The bottom of the sand bag 540 is reinforced by a circular leather operation with a diameter of about 150 mm, and a ring bolt having a diameter of about 5 mm can be attached to the center by piercing a hole in the center. The opening part of the apex can be reinforced with leather pieces or the like and can be tightened with a hose band or the like like the bottom surface.

The sand filled in the sand bag 540 may have a volume specific gravity of about 1500 kg / m 3, passing through a sieve of 2 mm and remaining in a sieve of 0.6 mm.

The dropping device 550 includes a plurality of fixed frames 551 disposed below the ends of the drop units 520 and a plurality of open / close protrusions 552 opened / closed between the plurality of fixed frames 551, And a control knob 553 for controlling the opening and closing protrusion 552. [

The fixed frame 551 is formed at a predetermined height from the end of the drop unit 520 and the sand bag 540 so that the drop wire 512 to which the sand bag 540 is attached is inserted between the fixed frames 551 So that it can be accepted.

The opening / closing protrusion 552 is formed between the plurality of the fixed frames 551 and can be opened / closed laterally by a separate operation. The falling wire 512 can be caught by the dropping device 550 by the opening and closing protrusion 552 and the opening and closing protrusion 552 is provided at the end of the dropping wire 512 when the opening and closing protrusion 552 is opened by the fixing frame 551 The impact resistance test can be performed while the sand bag 540 is lowered.

The control knob 553 may be turned by a knob or a separate switch may be provided to control the opening / closing protrusion 552.

When the impact resistance test of the door set 20 is performed using the impact resistance testing apparatus 500, after confirming that the door 21 of the door set 20 is normally operated, the door 21 is moved to the door frame 22 ), The test may be carried out.

8, after the sand bag 540 has confirmed in advance a predetermined position to impact the door 21, the sand bag 540 is hooked on the drop device 550 The predetermined angle can be adjusted through the drop cylinder 530. At this time, when the sand bag 540 is hooked to the drop device 550, a separate hook may be provided to hang the drop wire 512 with the sand bag 540 to the drop device 550.

The falling part 520 to which the sand bag 540 is caught is operated so that the drop wire 512 is not bent and the sand bag 540 is operated by the pivotal movement of the door 21 So that a shock is applied to a predetermined position. At this time, the sandbag 540 may be protruded so that the second impact is not applied.

After the impact resistance test on the door set 20 is completed, the sand bag 540 is hooked to the drop unit 520, and the presence or absence of the concave, cracked, peeled, . In order to check the opening and closing of the door frame 22 and the door 21, the door 21 may be coupled to the door frame 22 to check for anomalies.

The impact resistance test is repeatedly performed and the state of the door set 20 can be grasped.

Although the door set testing apparatus according to the embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments shown in this specification. Those skilled in the art, who understands the spirit of the present invention, can readily suggest other embodiments by adding, changing, deleting, adding, or the like of components within the scope of the same idea, I would say.
