Description

The building envelope containing building components with fastening elements to the supporting structure on the building

Field of technology

The invention relates to a building envelope comprising peripheral components with fastening elements to a supporting structure on a building.

Prior art

The existing solution of masonry perimeter cladding, prefabricated from silicate sandwich parts, or of light circumferential parts is characterized by a generally rigid connection of these circumferential structures with the inner supporting structure. Due to the effect of, for example, seismic waves transmitted by the subsoil to the supporting structure, dynamic effects are transmitted to the peripheral shell and individual components by means of these rigid joints. Due to deformations reaching a magnitude of the order of a few millimeters, or Even tens of millimeters, caused by these effects, the peripheral components themselves, their joints and especially the airtightness and watertightness of the joints of the peripheral components are often broken. Violation of watertightness can subsequently cause a higher intensity of corrosive processes that disrupt the construction of components, connection details and, last but not least, worsen the quality of the internal environment. In the case of high intensity of dynamic effects, there is a threat to static safety, stability, or. until the collapse of the building structure. The issue of the response of buildings to the effects of dynamic loads caused by technical, natural, or. induced seismicity and preventive measures against disturbance of structures and their joints, or even the loss of stability of these objects, special attention is paid worldwide. These are not only buildings located in the areas of natural seismicity, but also objects located in the areas of intensive rail and wheel transport, surface, or. subsurface, in areas of heavy industrial activity, mining, quarrying, etc.

The essence of the invention

The aforementioned disadvantages of the prior art perimeter cladding solutions are eliminated by the building perimeter cladding system of the buildings according to the invention. The essence of the proposed technical solution is a system of fastening - interconnection of building envelope composed of individual components and supporting system of the building - consisting of at least one flexible damper to connect the perimeter shell to the supporting system and at least one stabilizing element ensuring mutual position of individual components within the envelope .

Decisive from the point of view of the resistance of building structures with regard to dynamic effects is their ability to absorb a certain amount of deformation energy caused by the effect of extraordinary loads of natural, or. technical seismicity, long-term cyclical and variable effects and the effects of external loads. The decisive role in terms of preventive measures against failure of packaging structures and their mutual connections is played primarily by the connecting links between the packaging structure - individual components - and the supporting structure. By appropriately selected stiffness, it is possible to achieve damping of dynamic effects and a significant reduction of deformation effects of dynamic loads. In the proposed technical solution, the individual parts - the peripheral parts - are attached to the supporting structure by means of elastomeric dampers of suitable dynamic characteristics and by means of joints ensuring the stability of the mutual position of the individual parts. Elastomeric dampers prevent - limit - the transmission of dynamic effects causing horizontal deformations of the support system to the packaging structure. Elastomeric dampers according to the technical solution consist of a damping elastomer layer, an anchoring plate for attachment to the supporting structure and an anchoring plate ensuring the attachment of the part. Controlled dynamic properties

- 1 CZ 308318 B6 elastomeric dampers are achieved with different quality - static and dynamic modulus of elasticity, or the thickness and reinforcement of the elastomer layer. Joints ensuring the stability of the mutual position of individual parts and thus the stability of mutual joints are formed by darkness of high-strength plastics such as polypropylene, additionally screwed into built-in metal or plastic sleeve with internal thread and into effective molding of semi-rigid plastics allowing partial rotation of mandrels inserted into these beds. Their function is to stabilize the mutual position of the peripheral components and to significantly reduce the mutual deformations of the peripheral components, so that the risk of losing the sealing functionality of the mutual connections of the peripheral components is reduced to an acceptable extent. Another important part of the perimeter shell solution and its joints for a progressive support system with resiliently inserted parts and controlled response to dynamic effects are EPDM-based sealing profiles inserted into continuous grooves of suitable dimensions around the circumference of the circumferential member, which ensure flexible response of sealing joints between circumferential components for the expected dynamic effects. As a rule, these are profiles solved on the basis of EPDM compressed after insertion into the grooves by a value which is at least 20% greater than the expected maximum deformation movements in the joint under the action of dynamic effects.

The circumferential shell and its joints represent a progressive support system with resiliently inserted elastomeric parts and a controlled response to dynamic effects. The advantage is the elimination of dynamic effects of eg seismic waves, dynamic effects of transport, industrial activity, etc., which cause mainly cyclic horizontal deformations of the load-bearing system accompanied by failures of the inserted structures, ie the non-load-bearing peripheral shell.
