Description

The technical field to which the invention relates.

The invention relates to the field of low-rise construction, namely, to large-panel low-rise housing construction, and is intended for use in building structures for connecting large-format wall panels (load-bearing), as well as interior partitions made of fiberboard. The connection described in the application prevents the effect of opening the joint and eliminates the possible displacement of the panels relative to each other.

The prior art.

Known butt joints of fiberboard panels having a panel mount, including connecting profiles made of profiled metal. Profiles are installed during the installation of panels or laid in the production process. Fastening and screed of panel elements is carried out with screw ties. The cost of the elements of the connection, the technological complexity of manufacturing and installation lead to an increase in the cost of the finished product.

Various joints are also known using a tenon groove, but they are presented only in the category of joining panel frame elements. The frame is usually made of wood, which reduces the operational and fire-retardant characteristics of the structure.

Of the known closest is the connection used in the wall panels of the Swedish company Traullit, with V-shaped and rectangular grooves, which are filled with reinforced concrete during the installation of panel elements. The panels are completely made of low density fiberboard, but concrete reinforcement works increase the time and cost of the structure.

As a rule, all currently known compounds are based on the use of materials other than the materials from which the panel itself is made.

Disclosure of the invention.

The objective of the present invention is:

- Improving the reliability of the connection;

- saving the panel format;

- the use of homogeneous materials in the elements of the joint;

- preservation of thermal resistance at the joints of panels;

- unification of panels;

- ensuring maximum factory readiness for the installation of fiberboard panels;

- reducing the complexity when installing panels;

- increase the economic effect.

In common tenon-groove joints, the usable area of the panel is reduced by the size of the tenon in the manufacture of the joint. With the proposed connection design, the original panel dimensions are maintained, since the keyway slots are made in the inner layer of the panel.

In the joined ends of the panel, rectangular grooves are made, into which one or more rectangular keys are installed during installation. The keyway is made when forming the panel or is milled after reaching the technological strength of the fiberboard. The key can be installed and pinned in the factory, which will reduce the complexity and reduce the installation time of the elements. In order to increase the reliability of fastening, the keys are installed on a cement or adhesive composition.

The ability to install the keys from one or the other end or from both allows you to unify the panels without dividing them on the mirror panel (with a left or right spike). This is especially important when installing keys in the factory.

Thus, the plate can be produced in several modifications: a spike “left”, a spike “right”, a spike from both ends or without a spike.

The keys with panels are fastened with cylindrical pins. The holes in the panels for the pins are drilled at the factory. The holes are made through or with a depth sufficient to guide the drill during manual drilling of a hole in the key at the construction site. The diameter of the holes and their number is determined by calculations depending on the purpose of the panel.

To achieve a tight connection, taking into account the elasticity of the fiberboard, panels with installed keys are tightly pressed in the joint plane, holes are drilled in the key through the holes in the panels and pins are installed in tight fit. This allows you to keep the voltage tightened in the connection zone between the opposite rows of pins and to ensure non-disclosure of the joint.

The plate and the key are made of one material - fiberboard of different densities, the pins are made of wood. The use of homogeneous materials at the junction does not violate the thermal resistance of the panels.

The invention is illustrated by drawings.

Figure 1, 2, 3, 4 depict options for the connection of fiberboard panels. A fiberboard key 3 is installed in the slots 2 of the panels 1, made at the factory. Holes 4 in the key for the pins 5 are drilled through the holes in the panels. The pins are set in a tight fit.

Figure 1 shows the connection of panels installed in the same plane.

Figure 2 shows the connection of panels installed at right angles.

Figure 3 shows the connection of panels installed at an arbitrary angle (external angle).

Figure 4 shows the connection of panels installed at an arbitrary angle (internal angle).
