Embodiment 1

[0017] Embodiment 1: Taking the manufacture of a roof panel with a size of 2400mm×800mm as an example, the thickness is 250mm according to the requirements of thermal insulation performance and bearing capacity. First make the straw sandwich layer 6 with a thickness of 190 mm, cut to size, sprinkle a small amount of water on the straw sandwich layer 6 for wetting treatment, and smooth the surface, and trim the corners of the straw sandwich layer neatly. After the straw sandwich layer 6 is slightly dry, a steel wire mesh 5 is laid on both sides thereof. The steel wire diameter of the steel wire mesh 5 is 3mm, and the grid size is 12mm×12mm. At the same time, vertical steel wires 7 with a length of 200 mm and a diameter of 3 mm are welded and fixed, and the distance between the vertical steel wires 7 is 200 mm. After the vertical steel wire 7 is welded and fixed, the upper and lower spacing of the steel wire mesh 5 is 200mm. In the lower part of the steel wire mesh 5, the heat ...

Embodiment 2

[0018] Embodiment 2: Take a single-storey house as an example. After the wall construction is completed, the ring beam concrete is poured to complete the flat opening and leveled with cement mortar. The straw roof panels with heat dissipation function brought into the construction site are hoisted on the wall in sequence. The water outlet joint 3 of the roof panel heat dissipation pipe of the first straw roof panel with heat dissipation function is connected with the water inlet joint 1 of the roof panel heat dissipation pipe of the second straw roof panel with heat dissipation function by hot-melt joints. According to this method, according to the design requirements, the water outlet joint 3 of the roof panel heat dissipation pipe of the second straw roof panel with heat dissipation function and the water inlet joint 1 of the roof panel heat dissipation pipe of the third straw straw roof panel with heat dissipation function are hot-melted. Way joints are connected until a c...

Embodiment 3

[0019] Embodiment 3: Take the winter heating of newly built single-storey houses in rural areas in the north as an example. The heat source of the heating system is in the form of a small water source heat pump, and the water supply temperature is 42°C. The rice straw roof panel with heat dissipation function is used for heating, and the indoor temperature is kept above 18°C. The indoor temperature is measured at heights of 0.5m, 1.0m, and 1.5m from the roof, and the temperature difference is 0.2-0.3°C, which is relatively small, so it is very comfortable to use this roof panel to achieve heating. The roof panel radiates from top to bottom to adjust the temperature, no wind or air flu, and the temperature is uniform. The heating system is set on the ceiling, which does not occupy the indoor space and the effective use area of ​​the room, and the effect is excellent.

Abstract

The invention discloses a straw stalk roof panel with the heat dissipation function. According to the technical scheme, a proper width and length of the roof panel are selected according to the room design of a construction drawing; pipe diameters and the distance between pipes are determined according to the water supply temperature and the flow in unit time; high-performance engineering plastic pipes are bound on a steel wire net of the straw stalk roof panel, pipeline connectors are reserved on the two sides of the roof panel, and different heat dissipation pipes of the roof panel can be connected through the reserved connectors according to the requirements of different circulating paths; fine aggregate concrete is sprayed, the straw stalk roof panel and the heat dissipation pipes are integrally prefabricated, and the thickness of the roof panel is 30 mm. The roof panel and a radiator are integrated, manufacturing is easy, installation is convenient, and manufacturing cost is reduced; meanwhile, the straw stalk roof panel is comfortable and capable of saving energy.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, in particular to a rice straw roof panel with heat dissipation function. Background technique [0002] In the construction of energy-saving residential buildings in new rural areas in the northern severe cold area, the roof panels are usually cast-in-place or prefabricated concrete panels, and the upper part is made of EPS panels for insulation; there is also a kind of purlin laying wooden board base layer covered with thermal insulation materials, and the outer layer is made of slopes such as cement tiles or clay tiles. Roof form; or adopt the form of sloping roof with pressed color steel plate and built-in EPS board. The heating method in the residential room is mainly based on ordinary radiator heating, and some use PE pipe floor radiant heating, ceiling electrothermal film heating and other methods, and a few use new low-temperature radiant ceiling heating. The above h...
