Procedure for erecting a structure

The invention relates generally to construction and is more particularly directed to building construction for manufacture of office and other buildings using pre-formed concrete components.

The building construction method described here has long been known in the construction industry. A large number of processes are already known and attempts for the construction of structures, which, however, differ considerably from each other.

Because of the rising wage and labor costs in the construction industry Recent attempts have focused on preforming as many components as possible in the factory so that they can then could be erected on the construction site using only a few trained construction workers, such as bricklayers, etc.

In connection with this, it is also known to pre-cast floor slabs. At the moment, however, weight and space requirements have limited the extent to which such pre-cast components can be made can use. The weight is in this context

109830/1315

not only important from a transport point of view, but also of importance in terms of ease of erection and handling at the construction site.

Thus, it is an indispensable requirement for the use of pre-cast components that these components without Extraordinary effort and expensive equipment can be erected and assembled.

For this purpose, the construction techniques at the present time often also include the pouring or erection of the vertical walls at the construction site. The walls then take preformed bottom parts that are only partially cast in terms of their thickness. If these floor panels then on the construction site are in place, the rest of the soil is poured, so that the finished product is completed will.

During this procedure-to a technical port step led, it remains difficult to connect the floors with the vertical walls and it is also with the known ones Procedure impossible to build several floors before potting.

It has now been ascertained that all essential components for the construction are pre-cast before being transported to the construction site can be and that they can then be erected on the building site, whereupon you then pour in such a way that wall and floor components connected or "fused" together will.

For this purpose, a standard wall plate with a row formed by vertical cavities, the cavities having the dual purpose of lightening the weight of the pre-cast component for purposes of transport and erection and at the same time the purpose of creating recesses serves, in which the prefabricated concrete used at the construction site can be included, so that it actually there is a close connection between the wall and floor components after pouring at the construction site.

109830/1315

It has also been found that when you attach the wall components with suitable horizontal undercuts their lower edge provides, which are in connection with the vertical cavities, several floors are built before you start pouring.

These undercuts bridge longitudinal ribs on the floor construction panels, so that after the final pouring of the concrete through the cavities provided by these undercuts can flow through and thus into the vertical cavities that are connected to them. With this arrangement The precast concrete not only covers the surface of the floor slab to the desired height, but it is also located in the vertical cavities of the wall panel, so that the wall panel and floor panels are connected to each other by w are connected or "fused" to the same precast concrete.

In a further embodiment of the invention, it is proposed to use mechanical auxiliary fastening elements between the components just described in order to ensure the strength before the time of the final potting. This HilfsbefeBtigungseinrichtungen suitably have the form of bent rods, which are supported by the soil components and can be respective plates on the walls by connecting fieftschweißung *, so that a displacement of the floor panels and wall panels prevent JL is. At the same time, they serve as reinforcement members after the precast concrete has been poured.

The object of the invention is therefore the implementation of a construction technique using the measures specified above together with other measures that result from the following description.

If when using the method according to the invention various special structural requirements arise, for example where corresponding short or longer clamping ■ · occur widely, it may be desirable to

109830/1315

Plate either by pre-stretching or by special reinforcing devices, such as bars o. The like. To reinforce the provide support against tertiary deflections during use of the building.

Ss has been found in the work on which the invention is based that you can achieve a base plate with significantly improved strength properties if you have a cheap bridge construction together with partially cast Sheets of the type described above are used. In practice one uses a pair of rods, one on top of the other Allocating surfaces are connected with punched sheet metal parts, so that a mast-like carrier is formed, which is in Extends the longitudinal direction of the base plate and is partially embedded in it during the initial potting.

The stability is achieved in this case by using cross bars, which are arranged on the top and bottom are that they themselves provide a Bechteck, a larger one Has resistance to lateral shear forces. By making openings in the opposite bridge elements provides, there is, as already explained, a particularly easy installation option for the usual supply lines, which is of great advantage because you in particular simple way an electrical or installation line through the openings in the rack frame before the final Potting can introduce.

It can also be seen that when using this steel bridge-like Component for the one-piece hip a greater productivity can be achieved due to the fact that the settling time, froze, which you can pull off the forms, is significantly reduced.

According to the drawings and especially after Pig. 1, the improved construction includes the use of a pre-cast wall made of one or more pre-cast wall panels 10 together with a plurality of identical floor panels 20, wherein
each wall panel 10 is vertical, while the floor panels bridge the distances between adjacent wall panels 10,

109830/1315 -7-

so that a floor and a ceiling for adjacent floors of the building to be erected arise.

How to get out of Pig. 1 recognizes the wall plate is generally Sechteekiggin the front view and contains a upper edge surface 10, a lower edge surface 12 and opposite plane. Visible areas "13 and 14. In accordance with known construction methods, the length of the wall panel 10 is an even multiple of the width of the floor panels 20, so that a A given number of floor panels can be placed in alignment with one another on the upper edge surface 11 of a single wall panel 10. This is done in practice, for example in that the wall panel 10 is approximately 720 cm (24 feet) long and 240 cm (8 feet) high and 16 to 25.4 cm (6 to 10 inches) Jk is thick and accommodates six 4 feet (120 cm) wide floor slabs ^ that can vary in length. Ss is however it goes without saying that the invention is not limited to any particular dimensions and that therefore the particular numbers en are given for illustration purposes only.

As can be seen in particular on FIGS. 1, 2, 3 and 4, the wall panels 10 have a plurality of vertical hollow channels 15 which are arranged at the same distance between the opposing planes of visible surfaces 13 and 14 and are located between the upper edge surface 11 and the lower edge surface 12 of the plate 'extend. These cavities 15 have a double purpose, because first of all they significantly reduce the M weight of the slab in question and, secondly, can then be filled with concrete during the Schlußvergießvorgangee so that there is a good connection of the floor and wall slabs after the erection of the building .

The preferred embodiment form according to the invention, like them hler is described in detail using an example, also includes the installation of additional floors in front of the ' final grouting of the floor just formed. In this respect, for example, the team erecting the wall panels and laying the floor panels can have two

-8-109830 / 1318

or build several floors before the concrete pouring Team starts.

Accordingly, a series of horizontal transverse grooves 16 and 16a are provided in the lower edge surface 12 of the wall panel 10, the extend transversely through the wall 10 between the visible surface 13 and the visible surface 14. In the preferred reproduced Embodiment, the transverse grooves 16 have a greater depth than the transverse grooves 16a, which can be seen most clearly from the lower Part of Fig. 1 can be seen. It should be noted that the transverse grooves 16 and 16a in their total number of the number of Corresponding to cavities 15 and that furthermore the transverse grooves are vertically aligned with the cavities.

From Pig. 1 it can be seen that the floor panels 20 in their construction are identical. These floor panels are pre-cast in a rectangular shape so that they have a base part 20a, a longitudinal edge part 21 and a series of upwardly projecting ribs 22 and 22a. The ribs 22 extend over the entire longitudinal extension of the plate 20, so that their ends cut off with the longitudinal edge portion 21 of the plate. The ribs 22 end on the other hand shortly before the longitudinal edge part 21. The purpose of this measure will be explained in more detail later. Besides that Conventional reinforcement bars 40 extend longitudinally the bottom plate 20.

For the connection of the floor panels with the wall panels as a preparatory work before the final pouring is necessary recognizable several alternatives »

First, the components can be provided with tack plates 41 and 42, as can be welded together at the construction site. Besides that or alternatively, a row of rods 43 bent at right angles can loosely be put in the position according to FIG. 1 the weight of these links holding them in place until the time the potting process is completed is, in which case the members 43 serve as reinforcement units. Finally and in the event that it is desired is to assemble several floors beforehand and so that a certain strength is required, one can use a

109830/1315

" ⁹ " 210 I 084

Establish a stronger connection by welding Components are used that mechanically connect the floor and wall panels together.

From the Pig. 3 and 4 it can be seen that the ribs 22 with metal insert plates 23 are provided, which are arranged at a distance inside from the outer ends of the floor panels. The two As can be seen most clearly from FIG. 4, insert plates are each attached to the hip.

These insert plates 23 serve as a fastening point for certain, preferably rod-shaped connecting elements 24,

25, 26 and 27. Elements 24 and 25 are at right angles curved metal rods which abut against opposite wall parts of the cavities 15, as can be seen most clearly from fig. 3 can recognize. As a result of this arrangement, the base plate 20 is prevented from being displaced longitudinally with respect to the wall plate 10 locked in their place once the components are fastened in place, as can be seen from fig. 3 recognizes, for example by using a spot weld on the insert plates 23. It can also be seen that the insert plates 23 can be cast, but can also be used, for example can be fastened by screws or other fasteners. The rods that serve as connecting elements

26, 27 are straight bars and extend from one edge

the plate 20 for connection to the rod extending in the same direction φ for alignment and connection purposes. Such a connection then prevents vertical or transverse displacement of the floor panels.

Once the floor panels are fully installed, as is the top of the pig. 1 shows, it goes without saying that you put another wall panel on the floor panels 20 and thus with the construction of another Floor can begin. The ribs 22 and the rod-shaped connecting elements 24, 25t 26 and 27 are in the of the Groove 16 formed cavity received, so that the bottom surface 12 freely on the upper edge parts of the floor panels sits, as can be seen from the lower part of FIG

109830/1315 ~ ¹ ° -

leaves. While the ribs 22 are seated in the grooves 16, the ribs 22a push in front of the flat visible surfaces 13 and 14, if the plate is inserted. Another setting can be achieved by using centering pins 31 in the upper and lower edge surfaces 11 and 12 of the wall plate 10. The pins 21 prevent longitudinal or transverse displacement of the unit while the stop of the ribs 22a on the visible surfaces 13 and 14 of the wall panel 10 provides further support against transverse displacement supplies.

The pen used is preferably one Cone pin which is inserted in the cone tube 32, which extends in the vertical direction and into the edge surfaces 11 or 12 of the wall plate 10 opens. According to the drawing, the pen and tube are relatively short, they can be connected however, they can also extend over any desired length in order to further stabilize the structure before the final potting to ensure, if so desired.

When a wall panel 10 is placed on the laid floor panels, as shown in the lower part of FIG. 1, you only need the concrete up to the height "L" Pig. 1 of the drawings. During this pouring, the concrete penetrates through the transverse grooves 16 and 16a and arrives thus in the vertical cavities 15 whereby gravity ensures that the cavities 15 are completely filled which leads to a complete connection of the wall and base plate through this casting process.

It goes without saying that it is easy to open the relevant supply lines or openings prior to this potting the top of the built-in floor panel 20 because all electrical and other outlets are prior to completion the final potting should be appropriate.

In this regard it should also be pointed out that the finished floor level, which is indicated by the line "L", sits above the uppermost surface of the grooves 16 or 16a, so that after complete potting there is no trace of the grooves

-11- 109830/1315

21 O 1084

and 16a remains, which are completely covered by the potting process. If the floor and wall components are in the flat are assembled in the manner described, it goes without saying that corridor walls and other inner walls can be easily built can build using known techniques.

Also with regard to the casting can be different Think of alternatives depending on the strength requirements. For example, a solid concrete cast near the joints may be required with the wall panels, while the intermediate part of the floor panels remain with cavities which can be created by laying a plate or wire mesh over the top surfaces of the ribs. A honeycomb-like arrangement can also be used if necessary provide.

It can also be seen that when building several floors before the final grouting, some additional reinforcements may be required. In this case it is possible to use the corridor walls that are perpendicular to the wall panels 10 run before installing the next base plate 20. Also an X-shaped bracing or similar devices, to increase strength can be used if necessary.

On the other hand, if each tier is to receive the final grout before the next tier is installed, then the sawtooth ¹¹ bottom edge of the panels 10 can be eliminated by eliminating the grooves 16 and 16a The foundation (not shown) is erected and the floor slabs are set in place. Then the final pouring of the concrete takes place in such a way that a one-piece continuous structure is created. Then the second row of wall slabs is erected * and the process can be repeated for the next floor.

In the following, a modified embodiment of the invention will be explained with reference to FIGS. Each improved Contains building board 110, as can be seen in particular from FIG

can, a base part 111 and a number of them in the longitudinal direction extending, partially embedded connecting members 112, which are longitudinally of the plate and substantially run parallel to one another, as best shown in FIGS. 7 and 8 of the drawing.

In addition, the core 116 is each link 112 tack welded to transverse reinforcement bars 113, while similar reinforcement bars 114 are tack welded extend to the links 112 and on their surfaces are connected by tack welding, as can be seen in particular in FIG. 7.

7, 8 and 9, the individual connecting links 112 are identical in shape and contain a tubular one Frame member 115 »an elongated solid core 116 and each other opposite sheet metal side plates 117 and 118, all of these components being welded to one another, which is achieved by the welds 119 is indicated.

The side plates 117 and 118 are preferably identical and have a rectangular shape, wherein opposite end portions 117a, 118a are provided with the opposite to each other top and bottom pieces 117b, 117c and 118b, respectively, 118c are connected. These top and bottom pieces are connected by cross members 117d, 118d that are X-shaped and bridge the distance between the floor and upper pieces, so that a kind of truss is created, which has a high strength having.

In this embodiment of the invention the upper one is tubular Frame member 115 is a hollow body, while the lower corresponding frame member or core 116 is a solid core, with which one can exert a preload when this core is inserted into the base part during construction.

The reason for this construction is that the finished building board 110 is under pressure on its top and on its Underside is put under tension when applied to it laat will. The solid lower core 116 resists, ug benppr,

1 0 9 H '^; ι ' ¹ / s ■' ^c

while the hollow tubular frame member 115 has this capability not required.

From FIGS. 10 and 11 it can be seen that one or more the reinforcement rods 113 extend over the edge of the plate so that the outer part can be bent up, as indicated by the upturned portion 113a in Figures 10 and 11 of the drawings. With this arrangement, a endless metal loop 120 are pushed over the adjacent ends 113a of adjacent plates 110 whereupon this bends back down into the dashed position according to FIG. 10, whereby they pull against each other and a longitudinal stop adjacent plate links is achieved.

In a similar way, as FIG. 7 shows, U-bends 121, 121a are placed on the separated ends of the connecting links 112 of adjacent building boards 110 and welded or attach toggle assemblies or fasteners together so that the links are in place are held, as Fig. 7 indicates. If necessary you can bend the Ü-arcs downwards at right angles so that they are against the walls of the cavities 125a create, which are provided in the vertical wall plate 125. This fastening method can be clearly seen Fig. 1 to 6 and it can also be seen that this method is also possible in the other embodiment.

A series of connectors or trusses are used in making the improved wall panels 112 that are of the appropriate length and height. You then only need to insert them in the appropriate form that is suitable for casting of the base 111 is used, the core 116 optionally being pretensioned.

When the building board is poured up to the level "L", then you only need to have them removed. After hardening, the mold can be removed and removed the building board for transport to the construction site. Ee should be noted that the rods 113 and

-14- 109830/1318

held in place by tack welding to a truss construction that is put in place on the construction site before pouring. Furthermore is still once to remember that several of the lower reinforcement bars at 113 in the vertical position of FIG. 10 can be placed high.

After the building panels have been manufactured in this way, they can be stacked on top of each other for transport to the construction site. At the Construction site, it is only necessary that a crane or other device with its hook or sling through one or more of the links 112 is guided, whereupon the plate lift in place and onto a vertical wall 125 can be abpetaen, as FIG. 7 shows. Further plates 110 are then used, which are connected to one another at their two ends, as already explained. In this regard, a side connection can also be made by inserting the loop 120 in the position shown in FIG and then the bent-up parts 113 are bent over into the position shown in phantom in FIG.

Regarding the adjustment of the panels 110 on the wall the ends of the units are adjusted so that they lie over the cavities 125a, as can also be seen in FIG. The connecting devices in the form of U-bends 121 and 121a are then used to connect the individual plate members to manufacture.

Now the corresponding supply lines are laid, whereupon one pours up to level F according to FIG. Included the concrete not only covers the plate 10, but the concrete also enters the cavities 125a, so that a unified structure is created.
