DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure constituting, for example, a wall of a building.

[0002]

2. Description of the Related Art As one of wall construction methods for constructing a wall of a building or the like, a so-called formwork in which rectangular formwork blocks are used and laid vertically and horizontally on a plane. Block construction is generally known.

FIGS. 10 and 11 show an outline of a general construction method of a building wall in this type of formwork block construction. In the figure, reference numeral 1 designates a basic form block (H-shaped block) made of concrete. The form block 1 is composed of a pair of rectangular panel portions 2, 3 arranged in parallel with each other at a predetermined interval. The panel portions 2 and 3 are integrally connected to each other by plate-shaped rib portions 4 on their opposing surfaces to form a substantially H shape.

The height of the rib part 4 is the panel part 2,
3 is set lower than the height h, and is disposed apart from each other on the inner side in the longitudinal direction, whereby the hollow portion through which the vertical streaks 5 pass through the inside and the left and right butted portions is The space through which the horizontal streaks 6 pass is formed in the upper part, respectively.

Then, the formwork block 1 is laid up and down and left and right while arranging a vertical streak 5 and a horizontal streak 6 inside, and a cast-in-place concrete 7 is poured into the space and the hollow portion to form the vertical streak 5. By embedding the horizontal stripes 6 in the concrete 7, the walls of the building are constructed.

As the mold block, in addition to the above-described H-shaped block, a Z-shaped block, an L-shaped block and the like are widely used.

[0007]

However, all of the above-mentioned conventional wall structures are mainly constituted by concrete blocks, and concrete is generally inferior in heat insulation performance. In the case of a covered heat insulating structure, it is necessary to separately prepare a heat insulating material and attach it around the wall so as to surround the entire building.

[0008] In addition, the concrete form block,
At present, the size is limited in order to facilitate transportation and handling. For example, in the case of the form block (H-shaped block) shown in FIG. 10, the length 1 is 390 mm.
The height h is 190 mm and the width t is 150.180.2
Since each is set (standardized) to 00 mm, more formwork blocks are required, and it takes a considerable amount of time to construct the wall.

Further, in the above-mentioned conventional wall structure, since the surface of the concrete form block is exposed, the exposed surface can be covered and hidden by a decorative plate such as an exterior panel or an interior panel, or beside the form block. At present, these operations are generally quite difficult even if an air passage is to be formed.

[0010] In view of the above, the present invention can be constructed using a lightweight form block having excellent heat insulation performance, and furthermore, the exposed surface of the form block can be easily covered with a plate. It is an object of the present invention to provide an air passage that can easily form an air passage between a mold block and a mold block.

[0011]

In order to achieve the above-mentioned object, a wall structure according to the present invention comprises a pair of panel portions which are arranged substantially parallel to each other and connected to each other at their opposing surfaces. A form block integrally formed with a resin foam with a rib portion is laid out on one surface, and a joining piece of the form portion extends across the panel portion and a mounting piece at both ends extends on the joint surface of the form block. It is characterized in that a separator protruding outward is interposed.

[0012] Here, on the upper and lower end surfaces of the panel portion, convex portions facing in the thickness direction when they are vertically overlapped are formed, and a step portion located between the convex portions is formed on the separator. A plate may be attached to the protruding end of the separator to form an air passage between the plate and the panel.

[0013]

According to the present invention constructed as described above, by forming the pair of panel portions and the rib portions integrally with the resin foam, the weight is reduced and the form block itself has high heat insulating performance. By laying the form blocks on one side, a wall having excellent heat insulating properties can be constructed without separately preparing a heat insulating material. Moreover, the mounting pieces of the separator interposed with the mounting pieces at both ends protruding outward at the joints of the formwork blocks can be used as mounting tools such as plate materials or square materials. An air passage can be formed between the plate member and the panel portion by mounting the panel portion on one surface with a predetermined space therebetween.

[0014]

On the other hand, on the lower end surfaces of the panel portions 11 and 12, a first convex portion 32 having the same predetermined pitch p ₂ and the same length b as the upper end surface is provided along the length direction. And the second
Are alternately formed in two rows in the thickness direction.

The first convex portion 32 located on the outer side is formed in the same shape as the second convex portion 31, and the second convex portion 33 located on the inner side is formed in the same shape as the first convex portion 30. The raised surfaces 32a, 33a on the sides facing each other of the convex portions 32, 33 and the raised surfaces 32b on both sides in the longitudinal direction,
33b is a tapered surface that gradually expands outward along the height direction, that is, the lengths of the projections 32 and 33 gradually increase downward, and their widths gradually decrease downward. It is becoming thicker.

On the upper and lower end surfaces of each of the panel portions 11 and 12, the first convex portions 30 and 32 located outside and the second convex portions 31 and 33 located inside have the same length. b (= p _2/2) only partial is arranged in a state of out of phase.

Thus, when the form blocks 10 are stacked in the up-down direction, the first convex portions 30 outside the form blocks 10 located below are fixed to the form blocks 1 located above.
0 of the second convex portion 33 of the mold block 10 in which the rising surface 30a of the convex portion 30 of the mold block 10 located below and between the first convex portions 32 outside the It faces the rising surface 33a.

On the other hand, the second convex portion 31 inside the lower mold block 10 enters between the second convex portions 33 inside the upper mold block 10, and
The rising surface 31a of the convex portion 31 located below is configured to face the rising surface 32a of the first convex portion 32 of the formwork block 10 located above.

At this time, as shown in FIG. 5, the form block 10 has a width T _{2 at} its lower end larger than a width T _{1 at its} upper end (T ₂ > T ₁ ), and when the form blocks 10 are vertically overlapped. First convex portion 3 of formwork block 10 located below

And the rising surface 33a of the second projection 33 is the rising surface 31a of the second projection 31 of the form block 10 located below.
And the rising surface 32a of the second projection 32 of the form block 10 located above is configured to engage with each other.

Thus, each of the projections 30, 31, 32, 3
3 is the three rising surfaces 30a, 30b, 30b, 3
1a, 31b, 31b, 32a, 32b, 32b, 33
a, 33b, 33b engage with each other to perform mutual positioning, and furthermore, these rising surfaces 30a, 30b,
By making the tapered surfaces 31a, 31b, 32a, 32b, 33a, 33b gradually expand outward,
The connection between the two can be performed by ensuring this engagement.

Then, as described above, the lower 1
2/3 of one form block 10 located above the upper end surface of each form block 10 and 1/1 of the other form blocks 10
3 so that each of the protrusions 30, 3
1,32,33 are provided a total of six equivalent of multiples of 3 at a predetermined pitch p _2.

When the mold blocks 10 are stacked in this manner, 1/3 or 2/3 of the formwork blocks 10 project to the side, so that the panel sections 1 and 12 on the surface of the panel sections 11 and 12 are formed.
At positions where the lengths 1 and 12 are equally divided into three in the length direction, score lines 3
4 are provided, and cut along the cut lines 34 so that the ends are aligned.

The mold block 10 can be formed, for example, by forming in a mold, by post-processing, and further by cutting. Further, as shown in detail in FIG. 2, a concave portion 35 having a depth corresponding to the thickness of the separator 40 for inserting a metal separator 40 is formed in each of the upper end surfaces of the panel portions 11 and 12, as shown in detail in FIG. It is formed along the thickness direction.

The separator 40 is provided on the panel parts 11 and 1
When the cast-in-place concrete 18 is cast into the inside of the space between the two, this gap is kept constant, and also serves as a fixture for a plate material or a square material. Is formed by bending.

That is, in the separator 40, a flat portion 43 which rises one step via a step portion 42 is formed at both ends of a connecting plate portion 41 having a length between the convex portions 30 facing each other. A mounting piece 44 rising upward is integrally connected to the tip of the flat portion 43.

As a result, as described above, when the form blocks 10 are overlapped in the vertical direction, a step d (see FIG. 5) occurs at the joint in the vertical direction. When the concrete 18 is cast, the form block 10 is deformed so as to expand outward due to this force. Then, the rising form surface 33a of the second convex portion 33 provided on the lower end surface of the upper form block 10 comes into contact with the step portion 42 of the separator 40, while the lower form block 10 Rising surface 31 of the second convex portion 31
a and the first convex portion 32 of the mold block 10 located above
Are pressed against each other, and the interaction between them causes the form block 10 to be flush.

Further, when the cast-in-place concrete 18 is poured into the form block 10, a projection is formed on a part of the form block 10 due to the internal pressure of the concrete 18,
Although the flatness here may not be ensured, since the length of the separator 40 is not deformed by the internal pressure,
The plane formed by the mounting pieces 44 of the separator 40 is always constant.

The distance between the step portion 42 and the mounting piece 44 is larger than the thickness of the panel portions 11, 12.
The length of the mounting piece 44 is set to be exposed to the outside of the panel portions 11 and 12.

A plurality of notches 45 are formed in the separator 40 to allow the vertical stripes 16 to pass through in the vertical direction. As described above, the mounting piece 44 of the separator 40 is configured to protrude outward from the panel portions 11 and 12, and the plate pieces such as the exterior panel 50 and the interior board 51 are formed via the mounting piece 44. It can be mounted. That is, for example, a female screw is engraved on the mounting piece 44, and the exterior plate 50 is
And the mounting of the interior plate 51, thereby forming the form block 1
0 is not exposed to the outside.

At this time, by attaching the exterior plate 50 and the interior plate 51 to one surface, the space between the exterior plate 50 and the panel portion 11 and between the interior plate 51 and the panel portion 12 can be increased.
Air passages 52 and 53 through which air flows are formed.

The phantom line (two-dot chain line) is shown in FIGS.
As shown in the figure, the body edge 60 is fixed to the attachment piece 44, and the nail
0 and the interior plate 51 may be attached.

In this embodiment, the form block 10
The exterior plate 50 and the interior plate 51 are attached to both outer surfaces of
Although an example is shown in which the air passages 52 and 53 are formed on both the indoor side and the outdoor side, only one of them may be provided.

Further, the separator 40 has a vertical streak 16
Is provided, but when it is located above (or below) the rib portion 13 of the formwork block 10, there is no need to insert the vertical streaks 16, so FIG. As shown, a separator 40a having no notch groove 44 therein may be used.

As shown in FIG. 7, a rising piece 46 that rises vertically to the end face of the connecting plate portion 41 is integrally connected,
A second notch groove 47 extending in a direction orthogonal to the notch groove 45 is provided above the rising piece 46 so as to form a separator 40b.
The horizontal streak 17 is inserted through the second notch groove, so that the vertical streak 16 and the horizontal streak 17 are
0b may be bound.

According to this embodiment, the vertical streaks 16 and the horizontal streaks 17 are arranged inside, and the separator 40 is provided on the upper and lower joint surfaces.
The formwork blocks 10 are stacked vertically, horizontally, and
Concrete 18 is poured into the hollow portion 14 and the space 15, and thereafter, the exterior plate 50 and the exterior plate 50 are attached via the attachment piece 44 of the separator 40 or the body edge 60 fixed to the attachment piece 44. By attaching the interior plate 51, a wall having ventilation passages 52 and 53 on the indoor side and the outdoor side can be constructed.

Thus, the mold block 1 made of a resin foam can be formed in substantially the same manner as a normal mold block.
O can be constructed quickly and easily using a fairly large formwork block, because it is lightweight and has a high insulation performance itself.

The exterior plate 50 and the interior plate 51 are attached via the attachment piece 44 of the separator 40 to prevent the mold block 10 made of a resin foam from being exposed to the outside, and In addition, a wall provided with air passages 52 and 53 on the outdoor side can be formed.
