The composition and advantages and disadvantages of steel formwork materials

About the composition of steel formwork materials, Wangke, Hubei Template Co., Ltd. is introduced as follows:

Combined steel template processing and manufacturing of various materials, the main materials are steel plates, section steel; auxiliary materials are welding rods, paint The raw materials of various materials should meet the rules of relevant national standards. The main steel material is Q235. The quality grade can be A, B or C, and the deoxidation method should be steel Z. The raw material of the general steel plate should be before the template manufacturing. , Re-examine or inspect according to the relevant current national standards. At present, the steel materials used by many manufacturers for steel formwork do not meet the requirements of the standard, and even some manufacturers choose to use remanufactured steel to process steel formwork, which is not satisfied with the construction requirements. In addition, many steel formwork factories choose the steel plate thickness name as 2.50mm, which is actually only 2.20mm~2.30mm. The rigidity and strength of the steel formwork cannot be guaranteed, which seriously affects the manufacturing quality and application effect of the steel formwork.

In the original standard, the raw material of scaffolding steel pipe is Q235, because low-alloy steel pipes have remarkable physical and mechanical properties Better than ordinary carbon steel pipes, Q345 is widely used as raw material for scaffolding steel pipes in developed countries. At present, many domestic scaffolding companies have also selected Q345 steel pipes. Therefore, in the revised standard, the raw materials of steel formwork and steel pipes should be compensated accordingly, and the steel formwork for steel processing should be completely changed.

Briefly describe the advantages and disadvantages of composite steel templates

What are the advantages and disadvantages of combined steel formwork compared with traditional wooden formwork and old-style steel formwork? The editor will take you to find out.

First, the advantages of combined steel template

(1), the application scale is wide, suitable for different project scales, structural forms and construction techniques, on-site Assembly, overall hoisting, sliding form, climbing form, etc.;

(2), long service life, high component strength, good durability, quick turnover, if repaired in time . Properly protected, it can be used for a long time;

(3), the plate manufacturing precision is high, the joints are tight, the rigidity is large, the deformation is not easy, and the formed concrete structure Accurate scale, compact and bright;

(4). The combined rigidity is large, the plates are arranged in staggered seams, and the assembled panel has the overall rigidity of the plane; The combined column and beam formwork itself is a load-bearing component, which can improve the overall rigidity, facilitate overall hoisting, and simplify the support structure.

2. Disadvantages of combined steel template:

(1). The one-time purchase investment is large and the cost recovery period is long. Therefore, the use of combined steel templates must be strengthened Protect and maintain, accelerate turnover, and increase the frequency of use to improve economic efficiency;

(2), because the surface of the poured concrete is too smooth, the adhesion is poor, which is not conducive to the appearance of decoration, and sometimes it is necessary Perform chiseling treatment.
