Steps for making a paper bridge 100, steps for making a paper bridge

I make the bottom type tension state. (The tensile performance of paper is better). The compressed part is made of paper rod structure.

The most important attention is paid to the lateral stability of the bridge. It is better to connect with an oblique rod.

Roll the paper into a thin roll first, and roll it tightly. The pressure that this roll can withstand is not very large, and the longer it is, the less pressure it can withstand, and the easier it is to be crushed. However, the tensile force that the rolls can withstand is very large, and they are adjusting the structure to turn all these rolls into tensile members.

When pressure is necessary, they cut the paper roll shorter and use many thin paper rolls to bear the pressure together in this pressure area.

Fold 2 sheets of paper in half and break them into 3 pieces. That's it.

Making paper bridges Ingredients: ruler, pencil, cardboard, watercolor pen, scissors, glue (double-sided tape is recommended).

Production steps: 1 Take a piece of cardboard and draw a sketch of the bridge (including the bridge body, bridge deck, and pier abutment) with a pencil and ruler 2 Make the bridge body, bridge deck, and pier according to the sketch.

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

2. Roll up and flatten with paper, a total of four need to be made, 3. Then roll up two larger sheets of paper in the same way, the length is longer than before;

4. Make a bridge deck with a piece of paper, and fold a small side on both sides of the paper;

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

6. Fix the combined stick on the bridge deck again;

7. The last paper bridge is done;

Method steps.

1 7 Prepare paper and transparent tape.

2 7 Roll up the paper (four short and two long).

3 7 Fold a few short ones in half.

5 7 The rest of the poles were likewise treated, fixed, and served as the foundation pillars of the bridge.

6 7 in taking a piece of paper, fold it into the appropriate width. Acts as a bridge deck.

7 7 Then paste the bridge deck on the bridge body to make a paper bridge.

Each sheet of paper is first reinforced with glue (all of which is coated and then air-dried), and then rolled into paper rolls and then staggered with glue.

You should try to make the paper thicker as much as possible, and after sticking it, wait for the glue to solidify, and then apply it again, and it is estimated that ten Zhang Zhimin will not collapse.

To prevent various accidents that may occur.

1. First fold the origami in half and fold out the obvious middle line.

2. Pinch out parallel folds perpendicular to the middle line of the origami.

3. Fold both sides of the origami inward.

4. After the inner folding is completed, bend the inside of the folding box.

5. In this way, the paper bridge is completed.

Paper bridges, as the name suggests, are bridges made of paper, in which the scientific and technological content, knowledge density and understanding of the properties of materials are particularly high.

The paper bridge has different forms, and the composite section is mostly used in the common paper bridge structure, and the shape is mostly triangular, rectangular, trapezoidal, arched, pawn and some other forms. Paper Bridges originated at the University of Manchester in the United Kingdom as a science and technology activity for the students of the university.

Prepare materials: several sheets of paper, transparent tape.

<>4. The rest of the roots are also treated, fixed and sold only to live, and serve as the foundation pillar of the bridge.

5. Take another piece of paper and fold it into an appropriate width. Acts as a bridge deck.

6. Then paste the bridge deck on the bridge shirt, and a paper bridge is completed.

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

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

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

4. Make a bridge deck with a piece of paper, and fold a small side on both sides of the paper;

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

6. Fix the combined stick on the bridge deck again;

7. The last paper bridge is ready, as shown in the figure below

The practice of the paper bridge of general technical works in the second year of high school is as follows:

Tools Raw materials: paper, scotch tape. Method steps.

1. Prepare paper and scotch tape.

2. Roll up the paper and roll it into a paper tube, four long and two short.

3. Fold the short paper tube in half.

4. Fix the folded paper tube on top of the long paper tube.

5. The remaining ones are treated in the same way and act as the foundation pillars of the bridge.

6. Take another piece of paper and fold it to the appropriate width to act as the bridge deck.

7. Summoning Huai Zen and then pasting the bridge deck on the bridge body, a paper bridge was made.

First method:

1. Cut the carton according to the black line, and combine the cut parts with tape.

2. Make bridge holes with hair roots and colored paper.

The second method:

1. Cut the carton according to the pattern.

2. Paste the two sides of the bridge and the bottom of the bridge.

3. Cut a long strip as wide and dusty as the bottom of the bridge, and the length should be enough to cover the bridge deck.

4. Combination, completion.

Paper bridge method: through part of the cross-section 60 * 280, the minimum span of the bridge needs to reach more than 280. The size of an A4 sheet of paper is 297*210, and if a plate bridge is used, a column needs to be set in the middle.

It is difficult to meet the requirements of seepage cracking. Preliminary consideration is to deal with the use of arch closed bridges.

Please click Enter a description.

2.Determine the size of the arch and leave 10 safe passage space outside the object size. Finally, the arch height was determined to be 115.

3.Other dimensions are determined accordingly.

4.Once the dimensions were determined, the structural form of the bridge was considered.

Do your own research on the structure of the wooden covered bridge and the structural form of the Leonardo da Vinci Bridge.

5.For A4 paper, you need to circle it or fold it in half repeatedly.

We know all kinds of bridges, have you ever seen a bridge made of paper? Today I will teach you how to DIY paper bridges.

Tools Materials

nbsp;A4 paper, double-sided tape, scissors, pencil, ruler.

How it works:

On A4 paper, draw a trapezoid, which can refer to the dimensions in the figure.

Crop and fold according to the drawing pattern, the straight line is the part that needs to be cut, and the dotted line is the part that needs to be folded.

<> Glue the double-sided tape to the location shown in the red box.

<> according to the creases, the trapezoidal paper is made into the piers.

<> fold two sheets of A4 paper in half and cut them, paste them together to make a base.

Glue the pier that has been pasted in step 4 to the red base.

Cut the A4 paper into two equal rectangular wide strips of paper as the bridge deck, the width of the strips of paper is the same as the width of the pier, and the two wide strips of paper are stacked together as the bridge deck, and the strips of paper do not need to be glued together.

According to steps 1-4, make another pier and stick it to the base, pay attention to the distance between the two piers is not too large, and cannot be greater than the length of the paper bridge deck.

Put the above red wide paper on top of the two piers as the bridge deck, and the paper bridge is built.
