Creixent interès pel sector de la construcció amb fusta al Barcelona Building Construmat 2017

La fusta, com a material de construcció sostenible, avantatjós tecnològicament i estèticament atractiu, captiva als professionals del sector. La fira Barcelona Building Construmat s'ha renovat enguany apostant per la innovació al sector de la construcció i amb remarcable presència de la indústria de la construcció amb fusta. L’Associació catalana de la fusta estructural (Afe) ha estat present a la fira amb un estand on 11 empreses del sector han expo

Timber structure repair of an emblematic catalan industrial building with wood grafts and epoxy resins

Introduction Wood is a living material that must be in optimum environmental conditions or at least it should have a preventive treatment according to the place of exposure, to avoid damage caused by biological or abiological pathologies, which can affect the structural safety of the building. In most cases the middle of the beam is still in excellent condition and can carry the load as before. However, the ends are loaded by shearing forces and a real da

Arquitectura en fusta del romànic català

Arquitectura en fusta del romànic català
Arquitectura romànica L'arquitectura romànica es va desenvolupar per la major part d'Europa Occidental des del segle XI fins ben entrat el XIII. En aquest període l'objectiu era construir temples perdurables i amb la major grandària possible, en busca de l'alçada i la llum. El material fonamental per aconseguir aquestes condicions era la pedra, encara que no es va renunciar a utilitzar altres materials, com la fusta. La fusta es va utilitzar sobretot en

Computer-simulation study on fire behaviour in the ventilated cavity of ventilated façade systems

Computer-simulation study on fire behaviour in the ventilated cavity of ventilated façade systems
ABSTRACT Fire spreading through the façades is widely recognized as one of the fastest pathways of fire spreading in the buildings. Fire may spread through the façade in different ways depending on the type of façade system and on the elements and materials from which it is constructed. Nowadays the trend in architecture is towards a growing usage of lightweight construction systems that are quick to install, versatile and have a high technical and aesthet

Rehabilitació energètica de façanes amb panells de fusta

Els habitatges a Espanya construïts amb anterioritat a l'entrada en vigor l'any 1979, de la Normativa Bàsica de l'Edificació sobre condicions tèrmiques (NBE-CT-79), no complien amb cap normativa d’eficiència energètica i en la actualitat presenten serioses deficiències en matèria d'aïllament tèrmic. Aquest problema és més gran encara en els edificis construïts entre el 1940 i el 1979, amb murs exteriors amb poca inèrcia tèrmica. A la figura 1 es pot obser...

Types of traditional wooden facade in mediterranean climate

In this particular kind of composed architecture, half-timbered walls can be mainly found, although presenting different images, playing with the volume and the walls (outgoing, incoming, design of windows, decorative overhangs, open or closed volumes, etc.) This framework allows you to compose three-dimensional rigid set that integrates walls and floors, sometimes even the armor covers. The structural bays work well, since many of their horizontal pieces ...

Computer-simulation research on building-facade geometry for fire spread control in buildings with wood claddings

Wood is a unique material with respect to fire. Despite being combustible, it is a stable structural element when confronted with flame due to its low thermal conductivity and characteristics of its chemical degradation (Pyrolysis). The level of fire resistance is determined by the mass, size, and configuration of the constructive elements used.   When wood is used as a cladding material, takes the form of boards, plates, or other thin strips, the...

Typological and structural system in traditional timber roof of multi-aisle buildings in Europe

The use of wood in construction of buildings with different uses was common in areas of forests exist in Europe until 19th century. The timber construction followed guidelines based geometric anthropomorphic measures. The structures follow a system of proportions, as a method for modulating the ships, the cross sections and the height of the frames. Timber frame also meet rules for the formation of the slope, usually defined by dividing the cross section o

Uso de la madera en fachadas tradicionales en clima mediterráneo

Asociamos el clima mediterráneo a los países situados en el entorno del mar Mediterráneo y a las zonas de California, suroeste de Australia, Sudáfrica (Cape Town) y del centro de Chile. Las temperaturas son suaves en invierno y cálidas en verano. La media anual va entre los 14º C y 16ºC. El invierno es fresco y el verano templado. La arquitectura tradicional en laz zonas de clima mediterráneo está basada principalmente en la piedra, el adobe y el ladrillo...

Multi-storey timber buildings in Spain: regulation and future projects

Timber structure has been present in hundred of historic building in urban centers in Spain. It was common to use timber structural floors, timber framework with clay or other filler, and structural roofs. But, in the last century the use of structural timber was declining, for different reason, e.g.: the lack of regular supply of wood specially the last 50 years; fast development of other materials like steel or reinforced concrete; shortage an official b...
