What Should Be Paid Attention to In The Process of Demolding of Common Building Formworks? As we all know, building formwork plays a pivotal role in the process of engineering construction, because it can effectively ensure the safety of construction, so what should we pay attention to in the process of demolding of building formwork? 1 Building formwork demolding time The demolition of the building formwork shall be based on the compressive strength report of the concrete test block under the same conditions, and then the application form for demolition shall be filled in, signed by the professional foreman and the project technical person, and submitted to the supervisor for approval before it becomes effective. Side form: The side form can be removed only after the concrete strength can ensure that the surface edges and corners are not damaged due to the removal of the building formwork. Bottom form: The bottom form can only be removed after the concrete strength of the componen

Steel Formwork VS Wooden Formwork

Steel Formwork VS Wooden Formwork Some building formworks are often used in some large-scale projects, and these building formworks can often play a good supporting and fixing role. There are many types of formwork materials on the market, and companies often need to compare different formworks to make a better choice. Next, let's take a look at the difference between steel formwork and wooden formwork. 1. What is steel formwork? And what is wooden formwork? From the material point of view, the steel formwork is made of steel and the wood formwork is made of wood. Steel formwork for concrete is generally made according to the modulus size. After the concrete is demolished, the concrete surface is still relatively smooth and beautiful. The steel formwork can be placed before or after the installation of the reinforcement. The steel formwork is placed before the steel bars are installed, which is convenient and easy to place and install. It can visually monitor the concrete pour

Comparison and Analysis of Common Formwork Types in Construction Engineering

Comparison and Analysis of Common Formwork Types in Construction Engineering In recent years, the construction industry has developed rapidly, which has brought a larger and more diversified use of building formworks. Nowadays, building formworks can be divided into the following formwork types. 1. Steel formwork Steel formwork can be divided into small steel formwork and large steel formwork. The average weight of the small steel mold is about 50-60kg/m2, and mechanical equipment must be used for hoisting. There are also more seams when used, so the frequency of use in existing projects has decreased. The average weight of the large steel mold can reach more than 100kg/m2, and it is completely dependent on mechanical hoisting in use. The advantage is that there are fewer splicing joints and the overall flatness of the concrete is high. The steel formwork needs to be actively maintained during on-site use, or the surface quality of the concrete will be greatly affected. Large steel

Causes of Deformation of Building Formwork and Remedial Measures

Causes of Deformation of Building Formwork and Remedial Measures 1. Causes of deformation of building formwork are as follows: (1) The support spacing between building formworks is too large, and the rigidity of the steel plate is poor; (2) When assembling small steel formwork , it is not set and operated according to regulations, resulting in the poor overall performance of the building; (3) The speed of pouring wall and column concrete is too fast, the height of one-time pouring is too high, and the vibration is excessive; (4) The foundation on which the building formwork is placed is not firm, resulting in the formwork not being laid flat and poor waterproof measures. So it caused the foundation to sink; (5) The construction site adopts a wooden building formwork or plywood construction, and the concrete is not poured in time after passing the experience. Long-term sun and rain cause varying degrees of deformation of the building formwork surface; (6) The construction personn

Usage and Maintenance of Building Formwork

Usage and Maintenance of Building Formwork Appropriate maintenance and correct use of building formworks can not only extend the life span but also reduce a lot of unnecessary troubles for the construction project. So how can we extend the service life of building formworks? Ⅰ. The formwork must be covered during transportation. When transporting the building aluminium column formwork , it should be noted that a transport tool with a better shielding effect should be selected. Or it can be covered with plastic cloth or thin felt to avoid the sun and rain during transportation and prevent the building formwork from being severely deformed in a short time due to the natural environment. Ⅱ. Place the building formwork neatly after unloaded to prevent sun and rain. After unloading the truck, the formwork should be neatly stacked on the flat ground. It should be noted that the board surface should not be in direct contact with the ground, and wood should be used to separate it layer by l

Advantages of Building Formwork.

Advantages of Building Formwork. Ⅰ. What is a building formwork Building formworks have a wide range of applications in people's daily lives and can be seen everywhere. The building formwork is a temporary supporting structure. It is made according to the design requirements so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct position, and bear the weight of the building formwork and the external load acting on it. The purpose of building formwork projects is often to ensure the quality and safety of concrete projects, speed up construction progress and reduce project costs. Ⅱ. Eight advantages of building formwork As a widely used building material, building formwork has eight irreplaceable advantages. (1) Smooth and clean. The formwork is tightly spliced and smooth, and the surface and smoothness of the concrete structure after demolding exceed the technical requirements of the existing clear

Assembly And Disassembly of Bridge Formwork

Assembly And Disassembly of Bridge Formwork Ⅰ. Assembly of bridge formwork When assembling the bridge formwork, especially when shaping the bridge steel formwork, we need to pay attention to the following issues: (1) All components of the table formwork construction system are complete and firmly connected. The assembled formwork should be placed neatly according to its structural characteristics to ensure stability. (2) Professional technicians must be arranged for technical guidance on the assembly site. (3) Before assembling the formwork, check the components of the formwork system and inspect the appearance. Components with serious defects, bumps, deformation, etc. shall not be used. (4) Steel bridge formwork is used for concrete pouring and molding. Metal formwork is widely used in construction projects due to its multiple-use and beautiful appearance of concrete pouring. During the installation and use of bridge steel formwork, we must assemble in accordance with regulat
