Definitions

  • the present invention relates to a removal/dismounting apparatus for building units, which is adapted for placement between a unit to be removed and a supporting wall of the building.
  • Finnish patent application FI 981796 discloses a stripping device for wall cladding, which is carried in use by a supporting cable and which includes an elongated beam with a torsion bar articulated in its bottom end, and which is fitted with a pressure cylinder between a top end of the torsion bar and a top end of the beam for pushing the torsion bar at its top end outward of the supporting wall surface.
  • This device requires manual placement between the wall and the cladding and it is not capable of removing for example sections of a wall panel or unit present between window openings on top of each other.
  • the device In the process of tearing down high- rise objects, such as apartment buildings, the device requires the use of scaffolding in order to enable pushing of the device by manual force between the wall and the cladding.
  • a removal/dismounting apparatus of the invention comprises a body member, which provides a wide supporting surface bearing in use of the apparatus against the supporting structures of a building to be demolished, a hydraulic cylinder mounted on the body member, as well as a spreader element connected pivotably to the body member and the hydraulic cylinder and having its dismounting end provided with a removal/crushing element for applying a loading force to the inside surface of the dismountable unit over a relatively small area, the articulation between the spreader element and the body member being located at the opposite end with respect to the dismounting end, and that the apparatus is adapted for connection by its body member mechanically to the lifting arm of a working machine, the hydraulic cylinder being adapted for connection to the working machine's hydraulics, the apparatus being thus operable by means of the very working machine's controls, thereby enabling operation of the apparatus in various positions.

  • Fig. 3 shows an apparatus of the invention in connection with a working machine
  • Fig. 4 shows an apparatus of the invention in a schematic longitudinal section.
  • the apparatus comprises a body member 1, which establishes a wide supporting surface la bearing against a fixed wall unit 4 of the building.
  • the body 1 is pivotably fitted at an articulation 16 with a hydraulic cylinder 6, having the rod of its extending piston provided with a 5 spreader element 2 which is linked by one of its ends to the body member 1 at an articulation 8.
  • the spreader element 2 has its free end 2a designed as a removal/crushing element which in use of the apparatus applies a loading force to the inside surface of a dismountable unit 3 over a relatively small area while the body member 1 has its supporting surface la bearing against0 the fixed wall unit 4 over a substantially larger area.
  • An optimal relationship for the surface areas of the bearing surface la and the removal/crushing element 2a can be determined e.g. experimentally, and the relationship or ratio can be e.g. within the range of 10:1 to 50:1.

Abstract

5 Tiivistelmä Keksinnön kohteena on hydraulitoiminen rakennuselementtien irrotus-/purkulaite (10), joka on sovitettu asettumaan purettavan elementin (3) ja rakennuksen tuki- pinnan (4) väliin. Laite käsittää runko-osan (1), joka muodostaa leveän tukipinnan, 5 joka laitetta käytettäessä tukeutuu purettavan rakennuksen tukirakenteisiin (4), runko-osaan järjestetyn hydraulisylinterin (6), sekä runko-osaan (1) ja hydraulisylin- teriin (6) nivelletysti (8, 9) liitetyn levityselimen (2), jonka purkupäässä on irrotus- /murskausosa (2a), joka kohdistaa kuormitusvoiman purettavan elementin (3) sisä- pintaan suhteellisen pienelle alueelle. Levityselimen (2) ja runko-osan (1) välinen 10 nivelkohta (8) sijaitsee purkupäähän nähden vastakkaisessa päässä. Laite (10) on järjestetty liitettäväksi runko-osastaan (1) mekaanisesti työkoneen (11) nostovar- teen, hydraulisylinterin (6) ollessa järjestetty liitettäväksi työkoneen hydrauliikkaan, jolloin laite soveltuu käytettäväksi työkoneen omilla säätimillä sallien laitteen käytön eri asennoissa. 15 Fig. 1
