Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an integral construction method for balconies, external corridors, etc. in construction work, and a formwork for drainage gutters used therein.

Balconies and external corridors require complex construction work, such as installing drainage gutters and roof drains, and conventionally, after pouring concrete for the frame floor, concrete for standing walls was poured. The construction was carried out in two steps, such as pouring the roof drains, and the installation of roof drains and the formation of drainage gutters were often done separately, which was tedious and time-consuming.

In addition, conventional wooden comb formwork used as formwork for drainage ditches has drawbacks such as poor fixation, poor alignment, and easy damage to the side surfaces of the groove when demolding the formwork.

In order to prevent such drawbacks, a metal formwork as shown in Japanese Utility Model Application Publication No. 56-76845 has been devised, but this metal formwork does not take into account the connection of the formworks in the lateral direction. However, there was a risk that the installation would be time-consuming, and no consideration was given to connecting it to the roof drain.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, to streamline construction by making it possible to form drainage gutters and install roof drains all at once, and to provide an integral construction method for balconies, etc. To provide a metal formwork for a drainage gutter used in a drainage ditch, which is easy to connect with each other in the direction of passage and has a stable structure with little wobbling when assembled.

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

First, the formwork for drainage gutters of the present invention will be explained.
As shown in FIG. 1, the drain gutter formwork A has an abbreviated shape and has a cross-sectional shape that matches the shape of the drain gutter.The upper end of the back wall 1a of the metal channel member 1 is bent horizontally to form a horizontal ceiling plate 2.
A front wall 1C rising diagonally forward from the bottom plate 16 of the channel member 1 is further raised vertically upward to integrally form a front plate slot.

On the other hand, side plates 4 and 4' are provided at both left and right ends of the channel member 1 and are perpendicular to the ceiling plate 2 and the front plate 6, and the entire structure is formed into a box having an opening 5 at the upper part of the front surface.

A drain hole 6 is provided at the lower end of the side plate 4.4', and a hole 7 for a separator is provided in the back wall 1a and the bottom plate 1b.

In addition, a long hole 8 for upper mounting is formed in the ceiling plate 2, a long hole 9 for inserting a pearl is formed in the front plate 2, and furthermore, a long hole 9 for inserting a pearl is formed in the side plate 4.
A clip hole 24 is provided at 4'.

As shown in FIG. 6, the metal drain gutter form A of the present invention is installed between a floor form 10 and a front form 11 for a rising waist wall vertically erected from the floor form 10 via a separator 12. Fix it.

In the figure, numeral 1B indicates a thumbscrew that is screwed into the protruding end of the center plate 12.

As shown in Fig. 2, the side plates 4 and 4' of the formwork are brought into contact with each other and fastened using the joint clips 14, and the indoor side mold for the rising waist wall is placed on the ceiling plate 2 of the formwork A. An aluminum frame 15 serving as a frame is placed and fixed with clips 22 through elongated holes 8. Note that a plywood formwork similar to the floor formwork 10 may be used instead of the Alform 150.

On the other hand, as shown in FIG. 4, a roof drain fixing hardware 16 in the form of a metal plate having a vertical circumferential flanges 16a is nailed onto the floor formwork 10, and a roof drain 17 is fixed onto the roof drain fixing hardware 16. The bolt 19 is made to stand upright by fitting the lower end and screwing the end into the nut 18 fixed to the center of the inside of the fixed hardware 16.

The sides of the drainage basin hardware 20 of the metal box body as shown in FIG. The two are matched and fastened together with a clip 22. This drainage basin hardware 20 is placed on the upper surface of the roof drain 17, and the upper end of the bolt 19 protrudes from the bottom of the drainage basin hardware 20, and a wing nut 26 is screwed into the protrusion and tightened. In this way, the roof drain 17 can be placed between the floor formwork 10 and the drainage basin hardware 20.
The roof drain 17 can be fixed securely, and the drainage basin hardware 20 for fixing the roof drain 17 is fixed to the formwork A for the drain gutter, resulting in an overall solid formwork structure in which each part is interconnected. .

After constructing the formwork as described above, floor formwork 10 and formwork 1
If concrete IJ -1- is poured between 1.15 and 1.15, slab B will be created.
The raised waist wall C can be constructed integrally, and the installation of the roof drain and the formation of the drainage gutter can also be done at the same time. FIG. 6 shows a longitudinal cross-sectional perspective view of the balcony constructed in this manner.

Incidentally, rainwater that enters the formwork A + floating water during concrete IJ-casting can be treated by passing through the drain hole 6, while rainwater that accumulates in the drainage basin metal fittings 20 can be disposed of by passing through the drainage holes 6.
It passes through a drain hole 25 provided at the bottom of the drain hole 25, and is discharged downward through a drain hole 26 provided in the fixed hardware 16 and a drain hole 27 drilled in the floor form 10.

As described above, the integrated construction method for balconies, etc. and the formwork for drainage gutters of the present invention can form drainage gutters and install roof drains all at once, reducing the number of steps and streamlining construction. In addition, we have improved the conventional metal formwork for drainage gutters to create a sturdy formwork that is easy to connect with each other and has less wobbling when assembled. 11-. Furthermore, mortar finishing, which is to be performed later, can be omitted, reducing the number of steps and streamlining the construction process.
