throughbolts into poor breeze block

[BrokenBiker]

have a dilema...i absolutely must have something fitted to one of my house walls (on the inside) today

i would have had it done sooner but have had an issue with the item so the replacement is coming today.

i am using 12x180mm rawl through bolts because i have used them for a similar application before and i had some left over from then.

i have dot and dab plaster board on top of breeze block and then red brick facing on the outer side. i usually use a blunt knackered HSS bit to break through the board and find the depth of the gap (on average about 20mm in this house) so i can set a depth stop on my SDS drill, however when going through with the hss bit, no hammer action either, it sank straight into the breeze block to a total depth of 130mm...the block turned to dust and i honestly didnt realise it was going into the block it was that effortless to drill in, i first thought i had hit a cavity or a missing block...

anyway, cut a small square out of the board for a better look, even drilled another hole to confirm the block was weak and it the bit went in as before, no hammer just fell in...

i am left with a clean and round hole, its on size and depth is good, however when i hammer the bolt in and then try to tighten it, it just pulls the bolt back out without it gripping at all...

need suggestions on how i can get 4 bolts in and tight before tomorrow morning as i have someone coming to check the installation and it has to pass.

this is what im left with after the 2 test holes, both 12mm and the bolts needed tapping in to get them to depth, but just pulled straight back out without gripping when the nut was tightened

Epoxy?

havent got any and havent got the car to go and get some either. i have been looking for my last tube of it but all i can find is grip fill and i doubt that would do...

im not sure if this is just a dodgy block as the previous bolts were put in about 3 foot below these and i had to use my sds drill with some hard bits and the bolts gripped nice and strong...

im wondering if drilling and 11.5mm hole instead of a 12mm might do it...the actual holes are going to all hit different blocks to this one but i only have one chance with it so if i screw the first set of holes up i have an even bigger problem

What about the expanding "butterfly" fixings?
The type that you push through to the back of the block and they spring open once clear of the block.
They have a fairly large surface area to pull on, you'll probably need to put some filler into the gap between the plaster board and wall though to stop the plaster board from being crushed, that's depending on weight of the items being fixed.

Don't know what you are hanging weight wise but would woodscrews hold? you could then hammer some timber plugs (coated in grip fill) into the holes, that's how they used to fit banister brackets and they took a fair bit of pulling in their life.

 

[rikrobson]

make some dowels to interference fit into the holes and then screw into the wood

Steve's spot on about the wooden plugs. They used to use them everywhere before plastic plugs and they take a fair old load if you get them in right.

Weight isnt the issue it is strength. It has to be fixed into the fabric of the building and will be grabbed and pulled about to make sure it don't move at all. The guy doing the inspection will be looking to see what fixings have been used too and he won't be happy with wood screws. Has to have substantial bolts fitted into an exterior wall.

Gun cabinet?

Seriously the amount of gyp they'll take is impressive. Definitely (assuming you have good sized screws) suitable for a miserable FLO to kick.

Any coachbolts?, they would screw into the wood and look right I am sure

I have the exact same walls in my bungalow and I use these and they have been great.

Go buy some chemset and threaded rod and be done with it.

Both my cabinets were fixed with woodscrews and passed without any problems.

My gun cabinet was and they denied it instantly on sight, he didn't even shake it about just said it wasn't suitable and walked out. The same guy is coming tomorrow...

I couldnt go out even if I wanted to as I was waiting for the safe to arrive, however they have provided fixings this time and good ones at that. Coach bolts and plugs... I drilled an undersized hole, tapped the plugs in and the bolts have snugged up nicely.

Bit of good fortune for a change as the last time I bought from these guys they didt send fixings at all

So is that you sorted then Dean?

They really are a miserable lot. There is absolutely nowt wrong with the method described and it's held up things to far heavier abuse than a damn cabinet! Still, it's your FLO so you're at their mercy.

Good luck!

coach screws into the wood in the wall

Who is Dean?

yes sorted now, i have just given it some abuse and it isnt budging. its only an ammo safe for rimfire rounds, its renewal time but i have also asked for another 2 calibres and they flagged that my current ammo safe is already at max capacity based on their random check about a year ago and its was rammed with ammo so they said either a bigger safe or an extra one, so extra one it was.

also had to put another cabinet in to keep the shotguns in to make space for the 2 new calibres (well they arent new but havent had them for a while, replaced them with others last time but need them back now lol)

the guy that comes to see me is an anti which really doesnt help, i dont know how he is in the position he is in when he opposes field sports. he is known for denying application and renewals for really daft reasons. a lot of his rejections are overturned but i havent got the time or motivation for a battle...i did request a different guy as my fathers application flew through without a hitch but apparently this guy is the only one available...

anyway, out lamping tonight so i can have a few things hanging when he turns up...gets him in and out a lot quicker and i am squeaky clean for this renewal now that this safe is in and solid...

ROFL could have sworn that was you BB! Looked back at your first post and I realise that's pretty far from your name lol

Glad you got it sorted man. How some of them get (or rather keep) the role is astonishing.

A (single) female friend of a friend was denied her license because "Women are irrational and without a man in the house to keep an eye on things she couldn't be trusted" - according to the FLO. Needless to say it was challenged and overturned but yeah, needless bloody hassle for everyone.

my father has had an SGC since last april and since buying his furst gun off me he took up clays and found a shooting partner. she didnt have a license but he would borrow a gun off me and lend her his gun...she applied and was granted but was told during her safety check that when she got her license, under no circumstance should she even think about buying a second hand shotgun as they are all very dangerous...first thing she did was buy my browning off me and i couldnt believe it when she said what he had told her

It is an utterly shameful attitude that you hope died out forty years ago but there's still some of them

How are they on mental health issues these days? Still think that everyone who's had a problem and got help will go on a rampage no doubt.

worryingly its a rather iffy subject...i know some lads that have been denied becasue they have had a bout of depression, but have been cleared by the doc but i also know a guy that i used to work with developed severe anger issues about 2 years into his first SGC, he was prescribed a few different pills, had to go to anger management classes, was taken to court twice after being arrested for assault and aggrevated assault and when it came to renewal time the officer conductiong the checks said that he was fine for a renewal as his docter had said, and i quote 'he doesnt see things or hear voices so im confident he isnt a danger'...

the man is a lunatic and its only a matter of time before he flips out and shoots someone, and thats coming from someone who likes him...

its like being policed by Gene Hunt sometimes
