Problems solved by technology
Reinforced concrete roof consists of steel bars and concrete to form a horizontal structural system. Disadvantages: 1. It does not conform to the development direction of energy conservation and environmental protection; 2. It increases the weight of the structure; the steel structure roof is made of steel structure and glass, pressed thin steel plate or other plates Constituting a horizontal structural system, disadvantages: 1. Can’t get on people; 2. Poor thermal insulation; grid roof is a horizontal structural system composed of steel grid and ALC board, glass, pressed thin steel plate or other plates, insufficient Disadvantages: 1. Can't get on people; 2. Poor thermal insulation

The invention provides a heat-insulating water-proofing accessible steel roof and relates to a novel construction structure, belonging to the technical field of construction; a horizontal H-shaped secondary purlin is fixedly connected on a main purlin, a net frame with a steel structure is arranged below the main purlin, a steel roof plate is arranged above the secondary purlin, and a cement ceramsite sloping layer, a cement mortar screeding layer, a main water-proofing layer, a polystyrene foam heat-insulating layer, an external water-proofing layer, a fine-stone concrete layer, a bonding layer and a veneering floor tile layer are sequentially arranged on the secondary purlin. By adopting the structure, the roof can bear dead load and live load of the roof and transmits to a wall column body, so as to realize the purpose of accessibility; the whole roof adopts high hot-resistance and water non-adsorbing material such as polystyrene plastics and the like as the heat-insulating layer, and the heat-insulating layer is arranged on the main water-proofing layer, so as to form a space roof system which has the advantages of heat insulation and longer service life of the water-proofing layer, and being energy-saving and environmentally friendly; in addition, the accessible steel roof has characteristics of long spanning, long column grid distance and large bay by systematically combining a reinforced concrete main structure.
Description
Technical field [0001] The invention relates to a new type of building structure and belongs to the field of construction technology. Background technique [0002] In the engineering structure, the existing building roofs are divided into: reinforced concrete roof, steel structure roof and grid roof. Reinforced concrete roof consists of steel and concrete horizontal structure system, shortcomings: 1. It does not conform to the development direction of energy saving and environmental protection; 2. The structural weight is increased; steel structure roof is made of steel structure and glass, profiled thin steel plate or other plates Composing a horizontal structural system, shortcomings: 1. No access to people; 2. Poor thermal insulation; the grid roof consists of a horizontal structural system composed of steel grids and ALC plates, glass, profiled steel plates or other plates. Places: 1. No access to people; 2. Poor thermal insulation. Summary of the invention [0003] The purp...
