DETAILED DESCRIPTION

[0019] Referring to Figures 1 to 5 The utility model discloses a fiber reinforced ultrathin concrete embedded board structure, including: embedded board body 1, embedded board body 1 outside face is provided with high density polyethylene plate frame 2,

[0020] The high-density polyethylene plate frame 2 is provided with a first steel plate layer 3 and a second steel plate layer 31 on the inner side, and a support rib plate 32 is welded between the first steel plate layer 3 and the second steel plate layer 31. A first carbon fiber resin composite plate layer 4 is bonded to the lower surface of the first steel plate layer 3, and a second carbon fiber resin composite plate layer 6 is bonded to the upper surface of the second steel plate layer 31. A polyethylene fiber composite plate layer 5 is bonded between the first carbon fiber resin composite plate layer 4 and the second carbon fiber resin composite plate layer 6.

[0021] The chimeric plate body 1 is composed of the high-density polyethylene plate frame 2, the first steel plate layer 3, the second steel plate layer 31, the support rib plate 32, the first carbon fiber resin composite plate layer 4, the polyethylene fiber composite plate layer 5, and the second carbon fiber resin composite plate layer 6. The polyethylene fiber composite plate layer 5, the first carbon fiber resin composite plate layer 4, and the second carbon fiber resin composite plate layer 6 form the reinforced fiber main structure of the chimeric plate body 1, which increases the compressive strength and bearing strength of the reinforced concrete chimeric plate as a whole, while reducing the overall weight of the concrete chimeric plate. The first steel plate layer 3, the second steel plate layer 31, and the support rib plate 32 form a H-shaped support structure, and the reinforced fiber main structure composed of the polyethylene fiber composite plate layer 5, the first carbon fiber resin composite plate layer 4, and the second carbon fiber resin composite plate layer 6 is filled into the H-shaped support structure. When the actual load is large, the area of the reinforced fiber main structure is increased, so that the reinforced fiber main structure fills the cavity, without changing the thickness of the chimeric plate body 1, while increasing the bearing strength of the chimeric plate body 1. This facilitates the adjustment of the area of the reinforced fiber main structure filled into the cavity of the H-shaped support structure to meet the actual load requirements, avoids the over-thickness of the concrete chimeric plate affecting the pouring effect of the concrete, and further improves the bearing capacity of the concrete chimeric plate in the horizontal and vertical directions.

[0022] In this embodiment, the first steel plate layer 3 and the second steel plate layer 31 are extruded and wrapped with the high-density polyethylene plate frame 2.

[0023] As a preferred embodiment, the high-density polyethylene plate frame 2 is extruded and wrapped on the outer surface of the first steel plate layer 3 and the second steel plate layer 31. The material of the high-density polyethylene plate frame 2 has a compact molecular chain arrangement and high crystallinity, which makes the high-density polyethylene plate frame 2 have excellent strength and rigidity, and can withstand a large pressure and weight.

[0024] In this embodiment, the coupling column 21 is provided with a convex point 22, and the coupling column 21 is arranged in a convex cylindrical shape on the outer surface of the high-density polyethylene plate frame 2.

[0025] As a preferred embodiment, the bonding column 21 of the outer end surface of the high-density polyethylene plate frame 2 is uniform in cross-sectional shape, the stress points are dispersed, and when subjected to pressure, it can uniformly bear pressure, so that the embedded plate body 1 is uniformly stressed, avoiding local excessive stress that can damage the embedded plate body 1, and the convex points 22 of the column surface of the bonding column 21 make the column surface not smooth, which can better combine with the poured concrete, ensuring that the embedded plate body 1 can be firmly and stably embedded in the concrete and is not easy to fall off.

[0026] In this embodiment, the support rib plate 32 is perpendicular to the first steel plate layer 3 and the second steel plate layer 31, and the support rib plate 32 is provided with a composite cavity 33 at the adjacent interval. The composite cavity 33 is filled with a polyethylene fiber composite plate layer 5.

[0027] As a preferred embodiment, the support rib plate 32, the first steel plate layer 3 and the second steel plate layer 31 form a H-shaped support structure of the embedded plate body 1, which has a large cross section and high bearing capacity, can effectively resist pressure, and further improves the bearing capacity of the embedded plate body 1 in the horizontal and vertical directions. The support rib plate 32, the first steel plate layer 3 and the second steel plate layer 31 are made of ultra-thin high-strength steel, so that the support rib plate 32, the first steel plate layer 3 and the second steel plate layer 31 can bear greater load while being more lightweight, avoiding the influence of the embedded plate body 1 on the combination effect with the concrete due to excessive weight. The composite cavity 33 is a filling cavity for the polyethylene fiber composite plate layer 5, the first carbon fiber resin composite plate layer 4 and the second carbon fiber resin composite plate layer 6, and the actual area of the polyethylene fiber composite plate layer 5, the first carbon fiber resin composite plate layer 4 and the second carbon fiber resin composite plate layer 6 filled in the cavity determines the bearing strength of the embedded plate body 1 as a whole. By increasing or decreasing the area of the reinforcing fiber main structure composed of the polyethylene fiber composite plate layer 5, the first carbon fiber resin composite plate layer 4 and the second carbon fiber resin composite plate layer 6 filled in the cavity of the H-shaped support structure, the actual bearing requirement is met, and the influence of the concrete embedded plate on the pouring effect of the concrete is avoided.

[0028] In this embodiment, the thickness of the polyethylene fiber composite plate layer 5 is 3-5mm, and the thickness of the first carbon fiber resin composite plate layer 4 and the second carbon fiber resin composite plate layer 6 is 0.5-2mm.

[0029] As a preferred embodiment, the first carbon fiber resin composite plate layer 4 and the second carbon fiber resin composite plate layer 6 are materials composed of carbon fibers and resin (such as epoxy resin, phenolic resin, etc.) as a matrix, so that the first carbon fiber resin composite plate layer 4 and the second carbon fiber resin composite plate layer 6 have the advantages of high specific strength, high specific modulus, fatigue resistance, corrosion resistance, etc. The polyethylene fiber composite plate layer 5 is a material composed of ultra-high molecular weight polyethylene fiber and polyurethane, which improves the wear resistance and impact resistance of the original material ultra-high molecular weight polyethylene fiber. The first carbon fiber resin composite plate layer 4, the second carbon fiber resin composite plate layer 6 and the polyethylene fiber composite plate layer 5 constitute the reinforced fiber main structure of the embedded plate body 1, which has high strength and high bearing capacity, and can effectively enhance the compressive strength and bearing strength of the embedded plate body 1 as a whole, while reducing the overall weight of the embedded plate body 1.

[0030] In the present embodiment, the thickness of the first steel plate layer 3 and the second steel plate layer 31 is 0.5-3mm.

[0031] As a preferred embodiment, the reinforced fiber main structure of light material, the ultra-thin first steel plate layer 3 and the second steel plate layer 31 can reduce the weight of the embedded plate body 1, make the embedded plate body 1 itself more lightweight, avoid the influence of the embedded plate body 1 on the pouring effect of concrete due to excessive thickness, facilitate the better combination of the ultra-thin embedded plate body 1 with the poured concrete, and be applicable to thin building structures, so as to reduce the thickness of the building structure while ensuring the corresponding bearing capacity.

[0032] The fiber-reinforced ultra-thin concrete embedded plate structure of the utility model can effectively solve the problem that the existing embedded plate usually increases its thickness to meet the bearing requirement, and the thick embedded plate easily reduces the concrete pouring effect, enhances the compressive strength and bearing strength of the concrete embedded plate as a whole, reduces the overall weight of the concrete embedded plate, meets the actual bearing requirement by increasing or decreasing the area of the reinforced fiber main structure filled in the cavity of the inverted U-shaped support structure, avoids the influence of the thick concrete embedded plate on the pouring effect of concrete, further improves the bearing capacity of the concrete embedded plate in the horizontal and vertical directions, and is applicable to the fiber-reinforced ultra-thin concrete embedded plate structure.
