Description

Technical Field

[0001] The utility model relates to the technical field of roof sandwich panels, in particular to a connecting structure for a lock-type roof sandwich panel. Background Technique

[0002] With the continuous expansion of the construction scale of industrial buildings, as a green building material, the metal-faced sandwich panel has many advantages such as excellent heat insulation performance and convenient installation. Therefore, the metal-faced sandwich panel is more and more widely used in the roof system of industrial factories. When splicing the sandwich panels, it is usually necessary to pre-set a connecting structure to facilitate on-site assembly by workers;

[0003] The authorized publication number CN216446359U discloses a connecting structure for a lock-type roof sandwich panel. This device mainly splices the first roof sandwich panel and the second roof sandwich panel together through the buckling of the bent edge and the bent buckle edge, which can prevent raindrops from entering the roof sandwich panel; at the same time, a closing pliers can be used to clamp the bent edge and the bent buckle edge to achieve a better buckling effect; in addition, by passing a fastener through the installation side plate of the second roof sandwich panel, the fastener does not contact the core material when fixing the second roof sandwich panel, which can effectively avoid damage to the fastener due to the internal stress generated by the thermal expansion and contraction of the sandwich panel. However, when the connecting structure is actually used, there are still the following defects:

[0004] The above patent mainly uses the buckling of the bent buckle edge to splice the first roof sandwich panel and the second roof sandwich panel together to achieve the function of preventing raindrops from entering the roof sandwich panel. However, the fasteners used in this buckling structure are arranged outside the structure, which is easy to cause the fastening structure to be eroded, corroded and worn by the external environment for a long time, affecting the secondary disassembly and recycling of the fasteners, resulting in the inability to reuse the sandwich panel, and increasing the limitations of the connecting structure.

The bearing seat 12 can also drive the two sets of movable rods 13 to work together while rising and falling, so that the movable rods 13 can respectively drive the guide tube 15 and the L-shaped splicing rod 16 to expand or retract, so as to facilitate corresponding operations according to the fixing and disassembly of the connection structure.

[0026] Working principle: In the bite-type roof sandwich panel connection structure;

[0027] When splicing and assembling the lock-type roof sandwich panel, the splicing blocks 5 and splicing grooves 6 can be preset on the sides of the first roof sandwich panel 1 and the second roof sandwich panel 2. So that during actual splicing, by engaging the splicing groove 6 on the side of the first roof sandwich panel 1 with the splicing block 5 on the side of the second roof sandwich panel 2, the splicing accuracy and efficiency of the first roof sandwich panel 1 and the second roof sandwich panel 2 can be improved. After the first roof sandwich panel 1 and the second roof sandwich panel 2 are fitted, by rotating the adjusting bolt 10 to drive the convex rod to rotate in the bearing seat 12, the bearing seat 12 is urged to rise stably. At the same time, the two groups of movable rods 13 are linked with the conduit 15 structure, so that the two groups of movable rods 13 drive the conduit 15 to open outwards under the limit guidance of the guide rod 14. At this time, the movement of the two groups of conduits 15 drives the two groups of L-shaped splicing rods 16 to be inserted into the splicing pipe 17, so as to realize the hidden snap-fitting splicing function of the first roof sandwich panel 1 and the second roof sandwich panel 2. After reaching the maximum snap-fitting position, the snap plate at the end face of the notch 3 is unfolded, and the positioning bolt 19 is driven into the notch 3, so that the positioning bolt 19 extends into the notch 3 and the splicing pipe 17 and is threadedly connected with the L-shaped splicing rod 16, realizing the fixed locking function of the hidden splicing structure. With the fixation of this connection structure, it is not only convenient for secondary disassembly and assembly, but also has a better protection effect, avoiding the influence of the external environment on the fasteners.
