Application scope of new building formwork support
Application scope of new building formwork support
The new building formwork support is designed according to the residential standard floor. The system can be used in cast-in-situ reinforced concrete frame shear wall, frame, shear wall, brick concrete and other structural forms. For the materials below the standard floor, there is no separate addition of materials. When the materials of the standard floor are used below the standard floor, there may be a shortage of materials. The non-standard floor and basement can be used with the traditional wooden square tube, which can save the project cost.
(1) The new shear wall formwork support has the advantages of fast material preparation and high accuracy
The use of Shengchuan building materials formwork calculation software can quickly and accurately calculate the amount of materials required for the formwork support system, reduce the workload of construction technicians, and save about 8% of formwork materials compared with the self reduction of workers in traditional construction.
(2) The new shear wall formwork support uses steel instead of wood, which saves wood resources. The main and secondary back ribs (keels) of the formwork are made of steel, which replaces the square wood in the traditional formwork erection process, improves the service life of materials and saves wood resources.
The composition of formwork system mostly adopts socket and pin type, which is simple and convenient for installation and disassembly and fast construction speed. Compared with the traditional formwork erection process, it can improve the work efficiency by 25% ~ 30%; The formwork system is assembled in the form of loose assembly, the vertical wall structure and floor structure can be constructed at the same time, and the construction progress of large section steel formwork can be increased by 40% ~ 50%.
The formwork system has high strength and stiffness and good stability. The lateral pressure borne by the formwork can reach 65 kn / ㎡, which can accurately ensure the geometric dimension and surface flatness of concrete components and achieve the effect of fair faced concrete.
(features) the material (alloy steel) is retractable and suitable for various building types. It is not limited by the size of the room
It can be reused for 300 times (equivalent to 6-7 construction sites)
Fast disassembly and assembly speed, not easy to deform, save secondary plastering, save labor, time and materials, and reduce expenses
Carbon dioxide shielded welding is adopted at the welding position, which greatly ensures the quality of the welding position and increases the construction cost
Safety and product service life.
In addition, the internal and external anti rust technology electrophoretic paint is adopted (it can prevent rust under normal use)
(specification): 30mm * 50mm, length: 0.5m-3.4m, wall thickness: 2.30mm, (horizontal bar)
Specification: 40mm * 40MM, 50mm * 50, length: 2.2m-2.8m, wall thickness: 2.30m, (vertical bar)
(horizontal bar) consists of two 30mm × It is composed of 50mm rectangular steel pipe with wall thickness of about 2.3mm
The utility model has the advantages of retractability and convenient connection, replaces the traditional wooden square and round pipe, has a large stress surface, and can overcome the natural expansion
Mold phenomenon, improve work efficiency, and more importantly, it can make the wall more flat and firm.
(vertical bar) 1. It can expand freely and meet the use of walls with different heights. 2. It is not easy to run the mold, and the flatness is higher.
(internal angle) 90 ° angle, used for strengthening the internal angle of shear wall formwork to ensure the production quality of shear wall, and the operation is simple and fast
With the continuous development of society, the waste of resources is becoming increasingly prominent. In the construction industry, the consumption of wood resources is serious and the reuse rate is low, which increases the cost of the construction party and restricts the sound development of the industry.
