Description

Window construction reclamation encavolts

The present invention relates to a window construction embedded anchor bolt, and more specifically, to a window construction embedded anchor bolt that can accurately install an anchor bolt in a concrete structure and also provide a neat finish.

A common method for attaching or fixing a facility to a concrete structure is to drill a hole at a specified location in the completed concrete structure, install a set anchor or chemical anchor to fix it, and then assemble it with bolts along with the facility.

The above method has the problem that since holes for anchor insertion must be formed in the concrete structure after the concrete structure is completed, it damages the concrete structure, and when drilling, interference occurs with reinforcing bars placed near the concrete surface, which damages the reinforcing bars or makes it impossible to drill at the desired location, and the penetration depth of the anchor is not constant and may become small depending on interference with the reinforcing bars, which reduces the allowable capacity of the anchor.

As a prior art for solving the above problem, a built-in anchor and an installation method thereof were disclosed in Korean Patent Publication No. 10-2010-0037696. This prior art is a built-in anchor constructed to hang a facility in a concrete structure, wherein a steel bar having a polygonal or circular cross-section and a constant length serves as a connecting nut, and a bolt hole having a thread formed in the longitudinal direction of the connecting nut so as to be able to fix an attachment is formed at the inner side of one end of the connecting nut, and an anchor bolt is formed at the other end of the connecting nut, so as to provide an anchor-type nut in which the connecting nut and the anchor bolt are integrated, so that when the anchor-type nut is embedded in a concrete structure, the attachment can be fixed with a fixing bolt at the attachment-type connecting portion.

However, the above-mentioned conventional technology has a problem in that since only one side of the anchor is connected to the formwork, there is a possibility that the other side may sag or tilt, and thus the anchor cannot be installed accurately horizontally.

Therefore, there is an urgent need to develop technology to accurately install landfill anchors.

Republic of Korea Patent Publication No. 10-2010-0037696
