Description

Technical Field

[0001] The utility model belongs to the technical field of galvanized sheets, and more specifically, particularly relates to a composite galvanized sheet. Background Art

[0002] Galvanized steel sheet is a process of coating the surface of steel sheet with a layer of zinc. The purpose of galvanizing is to prevent corrosion of the steel sheet and extend its service life. Galvanized steel sheet can provide many advantages, such as corrosion resistance, durability, strength, aesthetics and plasticity. Composite galvanized sheet, as the name suggests, is a sheet formed by galvanizing the composite sheet.

[0003] Although the existing composite galvanized sheet can achieve strength improvement by combining high-hardness materials, it cannot further improve the strength through structural improvements, such as setting snap-in protrusions, and cannot improve the connection strength of the composite sheet through the snap-in protrusions. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a composite galvanized sheet to solve the problem that the existing composite galvanized sheet, although it can achieve strength improvement by compounding high-hardness materials, cannot further improve the strength through structural improvements, such as setting a snap-in protrusion, and cannot improve the connection strength of the composite sheet through the snap-in protrusion.

[0005] The purpose and effect of the composite galvanized sheet of the utility model are achieved by the following specific technical means:

[0006] A composite galvanized plate comprises a steel plate body, which is a rectangular plate structure. The top and bottom end surfaces of the steel plate body are both extruded and connected with a load-bearing plate, the upper load-bearing plate is coated with a galvanized layer, and the bottom end surface of the lower load-bearing plate is also coated with a galvanized layer.

[0007] Among them, the load-bearing plate is a HARDOX series high-hardness steel plate, the hardness of the load-bearing plate is greater than the hardness of the steel plate body, the two load-bearing plates together constitute the reinforcement structure of the steel plate body, and the two load-bearing plates and the steel plate body together constitute a composite plate.

[0008] Among them, the two load-bearing plates are both welded with first clamping protrusions in a linear array shape, the first clamping protrusions are rectangular clamping block structures, and the first clamping protrusions welded in a linear array shape are reinforcement parts of the load-bearing plates.

[0009] Among them, the top end surface of the steel plate body is extruded in a linear array with a first card slot, and the bottom end surface of the steel plate body is also extruded in a linear array with a first card slot, and the first card slot is a rectangular slot structure; the first clamping protrusions on the two load-bearing plates are both clamped with the first card slot.

[0010] Among them, the first clamping protrusions on the upper load-bearing plate are distributed horizontally, and the first clamping protrusions on the lower load-bearing plate are distributed vertically.

[0011] Among them, the top end surface of the upper load-bearing plate is welded with a second clamping protrusion in a linear array, and the bottom end surface of the lower load-bearing plate is welded with a second clamping protrusion in a linear array. The second clamping protrusion is a rectangular block structure, and the second clamping protrusion welded in a linear array is a reinforcement part of the load-bearing plate.

[0012] Wherein, the bottom of each galvanized layer is provided with second clamping grooves in a linear array, and the second clamping grooves arranged in a linear array are clamped with the second clamping protrusions.

[0013] The steel plate body is provided with plug-in holes in a linear array, the plug-in holes are circular hole structures, a steel bar is plugged into each plug-in hole, and the steel bars plugged in the linear array are reinforcement parts of the steel plate body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The present application can strengthen the steel plate body by setting the load-bearing plate, thereby improving the overall strength and avoiding deformation of the steel plate body during use.

[0016] The present application adopts the provision of the first clamping protrusion. On the one hand, the first clamping protrusion can improve the inherent strength of the load-bearing plate and reduce the probability of the load-bearing plate being deformed by force; on the other hand, the clamping of the first clamping protrusion and the first clamping groove can improve the connection strength between the load-bearing plate and the steel plate body, thereby ultimately improving the overall strength of the composite plate.

[0017] The present application can, on the one hand, further improve the strength of the load-bearing plate by setting the second clamping protrusion; on the other hand, the connection strength of the galvanized layer on the load-bearing plate can be improved by clamping the second clamping groove and the second clamping protrusion.

[0030] The utility model provides a composite galvanized sheet, comprising a steel sheet body 1, the steel sheet body 1 is a rectangular plate structure, the top end surface and the bottom end surface of the steel sheet body 1 are both connected with a load-bearing plate 2 through extrusion, the upper load-bearing plate 2 is coated with a galvanized layer 3, and the bottom end surface of the lower load-bearing plate 2 is also coated with a galvanized layer 3.

[0031] Among them, the load-bearing plate 2 is a HARDOX series high-hardness steel plate, the hardness of the load-bearing plate 2 is greater than the hardness of the steel plate body 1, the two load-bearing plates 2 together constitute the reinforcement structure of the steel plate body 1, and the two load-bearing plates 2 and the steel plate body 1 together constitute a composite plate.

[0032] Among them, the two load-bearing plates 2 are both welded with first clamping protrusions 201 in a linear array. The first clamping protrusions 201 are rectangular block-like structures. The first clamping protrusions 201 welded in a linear array are reinforcement parts of the load-bearing plates 2. During use, the first clamping protrusions 201 can improve the strength of the load-bearing plates 2 themselves, and reduce the probability of the load-bearing plates 2 being deformed by force.

[0033] Among them, the top end surface of the steel plate body 1 is extruded with a first card groove 101 in a linear array, and the bottom end surface of the steel plate body 1 is also extruded with a first card groove 101 in a linear array, and the first card groove 101 is a rectangular groove structure; the first clamping protrusions 201 on the two load-bearing plates 2 are both clamped with the first card groove 101. During use, the connection strength between the load-bearing plate 2 and the steel plate body 1 can be improved by clamping the first clamping protrusion 201 with the first card groove 101, thereby improving the overall strength of the composite plate.
