本発明は、鉄筋コンクリート構造等において気
密性を高めるために、鉄板をビン内にライニング
し、且つ同鉄板を構造材として利用する鉄板貼り
コンクリート壁構造の改良に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a steel-plated concrete wall structure in which a steel plate is lined inside a bottle and the steel plate is used as a structural material in order to improve airtightness in a reinforced concrete structure, etc. be.

している。 Conventionally, in this type of structure, stud bolts were used as shear connectors to integrate the steel plate and concrete, and stud bolts b were welded to the inner surface of steel plate a, as shown in Figures 1 and 2. The concrete e is placed inside the concrete by arranging vertical and horizontal reinforcing bars d and d' with spacers c interposed therebetween.

されていた。 In the conventional method, in order to properly weld the stud to the iron plate, it is necessary to consider the minimum thickness of the iron plate with respect to the diameter of the stud bolt. Even when using studs with a diameter of 6 mm, which is the minimum diameter commonly used, a steel plate with a thickness of 3.2 mm or more is required from the viewpoint of weldability, and if the thickness of the steel plate is greater than the thickness calculated from the structural strength. In many cases, the thickness of the steel plate was determined based on the ability of stud bolt welding.

かかる。 In this way, conventional methods require reinforcing bars that are thicker than required for structural strength, making them uneconomical.Since the steel plate thickness exceeds 3.2 mm, it takes time and effort to make an arc shape, and sometimes requires machining. Become. In addition, since stud welding machines are gun-type, the work of refilling stud bolts is required, which requires manpower and is difficult to automate. Furthermore, the stud bolts only function as shear connectors, and the support for the steel plate side needs to be similar to that for the concrete side, which takes time and effort for temporary construction work. Furthermore, stud bolts do not function as reinforcement guides, and require spacers and reinforcing bars, making reinforcement work time-consuming.

A plurality of shear connector members made of perforated channel steel and capable of bearing bending stress in the in-plane direction of the web are arranged at predetermined intervals on the inner surface of the steel plate, and each of the shear connector members is arranged on the inner surface of the iron plate at predetermined intervals. Relating to a concrete wall structure with steel plates, characterized in that one flange part of the member is welded, reinforcing reinforcing bars are provided along the other flange part, and concrete is layered on the inner surface of the steel plate. It is something.

化も容易である。 In the present invention, instead of the conventional stud, a perforated stud is constructed of a pair of parallel flanges facing each other, and a web section that is perpendicular to the flanges and has an opening through which concrete can flow. A shear connector member made of channel steel and having a cross-sectional performance capable of bearing bending stress in the in-plane direction of the web is used, and a plurality of the same shear connector members are arranged at predetermined intervals on the inner surface of a steel plate. Since one flange part of the connector member is fixed to the inner surface of the steel plate, the flange part is spot welded to the steel plate, or both ends of the flange part are fillet welded, and the wall thickness of the flange part is set to the thickness of the steel plate. By making it equal to or less than 2.3 mm, it becomes possible to use thin steel plates with a thickness of 2.3 mm or less, and the thickness of the steel plate can be reduced to the thickness calculated from the structural strength.As a result, materials are saved and costs are reduced. Not only can this be reduced, but the arc processing of the iron plate can be easily performed. Furthermore, the welding work process is simple, the work time can be shortened, and welding can be easily automated.

性能もよい。 Further, since the shear connector member is constituted by a structural member in which both flange parts are connected by a web part, it has the same reinforcement effect of concrete as a steel plate. In this case, since the web portion is provided with an opening through which the poured concrete flows, the filling property of the concrete is good and the adhesion performance with the shear connector member is also good.

化され、仮設作業が簡略化される。 Furthermore, the shear connector member is constructed of a member that has a cross-sectional performance that can bear the bending stress in the in-plane direction of the web, which connects the facing flanges on both sides with the web, so it does not provide the support required during concrete pouring. This eliminates or simplifies construction work in the axial direction of the material, simplifying temporary construction work.

発明は多くの利点を有するものである。 Furthermore, the flange portion of the shear connector member on the opposite side of the flange portion fixed to the steel plate is used as a guide for reinforcing work, and therefore the covering thickness of the reinforcing bars arranged inside the steel plate is the same as that of the shear connector member. The present invention has many advantages, such as being accurately held by the reinforcing rods, eliminating the need for spacers when arranging the reinforcing bars, and simplifying the reinforcing work by simply fixing the reinforcing bars to the shear connector member.
