Does perforation in the exterior wall destroy the insulation, and does perforation in the high rise

If the exterior wall is not drilled in a standardized manner, the insulation layer will be damaged, but as long as the hole is punched in the wall according to the spacing required by the specification, and the special insulation nail is finally installed, the insulation layer will not be damaged under normal circumstances. Although the installation of insulation nails requires the use of electric drills.

The hole is made on the wall, but the size of the insulation nail hole is very small, about 8mm, so it will hardly have any impact on the wall. In addition, the depth of the hole will not damage the wall, and the use of an electric drill to open a hole in the wall will not damage the steel bar. Because we use an electric drill to open holes, if we encounter steel bars, we can't hit them, so the holes in the wall when installing the insulation board can't hit the steel bars, that is to say, it will not cause damage to the steel bars.

As long as the code requires the punching, there will be no major problems.

The reason why the insulation layer is not allowed to be perforated is to ensure the thermal insulation performance and structural safety of the building. Insulation is a material used to enhance the thermal insulation performance of a building, and it is usually located on the exterior wall or inside the roof of a building. Punching can compromise the integrity of the insulation, leading to the permeability of heat and moisture, which in turn can affect the insulation of the building.

First of all, the main function of the insulation layer is to reduce heat transfer. When a hole is punched, a thermal bridge is formed, allowing heat to be quickly conducted through the hole to the inside or outside of the building, causing the insulation to lose its ability to act as an insulator. This will lead to increased energy consumption in buildings, higher heating costs in winter, higher cooling costs in summer, and potentially unstable indoor temperatures.

Secondly, perforation can also cause moisture to build up inside the insulation. Insulation usually has some waterproof properties, but if there is a hole in the case, moisture will easily enter the inside of the insulation and accumulate. Long-term accumulation of moisture can lead to rot and mildew of insulation materials, affecting their thermal insulation performance and service life, and may also cause damage to the structure of the building.

In addition, perforation poses a potential threat to the structural safety of the building. To a certain extent, the insulation layer bears a part of the load, such as wind pressure, seismic resistance, etc. If holes are drilled in the insulation layer, it will have an unpredictable impact on its mechanical properties, which may reduce the overall structural strength and stability of the building, and even increase the risk of disasters.

In short, the insulation layer is not allowed to be perforated in order to ensure the thermal insulation performance and structural safety of the building. During the design and construction process, it is necessary to strictly follow the relevant codes and standards, select insulation materials that meet the requirements, and take appropriate construction measures to ensure the integrity and function of the insulation layer.

Punching holes in high-rise facades can destroy the waterproofing layer.

The exterior wall is generally waterproof, and punching holes will destroy the waterproof layer, and rainwater will easily cause loose concrete, which will cause safety accidents.

The load-bearing wall of the high-rise exterior wall is the structural framework that mainly bears the weight, and the reason why the hole is not allowed is that the owner is afraid that the owner will destroy the original structure and destroy the stability of the building structure during the punching process. Because there are generally basic structures such as steel bars and wires in the load-bearing walls of high-rise exterior walls, if the basic structure is damaged too much, it will affect the damage resistance of the original house, and even cannot be repaired.

The main specifications for punching holes in exterior walls are as follows:

1. The main body of the building and the load-bearing structure shall not be changed without the design plan proposed by the original design unit or the design unit with the corresponding qualification level.

2. The original energy-saving facilities of the house can not be damaged, and the exterior wall can not be changed at will, and it is very dangerous if the pipeline buried in the wall is punched when punching.

3. Do not carry out other behaviors that affect the safety of the building structure and use.

Exterior wall insulation can be punched, but when punching, it is important to note that the size of the hole must be small. Generally, punching 8mm holes in the wall will hardly have any impact on the wall, and naturally it will not affect the insulation layer. In addition, the depth of the insulation nails that we commonly install the insulation board is generally the thickness of the insulation board plus about 30mm, which means that we need to punch a hole depth of 30mm on the stressed wall.

For our exterior walls, it is basically a two-four wall or a three-seven wall, so a 30mm Senkong will not damage the wall.

Precautions for exterior wall insulation construction 1, each sub-grid unit of exterior wall insulation must be completed at one time. It is forbidden to have a connection in a compartment. Secondly, when approaching the edge of the lattice strip, it should be finely processed.

Do not wipe the new plastering mortar to the adjacent plates, and avoid secondary polishing of the finished plates when grinding. The third horizontal lattice joint position is not less than the height of each step of the scaffold, and the fourth construction wall should take sunshade and windproof measures. Then, after the construction is completed, avoid rain washing for 24 hours.

2. At present, China's external wall insulation technology is developing rapidly, which is the focus of energy-saving work. Although the technology and construction quality of external insulation products still need to be improved, the promotion and implementation of external thermal insulation technology of building external walls is not only conducive to the sustainable development of the country, prolonging the service life of buildings, but also conducive to saving daily expenses for every household, which is the general trend. However, the external insulation of the external wall has relatively high requirements for product technology and construction quality, and puts forward higher requirements for the construction team.

Therefore, in order to improve the quality of anti-external wall insulation construction quality, it is necessary to strictly control the materials and construction.

3. The parts that are easy to be overlooked in the practice of external wall insulation are those linear overhang parts, such as balconies, rain covers, balcony railings against the exterior wall, shelves of air conditioning outdoor units, attached pilasters, bay windows, decorative lines, partition walls of external walls and balconies, eaves, the inside and outside of the parapet wall and the top pressing, gutters, and the doctor's hat with roof decoration modeling.

4. For those parts that have not been insulated, the deformation of the wall affected by temperature is different from that of the wall that has been insulated, the thermal expansion and contraction are inconsistent, and the plastering layer is easy to hollow. After several years of damage at the junction of the temperature difference, it will cause these uninsulated parts and the wall junction of the external thermal insulation to produce damage cracks, infrared test shows that these neglected parts are obvious thermal bridges, compared with the insulated parts, the temperature is affected by the environment is very obvious, and the resulting temperature difference stress is easy to cause cracks at the junction of the part and the main part. At the same time, the presence of these thermal bridges will also have a detrimental effect on the overall energy saving effect.

If you hit a small hole of 60-70, no matter where you hit it, it will not affect the quality of the house.

It is better not to hit on concrete.

It is not good to be directly above and below the window, so it is best to hit the window at a proper distance.

1. Cigarette terminology. Punch holes in cigarette or pine paper to increase the paper's air permeability and air dilution.

2. Book publishing terminology. It refers to the loose-leaf cards or various leaflets of this album, etc., according to a certain specification on the staple with eyelets that can be pierced (generally 3-5mm in diameter). The number of holes is generally 2, but it can also be more or less as needed.

3. Use an appliance with a drill bit to drill or drill holes in solid or solid materials.

4. perforation; Pierce to make a hole.

5. Fabric style processing technology terminology. Punch different patterns or holes distributed according to a certain pattern on the fabric, so as to show the different styles of the fabric.

6. In the field of communication, puncturing means to remove redundant bits.

After punching the hole, it is OK to do the waterproof treatment.
