Briefing

Researchers from the Technical University of Madrid (UPM) have developed a device to improve the encounter between masonries composed of materials of different dimensions or nature. It resolves the constructive encounter between masonry elements, when using pieces of different measures. This invention is framed in the technical sector of the instrumentation in the field of Architecture and Civil Engineering.

 
Technology Solution


This device allows to fix different masonry walls and composed materials of different dimensions or nature, through the introduction of metallic elements, made of galvanized steel. It consists of two types of components, one vertical, located in the joint between the different masonries, and other horizontal, introduced in the interior of the courses.

The vertical component can be continuous or formed by discontinuous elements, aligned along the joint.

The number of elements, along the vertical component, will be in function of the rigidity that you want to give to the union and applicable technical regulations and it  depends on the materials used.

 "This solution resolves a constructive problem which consists in the appearance of cracks between two masonry elements"

 
Market demands

  • Construction:
    • CTE-DB-SE-F (compulsory regulation) contemplates the possibility of building walls composed of two sheets of different bricks fixed with steel bars, but giving the solution for the case of two sheets composed of exactly the same bricks.
    • Among the types of walls that are defined are the cappuccino wall, composed of two sheets of bricks locked with some material, as they may be corrugated steel, and bent, with identical solution wall bars, but locking both sashes with brick arranged perpendicularly to the plane of the wall.
    • In both cases the proposed solution involves using two panels formed by elements of the same dimensions, running out to solve the case of two sheets composed of pieces of different sizes, and even of a different kind.
    • Real problem to the project usually walls of varying heights of course, which are resolved in project or work providing solutions that are not always correct and can never be optimal.
 
Market potential

  • Meteoric growth in construction sector (around 70%) concentrated mainly in China, USA and India [Oxford Economics and Global Construction Perspectives].
  • An employment increase by 33% is expected in the USA during the period 2010-2020, reaching a total of 1.8 million jobs in the sector in 2020 [Department of Statistics, USA].
  • Expected growth of the sector in Spain by 2.5% in 2015-2020 [Oxford Economics and Global Construction Perspectives].
  • Potential housing demand will be located above 300,000 households between 2011 and 2016 in Spain [BBVA Bank,2011].

Competitive advantages

  • Valid solution for both new construction and renovation.
  • Effective for walls and slabs of every kind and nature.
  • Prefabricared elemente, easy to carry and handle.
  • It solves the existing constructive problem to lock walls composed of different base materials.
  • Enable to facilitate or improve the blinding between perpendicular walls, whether of the same or different materials.

"The facades often combine walls of brick face with other continuous redressed (single-layer). Our contribution allows to solve the conflicting blindings"
