Abstract

Ruppenfußsten according to 1 + 2/4 for the assembly of wall and installation block, characterized in that there are 1 + 2/11 inclined sliding surfaces 1 + 2/5 and contact surfaces 1 + 2/6 on the longitudinal ribs.

Description

I. Subject

The present product according to the invention relates to a cavity wall as well as to a production process and an assembly process.

II. Task and Effect

It should be found a dimensionally accurate production and a quick installation. The dimensional accuracy should make the costly rework unnecessary.

In addition, the usual bursting of the hollow walls should be avoided when filling the cavities when the cavity wall is completely poured in one operation.

In addition, a Maßmodulsystem should be found, which allows a production as a prefabrication without knowledge of the job site - so to speak, a principle of bricks in wall format. This would allow 100% workload for prefabrication.

Furthermore, a solution should be found that requires no elaborate connection reinforcement at the base. This connection reinforcement usually has to be tied to the existing reinforcement of the base plate and must not be displaced during concreting.

III. description

The description begins with the assembly and then goes into the production with the findings of an economical assembly. The special features are formulated in the claims.

1. Assembly

1.1 footstone

After the production of the bottom plate / foundation 2 / 1 with a triangular depression as shear gearing 2 / 2 under the outer walls for better absorption of horizontal forces 2 / 9 becomes the rib footstone 1 + 2 / 4 horizontally laid in mortar or glued gem. 1 + 2 / 1 to 3 ,

The ribstone 1 + 2 / 4 has an end rib 1 / 6 and at least one intermediate rib 1 / 10 , At the bottom there are triangular notches in the longitudinal ribs 1 / 11 , which result in shorter Fußsteinlängen as predetermined breaking points for smaller wall lengths. The end rib 1 / 12 is to be installed on wall corners. The ribbed stone allows the locally introduced concrete in the hollow core 2 / 8th between the prefabricated shells 2 / 7 direct contact to the base plate / foundation 2 / 1 + 2 aufzu take and thus remove horizontal forces in the bottom plate / foundation.

The joints of the footstones can be laid without mortar at a distance of up to 15 cm, since the smallest wall width is 30 CM. The selected distance depends on the concrete consistency to be applied, which should be stiff in the lower wall area.

Wandfuß and Fußstein have the same slope 2 / 5 and the same footprint 2 / 6 made with steel construction accuracy. This achieves a very dimensionally accurate installation of the walls 1 + 2 , This applies both to the side flight and to the upper edge of the walls. Initial tests have shown that even in wind fast assembly is possible, since even with slight contact between the wall and the footstone, a lowering of the wall with centering takes place.

The slope on the footstone can be painted with cement slurry as needed - just before the wall is moved.

This creates no static constriction at the base.

The construction control can be done with respect to the floor plans already time-saving after the laying of the Rippenfußsteine. The joints of the walls should be marked before moving the walls. This also applies to the installation block, which can also be moved later.

1.2 wall

The assembly is in an overview 8th shown. The meaning of the individual elements is attached 8th explained.

From the transport vehicle, the wall is standing in a lifting tube Fig. 9 / 1 hanged and dropped off directly at the final location. The lifting tube hangs on 2 lifting rings 9 / 3 and 2 hoisting ropes 9 / 4 , A lifting ring in the front direction is welded to the lifting tube 9 / 7 , The other lifting ring is by a spreader 9 / 2 that is welded to the lifting tube held. The hoist rope is through the in the precast shells 2 / 7 cast-in wall anchor 9 / 5 stuck, raised and placed on the footstones. Before the hoist rope is loosened and the lifting tube is pulled out, an oblique jump must be made on the first wall 8th / 2 be set and the wall are vertical. At the following walls becomes the hold of the wall head a special wall head holder - consisting of holding plate 7 / 1 with a retaining pin 7 / 2 , which leans on the inside of the precast shell, and retaining wedge 7 / 4 which is in an opening in the retaining plate 7 / 3 is inserted and then holds by striking the new wall on the wall head - introduced.

The lifting tube is pulled out after the hoist rope 7 / 4 is drained. Alternatively, a lifting tube with a Spreizzunge 7 / 6 be used. the over a rope 7 / 6 is unlocked. The expansion tongue is suspended eccentrically in the lifting tube and moves in a lower slot 7 / 9 of the lifting tube.

With a thin pull rope 7 / 6 the spreading tongue is rotated or the lifting tube pulled in here.

After all the walls have been installed, the ceilings can be laid and first the walls and then the ceilings are concreted out.

2. Production

2.1 Fußstein

The footstone 1 + 2 is produced in a folded sheet metal with various inserts up to 1.20 m. The foot formwork is about 6,0 m long and contains 5 Fußsteinlängen and can lie on a pallet laterally.

The Fußstein weighs less than a hollow block and is thus easy to handle. It contains lateral slopes 2 / 5 and a footprint for the wall 2 / 6 , The production takes place on the head, so that the floor joint can be pulled off the top and the remaining dimensions are strictly adhered to and the contact surfaces are made smooth. The ribs receive a thin reinforcing bar as a transport reinforcement.

2.2 wall

The reinforcement for the Hohlwnd 3 is prepared externally and then inserted into the wall formwork. This is a special flat lattice girder 3 / 1 with diagonal down curved end loops 3 / 2 and above 3 / 3 - in the steel mesh 3 / 4 + 8th hooked and with a retaining clip 3 / 5 spatially stabilized by lower hooks 3 / 6 and upper hooks 3 / 7 , The finished reinforcing baskets are transported to the wall formwork.

The wall formworks consist of a revolving fixed steel upper and lower frame 4 + 5 that have open joints 4 / 4 connected to each other. First, the upper frame is filled with concrete; after its hardening, the subframe is then filled with concrete and the upper frame is folded onto the subframe. These formworks are suitable for pallet and web production. It is also possible to use these formwork as a separate tilting pallet. Then holding tubes are applied to the upper frame to keep the precast shell stable in the upper frame. The open joints also allow other techniques to exploit the concreting surfaces. With standard formwork, wall widths of up to 2.50 m and wall heights of up to 3.60 m can be produced. Other dimensions are possible.

The wall thicknesses are met by the steel construction of the frame and joints to 1/10 mm and are therefore sufficiently accurate for the concrete.

On the wall foot side is a trapezoidal profile 4 + 5 / 9 for the production of the lower wall slope for adaptation to the Fußstein. This trapezoidal profile is held by a U-profile as Justierprofil 5 / 10 and over an anchor angle 5 / 11 on the upper frame by means of a clamping wedge 5 / 14 drawn. The anchor angles 5 / 11 have a recess for this purpose 5 / 12 into which the clamping wedge 5 / 14 is plugged and taken. After hardening of both prefabricated shells, the clamping wedge is beaten in the opposite direction so that the upper frame is turned and the hollow wall element becomes free.

The sponge wedge lays against a split clamping angle 5 / 13 that is attached to the top frame 4 / 1 is welded. The altitude of the clamping position angle is chosen so that the contact pressure over a Ausmitte 5 / 16 in particular to the joint between the lower edge of the trapezoidal profile 5 / 9 and upper frame 4 / 1 acts. This gap is thus tight.

When stripping the hardened wall of the clamping wedge 5 / 14 solved and then the top frame 4 / 1 folded. Now the trapezoidal profile 5 / 9 be pulled out and the finished cavity wall may be driven by means of a forklift with suction cup lift arm on the storage space. Due to the low weight up to approx. 1.0 t the transport is very fast.

The longitudinal and transverse members 4 / 5 to 8th Beyond end tabs and screws with the top and bottom frames 4 / 1 + 2 connected in predetermined threaded holes such that the Maßmodulsystem arises from it as planned.

For intermediate dimensions, there are long holes in the end tabs for adjustment. Thus, other dimensions can be made.

The measurement module system 6 is based on the usual planning parameters. It contains a width grid of 30 cm.

The height grid contains all known dimensions and intermediate dimensions.

The wall widths are produced by default in an interval of 10 cm. In addition, a joint parameter was introduced with variable width up to 3 cm. Measurements on various construction sites have determined that the locally introduced concrete does not escape up to a joint width of 3 cm. This means that with 3 joints each floor plan dimension can be created without having previously known the floor plan. The turning process can be carried out by means of additional hydraulics or with a crane, which can also be mounted on a concrete distributor. In addition, through the open joints, other turning and turning forms are possible to allow an opotimale utilization of the concreting surfaces. Upper frame and subframe can z. B. also at different locations before the sub-frame is loaded.

With the standard formwork wall thicknesses up to 60 cm can be executed.

The trapezoidal profile can also be attached to each pallet, so that other dimensions can be made without special formwork frames. The assembly process is not affected.

IV. Use

The use of the MABAU WALL can be done for all types of buildings. This also applies to skyscrapers over 40 m in height. Furthermore, this wall can be used in swimming pools and angle retaining walls as well as in basements. In addition, a use in folding is possible for. In shed roofs. In urban civil engineering, an application is advantageous because before the Betonverguss already a backup of the surrounding soil is done and the walls are already sustainable as formwork. There is no formwork to be pulled.
