2.2.4. Fitting
The constructions made of CONCREWALLtip PCS, PCD and PCSol-type panels areperformed without difficulties within a preciseusual work.
The mounting is in compliance with themounting sheets elaborated by SCHNELL HOUSESA from Italy and the technical regulations intoforce regarding the works’ execution inconstruction.
Handling, transportation and warehousingof the PCS, PCD PCSol-type panels which are partof the bearing and non-bearing elements are madein conformity with the provisions of themanufacturing company.
For the bracing of the PCS, PCD panels forwalls profiled tied bars are mounted on the supportlayer, as a result of the structural calculus, beingpositioned on the both sides of the panel in order toensure the continuity of the elements within thestructure.
The distance between these tie bars shall beequal to the distance between the reinforcementmeshes (the thickness of the EPS core plus 25mm),that is 20…30 cm, being aligned in connection withthe external mesh in the case of the simple PCSpanel, and for the double PCD panel being alignedtoward both external and internal meshes.
The tie bars shall be straight and embeddedin a foundation. These are tied to the panels’reinforcement meshes (Fig.4,5).
A special attention shall be drawn upon ona safe embedment into the gunite of thereinforcements which connect the panel and thefoundation, the contact between the tie bars andpolystyrene being avoided.
The connection between the panels is madeby overlapping the reinforcement mesh on apanels’ surface of 50cm. These connections aremade with metallic wire or clips.
At the jointing of the panels and in theopenings an additional reinforcement shall beapplied: corner mesh for the corners, flat mesh forthe openings reinforcements or other zones inwhich the initial reinforcement mesh has beenremoved, mesh for repairing the continuity of thepanels’ shape.
The bordering on the inside of the openings(depending on the walls’ thickness) is made oflongitudinal reinforcement resulted from the
structural calculus, U type mesh and weldedmesh positioned on the panel’s sides inclined at45º which is tied to the external reinforcementmeshes, mesh which is provided at the same timeas the PCS and PCD panels.
Both the details of the openings’bordering and those of the wall panels’ jointingare presented in fig. 4...13.
The alignment of the EPS sheets and theirverticality are checked during the mounting; forensuring the stability, a temporary horizontalsupport made out of wood or aluminum or anyother elements adequate to the purpose isprovided ( fig-14 a).
The panels’ eccentricity measured withlead wire shouldn't oversee 6 mm over themedium generating line.
The margin of error of mounting theadjacent frames of the overlapped panels must beof maximum 15mm. Any error which doesn’tcomply with the aforementioned tolerance limitsis considered to be exceptional and the stabilityof the elements on the matter shall be checked.The mounting of the accessories for theinstallations shall be done before the concrete’slayout. In case of mounting some rigid tubes, thereinforcement mesh may be clipped; itscontinuity shall be subsequently readjusted bymeans of additional meshes placed on thatspecific area, as to ensure an overlapping on theinitial mesh with at least 15 cm – see figure 14b).
The guniting of the panels is executed byusing pneumatic protection devices connected toan air compressor with appropriate power orconnected to a guniting machine.
The pneumatic guniting (fig.14c) shall beexecuted in two layers: the former layer whichshall cover the reinforcement mesh, while thelatter shall cover the finishing one in order toachieve a thickness of 3-5 cm.
The finishing shall be the Designer’schoice, and conventional materials shall be used.
The prefabricated panels for floors shallbe mounted after the wall panels andreinforcements for flanges have been assembledbut before the process of exterior guniting withconcrete. The „PCD” panels for floors shall beassembled after the nucleus has been poured inorder to ensure the stability of the wall panel(fig.14d).
AT 010-01/108 - 2008 Page 8 of 29
For the fitting of the prefabricated panelsfor floors or roofs, wooden props and smallsustaining wooden-beams are provided, in order toavoid the panels’ distortion under the loadingsaction and afterwards 5 cm of concrete has beenpoured on the superior side and the inferior sidewill be covered (3 cm thickness). Assemblingdetails are presented in the fig. 5, detail D, fig.11,details D, H, E.
While fitting the CONCREWALL panels,concrete shall be added to the exterior layers of thebearing walls made of PCS panels, to the core ofthe walls made of “PCD” panels, to the floorsmade of “PCSol” panel. Superficial layerscompleting the PCD and PCD shall be daubed(used in such cases, the same as non-bearingwalls). The concrete and plaster specific featuresshall be established by the Designer.
In case of the multistage buildings, thesequence of the phases shall be repeated from thefloor, over the ground floor to the next floor, takinginto consideration that the bellow elements of thesuccessive loading will be executed only after thegunited concrete’s aging.

SCHENLL HOUSE Company from Italy executes CONCREWALL PCS panels for bearing andnon-bearing walls, PCD for bearing walls, PCSol for floors.
The CONCREWALL PCS type panels are sandwich panels made of EPS fire proofing expandedpolystyrene core fitted on both sides with a concrete layer each, slightly reinforced and the PCD panelmade up of two sheets of EPS with a reinforced concrete layer cast on the interior and two more exteriorconcrete layers, slightly reinforced.
The CONCREWALL– PCS panels shall be executed by means of a "sandwich" made up of twomeshes between which polystyrene of certain thickness is introduced.
The two meshes shall be rigidly connected by welding with connectors from potassium zincatewire crossing the polystyrene at least 40 times/mp.
CONCREWALL – PCD – panels shall be executed from two simple panels between which theresistance concrete is cast.
The two panels are rigidly connected with zincate wire connectors crossing the space in which theconcrete shall be cast.
The CONCREWALL – PCSol panels shall be executed from an EPS mesh within two meshes ofreinforcement welded with galvanized wire. The two meshes are connected by means of weldedconnectors perforating the EPS sheet.
The technical features of the panels executed in compliance with the manufacturing conditionsand the control of the work quality allow the execution of resistant bearing walls, ensuring safety duringthe exploitation. Panels shall be mounted on the basis of the technical documentation provided by themanufacturer. Special attention must be given to the process of covering in gunite the jointreinforcements between the panel and the foundation, by avoiding the contact between the anchor barsand polystyrene. On the client’s request, the panels mounting process shall be technical assisted by thecompany’s representative.
In order to establish the CONCREWALL panels’ technical performances experimental trials havebeen performed by METALLURGICA LEDRENSE SOC.COOP, RIVA ACCIAIO S.p.A. LAPI S.p.A -Laboratorio Prevenzione Incendi, ISTITUTO GIORDANO S.p.A, UNIVERSITÀ POLITECNICA DELLEMARCHE - Dipartimento di Architettura, Costruzioni e Strutture, CSI S.p.A-Italia; INCERC BranchTimisoara. The synthesis of the trials results shall be presented in the Table 1 and confirms thecompliance within the stipulated limits.
During this technical agreement validity period, the manufacturer is bound to comply with thequality technical conditions. The technical data shall be submitted to the technical agreement assessor,for the purpose of the drawing conclusions upon the CONCREWALL TYPE PCS, PCD and PCSol panels’behaviour in Romania, in real conditions.
