BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket structure and a construction method thereof, and more particularly, to a bracket structure and a construction method thereof that improve a bracket structure to save installation cost, reduce installation work time, and increase bearing capacity.

Generally, brackets are widely used to support a precast panel, a slab, or a beam in a wall or a column of a high-strength multi-layer tunnel, a vertical tunnel, or a high-rise building formed of a reinforced concrete structure.

For example, Korean Utility Model Registration No. 20-383309 entitled " Formwork for slab construction of a basement layer to which a slurry wall is applied " (see Figs. 6a, 6b and 6c) is disclosed as an example. This prior art is a work structure for constructing a slab of a basement layer to which a slurry wall 100 is applied. The slab wall has a T-shaped planar structure in which a transverse member 116 and a longitudinal member 118 are integrally joined, A bracket 110 to which the transverse member is fixedly installed at side angular positions; A support girder (120) having an end fixed to a longitudinal member of the bracket and directly fixed to a side surface of the slurry wall via the bracket; First auxiliary supporting means fixed horizontally long horizontally along the slurry wall by horizontally arranging the two adjacent brackets at the same height as the supporting girder and fixing both ends of the brackets to the lateral members of the bracket; And a deck plate (140) installed on the supporting girder and the first auxiliary supporting means so that the concrete can be installed and cured on the deck plate to enable the construction of the slab directly connected to the slurry wall (Refer to claim 1) for constructing a slab of a basement layer to which a slurry wall is applied.

However, since the lateral member 116 of the conventional bracket 110 is installed directly on the non-shrinking grout 112, there is a problem that the supporting force against a large load is insufficient.

The anchor for fixing the lateral member 116 of the bracket 110 to the slurry wall 100 may be a chemical anchor or a set anchor 114 or a reinforcing anchor 117 previously embedded in concrete, The chemical anchor or the set anchor 114 may interfere with the inner reinforcement during the process of forming the anchor attachment hole, and the installation time is long. In particular, the chemical anchor is expensive. Also, even when the reinforcement anchor 117 is buried in advance, the transverse member 116 is welded to the reinforcing anchor 117 and the longitudinal member 118 is welded to the transverse member 116, The manufacturing process is complicated and the cost is increased, and a lot of welding may cause structural problems.

Further, in the case of the transverse member 116 coupled to the anchor or anchor, exposure to the outside of the slurry wall 100 results in a bad appearance and interferes with other members.

The longitudinal member 118 is welded to the transverse member 116 in the field so that it can adversely affect the slurry wall 100 due to the high heat caused by welding, There is a problem.
