Durable Floor with Beam and Block Floor

The concrete slab can be described as a smooth rectangular, reinforced concrete structure that can be cut to size in its length and width , however it is smaller in depth. It is also used in the construction of roofs, floors bridge decks, etc.

There are numerous designs that can be used for a slab suspended to improve the proportion of its strength and weight. In all cases, only the bottom surface is altered while the top is flat:

The concrete slab can be a prefabricated slab or an in-place one. Prefabricated slabs slabs are made in factories, and then transported to the location which is where they are lowered to the ground between concrete beams or steel. The slab could be pre-stressed in the manufacturing facility, and then post-stressed on the site , or end up being unstressed. The biggest drawback to this slabs is that if they’re not of the appropriate dimensions, it may not be suitable for. When it comes to in-place construction it is constructed on the ground of the structure using an enclosure into which the wet concrete mix is poured, referred to as formwork.

Rebar’s must be placed within the formwork prior to the concrete mixture is poured in them, in the event that they are to be reinforced. Once the concrete has set completely, and it is necessary to make sure it is completely sealed around this reinforcement plastic-tipped steel or bar chairs made of plastic are used to ensure that the rebar is separated from the foundation and sidewalls of the forms.

Formwork for a ground slab might only be able to have sidewalls which are that are pressed into the floor. the formwork for suspended slabs are formed in the form of a tray. It is supported until concrete sets, with the scaffold. Wooden planks , as well as boards, plastics or steel are typically used to build forms for. Steel and plastics are frequently employed in construction sites for business since they can reduce the cost of labor, however for sites with limited budgets such as for the construction of the concrete path for a garden wood planks are utilized since they are inexpensive.

In the 1960’s, I was involved in Post Tension concrete projects in the southeast United States for Noble Concrete, Inc. A large portion of our projects were the stressing of ring beams for dome concrete structures. Domes exert a significant lateral force upon the wall of structures that they rest. The ring beam keeps the walls back from falling because of the dome’s weight.

When it comes to concrete construction, there’s generally a significant safety element included with the help of steel bars. Post tension concrete can be different. Too much of something good can lead to problems.

The designer engineer will record on the drawings the tension needed and companies like Noble Concrete would bid on the work and then create the shop drawings that show the location and dimensions of the cables needed.

We were awarded the contract for the cathedral dome for a church in Jacksonville Florida and all was going smoothly. After the concrete was put in and was at the right strength, I reloaded the equipment for stressing and set off south. The construction site for work like this typically is not more than two days. This one, however, could be finished in less than a single day. Of course, there’s always the issue of the unions. They insist that one of their members to do the work. But, they don’t have anyone with the proper training for this kind of work. They call us and they send us two workers. We tell that they should just sit and watch while we complete the task as quickly as is possible. These days Beam and Block Floor is very common and people argue that it is more durable. 

We were on our second journey across the rings beam, bringing the stress upwards in stages in order to avoid destruction to columns. I had planned to connect every cable 4 times during the process of stressing. Then there was a huge sound and all I could see was people jumping off the building!

We stopped the stressing , and then inspected each column to see if there were cracks. I also climbed up to at the very top of the dome’s support and inspected at the top. The dome had been raised by about 1 inch from its top. It was pulled to the point that one them was cracked!

I called for the engineer. I inquired of what to do next. The engineer’s response was “is it blocking the dome? This means that your work is done.” He was able to design the ring beam the same way the designs he creates when using steel bars. Even if the engineer was aware of what was going to happen (which I doubt) that he was, he didn’t inform us. We relayed the details to the contractor, and then packed in for the return journey.

Concrete reinforced columns are typically employed to support the weight of a structure. They are used to transfer the load to a safe soil bearing capacity. In some instances, a structure might have only walls that bear load. They may not be able to accommodate an additional floor over. The home may also require an upgrade of the roof from lightweight materials such as galvanized iron sheets to more robust concrete or clay roofing tiles. This will require more bracing to handle the extra loads.

The concrete reinforced columns within an building could be finished with the plaster render, cladding’s or left in an underlying concrete colour. No matter what the final finish is, it must provide good aesthetics to wall facades. They can be constructed on their own or inside the fabric of the building. They could be of the typical rectangular or square shape however, they could also be the circular form. It is essential to identify the areas where it is possible to build columns. This ensures that all necessary supports are in place prior to cutting are made in a safe manner.

The process of creating reinforced concrete columns is to mark out every point to be added columns. The roof and walls are supported by bracing and props. The columns should be set at the corners of buildings as well as any load bearing wall intersections. The wall is then cut until it reaches the beam level. The concrete at the beam level on the roof is cut and removed in order to reveal the reinforcements. The opening in the wall should be an masonry toothing. A pit is dug to accommodate the foundation column and column starter bars. The column’s base are then cast and vibrated thoroughly.

The column starter cures within seven days. Further reinforcement is added to the roof’s level and then joined with beam steel. Hoop iron is made by alternating the courses that pass through the steel at both wall’s edges. This allows for the walls to strengthen following the cutting. Formwork is then completed. Concrete is poured and then is then vibrated. The formwork is removed after 7 days after curing. The process is repeated for each location where the column will become an reinforced concrete column. The correct finish is applied to match the wall’s surface.
