Description
[technical field]
The present invention relates to one kind to exempt from formwork complex heat-preservation sound insulationg board and heat insulating and sound insulating floor method of construction, is applied to building,
Especially assembled architecture belongs to building materials field.
[background technique]
It is a large amount of to be built using the building of prefabricated concrete structure as country greatly develops assembled architecture.Dress
It is one of the important component of horizontal member in assembled architecture with formula floor.Currently, assembled floor mainly includes assembly
Two kinds of formula concrete folding plate, metal floor support plate forms.
Assembly concrete superimposed sheet be at the top of precast slab at the construction field (site) after pouring concrete and the entirety that is formed
Flexural member.Advantage is template of the precast slab as top placing concrete, saves a large amount of temporary templates, saves
All or part of shuttering supporting.The disadvantage is that being constructed twice by entire plate through-thickness is artificially partitioned, globality is poor, together
When, assembly concrete overlapping plate thickness is typically no less than 120mm, and wherein pre-erection is not preferably less than 60mm, rear pouring concrete
Overlapping layers is not less than 60mm.Much larger than the slab thickness 100mm of traditional architecture, project cost is many higher；Assembly concrete
There are construction joints between superimposed sheet and assembly concrete superimposed sheet, are easy to appear later period shrinkage cracking；Assembly concrete overlapping
The prefabricated portion of plate is difficult to cutting whole into sections again at the construction field (site), and construction flexibility is poor；Plate thickness generally within 150mm, sound insulation,
Thermal insulation property is poor, can not meet green building requirement, needs in addition to increase tolerant noise-insulating warm-keeping measure in plate face or board bottom.
And metal floor support plate is to do liner plate using concave-convex alternate die mould sheet metal and pour with cast-in-place concrete to prop up together
Hold the composition monolithic devices floor on beam.Template due to die mould sheet metal as placing concrete is used as permanent formwork, saves
A large amount of temporary templates, eliminate all or part of shuttering supporting.Disadvantage be die mould sheet metal fire prevention, antirust ability compared with
Difference；The sound insulation of metal floor support plate, thermal insulation property are poor, can not meet green building requirement, need in addition to increase in plate face or board bottom
Add tolerant noise-insulating warm-keeping measure.
The livable building of modern healthy, which has floor sound insulation and heat-insulation and heat-preservation, is strict with:
(1) floor insulates against sound
Floor sound insulation is one of an important factor for residential environment ensures, still, in previous architectural design is paid attention to this insufficient.
The continuous improvement that requires with the people to housing quality and government's correlation living environment method gradually perfect, and house is set
It should pay much attention to floor sound insulation problem in meter.The sound insulation of floor includes the isolation performance to two kinds of sound of strike note and air-borne sound.One
As for, reach floor air-borne sound sound insulation standard be not difficult because currently used Reinforced Concrete Materials have preferably every
Exhausted air acoustic performance.According to surveying and determination, the armored concrete air sound insulation Rating of the single value amount of thick 120mm is in 50dB or so, if added again
Upper others construction measure effect is with regard to more preferable, but the armored concrete of 120mm thickness is then inadequate to isolation strike note.At this stage I
It is supplied in state's real-estate market in the commercial residential buildings that consumer uses, is designed by the first standard of finishes, building therein
Face reinforced concrete structure layer general thickness is between 100~150mm, making cement mortar levelling layer above structure sheaf, floor
Weighted standardization hits sound pressure level substantially in 80dB or so.If resident carries out being laid with wood on mattess when secondary decoration
Floor is greatly improved to floor sound insulation, including solid wooden floor board and compoiste wood floor have good strike note sound insulation effect, real
Measured value is generally less than 70dB, meets the lower bound requirement in Code for design of dwelling houses to floor anticollision sound.But if the surface layer selected
Finishing material is hard material such as granite, floor ceramic tile etc., and sound pressure level is hit in the weighted standardization of floor just can be only sustained at
Code requirement is not achieved in 80dB or so.All kinds of building floors are hit in " Code for sound insulation design of civil buildings " GB50118-2010
Sound sound insulation Rating of the single value amount lower bound is hit to require to be typically less than 75dB.
It is the reinforced concrete floor of hard material for surface layer finishing material, a kind of method more popular at present is " floating
Build floor " method that is, in the general 4~10mm thickness vibration damping ground cushion in one layer of structure floor upper berth, then is pouring 40~80mm coagulation above
Native and built-in reinforcing bar forms " sandwich " elastic interlayer structure.According to Tsinghua University's Architecural Physics laboratory testing conclusion, vibration damping
The floating floor of ground mat hits sound pressure level improvement amount Δ Lw up to 22dB (specific value and ground than the weighted of former concrete floor
The material of pad is related with elasticity), field measurement strike note oise insulation factor Ln, w can be reduced to 56~58dB from 80dB, greatly reduce
Domestic noise upstairs.This construction way reaches its maturity, in Beijing Olympic Garden residential project, Shenzhen Mangrove West Coast, Zhejiang gold
Magnificent sky dragon waits with setting has been all made of " floating build floor " construction in real estate projects, measured data fully meets requirements of the national standard,
Sound insulation effect is ideal.But above-mentioned floating floor is easy out in the presence of the concrete layer of floor clear height excessively, on vibration damping ground cushion is occupied
It splits, form the problem of string water layer between the concrete layer that vibration damping ground cushion is in contact with it.Meanwhile floating floor sound insulating layer is because being arranged in phase
On adjacent resident's platform, management and maintenance during being not convenient to use, upper floor resident, which often damages in fitment process, to be subtracted
Shake ground cushion.
Other than carrying out sound insulation processing in surface layer, in the recent period, the experiment that Tsinghua University's Architecural Physics laboratory carries out is ground
Study carefully and show that damping sheet can also be pasted in the lower surface of floor, the vibration of floor is damped, to improve oise insulation factor.Experiment
Show the hypodermis in 100mm thickness concrete ceiling, pastes that one layer of 25mm is thick to be prepared using special rubber and asphalt mixture
Damping sheet, and carry out plastering decoration processing after, strike note oise insulation factor can improve 7~10dB, can make concrete in this way
The strike note oise insulation factor of floor be up to state standards lower bound require Ln, w≤75dB.Damping sheet method is frequently utilized for can not be on floor
Surface carries out the situation of sound insulation processing.Damping sheet is pasted there are construction requirement height in the lower surface of floor, and damping sheet is adjacent thereto
Concrete and mortar material is incompatible, cohesive force is difficult to the problem of ensureing, damping sheet, which is easy to fall off, in use causes safety accident.
It can also be effectively improved floor sound insulation in addition, adding under concrete ceiling and hanging ceiling, floor is anti-after installing ceiling additional
Strike note sound pressure levels can be in 75dB or less.But adds to hang ceiling and equally exist and occupy that floor clear height is excessive and cost is high asks
Topic.
(2) floor insulation
In China, since the insulation level error of architectural exterior-protecting construction, the thermal efficiency of heating system are low.Relevant information table
Bright, China's unit construction area heating energy consumption is 3 times or so of developed country similar in weather conditions.National standard is " civilian to build
Build Thermal Design specification " and each Study on Climate Division of " public building energy design standard " and China energy Saving Design of Residential Buildings mark
After quasi- issuing and implementation, specific regulation is made that the thermal and insulating performance of floor.To reach thermal and insulating performance requirement, at present
Common practices is that floor upper surface is laid with or pastes one layer of thermal insulation thermal insulation layer, thermal insulation in lower surface after the completion of construction
Thermal insulation layer uses efficient and light weight thermal insulation material, such as EPS sheet, XPS plate, inorganic heat-insulation board, rock wool, mineral wool, heat preservation slurry.
Being laid with paste heat-preserving thermal insulation layer in slab surfaces, there are concrete adjacent thereto and mortar material that incompatible, cohesive force is difficult to protect
The problem of barrier, often leads to occur the quality problems of hollowing between insulating layer and mortar and concrete connecting place.
Efficient and light weight thermal insulation material, such as molded polystyrene foams plastics (EPS) plate, extrusion molding polystyrene polyfoam
(XPS) plate, phenolic board, polyurethane foam plastics plate, inorganic heat-insulation board, rock wool, mineral wool, concrete-based polyphenylene granule complex heat-preservation
Plate, heat preservation slurry etc. generally have the function of good thermal insulation property while having certain sound insulation sound insulation, are ideal
Heat preservation, heat-insulated, sound insulation acoustic material, but its generally there are intensity lower, surface and the poor problem of cement mortar cementitiousness.
Therefore, assembly concrete floor still has considerable room for improvement at present, and the present invention is formally based on above
It is insufficient and generation.
