Under the background that China began to develop the processing and distribution of formed steel bars, the processing and distribution technology of building steel bars has been developed rapidly in recent years, which has become the inevitable trend of the technological progress and the transformation development of the construction industry. In modern industry, centralized processing and distribution of reinforcement can improve the utilization rate of reinforcement materials and the working efficiency of reinforcement processing and distribution, and ensure the production quality of reinforcement processing and distribution. The reinforcement processing and distribution technology has five aspects: equipment process automation, personnel level specialization, production management information, quality control standardization, processing and distribution industrialization.
For a long time, the traditional construction steel bars have been processed on the construction site by manpower. This processing method is characterized by high labor intensity, difficult to control the quality, low efficiency, high waste of materials and energy, and difficult to guarantee the progress of the project.
1. Connecting stirrup: material saving, high stability, mainly used for building frame column.
2. Stirrup processing products: Gutenberg editor reinforcement used to meet the shear strength of inclined section and connect the main reinforcement and the concrete reinforcement framework in the compression area.
3. The configuration of stirrups shall meet the requirements of stirrup leg distance and minimum stirrup ratio. The spacing of stirrups in the beam in article 10.2.10 of the concrete specification shall meet the following requirements:
(1) when the beam is equipped with longitudinal compression reinforcement required by calculation, the stirrup shall be made into closed type;
(2) the spacing of stirrups shall not be greater than 15d (D is the minimum diameter of longitudinal compression reinforcement), and shall not be greater than 400m;
(3) when there are more than 5 longitudinal compression bars in a layer and the diameter is greater than 18mm, the stirrup spacing shall not be greater than 10d;
(4) when the width of the beam is greater than 400mm and there are more than 3 longitudinal compression bars in one layer, or when the width of the beam is not greater than 400mm but there are more than 4 longitudinal compression bars in one layer, composite stirrups shall be set.
What is formed steel bar: a complete set of automatic steel bar processing equipment is used, such as CNC steel bar straightening and cutting machine, CNC steel bar hydraulic shearing production, CNC vertical steel bar bending center, etc. after a reasonable process, the steel bar is processed into various formed steel bar products required by the project in a fixed processing place, mainly including wire rod steel bar processing, bar steel bar processing and group. Processing of synthetic reinforced products. Wire rod reinforcement processing refers to reinforcement strengthening processing, reinforcement straightening and cutting, stirrup processing and forming, etc.; bar reinforcement processing refers to straight bar reinforcement cutting, reinforcement bending and forming, reinforcement straight thread processing and forming, etc.; combined forming reinforcement product processing refers to reinforcement welding mesh, reinforcement cage, reinforcement truss, beam and column reinforcement forming and processing, etc.
The computer information management of the whole process of the molding steel bars for the construction of dedicated Xinde includes the procurement of raw materials for steel bars, the generation of design specifications and parameters of finished steel bars, the decomposition of processing tasks, the optimized nesting of steel bars blanking, the processing of steel bars and finished steel bars, product quality inspection, product binding and packaging, the distribution of molding steel bars, the incoming inspection and acceptance of molding steel bars, contract settlement, etc. The formed reinforcement can be purchased directly from the construction site without secondary processing.
Hebei Jingye Xinde Reinforcement Engineering Co., Ltd. is a subsidiary of Jingye group, one of the top 500 companies in China. It was founded in July 2014 with a registered capital of 50 million yuan, an area of 37500 m2, and an annual processing capacity of 500000 tons of reinforcement.
The company has more than 50 sets of intelligent and automatic processing equipment, including: 600 type intelligent steel bar sawing and threading production line, BIM software system, steel bar processing robot, numerical control two-way mobile inclined bar bending center, numerical control vertical steel bar bending center, numerical control hydraulic steel bar cutting production line, steel bar cutting machine, numerical control steel bar straightening and cutting machine, bending machine, numerical control steel bar bending hoop. Machine, intelligent CNC bending, straightening and sizing and other domestic advanced processing equipment. It can produce stirrup, beam reinforcement, welded mesh, reinforcement cage and other types of building shaped reinforcement products, and provide users with one-stop services such as steel bar proofing, actuarial, construction control, binding, etc. Business has been extended to Dubai, South Korea and New Zealand.
Raw material warehousing and inspection - production blanking - processing and forming - binding and packaging - finished product inspection - finished product warehousing - finished product delivery
1. All of them use professional CNC processing equipment with high degree of intelligence, automation and informatization, which is in line with the national policy concept of "environmental protection, energy saving and efficiency".
2. Safety: reliable raw materials. The raw materials are professional group screw steel, screw and round, with complete specifications and reliable quality.
3. Environmental protection: the processing plant is located far away from the residential area, and the plant is completely closed to avoid noise disturbing the residents; the reinforcement processing is completed in the plant, which saves the field processing site, reduces the investment in environmental protection, and helps the construction site to be civilized, clean and environmental management.
4. The product quality is guaranteed: the CNC steel bar processing equipment is adopted, the blanking size error is small, and the processing and forming accuracy is high. Raw materials and finished products shall be stored indoors without corrosion, so as to effectively ensure the quality of reinforced concrete components.
5. The construction schedule is guaranteed: the large-scale production mode is adopted, the unit time output is high, which can meet the mass production demand of the construction site, at the same time, it is not affected by the natural conditions, and it can be produced 24 hours a day, greatly shortening the construction period.
The company is committed to do a good job as a reinforcement service provider, to provide customers with better, faster and more thoughtful value-added services
