Clip fastening bracket and planar construction equipped therewith

A clip clamp for securing boards, each having first longitudinal grooves on each side, without screws or nails, onto support beams, each having second longitudinal grooves on each side, the support beams running at an angle to the boards longitudinally, to form a substructure or support structure, comprising:

• a base comprising a squared C-shaped profile and having a middle plate, from which two side plates extend at a right angle from edges of the middle plate;
• each of the side plates have a first lip at an end of each side plate, the side plate facing toward one another in a first direction, the first lips being configured to fit into the second longitudinal grooves in the support beams;
• and
• two board clamps extending from the middle plate in a second direction that is at an angle to the first direction, each board clamp having a clamping plate, each clamping plate having a second lip facing outward, the second lips facing away from one another, the second lips being configured to fit into the first longitudinal grooves in the boards, characterized in that:
• the clip clamp comprises a single piece of an elastic, resilient polymer;
• the first lips on the side plates and the second lips on the clamping plates all having a substantially rectangular cross section, and wherein the first lips on the side plates and the second lips on the clamping plates extend at right angles to one another;
• wherein the clip clamp is further configured to form a first substantially form-fitting connection with one of the support beams when the clip clamp is pushed onto the support beam by spreading the side plates apart until the first lips on the side plates engage the second longitudinal grooves of the support beam;
• and
• wherein the clip clamp is further configured to form a second substantially form-fitting connection with one of the boards to hold the board in place when the board clamps of the clip clamp are bent back to allow the second lip of one of the clamping plates of the clamp to engage the first longitudinal groove on a side of one of the boards and when the board clamps of a second, identical clip clamp on an adjacent support beam are bent back to allow the second lip of one of the clamping plates of the second clip clamp to engage the first longitudinal groove on an opposite side of the board.
