Building Materials and Construction Technology
Du och 19till: A telephone pole holds a couple of swings. Now it's getting harder to find.
fredrik.johansson: To calculate the angles in a triangle, you need to know the lengths of at least two of the sides. By forming a right triangle with the slanted part as the hypotenuse and the distance between the verticals as one of the legs, you can calculate the angles using basic trigonometry.
Anonymiserad 405730: [citat] Yes, it's good but small pieces of wood or plywood strips are enough depending on what you have.
cpalm: Skip the house fix, it's basically just an extremely expensive cement mortar. I think regular render mortar C is the right choice in this context, but if you absolutely necessarily want a mortar with good adhesion that's easy to "spread," then gypsum mortar is a better choice than house fix.
pacman42: By the way, how long should one wait before laying new plastic on top? I'm thinking it should dry for a week maybe, the slab is still damp from underneath...
Installation: [citat] A blower door that most serious users use. 50Pa is the minimum requirement. They usually turn it up higher, around 65-70 as well.
el_palpo: From the strength of materials, it is learned that beams should be spliced 1/4 to 1/3 of the span from the support. This is because the moment forces are low but the shear forces are high at that point. A nail plate is good at handling shear forces but not moment forces. Directly over the support, the shear forces are low but the moment forces are high, therefore it is less suitable to splice
cederbusch: Sorry, a bit click-baity headline. But the question is whether I should reinforce the load-bearing parts of my walls? You see the picture. The roof is supported by 2 nailed together 28x58 (type) at a distance of 1220. At least in the part I have opened. Then there are slats in between to form compartments that were filled with wood shavings. Or well, they probably were in the 50s. Now 1/3 of the
cogline: Hello. I am in the process of renovating an old barn to better utilize the space. The ceiling height inside is way too low, so I need to raise the floor structure by about 50cm. I have seen and read several threads about similar renovations but need a construction drawing to get a building permit as it will be a structural change. Does anyone have any tips on a designer who "likes" old barn
Hep: There is a rather famous chimney, we occasionally get to see. It's time @Hybro Bring it out.
BWall: [citat] But we have a gap between the cement floor and walls with plastic spacers. Nowhere does wood touch concrete. The air gap is ventilated with the help of a fan that draws air from the basement into the air gap and blows it out through a vent.
BirgitS: What might be present specifically on garage and boiler room walls are asbestos cement panels on the outside of the concrete. This is for fire safety reasons. But you can tell if there are panels.
gdsn00b: [citat] Can you screw directly into the chemical anchor afterward? Or how does it work? Do you just spray it straight into the hole and let it cure or?
Karl-Ove Qvarfordt: According to the top image, I am assembling.
Bjober: The fact that it has rotted is proof that it has been too moist. Rotten wood also absorbs even more water more easily, becoming like a sponge. This exposes other wood further into the construction to more moisture and the risk of fungal attacks. If you don't want/can't replace the entire board, cut out the damaged part and splice in new. Better ugly than dangerous. And try to keep the moisture
Vintersnö: [citat] Ok, what a shame! That's what I suspected, that they have an important function. I'll have to figure out how to solve this so it looks nicer but maintains stability. Thanks for the help🙏🏾
magnuslink: [citat] I am going to do the same thing and am also curious if someone has done the same and it turned out well?
Lilllen: [citat] The original poster will not answer you, as they no longer have their profile. They may have gotten a new one and happened to see this, but probably not. However, I think you can still get help. Have you also had craftsmen? Then a crack and hollow sound?
13th Marine: Here we place a swimming dock every year: [bild] Based on burton pipes and stands for 5 months in salt water every year. The pipes and such hold up well, the connections rust a bit, so we usually have to replace one every year, but that's mainly because we keep assembling and disassembling the whole thing.
nybbstrom: I have installed drywall on the ceiling and taped the joints with paper tape. In one spot, the tape came loose when I painted the first coat of paint and it won't go back. There was probably not enough joint compound under the tape. Is there anything I can do to fix it? I'm tempted to make a cut in the bulge that sticks out and try to smooth it out again somehow. Any tips? The area is about
Lars-Göran Lindström: [citat] Not in wood. What has been delivered are concrete plugs and corresponding "screw". (Hardly ever)
tobohl: Thank you, it's joint tape that was missing. Clumsy, one might say. thanks for the reply
Manganbangan: A turnbuckle on each side. Attach it to the post and then to the wood.
