Description

Formwork-free composite heat-insulation sound-proof board
[ technical field ] A method for producing a semiconductor device
The utility model relates to a exempt from formwork compound incubation sound-proof board is applied to the building, especially in the assembly type structure, belongs to the building materials field.
[ background of the invention ]
As the country has vigorously developed the fabricated building, a large number of buildings using fabricated concrete structures are constructed. Fabricated floor slabs are one of the important components of horizontal members in fabricated buildings. At present, the fabricated floor mainly comprises two forms of fabricated concrete composite slabs and metal floor support plates.
Fabricated concrete composite slabs are integral flexural elements formed by post-casting concrete on top of a precast concrete slab at a construction site. The prefabricated concrete slab has the advantages that the prefabricated concrete slab is used as a template for pouring concrete on the top, a large number of temporary templates are saved, and all or part of template supports are saved. The prefabricated concrete laminated slab has the advantages that the whole slab is manually divided into two times along the thickness direction, the integrity is poor, meanwhile, the thickness of the assembled concrete laminated slab is generally not less than 120mm, the prefabricated part is not less than 60mm, and the post-cast concrete laminated layer is not less than 60 mm. The thickness of the floor slab is far larger than that of the floor slab of the traditional building by 100mm, and the construction cost is much higher; construction joints exist between the fabricated concrete composite slabs and the fabricated concrete composite slabs, and later-period shrinkage cracking is easy to occur; the prefabricated part of the fabricated concrete composite slab is difficult to be cut into blocks on a construction site, and the construction flexibility is poor; the thickness of the plate is generally within 150mm, the sound insulation and heat preservation performance is poor, the requirement of green buildings cannot be met, and sound insulation and heat preservation measures need to be additionally arranged on the plate surface or the plate bottom.
The metal floor slab is an integral floor slab formed by pouring and supporting the cast-in-place concrete on beams by using embossed thin steel plates as lining plates. The profiled sheet steel is used as a template for pouring concrete and is used as a permanent template, so that a large number of temporary templates are saved, and all or part of template supports are saved. The defects are that the fireproof and antirust capabilities of the profiled thin steel plate are poor; the metal floor support plate has poor sound insulation and heat preservation performance, cannot meet the requirement of green buildings, and needs to be additionally provided with sound insulation and heat preservation measures at the plate surface or the plate bottom.
The modern healthy habitable building has strict requirements on floor slab sound insulation and heat insulation:
floor slab sound insulation
Floor sound insulation is one of important factors for guaranteeing the environment of a house, but the importance of the floor sound insulation in the past building design is insufficient. With the increasing demand of people on the quality of houses and the gradual perfection of government-related living environment laws, the problem of floor slab sound insulation is highly emphasized in house design. The sound insulation of the floor slab includes the insulation performance against both impact sound and airborne sound. Generally speaking, it is not difficult to reach the air sound insulation standard of the floor slab, because the reinforced concrete material commonly used at present has better air sound insulation performance. According to the measurement, the air sound insulation single-value evaluation value of the reinforced concrete with the thickness of 120mm is about 50dB, if other construction measures are added, the effect is better, but the reinforced concrete with the thickness of 120mm is obviously insufficient for isolating impact sound. In commercial residences provided for consumers in the real estate market of China at the present stage, a large number of commercial residences are designed according to the initial assembly and repair standard, wherein the thickness of a floor reinforced concrete structure layer is generally 100-150 mm, a cement mortar leveling layer is arranged on the structure layer, and the weighting normalized impact sound pressure level of a floor slab is basically about 80 dB. If the wood floor is laid on the concrete floor when the householder carries out secondary decoration, the sound insulation of the floor slab is greatly improved, the solid wood floor and the composite wood floor have good impact sound insulation effect, the measured value is generally less than 70dB, and the requirement of the residential design standard on the low limit of the impact sound resistance of the floor slab is met. However, if the selected facing materials are hard materials such as granite, floor tiles, etc., the weighted normalized impact sound pressure level of the floor can only be maintained at about 80dB, which does not meet the specification requirement. The requirement of low limit of impact sound insulation single value evaluation quantity of various building floor slabs in the civil building sound insulation design specification GB50118-2010 is generally less than 75 dB.
For a reinforced concrete floor with a hard surface facing material, a popular method at present is a floating floor slab method, namely, a layer of damping ground mat with the thickness of 4-10 mm is paved on a structural floor slab, and then concrete with the thickness of 40-80 mm is poured on the damping ground mat and reinforcing steel bars are arranged in the damping ground mat to form a sandwich elastic sandwich structure. According to the detection conclusion of a building physics laboratory of Qinghua university, the weighted impact sound pressure level improvement quantity delta Lw of the vibration-damping floor type floating floor can reach 22dB (the specific numerical value is related to the material and elasticity of a floor mat) compared with the original concrete floor, the impact sound insulation quantity Ln and w can be reduced from 80dB to 56-58 dB through field actual measurement, and the living noise on the floor is greatly reduced. The construction method is mature day by day, the 'floating floor slab' structure is adopted in real estate projects such as Beijing Olympic Garden, Shenzhen Reynesha, Zhejiang Jinhuatianlong land and the like, the measured data completely meets the national standard requirements, and the sound insulation effect is ideal. But above-mentioned floating ground exists to occupy the clear height of floor too much, the concrete layer on the damping ground mat is easy to ftracture, damping ground mat and the concrete layer rather than the contact form the problem of cluster water layer between. Meanwhile, the floating ground sound insulation layer is arranged on the ground platforms of adjacent households, so that the management and maintenance in the use process are not convenient, and the households on the previous floor often damage the vibration reduction ground mats in the decoration process.
In addition to the sound insulation treatment on the surface layer, recent experimental research carried out in the building physics laboratory of the university of qinghua shows that a damping plate can be adhered to the lower surface of the floor slab to damp the vibration of the floor slab, thereby improving the sound insulation. Experiments show that after a damping plate which is 25mm thick and is prepared by specially-made rubber and asphalt mixture is pasted on the lower skin of a concrete ceiling with the thickness of 100mm and is subjected to plastering decoration treatment, the impact sound insulation can be improved by 7-10 dB, and the impact sound insulation of the concrete floor can reach the national standard low limit requirement Ln by adopting the method, wherein w is less than or equal to 75 dB. The damping plate method is often used in situations where sound insulation treatment cannot be performed on the upper surface of the floor. The lower surface of the floor slab is pasted with the damping plate, so that the construction requirement is high, the damping plate is incompatible with adjacent concrete and mortar materials, the cohesive force is difficult to ensure, and the damping plate is easy to fall off to cause safety accidents in use.
In addition, the sound insulation of the floor can be effectively improved by additionally hanging the ceiling under the concrete ceiling, and the sound pressure grade of the anti-collision sound of the floor after the ceiling is additionally arranged can be below 75 dB. But the ceiling with the hanging also has the problems of excessive floor occupation and high manufacturing cost.
Floor slab heat preservation and insulation
In China, the building envelope structure has poor heat insulation level and low heat efficiency of a heating system. The related data show that the heating energy consumption of the unit building area in China is about 3 times of that of developed countries with similar climatic conditions. After national standards of civil building thermal design standards and public building energy-saving design standards and residential building energy-saving design standards of each climate partition in China are issued and implemented, clear regulations are made on the heat preservation and heat insulation performance of the floor slab. In order to meet the requirements of heat preservation and heat insulation performance, the upper surface of a floor slab is paved or an additional heat preservation and insulation layer is stuck on the lower surface of the floor slab after construction is finished, and the additional heat preservation and insulation layer is made of light high-efficiency heat preservation materials such as EPS boards, XPS boards, inorganic heat preservation boards, rock wool, glass wool, heat preservation slurry and the like. The problems that the heat-insulating layer is laid and adhered on the surface of the floor slab, the concrete and mortar materials adjacent to the heat-insulating layer are incompatible, and the bonding force is difficult to ensure often result in the quality problem of hollowing between the heat-insulating layer and the joint of the mortar and the concrete.
Light high-efficiency heat-insulating materials, such as molded polystyrene foam plastic (EPS) plates, extruded polystyrene foam plastic (XPS) plates, phenolic boards, polyurethane foam plastic boards, inorganic heat-insulating boards, rock wool, glass wool, cement-based polystyrene particle composite heat-insulating boards, heat-insulating slurry and the like, generally have good heat-insulating performance and certain sound-insulating and sound-insulating functions, are very ideal heat-insulating, sound-insulating and sound-insulating materials, but generally have the problems of low strength and poor surface and cement mortar bonding capacity.
Therefore, the present fabricated concrete floor still has a great improvement space, and the utility model discloses it is just based on above not enough and produce.
