Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wall construction method using construction equipment in an externally insulated building, which makes effective use of the appropriate energy provided to the building.

[Conventional technology]

Traditionally, internal insulation methods have been used for buildings because they are easy to install, but recently, more effective external insulation methods have been attracting attention.

Reference examples of conventional external insulation methods for buildings include the a) J et ds e% f construction method shown in Figure 7, or the anchor bolts embedded in the wall like gs hs 1% J, Or, when connecting to the framework and installing 9t of exterior materials at the next angle, 7t of heat insulating material is mainly provided.

[Problem that the invention seeks to solve]

In conventional internal insulation construction, the exterior material 9 is reliably attached to the structure.
However, when performing external insulation construction, the insulation material is incorporated between the exterior material 9 and the structure, so it is necessary to devise ways to attach the exterior material 9 and the insulation material. Unless we do something to make it cheaper, the construction cost will be higher for the parts that are insulated on the outside, so we aim to solve this problem with the present invention, which uses an external insulation method that is easy to install from an economic point of view. .

[Means for solving problems]

This invention was made in order to solve the problems of the prior art as described above, and consists of attaching a knot section 1 to the outside of a structure, installing a plate-shaped heat insulating material 7, and a reinforced resin plate 4. Attach the exterior material to the knot shape steel 1 and provide a ventilation layer using the device 10.My father attached the body rim 8 to the nut 2 with a vault and provided the exterior material 9, which caused problems with workability and external insulation. Straight pipe is the solution.

[For production]

If the action of the present invention is to be explained with reference to the drawings, Fig. 1a)
b and c are diagrams showing the structure, and by providing this external insulation construction tool on the outside of the structure, a plate-shaped insulation material 7, a ventilation layer 15,
The mounting of the exterior material 9 can be done by simply performing external insulation construction. Tighten with a vault.

The urethane foam 3 inside the hat section 1 also functions as a cold bridge prevention function and as a part where the vault bites.

Since the reinforced resin plate 4 has a lower thermal conductivity than metal,
By placing it on the concave portion of the hat shaped steel 1, a cold bridging prevention effect, a plate-shaped heat insulating material 7 and a retainer, and a gap prevention effect can be obtained.

〔Example〕

Embodiments will be described in detail below based on the drawings.

Figure 2 shows the case of a wooden building, where an inner wall board 5 is installed on the outside of the pillars, and a moisture-proof layer 6t is installed on top of it. Lay out material 7. In this case, the plate-shaped heat insulating material 70 is connected using urethane foam, or if a crosspiece is tightened using a vault on the plate-shaped heat insulating material 7 between the hat shape 1s41 and the shape steel 10, the plate-shaped heat insulating material 7 and the inner wall are connected. This will prevent gaps between the boards 5. A reinforced resin plate 4 and a flange 8 are installed on the recessed part of the hat-shaped steel 1 using a bolt 2, and an exterior material 9 is installed.

Figure 3 shows a steel frame building with 5 internal wall boards on the outside of the frame steel structure.
A moisture-proof layer 6 is provided, a hat shape steel 1 is fixed on the steel frame part with screws or a bolt, a plate-shaped heat insulating material 7 is provided, a reinforced resin board 4 and a ventilation layer 15 are provided. Tighten 10 with nuts 2 on the vault and install the exterior material 9.

Figure 4a shows the case of a block building, where the anchor bolts 12 are fastened to the block wall (in this case, the anchor bolts 12
(fixed to reinforcing bars with binding wires), provide a moisture-proof layer on the wall, make a hole in the vault shown in Figure 4, fix the knot-shaped steel 1 to the anchor bolt 12 with a nut, and attach the plate-shaped heat insulating material 7. To attach the reinforced resin plate 4 and the rim 8 or the exterior material, use the tool 10 to install the exterior material 9.

Figure 5 a is Conch! In the case of a J-TIN building, the plate-shaped heat insulating material 7, the separator hat shaped steel 1 with anchor bolts shown in Figure 5, and the reinforced resin plate 4 are installed and finished at the same time as the concrete, on the outside of the concrete formwork. (In this case) ・t shape @ 1 concave urethane foam 3
) If you reduce the front and back and use the separator 14 for construction, it will have the effect of fixing the hat shaped steel 1) To attach the exterior material, tighten the equipment with the nuts 2 and install the exterior material 9.

Figure 6 shows the case of a cloth foundation, but as with concrete buildings, external insulation construction equipment is installed, and separator 1 is installed.
4 and the vault attached to the nut 2, a 7-air truss 13 is installed on the outside of the plate-shaped heat insulating material 7 and reinforced resin plate 4, and is finished with mortar.

As mentioned above, the process of constructing the external insulation wall in the building is facilitated by using the external insulation construction equipment, but the material of the exterior material 9 1.・Since the shape steel 1, nut 2, reinforced resin plate 4, etc. will be affected depending on the size, weight, thickness of the plate-shaped insulation material 7, etc., the strength of the various exterior materials should be carefully calculated, and the dynamic wind pressure It is also safe to carry out construction that is compatible with each building and size of external insulation construction equipment tested.

〔Effect of the invention〕

By constructing a wall using the external insulation construction equipment according to the present invention, the following effects can be obtained.

■ It can be easily applied to various buildings to construct external insulation walls.

■ Since the insulation material is on the outside, it is less affected by wind and rain, outside temperature, and solar radiation.The structure's temperature changes are small and thermal behavior (expansion and contraction) is small, so the structure is protected. Figure 8a,
As shown and explained in b.

■ The structure inside the plate-shaped heat insulating material 7 is cooled by storing cold at night in the summer, and in the winter by storing heat during the day, which provides energy-saving heating effects and stabilizes the room temperature in each room.
, b. As explained in Figs. 10a and b, the following effects can be obtained: fire resistance, flatness accuracy, ease of construction, ease of maintenance, color variation, and sound performance by making the exterior material into panels.

■ By constructing an external insulation wall, the indoor space can be used widely, so the scope of use for display shelves, bookshelves, etc. is expanded, and it is also easy to install electrical, water supply, drainage, gas, etc. wiring, piping, etc., and prevent gaps due to them. is obtained. As shown and explained in Figure 11a and b, 0 ■ When internal insulation is installed, cuts are made in the insulation material and heat is released locally, which increases heat loss and makes condensation more likely to occur. Cold bridges are difficult to form with insulation. 12th
As explained in Figure aSb.

■ According to the Japan Meteorological Agency's announcement on April 5, 1989, the temperature will rise by 1.5 to 3.5 degrees Celsius in the 2030s, and the greenhouse effect caused by carbon dioxide and fluorocarbons will be strong. Being policed. As explained in FIG. 13, from these reasons, it will be necessary in the future to obtain comfort through effective use of energy through externally insulated buildings.
