Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case in which a wall is constructed with a lightweight cellular concrete wall panel (hereinafter referred to as an ALC wall panel), and an opening portion for mounting an attachment such as a window or a door is provided on the wall. The present invention relates to a reinforcement structure for an opening, which is necessary for

[0002]

2. Description of the Related Art FIG. 11 shows a wall 50 constructed of ALC wall panels 51 and 52 and an opening 53 provided in the wall 50.
Are shown. An attachment (not shown) such as a window or a door is attached to the opening 53, but the opening 53 needs to be reinforced so as to withstand a wind load applied to the attachment. Therefore, conventionally, two right and left vertical reinforcing members (angle members) 54 extending in the vertical direction are attached to the upper and lower beams 55 and the angle piece 5 before the ALC wall panels 51, 52 are built.
6 and the angle bar 57 are welded and fixed, and the upper and lower horizontal reinforcing members 58 (angle members) extending in the lateral direction are fixed to the vertical reinforcing members 54 by welding.
4, the left and right edges of the opening 53 are reinforced, and the lateral reinforcing members 58 reinforced the upper and lower edges of the opening 53. After that, the ALC wall panels 51 are installed on the left and right sides of the opening 53, respectively, and the small ALs are formed on both sides of the opening 53.
The C wall panel 52 is built. According to this opening portion reinforcing structure, the wind load applied to the attachment to the opening portion 53 is
Across the upper and lower beams 55 through the two vertical reinforcements 54,
The LC wall panels 51, 52 have the advantage of not covering.

[0003]

However, since the conventional opening reinforcing structure requires four reinforcing members 54 and 58, especially two vertical reinforcing members 54 which are vertically longer than the opening 53, the cost of parts can be reduced. There was a problem of overcrowding. Also, 4
Since all the reinforcing members 54 and 58 of the book are fixed by welding, it takes a lot of time and labor and the working cost is increased. Further, as shown by the hatching in FIG. 12, a deletion portion 59 corresponding to the thickness of the vertical reinforcing member 54 is cut on a part of the front surface of the left and right ALC wall panels 51 facing the opening 53, Vertical reinforcement 5
Since it was necessary to fit No. 4 in the same plane, it took a lot of time and labor for cutting, and the work cost also increased. In addition, since the step of welding and fixing the four reinforcing members 54 and 58 and the step of subsequently building the ALC wall panels 51 and 52 are clearly separated, the construction period is long.

An object of the present invention is to solve the above-mentioned problems, to sufficiently reinforce the opening, and to eliminate the need for a long vertical reinforcing member which has been conventionally required, and to reduce the number of reinforcing members. It can be installed easily without the need for complicated welding work of the reinforcing material and cutting of the small edge of the ALC wall panel, and the cost can be reduced. Furthermore, it is almost parallel to the installation of the ALC wall panel. Another object of the present invention is to provide a wall opening reinforcing structure that can be installed for a short time and can be installed in a short time.

[0005]

In order to achieve the above object, a wall opening reinforcing structure of the present invention is a structure for reinforcing a wall opening constructed by an ALC wall panel, and is adjacent to the left and right sides of the opening. Anchor members are embedded in a pair of ALC wall panels that are respectively built in, and the left and right ends of the upper edge reinforcement and the lower edge reinforcement that respectively reinforce both the upper and lower edges of the opening are connected to the pair of ALC wall panels. It is characterized in that the upper edge reinforcing material and the lower edge reinforcing material are supported by being applied to the back surface of the above and being joined to the anchor member via the attachment member.

[0006] Here, the "anchor member" is not limited to a particular material and shape, and can be exemplified by a metal pipe, rod, or plate, but among these, the two contradictory conditions of strength and lightness are given. A metal pipe that is easy to fill is preferred. The length of the metal pipe is 160 ± 10m
m, diameter 17.3 ± 3 mm, and wall thickness 3.2 ± 0.5 mm are preferred. This is because a metal pipe within the above range is difficult to bend and the resistance of the ALC wall panel to the tensile force is large (if the length of the pipe is too short, A
The surface of the LC wall panel is apt to crack, and A
It becomes easy to pull out from the LC wall panel).

Also, the "mounting member" is not limited to a specific one as long as it can be coupled to the anchor member, but a bolt that is screwed into the anchor member through a bolt insertion hole formed in the back surface of the ALC wall panel. Can be illustrated. In the case of this bolt, notches or holes provided at the left and right ends of the upper edge reinforcing member and the lower edge reinforcing member can be hooked on the bolt.

[0008] It is preferable that the left and right ends of the upper edge reinforcing member and the lower edge reinforcing member are coupled to the mounting member so as to be rotatable relative to each other.

"Upper edge reinforcement and lower edge reinforcement" are, respectively,
Although not limited to a particular material and shape, a metal angle member having an L-shaped cross section, which includes a lateral surface portion that enters the opening and a vertical surface portion that abuts the back surfaces of the pair of ALC wall panels, can be exemplified. In this case, it is preferable to provide a reinforcing rib on the vertical surface portion to increase the strength of the vertical surface portion.

A description will be given according to the order of construction together with the built-in structure of 1, 15, 15.

(1) The dimensions of the ALC wall panel 1 installed on both the left and right sides of the opening 41 are 600 mm in width, 3000 mm in height and 100 mm in thickness. Prior to the erection, as shown in FIG. 4, two upper and lower anchor insertion holes 3 are formed at upper and lower portions of the left and right long-sided edge faces 2 facing the opening 41. In both anchor insertion holes 3, the upper anchor insertion hole 3 is located 30 mm above the upper edge of the opening 41, and the lower anchor insertion hole 3 is 3 mm below the lower edge of the opening 41.
Drilling guide and diameter 1 so that it is located 0 mm downward.
It is provided by making a hole to a depth of 200 mm with an 8 mm drill (not shown). In addition, bolt insertion holes 5 are formed at positions corresponding to the heights of the upper and lower anchor insertion holes 3 on the back surface 4 of the ALC wall panel 1. Both bolt insertion holes 5 are provided by drilling a position of 90 mm from the forefront surface 2 of the back surface 4 to a depth communicating with the anchor insertion hole 3 in the same manner as the formation of the anchor insertion hole 3.

(2) A length of 1 is provided in the upper and lower anchor insertion holes 3.
A cylindrical steel pipe anchor 6 having a diameter of 60 mm, a diameter of 17.3 mm, and a wall thickness of 3.2 mm is inserted. In the portion of the peripheral wall of the pipe anchor 6 that communicates with the bolt insertion hole 5,
The female screw hole 7 is formed in advance. Then, the shaft portions 10 of the bolts 8 are inserted into the upper and lower bolt insertion holes 5, respectively, and the male screw tips of the shaft portions 10 are shallowly screwed into the female screw holes 7 of the pipe anchor 6 (temporary fixing). The temporary fixing of the bolt 8 prevents the pipe anchor 6 from rotating in the anchor insertion hole 3 and prevents the female screw hole 7 and the bolt insertion hole 5 from being displaced from each other, and the head 9 of the bolt 8 and the rear surface of the panel. 4, a gap slightly larger than the thickness of the vertical surface portions 22, 27 of the upper edge reinforcing member 20 and the lower edge reinforcing member 25 remains.

(3) As shown in FIG. 5, an angle bar 36 welded and fixed to the front end of the upper surface of the beam 35 as a structural body.
A plurality of receiving plates 37 each having an L-shaped cross section are welded and fixed to the front surface of the plate (only a part of which is shown), and the ends of the lower short-sided face are placed on the receiving plates 37, thereby opening 41
ALC wall panels 1 are installed on the left and right sides of each. In addition,
Since the details of this embedding method are not directly related to the present invention, description thereof will be omitted.

(4) As shown in FIG. 6, above the upper edge of the opening 41, the lateral surface portion 21 of the upper edge reinforcing member 20 is inserted between the left and right long side edge surfaces 2 and the vertical surface portion 2 is formed.
The left and right ends of 2 are slidably contacted with the left and right panel back surfaces 4 while being inserted into the gap between the head portion 9 and the panel back surface 4 from above, and the notches 23 are dropped into the shaft portions 10 of the bolts 8 to form the hooking holes. 24 is attached to the shaft portion 10. Tighten the bolt 8 with a tightening torque of 100 cm · kgf,
When the male screw tip of 0 is deeply screwed into the female screw hole 7 of the pipe anchor 6, the upper edge reinforcing member 20 can be supported on the upper edge of the opening 41 as shown in FIG. Lower edge reinforcement 2
5 as well as the upper edge reinforcing member 20, the vertical surface portion 2
The hooking holes 29 of No. 7 are hooked on the shaft 10, and the bolts 8 are tightened to be supported on the lower edge of the opening 41.

The hooking holes 24 and 29 are only hooked to the shaft portion 10, and the left and right ends of the vertical surface portions 22 and 27 are located between the head portion 9 of the bolt 8 and the panel rear surface 4. Since they are only sandwiched by the tightening torque, when a strong external force is applied due to an earthquake or the like, the left and right end portions of the vertical surface portions 22 and 27 are rotatable relative to the bolt 8.

(5) As shown in FIG. 1, the receiving plate 3
7. A small ALC wall panel 15 is built under the opening 41 by placing the end of the short side edge face on top of 7, and a mounting plate attached to the back surface of the ALC wall panel 15 with a bolt 39. 38 is the vertical surface portion 2 of the lower edge reinforcement 25
7 In addition, by mounting the end of the short side edge face on the lateral surface portion 21 of the upper edge reinforcement 20, the small ALC wall panel 15 is built above the opening 41, and the ALC wall panel 15 is The attachment plate 38 attached to the back surface with bolts 39 is locked to the vertical surface portion 22 of the upper edge reinforcing member 20.

According to the wall opening reinforcing structure of the present embodiment, the long vertical reinforcing member which is conventionally required is not required.
The cost of parts can be reduced by reducing the number of reinforcing materials. In addition, the upper edge reinforcing member 20 and the lower edge reinforcing member 25 can be easily attached without complicated welding work,
Since the labor for cutting the small surface 2 of the ALC wall panel 1 can be omitted, the working cost can be reduced. Furthermore, since the upper edge reinforcing member 20 and the lower edge reinforcing member 25 can be installed substantially in parallel with the building of the ALC wall panel 1, the installation period can be shortened.

In addition, in this reinforcing structure, the wind load applied to the attachment to the opening 41 is AL through the pipe anchor 6.
Although it depends on the C wall panel 1, it has been confirmed that the ALC wall panel 1 has sufficient proof stress against the wind load, so that the opening 41 can be sufficiently reinforced.

Further, the upper edge reinforcing member 20 and the lower edge reinforcing member 25
The left and right end portions of the ALC wall panel 1 are not welded and fixed to the ALC wall panel 1 through vertical reinforcing members as in the conventional case, but are rotatably coupled to the bolt 8 through the bolt 8.
It is connected to a pipe anchor 6 embedded inside. Therefore, as shown briefly in FIG. 7, the ALC wall panels 1 and 15 are displaced step by step in response to the deformation of the skeleton (beam 35) due to an earthquake or the like, and exhibit excellent seismic isolation. Even when the wall 40 is constructed by a so-called locking construction method, the upper edge reinforcing member 20 and the lower edge reinforcing member 25 can be independently rotated and slid, so that the rocking performance of the ALC wall panel 1 on both the left and right sides of the opening 41 is improved. There is no need to worry.

The present invention is not limited to the above-described embodiment, but may be embodied with appropriate modifications within the scope not departing from the gist of the invention as follows. (1) Vertical surface portion 2 of the upper edge reinforcement 20 and the lower edge reinforcement 25
Providing reinforcing ribs on 2, 27 to increase the strength of the vertical surface portions 22, 27. In particular, since the lateral surface portions 21 and 26 are not connected to each other near the roots at the left and right ends of the vertical surface portions 22 and 27 and stress is most likely to be concentrated, it is preferable to provide reinforcing ribs near the roots. FIG. 8 shows an example in which two left and right reinforcing ribs 30 made of steel are welded to the rear surface near the roots of the left and right ends of the vertical surface portion 27. 9 and 10 show an example in which the left and right reinforcing ribs 31 are press-formed near the roots of the left and right ends of the vertical surface portion 27.

(2) Replacing the pipe anchor 6 with a rod-shaped or plate-shaped anchor member. (3) The lateral surface portion 21 of the upper edge reinforcement 20 and the lower edge reinforcement 25
Also, the lateral width of the lateral surface portion 26 is expanded to, for example, 1200 mm, and the small ALC wall panel 15 is provided above and below the opening portion 41.
Build two each.

[0025]

As described in detail above, according to the wall opening reinforcing structure of the first aspect of the present invention, the long vertical reinforcing member which has been conventionally required is not required while the opening is sufficiently reinforced. The number of reinforcing materials can be reduced, and the complicated welding work of reinforcing materials and the cutting of the small surface of the ALC wall panel are unnecessary,
It has an excellent effect that it can be easily installed, the cost can be reduced, and the installation period can be shortened by installing the ALC wall panel substantially in parallel with the building.

In addition to the above effects, according to the wall opening reinforcing structure of the second aspect, it is easy for the anchor member to satisfy both of the contradictory conditions of strength and lightness. In addition to the above effects, according to the wall opening reinforcing structure of the third aspect, the upper edge reinforcing member and the lower edge reinforcing member can be easily attached. Further, according to the wall opening reinforcing structure of the fourth aspect, even when the ALC wall panel has locking performance, there is no concern that the upper edge reinforcing material and the lower edge reinforcing material impair the locking performance.

According to the wall opening reinforcing structure of the fifth aspect, the shapes of the upper edge reinforcing member and the lower edge reinforcing member can be simplified. Further, according to the wall opening reinforcing structure of the sixth aspect, the strength of the vertical surface portions of the upper edge reinforcing member and the lower edge reinforcing member can be increased.
