RU179966U1 - Ribbed Reinforced Concrete Prefabricated Monolithic Panel with Prefabricated Bearing Frame - Google Patents

Abstract

The utility model is a reinforced concrete precast-monolithic panel for construction. A distinctive feature of this panel is a prefabricated supporting frame made of reinforced concrete elements, which can fulfill both the role of beams and the role of vertical supporting elements. Thus, these panels can be used both for the construction of walls, and for the installation of ceilings and coatings. The use of separate prefabricated elements and the assembly of the panel in the immediate vicinity of the construction site reduces the need for large vehicles (panel carriers), as well as the need for production facilities at the place of direct assembly of panels. Also, for the production of individual elements of panels in the form of beams and racks, significant production areas are not required in view of the absence of the need for equipment of a significant size and a small range of necessary products.

Description

The technical solution relates to the field of industrial and civil construction of heavy concrete structures of prefabricated monolithic structures of buildings and structures for industrial, civil and agricultural construction.

Known ribbed reinforced concrete panel - three-layer with a heater based on polystyrene foam, the outer layers of which are connected by longitudinal and transverse reinforced concrete ribs, made in accordance with GOST 31310-2005 “Three-layer reinforced concrete wall panels with effective insulation. General specifications. " The specified panel is manufactured using heavy stationary equipment in mass production in several stages:

- assembly and installation in the form of a reinforcing cage and the insulation fixed in it;

- pouring concrete mixture with the mold;

- grouting concrete of the upper surface;

- steaming the product in an autoclave, a steaming chamber or storage for hardening concrete in natural conditions.

The disadvantage of this panel is the low manufacturability and the large required floor space for the manufacture of ribbed panels of a similar design since its production requires a steel mold or wooden formwork for the entire size of the product.

In addition, if you need to move this panel from the thermo-molding stand to the place of further strength gain after gaining 70% strength and when tilting it, various kinds of devices are required, including conveyors and heavy tilters, which complicates the production process and makes it impossible to organize it in the vicinity from the construction site.

The technical result, which this technical solution is aimed at, is to eliminate the above disadvantages.

This is achieved by the fact that the ribbed precast-monolithic panel consists of a frame that is assembled from prefabricated reinforced concrete beams by welding embedded parts of the external beams / ribs and welding to the reinforcing outlets and embedded parts of the external beams of the reinforcement of the inner transverse ribs and reinforced concrete thin-walled shelves. Moreover, the internal transverse edges and the reinforced concrete shelf are made together by pouring concrete mixture into the former, the external faces of which are the frame of welded longitudinal and transverse external reinforced concrete edges of the future panel.

This technical solution is characterized in that the external beams / ribs (beams or columns, depending on the purpose of the panel) can be manufactured separately and in another production, including using autoclaves with a narrow diameter, which saves temporary production areas.

It differs in that after setting the concrete there is no need to wait for 70% of the set of strength - you can immediately move the panel with the help of a universal beam, which can be attached to the centers of the transverse external edges. Using the same traverse, it is permissible to tilt the panel 360 degrees.

It is distinguished by the fact that after setting concrete, a further set of its strength can occur in a vertical position, which saves floor space.

The ribbed reinforced concrete precast-monolithic panel with the precast supporting frame is produced in series. External ribs / beams longitudinal 1 and transverse 2 are welded through steel embedded parts 3 (see Fig. 1 and 2). The reinforcement of the thin-walled shelf 4 and internal ribs 5 is installed in the formed frame, then the thin-walled shelf with ribs 6 is poured with concrete with concrete mixture (see Fig. 3). In the form formed by the outer beams 1 and 2 and the thin-walled ribbed shelf 6, the heater 7 is laid (see Fig. 4). After that, a protective layer of cement-sand mortar 8 is applied to the insulation surface (see Fig. 5).
