In the construction industry, the application of anchoring materials is extensive. Chemical anchors are a set of screws, nuts, gaskets, and hoses. They are made of high-quality carbon steel or stainless steel with medicaments and are suitable for non-cracked concrete. There is a special type of anchor bolt in the bolt, which is the chemical anchor bolt, and why is the anchor bolt special?
The following high quality fasteners wholesaler will explain to you what is a fixed anchor?
Shaped anchor bolts are anchor bolts that are determined on the type. They are determined from the diameter of the screw, the effective depth of the anchor, and the adhesive. It is used to withstand fairly high loads on cracked concrete and can be used to withstand shock and seismic loads.
Chemical Anchor Bolts
With the advancement of science and technology, the establishment of shaped anchor bolts has made building construction safer and more reliable. So far wedge anchor bolts have been used in curtain walls, steel structures, subways, tunnels, etc., and there are also characteristics of shaped anchor bolts differences.
1. Shaped high-strength chemical anchor bolts suitable for cracked concrete substrates;
2. The main component of the chemical tube is modified epoxy resin, real A-level anchoring agent, high and low temperature resistance, anti-aging for 50 years;
3. Injection-type planting, without the risk of uneven mixing of tubular medicament;
4. Anchor can be effectively anchored in wet and unclear water holes.
In different construction occasions, we need to use corresponding products. If non-conforming products are used, not only will the chemical anchor bolts not be able to bear the load, damage will occur, but also the stability of the curtain wall and steel structure will be affected. Choosing the right product is the most important.
Stainless steel expansion screws are generally referred to as metal expansion screws. The expansion screw is fixed by using a wedge-shaped slope to promote expansion to produce frictional grip and achieve a fixed effect.
The expansion screw is composed of a screw and an expansion tube, and the tail of the screw is conical, and the inner diameter of the cone is larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outward, and the conical part is moved by the axial movement of the thread, and then a large positive pressure is formed on the outer peripheral surface of the expansion tube, and the angle of the cone is small, so that the wall Friction and self-locking are formed between the cones, thereby achieving a fixing effect.
The spring washer on the expansion screw is a standard part. Because its opening is staggered and has elasticity, it is called a spring washer. The role of the spring washer is to use the sharp sharp corners of the wrong mouth to pierce the nut and flat washer to prevent the nut from loosening. The flat washer is also a standard part, its function is to evenly distribute the pressure of the nut on the connected parts.
Scope of application: Expansion screws are flat due to small drilling holes, large tensile forces, and exposed after use. If they are not used, they can be removed at will, and the advantages of keeping the wall flat are obvious. They are widely used in various decoration occasions.
☆ Fasten air conditioners, water heaters, range hoods, etc.
☆ Fixed frameless balcony windows, security doors and windows, kitchen, bathroom components, etc.
☆ Fixed by ceiling screw (used in combination with casing and cone cap)
☆ Other occasions that require fixing
Scope of application:
Entered the domestic market in 2013. It is widely applicable to concrete-embedded operations. Such as: architectural curtain wall, interior decoration, air conditioning, lighting, advertising sign, TV wall hanging, sanitary (kitchenware) water and electricity, monitor and other related industries and fields.
Testing method (universal material testing machine): Take 3 ~ 5PCS for concrete block construction test before production, and pull test through universal material machine. The test results can be in batch production after the tensile data meet the formulated tensile data After production, 5 to 10 PCS must be taken. After the relevant third-party inspection agency has obtained the relevant inspection data, the relevant inspection data is obtained. The average data of the two or more.
