hi what would happen if you apply tile adhesive directly to hollow block walls without applying mortar first? can the 1 inch thick tile adhesive function as the 1 inch mortar already?
Ok. The malleable shield that expands is very well noted. But what would happen if the hollow portion are filled with non-shrink grout? Then it's like you have the entire bolt embedded in concrete with the tip hold by malleable shield. But then in dynabolts like the following. The expansion...
Oh, by the way I drew that graphic using photoshop. I was showing that there was no contact on the upper part.. just the bottom part. I was wondering how its tension breakout and shear breakout differs to that of dynabolts in which only the bottom part expands.. dynabolts have same effect of...
When the bolt is inserted, the housing opens inside concrete that secures it in place. Is the mode of failure you envision breakage of the bolt itself (yielding at 36 ksi) or slip from the housing? but note in anchor bolts.. it is the concrete that is the limitation because it breaks before the...
How would this lag expansion bolt perform when they are used in base plate anchoring...
It looks like this:
When installed under base plate:
When you use 16mm lag screw, the housing that needs to get inside or drilled must be 22mm.. so when you insert the housing inside, there is a gap...
I think Hardieflex has the thoughts that hot rolled steel has different properties to cold rolled steel.. but then googling. I found out they indeed do! Here:

Alloy 1018 is the most commonly available of the cold-rolled...
Steel is steel.. but for the same diameter say 3/8" rebar, there are grade 40 and grade 60. Likewise the impression they are giving is that cold rolled steel are like grade 40.. hard rolled steel are like grade 60.. they are same diameter but the grade or compressive strength may differ.. what...
I think you can recognize between hot and cold rolled steel.. the following site says cold rolled still are smooth grey while hot rolled steel are bluish-grey..
Why does Cold Finished Steel have a smooth grey finish, while Hot Rolled Steel has a rough, blue-grey finish...
hokie.. the philosophy in seismic design is ductility and not brittle failure.. in the event of earthquakes.. the Hardiflex must not break apart and fall down.. instead the fasteners or studs inside it is the one that must move.. isn't this what you mentioned too..
when we think of hardiflex...
In the same url shared in the first message. It was mentioned
"Steel framing members must be fabricated from light-gauge sheet steel 0.55mm thick minimum to 1.6mm maximum. If heavier sections are used difficulties may be experienced in fixing the
self-drilling, self-tapping fasteners. Refer to...
The following is the recommended pattern for the nailing...
With so much nails.. won't it crack during seismic movement if they are attached directly to hot rolled 1.6mm C-section?
The C-section is 2x4 inch and 0.063" (1.6mm thickness). The 9mm hardiflex were supposed to be connected to the...
The company i bought the 1.6mm cee purlins said they were hot rolled. I need to know. If purlins are 1.6mm hot rolled vs cold rolled. Do they have similar hardness or stiffness or is the hot rolled harder or stiffer than the cold rolled (but same thickness)??
C-purlins are not wide flange or tube, they are not strictly HSS (Hollow Structural Sections).. how do you compute for the buckling of C-purlins.. what is the common formulas used?
I know C-purlins can buckle and so can't officially take vertical loads.. but I'm wondering how to compute for it's buckling and the axial load the top of it (2 meters vertical height) can theoretically take.. assume the purlin is 2 inches by 4 inches in size and 0.07" thick (1.8mm).. would it...
Up to what thickness are purlins cold formed? Are there no 1.6mm purlins that is hot formed? how about 2mm or 1.8mm because the delivery has mixture of 2mm and below?
Oh no. I have dozens of 9mm thick Hardiflex cement boards at site ready to be installed to 1.6mm thick purlins. The web site shared earlier was about sidings and eaves.. it's in page 11. But in the general Hardiflex frame installation guide...
