Description

TECHNICAL FIELD The present invention relates to a panel material arranging method for arranging a panel material on a floor or a wall inside a building.

<< Prior Art >> In a reinforced concrete or reinforced reinforced concrete building 3 in which columns 1 and beams 2 are constructed in a three-dimensional lattice shape as shown in FIG. 8, a grid space 4 corresponding to the floor or wall of the building 3 is provided. A construction method may be adopted in which the panel material 5 is fitted and arranged to form a floor surface or a wall surface.

This construction method has the advantage that the construction period is relatively short, but as shown in FIG. 8, when attempting to arrange the panel material 5 in the lattice space 4a inside the building 3, first the panel material 5 is placed outside. It must pass through the lattice space 4b and be carried into the internal lattice space 4a. However, even if the panel member 5 is hung horizontally by the crane hook 6 and lowered to the lattice space 4b, the edge of the panel member 5 interferes with the beam 2 and the panel member 5 cannot pass through. However, if the panel material 5 is hung vertically, it cannot pass through the lattice space 4b, but extremely difficult work such as tilting the panel material 5 horizontally again inside the building is required. Therefore, it is virtually impossible to dispose the large-sized panel material 5 in the lattice space 4a inside the building 3 in units of lattices. Therefore, the columns 1 and the beams 2 are constructed one by one, and each of the outsides is constructed. Panel material 5 in the lattice space 4b
Only the construction method of arranging was adopted.

In this construction method, the columns 1 and the beams 2 can be constructed only one layer at a time, so there is a problem in terms of construction efficiency.

Therefore, as a construction method to eliminate such inconvenience,
The one shown in the figure has been proposed. In this construction method, a cross-shaped child beam 7 is arranged in the internal lattice space 4a to divide the lattice space 4a into four, and the small panel material 8 is arranged in the divided small lattice space 4c. Is. In this construction method, the small panel material 8 is made to pass through the outer lattice space 4b and the inner lattice space 4a.
Since the pillars 1 and the beams 2 can be preliminarily constructed as a whole, the construction efficiency can be improved in this respect.

<< Problems to be Solved by the Invention >> The construction method of the improved panel material is configured as described above, but the following problems are newly pointed out in this construction method. That is, in the above construction method, a step of disposing the sub-beams 7 is newly added, and since the small panel material 8 is used, the number of panel materials is quadrupled all at once. Since it has to be lifted up by the crane hook 6 and carried in to a predetermined position, it is extremely inconvenient in terms of construction efficiency due to an increase in man-hours, especially in a super high-rise building.

The present invention has been made to solve the above-mentioned problems all at once, and an object thereof is to provide a panel material that can be arranged in a lattice space inside a building without increasing man-hours. It is to provide an arranging method.

<< Means for Solving Problems >> In order to solve the problems described above, the present invention provides a floor or wall by disposing a panel material in a lattice space of a building in which columns and beams are constructed in a three-dimensional lattice shape. In the method of arranging the panel material constituting the part, the panel material is divided into two or more panel pieces, and the divided parts are connected by hinge means so that the panel material can be folded. After being carried in to the lattice space inside the building in a folded state, the panel material is spread and arranged in the lattice space.

<< Operation >> In the panel material arranging method configured as described above, folding the panel material allows the panel material to pass through the lattice space of the building. The panel material can be carried in, which allows the panel material to be easily placed even inside the building where the columns and beams are entirely pre-constructed, and the folded panel material can be placed in the desired lattice space. A large panel can be obtained by re-expanding, and one unit of the floor or wall can be quickly constructed by one panel material.

<< Example >> One example of the present invention is described below based on a drawing. FIG. 1 is a side view of the panel material 12 used in the present invention. In this embodiment, the panel material 12 is a precast concrete (PC) plate formwork, but the panel material 12 is
The present invention can be applied to the PC board itself.

The panel material 12 is divided into three substantially equal-sized panel pieces 12a, 12b, 12c, and these three panel pieces 12a to 12c are mutually connected by a hinge 13 as a hinge means arranged on the upper surface of the division part. It is connected. The panel pieces 12a and 12c on both sides are configured to be foldable in the direction shown by the arrow in FIG. As shown in FIG. 4, three hinges 13 are provided for each divided portion.

On the other hand, a hanging beam 15 is horizontally hung on a crane hook 14 for hoisting and transporting the panel material 12, as shown in FIG. Five sheaves 16 to 20 are attached to the lower surface of the suspension beam 15 along the longitudinal direction thereof.
A pair of brackets 21 and 22 are provided at both ends of.
Then, both ends of the wire 23 are fixed to the pair of brackets 21 and 22, and the middle portion of the wire 23 is fixed to each sheave 16
It is routed so as to pass above 20.

Between brackets 21,22 and sheaves 16,20, and sheaves 16
Suspending sheaves 24 to 29 are attached to the wires 23 between ~ 20. A hook 30 is connected to each of the shaft ends of these hanging sheaves 24 to 29.
12 It is designed to be hooked on the reinforcing bar 31 on the upper surface.

The panel material 12 and the suspension beam 15 are configured as described above. When the panel material 12 in a horizontally expanded state is lifted by the suspension beam 15 as shown by the chain line in FIG. 2, it is shown in FIG. The hook 32a of the chain block 32 is hooked on the end reinforcing bars 31 of the panel pieces 12a, 12c on both sides, and the upper end of the hanging chain 32b of the chain block 32 is attached to the bracket 2 of the hanging beam 15.
Snap to 1,22. And in this state the chain block 32
Is operated to raise the panel pieces 12a and 12c to the angle shown by the solid line in FIG. The chain block 32 may be of an electric type, and in the case of this electric type, remote control such as radio control operation is possible.

After raising the panel pieces 12a and 12c, a crane (not shown) is operated to lift the panel material 12, and the panel material 12 is carried into the lattice space 4a inside the building 3 as shown in FIG.
At this time, since the panel material 12 is folded in a substantially U-shape, it can easily pass through the outer lattice space 4b, and there is no concern that the panel material 12 and the pillar 1 or the beam 2 interfere with each other.

After the panel material 12 is carried into the lattice space 4a, the chain block 32 is operated again to horizontally spread the panel pieces 12a and 12c. FIG. 4 shows the state at this time, but the suspension beam 15 and the like are omitted. Horizontally spread panel material
The beam 12 of the building 3 has its four sides supported on its four sides to form a floor.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and various modifications can be made. For example, although the panel material 12 is divided into three in the above embodiment,
It may be divided into two or four or more. Although a large number of sheaves are used in the above embodiment, two sheaves 36, 37 are provided on the lower surfaces of both ends of the hanging beam 15 as shown in FIGS. 5 and 6.
Attach only the ends of the wires 38, 39 wound around the two sheaves 36, 37 to the reinforcing bars 31 at the ends of the panel pieces 12a, 12c and both ends of the panel piece 12b by hooks or the like. You may wear it. In this case, the panel pieces 12a and 12c can be raised as shown in FIG. 5 simply by pulling up the suspension beam 15, and after the panel material 12 is lowered onto the beam 2 as shown in FIG.
By lowering 15, the panel pieces 12a and 12c can be automatically spread horizontally, which is very efficient.

Further, in the above embodiment, the panel material 12 constituting the floor portion has been described, but the present invention can be applied to the panel material constituting the wall portion. In this case, for example, the panel material 40 is divided into two as shown in FIG. Then, the panel pieces 40a and 40b may be connected to each other by the three hinges 13, and the panel pieces 40a and 40b may be supported by the suspension beam 41 so that they can be folded or expanded laterally.

Further, although the hinge 13 is used as the hinge means in the above embodiment, it goes without saying that a flexible member may be used instead of the hinge 13.

As shown in FIGS. 2 to 5, when the panel pieces 12a, 12c are raised, the wires 23, 38, 39 are stretched inside the panel pieces 12a, 12c. 12
There is no risk that c will unexpectedly rotate inward and fall. In order to more surely prevent the panel pieces 12a and 12c from collapsing, it is preferable to adopt a hinge 13 that does not bend beyond the angle shown in FIGS.

<< Effects of the Invention >> As described above, according to the present invention, the panel material is configured to be foldable or expandable. Therefore, even after the columns and beams of the building are preliminarily constructed in advance, the panel material is folded. It can be easily loaded into any lattice space inside, which can shorten the construction period or construction cost by constructing so-called pillar / beam tips. Further, in the present invention, since the floor or wall is constructed in the unit lattice space by one panel material,
The number of man-hours required for loading and arranging the panel material is small, and in combination with the shortening of the construction period by the construction of the pillars and beams, the construction period of this kind of building can be greatly shortened.
