M16 Expansion Shell Rock Bolts

M16 Expansion Shell Rock Bolts

M16 Expansion Shell Rock Bolts are crucial elements in stabilizing rock formations in various industries, from mining to civil engineering.
They are used to reinforce and support rock structures to prevent them from collapsing or shifting, which can pose a serious threat to workers and structures.
There are several types of rock bolts, each designed for specific applications. Here are some common rock bolt applications and types you should know.
These rock bolts consist of a steel tube and an expansion shell that is inserted into a drilled hole in the rock. A cone-shaped wedging expansion shell is connected to the tube and expanded by using a mechanical tool or hydraulic pressure. This creates a compressive force that anchors the bolt into the rock, providing additional support and stability.

Ground Tunnelling Expansion Shell Rock Bolt

Ground Tunnelling Expansion Shell Rock Bolt

Ground Tunnelling Expansion Shell Rock Bolt is a kind of rod that is anchored in the rock mass.
The use of anchor bolt to support the roadway is to drill holes in the surrounding rock after the roadway is driven, and then install the anchor bolt in the eye to strengthen the surrounding rock of the roadway manually.
The anchor rod has many advantages: saving pit wood and steel, reducing support costs, small excavation section, small deformation of the roadway, low maintenance costs, safety, portability, can reduce physical labor, reduce ventilation resistance, is conducive to the construction of a lane and speed up the excavation speed, wide range of use,strong adaptability, reduce the amount of transportation, is conducive to the transportation and upgrading of the mine. However, the bolt can not prevent the weathering of surrounding rock, can not completely prevent the fracture rock spalling between the bolt and the bolt, therefore, the bolt combined with other supporting measures, such as metal mesh, will achieve better supporting effect.

Expansion Shell Roof Bolts

Expansion Shell Roof Bolts

Expansion shell roof bolts are a type of fastener commonly used in construction and mining to secure heavy loads to concrete or other solid surfaces. These bolts consist of a threaded metal rod with a flared cone-shaped end that is inserted into a pre-drilled hole in the surface. When a nut is tightened onto the threaded end of the bolt, the cone-shaped end expands, pressing against the sides of the hole and providing a secure anchor point.

Bonded Post-Tensioning System Anchor

Bonded Post-Tensioning System Anchor

You can rest assured to buy Bonded Post-Tensioning System Anchor from our factory. Bonded Post-Tensioning comprises tendons from one to multiple strands (multistrand) or bars. For bonded systems, the prestressing steel is encased in a corrugated metal or plastic duct. After the tendon is stressed, cementitious grout is injected into the duct to bond it to the surrounding concrete. Besides, the grout creates an alkaline environment which provides corrosion protection for the prestressing steel. Bonded multi-strand systems, while used extensively in new construction of bridges and transportation structures, can be and have been successfully applied to commercial building structures. When these multi-strand systems are used for large structural elements such as beams and transfer girders, design advantages include increased span lengths and load carrying capacity and reduced deflection.

Post Tension Prestressed Flat Slab Anchorage

Post Tension Prestressed Flat Slab Anchorage

Post Tension Prestressed Flat Slab Anchorage refers to a type of anchorage system used in the construction of flat slab structures. It consists of a set of prestressing cables that are anchored to the concrete slab using specialized anchorages. These anchorages are designed to withstand the high tension forces generated by the prestressing cables, which are used to counterbalance the weight of the structure and strengthen it against external loads.

Unbonded Post-Tensioning System MonoStrand Anchor

Unbonded Post-Tensioning System MonoStrand Anchor

You can rest assured to buy Unbonded Post-Tensioning System MonoStrand Anchor from our factory. Unbonded Post-Tensioning typically consists of single (mono) strands or threaded bars that remain unbonded to the surrounding concrete giving them the freedom to move locally relative to the structural member. The strands in unbonded mono strand systems are coated with specially formulated grease, with an outer layer of seamless plastic extruded in one continuous operation to protect against corrosion. It is e typically used in new construction for elevated slabs, slabs-on-grade, beams and transfer girders, joists, shear walls and mat foundations. Light and flexible, unbonded mono strand can be easily and rapidly installed – providing an economical solution.
