Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to the structure of wall formwork used for forming walls of concrete structures.

<Prior Art> Normally, in order to form the walls of a concrete structure, a formwork consisting of a pair of weir plates is formed on site. In other words, a weir plate is erected on one side in advance, wall reinforcements are arranged on this, a predetermined wall thickness is secured using separators, etc., and another weir plate is erected on the other side to form a formwork. . Concrete is poured into this formwork, and after the desired strength has been achieved, the formwork is removed and the interior and exterior finishes are applied to the wall. A separator is passed through and held between the weir plates, and shoring made of vertical and horizontal battens is provided on the outer surface of the weir plates.

<Problem to be Solved by the Invention> In conventional building wall formwork, as mentioned above, holes for attaching separators are drilled in the formwork itself, and embedded bolts are provided for attaching various types of shoring. If the formwork itself is used as a waste formwork, additional curing work such as backfilling the holes and removing the embedded bolts will be required. Moreover, in this case, if the discarded formwork is finished internally and externally, many problems arise, such as damage to the finished surface.

Means for Solving the Problems> The present invention has been made to solve the above problems, and the present invention has been made in order to solve the above problems. and fixing a plurality of width stop reinforcements to the longitudinal reinforcement, attaching bar-shaped vertical reinforcement to the width stop reinforcement in a state facing the longitudinal reinforcement, and arranging horizontal reinforcement in a state included in the width stop reinforcement, Another single-sided panel that constitutes a wall is disposed in a state facing the single-sided panel and via the stop bars.

(Function) On the inside of one side panel, a plurality of width stop bars are installed as vertical bars, and on the other hand, since the other single side panel is attached via the width stop bars, it is possible to support the one side panel and the other single side panels from the outside. Even if the concrete is not supported using concrete, the bulge caused by the lateral pressure of pouring concrete will be prevented by the stop bars.

As a result, even if a single-sided panel is finished with inner and outer walls, it is possible to provide a building wall formwork, which is a waste formwork suitable for forming a building wall, without staining the finished surfaces.

<Example> The structure of the wall form for a building of the present invention and the construction of a wall for a building using this wall form will be described below based on the drawings.

FIG. 1 is a schematic vertical cross-sectional view showing the structure of a formwork according to the present invention, and FIG. 2 is a schematic horizontal cross-sectional view thereof.

The building wall formwork consists of one side panel 1 and another single side panel 2, which are integrated with poured concrete to form a wall. Vertical stripes 3, rod-shaped longitudinal stripes 6, and horizontal stripes 5.7 are provided between both single-sided panels 1.2, respectively. The single-sided panel 1 has a substrate 1 as shown in FIG.
1, and a plurality of vertical protrusions 12 (in the illustrated example, a total of three at both ends and approximately at the center) are provided on the inner surface thereof as necessary. This vertical protrusion 12 is for connection and reinforcement, and is formed to have approximately the same thickness as the substrate 11. In addition, horizontal reinforcement insertion holes 13 are bored in the vertical protrusion 12 at predetermined intervals. On the other hand, as shown in FIG. 4, the other single-sided panel 2 also has horizontal protrusions 22 (three in total at the top, bottom, and approximately in the center) extending at predetermined intervals in the horizontal direction relative to the substrate 21 as required. Auxiliary reinforcement insertion holes 23 are also bored in this horizontal protrusion 22 at predetermined intervals.

The single-sided panel 1 and the other single-sided panel 2 are integrally formed from, for example, lightweight aerated concrete material, asbestos cement molding material, or the like. Moreover, when the single-sided panel 1 is used on the exterior wall side, an exterior finish such as mortar finish or tiling is applied, and when the other single-sided panel 2 is used on the interior wall side, an interior finish such as cross-covering is applied. . Moreover, a heat insulating material is provided inside both panels as necessary.

On the other hand, the horizontal reinforcements 5 and 7 and the bar-like vertical reinforcements 6 are made of long reinforcing bars having the same diameter as the main reinforcement 31 of the vertical reinforcement 3, and the auxiliary reinforcements 8 are made of reinforcing bars having approximately the same diameter as the stop bars 4.

Next, the construction of the wall formwork of the present invention will be explained.

As shown in Fig. 6, first, the adjacent vertical ridges 12, 12 of the single-sided panel 1.1 are built in contact with each other.Normally, these single-sided panels 1.1 are erected along the marking line on the foundation. will be placed.

In such a state! As shown in FIG. 87, the vertical strips 3 are temporarily placed on the inner surface side of the single-sided panel 1 along with the vertical ridges 12. As shown in FIG. 8, each vertical protrusion 12, 12...
・Horizontal stripes insertion hole 1: L, 13... and transverse stripes 5, 5...
Insert and fix. The horizontal reinforcement 5 is brought into contact with the corner formed by the upper side 41 of the stop width reinforcement 4 and the main reinforcement 31, and the other horizontal reinforcement 5 is inserted and fixed in a state where it is brought into contact with the lower side 43 and the inner corner of the main reinforcement 31. That is, the transverse reinforcement 5 is disposed so as to be included in the width stop reinforcement 4. The horizontal stripes 5 have a length approximately 1.5 times the width of the outer wall panel 1, and are bound to the vertical strips 3 by wires or the like. As a result, the vertical strips 3 are arranged perpendicularly through the horizontal strips attached to the inner surface of the outer wall panel.

After placing the transverse muscles 5, 5 in each of the width stop muscles 4.

As shown in FIG. 9, a bar-shaped vertical reinforcement 6 is attached to the width stop reinforcement 4 in a state opposite to the vertical reinforcement 3. And as shown in Figure 10 (
(see Fig. 1), the space on the other single-sided panel 2 side formed by the rod-shaped vertical bars 6 and the horizontal sides 42 of the width stop bars 4, that is, the upper side 41 and the horizontal side 4
2 and the corner formed by the lower side 43 and the horizontal side 42 are provided with horizontal stripes 7, 7, respectively. These forest-like longitudinal stripes 6 and horizontal stripes 7

Vertical stripes 3 for the above single-sided panel l. Once the bar-shaped vertical reinforcements 6, horizontal reinforcements 5, 5, -7, '7, etc. are incorporated as shown in Fig. 11, another single-sided panel 2 is placed on the horizontal side 42 side of the stop reinforcement 4 and built . In the single-sided panel 2, the horizontal protrusions 22 are orthogonal to and opposite to the longitudinal protrusions 12 of the single-sided panel l, and the horizontal sides 42 of the width stop bars 4 are between the horizontal protrusions 22, 22. Placed in inserted state.

Next, the auxiliary reinforcement 8 of a fixed length is inserted through the auxiliary reinforcement insertion hole 23 provided in the uppermost horizontal protrusion 22. This auxiliary strip 8 has a so-called "bar" function, and is used to protect the substrate 2 of the other single-sided panel 2.

) to hold.

As described above, other single-sided panels 2 are successively erected in the height direction. Moreover, one side panel l and another single side panel 2
To connect them laterally, as shown in FIG. 2, a connecting bolt V is used to press the abutting vertical ridges 12, 12 and horizontal ridges 22, 22 together. Furthermore, single-sided panel 1.
At the protruding corner side 0 formed by 1, one of the longitudinal protrusions 12 is removed and brought into contact with the longitudinal protrusions 12 of the single-sided panel I, and fixed with a connecting bolt V. On the other hand, at the corner formed by the other single-sided panel 2.2, it is fixed by connecting bolts v, v using L-shaped fittings P.

The wall formwork of the present invention is formed by each of the above-mentioned constructions. This wall formwork has sufficient rigidity due to the vertical ridges and horizontal ridges, respectively, and the vertical strips are arranged on the single-sided panel L itself via the horizontal strips 5, 5 inserted into the vertical ridges 12 of the single-sided panel L. The stop bars 4, which are provided and fixed to the vertical bars 3, are the "bars" of the auxiliary bars 8 inserted into the horizontal protrusions 22, 22 of the other single-sided panel 2.
Because it can be attached to another single-sided panel 2 due to its function, in other words, the single-sided panel l and the other single-sided panel 2 have vertical stripes 3,
Stop muscle 4. It will be erected with a predetermined width through the horizontal reinforcements 5, 7 and the auxiliary reinforcement 8, and even if concrete is poured in the space H formed by this single-sided panel l and the other single-sided panel 2,
The lateral pressure of the concrete is sufficiently supported by each of the above-mentioned reinforcing bars. Therefore, in the wall formwork of the invention, only the formwork does not bulge.

<Effect of the invention) As mentioned above, there are one-sided panels and other single-sided panels.

The various reinforcing bars installed and arranged inside the panels sufficiently withstand the lateral pressure of concrete, and therefore there is no need to provide any shoring or the like on the outside of either single-sided panel. Therefore, a finishing material can be provided on the outside of each single-sided panel. For example, a single-sided panel used for the outer wall can be sprayed with mortar, tiled, etc., and a single-sided panel used for the inner wall can be pre-applied with an inner wall finish, such as cross-covering. Moreover, the interior and exterior finishes will not be damaged during the erection of the formwork and the pouring of concrete.

As described above, the structure of the building wall formwork of the present invention has sufficient durability as a formwork, and is also extremely effective, such as enabling the waste formwork construction method that does not require interior and exterior finishing on site. It has a rational formwork structure.
