Method for joining building boards

A method of producing a floor by laying and mechanically joining floor panels in parallel rows, wherein said method comprises the steps of:

• (a) providing floor panels wherein relative positions of the panels during the method can be defined to include first and second mutual positions, a first mutual position in which (i) two adjacent panels are held in an angled position relative to each other and (ii) upper portions of adjacent edges of the two panels are in mutual contact, and a second mutual position in two adjacent panels are (i) located in a common plane, (ii) mechanically locked to each other in a first direction that is at right angles to the common plane, (iii) mechanically locked to each other in a second direction, that is at right angles to said first direction and to the adjacent joint edges, as a result of a first locking member disposed at one of the adjacent edges being connected to a second locking member disposed at the other one of the adjacent edges, and (iv) being displaceable in relation to each other in the direction of the adjacent joint edges,
• (b) bringing a new one of the panels into an intermediary position where (i) a previously laid first one of the panels is located in a first row, (ii) a second one of the panels is located in a second row and is in said first mutual position in relation to the first panel, and (iii) the new panel is located in the second row and is in said second mutual position in relation to the second panel and is in a position relative to the first panel such that a mutual distance is present between the upper portions of the adjacent joint edges of the new panel and the first panel;
• (c) while maintaining said second mutual position between the new panel and the second panel, displacing the new panel relative to the second panel into said first mutual position in relation to the first panel;
• and
• (d) angling the new panel and the second panel together into said second mutual position in relation to the first panel.

A method of laying and mechanically joining rectangular floor panels in parallel rows, the method comprising the steps of:

• (a) placing a new one of the panels adjacent to one edge of a previously laid first one of the panels in a first row and adjacent to another edge of a previously laid second one of the panels in an adjacent second row, such that the new panel is spaced from a final position relative to both the first and second panels;
• (b) displacing the new panel towards the first panel such that a locking element of a resilient locking strip disposed at one of the new panel and the first panel snaps up into a locking groove disposed at the other one of the new panel and the first panel and to thereby mechanically lock together the new and first panels in a first direction that is at right angle to a principal plane of the first panel and in a second direction that is at right angles to the first direction and to the thus connected set of edges of the new panel and the first panel;
• and
• (c) displacing the new panel relative to the first panel in a direction parallel with said connected set of edges, while maintaining the new and first panels locked together in said first and second directions, towards a final position until a locking element of a resilient locking strip disposed at one of an another edge of the new panel and said another edge of the second panel snaps up into a locking groove disposed at the one of the another edges, whereby the new panel and the second panel are mechanically locked to each other in both the first direction and the second direction with respect to the thus connected set of another edges.

A method of laying and mechanically joining floor panels in parallel rows, wherein each two adjacent panels of the panels are arranged to be brought into a mechanically locked mutual position by placing the panels at a mutual distance in a common plane and displacing one of the panels into engagement with the other one in a direction that is at right angles to adjacent edges of the two panels, in which mechanically locked mutual position the two panels are (i) located in the common plane, (ii) mechanically locked to each other in a first direction that is at right angles to the common plane, (iii) mechanically locked to each other in a second direction, that is at right angles to said first direction and to the adjacent joint edges, as a result of a first locking member disposed at one of the adjacent edges being connected to a second locking member disposed at the other one of the adjacent edges, and (iv) being displaceable in relation to each other in the direction of the adjacent joint edges, wherein said method comprises the steps of:

• (a) placing a new one of the panels adjacent to a previously laid first one of the panels in a first row and adjacent to a previously laid second one of the panels in an adjacent second row, such that the new panel is spaced from a final position relative to both the first and second panels;
• (b) displacing the new panel towards the first panel until the new panel and the first panel have been brought into said locked position;
• and
• (c) displacing the new panel relative to the first panel and towards the second panel while maintaining the new panel and the first panel in the locked mutual position.

A method for disassembling floor panels which have been mechanically joined in parallel rows, wherein two adjacent panels of the panels are arranged to occupy first and second mutual positions, a first mutual position in which (i) the two panels are held in an angled position relative to each other and (ii) upper portions of adjacent edges of the two panels are in mutual contact, and a second mutual position in which the two panels are (i) located in a common plane, (ii) mechanically locked to each other in a first direction that is at right angles to the common plane, (iii) mechanically locked to each other in a second direction, that is at right angles to said first direction and to the adjacent joint edges, as a result of a first locking member disposed at one of the adjacent edges being connected to a second locking member disposed at the other one of the adjacent edges, and (iv) being displaceable in relation to each other in the direction of the adjacent joint edges, wherein said method comprises the following steps for taking up a given panel located in a given row, said given panel being in said second mutual position in relation to an adjacent first panel in an adjacent row and also in said second mutual position in relation to an adjacent second panel in the given row;

• (a) angling the given panel and the second panel together into said first mutual position in relation to the first panel;
• and then
• (b) while maintaining said second mutual position between the given panel and the second panel, displacing the given panel relative to the second panel in a direction away from the first panel.
