[0001] The utility model belongs to the technical field of building construction, and more specifically relates to a connection structure of an external plain brick wall and an AAC external wall board. Background Art
[0002] In architectural design, reinforced concrete structural columns, ring beams and tie bars are generally used to ensure the overall stability and safety of the infill wall during normal use and under earthquake and wind loads. Due to policy requirements such as thermal insulation, energy saving, and assembly, the exterior walls of buildings generally use lightweight thermal insulation blocks, lightweight thermal insulation strip wall panels, etc. In order to achieve the effect of an external exposed brick wall, an external exposed brick wall is built on the outside of the thermal insulation exterior wall.
[0003] At present, the most common method of connecting masonry infill walls with the main structure is to use reinforced concrete structural columns, ring beams and tie bars. However, the traditional method of strengthening structural columns and ring beams is not suitable for connecting and fixing external plain brick walls. The use of ring beams and structural columns that are thinner than the thickness of the external plain brick walls combined with the construction method of building the walls first and then pouring the structural columns will increase the construction period and cost.
[0004] At present, with the promotion of prefabricated buildings, traditional structural columns and ring beams are mostly replaced by autoclaved lightweight sand aerated concrete strip board exterior walls (hereinafter referred to as AAC exterior wall panels). Now there is a need for a connection structure that can connect the AAC exterior wall panels with the outer side-mounted or hollow-mounted external plain brick walls to ensure the overall performance and wind and earthquake resistance of the external plain brick walls.

[0023] Compared with the prior art, the connection structure of the external plain brick wall and the AAC external wall panel provided by the utility model forms a tie-net structure between the AAC external wall panel 8 and the external plain brick wall 9 by installing the embedded parts 6, the vertical positioning parts 1 and the horizontal extension parts 4 connected in sequence in the mortar joints between the AAC external wall panel 8 and the external plain brick wall 9, and then the external plain brick wall 9 and the AAC external wall panel 8 are connected as a whole through the combination of the mortar joints and the connection structure, so as to achieve the purpose of ensuring the overall performance and wind and earthquake resistance of the external plain brick wall 9. At the same time, because the connection structure is hidden in the mortar joints, the architectural appearance effect of the external plain brick wall 9 is also ensured.

The longitudinal extension member 5 is vertically connected to the free end of the transverse extension member 4 by welding or other connection methods, and the longitudinal extension member 5 is located in the horizontal mortar joint between two layers of the external plain brick wall 9.
[0027] The longitudinal extension member 5 and the transverse extension member 4 are both horizontally arranged plate-like structures. The thickness of the longitudinal extension member 5 is less than the thickness of the horizontal mortar joint, and the width of the longitudinal extension member 5 is less than the width of the external plain brick wall 9. Optionally, the width of the transverse extension member 4 is 20 mm and the thickness is 3 mm; the width of the longitudinal extension member 5 is 20 mm and the thickness is 3 mm. Both the transverse extension member 4 and the longitudinal extension member 5 need to avoid the hollowing out of the external plain brick wall 9. Optionally, the longitudinal extension member 5 coincides with the center line of the external plain brick wall 9.
[0028] In some possible embodiments, see Figure 1 The vertical positioning member 1 is provided with a plurality of connection parts at intervals along the length direction, and the connection parts are used to connect the fixed ends of the transverse extension members 4; a fixing part is provided between two adjacent connection parts, and the fixing part is used to connect the embedded parts 6.

The connecting part is used to connect the fixed end of the horizontal extension member 4; the fixing part is used to connect the free end of the embedded member 6.
[0030] The fixing portion is provided with a fixing hole 7; the embedded part 6 is an anchor rod, and the anchor rod is matched with the fixing hole 7 for anchoring connection.
[0031] The anchor rod end of the embedded part 6 extends out from the fixing hole 7 and is fixedly connected to the vertical positioning plate by means of a nut and a connecting plate. In order to adapt to the position error of the anchor rod, the fixing hole 7 adopts an oblong bolt hole. The distance between two adjacent fixing holes 7 is ≤600mm.
[0032] The vertical positioning member 1 is also vertically connected to the horizontal positioning member 2, and the horizontal positioning member 2 is located in the vertical mortar joint between the AAC exterior wall panel 8 and the exterior plain brick wall 9. The horizontal positioning member 2 is vertically connected to the vertical positioning member 1, and the length direction of the horizontal positioning member 2 is consistent with the length direction of the wall. The thickness direction of the horizontal positioning member 2 is consistent with the thickness direction of the wall, and the thickness direction of the vertical positioning member 1 is consistent with the thickness direction of the wall.

[0035] The horizontal positioning member 2 is a steel plate with a width of 20 mm and a thickness of 4 mm. The horizontal positioning plate needs to be disconnected when encountering the window opening, and should avoid the hollowing out of the external brick wall 9.

Then, through the combination of the mortar joint and the tie steel plate mesh, the external plain brick wall 9 and the AAC external wall panel 8 are connected as a whole, so as to achieve the purpose of ensuring the overall performance and wind and earthquake resistance of the external plain brick wall 9. At the same time, because the steel plate is hidden in the mortar joint, the architectural appearance of the plain brick wall is also guaranteed.
[0040] The connection structure between the external plain brick wall and the AAC external wall panel provided by the utility model uses a steel plate with a relatively small thickness to form a three-dimensional connection system between the external plain brick wall 9 and the AAC external wall panel 8, achieving the effect of traditional concrete structural columns and ring beams, thereby achieving the effects of accelerating the construction period, simplifying the construction process, and reducing costs.
