction methods, as well as a quick period. It is intended to be structurally stable while being able to build inside.

In general, the retaining wall is constructed for the purpose of collapse of the inclined slope and protection from the outside. The retaining wall is generally made of stone and concrete uniformly, and the retaining wall is completed through a multi-stage work process that is alternately constructed in the transverse direction.

Existing retaining walls have various forms such as concrete retaining walls and stone slabs. However, due to structural problems, there are problems such as limiting the height of retaining walls, aesthetic problems, site utilization, and long construction periods. Is being studied. Among them, the construction of reinforced earth retaining wall is increasing in that the block-type reinforced earth retaining wall has the most structural stability, environmentally friendly aesthetics, and the retaining wall can be built in a short period of time.

Blocks resulting from the construction of retaining walls have been presented in US Pat. No. 4,299,123 and US Pat. No. 4,525,331, which disclose a number of blocks stacked side by side to form a retaining wall.

The blocks generally have a structure of tongues and grooves that allow the rows of adjacent blocks to join each other to form an upstanding wall, and a structure having an inner hole that is open at the top and bottom to accommodate soil and vegetation.

However, the block is expensive because it is manufactured using a considerable amount of material, and the construction of the retaining wall requires a considerable time and labor to avoid the production and work of the block.

In addition, the retaining wall block described in Korean Patent Publication No. 97-1721 has a front face 17, an upper face 42, and a bottom face 46 having opposite ends, as shown in FIGS. And a body portion 13 comprising side walls 18, 19 extending rearward from opposite ends of the front face 17, the body portion 13 also having the top surface 42 and the bottom. A first pin hole 39 for receiving a first pocket 43 and a second pocket 44 and a pin 51 which are open to one of the sides 46 and spaced from the side walls 18 and 19. And a block interconnection means having a second pin hole 41, wherein the first pin hole 39 is disposed adjacent the first pocket 43 and is laterally shifted from the first pocket 43. The two pin holes 41 are arranged adjacent to the second pocket 44 and are arranged to be shifted laterally from the second pocket 44.

In the construction of the blocks, the blocks are arranged in rows in a row from an inclined bank, and in forming another block in rows in an upper side between the arranged blocks, the pocket portion corresponding to the upper surface side of the blocks arranged in one row is located on the upper side thereof. The pins inserted into the pinholes of the blocks superimposed on each other can be constructed in a guided manner, and the pocket has an arch shape, so that a block formed by starting the guide pins can be arched.

However, in the structure of the block structure, when the block shape of the block is formed in a straight line, the block is formed to be arched roundly along the curved surface of the masonry and the topographical conditions. Or vice versa), but the pocket always has a free space in the state of structuring like the first time due to crustal fluctuations, so that the block may be out of the original masonry position, and the pinhole penetrates the block to prevent stress. It is concentrated and causes the crack of the block, which has the problem of unexpected collapse and accident risk.

In addition, the block using the pin method can be inclined wall, but when trying to form a round corner in the inclined section, the block is fixed to the pin and the socket, so that the horizontal movement is impossible to remove the pin or cut the air supply block in half There was a problem of poor workability, such as construction and failure to implement the stability of the retaining wall.

Meanwhile, another conventional block construction method is disclosed in US Pat. No. 4,920,712.

As shown in Figures 5 and 6 attached to the first block in the horizontal direction to form a predetermined interval, and the upper layer block is installed between the blocks on the upper layer, the block 12 is the front Protruding jaws 30 and 32 are formed on the left and right sides having rough surfaces at 18 and 20 and abutting the rear surface 22 along side surfaces 26 and 28 having a predetermined inclination angle from the front surfaces 18 and 20 to the rear surfaces. On both sides of the upper surface 38 of the rear surface 22, support grooves 40 and 42 recessed to a predetermined depth with a predetermined width are formed, and the upper surface of the support grooves 40 and 42 from the one side of the front side in the front side direction. The bottom surface and the through-holes 34 and 36 penetrated are formed, the support grooves 40 and 42 are provided with a clip 44 having a h-shape for supporting the block to be stacked in the upper layer.

The h-shaped clip 44 has a vertical portion 48 to be tightly supported on the upper side of the rear surface 22 of the block, and is bent at a right angle from the vertical portion 48 to support the upper surfaces of the support grooves 40 and 42. The horizontal portion 46 is formed to be guided to, and vertically integrally formed on one side of the horizontal portion 46 vertically lower portion 50 to be in close contact with the upper portion of the through hole (34, 36), formed to extend to the upper side of the vertical lower portion And a vertical upper portion 52 for supporting the inner bottom surface of the through hole of the block located in the upper layer.

The clip 44 is one side of the through holes 34 and 36 of the block located in the upper layer, that is, the inside of the through hole located in the rear surface 22 in the range that can flow left and right with respect to the width of the support grooves 40 and 42. Protruding jaw (60) having a predetermined inclination angle at the bottom portion is integrally formed.

One end of the protruding jaw 60 formed at the bottom of the block is attached to the upper layer of the clip in a form that is closely supported on the vertical upper portion 52 of the clip 44, as shown in FIG. I can support it. Blocks constructed by using the clip in this way is the block is stacked with a step toward the upper layer as the protrusion of the protruding jaw 60 with respect to the block of the lowermost layer.

However, as the block state of the block has a range in which the clip guided and installed to the support groove can be flowed from the width space of the support groove, the work time must be adjusted while accurately positioning the block when the block is tightened. There is a problem that takes a long time, there was a lot of difficulty in dealing with a relatively heavy block because the clip is unstable until the block is seated in the upper layer.

In addition, since the part connecting the block and the grid for reinforcement is located at the back of the block, that is, where the h-shaped clip is installed, the binding of the block and the grid is unstable and the front of the block is distorted and the grid is easily broken away. Is concerned, and the construction is very poor because only masonry is required to break out the protrusions 30 and 32 as shown in FIG. 5B when the block is installed in the inner curved portion, and as shown in FIG. 5A, Clips 44 and the through holes 34 and 36 of the blocks positioned on the upper layer of the assembled block have no problem at all due to the lack of binding.

The present invention has been made to solve all the problems of the block according to the formation of the retaining wall as described above, the block is vertically or inclined in accordance with the direction of the h-shaped clip applied to the block to the retaining wall block applied to the block It is an object of the present invention to provide a retaining wall block capable of forming an accurate upper block by being able to form a retaining wall by masonry, and at the same time maintaining a fixed state of the clip in the block.

According to the present invention for achieving the above object, the front surface, which can be generally formed in the shape of a variety of patterns, the trapezoidal shape from the front side to the rear side has a slope angle, the rear side is connected to the side toward the rear side and the rear side having a protruding jaw And a through hole penetrating to a bottom surface in a plane corresponding to a side length, and the retaining wall block having a connection portion for connecting an upper block to a plane between the through hole and the front surface, wherein the connection portion is one plane of the through hole.
