Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass curved cover plates, and in particular to a fiberglass curved cover plate with a pre-embedded reinforced structure. Background Technology

[0002] For the large-span fiberglass arc-shaped covers used for sealing sewage tanks in the current waste gas treatment industry, the strength of the covers is mainly improved by utilizing the cross-sectional dimensions of the covers and setting reinforcing ribs in the shape, or by adding metal pipes bent into arc shapes on the back of the covers.

[0003] The main drawbacks of the above two methods are: 1. The increase in strength by utilizing cross-sectional shape or setting reinforcing ribs in the structure is limited, and complex reinforcing rib structures will increase the cross-sectional size, leading to a significant increase in the difficulty of production and raw material costs; 2. The product structure formed by fiberglass on the mold will increase the product's self-weight due to the density of fiberglass itself, which will not only increase its own arch height and settlement, but also make it difficult to handle, install and disassemble; In view of the above drawbacks, this application is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fiberglass arc-shaped cover plate with a pre-embedded reinforced structure. By pre-embedding lightweight foam material as a reinforcing rib on the back of the cover plate, the rigidity of the arc-shaped cover plate is improved while reducing the self-weight of the cover plate, thereby reducing the overall cost and solving the problems of high cost and heavy weight caused by the current method of setting reinforcing ribs for fiberglass arc-shaped cover plates.

[0005] To address the aforementioned problems, this utility model provides a pre-embedded reinforced fiberglass arc-shaped cover plate, comprising an arc-shaped fiberglass main body layer, a reinforcing layer, and a covering layer arranged sequentially. The reinforcing layer includes a frame and beams, both made of lightweight foam material. The beams are arranged within the area enclosed by the frame and include several connecting beams. Slots are provided at the intersections of the connecting beams to allow for the interlocking of two sets of connecting beams. The covering layer includes a chopped strand mat layer, a fiberglass cloth layer, and a fiberglass covering layer arranged sequentially from the inside out. After the fiberglass covering layer cures, a raised reinforcing structure is formed on the surface of the fiberglass arc-shaped cover plate. The frame and beams form stiffening beams, providing reliable support for the cover plate's main structure. Ultimately, this improves the overall rigidity and deformation resistance of the cover plate, thereby minimizing product thickness, weight, manufacturing difficulty, and production costs.

[0006] According to one embodiment of the present invention, the reinforcing layer further includes an end positioning member, and the frame body contacts the end positioning member to position the arrangement of the frame body.

[0007] According to an embodiment of the present utility model, two sets of end positioning members are provided, which are respectively arranged on both sides of the frame body, and the end positioning members are arranged at the root positions of the flanges at both ends of the cover plate, further ensuring the accuracy of the arrangement position of the frame body. At the same time, the end positioning members can also effectively transfer the horizontal thrust received by the reinforcing ribs to the flange, thereby avoiding damage to the foam material caused by the deformation of the cover plate and reducing the performance of the cover plate.

[0008] According to an embodiment of the present utility model, the end positioning member has a U-shaped positioning surface, and the frame body contacts the U-shaped positioning surface, increasing the contact area.

[0009] According to an embodiment of the present utility model, the end positioning member is made of metal material, preferably welded by angle steel, and the welding can be in the form of H-shaped or U-shaped.

[0010] According to an embodiment of the present utility model, a plurality of grooves are provided on the frame body, and the grooves are provided to make the frame body form an arc structure.

[0011] According to an embodiment of the present utility model, the thickness of the lightweight foam material used for the frame body and / or the beam body is 50-100 mm, preferably 50 mm.

[0012] According to an embodiment of the present utility model, the lightweight foam material is polyurethane, PMI (polymethacrylimide) or XPS (extruded polystyrene foam).

[0013] According to an embodiment of the present utility model, the beam body adopts one or more of the arrangement modes of X-shaped, V-shaped, W-shaped, field-shaped, and Japanese-shaped.

[0014] The beneficial effect of the present utility model is that by pre-embedding a lightweight foam material and covering it with fiberglass on its surface, the rigidity and strength of the cover plate itself can be greatly improved, and it is better applicable to scenarios with large spans or high requirements for cover plate deformation. The pre-embedded lightweight foam material not only does not increase the weight of the product too much, but at the same time, the rigid skeleton structure formed by it can better maintain the stability of the cover plate, reduce the panel thickness and weight of the arc cover plate, thereby reducing production costs and improving installation efficiency.

The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

Example 1

[0022] A fiberglass arc-shaped cover plate with a pre-embedded reinforced structure, such as Figure 1 It includes an arc-shaped fiberglass main body layer 1, a reinforcing layer 2, and a covering layer 3 arranged sequentially.

[0023] like Figure 2 , Figure 3 The reinforcing layer 2 includes a frame body 22, a beam body 21, and an end positioning component 23. Both the frame body 22 and the beam body 21 are made of lightweight foam material, which can be selected from polyurethane, PMI (polymethacrylimide), or XPS (extruded polystyrene foam).

[0024] The frame 22 and / or beam 21 are made of lightweight foam material with a thickness of 50 mm.

[0025] The frame body 22 contacts the end positioning member 23 to position the frame body 22. Two sets of end positioning members 23 are provided, respectively located on both sides of the frame body 22. Preferably, the end positioning members 23 are located at the root of the flanges at both ends of the cover plate. The end positioning member 23 has a U-shaped positioning surface. The frame body 22 contacts the U-shaped positioning surface to increase the contact area. The end positioning member 23 is made of metal, preferably welded from angle steel. The welding can be H-shaped or U-shaped.

[0026] The end positioning component 23 is used to ensure the accuracy of the arrangement position of the frame body 22. At the same time, the end positioning component 23 can also effectively transfer the horizontal thrust of the reinforcing rib to the flange, thereby avoiding damage to the foam material and reducing the performance of the cover plate due to the deformation of the cover plate.

[0027] The frame 22 is preferably a square structure, composed of several standard length foam parts. Several grooves 221 are provided on the frame 22. The grooves 221 are used to make the frame 22 form an arc-shaped structure. The groove width of the grooves 221 is 3~5mm, the depth is 45mm, and the spacing is 100~250mm.

[0028] The beam body 21 is arranged within the area enclosed by the frame body 22. The beam body 21 includes a number of connecting beams 211. At the intersection positions of the connecting beams 211, clamping grooves 212 are provided for clamping two intersecting groups of connecting beams 211.

[0029] Such as Figure 4 , the beam body 21 can adopt one or more of the layout modes of X-shaped, V-shaped, W-shaped, field-shaped, and sun-shaped.

[0030] The coating layer 3 includes a chopped strand mat layer and a fiberglass cloth layer arranged in sequence from the inside to the outside, and finally is cured with a fiberglass reinforced plastic coating layer.

[0031] After the fiberglass reinforced plastic coating layer is cured, a raised stiffening structure is formed on the surface of the fiberglass arc-shaped cover plate. The frame body 22 and the beam body 21 form a stiffening beam, providing reliable support for the structure of the cover plate body, ultimately improving the rigidity and anti-deformation ability of the cover plate as a whole, so as to reduce the product thickness, weight, manufacturing difficulty and production cost to the greatest extent.

[0032] Manufacturing steps:

[0033] In this embodiment, polyurethane foam is preferably used. The cutting width can be selected from 50 to 100 mm according to the span of the cover plate, and the foam thickness specification can generally be selected as 50 mm;

[0034] Manufacture an arc-shaped cover plate on a fiberglass reinforced plastic mold. After it is pasted to the last layer of glass fiber and its surface is cured, a fiberglass reinforced plastic main body layer 1 is formed. Weld the H-shaped end positioning member 23 made of 5# angle steel to the root positions of the two ends of the flange of the fiberglass reinforced plastic main body layer 1 with fiberglass reinforced plastic fibers. After it is fixed, lay the grooved polyurethane foam material along the arc direction on the inner side of the fiberglass reinforced plastic main body layer 1 to form the frame body 22, and then paste and fix the fiberglass reinforced plastic at intervals of about 1.5 meters for positioning;

[0035] Lay the internal connecting beam polyurethane foam materials in sequence from one side to the other side of the fiberglass reinforced plastic main body layer 1. At the intersection positions, they need to be positioned and fixed firmly through the clamping grooves provided correspondingly on the foam materials. The two adjacent connecting beams need to be connected tightly to form the beam body 21;

[0036] On the surfaces of all the positioned polyurethane foams, cover a fiberglass material of "one mat and one cloth" (300 g / m 2 chopped strand mat + 400 g / m 2 fiberglass cloth) to form a rigid stiffening structure, and use fiberglass reinforced plastic to cover it. After the fiberglass reinforced plastic coating layer is cured and formed, a stiffening structure is formed on its outer surface.

[0037] This solution uses lightweight foamed materials with low density, minimizing the impact on the weight of the finished product. The framework shape is constructed using lightweight foamed materials, and a fiberglass structural layer is wrapped around its surface to form a rigid framework structure, significantly improving the strength, rigidity, bending and torsional resistance of the cover plate. The manufacturing process is also simple. Through the action of the lightweight foamed materials and the fiberglass structural layer they wrap, the thickness and weight of the curved cover plate can be reduced, thus lowering production costs.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
