Description

Adjustable formwork inner corner for large-scale formwork It is known to shape poured wall elements in a certain angle exactly that In each case certain preformed formwork devices with rigid and immovable in themselves Corner formations made and used for the individual building project. the Dimensions of the formwork and the individual corner formations are through the Dimensions of the special construction project determined. Particular caution is required when removing the formwork required because the poured EaumateriaL exerts a considerable pressure; it can Vertical shifts in the material as well as jams and cracks appear.

To avoid the disadvantages outlined, which are both technically both financially and temporally, an adjustable one, made up of several parts existing interior design that can be used in particular for large-scale formwork suggested for wall formwork.

An embodiment of the invention is illustrated in the accompanying drawings 1 - 4 shown.

Sheet 1) represents a plan view of a large-scale construction project. It several rooms are recorded schematically, their corners using the Invention to be shaken and shaped.

Sheet 2) shows an inside corner formation according to the invention in enlargement represent.

Sheet 3) shows the bracing angle.

Sheet 4) shows the individual parts of the inner corner design with stiffening brackets in the thematic order in which they are arranged one after the other.

The special feature of the invention is that the inner corner formation for wall formwork consists of two angle steels 1 + 2, e.g. of a folded Flat steel can exist. Tm are the vertex - depending on the size of the shell element - several dewinning joints 4 with lock nuts 5 arranged one above the other through which the distance of the angle 2 v) m due to the thickness of the formlining angle 1 is set. The angle 2 is made by means of a washer 6 and a wing nut 7 tightened.

Angle 1 and angle 2 have side legs, between which the laterally displaceable KAnten of the formlining are held.

The free ends of the threaded pins 4 are through the vertex t of the reinforcement bracket 3 arranged U-profiles 8 held. In the side thighs the stiffening bracket 3 elongated holes 9 are provided in which vertically arranged Bolt 10 out and depending on the distance between the edges of the formwork facing from the apex of the inner corner profile 1 and 2 are screwed tight.

The invention allows repeated use of the inner corner formation and the stiffening bracket with the associated fastening means. The device works precisely and is easy to use. It covers different room sizes and formwork elements of various thicknesses.

Claims (1)

PROTECTION CLAIM Adjustable formwork inside corner for large-scale formwork, thereby marked, that an inner corner formation, which is folded from 2 equal angles from the example Flat bars with longer side legs, with a stiffening angle by means of 2 or very well spaced threaded pins that is connected to the apex of the outer angle of the inner corner formation arranged and in a z. E.g. by means of a lock nut a determinable distance the apex of the inside angle passed through and 2nd Bp. through a U-profile al bracing brackets are held, with the threaded pins a wing nut wear, which is used to screw the outer angle in relation to the inner angle of the Inside corner formation z. For example, using a U-shaped plate and where the Side legs of the bracing bracket with elongated holes for vertical guidance arranged bolts are provided.
