Description

TECHNICAL AREA

The present disclosure relates to a module for constructing a splinter protection cage for systems at risk of explosion and test structures that can have an explosive effect or are to be protected against the effects of explosions, in particular for gas storage tanks.

TECHNICAL BACKGROUND

Fragmentation protection cages are used in a wide variety of scenarios and relate to both work and property protection. In particular, the application relates to protection against a pressure wave caused by an explosion and flying fragments, which can emanate from a potentially explosive gas storage/tank system, in particular during the operational safety test of pressure vessels. However, such superstructures can also be used to secure gas filling stations. However, the subject matter of the application potentially also relates to protection against unintentional or willful damage to industrial plants, infrastructure objects and military objects by an explosion and thus also to countering terrorism.

So far, the splinter trap has been designed using rigid structural measures such as massive reinforced concrete walls in connection with earthen walls. Related solutions are less focused on splinter protection, but typically on bullet protection and/or privacy protection, such as U.S. 2017 063 054 A-A and EP 2 975 198 A1 . However, the contact surface of such a device for the pressure waves to be considered here is too large, so that such structures would not withstand the expected load and would probably fall over simply from a pressure wave. A much more robust and stable construction, which, however, can only withstand a pressure wave to a limited extent and does not weaken it, but rather deflects it upwards as an explosion protection wall CN 202 990 152 U disclosed. Even the misappropriated use of inexpensive building blocks and insulating walls intended for flood protection NL 1 023 479 C2 would lead to a pressure build-up that might overtax the stability of the wall and lead to possible fragments being diverted primarily upwards, which would result in a larger fragment flight radius.

Previously known solutions are therefore typically structurally complex, inflexible and expensive or completely unsuitable for the intended purpose. Against this background a technical task of reliably intercepting high-energy fragments and dampening a possible blast wave without losing or massively damaging the protective structure. The sought-after splinter protection cage should be adjustable in its dimensions, closed at the corners, easy to erect, but also easy to dismantle.

SUMMARY OF THE INVENTION

According to the present disclosure, a system building block according to claim 1 is provided. A splinter protection cage constructed from this, proposed according to claim 12, comprises a large number of such system modules, which are offset to one another according to a desired expansion in the form of a cage which can be covered at the top by other measures - such as stone chip protection nets - stacked on top of one another with an essentially rectangular base area are. The stability and stability, fluid permeability, numerous options for staggered stacking and the relatively easy assembly and disassembly of achievable splinter protection walls and splinter protection cages meet the requirements described at the beginning.

Embodiments and aspects of the invention make it possible to provide a fragmentation protection wall or cage in a novel, simple, fast and economical manner. Structures of this type are suitable for use on a test field to protect personnel and peripherally arranged measuring devices, reduce the protection or blocking radius in the vicinity of the relevant systems, any tanks and tank farms, in particular gas tanks, but also for the protection of Infrastructure objects and other facilities against external attacks, especially against a bomb attack.

GENERAL ASPECTS OF THE INVENTION

Some further aspects of the invention are described below. Unless explicitly stated otherwise, these aspects are independent of each other and can be combined with each other in any way, as far as technically possible and reasonable. For example, any aspect described in this disclosure may be combined with any other aspect or embodiment described herein to yield further aspects or embodiments.

According to one embodiment, the system module for constructing a splinter protection wall can have a rectangular footprint provided with recesses, two opposing fluid-permeable rectangular side surfaces aligned perpendicularly to the footprint, and a top surface provided with knobs, with the knobs being dimensioned and arranged to correspond to the recesses, so that several System building blocks can be stacked in an association to form a fluid-permeable wall or a fluid-permeable cage comprising interconnected walls. In this context, a bond is understood to be an arrangement of system building blocks that are offset from one another and which, in analogy to brick masonry, for example, have a middle stretcher bond or a trailing stretcher bond or, for example, a block bond, a Brandenburg bond, a Flemish bond or a Gothic bond form.

Advantageously, a splinter protection wall constructed from a large number of system building blocks is sufficiently fluid-permeable, ie it weakens a pressure wave and is able to reliably intercept any fragments and splinters of a burst pressure vessel.

According to one exemplary embodiment, the nubs of two system building blocks aligned on all sides form an engagement of the nubs on the upper side of a lower system building block in the recesses on the underside of an upper system building block.

This advantageously increases the stability of a splinter protection wall and considerably facilitates the assembly of a splinter protection cage.

According to one exemplary embodiment, a first longitudinal extent of a base area of the knobs is essentially equal to a second longitudinal extent of the base area of the knobs, which is oriented orthogonally to the first longitudinal extent. “Essentially the same” is understood here to mean an identity taking into account the manufacturing tolerances customary in the process. In other words, the bases of the knobs can be inscribed in contours of identical squares or circles. The knobs and the corresponding engagement surfaces (knob receptacles) preferably have a square base.

The form fit achieved increases the stability of an erected splinter protection wall or splinter protection cage.

According to one embodiment, a ratio of a length to a width of a rectangular footprint and a ratio of the length of the rectangular footprint to a height of the side walls of the proposed system building block corresponds to a numerical ratio of 2:1 of the system building block essentially in the ratio of 2 : 1 : 1.

This advantageously results in a good fit with conventional concrete blocks of comparable external contours.

According to one embodiment, the number of recesses and knobs is even and preferably selected from 4, 6, 8, 10, or 2x2, 3x2, 4x2, 5x2, with the recesses in two rows along the rectangular footprint and the knobs in two corresponding rows are arranged along the top surface.

The system building block thus follows the construction principle of Lego building blocks and makes it possible to achieve a comparable variety of possible structures.

According to one embodiment, the knobs are set back from an outer edge of the top surface.

This results in larger lateral web widths for the compatible dimensioned recesses arranged correspondingly on the footprint, which reduces damage when installing splinter protection walls.

According to one embodiment, the number of recesses and the number of knobs is 8.

According to one exemplary embodiment, the proposed system building block is directly compatible and/or stackable with a concrete building block provided with knobs and recesses that correspond to one another according to the Lego principle.

There is advantageously a great deal of design freedom in the contouring of an explosion protection cage.

According to one exemplary embodiment, the two fluid-permeable side walls lying opposite one another are formed by mutually spaced end faces of hollow profiles arranged parallel to one another.

For example, the cross section that is always the same when using identical hollow profiles ensures the formation of a honeycomb structure and high stability of the system building blocks against lateral loads with optimal production, for example compared to tubes with a circular profile. However, tubes (circular cross-sections) are also suitable in principle, the formation of a honeycomb-like structure being achieved is essential.

According to one embodiment, the hollow sections are rectangular hollow sections. They are spaced apart from one another in layers separated from one another by intermediate floors and are offset relative to one another in relation to adjacent layers and are welded at least in sections to the intermediate floors. The side walls are thus formed by rectangular hollow profiles stacked in layers, individual layers being additionally separated from one another by intermediate floors.

Advantageously, this increases the flexibility in the choice of suitable semi-finished products, the stability of the system building blocks and structures built using them. Likewise, hollow profiles that are adjacent to one another can also be connected directly to one another and can therefore be used without intermediate floors.

According to one embodiment, the system module exclusively comprises a material that is corrosion-resistant or at least superficially made corrosion-resistant, for example a polymer, or comprises a metal provided with a corrosion-resistant protective coating that is selected from aluminum and steel or from an aluminum, titanium and steel alloy. Polymer materials can also be welded together (joined with a material bond). Likewise, from a polymer, For example, by extrusion, manufactured hollow profile pieces are glued together or with intermediate floors.

The measures described advantageously enable a reduction in costs.

According to one exemplary embodiment, the hollow sections are hollow steel sections and the intermediate floors are sheet steel, with the hollow steel sections being connected to the steel sheets by weld seams. In this case, the weld seams preferably run along the edges of the hollow profiles. To save costs, the hollow profiles can also be fastened only in sections by weld seams or spot-welded.

This results in increased stability. If the potential load is less severe, the weld seams can also be interrupted.

According to one embodiment, all surfaces of the system building block are hot-dip galvanized.

According to one embodiment, a splinter protection wall is proposed, which comprises a large number of system building blocks according to one of the embodiments described above, the large number of system building blocks being arranged one above the other as a stack (beam) or association and to one another in a row of system building blocks of directly adjacent system building blocks of the splinter protection wall removable fasteners can be connected. The releasable fasteners are selected from screws and nuts corresponding to the thread of the screws.

The beams described with the above embodiment, comprising system building blocks connected to one another by releasable connections (eg screw connections), can be used to cover a splinter protection cage which is initially open at the top. The profile channels formed by the hollow profiles of the beams described are typically rotated by 90° relative to the side walls of the enclosing splinter protection walls and are therefore aligned vertically open at the top. Several beams arranged next to one another can thus serve as cover elements, even spaced apart from one another, which now also close the splinter protection cage, which was initially open at the top in the form of a fence, at the top. The system building blocks of the side walls do not normally require any additional fasteners connecting them to one another. It can generally be assumed that the knobs engaging in corresponding recesses have a weight of about 500 kg per system building block and the offset in the assembly are sufficient to prevent neighboring system building blocks from shifting against each other, even in the event of extreme impulse loads. Advantageously, several splinter protection walls can be arranged adjacent to one another and, for example, at a right angle to one another with their side surfaces. For example, a splinter protection cage that is open at the top can be arranged around hazardous goods that are at risk of explosion, a gas storage facility that is at risk of explosion, a test installation that is at risk of explosion or around another type of industrial installation that is at risk of explosion. The upper opening of the initially open splinter protection cage, which corresponds in terms of area, for example to the fenced base area, can then be covered in a suitable manner with one or more layers of a coarse-meshed wire net, wire rope net or lattice fence or several of the beams described.

According to a further embodiment, a splinter protection cage is thus formed for shielding a gas storage device with a risk of explosion, dangerous goods with a risk of explosion, a test facility with a risk of explosion or another type of industrial plant with a risk of explosion. The resulting splinter protection cage comprises a large number, but at least four, splinter protection walls according to the embodiments described above and below, with the splinter protection cage typically completely enclosing the object at risk of explosion.

According to a variation of the system building block described at the outset, the uppermost system building blocks of the enclosing side walls of the splinter protection cage, which is closed at the top, do not have any knobs on their top surface, for example on the uppermost steel sheet, in order to ensure a stable support of the covering elements made up of system building blocks connected to form beams.

According to one exemplary embodiment, a splinter protection cage is thus proposed for shielding a gas storage device at risk of explosion, which includes a large number of the system components according to one of the aspects described above.

According to one exemplary embodiment, the plurality of system components are stacked on top of one another offset in relation to one another according to a desired extension of the splinter protection cage in the form of a structural body which is open at the top and has a base area which essentially follows a rectangular contour.

According to one exemplary embodiment, the splinter protection cage has a large number of corresponding concrete building blocks in addition to the large number of system building blocks. Suitable concrete building blocks are on opposite deck and floor surfaces with correspondingly dimensioned and arranged knobs according to a Lego principle and provided with recesses, the concrete building blocks forming a bond with the system building blocks.

According to a further exemplary embodiment, it is proposed to use the system modules described to construct a splinter protection wall that adjoins a potentially explosive system and/or to erect a splinter protection cage that surrounds a potentially explosive system. In this way, the surroundings of the potentially explosive system can advantageously be protected from damage and the risk to people who are in the vicinity of the potentially explosive system can be minimized. Such a splinter protection wall or a splinter protection cage encompassing it can be used, for example, to protect people and neighboring systems at and in the vicinity of hydrogen filling stations, pressure accumulators and liquid storage facilities, but also to protect storage facilities for other potentially explosive dangerous goods.

Accordingly, a hydrogen tank protection device is also proposed which comprises a splinter protection cage or at least one splinter protection wall, the splinter protection cage and the splinter protection wall comprising at least one system module according to one of the embodiments described above. The hydrogen tank can be a store or pressure store for gaseous hydrogen or a liquid hydrogen store (LH ₂ store).

Of course, the system modules can also be used to protect any test system or on a test field to protect personnel and peripherally arranged measuring devices.

A method for explosion protection proposed here accordingly includes the provision and largely complete arrangement of the designated system building blocks, forming a bond, for example a stretcher, truss, block or cross bond, which surrounds the potentially explosive system or separates it from neighboring areas.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention are explained in more detail below. The drawings serve to illustrate one or more examples of embodiments of the invention.

The proposed "splinter protection system modules" 10 correspond to the basic requirement of optimum protection for test personnel, passers-by and the environment (test equipment and building), for example during a pressure test of gas storage tanks with gas. A possible bursting of the test sample (e.g. a gas holder or a tank) as a result of overloading is assumed to be the worst, most serious event for the test.

The pressure wave that occurs during an explosion is diverted and slowed down (damping) in a targeted manner by a system of parallel hollow profiles 5 of the system module 10 or in the splinter protection wall constructed from them. Splinters of unforeseeable size and shape, which can arise when a gas storage tank bursts, are intercepted on the surface of a splinter protection wall constructed from a large number of the proposed system building blocks 10 or by a corresponding splinter protection cage 100 . If these are large (larger than an average diameter of the hollow profiles 5 used), they are braked completely. If they are comparatively small (smaller than an average diameter of the hollow profile 5 used), they are advantageously forced into an almost horizontal and thus short trajectory, if not slowed down or stopped entirely by collision with the walls of the hollow profile 5 used.

A significant aspect of the subject matter of the application, in addition to the explosion-protective effect, is the simple handling and compatibility of the splinter protection system building blocks 10 with conventional nub system building blocks 10' made of solid concrete. The proposed system building block 10 was adapted to a commercially available concrete system block system from the manufacturer BMG-Erfurt-Tiefthal (Bremer-Mohran), which includes stacking blocks 10' made of concrete. With the help of minor corrections, however, it can also be adapted to any other system of solid building blocks.

With the aim of ensuring maximum flexibility in the use of the proposed splinter protection system building blocks 10, a 2:1 format (2 rows each with 4 square knob fields) and a stone size of 100 cm x 50 cm x 50 cm is proposed. The dimensions of a length of the footprint of the system building blocks 10 of twice the width appears optimal for a quick practical application. Other system sizes such as 2x3 knobs or e.g. 2x6 knobs while retaining the square knob fields are easy to derive and can be manufactured just as easily if necessary.

Compatibility with conventional concrete building blocks 10' advantageously results in cost savings. Since the material alone of the proposed splinter protection system module 10 is significantly more expensive than concrete, it makes sense to use less expensive concrete elements for those areas of a splinter protection cage to be erected that are not primarily exposed to a pressure wave. This opens up numerous possibilities to set up a test and/or protective structure flexibly, quickly and inexpensively, advantageously without a foundation, and to be able to dismantle or implement it just as easily.

According to an embodiment, such as in 1 shown, the proposed system module 10 has steel construction hollow profiles 5 of 80×60 mm edge length and 8 mm wall thickness arranged offset to one another on steel sheets 6 (for example 15 mm thickness). Lateral flat steel bands (eg 15 mm thickness) can optionally be provided with recesses, for example with bores, for the use of additional fasteners. Of course, the system module 10 can also be produced by casting, 3D printing or the like; Steel hollow sections and flat steel are not the only materials to consider. Also, eg extruded, polymeric materials can be used. The base plate forming a footprint of the system (eg sheet steel, eg 15 mm thick) is provided with square recesses, the dimensions of which correspond to the external dimensions of knobs 3 arranged on a steel sheet (eg 15 mm thick) on top 4 of system building block 10 . The concept generally referred to here as the "Lego principle" of correspondingly arranged and correspondingly dimensioned nubs and recesses on two opposite surfaces (typically the bottom and top or the footprint and top surface) enables the system building blocks 10 to be stacked on top of one another without any problems and yet variably is comparable to brick masonry (stretcher, truss, block or cross bond). The preferred ratios of length x width x height of the edges of the proposed system building block of 2 x 1 x 1, or 1000 mm x 500 mm x 500 mm, allow great variability of possible associations of the system building blocks 10 for use as a splinter protection wall or their connection to one Fragmentation protection cage 100 (cf. 3 ).

As in 1 As can be seen, gaps between the adjacent hollow profiles 5 on the floor panel provided with the recesses can be stabilized by additional sheet steel plates. All connections of the hollow sections 5 and strips to the metal sheets 6 are welded connections. The semi-finished products used to construct a system module 10 can advantageously and cost-effectively be provided as blanks or flame-cut parts (hollow sections, flat steel, sheet steel, possibly slotted trapezoidal bodies for constructing the knobs, small sheet metal plates).

In 2 the exemplary configuration of a side face 2 of a proposed system module 10 is shown. In general, the number of intermediate layers (shown are 6 steel sheets 6 between the lower (perforated) sheet serving as a footprint and the upper sheet 4 carrying the nubs 3) corresponding to hollow profiles 5 used (42 are shown in each case) and the platelets used for reinforcement between the base plate and the plate arranged above it can also be reduced.

When testing gas storage tanks or using gas systems, there is either the intention of provoking a failure and, in principle, there is always a residual risk of failure, which can result in a pressure wave due to deflagration (hydrogen) or even flying fragments. Accordingly, it is necessary in many cases to use a splinter guard. In any case, the splinter protection reduces the cost of other protective measures such as a safety radius, etc. At high outlet pressures (H ₂ ) and/or high volumes, closed walls are only able to withstand the loads that occur with enormous effort. However, the concept proposed here of a system grid block 10 for erecting a splinter protection cage 100 is suitable for providing a splinter protection wall or a splinter protection cage 100 which withstands an expected pressure wave, while catching larger splinters and slowing down and directing smaller ones.

The invention focuses on the fact that the geometric structure of profiles 5 arranged parallel and offset to one another, which lead away from the source of pressure generation as directly and horizontally as possible, forces the pressure wave into "narrow channels" and thus dampens it if necessary. The arrangement of the canals in the Figures 1-3 each welded from 49 thick-walled, closed profile semi-finished products, leads to a robustness that is sufficient for the purposes mentioned, even with multiple loads. Here, not all splinters, but only the larger ones should be caught completely inside the splinter protection cage 100 and the smaller ones should be slowed down and steered on the way out by forced guidance in channels at least 400 mm long. This is done with the aim that even the smallest fragments could only fly a maximum of 100 m on their trajectory due to their forced horizontal launch alignment.

The concept of providing the proposed system building blocks 10 in modular unit sizes (1000x500x500 mm) - similar to the principle of Lego ^® bricks - with the, for example, in NL 1 023 479 C2 system described are compatible, facilitates the technological and constructive connectivity of the proposed solution.

Differing from the in the Figs. 1-3 In the construction shown, the structure of the system building blocks 10 can also be changed in such a way that the blocks cannot slide off one another due to forces acting exclusively horizontally (positive locking), as is fundamentally possible with commercially available concrete blocks. For this purpose, for example, the beveled edges of the in 1 shown knobs 3 at their contact surfaces with the Cover plate can be shortened to form a step. As a result, the base area occupied by the knobs 3 can be reduced or kept the same by adjusting the slope, with the dimensions of the corresponding recesses on the underside of the system module 10 not being changed in either case. When dimensioning the knobs 3 and recesses, the manufacturing tolerances to be assumed for the described concrete building blocks 10' are of course taken into account. This design, which features stepped knobs, prevents stacked system components from shifting sideways.

The concept used of correspondingly arranged recesses and projections (nubs 3) on the top and bottom, which - taking into account the tolerances customary in the art - are correspondingly dimensioned, as well as their respective compatibility with equally diverse concrete blocks 10 ', ultimately offers a large variety of possible shapes and sizes reachable fragment protection walls and cages.

As mentioned at the beginning and exemplified in 4 shown, splinter protection cages 100 that are completely covered on the top side can also be provided. For this purpose, according to one embodiment, relevant system building blocks 10 are connected to one another in rows or rows with suitable and optionally releasable fastening means - for example screws with corresponding nuts - and - to a certain extent laterally tilted and laterally connected to end faces - as a "cover" on correspondingly arranged splinter protection walls 100 of the same height hung up. Advantageously, the top 4 of the corresponding top row of the system building blocks 10 _o has no nubs 3 . However, according to a modified embodiment, the system module 10 can also be provided with recesses on at least one of its large side surfaces, which are arranged to match the arrangement of the nubs 3 on the upper side 4 . Since the side surface of the system module 10 is formed by end faces of hollow profiles 5 and (steel) sheets 6, corresponding recesses (receptacles) can also be made later, if necessary, for example with a welding torch. The core of the invention is the linking of the robustness of solid steel profiles, the geometric arrangement as guiding channels with the contour of the system blocks of concrete blocks based on the basic principle of Lego ^® blocks.

Advantageously, the proposed system building blocks 10 enable extreme robustness of the splinter protection walls 100 and cages 100 that can be built from them the material costs are.
