The technique effect of a kind of light-duty plate of the present invention is:

1, the light-duty plate of first kind of structure of the present invention can alleviate floor weight 30~50%, and sandwich layer of the present invention is that common heat insulating material or light material on-site cutting get final product, even the locality does not have the die production producer light-duty floor of yet can constructing, construction install convenience, do not rely on the special hollow mould of making of hollowcore slab die production producer, the extensively universal condition that provides of large span floor is provided.

2, of the present invention second or the prefabricated light type composite panel weight of the third structure lighter, more about 60%~75% than the concrete roof plate weight reduction of 120mm~200mm thickness, the possibility of long-span roofing plate extensive use is provided.

Consider people's load and snow load on the roofing, second kind of the present invention, the third light-duty plate load least favorable combined value are 3.1KN/m 2Core layer thickness 100mm and 180mm, 250mm, with the of the present invention light type composite panel (press Q215 steel tensile strength design load) of 0.5mm steel plate as tensile reinforcement, can satisfy the curved designing requirement that is subjected to of 4.5m, 6m and 7m span simply supported slab respectively, can be widely used in the oblique roofing.

During by claim 3 of the present invention and 6 prefabricated production, the production line of the colored composite insulation boards of available production with polymer sandwich layer directly and steel plate bond, very convenient, raise labour efficiency, reduce cost.Particularly claim 4 and 7 is provided with topping in the steel plate bottom again, makes the fireproof performance of composite plate better.Claim 3 of the present invention and 6 bonds sandwich layer and steel plate with polyurethane foam glue pressurization bonding or with cement polymer mortar when cast-in-place.

In the time of need satisfying fire endurance 1h, claim 4 and the 7 bottoms protective layer thickness 25mm that plasters gets final product, and increases the bottom protective layer thickness and can increase fire endurance again, and upper protective layer thickness is not less than 20mm and is advisable; Claim 3 and 6 can satisfy the requirement of the roofing that is difficult for breaking out of fire.

Second kind of the present invention, the third structure only by increasing the force request that core layer thickness just can satisfy the long-span roofing plate, almost do not influence roof panel weight; And all be concrete roof panel when increasing concrete slab thickness, it is too many to gain in weight, and only designs pre-stress floor, otherwise freely-supported concrete slab that can not design 6m span.

3, cost is low.

Of the present invention second or the third structure when being applied to the roof panel of 3~4m span, the cost of claim 4 and 7 roof panel will be done the thermal-insulating waterproof engineering again than cast in place concrete plate and can reduce cost and be not less than 100 yuan/m 2, it is more to reduce cost than the large span insulation roof slab.Also can cancel roof truss in new countryside construction, longitudinal beam is set one in the middle of the house, the light type composite panel roofing of installation second or the third structure is because simple structure reduces cost significantly.

Since cancelled concrete slab, in light weight, owing to steel plate double as vapour barrier, waterproofing course, reduce the labour cost of multiple working procedures such as heat insulating work, waterproofing, so cost is low.Should be designed to simply supported slab, the steel plate between the prefabricated light type composite panel answers seaming to connect, and bottom and upper protective layer should be mended and be smeared connection; With polyurethane foam glue or other thermal-insulating sealing material seal, the top seam seals with the elastic water-proof fluid sealant at the bearing place, and this structure is highly beneficial to guaranteeing the reliable waterproof of roofing, and its waterproof durability is considerably beyond the durability of current waterproof coiled material.

Reliable layer by layer bonding is the necessary condition that second kind of the present invention, the third light type composite panel are set up.Sandwich layer and topping bonding and steel plate and topping bonding; should be " interfacial agents be used to plaster resistance split, increase and plaster and the job practices of veneer binding strength " by denomination of invention; the patent No. 200810063815.9, publication number are that my patent of invention of CN101215857A is constructed.Brushing interfacial agents again second time after the brushing first pass interfacial agents drying on sandwich layer or the steel plate, and plaster, with floated coat and sandwich layer bonding, and with floated coat and steel plate bonding thereupon, can guarantee the solid and reliable bonding of floated coat and sandwich layer, guarantee the solid and reliable bonding of floated coat and steel plate.Experimental results show that, knock with hammer and to destroy when plastering macromolecule EPS plate and cut a hole to such an extent that depression, cement mortar are comminution and destroy, but bonding interface still bonds, with 24h in the composite plate bubble entry after this destruction, put into the freezing 12h of refrigerator, take out again and dissolve, steep again in the entry, carry out multigelation experiment 50 times, bonding interface does not destroy, and bonding is described firmly, and floated coat freeze-thawing resistant and water proofing property satisfy instructions for use.Or first pass smears cement polymer mortar and steel plate or macromolecular material bonding, but still need brush second time interfacial agents when carrying out the topping plastering construction, the construction trouble, and the macromolecule adhesive consumption is big.Equally, interfacial agents also can reliably bond pea gravel concreten layer and steel plate, and the normal section intensity of bonding is greater than the concrete tensile strength value.

Although Germany's mask outside the EPS plate thin plastering body of wall of pasting the seventies destroys Under Repair, but think that the EPS plate of former stickup need not remove, only outer mask is removed, pasted the thick EPS plate of 100mm in the above again, this explanation is not subjected to the bonding adhesive durable years of ultraviolet ray irradiation to be no less than 60 years.The polyacrylate bonding adhesive is a durability best material in all bonding adhesive, plays an important role to prolonging the heat insulation system durable years.Light type composite panel of the present invention can reach and be not less than 60 years service life, and is safe and reliable.

For increasing the durability of light type composite panel, the steel plate in the light type composite panel should have erosion shield such as zinc coat.
