Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a formwork apparatus for constructing beams and floors simultaneously.

[Conventional technology]

Conventionally, as a device for this food, for example,
The one published in Publication No. 9551 is known.

This formwork equipment installs a metal beam formwork on a support that can be raised and lowered, places supporting supports on the sides of the beam formwork, and straddles between the opposing support supports and the beam formwork. This involves constructing a semi-finished PC floorboard that also serves as slab formwork.

[Problem that the invention seeks to solve]

According to the above formwork apparatus, there is a problem that the metal beam formwork opens due to the weight of the semi-finished PC floorboard and the lateral pressure of the concrete. In order to deal with this, it may be possible to install a separator at the top of the beam formwork, but this poses problems such as the difficulty of accommodating the beam reinforcing bars.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention arranges beam bottom weir plates and scaffolding plates supported by shoring between column forms,
The slab formwork is constructed by spanning the slab formwork on which assembly slab reinforcements are attached to the upper surface between the opposing beam bottom weir plates via the beam side weir plate which is suspended from the bottom surface of the end with brackets. The weight of the concrete, etc. of the slab or slab is supported by brackets attached to the ends of the concrete, and the lateral pressure of the concrete is carried by the joist pipes that form part of the shoring via the beam side weir plates and brackets. Uke is held.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The figure is a sectional view of the beam/floor formwork device.

In the figure, a plurality of pipe supports 2 constituting a part of the shoring 1 are installed on the floor between column forms (not shown), and 7-ohm ties 3 are placed on these pipe supports 2.
A large pull-in pipe 4 and a joist pipe 5 are attached to each other. On the joist vibe 5, a beam bottom weir plate 6 made of plywood is fixed by the 7-ohm tie 3, and a scaffolding board 8, which will serve as a work floor when assembling the beam reinforcing bars 7, is attached to the beam bottom weir plate 6. They are placed at appropriate distances from both sides.

The joist pipe 5 is reinforced by braces 9, and handrails 11 supported by handrails 10 are provided at both ends of the joist pipe 50, respectively.

Between the opposing beam bottom weir plates 6 (only one plate is shown in the figure), a slab formwork 13 made of plywood with prefabricated slab reinforcements 12 attached to its upper surface is provided with an inverted U on the lower surface of its end. It is spanned by a letter-shaped bracket 14 via a beam-side weir plate 15 made of plywood and suspended vertically. The beam side weir plate 15 constitutes a beam form together with the beam bottom shear plate 6, and is a handrail in which a locking piece 16 provided at one lower end of the bracket 14 is tightly connected to the joist pipe 5. Hardware clamp 17
The other lower end of the bracket 14 is brought into contact with a separate glue pump 18 attached to the joist pipe 5, thereby restricting movement in two horizontal orthogonal directions.

The slab formwork 13 is reinforced by a joist pipe 19 disposed on its lower surface, and the slab reinforcements 12 attached to the upper surface of the slab formwork 13 are held by a plurality of form ties 20 with spacers (not shown) interposed therebetween. has been done.

Further, the bracket 14 is made of a steel material such as angle iron, and is removably attached to the slab formwork 15 using the form tie 20, thick pipe 21, and the like. Furthermore, the beam side weir plate 15 is attached to the bracket 1 by means of a vertical end (not shown), a horizontal end pipe 22, a form tie 23, etc.
4 is removably attached. Moreover, what is shown by a chain double-dashed line in the figure is a floor surface 24 formed by pouring concrete.

Next, in order to assemble the beam/floor formwork device having the above configuration, the shoring 1 with the beam bottom shedding plates 6, scaffolding boards 8, etc. installed in advance on the ground etc. between the column forms (not shown) is moved using a crane or the like. use [arrangement] Next, a worker stands on the scaffold board 8 and assembles the beam reinforcing bars 7 on the beam bottom weir plate 6.

After the beam reinforcing bars 7 have been assembled, the slab formwork 13 on which the slab reinforcements 12 and the beam side weir plates 15 have been assembled in advance on the ground etc. is assembled using a crane or the like on the side of the beam bottom weir plate 6 facing oppositely. Pass it between sections. And handrail hardware clamp 1
7 clamps the locking piece 16, and the bracket 1
4 by abutting the clamp 18 on the other end of the clamp 18.

〔Effect of the invention〕

As described above, according to the present invention, various effects described below can be obtained compared to the conventional technology.

(1) Since the weight of the slab formwork and slab concrete and the lateral pressure of the concrete on the beam are carried by the shoring via the brackets, the upper and lower parts of the beam formwork will not open even if a separator is not provided.

(2) Since a work floor is formed on the side of the weir plate for the bottom of the beam, there is no need to drop in the beam reinforcing bars as in the past, and the assembly of the beam reinforcing bars can be done with greater precision (and easier). .

(3) Beam formwork and floor formwork can be demolded easily and safely.

(4) The panel zone part of the column formwork is formed as a part of the beam side formwork, so the column formwork has no beam-shaped notches near the upper end, and is easy to process and erect. This makes it easy to construct the frame of the panel zone part with high precision.

Claims (1)

[Claims] A beam bottom weir plate and a scaffolding plate supported by shoring are arranged between the column formworks, and a slab formwork with assembly slab reinforcements attached to the upper surface is placed between the opposing beam bottom shear plates on the lower surface of the end thereof.
