Do I need to nail the insulation board? What is the length of the nail insulation nail for the exter

Yes, it is for anchoring, not nailing! Flat roofs are generally not required to nail insulation nails on the roof of the roof.

1. The pasting of the insulation board usually uses a binder (adhesive mortar or dry mortar) in the current construction.

etc.) will be insulated board with the base treatment (masonry structure.

Generally, the base plastering treatment is used, and the surface of the concrete structure is generally coated with interface agent.

The external or internal walls of the building are bonded together, and the bonding rate of the adhesive mortar is generally -10 floors for six-storey buildings not more than -18 floors and not less than 50%.

2. Most of them use benzene board and EPS polystyrene board.

As exterior wall insulation materials, and if these materials are exposed to the air, they are easy to weather, so they are required to be treated on their surfaces in time to isolate the insulation board from the air.

3. In order to make the insulation board and the base layer reliably connected, anchor bolts are usually used on the insulation board.

The method of reinforcement increases the connection between the insulation board and the base layer, the head of the outer end of the anchor bolt is larger, and its root is anchored into the structural entity of the building, and the contact area between the big head and the insulation board is several times larger than that of the iron nail, so that the area of the insulation board is pressed is wider, and the benzene board is not easy to slide out from the anchor bolt head, and the bonding effect of the insulation board and the wall body has been achieved; If the surface layer of the insulation board is treated properly, the service life of the wall insulation can be extended!

Insulation nails need to be used to paste insulation boards.

Insulation nails are mainly used for fixing the insulation board in the external wall insulation system, which has the characteristics of anti-aging, anti-temperature abrupt change, anti-corrosion, cold and heat resistance, high bearing capacity, high pressure-bearing, good tensile performance, not easy to deform after loading, moisture-proof, shock absorption, noise absorption and good insulation, and easy to install. The number of insulation nails installed is related to the height of the building.

The number of insulation nails installed per square meter should meet the following requirements: 4 below the building height of 20m, 5 when the building height is 20 50m, 9 when the building height is 50 90m, and 11 when the building height is more than 90m. In particular, the number of insulation nails should be increased on both sides of the gable and the large corner of the gable in the passage between buildings where the spacing between buildings is too small to a few meters wide.

This one has to do with the thickness of your insulation. Generally, it should be at least 4 cm into the wall concrete, which is the effective depth.

That is, you insulation 10 + 1 mortar + 4

The length of the external wall insulation nail = the depth of the insulation nailed into the wall (greater than 25mm) + the thickness of the fixed layer of the rock wool board (generally about 5mm) + the thickness of the rock wool board + the thickness of the protective layer (3 5mm, or 8 15mm).

The depth of most insulation nails into the wall represents the distance to the load-bearing wall, and the general distance is about 5cm, and the depth of the wall that needs to be set in different cities is different.

Yes, it is for anchoring, not nailing! Flat roofs are generally not required to nail insulation nails on the roof of the roof.

1. The pasting of the insulation board, in the construction of the remaining Songxing, the adhesive (adhesive mortar or dry mortar, etc.) is usually used to bind the insulation board with the outer wall or interior wall of the building that has been treated with the base layer (the masonry structure is generally plastered with the base layer, and the surface of the concrete structure is generally coated with interface agent), and the bonding rate of the bonding mortar is generally -10 floors not greater than -18 floors not less than 50%.

2. Most of them use benzene board and EPS polystyrene board as external wall insulation materials, and if these materials are exposed to air, they are easy to weather, so they are required to be treated as a surface layer on their surface in time to isolate the insulation board from the air.

3. In order to make the insulation board and the base layer reliably connected, the method of anchor bolt reinforcement is usually adopted on the insulation board, the vertical hall Zheng connection between the insulation board and the base layer is increased, the head of the outer end of the anchor bolt is larger, its root is anchored into the building structure entity, the contact area between the big head and the insulation board is several times larger than the iron nail, the area of the insulation board is wider in this way, and the benzene board is easy to slide out from the anchor bolt head without ambush, and the bonding effect of the insulation board and the wall has been achieved; If the surface layer of the insulation board is treated properly, the service life of the wall insulation can be extended!

Thermal insulation anchor nail state sock blind is a new type of fastener used for the fastening of interior and exterior wall insulation materials, which can replace the expansion anchor bolt for thermal insulation construction. In order to ensure the use of the product, please contact customer service before purchasing, and our intimate technical service. According to the thickness of your insulation board, if the thickness of the insulation board is 3cm thick, choose 3cm long insulation nails, and so on.

If the wall is an empty block of the gas book, the length of the steel nail should be selected.

Hello For the construction of exterior wall insulation boards, whether nails can be used, here are the following instructions:1The insulation board is a heat-resistant insulation material, and its thermal expansion rate is usually large.

When using nails to fix the insulation board, it is necessary to consider the expansion and deformation of the insulation board at the service temperature to avoid tearing the board surface or loosening the nails. Therefore, the selected nail material needs to have a high expansion coefficient to match the thermal expansion characteristics of the insulation board, and use appropriate spacing to ensure that the insulation board can be effectively stretched. This is the key point of using nails to install insulation boards.

2.The thickness of the insulation board is large, generally ranging from 50-200mm. The nails used must be able to penetrate the insulation board completely to prevent the formation of voids with thermal expansion, which can affect the locking and insulation performance.

At the same time, it is not advisable to shoot nails that are too long, so as not to damage the wall structure. Therefore, choosing the right size range for the nails is the key to completion. 3.

The mounting surface of the insulation board is usually large, and the use of a large number of nails can ensure a secure lock, but it can also affect the sturdiness and aesthetics of the wall. Therefore, while ensuring safety, it is also necessary to control the number of nails, and appropriately select auxiliary tools such as glue and special clips to match or replace part of the nails to achieve efficient and concise fixing. 4.

When adding the installation tools recommended or required by the manufacturer to the insulation board, the use of nails should also be adjusted in combination with the overall scheme to avoid conflicts. Prefer professional, safe, and concise installation methods and tools. To sum up, it is feasible to fix the external wall insulation board with stove cleaning nails, but it is necessary to pay attention to the thermal expansion characteristics of the insulation board, the selection of nail material and size, the control of installation density, and the construction specification is made in combination with the specific installation method of the insulation board.

Only by taking into account the thermal insulation effect and the safety of the wall structure, it is appropriate to choose the appropriate tool configuration and use nails to fix the insulation board. Flexibility is also key. If you have any other questions, please feel free to continue to consult.

Insulation nail is a component used to fix insulation materials, usually used to strengthen the bond strength of the insulation board and the base of the building in some cases.

Specifically, according to the provisions of the "Technical Specification for External Thermal Insulation of External Walls" JGJ144-2019, for extruded polystyrene (XPS) insulation board and polystyrene (EPS) insulation board, when the surface of the base is fixed by the point frame adhesive method or strip adhesive method, anchors or insulation nails and other components should be used together to enhance the bonding strength of the insulation board and the building base. At the same time, it is also necessary to pay attention to the length of the insulation nail to ensure that it can be firmly passed through the insulation board and is well fixed inside the base layer.

Therefore, it can be said that the use of insulation nails helps to improve the bonding strength of the insulation board and stabilize the hall, but the premise of its effectiveness is that the surface of the base layer must be smooth, clean, free of various dirt and dust such as oil and dust, so as to obtain the best construction effect.

"Technical Regulations for the Construction of External Thermal Insulation of External Walls" (Practices for External Wall Polymer Cement Polystyrene Insulation Board) for the record of the letter construction standard Bei Yi No. 88.

Exterior wall insulation nails should be driven 5 cm into the wall. In general construction, anchor bolts are set up at the corners of the insulation board and the seam of the board, and the spacing is not more than 600, and the number is 4-6 square meters.

The depth of most insulation nails into the wall represents the distance directly to the load-bearing wall, and the distance of the general jujube is about 5cm, and the depth of the wall that needs to be set in different cities is not the same. If ceramsite hollow bricks are used as the main building material of the wall, then the use of noisy dismantling insulation nails should be knotted insulation nails.

Precautions for exterior wall insulation boards.

Due to the high strength, large shrinkage and insufficient flexibility and deformation of traditional cement mortar, if it directly acts on the outside of the insulation layer, it not only has poor weather resistance and is easy to cause cracking, but also may fall off, which has huge potential safety hazards. Therefore, it is necessary to use a special anti-crack mortar supplemented by a reasonable reinforcing net, and add an appropriate amount of fiber to the mortar.

The compression-fold ratio of anti-cracking mortar is less than 3If the exterior finish is a face brick, steel wire mesh can also be added to the anti-crack mortar. The hole spacing of the steel wire mesh should not be too small.

It should not be too big. The short side of the face brick should be covered with at least two or more mesh holes, and the steel wire mesh should be made of hot-dip galvanized steel wire mesh with good corrosion.

Hello dear, happy to answer your <>

Answer: The insulation board can be vertically pasted instead of vertically paved, and should be paved horizontally and horizontally. The pasting of the insulation board should start from the edges of doors and windows and the corners of the walls, and gradually move towards the middle.

Paving in a section should be carried out from the bottom up. The insulation board should be paved with a long horizontal paste to ensure continuous combination, and the upper and lower two rows of insulation boards should be staggered and glued vertically, and the staggered seam is generally 1 2 board length, and the minimum staggered seam of some parts shall not be less than 200mm.
