Description

The invention relates to the construction of prefabricated buildings in which columns are used with consoles bearing a non-opening, and consists in the fact that the columns are interconnected by means of horizontal frames reinforced with their corners at the ends of the cantilevers. Beam-shaped beams, on which the roof elements are supported, can be laid on the columns.

In FIG. 1 shows an exemplary embodiment of a reinforced concrete building according to the invention in vertical section; FIG. 2 - horizontal section - bottom view; FIG. 3 shows the layout of the frames, beams and base plates; FIG. 4 is a diagram of the assembly sequence of the precast ceiling; FIG. 5-connection of beams, with a column; FIG. 6 - roof plan; FIG. 7 are components of a prefabricated building; and FIG. 8 is a diagram of the structure in plan, with a considerable distance between the columns.

In the example shown in the drawing, columns of various types I, 2, 3, 4, 5 and 2 are applied (Fig. 7). The type of the column corresponds to its position in the building:

angular column, lateral, main, etc. The column is made with the input Za (Fig. 4) or the capital Zg, which is a glass for the barrel of the column. The cement mortar of the combined cross (formed by the consoles) is poured through the hole of Sv. The fastening of the metal frame 7 to the brackets is made by means of anchors 36. Square, reinforced concrete plates with protrusions 6a (Fig. 5) are put on crosses and serve as a support for reinforced concrete trays 8 that are laid in all directions and are in turn supporting the base 9 under the lantern 11 with a lid 12. In the non-ceiling part of the ceiling (Fig. 1) a chetyrehskatnaya lid 1.0 is used. Ventilation devices 13 may be provided above the lanterns. Holes 8a are provided for internal drainage in the beams 8.

The construction works are carried out in the following order.

Prior to construction, a project for the organization of work is developed taking into account the availability of mechanisms

and local construction tools. All elements of the coating come from the factory to the construction site accurately labeled. The most bulky parts are transported in a disassembled, compact form. It is advisable to arrange a warehouse of finished structures near the railway with a device between it and a warehouse parallel to the crane. The latter unloads structures arriving by rail on platforms. Moving structures on the installation site is possible in various ways: on the hook of a railway crane; on the platforms moved by the railway crane making loading of the structures; on platforms or sleds with the help of truck or tractors; manually on trolleys.

The sequence of installation works: I) installation and alignment of columns, 2) installation of cantilever crosses, 3) slinging of columns with metal frames, 4) laying of base plates b and along them trays 8, 5) installation on the sides of the trays of covers 10 and four-sided forwards bases 9, 6) installation of lamps 11 (without glazing), 7) installation of covers of lantern 12 or aeration peaks 13, 8) flood of joints of interfaces of individual parts with cement mortar or asphalt tar, 9) glazing of lamps and painting.

The lifting and installation of heavy columns is carried out using a mounting crane. It is possible to install the roof with cranes moving along the mounted part of the ceiling and leading the outboard installation in front. With semi-mechanized installation, it is possible to lift parts from short booms attached to the tops of the columns.

In this case, the method of fastening the arrows must provide a quick rearrangement of their ir; i new position.

The solutions described above and shown in the drawing mainly concern spans with a grid of columns of 6.0 X 6.0 m, 6.0 X 9.0 m, 6.0 X 12.0 m, which is quite common in buildings and light mechanical engineering, textile industry, storage and auxiliary facilities of municipal construction.

When implementing the structure in buildings with large distances between the colonnades, it is advisable to connect adjacent frames 7 with additional beams 1.4 (Fig. 8), on which the tray beams 8 rest.
