Description

TECHNICAL FIELD The present invention relates to a wall construction method that can reduce the construction cost and the construction period.

[Prior Art] In the conventional construction method for walls such as basements, as shown in Fig. 16, the outer wall 1 is constructed with a veneer formwork, etc., which are tightly connected with a separator etc. to perform formwork work. After constructing the outer wall 1 by pouring concrete into the outer wall 1, a concrete block 2 as a double wall is stacked using mortar inside the outer wall 1 with a gap 1a. Then, the infiltrated water from the outer wall is guided to the drainage tank 4 through the drainage pipe 3 for drainage treatment.

[Problems to be Solved by the Invention]

However, the conventional wall construction method has the following problems to be solved in formwork work and block work.

First of all, as a problem in formwork construction, a hole is formed for a streak for concrete block construction, or a stud for a concrete block is formed, so that the formwork becomes complicated and the number of steps is generally increased. The work space is not available, so laborsaving construction methods such as large formwork cannot be adopted.

Also, as a problem in concrete block construction,
A space 1a is required between the outer wall 1 and the concrete block for stacking, horizontal movement is required when the concrete block is loaded, and further, because the blocks are stacked with mortar, the construction speed is slow and the mortar It may need cleaning.

The present invention solves the above problems, and an object of the present invention is to provide a wall construction method that can increase the effective space of a room and can reduce the construction cost and the construction period.

[Means for Solving the Problems]

Therefore, the present invention is a method of constructing a wall constructed by placing concrete in the molds arranged on the outside and the inside, and the molds arranged on the inside consist of stacking concrete blocks 2. Concrete block 2
Has both side walls 2a having step portions 2h formed at both end portions and partition walls 2b formed between the side wall portions 2a, and when the concrete blocks 2 are stacked, the joint portion of the concrete block 2 is formed by the step portions 2h. The feature is that it has 10 gaps. Incidentally, the convex portion may be formed on the upper portion of the partition wall and the concave portion may be formed on the lower portion of the partition wall,
In addition, convex portions are provided at both ends of the concrete block 2 in the longitudinal direction.
2e and the concave portion 2f may be formed, or the convex portions 2c and 2e and the concave portions 2d and 2f may be formed at both ends in the vertical direction and the longitudinal direction.
Alternatively, the concrete block 2 bent at a right angle may be used and arranged at the corner portion.

It should be noted that the numbers added to the above-mentioned configurations are for comparison with the drawings, and the configurations are not limited thereby.

[Action]

In the present invention, for example, as shown in the figure, the concrete block 2 is fitted with the respective convex portions 2c and 2e and the concave portions 2d and 2f, stacked and bent, and is welded to the mountain retaining parent pile 12 by a separator.
The other end of 15 is fixed with a bolt 19 through a vertical end thickness 16 and a horizontal end thickness 17. When concrete 5 is placed in a formwork made up of a concrete block and another formwork, concrete 5
The concrete block 2 and the concrete 5 are integrated into the joint 10 of the concrete block 2 and the outer wall 1 is formed.
Is built. Groundwater entering from the outer wall enters from the joint portion 10 of the concrete block 2 and falls between the partition walls 2b,
From the drainage block 7 through the drainage pipe 3 to the drainage tank 4 for drainage treatment.

In contrast to the above-described embodiment, in which the convex portion 2c and the concave portion 2d are provided in the vertical direction of the partition wall 2b of the concrete block 2, in the present embodiment, both side walls 2a having step portions 2h at both ends and between the both side walls 2a are provided. This is different in that it has a partition wall 2b formed in the above, and a convex portion 2e and a concave portion 2f are respectively formed in the partition walls 2b at both ends. First
FIG. 12 shows a state in which the convex portion 2e of a certain concrete block 2 is fitted into the concave portion 2f of another concrete block 2 and arranged horizontally.

8 to 10 show still another embodiment of the concrete block used in the present invention, and FIG. 8 is a front view,

This embodiment is different from the other embodiments described above in that the partition wall 2b is provided with the projections 2c and the recesses 2d in the vertical direction, and the partition walls 2b at both ends are also provided with the projections 2e and the recesses 2f, respectively. .

FIG. 13 shows a drainage block 7 which is installed at the bottom of the concrete block 2 in each of the above-mentioned examples and has a drainage groove communicating in the horizontal direction. The drainage block 7 has the same thickness as the concrete block 2 and is made of FRP (glass fiber reinforced). Made of resin).

14 and 15 show a concrete block 21 arranged at a corner portion of a room, FIG. 14 is a plan view, and FIG. 15 is a side view. Similar to the concrete block 2, the partition walls 2b at both ends are provided with a convex portion 2e and a concave portion 2f, respectively. Also in this case, the convex portion 2c and the concave portion 2d may be provided in the vertical direction of the partition wall 2b.

Next, the construction method of the wall construction method of the present invention will be described.

In FIG. 1, formwork is performed before placing concrete 5. The earth retaining surface 11 has already been constructed, and the earth retaining parent pile 12 constructed of H-shaped steel or the like is provided. First, place the concrete block 2 at a predetermined position on the pile retaining parent pile 12.
The separator 15 is welded in advance according to the height of the joint portion 10. Subsequently, the drainage block 7 is arranged at a predetermined position, and the cochleate block 2 is attached to the respective convex portions 2c.
And the recesses 2d are fitted and stacked. Further, the convex portion 2e of the concrete block 2 is fitted in the concave portion 2f of the other cochleat block 2 and arranged horizontally. The concrete block 21 shown in FIGS. 14 and 15 is arranged at the corner of the room. After the concrete blocks 2 are piled up to the lower end of the floor slab 18, the other end of the separator 15 which has already been installed is fixed with bolts 19 through the vertical end thickness 16 and the horizontal end thickness 17. As shown in the figure, at the position where the beam formwork 13 is located,
The half block 20 is used as the concrete block 2.

When the concrete 5 is placed in the formwork thus formed, the concrete 5 enters the joint portion 10 of the concrete block 2, and the concrete block 2 and the concrete 5 are integrated to construct the outer wall 1. Groundwater and the like entering from the outer wall enters from the joints of the concrete block 2 and falls between the partition walls 2b, and the drainage block 7
Is led to the drainage tank 4 through the drainage pipe 3 for drainage treatment.

〔The invention's effect〕

As described above, according to the present invention, the space between the outer wall and the block becomes unnecessary unlike the conventional case, and the effective space of the room increases accordingly.

Further, since the work of formwork on the inner wall and the work of mortar on the cocrete block are unnecessary, the construction cost can be reduced and the construction period can be shortened.

Furthermore, since the convex portion and the concave portion are provided in at least a part of the vertical and horizontal directions of the concrete block, the construction becomes easy.
