Abstract

FIELD: construction.

SUBSTANCE: invention is intended for construction of pre-fabricated buildings. In the prefabricated buildings manufacturing method, including the column-beam wooden frame filling with wall and roof sandwich panels, double-glazed windows without frames, wooden frame of the building is made of glued elements, sawn in joints. Obtained structure is filled or covered with steel colored sandwich panels based on polyisocyanurate (PIR), large-size double-glazed windows and doors. From the outside, the mounting gap after insulation with mounting foam is closed with aluminum L-shaped corners on hidden self-tapping screws, on the outer side in the lower horizontal plane an aluminum Z-shaped profile is used as a dropper. Sandwich panel is fixed from inner side to steel angles, doors and double-glazed windows are fixed to L-shaped aluminum angles from outer and inner sides.

EFFECT: improved thermal insulation of the structure.

Description

The invention relates to construction and is intended for the construction of industrial and civil buildings and can be used for the rapid construction of facades of buildings and structures.

The method for manufacturing prefabricated buildings is known from the description of the patent for the invention of a building module for the construction of buildings (see RU 2631125, publ. 09/19/2017) (1). The construction of a building from standardized building modules is carried out using modules of the same size, consisting of rigidly welded metal structures. Structural columns or building modules are stacked on top of each other, connected using high-strength bolts through bolt holes in the slats of the supporting columns. One column is used to support two adjacent building floors and ceilings. The construction module for the construction of buildings is assembled as follows. Construction modules are delivered to the site in disassembled form: floor and ceiling, load-bearing walls, which are supplied with utility networks and factory finishing, load-bearing columns, single-level or two-level, depending on the architectural and planning solution, enclosing panels and double-glazed windows. Thus, when disassembled, it is possible to transport two such sets of building modules on one trailer per trip, which simplifies and reduces transportation costs. The building is erected using a traverse or slings. The main lifting device is a tower or wheeled crane.

This analogue is not universal, since non-standard sandwich panels are used.

The closest analogue, in the opinion of the applicant, is the façade of a building (see RU 130330, published on October 29, 2012), containing guide posts installed on the interfloor ceilings and connected by means of retaining inserts with horizontal elements, while the horizontal elements of the facade are made from pre-assembled window blocks with the possibility of installing double-glazed windows in them, and filling elements are installed in the spaces between adjacent window blocks with double-glazed windows.

The proposed analogue (2) has metal inclusions, which are “cold bridges” in contrast to the proposed all-wood structure.

The technical result of the claimed invention is to increase the thermal insulation of the structure, as well as to ensure versatility of use.

The technical result is achieved by creating a method for manufacturing prefabricated buildings, including filling the walls of buildings made of a post-transom wooden frame with wall and roof sandwich panels, double-glazed windows without frames.

The method is characterized by the fact that the building frame is designed according to the principle of a mullion-transom structure from wooden laminated beams, CNC-cut at the joints, the resulting structure is filled or covered with painted steel sandwich panels based on polyisocyanurate foam (PIR), large-format double-glazed windows, frame windows and doors, on the outside, the installation gap after insulation with polyurethane foam is closed with aluminum L-shaped corners using hidden screws; on the outside, in the lower horizontal plane, an aluminum z-shaped profile is used as a drip line.

In a preferred embodiment, the panel is fixed from the inside to steel corners.

In the preferred embodiment, windows, doors and double-glazed windows are mounted on L-shaped aluminum corners on the outer and inner sides.

In the preferred embodiment, the roof is made of roofing sandwich panels, taking into account the pitch of the longitudinal beams according to the load-bearing capacity of the panel

The essence of the invention is illustrated by drawings, in which:

Fig. 1 - image of installation of a double-glazed window from the inside;

Fig. 2 - image of the window fastening from the outside;

Fig. 3 - image of fastening a wall sandwich panel;

Fig. 4 is an image of an application example.

The method of manufacturing prefabricated buildings consists of filling the walls of buildings made of a post-transom wooden frame with wall and roof sandwich panels and double-glazed windows without frames.

The invention discloses a method for using and securing wall and roof sandwich panels and double-glazed windows without frames in the private and commercial construction of buildings and structures made of a post-transom wooden frame.

In the claimed method for manufacturing prefabricated buildings, the building frame is designed according to the principle of a post-transom structure from wooden laminated beams, CNC-cut at the connection points. The resulting structure is filled or covered with painted steel sandwich panels based on polyisocyanurate (PIR) foam, large-format double-glazed windows, framed windows and doors. The panel is fixed from the inside to steel corners. On the outside, the installation gap after insulation with polyurethane foam is closed with painted aluminum L-shaped corners using hidden screws. Windows, doors and double-glazed windows are mounted on similar L-shaped aluminum corners on the outside and inside. On the outside, in the lower horizontal plane, an aluminum z-shaped profile is used as a drip edge. The roof is made of roofing sandwich panels, taking into account the pitch of the longitudinal beams according to the load-bearing capacity of the panel.

The use of wall and roof sandwich panels, double-glazed windows without frames in a frame made of laminated beams allows the construction of warm buildings and structures in the shortest possible time with a ready-made finishing coating. The use of double-glazed windows without frames significantly reduces the cost of glazing openings by eliminating the manufacture of the frame itself. The role of the frame is performed by the post-transom frame of the building. The thickness of the wooden beams is sufficient to prevent dew point from entering the room. This method significantly reduces the cost and time of construction of private and commercial buildings and structures.

In practice, sandwich panels are currently used mainly for the construction of buildings and structures using metal frames. This solution has proven itself, but the timing of the building’s construction, cost and aesthetic appearance do not allow the use of standard methods for all the needs of private and commercial housing construction.

The method of manufacturing prefabricated buildings can be used in private and commercial construction of knowledge and structures.
