Description

Technical Field

[0001] The utility model relates to the technical field of bridge frames, in particular to a glass fiber reinforced plastic trough type bridge frame. Background Art

[0002] Cable trays are divided into trough-type cable trays, tray-type cable trays, ladder-type cable trays, grid cable trays and other structures. They are composed of brackets, supports and installation accessories. They can be erected independently or laid on various buildings and pipe gallery brackets. They have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts need to be galvanized. For bridges installed in the open air outside buildings, if they are near the seaside or in corrosion areas, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion and high impact strength.

[0003] In the prior art, the impact resistance of FRP is weaker than that of metal bridges. When subjected to external force or collision, the bridge may be more likely to break or be damaged, affecting its structural integrity and cable protection function. Although FRP itself has good corrosion resistance, under extreme climatic conditions, such as long-term exposure to strong ultraviolet rays, it may accelerate the aging process, causing the bridge to fade in color and reduce its strength. Temperature changes may also affect the dimensional stability of the FRP bridge. Especially in an environment with drastic temperature changes, the bridge may expand or contract slightly, affecting the installation accuracy and the tight fixation of the cable. Therefore, the present application provides a FRP trough-type bridge to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a FRP trough type bridge to solve the problems that the existing FRP bridge has weak impact resistance, and temperature changes may affect the dimensional stability of the FRP bridge, causing slight expansion or contraction, affecting the installation accuracy and tight fixation of cables.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A fiberglass trough bridge includes a bridge body, which includes an inner layer and an outer layer. The inner layer is made of standard fiberglass, the matrix of which is a thermosetting resin, and the outer layer is a reinforced fiber grid structure; and reinforcing ribs are arranged between the inner layer and the outer layer.

[0007] The outer layer is coated with an anti-ultraviolet coating.

[0008] The connecting part is rotatably mounted on the bridge frame body, and the connecting part comprises a telescopic piece and a clamping piece mounted on the telescopic piece.

[0009] The connecting portion further includes: a limiting member installed on the clamping member.

[0010] The first slot is provided on the main body of the bridge frame and is used in conjunction with the telescopic member; the second slot is provided on the main body of the bridge frame and is used in conjunction with the clamping member.

[0011] Slot three is provided on slot one to facilitate the rotation of the clamp, and the depth of slot three is greater than the sum of the depths of the clamp and the limiting member; a positioning hole is provided on slot three to cooperate with the limiting member for limiting.

[0012] The reinforcing ribs are made of glass fiber reinforced plastic.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above scheme, by setting the inner layer, outer layer and reinforcing ribs, the reinforcing ribs can significantly improve the load-bearing capacity of the bridge, so that it can support heavier loads such as cables or pipes. The addition of reinforcing ribs between the inner and outer layers helps to reduce the bending and deformation of the bridge when subjected to external forces, thereby improving the rigidity of the entire structure. The reinforcing ribs can prevent fatigue cracks in the bridge under repeated loads or impacts, thereby extending the service life of the bridge. When the bridge is subjected to uneven loads, the reinforcing ribs help to distribute stress more evenly and avoid damage caused by stress concentration. Thermosetting resin, as the matrix of fiberglass, will not soften or deform due to temperature changes after curing, thereby helping to maintain the dimensional stability of the bridge.

DETAILED DESCRIPTION

[0026] The following describes in detail a fiberglass trough bridge provided by the present invention, in conjunction with the accompanying drawings and specific embodiments. It is also noted that, in order to provide a more detailed description, the following embodiments are best and preferred embodiments, and those skilled in the art may also adopt other alternatives for implementing certain known technologies. Furthermore, the accompanying drawings are only for the purpose of describing the embodiments in more detail and are not intended to limit the present invention in any specific manner.

[0027] like Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, an embodiment of the present invention provides a glass fiber reinforced plastic trough type bridge frame, including a bridge frame body 1, the bridge frame body 1 includes: an inner layer 103 and an outer layer 101, the inner layer 103 is made of standard glass fiber reinforced plastic material, the matrix of the glass fiber reinforced plastic is a thermosetting resin, and the outer layer 101 is a reinforced fiber grid structure; reinforcing ribs 102 are arranged between the inner layer 103 and the outer layer 101.

[0028] The reinforcement ribs 102 significantly improve the load-bearing capacity of the bridge, enabling it to support heavier loads such as cables or pipes, helping to reduce the bending and deformation of the bridge when subjected to external forces, and improving the rigidity of the entire structure. The reinforcement ribs 102 can prevent fatigue cracks in the bridge under repeated loads or impacts, thereby extending the service life of the bridge. When the bridge is subjected to uneven loads, the reinforcement ribs 102 help to distribute the stress more evenly and avoid damage caused by stress concentration.

[0029] like Figure 2 As shown, the outer layer 101 is coated with an anti-ultraviolet coating.

[0030] The surface of the bridge is treated with a special UV-resistant coating, such as a weather-resistant polyurethane or polyvinylidene fluoride (PVDF) coating, to further improve weather resistance.

[0031] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, the connecting part 2 is rotatably mounted on the bridge main body 1 , and the connecting part 2 includes: a telescopic member 201 ; and a clamping member 202 mounted on the telescopic member 201 .

[0032] The telescopic member 201 is used to drive the clamping member 202 to move so that the clamping member 202 enters the interior of the clamping slot, thereby enabling quick installation and removal and improving work efficiency.

[0033] like Figure 1 、 Figure 3 and Figure 4 As shown, the connecting portion 2 further includes: a limiting member 203 installed on the clamping member 202 .

[0034] The limiting member 203 is used to limit the rotation of the telescopic member 201 to prevent it from falling off after being limited, thereby improving the stability of the connecting part 2.

[0035] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the slot 1 3 is provided on the bridge body 1 for use with the telescopic member 201 ; the slot 2 4 is provided on the bridge body 1 for use with the clamping member 202 .

[0036] Slot 1-3 allows the telescopic member 201 to slide inside or outside the bridge body 1 to adjust the bridge length. Its functions include providing a movement path for the telescopic member 201, ensuring smooth movement to the desired position, limiting the movement direction of the telescopic member 201 to prevent it from shifting or twisting during adjustment, and reducing friction between the telescopic member 201 and the bridge body 1, making the adjustment process easier and smoother.

[0037] like Figure 3 、 Figure 5 and Figure 7 As shown, slot three 5 is provided on slot one 3 to facilitate the rotation of the clamping member 202. The depth of slot three 5 is greater than the sum of the depths of the clamping member 202 and the limiting member 203. The positioning hole 6 is provided on slot three 5 to cooperate with the limiting member 203 for limiting.

[0038] The function of the slot three 5 includes providing sufficient space for the clamp 202 to rotate, so that the clamp 202 can smoothly lock or unlock the telescopic part 201. Since the depth of the slot three 5 is greater than the sum of the depths of the clamp 202 and the limit member 203, it ensures that the clamp 202 will not be obstructed by the bridge frame body 1 when rotating.

[0039] like Figure 2 As shown, the material of the reinforcing rib 102 is glass fiber reinforced plastic.

[0040] Glass fiber reinforced plastic is a composite material that provides high strength and high modulus, which can significantly improve the structural strength of the cable tray body 1, especially when subjected to tensile, compressive and bending loads. Glass fiber reinforced plastic has good electrical insulation properties, which is an additional advantage for cable trays because it can reduce electromagnetic interference and improve safety.

[0041] The technical solution provided by the present invention is that when in use, two adjacent bridge frames 1 are connected through the connecting part 2, the telescopic member 201 is extended, driving the clamping member 202 to move, and moves through the slot 1 3 and the slot 2 4 to the slot 3 5, and the telescopic member 201 is rotated, and the limiting member 203 enters the positioning hole 6 through the telescopic member 201.

[0042] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
