Abstract

The invention relates to construction. The goal is to reduce labor costs for formwork work and increase the technology of formwork. The formwork contains a beam 1, shields 4 hinged to it, racks 5 with jacks. Racks 5 are rigidly attached to beam 1. The device for demolding contains guides 8 with stops 9 and a slider 10 with thrusts and slings 12 mounted on guides 8. When slinging the formwork with a crane for slings 12, the slider 10 moves up and acts through on the struts in the form of lever pairs 6 and 7, which, having broken out on axis 14. tear off the shields 4 from the concrete. The slider 10 is moved to those x (yur, until the shields 4 are in a vertical position. 4 Il.

The invention relates to construction and can be used in the construction of buildings with monolithic slabs.

The purpose of the invention is to reduce labor costs for onalubochny work and improve the manufacturability of formwork.

FIG. 1 shows a formwork for concreting a monolithic slab, general view; in fig. 2 - the same, after stripping; in fig. 3 is a view A of FIG. one; on f | ig. 4 shows a section BB in FIG. 3

The formwork for concreting monolithic slab contains beam 1 with holes 2 and loops 3, formwork boards 4 pivotally attached to it, jack stands 5, struts in the form of lever bunk 6 and 7, and a device for stripping.

Racks 5 with jacks (not shown) are rigidly attached to the beam 1.

The device for stripping includes guides 8 with stops 9 and a slider 10 with thrusts 11 and straps 12 mounted on guides 8 fixed on racks 5 by means of grippers 13.

The struts in the form of a lever pair b and 7 with a common axis 14 are hingedly attached to the end of the formwork boards 4 and to the uprights 5 in the lower part.

Ti gi 11 are hinged to the slide 10 and to the struts 6 and 7 on the axis 14.

Using formwork for concreting monolithic floor work as follows.

With the formwork for loops 3, beams 1 of the slider 10, shuffling down along the guides 9, acting with steps 11 on the common axis 14 of the lever pair 6 and 7 of the struts, causes the formwork boards 4 to be horizontal. In this case, the lever pairs 6 and 7 should be located on the same line and their position is fixed by the stop 9, which prevents further

move the slider I). The formwork is then installed in its working position and retracted by jacks (not shown) of the racks 5.

After the installation of the formwork, the reinforcement is laid and the concrete is concreted. After the concrete has reached the blocking strength, the formwork is dismantled.

For this, the formwork is attached to the lines by the crane 12 and is lifted. In this case, the slider 10 moves upwards and acts, by means of tams 11, on the struts in the form of lever pairs 6 and 7, which, being pulled out on the axis 14, tear off the shields from the concrete.

Next, move the slider 10 until the formwork boards are lowered into the vertical position. In this position, the formwork is removed through the slit formed in the ceiling beam 1.
