により窓部を形成する。(Prior art and problems) Conventionally, in order to provide an opening in a lightweight concrete panel, a substantially rectangular frame was constructed by vertical steel frames 11, 11 and horizontal steel frames 12, 12, as shown in Fig. 3. However, a steel frame is constructed by joining vertically reinforcing steel frames 13, 14 and horizontally reinforcing steel frames 15, 16, respectively, around the area where the opening is to be formed. Then, this steel frame is placed within a concrete form, and lightweight concrete is cast flat or vertically to create a lightweight concrete panel P as shown in FIG. 1. This lightweight concrete panel P has an opening W approximately in the center, and a window is formed by fitting a glass plate into the opening via a sash frame (not shown) or directly at the end of the opening. .
一方、軽量コンクリートパネルＰはそれ自体が

部応力が伝達される。 In any case, the lightweight concrete panel P is subjected to external stress in the horizontal and vertical directions, and the external stress is transmitted in the in-plane direction of the lightweight concrete panel P.

た。 At this time, vertically reinforced steel frame 1 as shown in Figure 3 above
3 and 14 and the horizontal reinforcement steel frames 15 and 16, the length depends on the bending strength of the effective cross section of each steel frame, and external stress is also transmitted as in-plane stress to the glass plate fitted into the opening. Ru. When this in-plane stress is large, problems such as cracking at the corners of the opening and damage to the glass plate also occur. Furthermore, the larger the opening, the greater the stress applied to the glass plate, making it impossible to obtain a sufficient aperture ratio of the wall.

な丈でなくパネルの重量が大幅に増大するという
新たな欠点を生じさせた。 Therefore, as shown in Utility Model Application Publication No. 53-55214, it was considered to incorporate a frame frame only around the opening for reinforcement, but it was difficult to deal with the external stress transmitted as in-plane stress of the panel as a whole. In addition to insufficient length, the new drawbacks were that the weight of the panel increased significantly.

合させる。(Summary of the invention and practical examples) The structure of the steel frame reinforcing the concrete panel opening of the invention is as shown in Fig. 2.
1 and horizontal frame steel frames 2, 2 are assembled into a substantially rectangular shape and joined by welding or the like to form a steel frame. and opening W
Vertical reinforcing steel frames 3, 3 are provided at positions having a certain covering thickness from the periphery of the opening. This vertically reinforced steel frame 3,3
is joined with the ends in contact with the horizontal frame steel frames 2, 2.
一方、同様にして横方向に横補強鉄骨４，４を

周縁から一定の被り厚を有する位置に設けられ、
前記縦補強鉄骨３，３とほぼ直交状態にて接合
し、その端部も後述の中間鉄骨に接合される。 On the other hand, horizontal reinforcing steel frames 4, 4 are provided in the lateral direction in the same manner. These horizontal reinforcing steel frames 4, 4 are also provided at a position having a certain covering thickness from the opening periphery of the opening W,
It is joined to the longitudinal reinforcing steel frames 3, 3 in a substantially orthogonal state, and its ends are also joined to an intermediate steel frame, which will be described later.

て溶接により接合する。しかも横補強鉄骨４，４
の各端部はこれら中間鉄骨５，５とほぼ直角状態
にて接合される。 Separately from each of these reinforcing steel frames, intermediate steel frames 5, 5 are erected near the longitudinal reinforcing steel frames 3, 3, outward from the position where the so-called opening W is formed. The intermediate steel frames 5, 5 also have their ends abutted against the horizontal frame steel frames 2, 2 and are joined by welding. Moreover, horizontal reinforcement steel frame 4,4
Each end portion of is joined to these intermediate steel frames 5, 5 at approximately right angles.
斯かる補強鉄骨及び中間鉄骨の接合状態を順次

横枠鉄骨２との接合点をａ、横補強鉄骨４，４と
直角方向の接合点をｂ，ｃ及び他の端部と横枠鉄
骨２との接合点をｄとする。 The joint state of the reinforcing steel frame and the intermediate steel frame will be explained sequentially using symbols. First, the joint point between the upper end of the intermediate steel frame 5 and the horizontal frame steel frame 2 is a, the joint point perpendicular to the horizontal reinforcing steel frames 4, 4 is b, The junction point between c and the other end and the horizontal frame steel frame 2 is designated as d.
同様に縦補強鉄骨３の端部と横枠鉄骨２，２と

３においても同様に、それぞれｍ，ｎ，ｏ，ｐの
各接合点を有する。更に又、他の中間鉄骨５も
ｉ，ｊ，ｋ，ｌの各接合点を有する。 Similarly, the joint points between the ends of the vertical reinforcement steel frame 3 and the horizontal frame steel frames 2, 2 are assumed to be e, h, and the joint points perpendicular to the horizontal reinforcement steel frames 4, 4 are assumed to be f, g. Similarly, other vertical reinforcing steel frames 3 each have m, n, o, and p joint points. Furthermore, the other intermediate steel frame 5 also has i, j, k, and l joint points.
以上の様に構成された鉄骨体において、接合点

間鉄骨によつて仕切られた部分は剛域的な面を有
することになる。 In the steel frame constructed as described above, each of the joint points a to p is rigidly connected by welding, so when concrete is placed there, the concrete is poured into the interior divided by each joint point. Since this is satisfied, the area partitioned by the horizontal frame steel frame, horizontally reinforced steel frame, vertically reinforced steel frame, and intermediate steel frame has a rigid area surface.
すなわち、接合点ｇ−ｆ−ｎ−ｏとそれを囲む
接合点ａ−ｄ−ｌ−ｉがなす領域（第２図斜線部
分）は所謂剛構面を形成する。 That is, the area formed by the junction point g-f-n-o and the surrounding junction points a-d-l-i (the shaded area in FIG. 2) forms a so-called rigid surface.
この剛構面のうち接合点ａ−ｄ−ｅ−ｈと接合
点ｐ−ｍ−ｌ−ｉに各々囲まれた部分は、開口部
ｗの左右に内設された剛構面として「柱」や「方

同様に接合点ａ−ｂ−ｊ−ｉに囲まれた領域は
「まぐさ」としての構面、接合点ｃ−ｄ−ｌ−ｋ
に囲まれた領域は「窓台」としての構面となる。 Similarly, the area surrounded by the junctions a-b-j-i is a "lintel" structure, and the area surrounded by the junctions c-d-l-k
The area surrounded by will serve as a "window sill."
更に接合点ａ−ｂ−ｇ−ｈ、接合点ｃ−ｄ−ｅ

り以上に補剛する構面となる。 Furthermore, junction point a-b-gh, junction point c-d-e
-f, junction n-m-l-k, junction po-j
Since each region -i has a smaller area than the above-mentioned rigid structure surface, its rigidity is also large, and as a result, the structure surface stiffens each corner of the opening W even more.
以上の様な構成を有する鉄骨体に開口部を除い
てメツシユ筋等を貼設し、該型枠に軽量コンクリ
ートを打設する。 Mesh reinforcement etc. are attached to the steel frame having the above-described structure except for the openings, and lightweight concrete is poured into the formwork.

くは「方立」が形成された状態となる。 The lightweight concrete panel P shown in FIG. 1 delivered through the above process has a "lintel" at the top and a "window sill" at the bottom as described above inside the opening W. In addition, "columns" or "mullets" are formed on both sides.

周辺のみならず軽量コンクリートパネルＰ全体が

隅部には小面積の剛構面が形成される為開口部の
入隅は十分に補剛されることになる。 Therefore, these "lintels", "window sills", and "columns" or "mullets" are also in rigid contact with the rectangular steel frame formed by the vertical steel frame 1 and the horizontal steel frame 2, so they are integrated within the panel. As a result, external stress in the in-plane direction of the lightweight concrete panel P is resisted, and not only the periphery of the opening W but the entire lightweight concrete panel P is sufficiently reinforced. Furthermore, since a small-area rigid surface is formed at the outer corner of the opening, the inner corner of the opening is sufficiently stiffened.
本考案者は、例えば約4700mm、高さ約2700mm、
パネル厚約120mmの軽量気泡コンクリートパネル
において、開口率がおおよそ８％を超える場合、
縦補強鉄骨からおおよそ１ｍ以内に中間鉄骨を設

ことを知見した。 The inventor of this invention, for example, has a height of approximately 4700 mm, a height of approximately 2700 mm,
For lightweight aerated concrete panels with a panel thickness of approximately 120 mm, if the open area ratio exceeds approximately 8%,
It has been found that by providing an intermediate steel frame within approximately 1 m from the longitudinal reinforcing steel frame, it is possible to sufficiently cope with the normally expected stress.
尚、上記説明における縦、横枠鉄骨及び各補強
鉄骨、中間鉄骨は、軽量型鋼材が用いられる。 In addition, lightweight steel materials are used for the vertical and horizontal frame steel frames, each reinforcing steel frame, and intermediate steel frame in the above description.

A horizontal reinforcing steel frame and an intermediate steel frame are provided, and by rigidly contacting them, rigid areas such as ``lintels'', ``window sills'', and ``pillars'' are formed within the panel, and they are integrated with the frame steel frame within the panel surface. This increases the rigidity of the entire lightweight concrete panel.Whether the lightweight concrete panel is used as a structural wall or curtain wall, it protects the area around the opening, especially the four corners, from external stress applied in the in-plane direction of the panel. It becomes possible to protect. In addition, the wall opening ratio can be extremely large, and the weight can be reduced compared to the conventional framework panel in which reinforcing bars are wound around a steel frame.
