Description

Technical Field

[0001] This invention relates to the field of electrical engineering construction technology, and in particular to a pre-embedded cable trough structure and its construction method for electromechanical engineering construction. Background Technology

[0002] Cable trough pre-embedding is a necessary step before laying cables in electrical / electromechanical engineering. Currently, cable troughs are mostly independent structures, which are made of metal and can be spliced ​​and assembled into square trough structures. Typically, the channel formed by the metal trough is used as the wiring channel. After positioning and measurement, the cables / wires are arranged in the wiring channel. Finally, the metal trough is sealed and the surface material is poured, thus completing the cable trough pre-embedding and wiring work.

[0003] For example, Chinese invention patent CN113708318B discloses a multi-channel wiring structure. However, its structure is too complex, and its design aims to avoid cable slippage and ensure stability after pre-embedding. Although the disclosed technology achieves the requirement of improving stability through the form of pre-embedded frame, its structure and weight exceed the requirements of various construction environments. It is only suitable for underground pre-embedded structures. No matter how its structure and size are changed, it cannot simultaneously meet the universal requirements of underground and wall surfaces. Therefore, it has strong limitations and high construction costs.

[0004] For example, the Chinese utility model patent with authorization announcement number CN208369168U discloses a pressure-resistant component. This structure uses springs as buffer structures in many places, and the cable channel wall is thickened. Although this can increase the structural strength, it still has the problems of high construction cost and limited use.

[0005] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a pre-embedded structure for cable troughs in electromechanical engineering construction and its construction method. Summary of the Invention

[0006] The purpose of this invention is to provide a pre-embedded cable trough structure and its construction method for electromechanical engineering construction. This pre-embedded cable trough structure is suitable for the synchronous arrangement of multiple parallel cables. It utilizes the pre-embedded shell to improve structural strength and prevent deformation of the internal cable trough. At the same time, the integrated and split pre-embedded structures can meet different wiring requirements, have more application scenarios, and meet the wiring requirements of different construction locations. The overall structure is relatively novel, mainly using conventional metal materials, which is not difficult to manufacture, and is convenient and flexible to construct, thereby reducing construction costs and simplifying the construction process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a pre-embedded cable trough structure for electromechanical engineering construction, the structure comprising: An embedded structural housing that matches the excavated wiring trench; and At least two cable trough assemblies are disposed inside the pre-embedded structure housing and extend along the extension direction of the pre-embedded structure housing. The pre-embedded structure shell is integrally embedded in the excavated wiring trench, and the pre-embedded structure shell includes a pre-embedded structure lower shell and a pre-embedded structure upper shell that are assembled and fixed. The cable trough assembly includes a lower cable trough housing and an upper cable trough housing that are assembled and fixed. The cable trough assembly forms an internal wiring channel for arranging cables through the lower and upper housings of the trough. The lower housing of the cable trough and the lower housing of the pre-embedded structure are an integral structure; The upper housing of the cable trough and the upper housing of the pre-embedded structure are an integral structure; When the upper shell of the pre-embedded structure is assembled and fixed to the lower shell of the pre-embedded structure, the upper shell of the cable trough is pressed and assembled and fixed to the lower shell of the cable trough by the upper shell of the pre-embedded structure.

[0008] Furthermore, the embedded structure is divided into a straight section and a transition section; The width of the pre-embedded structure matches the width of the excavated wiring trench, and the length of each straight section of the pre-embedded structure is 1000mm~2000mm.

[0009] Furthermore, in the straight section of the pre-embedded structure, two lower shells of the pre-embedded structure are arranged side by side inside the lower shell of the pre-embedded structure. The lower shells of the wire grooves are arranged close to the inner wall of the corresponding side of the lower shell of the pre-embedded structure, and a space for the installation of the pre-embedded structure is reserved between the lower shell of the wire grooves and the corresponding inner wall. The upper shell of the pre-embedded structure, arranged in a straight section, has a wire groove upper shell arranged side by side inside the upper shell of the pre-embedded structure to cooperate with the lower shell of the corresponding wire groove. The side wall of the wire groove upper shell and the side wall of the upper shell of the pre-embedded structure are an integral structure, and the wall thickness of the upper shell of the pre-embedded structure at the position where it cooperates with the upper shell of the wire groove is greater than the wall thickness at other positions.

[0010] Furthermore, the transition section of the pre-embedded structure is configured as a T-shaped structure, which is divided into a first transition section and a second transition section, with the first transition section and the second transition section arranged perpendicularly. The first transition section has two lower housings of the embedded structure arranged side by side inside the lower housing of the embedded structure. The lower housings of the wire grooves are arranged close to the inner wall of the corresponding side of the lower housing of the embedded structure, and the installation space of the embedded structure is reserved between the lower housing of the wire grooves and the corresponding inner wall. The second transition section has two wire groove lower housings arranged side by side inside the pre-embedded structure lower housing. The wire groove lower housings are arranged close to the inner wall of the corresponding side of the pre-embedded structure lower housing, and the installation space of the pre-embedded structure is reserved between the wire groove lower housing and the corresponding inner wall. The area where the extension lines of the lower housing of the pre-embedded structure of the first transition section and the lower housing of the pre-embedded structure of the second transition section overlap is a blank area. This blank area is used to adjust the direction of the cable when wiring in different directions. The upper shell of the pre-embedded structure of the first transition section has two upper shells of the wire groove arranged side by side inside the upper shell of the pre-embedded structure; the upper shell of the second transition section has two upper shells of the wire groove arranged side by side inside the upper shell of the pre-embedded structure. The upper housing of the wire groove mates with the corresponding lower housing of the wire groove; The side wall of the upper housing of the cable trough and the side wall of the upper housing of the pre-embedded structure are integral structures, and the wall thickness of the upper housing of the pre-embedded structure at the mating position with the upper housing of the cable trough is greater than the wall thickness at other positions.

[0011] Furthermore, expansion bolts or anchors are provided in the installation space of the pre-embedded structure lower shell, and the pre-embedded structure lower shell is assembled and fixed to the ground or wall by expansion bolts or anchors.

[0012] Furthermore, the upper housing of the wire trough includes an upper housing extension and an upper housing mounting portion; The upper housing extension and the upper housing mounting portion of the wire trough are formed into a stepped surface that mates with the lower housing of the wire trough. When the upper housing of the cable trough is installed on the upper end of the lower housing of the cable trough through the pre-embedded structure upper housing, the extension of the upper housing of the cable trough extends into the installation space of the pre-embedded structure, and the installation part of the upper housing of the cable trough overlaps with the end of the lower housing of the cable trough. The lower housing of the wire trough and the upper housing of the wire trough are fitted with a wedge-shaped groove at one end, and a sealing gasket is provided at the stepped surface. The sealing gasket is partially embedded in the wedge-shaped groove and partially extends into the pre-embedded structure installation space. The upper housing of the cable trough is fixed to the upper end of the lower housing of the cable trough by means of the snap-fit ​​between the sealing gasket and the wedge groove, and the interference fit between the sealing gasket and the extension of the upper housing of the cable trough and the pre-embedded structure installation space.

[0013] Furthermore, a docking structure is provided between adjacent pre-embedded structures to enable the docking of adjacent pre-embedded structures; The docking structure includes: A protrusion is formed at one end of the shell of the pre-embedded structure along the length direction, and a groove is formed at the other end of the shell of the pre-embedded structure along the length direction. Adjacent pre-embedded structures are connected by inserting the protrusion into the adjacent groove for positioning.

[0014] Furthermore, U-shaped clips are provided in the blank area to secure cables within that area.

[0015] This invention also discloses a construction method for a pre-embedded structure of cable troughs in electromechanical engineering construction. This construction method is based on the pre-embedded structure described above, and mainly includes the following steps: S100. Laying out and positioning: Determining the wiring location and direction of electrical equipment; S200. Based on the layout and positioning results, determine the number of straight sections and the number of transition sections, and at the same time determine the layout position of the transition sections.

[0016] Furthermore, in step S500, when arranging cables in the lower housing of the transfer section's cable tray, U-shaped clips are used to reinforce and fix the cables in the blank areas. Furthermore, the end of the transition section that is not connected to the straight section is sealed by a steel plate.

[0017] The above technical solution provides a pre-embedded cable trough structure and its construction method for electromechanical engineering construction, which has the following beneficial effects: The cable trough pre-embedded structure of this invention is suitable for the synchronous arrangement of multiple parallel cables. The pre-embedded shell improves the structural strength and prevents deformation of the internal cable trough. At the same time, the integrated pre-embedded structure and the split pre-embedded structure can meet the use of different wiring requirements, with more application scenarios and meeting the wiring requirements of different construction locations. The overall structure is relatively novel, and the materials are mainly conventional metal materials.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] See Figures 1 to 9 As shown; This embodiment discloses a pre-embedded cable trough structure for electromechanical engineering construction. The structure includes: An embedded structural housing that matches the excavated wiring trench 11; and At least two cable tray assemblies are disposed inside the pre-embedded structure housing and extend along the extension direction of the pre-embedded structure housing. The pre-embedded structure shell is embedded in the excavated wiring groove 11, and the pre-embedded structure shell includes the pre-embedded structure lower shell 101 and the pre-embedded structure upper shell 102 that are assembled and fixed. The cable trough assembly includes a lower housing 201 and an upper housing 202 of the cable trough that are assembled and fixed. The cable tray assembly forms an internal wiring channel 203 for arranging cables 4 through the lower housing 201 and the upper housing 202 of the cable tray; The lower housing 201 of the cable tray and the lower housing 101 of the pre-embedded structure are an integral structure; The upper housing 202 of the cable tray and the upper housing 102 of the pre-embedded structure are an integral structure; When the upper housing 102 of the pre-embedded structure is assembled and fixed to the lower housing 101 of the pre-embedded structure, the upper housing 202 of the wire trough is pressed and assembled and fixed to the lower housing 201 of the wire trough by the upper housing 102 of the pre-embedded structure.

[0023] Specifically, this embodiment discloses a novel cable trough pre-embedded structure suitable for electromechanical engineering construction. It abandons the method of simply using the cable trough as a pressure-bearing component, instead setting a pre-embedded structure shell outside the cable trough. The pre-embedded structure of this embodiment includes a pre-embedded structure shell and internal cable trough assemblies. Inside the pre-embedded structure shell, at least two parallel cable trough assemblies can be arranged according to construction and dimensional requirements. The number is not limited; therefore, this application only uses the arrangement of two cable trough assemblies inside the pre-embedded structure shell as an example for further explanation and illustration. Structures with multiple or even one cable trough assemblies inside are still within the protection scope of this application.

[0024] In this embodiment, the pre-embedded structure shell is divided into an upper pre-embedded structure shell 102 and a lower pre-embedded structure shell 101; the cable trough assembly is divided into an upper cable trough shell 202 and a lower cable trough shell 201; the cable trough assembly in this embodiment is used to construct a wiring channel 203, and the upper pre-embedded structure shell 102 and the lower pre-embedded structure shell 101 strengthen the protection of the internal cable trough assembly, improve its pressure resistance, and at the same time, it can realize the synchronous wiring of multiple cables, save wiring space, and reduce construction difficulty.

[0025] According to the actual wiring construction requirements, the pre-embedded structure in this embodiment is divided into a straight arrangement section and a transition section 3; wherein, the width of the pre-embedded structure matches the width of the excavated wiring trench 11, and the length of each straight arrangement section of the pre-embedded structure is 1000mm~2000mm.

[0026] Preferably, in this embodiment, two lower housings 201 with wire grooves are arranged side by side inside the lower housing 101 of the pre-embedded structure in the straight arrangement section of the pre-embedded structure. The lower housings 201 with wire grooves are arranged close to the inner wall of the corresponding side of the lower housing 101 of the pre-embedded structure, and a pre-embedded structure installation space 204 is reserved between the lower housing 201 with wire grooves and the corresponding inner wall. Inside the pre-embedded structure upper shell 102 of the straight-line arrangement section of the pre-embedded structure, there are parallel arrangement of the wire groove upper shell 202 that cooperate with the corresponding wire groove lower shell 201. The side wall of the wire groove upper shell 202 and the side wall of the pre-embedded structure upper shell 102 are integral structures, and the wall thickness of the pre-embedded structure upper shell 102 and the wire groove upper shell 202 at the cooperation position is greater than the wall thickness at other positions.

[0027] First, depending on the different structures of the straight section and the transition section 3, the arrangement direction of the internal cable trough assembly is also different. Specifically, as follows. This embodiment mainly strengthens the overall load-bearing capacity, especially the internal cable trough assembly, through the pre-embedded structural shell, i.e., structural strength. Firstly, since the upper cable trough shell 202 and lower cable trough shell 201 of the cable trough assembly in this embodiment are integrally formed with the pre-embedded structural upper shell 102 and lower pre-embedded structural shell 101 (or can be a separate structure for ease of installation and positioning), and the main load-bearing and stress-bearing structure is generally the pre-embedded structural upper shell, the pre-embedded structural upper shell 102 in this embodiment is divided into two parts: one part overlaps with the cable trough upper shell 202, and the other part does not overlap with the cable trough upper shell 202. These two parts have different thicknesses. Since the part overlapping with the cable trough upper shell 202 includes both the pre-embedded structural upper shell 102 and the cable trough upper shell 202, the thickness of this part is greater than the other parts. Therefore, this part can enhance the structural strength of the inner cable tray upper housing 202. At the same time, since there is no overlap with the cable tray upper housing 202, although the wall thickness is thin, this part does not act on the inner cable tray upper housing 202, so the force on this part will not affect the cable tray structure.

[0028] Preferably, the transition section 3 of the pre-embedded structure in this embodiment is configured as a T-shaped structure, which is divided into a first transition section 301 and a second transition section 302, with the first transition section 301 and the second transition section 302 arranged perpendicularly. Inside the pre-embedded structure lower housing 101 of the first transition section 301, two wire groove lower housings 201 are arranged side by side. The wire groove lower housings 201 are arranged close to the inner wall of the corresponding side of the pre-embedded structure lower housing 101, and a pre-embedded structure installation space 204 is reserved between the wire groove lower housing 201 and the corresponding inner wall. The second transition section 302 has two wire groove lower housings 201 arranged side by side inside the pre-embedded structure lower housing 101. The wire groove lower housings 201 are arranged close to the inner wall of the corresponding side of the pre-embedded structure lower housing 101, and a pre-embedded structure installation space 204 is reserved between the wire groove lower housing 201 and the corresponding inner wall. The area where the extension line of the lower housing 201 of the wire trough of the pre-embedded structure of the lower housing 101 of the first transition section 301 overlaps with the extension line of the lower housing 201 of the wire trough of the pre-embedded structure of the lower housing 101 of the second transition section 302 is a blank area 303. This blank area 303 is used to adjust the direction of the cable 4 when wiring in different directions. The upper shell 102 of the pre-embedded structure of the first transition section 301 has two wire groove upper shells 202 arranged side by side inside, and the upper shell 102 of the pre-embedded structure of the second transition section 302 has two wire groove upper shells 202 arranged side by side inside. The upper housing 202 of the cable trough mates with the corresponding lower housing 201 of the cable trough. The side wall of the upper housing 202 of the cable trough and the side wall of the upper housing 102 of the pre-embedded structure are an integral structure, and the wall thickness of the upper housing 202 of the pre-embedded structure and the upper housing 102 of the cable trough at the mating position is greater than the wall thickness at other positions.

[0029] This embodiment further defines the structure of the transition section 3, which is divided into a first transition section 301 and a second transition section 302. The two parts are perpendicular to each other, therefore, the internal cable tray assemblies are also arranged perpendicularly. The transition section 3 may have the following wiring methods: First, the two cables 4 in the straight section are routed by changing direction at a 90-degree angle through the transition section 3; Second, only the lower cable 4 needs to be routed at a 90-degree angle, while the other remains in a straight line. Based on these two wiring methods, the transition section 3 in this embodiment is designed as a T-shaped structure. This T-shaped transition section 3 satisfies both the requirements for straight wiring and the requirements for 90-degree angle wiring. Of course, other detailed requirements are still determined according to existing wiring requirements. For example, the turning diameter change required for 90-degree angle wiring determines the dimensions of the first transition section 301 and the second transition section 302 in this application. However, this application does not further constrain or limit the dimensions, but only provides the structure of the T-shaped transition section 3.

[0030] Meanwhile, due to the existence of the two wiring methods mentioned above, the cable located in the transition section 3 needs to meet both the requirements for straight-line layout and the requirements for 90-degree corner layout. Therefore, the cable tray assemblies in the first transition section 301 and the second transition section 302 also need to be arranged vertically. However, in order to avoid interference and to reserve a certain turning radius for 90-degree corner wiring, all overlapping areas are set inside in the form of blank areas 303. In this way, blank areas 303 can be used for straight-line wiring or 90-degree corner wiring.

[0031] Preferably, in this embodiment, an expansion bolt or anchor bolt 205 is provided at the pre-embedded structure installation space 204 of the pre-embedded structure lower shell 101, and the pre-embedded structure lower shell 101 is assembled and fixed to the ground or wall 10 by the expansion bolt or anchor bolt 205.

[0032] Preferably, the upper housing 202 of this embodiment includes an upper housing extension 20201 and an upper housing mounting portion 20202; a stepped surface is formed between the upper housing extension 20201 and the upper housing mounting portion 20202 to cooperate with the lower housing 201 of the wire trough. When the upper housing 202 of the cable trough is installed on the upper end of the lower housing 202 of the cable trough via the pre-embedded upper housing 102, the extension 20201 of the upper housing extends into the pre-embedded installation space 204, and the mounting part 20202 of the upper housing overlaps the end of the lower housing 201 of the cable trough. The lower housing 201 of the cable trough and the upper housing 202 of the cable trough are machined with a wedge-shaped groove at one end, and a sealing gasket 20203 is provided at the stepped surface. The sealing gasket 20203 is partially embedded in the wedge-shaped groove and partially extends into the pre-embedded installation space 204. The upper housing 202 of the cable trough is fixed to the upper end of the lower housing 201 of the cable trough by the snap-fit ​​of the sealing gasket 20203 and the wedge-shaped groove, and by the interference fit of the sealing gasket 20203 and the extension 20201 of the upper housing of the cable trough with the pre-embedded installation space 204.

[0033] First, in this embodiment, the upper and lower housings are installed using a snap-fit / interference fit between the wedge groove and the sealing gasket 20203. However, in practice, besides snap-fit ​​and interference fit, this embodiment can also be connected using fasteners. Snap-fit ​​and interference fit ensure both sealing and ease of installation. Therefore, this application does not specifically restrict the installation and connection methods. As an optional method, this embodiment can utilize all mating positions of the pre-embedded upper housing 102 and the pre-embedded lower housing 101 as connection points, relying on commonly used installation methods in the prior art. Similarly, the connection method between the upper housing 202 and the lower housing 201 of the wire trough in this embodiment can also be a conventional connection via a positioning snap-fit ​​structure on the end face. Since there are multiple connection methods, this application will not elaborate further.

[0034] As an extended implementation, a fastener connection structure can also be designed between the upper housing 102 and the lower housing 101 of the pre-embedded structure in this embodiment, so as to realize the assembly of the internal cable trough assembly through the upper housing 102 and the lower housing 101 of the pre-embedded structure.

[0035] To further facilitate the connection and installation of adjacent pre-embedded structures, a connection structure is provided between adjacent pre-embedded structures in this embodiment, so as to realize the connection between adjacent pre-embedded structures through the connection structure; The docking structure in this embodiment includes a protrusion formed at one end of the length direction of the pre-embedded structure shell and a groove 103 formed at the other end of the length direction of the pre-embedded structure shell. Adjacent pre-embedded structures are connected by inserting the protrusion into the adjacent groove 103 for positioning.

[0036] In addition, a U-shaped clip is provided in the aforementioned blank area 303 to secure the cables in that area.

[0037] This invention also discloses a construction method for a pre-embedded structure of cable troughs in electromechanical engineering construction. This construction method is based on the pre-embedded structure described above, and mainly includes the following steps: S100. Laying out and positioning: Determining the wiring location and direction of electrical equipment; S200. Based on the layout and positioning results, determine the number of straight sections and the number of transition sections 3, and at the same time determine the layout position of transition sections 3. S300. Excavate a wiring trench 11 of appropriate length and width, and remove impurities inside the wiring trench 11 to prepare for the pre-embedded structure. S400. Install the pre-embedded structure lower housing 101 into the wiring trough 11, and keep it aligned and parallel to the wiring trough 11. S500. Arrange the wires in the corresponding lower housing 201 of the pre-embedded structure lower housing 101, and install the pre-embedded structure upper housing 102, while keeping the upper housing 202 of the wire trough and the corresponding lower housing 201 of the wire trough. S600, pour the surface material layer to complete the wiring operation.

[0038] Furthermore, in step S500, when arranging cables in the lower housing 201 of the transfer section, U-shaped clips are used to reinforce and fix the cables in the blank area 303. Furthermore, the end of the transition section 3 that is not connected to the straight section is sealed by a steel plate.

[0039] The above technical solution provides a pre-embedded cable trough structure and its construction method for electromechanical engineering construction, which has the following beneficial effects: The cable trough pre-embedded structure of this invention is suitable for the synchronous arrangement of multiple parallel cables. The pre-embedded shell improves the structural strength and prevents deformation of the internal cable trough. At the same time, the integrated pre-embedded structure and the split pre-embedded structure can meet the use of different wiring requirements, with more application scenarios and meeting the wiring requirements of different construction locations. The overall structure is relatively novel, and the materials are mainly conventional metal materials. The manufacturing is not difficult, and the construction is convenient and flexible, which can reduce construction costs and simplify the construction process.

[0040] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
