The applicable range of expansion screws, the following small expansion anchor bolt manufacturers Xiaobian for everyone to introduce:

At present, it is mainly used in foreign high-end construction fields, such as Europe, the United States, the Middle East, Japan and South Korea, and other developed countries, entering the domestic market in 2013. It is widely used in the operation of embedding concrete. Such as: building curtain wall, interior decoration, air conditioning, lighting, advertising billboards, TV wall hangings, bathroom (kitchenware), hydropower, monitors and other related industries and fields.

Advantage

1. Wide applicability. As long as the male thread size is the same, it is suitable for any type of anchor head. 2. Construction method selection. The point preset can be selected according to the requirements, or the drilling can be installed (loaded) in a single construction, and its function and effect are completely consistent. 3. High construction success rate. There is no hole depth attachment and drilling inclination, and the construction achievement rate is 100%. 4. High-grade design. Full-tooth taper expansion special inverted hook design. 5. Lock the anti-loose effect. The full-tooth taper expansion is specially designed to lock the workpiece tightly with the reverse thrust effect. 6. Improve design thinking. Short and simple, it is suitable for all the commercially available screws, DIY and the most desirable construction options for the fortifications. 7. Ensure that the anchor bolts expand. Metal plate pressing products, patented full-tooth taper expansion design, strong gripping ability, no need for professional construction skills. 8. Disposal without trouble. As soon as the anchor part is withdrawn, the filling agent is applied to restore the plane, without the trouble of resection and the danger of the impact of the protrusion.

tensile strength

The tensile strength concrete 25N/mm2 is compared with the tensile strength ≧800kg, the hole diameter is 10.5mm, and the drilling depth is 40mm. Static vertical load 800 hours / test ≦ 500kg displacement ≦ 1 mm. Commercially available product (M8) has a tensile strength of kg600kg, a hole diameter of 10.5mm, and a drilling depth of 45mm. Static vertical load 800 hours / test ≦ 400kg, displacement ≦ 1 mm. However, because the currently marketed products must control the drilling depth or require special tools to use, the control does not expand well, which will affect the tensile strength and even lead to product falling out. The new internal screw length controls the expansion of the female member, and the full expansion does not cause the female member to fall out.

Detection

Test method (universal material testing machine): Take 3~5PCS before production to carry out concrete test block construction test. After the pull test is carried out by universal material machine, the test result must meet the established tensile data, then mass production can be carried out. After the production, the object 5~10PCS needs to obtain the relevant test data after being inspected by a third-party testing organization, and the relevant test data, the average data of the two or more. Taihao Warehouse Haojing Technology Co., Ltd. is located in No. 188, Luxin Road, Taicang City. It is a professional manufacturer of expansion screws.
