Make a bridge pier out of paper What kind of shape can bear the maximum load

The practice of paper bridge bearing is as follows: 1. Use paper rolls and small paper sticks; Second, to design the appearance of the paper bridge; 3. Paper bridge production.

1. Roll a small paper stick with paper.

First of all, prepare some materials for making paper slips, such as glue, white paper, and knives. First of all, take out the white paper, roll it into a small paper stick, you can prepare a relatively small stick, and then take the white paper to roll on the stick, and then take out the small stick when it is about the same, and then use glue to fix the rolled small paper bag, to ensure that the small paper bag is rolled up is relatively strong, because the stronger the paper bag will be better in terms of load-bearing, generally roll about twenty-five pieces of paper can be used to build the strip of paper.

2. Design the shape of the paper bridge.

Before the construction of the paper bridge, it is necessary to design the paper bridge that you want to make, such as how to place the small paper sticks, what the piers of the paper bridge can look like, what the bridge deck should look like, etc., all of which must be designed in advance, so that you can have a spectrum in mind when making it.

3. Paper bridge production.

Take out the double-sided tape first.

Take out four paper sticks again, then take out two of them and put them on both sides to build a bridge deck, then use two to connect, reinforce the bridge deck, and then take out eight paper sticks, use them as the bridge piers of the paper strips, after the bridge piers are done, you can do the support points that connect the bridge deck, you can take out six paper sticks to make the support points, the small paper sticks of the support can be folded into the shape of W, the load-bearing effect will be better, and finally use five small paper sticks to stabilize the bridge deck, And use double-sided tape to paste it, so that a load-bearing paper bridge is made.

The practice of maximizing the load bearing of paper bridges: the basic principle of graphic load bearing is used to disperse or indirectly counteract external pressures, so that the weight is carried the most.

Drawing: To make a good paper bridge, you must start by making precise drawings as a guide. Drawings can be drawn in CAD, and finite elements can be used for force analysis if possible.

Making a honeycomb tube: Tools: Scrape a pencil (hexagonal wrench), hair dryer, white glue, production process:

Wrap the paper strip around the pencil, be sure to press out the edges and corners by hand when winding the first circle, glue a layer on each roll, glue must be uniform and appropriate, roll out the clear edges and corners with a smooth pen after rolling, and can squeeze out excess glue! After making a certain amount of honeycomb tubes, dry them with hot air in time.

Meaning:

The bridge deck paper is folded into an M-shaped cross-section, which is equivalent to the shape of a double channel steel. When the style of the bridge is an arch bridge, first measure the length of the place where the bridge is to be built, then calculate each newspaper according to the length of 2 3, calculate the number of newspapers needed (at the bottom), and then fold one by one at 1 6, and then fold the two sides of the wide section in half (one-third of each side is folded in half with each other), and finally fold in half (plus and con), fold from the far left side of the width, the more times you fold, the heavier it can bear), if there are more, use the same principle to make one more bridge to build on it.

Kiss! Hello, happy to answer your <>

The method of achieving the maximum load-bearing of the paper bridge is as follows: 1. Roll the white paper into multiple paper sticks with heart, and use glue to stick the paper into a stick shape, and then roll the white paper into multiple paper sticks, pay attention to the stronger the paper sticks, the better the weighing. 2. Roll the white paper into multiple paper sticks and roll it to a certain amount.

After reaching a certain number of paper sticks, you can build a paper bridge, pay attention to the design of the paper bridge in advance, and measure the size. 3. First use double-sided tape to connect the two strips of paper on both sides of the bridge deck, a total of four strips of paper, and then use eight strips of paper as the bridge columns, six strips of paper as the support point of the bridge connection point deck and 5 paper sticks The paper sticks of the bridge deck are glued with double-sided tape. 1. Flat paper bridge.

Flat paper bridges are the simplest bridge designs. It consists of a single sheet of paper placed on two cups. The distance between the two glasses should not be too far so as not to put the coin on the paper.

Once the paper is in place, start adding coins, one coin at a time. You will find that you can only put one coin on the flat paper, and when you put the second coin, the bridge will cross the bridge, so this kind of paper bridge is less stable. 2. Arched paper bridge.

Roll the paper so that it arches in the middle and place it on top of both cups. The same two cups should not be too far apart, otherwise the coins on the paper will not be able to support each other. The distance between the two cups should be the same as in the flat paper bridge experiment compared to the flat paper bridge.

The paper is in place at the rear wheel and begins to place the coins in the center of the bridge, which can hold multiple coins. When a certain number of coins are reached, the bridge falls into the space between the two cups. Hope mine can help you <>

Do you have any other questions?

The principle is to use various cones, triangles, cylinders and some good load-bearing figures on the bridge to disperse or indirectly offset the external pressure.

1. Paper bridge, as the name suggests, is a bridge made of paper, which has a particularly high scientific and technological content, knowledge density and understanding of the performance of materials. 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.

2. In the process of applying pressure, the failure style of the bridge is various, including compression failure of structural points, tensile failure of paper tape, bending failure of rods and other damages. From the size of the load-bearing, it can be seen whether a structural form is reasonable and whether the coordination of various components of the bridge is in place. The small paper bridge can bear hundreds of kilograms, reflecting the perfect combination of structure and mechanics.

Extended information: Directly transmit the self-weight and various external forces to the main structural components and their connecting joints of the foundation, including load-bearing walls, poles, frame columns, piers, floor slabs, beams, roof trusses, suspension cables, etc.

Masonry structure (brick-concrete structure), frame structure, shear wall structure, frame shear wall structure, frame core tube structure, tube in tube structure, frame support structure (frame-supported shear wall structure and frame-supported masonry structure), special-shaped column frame structure, short limb shear wall structure, plate column structure, light steel structure, heavy steel structure, wood structure.

Slab staircase: It is composed of horizontal ladder beams, ladder columns, ladder plates, and platform plates.

Beam structure: It is composed of 2 oblique ladder beams, 2 horizontal ladder beams, ladder columns and ladder plates.

The main difference in the section is that the beam staircase should draw an oblique ladder beam, and the ladder plate of the plate staircase is only a 100-140 thick ladder plate.
