Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a double wall, which is constructed by forming a lightweight steel-framed board base on a wall made of concrete or the like and pasting a board material thereon. . More specifically, the present invention relates to a double-wall construction method capable of easily performing such double-wall construction and uneven adjustment of the board material.

[0002]

2. Description of the Related Art A partition wall of a reinforced concrete condominium or the like is often a double wall formed by applying a board such as plaster board and finishing the surface.

[0003] In order to put the boards on the concrete wall surface, it is not possible to put them directly. Therefore, a base frame for attaching the board is formed on the concrete surface by using a lightweight steel frame material, and the base frame is placed on the base frame. Boards are attached and fixed by screws or other methods.

[0004] For example, runners made of a lightweight steel material having a channel-shaped cross section are attached to the upper and lower ends of a concrete wall surface, that is, to each of a ceiling slab and a floor slab.
A board base frame is formed by bridging a stud member made of a lightweight steel frame material having a square pipe cross section at a pitch of, for example, 450 mm.

[0005]

However, since the surface of the concrete wall is in a non-land state, a gap is formed between the concrete surface and the board underframe whose upper and lower ends are fixed. If the gap is left as it is, it may not be possible to properly adjust the unevenness of the board surface. In addition, the base frame swings back and forth with respect to the wall surface, and collides with the wall surface to generate vibration noise.

[0006] For this reason, conventionally, at the site side, every time construction is performed, a piece of wood or the like cut to a suitable size is sandwiched between the base frame and the wall surface. However, such countermeasures complicate the construction, take time and effort to adjust the unevenness, and cannot reliably prevent the vibration of the base frame and the like.

An object of the present invention is to propose a method for constructing a double wall, which can adjust the unevenness of the board and prevent the vibration of the base frame by a simple operation.

[0008]

In order to solve the above-mentioned problems, in the method of constructing a double wall of the present invention, the double wall is constructed by the following procedure. First, the upper runner member and the lower runner member are attached to the ceiling slab and the floor slab, respectively. Next, the stud members are bridged between the upper and lower runner members with a constant space. Further, a porous elastic piece impregnated with an adhesive is inserted between each of the stud members and the wall surface. After that, a board material is attached and fixed to the surface side of the stud member by using a screw or the like. After this, an adjuster pin having a pin body that can be driven into the wall surface and a nut screwed onto the outer periphery of the pin body is passed through the board material from the surface side of the board material to the wall surface. By hammering and turning the nut to press the board material against the wall surface side with the nut, the unevenness of each board material is adjusted. Finally, after the adhesive impregnated in the elastic piece is cured, the adjuster pin is pulled out.

In the construction method of the present invention, the distance between the stud member and the wall surface differs depending on the location due to the unevenness of the wall surface or the like, but since the elastic piece is inserted between them, there is a gap. The elastic piece can be easily inserted regardless of whether it is wide or narrow. After inserting the elastic piece, if you stick the board and adjust the board with the adjuster pins, the elastic property of the elastic piece will be lost and the solid piece will have a certain rigidity after the adhesive is hardened. So the board is fixed in the unadjusted condition. Therefore, it is possible to adjust the unsteadiness of the board with a simple operation,
Moreover, since the stud member, which is the base frame, is also securely adhered and fixed to the wall surface, vibration or the like does not occur.

Here, in a preferred embodiment of the present invention, instead of inserting a porous elastic piece impregnated with an adhesive between each of the stud members and the wall surface, before the impregnation with the adhesive is performed. A porous elastic piece is inserted between each of the stud members and the wall surface, and thereafter,
The elastic piece is impregnated with an adhesive.

In order to do so, as the stud member, an adhesive injection hole is formed at a predetermined position in a portion on the side where the board material is attached, and the stud member is used. Insert the elastic piece before impregnating the adhesive between the portion where the adhesive injection hole is located and the wall surface, and then inject the adhesive into the elastic piece through the adhesive injection hole. Good.

By thus inserting the elastic piece into the stud member and then impregnating the adhesive, it is possible to prevent the adhesive from adhering to unnecessary portions. Further, since it is not necessary to handle the elastic piece impregnated with the adhesive, the work of attaching the elastic piece is simplified.

Next, the elastic piece is a portion of the stud member in which the adhesive injection hole is formed in advance, instead of being inserted between the portion of the stud member where the adhesive injection hole is located and the wall surface. Alternatively, the stud member may be bridged over the upper and lower runner members.

On the other hand, as a method of adjusting the unevenness of the board material, instead of using only the adjuster pin as described above, the adjuster pin is used together with the adjuster pin for adjusting the unevenness of the length over at least two stud members. A method using a member (stupid stick) may be adopted. In this case, the unsteadiness adjusting member is applied to the surface of the stud member before the board material is attached, and in this state, the unsteady adjusting member is applied from the surface side of the unsteady adjusting member. Drive the adjuster pin into the wall surface, and then turn the nut of the adjuster pin to adjust the unsteadyness of the stud member through the unadjustable member to impregnate the elastic piece. After the adhesive that has been set has hardened, the adjuster pins and the member for adjusting the unevenness may be removed, and finally the board material may be attached.

Generally, as the stud member, a member having a substantially U-shaped cross section is adopted, and the stud member is arranged such that the opening side of the U-shaped cross section faces the wall surface. May be attached to the stud member by partially inserting it into the U-shaped cross section.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) With reference to FIG. 1, an embodiment of a double wall construction method according to the present invention will be described. First, an upper runner 3 and a lower runner 4 each made of a lightweight steel frame material having a groove-shaped cross section are fixed to a concrete ceiling slab 1 and a floor slab 2 at an interval of about 20 mm from a wall. The runners 3 and 4 are arranged so as to be parallel to each other, and also to be substantially parallel to the wall surface 5.

Next, studs 6 made of lightweight steel aggregate having a C-shaped cross section are vertically spanned between these upper and lower runners 3 and 4 so that the upper and lower ends of each stud 6 are respectively raised and lowered. Fix their positions by inserting them into runners 3 and 4. The upper and lower ends of each stud 6 can be fixed to the upper and lower runners 3 and 4 by screws or the like. Here, the stud 6 is arranged such that the opening side of the C-shaped cross section faces the wall surface 5, and an adhesive injection hole 61 having a diameter of, for example, 7 mm is provided on the bottom of the C-shaped cross section at intervals of, for example, 600 to 900 mm. Is formed.

After the board underframe is constituted by the upper and lower runners 3 and 4 and the studs 6 as described above, the elastic piece 7 made of a porous elastic material is inserted between each stud 6 and the wall surface 5. The elastic pieces 7 can be, for example, in the shape of a rectangular parallelepiped, and one elastic piece 7 is attached to each position corresponding to the adhesive injection hole 61 formed in the stud 6. Here, in the work of mounting the elastic piece 7, as shown in FIG. 1 (C) or (D), the part on one side is pushed into the stud 6 having the C-shaped cross section. By doing so, the attached elastic piece 7 is attached to the stud 6.
Does not come off. The elastic piece 7 may have a shape other than a rectangular parallelepiped.

Further, the material of the elastic piece 7 may be a porous material having elastic properties and capable of being impregnated with an adhesive. Basically, any material may be used as long as the material has these two characteristics.

Next, the elastic piece 7 is impregnated with the adhesive from the surface side of the stud 6 through the adhesive injection hole 61 formed therein using an injection tool such as a spray gun.

The adhesive used may basically be of any kind as long as it has adhesiveness to the wall surface 5 and the stud 6. As shown in the figure, when the concrete wall surface 5 and the stud 6 which is a lightweight steel aggregate are adhered and fixed, for example, a foamable urethane resin liquid is preferably used.

After each elastic piece 7 is impregnated with the adhesive, the plaster board 8 is attached to the surface of the stud 6 by a method such as screwing. After the application of the plaster board 8 is completed, the adjuster pins 9 are driven into the concrete wall surface 5 from the surface side of the plaster board 8 at positions adjacent to the studs 6 through the plaster board 8. 1 (A) and (B)
Shows this state.

The adjuster pin 9 used has a pin body 91 having a pointed tip and a nut 92 screwed to a male screw portion formed on the outer peripheral surface of the pin body 91.

The end surface of the nut 92, which is in contact with the plaster board 8, is a large-diameter board pressing surface 93. After hitting each adjuster pin 9,
Turn 2 to press the surface of the plaster board 8 against the stud 6 side with the board pressing surface 93. Nut 92
By adjusting the position of, the plaster board 8 is adjusted to be unplanned, and the stud 6 is prevented from bulging due to the foaming action of the urethane resin liquid impregnated in the elastic piece 7.

After that, the urethane resin liquid is allowed to stand until it is completely foamed and cured, and then the adjuster pins 9 are removed. Thereby, a double wall with a plaster board can be constructed.

In the construction method of this embodiment, the elastic piece 7 is attached between the wall surface 5 and the stud 6, and then the elastic piece 7 is attached.
An adhesive is impregnated into the adhesive to cure the adhesive. Therefore, even if the wall surface 5 is in a rough state,
The elastic piece 7 can be easily inserted between the wall surface and the stud 6. After the adhesive is hardened, the elastic piece 7 becomes a solid piece and functions as a spacer for holding the space between the wall surface 5 and the stud 6. Therefore, the plaster board 8 stuck on the surface is set flush and free from irregularities. Further, the elastic piece 7, which is a solid piece, functions as an adhesive fixing means for adhesively fixing the stud 6 to the wall surface 5. Therefore, since the stud 6 is securely fixed to the wall surface 5, the adverse effect such as the stud 6 vibrating back and forth does not occur.

As described above, according to the method of this embodiment, the double wall can be constructed by a simple work. Further, adverse effects such as vibration of the base frame can be reliably prevented.

Further, in this embodiment, after the elastic piece 7 is mounted between the wall surface 5 and the stud 6, the adhesive is injected into the elastic piece 7 from the adhesive injection hole 61 formed in the stud 6. Therefore, the elastic piece 7 which has been previously impregnated with the adhesive is used.
Compared with the case where the elastic piece 7 is attached between the wall surface 5 and the stud 6, the elastic piece 7 can be attached more easily. Also,
It is also possible to prevent the adhesive from adhering to unnecessary portions.

Of course, depending on the construction site or the like, it is also possible to adopt a construction method in which the elastic piece 7 is impregnated with an adhesive in advance and this is mounted between the wall surface and the stud. In this case, it is not necessary to form the adhesive injection hole 61 in the stud 6.

In order to impregnate the elastic piece 7 mounted between the wall surface 5 and the stud 6 with the adhesive, the adhesive injection hole 61 is previously formed in the stud 6 in this example. Instead of this, for example, a method of injecting an adhesive from the side of the attached elastic piece 7 can be considered.

As shown in FIG. 3, the concrete wall surface 5 has a dew condensation prevention material 2 made of a heat insulating material such as urethane.
After spraying 1, the double wall may be constructed as described above.

(Second Embodiment) Next, FIG. 2 shows a modification of the construction method of the present invention. In the method shown in the figure, the unevenness adjustment is performed using the adjuster pin 9 and a bar (an idiot bar) for unevenness adjustment.

In this case, the steps of forming the board base frame, mounting the elastic pieces 7 between the studs 6 and the wall surface 5 and impregnating each elastic piece 7 with the adhesive are the same as those in the above first step. It is the same as the embodiment.

However, after this, as shown in FIG.
The unsteady adjusting rod 11 is applied so as to straddle each stud 6, and in this state, the adjuster pin 9 is driven into the wall surface 5 through the unsteady adjusting rod 11. Then, the nut 92 of each adjuster pin 9 is turned, and through the rod 11,
The stud 6 is adjusted to be unsteady, and the stud 6 is prevented from swelling due to the foaming and hardening action of the urethane resin liquid as an adhesive.

After the adhesive is completely cured, the adjuster pin 9 and the rod 11 are removed, and the plaster board 8 is removed.
To the surface of the stud 6 by screwing or the like. In this way, a double-walled board can be constructed. According to the method of this example, the same effect as the above method can be obtained.

[0037]

As described above, in the double-wall construction method of the present invention, the elastic piece impregnated with the adhesive is mounted between the wall surface of the board and the wall surface of the board, which is made of lightweight iron aggregate. The state is formed, and then the board is attached and the unevenness is adjusted in this order or the reverse order. After the adhesive has hardened, the elastic piece functions as a solid piece and functions as a spacer between the wall surface and the board base frame.
It also functions as a means for firmly adhering and fixing the board base frame to the wall surface. The elastic piece can be easily attached, and the board base frame can be surely adhered and fixed to the wall surface even if the distance between the wall surface and the board base frame varies. Therefore, according to the present invention, it is possible to realize a method for constructing a double wall, which is capable of easily preventing a harmful effect such as vibration of the base frame by a simple work.
