Foot cage

Definition and Structure

Definition: Foot cage, also known as ground cage or foot embedded parts, is a type of embedded part used to fix buildings, equipment, etc. on the foundation.

Structure: Usually composed of screws, connecting rods, sleeves, bent feet, positioning blocks, and other components. The screw is the main load-bearing component, which is connected to the connecting rod, bent foot, etc. through a sleeve to form a stable frame structure. The positioning block is used to determine the position and direction of the screw, and to confirm the accuracy of the installation of the foundation cage.

Specification and size

The specifications and dimensions of the foundation cage are usually determined by factors such as the height of the embedded parts, the number of screws, the thickness and model of the bolts, the diagonal distance of the embedded bolts, and the thickness of the panel. For example, the common street lamp pole ground cage has a standard size of 160mm × 160mm × 400mm for a 4-meter pole ground cage, with a bolt specification of M14; The standard size of the 10 meter lamp post ground cage is 240mm × 240mm × 900mm, and the bolt specification is M20.

Material and Characteristics

Material: Mainly steel metal, such as Q235 steel, Q345 steel, etc., galvanized steel material is also used to improve rust resistance, and stainless steel material is also used in special requirements.

characteristic

Sturdy structure: capable of providing stable support for buildings or equipment, ensuring that they will not experience displacement or shaking during use.

Easy installation: Simply embed the foundation cage in the foundation, and after the foundation concrete solidifies, connect and fix the equipment or structure to the foundation cage. The construction process is simple and fast.

Strong adaptability: Different specifications, sizes, and structural forms of foot cages can be designed and manufactured according to different usage needs and basic conditions, suitable for various types of buildings and equipment.

purpose

Street lighting engineering: used to fix lighting equipment such as street lamp poles, high pole lights, landscape lights, etc., to protect the stability and safety of the lamps and ensure their normal operation.

The construction of transportation facilities, such as road sign posts, traffic signal poles, and highway guardrail columns, plays an important role in guiding traffic and protecting traffic safety.

Industrial equipment installation: Large mechanical equipment such as machine tools, generators, compressors, etc. need to be fixed on the foundation with foot cages to prevent displacement or damage due to vibration during operation.

Steel structure buildings: In steel structure factories, warehouses, and other buildings, foundation cages are used to connect steel columns to foundations, transfer loads, and protect the stability and integrity of steel structures.

Installation method and precautions

installation

Excavation: Strictly follow the dimensions of the design drawings, excavate the pit along the road direction or equipment installation position, and confirm that the size and dimensions of the pit meet the requirements.

Placing the foundation cage: Place the foundation cage in the pit and measure it using a spirit level and angle ruler to ensure that the upper surface of the foundation cage is level and the foundation bolts are perpendicular to the upper surface of the foundation.

Pouring concrete: After the foundation cage is installed in place, use C20 or other concrete with the required design strength for pouring. During the pouring process, use a vibrating rod to vibrate the concrete to make it compact and confirm that the foundation cage is tightly combined with the foundation.

precautions

Foundation treatment: Before installing the foundation cage, the foundation needs to be treated to confirm that its strength and stability meet the design requirements. If the foundation soil is soft or there are problems with groundwater, corresponding reinforcement or drainage measures need to be taken.

Foot cage protection: During the construction process, attention should be paid to protecting the foot cage to avoid damage or contamination of the foot bolts. Wrap the anchor bolts with tape to prevent splashing of cement residue.

Concrete curing: After pouring is completed, it should be cured according to the requirements of concrete curing, watered regularly, and confirmed that the concrete reaches the design strength within the specified time before proceeding with subsequent equipment installation work.
