In the home improvement project, the operation of closing the balconies is generally required, and in particular, the bottom floor of the building should be treated. Blocking the balcony can play the following role.
The first is security: After the closure of the balcony, the house has an additional layer of protection. When the social security does not reach the level of night or night, there is a layer of protection. This creates an obstacle for criminals and can play a preventive role.
The second is health: After the balcony is closed, an additional layer of dust-blocking windows is used to help block sand, dust, and rain. The indoor sanitation is better than that of uncovered rooms.
The third is to expand the scope of use: In the case of relatively tense living conditions, the closed balcony can be used as a space for writing, reading, storing items, and exercising, and also as a living space. Compared to unsealed balconies, the forms of use are more diverse, increasing the area of ​​use of the living room.
The fourth is to broaden the design ideas: after the balcony is closed, the same room space can be connected as a whole by removing the door and connecting the window, which is conducive to overall consideration in the design, especially in the design of irregular rooms, should take the form of a closed balcony The overall design of irregular spaces.
1, the form of the closed balcony
There are two types of balconies in terms of their structure. One type is the anti-theft net cover seal. This method can only achieve the effect of security and theft, and other functions can not be played. It can be used in the case of loose living conditions. The other type is blocked in the form of windows. This form is most commonly used. From the appearance of the enclosed balcony, there are two kinds of flat seals and convex seals. After the plane is sealed, it becomes a plane with the exterior facade of the building, which is a relatively common outline of the closed balcony. After the convex balcony is closed, the window protrudes from the wall and there is a wider window sill, which is more convenient to use, but the construction is more complicated.
2, the material of the balcony
The general balcony can use plastic steel windows, aluminum alloy windows, solid window, fasting steel window, their difference is: plastic steel window has good weather resistance, heat insulation, sound insulation effect is better, but the price is more expensive, the color is relatively simple. The aluminum alloy window has better weatherability and anti-aging ability, but the heat insulation is not as good as other materials. The color is only white or tea, and the price is slightly lower than that of plastic steel. Solid wood windows can produce a rich shape, use a variety of colors, decorative effect is better, but the poor resistance to aging of wood, hot and cold expansion changes, after the sun and rain easily corroded, the price depends on the material, generally Pine wood is cheaper. Fast steel windows are sturdy and durable, but their production and processing are difficult, non-standard production cycle is long, at the same time the weight is heavy, and installation is also more demanding than other materials. A few days ago, the general family used a plastic window and an aluminum alloy window to seal the balcony.
3, construction specifications of flat sealing balcony
Regardless of the use of plastic steel windows or aluminum alloy windows, the dimensions of the enclosed surfaces of the balconies should be accurately measured before the sealing of the balconies. The window frames and fans should be sized and processed outside the construction site to reach the construction site. Before installation, check whether the size of the window is the same as the size of the opening of the balcony. Before the installation, the base layer of the balcony opening shall be cleaned, and the base material of the window shall be removed from the wall, and holes shall be drilled at the fixing points to predefine the expansion bolts or plastic expansion pins so as to fix the form. When installing a window, first hold the window in the hole and fix it with a wooden mold. Put the fixed steel sheet on the window over the expansion bolt. Fasten it with a nut. After all the steel sheets are installed, use The cement mortar grinds holes on both sides of the hole and embeds the fixed steel sheet in the cement mortar. After the cement mortar is hardened, the surface layer can be decorated. Note that the slurry on the window frame must be wiped off in time to prevent contamination of the window frame.
4, construction specifications of the convex seal balcony
Convex seal balconies should be made on the window sill, drill through holes in the balcony wall, insert steel bars, and the length of reinforcing bars is the same as the width of the window sill. Then, horizontal reinforcing steel bars shall be bundled on the front bars, and the distance between the bars of the connecting walls shall be 300 mm. The spacing of the horizontal bars shall be determined according to the width of the window sill, which is generally 200 mm, and two bars shall be used. Place the reinforcement underneath the reinforcement 30 mm away, nail the panel, cast the concrete mortar, and embed the wooden bricks or expansion bolts in the concrete. After the concrete hardens, remove the box board and clean the sill table top. If the top of the balcony is made of reinforced concrete, the method of construction is the same as that of the sill, but the vertical steel bars cannot be seen through and can be inserted into the top 100 mm of the balcony. Convex seals are installed on the balcony windows with a flat balcony.
5, acceptance of the balcony
After the balcony is fixed on the window frame, the window sash is installed. Generally, the balcony is used to push and pull the window. The requirement is close tightness, the gap is even, the splicing between the fan and the frame is tight, the pushing and pulling is flexible, the accessories are complete, the position is installed correctly, firm, flexible and applicable, and the appearance is correct.
