Description

Technical Field

[0001] This utility model relates to a sleeve mechanism that penetrates a concrete component, which is fixedly installed inside the concrete component to form a precise connection with the corresponding cable tray. Background Technology

[0002] like Figure 1 As shown, in order to make better use of the space height, when cable trays pass through structural beams (concrete components), holes are usually drilled in the structural beams. The cable trays are then supported by horizontal bars fixed to the bottom of the holes, and the cables installed in the cable trays are laid through the holes.

[0003] While drilling holes in structural beams and installing crossbars can make good use of space and height, the resulting seams between the drilled holes and the cable trays can allow small animals to crawl in, potentially damaging the cables or causing the animals' death. Furthermore, structural components that isolate the cable trays disrupt the grounding function of the trays; moreover, simply drilling holes can significantly damage the load-bearing capacity of the structural beams.

[0004] Therefore, the research objective of this utility model is to design a sleeve mechanism that can both reduce the impact on the stress performance of structural beams and effectively form a closed installation connection to prevent small animals from entering and maintain a continuous grounding connection through concrete components. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a sleeve mechanism that penetrates concrete components, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A sleeve mechanism penetrating a concrete member, comprising:

[0008] The post-installed component is installed inside the corresponding concrete component after drilling a hole at an appropriate position in the concrete component. The post-installed component includes a connecting part that is arranged in a tubular shape and a docking part that is connected to the outside of the connecting part. The docking part is arranged in a tubular shape and the diameter of the docking part is larger than that of the connecting part.

[0009] The connector is tubular and can be detachably installed to the connecting part of the rear component via a threaded connection. A corresponding limiting flange is fixed to the outer side of the connector. After the connector is connected to the connecting part of the rear component, the limiting flange is fixedly abutted against the end face of the concrete component.

[0010] A set of mounting components are respectively fixed to the docking portion of the rear component and the outer end of the connecting component. One end of the set of mounting components not connected to the docking portion and the connecting component is respectively set to a shape adapted to the corresponding cable tray. Furthermore, the set of mounting components is respectively provided with guide holes that connect the docking portion, the connecting component and the cable tray.

[0011] One set of the mounting components is not connected to the docking part, and one end of the connecting component is respectively fixed to a corresponding docking ring plate. The cable tray is locked to the docking ring plate by multiple sets of docking bolts.

[0012] The docking part is integrally formed and connected to the connecting part, and the connection between the docking part and the connecting part is arranged in an arc shape.

[0013] The limiting flange is fixed to the connector by welding, and a set of threaded holes for mounting the rotating handle are provided on the outer side of the limiting flange.

[0014] A corresponding sealing rubber gasket is fixed to the side of the limiting protrusion near the concrete component.

[0015] The mounting component is fixed to the mating portion of the rear component and the outer end of the connecting component by welding.

[0016] Advantages of this utility model:

[0017] 1) The rear-mounted component of this utility model is installed inside the concrete component after a hole is drilled at an appropriate position. It is then connected to the component via a connector. Because the diameter of the connecting portion of the rear-mounted component is larger than that of its connecting portion, and because a limiting flange is fixedly attached to the outer side of the connector, the limiting flange abuts against the end face of the concrete component after the connector is connected to the connecting portion of the rear-mounted component. This effectively forms a locking mechanism using a counterforce, ensuring the overall stability of the rear-mounted component and the connector. Furthermore, the support of the rear-mounted component and the connector effectively compensates for the strength loss caused by the hole in the structural beam. This reduces the impact on the structural beam's load-bearing capacity. Combined with the cable tray, it forms a connecting component, effectively creating a closed installation and preventing small animals from entering, thus significantly improving the usability of this utility model.

[0018] 2) This utility model achieves a locking connection between the docking part, the connecting part and the cable tray by the intervention of a set of installation parts, thereby effectively ensuring the practical effect of this utility model.

[0019] 3) The limiting protrusion of this utility model has a set of threaded holes for mounting a rotary handle on its outer side. During the rotation installation of the connector, the rotary handle with external threads can be detachably installed onto the threaded holes for mounting the rotary handle, so as to facilitate the rotation operation of the connector and thus ensure the ease of construction of this utility model. After the rotation operation is completed, the rotary handle with external threads can be removed. Attached Figure Description

[0024] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0025] refer to Figure 2-3 A sleeve mechanism penetrating a concrete member, comprising:

[0026] The post-installed component 1 is installed in the corresponding concrete component 2 after drilling a hole at an appropriate position in the concrete component. The post-installed component 1 includes a connecting part 101 arranged in a tubular shape and a docking part 102 connected to the outside of the connecting part 101. The docking part 102 is arranged in a tubular shape and the diameter of the docking part 102 is larger than that of the connecting part 101.

[0027] The connector 3 is tubular and can be detachably installed to the connecting part 101 of the rear component 1 via a threaded connection. A corresponding limiting flange 301 is fixedly connected to the outer side of the connector 3. After the connector 3 is connected to the connecting part 101 of the rear component 1, the limiting flange 301 is fixedly abutted against the end face of the concrete component 2.

[0028] A set of mounting parts 4 are respectively fixed to the docking part 102 of the rear part 1 and the outer end of the connecting part 3. One end of the set of mounting parts 4 that is not connected to the docking part 102 and the connecting part 3 are respectively set to a shape that is adapted to the corresponding cable tray 5. And the set of mounting parts 4 are respectively provided with guide holes 401 that connect the docking part 102, the connecting part 3 and the cable tray 5.

[0029] The rear-mounted component 1 of this invention is installed inside the corresponding concrete component 2 after a hole is drilled at an appropriate position in the concrete component. It is then connected to the rear-mounted component 1 via a connecting component 3. Since the diameter of the connecting portion 102 of the rear-mounted component 1 is larger than that of its connecting portion 101, and a limiting flange 301 is fixedly attached to the outer side of the connecting component 3, the limiting flange 301 is fixedly abutted against the end face of the concrete component 2 after the connecting component 3 is connected to the connecting portion 102 of the rear-mounted component 1. This effectively forms a locking fixation using the reverse force, ensuring the overall stability of the installation of the rear-mounted component 1 and the connecting component 3. Furthermore, the support of the rear-mounted component 1 and the connecting component 3 effectively compensates for the strength loss caused by the opening in the structural beam. This reduces the impact on the structural beam's load-bearing performance while forming a connecting component with the cable tray, effectively creating a closed installation and preventing small animals from entering, thus significantly improving the usability of this invention.

[0030] A set of mounting components 4, not connected to the docking part 102, has corresponding docking ring plates 6 fixedly attached to one end of the connecting component 3. Multiple sets of docking bolts 7 are used to lock the cable tray 5 onto the docking ring plates 6. The docking part 102 is integrally formed and connected to the connecting part 101, and the connection between the docking part 102 and the connecting part 101 is arc-shaped. The intervention of the mounting components 4 achieves a lockable connection between the docking part 102, the connecting component 3, and the cable tray 5, thereby effectively ensuring the practical effect of this invention.

[0031] The limiting flange 301 is fixed to the connector 3 by welding, and a set of threaded holes 3011 for mounting the rotary handle are provided on the outer side of the limiting flange 301. During the rotation installation of the connector 3, the rotary handle with external threads can be detachably installed into the threaded holes 3011 for mounting the rotary handle, so as to facilitate the rotation operation of the connector 3 and thus ensure the ease of construction of this utility model. After the rotation operation is completed, the rotary handle with external threads can be removed.

[0032] A corresponding sealing rubber gasket 8 is fixedly connected to the side of the limiting protrusion 301 near the concrete component 2. With the intervention of the sealing rubber gasket 8, the connection and closure effect between the limiting protrusion 301 and the concrete component 2 can be further effectively ensured, thereby overcoming the problem of uneven surface of the concrete component 2.

[0033] The mounting component 4 is fixed to the docking portion 102 of the rear component 1 and the outer end of the connecting component 3 by welding.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
