Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall for building interior and
The present invention relates to a partition wall and a construction method for the wall, and particularly to a wall without using a light steel frame foundation or a wooden foundation and the construction method.

[0002]

2. Description of the Related Art In non-combustible structures such as reinforced concrete and steel reinforced concrete, after the skeleton is completed,
It is common to partition the room to create a room if necessary. In the building of non-combustible structure such as the above-mentioned reinforced concrete, it is desirable that the wall is also a wall made of non-combustible material, and in most cases, it is a readily available material such as a lightweight steel frame base such as gypsum board or silica board. The wall base plate is stretched to form the wall base.

FIG. 7 shows an example of the structure of a wall which is conventionally well constructed. As shown in the figure, channel-shaped runners (not shown) are attached to the upper and lower floor slabs so as to face each other, and studs (lightweight steel frames) 11 are installed between the upper and lower runners at regular intervals. Runner and stud 1
A lightweight steel base is created with 1. And stud 1
Wall base plate 12 such as gypsum board or silica plate from both sides of 1
Then, the wall base plate 12 is fixed to the studs 11 with a fixing tool such as a screw 7 to finish the wall base.

[0004]

With the conventional wall construction method,
Studs are used inside the wall as a lightweight steel foundation. According to the current building regulations, when a fire occurs inside or outside the building, the temperature of the steel frame prevents the strength of the wall from falling and the wall from collapsing. There is a limit so that it will not exceed the temperature. Of course, if the wall base plate such as gypsum board or silica plate that is stretched on the lightweight steel frame base is thickened so that heat does not easily pass, it is possible to suppress the temperature rise of the steel frame. You can, but that would result in a significant cost increase. For this reason, there has been a demand for a wall that is inexpensive and economical, can achieve good results in terms of fire resistance, and has sufficient strength. An object of the present invention is to provide a wall that solves the above problems and a method for constructing the wall.

[0005]

In order to achieve the above object, the present invention provides a wall having a predetermined thickness by applying a wall base plate to both sides of runners which are arranged above and below the floor of a frame. The wall base plate is separated from each other by cutting lines formed on both sides of the wall base plate, and has a bottom plate portion and a side plate portion that are held together by a protective sheet attached to the surface of the wall base plate. Is formed into a channel shape by the above, and the wall base plate is arranged on the runner so that the bending directions of the side plates of the channel shape are adjacent to each other, and between the adjacent side plate portions, the channel is formed. Reinforcing metal fittings that are bent so as to follow the shape are provided, and the adjacent side plate portions are fixed by a fixing means.

The reinforcing metal member may be made of a strip-shaped steel plate bent in a zigzag manner along the inside of the channel-shaped bent portions of the plurality of wall base plates arranged in the runner.

Further, the reinforcing metal member may be formed of a substantially hook-shaped steel plate having two oppositely bent portions along the side plate portion and the bottom plate portion which are adjacent to the wall base plate.

Further, the wall construction method according to the present invention includes one of the first step of disposing the runners on the upper and lower floor slabs of the skeleton so as to face each other, and the protective sheet disposed on both sides of the wall base plate. Leaving the protective sheet, and through the cutting lines on both sides of the wall base plate, the side plate part of the one wall base plate separated into a bottom plate part and a side plate part is perpendicular to the bottom plate part. A second step of bending the bottom plate part to the side surfaces of the upper and lower runners by bending the bottom plate part into a channel shape, and a reinforcing metal fitting along the bottom plate part and the side plate part that are bent at a right angle of the one wall base plate. And a third step of arranging the other wall foundation plate on the runner so as to be adjacent to the one wall foundation plate so that the bending directions of the side plate portions are opposite to each other. The side plate part of one wall base plate and the side plate part of another wall base plate are fixed by the fixing means via the Characterized by comprising a fourth step that.

The present invention will be further described. The inventor considered removing the light steel frame from the wall so that the temperature rise of the light steel frame (stud) would not be a problem at the time of fire, but the light steel frame is an important structural material for maintaining the strength of the wall. From this, I realized that simply removing this would not function as a wall. Therefore, in the present invention, the light-weight steel frame is not used, but instead, a structural material that becomes the bone of the wall is formed by a part of the wall finishing material, and a reinforcing function in place of the light-weight steel frame is provided to make the wall self-supporting. It is made possible and can maintain its strength.

In the present invention, when a gypsum board, for example, is used for the wall base plate, channel-shaped runners are attached to the upper and lower floor slabs so as to face each other at the place where the wall is to be constructed. Next, I want to put plasterboard from both sides of the runner, but it does not become a wall as it is. Therefore, since a protective sheet is attached to both sides of the gypsum board, leaving only the backing paper, making a notch in both sides in the longitudinal direction of the gypsum board and the cover, separating the bottom plate part and the side plate part, By bending the side plate portion at a right angle to the bottom plate portion, a channel-shaped wall base plate in which the bottom plate portion and the side plate portion are held by the protective sheet is formed.

This channel-shaped wall base plate is screwed to the side surfaces of the upper and lower runners. In this case, both longitudinal ends of the side plate portion collide with the inner end portion of the runner, so both longitudinal end portions of the side plate portion are cut off by the rising dimension of the runner. In this way, the bottom plate portion of the channel-shaped wall base plate, in which both longitudinal ends of the side plate portion are cut off, is fixed to both side surfaces of the runner with screws. In this case, a plurality of wall foundation plates are screwed to the runners with the channel side plates bent in the opposite directions, and each wall foundation plate has strength as a wall. By using the reinforcing metal fittings that are bent and formed, sandwich the reinforcing metal fittings between the side plate parts of the adjacent wall finishing plates, and screw both side plate parts (and adhesive).
If fixed by, the adjacent wall base plates are firmly connected to each other.

A plurality of reinforcing metal fittings may be arranged horizontally at appropriate intervals when it is considered necessary for strength depending on the height of the wall. Further, if the joints between the reinforcing metal fittings are also arranged at different positions, the strength is further improved. As described above, the channel-shaped wall base plates are connected by arranging the side plate portions so that the bending directions of the adjacent side wall base plates are alternately opposite to each other. If is fastened with an adhesive and staples, the wall will have sufficient strength and rigidity.

[0013]

According to the present invention, the side plate portion of the wall base plate, which is perpendicular to the bottom plate portion, serves as a bone, and performs the same function as a conventional lightweight steel frame. That is, when the side plate portions of adjacent channel-shaped wall base plates are fixed by a fixing means such as an adhesive or a screw, considerable rigidity is exhibited. In addition, the reinforcing metal fitting improves the lateral joint strength of the wall base plate. By using a plurality of the reinforcing metal fittings according to the height of the wall, the reinforcing metal fitting serves as an anti-sway effect of the wall and becomes a very strong wall.

[0014]

Embodiments of the present invention will now be described with reference to the drawings. In FIGS. 1 and 2, channel-shaped runners 1 and 1 are arranged at positions where a wall is constructed with upper and lower floor slabs (not shown), and a wall base plate 2 made of, for example, gypsum board 2
On the side of runners 1, 1. A protective sheet (not shown) is attached to both sides of the wall base plate 2 of the gypsum board, and notches 3 are formed on both sides of the cover and the wall base plate 2 in the longitudinal direction while leaving only the backing paper of the protective sheet. And the wall base plate 2 is separated into the bottom plate portion 5 and the side plate portion 4 through the notch 3, and the side plate portion 4 is bent at a right angle to the bottom plate portion 5 toward the inside thereof, thereby forming a protective sheet. The channel-shaped wall base plate 2 in which the bottom plate portion 5 and the side plate portion 4 are held is constituted by the.

As shown in FIG. 1, the bottom plate 5 is formed by notching the longitudinal end portions 8 of the side plate 4 bent inwardly in the bottom plate 5 by the rising dimension of the runners 1, 1. When the part 5 is applied to the side surfaces of the runners 1, 1, both ends of the side plate part 4 do not hit the runners 1, 1. The bottom plate portion 5 is fixed to the side surfaces of the runners 1, 1 with screws 7.

Next, a reinforcing metal member 6 made of a strip-shaped steel plate bent in a continuous concavo-convex shape along the inside of the wall base plate 2 formed by bending the bottom plate portion 5 and the side plate portion 4 into a channel shape.
To form. Then, as shown in FIG. 1, the wall base plates 2 are arranged so that the channel-shaped side plate bending directions are opposite to each other (that is, they are arranged in a staggered manner), and along the longitudinal direction of the runners 1, 1. To install. At this time, the reinforcing metal fitting 6 is interposed between the adjacent side plate portions 4 and 4, and the side plate portions 4 and 4 are fixed with screws (and an adhesive) 7.

With this structure, the reinforcing metal fittings 6 are sandwiched between the side plate portions 4 and 4 which are joined adjacent to each other, and the connection between the side plate portions 4 and 4 and the bottom plate portion 5 is strengthened via the reinforcing metal fittings 6. As a result, a channel-shaped side wall can be formed in a zigzag arrangement with the front and back sides bent. The reinforcing metal member 6 made of a strip-shaped steel plate not only reinforces the channel-shaped wall base plate 2 alone, but also functions as a reinforcing material for the entire wall, and also serves as a steady rest for the wall. When a plurality of base plates 2 are arranged in parallel above and below, the strength of the wall is further improved.

FIG. 6 shows a reinforcing metal fitting 6a which is slightly different from the above. The reinforcing metal fittings 6a are arranged along the corners of the side plate portions 4 and 4 of the wall base plate 2 that are adjacently arranged and the bottom plate portions 5 and 5 positioned at right angles to both ends thereof.
It is formed in a substantially “hook” shape having one bent portion 13, 13. This reinforcing metal member 6a is also arranged so as to be sandwiched by the side plate portions 4 and 4 as in the case of FIG. 4, and thereby the coupling strength between the side plate portions 4 and 4 and the bottom plate portions 5 and 5 is improved.
It becomes a strong wall foundation. As described above, by mounting the wall finishing plate 9 on the wall base plates 2 and 2 arranged on both sides of the runners 1 and 1 with the adhesive and the staples 10, the rigidity is improved without using the light steel frame (stud). A large wall foundation is completed.

[0019]

According to the present invention, by cutting both sides of the wall base plate, a bone replacing the light steel frame base can be formed by a part of the wall finishing plate, and despite the absence of the light steel frame base. A wall with high mechanical strength can be created. The wall base plate is a gypsum board or a silica plate, and a part of the side plate has a high heat resistance and can be used without being affected by the temperature of the steel frame base, which is restricted by building regulations. Moreover, since the side plate portion that substitutes for the steel frame base can be formed by cutting the side part of the wall base plate, the structure is simple and the cost can be reduced.

Furthermore, according to the present invention, there is no need for the conventional two job categories of constructing a lightweight steel frame and upholstering of a wall base plate (plaster board etc.), and one type of worker who is familiar with the construction of a wall base plate. It is also convenient that the whole can be constructed with. In addition, the channel-shaped wall base plates are arranged next to each other so that the side plate bending directions are opposite to each other, and are arranged in a zigzag shape on the runner as a whole. Since it is firmly connected, the wall can have sufficient strength, and the space inside the channel shape can be filled with sound absorbing material such as glass wool and rock wool if necessary, which results in acoustic Also gives good results.
