Description

[Detailed description of the invention] [Field of industrial application] The invention has excellent workability and has a heat insulation effect that is particularly useful for buildings such as thermal warehouses, grain warehouses, and silos, or for relatively low-rise buildings. The present invention relates to a composite structure of foamed mortar and permanent formwork for building structures.

[Prior art] For buildings such as thermal warehouses, grain warehouses, and silos that maintain the temperature at the required temperature and protect the stored contents without causing temperature changes, the strength of the building itself is also important. However, even more than that, heat retention is the most important element. Traditionally, these buildings were constructed using reinforced concrete, in which reinforcing bars were arranged using temporary frames, and then concrete was poured, and the concrete blocks used as the structure were carefully built one by one while arranging reinforcing bars. It was being constructed over time.

[Problems to be solved by the invention] However, in the case of reinforced concrete construction that requires the temporary frame mentioned above, a large number of highly skilled and specialized craftsmen are required, and the amount of work on site is considerable, so construction is difficult. Because it is inefficient and requires a large site area, construction work in densely populated residential areas has been extremely difficult. In addition, the masonry method using concrete blocks has superior workability and strength compared to the above-mentioned reinforced concrete construction, but since the concrete blocks are small, it takes time to construct the masonry. , construction efficiency was poor. Furthermore, concrete blocks alone cannot be expected to have a heat insulating effect, so for buildings that require heat retention, separate heat retention measures must be taken, which increases construction costs. Ta. Furthermore, in the case of low-rise buildings or the above-mentioned thermal warehouses, grain warehouses, etc., there is a demand for construction methods that are superior in heat retention rather than strength due to their functions and are highly efficient in construction.

Therefore, the present invention is based on a structural material such as lightweight foamed mortar that has excellent heat retention properties, and by combining this with the formwork unique to this invention, it has a heat insulating effect that can solve all of the problems mentioned above. The object of the present invention is to provide a composite structure of foamed mortar and permanent formwork for building structures.

[Means for solving the problems] The problems mentioned above are caused by two flat plates having a constant interval, and a horizontal reinforcing bar inserted between the two flat plates in the upper and lower center. A general notch is formed, the tips of the protrusions on both sides of the notch in the upper part protrude from the upper edge of the flat plate, and the tips of the protrusions on both sides of the notch in the lower part are the tips of the protrusions in the upper part. A formwork consisting of a partition wall located above the lower edge of the flat plate by an amount approximately equivalent to the dimension protruding from the upper edge of the flat plate, the formwork being connected in the vertical and horizontal directions, and A composite structure of foamed mortar and building structural formwork that has a heat insulating effect, characterized by having reinforcing bars arranged in the vertical and horizontal directions and filled with lightweight foamed mortar. It will be resolved accordingly.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. Reference numeral 1 in FIG. 1 is a formwork used for a composite structure according to an embodiment of the present invention, which is lighter and larger than conventional concrete blocks.
This formwork 1 has two partition walls 3,
The planar plates 2a, 2b and the partition walls 3, 3 are integrally connected so that the partition walls 3, 3 are interposed at a constant interval.

The partition walls 3, 3 are provided with notches 4a, 4b for passing the horizontal reinforcing bars in the lateral central portions of the upper and lower parts thereof, and on both sides of the notch 4a in the upper part of the partition wall 3. The tips 3a of the protrusions protrude from the upper edges of the flat plates 2a, 2b, and the tips 3b of the protrusions on both sides of the notch 4b below the partition 3 are such that the tips 3a of the protrusions in the upper part of the partition 3 protrude from the upper edges of the flat plates 2a, 2b. It is located above the lower edges of the flat plates 2a and 2b by an amount approximately equivalent to the dimension protruding from the upper edge of 2b. The reason for this configuration is that when the formwork 1 is connected in the vertical direction, the tip 3a of the convex part on the upper part of the partition wall 3 is the convex part on the lower part of the partition wall 3 of another formwork 1 located in the upper part. At the same time, the tips 3a of the protrusions on the upper part of the partition wall 3 of another formwork 1 located in the lower part enter into the protrusion tips 3b on the lower part of the partition wall 3, and later the lightweight foaming When filling and pouring mortar,
This is to obtain a stronger engagement state.

The formwork 1 described above is connected in the vertical and horizontal directions.
a, 5b are formed.

After the formwork 1 having the above structure is connected and assembled in the vertical and horizontal directions as shown in FIG. It is to be poured.

In addition, if the strength of the structure is to be increased to a certain degree, concrete may be poured in addition to the lightweight foaming mortar 6 in the formwork 1, and the flat plate 2 in the direction of the outer wall may be placed inside the formwork 1.
A decorative material 7 such as a brick may be attached to the outer circumferential surface of a in advance.

Further, in this embodiment, the number of partition walls is two, but it is not limited to this and can be changed as appropriate depending on the size of the formwork 1.

[Effects] As detailed above, the composite structure of the present invention is created by connecting lightweight formwork vertically and horizontally, arranging reinforcing bars therein, and filling and pouring lightweight foaming mortar. The formwork is integrated with the structure to be cast and does not need to be removed. In addition, the upper and lower parts of the partition wall in the formwork of the present invention are configured to interpenetrate into the vertically adjacent formworks, thereby achieving extremely strong bonding strength. Therefore, according to the present invention, unlike conventional concrete construction or masonry construction methods, which involve arranging reinforcing bars and constructing concrete blocks one by one, the temporary framework requires a large amount of work. This makes it possible to perform extremely efficient construction work without the need for skilled specialized craftsmen, and it also has excellent insulation properties that do not affect the outside temperature on stored items, making it suitable for use in thermal warehouses, It is possible to provide a composite structure suitable for use in buildings such as grain warehouses and silos.
