Description

Technical Field

[0001] This invention relates to the field of building panel technology, specifically to a composite panel structure with fire-fighting pipes. Background Technology

[0002] In modern construction, composite slabs, as an important precast component, are widely used in various building structures. Composite slabs typically consist of precast slabs and cast-in-place concrete layers, offering advantages such as rapid construction and easy quality control. However, with the increasing complexity of building functions, the functional requirements for composite slabs are also rising. Especially in buildings requiring fire protection systems, how to rationally arrange fire protection piping within composite slabs while ensuring the safety and service life of these pipes has become a pressing issue.

[0003] Traditional composite slab structures often have the following shortcomings when arranging fire protection piping:

[0004] Firefighting pipes are susceptible to corrosion: Firefighting pipes are directly exposed to building materials and are easily corroded by building materials such as concrete, which can shorten the service life of the pipes and even cause safety hazards.

[0005] Inconvenient pipe connection: During the assembly of composite slabs, the connection of fire protection pipes often requires additional connectors and complicated construction steps, which increases the difficulty and cost of construction.

[0006] Poor pipeline stability: Fire protection pipelines lack effective fixing and limiting measures in composite slabs, making them prone to shaking or displacement during assembly and use, which affects the normal operation of the fire protection system. Summary of the Invention

[0007] The purpose of this invention is to provide a composite slab structure with fire-fighting pipes to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a composite slab structure with fire-fighting pipes, comprising a composite slab body, wherein a plurality of reserved grooves are formed on the surface of the composite slab body, a PCB sleeve is fixed inside the reserved grooves, a fire-fighting pipe is inserted and fixed inside the PCB sleeve, a plug is inserted at one end of the fire-fighting pipe, and a limit ring is fixed in the inner wall at the other end of the fire-fighting pipe, and a magnetic ring is embedded on the surface of the limit ring. When two sets of composite slab bodies with fire-fighting pipes installed are assembled end to end, the plug at the end of one set of composite slab bodies is inserted into the fire-fighting pipe at the end of the other set of composite slab bodies, and the plug at the end of one set of composite slab bodies is attracted to the magnetic ring at the end of the other set of composite slab bodies.

[0009] Preferably, the composite slab body is provided with multiple upper chord ribs on the top, and multiple web members are fixed between the upper chord ribs and the composite slab body. Furthermore, multiple prestressed steel bars are pre-embedded inside the composite slab body, and the length of the prestressed steel bars is greater than the length of the composite slab body.

[0010] Preferably, the reserved groove is a "U" shaped groove, the top of the PCB sleeve is fixed with a PCB limiting strip, the two sides of the PCB limiting strip are respectively fixed on two parallel side walls of the reserved groove, and the surface of the PCB limiting strip is provided with two sets of symmetrically distributed openings, the openings being triangular prisms.

[0011] Preferably, the length of the fire-fighting pipe is equal to the length of the composite slab body. One end of the fire-fighting pipe is provided with a side groove, which is an annular groove. A traction ring is movably inserted into the side groove and fixed to one end of the plug pipe. The end of the traction ring away from the plug pipe is provided with a receiving groove, which is an annular groove. Multiple elastic traction plates are fixed inside the receiving groove. The elastic traction plates are arc-shaped plates, and one end of the elastic traction plates is fixed to the surface of the side groove.

[0012] Preferably, a rubber cover is inserted and fixed inside one end of the traction ring, and one end of the rubber cover is fixed to the inner wall of the fire pipe.

[0013] Preferably, a retaining ring is fixed at the opening of the side groove. The inner diameter of the retaining ring is equal to the outer diameter of the plug tube. A frustum ring plate is integrally formed at the end of the plug tube away from the traction ring. The plug tube is fixed between the retaining ring and the traction ring. The plug tube has a circular tube structure.

[0014] Preferably, the retaining ring has an insert groove on the side away from the rubber cover. The insert groove is annular and a sealing ring is fixed inside the insert groove. The thickness of the sealing ring is greater than the depth of the insert groove.

[0015] Preferably, the surface of the limiting ring is provided with an insert groove 2, and the magnet ring is fixed in the insert groove 2, the thickness of the magnet ring being equal to the depth of the insert groove 2.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The composite slab structure with fire-fighting pipes proposed in this invention uses a pre-reserved groove on the surface of the composite slab body and a PCB sleeve fixed inside the pre-reserved groove. The fire-fighting pipe is inserted and fixed inside the PCB sleeve. The protective structure composed of the PCB sleeve and PCB limiting strip effectively prevents the fire-fighting pipe from being directly corroded by the building materials, thereby ensuring the service life of the fire-fighting pipe.

[0018] A plug is inserted into one end of the fire-fighting pipe, and components such as a traction ring and a rubber cover are installed on the plug. A limiting ring and a magnetic ring are installed at the other end of the fire-fighting pipe. When two composite slab bodies are assembled end-to-end, the plug is pushed into the fire-fighting pipe, and the rebound force of the rubber traction belt and elastic traction plate pulls the plug into the fire-fighting pipe of the other composite slab body, achieving rapid connection between the two sets of fire-fighting pipes. This connection method not only simplifies the construction steps but also reduces construction difficulty and cost.

[0019] By installing a retaining ring and a sealing ring at one end of the fire-fighting pipe, and a limiting ring and a magnetic ring at the other end, the plug pipe is effectively fixed and limited. When the plug pipe is inserted into the fire-fighting pipe of another set of composite slab bodies, the plug pipe will be attracted to the magnetic ring, thereby preventing the plug pipe from shaking randomly in the fire-fighting pipe and improving the stability of the fire-fighting pipeline.

They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8 This invention provides a technical solution: a composite slab structure with fire-fighting pipes, comprising a composite slab body 1, with multiple upper chord ribs 16 on the top of the composite slab body 1, multiple web members 17 fixed between the upper chord ribs 16 and the composite slab body 1, and multiple prestressed steel bars 18 pre-embedded inside the composite slab body 1, the length of the prestressed steel bars 18 being greater than the length of the composite slab body 1; multiple reserved grooves 2 are opened on the surface of the composite slab body 1, PCB sleeves 3 are fixed inside the reserved grooves 2, fire-fighting pipes 5 are inserted and fixed inside the PCB sleeves 3, the reserved grooves 2 are U-shaped grooves, PCB limiting strips 4 are fixed on the top of the PCB sleeves 3, the two sides of the PCB limiting strips 4 are respectively fixed on two parallel side walls of the reserved grooves 2, and the surface of the PCB limiting strips 4 has two sets of symmetrically distributed openings, the openings being triangular prisms. The PCB sleeve 3 and PCB limiting strip 4 form a protective structure for the fire pipe 5 in the reserved groove 2, which prevents the fire pipe 5 from being directly corroded by the building materials and ensures the service life of the fire pipe 5.

[0031] A plug tube 8 is inserted into one end of the fire pipe 5. A rubber cover 15 is inserted and fixed inside one end of the traction ring 7. One end of the rubber cover 15 is fixed to the inner wall of the fire pipe 5. A retaining ring 9 is fixed at the groove opening of the side groove 6. The inner ring diameter of the retaining ring 9 is equal to the outer ring diameter of the plug tube 8. A frustum ring plate is integrally formed at the end of the plug tube 8 away from the traction ring 7. The plug tube 8 is fixed between the retaining ring 9 and the traction ring 7. The plug tube 8 has a circular tube structure. An insert groove 10 is opened on the side of the retaining ring 9 away from the rubber cover 15. The insert groove 10 is an annular groove.

An embedding groove 20 is opened on the surface of the limiting ring 19. The magnetic ring 21 is fixed in the embedding groove 20. The thickness of the magnetic ring 21 is equal to the depth of the embedding groove 20. When the two sets of composite plate bodies 1 with fire pipes 5 are assembled end to end, the plug tube 8 at the end of one set of composite plate bodies 1 is inserted into the fire pipe 5 at the end of the other set of composite plate bodies 1. The plug tube 8 at the end of one set of composite plate bodies 1 is attracted to the magnetic ring 21 at the end of the other set of composite plate bodies 1, thereby preventing the plug tube 8 from shaking randomly in the fire pipe 5.
