Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure for forming a wall of a building by assembling panel-like wall members.
In particular, the present invention relates to a slip-off prevention structure suitable for preventing a soft material filled in a wall interior space from slipping down for heat insulation and soundproofing, and a metal fitting therefor.

[0002]

2. Description of the Related Art In recent years, instead of a conventional earth wall as an outer wall of a building, an outer wall panel such as a lightweight concrete panel, a ceramic panel, and an inner wall panel such as a gypsum board have been used for heat insulation, soundproofing, and the like. The outer wall of the structure filled with the soft material is widely used. As a flexible material used in such an outer wall structure, for example, there is a material in which an inorganic fibrous material such as glass wool or rock wool is formed in a mat shape, or a material in which the material is wrapped in a bag made of paper or vinyl chloride. .

[0003] Usually, such a flexible material (eg, grall wool) is attached to (or before attachment to) the outer wall panel at a waist edge arranged at a predetermined interval for attaching the outer wall panel and the inner wall panel. Prior to installation, the wall interior space formed between the waist edges is filled.

[0004]

In such a conventional method for constructing a flexible material, as shown in FIG. 12A, at the beginning of the construction, the space inside the wall between the outer wall panel 100 and the inner wall panel 101 is filled. Flexible material 10 such as glass wool
2 forms a heat insulating layer and a soundproofing layer and exhibits a predetermined heat insulating and soundproofing effect. However, if the glass wool 102 absorbs moisture and becomes heavy after the enforcement, it tends to slip down inside the outer wall as shown in FIG. In this case, although it is not possible to observe from the outside, a space 103 lacking the flexible material is formed above the outer wall, and a case where a predetermined heat insulation and soundproof effect cannot be obtained may be considered.

[0005] In order to prevent this, there is a method of fixing the flexible material 102 to the body edge or the outer wall panel using a double-sided tape, an adhesive, a stapler, or the like. The weight of the sucked flexible material may not be able to be supported, and the construction is troublesome. Even with the stapler, there are certain limitations, as well as the complexity and restrictions on construction (the stapler cannot be generally driven into the outer wall panel).

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple and inexpensive method for easily and inexpensively sliding down a flexible material filled in a wall interior space for heat insulation and soundproofing in a building wall structure formed by assembling panel-like wall members. It is to prevent.

[0007]

Means, actions and effects for solving the problem.
The sliding structure of the flexible material for filling the interior space of the building walls (hereinafter simply referred to as the sliding prevention structure) is a flexible material for heat insulation, soundproofing, and other purposes in the filling space between the outer wall panel and the inner wall panel. In the building to be filled, the outer wall panel supports the metal fitting for preventing the soft material from falling off. The bracket is
It has a fixing portion to the outer wall panel, and a protrusion protruding in a needle shape so as to enter inwardly from the outer wall panel and to enter the filling space. When the material is pushed in, the protrusions pierce the flexible material, and the inner wall panel is attached so as to cover the flexible material.

According to such a structure, even if the filler such as glass wool becomes heavy due to absorption of moisture after construction, the protrusions of the slip-prevention metal fittings pierced into the flexible material not only have the surface but also the thickness of the flexible material. Since it is supported up to the inside in the direction, it is possible to effectively prevent the flexible material from sliding down in the space inside the wall. In addition, the operation of supporting the flexible material is simpler and faster than the application of an adhesive or the application of a double-sided tape, since the flexible material is simply pressed and pierced against the protrusion of the metal fitting.

According to a second aspect of the present invention, the plurality of outer wall panels are connected so that their ends abut against each other, and the abutting portion supports a metal fitting for preventing the soft material from falling off. It is characterized by. In this case, the fixing portion of the sliding prevention metal fitting is supported in a state of being sandwiched between the butting portions of the plurality of outer wall panels. According to such a structure, the slip-prevention metal fitting can be fixed to the outer wall panel by fitting the slip-prevention metal fitting into the butt portion of the outer wall panel during the connection work of the outer wall panel.

A third aspect of the present invention is a more specific embodiment of the slip-off preventing structure according to the first or second aspect of the present invention, wherein a plurality of outer wall panels are provided at a predetermined interval in a plurality of body edges in a vertical direction. The present invention relates to a wall structure which is sequentially connected so as to abut each other in a horizontal direction. In this case, the abutting portion of the outer wall panel between the waist edges is provided with one
Alternatively, two or more sliding prevention metal fittings are supported, and the flexible material is pushed between the body edges against the projections of the sliding prevention metal fitting supported by the outer wall panel, so that the projections pierce the flexible material. The inner wall panel is attached so as to cover the filler.

A fourth aspect of the present invention is a structure in which the slip-off preventing structure of the second or third aspect is further embodied. Of the butted portion of the outer wall panel, a groove-shaped recess along one edge is
A protruding portion is formed along the other edge, and the concavities and convexities are abutted so as to correspond to each other. In this case, the fixing portion of the sliding prevention metal fitting has a shape corresponding to the butted portion of the unevenness, and is sandwiched between the butted portions of the outer wall panels. As a result, the fixing portion of the sliding prevention metal fitting is hidden behind the butted portion of the outer wall panel and is not exposed outside the outer wall panel. Therefore, the appearance of the outer wall is not impaired by the metal fitting.

[0012] Claims 5 and 6 are those in which the slip-off prevention fitting is taken out alone. Claim 5 is a fitting corresponding to claim 2, and claim 6 is a fitting corresponding to claim 4. As described above, each of the metal fittings is pierced by the flexible material to prevent the metal from slipping.

[0013]

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows an example of an outer wall portion of a building which is perpendicular to a horizontal plane and has a certain thickness, and an outer wall structure portion 1 having a structure for preventing a soft material (glass wool or the like) for filling the inner space of a wall from slipping, and an outer wall surface thereof. It is shown from the side.

The outer wall structure section 1 includes a plurality of outer wall panels 2 forming an outer wall surface of a building, a plurality of vertical hulls 3, a glass wool 4 as a flexible material, and an inner wall surface of the building. And a plurality of slip-off preventing fittings 6 for preventing the glass wool 4 from slipping off. The body edges 3 are arranged at predetermined intervals, and each end of each body edge 3 is fixed to a foundation member and a beam member of the building. An outer wall panel 2 is attached to the outside of the body edge 3, and an inner wall panel 5 is attached to the inside. Glass wool 4 is insulated and soundproofed in a wall interior space formed by the panels 2, 5 and two body edges. Filled for etc. In addition, the sliding prevention metal fitting 6 is in a state of being supported by the outer wall panel 2 in the interior space of the wall.

The outer wall panel 2 is a panel material (a so-called sizing material) such as ceramic formed in a plate shape from an inorganic material. As shown in FIG. A lower end surface having a concave portion 11 having a groove-shaped concave portion 11, and an upper end surface having a convex portion 13 having a convex portion 13 corresponding to the groove-shaped concave portion 11.
Is formed.

The outer wall panel 2 is attached to the rim 3 by a stopper 15 having a shape shown in FIG. Clasp 15
Is formed by bending a flat plate.
6 and integrally has a waist edge fixing portion 17 fixed to the waist edge 3 and a fitting portion 18. The fitting portion 18 is formed on a curved surface corresponding to the butting portions 12 and 14 of the outer wall panel.

As shown in FIG. 4, in order to connect another outer wall panel 2b to an outer wall panel 2a located below, for example, by using a metal fastener 15, first, a convex butting portion of the outer wall panel 2a is joined. The fitting portion 18 of the fitting 15 is fitted into the fitting 14. Next, a screw 19 is passed through the screw insertion hole 16 of the waist edge fixing portion 17, and this is screwed into the waist edge 3 so that the stopper 15
Is fixed. Then, the upper outer wall panel 2b is connected to the lower outer wall panel 2a by fitting the recess butted portion 12 of the upper outer wall panel 2b into the fitting portion 18 of the fastener 15.

In this manner, the upper portion of the lower outer wall panel 2a is fixed, and the lower portion of the upper outer wall panel 2b is supported by the fastener 15. Do the same operation on the upper panel 2
By performing for b and another panel located thereon, a continuous vertical outer wall is formed based on the rim 3. Since the fitting portion 18 of the metal fitting 15 is accommodated in the butting portions 12 and 14 of the outer wall panels 2a and 2b and is not exposed to the outside, the appearance is not spoiled. Further, both side ends of each outer wall panel 2 are smooth surfaces, and the outer wall panels 2 adjacent to each other in the lateral direction are connected by bringing their side ends into contact with each other over the entire surface. Of course, another metal fitting can be used for the lateral connection.

Returning to FIG. 1, the glass wool 4 may be a non-woven inorganic fiber (similar to cotton) in a mat-like form or may be packed in a bag. The vertical and horizontal dimensions of the glass wool 4 at the time of filling are appropriately determined. Generally, a glass wool having a size substantially corresponding to the width of the flexible material filling space formed between the body edges 3 is used.

The inner wall panel 5 is made of, for example, gypsum board.
It has a width at least larger than the interval between the waist edges 3, and cuts a standard product as it is or to a desired width / height.
It is attached to the rim 3 by nails, screws, or the like.

The slip-off prevention metal fitting 6 shown in FIG. 5 integrally includes a flat plate-shaped pin support portion 22, a fixing portion 23 having irregularities, and a pin 24 projecting from the surface of the pin support portion 22. The fixing portion 23 is provided on the outer wall panel 2 so as to prevent the sliding member 6 from slipping.
Are fixed, and the irregularities thereof have the same contour and dimensions as those of the above-described stopper 15. That is, as shown in FIG.
Since the fixing portion 23 is sandwiched between the convex butting portion 14 of the lower outer wall panel 2a and the concave butting portion 12 of the upper outer wall panel 2b, the slip-off prevention metal fitting 6 is fixed to the outer wall panels 2a and 2b. It has become.

The pin supporting portion 22 is integral with the fixing portion 23. When the fixing portion 23 is sandwiched between the outer wall panels 2a and 2b, the inner surface 6a thereof comes into contact with or close to the inner surface 2c of the outer wall panel 2b. They are opposed in parallel. Therefore, the pins 24 erected substantially perpendicular to the outer surface of the pin support 22 face the direction substantially perpendicular to the outer wall panel 2.

The pin 24 is formed by fixing the base end of a metal wire having a sharp tip to the pin support 22 by welding, screwing, or the like. Further, as shown in FIG. 7, for example, the length of the pin 24 is appropriately adjusted so as not to exceed the depth of the inner space of the wall and to be able to stably support the pierced glass wool 4.

Next, an example of the construction using the above-described slip prevention metal fitting 6 will be described with reference to FIG. As shown in FIG. 8 (a), first, the outermost wall panel 2d located at the lowermost end is arranged at a predetermined position in the lateral direction, and the outer edge of the outer wall panel 2d of the convex butting portion 14 formed continuously at the upper end thereof The metal fittings 15 are fitted at a plurality of locations facing the position 3 and are screwed to fix the outer wall panel 2d to the plurality of rims.

Next, as shown in FIG. 8 (b), a predetermined number of anti-slipping metal fittings 6 are fitted into the convex butting portions 14 of the outer wall panel 2d such that the pins 24 thereof face the space inside the wall. . The appropriate quantity of the slip-off prevention fittings 6 is determined based on the interval between the waist edges 3 and the expected weight of the glass wool 4 after absorbing moisture.

Then, as shown in FIG. 8 (c), the outer wall panel 2e connected to the upper side of the outer wall panel 2d is joined to the lower wall of the outer wall panel 2d via the metal fittings 15 with the concave butting portion 12 of the outer wall panel 2e. It is connected to the outer wall panel 2d while being fitted into the part 14. At this time, the plurality of sliding prevention metal fittings 6 are fixed between the butting portions 12 and 14 together with the metal fittings 15.

In this manner, by connecting the outer wall panel 2 to the predetermined height in the vertical direction, as shown in FIG. The fall prevention fitting 6 can be attached. However, when connecting the outer wall panels 2, it is not essential to always hold the slip-prevention metal fittings 6, and the supporting position of the glass wool 4 to be filled is determined first, and the slip-prevention metal fittings are set at a corresponding position and quantity. 6 can also be set.

After the connection of the outer wall panel 2 is completed, FIG.
As shown in (a) to (c), when the glass wool 4 is pressed against the inner surface 2 c of the outer wall panel 2, the pins 24 of the slip-down preventing bracket 6 pierce the glass wool 4 at a plurality of positions, and the glass wool 4 At least a part of the weight is supported, and the glass wool 4 is covered by fixing the inner wall panel 5 as shown in FIG.
When the glass wool 4 is pierced by the pins 24 in this manner, even if the glass wool 4 later becomes heavy due to absorption of moisture, it becomes difficult to slip down. Then, it is naturally dried, and the required heat insulating and soundproofing function can be maintained.

It should be noted that various types of slip-off preventing fittings 6 can be employed, and for example, the projections can be deformed as shown in FIGS. 11 (a) to 11 (e).

FIG. 11 (a) shows some examples of the form of a pin tip, showing a pin tip 32a sharpened like a needle, a pin tip 32b simply cut without sharpening, and a rounded pin tip 32c. If the glass wool 4 has many voids, especially if it is soft, it is possible to pierce even the pointed pins 32b and 32c which are not sharp. Further, the male screw part 31 formed near the screw head of the pin 32 is connected to the pin support part 2 of the sliding-off prevention fitting 6.
The pin 32 can also be fixed to the pin support 22 by being screwed into the female screw hole 46 formed in the second. In this way, the pin 32 and the main body 33 including the pin support portion 22 and the fixing portion 23 can be transported in a separated state, and both can be assembled at the time of construction. In this case, there is an advantage that the packing of the slip-off preventing bracket 6 is not bulky.

FIG. 11 (b) shows the slip-prevention metal fitting 6 which employs a pin 34 having a barbed end. That is, the "key 34a"
The effect is that the glass wool 4 is hardly caught on the key 34a and hardly comes off. Further, as shown in FIG. 11 (c), a pin 35 having a screw protrusion 35a having a helical high thread may be employed, and in this case, the screw protrusion 35a does not easily enter the glass wool 4 and come off. It works.

Further, as shown in FIG.
May not be at a right angle to the pin support portion 22, but may be projected obliquely so that the pin tip faces slightly upward. Thereby, the pin 3
4 becomes difficult to come off from the glass wool 4, and its support becomes more reliable. In this case, the pin 34 is
Any of (a) to (c) may be used.
If it is provided, the further retaining effect can be maintained. Further, as shown in FIG. 11 (e), a curved pin 36 along a curve that rises in an arc shape obliquely upward (or a curve that rises at the tip that is convex downward) may be fixed to the pin support 22. In this case as well, the retaining effect can be obtained, and the knife wool (or ivory) can be easily inserted into the glass wool 4 by being sharpened gradually from the base end toward the front end.

Further, as shown in FIG. 11F, after a pin 48 longer than the thickness of the glass wool 4 is pierced into the glass wool 4, the pin 48 protruding from the glass wool 4 is pierced.
May be bent moderately (for example, substantially at a right angle) by a tool such as a bench or by hand. In this way, the supporting force of the glass wool 4 by the slip-off prevention fitting 6 is particularly enhanced. Here, the shape of the pin 48 is shown in FIGS.
Regardless of (e), any one that can be easily bent can be adopted.

It should be noted that the slip-off preventing bracket 6 is not limited to a metal-made one, but may be made of ceramic, plastic, wood or the like. Further, in the above-described embodiment, glass wool is exemplified as a typical example of the soft material, but the present invention can be applied to rock wool, a soft foam, and other soft materials. In addition, it is obvious that the present invention can be implemented in various modified forms based on the knowledge of those skilled in the art.
