Definitions

  • This utility model relates to a lock for horizontally and vertically connecting boarding plates into panels, whereas said plates are made of various materials, about one another directly or indirectly by an insert having a thickness of a boarding plate and a necessary width, and are used to pour concrete, especially in monolithic constructions.
  • a lock for connecting movable steel moulds for pouring concrete is known, e.g. from patent PL 108999.
  • This lock has a clamping ring made of coiled sheet metal on the whole length of contact with edges of boarding plates to be connected together.
  • a holder coiled of a barstock is welded from both sides to this clamping ring.
  • One side of a lock clamp is longer than another, in which a bore is drilled for mounting in it a bolt to be connected with edges of two boarding plates.
  • a lock for connecting boarding plates is also known from patent PL 172153, consisting of two jaws slidable one in relation to another, one jaw being movable, and another being permanently fastened to a guide.
  • a movable jaw has a head in which a screw is borne by its two pins, a thread of said screw engaging in its working position another thread provided in a bed of a guide to which another jaw is fastened.
  • a buckle-like head base comprises from its inner side a dual coupling system consisting of a pair of pins mounted in a distance L from a bottom side of the bed greater than a height of threads in the screw and in the bed when the lock is in its working position, as well as of a pair of stop blocks contacting with a protruding bottom edge of the bed in the working position.
  • a pulling lock for connecting boarding plates is also known from the European Patent Application No 0 311 876 A2, consisting of two catch jaws, one jaw being slidable, and another forming a monolith together with a guide, both being stabilized in a working position by means of a wedge pushed into a recess in the guide. These jaws are fixed and pulled in the determined working position by a strutting force created by a wedge being pushed in.
  • a lock for quickly connecting panel boarding plates into specific structures is also known from the European Patent Application No 0 537 403 A1, consisting of a U-shaped element ("C") forming a supporting beam.
  • Said supporting beam has in its longitudinal surface a recess working as a guide for a wedge pulling together jaws, one of which is fixed to the beam, and another is movable.
  • Said wedge is parallel to the beam surface and is located under a bolt connecting said pair of jaws.
  • the wedge has a flat shape with a guiding element on its bottom surface, and its outer surface is convergent, said wedge having at both its ends stops forming feet for driving in and knocking out the wedge.
  • a clip for connecting together aluminum boarding plates is also known from the utility model PL 56 711 , said clip consisting of a carrying rectangular metal plate to which there is fixed a bolt, one end of which is formed as a tapered cone, and another protrudes beyond the lower surface of the carrying plate by one third of the whole length of said bolt.
  • a spring hook-shaped clamp coiled from one round section bar. This clamp is so formed that by connecting boarding plates into panels a spring force presses boarding plates to a carrying plane, providing a precise and tight connection.
  • From the utility model PL 55 001 a linker for connecting edges of boarding shields when making boarding systems for concrete building constructions is known, said linker consisting of a flat beam ended with a claw.
  • said beam is pivotal ly connected with a fork by means of a bolt.
  • Said fork is provided with two claws, and in a cross-bar of a claw it has a threaded bore provided with an eye-screw resting with its end on the beam.
  • a tip of the beam claw is directed to a point between tips of the fork claws.
  • Clipping boarding plates together by means of locks having a profile closed from three sides could cause a risk that a free space formed in a lock would be filled with concrete, and disassembling of such a connection would be difficult in the future.
  • This object has been obtained by creating a lock for horizontally and vertically connecting boarding plates into panels, said plates being made of any material having an increased utility.
  • a lock according to the utility model for horizontally and vertically connecting boarding plates, especially into panels, directly or indirectly by inserts a thickness of which equals a thickness of boarding plates to be connected is characterized in that it consists of a slide having a shelf on which there is permanently mounted from above a pair of movable jaws, and from below said slide has permanently fastened a skid, of a guide having a pair of fixed jaws, forming a monolithic unit with side walls of the guide, and of a wedge fixing the position of the jaws being movable in relation to the guide of the slide.
  • a skid of the slide being mounted with rotation and sliding movement by means of a rivet in the guide from a side opposite to the pair of the fixed jaws, and said wedge being mounted by running perpendicularly through two openings in side walls of the guide and in the opening in the skid of the slide.
  • Said skid has a longitudinal opening from the side of the movable jaw, and slightly below at the side opposite to the movable jaws it has a longitudinal opening with corrugated edges, which determine a force with which a wedge presses against a slide and a guide through an opening located at the opposite end of a skid from a side of said rivet.
  • the wedge has on its surface from two sides longitudinal guiding elements having a corrugated form corresponding to a shape of a corrugated edge of the opening in the skid, and moreover at the second narrower end of the wedge there is mounted a stop protecting the wedge against sliding out from the guide of said lock, and at the second wider end it has double-sided recesses in its surface to decrease its weight.
  • longitudinal guiding elements having a corrugated form corresponding to a shape of a corrugated edge of the opening in the skid
  • a stop protecting the wedge against sliding out from the guide of said lock, and at the second wider end it has double-sided recesses in its surface to decrease its weight.
  • a simple structure of a lock according to the utility model establishes its advantage.
  • This lock for connecting boarding plates consists of three basic elements, which are so shaped and connected together in one unit that its reliable action is ensured.
  • a rigid movable compressing jaw is formed monolithically with a slidable slide, and another jaw forms a monolith with a guide. Fixing of a working position of jaws is ensured by a wedge having shaped surfaces on both sides provided with guiding elements creating forces clamping in the horizontal and vertical direction in such a way that the connected boarding plates adhere precisely and tightly one to another, and are adjusted one in relation to another when a lock is located at a bracing of the plates.
  • Both parts of the lock are connected together smoothly by introducing the wedge into a slot formed in the movable slide skid and in the guide, said wedge being protected against falling out of the guide. Thanks to a great distance between the guiding rivet and the wedge a transverse force created by an existing moment is small. Thanks to that a friction force created at the guiding planes is respectively small too. It increases the effectiveness when wedging the lock. Because individual parts are functionally connected together, the fact they are protected against falling out eliminates a possibility of losing some of them, what is probable in the building conditions. The structure of the lock is so ingenous that a part guiding the wedge is effectively protected against getting dirty. It is important for the effective operation of the lock in the hard building conditions.
