facing formwork panels 37, 37 'plugged, and two new formwork panels are inserted into the upper pockets

How to get from A b b. 2 recognizes, the square tubes 10 and 10 'are above the web 24 to the Outer plates 22 welded. The lower pockets 21 can therefore remain open on both sides, see above that it is possible to place the corner bracket on two profiles lying on the floor, if, like A b b. 1 shows that a profile is placed with its end face on the flange of the other profile.

Since the corner angles are supposed to absorb the concrete pressure at the corner, the upper and lower pockets are moved as close as possible to the intersection of the legs, as can be seen from A b b. I recognize.

When building a formwork according to the invention you begin with the laying on the ground the profiles at a corner such that a profile is attached to the face of the web of the other profile and the row of holes of the attached profile is continued through a hole in the other profile. Then three bars are inserted into the two profiles, one of them exactly in the corner, the other two into the fourth or sixth hole, depending on the wall thickness. Then you put spacers on the two side bars and. Place a corner bracket on all three rods and place the two lower pockets on the bulges of the two profiles on the floor, which are then brought into an exactly right angle. Further rods are then inserted into the profiles lying on the floor, together with a number of spacers that are required for the wall height. Then the formwork panels are used next to each other or one above the other, with corner brackets being provided at the corner in each horizontal joint of two formwork panels.

When removing the formwork, the end straps of the spacers are broken off. The square tubes 10

t5 and 10 'of the corner bracket are not a hindrance, as they are welded on far enough above the web 24, as can be seen from Fig .

so in Fig. 2 one recognizes the lying on the ground Profile 30 den Bodenf].-I'ch 31 with push-through openings 32 for the rods 36, as well as the upper flange 34, in which also through openings 35 are provided for the rods.
