What are the advantages of back bolt dry hanging stone curtain wall

Advantages: 1. Compared with the traditional wet operation process, the process eliminates the grouting process, shortens the construction period, reduces the weight of the building, and improves the seismic performance. More importantly, it can effectively prevent the infiltration and pollution of saline-alkali pigments on the stone during the grouting process, and improve the decorative quality and aesthetic effect.

2. The traditional decorative board with grouting as the means of connection may fall off from the decorative board due to the expansion and contraction deformation of the decorative board caused by the seasonal outdoor temperature difference, which poses a threat to personal safety. In contrast, the construction technology of dry-hanging stone can effectively prevent the occurrence of decorative board falling off accidents.

3. This kind of back-bolt dry-hanging stone curtain wall installation process can also be used with the installation process of glass curtain wall or large glass window and metal decorative plate. At present, many large public buildings in China have adopted the construction technology of dry-hanging stone in the installation of stone interior and exterior decorative panels.

During the construction process, the suspension position on the back of the plate can be freely selected, and the hanging can be assembled at any angle, which provides space for the design requirements of different specifications, different shapes and various complex shapes. Due to its high installation precision, good decoration effect, simple structure, flexible practice, convenient disassembly and assembly, it has created convenience for maintenance and maintenance, and overcame the disadvantages of cement mortar binder penetrating into the stone when wet pasting and the defects such as easy damage, easy rust and no safety guarantee for the stone in the operation of the traditional pin pin and pin plate dry hanging method.

According to reports, the principle and characteristics of the back bolt stone curtain wall The back bolt stone curtain wall is connected with the keel by the back bolt and the pendant, and the bolt and the stone are fixed without expansion force through the bottom hole extension technology, which is reliable, reduces the stress concentration phenomenon formed due to the opening, and at the same time weakens the slate is smaller, which reduces the possibility of local damage to the stone at the connection site, and can also reduce the loss rate of the stone dry-hanging stone curtain wall tool Jinlida electric hanging basket.

For the large surface stone, each stone has four back bolt pendants, each pendant bears the weight of the stone evenly and the contact area between the stone pendant and the keel pendant is large, and the corresponding strength and stability are good, so that the stone panel has high seismic resistance. Therefore, it can be applied to high-rise and super-high-rise façade finishes.

Nowadays, many medium and high-end curtain wall building exterior walls are basically made of stone or glass during construction, and the back-bolt stone curtain wall dry hanging method is a more commonly used structure at present. So, what is the dry hanging method of back-bolt stone curtain wall? What are the advantages of the dry hanging method of back-bolt stone curtain wall?

Let's take you to find out.

What is the dry hanging method of the back-bolt type stone slag curtain wall.

The backbolt stone curtain wall dry filial piety hanging method refers to the dry hanging of the stone through the back bolt and the pendant, and the specific use of which pendant needs to be selected according to the keel welding. However, each stone must be supported by four back bolts, which are safer than the slotted hanging method, which is safer than the slotted hanging method.

Advantages of the dry hanging method of back-bolt stone curtain wall.

1. Compared with the traditional wet operation, the dry hanging method of the backbolt stone curtain wall is carried in addition to the grouting process, which effectively shortens the construction period and reduces the weight of the building, so as to effectively improve its seismic performance. In addition, the most important thing is that this process can effectively prevent the penetration and pollution of saline-alkali pigments on the stone during the grouting process, and can improve the decorative quality and aesthetic effect.

2. The traditional process is to use grouting as the main point of connection, but it will cause the phenomenon of expansion and contraction deformation of the decorative board due to the seasonal outdoor temperature difference, and may even fall off, which poses a threat to our personal safety. Compared with the first, the construction process of dry-hanging stone can effectively prevent the occurrence of falling off accidents.

3. The installation process of back-bolt dry-hung stone curtain wall can be used together with the installation process of glass curtain wall and metal decorative plate, and many large-scale public buildings in China are basically using dry-hanging stone technology.

Article summary: The above is all about what is the dry hanging method of back-bolted stone curtain wall and what are the advantages of the dry-hanging method of back-bolted stone curtain wall, I hope it will be helpful to you. If you want to know more about it, please stay tuned to Qeeka Home.

It is composed of stone panels and supporting structures (beams, columns, steel structures, connectors, etc.) and does not bear the load and function of the main structure of the building shell.

Stone curtain wall has been on the rise in China, the amount of pendants has also increased, now the industry is most concerned about the quality of the pendant, although the pendant is only a small accessory in the entire stone curtain wall, but it plays a role in pulling out thousands of pounds, it can also be said that the pendant is one of the most critical accessories in the quality and safety of the entire stone curtain wall.

The fire performance of the back-bolt stone curtain wall is very poor, especially in high-rise buildings, the fire is generally ignited indoors, the fire in the building will increase the temperature of the stainless steel plate and the metal structure of the hanging slate, so that the steel will be softened, lose its strength, and the slate will form a slate "rain" from the high-rise to fall, which not only causes danger to pedestrians, but also causes difficulties to fire fighting.

The dry hanging of the backbolt stone curtain wall refers to the professional opening equipment, the back of the porcelain plate is accurately processed inside the large and small outside of the conical round hole, the anchor bolt is implanted into the hole, screwed into the screw, so that the bottom of the anchor bolt is complete, and the conical hole coincides, forming a stress-free convex combination, and the stone is fixed on the keel through the connector.

The dry hanging of the backbolt stone curtain wall is mainly to lock the stone by using the unique internal wedge cut of the back bolt to open the simple collapse, and each stone must be supported by four back bolts.

Each pendant bears the weight of the stone evenly, and the stone pendant and the keel pendant are touched but the volume is large, and the insects that are quietly round are busy, so that the stone panel has a high seismic resistance. Therefore, it can be applied to high-rise and super-high-rise façade finishes. However, it is necessary to install a steel keel, and the insulation should be installed separately.

The specific construction process of stone dry hanging is as follows:

1. The dry hanging of stone needs to be constructed in strict accordance with the drawing, and during the construction of the steel frame, the in-place hole of the ceiling plate can be appropriately opened, so that the plate can be fine-tuned when it is in place.

2. Review the size of the hole in place, and loft out to determine the position of the hole on the back of the plate and the position of the pin hole on the side.

3. Two holes with a diameter of 6mm and a depth of 30mm are drilled on the side of the material.

4. The drilling diameter on the back of the plate is 10mm, and the positioning pin is used to ensure the drilling depth of 40mm, and each plate is drilled 4 holes.

5. Clean the dust in the borehole and inject an appropriate amount of AB glue into the hole; Cut the length of the expansion pipe into 4cm (this work can be done in advance), then find the expansion bolt, and use the casing to drive the expansion pipe into the borehole until it is flush with the slate; Then use flat pads, stone curing spring gaskets, and nuts to fasten.

6. The hanging board is in place, the first board is installed, and the hanging wire and supporting plate are adjusted and fixed; Then install the side fastener and pin pin; Then install the second plate, align the side hole pin and bolt fixing hole, adjust it in place and tighten it with a flat gasket, spring gasket and nut. The rest of the board material is installed in this way.

7. After the installation of the stone dry-hung ceiling board, it is cleaned and glued.
