Description

Combined bending / shear stiffener for foundation structure

The present invention relates to a combined flexural / shear shear stiffener for the basic structure that can be commonly used in the construction of reinforced concrete foundation structure, more specifically, the flexural / shear combined reinforcement for the basic structure of the present invention is the lower flexural stiffener, upper position fixing And a self-supporting connecting member is a flat bar having holes formed at regular intervals, and a vertical shear reinforcing member is a steel bar having a threaded bolt formed at an end thereof, and the members are connected by a binding means such as a bolt and a nut. The present invention relates to flexural / shear combined stiffeners for basic structures, which are simply assembled and fabricated (hereinafter, referred to as “flexible / shear combined stiffeners”).

In general, tie girder, which is sometimes used for reinforcement of shear in the foundation of reinforced concrete structures, should be fitted with the lower end of the base beam to the base reinforcing bar. Since the installation must penetrate through the upper part of the roots, the work speed on the site decreases and the work fatigue increases, which causes the workers to avoid shear reinforcement.

In particular, if the upper member of the foundation is a column, shear reinforcement may be made in the form of underground beams, but if the upper member is a bearing wall, the shear reinforcement of the underground beam cannot be performed, so the thickness of the foundation concrete is increased instead of reinforcement by the reinforcement. The concrete was designed to bear more of the shear stress acting on the foundation, so there was a problem such as the amount of concrete used.

Therefore, in order to solve the above problems, the present inventors have already applied for a patent for bending / shearing combined reinforcement of reinforced concrete foundation structures, and have already been registered as Patent Publication No. 403835 (registered on October 18, 2003). 1A relates to a perspective view of a bending / shear combined reinforcement having the column reinforcement arranged on the upper part of the foundation structure, and finally reinforces the pillar reinforcement on the bending / shear combined reinforcement 100 according to the position of the pillar. 1B is a perspective view of a bending / shear combined reinforcement 100 having a wall reinforcement disposed on an upper portion of the foundation structure, and installs the bending / shear combined reinforcement 100 one by one according to the position of the bearing wall. Finally, the reinforcing bar reinforcement to the upper wall reinforcement (52) according to the heat of the wall.

The member used as the lower flexural stiffener 10 and the vertical shear stiffener 30 in the above is a reinforcing bar (2a) or flat steel (2b) or angle (2c) as shown in Figures 2a to 2c and 3a to 3c. ), And the upper position fixing material 20 is used to fix the position of the vertical shear stiffener 30 using a reinforcing bar or wire mesh as shown in Figures 4a and 4b.

And as shown in Figure 5a as a means for binding the respective members, the upper position fixing member 20 and the lower flexural stiffener 10 is bound to each other with the vertical shear stiffener 30 using the binding line 60 or As shown in FIG. 5B, the members are assembled by using the tie line 60 and the clip 70 in parallel.

However, the conventional flexural / shear combined stiffener 100 uses rebar or flat steel or angle as the lower flexural stiffener 10 and the shear stiffener 30, whereas rebar or wire mesh is used as the upper position fixing material 20. Not only the shape of each member is different, but the means for binding each member also uses the binding line 60 only, or uses the binding line 60 and the clip 70 in parallel, or binds by welding. There is a problem that the binding work is very inconvenient and takes a lot of time because it is not uniform.

Therefore, the present invention is devised to solve the above problems,

The flexural / shear combined reinforcement of the present design uses flat steel with holes at regular intervals except for the vertical inter-stiffener, which is a steel bar, and requires separate equipment at the factory or the site by using binding means such as bolts and nuts. It is aimed at shortening the air with the reduction of the work force as well as the convenience of the work because the on-site workers easily and quickly fasten the various members by assembling various members.
