Description
Technical Field
The invention relates to the technical field of building construction, in particular to a construction method for preventing a joint of a built-in heat-insulation shear wall and a filler wall under a window from cracking.
Background
Because of the influence of various factors such as the structural form of a building, climatic conditions, system materials, construction process, construction management and the like, even the most mature heat insulation system can generate a series of quality problems after engineering, wherein the problems of cracking and hollowing of the heat insulation system are more prominent, the heat insulation system can affect the appearance slightly, and the heat insulation system can seep water and fall off to lose the energy-saving effect and shorten the service life of the building. In the fracture treatment method, the following three treatment methods are generally used: the first is that after the heat preservation layer is cleaned, a layer of dacron cloth, kraft paper or newspaper is stuck, and the integrity of the surface layer is ensured by using the tension of the fiber; the method is simple and easy to implement, but has a common effect. The second is to remove the heat-insulating board, install a layer of gypsum board or five centimetre boards outside the heat-insulating layer, and then make latex paint; the method can effectively remove cracks, but has higher cost and great construction difficulty; and the third method adopts elastic putty to be coated at the crack, so that the problem of wall cracks can be solved to a certain extent, but the material has small elasticity and the repairing degree of the large crack is limited. In summary, the existing corresponding methods for solving the cracking problem of the insulation wall surface do not fundamentally eliminate the cracking problem, and the cracks can continuously grow and develop under the action of continuous internal stress or external stress.

The technical scheme adopted by the invention is as follows: a construction method for preventing a joint of a built-in heat-insulation shear wall and a filler wall under a window from cracking comprises the following steps:
step one, analyzing the specification and the size of a steel wire mesh frame plate of a filler wall under a window according to a construction drawing, and finishing the production of the steel wire mesh frame plate;
binding the shear wall reinforcing steel bars; after the shear wall steel bars are bound, installing the shear wall steel wire mesh frame insulation board and the under-window filler wall steel wire mesh frame insulation board at the end part of the shear wall;
anchoring the lower part of the heat insulation plate of the steel wire mesh frame of the infilled wall below the window at intervals of 20cm by using reinforcing steel bars not less than phi 6, wherein the anchoring length is not less than 30 cm;
fourthly, distributing through-length steel bars with the diameter not smaller than phi 8 at intervals of 20cm from the top on two sides of the steel wire mesh frame insulation board of the filler wall under the window, and anchoring the steel bars into the shear wall with the length not smaller than 25 cm;
step five, reinforcing the top of the steel wire mesh frame insulation board of the filler wall under the window by adopting a U-shaped steel bar with the diameter of phi 6;
and sixthly, sealing templates at two sides of the shear wall and the under-window infill wall, and integrally casting the shear wall and the under-window infill wall in situ by using concrete, so that the shear wall and the infill wall are integrated.
The invention has the following beneficial effects: the invention adopts the construction method for preventing the joint of the built-in heat-insulation shear wall and the window lower filler wall from cracking, solves the problem that the traditional built-in heat-insulation shear wall and the built-in heat-insulation window lower filler wall are easy to crack during construction, and carries out root cause construction mode adjustment from the crack generation position, so that the shear wall has good durability, low maintenance cost and deep social benefit.
