SU372334A1 - METHOD OF CONSTRUCTION OF MONOLITHIC BUILDINGS AND CONSTRUCTIONS - Google Patents

Description

The invention relates to the technology of building production and can be used when erecting buildings and structures from monolithic reinforced concrete with intermediate floors in the sliding formwork. There is a known method of erecting monolithic buildings and structures with self-supporting walls in a sliding formwork with simultaneous concreting of walls and floors. The disadvantages of this method are the loss of time caused by the need to raise the formwork idling and stop it for concrete to gain the necessary strength before the concrete begins to concrete on each floor. The purpose of the inventions is to speed up the construction process and ensure the rigidity of the formwork. To do this, the self-supporting walls are concreted continuously until the lower edge of the inner panels of the sliding formwork rises to the top level of the ceiling. FIG. 1 shows the erected building; on 1FIG. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one; in fig. 4 - bearing wall when it is concreted after installation of the formwork and reinforcement bars; in fig. 5 - bearing wall when concreting overlapping. The method of erecting monolithic buildings and structures is as follows: concreting of walls / and 2 in the sliding formwork is carried out to the mark of the bottom of the floor slab 3, after which plugs 4 are installed in the form forms, which cut off the sections of the bearing walls 1 on which the slabs 5 rest, continue the concreting of all self-supporting walls 2, including the intersection angles of the walls. The sliding formwork is raised until gaps 6 are formed between the bottom of the formwork shield 7 and the top of the concreted support wall 1 required for the overlap device 5, which is integrally connected to the support wall. After the shutdown of the formwork, the shields of the working floor 8 are rotated, installed vertically, and work is performed on the installation of formwork 9 and shutoff valves. After that, the shields of the working floor 8 are rotated to a horizontal working position, the slides 4 are removed and the load-bearing walls are concrete / to the level of previously concreted self-supporting walls 2. Then the working floor shields are re-installed in a vertical position and the concrete is concrete 5. walls to the bottom of the next level overlap. The cycle is repeated.

Subject invention

The way of erecting monolithic buildings and structures with self-drying, their walls in a sliding formwork with simultaneous concreting of walls and floors, characterized in

that, in order to speed up the process of erection and ensure the rigidity of the formwork, the self-supporting walls are concreted continuously until the lower edge of the inner panels of the sliding formwork rises to the top of the ceiling.
