Description

The technical field to which the utility model relates.

The utility model relates to the field of construction, namely to the construction of frame-panel high-rise buildings.

State of the art

A building is known with a precast reinforced concrete frame, including columns and crossbars supported on the console of columns, and an external wall fence made in the form of masonry placed in the alignment between the external columns of the frame with support on the crossbars, while the masonry and frame elements are sheathed with cladding panels outside (see patent SU 63655, IPC: E04B 2/56, op. 08.31.1944 g).

A building with a multilayer enclosing structure is known, including a supporting element with openings and slopes, made in the form of masonry from structural and heat-insulating cellular concrete, and a finishing element fixed to its front side, containing a system of cells with insulation, a reinforcing mesh with anchors, a covering layer of plaster and textured-finishing layer (see patent RU 2994, IPC: E04B 2/00, op. 16.10.1996).

Recently, hinged ventilated facades are widely used as a finishing element, for example, as in patent RU 34557, IPC: E04F 13/00, publ. December 10, 2003. Such facades have full factory readiness, which simplifies the work carried out at the construction site and excludes “wet” operations.

A significant drawback of all of the above analogues is the use of wall masonry for external fencing, because At present, there is an acute problem of the availability of qualified masons and the high cost of their services.

As the closest analogue, by the presence of essential features similar to those of the claimed technical solution, the technical solution of a multi-storey building is disclosed in patent SU 1805174, IPC: E04B 1/18, publ. 03/30/1993

The closest analogue is characterized by the following features similar to those of the claimed technical solution: the presence of a precast concrete frame, including columns and external and internal crossbars placed between them, the presence of an external fence from non-supporting wall panels, which are placed together with the external crossbars in the alignment between the columns of the outer row and rigidly connected to them.

Placing an external fence in the alignment between the columns allows you to exclude internal corners, thereby expanding the internal volume of the premises, and also provides high rigidity of the building's structural system.

To ensure the required thermotechnical characteristics of the building, the wall panels have a significant thickness corresponding to the width of the column, and the external crossbars (the same as the strapping beams) are provided outside with a vertical curtain wall that protrudes beyond their edges and overlaps the joints of the outer wall panels.

The disadvantages of this solution include the complexity of the production, transportation and installation of wall panels, due to their significant dimensions and weight, as well as the need to form a front facing layer on the panels.

Utility Model Disclosure

The inventive utility model is aimed at simplifying the technology of production, installation and transportation of wall panels while maintaining good thermal characteristics of the building, as well as an additional increase in the usable area of the interior.

The problem is solved due to the fact that in a multi-storey building containing a precast concrete frame, including columns and external and internal crossbars placed between them, and wall panels of the external fence, placed together with external crossbars, in the alignment between the columns of the outer row and rigidly connected to them , according to the claimed utility model, wall panels are made with a thickness corresponding to 0.25-0.3 column widths, and are installed with the placement of its front surface in the same plane with the front faces columns, between which they are located, while the outside wall panels and frame members are lined with insulating plates or ventilated facade.

Unlike the closest analogue, the wall panels of the external fencing of the proposed building have a significantly smaller thickness, and therefore weight, which can greatly facilitate the production, movement and installation of wall panels, and reduce the cost of their production process.

At the same time, reducing the thickness of the panels and their corresponding placement between the columns allows you to increase the usable area of the interior of the building without expanding the building spot.

So in a specific embodiment of the utility model, the thickness of the wall panels is 100-120 mm with a column width of 400 mm. As a result, at least 280 mm is added to the length of the room, which provides a significant increase in the usable area of the premises to 1.5 m ² or more.

At the same time, the implementation of the outer cladding of heat-insulating plates or elements of the ventilated facade, covering all connecting seams and covering not only wall panels, but also frame elements, allows to provide good thermal insulation characteristics of the external fence with a small thickness of wall panels.

The presence of facade elements forming the front surface of the building eliminates the need to form a special outer layer on the wall panels and facilitates the simplification of their manufacturing processes.

Thus, the aforementioned set of essential features of the proposed technical solution ensures the achievement of the following technical results, namely: an increase in usable area and simplification of the production, movement and installation of wall panels, while maintaining the required thermal characteristics of the building.

In almost all typical series, wall panels are run per floor. As a result of the reduction in thickness, it became possible to perform a wall panel of two or more parts that are interconnected already at the production site during installation. The reduction in the dimensions of the prefabricated wall fencing unit made it possible to further facilitate the production and installation of assembly units and reduce the requirements for their transportation. So it became possible to transport wall panels in a horizontal position using conventional transport.

In the case of columns with consoles, the external crossbars are installed on the console of the columns, and on the wall panels corner cuts are made along the upper edge for the possibility of placing the console consoles.

Utility Model Implementation

A multi-storey building with a precast reinforced concrete frame (see Fig. 1, 2) contains columns 1, external crossbars 2 (the same as strapping beams), internal crossbars 3 and wall panels 4, placed together with external crossbars 2, in the section between the columns 1 outer row and rigidly connected to them. The front surfaces of the columns 1 of the outer row, wall panels 4 and outer beams 2 are placed in the same plane with the formation of one flat outer surface.

Wall panels 4 (see Fig. 3) are made with a thickness corresponding to 0.25-0.3 of the width of the column 1. With a column width of 400 mm, the thickness of the wall panels 4 is 100-120 mm.

External crossbars 2 are installed on the console 5 columns (see Fig. 1, 2) or on other supporting elements (see Fig. 4, 5).

In the first case, along the upper edge of the wall panel 4, corner cutouts 6 are made to accommodate the consoles 5 of the columns 1 (see Fig. 3a). The term "cutouts" is adopted conditionally, because the said "cutouts" are formed during the manufacturing process, during the formation of the panels. In FIG. 3b shows a wall panel without "cutouts".

The connection of wall panels with columns 1 is carried out by means of reinforcing outlets and embedded parts 7.

In FIG. 4 and 5 show an example of the execution of wall panels 4 of two parts 4 ′ and 4 ″, rigidly interconnected. In each of the parts, an opening can be made: window or door (see Fig. 6). Outside, wall panels and frame elements are lined with heat-insulating plates 8 or a ventilated facade.

Wall panels 4 are made of ordinary reinforced concrete and do not require finishing of the facade layer.

The implementation of the outer wall fencing with a multilayer provides good thermal performance of the building.
