Description

Technical field

The technical solution relates to the field of construction, specifically to the insulation of thermal bridges in external fixed boards such as balconies, awnings and canopies.

Background Art

Thermal bridges occur in all commonly used building structures, which separate the environment with different temperatures. These are serious defects in building structures that need to be eliminated as much as possible. These are structures where, due to improper design or the use of unsuitable material, a significantly greater thermal energy transmission is allowed than in the surrounding structures. This fact causes heat loss as well as deterioration of the utility properties of the inner space.

One of the most frequent thermal bridges is the contact of the horizontal structure (ceiling, balcony console) with the vertical (wall) structure. Professional building systems already have this issue partially solved, for example by inserting thermal insulation to the wall rim or by using the so-called ISO nos15. In other cases, the element that is exposed to the outside cold is completely wrapped in thermal insulation or the thermal bridge is interrupted by a complex insulating beam whose structure usually includes separate tensile elements, pressure supports and shear elements. The use of separate elements for the transfer of shear by the rod and pressure by the pressure arm is more progressive, but even in this case the condition is not ideal.

The essence of the technical solution

The above-mentioned drawbacks are largely eliminated by the insulating bearing for external fixed boards according to the invention. This bearing is made of a compact, small-width construction, containing both tensile bars and a pushed abutment for shear forces.

Specifically, the bearing is formed by two "L" -shaped pressure supports and a stainless-steel load-bearing plate 25 that serves as the sole element for shear and pressure transfer, and which is welded to the frame, which is bent to the "L" at its top . From the top, a tensile reinforcement is welded to the frame to which the anchor rods are welded, which are used to tie the bearing into the concrete during assembly on the construction site or in the outdoor plate production plant. The bearing also includes thermal insulation.

Due to its low width and high load-bearing capacity, this bearing can be folded side by side to maximize the load-bearing capacity of the assembled workpiece. Description of the drawing

The figure shows a section of the bearing and a part of the building structure.

Exemplary embodiments

Example 1

The insulating bearing for an external fixed plate, which is a 1.5 m balcony, consists of two pressure supports and dimensions (height χ width χ length) 50 χ 30 χ 60 mm in the shape of the letter "L", ie bent at right angles and supporting stainless steel sheet 2 whose lower part is also bent to a right angle. The two pressure supports I are welded together with the stainless steel sheet 2 which serves to transfer the pressure and shear forces to the frame 6 consisting of two 3 mm sheets bent in the upper part at right angles as well as the pressure supports 1. a tensile reinforcement 4 made of stainless steel logs with a diameter of 12 mm is welded from above, two anchoring rods 3 with a diameter of 8 mm and a length of 500 mm are welded on both sides, which are not parallel. into concrete during assembly. The bearing also includes thermal insulation 5 in the form of extruded polystyrene with dimensions (thickness χ height x width) of 60 x 200 x 200 mm. With this thermal insulation 5, a supporting stainless steel sheet 2 is passed through which the lower part bent at right angles is cut into this thermal insulation 5 and the tensile reinforcement 4 also passes through this thermal insulation 5.

The 1.5-meter balcony contains a total of 3 bearings. The bearing is mounted on the building by placing the bearing on the wall using a pressure support and then pouring it into the ceiling and into the balcony, which is supported during installation. Additional supporting elements of the balcony are then attached to the anchor rods 3.

Example 2 io Bearing as in Example 1, except that the installation of the external fixed bearing in the balcony is carried out directly in the balcony factory (Prefe) and the balcony is already supplied to the building with this bearing, whose protruding part is then embedded in the ceiling structure of the concrete .

Industrial usability

The technical solution is usable in the building industry, especially in the outdoor fixed boards where the thermal bridge has to be separated.
