Abstract
Abstract A building structure is provided for the recurrent detonation of explosive charges of up to several hundred kg with the aim of obtaining effective sound damping and economical use of materials. The building comprises a tube shaped steel structure (2) which with two gable walls (4, 4) inside the tube, defines a detonation chamber (6) in the centre portion thereof. One or preferably both of the gable walls are apertured by a plurality of openings therethrough. A webbed wall or the like (20) is situated at least in one end portion of the tube which together with the respective adjacent gable wall (4) a gable chamber (16) which is filled with a mass of stones (18) or the like. The tube shaped steel structure is positioned horizontally and freely rests 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 damped gas discharge and pressure relief.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
116 words
A building for the recurrent detonation of explosive charges, comprising a tube shaped steel structure which, together with two gable walls defines a detonation chamber in the centre portion thereof, one or both of said gable walls being apertured by a plurality of openings therethrough, and a webbed wall or the like at least in one end portion of the tube which together with respective adjacent gable wall defines at least one gable chamber, said building being effective to obtain a sound damped gas discharge and pressure relief, said tube shaped steel structure being positioned horizontally and freely resting on a sand bed and being covered along the entire length of the tube construction with sand.
Claim 2
Dependent Claim
116 words
A building for the recurrent detonation of explosive charges, comprising a tube shaped steel structure which, together with two gable walls defines a detonation chamber in the centre portion thereof, one or both of said gable walls being apertured by a plurality of openings therethrough, and a webbed wall or the like at least in one end portion of the tube which together with respective adjacent gable wall defines at least one gable chamber, said building being effective to obtain a sound damped gas discharge and pressure relief, said tube shaped steel structure being positioned horizontally and freely resting on a sand bed and being covered along the entire length of the tube construction with sand.
Claim 3
Dependent Claim
16 words
A building according to claim 1, wherein the or each gable chamber is filled with stones.
Claim 4
Dependent Claim
38 words
A building as claimed in claim 1, wherein both gable walls are apertured with a plurality of openings therethrough, and in each end portion of the steel tube there is mounted a webbed wall and a stone filling.
Claim 5
Dependent Claim
37 words
4, A building as claimed in claim 3, wherein the internal gable walls are made by the welding together of wide flanged steel beams positioned side by side and anchored to the inside of the tube structure.
Claim 6
Dependent Claim
16 words
A building as claimed in claim 4, wherein the said anchoring is by means of welding.
Claim 7
Dependent Claim
75 words
A building as claimed in claim 4 or 5, wherein the flanged parts of the steel sections facing the detonation chamber are provided with apertures therethrough in order to obtain a strongly choked discharge of explosion gases, and the gable wall surfaces facing the gable chamber are provided with openings the total area of which substantially correspond to the total free area existing between the stones in the stone mass positioned in the gable chamber.
Claim 8
Dependent Claim
15 words
A building as claimed in claim 6, wherein the gable wall surface openings are slits.
Claim 9
Dependent Claim
56 words
A building as claimed in claim 7, wherein the tube shaped steel structure is cylindrical and is designed, as regards strength, on the basis of the need to be able to sustain the tensile stresses arising from the prevailing gas pressure as well as the supplemental stresses and strains arising from possible impact by detonation fragments.
Claim 10
Dependent Claim
48 words
A building as claimed in any preceding claim, wherein an access tunnel is provided through one of the gable chambers and has an inwardly movable pressure proof steel door facing the detonation chamber, the door being a hollow door and being filled with a sound absorbent material. .
Claim 11
Dependent Claim
14 words
A building as claimed in claim 9, wherein the sound absorbent material is sand.
Claim 12
Dependent Claim
31 words
A building as claimed in claim 9 or 10, wherein there is arranged a ventilation duct including a shock valve and a fan which is positioned at the outer gable wall.
Claim 13
Dependent Claim
25 words
A building as claimed in claim 11, wherein the ventilation duct is provided in that gable wall which is not provided with the access door.
Claim 14
Dependent Claim
55 words
A building as claimed in any preceding claim, wherein the tube shaped steel structure is provided externally at each end with a lateral buffer plate structure the size of which generally corresponds to the natural angle of repose of the sand covering, thus enabling full sand covering along the entire length of the steel structure.
Claim 15
Dependent Claim
45 words
A building as claimed in any preceding claim, and which is designed to be used for metal working purposes using heavy plating and large quantities of explosives, wherein a trolley crane unit is installed for the transport of materials into and out of the building.
Claim 16
Dependent Claim
46 words
A building as claimed in claim 14, which is so adapted that detonation of the explosive charge takes place downwardly against a plate object which is to be worked, which object is positioned on a sand bed or the like specially adapted for such work operations.
