Definitions

• the invention relates to a structure comprising at least one plank with an underside attached generally transversely to a topside of at least one joist, at least one mount placed between said underside of the at least one plank and said topside of the at least one joist, a base of the at least one mount with at least one first attachment hole, which is communicating with the underside of the at least one plank.
• Structures of this kind are widely used for example for floors in terraces, hoardings and pallets.
• the joist forms a bearing part of the structure. It has a relatively large height for being able to obtain the necessary moment of resistance against being bent.
• the thickness of the joist may be smaller than the width of the planks .
• the planks are normally attached to the joists with a little distance in between .
• Such structures have traditionally been assembled by means of nails or screws, which however can work up above the surface of the plank and cause a safety risk.
• the screws or nails can moreover be seen and detract from the aesthetic appearance of the structure and sometimes they also can discolour the area of the structure surrounding the nails or screws.
• brackets In order to avoid these problems angular brackets have been used for assembling the structures. The assembling operation by means of such brackets is however difficult and time- consuming.
• a sixth aspect of the invention providing a method for producing a structure consisting of planks attached to joists.
• novel and unique features of the invention whereby these features are achieved consist in the fact that at least one projection is formed on the base of the at least one mount with at least one second attachment hole communicating with the topside of the at least one joist, and that said at least one second attachment hole is offset from the middle line of the topside of the at least one joist.
• the assembling of the structure according to the invention is easily and quickly to carry out by simultaneously obtaining a strong and durable structure.
• the mounts of the structure moreover do not involve any risk for the users and since the mounts at least in the main are hidden, a pleasant aesthetic appearance is obtained.
• At least one second attachment hole is offset from the middle line of the topside of the at least one joist is moreover advantageously obtained that identical mounts can be used opposite each other on each their side of a plank to be fastened to a joist by means of the mounts.
• an expedient embodiment according to the invention can at least one hook be formed on the base of the mount at an angle of preferable about 90 degrees whereby that advantageous is obtained that the mount is easy to place in the correct position on the plank by only letting the at least one hook abutting the edge of the plank.
• the mounts can, according to the invention, be attached to the planks and the joist by means of screws through the first - and second attachment holes whereby hard wood can be used to the structure.
• the first attachment holes can be placed in the mount above the topside of the at least one joist. Countersunk screw heads should in this case be used.
• the two first attachment holes can be formed in the mount at either side of the topside of the at least one joist so that countersunk screw heads are not required.
• the mount can, according to the invention, moreover be placed between the associated planks and joists so that a space between said wood parts is formed. Opposite surfaces of the wood parts therefore are exposed to air preventing the wood against rotting.
• the mount can, according to the invention, furthermore have a mainly rectangular base, whereby the first attachment holes are formed in the base and at least one projection with the at least second attachment hole is protruding from the base.
• Each plank can, according to the invention, be attached to each joist by means of two opposite mounts which are turned 180° in relation to each other. Neighbouring planks are attached to the same joist in the same way and with a little space in between.
• the second attachment hole in the projection of the base of the mounts be placed in the space between two neighbouring planks whereby the mounts and thereby the planks easily and safely can be attached to the joist by means of fasteners like screws which are screwed into the joist through the second attachment holes.
• the space between two neighbouring planks need in this first embodiment of the invention to correspond to or to be larger than the diameter of the fasteners to be used.
• the second attachment hole in the projection of the base of the mounts can according to the invention be placed outside the space between two neighbouring planks .
• the first of two neighbouring planks is attached to the joist by means of e.g. screws screwed into the joist through the second attachment hole in the projection of the base of the mounts.
• the second plank then is moved sideways against the first plank so that the at least one second attachment hole of the projection of the base of the mount on the second plank is placed between the topside of the at least one joist and the underside of the first plank.
• the second attachment hole in the projection of the base of the mount on the second plank can in this position not be used for attaching the mount and thereby the second plank to the joist by means of a fastener like e.g. a screw.
• the second plank is however in this case secured in the structure by the projection of the base of the mount on the plank being hold between the topside of the joist and the underside of the first plank.
• the advantage of this embodiment is that the space between two neighbouring planks can be relatively small.
• the space cans e.g. be the same as the thickness of the hooks.
• the space can in another embodiment according to the invention of a mount without any hook be zero so that the side edges of two neighbouring planks are abutting each other.
• the projections on opposite mounts on neighbouring planks can both be in the space between neighbouring planks when the projection, in the mounted position of the mount, is placed above an area of the edge of the joist extending outwards in the lateral direction from the middle of the edge of the joist .
• the joists of the structure according to the invention will preferably be placed with a predetermined distance between their middle lines. Markings corresponding to the positions of said middle lines can according to the invention preliminary be marked out on the planks to be attached to the joists. The mounts are then attached to the planks with their base symmetrically arranged in relation to said markings.
• the mounts can easily and quickly be placed in the correct positions upon the planks when the middle of the base of each mount is indicated in advance.
• Such indication may, according to the invention, be in form of e.g. angular incisions in the edges of the base of the mounts.

• the projection is arranged at one side of the line between the incisions while there is no projection on the base of the mount on the opposite side.
• Opposite parts of the mount are bent an angle of e.g. 90 to form two hooks 10.
• the attachment holes 7 and 8 are oblongs except, in this case, the attachment hole 7' , which is round. Some or all attachment holes may within the scope of the invention be oblong or round.
• the joists of the structure are placed with a predetermined distance between their middle lines, and markings corresponding to the positions of said middle lines are marked out on an underside of the planks to be attached to the joists .
• Two opposite mounts are placed on each plank at each of the markings with their angular incisions coincident with the markings .
• the base of the mounts in the assembled state of the structure, will automatically be symmetrically arranged in relation to the middle of the joists.
• Each mount is placed on the respective plank with their hooks abutting an edge of the plank and the projection protruding from said edge.
