Masonry STONE

 

Called to the traditional masonry construction consisting of walls and walls erected for various purposes, using the manual placement of items or materials that compose them (called masonry) that may be, for example:

- Bricks

- Precast concrete blocks

- Stone, carved in regular shapes or

This system allows a reduction in waste materials and generates load-bearing facades It is suitable for construction in high altitude. Most of the construction is structural.

The interlocking arrangement of the materials used on the walls is called rigging.

Formerly, clay was also used, to which was added other natural elements such as straw, and in some rural areas cow dung and horse.

In some cases it is desirable to build the wall without using mortar, as in the case of "drywall" or "dry rope". These type of walls is typical of traditional rural buildings, for example, in the Alpujarra region of Andalucia in Spain.

 

When the element that makes up the wall is a foundation stone at the factory resulting in bone called ashlar, in which the blocks are placed dry without material that comes between them.

 

 

When the element that makes up the wall is masonry, the factory is called dry masonry, which are placed without mortar masonry that one, and most are coined with gravel.

 

nonbearing

Is one whose primary function is to frame the walls that serve to divide spaces without express or implied function of supporting the roof or upper levels. This forms partitions or masonry facades on buildings with bearing concrete frames, steel or even wood.

bearing

The masonry bearing imposes, in addition to the characteristics described above, according to the type of exposure, the need for superior strength in the elements, sufficient to withstand the loads to be borne, or have a strength such that the structure is designed to it. So much for the units, but as a whole, shows the involvement of the reinforcement, which has given the size that has the currently masonry within the structural systems.

In exterior walls

The exposure conditions in facades, foundations, etc.., Where water may be present, whether one side wall is supporting or not, entails the need of units of low permeability and absorption in order to prevent the entry of water through the wall.

Of course, this phenomenon is greatly reduced when the wall is protected, additionally, by means of plasters, paints, waterproof, etc.

From the standpoint of resistance, it does not appear as critical as long as the support elements and is stable with time.

In interior walls

In interior walls or partitions, minimum conditions are the hydraulic loads or thermal solicitations.

Under these conditions dimensional uniformity and stability of the units deserve special care, in order to reduce the amount of finishing materials and prevent cracking of the walls by separation of the units and the mortar.

The reinforcement according

The presence of reinforcement in the masonry determined its release, as a structural system, from the bonds of the resistance to compression, tension and shear.

 

all concrete

The masonry structural "concrete whole" is, rather than an alternative, a real possibility for allowing thermal performance of all building modular way using a very limited number of resources, in terms of materials, all grounded in the use of cement (injection mortars, mortar paste, concrete blocks, concrete slabs, etc..).

Unreinforced (traditional or simple)

Unreinforced masonry has once been used in the same way as clay masonry.

This is no longer possible in the light of modern structural codes, although number of works were executed in this way during the 1950s and 1960s.

Reinforced (structural)

The reinforced structural masonry has made it possible to extend the historical concept of the masonry wall structures, to make them much thinner and with heights up to 20 floors, making it economically feasible to construct concrete masonry buildings.

Although we have been involved in structures up to 14 floors, predominant use of structural masonry applies to dwellings of one and two levels as well as 5-story multi-family units.
