Description
Technical field
The present invention relates to a kind of steel constructions and insulation construction integral type solid model shear wall and construction method, belong to Building technology
Field.
Background technique
The either light steel of the steel house in China or general steel system are substantially all the skill for being derived from and introducing developed country
Art, the original technology of non-native.Steel building has the spies such as antidetonation, hurricane resistant, efficiency of construction height and discarded recovery utilization rate height
Point has become the main future developing trend in world architecture field.Steel construction is divided into lightweight steel construction and general steel structure, light steel knot
Structure mainly builds low-rise dwelling, mostly cold bending thin wall, and light steel construction mode is stressed-skin construction, is lightgage steel joist and thermal insulation material wood
The multilayer composite of matter structural slab (OSB).Although faster than traditional brick mix structure speed, now with the increasing year by year of labour cost
Long, this method of construction by live man-made assembly increasingly shows the deficiency of building low efficiency, wooden due to using
Structural slab and foamed material, there is the hidden danger of fire and the original deficiencies such as waterproof, termite-proof.
General steel structure can build multilayer and skyscraper, since the volume that general steel structure is mainly H profile steel component is larger,
The building enclosure construction style of filling wall is mostly used, H profile steel and filling wall fusion structure connectivity are poor, and general H profile steel is exposed solely
It stands in the inside of wall, such steel construction is easy to corrode in air, varies with temperature fluctuation and generates and expand with heat and contract with cold, occurs linear
It splashes swollen, brings to building enclosure stress rupture, lead to building enclosure local cracks, heat preservation and waterproof performance are destroyed, simultaneously
The frightful sound that steel structure breathing generates often is heard, since exposed steel part brings certain difficulty to interior decoration and occupies
Certain space, this filling wall such as aerated blocks building construction efficiency is lower, and exterior wall heat-preserving system and structure cannot
Integral type, is easy crack, and heat-insulation system fails because of infiltration.
Summary of the invention
According to the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is providing a kind of steel construction and protecting
Warm structural integrity formula solid model shear wall, is the super low energy consumption construction for being suitable for low layer, multilayer, high level extensively, and antidetonation resists
Hurricane performance obtains more significantly improving, efficient building construction, energy-efficient, section material, saving of labor, structure and heat-insulating integral formula same longevity
Life, fire prevention, waterproof, termite-proof, sound insulation is comfortable, environmentally friendly, and transportation radius (than PC assembled) improves ten several times, extensive suitable
Plateau, puna environment and maritime with high salt, high humidity and hinterland are answered, is the wind vane of future architecture technology.
Steel construction of the present invention and insulation construction integral type solid model shear wall, including steel construction, two inside and outside steel construction
Side is respectively equipped with interior solid model plate and outer solid model plate, is filled with foaming in the space that steel construction, interior solid model plate, outer solid model plate are gone along with sb. to guard him
Concrete.
Interior solid model plate, outer solid model plate can be cement fibrolite plate, calcium silicate board, magnesia fibers plate, lithotome plate, stone
Cream plate, exterior wall finish composite plate etc..At least one side roughening of outer solid model plate is handled, strong with the compound removing of foamed cement to improve
Degree.Corresponding plate stitch should be reserved when the two adjacent plates up and down connection of outer solid model plate.Interior solid model plate, outer solid model plate except vertical and
It is laterally fixed outer, interior solid model plate, outer solid model plate inside be preferably provided with intersection construction again, reinforcing rib is equivalent to, with enhancing
It is anti-to pour foamed cement mortar pressure and cause the fixing intensity of template evagination.
Foamed concrete of the invention, can be pure foamed cement or in foamed cement slurry, add aglite or
The mixed slurry of chopped strand such as adds EPS expanded beads, addition expanded perlite, glass microballoon or or chopped natural plants
Fiber or staple fibre etc. increase thermal insulation property or increase strength character to reduce density.Foamed cement filler material mainly plays
Structure and heat insulation integrated effect, can keep the temperature and have good structural strength, with fire-proof and water-proof insect prevention and cheap
The advantages that, dry density is in 200-500kg/m3Between.
Door or window can be arranged in the present invention on shear wall, set between the position of door or window, interior solid model plate, outer solid model plate
Have closing closure plate (as shown in figure 11), closing closure plate material can use OSB plate, and foamed concrete is from door or window when preventing from pouring
Position outflow.
Interior fixed heat insulating strip and outer is respectively equipped with inside and outside the steel construction between interior solid model plate, outer solid model plate
Fixed heat insulating strip.Inside and outside fixed heat insulating strip can be lateral, vertical, diagonal cross, and heat insulating strip can be natural batten, sham wood
Item or plastics, composite slats such as wood moulding, high-density plastic's plate etc..It is main, and there are four effects:
1. especially peripheral template thermal coefficient is higher, if directly joined with steel structure since inside and outside solid model plate density is larger
It connects and has heat bridge cold bridge effect.Fixed heat-insulating bridge-cut-off plays the role of heat-insulating bridge-cut-off using the lesser material of thermal coefficient
2. template and steel structure hardness are big, directly fixed with adjusting screw, it is bad to eat nail property, is not fixed firmly, when by temperature change
Move back nail phenomenon when with vibration, thermal insulation item have good elasticity, toughness and it is good eat nail, can be fixed stably for a long time
It is qualitative.
3. another effect for increasing heat insulating strip is exactly good leakproofness, the sealing function of waterproof spillage is played.
4. wherein the fixation heat insulating strip of diagonal cross is to play most important anti-mould evagination effect of rising of being in the milk, that is, interior
