Abstract

FIELD: construction.

SUBSTANCE: at the first stage of erection, external and internal panels of leave-in-place form are installed, and in areas where vertical reinforcement rods or vertical anchors installed in foundation come out, reinforcement frame is placed, and extensible shaping facility is installed to embrace the latter in the form of hollow volume trihedral rod, which is temporarily fixed by its larger face to internal surface of form panel, and sheets of heat insulation materials are attached to two other faces of rod and are fixed by their free ends to internal side of leave-in-place form. Then concrete mass is poured into rod, and as concrete gains in strength, rod is released from temporary fixation and is extended to design height till final erection of support pillar with repetition of the first stage operations cycle, after erection of support pillar till design height, hollow volume trihedral rod is withdrawn from form, and panels of leave-in-place form are fully filled with concrete mass till its final hardening.

EFFECT: possibility to operate building with increased load over its slab.

Description

The invention relates to construction and can be used in the construction of monolithic walls, ceilings and partitions of buildings used in various industries.

A known method of concreting monolithic walls, including the installation of an internal rigid formwork, a concrete concreting grid, while concreting additionally install an external rigid formwork for a decorative finishing layer and an additional restrictive grid near the internal rigid formwork at a distance of the finishing layer, and concreting is carried out with plastic concrete supplied between restrictive grids (SU 1560706, Е04G 9/10, 04/30/90).

The disadvantage of this method of concreting monolithic walls is that it represents excessive material consumption and the complexity of its implementation.

The closest technical solution is a method and device for erecting walls of buildings and structures, including a frame for attaching formwork from removable or non-removable cladding, the internal space of which, after mounting the frame and installing it in the design position, is filled with hardening solution, while the frame is made in the form of a cellular spatial lattice structure of frames connected by jumpers using one-piece joints, and porous concrete / RU 47935 U1, Е04G 11/10, is used as a hardening mortar, September 10, 2005 /.

The disadvantage of this method and device for its implementation is that it is unnecessarily material-intensive and time-consuming and, in addition, it does not provide for the possibility of operating a building or structure with additional loads on it.

The technical task of this invention is that during the construction of low-rise monolithic buildings or structures, it provides the possibility of operating a building with increased load on its overlap.

The technical problem of the described method is ensured by the fact that the method of erecting structures of buildings and structures, characterized in that at the first stage of erection, external and internal panels of fixed formwork are installed and a reinforcing cage is placed at the exit points of vertical reinforcing rods or vertical anchors installed in the foundation and installed in girth the latter a retractable molding tool in the form of a hollow volumetric trihedral rod, which is temporarily attached to the inner surface with a larger face panels of fixed formwork, and sheets of heat-insulating material are installed on the two other sides of the core, which are fixed to the inside of the fixed formwork with free ends, then the concrete mass is poured into the core and after the concrete has set strength, the core is freed from temporary fastening and extended to the design height until final construction the support column with the repetition of the work cycle of the first stage, after the support column is raised to the design height, the hollow volumetric trihedral rod is removed from the opal CHB and shields permanent formwork completely filled with concrete mass before its final curing.

The method of erecting a monolithic structure of buildings and structures is illustrated by drawings, where in Fig.1 shows a General view of the formwork, top view; figure 2 is the same side view; figure 3 shows a General view of monolithic formwork, top view; figure 4 is the same side view.

The fixed formwork contains fixed panels 1, a retractable molding tool in the form of a hollow three-sided rod 2, which is temporarily attached with screws 4 to the inner surface of the panel 1 of the fixed formwork with a larger face 3, sheets of heat-insulating material 5 are mounted to the other two sides of the rod, which are attached with free ends to the mounting foam 6 to the inner side of the shield 1 fixed formwork. Between themselves, sheets 5 of thermal insulation material are also fastened with mounting foam 6. Boards 1 are installed on the foundation 7, made with vertical anchors 8, and fastened together with screeds 9. At the end of the main type of work, formwork is filled with monolithic concrete 10, and inside the formwork boards form a support column eleven.

The method of construction of a monolithic structure of buildings and structures is as follows.

At the first stage of the fixed fixed formwork, the hollow volumetric forming rod is installed in the places where the vertical reinforcing ties (rods) or installed vertical anchors exit, so that the reinforcing ties or installed vertical anchors are located on the foundation inside the rod, temporarily screw the trihedral rod with screws to the inside the surface of the fixed formwork, sheets of heat-insulating material are installed on the two other sides of the molding core, preferably but expandable polystyrene and fixed to the inner side of the permanent shuttering and between a mounting foam.

The height of the molding core is determined by the installation and laying of the gypsum concrete mixture. After the construction of a structure of a certain predetermined height, the molding rod is freed from temporary fastening and lifted up so that its lower part is at the top, excluding the flow of the mixture into the molded space. Next, install the rod and temporarily attach it to the inner row of fixed formwork of the next row in height. After reaching the design height of the wall, the hollow three-dimensional molding core is freed from temporary fastening and removed from the molded space, a reinforcing cage is installed, which in turn is connected with the reinforced frame of the interfloor grillage.

After laying the concrete and gaining its strength, a supporting reinforced concrete spatial structure is formed inside the core of the heat-insulating monolithic pouring from the heat-insulating material D- (250-300), B-0.75.
