What are fundamental blocks PBS
Structural units represented by the foundation construction concrete elements which are made of heavy concrete of high class. Products are issued in the form of a cuboid. Blocks at the production stage can be reinforced with metal bars. This enhances the elements, so that they can withstand heavy weight loads.
Foundation blocks - are the building elements of heavy concrete
To facilitate the work of loading, unloading and assembling each element is equipped with two metal eyelets. To ensure reliable and strong connections products during their installation in the end parts of the blocks are made smaller recesses, which are filled with masonry mortar.
Judging by the title, foundation concrete blocks are mainly used for the construction of a reliable and strong foundations of various buildings. However, this is not limited to their range of use. CFC demand in the construction and installation works of any complexity.
They are often used for the construction of multi-storey buildings, technical purpose buildings, non-residential and industrial buildings. Due to the fact that with the help of products enables rapid construction process, the foundation blocks in demand in the construction of temporary and permanent fencing, large construction projects.
Advantages and disadvantages of reinforced concrete for the foundation blocks
Concrete blocks are recognized as the foundation popularity among builders in the construction of structures of varying complexity. This is due to specific advantages in manufacturing in comparison with the traditional way pouring concrete foundations.
The main drawback of the blocks is their high cost
The material has high strength properties, has a good load bearing capacity. It has high resistance to moisture, temperature variations and fire. Through enhanced frost resistance and reduced thermal conductivity degree installation of foundation blocks may carried out during the construction of objects in any climatic region, where work can be done at any time of the year.
The material is resistant to various natural phenomena, including the blurring of groundwater and frost heave in the spring of the year. Increased resistance material gives the right to perform laying of foundation blocks in adverse conditions, for example, in acidic soils and ice. The only exceptions are rocks.
The use of products in the construction of foundations provides a reliable and durable base in operation for at least 60 years. This is due to the fact that the products are manufactured in the factory, where the technology is strictly adhered to production and performed a hard laboratory quality control of the composition of the working solution, and finished products.
Foundation blocks have impressive dimensions and a regular geometric shape that facilitates quick and convenient assembling products. This greatly reduces the labor and time of the execution of works. After the closure assembly can immediately proceed to the next step without waiting for the setting solution. This feature provides an economic benefit that is especially important in large-scale construction.
for the foundation blocks are characterized by high resistance to moisture
Among the disadvantages of high cost can be isolated blocks. Significant weight concrete blocks for the foundation require the involvement of specialized equipment to install them. At the construction site should be enough space for equipment and storage of unused items. In addition, the space docking elements will not differ sufficiently tight, which would require the implementation of additional insulation measures.
As made foundation blocks: technology features
At the foundation of high-quality production of concrete blocks, each manufacturer must strictly to perform a sequence of actions and adhere to project the ratio of components ingredients. To prepare the working solution used cement powder, water and fillers.
Kneading is prepared in the forced type concrete mixer, where the mixture is to acquire a smooth consistency. The finished solution is supplied in special metal molds, the inner walls of which are pre-treated industrial lubricant. At this stage the valve can be laid, which affects the strength characteristics of the products and prices for the foundation blocks. Each form is divided into several compartments and equipped with removable sides, providing a quick and easy extraction of products from it using a crane.
The liquid substance takes place in a special process Vibrating machine
Moulder uniformly distributes the mixture, after which the concrete vibration occurs, which is done by the use of the portable deep vibrator or directly on the shaking table. At this stage the process is performed semi careful sealing substance.
Important!The duration of the vibration process is strictly regulated, because vibration will cause excess concrete bundle.
After vibrating trowel smoothed surface of the articles. Products demoulded, after which the film is applied on them a protective coating. Further blocks watered. The process takes place in the steaming chamber. Blocks left for 7 days for the final drying, whereupon the product selling gaining strength. Full strength of the material occurs after 28 days.
The dimensional characteristics of concrete blocks PBS
An important parameter of the concrete blocks are their sizes. The length, width and height of the product is strictly regulated by the current regulations. Selection block size determined based on the rated load of the object on the base, which must withstand the weight of the construction and to distribute it uniformly around the circumference.
Foundation blocks according to GOST produced in sizes 15
Important!Wrong selection of block sizes will lead to the subsequent destruction of the building.
From the dimensions of the blocks are directly dependent on the strength of the future structure, process and installation work elements, the period of the "zero cycle", the cost of products. Block sizes are also chosen based on the type of soil and its bearing capacity. The smaller the soil resistance, the blocks must be OVERALL. For the construction on the clay grounds should prefer the largest elements. For coarse soils suitable products of small size. The most popular option for small building is considered to be the foundation of 20h20h40 cm blocks.
Useful advice! To create a reliable and durable foundation must provide maximum packing density, that is carried out via raznogabaritnyh foundation blocks.
An important aspect is the thickness of the walls and ceilings, floors construction and its weight, which is determined by the size and structure of the type of construction materials. Also, the dimensions of blocks are selected based on the type of masonry. It should be remembered that the optimum amount is considered to be five blocks on the length of the wall.
Block sizes affect the process of construction
According to GOST, PBS blocks 15 are shown in different sizes. Length can be 880, 1180 and 2380 mm. Blocks release of width 300, 400, 500 and 600 mm. Height of the product may be 280 and 580 mm. The smallest element has dimensions 880h300h580 mm, and the largest - 2380h600h580 mm. Many manufacturers produce foundation blocks 200h200h400 mm which can be installed without the use of special equipment.
How to choose the size of the foundation blocks FBS
During the construction of the foundations of different sizes are used for foundation blocks, and the price per unit of product is directly determined by the dimensions of the element. For the correct selection of the number and size of FBD base scan is performed. At a special drawing applied all the elements of the base length and height. This takes into account ligation between the elements, which reaches 25 mm.
block width is chosen based on the thickness of the walls of the future construction. Here Slight overhangs above-ground elements. If a brick wall to be erected, the value of indentation should be about 40 mm on each side. For load-bearing structures of 640 mm in thickness can be used units 600 mm width for walls 510 mm - 500 mm size of the product.
Length is determined by the foundation reamer where to locate schematically elements of different dimensions so as to ensure a smooth laying them without a significant protrusions.
Width should select blocks based on the thickness of walls of buildings
Important!If you can not have a way to spread along the length of the base products of standard size, they can be subsequently split lengthwise.
With the construction of foundations and walls using blocks 580 mm high. Products with a value of 280 mm dobornyh used as components in the case of performing communication of inputs and outputs, holes in the base for air holes.
When selecting products dimensions important criterion is the weight of the foundation block, which affects the transport logistics. Mass of product is within the 380-1960 kg. It is necessary to choose a vehicle that will carry out the transportation of materials to the construction site. Based on the duty vehicles, buses is selected to be directly perform stacking articles.
Small blocks of the foundation small buildings
According to industry standard compact foundation blocks are available in lengths of 400 and 600 mm. Such products are characterized by high strength and low weight. Foundation blocks are made predominantly of heavy concrete grades that differ a good carrier capability that allows you to use the product to create the foundations of the structure of wood or foam.
Small foundation blocks may have a length of 40 and 60 cm
For their installation is not required to involve the lifting technique, which reduces paper financial construction costs. However, the use of foundation concrete blocks 20h20h40 cm increases labor and time period of the work.
Products are often used for the construction of foundations in sandy soils, walls, basements and cellars. A good and inexpensive solution is to create the foundation of the columnar blocks 20h20h40 cm for small houses or lodges. Such elements expedient to use in combination with a cast tape bases. As additional elements specialists often use a concrete foundation blocks 20h20h20 cm, using which can create the air vents at the base to the air holes or laying of utilities.
Compact foundation blocks fit not only in the construction of load-bearing walls, columns and fences - they it is expedient to use as support elements in the ground floors, basement and basement areas.
Varieties of concrete blocks under the base by material
According to GOST foundation blocks may be produced using different types of concrete mix. Depending on this, there are different types of products. Cement, concrete and concrete products are carried out mainly from heavy concrete grades that It helps to create blocks with maximum density, which are characterized by high carrier ability. Bases and structures by this type of foundation blocks, characterized by reliability and durability.
Silicate foundation blocks of concrete to produce a silicate with the addition of blast-furnace slag
Important! To impart additional strength in units ready solution is added crumb from basalt or granite.
Manufacturing silicate foundation blocks resembles brick manufacturing technology. The working solution used for silicate-based concrete, the amount of high grades of cement should not exceed 14% of the total. To obtain a sufficient strength batch is heated to a certain temperature and then subjected to slow cooling. To enhance waterproofing properties in the production of silicate products, ground blast furnace slag is added.
