One of the strategies of DIY party in home decoration: to climb the wall at home.

Several roommates urged me to ask for a DIY strategy to climb the wall, so I asked my husband to write one.

Science and engineering men like to break up drawings and data when writing. Let's make do with it. Some parts can be skipped automatically. Anyway, I can't read it. Ha ha ha!

Write a strategy of DIY aluminum alloy frame+vitrified brick cabinet.

Looking at this process now, I feel very laborious. DIY party in home decoration is a masochistic party asking for trouble!

All the efforts are for being blown out. NB? -Homemade climbing wall's notes?

It has been 16 or 17 years since I started to get in touch with rock climbing in college. I can really be regarded as an old rock friend, but the word "persistence" is missing from the dictionary. Three days of fishing are basically drying nets, and the level is really unsightly. Up to now, it is only an entry-level melon. However, to say whether I like it or really like it, there is a person in the mahjong circle who is called "addicted and poor in skills", and it is absolutely appropriate to evaluate me. It happened that the new home was renovated last autumn, and the sun room had two walls. I didn't know what to do, so an idea of Feng Kuang came out: both walls were 3 meters wide and 2.6 meters high, just enough to make a small climbing wall. At home, Dabao is over three years old and full of energy. Bauer also makes various noises in his mother's stomach (now he is almost one year old). There is a climbing wall where children can play, and I can catch the light (obviously I want to play, too), and laugh when I think about it! ?

With an idea, it is natural to study the market situation. I found a professional wall climbing merchant on the Internet to make an inquiry, and the result almost scared me: a simple shapeless wall costs 20 thousand yuan! If I add shapes like inclined walls according to my idea, the two walls will advance to more than 50 thousand in minutes!

What is my decoration budget? It is unacceptable! As a science and engineering man with the strongest practical ability in the financial industry, carpentry is even more important, so I told my wife a heart (Yi), a heart (Stone) and a heart (Chong) and asked my brother to make one for you! Daughter-in-law has long been used to screwing with me and is too lazy to take care of it. She put her children on the ground, so I can walk around. ?

First, an armchair strategist?

Do it. Let's see if there are any experts on the internet who have homemade wall climbing tutorials. Although the information is pitiful, only two or three articles can be found for reference, but fortunately, the core materials, basic processes and precautions are clearly defined. If you are interested, you can refer to build your own indoor climbing wall (/viewnews-15970-page-1.html).

At the same time, in order to observe and learn the methods of making professional rock slabs more accurately, I also dug deep into the works of several professional manufacturers, and repeatedly observed and compared several photos of climbing wall's internal structure as a knowledge reserve. ? With the basic knowledge reserve, I crouched under two walls and conceived a big plan. After overthrowing N ideas, the big outline basically took shape: the wall on the left was made into a straight wall, with no shape along the wall, and the wall on the right wrapped the air conditioner and made into a diamond.

It is recommended to design an artifact here: Visio software under MS Office, which has a friendly interface and is easy to use. Very suitable for simple home and engineering design. Based on precisely measured data, the concept map is quickly formed:?

Don't you get it? A paper model:?

The conceptual design is finalized, followed by the construction scheme and safety calculation. For the sake of safety and convenient operation, I plan to combine steel frame and wooden frame, in which the diamond shape of the right wall needs to be fixed on the sunny roof with a steel frame in the shape of a machine gun, and the outermost fixed point (the red circle in the picture below) bears the greatest force, which directly determines the safety of climbing the wall. ?

How to fix it? Everything has to speak with data. ?

(This Duan Chun calculation can be skipped if you are not interested.) For the sake of strength, I choose a multilayer board with a thickness of 1.5cm and a weight of about 15KG/ m2. The area of the rock slab on the right wall is about 7 m2, and the weight is temporarily taken as105 kg. About 150 fulcrums need to be installed on the right wall, with a total weight of about 50KG；; The weight of steel frame and wooden frame is temporarily 30KG, and the total weight is 185KG. Plus an adult and a child, the total weight is calculated at 300KG. For the convenience of construction, I intend to fix it with carbon steel drill tail screws. Upon inquiry, the shear bearing capacity of ordinary carbon steel screws with a diameter of 4.2mm is about 0.9KN, that is, the maximum static lateral bearing capacity is about 90KG. If all the 300KG weights are hung on a fixed point, at least 4 screws are needed. Considering the leverage of the wall pull point and the ground support, the bearing capacity of the top fixed point should not exceed 100KG. I put six screws on the rightmost fixing point, regardless of the tension of other fixing points and side walls, and the safety margin is more than five times. This is appropriate! ?

The feasibility of the scheme is passed, and then the overall detailed construction design should be done. However, the more detailed, the more amazing the workload. You can only do it one day a week, and you are not allowed to go to the Year of the Monkey? During the period, I was also upset because of various other things, and once wanted to give up. However, NB has been blown out, and the trouble is small and the teeth are hard! ?

Second, integrate theory with practice?

After the theoretical work is completed, it officially enters the practical operation stage. If you want to do a good job, you must sharpen your knife and buy electric tools for work in advance.

Of course, the production sequence is from the inside out, starting with the steel frame. I was lying on the scene, measuring and drawing. It took me half a day to finally determine more than 20 angle steel parts. Running to the building materials market with drawings, the master selling steel almost popped his eyes out. What a strange group of ghosts! ?

I didn't trust the master, so I made an appointment to come early in the morning and start cutting and welding under my personal supervision. After making the steel frame, I went to the tool shop to rent an electric hammer (that is, a high-power electric drill), suddenly punched bolt holes and fixed the steel frame and wooden frame on the wall. Forty or fifty holes in two walls, all the way down, really dizzy and tinnitus, hands numb, heart panic. Drill holes, screw bolts, and screw steel frames to the wall one by one, except for hand acid. ?

Twist the steel frame into a wooden frame, and then go to the building materials market to buy wooden squares. According to the planning scheme, the two bundles of wood were cut into required lengths one by one, then drilled and installed, and the woodworking mode was started, so time passed quietly. Finally, one day, the wooden frame was finished:

Looking at the picture, we can find that the actual construction results are different from the drawings. This is also normal. The plan is doomed to be destroyed ... and many details have to be arranged on the spot as needed. Let's feel it at the two most chaotic nodes.

When the framework is completed, the next step is the panel. According to the actual size of the wooden frame, the drawings are still a group of ghosts without duplicate samples! ?

The wall on the left is ok:

There are too many walls on the right;

Taobao found a merchant selling E0 environmental protection multi-layer board of Millennium ship, and it can add money to help cut the board, which can save a big event. A joinery board is one meter two by two meters four, which will be seriously wasted if it is not planned well. After some puzzles, the cutting map is formed.

Although it is still chaotic, at least the factory that cuts materials can do it. When the sheets are pulled back, chamfering and trimming are needed according to the joints between the sheets. Woodworking mode is full of firepower, which is endless work. The power tools bought in advance give full play to their functions, benefiting from the productivity leap brought by technology! ?

Third, often take a walk by the river?

Finally installed on the last few panels, it feels great ... not good! The big board is not the right size, and it is so narrow, WTF! Patching is unrealistic, so I can't help it. I can only find a supplier to replenish it. Week after week, time and money are lost. Semi-finished projects can only be left hanging, angry and rested! ?

Replenishment in place to continue construction. However, life is always full of surprises. Seeing that the staged victory is in sight, there is another situation: the finger arbitrarily confesses to the violent chainsaw and is rejected (sawed). Here I offer my delicate hands, bloody and high-energy warning ahead, please skip the picture below if you are timid:

Actually, is it okay? Anyone who hurts anyone knows anyway. Here, I solemnly remind the majority of hands-on enthusiasts that although power tools are efficient, they are also cruel and cautious! Watch out! Watch out! ?

Fourth, from lining to face?

After playing the last few boards with injuries, it will be the New Year. Take a rest after the Chinese New Year, and the finger injury is almost good. Continue to work and open a rock tip installation hole for the board. There is no accurate number of hole spacing, and some even poke at will according to mood. The drill bit turned very vigorously, poking 370 holes in more than two hours, fearing that the patient would be cautious.

After the hole is poked out, you have to take off the board piece by piece and knock in the four-claw nut. Fortunately, I left a heart before, and only screwed screws in all corners of the board as temporary fixation. ? The four-claw nut is ingeniously designed, and it is very firm after being smashed into the board. The father-in-law also helped swing the hammer and had a good time! Men are teenagers until they die, oh yeah! )?

It takes a lot of effort to knock down the small 400 screw. When they were knocked down, they were hung back to their original place. Each board is tightened with a circle of screws to ensure that it is firmly combined with the frame, and safety comes first! ?

After the foundation is completed, the surface should be decorated and beautified. The old father-in-law said that you can get some stickers and make it into an underwater world. How beautiful! After the imperial edict, I turned to the omnipotent Taobao, bought thick self-adhesive PVC wallpaper with fish-shaped stickers, and the abstract underwater world was freshly baked. Sticking is too messy, straight men have no aesthetics, please be merciful, cough ...?

Five or half a hundred miles?

Finally, the rock points were installed, and the bolts were tightened one by one. The progress was surprisingly slow. Think about it, too. Although only 250 rock spots were bought, each one had to be twisted for a few minutes, and the dispersion of color, size and shape had to be considered in a daze, which was quite time-consuming. The large hexagon wrench used to screw bolts is a small iron bar with a blunt root. It's a super wrench. It hurts to lose your temper hundreds of times! After three afternoons, climbing the wall finally completed the task.

Finally, I have to talk about pads. Due to the irregular shape of the venue, the initial idea was to find a sofa factory to make three or four large sponge pads with suitable shapes and put them together. However, the customized cushion is not low in price, single in function and inconvenient to store. After thinking about it, is it appropriate to buy ready-made folding cushions? Taobao found a sports mat manufacturer with a good reputation, bought six hard mats and six soft mats, and piled them in irregular positions just to cover all the floors that might fall. Although it can't achieve the cushioning effect of air cushion or trampoline, it is not a problem to cushion the vibration and avoid injury. After all, the total height is only 2.6 meters. 30% folding mats are all stacked in the corner or stand on the wall, which does not take up much space. You can also cover the sun room on the first floor and let the baby roll in it. ?

Later, I discovered a new use of mat: building a house. The following is the apartment with two bedrooms and one living room:

Finally, let's calculate an account: in terms of time, it takes more than half a year to go back and forth to work, mainly on weekends, and the effective working time is about twenty or thirty days? Anyway, it is much slower than the professional team. In terms of funds, 500 yuan, an electric tool; Steel frame 900 yuan; I can't remember, probably 400 yuan; 300 yuan (bought a lot more) for hardware such as screws and drills; Multilayer board 1 1 piece plus freight and processing fee of 2000 yuan; Rock tip, four-claw nut and bolt 1700 yuan; Cushion12,2500 yuan.

The above amounts to 8300 yuan.

Plus medical expenses and personal working hours (useless workers! None of them are useful! ) ... in your dreams. I can't count. ?

The last few real climbing effects:

Finally, I want to say: I am a DIY party in home improvement, and I am proud! ?
