Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete parts, in particular to a splicing structure of a prefabricated concrete cable trench. Background Art

[0002] Cables are usually buried underground. When laying, trenches are dug on the ground in advance and then poured with cement or concrete. However, with the improvement of technology, prefabricated concrete cable trenches are used, that is, trenches are first dug on the ground and then prefabricated concrete cable trenches are placed in the splicing structure.

[0003] At present, the splicing structure of precast concrete cable trenches adopts modular splicing. The splicing between two precast concrete cable trenches will cause the splicing to be not rigorous and produce a large splicing seam.

[0004] To this end, we propose a splicing structure of precast concrete cable trench to solve the above problems. Utility Model Content

[0019] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 A splicing structure of a precast concrete cable trench, which includes a concave plate 1. A concave plate 1 is used between two adjacent sections of precast concrete cable trenches. Before laying the two sections of precast concrete cable trenches, the concave plate 1 is first placed in a pre-dug trench, and then the end of the precast concrete cable trench is placed in the concave plate 1. The concave plate 1 wraps the splicing seam of the two sections of precast concrete cable trenches. Aluminum sheets 2 are installed on both inner walls and the inner bottom of the concave plate 1. The aluminum sheets 2 on both sides of the concave plate 1 are pressed on the aluminum sheet 2 at the bottom, that is, after the precast concrete cable trench is placed in, it will form a close contact with the aluminum sheet 2, and the aluminum sheet 2 covers the splicing seam of the two sections of precast concrete cable trenches.

[0023] The concave-shaped plate 1 is prefabricated by using a steel mesh and pouring concrete.

[0024] Considering that the precast concrete cable trench is placed into the concave plate 1 from top to bottom, if the spacing between the aluminum sheets 2 on both sides just matches the width of the precast concrete cable trench, the aluminum sheets 2 will be worn when placed in. Therefore, the aluminum sheets 2 on both sides of the concave plate 1 are movably connected to the concave plate 1, and a number of threaded rods 4 are threaded through the threads on both sides of the concave plate 1. One end of the threaded rod 4 is connected to the corresponding aluminum sheet 2, that is, before the cable trench is placed, the spacing between the aluminum sheets 2 on both sides is greater than the width of the precast concrete cable trench. After the cable trench is placed, a cross-shaped screwdriver is inserted into the cross-shaped opening 6 on the cross section of the other end of the threaded rod 4 to rotate the threaded rod 4. By rotating the threaded rod 4, the threaded rod 4 is moved closer to the concave plate 1, thereby squeezing the aluminum sheet 2 and pressing the aluminum sheet 2 on the joint seam.

[0025] Since the cable trench is made of concrete, its outer wall surface is not very flat. Therefore, in order to ensure that the aluminum sheet 2 can fit tightly, steel bars 3 are installed around the opposite sides of the aluminum sheet 2 on both sides. The threaded rod 4 is connected to the steel bar 3 through a bearing 5. The steel bar 3 is used to ensure that every part around the aluminum sheet 2 can be subjected to the pressure brought by the threaded rod 4.

[0026] Among them, since the aluminum sheet 2 and the steel bar 3 can be deformed, when subjected to force, the aluminum sheet 2 can be more closely fitted to the outer wall of the cable trench.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
