The new national standard "Building Design fire code" (GB50016-2014) issued, since May 1, 2015 implementation. The new "building design fire protection code" (GB50016-2014) and "building design fire protection code" GB50016-2006 and "high-rise civil building design fire protection code" GB 50045-95 (2005 edition) compared, what are the changes?

EPS composite insulation technology is an efficient and economic, widely used exterior wall insulation technology, it is composed of load-bearing or enclosure wall, EPS composite insulation layer, alkali resistant glass fiber mesh anti crack mortar protective layer, elastic putty, exterior wall coating or tile surface layer.

Before the insulation board fire caused attention, the most troublesome problem of the external insulation system is actually "falling off", according to the existing experience and lessons, outsideHeat preservation materialMost of the fire accidents occur in the building under construction, this time people have not moved in, what accident problems can also be rectified in time, of course, the construction period and cost must increase. However, for the already built buildings, when people generally move in, if some accidents happen to the external insulation system and need to be repaired, it will be a big problem. As shown in the following video, a large area of the external insulation and decorative layer of this building fell off, almost injuring pedestrians and causing a lot of panic.

###Fiberglass mesh for reinforcement - Part 2: Industry standard for building materials of fiberglass mesh for external insulation of polymer based exterior walls (JC) JC561.2-2006 This part specifies the terms and definitions, classifications and codes, requirements, test methods, inspection rules, marking, packaging, transportation and storage of glass fiber mesh cloth for external insulation of polymer-based exterior walls (hereinafter referred to as wall mesh cloth). This part is suitable for non-alkali, medium alkali glass fiber net cloth coated with organic materials, mainly used as polymer based exterior insulation finishing system reinforcement material, can also be used as gypsum, plaster, asphalt, resin and other matrix reinforcement material.

Recently, the Ministry of Housing and Urban-Rural Development approved 24 standard designs compiled by 24 units, including China Building Standards Design and Research Institute Co., LTD., as national building standard designs. The 24 standard designs will come into effect on August 1, 2015. Among them include "brick wall building, structural structure" (15J101 15G612), instead of the original "brick wall building structure" (04J101), "brick wall structure" (04G612).

Inspection rules, product certificates and instructions, packaging, transportation and storage. This standard applies to the materials for external thermal insulation system of moulded polystyrene board and thin plastered exterior wall used in civil buildings.

Recently, editor in chief by Beijing construction building technology company, Beijing housing and urban and rural construction committee, the Beijing municipal bureau of quality and technical supervision jointly issued the Beijing local standards "hard foam polyurethane composite board now wipe light mortar exterior insulation engineering construction technical regulation," insulation board exterior insulation foam cement engineering construction technical regulation, It will be implemented on July 1, 2014.

1. Permeable pavement Permeable brick paving, permeable cement concrete paving and permeable asphalt concrete paving, cobblestone and gravel paving in inlaid grass brick and garden paving also belong to permeable paving.

This part specifies the terms and definitions, classifications and codes, requirements, test methods, inspection rules, marking, packaging, transportation and storage of glass fiber mesh cloth for external insulation of polymer-based exterior walls (hereinafter referred to as wall mesh cloth).

This standard specifies a method for measuring tensile breaking strength and breaking elongation of glass fiber woven fabrics. This standard applies to unimpregnated fabrics and fabrics impregnated with wetting agents or hardened materials, but does not apply to fabrics coated with rubber or plastic.

Beijing Municipal Commission of Housing and Urban and Rural Development and Beijing Municipal Bureau of Quality and Technical Supervision approved Beijing "Indoor Temperature Energy Saving Monitoring Standard for Air Conditioning heating in Public Buildings" (DB11/T1005-2013), which was officially implemented on October 1, 2013.

Recently, Guangdong province officially approved the release of the "water-based polyurethane anticorrosive coating (two-component) standard", the standard will be implemented from March 31, this is China's first water-based anticorrosive coating standard. The promulgation and implementation of the new standards, to promote the province's product standard system construction, waterborne coatings industry is helpful to guide the industry development, waterborne anticorrosion coating will drive heavy anti-corrosion materials production enterprise to develop towards the direction of green environmental protection, improve the coating process automation level, enhance the independent innovation ability of enterprises, promote the ship coatings and other products to reach the level of similar foreign products as soon as possible.

National Standardization Administration recently released 2012 No. 42 announcement, approved the release of recommended national standard GB/T 29416-2012 "building exterior insulation system fire performance test method". The standard is the first to be published and will come into effect on October 1, 2013.

Standard introduction: JC/T841-2007 Alkali resistant glass fiber mesh building materials industry standard (JC) JC/T841-2007 this standard is applicable to the use of alkali resistant glass fiber yarn woven, and coated with organic materials treated mesh; The product is mainly used for cement-based products of reinforcement materials, such as partition board, grid board, external wall insulation engineering materials, etc., can also be used as polymer and gypsum, asphalt matrix reinforcement materials.

Beijing Building Materials Quality Supervision and inspection Station and Beijing Urban Construction Technology Promotion Association and other units, the "external wall insulation construction technical regulations (external wall insulation decorative board practice)" has been jointly approved by Beijing Housing and Urban and Rural Development Committee and Beijing Bureau of Quality and Technical Supervision for Beijing local standard, no. DB11/T697-2009. The standard has been implemented since April 1, 2010, and will replace the original Beijing engineering construction local standard DBJ/T01-92-2004 "External wall insulation construction technical specification (polymer cement polystyrene insulation board practice)"

Ministry of Construction on the release of industrial product standard "concrete expansion, expansion type building anchor bolt" announcement Announcement No.227 of the Ministry of Construction of the People's Republic of China

According to comrade event indicating light spirit, calibration, slurry sampling, department, real estate and housing industry center in office and with the cooperation of iron macro comrade, involves the development of energy conservation of the ministry ground-saving residential and public buildings and promote "four" relevant laws and regulations, standards and policies and measures system has carried on the preliminary examination. Summary is as follows:
