EP1079037B1 - Method of making a slab's edge shuttering and shuttering therefor - Google Patents

Abstract

The method involves marking out the lower edge of the ceiling to be installed later on the outer wall cladding (5). The element plates (1) are fitted to the outer wall cladding. Anchor shackles are connected to the element plates either before or after they are fitted to the outer wall cladding, with their lower bars projecting out from the element plates. An Independent claim is included for a cornice cladding to be fitted using the method.

Description

The invention relates to a method for creating a ceiling edge Abschalung according to claim 1 and a ceiling edge Abschalung according to claim 2.

Creating ceiling edge formwork over concrete Wall sections, especially over the basement area, are consuming and require a variety of Steps. Usually after the creation the concrete walls for the basement after the peeling of the Cellar ceiling with formwork panels or boards from the outside Ceiling edge shuttering created. After concreting and Curing the ceiling must be outside on the wall attached shuttering panels are removed.

From EP-A1-0927796 it is already known, with concrete element panels Ceiling edge shutters to create, and Although the concrete element panels by means of right-angled retaining clips held in an upright position and the brackets are mounted on the slab formwork. With This known formwork system can create a Ceiling edge shutter made of wood to be bypassed. she conditionally, however, that for the concrete element panels a relatively accurate contact surface is present. A such can easily be made from baking or concrete blocks created walls are generated. Cast concrete walls generally do not indicate the high accuracy the surface on to this as a support for rectangular holding elements held concrete element panels to serve.

It is also known, the ceiling edge Abschalung produce strip-shaped lightweight panels, which on the inside of the outer formwork of the concrete walls be nailed up. These plates must be partially in the protrude to be created wall to connect to the latter. Nevertheless you are inclined to Remove the formwork after casting the walls partially break or break or they keep the later load when pouring the concrete ceiling not was standing.

Object of the present invention is to provide a Method for creating a ceiling edge shuttering, and a ceiling edge Abschalung with the or on simple Proper formwork before pouring the walls can be created and which one of the quality of Surface of the wall to be created corresponding outer Surface has.

This object is achieved by a method according to the Features of claim 1 and by a Ceiling edge shuttering according to the characteristics of Patent claim 2.

The use of element plates, which means Anchor brackets firmly anchored in the underlying wall are, results in a clean and not to be damaged tilting formwork for the subsequent concreting of the Blanket. Thanks to the secure anchoring of the concrete element panels in the wall below can be on this also commercially available Euro-standard guard rail holder and secure guardrail. In In a particularly advantageous embodiment, concrete element panels with vertical holes used, through which the anchor bracket are inserted can. This allows a flawless and simple Attaching the anchor bracket to the concrete element panels.

Another advantage of the inventive ceiling edge Abschalung is that when using concrete element panels with one of the lower edge along extending stage according to EP-A1-0927796, this partial be concreted into the wall and the lower stage as Straightening measure can serve for the upper edge of the wall. One additional marking of the ceiling level is omitted.

In Figure 1 is an element plate, short plate 1 represented, which by means of nails 3 at an outer Formwork 5 is attached to a wall 8. As a plate 1 is preferably but not necessarily such with parallel to the longitudinal edges extending steps 7 and 9, which is also vertical and parallel to the having outer surface extending holes 11. Alternative to the concrete element plates described here Of course, you can also change plates 1 Building materials are used. To the horizontal Aligning the plate 1 is initially on the formwork. 5 in a known manner a horizontally extending Mark attached and then on the horizontal Marking nails or pins 13 hammered on which The plate 1 is aligned supported before it with few nails 3 is temporarily fixed to the formwork 5. The horizontal marking for the nails 13th is preferably a few centimeters below the height h, which later corresponds to the height of the ceiling of the room, appropriate. This can be achieved at Using a stepped plate 1, the level 7th within the wall 8 comes to rest and the edge on the Level 7 on the plate 1 when concreting as a standard for the height of the wall 8 can be used. Of course, in a plate 1 with rectangular cross-section whose lower edge directly as Standard for the top of the wall serve.

Before or after fixing the plates 1 to the formwork 5 anchor bracket 15 are connected to the plates 1. In the Embodiment according to Figures 1 to 4 are the Anchor bracket 15 in the holes 11 in the plates 1 of pushed down and against falling out by a Pin or nail 17, which through the top of the Plate edge 9 outstanding end of the anchor bracket 15th is pushed, secured. The anchor bracket 15 has a first straight leg 16 and at the bottom then one running in a straight line or one at an angle or offset from the surface 19 of the Shuttering panel 5 extending second leg 18. in the second leg 18 can increase the Anchoring strength holes 20 or transverse Anchor pins or rods 22 with smoother or rougher Surface be attached.

In Figure 4 it can be seen that the upper edge of the plate 1 in the manufacture of a ceiling plate 21 as a standard for the upper edge 23 can serve. Consequently, the height the plate 1 according to the thickness of the bottom plate 21, plus the width of level 7, if such is desired to choose.

In the embodiment of the invention according to FIG. 5, the Plate 1 also with nails 3 on the formwork panel. 5 attached. The anchor bracket 15 is at the back of the Plate 1 attached. The attachment can with a nail 3 or another nail. One under the plate 1 Cross-finger 4 is at least at its end preferably made of plastic.

In the embodiment according to FIG. 6, the plate 1 becomes not only held on the back of the anchor bracket 15, but the latter surrounds the upper edge of the plate. 1 hook-shaped. The hook-shaped part 25 can by a Sleeve 27 may be connected to the anchor bracket 15.

In Figure 7, the connection between the anchor bracket 15 and the plate 1 with the anchor bracket 15 or at the Plate 1 fixed webs generated.

In the embodiment of the invention according to FIG 8 takes place the anchoring of the plate 1 to a vertical Reinforcing iron 29, which is the reinforcement of the creating wall 8 is used. The anchor bracket 15 and its lower leg 18 is connected by a connecting means on Reinforcing iron 29 attached. As a connecting means can the leg 18 is split at the anchor bracket 15 in the end region be. In the gap, the reinforcing iron 29 inserted and with a wedge 35 a frictional Connection brought about. Alternatively, a can Wire tie, as he is for joining reinforcing iron serves to be used (not pictured).

After completion, i. the casting of the wall 8, can the nails 3 with a pair of pliers from the plate. 1 be pulled out, so that in the embodiments according to the figures 1 to 5 no metal parts on the Surface of the Deckenabschalung come to rest. In the Embodiment according to Figure 6 is the hook-shaped part 25 of Anchor bracket 15 is preferably made of plastic and can be separated later.
