A building structure for recurrent detonation of explosive charges of up to several hundreds of kilos with the aim to obtain effective sound dampening and economical use of materials. The building comprises a tube shaped steel structure (2) with two gable walls (4,4) inside the tube and which defines an explosion chamber (6) in the center portion thereof. One or preferably both of said two gable walls are apertured by a plurality of through-going openings. A webbed wall or the like (20) is situated at least in one end portion of the tube which together with respective adjacent gable wall (4) defines one, respectively two, gable chambers (16) which are filled with a mass of stones (18) or the like. The tube shaped steel structure is positioned horizontally and freely resting on a sand bed (36) or the like and is covered along its entire length with sand (38). The building is effective to obtain a sound dampened gas discharge and a pressure relief.
A building structure for recurrent detonation of explosive charges of up to several hundreds of kilos with the aim to obtain effective sound dampening and economical use of materials,
A building as claimed in any of the preceding claims, characterized therein that the tube structure externally at each end is provided with a lateral buffer plate structure (40) the size of which generally corresponds to the natural fall angle of the sand covering thus enabling full sand covering along the entire length of the steel structure.
A building as claimed in any of the preceding claims and which is specially designed to be used for metal working purposes using heavy plating and large quantities of explosives, characterized therein that a trolley crane unit (28, 29) is installed for the transport of materials into and out of the building.
