Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a type of steel-concrete composite beam with electromechanical pipelines. Background Technology

[0002] In the construction of core tube structures for super high-rise buildings, insufficient clearance caused by pipework conflicts has long constrained spatial quality. As the central hub bearing vertical loads and electromechanical systems, the dimensions of its connecting beams and ring beams are limited by structural stiffness and cannot be easily adjusted. Furthermore, when electromechanical pipelines such as ventilation ducts, fire water pipes, and cable conduits need to pass through the core tube walls, traditional pre-embedding methods often result in compressed clearance in areas where pipelines are concentrated. The designed clearance height of the core tube elevator lobby is typically 2.8-3.0 meters; however, due to the influence of pipeline intersections, the actual measured clearance height can easily drop below 2.5 meters, which not only fails to meet fire safety regulations for evacuation routes but also reduces the building's usability.

[0003] There are currently three construction methods: Increasing the size of the core tube ring beam and reinforcement will increase costs while reducing the usable space below. Sacrificing some room height to ensure the effect of rooms with more important features, such as elevator halls, will reduce the utilization rate of the area and increase unnecessary openings; Lowering the ceiling height requirement for fully furnished apartments will directly reduce the delivery standards and the usable space, thus affecting the usable space. Utility Model Content

[0004] The purpose of this utility model is to provide a component that allows pipelines to pass through without reducing the lower clearance. Specifically, by setting several pipelines on the core tube ring beam, it is possible to allow pipelines to pass through without reducing the lower clearance, and without having to lower the design elevation of the core tube elevator hall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steel-concrete composite beam with electromechanical pipelines is characterized by comprising an I-shaped steel frame and a plurality of embedded pipe assemblies passing through the web of the I-shaped steel frame. The embedded pipe assemblies include connecting pipes prefabricated on the I-shaped steel frame and prefabricated pipe bodies. The prefabricated pipe bodies are provided with cover plate assemblies for preventing concrete from entering the prefabricated pipe bodies. The cover plate assemblies include cover plate bodies located at the pipe openings on both sides of the prefabricated pipe bodies and connectors for connecting the cover plate bodies on both sides.

[0006] More preferably, the cover plate body is made of thin PVC or PE material.

[0007] Furthermore, the connector includes an internally threaded sleeve and an externally threaded screw, wherein the externally threaded screw is screwed into the internally threaded sleeve to tighten the cover plates on both sides.

[0008] Furthermore, the internally threaded sleeve is a solid structure with an internally threaded hole.

[0009] Furthermore, the cover plate body used to fix the internal threaded sleeve is provided with a knob groove, the knob groove extends into the internal threaded sleeve, and the bottom of the knob groove is provided with a cross-shaped limiting groove for connecting a knob tool.

[0010] Furthermore, the knob groove is provided with a sealing cover at the opening on the cover plate body.

[0011] In addition, the beam body also includes studs, longitudinal bars, stirrups and web bars, with the stirrups and web bars being set close to the precast pipe body.

[0012] More preferably, the cover plate body and the connecting parts are all made of stainless steel.

[0013] Compared with the prior art, this utility model has the following features and beneficial effects: This application pre-embeds pipe components in the web of a concrete beam steel structure. The overall component can meet both structural requirements and the requirements for the passage of electromechanical pipelines. The pre-embedded pipe components have a cover plate body to prevent concrete from entering. The cover plate body is easy to disassemble. Compared with the existing technology that uses plastic bags to tie the pipe, the concrete at the pipe outlet is more regular and there is no need to add concrete later. It has the characteristics of safety and applicability, and has good promotion and practical value. After widespread promotion and application, it will generate good economic benefits.

[0017] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0018] Example 1 A type of steel-concrete composite beam with electromechanical pipelines, such as Figures 1-3 As shown, the device includes an I-beam-shaped steel frame 1 and several embedded pipe assemblies 2 passing through the web of the I-beam-shaped steel frame 1. The embedded pipe assembly 2 includes a connecting pipe 21 prefabricated on the I-beam-shaped steel frame 1 and a prefabricated pipe body 22. The prefabricated pipe body 22 is provided with a cover plate assembly for preventing concrete from entering the prefabricated pipe body 22. The cover plate assembly includes a cover plate body 23 located at the pipe openings on both sides of the prefabricated pipe body 22, and a connector 24 for connecting the two cover plate bodies 23. The connecting pipe 21 and the web of the I-beam-shaped steel frame 1 are prefabricated together in the factory. The connecting pipe 21 strengthens the support of the prefabricated pipe body 22 and enhances the stability of the prefabricated pipe body 22. The cover plate body 23 and the connector 24 are both made of stainless steel.

[0019] Example 2 Based on Embodiment 1, the cover plate body 23 is made of thin PVC or PE material. The cover plate body abuts against the template to prevent concrete from entering the precast pipe body. The connector 24 includes an internal threaded sleeve and an external threaded screw. The external threaded screw is screwed into the internal threaded sleeve to tighten the cover plate bodies 23 on both sides. The internal threaded sleeve is a solid structure with internal threaded holes.

[0020] Example 3 Based on Embodiment 1, the cover plate body 23 for fixing the internal threaded sleeve is provided with a knob groove 25.

The opening of the knob groove 25 on the cover plate body 23 is provided with a sealing cover 26. The beam also includes studs 11, longitudinal bars 12, stirrups 13 and waist bars 14. The stirrups 13 and waist bars 14 adjacent to the prefabricated pipe body 22 are set close to the prefabricated pipe body 22 and are fixed by electric welding as needed. Specifically, if the prefabricated pipe body 22 is thin and long, spot welding can be considered for fixing.

[0021] After dismantling the concrete beam formwork, open the sealing cover 26 and insert the knob tool into the cross-shaped limiting groove. Turn the knob to separate the internal thread sleeve and the external thread screw, that is, separate the cover plate body 23 and the cover plate body 23.
