2. Description of the Related Art In a conventional reinforced concrete building, a formwork is temporarily assembled before and after assembling a reinforcing bar, for example, at a portion for constructing a boundary wall between adjacent houses.
Concrete was cast inside the formwork to form a bearing wall.

Further, as a box-type unit forming a part of a house or the like, there is a box-type unit in which a concrete panel is assembled in a box-type, and the concrete panel itself has structural strength.

[0004]

However, in the above-mentioned conventional temporary assembling formwork, when assembling the formwork, a formwork panel, a separator, an assembling hardware, a fastening hardware and the like are used, and a column, a connecting member and the like are used. It was assembled using supports such as bracing, bracing, and erection beams. Since various types of members are combined in this way, when constructing a large building, a large amount of various types of form materials are required, and it takes a lot of time to store, temporarily assemble, adjust the dimensions, dismantle, etc. However, there is a problem that the cost is increased. When the formwork panels are continuous, unevenness and misalignment are likely to occur, and when finishing directly on the concrete casting surface, it is necessary to increase the precision of the panel to solve this, and many reinforcing materials and There was a problem that time was required.

In the conventional construction method using a formwork panel, a formwork is installed on one side and reinforced with braces, lashes, supports or the like, and then a reinforcing bar is assembled on the spot. A separator is also provided during this time. Then, after the other formwork is installed and reinforced with braces, pegs, supports, etc., concrete is poured in, and after a predetermined curing period, this formwork is dismantled. As described above, it takes time until the concrete is poured, and no internal works can be performed until the form is dismantled. Also, formwork panels need to be cleaned and reworked after use, and must be discarded after several uses. For this reason, there was a problem that the construction period was long and the construction cost was high.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem. It is an object of the present invention to construct a concrete form in a short time and easily, and to use members. It is an object of the present invention to provide a method for constructing a concrete building, which is small in size, easily obtains dimensional accuracy, and is capable of simplifying, simplifying, shortening the construction period, and reducing the construction cost of a work process.

[0007]

According to a first aspect of the present invention, there is provided a method for constructing a concrete building, wherein a plurality of box-type units are arranged at predetermined intervals and concrete is disposed within the interval. Is a method of constructing a building by connecting a frame for joints to form a box-shaped frame, and attaching a plate-shaped member to the inner and outer surfaces of the frame to form inner and outer walls. A rectangular shape formed on the outer surface of a plate-shaped member constituting at least one outer wall surface and temporarily fixing other plate-shaped members arranged to face the plate-shaped member at the time of concrete casting. A box-type unit is formed by projecting vertical guide rails that slidably fit flange portions formed on both sides of a rectangular intermediate frame made of an iron plate or a reinforcing bar and an iron plate. The knits are arranged in a state where the vertical guide rails are separated from each other by a predetermined distance and opposed to each other, and the space between the box-type units has a width and a predetermined height between the box-type units, and extends over multiple layers. A horizontal reinforcing bar is inserted into the opening of the intermediate frame, which has a plurality of openings serving as a concrete filling port, and a horizontal reinforcing bar is inserted into the opening, and a vertical reinforcing bar is disposed so as to intersect the horizontal reinforcing bar. After the prefabricated rebars formed by welding the intersections of the intersecting portions, the flanges of the intermediate frame are inserted into the vertical guide rails from the upper ends thereof and arranged between the box-type units.
The space between the box-type units is formed on the load-bearing wall by casting concrete. Also, in this case, a floor slab can be formed on the ceiling surface by using the outer surface of the ceiling of the box type unit as a formwork for concrete casting.

According to a second aspect of the present invention, there is provided a method for constructing a concrete building, comprising separating a concrete formwork / building base material at a predetermined interval and pouring concrete into the interval. The frame for frame is connected with a joint to form a frame-shaped frame, and a flat member is attached to each of the inner and outer surfaces of the frame to form both outer walls,
A rectangular iron plate or a reinforcing bar that temporarily fixes other flat members arranged opposite to the flat member at the time of concrete casting along the outer surface of the flat member constituting the outer wall surface And a vertical guide rail that slidably fits the flanges formed on both sides of the intermediate frame made rectangular with an iron plate to form a concrete formwork and building base material,
The concrete formwork / building base material is disposed in a state where the vertical guide rails are spaced apart from each other by a predetermined distance so as to face each other, and the space between the concrete formwork / building base material extends between the concrete formwork / building base materials. A horizontal reinforcing bar having a width and a predetermined height, and a horizontal reinforcing bar is inserted through an opening of the intermediate frame having a plurality of openings serving as a filling port for concrete while allowing a horizontal reinforcing bar to be inserted in multiple layers. At the same time, a prefabricated assembly reinforcing bar formed by arranging a vertical reinforcing bar so as to intersect with the horizontal reinforcing bar and welding the intersection is inserted into the vertical guide rail by inserting a flange portion of an intermediate frame from an upper end thereof. After arranging between the concrete formwork and building base materials, the space between the concrete formwork and base materials is formed on the load-bearing wall by casting concrete.

[0009]

According to the method for constructing a concrete building according to the first aspect, for example, the vertical guide rails of a box type unit formed in the size of a living room of a dwelling are arranged in a state where they are separated by a predetermined distance and face each other. After inserting the prefabricated assembling rebar into the space formed between the box type units,
A concrete bearing wall can be formed by casting concrete. The prefabricated rebar is formed by arranging an intermediate frame at a predetermined position, arranging horizontal reinforcing bars in multiple layers in communication with the opening thereof, and arranging vertical reinforcing bars between the intermediate frames. Then, the box-type unit is expanded in the upper floor or in the adjacent direction while being left in the frame. In this case, since the box type units are connected to each other by the intermediate frame, they are not deformed even by concrete driving, so that a reinforcing member or the like is not required, and the form does not need to be dismantled. If the inside of the box-type unit is only the inner wall base material made of a flat member, a cloth or the like is directly applied to the inner wall base material to make a decorative finish. In addition, if the inside of the box-type unit is provided with interior work, internal arrangement materials, and the like, a room or the like will be completed each time. As described above, since there is no reinforcement or demolition work of the formwork and the interior work can be performed even before the concrete is cast, or the interior work can be omitted, the construction period can be greatly reduced.

In the separator according to the second aspect, for example, the vertical guide rails of the concrete formwork / building base material formed to have the size of the entire boundary wall of one dwelling are arranged so as to be spaced apart from each other by a predetermined distance so as to face each other. After inserting the prefabricated assembling rebar into the space formed between the concrete formwork and building base materials, the bearing wall can be formed by pouring concrete. The prefabricated rebar is formed in the same manner as described above. In this case, since the concrete formwork and building base materials are connected to each other by the intermediate frame, they are not deformed by the concrete driving. While the interior work is performed while leaving the concrete formwork building base material as it is, the fixing force is sufficient because the vertical guide rails are embedded in the skeleton. In the interior work, a planar member attached to the inner surface of a concrete formwork / building base material is used as an inner wall base material, and a cloth or the like is directly applied to the inner wall base material for decorative finishing. As described above, since there is no reinforcing work or dismantling work of the formwork, and after the panel is installed, the interior work can be performed even before the concrete is poured, so that the construction period can be greatly reduced.

The auxiliary vertical frame 15a and the auxiliary support frame 16 between the four
a will be erected.

A veneer outer plate 2 is stretched as a flat plate member on at least the outer surface of the frame 1. In this case, a flat plate member to which a cloth is attached in advance is stretched on the inner wall side. It may be finished, or when used as a living room, a closet, lighting, and piping may be attached.

Further, a vertical guide rail 3 for inserting a prefabricated rebar is projected from the outer plate 2 so as to protrude outside. As shown in FIGS. 1 and 7, the vertical guide rail 3 is made of a lightweight lip channel steel extending in the vertical direction as a guide frame 30, and a mounting plate 31 is integrally provided on the rear surface of the guide frame 30. The mounting plate portion 31 is sandwiched between lip channel steels 19 provided back to back between the upper and lower horizontal frames 14 of the framework frame.

The outer plate 2 is stretched on the inner and outer surfaces of the frame 1. It is possible to assemble with a simple operation, to achieve a squareness and a parallelism easily, and to reduce the weight.

Next, a method of constructing an apartment house using the box type unit U will be described with reference to FIGS. In this construction method, a plurality of box-type units U are arranged and assembled, and a space S between adjacent box-type units U, U is formed on a load-bearing wall.

That is, the box-shaped units U are installed with a predetermined distance therebetween, and the prefabricated pre-assembled reinforcing bars 4 are mounted on the vertical guide rails in the space S between the adjacent box-shaped units U, U. The space S is formed on the load-bearing wall by placing concrete after fitting along 3. In this case, the reinforcing bar may be inserted into the intermediate frame while gradually arranging the reinforcing bar. In addition, the box-type unit U may be one that has been installed up to the interior in advance.

The prefabricated rebar 4 has a plate-shaped intermediate frame 40 which is disposed in accordance with the position where the vertical guide rail 3 is disposed. The intermediate frame 40 has flange portions 41 inserted into the guide rail frame 30 of the vertical guide rail 3 protruding from both sides as longitudinal locking edges on both side edges thereof, and a plurality of flange portions at the middle portion. The openings 42 are formed in parallel in the vertical direction, and a reinforcing bar receiving portion 43 is formed at the bottom edge of the opening 42. In this case, the intermediate frame 40 and the vertical guide rail 3 have a function as a separator, and the cast concrete is completely filled by the openings 42 even if the intermediate frame 40 is plate-shaped.

The horizontal reinforcing bars 44 pass through the openings 42 of the intermediate frame 40 and are supported by the reinforcing bar receiving portions 43.
Are arranged, and a vertical reinforcing bar 45 is arranged so as to intersect with the horizontal reinforcing bar 44, and the vertical and horizontal reinforcing bars 44, 45 are welded at the intersection, thereby forming a prefabricated assembled reinforcing bar.

Therefore, as shown in FIG. 10, the flanges 41, 41 of the intermediate frame 40 are connected to the vertical guide rails 3, 3.
Of the prefabricated assembling rebar 4 can be fitted into the space S between the adjacent box-type units U, U.

In order to prevent the prefabricated rebar 4 fitted in the space S as described above from being cut off from the other prefabricated rebars, as shown in FIG. The vertical reinforcing bar 5 is erected on F, the lower end of the vertical reinforcing bar 45 is overlapped with the basic vertical reinforcing bar 5, and the upper end of the vertical reinforcing bar 45 is extended upward from the upper surface of the box type unit U. The vertically extending reinforcing bar portion 45a is made to overlap the lower end portion of another prefabricated assembling reinforcing bar (not shown) installed on the upper stage. Also, the horizontal reinforcing bar 44 of the prefabricated assembled reinforcing bar 4 has both ends extended laterally from the side surface of the box-shaped unit U, and the horizontal extended reinforcing bar portion 44a is installed on the side of another prefabricated assembled reinforcing bar. 12 (not shown), and
As shown in FIG. 1, a horizontal reinforcing bar 6 is provided on a basic concrete column T so as to protrude laterally.
Are made to overlap.

Therefore, according to this construction method, the outer plate 2 of the box-shaped unit U functions as a form panel in the case of formwork, and the outer plate 2 is stretched on the frame 1. The frame 1 functions as a support for supporting the outer plate 2. Therefore, there is no need for a form panel, and there is no need to use columns, braces, etc. in addition to separators and metal fittings, so that assembling and dismantling of the form can be omitted. Then, the box-type unit 1 is left as it is in the skeleton, and is newly expanded in the adjacent direction and the upper floor direction, so that a general reinforced concrete building can be formed.

Further, since it is only necessary to assemble the prefabricated assembling rebar 4 in another place in advance and fit it into the space S between the box-shaped units U, U, the assembling of the prefabricated assembling rebar can be simplified. When fitting the prefabricated assembling rebar, the flange portion 41 is connected to the vertical guide rail 3,
3, the fitting operation can be performed easily and reliably.

Next, a second embodiment will be described. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. In this embodiment, a concrete formwork is also assembled into a shape similar to that of the conventional formwork method using a concrete formwork and building base material to form a boundary wall. FIG. 13 is an explanatory view showing a concrete formwork / building base material 7A.
Is a frame.

The framing frame 70 forms the skeleton of the concrete formwork / building base material 7A having the entire length of the boundary wall of one dwelling, and the left end side connection in the figure forms an outer wall perpendicular to the boundary wall end. The joint 10c is used in order to connect a concrete formwork / building base material panel 7B to be connected in succession. A joint 10f shown in FIG. 14 is used for the right end side connection. This joint 10
f indicates that the horizontal connection portion 12 and the vertical connection portion 13 are provided in an orthogonal state (L shape). Also, horizontal frame 1
4 are extended by a joint 10g shown in FIG. The joint 10g is an intermediate joint, which is added when the concrete formwork / building base material 7A is required to be longer than the frame. The joint 10g also has a vertical connection portion 13 on which the auxiliary support frame 16a is erected. .

Also in this case, the outer frame 2 is stretched on both sides of the frame 70, and in this case, the cloth may be pasted on the inner wall side in advance. The outer plate 2
A vertical guide rail 3 protrudes from the outer wall of the vehicle.

This concrete formwork / building base material 7A
After the vertical guide rails 3 oppose each other and are separated from each other in a state of being separated according to the wall thickness, the prefabricated assembling reinforcing bar 4 is inserted, so that concrete can be immediately poured. In the drawing, 7C is for forming the outer surface side of the outer wall formwork with respect to the concrete formwork / building base material 7B.
A concrete panel 71 assembled in a flat plate shape using f or 10 g is continuously provided, and is assembled using a normal separator or support. In the figure, reference numeral 71a denotes a panel joint fitting provided with a gap enough to pass a separate screw portion 40c described later between the panels 71, and reference numeral 71b denotes a pin for locking a notch 71c provided in the joint fitting 71a. This is retrofitted to joints 10f and 10g. Since there is no vertical guide rail on the outer side panel of the outer wall form, an attachment 40a shown in FIG. 16 is used for the intermediate frame 40 of the prefabricated assembling reinforcing bar 4. In this case, a standard joint or a flat member can be used for the concrete panel 71, and the concrete panel 71 can be dismantled and diverted after the concrete curing, which is very economical.

The attachment 40a has a clip portion 40b which is inserted into and fixed to the intermediate frame 40 and a separate screw portion 40 which is inserted into the concrete panel 71 and fastened on the outside thereof.
c, and the separate screw portion 40c is provided with a cut portion 40d so as to be cut off when the outer wall side formwork 7C is disassembled. In this embodiment, as shown in FIG. 17, a plaster board 72 is attached to the inner surface of the outer wall-side formwork 7C, a tile 73 is temporarily attached to the inner surface of the plaster board, and joints are provided in advance. In this case, once the concrete has been poured, the tiled outer wall finish is completed.

In the form of the panel assembling, after the concrete is cast as described above, the outer form 7C of the form for the outer wall is disassembled, but the other forms are kept as they are as in the box form unit. Will be left inside. In this case, since no support work or the like is required on the indoor side, the interior work can be performed immediately after the formwork is installed.

FIGS. 20 to 23 show partitioning joints 10h, 10i, 10j, and 10k, respectively. The connecting portion 13a for inserting the support frame is formed in a rectangular cylindrical shape, and the connection for the vertical frame is provided. The portion 11a and the connecting portion 12a for the horizontal frame are all formed in a substantially U-shape with an open top. This joint 10h, 10i, 10
A partition wall may be formed by j and 10k, and may be set at a predetermined position at the same time when a formwork for an outer wall or a boundary wall is installed.

The embodiments of the present invention have been described above.
The specific configuration of the present invention is not limited to this embodiment, and any change in design or the like without departing from the gist of the present invention is included in the present invention.

For example, the box-type unit U and the building base material 7A that also serves as a concrete formwork can be mixed without being used separately.

Although the intermediate frame of the separator has been described in the form of a plate, the shape is arbitrary. For example, the intermediate frame of the separator may be formed in a frame shape by connecting flange portions formed of plates with reinforcing steel. Further, when a conventional concrete panel and a concrete formwork / building base material are mixed to construct an outer wall formwork, one of the flange portions is not required, and therefore, one of the intermediate frames is provided as shown in FIG. Alternatively, a reinforcing bar may be fixed instead of the flange portion. In the figure, 74 is a wooden cone, 75 is a cover for covering a joint between concrete panels, and 76 is a concave portion for receiving a horizontal reinforcing bar when forming a prefabricated assembled reinforcing bar.

FIG. 19 is a sectional view showing another embodiment of the vertical guide rail 3. This vertical guide rail 3 uses a substantially U-shaped profile member extending in the vertical direction as a guide frame 30a,
The guide frame 30a is fixed to the projecting side edge of the mounting plate 31 by spot welding or the like. Along with this, flange portions 41 formed on both side edges of the intermediate frame 40 of the prefabricated assembling rebar 4 are formed to protrude to one side. On the opposite side of the protruding side of the mounting plate portion 31, there are provided folded portions 31a which are alternately engaged with the lightweight channel steel at predetermined intervals. On this side, both the vertical and horizontal reinforcing bars are arranged as a single bar.

Although the construction method has been described for constructing an apartment house, the present invention is not limited to this and can be applied to construction of other concrete buildings.

The shape of the joint for forming the frame and the frame for the frame are arbitrary. For example, FIGS.
As shown in (1), a weight reduction hole, a reinforcing rib, and the like can be provided. Also, the material and the like are arbitrary.

[0040]

As described above, according to the method for constructing a reinforced concrete building according to claim 1 of the present invention,
Because the method described above, it is possible to construct a skeleton by providing a concrete boundary wall and an outer wall without providing a concrete formwork with a form panel, and it is possible to simultaneously provide a plurality of chambers in the skeleton, thereby shortening the construction period, Effects such as cost reduction can be obtained. In addition, when a plurality of the intermediate frames are juxtaposed and horizontal reinforcing bars are inserted in multiple layers and combined with vertical reinforcing bars to provide a prefabricated assembled reinforcing bar, the molds are inserted later into a narrow concrete formwork. Immediately in the state where the bar is arranged in the frame. Also, by forming a unit having a predetermined size and arranging a plurality of the units at intervals corresponding to the boundary wall formation, the frame frame becomes a support, so that the boundary wall is formed by the outer wall portion of the unit. Formwork can be formed. By leaving the box-type unit in the frame, it is possible to finish the interior of the room immediately by performing interior construction such as cloth attachment using the inner wall as a base material. In addition, since no support work is required, interior work can be performed at any time.

In the method for constructing a concrete building according to the second aspect of the present invention, since the above method is adopted, a concrete formwork / building base material that forms a wall of the size of a single house is formed as an integral structure. Therefore, it is not necessary to provide any support to reinforce the conventional formwork panel, and it is possible to arrange reinforcing bars in the formwork even after the concrete formwork / building base material is installed, The formwork can be firmly held by the intermediate frame at the same time as the streaks. In addition, by leaving the formwork panel in the frame without removing it, the dismantling work is not required, and the interior work such as cross-pasting is performed immediately without the need to newly install an interior base material. And the like.
By forming a panel of a required size, a seam in a plane, which has been conventionally formed in many cases, cannot be formed at the time of forming a formwork. Therefore, a support work for the seam is not required and misalignment does not occur.
