Description

Technical Field

[0001] This utility model relates to a wall panel, and more specifically, to a prefabricated sandwich insulated wall panel. Background Technology

[0002] Precast wall panels with built-in insulation layers have weak bonding strength between the insulation layer and the concrete layer due to direct contact, making them prone to separation during use. This not only affects building construction but also poses safety hazards, resulting in poor overall performance. Therefore, this utility model proposes a precast sandwich insulation wall panel. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a prefabricated sandwich insulation wall panel with high connection strength and safe and reliable use.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to a prefabricated sandwich insulated wall panel, including a metal keel plate. The upper and lower ends of the metal keel plate are respectively pressed and formed with cylindrical protrusions. The protrusions extend vertically and are hollow inside. The top of the protrusions is provided with a casting hole to connect the interior with the outside. The upper and lower ends of the metal keel plate are also attached with foam cotton boards with a thickness not greater than the height of the protrusions. The foam cotton boards are provided with mating holes for the protrusions to be inserted. The end of the foam cotton board facing away from the metal keel plate is provided with a concrete casting layer. The protrusions extending out of the foam cotton board are embedded in the concrete casting layer.

[0005] The present invention is further configured such that the diameter of the casting hole is smaller than the inner diameter of the protrusion, and the orifice of the casting hole is provided with toothed grooves.

[0006] The present invention is further configured such that the protrusions are arranged in a rectangular array on the metal keel plate.

[0007] The present invention is further configured such that the thickness of the foam board is less than the height of the protrusion.

[0008] The present invention is further configured such that the metal keel plate is made of stainless steel.

[0009] In summary, this utility model has the following beneficial effects:

[0010] 1. The end faces of the foam board and the metal keel board, as well as the outer peripheral surfaces of the protrusions, are connected to increase the bonding area, thereby making the connection more reliable.

[0011] 2. The concrete pouring layer not only connects with the foam board, but also significantly increases the bonding area between the concrete pouring layer and the end face and inner circumference of the protrusion through the added protrusion, thus making the connection more reliable.

[0012] 3. The concrete poured through the pouring hole and into the protrusion can simultaneously connect the concrete pouring layer on one side and the foam board on the other side, making the overall connection of the wall panel reliable. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See Figure 1 and Figure 2 As shown, the prefabricated sandwich insulated wall panel involved in this embodiment includes a metal keel plate 1. The upper and lower ends of the metal keel plate 1 are respectively pressed into cylindrical protrusions 2, which extend vertically. The interior of the protrusions 2 is hollow. The top of the protrusions 2 is provided with a casting hole 3 to connect the interior with the outside. The upper and lower ends of the metal keel plate 1 are also attached with foam cotton boards 4, which are thinner than the height of the protrusions. The foam cotton boards 4 are provided with mating holes 5 for the protrusions to be inserted. The end of the foam cotton board 4 facing away from the metal keel plate is provided with a concrete pouring layer 6. The protrusions 2 extending out of the foam cotton board 4 are embedded in the concrete pouring layer 6.

[0019] Furthermore, the protrusions 2 are arranged in a rectangular array on the metal keel plate 1.

[0020] Furthermore, the metal keel plate 1 is made of stainless steel.

[0021] In this embodiment, a metal keel plate 1 is embedded in the insulation wall panel. The surface of the metal keel plate 1 is arranged with many vertically extending protrusions 2. The protrusions 2 penetrate the foam board 4 and can further connect with the concrete pouring layer 6. By adding adhesive at the connection between the protrusions 2 and the foam board 4, and at the connection between the metal keel plate 1 and the foam board 4, the connection strength between the foam board 4 and the metal keel plate 1 can be greatly improved.

[0022] Furthermore, since the two ends of the protrusion 2 are connected, the poured concrete also serves as a connection between the two ends, which can simultaneously connect the concrete pouring layer 6 on one side and the foamed cotton board 4 on the other side, further preventing the insulation wall panel from separating as a whole.

[0023] The protrusion 2 extending from the foam board 4 is embedded in the concrete pouring layer 6, which can also increase the contact area between the two, thereby achieving the effect of improving the connection strength.

[0024] Example 2

[0025] See Figure 1 and Figure 2 As shown, the prefabricated sandwich insulated wall panel involved in this embodiment is further configured, based on embodiment 1, that the diameter of the casting hole 3 is smaller than the inner diameter of the protrusion 2, and the opening of the casting hole 3 is surrounded by toothed grooves 7.

[0026] In this embodiment, the arrangement of the toothed grooves 7 extends the perimeter of the pouring hole 3, thereby increasing the contact area with the concrete and improving the connection strength.

[0027] The precast sandwich insulated wall panel of this utility model has a foamed cotton board that is connected to the end face of the metal keel board and the outer peripheral surface of the protrusion, increasing the bonding area and thus making the connection more reliable. The concrete pouring layer is not only connected to the foamed cotton board, but also the added protrusion significantly increases the bonding area between the concrete pouring layer and the end face and inner peripheral surface of the protrusion, thus making the connection more reliable. Furthermore, the concrete poured through the pouring hole and into the protrusion can simultaneously connect the concrete pouring layer on one side and the foamed cotton board on the other side, making the overall connection of the wall panel reliable, the overall function complete, and the practicality strong.
