Designing a Wooden Rigid Frame Bridge Model

Introduction: Designing a Wooden Rigid Frame Bridge Model

For students, hands-on is a good way to learn. By making architectural models, students can make full use of the theoretical knowledge learned in the classroom and use their imagination.

The theme of this project is construction technology, and it is designed for grade 6 students, technology. At this stage students need to learn the structure of the building and make their own building models. And this project chose the most common and most representative architectural model as the theme which is rigid frame bridge. And hope that through this project students can understand the importance of the use of triangles in building structures, and develop the habit of drawing design drawings before production.

Supplies

1/8 Inch wooden Square Dowel Rods

super glue

Cutting tools (such as knives, or saws)

Blank paper

Ruler

Pen and pencil

(Total $ 5 per person)

Step 1: Design Drawing

First, draw the structural design of the bridge. Students are free to design their own bridges, but they must conform to the basic shape and structure of the bridge. This is the most critical step. Although this project gives students a lot of freedom to play, the design part is essential. Only when there is a correct design drawing can a good model be made. And a accurate design drawing can also make subsequent work more convenient.

Step 2: Making the Side of the Bridge

Cut the wood according to the drawing, and then glue the pieces together as shown on the drawing and glue them together with super glue. Compared to drawing a design diagram, this step is relatively simple, but it will take a lot of time, and test the students' hands-on ability and fineness of operation.

Step 3: Make the Other Side of the Bridge

Repeat the second step to make the other side of the bridge. Note: The key to bridge stability is to look at the fineness of the production on both sides. If the similarity between the two sides is higher, the bridge is more stable and can bear more weight.

Step 4: Connect the Two Sides of the Bridge Together

The final step is to connect the two sides of the bridge together to form a complete bridge model. This step should be relatively simple if the first two parts are better. Of course, students can also freely choose the connection method they like. The finished bridge should be relatively strong and able to carry a certain weight. If time is available, the teacher can measure the load-bearing capacity of the bridge with the students.

Finally, remember to clean the classroom after completing the project
