Problems solved by technology

The disadvantages of this insulation layer system are: high requirements on the flatness of the base wall; high overall cost; poor fire performance, poor environmental protection, and large limitations of exterior decoration (not suitable for bonding bricks), the most important thing is that it is windy near the sea The high-rise and super-high-rise residential buildings in the area are easy to fall off under the action of large positive and negative wind loads for a long time, and the safety is poor
However, there are stil

Abstract

The invention discloses an external thermal insulation board for an external wall and a construction method thereof. The method comprises the following steps: firstly, the external thermal insulation board for the external wall is prepared at first, including preparation of a fire-retardant polystyrene foam polyphenyl board, alternated arrangement of a plurality of rows of trapezoidal ash hanging tooth spaces on one side of the polyphenyl board, hanging of a steel wire net on the side face, and insertion of a bidirectional obliquely inserted steel wire on the polyphenyl board; secondly, the protruded surfaces of the obliquely inserted steel wires of a plurality of prepared external thermal insulation boards for the external wall are arranged inwards, and the obliquely inserted steel wires are arranged outside a tied wall reinforcement cage; thirdly, large external steel moulding plates are supported on the outside of the external thermal insulation boards for the external wall; and fourthly, concrete placing is performed and a template is disassembled. The external thermal insulation board for the external wall has light structural deadweight, low water absorptivity and good weathering resistance; compared with an applied thermal insulation board, the thermal insulation board is tightly and seamlessly bonded with walling, thereby a heat-insulation system is guaranteed to be not slipped and fallen down, not deformed, not cracked and not fallen off, and slab staggering of seams and deformation of the thermal insulation board can be effectively prevented. Moreover, the quality is easy to manage and control, and the construction speed is quick.

Description

technical field [0001] The invention relates to an external wall thermal insulation structure, in particular to an external thermal insulation board for an external wall built into a cast-in-situ concrete formwork and a construction method thereof. Background technique [0002] In recent years, with the continuous advancement of the country's three-step energy conservation, external wall thermal insulation technology has been widely used in civil buildings, especially high-rise and super high-rise residential buildings, and various thermal insulation systems have also been produced. As Dalian, Tianjin and other coastal areas are affected by sea winds and typhoons for a long time, the external wall insulation must not only meet the requirements for heat preservation, energy saving and safety, but also need to have the ability to withstand fatigue under large positive and negative wind loads for a long time . The commonly used method is the expanded polystyrene board thin pla...
