Description

[Detailed explanation of the idea] Industrial applications This invention relates to reinforced concrete structures.

Problems with the Prior Art Usually, in the beam portion of a reinforced concrete building, a plurality of stirrup reinforcements are arranged so as to wrap around the beam main reinforcement.

However, this type of stirrup is extremely troublesome to process because it is formed by bending it into a substantially U-shape to match the cross-sectional size of the beam and attaching hooks to both ends of the stirrup. Further, due to the shape, reinforcing work was extremely troublesome.

Purpose of the invention This invention was proposed to solve the above-mentioned conventional problems, and by simplifying the reinforcement work for stirrup bars in beams, it saves labor and shortens the construction period for reinforcing steel work as a whole. The purpose is to provide a reinforced concrete structure that can

Structure of the device This device matches the width of the beam of a reinforced concrete building with the thickness of the wall, and also installs wall reinforcing bars outside the upper and lower main beam reinforcement bars arranged in the beam section by extending from the beam section to the wall section. The above object is achieved by arranging reinforcement and connecting the left and right upper end beam main reinforcements and the left and right lower end beam main reinforcements with width stop bars arranged at predetermined intervals in the longitudinal direction.

Embodiment Below, this invention will be explained by an example illustrating the invention. The drawing shows a beam part of a reinforced concrete building according to this invention. The beam part 1, together with the wall part 2 and the slab part 3, is made of reinforced concrete. The beam width of the beam portion 1 is made to match the wall thickness of the wall portion 2.

The required number of upper end beam main reinforcements 4, 4 and lower end beam main reinforcements 5, 5 are arranged at the upper and lower end parts of the beam part 1, respectively, and the left and right upper end beam main reinforcements 4, 4 and the left and right lower end beam main reinforcements 5, 5 are arranged. are connected by width stop reinforcing bars 6, 6, respectively. The width stop reinforcing bars 6, 6 are arranged at predetermined intervals in the longitudinal direction of the upper end beam main reinforcing bars 4, 4 and the lower end beam main reinforcing bars 5, 5.

In addition, auxiliary reinforcing bars 7, 7 are arranged in multiple stages between the upper and lower beam main reinforcements 4, 5, and the left and right auxiliary reinforcing bars 7, 7
are connected by width stop reinforcing bars 6, 6.

On the outside of the upper and lower end beam main reinforcements 4 and 5 of the beam part 1,
Left and right vertical reinforcements 8, 8 doubly arranged inside the wall part 2
The reinforcement is arranged to extend in the vertical direction of the beam portion 1. When extending the left and right wall longitudinal reinforcements 8, 8 in the beam portion 1, the upper ends of the wall longitudinal reinforcements 8, 8 in the wall portion 2 located directly below the beam portion 1 are extended, or The lower end portions of the wall longitudinal reinforcements 8, 8 in the wall portion 2 located above are extended, or the upper and lower end portions of the wall longitudinal reinforcements 8, 8 are extended alternately in the longitudinal direction of the beam portion 1. Alternatively, it may extend between the wall portions 2 located above and below the beam portion 1.
In addition, the spacing between reinforcing bars can be narrowed by increasing the amount of reinforcement in areas that are subject to large shearing forces.

Effects of the invention This invention has the above-mentioned configuration. According to this invention, the vertical wall reinforcement of the wall part can also be used as the stirrup reinforcement of the beam part, so the conventional stirrup reinforcement and its reinforcement work are omitted. As a result, the overall reinforcing bar work can be labor-saving and the construction period can be significantly shortened.

Claims (1)

[Scope of utility model registration request] The beam width of the reinforced concrete building should match the wall thickness, and vertical wall reinforcements should be placed outside the upper and lower main beam reinforcements arranged within the beam section, extending from the beam section to the wall section, and the reinforcements should be placed at the upper left and right edges. A reinforced concrete structure characterized in that the main beam reinforcements and the left and right lower end beam main reinforcements are connected by width stop bars arranged at predetermined intervals in the longitudinal direction.
