Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a solid foundation used for a ground, a floor, each floor, a slab, etc. in a reinforcing steel or steel concrete building, and a reinforcing arrangement of columns, beams and the like.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a solid foundation 10 used for a ground, a floor, or the like in a steel bar or a steel concrete building has a reinforcing structure of a bottom foundation 1, 1,. . . Were arranged, and their ends were bent upward, downward or sideways as shown in FIG. 4 to construct a rising muscle structure such as a wall.

[0003]

[Problems to be solved by the invention]

 However, in this case, the bottom main reinforcements 1,1,. . . The bending work of the end of the slab was very expensive and the construction period was prolonged. Strong stress was applied in the event of an earthquake or the like, and the solid foundation or standing structure was easily damaged. In the present invention, the welding is established by a welding structure pre-assembled in a factory instead of bending.

[0004]

[Means for Solving the Problems]

 In the present invention, a plurality of bottom main reinforcements 1, 1,. . . Lap joint bars 2, 2,. . . Are welded to the ends of the lap joints, and these lap joint bars 2, 2,. . . Stirrups 5,5. . This is a reinforcement arrangement structure such as a solid foundation which is formed along the vertical direction. The present invention is also applicable to the above lap joint bars 2, 2,. . The fixing streaks 3 and spot studs 4 are pre-assembled at the factory by spot welding 4, and stirrups 5,5. . . The upper bar 14 and the lower bar 15 of the main bar spot welded to the upper and lower ends of the main bar and the abdominal bar 16 welded in the middle of the bar are previously assembled in a factory by spot welding. . . Are placed on the anterior and posterior sides of the anchor muscle 3, the upper muscle 14, the lower muscle 15, and the abdominal muscle 16 every other or several stirrups. . . This is a reinforcement arrangement structure such as a solid foundation which clamps the fixing streaks 3 to rotate between them.

[0005]

[Embodiment of the invention]

 FIG. 1 shows a first embodiment of the present invention, in which a plurality of bottom main reinforcements 1, 1,. . . Lap joint bars 2, 2,. . . The anchoring wires 3 extending horizontally are spot-welded to the ends of the lap joints 2, 2,. . . Stirrups 5,5,5 at the weld 4 between the . Vertically. The solid foundation 10 shall be at least 15 cm below the ground surface, and shall be dug down to the ground where the design ground strength can be secured, and shall be below the freezing depth of the construction area. The thickness of the bottom plate shall be 15cm or more.

As shown in FIG. 1, in these rising muscle structures 12, each of the lap joint muscles 2, 2,. . The fixing streaks 3 and spot studs 4 are previously assembled at the factory by spot welding 4, and stirrups 5,5. . . The upper main bar 14 and the lower main bar 15 spot-welded to the upper and lower ends of the main bar, and the abdominal bar 16 welded to the middle between them are pre-assembled by a factory by spot welding. The stirrups 5,5. . . Are placed anteriorly and posteriorly to the anchor muscle 3, the upper muscles 14, the lower muscles 15 and the abdominal muscles 16, respectively, so that the stirrups 5, 5,. . . The fixing streaks 3 are pinched so as to rotate. This allows the whole to be folded in one plane, which is convenient for transportation. In FIG. 2, reference numerals 13 and 13 designate lap joint bars 2, 2,. . Auxiliary bars spot welded to

[0007] Since this apparatus has such a configuration, when it is used for constructing the ground and floor in concrete construction, first, the lap joint reinforcement of the reinforcement structure 12 stands on the end on the solid foundation 10. 2, 2,. . . And these lap joint bars 2, 2,. . . The bottom main bars 1,1,. . . Are arranged in parallel to construct the horizontal streak structure 11. These operations are performed as shown in FIG. 5 by using different bottom main bars 1a, 1a,. . . The horizontal streak structure 11 in the form of a lattice is constructed by performing the vertical and horizontal directions together. Thus, the sole bars 1,1,. . . And lap joint bars 2, 2,. . Concrete 6 is horizontally struck on the horizontal bar structure 11 composed of the anchoring bars 3 and stirrups 5,5. . When the concrete 6 is struck perpendicularly to the rising stirrup structure 12 formed as shown in FIG. 5, it is possible to construct a horizontal streak structure 11 such as the ground and floor in a concrete building as shown in FIG. is there. The height of the rising structure 12 is 12 cm or more, and the rising from the ground surface is 15 cm or more.

[0008] Thus, the main sole bars 1,1,. . . And lap joint bars 2, 2,. . Are connected to each other strongly by concrete 6, and the main reinforcements 1, 1,. . . When strong stress is applied to the lap joints 2, 2,. . Further, the stress transmitted to the anchoring muscle 3 is also dispersed to the left and right, and the stress is relieved, so that it is hard to break.

[0009] As shown in FIGS. . . In the direction perpendicular to the second floor main reinforcements 1a, 1a,. . . Are arranged, the second bottom main bars 1a, 1a,. . . It is preferable to provide a similar reinforcing structure such as a solid foundation at the end of the.

[0010]

[Effect of the invention]

 As described above, the present invention firstly provides lap joint bars 2, 2,. . . And these lap joint bars 2, 2,. . . Bottom row where many are arranged on the solid foundation 10 at a time. . . If they are parallel to each other, it is possible to construct the bottom main reinforcement structure and the rising structure, the work on site is extremely easy, the construction period can be shortened, and the construction cost can be provided at low cost. Further, in the present invention, the above lap joint bars 2, 2,. . The fixing streaks 3 and spot studs 4 are pre-assembled at the factory, and stirrups 5,5. . . The upper main bar 14 and the lower main bar 15 spot-welded to the upper and lower ends of the main abdominal muscle 16 and the abdominal muscle 16 welded to the middle between them are spot-welded in a factory in advance, and the stirrups 5, 5,. . . Are placed on the anterior and posterior sides of the anchoring muscle 3, the main muscle upper muscle 14, the main muscle lower muscle 15, and the abdominal muscle 16 every other or several stirrups. . . Since the fixing streaks 3 are pinched so as to rotate between them, the whole can be folded in one plane, which is convenient for transportation.
