A supporter for construction is provided to fix a first pipe to a second pipe by inserting a tapered internal stopper in a tapered external stopper. A supporter for construction comprises a first pipe(10), a second pipe(20), an external stopper(30), and an internal stopper(40). The second pipe is smaller than the first pipe in a diameter. The external stopper is installed at one end of the first pipe by sliding and has a hollow communicating with a hollow of the first pipe. The internal stopper is installed at one end of the second pipe. The outer periphery of the internal stopper contacts with the inner periphery of the external stopper, when the internal stopper is inserted in the hollow of the first stopper. The outer periphery of the internal stopper and the inner periphery of the external stopper are tapered down along an insertion direction. The internal stopper fastens the second pipe to fix, as the internal stopper inserted into the external stopper.
