Nanchang Weifengdian Building Materials Co., Ltd. introduces the analysis of the reasons for the deformation of formwork panels. Formwork panels are temporary supporting structures, manufactured according to design specifications to shape concrete structures and components into the required positions and geometric dimensions, maintaining their correct placement and bearing the weight of the formwork and external loads acting upon it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete projects, accelerate construction progress, and reduce engineering costs. However, after some time in use, formwork panels often deform. What are the reasons for this deformation?
1. The assembly of Xiangyang engineering boards was not set according to specifications, resulting in poor overall building performance. 2. The base on which the formwork was placed was unstable, the boards were not properly set, and poor anti-slide measures led to settling of the foundation. 3. Wooden formwork or plywood was used for construction, and concrete pouring was not timely after inspection, leading to surface damage from long-term exposure to sunlight and rain.
1. Poor support spacing and insufficient rigidity of steel plates.
2. Excessive concrete pouring speed for wall columns, with overly high single pour height and excessive vibration.
During the construction process, engineering board manufacturers must use molds that comply with their construction standards. Due to variations in materials and specifications, the bearing performance also differs. It is necessary to use the appropriate products to avoid cracking caused by excessive load. Different raw materials also affect the overall strength and quality. To ensure construction quality and efficiency, we need to differentiate strengths during procurement. Environmental factors also influence the overall strength to some extent. In dry areas, the moisture content within the structure can easily evaporate, leading to an increasing internal stress and potential cracking. To address this, we must adjust the dryness level of the surrounding environment to reduce its impact on the products. The surface should be cleaned before use, as any residue may affect the cleanliness of the construction surface. Use soft tools when cleaning to avoid damaging the internal structure due to excessive force or hard tools. Store them indoors, and cover them when concrete is not being poured to prevent exposure to sunlight and rain, which can cause cracking in the boards and shorten their lifespan. Handle the boards with care during use, strictly prohibit rough handling, and avoid excessive force to prevent damage that could impact the construction process and waste materials.
