he invention relates to an accessory connecting scantlings with beams. It is composed of the wooden screw 1, the height-adjusting mechanism 2, the angular lamella 3 destined for the scantling housing, the washer 4 fixing the insulating material, and the caps containing the sealing material. The wooden screw 1 screws into the previously opened hole, it penetrates the insulating plate 13, the asphalt cloth 14, the planking 15 and partially the beam 16. The cap 5 of the sealing material is introduced into same hole. Upon screwing, the wooden screw 1 opens the cap 5 and the sealing material is released to seal the asphalt cloth 14 at the perforation point. After the screwing is finished, the head of the wooden screw 1 fixes the insulating plate via the washer 4. Finally, the scantling is leveled at the desired place by means of the height-adjusting mechanism 2. The advantages of the invention are: uniform heat insulation, double shell construction, lower resistance of the heat-insulatingplates, repair of the asphalt cloth at the perforation point, and placement of the scantlings at the accurate places. |
