Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a concrete wall for a building, and more particularly to a method for pouring a concrete wall in which a heat insulating plate is integrally formed on the wall surface.

BACKGROUND ART In recent years, insulating concrete walls with hard synthetic resin foam boards such as polystyrene foam and hard urethane foam board integrally laminated on the surface have come into widespread use to improve the thermal efficiency of buildings.

Conventionally, to construct such an insulating concrete wall, first, formwork for pouring concrete is placed at regular intervals, vertical butter and horizontal butter are placed on the outside of the formwork to hold down the formwork, and one side is This is done by temporarily fixing a hard synthetic resin foam board to the inner surface of the formwork with adhesive or screws, or by using the entire formwork to which the hard synthetic resin foam board has been temporarily fixed with adhesive, etc. The work efficiency was extremely low, and the surface of the hard synthetic resin foam board was damaged when the formwork and the hard synthetic resin foam board were separated, reducing the insulation effect and damaging the appearance. was there. It is an object of the present invention to provide a construction method that eliminates these drawbacks, has good work efficiency, and provides a good wall surface finish.

That is, in the present invention, a formwork is arranged at a predetermined distance from a heat insulating board made of a hard synthetic resin foam board with a reinforcing material embedded therein, and the mold is brought into contact with the butter so as to be perpendicular to the reinforcing material of the insulating board. A heat insulation method characterized by fixing both of these with fasteners, then pouring comfleet into the gap formed by the heat insulating board and the formwork, and removing the fasteners and formwork after the concrete has hardened. This is a method of pouring concrete walls into which plates are integrally formed.

A description will be given below according to the embodiments in the drawings.

Figure 2 shows the heat insulating board ((1)
It is. Moisture-proof sheets (12) and (13) are attached to the front and back sides of a hard synthetic resin foam board (2) to prevent moisture absorption. A reinforcing material (1 m (s/)) is buried along the sides. The hard synthetic resin foam board (2) is hard enough to maintain the shape of the board, and is made of Boristile/foam and hard urethane foam. Other suitable materials include phenol 7 ohm and incyanurate foam, which have excellent heat insulation properties.

Moisture-proof sheets) (12) and (13) are made of kraft paper coated with synthetic resin, synthetic resin sheets, asphalt roofing, laminated sheets of these, etc., and molded into a hard synthetic resin board (2). The moisture-proof sheet (12) (13) may not necessarily be provided, although it may be integrated with the front surface or may be integrally bonded to the front and back surfaces with an adhesive after the entire hard synthetic resin plate (2) is molded. Reinforcement material (
3)% (3') is the horizontal reinforcement (3)2 in this example.
The book and two vertical reinforcing members (3') are buried and integrated at a depth of 1 in the middle of the plate thickness, but the reinforcing material may be installed only in one direction, either vertically or horizontally, or The number can be set according to the required strength, and the buried depth is the same as the thickness of the insulation board, and it may be buried and integrated in a structure that extends from the front side of the insulation board to the back side. As the reinforcing material (3), wood, iron, aluminum, etc. can be used.

Stand such a heat insulating board (1) on one side, put the formwork on the other side (opposite the seagull, make it contact the outside of the heat insulating board (1) and formwork (5), and apply a vertical butter (5). Further, if necessary, provide a horizontal butter ('21) from the outside of the vertical butter (5), and pass it through the round separator (14)'!? insulation board (1) and formwork (8) to form the desired shape. 3-1-, and fix the tightening using a fastener (6) such as a form tie to form the interval for driving the comfleet ladle.At this time, the insulation board (1) is directly connected to the insulation board 1Jt
Place the reinforcing material (3) perpendicularly to the vertical butter (5) that is in contact with it.After this, concrete IJ - If you remove all the fasteners (6) and formwork (8), you can create a concrete IJ.
-) A heat insulating wall is obtained in which the heat insulating plate (1) is integrally attached to the surface of (4).

Heat insulating board (1)
(1) At the part where the terminals of the same kind meet, as shown in Figure 3, a waterproof flexible tongue piece (9) such as a plastic sheet is attached to the back end of the heat insulating plate (1) on one side.
Install the adjacent insulation board (1') when mating.
When stacked on the back side of the heat insulating board, the butt joint part of the end of the heat insulating board is completely shielded, so there is no risk of poured concrete (4) leaking outside from this part. Also, Figure 3 1
)K As shown, a packing (10) made of elastic rubber or soft synthetic resin foam is attached to the end of the heat insulation panel (1).
If the mounting is carried out in one piece -4-, the butt joints will be in close contact with each other due to compression with the end of the adjacent heat insulating board (1')6. By making the end portions of the heat insulating plate (1) and the heat insulating plate (1') adjacent to each other into interdigitated #) (11), the sealing performance of the joint portion is improved. As described above, the present invention embeds the reinforcing material in the hard synthetic resin foam board and arranges the heat insulating boards so that the reinforcing material is perpendicular to the supporting butter, so that the supporting butter and the reinforcing material have excellent longitudinal and lateral strength. The insulation board is reinforced so that it does not sag, and it is strong enough even without a formwork, so there is no need for the formwork to come into contact with it. This eliminates the traditional process of installing formwork and improves work efficiency.

Moreover, since only half the amount of formwork is required, construction costs are reduced. Moreover, since there is no need to peel the heat insulating board from the formwork, there is no risk of damaging the surface of the heat insulating board, there is no reduction in the heat insulating effect, and the appearance is good.

In addition, since the concrete wall constructed according to the present invention has wood or metal reinforcing material embedded in the heat insulating board, nailing and riveting can be easily performed, and the construction of wall finishing materials is different from conventional wall structures. Similarly, there are some effects that can be achieved very easily.
