This video will look at attaching timber to a concrete floor.īike pump (to remove the concrete dust from inside the hole after you've drilled it).Ī masonry drill bit suitable to the diameter size of your anchor. They are know by other names in other countries) are the ideal anchor for attaching almost anything to solid masonry such as concrete. DynaBolts (that's the name for this particular anchor in Australia.

added to that, shuttering strength, waterproofness, strength of supports of grade beam formworks, verticality of side shutters, and location of grade beam shall be checked as well.How to install concrete anchors.How to attach timber / wood to concrete or any other SOLID masonry surface using masonry anchors / DynaBolts. Lastly, after the completion of grade beam formwork, insure that designated grade beam dimensions are provided including sufficient reinforcement cover. These construction sequences are selected based on ease of construction and convenient. In this case, formwork can be fixed completely followed by reinforcement placement, or fix only the bottom shutter then place reinforcements, after that install side shutters. So, shutters shall be placed for bottom, and both sides of the grade beam.
If the grade beam is constructed above the ground, then the formwork construction would be similar to that of conventional beam. In this case, flat soling brick is formed along the grade beam instead of bottom shutter.Īfter that, either the reinforcement cage is placed on the flat soling brick before side shuttering is fixed or one side of the form is placed followed by installation of reinforcements. If the grade beam is constructed on the ground, then the bottom of the form shall be placed prior to its sides. Formwork installation for g rade beamĪfter the site preparation and excavation of trenches is completed, then forms will be placed according to the dimensions of the beam which shall be provided in the design drawings. 2: Grade beam excavated along with footings 2. However, excavation of trenches for the grade beam will be executed along that of footing when the grade beam is used with footings.įinally, if the grade is constructed above the ground surface, then installation of forms will be the first step in construction process of grade beam.įig. Where the grade beam is used between piles as shown in Fig.1, construction preparation and excavations will begin after finalizing pile construction. Alternatively, if the grade beam is constructed directly on the ground, then the ground surface will be leveled and prepared. Trenches for the grade beam is excavated Based on its level. Preparation and excavation for grade beam
In this article, construction process of reinforced concrete grade beam will be discussed. A continuous grade beam footing will transfer the load of a building to the ground or to its bearing points where their bases distribute the load to the soil. The grade beam either rests directly on the soil or above the soil spans between piles. They should be reinforced with continuous reinforcement that is developed within or beyond the supported column, or be anchored within the pile cap or footings as per ACI 318-14. Grade beams are commonly concrete beams which are designed to act as horizontal ties between footings or pile caps. Concrete Grade Beam Construction Process.
