Description
Technical field
The present invention relates to a kind of combined wall and construction method thereof, particularly relate to a kind of strong concrete building block being used as to fill with core combined wall outer wall and fill with the filling core combined wall of core and the construction method of this body of wall thereof with this concrete block masonry.
Background technology
China promotes the development of green building and building energy conservation in recent years energetically; to realize in the life cycle management of building; economize on resources to greatest extent; comprise energy-conservation, save land, economize on water, material-saving; protection of the environment and decreasing pollution, for people provide healthy, be suitable for, efficient usage space and the building with natural harmony symbiosis.In order to strengthen carrying out green building, management of building's energy saving, reducing building energy consumption, improving building energy utilization ratio.China is successively proposed relevant laws, the regulation such as " Energy Conservation Law of the People's Republic of China ", " Civil Building Energy Conservation regulations ", " green building assessment standard ", " notice about advancing materials for wall innovation and popularization energy saving building further ".Under above-mentioned policy is guided, new requirements at the higher level are proposed to architectural exterior-protecting construction, material.Body of wall is the main body of building inside and outside space enclosing structure, is one of approach of room thermal insulation.Therefore; development green wall materials has become the basic orientation of China's materials for wall industry development; so-called green wall material adopts clearer production technology; use natural resources less; reduce energy consumption, not only save its energy consumption, the Energy in use of building can also be saved; and a large amount of nonhazardous, pollution-free, "dead" using industry or municipal solid waste to produce, is conducive to the constructional materials of environmental protection and health.
At present, the thermal inertia improving body of wall is one of measure realizing building energy conservation, employing heat preservation composite wall body technique is a kind of technological means of the thermal inertia improving body of wall, namely adopt brick, building block etc. as load bearing wall, self-supporting wall, and with thermal insulation material compound, paste outward with thermal insulation material in early days, afterwards for overcome that outer subsides thermal insulation material heat-preserving wall exists rise drum, crack, aging, come off, the defect such as inflammable, service life is short, there is the improvement opportunity of being built by laying bricks or stones by thermal insulation material in body of wall inside.Thermal insulation material adopts polystyrene foam plate usually.But, the complicated operational sequence that this technology is brought because of compound not only extends construction period, and be difficult to ensure construction quality, and polystyrene foam plate is inflammable, can toxic gas be produced after burning, bring great hidden danger to safe construction, in recent years, just more than once because of the site operation polystyrene foam plate that ignites accidentally on the building site of China, cause very serious safety in production major accident occurs.
The heat-insulation and heat-preservation combined wall of being built by laying bricks or stones by building block/formwork is then the novel energy-conserving wall technology occurred in recent years, Chinese patent 201320825941.X disclosed " a kind of building composite wall building block and body of wall thereof " is the combined wall technology of a kind of heat-insulation and heat-preservation and sound insulation waterproof, its walling unit comprises the sandwich layer in the composite bed and composite bed be made up of foaming thermal-insulating, and the topping be made up of fire proofing material of composite bed arranged outside and solar energy flaggy, wherein, sandwich layer adopts cellular hollow cavity to add stem stem, outer two external surfaces in one direction of building block arrange splicing fit structure, be easy to construction, its weak point is that the exterior material intensity of building block, hardness are more weak, outside is needed to add guard member, as protective screening, fireproof performance has limitation, in anti-outside anti-etc., therefore still there is that problem affecting the durability of the heat preservation and insulation of body of wall and the application life of body of wall of aforementioned conventional composite insulation wall.
Chinese patent 201210209403.8 " Cement polyphenyl granule concrete lattice combined wall formwork and manufacture method thereof and lattice combined wall and manufacture method " thereof then disclose another kind of combined wall improvement opportunity---heat-insulation and heat-preservation fills with core combined wall, it makes half combined wall formwork by light weight concrete construction, two combined wall formworks are fastened docking and forms the wall enclosure with center cavity by sealing compound bondings such as polyurethane, its inside has inner chamber through in length and breadth, then reinforcing bar is set in heart cavity wherein and pours into a mould self-compacting concrete and form reinforced concrete post, be used as the load-bearing main body of combined wall.Be characterized in that the major ingredient granular polystyrene of body of wall formwork is bondd mutually by cement paste shell, form space between particle thus play the effect of insulation, ventilative and waterproof; And granular polystyrene can adopt waste material, realizes twice laid, its weak point is, playing the body of wall formwork of thermal insulation function is split split structure, and it is easily aging and affect body of wall bulk strength that the sealing compound of bonding compares building life; And containing a large amount of granular polystyrenes in this light weight concrete construction, therefore the polyphenyl materials that fire-resistant rank is very high must be adopted, though its fireproof performance is higher than polystyrene foam plate, but fire rating does not still reach A level, still can not avoid at high temperature during breaking out of fire, the explosion of described formwork is ignited granular polystyrene, causes the release of toxic gas, therefore still there is potential safety hazard; Add the hardness of this body of wall formwork and the low of the more non-light weight concrete construction of intensity, similar with last building block combined wall, also belong to the structure of pork pies iron, therefore can be affected the application life of the durability of the heat preservation and insulation of body of wall and body of wall.
