The prefabricated structural element can be used as a non-bearing wall plate or a bearing wall plate, the integral shock-resistant property of the building is improved, and the utility model is suitable for factory production and can avoid the field wet work.

Description

The prefabricated sandwich wall board of light thermal-insulation

The utility model relates to a kind of prefabricated structural element of building construction inner, external wall and the use of other similar applications.

For a long time, the materials for wall of China is loam brick more than 80%, about 6,000 hundred million standard bricks of annual production, and about 1,200,000 mu in consumption soil, 6,000 ten thousand tons of mark coals consume energy.Moreover, and the manufacturing process complexity, the cycle is long, and breakage is many, and labour intensity is big, and social economy's property is poor.

In the building construction, once adopted a kind of prefabricated panel member (being commonly called as large panel structure) that constitutes with cage of reinforcement and layer of concrete, the coated whole skeleton of layer of concrete, the two sides, front and back of the cage of reinforcement that promptly is laid in and four peripheries.This is the structure that skeleton and layer of concrete constitute with the plain bars, and the most outstanding drawback is that own wt is big, steel quantity consumption is big, and insulation, soundproof effect are poor, also occur the crack easily, leak, combination property and of poor benefits.In recent years usefulness seldom is tending towards superseded.

After the seventies energy crisis, countries in the world are paid attention to the research and development of energy-saving building material more.In numerous energy saving building goods, the composite board system is with its excellent performance, and cheap price is developed rapidly.As disclosed prestressed reinforced concrete roof panel in ZL99205102.9, disclosed prestressed reinforced concrete combined type floor among the ZL99205103.7, they successfully adopt in light weight, intensity is high, the steel wire net rack sandwich sheet of high insulating effect and compressor wire, layer of concrete are made respective members, has good result of use as roof panel, floor.But be subjected to the restriction of its structure, this have prestressed member not use as wallboard.

The purpose of this utility model is to avoid the deficiencies in the prior art part, and provides a kind of from heavy and light, the prefabricated sandwich wall board product of light thermal-insulation that performance is good.

Can take following technical scheme to realize purpose.

The prefabricated sandwich wall board of light thermal-insulation contains skeleton and layer of concrete, and skeleton is the steel wire net rack sandwiched plate, the be laid in two sides, front and back of steel wire net rack sandwiched plate of layer of concrete.

The prefabricated sandwich wall board of light thermal-insulation is to be prefabricated in the factory into wall plate member, is transported to the construction site, deposits, lifts, installs through special equipment.Be connected with agent structure such as post, beam and floor when mounted; it installs piece need be incubated waterproofing work; thereafter do exterior wall surface decorative and interior wall decoration, inside and outside metope decorative layer also can be at produce in factory, but needs note at transportation, lifting, erection stage the protection of finish coat.

Under the prerequisite that satisfies the said structure requirement, in the prefabricated sandwich wall board of light thermal-insulation, the steel wire net rack sandwiched plate can adopt the goods of commercially available various existing product or other form of structure, and its central layer can be flame-retardant polystyrene plastic foamboard, rock cotton board or other light heat insulation material; Layer of concrete can be light weight concrete construction, general cement mortar or pea gravel concreten.Specific constructive form, size as for steel wire net rack, the steel wire in length and breadth of upper and lower net sheet, the specifications and models of oblique inserted wire, the diameter thickness of other position silk, the shape of grid, the spacing size of upper and lower net sheet and central layer, the shape of central layer, thickness, the material of selecting for use, the thickness of layer of concrete etc. all can be according to using needs to take the circumstances into consideration to set.They can both realize its intended purposes of this product, guarantee its functional performance and effect.

The relative prior art of the technical program has following advantage and effect:

The prefabricated sandwich wall board of light thermal-insulation from heavy and light, both can be made into non-bearing wallboard, also can be made into load-bearing wall panel, and the overall performance of building construction, anti-seismic performance are improved; Heat preservation and soundproof is effective, is fit to batch production production; Construct simple and direct, be convenient to install, can avoid the situ wet operation; Cost is low, combination property is preferable, social benefit, good in economic efficiency, this product with at ZL99205102.9, disclosed prestressed reinforced concrete roof panel, floor organically combine and can replace traditional brick-and-concrete buildings among the ZL99205103.7, to save soil, energy-saving and environmental protection have great and profound significance, be worthy of popularization.

The Main physical performance of this wallboard: thermal resistance 0.67-1.84m ²K/W, sound insulation 40-52dB, fire endurance is more than 2 hours, and frost resistance is more than 25 times.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of section of structure of the prefabricated sandwich wall board of light thermal-insulation;

Fig. 2,3 is respectively that other of the prefabricated sandwich wall board of light thermal-insulation plants section of structure.
