Description

Reinforcement support structure {Support for a upper reinforcing bar of footings}

The present invention relates to a reinforcing bar support structure, and more specifically, to a reinforcing bar support structure, which is installed on the upper part of the foundation ground to prevent sagging of the foundation bars while controlling the height at which the foundation bars are installed, and to allow field workers to work safely on top of the foundation. It relates to a reinforcing bar support structure used to support the foundation bars.

Generally, foundation construction for building construction involves installing lower foundation bars and upper foundation rebars. Recently, as high-rise buildings have become common and the depth of foundations has deepened, upper foundation rebars are installed higher from the abandoned concrete layer poured on top of the foundation ground. And the amount of reinforcement required for foundation construction also increased. Therefore, it was required to install a reinforcing bar support structure that safely supports the foundation bars while preventing deflection of the foundation bars and easily adjusting the height at which the foundation bars are installed.

Conventionally, in cases where the foundation thickness is less than 2.5m, a hat-shaped bar chair called 'Uma' is widely used in sites where the reinforcement bars are manufactured in a 'ㄷ' shape to support the upper foundation reinforcement bars. The reinforcing bar support structure to support the upper foundation is not only difficult to secure structural stability because its height is not adjustable, but it is also installed in a form that is vulnerable to buckling due to the upper load, so it must be installed at narrow installation intervals to prevent buckling, making it economically unfeasible. There was a problem with it falling and the air getting longer.

In order to improve this problem, the present applicant applied for and registered a reinforcing bar support structure under Korean Patent Registration No. 10-2218166. The selected name is a vertical structure consisting of a vertical member and a plurality of horizontal members, and a reinforcing bar height adjusting part that supports and supports the upper foundation bar while adjusting the height of the connecting support member by directly welding a reinforcing bar height adjustment rod to the upper end of the vertical member. It is composed.

However, in this selection, the rebar height adjustment rod is welded and fixed to the top of the vertical member, increasing the number of parts, the welding length of the rebar height adjustment rod that transmits the upper load to the vertical member is long, increasing the production cost, and the external force applied to the rebar height adjustment rod from outside. Since it is solely responsible for, a structure to share these external forces is required. In addition, it is manufactured by installing threads on two rebar height adjustment rods and inserting a height adjustment nut inside, and the height must be adjusted by turning the nuts at the installation site, so it takes a lot of work time and the threads may be damaged during the manufacturing and installation process. There was also a problem of not being able to use the rebar support structure. In addition, the rebar stand support part installed to support the rebar stand had a complicated manufacturing process because the member was large and had to be manufactured by welding two mounts inside the support frame. In addition, because the gap between the two 'ㄱ' shaped mounting brackets that face each other and are welded inside the support frame is fixed, there was a problem of difficult construction when inserting two long rebar holders into the mounting brackets.
