I examined the merits and demerits of the construction method used to install steel frames in the distant past!
Hello, everyone. This is Enta. The other day, I found a pretty old concrete frame in the Kanto region and was checking it out (lol—like a suspicious person, lol). The distinctive feature of this construction method is that they start by spraying up to waist height. After that, they spray the upper part…
For formwork spray application, if the material inside the formwork is mortar, spray it at the same time!
Hello, everyone. This is Enta. Do you spray the formwork and the mortar inside the formwork separately? Or do you spray them together? How do you determine the finished shape? “Since they’re different types of work, you must do them separately, right!?” That’s a common topic of conversation. The finished shape is determined in advance when assembling the formwork…
How to Draw Slope Construction Drawings, Part 3
Hello, everyone. This is Enta. I meant “how to draw” a blueprint, not “how to write” one, right…? Japanese is tricky, isn’t it? I’ll be more careful from now on ^^ But anyway… This time, it’s “How to Draw a Blueprint, Part 3.” “How to Draw a Blueprint, Part 1,” “How to Draw a Blueprint, Part 2”—I’ve covered everything up to the title block…
How to Draw Slope Construction Drawings, Part 2
Hello, everyone. This is Enta. This time, we’ll cover “How to Draw Blueprints, Part 2.” In “How to Draw Slope Construction Blueprints, Part 1,” I drew the development drawing for now. I tried drawing a test blueprint (to make it easier to understand). Let’s say we have a slope like this. The slope frame is 300…
Proper Installation of Main Anchors
Hello, everyone. This is Enta. Things have started to get a little busy! It feels a bit overwhelming, but let’s tackle them one by one! But enough of that—when assembling the formwork, we install the main and auxiliary anchors…
I think it’s fine to do away with the use of trowels in spray-applied formwork work.
Hello, everyone. This is Enta. It’s already summer, isn’t it? Although the rainy season hasn’t officially ended yet. Here’s the projected end date for this year’s rainy season: Start and End of the Reiwa 6 Rainy Season (Preliminary Figures). There’s a chance of continued heavy rain, so let’s be careful out there ^^ But enough of that. Let’s talk about the legal framework. This…
The mortar inside the frames of a frame-type structure not only prevents weed growth but also helps prevent scouring and facilitates water flow for rapid drainage.
Hello, everyone. This is Enta. Last week, I went to check out a job site in Nagano. We’ve been working on this project for several years now, and the finished product really looks great. Even though it’s our own company, we’re doing a great job, lol. It’s a site along a river, and I can’t help but wonder, “Do we really need to do this here??”…
Here's how to calculate quantities for formwork in on-site spray-applied concrete construction.
Hello, everyone. This is Enta. You’re working on formwork construction, right? Do you know how to calculate the vegetation work and mortar spraying inside the formwork? The reason I’m bringing this up is that at a certain job site, there was a consultant doing something really unusual when it came to calculating the formwork dimensions. CAD…
Here are three ways to minimize waste during spraying!
Hello, everyone. This is Enta. It’s a real pollen hell because of the strong winds, lol. This is the time of year when goggles and masks are a must, lol. By the way, there’s quite a bit of waste during spraying, isn’t there? Do you know what that is? Even though the mortar was perfectly fine with no waste inside the sprayer, the material…
