Description

Technical Field

[0001] This utility model relates to the field of building component technology, specifically to an integrated conduit prefabricated floor slab. Background Technology

[0002] Prefabricated floor slabs with conduit channels are a type of precast building component. Their structure primarily consists of a load-bearing concrete layer and pre-installed conduit channels. The design location and size of these channels are determined according to actual needs, facilitating the subsequent laying of electrical and plumbing lines. These floor slabs are prefabricated in a factory using molds, and the conduit channels are pre-positioned during manufacturing to ensure their precision and robustness, thus achieving high-quality, standardized production. The assembly process includes three stages: design, manufacturing, and on-site installation. During the design stage, the channel locations are determined based on the building layout. The manufacturing stage involves prefabricating the floor slabs in the factory, ensuring that every detail meets design requirements. During on-site installation, precast floor slabs are hoisted into the building structure, spliced ​​and fixed according to predetermined positions, and pipelines are laid through channels. Construction workers only need to insert the pipelines into the channels and connect and debug them. For example, an integrated conduit prefabricated floor slab disclosed in authorization announcement number CN222667261U includes a floor slab body and a steel mesh. The steel mesh is located inside the floor slab body, with its ends extending outwards from the floor slab body. The surface of the floor slab body has at least one connection hole communicating with the pipeline. The pipeline is pre-installed inside the floor slab body, and the floor slab body has connections on its sides. The system has multiple recessed grooves, with the free end of the wiring conduit protruding from the floor slab body and located within these grooves. The wiring conduit is pre-embedded within the floor slab body, and recessed grooves are also provided on the side of the floor slab body. However, in practice, the floor slab body contains too many wiring conduits, and the reserved hole positions and dimensions are difficult to perfectly match the actual construction and pipeline routing during the design phase, easily leading to deviations. This results in the wiring holes being difficult to align precisely after multiple floor slabs are spliced, causing frequent occurrences of misaligned wiring holes. Utility Model Content

The square floor slab body has a fully penetrating wiring cavity 1 on the front and back sides and a fully penetrating wiring cavity 2 on the left and right sides. The left and right ends of two adjacent square floor slab bodies are connected by U-bolts, and the adjacent front and back square floor slab bodies are connected by a plate-type butt joint structure, thereby forming a connected wiring cavity 1 and wiring cavity 2, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated conduit prefabricated floor slab, comprising a square floor slab body, multiple U-bolts installed on the left outer wall of the square floor slab body, and multiple insertion holes opened on the right outer wall of the square floor slab body, the insertion holes being for the U-bolts to pass through; wiring cavities one are provided at the front and rear positions inside the square floor slab body, and wiring cavities two are provided at the left and right positions inside the square floor slab body; an upper boss is integrally formed at the top of the square floor slab body, and a row plate-type docking structure is provided on the front and rear outer walls of the upper boss, the row plate-type docking structure being used to connect two adjacent square floor slab bodies in the Y-axis direction.

[0005] Preferably, the left and right outer walls of the square floor slab body are provided with X-direction inlet holes that communicate with the first wiring cavity, and the front and rear outer walls of the square floor slab body are provided with Y-direction inlet holes that communicate with the second wiring cavity.

[0006] Preferably, the lower surface of the square floor slab body is provided with an upwardly extending concave cavity, and the vertical projection surfaces of the concave cavity and the upper protrusion overlap each other.

[0007] Preferably, two U-bolts are provided, and the two U-bolts are symmetrical about the vertical center reference plane of the square floor slab body.

[0008] Preferably, the bottom end of the square floor slab body is provided with an arc-shaped cutting groove concentric with the insertion hole, and the diameter of the arc-shaped cutting groove is larger than the diameter of the insertion hole.

[0009] Preferably, the plate-type docking structure includes a plurality of equally spaced square protrusions integrally formed on one side of the upper boss surface and an inner groove provided on the back of the upper boss.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This prefabricated floor slab with integrated conduit has a fully penetrating wiring cavity 1 on the front and back sides of the square floor slab body, and a fully penetrating wiring cavity 2 on the left and right sides. The left and right ends of two adjacent square floor slab bodies are connected by U-bolts, and the adjacent front and back square floor slab bodies are connected by a plate-type butt joint structure, thereby forming a connected wiring cavity 1 and wiring cavity 2, ensuring the alignment and unobstructed flow of the pipeline; wherein the multiple square floor slab bodies after connection are connected through the wiring cavity 1 and cavity 2, and the pipeline can be laid directly along the through cavity after the floor slab is manufactured, without the need for cumbersome pipeline drilling or adjustment on site, and the through cavity ensures the pipeline The continuity of the wiring reduces the risk of failure due to broken or misaligned pipes, facilitating later inspection and maintenance. Secondly, through the fully penetrating wiring cavity, the pipes can be smoothly laid out along the preset path, avoiding blockages or misalignments caused by inaccurate hole positions or excessive pipe bends in traditional designs. Furthermore, the continuity of the wiring ensures the rational layout of electrical and water pipes, reducing bends and connection points, thereby reducing pipe resistance and failure rate. At the same time, the row-plate docking structure and U-bolt connection between floor slabs ensure a stable connection between adjacent floor slabs, avoiding hole misalignment or pipe loosening caused by loose connections. This tight connection method not only improves the stability of the overall structure but also ensures the continuity and alignment of the through cavity. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0014] Please see Figure 1-7 An embodiment of this utility model is provided: an assembled floor slab with integrated conduit, including a square floor slab body 1, multiple U-bolts 4 installed on the left outer wall of the square floor slab body 1, and multiple insertion holes 5 opened on the right outer wall of the square floor slab body 1. The insertion holes 5 are for the U-bolts 4 to pass through. Wiring cavities 6 are provided at the front and rear positions inside the square floor slab body 1, and wiring cavities 8 are provided at the left and right positions inside the square floor slab body 1. An upper boss 2 is integrally formed at the top of the square floor slab body 1. A row plate-type docking structure 3 is provided on the front and rear outer walls of the upper boss 2. The row plate-type docking structure 3 is used to connect two adjacent square floor slab bodies 1 in the Y-axis direction. The square floor slab body 1 has X-direction inlet holes 101 on its left and right outer walls, which are connected to the wiring cavity 6. The X-direction inlet holes 101 on the left and right outer walls of the square floor slab body 1 keep the wiring cavity 6 open, allowing the pipeline to pass through the wiring cavity 6 and the X-direction inlet holes 101. The square floor slab body 1 has Y-direction inlet holes 102 on its front and rear outer walls, which are connected to the wiring cavity 8. The Y-direction inlet holes 102 keep the wiring cavity 8 open, allowing the pipeline to be arranged in the Y direction. The lower surface of the square floor slab body 1 is provided with an upwardly extending upper concave cavity 7. The vertical projection surfaces of the upper concave cavity 7 and the upper boss 2 coincide with each other. There are two U-bolts 4. The two U-bolts 4 are symmetrical about the vertical center reference plane of the square floor slab body 1. The bottom end of the square floor slab body 1 is provided with an arc-shaped cutting groove concentric with the insertion hole 5. The diameter of the arc-shaped cutting groove is larger than the diameter of the insertion hole 5. The end of the U-bolt 4 on the outer wall of one square floor slab body 1 is inserted into the insertion hole 5 on the outer wall of the other square floor slab body 1 so that the two square floor slab bodies 1 are bolted together. The plate-type docking structure 3 includes several equally spaced square protrusions 301 integrally formed on one side of the surface of the upper boss 2 and an inner groove 302 provided on the back of the upper boss 2. When multiple square floor slab bodies 1 are arranged and extended in the Y direction, the square protrusion 301 on one of the square floor slab bodies 1 is inserted into the inner groove 302 of the square floor slab body 1 until a stable docking is completed. The arrangement of multiple square protrusions 301 avoids uneven stress that may lead to an unstable connection or deformation.

[0015] In this embodiment, the first step is for staff to inspect the integrity and quality of all square floor slab bodies 1, U-bolts 4, and plate-type docking structures 3 beforehand, ensuring there are no damaged or missing parts. The construction area must be cleared beforehand to ensure a flat and clean surface, providing a good environment for the handling and positioning of the floor slabs. The first square floor slab body 1 is placed in the predetermined position, and a level, string, and markers are used to ensure the floor slab is level and accurately positioned. Then, the second square floor slab body 1 is gradually placed and docked with the first square floor slab body 1. At this point, staff need to pay special attention to aligning the wiring cavities 6 or 8 in the two square floor slab bodies 1 to ensure the through-cavities of the two floor slabs can be connected without obstruction. For the two square floor slabs 1 on the left and right, they are connected by U-bolts 4 and insertion holes 5. For the two adjacent square floor slabs 1 in front and behind, they are connected by a plate-type butt joint structure 3. During the entire butt joint process, the tightness and alignment of each connection point are repeatedly checked to ensure that there is no deviation. After the mechanical connection of multiple square floor slabs 1 is completed, the staff will lay the pipelines. Using the reserved wiring cavity 1 6 and wiring cavity 2 8, the wires, water pipes and other pipelines are laid along the through cavity according to the design requirements. When laying the pipelines, avoid excessive bending or compression of the pipelines to ensure the smooth and safe operation of the lines. After the pipelines are laid, the direction and connection points of the pipelines are checked again to ensure that there are no missing or incorrect connections.
