BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables quick and reliable construction without using a bonding agent such as mortar for joining blocks, and devises a method of stacking blocks and a combination of types of blocks. Thus, the present invention relates to a method for constructing a pot wall and a block for a pot wall, which is finished in a kind of dignified appearance.

[0002]

2. Description of the Related Art As a method of stacking block materials to construct a wall, a method of constructing a block wall using a concrete block provided with a cavity extending vertically is well known.
Recently, as a concrete block for building a wall, a concrete block in which engaging projections and engaging grooves for stacking positioning of vertically adjacent blocks are provided on the upper surface and the lower surface of the block has been devised. In this block, the engaging projections and engaging grooves of the upper and lower blocks are engaged with each other during stacking to prevent them from slipping off securely, so the work of applying mortar for joining between blocks can be saved and reinforcing bars are almost unnecessary. become.

[0003]

In the block fence construction method described above, mortar for joining is applied between adjacent blocks in any of left, right, up and down directions, and further, mortar is arranged while arranging reinforcing bars in the cavity. Need to be filled. Therefore, the construction requires a lot of experience and much labor and time. On the other hand, the pot wall block provided with the engaging projections and grooves does not require mortar filling or bar arrangement work, so that even unskilled persons can easily and surely perform the construction. However, since the urn wall constructed by this method is finished in a dull appearance with a knocked out surface, for example, in places where the appearance is good or bad, such as the earth retaining wall around the premises of a house, it is quite important. , Further improvement was required. Therefore, the object of the present invention is to eliminate the need for a bonding agent such as mortar, and even an unskilled person can easily, surely, and quickly perform the construction, and, depending on the ingenuity of the construction person, it is possible to build up a unique and attractive appearance. A method of constructing a wall and a block for a wall are provided.

[0004]

In order to achieve the above object, a method of constructing a pot wall and a pot wall block according to the present invention include a plurality of engagement grooves 2a and 2b on an upper surface 1a and a lower surface b, respectively. Using blocks 1 arranged in parallel in the front-rear direction at predetermined intervals, when stacking the blocks 1, vertically and horizontally adjacent blocks 1 are appropriately shifted in the front-rear direction and stacked. Adjacent to block 1,
Out of a plurality of engagement grooves on one contact surface, one or a pair of engagement grooves 2a and 2b are opposed to each other, and the engagement member 3 is inserted so as to straddle both the grooves. Therefore, a method is adopted in which the positioning and engagement of each block are performed. The engaging grooves 2a, 2b are preferably formed in a substantially L-shaped cross section, and the engaging member 3 is preferably formed in a substantially U-shaped cross section. Further, the mortar filling hole 4 may be vertically provided in a penetrating manner on one side in the longitudinal direction of the block 1.

[0005]

[Operation] To build a wall using the block 1 of the present invention,
First, the first-stage blocks 1 are set up in a column on a concrete foundation. On top of that, the blocks 1 of the second stage are set up in a column, but at that time, the blocks 1 of the first stage are simply placed.
Rather than being exactly overlapped on top of each other, the individual blocks 1 are placed in a state in which they are relatively shifted in the front-rear direction (and left-right direction) (see FIG. 1). The amount of shift can be arbitrarily determined according to the aesthetic sense of each installer. Then, in parallel with this stacking work, the adjacent blocks 1,
The work of engaging the ones with each other by the engagement member 3 and performing the stacking positioning is performed. This work is extremely simple. First, among the plurality of engagement grooves 2a provided on the upper surface of each block 1 in the lower stage, the position where the engagement effect with the block 1 in the upper stage is considered to be the largest is located. The lower half portion of the engaging member 3 is dropped into one engaging groove 2a. At that time,
The engagement member 3 is provided so as to straddle between the blocks 1 and 1 that are adjacent to each other on the left and right. After that, the block 1 of the second stage is attached to the engagement member 3 in which a predetermined one of the plurality of engagement grooves 2b provided on the lower surface of the block 1 is half projected to the upper surface of the block 1 of the first stage. Place it so that it fits in. As a result, the blocks 1 adjacent to each other in the vertical and horizontal directions are engaged with the engaging members 3
Are firmly engaged with each other and positioned.
If the blocks 1 of the third stage and above are stacked in the same manner as above, the construction work of the wall is extremely easy and quick,
And surely complete. The front surface of the completed pot wall can be finished with an uneven surface with a kind of dignified aesthetic, depending on the sense of the builder, unlike the flat surface of the conventional construction method.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a retaining wall for earth retaining will be described below with reference to the drawings. The block 1 of this embodiment shown in FIG. 2 is made of concrete, and is formed into a substantially rectangular parallelepiped in which the dimension ratio of length, width and height is arbitrarily selected. Although not shown, the front side of the block 1 may be subjected to various well-known decorative processes such as a “split surface”.

A flat upper surface 1a and a lower surface 1b of the block 1
As shown in the figure, the engaging grooves 2a and 2b are provided in the front-back direction of the block 1 at a predetermined interval and have substantially vertical symmetrical shapes.
Are provided in parallel in the left-right direction of the block 1, each having a plurality of rows. In this case, the number of grooves is four on each of the upper and lower surfaces, and the groove intervals are the same. Also, the engaging grooves 2a, 2b
As for the cross-sectional shape, the engagement groove 2a on the upper surface side is formed into a substantially L shape, and the engagement groove 2b on the lower surface side is formed into a substantially L shape which is upside down.
Further, the shapes and dimensions of the block 1 are not made uniform, and a plurality of types are prepared just like building blocks of a toy (see FIG. 1).

FIG. 3 shows an engaging member 3 for positioning the blocks 1 vertically and horizontally adjacent to each other and engaging them integrally. The engaging member 3 of this embodiment has a shape similar to a section steel having a U-shaped cross section, and its length dimension is equal to or a few times that of the block 1. The metal engaging member 3 is rustproofed. As shown in FIG. 1, the dimension of each part of the cross-section of the engaging member 3 is the same as that of the engaging grooves 2a, 2b provided in the contact surfaces of the vertically adjacent blocks 1, 1 respectively. , Each one 1
With the pair of engaging grooves 2a, 2b brought to the facing position,
The engaging member 3 is set to have a size such that it can be tightly and easily fitted by straddling the grooves 2a and 2b.

In FIG. 1 showing the construction of the pot wall A, the block 1A for the uppermost stage of the pot wall A may, of course, be provided with the engaging groove 2b only on the lower surface 1b side. Symbols B and C in FIG. 1 are the ground, D is a concrete foundation for building the wall A, E is a reinforcing bar for the foundation, and F is a mortar for joining.

FIG. 4 shows a lower block 1B. Semi-cylindrical depressions 1c are provided vertically on the left and right side end surfaces of the block 1B. Mortar is injected into the recess 1c in a state in which the reinforcing bar E projected on the concrete foundation D is inserted as shown in FIG.

Next, the operation of the above configuration will be described with reference to FIG. To build the pot wall A using the block 1 (and 1A, 1B) and the attached engaging member 3, first, the concrete foundation D is placed. At that time, the first block 1
An L-shaped rebar E for firmly combining B with the concrete foundation D is arranged as shown.

On the concrete foundation D, the blocks 1B of the first stage are set up in a column form while laying mortar. At this time, the blocks 1 and 1 that are adjacent to each other on the left and right may be slightly shifted in the front-rear direction so as to have a change in design. Also, mortar is injected into the recess 1c where the reinforcing bars E are arranged.

Next, the second-stage blocks 1 are set up in a column, but mortar is not used at that time. Then, rather than simply placing them on the first-stage block 1 in an accurate manner, the individual blocks 1 are formed so that a rough surface with a decorative effect is formed on the front surface of the completed pot wall A. Should be relatively shifted in the front-back direction (see FIGS. 1 and 6). The amount of shift can be freely determined according to the aesthetic sense of the individual builder.

In parallel with the stacking work of the second stage block or prior to the stacking work, the mutual engagement of the blocks 1B of the first stage and the blocks 1B and 1 of the first stage and the second stage
Assembling work of the engaging member 3 which plays a role of engaging and with each other is performed. This operation is extremely simple. First, of the plurality of engaging grooves 2a on the upper surface 1a of each block 1B of the first stage, the degree of deviation in the front-rear direction between the blocks 1B, 1 of the first and second stages is large. Therefore, one engagement groove 2a that occupies the position where the engagement effect is maximized is selected, and the lower half portion of the engagement member 3 is dropped. At this time, the length of the engaging member 3 is the block 1B.
If the length is shorter than the length, the engaging member 3 is dropped while straddling between the blocks 1B, 1B adjacent to each other on the left and right.

After that, the block 1 of the second stage is placed. At that time, a predetermined one of the plurality of engaging grooves 2b on the lower surface 1b of the block 1 is inserted into the upper half of the engaging member 3 protruding above the block 1B of the first stage. To be Then, pushing the second block 1 forward,
The engaging member 3 straddles both engaging grooves 2a and 2b and is fixed in the groove without rattling. After that, if the blocks 1 of the third stage and above are sequentially stacked in the same manner as described above, the construction work of the wall A can be completed extremely easily, quickly and surely.

Since the front surface of the completed pot wall A is not a simple "one-sided surface" but an uneven surface that has been devised in terms of design, a kind of dignified appearance that is not required for conventional pot walls Is finished.

5 and 6 show a block 1C for corners for constructing the corners of the wall A and a method for constructing them. In this block 1C, a mortar filling hole 4 is vertically provided in a penetrating shape on one side portion in the longitudinal direction.
Further, the front edge and one side surface of the block 1C are chamfered in order to decorate their upper edges.

FIG. 6 shows an example of the structure of the corner portion of the wall which is constructed by using the block 1C. The vertically adjacent blocks 1C, 1C are stacked orthogonally to each other as shown in the drawing, and the mortar filling holes 4 are vertically communicated with each other. The mortar is filled in each of the communicating mortar filling holes 4 with the reinforcing bars E disposed therein. This ensures the structural strength of the corner of the wall.

In the above structure, the object of the present invention can be achieved even if the detailed structure is appropriately changed in design. For example,
The cross-sectional shape of the engagement grooves 2a and 2b is not limited to the illustrated shape, and may be trapezoidal or any other shape. In that case, the cross-sectional shape of the engaging member 3 may be made to correspond to the shape of the engaging grooves 2a and 2b. The arrangement and number of the engaging grooves 2 may be determined according to the size of the block 1.

[0020]

As is apparent from the above description, when the method for constructing a pot wall and the block for a pot wall according to the present invention are adopted, various excellent effects as listed below can be obtained. (A) Since no mortar is used to connect the walls of the wall to each other, even an unskilled person can perform the construction very easily, reliably, and quickly. (B) The blocks adjacent to each other vertically and horizontally are integrated with each other by the engaging force of the engaging members with an engaging strength comparable to that of the conventional adhesive mortar. (C) Therefore, even if it is not purposely reinforced with reinforcing bars, there is almost no possibility that the wall will collapse due to strong lateral pressure or rocking of the wall when a heavy rain or an earthquake occurs. (D) The blocks that make up the pot wall are stacked in a state that they are offset from each other in the front-rear direction, so that the front face of the pot wall is not a uniform flat surface with no knockers, but an excellent change in decorativeness. It can be formed on a rich uneven surface.
