Gripit 13mm Heavy Duty Plasterboard Fixing

GRIP IT FIXINGS TESTING 

Tests were carried out on all four types of Grip It fixiings using the following board:-

LARFARGE - GTEC standard board - Britsh Standard EN 520 : 2004 + A1 : 2009

Breaking Load N210 = 21.414kgs = 0.21kN

A single Plasterboard with a thickness of 12.5 mm

Objective:

The object of the tests are to establish the load or weight carrying capacity of each of the four types of "Grip It" cavity wall fixings, that have been specially designed and developed for attaching a range of components such as radiators, wall cupboards, flat screen television sets, shelf brackets and curtain rails etc to dry linings, cavity walls, hollow cavity walls and plasterboard ceiling applications

The carrying capacity for each of the fixings was determind by Tensile and Shear loading, plus canterlever loads.

Cantilever loads were measured at distances of 50mm, 75mm and 150mm from the vertical face of the plasterboard

Test Method:

A timber framework dimensionally representative of a domestic stud partition internal wall was erected and the 12.5mm plasterboard  was secured using drywall screws.

Each type of Grip It fixing was seperatly secured into the plasterboard by following the installation procedures as laid down by Grip It Fixings.

Using a specially designed test rig and digital weight monitor each Grip It type was subjected to the various tests of Shear, tensile and cantilever.  All readings were recorded in in Kilograms, Newtons and British pounds weight.

The Results:

Shear:

Grip It Type	Shear Max(lbs)	Shear Safe (lbs)	Shear Max (kgs)	Shear safe (kgs)
	220	110	100	50
	265	132	120	60
	353	176	160	80
	397	198	180	90

Tension:

Grip It Type	Tension Max(lbs)	Tension Safe (lbs)	Tension Max (kgs)	Tension safe (kgs)
	83	44	38	20
	85	44	39	20
	85	44	39	20
	85	44	39	20

Cantilevered Loads:

Grip It Type	Cantilevered Max (lbs) at			Cantilevered Safe (lbs) at			Cantilevered Max (kgs) at			Cantilevered Safe (kgs) at
	50mm	75mm	150mm	50mm	75mm	150mm	50mm	75mm	150mm	50mm	75mm	150mm
	154	132	79	77	66	39	70	60	36	35	30	18
	110	136	50	55	68	26	50	62	23	25	31	12
	145	154	105	72	77	52	66	70	48	33	35	24
	134	88	110	66	44	55	61	40	50	30	20	25

Observations:

During the testing procedures no Grip It fixing failed the failure in all the test cases was the plasterboard.

It can be seen from the test results that the Grit It fixings when compared with other types of plasterboard wall fixings have a greater and safer load carrying capacities.
