SU1574768A1 - Device for errecting unloading superstructure under building - Google Patents

Abstract

The invention relates to the construction and can be used in the superstructure industrial and civil buildings. The aim of the invention is to reduce the time of construction of the superstructure. For this, a sectional platform 2 with an elevation drive 26 of sliding formwork mounted on it is supported on the existing walls 1 of the building. The concreting of the columns 16 is carried out by moving the formwork with chains. At the same time, simultaneously with the erection of the columns on the platform 2, the girders are concreted with their subsequent resting on the erected columns and thus creating the supporting framework over the existing structure. 1 hp f-ly, 7 ill.

The invention relates to the construction of can be used in the construction of non-load superstructures over existing buildings, such as the reconstruction and expansion of industrial enterprises and with an increase in the living area of cities in built-up areas.

The aim of the invention is to reduce the time of erection of the superstructure.

Pa figs. Figure 1 shows schematically the supervised formwork, which consists of a lebelka 27 driven by an engine 28 and measuring gears 29. There are sprockets 31 on the shaft 30. On which are put on chains 25. The second ends of the chains are fixed on the platform- 5 form 2.

The device works as follows.

During the preparation of platforms 2, reinforcing-shuttering blocks of girders 32 and drives 26 for raising sliding are mounted on them

The building is designed with its formwork installed. After this, the platform 2 was installed with sectional platforms, a section, and the walls of the building and with the help of the figs. 2 - - the same plan view; in fig. 3-t, 21 install shields 17 and 18, a sliding-section platform, a slit; in fig. 4 - lifting unit for sliding formwork of columns; in fig. 5 - the same plan view; in fig. 6 - sliding formwork of columns; in fig. 7 - de-fastening the formwork panels with the frame of the working platform (rotated by 580 °). On the longitudinal walls 1 of the superstructure building, a platform 2 is installed of the longitudinal 3, transverse console beams 4, 20 links 5 and poles 6. On the uprights 6 there are fastened screw pairs that ensure accurate installation of the platforms vertically and consist of nuts 7 and screws 8 ending in at the bottom of p. 9 with base plate 10, fitted with brackets, 11 flocks 12dl, gripping 25 walls I.

for formwork in the design position. Then the columns 6 are bztonirovanny, moving the sliding formwork with the help of chains 25 of the drive 26, the ends of which are fixed on the working platforms 9 of the formwork. The concreting of the bolts 32 is performed simultaneously with the erection of the columns, then these structures are combined, and platform 2 is dismantled. After hardening, they are mounted on columns, and platform 2 is dismantled.
