A tool for the installation of building elements into a compartment of a wall or planar support comprises a frame (2, 102) with a central passage (3, 103) adapted to be placed in correspondence of the compartment (V) for introducing thereinto the building element (E), which frame (2, 102) comprises two longitudinal bars (4, 5; 104, 105) having respective retaining surfaces (6, 7; 106, 107) reciprocally facing and transversally spaced with a first transverse distance (di) to define the passage (3, 103) and first means (8, 108) for adjusting the first transverse distance (di) adapted to allow the facing retaining surfaces (6, 7; 106, 107) to removably engage opposite faces (F, F') of the building element (E) and to temporarily support it during its installation. The first adjustment means (8, 108) comprise a pair of connecting elements (9, 10; 109, 110) substantially elongated along respective first transverse directions (Y, Y') and longitudinally spaced with each other to delimit laterally the passage (3, 103). Each connecting element (9, 10; 109, 110) is adapted to connect respective opposite longitudinal ends (4', 5'; 4", 5"; 104', 105'; 104", 105") of the bars (4, 5; 104, 105) and has an intermediate section (11, 12; 111, 112) interposed between the bars (4, 5; 104, 105) with an adjustable transverse length (y, y') to adapt the first transverse distance (di) to the maximum transverse dimension (D) of the building element (E). |
