Anchor Bolts Tensile Strength
Sep 29, 2017

Anchor bolt is a new type of metal fastening material composed of chemical agents and metal rods. Can be used in various curtain wall, marble dry-hanging construction of the installation of the post, also can be used in equipment installation, highway, bridge guardrail installation; Building reinforcement and renovation, etc. Because of its chemical glass tube filled with flammable and explosive, so manufacturers must be approved by the relevant state departments to production, the whole production process requires strict security measures, and use a completely isolated and staff of the assembly line production. If manual work is not only violated the relevant regulations of the state, it is also very dangerous. Chemical anchor bolt is a new type of following expansion anchor bolt, is through a special chemical adhesive, fix the screw cement concrete base material in drilling, in order to realize the fixed anchor composite parts.

The anchor bolt often works with the concrete base to carry the weight and load of the machine to ensure the smooth operation of the machine. The material of the anchor bolt used for concrete structure can be carbon steel, stainless steel or alloy steel, according to the difference of environmental conditions and the requirements of durability, the corresponding varieties should be selected. The performance of anchor bolts shall be in accordance with the relevant provisions of the standard of construction industry of the People's Republic of China.

In the use of concrete pedestal, weathering, severe crack, and uncompacting will lead to loose anchor bolts, which will cause the vibration of the machine to intensify and affect the normal operation of the machine parts. The traditional method of repairing will result in the increase of production downtime, resulting in huge economic losses. In order to solve the problem of bolt loosening, the more effective method of repair abroad is to adopt macromolecule composite material, while the most mature in China is the American jiahua concrete repair material. The anti-impact and compressive strength of the material itself is far greater than that of concrete and has the properties of various chemical media. Its superior tackiness to concrete strength of adhesion is greater than that of concrete itself (concrete would be broken) first, at the same time also adhesion to steel and other rough surface, and fast curing properties, can save the loss caused by production for the enterprise.

Use and scope of application

It is mainly used in high-end construction in foreign countries, such as Europe, the United States, Middle East, Japan, South Korea and other developed countries, and entered the domestic market in April 2013.

It is widely applicable to the planting of mixed soil. Such as: building curtain wall, interior decoration, air conditioning, lighting, advertisement kanban, TV wall hang, sanitary ware (kitchen utensils) hydropower, monitor and other related industries and fields.

Compared to the advantages of traditional expansion anchors

1. Extensive applicability. As long as the common thread size fits, it is suitable for any type of anchor head type.

2. Selection of construction method. The function and effect of the preset of the preset on demand, or the drilling (loading) of the single construction filling line is the same

3. High construction success rate. No hole depth is attached and the drilling inclination is disturbed, the construction achievement rate is 100%.

4. The design of the kaohsiao. The whole tooth taper expansion special inverted hook design.

5. Lock for anti-loosening effect. The whole tooth taper expansion special design, using the reverse thrust effect is urgent to lock the workpiece.

6. Perfect design thinking. Short and simple, suitable for the sale of all market screws, DIY and works the most desirable construction of the parts.

7. Guarantee anchor expansion. Metal plate press products, patent full - tooth taper expansion design, gripping ability not idle, no professional construction skills.

No problem left. Just pull out of the anchor work piece, apply the filling agent to restore the plane, no excision disturbance and protruding object to strike the danger.

Tensile strength

The tensile strength concrete 25N/mm2 is compared with the tensile strength of 800Kg and the hole diameter of 10.5mm is 40mm. Static vertical load of 800 hours/test the displacement of 500Kg is 1 mm.

The market product (M8) has a tensile strength of 600Kg, and the hole diameter of 10.5mm is 45mm. Static vertical load weight 800 hours/test the displacement of a 400 kg is 1 mm.

However, the product must control the depth of the hole or need special tools to use. The control is not good enough to affect the tensile strength and even cause the product to fall out. And the new internal screw length controls the expansion condition of the mother parts, but the full expansion will not cause the mother parts to fall out.

Detection method (universal material testing machine) : take 3 ~ 5 PCS before production test for concrete block construction, in through the universal material machine drawing test, test results must be in accordance with set after the tensile data of batch production, can be performed after mass production needs to apply object 5 ~ 10 PCS in the committee by a third party inspection agencies inspection after get related testing data, make a related testing data, both the above average.
