Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork device for supporting concrete that has been cast during the molding of a body such as a wall, a pillar, a beam or a floor in construction and civil engineering.

[0002]

2. Description of the Related Art Generally, in construction and civil engineering, walls, pillars,
When molding a frame such as a beam or floor, for example, the form panel for wall forming and the form panel for floor forming are arranged at predetermined positions.A scaffold is assembled for assembling and disassembling these form panels. , The support pillars are erected upright, and each formwork panel is tightened with tightening metal fittings and supported by the vertical and horizontal edges.

[0003]

However, providing the form panel, the scaffold, and the support pillars independently as described above increases the number of parts, and each form panel, the scaffold, and the pillars are independent of each other. Transferring, assembling, and disassembling is difficult in workability and economical.

Also, the use of thick ends to support the form panel and to carry the load from the concrete results in a large number of parts, which complicates assembly and dismantling work.
Inferior in workability and economy.

Further, when the molding area of the skeleton is large, the form frame panels are continuously arranged in the horizontal and vertical directions. In this case, the joint between two adjacent form frame panels is not horizontal and is slightly misaligned. Differences may occur.

Therefore, an object of the present invention is to provide a formwork apparatus which can be assembled and disassembled at the same time with a formwork panel and a scaffold, and which does not require a thick material for supporting the formwork panel and is excellent in workability and economy. It is to be.

[0007]

In order to achieve the above object, the structure of the present invention comprises a formwork panel made of steel plate, and a scaffolding frame connected to the back of the formwork panel through a supporting brace.
It is characterized by comprising a scaffold provided on the upper part of the scaffold frame.

It is preferable that the form panel is formed in a box shape and a heat insulating material such as polyurethane is incorporated therein.

The form panel is provided with nuts and bolts on the right and left back portions.

[0010]

Since the formwork panel and the scaffolding frame are connected, they can be transferred together by a crane or the like, and they can be assembled or removed at a predetermined place at the same time.

The scaffolding frame holds the formwork panels upright, and concrete can be placed on the scaffolding on the scaffolding frame, assembling of the formwork on the ceiling side, dismantling, and other necessary construction and civil engineering works.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

The formwork apparatus of the present invention is briefly described in FIGS.

As shown in FIG. 2, this is composed of formwork panels 1 and 1 and scaffolding frames 2 and 2 connected to the backs of the formwork panels 1 and 1, and the formwork panels 1 and 1 and the scaffolding frame. 2 and 2 are hung by a crane or the like and transferred to a predetermined position.

At this time, the formwork panels 1 and 1 and the scaffolding frames 2 and 2 on both sides are brought close to each other by a scissors provided on the upper side by an amount corresponding to the thickness of the skeleton 4.

Next, the tightening member 5 is attached, concrete is placed using the upper scaffold 6, and the skeleton 4 such as a pillar or a wall is placed.
To mold.

Next, as shown in FIG. 3, the tightening member 5 is removed, the form panels 1, 1 and the scaffolding frames 2, 2 are moved in directions away from each other via the scissors 3, and the whole is further moved by a crane or the like. As shown by the arrow A, it is lifted up so that the skeleton 4 is left as it is.

FIG. 1 shows one embodiment of the formwork apparatus B of the present invention.

The formwork apparatus B comprises rectangular formwork panels 1, 1, scaffolding frames 2, 2 connected to the backs of the formwork panels 1, 1, and scaffolds 6, 6 provided above the scaffolding frames 2, 2. It is composed of.

The formwork panel 1 is formed of a steel plate and is formed into a rectangular box shape having a hollow interior, and a cross-section material made of polyurethane or the like is injected into the interior.

However, the form panel 1 may be formed of a single metallic flat plate.

Although only one form panel 1 can be used, the form panels 1 can be continuously provided in the vertical and horizontal directions depending on the molding area of the frame.

In the embodiment of FIG. 1, a nut 7 is provided at the left end of the back side of the form panel 1, and a bolt 8 is provided at the right end of the back side of the form panel 1 when the form panels 1 are arranged side by side. The adjacent bolts 8 and nuts 7 are connected and horizontally arranged without causing any misalignment.

The scaffolding frame 2 is composed of frame bodies 9 and 10 standing upright on the ground, and a scaffolding 6 comprising a scaffolding plate 11 and handrails 12 is provided on the upper portion of the frame body 9.

On the scaffold 6, ladders are arranged continuously downwards,
Concrete pouring work is performed on the scaffolding plate 6, and if necessary, peripheral works such as upper ceiling, floor formwork assembly, dismantling, and other work are also performed.

The frame body 9 and the scaffold 6 of the scaffolding frame 2 are connected to the mounting metal fittings 15 provided on the back surface of the formwork panel 1 via braces 13 and 14 which are horizontal and diagonal support members, whereby the formwork panel is formed. The scaffolding frame 1 and the scaffolding frame 2 are integrally connected, and are simultaneously assembled, removed, and transferred.

A hook metal fitting 16 such as a flange is provided on the back surface of the formwork panel 1 and can be connected to another support pillar through a hook and a hook metal.

FIG. 4 shows a state in which bolts 8 and nuts 7 are provided on the left, right, top and bottom of the form panel 1, and the form panels 1 that are connected in the up, down, left and right are connected in series.

The bolt 8 and the nut 7 are shown in FIGS.

The nut 7 is an end frame 1 of the formwork panel 1.
It is provided with a cylindrical portion 17 fixed to a, a socket 18 rotatably fitted in the cylindrical portion 17, and a female screw 19 formed in the socket 18.

A tapered conical inner peripheral surface 20 is formed on the cylindrical portion 17, and the socket 18 is formed in the inner peripheral surface 20.
A conical outer peripheral surface 21 formed on the outer periphery of is fitted.

A flange portion 23 having a locking hole 22 formed in a cross direction and a supporting rod 24 are provided in a protruding manner on the back of the socket 18, and a tool 25 such as Shino is supported in the locking hole 22 while being supported by the supporting rod 24. The socket 18 is adapted to be rotated by inserting it.

The bolt 8 comprises a cylindrical portion 23 fixed to the frame 1a and a screw rod 29.

A conical tapered surface 2 is formed on the inner circumference of the cylindrical portion 23.
