the utility model relates to a building roof structure, especially a pin-connected panel room lid of building engineering construction technical field's building.

Background art:

the annual production amount of industrial byproduct gypsum in China is about 1.84 hundred million tons, and the accumulated stockpiling amount exceeds 5 hundred million tons. But the comprehensive utilization rate of the newly increased production amount is only 48.1% every year, and the unused part can be only stocked in the open air. A large amount of gypsum waste residues are piled up, namely, a large amount of land is occupied; secondly, the investment of a storage yard is large, the operation cost is high, and the volume of the storage yard and the anti-seepage treatment requirement of the foundation are strict; thirdly, precious sulfur resources are wasted; and the contained acidity and other harmful substances are easy to cause pollution to the surrounding environment, and are not qualified with the environmental protection policy advocated by the state. The industrial by-product gypsum is an important regenerated gypsum resource, the main component of the industrial by-product gypsum is calcium sulfate (CaSO4 & 2H2O), the industrial by-product gypsum is an excellent cementing material, has the technical characteristics of early setting and quick hardening, fire resistance and energy conservation, is harmless to human bodies, and is suitable to be used as indoor decorative materials including wall materials. But at present, the cement retarder, the paper-surface plasterboard and the like are mainly used, the utilization amount is saturated, and the rising space is limited. Therefore, the development of gypsum as an industrial by-product for use in other fields of building materials is urgently needed. At present, the country has vigorously advocated prefabricated building house technology, including prefabricated concrete structure, prefabricated steel construction, prefabricated timber structure. However, the traditional rural self-building house mainly adopts a brick-concrete structure and a concrete frame structure, the wall materials of the house mainly adopt red soil bricks, hollow bricks, cement bricks or earth blank bricks as the wall materials, and the roof materials are generally flat concrete floors, so that the house has the defects of poor earthquake resistance, poor heat insulation, low construction speed, low work efficiency and high labor cost.

The low-layer cold-formed thin-wall steel house is a novel building technology of self-built houses in rural areas in recent years, the adopted materials are green building materials, the steel structure materials can be recycled by 100%, and other matched materials can also be mostly recycled, so that the ecological environment requirement is met, and the health is facilitated. Particularly, the dry operation construction mode is adopted, so that the pollution of wastes to natural environments such as rural land, rivers and the like can be reduced, and the current environmental protection consciousness is met. The pitched roof structure is mostly a truss or a pitched beam, an OSB plate, a waterproof material and a roof tile are paved on the pitched roof structure, and a heat insulation material is paved in the truss in an inclined mode or is paved on a top layer suspended ceiling in a flatwise mode. The sloping roof has the ventilation function, can make the inside sky of room form between the air that flows, guarantees the inside ventilation and the heat dissipation demand in roof. But the disadvantages are temperature and sound insulation, and the installation of a top ceiling is necessary.

The utility model has the following contents:

the utility model aims to solve the technical problem that a pin-connected panel room lid is provided. On the premise of fully utilizing industrial byproduct gypsum, the formed roof cover with a certain inclination angle is divided into three parts which are respectively built and combined and spliced together in construction, so that the problems of heat preservation, sound insulation, fire prevention, water prevention, safety and environmental protection of the roof cover body are solved.

Therefore, the utility model solves the technical scheme of problem is: a sectional roof having three separate structural units: the roof tile waterproof layer is composed of roof tiles, a waterproof layer, wood boards, tile strips and screws; the C-shaped steel hollow layer is composed of a sheet-shaped cold-formed thin-wall C-shaped steel 21, a polymer waterproof anti-cracking mortar layer 22, an alkali-resistant mesh cloth 23, a cement mortar layer 24, an upper steel wire mesh 25, a hollow layer 26, a lower steel wire mesh 27 and a gypsum mortar layer 28; the inclined beam and the truss member are made of cold-formed thin-walled steel; the roof is characterized in that the C-shaped steel hollow layer is arranged between the roof tile waterproof layer and the oblique beam and truss members, and the three independent structural units are assembled to form a complete roof.

Furthermore, the waterproof layer in the roof tile waterproof layer is composed of a waterproof coil layer or a coating waterproof coating layer, is arranged below the tile strips, and is connected with the C-shaped steel in the C-shaped steel hollow layer through screws.

Further, a polymer waterproof anti-crack mortar layer in the C-shaped steel hollow layer is arranged above the battens.

Furthermore, an upper steel wire mesh in the C-shaped steel hollow layer is arranged below the cement mortar layer.

Further, lower floor's wire net setting in the hollow layer of C shaped steel is in the top on gypsum mortar layer.

Compared with the prior art, the utility model discloses the positive effect of production is: the assembled roof is formed by connecting independent construction units of a roof tile waterproof layer, a C-shaped steel hollow layer, an oblique beam, a truss member and a light steel keel wall through connecting pieces, and simple and easy convenience is provided for reconstruction and reconstruction of a house; the integral roof adopts a large amount of gypsum-based materials to absorb the byproduct gypsum in the process, thereby fully embodying the effects of environmental protection consciousness and strengthening energy conservation and emission reduction. In the face of the building market, the assembled roof can be used for not only transforming and replacing the roof structure of the existing building, but also embodying the comfort advantages of the house being warm in winter and cool in summer in the application effect.
