Description

[Detailed description of the invention] The present invention includes a flat plate formwork material, an L-shaped formwork material, a Z-shaped formwork material, and an angle-shaped formwork material, and is suitable for forming bulges of cloth foundations, etc. This invention relates to a set of formwork materials for concrete that can be formed.

Dry construction methods are often used in buildings where panels are used to form walls and floors. For example, in such a building, a bulge portion for erecting an independent column or the like may be formed on a narrow cloth foundation that supports a wall panel. Conventionally, cloth foundations with such bulges had to be assembled from wooden sheathing boards or formwork materials each time, which required time and effort to assemble the forms, and the shapes were uneven, making it difficult to obtain foundations of stable quality. It was difficult to draw.

The purpose of this invention is to provide a set of formwork materials for concrete that enables formation of a foundation with easy molding and stable quality by assembling formwork materials of a predetermined shape so that they can be connected to each other in advance. year,
One embodiment will be described below with reference to the drawings.

In Fig. 1, a formwork material set 1 for concrete according to the present invention includes a flat plate formwork material 2, an L-shaped formwork material 3,
, a Z-shaped frame material 4, and an angle-shaped formwork material 5, and the formwork material set 1 includes a lower formwork 30.
mounted on top. Each of the formwork members 2 to 5 is provided with flanges 7, 7 on the upper and lower sides of a face member 6 made of a steel plate, respectively.

The flat plate formwork 2 has side plates 9 at right angles to the rectangular flat plate 6 at both ends thereof, and a crosspiece 11 is provided adjacent to one of the side plates 9.

Further, the L-shaped frame member 3 has a face member 6 in which a rectangular flat base 12 is formed with a slightly short bent portion 13 at right angles to the outside. A right-angled side plate 14 is provided, and the edge of the bent portion 13 is open, and a strip-shaped reinforcing plate 14a is attached to the edge. Note that there is a crosspiece 11 near the side plate 14.
is installed vertically.

The Z-shaped frame material 4 has a rectangular flat base 15, a bent part 16 perpendicular to the base 15, and a protruding part 17 parallel to the base 15 protruding outward at the tip thereof. The outer width of the bent portion 16 is set to be the same as that of the bent portion 13 of the L-shaped frame material 3, and the side edges of the base portion 15 and the protruding portion 17 are provided with holes perpendicular to the face material 6. Side plates 19, 19 are provided.

The angular formwork material 5 has a base 21 in the form of a rectangular flat plate.
It has a face material 6 which forms bent portions 22 perpendicular to the base portion 21 to have substantially equal lengths. Further, a right-angled side plate 23 is provided on the side edge of the bent portion 22, a reinforcing plate 23a is attached to the side edge of the base 21, and a pair of fixing pieces 26, 26 are attached to the lower end of the base 21. is provided to protrude horizontally and at right angles to the base 21. The fixing piece 26 has a narrow and long piece shape, and the lower surface is the flange 7.
The leg piece 27 has an L-shaped cross section with a raised piece 28 provided on the side edge of the leg piece 27, which has approximately the same height as the leg piece 27.

Also, each side plate 9, 14, 19, 23 and reinforcing plate 1
4a, 23a are provided with through holes 10 that can be aligned and have the same diameter, and each frame member 2, 3, 4,
5 have the same height.

Further, the lower formwork 30 is constructed by using an appropriate formwork material and connecting the parallel parts 32 that separate the gap C.
A rectangular tube portion 33 forming a relatively large rectangular hole H communicating with the gap G is connected at one end at the same height.

The flat plate formwork materials 2, 2 are installed parallel to the parallel part 32 of the lower formwork 30, and in this example, the side plate 9 is located near the edge of the parallel part 32 facing the square hole H, and is opposed to it. At the same time, the side plate 9 of one of the flat plate frame members 2 is connected to the side plate 14 of the L-shaped frame member 3. Therefore, the base 12 of the L-shaped frame member 3 is in a straight line with the flat plate frame member 2, and the form member 3 extends into the square hole H of the lower formwork 30.

In addition, the other flat plate formwork material 2 has Z on its side plate 9.
The side plates 19 of the base 15 of the character-shaped frame material 4 are connected, so that the base 15 is continuous with the flat plate frame material 2 in a straight line and protrudes into the square hole H. Also, the reinforcing plate 1 at the edge of the bent portion 13 of the L-shaped frame material 3 assembled in this way
4a and the side plate 1 at the edge of the protrusion 17 of the Z-shaped frame material 5
By connecting the side plate 23 and reinforcing plate 23a of the angle-shaped formwork material 5 to the square hole H
A prismatic cylindrical portion is formed on the top by the bent portions 13 and 16, the protruding portion 17, and the angular formwork material 5.
Further, the fixing pieces 26, 26 are placed on the upper surface of the lower formwork 30.

The formwork materials 2 to 5 are connected using so-called U clips 31 passing through the through holes 10. As a result, a cloth foundation is formed between the flat plate frame material 2, the base 12 of the L-shaped frame material 3, and the base 15 of the Z-shaped frame material 4. In addition, each of the outwardly bent portions 13 and 16 of the L-shaped frame material 3 and the Z-shaped frame material 4 has one surface perpendicular to the fabric foundation at an angle with the protrusion 17 of the Z-shaped frame material 4. The bent portion 22 of the angled formwork material 5 has two surfaces perpendicular to the one surface and the base 21 of the angular formwork material 5.
forms the other surface perpendicular to the cloth foundation, and thus the four surfaces form a cylindrical portion on the square hole H.

However, by pouring concrete into such a formwork, it is possible to form a bulge A in the form of an independent foundation, which has a footing and is connected to a cloth foundation at one end.

As mentioned above, the concrete formwork material set of the present invention includes a flat plate formwork material, an L-shaped formwork material, a Z-shaped formwork material, and an angle-shaped formwork material. The materials can be installed opposite each other to form a continuous fabric foundation.

Further, the base of the L-shaped frame member faces the base of the Z-shaped frame member and is connected to the flat plate form member to form a cloth foundation connected to the cloth foundation. In addition, each of the outwardly facing bent parts 13 and 16 of the L-shaped frame material 3 and the Z-shaped frame material 4 has one surface perpendicular to the fabric foundation at an angle with the protrusion 17 of the Z-shaped frame material 4. The bent portion 22 of the angled formwork material 5 forms two surfaces perpendicular to the one surface, and the base 21 of the angular formwork material 5 forms the other surface perpendicular to the fabric foundation, thus The four surfaces allow a four-sided columnar bulge to be formed at the end of the cloth foundation. Furthermore, by means of the leg pieces of the angular formwork material,
To enable stable installation of formwork material sets. Furthermore, by producing such a set in advance in a factory or the like, the quality is stable and a cloth foundation having a bulge can be formed.
