Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a concrete wall construction method, a concrete wall device, and its concrete wall body, and is suitable for use in non-wooden construction in small-scale buildings such as residences and medium-sized office buildings. architecture, i.e.
This article relates to concrete wall construction methods, concrete wall devices, and concrete wall bodies for steel frame buildings.

(Prior art) Conventionally, in this type of relatively small-scale non-wooden construction,
A plurality of long iron mounting members are welded between the upper and lower H-beam beams, and a metal mesh is erected between the surfaces of these mounting members.
Apply mortar on top of it and build a wall, or
A concrete wall was constructed by forming a panel-shaped precast concrete wall with joint fittings embedded in its surface, and attaching the joint fittings of this concrete wall directly to H-shaped steel.

(Problems to be Solved by the Invention) However, according to this conventional wall construction method, for example, although mortar walls have the advantage of being inexpensive and can be constructed in any shape, they are durable because they are made of mortar. It had disadvantages such as poor quality, many cracks and stains, and the construction work had to be done by skilled local workers.

Additionally, construction methods that involve direct attachment of precast concrete walls have the advantage of short construction times and superior waterproofness, durability, and strength; however, the precast concrete walls themselves are It is thick and heavy, making it difficult to transport, and this also makes construction work difficult.

Therefore, the present invention was created in order to eliminate the above-mentioned drawbacks that existed in the past, and provides a concrete wall construction method and a concrete wall that are excellent in waterproofness, durability, and strength, and can be constructed easily and inexpensively. The purpose of this invention is to provide a device and its concrete wall.

(Means for Solving the Problem) For this reason, the present invention fixes an elongated wall mounting member between upper and lower beam members for mounting a concrete wall at a concrete external wall construction location. On the other hand, a concrete wall is formed that is provided with supporting reinforcing bars that continuously protrude from the wall surface at appropriate intervals at a constant height, and the wall mounting member is provided with:
By fixing this supporting reinforcing steel and adopting a concrete wall construction method that constructs a concrete wall so that there is a predetermined space between the concrete wall and the wall mounting member, The long wall-mounting member fixed between the upper and lower beams for attaching the concrete wall, and the supporting reinforcing bars fixed to this wall-mounting member are installed at appropriate intervals at a certain height. By adopting a concrete wall device consisting of a concrete wall that is formed so as to continuously protrude from the wall surface, we also have a long concrete wall that is fixed between the upper and lower beams for attaching the concrete wall. The above objective was achieved by using a concrete wall with support reinforcing bars that continuously protrude from the wall surface at appropriate intervals and at a constant height so as to be fixed to the wall mounting members.

(Function) According to the concrete wall construction method of the present invention, a long wall mounting member is installed between the upper and lower beams for attaching the concrete wall at the concrete exterior wall construction position. On the other hand, if a concrete wall is formed with supporting reinforcing bars that continuously protrude from the wall surface at appropriate intervals at a constant height, and the supporting reinforcing bars are fixed to the wall mounting member, the concrete wall and A concrete wall is constructed to have a predetermined space between it and the wall mounting member, and that space can be filled with insulation material, and interior materials can be directly attached to the back of the wall mounting member as appropriate. becomes.

In addition, in the case of concrete wall equipment, at the concrete external wall construction position, a long wall mounting member fixed between the upper and lower beams for attaching the concrete wall,
The support reinforcing bars of the concrete wall that are formed to continuously protrude from the wall surface at a certain height at appropriate intervals are fixed so that there is a predetermined space between the concrete wall and the wall mounting member. A concrete wall is constructed.

The concrete wall is then fixed at a certain height at appropriate intervals so that it can be fixed to the elongated wall mounting member fixed between the upper and lower beams for attaching the concrete wall. Support reinforcing bars are provided that continuously protrude from the wall surface, and are similarly fixed to the wall mounting member so as to fill a predetermined space, and are reinforced by the supporting reinforcing bars to reduce the thickness of the supporting reinforcing bars.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

Reference numeral 1 shown in the figure is a wall mounting member 1 for mounting a concrete wall 2, which will be described later, and is formed from an iron plate into an elongated shape having a U-shaped cross section.

The wall mounting member 1 is placed between the upper and lower beam members A, such as H-beam steel, as shown in the figure, for attaching the concrete wall 2, with the open end side of the U-shaped cross section facing outward.
They are fixed by welding multiple pieces at regular intervals.

On the other hand, the concrete wall 2, which is fixed to the wall mounting member 1 and constructed as an external wall, is formed of a precast concrete plate with a thickness of about 5 to 6 (up to), and is installed at appropriate intervals from the wall surface. Support reinforcing bars 3 are provided that continuously protrude at a constant height.

That is, as shown in the figure, the support reinforcing bars 3 include a corrugated member 3a whose side surface is bent into a substantially corrugated shape, and a bar-shaped buried chord member fixed to a protrusion of the corrugated member 3a and embedded and fixed within the concrete wall body 2. 3b, or, as shown in FIGS. 5 to 8, it is composed of a corrugated member 3a, an embedded chord member 3b, and an exposed chord member 3C fixed to the other protrusion of the corrugated member 3a. .

As shown in Fig. 3, the supporting reinforcing bars 3 are made up of several sets of two mutually inclined bars buried in the concrete wall 2 so as to form a V-shape on the planar road. Beam material A
The exposed protrusion of the corrugated material 3a is directly welded and fixed to the inner side of the wall mounting member 1 which is fixed in between, with the open end of the U-shaped cross section bent slightly outward.

Therefore, by embedding and fixing the two supporting reinforcing bars 3 in the concrete wall 2 in a substantially V-shaped plane, the strength of the concrete wall 2 itself is reinforced, and
By fixing the support reinforcing bars 3 to the wall attachment member 1, the attached state of the concrete wall 2 becomes extremely strong even against wind pressure.

Moreover, the wall mounting member 1 is made of the corrugated material 3a of the support reinforcing bar 3.
Since there are a large number of fixing points to the buried chord members 3b at regular intervals, the supporting reinforcing bars 3 are firmly fixed to the concrete wall 2 and the wall mounting member 1.

The shape and configuration of the support reinforcing bars 3 and the wall mounting member 1,
Of course, the mounting state and the like are not limited to this, and various choices can be made.

That is, as shown in FIG. 4, the open end of the wall mounting member 1, which has a U-shaped cross section, is bent into a substantially doglegged shape, and a set of support reinforcing bars inclined in a planar shape substantially in a doglegged shape are attached to the outside of the open end. The exposed protrusions of the corrugated members 3a of No. 3 are welded and fixed, respectively, or as shown in FIG. Then, the corrugated members 3a of a set of supporting reinforcing bars 3, each having a rod-shaped exposed chord member 3C fixed between the protruding parts, are welded and fixed, or as shown in FIG. An exposed chord material 3C is fixed to each exposed protrusion of the corrugated material 3a of a set of support reinforcing bars 3, and the open ends of the wall mounting member 1 are caulked from the inside to the outside so as to substantially cover the exposed chord material 3C. Processing and fixing, as shown in Figure 7,
The exposed chord members 3C are fixed to the exposed protrusions of the corrugated members 3a of a set of support reinforcing bars 3 that are inclined in a substantially V-shaped plane so as to touch each other, and a wall mounting member is attached to the outside of the protrusions of the corrugated members 3a. As shown in FIG. 8, exposed chord members 3c are attached to the exposed protrusions of the corrugated members 3a of a set of support reinforcing bars 3 that are inclined in a substantially V-shape in plan view. It is also possible to fix them close to each other and swage the open end of the wall mounting member 1 so as to cover the adjacent exposed chord members 3c from the inside to the outside.

In this way, the concrete wall 2 is constructed by fixing the supporting reinforcing bars 3 provided on the concrete wall 2 to the wall attachment members 1 fixed between the upper and lower beams A.

Note that the reference numeral 4 shown in FIG. 2 is a heat insulating material such as rock wool that is filled in the required space between the wall mounting member 1 formed by the supporting reinforcing bars 3 and the concrete wall 2; is a covering material made of gypsum board, plywood, etc. attached to the wall mounting member 1.

Next, a concrete wall construction method according to the present invention will be explained.

First, at the construction location of the concrete external wall of the building, between the upper and lower beams A for attaching the concrete wall 2,
A plurality of elongated wall mounting members 1 having a U-shaped planar cross section are welded and fixed at regular intervals with the open end side facing outward. On the other hand, a precast concrete wall body 2 is formed which is provided with supporting reinforcing bars 3 that continuously protrude from the wall surface at appropriate intervals at a constant height. Then, by fixing the supporting reinforcing bars 3 to the wall mounting member 1 fixed between the beams A by welding or the like, a predetermined space is created between the concrete wall 2 and the wall mounting member 1. Build concrete wall 2.

Next, this space is filled with a predetermined heat insulating material 4, and then the interior material 5 is attached to the back surface of the wall mounting member 1 with appropriate needles or the like.

(Effect of the invention) Therefore, the present invention provides the following advantages:
A long wall mounting member 1 is fixed between the upper and lower beams for mounting the concrete wall 2, and supporting reinforcing bars 3 are provided that continuously protrude from the wall surface at a constant height at appropriate intervals. By forming a concrete wall 2 and fixing the support reinforcing bars 3 to the wall mounting member 1, the concrete wall 2 is formed such that a predetermined space is provided between the concrete wall 2 and the wall mounting member 1. By constructing a wall, the concrete wall 2 can be firmly attached by simply fixing the supporting reinforcing bars 3, which continuously protrude from the wall at appropriate intervals and at a constant height, to the wall mounting member 1. I can do that.

Furthermore, since the concrete wall body 2 is installed with a predetermined space provided by the supporting reinforcing bars 3, the space can be filled with the heat insulating material 4, and a concrete wall with excellent heat insulation properties can be constructed.

Then, the interior material 5 is placed on the back of the wall mounting member 1 as appropriate.
can be installed directly, which greatly simplifies indoor interior work.

For this reason, the concrete wall device consists of a long wall mounting member 1 fixed between upper and lower beams A for mounting the concrete wall 2, and the wall The supporting reinforcing bars 3 fixed to the mounting member 1 are
Since the concrete wall body 2 is formed to continuously protrude from the wall surface at a certain height at appropriate intervals, as mentioned above, a heat insulating material 4 is filled in a predetermined space formed by the support reinforcing bars 3 to improve heat insulation. In addition to being able to build excellent concrete walls,
The supporting reinforcing bars 3 of the concrete wall 2 are fixed to the wall mounting member 1, so that the concrete wall can be built strongly.Moreover, since the concrete wall 2 itself is reinforced by the supporting reinforcing bars 3, the thickness of the concrete wall 2 is 5. It can be formed as thin as ~8 cm. Therefore, compared to the conventional precast concrete wall with embedded joint fittings that are directly attached to beam material A, transportation and handling are extremely easy, and concrete wall construction work such as hanging and erection is easier. Moreover, it becomes a concrete wall device with excellent waterproofness, durability, and strength.

And that concrete wall is concrete wall 2
In order to be fixed to the elongated wall mounting member 1 fixed between the upper and lower beam members A for mounting, support reinforcing bars 3 are provided that continuously protrude from the wall surface at a constant height at appropriate intervals. Therefore, since it is reinforced by the supporting reinforcing bars 3, its thickness can be reduced, making it easy to handle and having excellent workability.Moreover, as mentioned above, the supporting reinforcing bars 3 make it possible to have a predetermined space. Since it can be fixed to the wall mounting member 1 at the same time, the space can be filled with the heat insulating material 4 and a concrete wall with excellent heat insulation properties can be constructed extremely easily.
