Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As a wall construction method for building a wall of a building,
It is known that a rectangular flat plate-shaped wall panel is used as a concrete formwork, and after pouring in-situ concrete as a filling material between the wall panels, the wall is constructed without removing the wall panels. Has been.

An example of the wall structure of a building constructed in this way is shown in FIG. In the wall structure shown in the figure, a rectangular flat plate-shaped wall panel 1 is arranged in parallel at a predetermined distance according to the thickness of concrete, and if necessary, a reinforcing bar composed of vertical bars 2 and horizontal bars 3 After that, the cast-in-place concrete 4 is placed between the wall panels 1 to bury the reinforcing bar inside the concrete 4, and the exposed surface of the concrete 4 is covered with a wall material such as a wall board 5 or the like. It was built by.

Here, the interval between the wall panels 1 facing each other is kept constant by, for example, disposing the separator 6 shown in FIG. 9 therein. That is, when the wall panels 1 are arranged side by side, perforations are preliminarily formed at predetermined positions facing each other, and the threaded portions 7 at both ends of the separator 6 are inserted into the perforations, thereby providing a large diameter on both sides. The outer surfaces of the bridges 8 and 9 are brought into contact with the facing surfaces of the panel 1, and a nut (not shown) is screwed onto the screw portion 7.

Then, in order to erase the mark of the screw portion 7,
As described above, the exposed surface of the concrete 4 is covered with a wall plate (wall material) 5 such as a gypsum board via a plaster adhesive, or a coating material (wall material) such as plaster or resin mortar.
Is widely applied.

[0006]

However, the above-mentioned conventional wall structure generally has poor heat insulation performance. Therefore, when the whole building is covered with a heat insulation material, a heat insulation material is separately prepared. , It was necessary to mount it around the wall so as to surround the entire building.

Moreover, when an application material such as cement mortar is used as the wall material to apply this to the exposed surface of the wall panel, the surface of the wall panel is flat and relatively slippery, and the application material is retained. Since the force is considerably weak, the coating material (wall material) cannot be peeled off too thick in order to prevent the coating material (wall material) from being peeled off, and thus cracks and unevenness are likely to occur. In order to prevent this, as described above, there is a problem that it is necessary to use resin mortar which is considerably expensive.

In view of the above, the present invention can be constructed by using a wall panel that is lightweight, inexpensive, and has excellent heat insulation performance, and that this exposed surface can be easily covered with a wall material such as cement mortar. The purpose is to provide what has been done.

[0009]

In order to achieve the above object, a wall structure according to the present invention is made of a resin foam, and a wall is formed by gradually sloping inwardly on at least one side of the wall. The rectangular flat plate-shaped wall panels provided with the wall material application surface, in which a large number of base grooves for holding the material are arranged over substantially the entire area, are arranged side by side at a predetermined distance with the wall material application surface as the outside. A filling material is filled between the wall panels, and the wall material application surface is coated with the wall material to construct the structure.

[0010] Here, a reinforcing bar composed of a vertical streak and a horizontal streak is provided between the wall panels juxtaposed at a predetermined distance from each other, and the vertical streak and the horizontal streak are embedded in the filling material, or the base groove is formed. ,
Formed in a shape that opens upward, such that the peripheral wall surface of the base groove and the plane formed by the wall material application surface intersect at an acute angle, or on the facing surfaces that face each other when the wall panels are arranged side by side, It is also possible to form at least one of a convex portion and a concave portion that linearly extend over the entire length or width.

[0011]

According to the present invention configured as described above, the wall panel is formed of the resin foam, so that the wall panel itself has high heat insulation performance, and the wall of the outer surface of at least one of the wall panels is provided. Securely hold the wall material by the wall panel itself by letting a part of the wall material applied to the wall material application surface enter into a large number of base grooves provided almost all over the material application surface. You can

m) board or 2 × 6 (600 mm × 1800 mm) board, which also has a role as a concrete formwork.

Here, the resin foam constituting the wall panel 10 is formed by foaming a synthetic resin such as polystyrene foam, polyurethane foam, polyvinyl chloride foam, or polyolefin foam. The expansion ratio is, for example, 5 to 100 times, preferably 2
It is 0 to 80 times, more preferably about 30 to 70 times.

As described above, by constructing the wall panel 10 with the resin foam, the wall panel 10 itself has a high heat insulating property and a sound absorbing effect, the weight is reduced, the corrosion is further prevented, and the cost is reduced. be able to.

One side of the wall panel 10 is a wall material application surface 1
The wall material application surface 11 has a large number of base grooves 12 formed in parallel over substantially the entire area thereof. The wall panels 10 are arranged side by side with the wall material application surfaces 11 facing each other at a predetermined distance from each other.

The space between the wall panels 10 is defined by the wall panel 1
When 0s are arranged side by side, holes are preliminarily formed at predetermined positions facing each other, and the separator 6 shown in FIG. The vertical bar 2 and the horizontal bar 3 are arranged on the.

The base groove 12 surrounds the periphery of the taper surface 13 that gradually inclines inwardly toward the lower side in a substantially U-shape in plan view, which is opened upward by a peripheral wall surface 14 rising in the thickness direction. Is configured.

The peripheral wall surface 14 is composed of a side surface portion 14a which gradually expands upward on both sides, and a bottom surface portion 14b which connects the lower end of the side wall portion 14a to the side wall portion 14a continuously. The gutter 12 has an isosceles trapezoidal shape that widens upward and gradually becomes deeper toward the lower side.
The bottom surface portion 14b of No. 4 rises in the thickness direction at the narrowest and deepest position of the base groove 12.

Then, the wall panels 10 are arranged side by side at a predetermined distance, and a filling material such as cast-in-place concrete 4 is filled between the wall panels 10, and then the wall material application surface 11 is coated with, for example, cement mortar 15. A wall material such as is applied to build the wall. At this time, a part of the cement mortar 15 enters the inside of the base groove 12, so that the cement mortar 15 is prevented from flowing downward. Is sure to hold.

Cement mortar 1 with this base groove 12
In order to ensure the retention of No. 5, the peripheral wall surface 14 of the base groove 12 and the plane formed by the wall material application surface 11 intersect each other at an acute angle.

That is, as shown in FIGS. 3 and 4, the angle α between the bottom surface portion 14b of the peripheral wall surface 14 and the wall material application surface 11 and the side surface portion 14a of the peripheral wall surface 14 and the wall material application surface 11 are defined. The formed angles β are set to about 70 ° (α = β = 70 °), respectively, whereby a pocket-shaped groove portion is formed around the base groove 12.

As a result, the cement mortar 15 applied to the wall material application surface 11 of the wall panel 10 easily flows into the pocket-shaped groove portion formed around the base groove 12 from above, and moreover Escape from here is prevented by the wall surface 14.

The angles α and β are preferably about 30 ° to 90 °, and particularly preferably about 45 ° to 85 °. The wall panel 10 can be formed by, for example, in-mold molding, post-processing using a roasting iron having an outer shape along the shape of the base groove 12, and further cutting.

According to this embodiment, the wall panels 10 are laid side by side on the foundation or the like with a predetermined space therebetween, and the separators 6 and the like are arranged inside the wall panels 10 to keep the space between the wall panels 10 constant. At the same time, if necessary, a reinforcing bar composed of vertical bars 2 and horizontal bars 3 is provided. For example, vertical flaps and horizontal flaps are arranged on this side as in the normal formwork construction method, and tightening fasteners are tightened. By holding this state.

Then, a cast-in-place concrete 6 is placed between the wall panels 10, and then a wall material such as cement mortar 15 is applied to the wall material application surface 11 of the wall panel 10 to construct a wall. can do.

At this time, since the cement mortar 15 is held in a state that a part of the cement mortar 15 has entered the inside of the base groove 12 formed in the wall material application surface 11, a considerably strong holding force is obtained and, for example, a wall. Even if cement mortar 15 is used as the material, it can be reliably held with a considerably large wall thickness.

Moreover, the wall panel 10 made of resin foam is used.
Since it itself has high heat insulation performance, the wall of the heat insulation structure can be constructed quickly, easily and inexpensively. In addition, in the above-described embodiment, the peripheral wall surface 14 is used as the base groove 12.
An example is shown in which the wall coating surface 11 and the wall material application surface 11 intersect each other at an acute angle. However, as shown in FIG.
Of the bottom surface 14b is a horizontal surface, and an upward protrusion 14c is provided at the end portion on the front surface side, or as shown in FIG.
It is possible to prevent the wall material such as the cement mortar 15 from flowing downward by providing the projections 14c and the recesses 14d.

As shown in FIG. 6 (a), the base groove 12 has a rectangular shape in which the side wall portion 14a rises substantially vertically, or as shown in FIG. 6 (b), the side wall portion 14a.
The bottom surface 14b may have an arc shape as shown in FIG. 7C, or may have an arc shape as shown in FIG.
As shown in, the bottom surface portion 14b is extended linearly over substantially the entire length of the wall panel 10, and further, although not shown,
It can be formed in any shape, such as a semicircular shape as a whole.

Further, in the above embodiment, the base groove 12
Are arranged in parallel, that is, at equal intervals in the vertical and horizontal directions, but it goes without saying that they may be arranged in a staggered manner or randomly.

The same applies hereinafter. Also,
Although the above-mentioned embodiment shows an example in which the wall is constructed by using the mold panel 10 having the same shape, the resin foam may be exposed to the outside, for example, the inner wall of the warehouse. In this case, it is possible to construct a wall by combining a flat form panel without a wall material application surface with the form panel 10.

FIG. 7 shows a modification of the wall panel.
This wall panel 10a is provided with a convex portion 15 and a concave portion 16 which extend on substantially the entire length in the vertical direction on the back surface side, and when the cast-in-place concrete 4 is cast, the concrete 4 and the wall panel 10a are joined together. Is a certain thing. That is, the convex portion 15 is embedded inside the concrete 4 cast on the back surface side of the panel, and the cast concrete 4 further enters the concave portion 16.

Further, the convex portion 15 functions as a rib to reinforce the wall panel 10a, and the concave portion 16 is
By passing the vertical stripes 2 through this, the wall panel 10a
The connection with the concrete 4 is made more reliable, but it goes without saying that one or both of them may be omitted.
