II. Introduction to the Unassembled Formwork Truss Floor Project

1. Project overview

The unassemble formwork reinforced truss floor uses a new type of green board. The bottom board is made of cement and quartz sand as the main materials, with imported natural wood pulp as the main reinforcing fiber. It is made by special formwork pressed under high pressure and steam oxygen at high temperature. Its surface has regular groove texture, which can improve the adhesive strength between the board and the concrete or mortar by more than 50% compared to ordinary flat plates. It effectively solves the problem of detachment caused by poor adhesion between the board and the concrete or mortar and restricts board deformation, thereby solving the problem of cracking of the finish caused by board deformation.

The new green bottom board is fixed to the reinforced truss using special self-tapping screws and the connection base of the automatic screw-locking machine. It realizes mechanization and industrial production, with simple construction technology, convenient construction and transportation, flat surface of the bottom board. It can completely replace the laminated boards and cast-in-place floor framework currently available on the market, achieving disassembly-free, plaster-free, quick installation, reducing construction processes, lowering transportation costs, almost no loss, ensuring indoor net height, and reducing construction costs, etc. It greatly solves the known problems existing in the use of laminated boards in prefabricated houses and can be widely used in various building projects such as hotels, office buildings, schools, residential buildings, hospitals, warehouses, parking lots, and multi-story industrial buildings. It is one of the new options for floor construction in prefabricated buildings, with enormous market potential.

III. Equipment Performance and Technical Parameters

1.Technical Parameters of Steel Joist Production Line

1.1 Equipment Overview

Square tube rebar truss production line is a fully automated production line integrating rebar coiling release, rebar straightening, side bar bending, weld forming, automatic shearing, and finished product gathering, which can produce non-demolition molded rebar trusses, rebar trusses for floor joists, and PC rebar trusses for assembled buildings, which are widely used in the fields of building construction (prepositioned floor joists) and high-speed railroad (double-block railroad sleeper) construction.

Welding equipment for square tubes:

1.2 Equipment Composition of Rebar Truss Production Line:

1.3 Equipment Technical Parameters:

1.4.1 Equipment Features

1. Rubar laying frame

l There are five sets of bar payoff stands, using rotating payoff method, with a maximum load of 2 tons.

l Each payoff stand is equipped with independent air braking device.

l Each payoff stand has an independent pre-straightening mechanism to remove the oxide scale on the surface of the steel bars.

2. Straightening and Feeding Mechanism

l It uses multi-wheel straightening with good straightening effect, without damaging the ribs of the steel bars. Three deceleration motors are used for feeding.

l Each feeding mechanism can be controlled independently.

3. Steel Bar Storage Mechanism

lIt adopts a new type of open storage rack for buffering and storage, which is convenient for continuous production and effectively prevents steel bars from tangling.

4. Terminal Straightening Mechanism

l Secondary terminal straightening is performed on the main bar and the web bars before welding and forming. Five-roll straightening is used to ensure the straightness of the finished truss.

l This mechanism plays a key role in adjusting the straightness of the truss products.

5. Web Bar Pressing and Feeding Mechanism

l Swing-arm bending is used for bending the steel bars, powered by a servo motor, with good synchronization and high stability.

l Steel bar bending is continuous (the bending mechanism works in a circular and up-and-down swinging motion, without delay), with fast forming speed.

l The steel bar forming molds have cylindrical surfaces to prevent scratching the surface of the steel bars.

6. Welding Part

l Two spot welders, one on the top and one on the bottom, with two transformers in total.

l Four lower press rollers with good synchronization.

l The welding cylinders have a small stroke, large force, fast welding speed, and high quality.

l The welding cylinders use high-quality brands and are air clamped.

l The welding electrodes are made of chrome-zirconium alloy copper.

l Equipped with positioning mechanism to ensure the shape and size of the welding.

l The two-point resistance spot welding method reduces the installation power by 60% compared to peers, and the welding parameters of each welding point can be set independently.

l The four-way electrode head can be reused four times, reducing the cost by 3 times.

7.Square tube welding mechanism

lThe vibrating plate is used as the loading mechanism, and the loading speed is Stable and high efficiency. Square pipe pushing is completed by high-speed cylinder, and welding is completed by resistance welding.

8.Cutting Mechanism

l The "scissor-type" cuttingmode is adopted to effectively solve the problem of open weld caused by cutting process and avoid deformation and distortion of the truss during cutting.

l Fast cutting speed, no need to stop welding.

l For high-strength cutting at the main and side reinforcement welding joints, the latest developed high-strength and tough mold steel from China is used.

8. Automatic Collection and Stacking Mechanism

l The automatic collection mechanism allows continuous production without the need to stop, improving efficiency.

l It can collect trusses of different sizes, long and short.

l The automatic collection, stacking, and shipping of trusses are all fully automated.

l The automated collection and stacking device reduces the number of operators by 2.

10. Electrical Control System

l It adopts the control system from Hechuan with high stability.

11. Operating System

l Operating buttons and other components use high-quality products.

l The equipment is easy to operate and adjust.

l Operations such as speed, welding parameters, etc. are convenient.
