Abstract

The invention provides an energy storage and thermal insulation building structure. The building structure successively comprises an interior facing layer, a first anti-fracture layer, a first thermalinsulation mortar layer, a masonry layer, a second thermal insulation mortar layer, a second anti-fracture layer and an outer facing layer from inside to outside. The masonry layer is formed by blocks and masonry mortars which fill between the blocks; the blocks comprise hollow blocks and phase change mortars which fill the interiors of the hollow blocks. The energy storage and thermal insulationbuilding structure contains phase change materials which can improve thermal inertia, increase heat storage capacity, delay indoor peak temperature occurrence time and reduce indoor temperature fluctuation. The experimental results of examples show that, compared with an ordinary building structure, the temperature fluctuation in experimental rooms formed by the energy storage and thermal insulation building structure is reduced by 6 DEG C or above, and the maximum temperature is delayed by 28 min or above, and the energy storage and thermal insulation effect is very remarkable.

Description

technical field [0001] The invention relates to the technical field of building heat preservation, in particular to an energy storage and heat preservation building structure. Background technique [0002] At present, the walls are mainly divided into brick walls and aerated concrete block walls. The brick wall is made of ordinary clay bricks, clay porous bricks, clay hollow bricks or scorched bricks to form the main structure of the wall, and the aerated concrete block wall is made of aerated concrete blocks to form the main structure of the wall. Then plaster a layer of leveling mortar layer on the main body structure of the wall, and then smear the finishing paint on the leveling mortar layer. Although the traditional wall has a certain thermal insulation performance, the energy storage capacity of the wall is extremely limited. Most of the walls are mainly heat preservation and heat insulation, and few walls involve energy storage. Even if the traditional wall has a c...
