What are the domestic chemical anchors? How much is a set of domestic chemical anchors urgently

The grade indicates the material of the screw. Such as level, level. For example, the inverted conical shaped chemical anchor bolt of Nanjing Mancartel, the tensile force of grade M12 is 68 kN, but the average brand is only 20 kN!

Because the special MT500 planting reinforcement glue equipped by Nanjing Mancartel is a grade A glue, the screw of the glue pulling M30 is screw yielding. It has passed the fire protection certification, underwater application certification, anti-aging 50 years certification, and safety appraisal certification! It has been widely used in key projects including Shanghai Disneyland and Harbin Metro!

Among the mechanical anchor bolt manufacturers, it is also better to belong to Nanjing Mancart. Contact Mancartel 4oo 894 5118 Nanjing Mancatel's mechanical anchors have passed the seismic resistance, fatigue resistance certification and fire protection certification. Take 12 as an example, the rally reaches more than 60 thousand N!

It has been widely used in Nanjing Metro, Shenzhen Metro, Marriott Hotel, etc

In the case of domestic chemical anchors, many manufacturers are not in place in size, and there are problems with the material, so that it is naturally cheaper, and sometimes only a few cents for M12 specifications. So in this society now, the brand value is there, after all, it can allow us to avoid detours and buy with confidence. About the domestic chemical anchors I know mainly include Shanghai Dali Chemical Anchors, Xugong Chemical Anchors, and Stetech Chemical Anchors, and detailed information can be consulted by the company.

Shanghai Shibang is good, I often use theirs.

4 yuan per set. Chemical anchor bolt is a high-strength anchor bolt with vinyl resin as the main raw material, which was called chemical bolt in the early days. Chemical anchor bolt is a new type of anchor bolt that appears after the expansion anchor, which is a composite part that is cemented and fixed in the concrete substrate borehole through a special chemical adhesive to realize the anchorage of the fixing.

Characteristic. Because the chemical reagents contained in the glass tube are flammable and explosive, the manufacturer must be approved by the relevant state departments before production, and the entire production process needs to have strict safety measures, and must use an assembly line completely isolated from the staff. If it is done manually, it not only violates the relevant regulations of the state, but also is very dangerous.

The domestic Shanghai Shibang I use is not bad, only a few dollars a set, and the quality is very good.

There are three types of chemical anchors, namely high-strength chemical anchors, inverted conical anchors and shaped anchors. Although there is no relevant specification to limit their specifications and models, the industry has basically determined the distinction between national standards and non-standards. The national standard models of the three chemical anchors are basically the same, and their specifications and models are as follows:

What are the specifications and models of chemical anchors? The vast majority of these manufacturers do not produce M8 inverted conical anchors and shaped anchors, of course, the amount of chemical anchors in M8 specifications is very small. Customization of non-standard chemical anchor bolts 1) Increase the length of screw leakage This scheme is caused by the thickness of the anchorage, and such a scheme is recognized when the pure basic performance of the anchor bolt itself is satisfied.

The elongated chemical anchor needs to be specially customized, and the processing cycle is much longer than the conventional model, and the quantity is moderate (more than 10,000) in order to be better, such as pants Zen and chemical anchor manufacturers to talk about ** and follow-up services. What are the specifications and models of chemical anchors? 2) Increase the buried depth to the level M12 chemical anchor bolt as an example, the national standard buried depth is 110mm, and the pull-out test result on C30 concrete is the anchor bolt breakage, then it shows that the buried depth of 110mm can fully play the ultimate mechanical properties of the anchor bolt material (35 steel), and the buried depth has no practical significance, and even increases the difficulty of construction.

Designer's misunderstanding: do not understand the limit of the bearing capacity of the anchor bolt, blindly increasing the length of the anchor bolt will only bring greater difficulty to the construction, but also increase the cost of the project. Taking the M24 chemical anchor bolt as an example, the national standard burial depth is 210mm, and the pull-out test result of the chemical hose construction on C30 concrete is the failure of the concrete rubber surface.

However, if the original mechanical properties can already meet the needs of the project, the increased mechanical properties are not very useful, and it is difficult to find manufacturers on the market who are willing to make long-sized chemical tubes, so it is difficult to carry out the project. Therefore, we can only take another solution, which is to cooperate with the construction of injection planting reinforcement glue, and the standard buried depth can break the screw after the colloid is fully functional, which is the simplest improvement method. To put it simply, there is no need to increase the burial depth of small-sized (M16 and below) chemical anchors, and forcibly increasing them will only increase the cost and workload.

At present, the brands in the domestic market are relatively good, with Shanghai Shibang brand, complete test reports and good quality.

Chemical anchor bolt is a new type of fastening material, which is composed of chemical agents and metal rod body. It can be used for the installation of embedded parts in the construction of various curtain walls and marble dry hanging, and can also be used for equipment installation, highway and bridge guardrail installation; Building reinforcement and renovation and other occasions. Because the chemical reagents contained in the glass tube are flammable and explosive, the manufacturer must be approved by the relevant state departments before production, and the entire production process needs to have strict safety measures, and use an assembly line that is completely isolated from the staff.

Through a special chemical adhesive, the screw is cemented and fixed in the concrete substrate drilled hole to realize the composite part of the anchorage of the fixing.

Beijing Liwang anchor bolt has a full range of products, excellent quality and comprehensive customization.

I know the brand of Shanghai Shibang for more than ten years, and we often use it for curtain walls!

Anchor: is a common name for the application of post-anchoring technology, corresponding to the embedded technology, which originated in Germany. Because there are certain defects in the embedded technology, in practical application, large buildings are prone to displacement and size errors in the construction process due to the pre-designed buried position, resulting in the inability to correspond during the subsequent installation, and because of such confusion, the post-anchoring technology is born.

Mainly used in the construction industry, its role is to fix the load on the main structure, so that it can withstand the effects of external conditions, including dealing with natural disasters. At the heart of the post-anchoring technology is safety and reliability! Without safety and security, everything else is empty talk.

Anchors are generally divided into two categories: one is bonded row anchors (chemical anchors), and the other is metal anchors. The main defect of the chemical anchor is the problem of aging and temperature resistance, because the adhesive is organic chemicals, so there must be aging; The advantage is that there is no displacement.

Metal anchor bolt is the mainstream trend in the future, metal anchor bolt is divided into two categories, one is friction type, its defect is that displacement will occur under certain conditions, and the current friction anchor bolt is in the process of elimination. The second type is the cutting and expansion type, which is divided into self-cutting type and bottom expansion type, which has the advantages of safety and reliability, moderate, easy to use, can better solve the problem of displacement, and there is no aging problem, and it is the best anchoring product with the best safety at present.

The main brands in the anchor bolt industry are: foreign fischer and hilti, and domestic brands such as Pengkun, Stei, Sailfish, and Ruitai.

Personally, I think: Pengkun's metal anchor bolt is the best safety and reliability, its unique two-way self-cutting + bottom-expanding technology patent, has been sued by the industry boss fischer company, fischer company with deep pockets, want to bully this Chinese private enterprise, as a result, Pengkun company resolutely responded to the lawsuit, to demonstrate the original two-way self-cutting principle to the court, fischer company quickly withdrew the lawsuit.

The above comments are for your reference, and I hope they can reach you.

Strong anchorage, similar to pre-embedding.

No expansion stress and small margin spacing.

The installation is fast, the solidification is fast, and the construction time is saved.

Glass tube packaging facilitates visual inspection of tube quality.

After the glass tube is crushed, it acts as a fine aggregate and is well bonded.

Mechanical anchor bolt and chemical anchor bolt are a kind of material to strengthen the fastening of the object, in practical use, you can choose according to your own needs and environmental requirements, because of its different material principles, so there are differences, the following is a comparison of their differences:

1.Earthquake resistance.

The seismic resistance of chemical anchors is basically below level 7, while the seismic resistance of mechanical anchors can reach level 8.

2.High temperature resistance and weldability.

The chemical anchor has a lower relative melting point and a weaker high temperature resistance than the mechanical anchor.

3.Reliability.

The metal material used in the mechanical anchor bolt is better, which is conducive to the long-term maintenance of the fastening force, while the chemical anchor bolt can not fully play its role because of the level of the construction personnel and the incomplete hole cleaning work, thereby reducing the durability of the fastening force.

4.Construction.

Chemical anchors are chemically cured and take a curing time, while mechanical anchors are ready to install and do not have to wait.
