I-beam bracket

technical field

The utility model relates to the field of construction equipment, in particular to an I-shaped steel fixing frame.

Background technique

When pouring concrete for the wall on the construction site, it is necessary to bury the steel in the concrete to increase the strength of the wall, which is safe to use and has a long service life.

Before pouring the concrete, the steel must be fixed in the set position, so a steel fixing frame is required. Most of the existing fixing frames for installing steel are to adopt inverted U-shaped anchor rings. The inverted U-shaped anchor rings are fixed on the set position with concrete, and the U-shaped opening direction is towards the bottom surface of the body of wall. After the anchor rings are fixed, the steel is clamped between the anchor rings. In order to make the clamping effect better, the plate is filled in the gap between the anchor rings and the steel.

The inventor found in the research that when the existing concrete is poured, the installation of steel has at least the following disadvantages:

First, when the existing steel fixing frame is installed, errors are prone to occur, which in turn affects the installation of the steel; second, the existing fixing frame needs to be filled with plates to fix the steel, and the fixing effect is poor. During the pouring process, the position of the steel Changes occur, which affect the pouring quality; three, the existing fixing frame is pre-embedded in the body of wall, which cannot be reused, and the utilization rate of the material is low.
