Description

A kind of sound-heat insulating compound floor slab
Technical field
The utility model relates to a kind of acoustical and thermal composite building floor.
Background technology
In recent years, about 1,000,000,000 square metres of the average annual completed floor space of national building construction, the overwhelming majority is cast-in-place solid concrete floor.Not only material is wasteful for cast-in-place solid concrete floor, the heat insulating and sound insulating performance is also poor, upstairs voice is irksome invariably clearly under the sound moved of rub-a-dub rub-a-dub footsteps and object and neighbours, the upstairs house, is that the resident complains and complains one of maximum dwelling house performance.The contradiction of Yin Faing is increasing therefrom, has become a kind of problem of social concerns.
Flooring is transaudient, and to belong to vibration transaudient, mainly is that flooring produces the bump chatter, propagates along the rigidity joint face of building structure, and last vibrational structure forms air to receiving space radiation, passes to the recipient.Its sound insulation approach has three measures: the vibration weakening that the first causes vibration source bump floor, but be difficult in practice generally be suitable for.It two is to intercept vibrational structure to the air that receives space radiation, and this does the sound insulation furred ceiling at underfloor usually and solves, and furred ceiling will seal, and is connected with elasticity with floor, also can't popularize with taking up room from cost, and defening effect is limited.Its three obstructs vibration propagation in floor structure, promptly we build flooring at said floating, and it is to lay one deck vibration damping sound insulating material on the flooring of building, and does bed course and decorative cover then thereon again.Elastic damping soundproof course between this floor basic unit and ground surface layer, can produce damping effect to the bump vibration that the ground surface layer produces, have and reduce the noise of basic unit's floor, reach the purpose that improves floor impact sound sound insulation property, be used on the engineering now to radiation downstairs.But its construction is all carried out at the scene, and operation is many, and the cycle is long, and site environment is poor, is not suitable for modernized construction requirement.
Along with air-conditioning and heating are more and more adopted in building construction, also more and more higher in addition to the heat insulation requirement of floor, and the existing floor of China is not considered heat-proof quality substantially.
The utility model content
The technical problems to be solved in the utility model provides a kind of sound-heat insulating compound floor slab, has good sound insulation and heat-proof quality.
In order to address the above problem, the utility model provides a kind of sound-heat insulating compound floor slab to comprise: sheet-metal layers, rock wool flaggy, waterproofing course, stress dispersion layer and layer of concrete, described sheet-metal layers, rock wool flaggy, waterproofing course, stress dispersion layer stack gradually with layer of concrete is in the same place.
Preferably, described metal level is dark rib type profiled sheet or shallow rib type profiled sheet.
Preferably, described rock wool flaggy is resistance to compression high density rock cotton board, structure rock wool, granular rock wool, structural glass face, molding polyphenyl, extruded polystyrene or polyurethane.
Preferably, waterproofing course is polyethylene polypropylene waterproofing materials, terylene (FS2) waterproofing materials, polyethylene flexible geo-membrane or modified bitumen SBS etc.
Preferably, described stress dispersion layer is galvanized steel wire netting or muscle wire lath sheet is arranged.
Preferably, be provided with overlay coating between described rock wool flaggy and the waterproofing course, overlay coating is bonded on the described rock wool flaggy by cementing agent.
Preferably, the selected surface lining of described overlay coating is kraft or the kraft that is compounded with the aluminium pool; Described cementing agent is mono-component polyurethane glue or bi-component polyurethane ester gum.
The utlity model has following advantage:
1, the performance indications of the utility model product: air sound insulation factor ≮ 65dB; Impact sound is arbitrarily downgraded＜55dB; Therefore coefficient of thermal conductivity ≯ 0.3W/mK has good sound insulation, effect of heat insulation;
2, the utility model is by being provided with the stress dispersion layer, eliminates effectively or prevented issuable inter-laminar stress, guaranteed the stability of floor performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises: sheet-metal layers 5, rock wool flaggy 4, waterproofing course 3, stress dispersion layer 2 and layer of concrete 1, sheet-metal layers 5, rock wool flaggy 4, waterproofing course 3, stress dispersion layer 2 stack gradually with layer of concrete 1 is in the same place.
Sheet-metal layers 5 is zinc-plated profiled sheet, and certainly, also can adopt is color steel profiled sheet.Steel plate thickness can be 0.8～1.2 millimeter, and width is 1000～1200 millimeters, and the effective width after the moulding is 688 millimeters～755 millimeters, and sloping height is 75 millimeters.1.0 millimeters of the preferred steel plate thickness of the utility model, width is 1000 millimeters, and the effective width after the moulding is 688 millimeters, and sloping height is 75 millimeters.
Rock wool flaggy 4 is resistance to compression high density rock cotton board, structure rock wool, granular rock wool, structural glass face, molding polyphenyl, extruded polystyrene or polyurethane.
The waterproofing materials that waterproofing course 3 adopts has polyethylene polypropylene waterproofing materials, terylene (FS2) waterproofing materials, polyethylene flexible geo-membrane, modified bitumen SBS etc.
Stress dispersion layer 2 is for galvanized steel wire netting or muscle wire lath sheet is arranged.By the peptizaiton of stress dispersion layer 2, reduction external force is applied to the load on the unit area, plays the effect of protection asbestos product.Again because the multilayer material that the utility model adopts is compound, the performance of various materials (as coefficient of expansion etc.) is widely different, if can not effectively eliminate the stress that produces and prevent issuable interlayer, then may make certain one deck (as waterproofing course 3) of product be destroyed and make the decline of the utility model performance or the lost of life.Therefore,, effectively eliminate or prevent issuable inter-laminar stress, guaranteed the stability of floor performance by waterproofing course 3, adhesive and stress dispersion layer 2.
In addition, be provided with overlay coating between rock wool flaggy 4 and waterproofing course 3, overlay coating is bonded on the rock wool half storey 4 by cementing agent.The selected surface lining of overlay coating is kraft or the kraft that is compounded with the aluminium pool; Cementing agent is mono-component polyurethane glue or bi-component polyurethane ester gum.
Layer of concrete 1 is cast on the stress dispersion layer 2 by the mode of pouring.
Concrete preparation technology is as follows:
Step 1, with the hot-galvanized steel plate development of wide 1000mm, thickness 1.0mm after be cut into the long plate of 3.0M behind the milling train die mould, make sheet-metal layers 1, spray mono-component polyurethane glue then in the above, follow the high density of lay resistance to compression in the above rock cotton board, form rock wool flaggy 2, the unit weight of resistance to compression high density rock cotton board is 120kg/m 3, thickness is 75mm, coefficient of thermal conductivity is 0.043w/m.k; Spray glue again on resistance to compression high density rock cotton board, the kraft that will cut covers on the rock cotton board at last, and pressurization, curing are stand-by.The effective width of this example plate is 688mm, and thickness of slab is 75mm, and the slope height is 76mm.
Step 2, load onto waterproofing course 3 on the kraft upper berth, the material that discharges water adopts modified bitumen SBS;
Step 3: fixed stress dispersion layer 4 on the layer 3 that discharges water, stress dispersion layer 4 adopts galvanized steel wire netting;
Step 4: on stress dispersion layer 4, pour reinforced concrete floor 5.
