Description

  The present invention relates to a building wall module for a building formed as a precast concrete member. The invention further relates to a building manufactured using such a wall module, in particular a nuclear power plant operation or equipment building.

  Buildings important to the safety of nuclear facilities, for example, buildings containing emergency current facilities, have been implemented almost exclusively as on-site concrete structures. The prefabricated style that has been proven in ordinary residential buildings has not been used in practice.

  In view of the high safety standards for nuclear installations and EVI (internal action) and EVA (external action) loading cases, the rebar density is generally very high. For this reason, many building structures in nuclear power plants or other nuclear installations are implemented in a robust construction style. In this construction style, the minimum wall thickness is conventionally about 0.85 m due to the large amount of reinforcing bars.

That is, the building or structure needs to withstand all loads and compound loads due to the following category H1-H4 events.
Normal operation (H1)
-Permanent load-Variable load including load caused by transportation and installation-Effect of human factors from outside the combined load (H2)
-Explosion-Airplane crash-External fire Unexpected internal events (H3)
-Fire on internal operation-Collapse of internal decorations-Falling objects-Internal flooding-Internal explosion abnormal event (H4)
-Earthquakes-Storms-Heavy snowfall and freezing-Effects of tornado loads and tornadoes-Extreme external temperatures-External flooding-Extreme precipitation-Objective protection-Explosive pressure waves-Explosive gas clouds

  Although the use of prefabricated members is considered highly desirable for the standardization and optimization of the overall planning, structure and construction process, it has hitherto encountered significant difficulties and therefore has not been done in the context of the above. . This is because, in particular, the joining technique conventionally used in the prefabricated structure does not satisfy the demands imposed on the nuclear field, or is not in a state where tolerances between members generally found can be overcome.

  In view of the fact that a similar building with almost the same function is planned for each nuclear power plant, consideration has been given as to how the planning and implementation costs can be reduced. The cost reduction is made possible by a system that allows elastic planning of the desired space occupancy with pre-made modules.

  The demands placed on structures within the scope of nuclear power plants are comparable to the maximum demands on their construction and safety technology. Planning and implementation is therefore very labor intensive and costly.

  The introduction of prefabricated building structures has hitherto been difficult in terms of overcoming the force-coupled joints between individual building components and the associated tolerances, as well as dimensional inaccuracies and adjustment inaccuracies during assembly. It was.

  Therefore, the problem of the present invention is that it is possible to design a single building, particularly a building or a complex building, by simply joining another wall module of this type and corresponding to a desired operating load, Not only that, but also for unusual loads such as floods, earthquakes, long rains, freezing, strong winds, typhoons, extreme environmental temperatures, gunshot strikes, airplane crashes etc.-each of them It is to provide a wall module of the type mentioned at the outset that can withstand, individually or in combinations thereof.

  This problem is solved by the features of independent claim 1.

According to this, a wall module for building construction, formed as precast concrete, has a regular, in particular rectangular base surface, a wall body with a plurality of, in particular four edges, and a total of 1 A plurality of reinforcing rods, each of which forms a regular rebar grid, preferably extending parallel to the edges and poured into the wall, each of the reinforcing rods approximately passing from edge to edge, at its end provided with a joint member, the joint member is formed to make the bonding with a complementary joint member directly adjacent wall member, In any case, in a released state that is not joined to a complementary joining member, it has play or is movably joined to an attached reinforcing bar, and a surface perpendicular to the longitudinal direction of the reinforcing bar Less than a given central position in all directions Has become can be moved even over two millimeters. In the fixedly joined state, this mobility can be completely eliminated.

  For normal requirements in nuclear power plant buildings, it is particularly advantageous and sufficient if the mobility is guaranteed to be at least 5 millimeters, more preferably to about 10 millimeters.

  The term wall module is to be interpreted broadly here and includes, in addition to the interior and exterior wall parts (side walls) of the building, in particular floors and ceiling boards.

  In particular, a flat and planar wall module with a rectangular base surface is advantageous, but the wall module can also be curved, for example a curved wall part or a cylindrical building (reactor Building).

  Notably, in this way not only the elastic joints between the individual modules are formed, but also the appropriate dimensions, allowing adjustment of inevitable inter-member tolerances and adjustment errors before field assembly. Depending on the setting, it is possible to achieve wall module joints that are highly resistant to loads, despite the relatively high individual joint elasticity, which withstands large shear forces and bending moments. It will also ensure reliable removal of the load across the module boundaries to each anchor point.

  In any case, it is more desirable that the joining members are designed primarily for joining by force coupling, in particular by screwing or tightening. In some cases, a shape connection can also be performed, in particular in order to ensure a pre-applied screw connection.

  In an advantageous embodiment, at least two rebar bars extending in parallel are grouped together in one unit and joined to the same joining member on the end side.

  As mentioned above, the wall module can be formed as a component of the side wall or ceiling wall or floorboard and thus arranged vertically or horizontally. Accordingly, in the assembled or assembled state, the vertical or horizontal reinforcing bar, together with the vertical or horizontal joining member joined thereto, not only joins the side wall modules and the ceiling wall modules but also joins each other. Is possible.

  In an advantageous embodiment, the wall module is fixedly joined, in particular welded, to a carrier member having at least one holding plate on its end side, which is horizontally extended in the assembled state, each holding plate being connected to the substrate and two It is gripped by a U-shaped saddle member provided with leg plates, and these leg plates are fixedly joined, particularly welded, to the attached horizontal joining member. The saddle member is advantageously formed in one piece.

  In this case, in the assembled state, the saddle member is advantageously set to abut against the end face of the holding plate at its base surface, and is dimensioned so as to realize the above-mentioned elastic seat between the leg plates. That is, advantageously, the required joint elasticity is realized by the possibility of movement of the saddle member relative to the holding plate in this variant.

  In an advantageous variant, each carrier member consists of a single rectangular holding plate and is fixedly joined, in particular welded, to a total of two reinforcing bars.

  In an alternative variant, each carrier member has two rectangular holding plates that are joined together via two rectangular transverse plates, and the carrier member is fixedly joined to four attached reinforcing bars. In particular, it is welded and one of the holding plates is gripped by a saddle member joined to a horizontal joining member. Therefore, in this modification, the joining unit in the wall module has a total of four reinforcing bar bars extending in parallel, and these reinforcing bar parts each have two joining members on their terminal sides. Is provided.

  In an advantageous embodiment, the frame-shaped carrier member in this variant can also be formed in one piece.

  In a particularly advantageous embodiment, each horizontal joining member comprises a bush with an internal thread in the female mold, whereas the complementary male mold comprises a screw bolt with a counter nut attached to the external thread. The male joint member and the female joint member cooperate with each other in a coupled state, and preferably form a turnbuckle.

  In this case, preferably, each bush is screwed into a screw bolt provided for attachment to the saddle member at the end on the side of the carrying member.

  Furthermore, the leg plate of each saddle member is oriented in parallel with the reinforcing bar extending in the horizontal direction, and in parallel therewith has a receiving slit limited by the slit edge, and each screw bolt of the attached joining member is A structure that is pressed between the leg plates along the receiving slit and is fixedly joined, in particular welded, to the leg plate at the slit edge is advantageous.

  The modifications described so far are particularly suitable for horizontal reinforcing bars as well as horizontal joining. A modification that is particularly suitable for joining in the vertical direction will be described below.

  In an advantageous embodiment, a reinforcing bar extending vertically in the assembled state is fixedly joined, in particular welded, to a carrier member having a notch for penetrating a screw bolt with an external thread on the end side, said screw bolt Constitutes a wall module which acts as a vertical joining member in cooperation with two threaded anchor nuts and optionally anchor plates through which threaded bolts pass.

  The elasticity described above in detail for the vertical connection is in this case the seat diameter which is realized by a corresponding notch in the carrier member or a corresponding notch in the anchor plate, in which the screw bolt surrounds it. This is advantageously achieved by having a smaller diameter.

  In this case, each supporting member has four rectangular frame plates joined to each other in the form of a rectangular frame, and two frame plates facing each other are designed as holding plates, each fixedly joined with one reinforcing bar, It is particularly advantageous when welded. That is, it is advantageous if the vertical joining unit in the wall module has two reinforcing bars.

  For the modifications described so far, the wall body is a kind of sandwich structure and has an outer petri dish, an inner petri dish, and a core filling between them. The outer petri dish and the inner petri dish are joined units. An embodiment of the wall module, which is adapted to be non-slidably joined to one another via a reinforcing bar member which can have other members in addition to the reinforcing bar, is advantageous.

  Buildings constructed from a number of wall modules of the type described above that are elastically joined together via joining members will significantly meet the above requirements.

  Due to the joints and joints that exist between the wall modules during the construction of the building, the concrete is poured into the notches in each wall within the area of the joining member.

  The above described wall structure, i.e. a system with a pre-made module / wall profile, exhibits a very high elasticity while at the same time standardizing and optimizing the structure and the overall planning and construction process.

  This system applies to all buildings that need to be able to withstand the extreme internal events described above, within the facility, due to their function. That is, this system is not only applied to nuclear facilities, but can also be used in chemical, military, and other areas.

  Joining between members is taken to mean that a fixed reinforcement value is transmitted in the form of a full impact (100% force transmission). Each rebar is joined under this interpretation regardless of whether the possible load bearing is achieved in the reinforcement of the next member.

  It has been stated that the various existing types of joining members to wall members, also referred to as wall modules in the above description, can be satisfied in an excellent way to the demands placed on them. However, there is a need for different types and variants that differ from existing types in order to provide a flexible detail solution for various demand cases. In this case, there is a need for an easily obtainable and cost-effective joining member or joining system that is easily and reliably joined to the reinforcement of the wall members or to each other, especially in structural and material demands.

For this purpose, a joining system for prefabricated structures with a large number of wall modules is provided, which is the following group:
• U-carrier or box placed at the seam between the two wall modules and screwed with the reinforcing bar (10) • Shaped by a metal claws with the reinforcing bar inserted into the seam between the two wall modules U-carriers or boxes that engage in engagement; a joint plate or box union that is screwed to one of the rebar bars of the box or box that are joined together by screw bolts; It has a plurality of members.

  The prefabricated structural system according to the invention advantageously has a wall thickness of only 0.40 m and an optional front petri dish with a thickness of about 0.10 m.

  The advantages obtained by the present invention are in particular the planning and construction time and costs by providing a high value elastic joint, or a “module box system” with a wall module or wall profile with joints. And the advantages that have long been known for traditional prefabricated structures with regard to efficiency are also given to the construction of buildings for nuclear installations. Of course, the present invention is not limited to this kind of purpose of use, and can be used for, for example, a non-nuclear industrial facility, a military facility, or a normal building in an area with a high risk of earthquake.

  Various embodiments of the present invention will be described below in detail with reference to the drawings. Each figure is a considerably simplified version. The same reference numerals are given to parts having the same or the same action.

  The wall module 2 according to the invention is formed as a precast concrete member having a joining unit 4 partially poured into the concrete, the joining member 6 for joining with a complementary joining member 6 of a corresponding adjacent module. , Projecting or projecting outward from each wall body 8.

  A first type of horizontal joining unit 4 is shown in perspective view in FIG. The joining unit 4 has two reinforcing bars 10 of the same length extending in parallel, and each end thereof is welded to an end face of a rectangular holding plate 12. Each holding plate 12 is held by a U-shaped saddle member 14, and the saddle member has a substrate 16 and two leg plates 18. Each saddle member 14 is preferably formed in one piece (here shown for the time being synthesized from a plurality of individual members), and the leg plate 18 has some extension to the outside of the rebar 10. It forms and is connected further to the shape of the joining member 6 parallel to the reinforcing bar 10 toward the outside. Each joining member 6 has a bolt 20 with an external thread, and this bolt engages between the receiving slits 22 of both leg plates 18 at the inner ends thereof and is welded to the leg plate 18 at the slit edge 24. The outer end of each bolt 20 is formed as a female type having a bush 26 having an inner screw or a male type having a counter nut 28, and a turnbuckle is provided between the complementary joining member 6 of the adjacent wall module 2. A force-bonding joint in the form of can be formed.

  In particular, by appropriately setting the dimensions of each member such as the length and width of the substrate 16 of each saddle member 14 with respect to the length and width of the holding member 12 held by the saddle member 14, the saddle member 14. And in connection with this, between the attached joining member 6 and the reinforcing bar 10 fixedly cast in the wall body 8 of the wall module 2, particularly in an arbitrary direction perpendicular to the longitudinal direction of the reinforcing bar 10. A slight lateral mobility of 2 millimeters, more preferably 5 millimeters, is guaranteed. The substantially square wall 8 has a cutout corresponding to the extent of each saddle member 14, thus providing practical mobility. In this way, tolerances between components that are unavoidable when necessary can be compensated for during manufacture or at the start of joining.

  The second type of the horizontal joining unit 4 shown in FIG. 7 is formed in the same manner in terms of function, but the number of joining units 6 and reinforcing bars 10 is doubled. Therefore, two parallelly arranged holding members 12 each provided by a saddle member 14 provided with an attached joining member 6 on each side surface are provided, and these holding members 12 are joined to each other by a lateral plate 30. The The frame formed by the holding member 12 and the horizontal plate 30 can be integrated. The reinforcing bar 10 is welded to the end face of the holding plate 12, alternatively to the horizontal plate 30. In this way, double turnbuckle joining having the above-described elasticity is realized on each side of the joining unit 4.

  FIG. 8 shows a vertical joining unit 4 having a joining member 6 that has basically the same functional principle but has a different detail. That is, both the reinforcing bars 10 are welded to the rectangular frame formed of the four frame plates 32 on the end side here. Inside the rectangular frame facing the reinforcing bar 10, an anchor plate 36 having a notch 34 at the center is welded to the frame plate 32. The diameter of the notch 34 is set so that a screw bolt 38, also called an anchor bolt, is inserted with some play, i.e. under the formation of an annular gap. The anchor nut 40 serves to fix a joining member formed by the opposing tool of the adjacent wall module 2, and this joining member is similarly fixed via an anchor plate 36 inserted through a screw bolt 38. Here, it is not always necessary to differentiate between the male and female joint types, but it is of course possible to do so alternatively. Alternatively, it is also possible to join the ends of the screw bolts 38 of the adjacent wall modules 2 to each other using a clamping bush or the like.

  Again, what is important is that the vertical joint, like the horizontal joint, has some elasticity perpendicular to the longitudinal direction of the reinforcing bar 10 and an adjustment gap of at least 2 millimeters, more preferably at least 5 millimeters, It is to allow.

  In any case, thrust, tensile and shear loads are reliably received and further transmitted through the reinforcing bar 10 cast in a regular rectangular grid in the concrete of the wall 8.

  In each figure, all members and elements assembled from individual members that are welded together (weld seam 42) may in one embodiment be integrally formed, for example by casting or cold or hot deformation. It is.

  The types of assemblies described below are alternatives to the assemblies shown in FIGS. 1-11 (referred to herein as “joint members”), which may be partially or fully replaced, Or they can be combined or interact in various ways.

  12 to 30 describe in detail a number of embodiments of the joining system according to the invention for a wall module of reinforced concrete prefabricated structure.

  In the following example, the building is a solid structure composed of prefabricated members of reinforced concrete in the form of walls, ceilings, corner members, etc., or modules made in advance, and in the following abbreviated as `` wall module '', This term is synonymous with “wall member”. The joining between the prefabricated members is performed by a special joined body (connector in English) or a joining system based on screw joining. The prefabricated wall modules can be combined almost arbitrarily with each other.

  Bolt joints meet the requirements for earthquakes or comparable natural phenomena, as well as cyclical alternating loads under the influence of abnormal loads such as explosions and collisions.

  A portion of the wall assembled from three homogeneous rectangular wall modules 2 is illustrated in perspective view in FIG.

1. U-carrier type bolt connection In particular, a U-carrier is arranged between the prefabricated members formed as reinforced concrete members, i.e. extending over the entire edge length of one or more members, Are provided with cuts / long holes according to the rebar spacing of the rebar lattice. In order to compensate for tolerances, the U carrier needs to be oversized with respect to the penetrating bolt terminals of the reinforcing bar.

  The thickness of the U carrier must be at least 20 mm, and 25 mm is recommended. The attachment to the concrete member is done with a nut, which is screwed into a protruding rebar or rebar rod with an appropriate thread on the end face.

  Since the U carrier slot must have significant over-dimensions to the bolt terminals to compensate for tolerances, the washer or bolt / nut was rounded to ensure sufficient mounting surface It is preferable to have a band. The U carrier is pushed under the joint and screwed.

  This type of joining is specifically shown in FIGS.

  In this case, FIG. 13 shows a cross-sectional view of the wall module 2 in the vertical direction, and here a backing plate 1003 is attached. The U carrier 1004 is seen on the upper edge and the lower edge of the wall module 2, and the connection with an adjacent wall module (not shown) is performed through this. The U carrier 1004 is in contact with the edge surface of the wall module to which the U carrier 1004 belongs, and forms a spacing holder between adjacent wall modules, in other words. For reliable joining between the U carrier 1004 and the wall module 2, an end (bolt terminal) protruding from the wall member of the reinforcing bar 10 and provided with an external screw there is a length on the leg piece of the U carrier. The holes are passed through and each is fastened by a counter nut 1010 that is screwed from the outside.

  Since the diameter of the hole / long hole of the leg piece 1006 of the U carrier 1004 through which the end of the reinforcing bar 10 is passed is set to an excessively large diameter, the reinforcing bar 10 is preferable when the counter nut 1010 is loosened. Will have a corresponding play of at least 5 mm in each direction.

  The reinforcing bar 10 preferably passes through the entire wall module 2 from end to end or from terminal position to terminal position. That is, each reinforcing bar 10 has an attached joint of the above-mentioned type at both ends, and this joined body interacts with a joined body belonging to an adjacent wall module. Both joints at opposite ends of the reinforcing bar 10 are preferably of the same type and have similar dimensions. This is also true for the other joint types described below.

  FIG. 14 is a plan view of the joint between two wall modules made in this way. From the wall module itself, only a horizontal reinforcing bar 10 is visible in this simplified view. With a rebar grid made accordingly, vertical and horizontal joints between adjacent wall modules can be formed in this way.

2. Box Type Bolt Joining Box (box) type bolt joints described below are also suitable for joining in the horizontal and vertical directions. This joining type is specifically shown in FIGS.

The left half of FIG. 15 is a perspective view of a rectangular wall module 100 2 rebar grid 1012 having a box 1014 that is joined to reinforcing steel bar 10 in the end face side. The right half view, the concrete was cast, in the handover state, the wall module 100 2 is shown. Each box 1014, the wall module 100 2 box 1014 adjacent in the junction of the wall module 100 2 are joined by bolting.

16, in the two joint wall module 100 2 is a longitudinal sectional view of the box over the box combination to be joined in this manner. 17 and 18 are cross-sectional views of the cut portions indicated by Roman numerals in FIG.

On the side facing the wall module 100 2, each box 1014 is joined and fixed to an end portion of the reinforcing bar rod 10. This is done with a so-called LENTON® bolt joint 1016 or similar means. The conically tapered end of the rebar 10 that is externally threaded is then screwed into a complementary thread sleeve 1018 or bolt joint to form the overall element of the box 1014. .

  Two boxes 1014 formed in the same manner are joined to each other by joint bolts 1020 on the inside, and external bolts are provided at both ends of the bolts, and the corresponding bolt passages 1022 are passed through. The screwed counter nut 1024 acts on the annular sleeve 1028 of the associated box 1014 defining the bolt passage 1022 via the anchor plate 1026 interposed between them, and fixes the device. The end surface 1030 of each annular sleeve 1028 in this case forms a mounting surface that acts as a stopper for the anchor plate 1026 formed as a seat plate with a slit. The annular sleeves 1028 of both boxes 1014 and thus the entire boxes 1014 are thereby pressed firmly together in a clamped state.

  On the one hand, the inner diameter of the bolt passage 1022 is larger than the outer diameter of the joining bolt 1020, and on the other hand, each anchor plate 1026 has sufficient movement free space inside the enclosure formed by the wall of the box 1014, and therefore Since there is still a sufficiently large axial gap between each counter nut 1024 and its opposing screw sleeve / bolt joint 1018, a very well adaptable joint will be created. The movement free space in all three spatial directions, which occurs with the counternut 1024 not yet screwed, in this case, preferably reaches at least 5 mm.

3. Terminator type bolt connection Another connection type, which is also suitable for horizontal and vertical bonding, is illustrated in FIGS. In this case, each joined body is shown in a perspective view in FIG. 21 and in a plan view in FIG. 23 to 25 are cut views of the individual elements of the assembly.

  In this joining method, each reinforcing bar 10 of the wall module 2 is locked to a terminal plate 1034 also called a terminator on the end face side. This can be done in particular by screwing, for example using LENTON® bolted joints, where the screw sleeve 1036 or bolted joint is shape-coupled in a corresponding hole in the terminal plate 1034. It is fixed (see FIG. 24).

  The joining of the two end plates 1034 is similarly performed via screw bolts 1038, which enter the holes in the end plates 1034 and are fixed with nuts 1040. The similarly perforated steel plate 1042 between the nut 1040 and the terminal plate 1034 acts as a seat plate.

  In the embodiment, two screw bolts 1038 that are symmetrically parallel to the central axis of the reinforcing bar 10 are provided.

  In this case, what is important is the good compatibility of the joints in order to accommodate inevitable manufacturing tolerances or dimensional errors or adjustment errors as well during assembly. For this reason, if the inner diameter of the hole in the end plate 1034 through which the screw bolt 1038 is passed is made larger than the outer diameter of each screw bolt 1038 and the nut 1040 is removed or loosened, it is preferably more than 5 mm. The desired degree of freedom of movement (so-called play) in all directions is realized. This is apparent from FIGS. 24 and 25, for example.

  The length of the screw bolt 1038 is preferably set such that a sufficient gap remains between the two end plates 1034 joined together in the assembled state. Such a gap is preferably filled with a filler, such as finely divided concrete or mortar, during the production of the building synthesized from the wall module 2. This also applies to the gaps, seams, and intermediate spaces at the seam locations of adjacent wall modules in the other joint types described here.

  The spacing between adjacent parallel bars 10 in the reinforcing bar grid 1012 shown in FIG. 20 is typically on the order of 200 mm. This value applies almost to the other types of junctions described here, but of course can vary considerably depending on the application. A typical value of the diameter of the screw bolt 1038 is on the order of 20 mm or more.

4). Claw I type bolt joint This joint is somewhat similar to the U carrier type bolt joint. The joining of the reinforcing bars is not performed by a joint, but a metal claws are screwed into the ends of the reinforcing bars to ensure a perfect match. Furthermore, the metal plate is screwed into the U carrier, resulting in the shape of a rectangular ring with the carrier profile closed. For the seam between the wall modules, re-pouring is preferred.

  This is exemplarily shown in a perspective view in FIG. 26 and a sectional view in FIG.

  FIG. 27 shows a metal claw 1046 joined to each reinforcing bar 10. The claw is integrally formed, and has a screw sleeve 1048 screwed into the reinforcing bar 10 and a holding leg 1050 that is disposed at a right angle and protrudes from the side surface. Since the end of the reinforcing bar 10 with the screw sleeve 1048 is passed through a hole formed in the leg 1052 of the U carrier 1054 with a large play, the holding leg 1050 of the metal claws 1046 is attached to the U carrier 1054. Fixed inside. A metal plate 1058 screwed into the U carrier 1054 closes the U profile in a box shape.

  Similar to the U carrier type joint, the box arranged between the two wall modules 2 to be joined together preferably extends over its entire edge length.

5). Claw II type bolt joint In this joint type, similarly to the claw I type joint, the reinforcing bar 10 is screwed with a metal claw 1060 on the end side. Alternatively, the U-clip 1062 extends only on the joint itself, not on a plurality of terminals or all terminals at the side edges of each wall module 2. The fixing is performed by a bolt 1064 extending in a direction perpendicular to the longitudinal axis of the reinforcing bar 10 as shown in a perspective view in FIG. 28 and in a cross-sectional view in FIG.

6). Joining with double head anchors Finally, instead of or in addition to the joining types described so far, so-called double head anchors can be used, which are inserted into the corresponding cutouts of the wall module . This ensures the possibility of transmission of the corresponding wall joint tensile force.

  This joining system will be described with reference to a cross-sectional view of two wall modules 2 to be joined to each other as shown in FIG. In this example, two double head anchors 1070 arranged at right angles to each other are combined to form an anchor cloth 1072. In particular, the double head anchor 1070 can be firmly joined to each other at the intersection of the anchor cloths 1072. The anchor cloth 1072 can also be integrally formed. Of course, a single dual head anchor 1070 could be used instead.

  Each double head anchor 1070 has two radially projecting thick heads 1074 which are formed on the end side into anchor rods 1076, each with a corresponding notch or Fixed to the groove in a shape-coupled manner.
