Abstract: A cooling ceiling for interior air conditioning having a pipe system through which cooling air flows is arranged at least in part between the ceiling (1; 101) of a building and corresponding ceiling elements (3; 103) and is secured in the mounted position by a holding member (5; 105) which carries the ceiling elements (3; 103). In the mounted position, the cooling pipe (4; 104) lies against the ceiling elements (3; 103). A joint (10, 10', 10"; 111, 111', 111") arranged between the holding member (5; 105) and the corresponding area of the cooling pipe (4; 104) has a depression (9, 9'; 109) for receiving the cooling pipe (4; 104) and supports said cooling pipe on the holding member (5; 105) in a vertically adjustable manner.

Abstract: A jointing clamp for pressing pipe connections, particularly for pipes of composite materials, includes two pressure clamps, each of which carries a form part of a form insert and which are connected with one another by connecting plates that are disposed on either side, and which are supported at the connecting plates so that they are can be pivoted in opposite directions about parallel pivoting axes and can be moved into the closed position by means of a clamp driving device which can be connected to the jointing clamp by means of a crossbolt reaching through aligned boreholes in the connecting plates. In order to achieve a pressed pipe connection of high form accuracy, the form insert is constructed in three parts and the third form part is supported in a stationary manner between the connecting plates of the jointing clamp.
