Description

The utility model relates to the field of construction of houses and structures for civil and industrial purposes. It can be used for supporting and enclosing structures of the house, including walls, partitions, ceilings and rafters.

From the application WO 2012114122 A2, 08/30/2012, a structural panel is known containing in its construction wooden I-beams as racks and insulation filling material.

The disadvantages of the known design are that the I-beams are included in the internal structure of one panel, do not protrude beyond the dimensions of the insulation sheathing and, accordingly, do not form cavities with the outer skin of the building. In this case, the racks are installed in an unventilated groove between the insulation panels, which can lead to rotting of the racks.

From the patent US 5003742 A1, 04/02/1991, a prefabricated structure is known, based on a combination of wooden I-beams as racks, insulation panels and enclosing structures.

The disadvantage of this design is that the I-beams also do not protrude beyond the dimensions of the insulation sheathing and, accordingly, do not form cavities with the outer skin of the building. In this case, a complex manufacturing technology is used, since along the perimeter of the insulation panels from the sides, it is necessary to make profiled cutouts for the I-beam shelves.

The closest analogue to the proposed design is the prefabricated structure known from WO 1993014278 A1, 07/22/1993 in which wooden I-beams are used to connect the insulation panels, the insulation panels being placed between the I-beam shelves, and the ends of the beams protrude above the insulation layer forming an air gap between the insulation surface and outer skin.

However, the known solution uses an unprotected insulation without insulating sheathing, while there is the possibility of the insulation getting wet during installation and operation, and as a result, the loss of its thermophysical properties. In addition, this design is used only for the manufacture of floors and ceilings, not walls.

Thus, the objective of the utility model is to create a universal load-bearing structure that provides the convenience of laying communications, creating a ventilated gap inside and outside the structure and the possibility of using panels with various slab and heat-insulating materials as a building envelope.

The problem is solved by the proposed prefabricated load-bearing structure of the building containing I-beams used as racks, logs or rafters, and structurally-insulating panels as insulating and enclosing material between I-beams. Moreover, structurally insulating panels are installed directly between the upper and lower flanges of the I-beams and are attached to the flanges of the I-beams using pins. The joint between the I-beam and the structurally-insulating panel is additionally insulated with mounting foam or other waterproofing materials. In this case, the structural insulating panel is a three-layer composite material consisting of two external insulating layers and an internal porous layer of insulation.

The technical result achieved by the entire set of features proposed by the prefabricated load-bearing structure of the building is to increase the convenience of construction, as well as the durability and versatility of the structure.

A brief description of the drawings.

FIG. 1 - connection of wall racks of I-beam wooden beams and SIP panels as a building envelope.

FIG. 2 - node connection guide from a wooden I-beam with a wall structure.

FIG. 3 - corner connection. Solutions for inside and outside corners.

FIG. 4 - Solution of window and door openings.

FIG. 5 - connection of I-beam wooden beams as a log of overlapping and rafters with SIP panels as a building envelope.

The prefabricated supporting structure of the building consists of wooden I-beams as racks, logs and rafters in the construction of the house, and structural-insulating panels (SIP) as insulating and enclosing material between the racks, logs, rafters. Structurally insulating panels can have a different structure and composition.

Structurally-insulating panels are installed directly between the upper and lower flanges of I-beams used as struts, lag floors or rafter systems. Structurally-insulating panels are attached to the shelves of the I-beam using pins (screws, screws or nails) (Fig. 1.). In the construction of the walls, the upper and lower guides from I-beams are used, on the one hand filled with heat-insulating material (for example, polystyrene foam). Between the shelves of the I-beams of the upper and lower guides, a structural-insulating panel is installed (Fig. 2.).

The joint between the I-beam and the structurally-insulating panel is additionally insulated with mounting foam or other waterproofing materials.

Wooden I-beams can be with shelves from timber, dry planed (width from 30 to 100 mm, thickness from 30 to 70 mm) or with shelves from LVL timber - glued veneer (width from 30 to 100 mm, thickness from 30 to 70 mm ) The I-beam rack can be made of OSB-3, plywood, MDF boards from 6 to 15 mm thick.

Structurally insulating panels are a three-layer composite material. The first and third outer layers are plate material, for example, OSB (oriented particle board), plywood, LSU (glass-magnesite sheet), DSP (cement particle board), fiberboard (wood fiber board). The second (middle) layer is an effective insulation: polystyrene foam, basalt insulation, extruded polyurethane foam. Bonding of 3 layers between each other is carried out at the plants with special polyurethane foam adhesive.

The proposed prefabricated supporting structure of the building can be used for walling. Moreover, it consists of wall racks in the form of I-beam wooden beams (1) connected to structurally insulating panels (2) as a building envelope (Fig. 1). Wooden beams (1) are connected to structurally insulating panels (2) using nails (3), where self-tapping screws, screws or nails can be used as nails.

Structurally insulating panel (2) is a three-layer composite material consisting of two external insulating layers (4 and 6) and an inner porous layer (5) of insulation.

An I-beam wooden beam (1) is a prefabricated structure consisting of an upper and lower shelf (7) and a rack (8) of an I-beam.

Presented in FIG. 1 racks (1) with structurally insulating panels (2) are installed between the lower guide (9) and the upper guide also made in the form of I-beam wooden beams (Fig. 2). Moreover, the guiding I-beams on one side between the flanges of the I-beam are filled with an insert of effective insulation. So in FIG. 2 shows the lower guide (9) an I-beam on one side filled with an insert (10) from a heater.

As insulation for the inserts, for example, polystyrene foam, basalt insulation, extruded polyurethane foam can be used.

The lower guide (9) is mounted on the base (11). The whole structure is fastened with screw connections (3).

The angular connection of the proposed prefabricated load-bearing structures of the building can be performed as follows (Fig. 3).

Two structurally-insulating panels (2) fixed between the posts, which are wooden I-beams (1), are connected at right angles with the help of an additional section of the structurally-insulating panels (14) with an additional pillar (15) of a wooden I-beam, which lasts one from the connected panels and closes the end face of another panel. The whole structure is fastened with screw connections (3).

Window and doorways in the proposed prefabricated load-bearing structures of the building can be performed as follows (Fig. 4).

The aperture on both sides is limited by uprights of wooden I-beams (1). Also, wooden I-beams (1) are installed on top and, if necessary, below the opening.

At the same time, wooden I-beams (1) restricting the opening on one side are filled with an insert (13) made of OSB (oriented chipboard), plywood or wooden blocks, for attaching window or door blocks.

The whole structure is fastened with screw connections (3).

In addition, the proposed prefabricated load-bearing construction of the building can be used as a log of ceilings and rafters (Fig. 5).

In this case, the proposed design is similar to that shown in FIG. 1 and consists of I-beam wooden beams (1) connected to structurally insulating panels (2) as a building envelope (Fig. 5). Wooden beams (1) are connected to structurally insulating panels (2) by means of screw connections (3).
