In the past most of the marble walls was done with closed board


System boards

The meeting is not simply the space between the perimeter of the slabs, and is tasked specifically to allow free movement of the slabs caused by temperature fluctuations or any adjustments to the supporting structures or anchor.

The boards can be either open or closed.

Meeting closed
Are closed together, even allowing movement of the slabs, have a distance of 2 / 3 mm. In the past most of the marble walls was done with closed board. The adoption of this type of board generally allows installation on site of slabs of small dimensions and very thick.
The tendency to increasingly reduce the thickness of the slabs and the greater elasticity of the existing building structures that Read the rest of this entry »


It consists of an integrated set of items with the static function to set the external cladding of building structures


Anchor System

It consists of an integrated set of items with the static function to set the external cladding of building structures, the latter being forced to bear the agents loaded on it and, in particular the wind.

The anchoring system may consist of:
specific elements “Local Fixing”
an anchor structure “spead Fixing”

In the first case, however, lost one of the main advantages of the ventilated facade as anchor using specific elements, including cladding elements of small dimensions, are to create a large number of thermal bridges that determine a sensible increase heat dispersion.

The materials used today by the hooves are treated type steel or Read the rest of this entry »


Usually present as a uniformly distributed layer of mortar on the wall (plaster mortar with a thickness of 1-2 cm.)


Ventilated Facades – Supporting structure

The functional elements that make up the ventilated facade are:

Layer wall bracket
Monolayer type may be composed of a single stratification of material, or it may be of a multilayer, essentially consisting of more than a stratification of materials. Depending on the type of material used, the support layer has a determining influence on the behavior of the system, because of the different coefficients of deformation that are subject to the elements that compose it.

Adjustment layer
Usually present as a uniformly distributed layer of mortar on the Read the rest of this entry »


Work placement in a proper way for raised floor


Work placement in a proper way for raised floor

In case of new building works on the walls must have been completed with at least 60 days and wet finishing with at least 30 days.

– Firstly it is necessary to demonstrate the possible unevenness of the fabric and after removing the dust from the slab is necessary to dust treatment especially in the case where the span under the floor is used as a channel for air conditioning. It is advisable to check that the treatment is consistent with the dust tail to the columns.

– Then, before the installation of equipment, the installer will have to Read the rest of this entry »


Columns that have the function of support panels and transmission of loads to the supporting surface


The large plane ground.

The components of the supporting structure are:

– Columns that have the function of support panels and transmission of loads to the supporting surface. Usually made of galvanized steel, allow, thanks to a mechanical threaded system to regulate the height over the ground floor (which can range from 10 cm. Up to 1 m) and offset even the minimal support surface uneven.

– Skiing, they also manufactured in galvanized steel columns connected horizontally improving stability and increasing their capacity. The sleepers can be of different length and have tapered according to load requirements.
– Fittings that arranged all along the sleepers and the head of the columns have a role soundproofing and dust.

Type
– Structure-only columns

The supporting structure is simpler, since only consists of Read the rest of this entry »


Want to go for authentic and real build system

Raised Floors – DESCRIPTION

Authentic and real build system

Authentic and real build system, a raised floor is raised off the ground cover under which it is possible to create an adequate system of distribution networks (electricity, lighting, HVAC) transmission (computer, telephone) and automation (building management alarms, fire systems and security).

The ease of removal of modular panels that make up the raised floor allows quick and effective maintenance operations without the need to work on the walls, limiting the costs and time.

These characteristics, coupled with the increasing reliability of the supporting structures has now raised floors are the most commonly used in offices, showrooms, dealers and all the spaces for productive activities.

With regard to traditional land, the benefits of a raised floor are:
– Freedom to rethink environments over time depending on Read the rest of this entry »


Has traditionally been considered the concrete as a building material composed of cement


Concrete Additives

Has traditionally been considered the concrete as a building material composed of cement, aggregates and water. However, even today still continues this idea, are now very few professionals in the building that do not consider the concrete as the ultimate building material composed of the three above components plus a fourth component, indispensable in the most cases, the concrete additive.

“Concrete Additives are substances or products incorporated into the concrete before mixing (or during or in the course of an additional mixing) at a rate not exceeding 5% by weight of cement, produce the desired modification in fresh or hardened in some of Read the rest of this entry »


Aluminum formwork systems – easy way to speed up construction

Aluminum formwork systems – easy way to speed up construction.

The modular aluminum formwork builders to give you working with an integrated prefabricated great for creating a wide range of products. This method of formwork is a new option for housing projects, generating efficiency, productivity and savings. On the other hand, this system allows panels in a single day to empty walls and concrete slabs due to their simultaneous vacuum cycle, which also provides insurance earthquake resistant behavior.

The forms, have to give the concrete function as planned, providing stability as fresh concrete, ensuring the protection and proper placement of Read the rest of this entry »


One of the main segments of the market segment is building the MC – Steel fabricated buildings

Metal Ware

The use of steel in the construction of prefabricated buildings

The concept of “Metal” (the IC) includes a wide range of products, which are sometimes very different among themselves, and combines them only one thing – they’re all made with the use of any metal, both ferrous and nonferrous. In addition, most products are bundled with other materials and a modular design. All items under the term “metal construction” can be divided into the following groups:

Building metal constructions combine in himself all types of metal building frames for any purpose (Roof Trusses, columns, girders, connections, beams, roof structures, canopies, dome construction, etc.)

Protecting designs – galvanized corrugated sheet, sandwich panels, sandwich, window frames and blocks, metal doors and gates, additional elements to them.

Modular buildings or block-containers – all block construction.

Metal work – tanks, tanks and other containers for Read the rest of this entry »


On the nature and magnitude of deformation affects not only the magnitude of loading, but also the rate of load application


The mechanical properties of building materials
The mechanical properties reflect the ability of bodies (material) to resist the force (from mechanical stresses), heat, shrink, or other stresses without breaking the established structure. In turn, energized understood measure of the intensity of internal forces generated by the action of loads, temperature changes and other factors or causes. Virtually stress is defined as the inner force per unit area, with a mean force of the inner strength of the particles located on one side of the site, the particles that are on the other side of this site. Usually determined by calculation the normal (perpendicular to the plane) and shear stress expressed in MPa in SI.

The mechanical properties are separated by the deformation and strength.

Characterize the deformation properties of a material’s ability to change the shape or size without any variation in the magnitude of its mass.

Deformation – changes in volume or shape of solid or plastic body without weight change. The principal types of deformation – tension, compression, shear, torsion and bending. All of them may be reversible or Read the rest of this entry »
