Wall body heat insulating construction method

Abstract

The present invention discloses a wall body heat-insulating construction method. Said method includes the following main construction steps: firstly, making heat-insulating form and its support, binding steel bar of base wall body, supporting general form at inside of basewall body position, and placing support, then placing heat-insulating form embedded stay bolt at outside of base wall body position, placing wood square at outside of heat-insulating form, placing steel pipe at outside of wood square, concreting, after the concrete is formed, repairing heat-insulating form and making surface treatment, using grooving machine to cut recessed groove on heat-insulating form to make dividing seam, brushing interfacial agent, applying first layer of polymer mortar, laying grid fabric, applying second layer of polymer mortar, finally making surface construction.

Problems solved by technology

[0002] At present, there are many construction methods for building wall insulation: for example, the sandwich insulation wall is a truss made of steel mesh sandwiched in four directions and three-dimensionally intersected in four directions. The steel mesh sheets on both sides are welded into grid panels, and concrete is poured on both sides. Forming a composite shear wall, the disadvantage of this construction is that it changes the wall structure greatly, and the structural performance requires a large number of experiments and demonstrations. The construction technology is quite different from the traditional technology, and it is difficult to popularize; : Unable to achieve one-sided thermal insulation, great changes to the traditional shear wall structure, poor applicability, etc.; the disadvantage of the modular thermal insulation formwork is that it cannot achieve single-sided wall thermal insulation, and the amount of thermal insulation materials is relatively large, occupying indoor space , the structural performance must be tested, and the reinforcement is more difficult than the block-type thermal insulation formwork system, and the applicability is poor; the disadvantage of the improved modular formwork system is: because there are a considerable number of folding hooks in the module, steel mesh is set outside the module , in addition to setting a few structural columns and beam reinforcement, it is difficult to configure other stress reinforcement inside the module, so it is difficult to meet the requirements of domestic structural design codes in terms of reinforcement)

The shortcoming of the built-in large formwork is that the shaped large steel formwork must be used outside the thermal insulation formwork; the shortcoming of the most commonly used post-insulation method of the thermal insulation formwork is that the thermal insulation construction must be carried out after the main structure is completed, and the construction is greatly affected by the climate. It is difficult to guarantee the construction period, etc.
