Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a heat insulation construction method for imparting heat insulation performance to a building.

Conventional technology There are two main types of insulation construction methods.

The first is the installation method of glass wool, which is often used in wooden houses. The second method is spraying urethane foam, which is often used in non-wooden buildings.

The problem that the invention aims to solve What is wrong with the first conventional technology in terms of construction?

Gaps are likely to form, and problems remain with the insulation structure.

The second conventional technology involves protruding a liquid injection nozzle squarely toward the opposite side, injecting the liquid, and letting the injected liquid flow downward by the own vehicle, or attaching a flexible hose to the injection port of the injection nozzle. Injecting liquid is carried out by inserting a hose deep into the insulation space of a building, but with this method, it is difficult to inject liquid into the entire intermediate area. It is quite difficult to fill every inch with insulation material.

The present invention has been made in view of these circumstances, and includes devising an injection nozzle, devising a foaming liquid injection means, and using a well-known in-situ foaming foaming liquid as the foaming liquid. The purpose of this invention is to propose an excellent insulation method that can fill the entire middle part of a building with insulation material, whether it is a wooden building or a non-wooden building.

Means for Solving Problems In order to achieve the above object, the present invention has an injection nozzle whose injection port side part is bent at an appropriate angle, and is inserted into a space for insulation material of a building, and the injection nozzle is inserted into the center of the injection nozzle. We propose a means of rotating the foam at an appropriate angle around the line, blowing out the foaming liquid that has been foamed in situ, and injecting it while discharging the air in the space for the heat insulating material.

Function: Since the present invention comprises the above-mentioned means, the curved injection port side part of the injection nozzle is inserted toward the deep part of the insulation space of the building, and the nozzle rotates, thereby causing the foaming liquid to flow out. It spreads out due to centrifugal force, is blown deep, and is injected into every nook and corner, foaming and hardening in the order in which it is poured.

Example Injection nozzle construction required prior to insulation construction method.

The structure of the building will be explained first, followed by the construction method.

The injection nozzle (1) is shown in the third diagram, the fourth diagram, the ninth diagram,
As shown in Figure 10, move the inlet side part (101) at an appropriate angle (
The illustrated example is bent at an angle of about 45 degrees) so that when inserted into the heat insulating material space (201) constructed in the building (2), the inlet side part (101) faces the deep part.

According to experiments, the bending angle (0) of the injection port side part (101) of the injection nozzle (1) is preferably about 45 degrees, but it is not limited to this angle, and floor,
It is determined by taking into consideration the inclination angles of walls, ceilings, etc., and the inclination angles of the insulation space (201) accompanying them.

Buildings (2) are non-wooden buildings (Figures 1 to 6).
The illustrated example shows the case of a concrete building.
Figure 12 shows the case of a wooden building.

When building (2) is a non-wooden building and the floor is made into a heat insulating structure, in order to form a space for heat insulating material (201),
Partition material (4) on the indoor surface of the floor of the frame (202)
An appropriate number of partitions are arranged at predetermined intervals, and a floorboard (5) is laid on each partition material.

Then, when the foaming liquid is injected, the space for insulation material (201
) is partitioned into a bag-like shape, and air pockets are likely to be formed between the foamed and hardened insulation material and the partition material (4), for example - each corner of the floorboard (5) (the corner of each partition material) Ventilation holes (6) are drilled in the corresponding areas), and an appropriate number of injection holes (7
) are opened and arranged in the length direction, and the injection port side part (101) of the injection nozzle (1) is inserted into the injection hole, and the air accumulated in the insulation space (201) is removed through the ventilation hole ( 6) While removing it, inject the foaming liquid. Therefore, an appropriate number of injection holes (7) are opened at equal intervals, but
The injection holes (7) closest to both ends of the floorboard (5) are
Holes are drilled in areas where the spacing from both ends of the floorboard (5) is shorter than the equal spacing between the injection holes, and the foaming liquid is injected toward each corner of each partition material (4). Injection of the foaming liquid is started from the injection hole (7) at the extreme end.

In addition, in the case of a non-wooden building, when the walls are made into a heat-insulating structure, in order to form a space for heat-insulating material (201),
A level-adjustable spacer (8) is fixed to the indoor surface (hereinafter referred to as the frame wall surface) of the wall (202),
After level adjustment, the interior board (9) is attached. The spacer (8) is a short cylindrical body (801
) and a short column body (802) that fits into this short cylinder body in a manner that allows adjustment of the protrusion length. By adjusting the protrusion length of the short column body, the structure wall surface and the short column body (802 ) with the protruding end. The interior board (9) attached to the spacer (8) is attached to the space for insulation material (as in the case of the floor).
201), an air vent hole (not shown) is opened in part hE so that the foaming liquid can be injected while removing the air accumulated in the upper end of the space, for example, the upper end of the space.
In addition, an appropriate number of injection holes (10) are opened at equal intervals in a region that does not overlap with the spacer (8) and arranged in tandem, and the injection port side portion (101) of the injection nozzle (1) is inserted through the injection holes;
The foaming liquid is transferred from the lower side to the upper side of Eji while driving the air accumulated in the insulation space (201) toward the upper end and removing it from the air vent hole that can be drilled at the upper end of the interior panel (9). Make sure to inject while doing so. A suitable number of injection holes (10) are opened at equal intervals, but the injection holes (10) are located closest to both ends or one end (lower end) of the interior panel (9).
The holes are drilled at a portion where the distance from both ends or one end (lower end) of the interior board (9) is shorter than the equal distance between the injection holes, and the foaming liquid flows into the space for the insulation material. (201) so that it will be injected into every corner.

When the building (2) is a wooden building, the floor should be made into a heat insulating structure in order to form a space for heat insulating material (201). An appropriate number of partitioning materials (4) are arranged at predetermined intervals, and floorboards (5) are laid on each partitioning material. Parts where air pockets are likely to be formed between the partition material (4), for example, the floorboard (5)
) in each corner (corresponding to the corner of each partition material), and drill a ventilation hole (6) on the center line of the width side of the floorboard (5) (on the center line between each partition material (4)). An appropriate number of injection holes (7) are opened and arranged in the direction of the opening, and the air accumulated in the insulation space (201) is removed through the ventilation holes (
6) while injecting the foaming liquid from the injection hole (7). Appropriate number of injection holes (7) mutually spaced apart (evenly spaced) and space between holes fi11 (at equal intervals) from both ends of the floorboard (5)
(short interval) is the same as for non-wooden buildings, starting injection of the foaming liquid from the injection hole (7) at the extreme end.

In the case of a wooden building (2), when the walls are insulated with 44 walls, the space between the outer wall and the interior board is covered with a partition material (8) in the horizontal direction or as shown in the example, as seen in the example of large wall construction. When using the space as a heat insulating space (201), an appropriate number of ventilation holes are provided in the interior panel (9) depending on the direction of the partition. (11)
Also, pay attention to the opening site of an appropriate number of injection holes (10). When constructing a new space for insulation material (201) on the wall of a wooden building (2), install an appropriate number of partition materials (8) vertically or As shown in the illustrated example, the interior panels (
9) and open an appropriate number of injection holes (10) and an appropriate number of vent holes (11). The appropriate number of injection holes (10) are opened at different locations depending on the partitioning direction of the insulation material space (201). ), directly below the partition material, each partitioned insulation material space (201) is opened parallel to the partition material (8), and the injection holes are mutually connected. Open holes at equal intervals, and insulate the H-shaped space (if the space is partitioned horizontally by a vertical partition material (not shown), the vertical interior board (
9) On the width side center line (on the center line between each vertical partition member), vertical holes are drilled at equal intervals, but the interior board (
The injection hole (10) closest to both ends or one end (lower end) of the interior panel (9) is such that the distance from both ends or one end (lower end) of the interior panel (9) is equal to the distance between the injection holes. In both examples, the holes are drilled at locations where the distance is shorter than the gap, and in both examples, the holes are drilled at locations where the foaming liquid is injected into every corner of the insulation material space (201). When the insulation material space (201) is vertically partitioned by a horizontal partition member (8) as shown in the illustrated example, an appropriate number of ventilation holes (11) are provided in each partitioned insulation material space. (201), and if the space for insulation material (201) is horizontally partitioned by a vertical partition (not shown), the partition An opening is made at the upper end of each of the insulation material spaces (201), and in each case, so that no air pocket is formed between the foamed and hardened insulation material and each partition material (8), The foaming liquid is injected sequentially from the bottom to the top while removing the air accumulated in each heat insulating material space (201).

If the building (2) is a non-wooden building or a wooden building, the original construction method for the 61 ceiling is to adopt the conventional construction method, but if the building (2) is a box-shaped building, for example, In the case of a refrigerator, a ship's cabin, etc., it is possible to construct a structure similar to the above embodiment with a 4V insulation floor and inject a foaming liquid that can be foamed in place.

Next, the insulation construction method will be explained. Regardless of whether the building (2) is a non-wooden building or a four-wooden building, the order of construction is to move on to the walls after the floor is completed, and if the large moon is to be constructed, it will be constructed last.

First, we will discuss the floor insulation construction method.

Insert the injection port side part (101) of the injection nozzle (1) into the injection hole (7) at the end of the floor plate (5), so that the injection port faces the deepest part of the insulation material space (201). Adjust the insertion angle of the injection nozzle (1) to start injection of the foaming liquid (3). During injection of the foaming liquid, the injection port side part (101) of the injection nozzle (1) is rotated at an appropriate angle around the center line of the injection nozzle (1) so that the rotation locus draws a fan shape, and the foaming liquid ( 3) expands to the end due to centrifugal force, and the air vent hole (
6) Make sure that the air is blown out to the deepest part and injected into every nook and corner. When the injection from the injection hole (7) at the end is completed, the foaming liquid (3) is injected from the injection hole (7) at the end in the adjacent injection hole row arranged in the longitudinal direction after the foaming hardening is completed. and construction will continue. This construction order is necessary for the injected foaming liquid (3)
foams while pushing forward in the length direction of each partitioned insulation material space (201), so the construction order (injection order) is based on the injection holes (
7) (see the foaming direction and construction order not shown in parentheses in Figure 13). Injection G injected from one injection hole (7) is the injected foaming liquid (3)
The temperature is such that the foam foams inside the heat insulating material space (201), reaches the injection hole (7) used for injection, and a small amount overflows. The injection time for injecting from one injection hole (7) is
The discharge amount from the injection nozzle (1) and the space for insulation material (2)
01). The discharge pressure at the time of injection is set to such a level that the foaming liquid (3) is blown away in the horizontal direction beyond the equal distance between the injection holes (7) (for example, 455#I#I).

In this way, the foaming liquid (3) injected into the heat insulating material space (201) of the method foams and hardens to become the heat insulating material (12).

Next, we will explain the wall insulation construction method shown in the diagram.

ti If the building (2) is a non-wooden building (1st diagram to 6th diagram)
In the case shown in the figure), the injection port side part (1
01), adjust the insertion angle of the injection nozzle (1) so that the injection port faces the deepest part (lower side of the injection hole), and start injection of the foaming liquid (3). During injection of the foaming liquid (3), the injection port side part (10
1) is rotated at an appropriate angle around the center line of the injection nozzle (1) so that the rotation locus draws a fan shape, and as the foaming liquid (3) spreads outward, it touches the upper end of the interior plate (9). While expelling the air through the vent hole (not shown) that can be opened, it is blown toward the deepest part and injected into every nook and corner.

When the injection from the injection hole (10) at the lower end is completed, after the foaming has hardened, the foaming liquid (3) is injected from the injection hole (10) at the lower end of the adjacent column of injection holes to continue construction. . The reason why the application order is perpendicular to the foaming direction of the foaming liquid (3) is for the same reason as when applying to the floor (see the foaming direction and construction order not shown in parentheses in Figure 13). ). In this way, once the injection has been completed from all the injection hole stages at the lower end, the construction is carried out sequentially moving to the upper injection hole stages as shown in the figure (Fig. 3).

The illustrated example in FIG. 4 shows an example in which injection is performed from the third injection hole stage from the bottom).

If the building (2) is a wooden building (as shown in Figures 7 to 12), the lowermost space for insulation material (IF of 201)
Insert the injection nozzle (1) into the d° large hole (10) on either right end.
), insert the injection port side part (101), adjust the insertion angle of the injection nozzle (1) so that the injection port faces the deepest part (lower side of the injection hole), and start injecting the foaming liquid (3). . Foaming liquid (
During injection of step 3), press the injection nozzle (1) as shown in Figure 10.
Rotate the injection port side part (101) at an appropriate angle around the center line of the injection nozzle (1) so that the V1 locus draws a fan shape, and as the foaming liquid (3) spreads outward, the two vent holes are rotated. (11) While removing air, it is blown toward the deepest part so that it is injected into every corner.

The injection hole (
10) When the injection from 10) is completed, as shown in Figures 9 and 10, after the foaming has hardened, open the injection hole (10) at one end of the insulation material space (201) in the second stage from the bottom (used for the above injection). The foaming liquid (3) is injected from the injection hole directly above the injection hole at the bottom, while blowing it away in the same manner as described above. The reason why the foam is applied in the direction perpendicular to the foaming direction of the foaming liquid (3) is the same as when applying to the floor (see the foaming direction and construction order in parentheses in Figure 13). After injecting the foaming liquid (3) into one end of each insulation material space (201) in this way, return to the lowest insulation material space (201) again, Hole (1
Inject the foaming liquid (3) from the injection hole (10) next to 0) (the second injection hole from the left side of the RF stage in Figure 10),
Thereafter, the same order as above is repeated and construction is carried out one by one.

However, if the building (2) is a wooden building and the insulation space (201) is partitioned horizontally by a vertical partition (not shown), the wall of the non-wooden building may The insulation is carried out in the same order as in the previous example (see the direction of foaming and the order of construction not shown in parentheses in FIG. 13). In the wall insulation construction method, the injection m, injection time, discharge pressure at the time of injection, etc. from one injection hole (10) are the same as in the floor insulation construction method.

In this way, the foaming liquid (3) injected into the wall-side insulation material space (201) foams and hardens to become the insulation material (12).

Effects of the Invention In the present invention, as mentioned above, the injection port side part of the injection nozzle is bent at an appropriate angle, so it is possible to easily direct the injection port to the desired deepest part of the insulation material space during work. become. Therefore, the foaming liquid can be efficiently injected toward the desired deepest part. Then, insert the injection nozzle into the insulation material space of the building, rotate the injection nozzle at an appropriate angle around the center line of the building, and blow out the foaming liquid that has been foamed on site to spread out the injection nozzle into the insulation material space inside the insulation material space. Since it is injected while removing air, the foaming liquid is injected into the deepest corners instead of the air. Therefore, it is possible to foam and harden the foaming liquid sequentially starting from the deepest part, and it is possible to completely fill the entire space between insulation materials with insulation material, making it possible to create a building with rich insulation performance. By injecting the foaming liquid while removing the air, the injection process can be performed without any problems.
It can be carried out efficiently and the entire construction work can be speeded up.

Therefore, the stated purpose can be achieved.
