ところのコンクリート構造部材接続用目地施工法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing joints for connecting concrete structural members, and more particularly to a method for constructing joints for connecting concrete structural members in which joints are tightly connected to prevent direct contact with concrete. .
従来コンクリート構造部材を接続する場合、例
えば凸凹のパネル端縁同志を接当させ、残留隙間
である目地にパネルと同質のセメントモルタルを

用いられる密着性、塗工性の良いしつくい（漆
喰）ではコンクリートパネルのコンクリートと接
触すると化学反応を生じて亀裂を発生し、目地材
として用いることが出来ないという問題点があつ
たためである。 Conventionally, when connecting concrete structural members, for example, uneven panel edges were brought into contact with each other, and the remaining gaps, or joints, were coated with cement mortar of the same quality as the panels. This is because plaster (stucco), which is commonly used for construction and has good adhesion and coating properties, causes a chemical reaction and cracks when it comes into contact with the concrete of concrete panels, making it impossible to use it as a joint material. This is because a problem arose.
なおここにいうしつくいは石灰、ツノマタ（ま
たはギンナンソウ、フノリなどの海藻も用いる）、
すさ（麻の短繊維）等の混合物である。 Note that the base used here is lime, tsunomata (or seaweed such as ginnansou and funori),
It is a mixture of hemp fibers (short hemp fibers), etc.
また上記セメントモルタルの代わりにゴム質の
パテ、あるいはアスフアルトモルタル等が用いら
れる事もあるが、パテは耐候性に劣ることはいう
迄もなく、またアスフアルトモルタルも、熱に弱
いため耐火構造の建築物には使用出来ないという
欠点があつた。 In addition, rubber putty or asphalt mortar are sometimes used instead of the cement mortar mentioned above, but it goes without saying that putty is inferior in weather resistance, and asphalt mortar is also sensitive to heat, so it is not suitable for fireproof construction. The drawback was that it could not be used for objects.
そこで本発明者は密着性、塗工作業性、耐候
性、耐熱性のいづれにも優れた日本古来のしつく
いを目地材として適用すべく工夫を重ね、種々実
験の結果本発明に到達した。 Therefore, the inventor of the present invention has repeatedly devised ways to apply an ancient Japanese method as a joint material, which has excellent adhesion, workability, weather resistance, and heat resistance, and has arrived at the present invention as a result of various experiments. .
本発明の目的は、しつくいを用いて強固かつ亀
裂の生じない接続目地が得られ、従つて漏水がな

る。 An object of the present invention is to provide a method for constructing joints for connecting concrete structural members, in which a strong and crack-free connection joint can be obtained using staking, and therefore a connection joint with no water leakage and excellent watertightness can be obtained. That's true.

接続用目地施工法が提供される。 According to the present invention, when connecting a plurality of concrete structural members, a flange made of a thin metal plate is embedded in the connecting edge of the concrete structural member in advance, and then, in the process of forming the overlapping part of the flange into a triangular or square cross section. A method for constructing joints for connecting concrete structural members is provided, which comprises inserting a stiffener into the joint and then crushing the overlapping portion of the flange.

As shown in the figure, a thin metal plate 3 is inserted into the connecting surface of the concrete part 2 to form a flange. The thin metal plate is inserted before the concrete part 2 is formed by pouring fresh concrete into a concrete formwork (not shown), and is firmly fixed to the concrete part after the concrete hardens. In addition, a large number of holes are drilled in advance in the part where the thin metal plate is embedded in concrete to sufficiently strengthen its adhesion.

である。 Figure 2 shows a state in which the upper sides of the thin metal plates 3 and 4 that form the flanges of a pair of concrete structural members are bent by approximately 90 degrees to stand up, and the lid portions 3A and 4A and the lower portions are left as they are to form the bottom portions 3B and 4B. FIG.

（薄金属板）への結合を強固にする機能を果たす。 Figures 5, 6, and 7 show the state in which thin metal plate cover parts 3A and 4A are overlapped, crushed or pressed to eliminate any gaps, and then bent so that the overlapping parts do not protrude from the joints. FIG.
FIG. 8 is a sectional view showing the state shown in FIG. 7, which is further finished by coating the joints with cement mortar. As seen in FIGS. 7 and 8, the overlapping portion 11 of the thin metal plates serves to strengthen the bonding of the cement mortar to the joint foundation (thin metal plate).
