Description

The invention relates to the construction and can be used to erect a building, mainly with massive walls and to block them. with fixed formwork and continuous lifting of structures due to the pressure of the concrete mixture injected into the closed formwork cavity, control and adjusting the direction of travel of the structure 1.

The disadvantage of this method is that it cannot be used for erecting buildings with relatively thin walls and columns, since in this case the frictional forces of the formwork on concrete surfaces exceed the magnitude of the pressure generated by the pressures (elastic concrete mix formwork.

The purpose of the invention is to expand the technological capabilities of the method.

The goal is achieved in that according to the method of erection of a monolithic reinforced concrete building, which includes laying the foundation, mounting and fixing it on the foundation (vertical formwork coping, Continuous concreting of vertical structures with fixed formwork and continuous lifting of structures due to the pressure of the concrete mixture pumped into the closed cavity formwork, control and adjustment of the direction of movement of the structure, along with the foundation device, install the floor of the building, simultaneously enno and concreting the upper tier vertical structures concreted floor slab overlap, that after the concrete sets tear strength calculated from the floor, and in the resulting space: GUSTs between the floor and the floor slab pumped compressed air.

FIG. 1 shows a fragment of a building with a foundation, mounted on it by formwork and a floor, a section; in fig. 2 - the same, with the upper brown of the external walls and internal supporting structures (walls, columns) concreted in the formwork, on the floor - with the building overlapping; in fig. 3 - concreted elements, cut off from the formwork and the floor; in fig. 4 - erected building.

The building is erected in the following sequence.

Prior to the commencement of the main work on the construction site, the trenches for the foundation of the outer and inner walls and the excavations for the uncoupled columns are torn off;

such as those under the bethoencruct project and fuidaments under its walls 1 and columns 2, forming the cavities of the formwork (matrix) 3 in them, slightly expanding upward, with vertical walls 4 and semi-cylindrical (, columns of columns) 5. When erecting foundations for external walls in them, ystap ffiayu1 shshi for jacks 6 and tap-off units 7. Then the foundation is concreted under floors 8, external vertical shields of cladding 9 of outer walls are installed and attached to the foundations, mounting tap-off units 10 and b Rab 12 with braking devices. In the niches 6 on the floor near the columns and along the internal walls, jacks 13 are mounted, while the jacks installed along the walls and near the columns are equipped with devices that prevent air leakage when it is forced under the ceiling and allow them to be quickly removed from the floors. All jacks are connected to the hydraulic pump by hydraulic lines (not shown). Concrete bridges 14 and concrete pumps 15 are mounted, air ducts 16 and compressor P. The bases are covered with lubricant under the floors, and the concrete walls and bottom of the formwork are plastered with a cheap matrix with a low coefficient of friction on concrete (for example, polyethylene film) or painted with a composition having similar properties.

After that, the armature of the upper part of the walls 18 and the floors 19 (Fig. 2) are mounted in the cavity of the formwork and on the floor of the building.

Laying the concrete mix into the walls is carried out by a concrete pump 15 through the beate water supply 14, and into the ceiling by any known means. After the concrete mixture is laid, a technological break is required, which is necessary for the concrete to gain strength, sufficient to continue the subsequent operands on the construction of the building.

After the concrete has hardened, the zabomeronak constructions with the help of jacks 13 are detached from the formwork and the floor (FPG. 3), concrete is pumped into the cavities B of the formwork 20, and air is injected into the space of the MS.

Under the action of the forces created by the pressure of concrete (30-35 kg / cm) and air (by calculation), the building is raised to the design marks, continuously forcing the concrete mix and air (Fig. 4). After this, the air pressure is maintained until concrete is installed in the lower zone of the formwork with the calculated strength, then the equipment and the formwork shields are dismantled.

The economical technique of the efficiency of the proposed method lies in the fact that it allows to expand the technological possibilities; 1, the construction of vertical structures to the erection of any height, and the efficiency of the method during the height: “p.
