Technical Field

The invention relates to a metal roof clamp with a wedge-shaped tensioning structure.

Background

The metal roof system is in a roof form that a metal plate is used as a roof material and a structural layer and a waterproof layer are combined into a whole.

Single-bite short-standing systems have found considerable application in the construction industry as one of the structures and techniques for a multitude of mature metal roofing systems. The extended application of the core technology of the short stand-edge system with the single occlusion structure is as follows: wind resistance reinforcement, anti-skid snow blocking, anti-falling anchoring, external decoration, external photovoltaic, floodlight and the like all rely on a connection conversion clamp (hereinafter referred to as a clamp) of a single-occlusion structure short-standing system.

As shown in fig. 1, the system is a partial schematic view of a single-meshing-structure low-standing-edge system in the prior art, and includes two adjacent roof panels 1 and 2, the roof panels 1 and 2 respectively correspond to respective standing edges 11 and 22, a slidable sliding lock catch 4 is fastened between the standing edges 11 and 22, and the sliding lock catch 4 includes a lock tongue 41 and a base 42; the top end structure of the vertical edge 11, the lock tongue 41 and the top end structure of the vertical edge 22 form a single-meshing structure 3 of a single-meshing structure short vertical edge system at the position 3 in a mutual meshing mode; the sliding lock catch 4 is connected to the surface supporting structure 44 of the metal roof by a rivet 43; after the roof panel is installed, a sufficient installation gap b2 should be ensured between the vertical edge 11 and the vertical edge 22, and the roof panels 1 and 2 can clamp the lock tongue 41 and freely slide in the sliding groove of the base 42 along the length direction of the panel, so that the short vertical edge system with the single-engagement structure can keep sufficient thermal expansion damage resistance, and thus, the waterproof function and the service life of the roof can be ensured.

As shown in fig. 2, the single-engagement structure low-standing-edge fixture in the prior art generally uses two flaps (5, 6) of the fixture to respectively clamp the standing edges (11, 22) of two adjacent roof panels engaged together, wherein one flap 6 has enough structural space 62 to be free from the single-engagement structure 3 of the roof panels, and the two flaps (5, 6) of the fixture tightly clamp the standing edges (11, 22) of two adjacent roof panels by tightening the bolts 7, so as to achieve the working state of the single-engagement structure low-standing-edge fixture in the prior art. The existing short vertical edge clamp with a single occlusion structure has the following defects:

1. when the bolt group 7 is normally screwed, the installation gap b2 between the vertical edges (11, 22) of two adjacent plates tends to be infinitesimal, and the inherent thermal expansion damage resistance of the roofing system is seriously reduced or even eliminated;

2. if the fastening force of the bolt group 7 is insufficient, the clamp cannot obtain enough clamping force to generate friction force along the length direction of the roof panel, and the clamping is not firm enough and is easy to fall off;

3. if the mounting clearance b2 of the vertical edges (11, 22) of two adjacent plates is in a larger value, the clamp is clamped by the clamp, so that the vertical edges (11, 22) of the roof panel are possibly squeezed by the clamp to cause water-proof failure;

4. if the mounting gap b2 between two adjacent plates is at a large value, the expansion with heat and contraction with cold of the metal roof plate along the width direction of the plate are limited due to the clamping of the clamp, and the hidden trouble of roof plate pulling crack is generated;

5. the single-meshing-structure short-standing-edge metal roof system belongs to a surface-supported thin-plate structure, and the standing edges (11, 22) of the roof panel can neither bear heavy pressure in the direction vertical to the surface supporting structure 44 nor support the left-right swinging of external force, so that the existing clamping technology is extremely unstable.
