PC truss reinforcement

PC truss reinforcement is a type of steel component used in prefabricated concrete structures, also known as truss reinforcement. Here is a detailed introduction about it:

Structural composition
PC truss reinforcement is composed of one upper chord steel bar and two lower chord steel bars arranged in a triangle shape, connected by two long wavy bent belly bar steel bars to form a steel skeleton with an inverted V-shaped cross-section.

role
1. Enhanced connection: Connect the prefabricated truss panels in the reinforced concrete composite panel with the cast-in-place concrete composite panel, enhance the shear resistance of the contact surface between the two, and improve the overall integrity of the reinforced concrete composite panel.
2. Material saving: When the steel reinforcement configuration in the prefabricated truss panel is appropriate, the lower chord steel reinforcement of the steel truss can replace some of the steel reinforcement in the prefabricated truss panel, thereby saving the total amount of steel reinforcement used.
3. Acting as a suspension point: By strengthening the structure, the steel truss can have the function of a suspension point, without the need to separately set up suspension points for prefabricated truss panels.
4. Increase support spacing: During the construction phase, the role of steel truss can be considered to increase the temporary support spacing under the prefabricated truss slab to reduce the number of supports.
5. Control the thickness of the protective layer: During construction, it can also serve as a horse stool reinforcement for the steel mesh inside the cast-in-place concrete composite panel, providing support for the steel bars inside the cast-in-place concrete composite panel, while controlling the thickness of the steel bar protective layer.

application
PC truss reinforcement is mainly used in components such as composite panels and composite wall panels in prefabricated concrete structures. In composite panels, it can effectively improve the connection performance between prefabricated panels and post poured concrete layers, enabling the composite panels to better withstand loads during use. In laminated wall panels, it is not only the connecting component between precast concrete and cast-in-place concrete, but also the key component for supporting and connecting precast inner and outer panels.

characteristic
1. Automated equipment production, low consumption, high production capacity, and low labor costs.
2. The truss has a reasonable stress mode, economical material selection, and comprehensive cost advantages.
3. The workload of on-site steel bar binding has been reduced by 60% to 70%, which can shorten the construction period.
4. The product quality is stable, and it can be applied to large-span floor slabs by adjusting the truss height and steel bar diameter.
5. The mechanical properties are basically equivalent to traditional cast-in-place, and the crack resistance is good.
