Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the method of forming a heat insulating wall base, and its purpose is to form a heat insulating layer composed of three foamed synthetic resins evenly over the entire surface of the wall base without any gaps. The object of the present invention is to provide a method for forming a completely heat-insulating wall base that does not cause dew condensation due to local thermal irregularities during the cold season.

Another object of the present invention is the construction ability to instantly form an ideal heat insulating layer between the nitrogen ground and the nitrogen ground through a simple operation of spraying foamed synthetic resin onto the stretched net shrine. It is in providing the law.

Another object of the present invention is to provide a heat insulating layer of N synthetic resin between the thin strips stretched flush under tension and the nitrogen ground, so that they can be stably fixed without creating any slumps. .

To provide a method for constructing a heat insulating wall base that is advantageous for finishing work without causing any hindrance to the installation of wall boards, etc.

Heat insulating walls in which a heat insulating layer of foamed synthetic resin is interposed between a wall board and a nitrogen ground are well known and are gradually becoming popular as the demand for energy conservation increases.

By the way, if we roughly categorize conventional insulation walls from a structural perspective, they are as follows:
There are two methods in which a heat insulating board such as a foamed steel board is sandwiched between the wall board and the wall base surface, and another method in which foamed synthetic resin is injected and filled by foaming in place through holes provided throughout the wall board and connected to the wall base surface. It can be divided into methods that form a heat insulating layer between the
The former method not only takes time and effort to cut the insulation boards to the required size to suit the construction site, but also requires stocking bulky insulation boards produced at the factory and having to transport them to the construction site. There was dissatisfaction with the fact that it had to be G.

For these reasons, the latter method, which can be easily constructed by foaming on site, has been viewed as promising. However, first-order ffllt points have been found in insulation walls constructed using this method.

■ Because the foamed synthetic resin is injected in register through the holes in the wall board,
Even if there are imperfections in the formation of the Iil'i thermal layer, they may not be detected and may cause condensation.

■ There is no cutting on the part where the torso is installed! : The shell is not filled, the insulation of the rim part is incomplete, and linear condensation tends to form on the wall surface located there.

The present invention was made in view of the fact that although the latter method, which allows construction by foaming on site, is very advantageous in terms of ease and speed of construction, it still has the above-mentioned drawbacks.b
Therefore, we focused on the structure of the wall base as a key point in solving this problem.

That is, two aspects of the present invention will be described based on the illustrated embodiments: A large number of fixing devices 1 are arranged in rows on a wall base W surface so that the fixing surfaces F are all flush with each other.

On one row of these fixing tools, a rail + A2 having grooves 21 bored in the longitudinal direction on one surface is fixed.

After it is fixed, cover the entire wall base W from above the moon 2 (thin +
At the same time as A3 is spread, the net material 3 is held in the concave groove 21 on the side 2, and the press plate 4 is fitted and fixed as shown in (=1) to tension the net material 3 so that it is flush.

The space created between the net material 3 stretched in this way and the wall base W surface is filled with foamed synthetic resin through the mesh of the net material 3 to form a heat insulating layer 5. The present invention relates to a method for forming a heat insulating wall base characterized by the following.

To add further notes regarding the present invention, 1. The wall material W to which the method of the present invention is applied is mainly concrete 1. Although it is not necessarily limited to this, 2. For example, walls made of bricks, steel plates, etc. Of course, it can also be applied to wall materials.

The fixing devices l arranged in a row on the wall surface W are adjustable bolt type fixing devices as shown in FIGS. Matching fixed surface I? A fixing device consisting of a flat bolt 13 is used. This fixing device 1 is preferably made of a soft, semi-hard, or low-foaming synthetic resin material, etc., and is preferably made of a soft, semi-hard, or low-foaming synthetic resin material. In order to do this, the sleeve 12 may be fixed with nails or adhesive, or the sleeve 12 may be embedded in advance when pouring concrete into the wall base. The fixture 1 shown in FIG. 8 is suitable for fixing with adhesive, and the fixture 1 shown in FIG. 10 is suitable for being embedded in concrete.

Thus, the pole 1 is attached to the sleeve 12 fixed to the wall base W.
The screws 3 are screwed together, and the level of the fixing surface F of these holes 3 is adjusted.

After fixing on one row of fixtures arranged as above 2
1 current is produced by water conservancy. Although the concave groove 21 bored in the rear part 2 is L-shaped in the example shown in Figure 5, it may be a V-shaped groove, and in short, it is sufficient as long as it has a shape that allows the presser plate described later to be easily fitted therein. .

The net material 3 is made of Cat, cheesecloth (cotton or vinylon) of about 18 to 25 mesh.

By fitting and fixing the holding plate 4 into the groove 21 of the wedge material 2, the wedge material 2 is tensioned and fixed flush with the surface of the wedge material 2. Pressing plate 4 &;
It is usually fixed to the side 2 by nailing. In addition, net material 3
In order to tension and fix the ljd, first fix both *ljd to the wedge material 2, and then fit the presser plate into the groove 21 of the middle rear lug 2.

(For the foamed synthetic resin that is the material for layer 5.

Preferably, foamed urea resin is used. When the foamed urea resin is injected between the net material 3 and the wall material W surface, the foamed urea resin
Since no foaming pressure is applied to the foaming pressure, the surface properties of the netting material 3 are not impaired, and since the fluidity during injection is good, it quickly spreads to the space between the netting material 3 and the wall base material W, making the pouring work easier. This is because it is easy and does not generate toxic gas in the event of a fire, which is advantageous in terms of disaster prevention.

The method of the present invention is generally carried out as described above.

The invention is in no way limited to the illustrated embodiments (
, various modifications are possible within the scope of the claims. 2 For example, if the level of the fixing surface F of the fixing device L can be aligned, and the horizontal side 2 of the fixing device L can be fixed by point support, it is not necessarily the case. It does not have to be in the Pol 1-Nand format,
Moreover, the 44 qualities of the net material 3 and the foamed synthetic resin are not limited to the above-mentioned specific examples.

As explained above, the W1 thermal wall base formed by the method of the present invention is interposed between the W1 surface of the wall base and the fixture 1. A foaming compound (Al fat is injected and filled to form a heat insulating layer 5) is formed through the fine pores of the net material 3 which is tension-supported flush with the presser foot 4 through the crosspiece 2.
Because it forms the.

No gaps are created in the heat insulating layer 5.

In addition, even if a gap were to be found, it could be detected during work and corrected immediately, so it can be said that there is no condensation caused by local insulation irregularities in Ivi thermal walls that use this wall base, which is the case with conventional insulation walls. Yes, there is also the work of injecting the sealant N resin through the mesh of netting material 3.

This method is significantly simpler and more efficient than the conventional method of injecting through holes in the wall board, and the formed tlJi thermal layer is stably supported and fixed by the mesh of the mesh material 3, so the heat insulating layer No. 5 does not shrink due to dryness or other causes, and there are no gaps or cracks.

As described above, if a heat insulating wall is constructed using the method of the present invention, problems that were conventionally considered unavoidable in this type of heat insulating wall can be avoided.
It is possible to remove all points, and its practicality is extremely high.
