Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block construction method for forming an outer wall or a partition wall of a building such as a house.

[0002]

2. Description of the Related Art Reinforced concrete block structures (hereinafter referred to as block structures) have been widely used as building structures mainly for houses. For example, as shown in FIG. 5, the blocks 1, ... Are stacked on a reinforced concrete cloth foundation 6, and the hollow bars 2 are filled with reinforcing bars 3 and 4 in the vertical and horizontal directions at predetermined intervals. The rebar 3,4
The cavities 2, ... containing the above are filled with concrete 5, ... for reinforcement. Incidentally, FIG. 6 shows the shape and dimensions of the three-hole block 1.

[0003]

By the way, recently, due to the diversification of lifestyles, a basement room for children's playground or storeroom, piano or karaoke performance, etc. has been established, and the third floor up to 10m above the ground. Built houses have become desired.

However, the conventional block structure described above has a relatively low strength against a horizontal load such as seismic force, and is not suitable for a high house having a basement. Moreover, the heat insulation effect and the sound insulation effect were not sufficient.

The present invention has been made in view of such circumstances.
It is an object of the present invention to provide a construction method of a block structure that is strong against horizontal load and has good workability suitable for a high house having a basement.

[0006]

The present invention comprises means for solving the above-mentioned problems as follows. That is, stacking wide blocks on a cloth foundation,
An H-shaped steel is inserted upright in the required portions of the hollow portion of the block, and vertical rebars and horizontal rebars are inserted into the other hollow portions at predetermined intervals, and cement, sand, water, and a foaming agent are added to each hollow portion. It is characterized in that a filler is mixed and mixed at an appropriate ratio.

[0007]

The H-shaped steel is inserted upright in the necessary portions of the hollow portion of the block formed to be wide, and the block is integrated with the block by the filling material, whereby the strength against horizontal load is remarkably improved.

Further, since the filling material is also placed in the other hollow portions, the heat insulating and sound insulating effects are improved. Further, since the filler is composed of cement, sand, water, and a foaming agent and has high fluidity, workability is good and the occurrence of problems such as separation after construction can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a block construction method according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a transverse cross-sectional view of a constructed block structure (outer wall), FIG. 2 is a partially longitudinal perspective view thereof, and FIGS. 3A and 3B are a plan view and a cross-sectional view of a basic block. In these drawings, reference numeral 1 is a basic block formed to be wide in order to carry out the construction method of the present invention, 11 is a deformed block for a corner, 1a and 11a are hollow portions formed in the block, and 2 is a hollow block. Block 1, 1
Between the spaces 1 and 11, and 3 are vertical rebars vertically inserted into the hollow portions 2, ... at intervals of 40 cm, and 4 are transversely spaced at intervals of 20 cm in the hollow portions 2 ,. The horizontal rebar inserted in the, 7 is the hollow portion 11 at the corner
It is an H-shaped steel that is erected upright in the cavity portions 2 at a intervals required for a and strength, and functions as a strong reinforcing steel material.

The above blocks 1, 11, ... Are stacked on a cloth foundation 6 which is rigidly formed of reinforced concrete, and the H-shaped steel 7 is used for bolts (not shown) planted in the cloth foundation 6. The lower end is fixed by screwing with a nut, while it penetrates through the girder 9 and the floor slab 10 of the intermediate layer (see FIG. 4), and the top floor (3
It is fixed to the roof slab (not shown) on the first floor by bolts or the like. Further, the vertical reinforcing bars 3 and the horizontal reinforcing bars 4 are stretched in a grid pattern in the vertical and horizontal directions. The terminal of the vertical rebar 3 is a cloth foundation 6,
It is fixed to the girder 9 and roof slab, but a joint may be provided to connect it appropriately. Further, the hook of the horizontal reinforcing bar 4 is hooked on the vertical reinforcing bar 3 to increase the fixing force, and the end portion of the horizontal reinforcing bar 4 is fixed to the H-shaped steel 7 by screwing or the like.

Then, the H-shaped steel 7, the vertical reinforcing bars 3 and the horizontal reinforcing bars 4 are inserted into the respective hollow portions 1a, 11a, 2 and the other respective hollow portions 1a, 11a, 2 and cement, sand, water and Filling material 8 called air mortar, in which a foaming agent is mixed at an appropriate ratio, is placed and each block 1, 1
1 and the H-shaped steel 7, and the vertical reinforcing bar 3 and the horizontal reinforcing bar 4 are integrated and effectively reinforced. Further, the joint mortar m is filled in the horizontal joint c and the vertical joint d between the blocks 1 and 11 to further improve the rigidity (see FIG. 2).

A suitable material for the air mortar 8 as a filler is, for example, Acecon (trade name) of Acecon Industry Co., Ltd. This is because raw mortar, which is a mixture of cement, sand, and water at a specified mixing ratio, is brought into the site by an agitator car, and a bubble generator generates sticky and highly dispersible bubbles, which are weighed in the agitator. It is put and kneaded, and it can be placed by a pump car like concrete, and it has excellent fluidity and does not cause problems such as separation after placing. By the way, Table 1 shows the blending ratio of this Acecon.

[0013]

[Table 1]

The weight of the air mortar 8 described above is about 1/2 to 1/3 of that of concrete due to the inclusion of bubbles, which is extremely lightweight and inexpensive. Moreover, it is strong against vibration and has high sound insulation, and also has extremely high heat insulation due to air bubbles and has good durability.

The above-mentioned basic block 1 is shown in FIG.
As shown in (B), the width dimension thereof is larger than that of the conventional block 1 (see FIG. 6), and the side walls 1b and 1b projecting outwardly on both sides, and a pair of lateral walls 1c orthogonal to them. , 1c has a rectangular hollow portion 1a surrounded by the center, and the height of the lateral wall 1c is about half of that of the side wall 1b. Even if a deformed block is not used, the horizontal reinforcing bar 4 is provided between the basic blocks 1 and 1. The main feature is that it can be inserted (see FIG. 2).

Further, the H-shaped steel 7 having a high reinforcing effect used in the present construction method is basically inserted into the hollow portion 11a of the deformed block 11 for the corner at each corner portion, but the middle portion. In the partition wall 12 as well, the H-shaped steel 7 is provided in the cavity portion 2 between the basic blocks 1 and 1 at intervals required for strength depending on the scale of the building.
Can be provided. As a result, the strength against a horizontal load is dramatically improved, and it is possible to reasonably build a house on the third floor above the ground having the basement 13 (see FIG. 4) with good earthquake resistance.

Since the outer wall reinforced by the H-shaped steel 7 has high rigidity as described above, during construction, after forming the surrounding wall 14 of the basement 13 (see FIG. 4), the dug up space 15 outside thereof is formed. The air mortar 8 can be cast and backfilled to solidify the surroundings of the basement 13 as the foundation of the building. The backfilling work can be easily performed in the city using a pump car, as in the case of pouring fresh concrete, and the workability is extremely good.

[0018]

As described above, according to the block construction method of the present invention, since the H-shaped steel is vertically inserted through the required portion of the hollow portion of the block and integrated with the block by the filler, The strength against load is dramatically improved, and a high three-story structure can be formed without difficulty.

Further, since a filler made of a mixture of cement, sand, water, a foaming agent and the like in an appropriate ratio is placed in the hollow portion, the filler has good fluidity, so that it is separated after placing. It is possible to form a highly durable block structure with good heat insulation and sound insulation and good workability.

Further, since the wall body can be firmly formed by using the H-section steel, when the basement is formed, it is possible to easily backfill with the filling material and form a strong foundation.
