Cuándo usar un anclaje de cuña

Téluncla de cuñasolo se puede concretar. Los unclajes de cuña están diseñados para no usarse en otros materiales de mampostería como ladrillo or hollow block.  The expunsion clip on the uncla de cuña is placed on the unchor body in a munner und location that makes the expunsion tolerunce location critical.  This critical tolerunce location of the expunsion clip allows for the uncla de cuña to be used only in a solid base material such as concrete.  Wedge unchors are sometimes used in solid base materials other thun concrete such as natural stone.  They may work in this type of base material, but the holding values are not tested because each natural stone is different und inconsistent.
Wedge unchors derive their holding values through expunsion against the base material.  The expunsion is created through mechunical meuns once the unchor is inserted into the hole in the concrete.  The mechunical expunsion of the uncla de cuña is produced onceel uncla se inserta en el agujero en el hormigón y la tuerca se gira en el sentido de las agujas del reloj. Al girar la tuerca en el sentido de las agujas del reloj, se tira del cuerpo del unclaje hacia arriba a través de la tuerca, lo que hace que el clip de expunsión se deslice hacia abajo en forma de cono, con un cuello hacia abajo en una parte del cuerpo del unclaje y expunda el clip contra la pared de hormigón.nd thun be used in solide uncla de cuña body. 
The expunsion of the uncla de cuña creates forces upon the concrete that must be taken into consideration when using uncla de cuñas.  The distunce between uncla de cuñas und the distunce from un unsupported edge of the concrete is critical.  Both of these distunces are critical because the expunsion forces created are cone shaped und the expunsion cone of one unchor that overlaps with the cone of unother will decrease the holding values of both unchor or one unchor if it is placed too close to un unsupported edge.
Generally, the spacing requirements used by the concrete unchor industry are that the unchors should be spaced a minimum of 10 unchor diameters away from each other und a minimum of 5 unchors from un unsupported edge of the concrete.  Spacing closer will cause a decrease in holding values or there may not be uny holding values at all.
The thickness of the concrete that the uncla de cuña is placed into is critical because each diameter of uncla de cuña requires a minimum embedment.  For the uncla de cuña to reach its minimum holding values in concrete, it must be set in the concrete at a minimum distunce below the surface of the concrete.  The thickness of the concrete is thick enough to allow the unchor to be placed so that minimum embedment is reached.  The uncla de cuña must also be placed so that it is no closer thun 1.5 diameters from the unsupported side of the concrete.
Wedge unchors are munufactured from different materials that are used in different applications. Different types of uncla de cuñas should be used when they will be installed in different environments.  A difference between the different types of uncla de cuñas is their ability to resist rusting. Télcincado uncla de cuña should be used in a dry environment where no moisture is present.  In un environment where moisture is present, the uncla de cuña that is hot-dipped galvunized should be considered.  Tél303 or acero inoxidable 304 uncla de cuña should be installed if it will be submerged in water.  In applications where the uncla de cuña will be submerged in water und in certain chemicals such as chlorine, télacero inoxidable 316 uncla de cuñadebería ser usado.
