Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork structure for placing concrete in construction or civil engineering work.

[0002]

2. Description of the Related Art Conventionally, molds used in construction work are supported by a large number of supporting materials for formwork plates made of wood or steel plates from both inside and outside.・ Because the removal was repeated, there were the following problems. It took a lot of time to assemble and remove the formwork, and the workability was very poor. Since a support pillar for supporting the upper load is required, the work space is narrowed and the construction site is complicated. In the case of a high-rise building, due to the problem of concrete strength, the height of concrete placement per operation was limited, and the construction period was long. In the case of using a wooden form board, a high level of technology was required for its processing, and mass production at the factory was difficult. It was uneconomical because the reuse efficiency was low because the use loss per use of the mold was large. After pouring the concrete, it was not possible to directly monitor the surface condition of the concrete in the formwork and the hardening process thereof, and even if the finished concrete became poor, this could not be prevented.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such problems, that is, the assembling and dismounting of the formwork is very easy, and the workability can be improved and the construction period can be greatly shortened. In addition, it is easy to mass-produce formwork factories in factories, and it has high reuse efficiency and excellent economic efficiency. Furthermore, after placing concrete, the surface condition of concrete in the formwork and the process of its hardening can be directly measured. It is to provide a formwork structure that can also be monitored.

[0004]

A formwork structure according to the present invention is a formwork in which a net-shaped outer panel having a support member provided at the peripheral edge of a net made of a rod or wire is framed in a box shape and arranged inside thereof. A concrete placing space is formed by holding the plate with a net-shaped outer panel.

If a net-shaped outer panel is continuously constructed on a portion which becomes a pillar of a building and a portion which becomes a beam, and a form plate is placed inside the panel, the portion becomes a pillar and a beam of the building. It is possible to place concrete at the same time on the part and construct the pillar and beam at the same time.

By making the form plate transparent, it is possible to directly monitor the inside of the form from the outside. Further, in order to reinforce the net, it is preferable to provide a reinforcing material between the support materials on both edges of the net-shaped outer panel.

[0007]

According to the formwork structure of the present invention, the net-shaped outer shell panel itself, which is framed in a box shape, forms the outer shell of, for example, a pillar portion or a beam portion of the structure to stand on its own, and the formwork plate has a net-like shape. Since it is attached to the inside of the outer panel to be held by this alone, no other supporting material for supporting the form plate is required. When pouring concrete, the form board is reinforced from the outside by the net-shaped outer panel, so the height and range of concrete pouring per operation can be sufficiently secured, and the form board itself is It is not necessary to have a thickness and strength that can withstand concrete pressure, and thin and weak ones can also be used. Constructing a net-shaped outer panel in a box shape,
It is easy to connect two or more of them in a two-dimensional and three-dimensional manner because there is a supporting member at the edge, and if the frame state is dismantled, the form plate can be removed at the same time. The workability of assembling and dismounting is extremely good. Since the net-shaped outer panel does not directly contact the concrete,
Since the structure can be used repeatedly and is suitable for mass production in factories, even if a mold plate with low reuse efficiency is used, the entire formwork is highly economical.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the formwork structure of this example uses a large number of net-shaped outer panels 1, which are
The structure 2 is constructed so as to be continuous with the portion 2 that becomes the pillar of the building and the portion 3 that becomes the beam, and also that each portion becomes a box shape, and the form plate 4 is enclosed inside the box leaving the upper surface. Are arranged (see FIGS. 3 and 4), and as a whole, it is like a temporary frame having cavities (concrete pouring spaces) 5 and 6 in each part. The concrete pouring space 5 of the portion 2 that becomes the pillar and the concrete pouring space 6 of the portion 3 that becomes the beam
4 and 5 so that concrete can be continuously poured.
As shown in. Although not shown in the drawing, a predetermined gap is maintained between the net-shaped outer panels 1 facing each other by a conventionally known separator.

As shown in FIG. 6, each net-shaped outer panel 1 is made of steel (L-shaped in the figure) at the outer edge of a net 9 in which rods or wires 7 and 8 such as reinforcing bars are assembled in a vertical and horizontal lattice pattern. Steel material)
6 and the like, but not shown in FIG. 6, a plurality of reinforcing materials 11 are provided on both sides of the supporting material 10 as shown in FIGS. 1, 2 and 3. The outer surface of the net 9 is reinforced by diagonally adhering the space between the molds 10.
It has a rigid structure with higher strength. The net-shaped outer panel 1 can be manufactured in a factory separately from the form plate 4.

Since the form frame plate 4 is held by the net-shaped outer shell panel 1 and is reinforced from the outside, the form frame plate itself does not need to have the conventional strength required for concrete pressure. Therefore, the mold plate 4 used in the present invention can be used sufficiently even if it is a relatively thin one made of an easily processable material such as paper, plastic, Styrofoam, or glass wool. Further, by making a transparent material, for example, transparent or translucent reinforced plastic, acrylic, vinyl chloride, or the like, the concrete inside the mold can be directly monitored from the outside.

Although the above-mentioned embodiment is for construction work, it goes without saying that the present invention can also be applied to civil works.

The effects of the present invention are listed below. The net-shaped shell panel itself, which is framed in a box shape, forms the shell of a structure, for example, a pillar or a beam, and is self-supporting. The form plate is attached to the inside of the net-shaped shell panel and held only by this. Therefore, since other supporting materials for supporting the form frame plate are not required, the assembling and dismounting of the form frame is very easy, and the workability can be improved and the construction period can be greatly shortened. When pouring concrete, the formwork plate is reinforced from the outside by the net-shaped outer panel, so the height and range of concrete pouring per operation can be sufficiently secured, and the higher the layer, the shorter the construction period. The effect of can be exhibited. The form plate does not need to have a thickness and strength that can withstand concrete pressure by itself, and thin and weak ones can be used, so it cannot be used as a form plate in the past. It can be used with different materials, which increases the flexibility of selection and is economical. It is easy to frame the net-shaped outer panel in a box shape, and to connect the plurality of them in a planar and three-dimensional manner because there is a support material at the edge. Since the frame plate can be removed at the same time,
The workability of assembling and removing the formwork is extremely good. Since the net-shaped outer panel does not come into direct contact with concrete, it can be used repeatedly and has a structure suitable for mass production in factories. Is highly economical.

According to a second aspect of the present invention, if a net-shaped outer panel is continuously constructed between a portion that becomes a pillar of a building and a portion that becomes a beam of the building, and a form plate is arranged inside the panel, a pillar of the building can be obtained. It is possible to place concrete and pillars and beams at the same time for the parts that will become the beams and the parts that will become the beams.

When the form plate is made transparent as in claim 3, the inside of the form can be directly monitored from the outside, so that it is possible to prevent the formation of poor concrete.

If a reinforcing material is provided between the support members on both edges of the net-shaped outer panel, the net can be reinforced and the strength can be increased.
