How to build a paper bridge

Paper Bridge Method: Prepare: (1) 4 or 5 book cards (such as boxes for miscellaneous items) (2) 1 piece of corrugated cardboard (box for transportation) (3) 6 books (4) small jars (5) marbles.

Place two stacks of books on the table, with a distance of about a dozen centimeters between the books (see Figure 32-1).

Place thin cardstock on top of two stacks of books to make it a bridge (see Figure 32-2).

Place an empty jar on the bridge and see if the bridge can hold the bottle. It is almost impossible (see Figure 32-3).

Now, remove the thin card and place the corrugated cardboard in place (see Figure 32-4). See if it can hold the bottle. It can.

Now, place a few marbles into the bottle (see Figure 32-5). Continue to increase the number of marbles to test the bridge. You'll find that a single piece of corrugated cardboard can hold more weight than 4 or 5 other thin cards stacked together.

Inspect the sides of the corrugated cardboard and notice that there are small triangles between the top and bottom of the cardboard. These small triangles form small brackets that resist the weight from above. Regular cards don't have these brackets.

Hehe. You're so nice.

Do you know how difficult it was for us to make paper bridges back then?

The material is only newspapers.

Paper bridge with a span of 30 cm and a width of 10 cm.

As a result, our paper bridge only bears 80kg of weight because it was stepped on by classmates, and the tragedy is that it did not leave **.

However, the model is still in high school.

When I went back to see it, I was satisfied.

The simple method of paper bridge is as follows:

Prepare materials: colored paper, utility knife, adhesive tape.

1. First fold the two pieces of paper in half, and then cut them with a utility knife.

2. After cutting, roll up the two sheets of paper separately, fix them with tape after rolling them up, and then take another piece of paper to cut them, and then roll them up to make 4 small sticks.

3. Take the other two pieces of paper, do not cut them, roll them up, fix them with tape, and make them into two small sticks that are a little longer.

4. Take another piece of paper and fold it in half, and then fold a small side on both sides.

5. Fold up the 4 short sticks, then clamp them on the long sticks, and then fix them with tape.

6. Fix the long stick to both sides of the paper strip in step 4.

7. Done. Steps of the process of making a paper bridge with compression.

1. First of all, prepare five sheets of paper and transparent tape, the length and width of the paper should be the same size, and two of them should be torn from the middle to make four sheets.

2. Roll up four smaller sheets of paper that have been torn and roll them up as tightly as possible.

3. Use two large pieces of paper to roll out two long strips, in fact, the same as the previous four strips, which are a little longer, and the same should be rolled a little tighter.

4. Fold a large piece of paper like a channel steel, and fold up one centimeter on both sides.

5. Fold the four strips in half, then clamp the folded strips on the strips, add two small ones to each strip, and then fix them with transparent tape.

6. Put two long strips of paper in parallel, and then put the channel steel-shaped origami on it as the bridge deck, and fix it with adhesive tape.

1. First measure the length of the place where the bridge is to be built, then calculate each piece of paper according to one-third of the length, calculate the number of paper sold in the bridge state that is needed, and then fold them one by one at one-sixth of the place, and then fold them in half on both sides of the wide section, and finally fold again, the more times you fold, the greater the weight you bear;

2. Roll the newspaper into 4 rolls, then connect the two rolls together, wrap them with paste and paper towels, paste the newspaper one by one, and after the paste is dry, the newspaper will become hard;

3. Fold the paper into a www shape, and then place it vertically, so that each strip supports each other;

4. Then cut out the palm-wide strip of paper, fold it several times in front and back to form several layers of thick strips, and then put the strip of paper upright and glue it into a honeycomb shape, and the bottom surface of the bridge is completed;

5. Fold the paper into a wavy shape, take out a piece of paper and fold it inward along a small part of the width, and then fold it in the opposite direction with the length equal to the width just now until the paper is folded, and then use the isosceles trapezoidal shape composed of three triangles as a bridge;

6. Recently, the structure of these completed bridges was glued together, and the paper bridge was completed.

1. Measure the length of the place where the bridge is to be built, then calculate the number of papers needed by one-third of the length of each piece of paper, and then fold them one by one at one-sixth, and then fold them in half on both sides of the wide section, and finally fold them positively and opposed, the more times you fold, the greater the weight you bear;

2. Roll the newspaper into 4 rolls, then connect the two rolls together, wrap them with paste and paper towels, paste the newspapers one by one, and after the paste is dry, the newspaper will become hard;

3. Fold the paper into a www shape, and then place it vertically, so that each strip supports each other;

4. Then cut the newspaper into palm-wide strips, fold them a few times in front and back to form several layers of thick strips of paper, and then put the strips of paper upright and glue them into a honeycomb shape, and the bottom surface of the bridge is completed;

5. Fold the paper into a wavy shape, take out a piece of paper and fold it inward along a small part of the width, and then fold it in the opposite direction with the length equal to the width just now until the paper is folded, and then use the isosceles trapezoidal shape composed of three triangles as a bridge;

6. Recently, the structure of these completed bridges was glued together, and the paper bridge was completed.

Here's how to do the paper bridge:

1. Fold the two sheets of paper in half and cut them with a utility knife.

2. Roll up the paper and flatten it separately, making a total of four.

3. Then roll up two larger sheets of paper in the same way, longer than before.

4. Yiyan rents a piece of paper to make the bridge deck, and folds a small side on both sides of the paper.

5. Fold up the previous four small sticks and clamp them on the strip and fix them with tape.

6. Then fix the combined stick on the bridge deck.

Benefits of Origami: Origami is not only an art, but also a method of exercise. "Origami is good for anyone, whether it's children, young people or the elderly.

Chen Chaoying, who is the president of the Paper Art Society, said, "Origami can exercise people's comprehensive coordination skills, including hands, eyes and brain. For example, learning origami requires looking at the folded process with your eyes, thinking while looking, and remembering the process.

First of all, prepare a dozen blank papers, and draw a bridge size map at the same time, so that the size of each part of the bridge can be made as a comparison and practicality during the later empty Huai period.

After the size of the bridge and the white paper are ready, roll the white paper into a paper tube, fold the two pier paper cards according to the creases, and stick the double-sided tape on the bucket Wang You to fix it into the shape of the pier. Take out the fixing cardboard, and fix the two folded piers at both ends of the cardboard to build a complete pier. Then cut the previously rolled paper tube into the same size as the design according to the clever design size, note:

At this time, it cannot be glued.

After the various departments of the bridge are cut, each part of the bridge is pasted together through glue and special connection methods to form a part of the bridge, and then another part is made in the same way to complete the main frame of the bridge.

By gluing the parts of the bridge together again, the entire paper bridge can be completely completed.
