With the arrival of winter, the temperature gradually decreases, bringing many challenges to the construction of steel mold plate for bridges and other construction projects. In order to ensure the construction quality and safety, pansol steel formwork manufacturers for the world’s engineering and construction personnel to organize a winter steel formwork construction precautions for your reference.

1, steel formwork preparation and installation
(1) Selection of steel formwork: In winter construction, steel formwork with high strength, abrasion resistance and good frost resistance should be selected. Zhongtai steel mold plate manufacturers produce steel mold plate after strict quality testing, can maintain stable performance in low temperature environment.
(2) Template preheating: Before installation, the steel formwork can be preheated appropriately to reduce the temperature difference between the formwork and the concrete, to prevent deformation of the formwork or cracking of the concrete due to excessive temperature difference.
(3) Installation accuracy: In the low-temperature environment, the installation accuracy of steel formwork is easily affected. Therefore, during the installation process, the verticality, horizontality and splicing gaps of the formwork should be strictly controlled to ensure the overall stability and dimensional accuracy of the formwork.

2、Concrete pouring and maintenance
(1) Concrete temperature control: before pouring, the temperature of concrete should be ensured to be suitable, to avoid too low temperature leading to slow concrete solidification or cracking. At the same time, pay close attention to the weather forecast to avoid pouring in extreme low temperature weather.
(2) Pouring speed: In winter construction, the pouring speed of concrete should be accelerated appropriately to reduce the exposure time and heat dissipation of concrete.
(3) Custodial measures: After the pouring is completed, thermal insulation measures should be taken in time, such as covering plastic film, quilts, etc., to reduce heat dissipation. Meanwhile, the humidity of the curing environment should be maintained to prevent the concrete from cracking due to drying.

3, construction safety management
(1) Anti-skid measures: the construction site is prone to ice in winter, anti-skid measures should be done in advance, such as laying anti-skid mats, spreading sand, etc., to ensure the personal safety of construction workers.
(2) Electricity safety: when using temporary heating equipment at the construction site, attention should be paid to electricity safety to avoid electrical fires and electrocution accidents.
(3) Operator training: Strengthen the safety training for operators to improve their safety awareness and operation skills. Especially in low temperature, wind and snow and other adverse weather conditions, make sure that the operators are familiar with the emergency plan and escape routes.

4、Quality Acceptance and Post-Maintenance
(1) Quality acceptance: After the construction is completed, the quality of concrete and the deformation of steel mold plate should be accepted and evaluated. Ensure that the concrete meets the design requirements and the steel mold plate has no serious deformation or damage.
(2) Post-maintenance: At the end of winter construction, the steel formwork should be cleaned and maintained to remove the concrete residues and debris such as ice and snow adhering to the formwork. At the same time, the deformation and damage of the template should be checked, and the damaged template should be replaced and repaired in time.

In short, winter steel formwork construction requires special attention to temperature control, construction safety and quality acceptance, etc. pansol steel formwork manufacturer reminds all construction personnel to make full preparation and countermeasures before construction to ensure construction quality and safety. At the same time, it is also hoped that the construction personnel can strengthen the learning and communication, and constantly improve their professional skills and level.
