Description

The invention relates; to a watt module which Is formed as a precast concrete component for erecting a structure It also relates to a structure, in particular an operating or plant building of a nuclear power station, which is produced using wall elements of this type.

Safety-relevant buildings of nuclear power plants., for example those buildings which, house the emergency power systems, have until now been designed almost exclusively as concrete structures which are cast in-siiu. The precast method of construction tried and tested In conventional residential building construction has hitherto hardly been used.

The high safety requirements and taking into account Internal events (IE) and external events (EE) fer nuclear t»ef plante usually result in a very high reinforcement density. For this reason, the majority of building structures Of nuclear power stations or ether nudear power plants are designed as solid constructions. In the case of this construction, the minimum waii thickness up to now was approximately 0.85 m as a result of the large amounts of reinforcement

The buildlng/the sÉusÉuhi specifically has to withstand all loads and load connections from the following events in categories H1-H4 .

Normal; operaion (H1): constant toads, vanabie loads including loads caused by transport and installation, and combined loads.

Influences produced by events caused externally Involving persons (H2): explosion, flying machine crashes, and outdoor fires. tnlneooes produced by internal unforeseen events - in-house firs, collapse of internal design, falling leads;, internal flooding, and · internal explosion. earthquakes, extreme winds, extreme snow and formation of ice, tornado loads, influence of tornado projectiles, extreme external temperatures, extreme flooding. extreme precipitation;, physical protection, explosive blast wave, and explosive gas cloud.

The use of precast components ~ although deemed to be completely desirable on account of the associated standardising and optimising of the entire planning, design and construction processes ~ has thus far encountered considerable difficulties in this context and has therefore not materialised. This is due, in particular, to the connection techniques which have been used thus far in precast construction and which either do not meet the requirements imposed m the nuclear sector or are not capable of overcoming the admissible component tolerances Which generally have to be met.

For every nuclear power station, essentially the same buiMngs having the same function are planned from sorafeh, which leads to deiibemtion over how the planning and execution costs car· be reduced. A reduction is possible by means of systems which enable the desired spaces and their occupancy to be planned in a flexible manner by using precast modules. îfie requirements which are imposed ön the structures in Ide tieid of nuclear power stations correspond to the highest requirements m structurai and safety engineering. The planning: ansi execution is consequently very complex and cost-intensive.

The introdu#ioo of precast construction has thus far encountered dliiooiles; with regard to the fbtee"locibng connection detween the individual structural elements and to overcoming the associated tolerances and dimensional inaccuracies as weil as alignment inaccuracies during assembly. A wail module having the features of tie preamble of claim 11s known from US 2 920 475 A. In this document, possible manufacturing and alignment inaccuracies during assembly of the wall modules are compensated by holes in connection elements being widened by means of a : reamer or a milling cutter In a precisely fitting manner, before bolts having a ll which Is as precise as possible are inserted DE 2 215 352 A1 discloses a connecting element for reinforcement rods of precast conefete components having a clearance fif inside an axial drilled hole.

The afpci: of the Invention is to provide a wail module of the type mentioned at the outset which; can be combined! with: and connected to additional wall modules of this type, in a simple manner, to form a structure. In particular a bidding or building complex, which is not only designed for conventional operating loads hut furthermore withstands even unlikely extreme loads --- individually or even in oembinaion--tor instanoe flooding, earthquakes, incessant rain,: lee loads, wind loads, hurricanes, extreme ambient temperatures, projectile impact plane crashes, etc.

This object is achieved according to the Invention by a wall module having the features Ü independent claim 1,

Accordingly, a wall module is provided which is formed as a precesi concrete component for erecting a structure and! has a wall body which has a regular, in particular rectangular, base, a plurality of, in particular tour, edges and a plurality of reinforcement rods which altogether form: a regular reinforcement grid, preferably each extend in parallel with the edges and are cast Into the wail body, each of the reinforcement rods penetrating the wail body substantially from edge to edge and being provided on their ends with connecting elements designed for producing a connection to complementary connecting elements of a directly adlacent wall element, and the respective connecting element - in each ease in the released; state not connected to a complementary connecting element - being connected to the associated reinforcement rod either Ä pay or movably seed that it is displaceable, in a plane perpendicular to the longitudinal direction of the reinforcement rod, .on all sides by at least 2 millimetres in relation to a provided central position. this mobility can be completely prevented when in the tensioned, rigidly connected: state. 1t'|&:padi^tarÎy:advadtâgiêopii':âddsuiioëni^'d|udiT^yirem;ente:fn::the^Mnatrycflq«î':of' nyciear power stations If d dsspiaceability by at least 5 millimetres, preferably by up to approwmsfely 10 millimetres, Is ensured

The term wall module in this case Is to: fee interpreted in a bread sense and In particular also includes: floor end ceiling panels in addition to inner wall: portions and outer wail portions (side wails) of a building;,

Although level, flat wall modules, in particular having a rectangular base, ire preferred, the wall modules dan also be Curved such that, for example, it is possible to erect a curved wall porion or a cylindrical 'building (reactor building,: etc.).

As lias been shown in a surprising manner, In this way not only Is a flexible oonneoion established between the individual modules which makes it possible to bridge unavoidable component tbierendes and alignment tolerances in the caseof on-site assembly, but also, Where there Is suitable dlmenslonlhg, In spite of - or even precisely because of - the comparatively high level of flexibility of the individual connections, It is possible to form heavy-duty bonds between Wall modules which withstand high shear forces and bending tombes and ensure reliable load removal over the module boundaries into the respective anchoring points.

It Is : .expedient when the connecting elements - ih each case In a primary manner-are configured to be Ihteroannected: ih a force-locking manner, in particular by a screw cenheotion or clamping. Where applicable,, form looking: can also be provided, in pâffidpiér for securing screw connections: produced previously.

In a preferred: embodiment, at least two reinforcement rods which extend In parallel are csmblned to form one unit in each case and are connected at the ends to the same connecting element:.

As already indicated above, the respective wall module can be a component of a side wall or of a ceiling wail or floor panel and is therefore either vertically or horizontally aligned. Accordingly, in tbs installed of assembled state, doth vertical and norizootairrolnforesmeni rods are provided with veriest or horizontal conneoilng elements connected thereto in order to intorcohnect side wail modules and to Interconnect ceiling wall modules and to tmernonnect side wait modules and celling wall modules. fn an adyardageous embodiment, a Wall module is provided in which reinforcement reds which extend horizontally when in the assembled state are rigidly connected, in particular welded, at the ends to a support element which has at least one holding plate, the respective holding plate being encompassed by a U-shaped saddle element having a base plate and two leg plates, end the leg platesin turn ip in particular welded, to an associated horizontal connecting element. The saddle element is preferably formed in one piece.

In this case, in the assembled state, the base of the saddle element expediently abuts an end face of the holding plate and is dimensioned in particular with regard to the distance between the leg plates In such a manner that the above-mentioned flexible seat is termed. This means that, in this variant, the reguired flexibility of the connection Is preferably produced by the displaeeabiity of the saddle element relative to the holding plate.

In a preferred variant, the respective support element consists of one single cuboid holding piste: which Is rigidly connected, in particular welded, to a total of two reinforcement rods. in an alternative variant, the respective support element comprises two cuboid holding plates which are Interconnected by twc cuboid cross pietés, the support element being rigidly cormeofed, In particular welded, to four associated reinforcement rods and each of the two holding plates being encompassed by a saddle element which is connected to a horizontal connecting element In this variant, a connecting unit which Is located in the wail module therefore comprises a total of four reinforcement rods which extend in parallel and are each provided at the ends with a connecting unit having two: connecting elements

The support element that is frame-like m this variant can also be formed In onp place in a preferred embodiment.

In a particularly pmferted embodiment the female version of the ^si^riive feofeonfa! connecting element comprises a bushing which is provided with an internai thread and the complementary mate: version comprises a threaded holt which Is provided with: an external thread and has an associated locknut, the male connecting element and the female conneehng element, When interconnected, preferably interacting in the form: of a turnhuckle.

In this case, the respective bushing on llmend facing the sopport eiementils estpedtedfly screwed onto a threaded bolt which Is provided for fastening to the saddle element.

In addition, a structure is advantageous in which the leg plates of the respective saddle element are aligned in parallel with the horizontally extending reinforcement rods and have receiving slots which extend In parallel therewith and are delimited by slot edges, the respective threaded bolt of the associated connecting element being pressed along the readying slot between the leg pletes and being rigidly connected. In particular welded, to the leg plates in the region of the slot edges.

The variants described thus far are particularly sutafele for horizontal reinforcement rods and horizontal connections. Variants which are particularly suitable for vertical connections are described below. th an advantageous embodiment, a wall element is provided in which reinforcement rods Which: extend vertically when in the assembled: state are rigidly connected, in particular Welded, at their ends to a support element which has ai recess for the passage of a threaded bolt which Is provided: with an external thread and, as it Interacts with two serewedmn anchor nuts and optionally present anchor plates which are penetrated1 by the threaded bolt, acts as a vertical connecting element.

The above-specified flexibility of the vertical connections is expediently achieved in this case ly the threaded bolt having a: somewhat smaller diameter than the seat which surrounds it and is formed in particular by an associated recess In the support element or by a corresponding recess in an anchor plate in this case, if is expedient when the respective support element compnses four cuboid frame# fates.which, are interconnected, in the manner of a rectangular frame, wherein two frame plates which are opposite one another are designed as holding plates and are each rigidly connected, in paftiedigf welded, io é reinforcement rod, Therefore, a vertical connecting: unit irr the wait module preferably has two reinforcement rods.

One design of the wail module is advantageous for ali variants described thus far in which the wait body Jo a eandwtch constructiOd, has an outer she!, an inner she! and a core fling toted therebetween, the outer shell and the inner she!! being Interconnected in a shear-resistant manner by moans of;·reioforcemeot elements: which,: in addition to the: reinforcement rods of the connect!ng unis, can include additional elements.: A structure which is composed of a plurality of wall modules of the stated type which are irderoonnected by the flexible connecting; elements meets the requirements stated at the outset in art: excellent: manner.

In m expdlent manner, joints which are present between the wait modules when erecting the building and recesses which may be present In the region of the connecting elements are cast with concrete in the respective wall body .

The system proxies proposed and explained thus far has a very high leÄ of lexibility and at the Same time results in staddamisatiOh and optimisation of the entire design, planning and construction process.

The system can be applied to ail buildings which, as a result of their function in the installations, have to withstand thb aforementioned external: and Internal events. This means that the system is not only applicable to nuclear power plants but can also be used in chemical, military and other fields.

The element connections w® configured such that the established minfomemenf values ean; be transmitted in the form of a solid joint (1¾ % force transmission). Each reinforcement rod is connected to the mintbreemenf of the fdlicwing component in such a design:, irespecive cd whether the possible capacity to withstand stresses is reached. iAIfhough different types of connectors for the wail elements have already been described,: which have also been designated as wall modules In the previous description and meet the requirements posed in an excellent manner, there is a: need for further types and modioafions to the existing: types ln orderte provide flexible detailed solutions for the different requirements, in this case, in particular as regards the design and the material requirements, oosfnsflolenf connectors or connector systems are sought which are retained in a simple manner and nan de connected simply and reliable to thé Mfirnmmtë #tb© wag elements end to one another.

To this end, e oonnector system ifor a precast construction having a plurality of well modules nan be prodded, the connector system comprising one or more components from fie following group: * a U-bsam or a box which Is arranged In the joint between two wall modules and by means of which the reinforcement rods (10} are screwed together, * a U-beam or a box whfoh is arranged in the joint between two wail modules and in which the reinfohfeolenl rods engage in a positive-locking manner by means of spfdwddroh metal daws. * a bphd between two end plates dr boxes which ere interconnected by screw bolts, each end plate of each box being screwed to one of the reinforcement rods, and » a double-headed anchor;

In an advantageous variant, the precast component system according to the invention has a wail thickness of just S,4S m and an optional facsng formwork having a thickness of approximately $.10 m. This means that all the above-described loads arid load connections are reliably absorbed.

The advantages obtained by means of the invention consist In particular in that, by providing a “modular system" with precast, stshdardisedwat modules C? wal profiles which am provided with bigh-guaiity and flexible connections, the advantages which have always been known from conventional precast eonstrudionWilh respect to planning time and execution time as well as; costs and: efficiency can be transferred to the construction of buildings for nuclear power plants. However, the invention Is naturally not limited to these types of applications but can alee be used, for example, for non-nuclear Industrial plants, military Installations or even for oDOvenfiona! buildings, for Instance in regions where them Is a high risk of earthquakes.

The waif meddles· 2 according to the present invention are formed as precast concrete components having connecting units 4 which are partially cast in concrete., connecting elements & for connection to complementary connecting; elements § of corresponding adjeoeht modules protruding or projecting outwards from of the respective wail body 8,

Fig, B ;s a perspective view of a first type of a horizontal connecting; uni 4. The connecting unit 4 comprises two Enforcement rods 1-¾ which extend in parallel are the same length and are welded at their respective ends to the end faces of a cuboid holding plate 12. the respective holding plate 12; is encompassed hy a U-shaped saddle element 14 which has a base plate 16 and two leg; plate 18. in a preferred manner, the respective saddie element 14 is formed as one piece (in this case, however, a variant which Is composed of a plurality of individual parts Is shown) and ;s aligned in such a manner that the leg plates 18 to a certain extent form an outward extension of the reinforcement rods 10 which In turn continues outwards in the form of a connecting element 6 which is aligned in parallel with the reinforcement rods 10.: The respective connecting element 8 composes a threaded Pölt 20 which is provided with an external thread, engages between receiving; site 22 in the two associated leg plates if by way of its inner end and is welded to the Mg plates 18 on the slot edges 24. The outer end of the respective threaded bolt 20 is either a female version; which Is provided with a bushing 28 which has an Internal thread ora male version which is provided with a locknut 28 such that a corresponding forcedocking connection in the form of a tumbuokle connection can be pmduMd; between complemehtafy conneotihi elemeris 6 of ad|aoenf wall modules 2.

By dimensioning: the components in a conesponding manner. In particular the length w4 width of the base plate 16 of the respective saddle element 14 In relation to the length and width of the holding plate 12 of the holding plate 12 which is encompassed by the saddle element 14. a certain lateral displaceabiÄy of the saddle element 14, and consequently also of the associated connecting element 8, is ensured in relation to the reinforcement rods 10 which are fixedly oast In the wall body 8 of the wall module % in particular by at least 2 mlimetres, preferably at least $ millimetres .in any direction: which is perpendicular to the longitudinal direction of the reinforcement rods 10. The substantially cuboid wall body 8 is provided with a corresponding recess in the region öf the respective saddle element 14 such that the displaoeabilityls actually provided, in this way, where required, unavoidable component tolerances during the production of or during the tightening of the connections can be compensated.

The second type of a hohcontat Connecting unit 4 shown in Fig, 7 is constructed in a very similar manner with regard to function, but has twice the: number of connecting elements δ and of reinforcement rods 10. Therefore, two holding plates 12 which: are each encompassed by e: saddle element 14 having ah associated connecting element 8 and ere arranged in parafe! are provided on each side, the holding plates 12 being interconnected by cross plates 30, The frame which is formed by holding plates 12 and cross pistes 30 can be formed In one piece. The reinforcement rods 10 are welded to the end faces of the holding plates 12, or alternatively to the cross plates 30, in this way, tea certain extent a double furnbuÄ ooenecioh which has the abova-deschhed flexibility can be established on each side of the connecting unit 4.

Fig, 8 shows a vertical connecting unit 4 having a%ndamenfafiy similar operating principle, but the design of the connecting elements β is different in detail. The two reinforcement rods 10, in this case, are specifically welded at the ends to a rectangular frame which is formed by four frame plates :32:. An anchor plate 38 which is provided with a central recess 34 is welded onto the frame plates 32 on the Inner surface of the reotinguiet frame which faces the reinforcement rods TO. The diameter of the recess 34 Is such that a threaded bolt 38, also referred to as an anchor bolt, is able to be inserted through with a certain amount of play, i.e. so that an annular gap is formed. An anchor nut 40 serves for strengthening and fixing a connection which is produced by way of a mating part of an adjacent wall module 2 end is fihewsse fixedthere by a corresponding anchor plate 36 which is penetrated by the threaded bolt 38. Differentiating between male and female connection types, in this case. Is not absolutely necessary , let cm naturally be provided in m alternative embodiment. As an: attematlve to this, clamping bushes or the like can also again be used here in order to interconnect the opposite ends of threaded bolts 38 of adjacent wall modules 2

It is important, once again, for the vertical connection, similarly to the horizontal connection, to allow for a certain degree of flexibility perpendicular to the longitudinal direction of the reinforcement rods 10 of at least 2 millimetres, preferably at least 5 millimetres, of adjustment clearance, tn all oases, thrust loads, tensile loads and sheas loads are reisabiy removed and passed on by the reinforcement rods 10, all ofwhich are cast In the concrete bitbe wall body S in the: manner of a regular, rectangular grid. AH the components, which, in the figures, are composed of individual components welded together (weld seams 42), cam in an attemaive embodiment, also be formed in one piece, for instance cast or produced by cold or hot forming.

The types of connectors described below can take the place of the conoeefbrs which are shown in Füg. 1 to 11 and which have been described ~ referred to as '’connecting elements'1 therein ^ and can replace these either in part or completely or can also be combined therewith or interact therewith: in numerous ways.

Several embodiments of connector systems, according to the invention, for precast; Telhfomsd: Concrete wall modales are explained! to more detail in 1%, 12 to 30 by means of drawings.

The following applies to all the examples below: the building is formed as a solid structure produced tom precast elements or prefabricated reinforced ôonorete modifies In the form: of wall elements, ceiling elements,: comer elements and the like, summarised in short below by the term “wall module", the term: ‘'walt eiemenf being used Syfmhymbusfy. The connections between the precast elements are managed by way of special connectors or connector systems based on screw connections. The precast wall modules can he combined in an atmest arbitrary manner.

The screw connections meet the requirements for cyclical alternating; stresses in the event of the action of earthquakes or In the case of comparahie natural; ®*sts as well as In the case of extraordinary loads, for example explosions or Impact loads.

Fig. 12 m a perspective » of an example wall portion which is composed of th ree Identical, rectangular wall modulas 2 1, UdNam^pe screw cormection

Continuous U-haams. i.a. which preferably extend over the entire edge length of one or more elements,; are arranged between the precast elements which are formed in; particular as mini oread concrete elements and are provided with mdsions/elengaf e holes In accordance with the reihforcement Intervals of the reinforcement grid, To compensate tolerances, said ineisions/eiongate holes should Pa provided with oversize in relation to the screw connections of the reirfecerneht rods which are pushed through said Ineisions/eiongate holes.

The thickness of the U beams should be at least 20 mm, with 2d mm being recommended. Attachment to the concrete elements occurs by means of nuts which are screwed to the protruding reinf ornement rods or bers, the ends of which are provided with a corresponding thread.

Since the elongate noies in the U-heams have to have considerable oversize in reletion to the sprew connections In order to compensate tolerances, washers or screws/nuts having a machined'öfí collar ere expedient in order to ensure sufficient contact surface.

The U-oeams are pushed under the connectors and are screwed on. dl & fcstrsied· byway of ft Fig.. I S and Fig;. 14,

In this case Fig. 13 shows a section through a vertically aligned wall module 2: in this case having: ah; associated facing formwork 1003. The U-heams 10Ö4 can be seen oh the fop edge and the bottonr edge of the well module 2, by means of which U-heams the connection to the adjacent wall modules (not shown: here) is established. The U-beams 1004 each abut the edge faces of the associated wall modules by means of their legs IQOb and to a certain ekteht form spacers between adjacent wall modules. For a secure connection between the U-beam 1004 and the wail module 2, the ends (screw pbhneetipns;) of the reinforcement rods 10, which ends project out of the wall element and are provided there with an external thread, are guided through associated elongate holes in the leg of the U-feeam and are each secured by a locknut 1010 which is screwed on from the outside.

Th« diameters of the bores/eiongate holes in the logs 1008 of the UOeams 1004, through which bores/hoies the ends of the reinforcement rods 10 are guided are generously dimensioned such that the reinforcement rods 10 have corresponding play, preferably at least 5 mm in each direction, when the locknuts 1010 are loosened.

In an advantageous manner, the reinforcement rods 10 each penetrate the entire wail module 2 tom edge to edge or from connection point to eonneotien point; This means that the respective relnfdr<^ment rod 10 has, at both ends thereof, a connector of the above·' described type which interacts with an associated connecter of the adjoining wall module. The two connectors on the opposite ends of one reinforcement rod TO are preferably the same type and have the same dimensioning. The same also applies to the further connection types described further below.

Fig, 14. is a plan view of the connection between two wall modules produced In this manner. Only the horizontal retntdmement rods 10 can be seen of the wail modules themselves In this simplified view.

In the case of a correspondingly produced reinforcement grid, both vertical and horizontal connections between adjoining wall modules can be produced in this manner. 2* Box hype screw connection

The box-type screw connection described below is aiso suitable for both horizontal and vertical connections.

This connection type is Illustrated by way of Fig. 16 to 18. in this case, the left-hand naif of Fig. 15 is a perspective view of the reinforcement grid 1012 of a reetangaiar wali module 2 having boxes T0T4 which ere each connected to the reinforcement rods 10 at the end. In the right-hand bait of the figure, the wall module 2 is shown In the delivery state vith appled oohP^e casting ccmpeund. Each of the boxes 1014 is connected to an associated hex 1014 of the adjacent wall module 2 by means of a screw connection when the wall modules 2 are joined together.

Rg. 16 shows a longitudinal section through a box-box combination which is interconnected in this way: at the connection point between two wall modules 2 .

Fig. 1? and Fig. 18 show two cross sections correspondingly marked Oy roman numerals in

Fig, 16. ön the side which laces the watt module 2,. the respective box-1014 is connected and fixed to the end of a reinforcement rod 10. This is earned out by means of a LENTÔN screwed" gland connection10l6 or in a similar manner. To this end, the end of the reinforcement rod 10 which· tapers conicailyand sleeve 1018 or screw socket which has a complementary shape and forms an Integra! component of the box 1014.

The two boxes 1014 having identical constructions are interconnected by an interna! connecting bolt 1020 which is provided in each case with an external thread at both ends and penetrates an associated bolt channel 1022 The screwed-on locknuts 1024 each act, by means-of an anchor piste 1026 which lies between the locknuts, on the annular sleeve 1828 of the associated box 1014, which sieeve deines the bolt channel 1022. and thus fix the arrangement; in place,: In this case, the annular end face 1080 of the respective annular sleeve 1028 forms a contact face, which acts as a stop, for the anchor piate 1026 which is in the form of a slotted washer. As a result, the annular sleeves 1028 of the two boxes 1014 and therefore the two boxes 1014 as a whole are pressed: irmly against one clamped state.

Since, on the one hand, the Inner diameter of the bolt channel 1022 is greater than the outer diameter of the connecting Pot 1020, on the other hand trie respective anchor plate 1026 has sufficient space for movement inside the enclosure which is formed by the walls of the box 1014, and finally since there is also still a sufficiently large axial gap between the respective locknut 1024 end the threaded sieeve/screw socket 1018 located opposite sale nut, a very adaptable connection is created:. The space for movement in all three spatial directions which is provided when the locknuts 1024 are not yet tightened is preferably at least S mm in this case. 3.. Terminator4ype screw connection A further connection type, aiso suitable for both horizontal and vertical connections, is instated in Fig. 19 to Fig. 28.

In fils case. Rip. 21 is a perspective vie® of m individual connector and Fig. 22 is a pian vie® thereof. Fig. 23 to Fig. 26 show different sections through individuai components of the connector.

In this type of connection, the respective re|ntdrce?oenf: rod 10 of the wall module 2 is anchored at its ends m an end plate 1034 which is also referred to as a terminator. This can occur in particular by means of screwing, for instance using a LENTON screwed-gland connection or the like, the threaded sleeve 1036 or screw socket being inserted and fixed in a positive-locking manner in a oortespondpg bore through the end plate 1034 (see Fig. 24).

The connection between two end plates 1034 is produced, in turn, by screw bolts 1036 which penetrate associated bores through the end plates 1034 and are secured: by means of huts 1040. Correspondingly bond steel plates 1042 to some extent act as washers between the nuts 1040 and the end plates 1034.

Two screw bolts 1038 which are arranged symmetdeally ahi In parallel with the central axis of the reinforcement rod 10 are provided in the embodiment.

Once again, the effective adaptability ofthe connection for adapting to; unavoidable production tolerances or dimension Inaccuracies; as weli as alignment inacouraoles during assembly are al so important In; this case. For this reason, the Inner diameter of the bores, which are penetrated by the screw hois 1038, In the end plates 1034 is greater than; the outer diameter of the respective screw bolt 1038 such that, when the nuts 1040 ate released m loosened^ the desired freedom of movement fie. : play) of preferably more than 8 mm In all directions is produced. This can be seen, for example, in Fig. 24 and Fig. 26. in an expedient manner, the length of the screw Potts 1038 is such that, In the assembled state, a significant gap remains between the two interconnected end pistes 1034. When finishing the buiiding which is composed of the wail modules 2, these types of gaps are advantageously Cast with a filling compound, for instance fine-grained concrete or mortar This also applies ansibgbusiy to gaps, joints and: spaces at the joint points between adjacent wait modules in the case of the other types of connections described here.

The distance between; adjacent, parallel reinforcement rods 10 of the reinforcement grid 1842; which can he seen In Fig. 20 is typically In the order of 280 mm. This value should also form the basis for Instance in the ether connection variants described here, considerable wiattes-öbviou^f feeing pesäifefe ;d:epeiAf m the application,. a typical value fm the diameter of the screw holts 1D38 is in the order of 20 mm or more, & Claw-type ! screw connection

This connection has a certain similarity to the U-feeam-t^pe screw connection. The screw; connection of the reinforcement rods Is not managed with sockets, but rather metal claws are screwed onto the ends of the reinforcement rods which ensure the solid joint, In addition, a metal plate, which; completes the support profile to fám the closed; rectangular ring, is screwed; onto the Uhfeeani, In an expedient manner, the joint between the wall modules Is reseated,

This is shown by way of example in perspective In fig;. 26 and In section in Fig. 27. f ig, 2? shows the metal claw 1 048 which is connected to the respective reinforcement rod ID, It Is; temed in one piece and has a threaded sleeve 1048 which Is screwed onto the reinforcement rod; 10 and; a holding teg 1050 which; is arranged at a right angle to said sleeve and protrudes laterally, the end of the reinforcement rod 10 haying the threaded sleeve 1048 Is guided through a bore, provided with significant play, In the leg 1052 of the U-beam 1054 such that the holding leg 1050 of the metal claw 1 Q4i is held In place Inside the U~ beam 1054. The metal plate 1058 which is screwed onto the U-beam 1054 closes the U-proflle to firm a box.

Similarly to the U-beam-type connection,: the hex; Which Is arranged between the two interconnected wall modules 2 preferably extends over the entire edge length:thereof. §i Ctawdype It screw eonnecion in this type of connection, in an analogous manner to the claw-type I connection, the ends of the: reinforcement rods 10 are provided with screwed-on metal claws 1080. Deviating from this, however, the U-eiamp 1062 does not extend over several or al of the connections of a aide edge of the respective wait module 2, but only over the cermector tsel. Fixing occurs by screws 1054 which extend perpendicularly to the longitudinal axis of the reinforcement rods 10, as shown; in perspective in Fig. 28 and; in section in Fig. 29 finally, as an alternative to or in addition to the types of connections described thus far If is possible to use double-headed anchors, which are countersunk into corresponding recesses in the wail modules, as connecting means. The possibility of transmitting the tensile force of the: corresponding wall joint m ensured as a result.

The connecting system Is illustrated by way of example In Fig. 30 by means of a section through tw'o lhtaroonnected1 wa! In said example, two deubtecl--headed anchors 1070 which are arranged at right angles to one another are combined to form an anchor cross 1072. In particular, the two double-headed anchors 1070 can be rigidly Interconnected at the point of intersection of the anchor cross 1072. The anchor cross 1072 can also be cast in one piece. As ah alternative to this, it is of course also possible to use single double-headed anchors 1070.

Each double-headed anchor >070 has two thickened, radially protruding heads 1074 which are ptegralty formed on the end of an anchor rod 1078 and are fixed In a positive-lacking manner In corresponding recesses or grooves In the associated wall module 2 >n each case, in an expedient manner, the recesses are sealed with a filling compound, for instance mortar or lightweight concrete, alter assembly.
