Description

Technical Field

[0001] The utility model belongs to the field of cable trench building structures, and particularly relates to a cable trench cover plate and a processing mould thereof. Background Art

[0002] Cable trenches are channels for laying cables, and they require covers to protect the cables and facilitate maintenance. Conventional cable trench covers are rectangular concrete bypass members with limited structural strength. However, cable trenches are typically located at the edge of roads. With the increasing number of cars in modern society, some cars often press against the cable trench covers when parked on the roadside. Under the pressure of vehicles, the covers are prone to bending, damage, and collapse.

[0003] Some cover plates have embedded steel skeletons to increase strength, but when the cover plates are processed and cast, the internal steel bars are difficult to accurately position, which affects the quality consistency of the cover plate products.

[0004] Therefore, how to provide a cable trench cover with higher product strength, better quality consistency, and easier to withstand vehicle rolling becomes a problem that needs to be considered and solved by technical personnel in this field. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a cable trench cover plate and its processing mold with high quality and strength, good pressure-bearing performance, better and simpler processing technology.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A cable trench cover comprises a cover body which is in the shape of a rectangular plate as a whole, and steel bars are arranged inside the cover body. The invention is characterized in that a circle of angle steel is arranged around the periphery of the cover body, and the outer side surface of the angle steel constitutes the outer side surface of the cover plate. The two ends of the steel bars are welded and fixed to the angle steel and cast and fixed to the cover body as a whole.

[0008] In this way, a circle of angle steel is set around the cover plate to enclose the cover plate, greatly improving the edge strength and overall strength of the cover plate, increasing the cover plate's bearing capacity and effectively preventing the cover plate's edge from collapsing. At the same time, during processing, the angle steel at the edge of the cover plate forms part of the mold, allowing concrete to be poured directly into the angle steel, eliminating the need for separate side molds. In addition, the steel bars are directly welded to the angle steel for positioning, preventing shifting during pouring and vibration. This improves processing manufacturability and increases product quality stability and consistency.

[0009] Furthermore, the angle steel is L-shaped, with the outer side of the long side of the angle steel forming the outer side of the cover plate, and the short side of the angle steel located on the lower surface of the cover plate. This ensures better consistency of the product's upper surface appearance. In practice, the angle steel can also be made of homemade sheet metal. While the overall end face is L-shaped, the two end edges (a certain distance apart) are bent inward to form hooks. This achieves better strength at a lower cost.

[0010] Furthermore, the cover plate body is made of UHPC material, and a downwardly protruding cross-shaped reinforcement rib is provided in the middle of the lower surface of the cover plate body. The steel bar is cross-shaped and embedded in the reinforcement rib.

[0011] UHPC (Ultra-High Performance Concrete) is a high-strength casting material. Cover panels cast with this material, combined with a reinforcing rib structure embedded with steel bars, achieve higher strength with a thinner thickness and lighter weight. This significantly improves the cover's load-bearing capacity and compressive resistance while maintaining a lightweight design. Furthermore, because the steel bars are embedded within the ribs, the structural strength of the ribs is further enhanced, making them less susceptible to damage from collisions.

[0012] Furthermore, anti-slip strips protruding upwards and in the shape of long strips are arranged in parallel and at intervals on the upper surface of the cover body.

[0013] In this way, it can better prevent slipping and make it more convenient for pedestrians to walk.

[0014] Furthermore, a through hole is provided through at least one end of the cover body along the thickness direction.

[0015] In this way, it is convenient to open the cover by hooking it through the through hole when repairing the cable trench.

[0016] Furthermore, the angle steel is a hot-dip galvanized L-shaped grooved steel, which can better ensure strength and quality.

[0017] Furthermore, the steel bars used are No. 8 steel bars.

[0018] The utility model also discloses a cable trench cover plate processing mold, which is characterized in that it includes a bottom mold for forming the upper surface of the cover plate, the bottom mold is generally flat and the upper surface is provided with a groove consistent with the anti-slip strip on the cover plate body; it also includes a top mold for forming the lower surface of the cover plate, the top mold includes a template fixing frame located above, and also includes four back templates fixed on the lower surface of the template fixing frame and arranged in a field shape, and the four back templates are also provided with downwardly protruding angle steel blocks around them.

[0019] During processing, the pre-welded rectangular frame angle steel is placed directly on the top surface of the bottom formwork. The rebar is pre-welded and secured within the angle steel, forming a part of the mold. Concrete is then poured directly within the angle steel, and the top formwork is then pressed in place. The angle steel clamps secure and position the angle steel, while the four back formworks press down, forming the reinforcing rib structure on the underside of the cover plate between them. This makes the process simple and convenient, resulting in improved processability and greater product consistency.

[0020] Furthermore, a locking mechanism is provided between the bottom mold and the top mold, which facilitates mold locking during pouring, prevents displacement, and better ensures quality.

[0021] Furthermore, the locking mechanism is a tie bolt vertically penetrating the periphery of the bottom mold and the top mold, which has a simple structure and reliable clamping.

[0022] Furthermore, a vibration platform is provided below the bottom mold, and a clearance groove is provided on the upper surface of the vibration platform corresponding to the position of the tie bolts of the bottom mold, so as to facilitate the vibration after pouring and ensure the quality of the product.

[0023] In summary, the utility model has the advantages of high product quality and strength, good pressure bearing performance, and better and simpler processing technology. BRIEF DESCRIPTION OF THE DRAWINGS

The feature is that a circle of angle steel 3 is arranged around the cover body 1, and the outer side surface of the angle steel 3 constitutes the outer side surface of the cover. The two ends of the steel bars 2 are welded and fixed to the angle steel and cast and fixed to the cover body.

[0032] In this way, a circle of angle steel is set around the cover plate to enclose the cover plate, greatly improving the edge strength and overall strength of the cover plate, increasing the cover plate's bearing capacity and effectively preventing the cover plate's edge from collapsing. At the same time, during processing, the angle steel at the edge of the cover plate forms part of the mold, allowing concrete to be poured directly into the angle steel, eliminating the need for separate side molds. In addition, the steel bars are directly welded to the angle steel for positioning, preventing shifting during pouring and vibration. This improves processing manufacturability and increases product quality stability and consistency.

[0033] The angle steel 3 is L-shaped, with the outer side of the long side of the angle steel 3 forming the outer side of the cover plate, and the short side of the angle steel located on the lower surface of the cover plate. This ensures better consistency in the product's upper surface appearance. In another embodiment, the angle steel can also be made of homemade sheet metal. Based on the overall L-shaped end face, the two end edges (a certain distance apart) are bent inward to form a hook shape. This can achieve better strength at a lower cost.

[0034] In this embodiment, the cover plate body 1 is made of UHPC material. A downwardly protruding cross-shaped reinforcement rib 4 is provided in the middle of the lower surface of the cover plate body 1 . The steel bars 2 are cross-shaped and embedded in the reinforcement rib 4 .

[0035] UHPC (Ultra-High Performance Concrete) is a high-strength casting material. Cover panels cast with this material, combined with a reinforcing rib structure embedded with steel bars, achieve higher strength with a thinner thickness and lighter weight. This significantly improves the cover's load-bearing capacity and compressive resistance while maintaining a lightweight design. Furthermore, because the steel bars are embedded within the ribs, the structural strength of the ribs is further enhanced, making them less susceptible to damage from collisions.

[0036] The upper surface of the cover body 1 is provided with anti-slip strips 5 that are upwardly protruding and in the shape of long strips, arranged in parallel and at intervals.

[0037] In this way, it can better prevent slipping and make it more convenient for pedestrians to walk.

[0043] During processing, the pre-welded rectangular frame angle steel is placed directly on the top surface of the bottom formwork. The rebar is pre-welded and secured within the angle steel, forming a part of the mold. Concrete is then poured directly within the angle steel, and the top formwork is then pressed in place. The angle steel clamps secure and position the angle steel, while the four back formworks press down, forming the reinforcing rib structure on the underside of the cover plate between them. This makes the process simple and convenient, resulting in improved processability and greater product consistency.

[0044] A locking mechanism is also provided between the bottom mold and the top mold, which facilitates mold locking during pouring, prevents displacement, and better ensures quality.

[0045] The locking mechanism is a tie bolt 11 vertically penetrating the periphery of the bottom mold and the top mold. This has a simple structure and reliable compression.
