Push-Type Floor Machine and Push-Type Slab Machine: Revolutionizing Prestressed Hollow Slab Production
In the era of prefabricated construction, the push-type floor machine—also referred to as the push-type slab machine—has become a cornerstone of efficient and intelligent floor slab production. This highly specialized equipment is designed for the continuous, mold-free manufacturing of prestressed hollow core slabs, which are widely used in residential, commercial, and industrial building projects.
By combining mechanical precision, material optimization, and prestressing technology, push-type machines significantly improve productivity while reducing structural weight, making them ideal for modern large-span floor systems.
What Is a Push-Type Floor Machine?
A push-type floor machine is a type of extrusion-based equipment used to form long, prestressed concrete floor slabs—particularly losas alveolares—without relying on individual molds. Instead of traditional casting, this machine uses a screw propeller or a similar pushing mechanism to extrude concrete along a continuous path, shaping it into high-strength slabs that include internal hollow cores for weight reduction and cost savings.
En push-type slab machine plays a vital role in prefabricated component factories, where consistency, speed, and strength are critical production factors.
Working Principle of the Push-Type Slab Machine
The core working principle of the push-type slab machine lies in the extrusion of concrete under pressure, combined with vibration and compaction for structural density. Here’s how it works step by step:
1. Arrangement of Prestressed Steel Strands
For prestressed slab production, high-tensile steel strands are arranged on the casting bed in advance. These strands are tensioned to introduce internal compressive forces that enhance the slab’s load-bearing capacity and reduce cracking.
2. Alimentación de hormigón
A precisely proportioned concrete mixture—usually a dry mix with high workability—is poured into the feeding hopper of the machine. The mix contains cement, sand, aggregates, water, and sometimes chemical admixtures.
3. Extrusion and Forming
As the push-type floor machine moves along the casting bed, its internal screw propeller pushes the concrete forward, while internal vibration units compact the material. Simultaneously, core tubes or molds inside the machine create longitudinal hollow voids within the slab.
4. Surface Finishing and Pre-Hardening
As the slab is extruded, surface treatment tools smooth the top surface. The slab is left to pre-harden under ambient or controlled conditions before cutting and curing.
5. Cutting and Curing
Once the concrete reaches adequate strength (usually within 12–24 hours), slabs are cut to length using automatic cutters. The finished pieces are then moved to steam curing chambers or natural curing zones for strength development.
Key Advantages of Push-Type Floor and Slab Machines
✅ High Production Efficiency
The push-type forming process enables continuous slab production, reducing downtime and increasing daily output compared to traditional mold casting.
✅ Mold-Free System
Eliminating the need for individual molds lowers equipment investment and maintenance costs, simplifies operations, and reduces material sticking or waste.
✅ Prestressing Capability
Built-in prestressing technology strengthens slabs for long spans y high load demands, while reducing slab thickness and material usage.
✅ Lightweight Design
En hollow core design decreases the self-weight of slabs without compromising structural integrity—ideal for high-rise buildings, parking structures, and bridge decks.
✅ Uniform Quality and Automation
Automated feeding, vibration, extrusion, and cutting ensure uniform slab size, smooth finishy minimal human error, leading to better consistency in construction.
✅ Material Savings and Eco-Friendliness
By using hollow sections and optimized mix designs, the machine helps save up to 30% of concrete materials, making it an environmentally and economically sound choice.
Applications of Push-Type Slab Machines
The slabs produced by push-type floor machines are widely used in:
- 🏢 Naves industriales – For long-span roofs and floors requiring heavy load-bearing.
- 🏘️ Proyectos residenciales – As floor decks in apartment complexes, villas, or modular housing.
- 🏬 Edificios comerciales – For high-rise offices, malls, and logistics centers.
- 🏗️ Proyectos de infraestructuras – Such as bridges, tunnels, and parking garages.
These machines are ideal for prefabrication plants, precast concrete suppliers, or developers aiming for modular, fast-track construction solutions.
