Description

Technical Field

[0001] The present invention relates to the technical field of fire door measurement, and in particular to a device and method for measuring deformation of a fire door. Background Art

[0002] A fire door is a type of door. Usually, a fire door needs to have good fire resistance and be able to have a flame retardant effect. It also needs to have a high-strength fireproof effect. When a fire door is in use, it can be installed on the designated door frame.

[0003] The disadvantage of the prior art is that when a fire occurs, after the fire door is closed, it will be burned at high temperature for a long time, and the surface temperature of the steel plate on the fire side of the fire door will become very high (the temperature in the furnace is 945°C in 1 hour and about 1000°C in 1.5 hours). Since the fire door is locked by the door lock and hinge, the accumulation of the fire door due to heat expansion will be squeezed toward the four corners of the fire door, thereby causing expansion deformation and causing the upper and lower corners of the locked side of the fire door to deform and form a large gap. Therefore, a fire door deformation measurement device and method are now needed. Summary of the invention

The left and right groups of side force plates 29 and the upper and lower groups of top force plates 30 directly clamp the fire door 33. The side force plates 29 and the top force plates 30 cooperate to limit the sides of the fire door 33, thereby completing the acquisition of the side data of the fire door 33 during the test of the fire door 33.

After the fire door 33 is placed inside the fire door measurement assembly, the second electric push rod 24 is used to control each group of clamping frames 26 and the height limiting plate 27 to be tightened to complete the positioning of the fire door 33, ensuring that each group of side force plates 29 and top force plates 30 can fit the side of the fire door 33. Secondly, the multiple groups of measurement plates 23 set on the front side of the mounting plate 19 fit the outer surface of the fire door 33.
