Embodiment 1

[0029] Embodiment 1: Taking a plate with a room size of 4800mm×3000mm as an example, the cooling pipe 5 is made of galvanized steel pipe. The galvanized steel pipes are machined in the factory with serpentine galvanized pipe meshes, and the cooling pipes 5 of each room panel correspond to four sets of galvanized steel pipe meshes, which are assembled on site. The size of the serpentine galvanized steel pipe mesh cooling pipe 5 is 3000mm×1200mm, that is, the length direction of the steel pipe is 3000mm. The total thickness of the plate ceramsite lightweight aggregate concrete 2 and the straw lightweight aggregate concrete 8 is 120 mm according to the requirements of thermal insulation performance and bearing capacity. At the position of the ring beam in the wall room where the masonry is completed, a connection inspection port is left, and a formwork is supported. The lower layer of steel wire mesh 7 is laid on the template, the steel wire diameter of the lower layer of steel ...

Embodiment 2

[0030] Embodiment 2: Taking a plate with a room size of 4800mm×3000mm as an example, the heat dissipation pipe 5 is made of polybutene pipe (PB). The cooling pipes 5 of each room board correspond to a group of polybutylene pipe (PB) mesh sheets, which are arranged in a serpentine shape on site. The heat pipe 5 in the whole room is not provided with a joint, and is connected with the heat pipe 5 in other rooms by setting a valve at the connecting inspection port, and the remaining parts are the same as in Embodiment 1.

Embodiment 3

[0031] Embodiment 3: Take a single-storey house as an example. After the lightweight aggregate concrete slabs in all rooms reach the design strength, the water inlet joint 1 of the heat dissipation pipe in the first room shall be connected with the corresponding joints of the system heating pipeline according to the design drawings; the first room slab The water outlet joint 3 of the inner heat dissipation pipe is connected with the water inlet joint 1 of the heat dissipation pipe of the second room plate by means of hot-melt joints. According to this method, according to the design requirements, the water outlet joint 3 of the heat dissipation pipe of the second room plate and the water inlet joint 1 of the heat dissipation pipe of the third room plate are connected by hot-melt joints until a circulation path connection is completed. In this way, the water inlet joint 1 of the plate cooling pipe in the first room is connected with the water supply pipe of this circulation pat...

Abstract

The invention relates to a lightweight aggregate concrete superposed slab integrating dual functions of load-bearing and heat radiation. The invention adopts the technical scheme that the lightweight aggregate concrete superposed slab comprises three stages: slab design, material processing and slab casting molding. Straw lightweight aggregate concrete is taken as upper-layer concrete for the slab, and lower-layer concrete adopts ordinary ceramsite lightweight aggregate concrete. After being subjected to overall pouring molding together with high-performance geothermal coils arranged in a snake shape or galvanized steel pipe meshes, the ceramsite lightweight aggregate concrete is superposed with the straw lightweight aggregate concrete on the upper layer, so that the straw lightweight aggregate concrete superposed slab integrating the dual functions of load-bearing and heat radiation is made. Each of heat radiation pipes in the slab has two functions of load-bearing and heat radiation; heat radiation pipe meshes not only are taken as tensile steel bars for the slab to jointly bear the load of the slab together with steel wires in steel wire meshes, but also are taken as the heat radiation pipes for a slab heat radiator, and the tensile steel bars and the heat radiation pipes are combined. The lightweight aggregate concrete superposed slab provided by the invention is simple to manufacture, convenient to mount and cost-saving and meanwhile has high comfort and an energy-saving effect.

Description

technical field [0001] The invention belongs to the technical field of civil construction engineering, in particular to a lightweight aggregate concrete laminated board with dual functions of load bearing and heat dissipation. Background technique [0002] Straw resources are abundant in northern my country, and the effective use of straw resources has increasingly become a topic of energy conservation, environmental protection and new rural construction. With the development of new rural housing construction and new urbanization construction in the cold regions of Northeast my country, the requirements for reducing housing construction costs and for housing comfort and energy saving are gradually increasing. The current residential slabs generally adopt cast-in-place concrete solid slabs or prefabricated reinforced concrete hollow slabs. Residential heating mostly uses coal-fired boiler rooms to provide heat sources, and radiators or geothermal pipes are used for low-tempe...
