Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cement composite steel plates, specifically a cement composite steel plate with a fiber-reinforced structure. Background Technology
[0002] Cement-coated steel plates are a composite structure that combines metal and cement-based materials. They are widely used in building protection, industrial explosion-proof and other fields, and have the characteristics of high strength, lightweight and convenient construction.
[0003] For example, the Chinese authorized patent CN217480468U (A Fiber Cement Composite Steel Plate) includes steel plates on both sides and a cement layer in the middle, as well as a fiber mesh and a threaded sleeve. The fiber mesh is made of glass fiber and is stacked on the inner layer of the steel plate. The steel plate has multiple regularly arranged perforations, and the threaded sleeve is disposed in the perforations at the edge of the steel plate. The threaded sleeve is coaxially arranged with the perforations and its two ends contact the inner sidewalls of the two steel plates. This utility model of fiber cement composite steel plate, through the embedded threaded sleeve, facilitates the threaded installation of explosion-proof plates, saving time and effort, and the composite fiber mesh increases impact resistance.
[0004] However, existing cement-reinforced steel plates rely on a single cement inner layer, resulting in poor strength and a tendency for cement to detach from the steel plate. Furthermore, when splicing multiple cement-reinforced steel plates, misalignment at the joints and large gaps can lead to inconvenient and unstable splicing. Therefore, they do not meet the current requirements. To address this, we propose a cement-reinforced steel plate with a fiber-reinforced structure. Utility Model Content
[0005] The purpose of this utility model is to provide a cement composite steel plate with a fiber-reinforced structure to solve the problems mentioned in the background art, such as the existing cement composite steel plate relying on a single cement inner layer, having poor strength, being prone to cement and steel plate detachment, and the joints being prone to misalignment and large gaps when splicing multiple cement composite steel plates, resulting in inconvenient and unstable splicing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement composite steel plate with a fiber-reinforced structure, comprising: a first galvanized steel plate, a fiber-reinforced cement plate disposed at the lower end of the first galvanized steel plate, a second galvanized steel plate disposed at the lower end of the fiber-reinforced cement plate, wherein the first galvanized steel plate and the second galvanized steel plate sandwich the fiber-reinforced cement plate, reinforcing components are disposed on both sides of the first galvanized steel plate, the second galvanized steel plate and the fiber-reinforced cement plate, a pressing edge is disposed on one side of the first galvanized steel plate and the fiber-reinforced cement plate, and a connecting edge is disposed on one side of the second galvanized steel plate.
[0007] Preferably, the fiber-reinforced cement board is provided with stabilizing protrusions on both the upper and lower surfaces, and multiple stabilizing protrusions are provided.
[0008] Preferably, the lower surface of the first galvanized steel plate and the upper surface of the second galvanized steel plate are provided with stabilizing slots, and the stabilizing protrusions are inserted into the stabilizing slots.
[0009] Preferably, both sides of the first galvanized steel plate and the second galvanized steel plate are provided with a first inner groove, the inner wall of the first inner groove is provided with a reinforcing slot, both sides of the fiber-reinforced cement board are provided with a second inner groove, and multiple first inner grooves and multiple second inner grooves are provided.
[0010] Preferably, the reinforcing assembly includes a reinforcing plate and a reinforcing insert, with the reinforcing insert located at both ends on one side of the reinforcing plate and inserted into the reinforcing slot.
[0011] Preferably, the upper surface of the connecting edge is provided with a limiting insert, the lower surface of the pressing edge is provided with a limiting slot, and the limiting insert is inserted into the limiting slot.
[0012] Preferably, the thickness of the first galvanized steel sheet and the second galvanized steel sheet is 0.5 mm, and the thickness of the fiber-reinforced cement board is 8.5 mm.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model uses a first galvanized steel plate and a second galvanized steel plate to sandwich the fiber-reinforced cement board. The stabilizing protrusions on the upper and lower surfaces of the fiber-reinforced cement board are inserted into the stabilizing slots of the first galvanized steel plate and the second galvanized steel plate, respectively, which improves the connection stability, makes it less prone to displacement, and also increases the connection area, making it less prone to separation and falling off. When two cement composite steel plates are spliced and placed, the lower pressing edge of one cement composite steel plate rests on the connecting edge of the other cement composite steel plate, and the limiting strip is inserted into the limiting slot, which achieves connection stability and positioning effect, makes it less prone to splicing displacement, improves installation convenience and efficiency, and solves the problem that existing cement composite steel plates rely on a single cement inner layer, have poor strength, and are prone to cement and steel plate falling off. In addition, when multiple cement composite steel plates are spliced, the connection is prone to misalignment and large gaps, resulting in inconvenient and unstable splicing.
[0015] (2) By setting reinforcing components on both sides of the fiber-reinforced cement board, when installing the reinforcing components, the reinforcing insert is inserted into the reinforcing slot. The reinforcing plate is located inside the space formed by the first inner groove and the second inner groove, which plays a connecting and reinforcing role for the first galvanized steel plate and the second galvanized steel plate, thereby further improving the stability of the first galvanized steel plate, the second galvanized steel plate and the fiber-reinforced cement board, and making them less likely to separate and fall off.

The thickness of both the first galvanized steel plate 1 and the second galvanized steel plate 2 is 0.5 mm, and the thickness of the fiber-reinforced cement plate 3 is 8.5 mm. The first galvanized steel plate 1 and the second galvanized steel plate 2 provide a sandwiching effect on the fiber-reinforced cement plate 3. Figure 1As shown, after the first galvanized steel plate 1 and the second galvanized steel plate 2 are punched, the fiber-reinforced cement board 3 is pressed together by a press using the first galvanized steel plate 1 and the second galvanized steel plate 2.

It also forms the pressing edge 4 and the connecting edge 5.
[0023] When two cement composite steel plates are spliced and placed, the lower pressing edge 4 of one cement composite steel plate rests on the connecting edge 5 of the other cement composite steel plate, and the limiting strip 6 is inserted into the limiting slot 7, which plays a role in connection stability and positioning, making it less likely to be spliced off-center, and improving installation convenience and efficiency.
