Considerations When Designing Bridge Formwork

1. What should be understood in the design of bridge formwork?


When designing a bridge template, in order to achieve the overall effect, it is necessary to pay attention to the processing of every detail in each design step, so that the effect can be presented in the future use, so what do we need to know when designing?


First of all, under the action of the load, the strength, stiffness and stability of the special-shaped formwork should be calculated according to the force program. The formwork should be able to reliably withstand various loads that may occur in the construction process, and ensure that the shape and size of each part are accurate. Economical, taking into account both safety and economic benefits.


In short, it is the selection of models, materials, drawing of general assembly drawings, detailed structural drawings, and preliminary design.


The second is that the surface of the formwork should be flat, the joints should be tight, and the slurry should not leak, so as to ensure that the exposed surface is beautiful and the lines are smooth. The strength, stiffness and stability are checked under the calculated load, and the formwork material quantity table is also compiled.


It is also necessary to look at the presentation effect. It is required that the template has a simple structure and is easy to manufacture and disassemble. It is also necessary to understand the technical measures and precautions for the installation, use, disassembly and maintenance of the template.


In short, we should pay attention to the above aspects when designing the bridge formwork.


2. Issues to be considered in the design of bridge formwork


The bridge formwork needs to be standardized when designing, and there are still many requirements in the design process, so we must pay attention to the corresponding problems, so that the subsequent use can be smoother and reduce the occurrence of various problems, it should be considered What's the problem?


Generally, there are many issues that need to be considered in the design process of bridge formwork, among which the main problems include: the design of the formwork should conform to the engineering structure drawings; the formwork should be simplified and the design should be simplified under the premise of meeting the strength of use, so that the structural design is reasonable; the formwork is divided into blocks The design should take into account the ease of use of the construction site, that is to say, a good formwork is easy to remove the formwork; the design of the formwork should take into account the manufacturability of processing; the design of the formwork should take into account the transportation problem.


Matters needing attention in the actual computer drawing process. Rotate the bolt screw to make the cylinder mold in place according to the line, and install the back reinforcement purlin and wall bolts. Note that the connection of the construction joint template must be tight, firm and reliable to avoid misplacement and slurry leakage.


The base material of the bridge shuttering must be dry. Before use, it should be treated to remove floating dust and oil to improve the adhesion of the formwork paint to the base material. The formwork paint should not be applied too thickly. Flow phenomenon, the dosage is generally 20 m/kg. The formwork paint is painted on the formwork, and the surface is generally dry for 20 to 30 minutes, smooth and smooth, avoiding dust pollution. The formwork paint needs to be dry before pouring concrete.


The bridge template design process should pay attention to the above content, the processing of every detail will affect the use effect, so we should pay attention to these aspects. Consideration can be made in the future use more smoothly and reduce the occurrence of various problems.
