Embodiment Construction

[0052] Next, an embodiment of the concrete frame of the present invention will be described with reference to the drawings. In this embodiment, a case where seismic reinforcement is performed on a concrete frame arranged on the surface of a vertically extending foundation will be described. figure 1 It is a plan view of the concrete frame subjected to seismic strengthening in this embodiment, figure 2 yes figure 1 front view of image 3 yes figure 1 side view. In addition, in the following, for convenience of description, in a concrete frame, the foundation side may be referred to as a "front end side", and the side opposite to the foundation may be referred to as a "rear end side".

[0053]

[0054] Such as Figure 1 ~ Figure 3As shown, the concrete frame 1 of this embodiment is formed on the surface of a vertically extending foundation S, and includes a concrete wall 2 and a steel structure 3 embedded therein. Hereinafter, in the wall surface of the concrete wall...

Abstract

The present invention provides a concrete frame capable of enabling a bending failure to occur before a shear failure, an anti-seismic reinforcing construction method thereof and a clamp used for the construction method. The concrete frame of the present invention comprises: a concrete wall having opposite first and second surfaces; a steel bar construction embedded in the concrete wall; and a plurality of shear reinforcing ribs which are extended in a rod shape on the concrete wall between a first position separated from the first surface at a first distance and a second position separated from the second surface at a second distance, and are dispersely embedded in the concrete wall.

Description

technical field [0001] The present invention relates to a concrete frame, its seismic strengthening (strengthening) construction method and a clamp used in the construction method. Background technique [0002] In concrete frames, for example, buried such as Figure 11 Reinforcement structure is shown, but due to the lack of reinforcement in the Y direction of the figure, there are cases where seismic reinforcement is implemented. In addition, when it is necessary to perform seismic reinforcement of a concrete frame having a limited construction surface such as a retaining wall or a culvert of a structure, construction such as disclosed in Patent Documents 1 and 2 is performed, for example. First, a plurality of long-hole-shaped boreholes are formed from the construction surface of the concrete frame, and a rod-shaped shear reinforcing material is inserted into each of these boreholes. Next, the gap between the drilled hole and the shear reinforcement material is filled wit...
