Description

  The present invention relates to a construction method of a building, and more particularly, to a construction method of a building having a structural body constructed using a concrete block.

  As a building having a structural skeleton built using concrete blocks, a building using reinforced concrete masonry (RM) (see the Ministry of Land, Infrastructure, Transport and Tourism Notification Nos. 461 to 463) and the like have been proposed and put into practical use. ing.

By the way, reinforced concrete masonry (RM) has a so-called skeleton-infill structure, that is, a skeleton (a structural body such as a column, a beam, a floor, etc.) of a building and an infill (interior and equipment in a dwelling unit) are separated. With such a structure, the following advantages of the skeleton-infill structure are provided.
-The skeleton (structure) has high fire resistance, earthquake resistance, wind damage, and water damage.
・ The livability of the building is excellent, and the airtightness, heat insulation, and sound insulation are high.
・ High durability in buildings, and the value does not decrease.
・ The space in the building is well-formed and pillars and beams do not protrude into the room.
・ Various floor plans are possible.
・ Easy renovation in the future.
・ Easy maintenance of equipment piping.

  On the other hand, this reinforced concrete masonry (RM) is a method of masonrying concrete blocks while arranging reinforcing bars, so it is necessary to maintain high accuracy of masonry of concrete blocks. In addition to the above, there is a problem that the operation is troublesome.

  The present invention has been made in view of the above-mentioned problems of the reinforced concrete masonry (RM), and can easily maintain the masonry accuracy of the concrete block, and can make the constructed building a skeleton-infill structure. It is an object of the present invention to provide a construction method of a building capable of performing the following.

In order to achieve the above object, a construction method of a building according to the present invention includes the following steps (1) to (4) in a construction method of a building having a structural skeleton built using a concrete block. It is characterized by the following.
(1) Basic construction process.
(2) A wooden frame construction step of installing a wooden frame composed of wooden pillars and beams inside the constructed foundation.
(3) A reinforced concrete masonry construction process of constructing a reinforced concrete masonry using a concrete block on a foundation along a wooden frame constructed inside the foundation.
(4) A slab construction process for constructing a slab by placing concrete.

  In this case, the construction step of the reinforced concrete masonry may be such that the concrete blocks are masonry while laying the horizontal streaks, and the vertical streaks are arranged after the masonry of the concrete blocks.

  Further, the wooden frame can be used as an interior of a building.

  According to the building construction method of the present invention, the accuracy of masonry of concrete blocks can be easily maintained, and the constructed building has a skeleton-infill structure, so that the skeleton-infill structure has Various advantages can be provided.

It is explanatory drawing which shows one Example of the construction process of the construction method of the building of this invention.

  An embodiment of a building construction method according to the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the construction process of the building construction method of the present invention.
The construction method of a building according to the present invention relates to a method of constructing a building having a structural frame constructed using concrete blocks, and includes the following steps (1) to (4).
(1) Foundation construction process (2) Wooden frame construction process (3) Reinforced concrete masonry construction process (4) Slab construction process

  Hereinafter, each step will be described.

(1) Foundation construction process (Fig. 1 (a))
The foundation 1 is constructed on the ground.
As the foundation 1, a foundation structure used as a foundation of a building, such as a cloth foundation or a solid foundation, can be appropriately selected according to a building to be constructed.
From the base 1, a rising streak 2 having a predetermined length is raised.

(2) Wooden frame construction process (FIGS. 1B to 1E)
Inking (ground ink 3) is performed on the inside of the constructed foundation 1 (FIG. 1B), and a wooden frame 4 composed of wooden pillars 41 and beams 42 is installed (FIG. 1C). .
An entrance frame 43 and a window frame 44 are attached to the wooden frame 4 (FIG. 1D), and a panel 45 serving as a slab form is attached at an appropriate stage (FIG. 1E).

(3) Construction process of reinforced concrete masonry (Fig. 1 (f)-(h))
A reinforced concrete masonry 5 is constructed using a concrete block on the foundation 1 (at a position where the rising bars 2 are raised) along the wooden frame 4 constructed inside the foundation 1.
For the concrete block, for example, a concrete block having a thickness of 150 mm, 200 mm, 240 mm or more (for example, a concrete block “DENX (Denx) (trade name) manufactured by Taiyo Eco Blocks Co., Ltd.) corresponding to the structural calculation of the load-bearing wall of the building ]) Can be used.
In constructing the reinforced concrete masonry 5, the concrete blocks are masonry while arranging the horizontal streaks (not shown) (FIG. 1 (f)), and after the concrete blocks are laid, the vertical streaks 6 are dropped from above. It is arranged (FIG. 1 (g)). Thereby, workability can be improved.
In addition, the construction of the reinforced concrete masonry 5 can be carried out from the inside of the building, the temporary scaffold on the outside can be omitted or simplified, and if necessary, the “zero-lot construction (site Construction without any restrictions from the boundary) is also possible.
Thereafter, grouting material made of mortar, concrete, or the like is filled into the cavity of the concrete block in which the vertical streaks 6 are arranged, thereby constructing a load-bearing wall of the building (FIG. 1 (h)).
In this way, by constructing the reinforced concrete masonry along the wooden frame 4, that is, with reference to the wooden frame 4, it is possible to easily maintain the masonry accuracy of the concrete block.

(4) Slab construction process (FIGS. 1 (i) to (k))
A slab reinforcing bar 71 is laid on a panel 45 serving as a slab form attached to the wooden frame 4 (FIG. 1 (i)).
In this state, the parapet masonry 8 is constructed on the reinforced concrete masonry 5 (at the position where the vertical bar 6 is raised) using the concrete block (FIG. 1 (j)).
Then, the slab 7 is constructed by casting concrete on the panel 45 which becomes the slab formwork on which the slab reinforcing bars 71 are laid (FIG. 1 (k)).

  Here, the embodiment shown in FIG. 1 describes a one-story building as an example, but a multi-story building (up to five stories is possible (see the notification of Ministry of Land, Infrastructure, Transport and Tourism No. 463)). In the case of (1), the step of constructing the parapet masonry 8 is omitted to construct the slab 7, and the steps (2) to (4) are repeated.

  The wooden frame 4 can be removed in accordance with the construction of the building, but a panel or a board (not shown) can be attached to the wooden frame 4 and used as the interior of the building.

  According to the construction method of this building, it is possible to easily maintain the accuracy of masonry of concrete blocks, and by making the constructed building a skeleton-infill structure, various types of the skeleton-infill structure have Advantages can be provided.

  As described above, the construction method of the building of the present invention has been described based on the embodiment, but the present invention is not limited to the configuration described in the above embodiment, and the configuration may be appropriately changed without departing from the gist thereof. Can be changed.

  The construction method of a building according to the present invention has characteristics that the accuracy of masonry of concrete blocks can be easily maintained and that the constructed building can have a skeleton-infill structure. Therefore, it can be widely used for construction of a building having a structural body constructed using a concrete block.
