PalomuuriParty wall
Esillä olevan keksinnön kohteena on palomuuri, johon kuuluu teräsrakenteinen kehämäinen runko-osa, joka on liitettävissä rakennuksen kantaviin ra-5 kenteisiin, joka runko-osa muodostuu vaakasuuntaisesta ala- ja yläprofiilista sekä niitä yhdistävistä pysty prof i i lei sta, jotka pystyprofiilit avautuvat runko-osan keskiosaa kohti.The present invention relates to a firewall comprising a steel structural perimeter frame which is connectable to load-bearing structures of a building, which frame consists of a horizontal lower and upper profile and vertical vertical profiles connecting them, which open up to the main body. towards the center.
Palomuurin tehtävänä on estää palon leviämistä sen toiselle puolelle ja estää 10 siihen liittyvän rakennuksen tai sen osan sortumisen ja sortumisesta aiheutuvat iskut. Palomuurirakenteelle on annettu tietyt viralliset vaatimukset niiden palonkestävyyden suhteen, esim. Suomen rakentamismääräyskokoelman El mukaiset. Näiden määräysten täyttämiseksi palomuurirakenteiden on läpäistävä tietyt testit. Eräs tällainen testi on standardin EN 1363-2:1999 mukainen 15 testi.The function of a firewall is to prevent the fire from spreading to the other side and to prevent the collapse of 10 adjacent buildings or parts thereof and the impact of collapse. The firewall structure has certain official requirements regarding its fire resistance, eg in accordance with the Finnish Building Code E1. In order to meet these requirements, firewall structures must pass certain tests. One such test is the 15 test according to EN 1363-2: 1999.
Nykyisin palomuurit rakennetaan usein betonista, joka edellyttää vahvoja perustuksia, eikä mahdollista palomuurien siirtämistä, esim. rakennuksen käyttötarkoituksen muuttuessa tai rakennusta laajennettaessa.Nowadays, firewalls are often built of concrete, which requires strong foundations, and cannot be relocated, for example, when the purpose of the building changes or when the building is expanded.
2020
Esillä olevan keksinnön päämääränä on aikaansaada suhteellisen kevytrakenteinen palomuuriratkaisu, joka täyttää viranomaismääräykset, edullisesti vähintään Suomen rakentamismääräyskokoelman luokkavaatimuksen E1-M60.It is an object of the present invention to provide a relatively lightweight firewall solution that meets regulatory requirements, preferably at least class E1-M60 of the Finnish Building Regulations.

metallilevyt. Poimulevy heijastaa palon puoleisella sivulla lämpösäteilyä, jolloin sen toisella puolella on pienempi lämpötila. Poimulevy sallii lisäksi palon 2 johdosta muodostuvat lämpöliikkeet hajottamatta rakenteita. Poimulevy ottaa vastaan iskukuormia, jolloin pystyprofiilit joustavat ja vaimentavat osaltaan iskuvaikutusta.metal sheets. The corrugated plate reflects the heat radiation on the fire side, with a lower temperature on the other side. In addition, the corrugated plate allows thermal movements due to the fire 2 without breaking the structures. The corrugated plate receives impact loads, whereby the vertical profiles are flexible and contribute to the shock effect.
5 Keksinnön mukaisella palomuurirakenteella on päästy palotestissä 90 minuutin kestoaikaan käytettäessä elementeissä 100 mm mineraalivillakerrosta. Siirryttäessä paksumpaan mineraalivillakerrosvahvuuteen on korkeampi kestoaika helposti saavutettavissa.The firewall structure according to the invention has achieved a fire test time of 90 minutes using a 100 mm layer of mineral wool in the elements. When switching to a thicker layer of mineral wool, higher durability is easily achieved.
