Description

Technical Field

[0001] The present application relates to the technical field of composite panels, and in particular to an assembled composite panel made of cement-based fiber material. Background Art

[0002] In the field of prefabricated buildings, cement-based fiber composite panels have attracted much attention for their unique structure and performance. This type of panel consists of two major parts: a prefabricated base plate and a steel truss, and their combination provides excellent bearing capacity and stability for the building structure.

[0003] The prefabricated base plate is used as the base layer of the laminated board. It uses sustainable agricultural and forestry waste plant fibers such as cement and straw, as well as functionalized additives and specially made expanded resin particles as raw materials. These materials are stirred and solidified in the mold with water to form a solid structure of the prefabricated base plate.

[0004] The steel truss constitutes the superstructure of the composite plate, which is connected by the upper chord steel bars, lower chord steel bars and web bars on both sides through precise welding technology. This design not only enhances the overall strength and rigidity of the composite plate, but also ensures that it can safely withstand various service loads.

[0005] In the traditional manufacturing process of welded composite slabs, the prefabricated base plate and the steel truss are independently manufactured and formed. Subsequently, a fixed support is set on the prefabricated base plate, and the steel truss is connected to the support of the prefabricated base plate by manual welding to achieve fixation between the two.

[0006] However, since composite plates have strict requirements on welding quality, manual welding methods often cannot ensure the consistency and reliability of welding, which may lead to welding quality problems and affect the overall performance and safety of the composite plates. Utility Model Content

[0007] In order to improve the quality problems existing in manual welding, the present application provides an assembled composite panel made of cement-based fiber material.

[0008] The present application provides a cement-based fiber-based assembled composite board, which adopts the following technical solution:

[0009] A prefabricated composite plate of cement-based fiber material, comprising a prefabricated base plate and a steel truss, wherein the steel truss comprises an upper chord steel bar, a lower chord steel bar and web steel bars on both sides, and also comprises a support, wherein the support is fixed to the prefabricated base plate and used to connect the prefabricated base plate and the steel truss; a locking column is rotatably connected to the support, and the locking column is provided with a receiving groove for accommodating the steel bar, and the receiving groove extends along the axial direction of the locking column; the support is also provided with a locking component for fixing the locking column when the locking column is rotated to close the notch of the receiving groove.

[0010] By adopting the above technical solution, the mechanical connection between the prefabricated bottom plate and the steel truss is realized through the design of the lock column on the support, replacing the traditional manual welding method. The receiving groove of the lock column can easily accommodate the steel bar, and the lock column is fixed by the locking assembly to ensure the stability and reliability of the connection, thereby improving the overall performance and safety of the composite plate.

[0011] Optionally, the support includes a web and two wing plates symmetrically fixed on the web, the wing plates are provided with an arc groove for accommodating the lock column, the notch of the arc groove is smaller than the diameter of the lock column, so that the lock column will not fall out of the notch of the arc groove in the vertical direction.

[0012] By adopting the above technical solution, the design of the arc groove limits the movement of the lock column in the vertical direction, ensuring that the lock column will not fall off the support, thereby enhancing the stability of the connection. At the same time, the arc groove also provides a guide for the rotation of the lock column, making the installation process smoother.

[0013] Optionally, the locking assembly includes a hoop, which includes a hoop plate and connecting pieces fixed at both ends of the hoop plate; the two connecting pieces are fixed to the support by bolts, so that the hoop plate presses and fixes the locking column in the circular arc groove.

[0014] By adopting the above technical solution, the design of the clamp is fixed to the support by bolts, which can tightly press the locking column to prevent it from loosening or rotating in the arc groove, further enhancing the stability and safety of the connection.

[0015] Optionally, a positioning block is fixed on one side of the hoop plate that contacts the lock column, and a positioning groove for the positioning block to be inserted into is formed on the lock column; the positioning groove and the accommodating groove are located on the same diameter line of the lock column.

[0016] By adopting the above technical solution and designing the positioning block and the positioning groove, the accurate positioning of the locking column during the rotation process is ensured, thereby improving the accuracy and reliability of the connection.

[0017] Optionally, a limiting block is fixed to the bottom of the circular arc groove, and an annular groove adapted to the limiting block is formed on the outer peripheral side of the lock column.

[0018] By adopting the above technical solution, the limit block prevents the lock column from shifting in the circular arc groove.

[0019] Optionally, the locking assembly further comprises a top block fixed on the web for supporting the steel bar, and under the locking action of the clamp, the top block is used to press the steel bar tightly into the accommodating groove.

[0020] By adopting the above technical solution, the two hoops and the top block in the middle work together to achieve comprehensive locking of the steel bars and enhance the stability of the connection.

[0021] Optionally, each group of hoops for locking the locking column is provided with two hoops, and the two hoops are located at both ends of the locking column.

[0022] By adopting the above technical solution, two hoops are arranged at both ends of the locking column, so that the steel bar can be locked in the receiving groove more stably.

[0023] Optionally, the outer contour of the arc groove is supported on the prefabricated base plate.

[0024] By adopting the above technical solution, the contact area between the support and the prefabricated bottom plate is increased, and the bearing capacity and connection stability of the support are improved.

[0025] In summary, the present application includes at least one of the following beneficial effects:

[0026] 1. The mechanical connection method of the support, locking column and locking components (such as clamps) replaces the traditional manual welding, which not only improves the overall performance of the composite plate, but also significantly enhances the stability and safety of the connection;

[0027] 2. The coordinated design of the positioning block and the positioning groove, as well as the guiding effect of the arc groove on the lock cylinder, ensure the precise positioning of the lock cylinder during the rotation process, greatly improving the accuracy and efficiency of installation.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] The present application discloses a prefabricated composite board made of cement-based fiber material. Figure 1 , 2The assembled composite slab includes a prefabricated bottom plate 1, a steel truss 2 and a support 3. The prefabricated bottom plate 1 can be made of sustainable agricultural and forestry waste plant fibers such as cement and straw, as well as functionalized additives and specially prepared expanded resin particles as raw materials, and a solid structure is formed in a mold through a process of adding water, stirring and solidifying. The steel truss 2 includes an upper chord steel bar, a lower chord steel bar and web bars on both sides. The support 3 is used to connect the prefabricated bottom plate 1 and the steel truss 2.

[0035] Reference Figure 1 , 2 The support 3 is fixed to the prefabricated bottom plate 1 by bolts, and a plurality of supports 3 are arranged at equal intervals on the prefabricated bottom plate 1 along the length direction of the steel bar truss 2. In other embodiments, the support 3 may also be fixed in other ways, and this embodiment does not limit the fixing method of the support 3. A locking column 31 is rotatably connected to the support 3, and the locking column 31 is provided with a receiving groove 311 for receiving the steel bar, and the receiving groove 311 extends along the axial direction of the locking column 31.

[0036] Specifically, refer to Figure 2 , 3 The support 3 includes a web 33 and two wing plates 32 symmetrically fixed on the web 33. The wing plates 32 are provided with an arc groove 321. The lock post 31 is rotatably connected in the arc groove 321. The notch of the arc groove 321 is smaller than the diameter of the lock post 31 to prevent the lock post 31 from coming out in the vertical direction. In this embodiment, the lock post 31 can be installed by squeezing into the arc groove 321. In order to fix the lock post 31, a locking assembly is provided on the support 3. The locking assembly is used to fix the lock post 31 when the lock post 31 rotates until the notch of the receiving groove 311 enters the arc groove 321 and is closed.

[0037] Reference Figure 2 , 3 The locking assembly includes a hoop 34, which is composed of a hoop plate 341 and connecting pieces 342 fixed at both ends of the hoop plate 341. The two connecting pieces 342 are fixed to the wing plate 32 of the support 3 by bolts, so that the hoop plate 341 is tightly pressed against the locking column 31 and fixed in the circular arc groove 321.

[0038] In order to ensure the accurate positioning of the lock column 31, a positioning block 3411 is fixed on the side of the hoop plate 341 that contacts the lock column 31, and a positioning groove 312 is provided on the lock column 31 for the positioning block 3411 to be inserted into. The positioning groove 312 and the receiving groove 311 are located on the same diameter line of the lock column 31. That is, the notch position of the positioning groove 312 is opposite to the notch position of the receiving groove 311. When the notch of the receiving groove 311 is rotated to align with the bottom of the arc rotating groove 321, the positioning groove 312 is outside the arc rotating groove 321.

[0039] Reference Figure 2 , 3A limiting block 322 is fixed to the bottom of the arc groove 321, and an annular groove 313 adapted to the limiting block 322 is provided on the outer circumference of the lock column 31. The annular groove 313 is located in the middle of the lock column 31. With the cooperation of the limiting block 322 and the annular groove 313, the axial sliding of the lock column 31 can be limited.

[0040] Reference Figure 2 , 3 The locking assembly also includes a top block 331 fixed on the web 33 for supporting the steel bar. The height of the top block 331 can exert an upward extrusion force on the steel bar when the steel bar is locked in the locking column 31, so that under the locking action of the clamp 34, the top block 331 tightly presses the steel bar in the receiving groove 311, thereby enhancing the connection strength between the steel bar and the locking column 31. At the same time, under the cooperation of the locking column 31 of the two wing plates 32 and the clamp 34, and the joint action of the top block 331 in the middle, the locking structure of pressing down the two ends of the steel bar and pushing up in the middle is realized, thereby realizing the comprehensive locking of the steel bar. In other embodiments, when the height of the top block 331 is not enough to lift the steel bar, a wedge block or a threaded lifting nut can be added to replace the top block 331 to lift the steel bar.

[0041] Reference Figure 3 , 4 Each set of clamps 34 for locking the locking column 31 is provided with two, which are respectively located at both ends of the locking column 31 to more evenly distribute the locking force. The outer contour of the arc groove 321 is supported on the prefabricated bottom plate 1, which increases the contact area between the support 3 and the prefabricated bottom plate 1 and improves the bearing capacity and connection stability of the support 3.

[0042] The implementation principle of the assembled composite board made of cement-based fiber material in the embodiment of the present application is as follows:

[0043] First, rotate the lock column 31 until the notch of the receiving groove 311 faces outward; secondly, when the steel bar rests on the top block 331 and is stuck in the receiving groove 311, rotate the lock column 31 so that the notch of the receiving groove 311 turns into the arc groove 321, and fix the clamp 34 to the wing plate 32 by bolts to fix the lock column 31.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
