Reinforced belt for woody floors
When it comes to constructing wooden floors, ensuring their stability and durability is paramount. One of the most effective ways to achieve this is by incorporating a reinforced belt. This technique provides additional strength, preventing sagging and increasing the longevity of the floor. Whether you"re building a new home or renovating an existing one, understanding the role of a reinforced belt can make a significant difference.
The idea behind a reinforced belt is not too complicated. It entails enhancing the wooden structure with a layer of reinforcement, usually composed of steel or composite fibers. This reinforcement lessens the chance of structural failure and aids in more evenly distributing loads. As a result, the floor is more resilient to wear and tear from regular use as well as the weight of furniture and appliances.
By installing a reinforced belt, you can improve the floor’s overall performance in addition to its strength. It makes the surface underfoot feel more substantial and comfortable by reducing vibration and deflection. It can also aid in resolving problems caused by the expansion and contraction of wood naturally, giving it more dimensional stability over time.
For homeowners and builders alike, the benefits of using a reinforced belt for wooden floors are clear. It offers a practical solution to common challenges and contributes to a safer, more reliable structure. In the following sections, we"ll delve deeper into the types of reinforcement materials available, installation techniques, and the specific advantages each method provides.
For wooden floors, a reinforced belt is necessary to improve the longevity and structural integrity of the building. A reinforced concrete belt is integrated to improve load distribution, reduce the possibility of floor deformation, and boost the structure’s overall stability. This easy-to-use yet reliable technique makes sure that wooden floors are sturdy and secure even when subjected to significant pressure and weight.
What is Armopias?
A monolithic reinforced concrete structure called Armopome runs around the outside of the building. It must unavoidably mirror the shape of the house, be closed, and uninterrupted throughout. It is employed to fortify the walls and stop the structure from deforming due to internal or external factors. A house’s strength is increased multiple times by a simple design. This is particularly valid for constructions made of porous blocks, such as foam and gas blocks.
An illustration of a reinforced formwork belt
Generally speaking, multiple reinforced belts are poured when building a house. The last one is done prior to roof installation, and the first one is done at the foundation level. Before constructing interfloor ceilings, a reinforcing structure must be put in place. The reinforced belt serves a number of crucial purposes, including:
- uniform distribution of the load;
- protection of gas and foam blocks from squeezing;
- strengthening the connection of the roof and rafters with the walls;
- increasing the spatial rigidity of the structure being erected.
In what cases is it necessary
Not every situation calls for the construction of a reinforced belt. Therefore, extra reinforcing is not required when building cast structures out of brick or wood. When it comes to building homes out of porous blocks, the situation is different. Building technology frequently necessitates installing a reinforced concrete belt for floors. When is a reinforcing structure required?
- a rafter system using studs, anchor bolts;
- beams are unevenly laid and create a point load on the porous material of the walls;
- a prefabricated foundation is used or it is not very deep;
- it is necessary to give rigidity to the structure being erected;
- the house is being built on loose soil that gives uneven shrinkage, or on an uneven surface, for example, on a slope;
- the structure is higher than 1 floor;
- a reinforced concrete belt under the floor slabs is necessary in the case of using porous blocks for building walls and excessive weight of the slabs themselves;
- negative external, natural factors (strong winds, seismic activity) affect;
- materials of different rigidity are used during construction.
How to make a reinforced concrete belt. Formwork construction
Usually, a wooden formwork is used to pour the armored belt into. The structure is 30 cm tall on average. Self-tapping screws are used to fasten the boards to the wall from both the inside and the outside. Three to five centimeters of fastening will do the trick. Additional ties must be used to connect the formwork’s inner and outer sections at a distance of 70–100 cm. Otherwise, the pressure from the concrete mass may cause the boards to separate in various directions.
Completed formwork with reinforcement
The formwork is typically the same width as the wall. However, in some instances, it is advised to place the boards 3 cm narrower in order to minimize heat loss through the reinforced concrete structure. Insulation can be placed inside the resulting interior space.
Manufacturing a reinforcement frame
Reinforcement is placed inside the finished formwork. The optimal size is from 8 to 12 diameters. If the house will be subject to significant external or internal loads, it is advisable to use rods of 12 diameter. Also, the amount of reinforcement used will depend on the load level. Cross rods are attached with a special wire or welded. The reinforcement frame is made on site, on the wall, because. . the metal structure turns out to be heavy. The rods are placed on special stars or other supports to create an active bottom layer, and the reinforcement does not directly adjoin the blocks. It is also necessary to retreat at least 5 cm on the sides so that the frame is completely recessed in the concrete. I. e., if the formwork boards are at a distance of 30 cm, then the width of the internal metal structure will be no more than 20 cm.
Foam blocks with a reinforcement frame inside
It’s best to wrap the studs in something, like cellophane, to prevent them from getting ruined when the armored belt is later filled with concrete.
If there won’t be any heavy loads on the building, your options are limited to a ladder-like reinforcement frame. If not, you will have to construct a parallelepiped-shaped metal structure. Indents measuring 5 cm on all sides must also be noted in this case. Leveling the reinforcement frame is necessary. If studs are used in the construction, they are put in place after the reinforcement frame is manufactured.
Pouring
The pouring of concrete is the last step. After mixing, the building mixture is poured into the formwork. The reinforced concrete belt needs to be constructed all at once; otherwise, it won’t be able to carry out its intended functions and the structural integrity will be compromised. Consequently, the armored belt may fracture at the intersection due to uneven loading.
Concrete is poured into the reinforced concrete belt.
To improve the adherence of the reinforced concrete belt to the top row of blocks, it is advised to create a "hedgehog" by inserting one part of the wire or nails into the blocks and filling the other part with concrete. The structure will become more robust as a result.
Concrete for pouring can be made on-site or purchased already made. Cement, sand, and crushed stone should be combined in a 1:3:5 ratio. Stir the mixture and add water to achieve the right consistency. You can also use a concrete pump when pouring. However, there’s a good chance that the solution will diverge the boards and damage the formwork if it falls from a great height. Thus, it is generally preferable to complete the process by hand. In this instance, you have to pour a new section of concrete right away after the previous one has solidified.
The bayonet method must be used to compact the mixture. To get rid of the spaces that arise when pouring concrete in sections, this is required. This is where a piece of reinforcement or a specialized tool come in handy. The solution is leveled at the conclusion of the process. The concrete will solidify in three to five days, at which point the reinforced belt will be ready to be removed from the formwork.
In the event that concrete is insufficient, the reinforced belt can only be divided vertically. I.e., concrete is poured to the height of the jumper, which could be a piece of brick, block, or board. The barrier is taken down the following day, and the solution is kept wet at the intersection by adding more water. This process is repeated until the entire armored belt is ready.
