Embodiment 1
[0022] Insulation of frame structures
[0023] (1) In the frame structure composed of beams, slabs and columns, multi-skinned first-stage autoclaved sand aerated concrete blocks are successively built until the frame structure is fully covered;
[0024] (2) Fill the joints between the top surface of the multi-skin first-stage autoclaved sand aerated concrete block and the beam plate with a polystyrene rod, and then beat the foaming agent to a predetermined height;
[0025] (3) brush interface agent on the concrete outer base of described beam slab and column, then install grid cloth on interface agent;
[0026] (4) After smearing anti-cracking mortar on the grid cloth and pressing it into the grid cloth for leveling, paste second-stage autoclaved sand aerated concrete blocks on the anti-cracking mortar with an adhesive, and build them on the grid cloth The bottom surface of the second-stage autoclaved sand aerated concrete block on the concrete outer base of the beam slab is ...

The invention discloses a method for constructing a self-heat preserving system structure, which comprises the following steps of: (1) sequentially building a plurality of first-stage autoclaved sand aerated concrete blocks in a frame structure consisting of beam plates and columns until the frame structure is filled with the blocks; (2) jointing at junctions of the top surfaces of the plurality of first-stage autoclaved sand aerated concrete blocks and the beam plates by using a polyphenyl rod, and applying a foaming agent to reach predetermined height; (3) brushing an interface agent on a concrete outer base layer of the beam plates and the columns, and arranging a mesh fabric on the interface agent; and (4) smearing anti-crack mortar on the mesh fabric, pressing in the mesh fabric, leveling, and adhering a plurality of second-stage autoclaved sand aerated concrete blocks to the anti-crack mortar by using an adhesive. By the method, the effects of containment filling, heat preservation and fire prevention are integrated; inner and outer additional heat-preserving layers are not needed; the self-heat preserving system structure constructed by the method has light weight and high accuracy and heat preservation and thermal insulation properties, and is environmental-friendly, plaster and labor are reduced, and the energy consumption of a building is reduced.
Description
technical field [0001] The invention relates to the field of self-insulation and energy-saving of building exterior walls, in particular to a wall structure integrating the three effects of enclosure filling, heat preservation and fire prevention of building exterior walls. Background technique [0002] In recent years, with the continuous deepening of my country's building energy-saving work and the continuous improvement of energy-saving standards, many new energy-saving technologies and materials have been introduced and developed, and their use has been vigorously promoted in buildings. Among them, various foam plastic insulation materials used in external wall insulation, such as EPS board, XPS board and foamed polyurethane board, have made great contributions to the implementation of the national three-step energy-saving standard. However, with the wide application of various external wall insulation materials, the fires caused by this are one after another. Therefore...
