[0020] Embodiment 1

[0021] like Figure 1 As shown, a lightweight prestressed plate comprises a lightweight filling material 1, a prestressed baffle plate 2 and a panel 3. The lightweight filling material 1 is foamed concrete, which is used to ensure the compressive strength of the entire prestressed plate; the prestressed baffle plate 2 is made of galvanized angle iron, which is connected to the left and right ends of the lightweight filling material 1; the panel 3 is a steel plate or an aluminum face plate, which is connected to the front end of the lightweight filling material 1, and the panel 3 is vertically arranged between the left and right relatively parallel prestressed baffle plates 2; a plurality of tensioning cable members 4 are arranged in the lightweight filling material 1, and a plurality of connecting holes 6 are arranged on the prestressed baffle plate 2, and the connecting holes 6 are aligned with the tensioning cable members 4 one by one, and a locking head (not shown in the figure) is arranged in the connecting hole 6, which is connected and locked with the tensioning cable member 4 by the locking head, so that the prestressed baffle plate 2 is locked with the foamed concrete, which facilitates the enhancement of the tensile strength of the entire prestressed plate.

[0022] When installing wall panels in existing buildings, it is necessary to first fix the purlins on the structural members and then install the wall panels; however, due to the excellent compression and tensile properties of the prestressed panels, the overall strength and bearing capacity of the panels are strong, and they can be directly installed on the structural members without installing purlins. In this way, the prestressed panels can meet the "purlinless" requirements and have a wider range of uses.

[0023] In this embodiment, the tensioning cable member 4 is a prestressed steel bar or steel strand, and the lock head is a conventional anchor head or conventional part corresponding thereto. The connecting hole 6 is a tapered hole, and the structural shape of the lock head is adapted to the structural shape of the connecting hole 6; the tapered hole facilitates a tighter connection between the lock head and the tensioning cable member 4, or facilitates a tighter connection between the prestressed baffle plate 2 and the foamed concrete.

[0024] In this embodiment, there are three tensioning cable members 4 on the horizontal plane, which are equidistant from each other. Three tensioning cable members 4 form a group. There are several groups of tensioning cable members 4 in the vertical direction. The number of groups depends on the height size of the entire prestressed plate and other factors. The number and arrangement of tensioning cable members 4 and lock heads (or connecting holes 6) are adapted to each other.

[0025] In this embodiment, a whole prestressed plate, that is, a portion of lightweight filling material 1 (a plurality of tensioning cable members 4), two prestressed baffles 2, and a panel 3, is a unit; during construction, a plurality of units can be assembled and combined, which is more flexible to use and has a wider range of applications; at the same time, the bidirectional tensioning cable members 4 also change the limitation that traditional prestressed plates can only be made into one-way plates.

[0026] In this embodiment, the lightweight filling material 1 may also be made of lightweight materials other than foamed concrete, making full use of the compression and tension advantages of different materials to improve the use efficiency of the materials.

[0027] The beneficial effects of this embodiment are: the compressive strength of the entire panel is guaranteed by the foamed concrete, and the tensile performance of the entire panel is improved by the tensioning cable 4. In this way, when this prestressed panel is used in construction, it can greatly increase the overall strength and bearing capacity of the lightweight material panel, and has a wide range of uses, saving more money and energy for the society. By adopting lightweight materials, the entire panel has a light weight, reducing the constant load of the building design, saving materials for beams and columns, and improving the economy of the building; by using bidirectional prestressed steel bars or steel strands, the bidirectional bearing capacity of the lightweight panel is improved, and at the same time, the limitation that the traditional prestressed panel can only be a one-way panel is changed.

[0028] Embodiment 2

[0029] The difference between this embodiment and the first embodiment is that a plurality of longitudinally arranged reserved holes 5 are further provided in the lightweight filling material 1 , and the reserved holes 5 are vertically arranged above and below the tensioning cable member 4 .

[0030] In this embodiment, there are three reserved holes 5 on the horizontal plane, which are equidistant from each other, and three reserved holes 5 form a group. There are several groups of reserved holes 5 in the vertical direction, and the number of groups depends on factors such as the height size of the entire prestressed plate.

[0031] In this embodiment, the reserved holes 5 can be applied at the construction site; corresponding holes for connection can be set on the panel 3 at positions corresponding to the reserved holes 5. The reserved holes 5 are convenient for meeting the roof requirements and facilitating the longitudinal assembly and connection of the entire panel unit.

[0032] The beneficial effect of this embodiment is that by setting the reserved holes 5, the roof requirements can be met, several prestressed panel units can be longitudinally assembled and connected to expand the scope of use, and the stability of the panel structure can also be enhanced.
