Description

Technical Field

[0001] The utility model relates to the field of sandwich panels, in particular to a rock wool thermal insulation integrated sandwich panel bottom panel connection structure. Background Art

[0002] The traditional process of rock wool insulation integrated board is to bond the rock wool insulation strip in the middle of the bottom panel with a composite adhesive on both sides to form a whole. When the insulation core material is thin, this process is installed on the exterior wall of the building through a bonding and anchoring process. The connection structure between the rock wool insulation layer and the bottom surface layer on both sides has the following defects:

[0003] 1. There are about 9 to 10 40mm*40mm U-shaped bottom panel connectors pre-installed inside per square meter. The placement of the U-shaped parts seriously damages the thermal insulation function of the product and artificially increases many cold and hot bridges.

[0004] 2. The U-shaped fasteners connected by the panel core-pulling anchors are sunk into the 8mm thick panel, with a depth of about 2mm from the top surface of the panel. The height of the core-pulling anchors themselves is 3-4mm, and the effective anchoring part of the remaining plate thickness is only 2-3mm thick. The connection strength is too thin, and it will slip off at the slightest external force, posing a safety hazard.

[0005] 3. If the putty repair on the top of the countersunk core anchor slips off, it will become loose and crack, forming a source of water seepage, while water seepage is strictly prohibited on the exterior walls of buildings. Utility Model Content

[0006] The utility model aims to solve the problem that the built-in U-shaped bottom panel connector existing in the background technology destroys the thermal insulation function and the connection strength is insufficient, and water seepage may occur when the anchor nail slips off, and proposes a rock wool insulation integrated sandwich panel bottom panel connection structure.

[0007] The technical solution of the utility model: a rock wool insulation integrated sandwich panel bottom panel connection structure, including a rock wool layer and bottom panels on both sides of the rock wool layer; also includes a screw that penetrates the rock wool layer, with a countersunk head and a fixing piece respectively arranged at both ends of the screw, one of the bottom panels is provided with a countersunk hole that cooperates with the countersunk head, and the outer side surface of the other bottom panel is in contact with the fixing piece.

[0008] Preferably, the countersunk head is an inverted cone countersunk head, the countersunk hole is a tapered hole, the fixing piece is a metal plate, the screw rod is a self-tapping screw with a tail drill, and the tail of the screw rod is self-tapping through the metal plate to flatten the head of the tail drill.

[0009] Preferably, the countersunk head is a disc countersunk head, the countersunk hole is a disc countersunk head, the screw rod is a tail drill self-tapping screw, and the tail of the screw rod is self-tapping through the metal plate to flatten the tail drill nail head.

[0010] Preferably, the countersunk head is a disc countersunk head, the countersunk hole is a disc countersunk head, and the fixing piece is a nut, which is screwed on the screw rod and abuts against the bottom panel.

[0011] Preferably, the countersunk head is an inverted cone countersunk head, the countersunk hole is a tapered hole, and the fixing piece is a nut, which is screwed on the screw rod and abuts against the bottom panel.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects: the U-shaped part is eliminated, and a through-type straight anchor is used to form the thermal insulation core material as a whole, eliminating the influence of artificially created cold and hot bridges on the thermal insulation function, and the connection strength is higher, and the possibility of the countersunk bolt slipping is further reduced, thereby ensuring the waterproof effect.
