Description

Technical Field

[0001] The utility model relates to the technical field of composite wall panels, in particular to an assembled autoclaved aerated concrete exterior wall insulation board. Background Art

[0002] Existing integrated composite wall panels generally have an insulation board attached to the outside of the autoclaved aerated concrete board, and a mortar layer applied to the outside of the insulation board to achieve the insulation effect. In order to prevent separation between the insulation board and the autoclaved aerated concrete board, plastic rivets are generally driven into the mortar layer from the outside to connect to the autoclaved aerated concrete board, thereby realizing the connection of the three-layer structure.

[0003] However, as the thickness of the existing insulation layer and mortar layer increases, if they are simply connected by plastic anchors, the pull-out strength is insufficient, and long-term use may easily lead to separation between the insulation board and the autoclaved aerated concrete board.

[0021] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0022] like Figures 1 to 6As shown, the present invention is an assembled autoclaved aerated concrete exterior wall insulation board, comprising an autoclaved aerated concrete board 1, an insulation board 2, and a mortar layer 3, which are laminated in sequence. The insulation board is an SXPS insulation board or an XPS insulation board, and the mortar layer 3 is a protective layer of polystyrene particles. During processing, the mortar layer 3 is generally applied to the insulation board 2 first, and then connected to the autoclaved aerated concrete board 1. The autoclaved aerated concrete board 1, the insulation board 2, and the mortar layer 3 are of the same size. Generally, the thickness of the autoclaved aerated concrete board 1 is greater than that of the insulation board 2, and the thickness of the insulation board 2 is greater than that of the mortar layer 3.

[0023] It also includes multiple connection components 4, which are arranged in 3-8 rows in the length direction of the insulation board and 1-3 rows in the width direction of the insulation board, so as to achieve overall connection.

[0024] like Figure 4 As shown, the connecting assembly 4 includes a connecting rod 41 that passes through the autoclaved aerated concrete board 1, the insulation board 2 and the mortar layer 3. The connecting rod 41 is a screw. One end of the connecting rod 41 is fixedly connected to a connecting end plate 42. The connecting end plate 42 is located on one side of the mortar layer 3, and an end plate countersunk hole 43 for accommodating the connecting end plate 42 is opened on the outside of the mortar layer 3. Of course, the end plate countersunk hole 43 may not be set on the outside of the mortar layer 3, and the connecting end plate 42 is attached to the outer side of the mortar layer 3.

[0025] In this embodiment, the connecting end plate 42 is a rectangular plate, and the end plate countersunk hole 43 is a rectangular countersunk hole, thereby preventing the connecting rod 41 from rotating.

[0026] Of course, the connecting end plate 42 may also be a circular plate, and the end plate countersunk hole 43 may also be a circular countersunk hole.

[0027] The other end of the connecting rod 41 is threadedly connected to a nut 44. A nut countersunk hole 46 is formed on the outside of the autoclaved aerated concrete panel 1 to accommodate the nut 44. A washer 45 is provided between the nut 44 and the bottom of the nut countersunk hole 46, so that both the nut 44 and the washer 45 are located in the nut countersunk hole 46. In this embodiment, the nut countersunk hole 46 is a circular countersunk hole.

[0028] In order to achieve the fixation of both ends of the insulation board when it is installed vertically, Figure 5 As shown, mounting components 5 are installed at both ends of the autoclaved aerated concrete panel 1. The mounting components 5 include a mounting sleeve 51 passing through the autoclaved aerated concrete panel 1 and a mounting plate 54 attached to the outside of the autoclaved aerated concrete panel 1. One end of the mounting sleeve 51 is fixedly connected to a sleeve end plate 52 located between the autoclaved aerated concrete panel 1 and the insulation panel 2. The other end of the mounting sleeve 51 is threadedly connected to a bolt 53 for pressing the mounting plate 54. By tightening the bolt 53, the mounting plate 54 can be pressed against the outside of the autoclaved aerated concrete panel 1. A rectangular sink for accommodating the mounting plate 54 is opened on the outside of the autoclaved aerated concrete panel 1 in this embodiment.

[0029] The mounting plate 54 is provided with a mounting hole 56 for the bolt 53 to pass through. The mounting hole 56 is a long hole extending along the length direction of the autoclaved aerated concrete panel 1 .

[0030] The mounting plate 54 is fixed with a bent portion 55. Figure 6 As shown, the mounting plate 54 and the bent portion 55 form an L-shaped plate, which is an integrally bent structure.

[0031] The bent portion 55 is provided with an external connection hole 57 . The external connection hole 57 is a long hole extending along the width direction of the autoclaved aerated concrete panel 1 .

[0032] The use method of this utility model:

[0033] During processing, the autoclaved aerated concrete panel 1 and insulation panel 2 of the same size are first machined. A mortar layer 3 is then added to one side of the insulation panel 2. The installation sleeve 51 is then passed through the panel 1, with the sleeve end plate 52 positioned between the panels 1 and 2. The other side of the insulation panel 2 is then bonded to the autoclaved aerated concrete panel 1. Once completed, the semi-finished product is machined with connecting rod holes, end plate countersunk holes 43, and nut countersunk holes 46. Multiple connecting assemblies 4 are then installed to connect the three layers and prevent separation.

[0034] During installation, the insulation board is placed vertically, and the upper and lower ends are connected to the mounting plates 54 . The bent portion 55 on the mounting plate 54 is connected to the upper beam and the lower beam by bolts, thereby fixing the insulation board.

[0035] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that the changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
