This utility model provides a detachable elevator shaft fall arrestor for building construction, belonging to the field of building construction technology. It includes an installation frame with an installation groove at the top. A support plate is slidably installed in the installation groove, and an extension component is provided on the support plate. The extension component includes a first extension plate, with first extension plates on both sides of the support plate. A through groove is provided at one end of each of the two sets of first extension plates, and a second extension plate is provided at the bottom of the first extension plate corresponding to the through groove. A third extension plate is provided between the two sets of second extension plates. Two sets of grooves are provided at the bottom of the support plate corresponding to the installation frame, and a pressure sensor and a buzzer are respectively installed in the two sets of grooves. This device expands the protection range through the extension component and uses the pressure sensor and buzzer to monitor and alarm personnel movement, improving safety protection capabilities and solving the problem that traditional elevator shaft fall arrestors in the prior art have fixed dimensions and lack effective warning functions.
