As the global energy supply becomes increasingly tight, various countries are actively developing energy-saving and emission-reducing technologies with immediate effects while vigorously developing new energy technologies. Building energy consumption accounts for more than about 40% of the total social energy consumption, which does not even include energy consumed by building materials in production, transportation and construction processes. Technical development aimed at lowering building-related energy consumption has also become a major direction in the industry.
The most effective and most practical technologies of building energy conservation are external thermal insulation technologies for external wall, which are vigorously promoted and implemented in China right now. Thermal insulation needs to be applied on about 4 billion square meters of newly built buildings every year. In addition, there are about more than 40 billion square meters of existing buildings to be retrofitted for thermal insulation. Related state and local departments have also correspondingly formulated specific implementation standards and operational specifications.
Currently, there is a major difficult problem in the prior art, namely most external thermal insulation applications for external wall employ organic high performance foaming materials, which are combustible materials. If they are hit by open fire, they will be inflamed and it will be difficult to extinguish the fire. Although inorganic thermal insulating materials have excellent fire resistance performance, their thermal insulation property cannot meet the existing energy saving standards and requirements. Current external thermal insulation construction technologies for external wall are mostly layered construction, which makes it inevitable that the organic combustible materials will be exposed in certain periods. When they are hit by open fire (e.g. electric welding and the like), there is still a potential risk of fire.
One object of the present invention is to provide a novel prefabricated thermal insulating composite panel. Said prefabricated thermal insulating composite panel is prefabricated in a factory by combining an inorganic non-combustible material to the external side of the combustible thermal insulating material, which covers the core of the combustible thermal insulating material, thereby solving the problem of the tendency of causing a fire due to the exposed combustible material while storing, transporting or installing thermal insulation panels at a construction site or other places.
The technologies according to the present invention are as follows:
First Basic Technology
The first basic technology of the present invention relates to a prefabricated thermal insulating composite panel (1), which comprises an internal main surface (101), an external main surface (102), and four side end surfaces (103, 104, 105, 106), includes a core (9) made of the thermal insulation panel, and said prefabricated thermal insulating composite panel further comprises:
Two reinforcing protective layers (7) formed by cement-based or gypsum-based polymer-modified mortar; said core (9) is disposed between said two reinforcing protective layers (7), and said two reinforcing protective layers are bonded with said core (9);
A frame (2), said frame (2) surrounds the periphery of the core (9) and is fastened to the core (9), inside the internal main surface (101) and the external main surface (102) of said prefabricated thermal insulating composite panel, said reinforcing protective layers cover said frame such that said frame is exposed only at the four side end surfaces (103, 104, 105, 106) of said prefabricated thermal insulating composite panel, said frame (2) comprises two frame connection parts (11) at the external side of said frame and disposed at the top and bottom of the frame, respectively, and an installation groove (13) at the external side of said frame and disposed between said two frame connection parts (11), and said installation groove extends along the entire frame length.
The present invention has the following advantageous effects:
According to the prefabricated thermal insulating composite panel of the present invention, the core (9) is disposed between two reinforcing protective layers (7) formed by cement-based or gypsum-based polymer-modified mortar. As a result, on the product of prefabricated thermal insulating composite panel delivered by a manufacturing factory, the inorganic non-combustible reinforcing protective layers (7) have been used to cover the core (9) of the combustible organic material, achieving the effect that it is not easy to be inflamed. This fire-resistant effect is extraordinary either during transportation or at a construction site. In particular for the construction site, it is safer for piling or storage than the thermal insulating panels according to the prior art. Inside the internal main surface (101) and the external main surface (102) of said prefabricated thermal insulating composite panel, moreover, said reinforcing protective layers cover said frame (2). As a result, the frame is used to provide the integrity and strength for the composite panel and the installation groove on the frame is used to make it convenient for assembly. At the same time, said frame is exposed only at the four side end surfaces (103, 104, 105, 106) of said prefabricated thermal insulating composite panel. Consequently, an inorganic non-combustible material covers the combustible organic material to form an enclosed composite structure such that it will not be inflamed.
On the other hand, all of the thermal insulating materials according to the prior art are light and low strength materials, which are much lower than the strength of concrete forms, while the prefabricated thermal insulating composite panel of the present invention has a strength equivalent to that of construction concrete forms thanks to the composite reinforcing protective layers on the external sides. As a result, this composite panel not only has properties of a thermal insulating material, but also can be used as a concrete form that does not need to be detached (i.e. permanent concrete form), thereby integrating thermal insulating material installation and concrete form construction, eliminating the subsequent detachment of concrete forms and extra construction of a thermal insulating layer. It saves working procedures, saves materials, and in particular, saves a large quantity of wood. Therefore, the other object of the present invention is to provide a novel prefabricated thermal insulating composite panel. Said novel prefabricated thermal insulating composite panel adds reinforcing protective layers to both sides of the core of insulating material and adds a frame having an installation groove around the core, which, on one hand, improves the strength of the prefabricated thermal insulating composite panel and on the other hand, enables the assembly of the prefabricated thermal insulating composite panels by means of the installation grooves and embedding strips and/or tension connection parts that coordinate with the installation grooves, ensures the smoothness of external surfaces, realizes the assembly operation on construction sites, and improves the construction efficiency. With respect to this purpose, the material that forms the thermal insulating panel can be either an organic combustible thermal insulating material or an inorganic non-combustible thermal insulating material.
According to the statistics, the construction industry has become the largest user of wood in the industrial sector in China, which accounts for more than 70% of the wood consumption by the industrial sector. For example, the area of buildings under construction by real estate businesses of the whole country reached 3.084 billion square meters in the first half of 2010. If the ratio of construction area to concrete form area is 10:1, the 3.084 billion square meters of building will use 308.4 million square meters of concrete forms. If ⅔ of these concrete forms are wood concrete forms, then about 3.08 million cubic meters of wood (with the average thickness of concrete forms at 15 mm) will be consumed. In other words, we need to cut about 51.3 million trees, equivalent to about 730,000 mu of forest, to manufacture these concrete forms. If the prefabricated thermal insulating composite panel of the present invention is used as a permanent concrete form, the wood can be saved and the forest will escape destruction, and the environment will be protected. According to relevant sources, each hectare of forest can absorb about 16 tons of carbon dioxide and produces 12 tons of oxygen every year. Then, 730,000 mu of forest can absorb 780,000 tons of carbon dioxide and produces 580,000 tons of oxygen every year, which are potential environmental benefits by employing this technology only in the first half of 2010.
Moreover, the prefabricated thermal insulating composite panel of the present invention comprises a periphery surrounding the core (9) and a frame fastened to the core (9), the frame comprises two frame connection parts (11) at the external side of said frame and disposed at the top and bottom of the frame, respectively, and an installation groove (13) at the external side of said frame and disposed between said two frame connection parts (11), and said installation groove extends along the entire frame length. On one hand, the frame helps the provision of integrity for the thermal insulating composite panel and further provides strength. On the other hand, an installation groove is disposed on the frame to extend along its length. With the cooperation between a seamed connector and/or a seamless connector and the installation groove, therefore, the assembly of the prefabricated thermal insulating composite panels is very convenient, which can improve the construction efficiency. For the construction industry, this provides an efficient and rapid novel construction method.
If such a prefabricated composite panel with high structural strength, good thermal insulating property and fire resistant capability is used as permanent concrete form, its size is designed to be modular size, and an industrial frame of cold bend thin wall steel profiles is used as reinforcing bars (i.e. the skeleton of the entire concrete structure), an efficient and rapid integrated novel building system and construction method primarily consisted of composite panel splice, composite panel tension connection and concrete pouring can be developed.
When a cement-based polymer-modified mortar of Portland cement or magnesium oxychloride cement is used as the reinforcing protective layer and an organic thermal insulating material is used as the core, the fire-resistant effect will be more prominent.
The prefabricated thermal insulating composite panel of the present invention can have no decorative surface or have a decorative surface. If a decorative surface (15) is added to the external side of the prefabricated composite panel, the field construction operations can be reduced and the labor intensity may be lowered, which further improves the efficiency, shortens the construction period, and saves the cost.
Furthermore, the prefabricated composite panel of the present invention may be used in combination with the unique structure of the frame of cold bend thin wall steel profiles proposed in the present invention. Such a combination will form the concrete slab structural member of the present invention and the construction method thereof. In said concrete slab structural member, each longitudinal steel profile keel comprises two longitudinal cold bend thin wall steel profiles (951, 952; 851, 852), the main surfaces of said longitudinal cold bend thin wall steel profiles, the main surface of the concrete slab structural member, and the internal side main surface and external side main surface of the prefabricated thermal insulating composite panel or the prefabricated thermal insulating composite panel with a corner included in said thermal insulating composite panel structural assembly are parallel to each other, the two longitudinal cold bend thin wall steel profiles are spaced apart and opposite each other along a direction perpendicular to the main surface of the concrete slab structural member, so that a space (200) is left between the two longitudinal cold bend thin wall steel profiles, and therefore the concrete can easily flow through the space left between the two longitudinal cold bend thin wall steel profiles when it is poured. This avoids the problem created by the placement of the main surfaces of the cold bend thin wall steel profiles perpendicular to the main surface of the concrete slab structural member according to the prior art: 1) when concrete is poured between the external concrete form and the internal concrete form, the flowing of the concrete is hindered by the cold bend thin wall steel profiles, the concrete pouring efficiency is low, and the compactness and homogeneity of the poured concrete are affected; 2) the main surfaces of the cold bend thin wall steel profiles are perpendicular to the main surface of the concrete slab structural member, such that the cold bend thin wall steel profiles extend in the direction from indoor to outdoor and consequently form a cold bridge between the indoor and the outdoor, affecting the thermal insulating effect of the thermal insulating panel. By employing the novel structure of the frame of cold bend thin wall steel profiles, the concrete slab structural member according to the present invention solves the two problems in the prior art: 1) regarding the above problem 1), the longitudinal cold bend thin wall steel profiles of the present invention extend in the direction parallel to the main surface of the concrete slab structural member, and will not cause the same big hindrance as the prior art to the flowing of the poured concrete along the lateral extension direction of the concrete slab and along the concrete forms, and consequently the concrete can smoothly flow in the direction of the main surfaces of thin wall steel profiles. This can improve the pouring efficiency and ensure the compactness and homogeneity of the concrete that has been poured into the space between the internal and external concrete forms; regarding the above problem 2), the cold bend thin wall steel profiles of the present invention extend in the direction parallel to the main surface of the concrete slab structural member (perpendicular to the direction from indoor to outdoor), which avoids the formation of a cold bridge between the indoor and the outdoor.
When the prefabricated thermal insulating composite panel product, the prefabricated thermal insulating composite panel product having a corner and the frame structure product of cold bend thin wall steel profiles according to the present invention are combined, moreover, a complete building industry system will be formed. This system relates to building design and building structure, and moreover, relates to building construction. With an extensive application range, this system has the following advantages:
1. All products in this series are industrialized and standardized products, which can improve the resource utilization efficiency and ensure the product quality through large scale factory production, and turn the time-consuming field construction to factories. This completely complies with the state's development direction of housing industrialization.
2. Since the inorganic non-combustible material is compounded to the external side of the thermal insulating composite panel, the potential fire risk can be effectively eliminated in the transportation, storage and construction processes of these products.
3. When a reinforcing material, such as a reinforcing net formed by alkali-resistant glass fiber, carbon fiber or steel fiber, is added into the reinforcing protective layers of the inorganic non-combustible material on the external side, and/or chopped alkali-resistant glass fiber, chopped alkali-resistant carbon fiber or chopped alkali-resistant steel fiber is evenly distributed in said reinforcing protective layers, the bending strength of the composite panel is significantly superior to the bending strength of veneer plywood used as concrete forms, and can directly take the place of wood concrete forms on the external side of the surface that needs thermal insulation. The use of this form detachment-free technique not only makes the connection between the thermal insulating layer and the structural layer firm, but also eliminates the labor-consuming and time-consuming construction of thermal insulation, and further reduces the operations in conventional construction methods on detachment, maintenance, transport and final treatment of concrete forms.
4. When the prefabricated composite panel according to the present invention is combined with the frame structure of cold bend thin wall steel profiles according to the present invention to replace thread steel with cold bend thin wall steel profiles, the stability of temporary structure and accuracy of sizes are significantly improved without increasing the total steel consumption, such that the construction process is more convenient, rapid and reliable, and the use of temporary support is effectively reduced.
5. Due to the change of the construction method, the workload of field construction is greatly reduced, thereby saving labor, reducing work intensity, and shortening the construction period. As estimated, the application of the novel assembly technique for the building industry formed by the combination of the composite panel according to the present invention and the cold bend thin wall steel profile frame according to the present invention can save labor by 35%˜50% and shorten the construction period by more than 40%.
6. When concrete is poured between the permanent concrete form of the present invention and regular concrete form such that the concrete binds with the cold bend thin wall steel profile frame, a composite steel-concrete construction can be formed. The composite steel-concrete construction is one of the structures that are currently recognized to have the most excellent anti-earthquake, lasting and fire-resistant properties. Its anti-earthquake property is far better than the masonry structure, its fire resistant property and lasting property are far better than the steel structure, and its anti-earthquake and structural ductility are far better than those of the reinforced concrete structure according to the prior art.
7. When no concrete is poured, the structure formed by combining the prefabricated composite panel according to the present invention and assembly thereof with the cold bend thin wall steel profile frame according to the prior art can be used to build low lightweight steel buildings or rapidly assembled temporary buildings. In this case, galvanized steel sheets with good weather resistance should be used to make the cold bend thin wall steel profiles and water-proof structure should be constructed.
8. In applications with an existing substrate wall, the composite panel according to the present invention can be used as the product integrated with thermal insulation and decoration. The decorative surface layer can be made into a surface with stone, wood or metal texture. Fine aggregate concrete can be poured into the cavity to improve the structural strength and water-proof capability of the existing wall, which is particularly useful for renovation of old buildings.

Construction technologies based on an existing substrate wall—Construction technologies in preferred embodiments of the wall structural member of the present invention
The construction method in another preferred embodiment relates to a technology that adds the composite panels of the present invention to an existing substrate wall so as to perform decorative renovation, thermal insulation renovation or other renovation thereon. In said technology, the permanent concrete form of the present invention that includes the thermal insulating composite panel structure assembly or the prefabricated thermal insulating composite panel and/or the prefabricated thermal insulating composite panel with a corner that have been described above is used as the external thermal insulating layer and/or decorative layer. When the permanent concrete form has been installed, a desired filling material can be filled between the permanent concrete form and the existing substrate wall. For example, the filling of a thermal insulating material can further provide a thermal insulating capability to the wall. The filling of concrete can further provide strength and endurance to the wall. The filling of fine aggregate concrete can provide water-proof capability to the wall. Alternatively, space does not have to be left between the permanent concrete form and the existing several layers of wall.
