Abstract

The invention relates to the field of construction and can be used in the manufacture of precast-monolithic floors of multi-span frame-free buildings. The purpose of the invention is to reduce the complexity of the method, improving the accuracy of installation, the strength of the block and improve the security conditions of the formwork. To do this, the concreting of the monolithic part of the floors is carried out in stages, starting from the upper floor of the building, first only the column elements are concreted along only one direction of the building axes, and then the remaining intercolumn and all intermediate elements are molded in the direction of the other axes, then the formwork is moved to another floor. The device for carrying out the method is designed as a portal 11 moving along guides 9 suspended on clamps 8 to columnar prefabricated elements 2. A jack 14 is mounted on the portal frame, abutting the center of the pallet 16 intended to form monolithic overlapping elements. 2 sec. and 1 zp f-ly. 5 il.

Claims (3)

' Claim 1. A method of manufacturing a prefabricated-monolithic overlap, including installing and securing columns of prefabricated prefabricated slabs with columns, followed by installation of intercolumn and intermediate elements, characterized in that, in order to reduce the complexity of the method, increase the accuracy of installation, the strength of the overlap and improve the safety conditions of formwork, to the prefabricated supracolumn slabs located at the same level, the movable formwork is mounted and first the intercolumn elements located 5 along only one direction her building and then formwork unfold in the direction of the other axis of the building at the same level, and the other between the tower concreted elements and all the intermediate elements overlap, after Th ¹⁰ th formwork rearrange to another floor of the building. 2. The method according to π. I, characterized in that monolithic intercolumnar and intermediate elements are, starting from the top 15th floor of the building. 3. A device for the manufacture of prefabricated monolithic floors of a building, including a pallet with sides mounted on a movable portal with rollers resting on guides mounted on 20 clamps for fastening the device to the column plate, characterized in that the portal is made in the form of a frame with diagonal braces and is equipped with a portal located in the center of the portal at the intersection of races25. an oblique jack rigidly connected to the pallet, and in the lower part of the pallet, vertical guide rods are rigidly fixed, passed through the holes formed in the diagonal braces, the portal being equipped with 30 folding suspensions at the top, and the clamps have brackets that interact with the portal suspensions. f- □ □ □ 3 /. □ □ Λ 4 f- □ □ □ / 9 □ 2 / ——- f— □ □ about FIG. 2
