摘要:
The invention relates to an arrangement in plant equipment for directly supplying to a building element a binder comprising, for example, mortar of pumpable consistency and containing water. The plant equipment includes a vessel for ready-mixed binder, a motor-driven pump and a pump conduit (3) for supplying binder under pressure to a nozzle (4). In order to prevent liquid from being expelled from the binder when the pump is stopped, so as to leave a dry plug in the nozzle, means (18) are provided for maintaining the pressure in and adjacent the nozzle (4) at a level which coincides at least substantially to atmospheric pressure.

A piping nozzle for applying jointing material in the construction of masonry walls or facades includes a housing having an outlet (12) for jointing material which is introduced under pressure into the housing interior through an inlet (19). In accordance with the invention there is arranged in the housing interior an inlet means (20) which is connected to the inlet and which presents a slot (21) which faces away from the outlet (12); and a dividing means (22) adapted to divide the jointing material exiting through the slot into two flows, which are guided towards the outlet opening for the purpose of mixing the jointing material.

In a building block of the kind which presents at one end thereof a recess (17) for accommodating the jointing material of a heading joint (16) the recess is so formed that a first wall portion (18) thereof creates a greater pressure drop in pipeable jointing material forced under pressure into the recess than the drop in pressure created by a second wall portion (19) of the recess.

The invention relates to an arrangment in containers (1) intended to hold materials of a pumpable consistency. The arrangement comprises a reversible motor (9) which is drivably connected to a rotatable agitator (12) located in the container (1). The arrangement is characterized in that there is arranged between the agitator (12) and the pump (2) a coupling means (11) adapted to couple the agitator to the pump when the agitator is driven in a frist rotational direction, and to hold the agitator disengaged from the pump when the agitator is driven in a second rotational direction, opposite to the first.
