Referring to FIGS. 1 to 6 , the earthquake-resistant window and door steel frame 1 according to the first embodiment of the present invention may be installed in a hole H of a building where a window is installed.

At this time, the earthquake-resistant window steel frame 1 is formed of an earthquake-resistant material and installed in a structure that can withstand external forces, and serves to reinforce the windows installed on the inner circumferential surface of the earthquake-resistant window steel frame 1. .

The earthquake-resistant window steel frame 1 may be divided into an internal type or an external type according to the location where the base plate 10 to be described later is installed relative to the hole H in which the window is installed.

At this time, the position where the H-beam 31 is coupled to the base plate 10 may be different according to the position where the base plate 10 is installed in the inner type and the outer type.

The internal type may be a case where the base plate 10 is installed on the inner circumferential surface of the hole H, and the external type may be a case where the base plate 10 is installed around the hole H.

The window steel frame 1 is provided in a rectangular shape, but since this is only an embodiment, it is not limited thereto and may be provided in a polygonal shape such as a triangle or a pentagon.

The earthquake-resistant window steel frame 1 may include a base plate 10, a stiffener 20, and a frame 30.

More specifically, the window steel frame 1 is a space where the frame 30 is coupled to the exposed surface of the base plate 10 installed in an internal or external type, and the base plate 10 and the frame 30 are coupled The stiffener 20 may be provided and bonded to the form.

The base plate 10 may be installed as an internal or external type.

The base plate 10 is preferably in the form of a flat rectangle having a predetermined length and thickness, but is not limited thereto.

The base plate 10 may include a coupling material 11 and a coupling hole 12 .

The base plate 10 may be fixedly coupled by a coupling material 11 when installed in an internal or external type.

At this time, the coupling material 11 is preferably composed of bolts, but since this is only an embodiment, it is not limited and may be composed of various materials such as nails and rivets.

The coupling material 11 passes through the coupling hole 12 and is coupled to the installation position, thereby fixing the base plate 10 .

The coupling hole 12 may be provided in plurality in a configuration formed in the base plate 10 .

The coupling holes 12 are preferably formed at regular intervals in the base plate 10, but are not limited thereto.

The stiffener 20 may be formed on an exposed surface of the base plate 10 or an exposed surface of an H-beam 31 to be described later to reinforce durability of the frame 30 .

When the stiffener 20 is formed on the base plate 10, the stiffener 20 may be selectively formed instead of being formed on all exposed surfaces of the base plate 10.

For example, as shown in FIG. 6, when the earthquake-resistant window steel frame 1 is an internal type, it can be confirmed that the stiffeners 20 are formed only on the upper and lower base plates 10, but are not limited thereto , It may be formed on part or all of the base plate 10 according to the needs of a person skilled in the art.

Referring to FIG. 7 , when the stiffeners 20 are formed on the exposed surface of the base plate 10, different numbers may be provided depending on the central portion and both ends of the base plate 10.

For example, one stiffener 20 may be provided at the central portion of the base plate 10 and two or more at both ends thereof.

This allows a minimum of stiffeners 20 to be located in the center portion of the H-beam 31 coupled to the base plate 10 that is relatively resistant to external force, and a plurality of stiffeners 20 to be located at both ends of the H-beam 31 that is vulnerable to external force. This is to effectively reinforce seismic resistance while minimizing the use of raw materials.

The frame 30 preferably forms a quadrangle along the shape of the hole H, but since this is only an example, it is not limited thereto and may be variously changed according to the shape of the window or hole H, such as a polygon.

The frame 30 may be combined with the base plate 10 .

At this time, it is preferable that both ends of the H-beams 31 are cut in a diagonal shape according to the shape of the frame 30 so that the plurality of H-beams 31 can completely come into contact with each other. This is because both ends of the H-beams 31 are not cut and are vulnerable to external force when the H-beams 31 are separated and coupled using only the corner portion 32.

However, it is not limited to this, and the plurality of H-beams 31 can be connected and coupled through the corner portion 32 in the space created between the H-beams 31 because the plurality of H-beams 31 do not completely contact each other.

Accordingly, the frame 30 can be transported in a separated state rather than a combined state of the plurality of H-beams 31 and the corner portion 32, so that it can be transported more easily and can be easily transported even in a narrow space. There are advantages.

The H-beam 31 has a predetermined length and may come into contact with the stiffener 20 when combined with the base plate 10.

For example, when a plurality of H-beams 31 are arranged in a rectangular shape, it is preferable that the corner portion 32 be 'L'-shaped. However, this is only an example for illustrative purposes and is not limited thereto.

The corner material 33 is installed at a portion where a plurality of H-beams 31 are connected by the corner portion 32 to increase the fixing force.

At this time, the corner material 33 is preferably a triangular shape, but is not limited thereto, and may be variously changed depending on the shape of the portion connected by the corner portion 32.

In addition, a plurality of corner materials 33 may be installed, but not limited thereto, and only one may be formed or may be installed in different numbers at portions connected by the corner portion 32.

Referring to FIGS. 9 to 13 , the base plate 10 may include a plurality of fixing protrusions 13 , and the H-beam 31 may include a section hole 311 and a fixing part 312 .

The fixing protrusion 13 may protrude in a direction coupled to the H-beam 31 through the beam hole 311 and have a predetermined length.
