Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for insulating a wall of a concrete building by attaching an inorganic fiber heat insulating material and an exterior plate to the wall to create a heat insulating wall, and a heat insulating wall. This relates to the improvement of structures.

[Prior Art] Conventionally, a heat insulation construction method shown in FIG. 5 has been known as a construction method for constructing a heat insulation wall body by pasting an inorganic fiber heat insulating material and an exterior plate on the wall body of a concrete building.

That is, a heat insulating material 3 made of inorganic fiber with low thermal conductivity, such as rock wool, molded to a desired thickness is pierced and attached to an anchor bolt 2 provided in a concrete wall 1, and a washer 4 is attached to the tip of the bolt 2. is fixed to hold the heat insulating material so that it does not come off, and then a channel-shaped vertical rim 5 is applied to the surface of the heat insulating material 3, and this vertical rim 5 is fixed to the washer 4 by welding.

Thereafter, an exterior plate 6 made of an inorganic material with excellent fire resistance, such as a calcium silicate plate, is applied to the vertical rim 5 and fixed with fasteners 7 such as screws or rivets.

The wall insulation construction method described above is called the external insulation construction method, and has the advantage that construction can be performed while the person is still living in the building.

In addition, according to the structure of the insulating wall structure, in addition to the insulating material made of inorganic fibers, a space layer is formed between the inorganic fiber and the exterior board via the vertical rim, resulting in excellent heat insulating effects and dew-proofing. You can get sex. Further, there is an advantage that the longitudinal rim can be used as a support member for the exterior plate.

Problems to be Solved by the Invention] However, the above-mentioned wall insulation construction method has the following drawbacks.

(1) With the means of welding and fixing the vertical furring to the washer of the anchor bolt, the position in which the vertical furring is disposed is restricted by the position of the anchor bolt, so there is no freedom in the disposition position.

(2) Furthermore, when fixing the vertical rim by welding, a welding device is required, the process is complicated, and the workability is very poor.

[Object of the Invention] The present invention has been made in order to eliminate the above-mentioned drawbacks, and is a construction method in which insulation is carried out by pasting a heat insulating material on a concrete wall, without restricting the position of the vertical rim. The main purpose of this invention is to provide a wall insulation construction method that can be freely and easily installed, and an insulation wall structure thereof.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a horizontal body rim formed to support a heat insulating material, and a vertical body that can be assembled to freely engage with the horizontal body rim. Fix the horizontal rim to a connecting member such as an anchor bolt provided on the wall side, support the insulation material, engage the vertical rim with the horizontal rim, and assemble the vertical rim. This method aims to solve the above-mentioned problems by fixing the exterior plate to the rim.

Furthermore, the present invention fixes a horizontal rim formed to support a heat insulating material to a connecting member such as an anchor bolt provided on the wall side, and hooks a vertical rim onto the horizontal rim. A heat insulating wall structure is constructed by fixing an exterior plate to the vertical rim.

[Function] In the above-mentioned wall insulation construction method, simply by leveling the uppermost horizontal rim, it is easy to adjust the level of the other horizontal rims, which in turn makes it easy to adjust the unevenness of the wall. I can do it.

Further, since the heat insulating material is supported by the horizontal edge, it is easy to adjust the attachment position.

Furthermore, since the vertical Wi1 edge is assembled to the horizontal furring edge in a freely engaging manner, the position of the assembly is not restricted by other members.

[Embodiment Figures 1 to 4 show an embodiment of the present invention.
Components that are the same or similar to those in FIG. 5 are given the same reference numerals.

In the drawings, 1o is a horizontal rim, and 11 is a vertical rim. The horizontal furring 10 has a receiving plate portion 10 on which the heat insulating material 3 is placed and supported.
a, and a leg plate portion 1 bent downward from one end in the width direction.
0b and a standing plate part 10c bent upward from the other end, and a plurality of long holes 10d are provided in the leg plate part 10b.

The vertical furring 11 is formed of a channel portion 11a and collar plate portions 11b protruding from both sides of the channel portion 11a.
A claw piece 11c for hooking by cutting and raising is provided on the upper end side.

1 and 2 show a heat insulating wall structure constructed using the horizontal rim 10 and the vertical rim 11,
The construction procedure will be explained below.

(1) First, anchor bolts 2 are driven into predetermined locations (marked positions) on concrete wall 1.

(2) The leg plate portion 10 of the horizontal rim 10 is attached to the anchor bolt 2.
Insert the elongated hole 10d of b, and tighten by screwing the nut 12.

When attaching the horizontal rim 10, if a gap is created between it and the leg plate part 10b due to unevenness of the surface of the concrete wall, the gasket 13 is used to fill it.

(3) Next, attach other horizontal furrings one after another so that they are level with the horizontal furring 10.

(4) Next, the heat insulating material 3 is placed on the receiving plate portion 10a of the horizontal furring 10 so as to be sandwiched between the upright plate portion 10c and the wall surface.

(5) After the arrangement of the heat insulating material is completed, the vertical furring 11 is attached to the upright part 1 of the uppermost horizontal furring 10 using the claw pieces 11c.
0c for temporary fixation, and after determining the position, the lower collar plate part 11b of the claw piece 11c is fixed to the standing plate part 10c of the lower horizontal body rim 10 with screws 14.

(6) The exterior plate 6 is fixed to the channel portion 11a of the vertical rim 11 with fasteners 7 such as screws or rivets.

A heat insulating wall structure is constructed through the construction procedure described above. According to this construction method, the unevenness of the entire wall surface can be easily adjusted by simply adjusting the unevenness of the wall surface using the horizontal rims 10, and the vertical Workability is good because the level of the edges and therefore the exterior panels are automatically adjusted.

Further, unlike the conventional construction method in which the insulation material 3 is supported by being pierced by an anchor bolt, it is simply placed on the side 75 [10], so the installation work and adjustment of the installation position are extremely easy.

In addition, since the vertical furring 11 is assembled by being hooked onto the horizontal furring 10, its attachment and positioning can be facilitated.

Note that the horizontal rim used in the above construction is not limited to the shape of the above example, but may include a support part for the heat insulating material, a part fixed to the anchor bolt, and a part that engages with the vertical rim. If so, other shapes can be used. Also, regarding the vertical furring, an engaging part that can be engaged with the horizontal furring,
Any shape that allows a ventilation layer to be formed between the heat insulating material and the exterior plate can be used.

[Effects of the Invention] As described above, according to the present invention, the horizontal rim and the vertical rim are used, and after adjusting the unevenness of the wall using the horizontal rim, the vertical rim is assembled. Therefore, it can be especially applied to the external insulation method of concrete walls to simplify and speed up the work of adjusting the unevenness of the wall, installing the insulation material, and assembling the vertical frame. .
