Technical Field

[0001] The invention relates to the technical field of wall panel connection, in particular to a connection device for assembled thermal insulation wall panels. Background Art

[0002] Insulation wall panels are simply boards used for insulation of buildings. They are made of polystyrene resin as raw material, other raw and auxiliary materials and polymers, which are heated and mixed while injecting catalysts, and then extruded and pressed to form hard foam plastic boards. They have moisture-proof and waterproof properties, and can reduce the thickness of the building's external protective structure, thereby increasing the indoor usable area. Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories, where building components and accessories, such as floor slabs, wall panels, stairs, balconies, etc., are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0018] See also Figure 5 As shown, the thermal insulation wall panel 1 is provided with a circular groove 14 for embedding the three-in-one eccentric wheel 13 corresponding to the three-in-one eccentric wheel 13, and a pressure ring 15 is fixedly connected to the top opening of the circular groove 14.

[0023] A movable and detachable extension block 19 is provided at the end of the connecting horizontal bar 2. During cross-joining, the extension block 19 can be used to fill the assembly gap of the connecting horizontal bar 2, and the connecting plate 20 can be used to lock and fix it to avoid large-area holes.

[0024] The working principle of the patented invention is: When in use, first place the connecting cross bar 2 corresponding to the cross, and the corresponding positioning rod 18 passes through the upper extension block 19 in the notch 17 at the end of the connecting cross bar 2, and the extension block 19 is connected through the connecting plate 20. When connecting, the fixing bolt 22 passes through the fixing hole 21 and then tightens the nut 23 to lock and fix it, so that multiple connecting cross bars 2 are connected and combined with each other. At this time, the insulation wall panel 1 is placed between the connecting cross bars 2.

[0026] The present invention uses a three-in-one eccentric wheel to cooperate with a connecting ball head to tighten the corresponding threaded rod, so that the connecting horizontal bar and the thermal insulation wall panel form a connection and fixing effect. At the same time, the worm gear is driven by the worm, so that the threaded rod is driven to move along the sliding direction of the guide groove and the guide block through the threaded sleeve, so that the threaded rod can move freely in and out of the movable cavity. Therefore, when the thermal insulation wall panel is disassembled and adjusted, the threaded rods on the four sides of the thermal insulation wall panel can be contracted, so that the threaded rod is detached from the thermal insulation wall panel, which is convenient for individual thermal insulation wall panels to be dismantled separately after multiple thermal insulation wall panels are spliced ​​and assembled.

[0027] A movable and detachable extension block is provided at the end of the connecting horizontal bar. During cross-joining, the extension block can be used to fill the assembly gap of the connecting horizontal bar, and locked and fixed with the connecting plate to avoid large-area holes. At the same time, the extension block can be removed at the edge position of the insulation wall panel connection, thereby effectively avoiding edge bulging and facilitating the assembled insulation wall panel to fit the edge wall.
