The present invention relates to a wooden exterior retaining wall block in which wood is disposed on the front surface.

As a conventional retaining wall block, for example, one disclosed in Japanese Patent Application Laid-Open No. 2002-2225 filed by the applicant of the present invention is proposed. This retaining wall block is molded from precast concrete to build the retaining wall.

As such, the retaining wall of the concrete block is not environmentally friendly, and there is little intimacy, so there are many cases in which artificial wooden concrete blocks are molded to look natural as wood.

However, artificial wood blocks are also non-environmental because they are made of concrete, and are significantly less friendly than natural wood.

In addition, although the weight of the concrete block is different depending on the size, it is usually too heavy for the operator to lift the machine to the working position is required.

Therefore, it is preferable that the whole retaining wall block is made of wood as a natural and light weight. However, in the case of using the wood block, the cost is very expensive, there is a limit that the crack of the wood may occur due to the pressure between the blocks, and above all, the volume is inevitably very large to withstand the earth pressure.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a wooden exterior retaining wall block which can reduce weight while being friendly and environmentally friendly.

Retaining wall block of the present invention for achieving the above object comprises a body made of concrete, and a wooden exterior member disposed on the front of the body.

According to this structure, the weight can be reduced while being friendly and environmentally friendly by the wood exterior member.

In the above-described configuration, a channel-shaped opening is formed on the front surface of the body, grooves formed with stoppers are formed on both sides of the opening, and the wood exterior member is provided on an exterior portion disposed on the front surface of the body, It is preferably composed of a protrusion disposed and a coupling protrusion installed in the protrusion and coupled to the groove.

In addition, a coupling groove is formed on the upper surface of the wood exterior member and the upper surface of the body, and the coupling groove is preferably coupled to the coupling groove.

In addition, the wood exterior member may be coupled to the body by an adhesive.

On the other hand, if the upper surface and the lower surface of the wood exterior member is inclined downward from the rear toward the front surface, the pressure does not work through the non-contact between the wood exterior member can be eliminated defects such as cracks.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Example 1

Figure 1a is a perspective view showing a separated wooden retaining wall block according to a first embodiment of the present invention, Figure 1b is a coupling plan view of Figure 1a, Figure 1c is a cross-sectional view taken along the line A-A of Figure 1b.

As shown in Figure 1a to 1c, the wooden exterior retaining wall block 100 according to the first embodiment of the present invention is installed on the body 110 of the concrete material, and the front surface 111 of the body 110 is installed Consists of a wood exterior member 150.

The body 110 has a front surface 111 and a rear surface 113, an upper surface 115, a lower surface 117, and a side surface 119 facing forward. In addition, the body 110 is formed with a plurality of pin receiving portion 121 formed downward from the upper surface 115 along the stacking direction, the pin receiving portion 121 is inserted into the pin receiving portion 121. Each pin receiving portion 121 has a predetermined interval in the left and right directions. The lower surface 117 of the body 110 is formed with a pin head receiving portion 123 recessed from the lower surface 117 to correspond to the pin receiving portion 121 of the stacked surface of another adjacent block. The pin head accommodation portion 123 is biased forward with respect to the axis of the pin accommodation portion 121. In addition, the pin head accommodation portion 123 communicates with the pin accommodation portion 121. In addition, the body 110 has a penetrating opening 125 formed in the body 110 near the rear surface 113 in more detail. The opening 125 serves to reduce the weight of the body 110 and may be filled with mortar or aggregate and / or soil in a stacked state (for more detailed description, refer to Korean Patent Publication No. 2002-2225). ).

In addition, a channel-shaped opening 130 is formed in the front surface 111 of the body 110, and guide grooves 131 formed in the vertical length direction are formed on both side surfaces of the opening 130. The guide groove 131 is formed with a stopper 133 for stopping the projection 155 described later.

The wood exterior member 150 is composed of an exterior portion 151 forming a front surface of the block and a protrusion 153 accommodated in the opening 130.

Exterior portion 151 is preferably made of a size to cover the front surface 111.

Protrusions 155 are provided on both sides of the protruding portion 153. The protrusion 155 is fitted into the guide groove 131 and is assembled to the body 110 while being mounted on the stopper 133.

Since the wood exterior member 150 is assembled to the body 110, first, the wood exterior member 150, which is a natural wood, is disposed on the front surface 111 of the body 110, thereby realizing an environmentally friendly retaining wall. Second, the distance between the front surface 111 of the body 110 and the pin receiving portion 121 is reduced (that is, the distance is reduced by the thickness of the exterior portion), the weight is reduced by the space of the opening 130, so that the total weight of the assembly block Significantly reduced, can improve worker workability.

On the other hand, when the building blocks are stacked and stacked, if the upper and lower surfaces of the exterior part 151 are in surface contact with each other, defects such as cracks may occur in the wood due to the pressing pressure. In order to solve such a defect, when the upper and lower surfaces are spaced apart from the retaining wall, the concrete body 110 may be seen and the natural friendliness may be degraded. In order to solve this problem, as shown in FIG. 1C, it is preferable to implement the inclined surfaces 156 and 157 which are inclined downward on the upper and lower surfaces of the exterior part 151. That is, the inclined surfaces 156 and 157 are inclined to become thinner from the rear surface 154 of the exterior portion 151 toward the front surface 152.

Example 2

Figure 2 is a perspective view showing a wooden exterior retaining wall block according to a second embodiment of the present invention. Retaining wall block 200 of the second embodiment is composed of a concrete body 210 and a wooden exterior member 250 as in the first embodiment.

By the way, the assembly of the body 210 and the wood cladding member 250 is different from the assembly of the first embodiment that is performed by the connecting piece 230. That is, the connecting piece 230 is a channel-shaped member composed of vertical pieces 231 on both sides and a horizontal piece 233 connecting the vertical pieces 231. A coupling groove 255 into which the connection piece 230 is inserted is formed on the upper surface of the body 210 and the wood exterior member 250. The coupling groove 255 is composed of a vertical coupling groove 251 to which the vertical piece 231 is coupled and a receiving coupling groove 253 to which the horizontal piece 233 is coupled. Since the receiving coupling groove 253 arranges the connecting pieces 230 in a recessed state, when the blocks are stacked on each other, the connecting pieces 230 are not hindered, which is preferable.
