Description

Technical Field

[0001] This utility model belongs to the field of building industrialization and prefabricated building technology, specifically a prefabricated floor slab with a multi-functional embedded pipeline groove. Background Technology

[0002] In the construction industry, precast floor slabs are widely used due to their efficiency and economy. However, in actual projects, pipeline layout often requires post-construction grooving or external installation, which not only increases construction difficulty and cost but may also adversely affect the overall structural performance of the floor slab. Currently, some precast floor slabs with pre-embedded pipeline grooves are available on the market, but these designs typically fail to fully consider multifunctionality and compatibility, resulting in limited applicability. Furthermore, existing embedded pipeline grooves are mostly fixed structures, making it difficult to flexibly adjust them according to actual needs, and inaccurate positioning may occur during installation.

[0003] For example, the Chinese invention patent (application number: 202110567890.X) discloses a "precast floor slab with embedded pipeline grooves," the description of which states that it includes a floor slab body, within which several parallel embedded grooves are provided. These embedded grooves are fixedly connected to the floor slab's reinforcing steel frame via connectors. The openings of the embedded grooves are provided with detachable cover plates, which are connected to the floor slab body via a snap-fit ​​structure. This design can effectively reduce the subsequent grooving process and improve construction efficiency; however, the aforementioned patent also indicates that the existing technology has certain limitations in terms of the functional integration and structural flexibility of pipeline grooves.

[0004] Therefore, we have made improvements to this by proposing a precast floor slab with a multifunctional embedded pipeline groove. Utility Model Content

The locking operation of the fixing module is completed by aligning the pin with the pre-drilled hole on the steel reinforcement skeleton and inserting it.

[0010] As a preferred technical solution of this application, the inner wall of the main tank is provided with an elastic pad layer. The elastic pad layer is made of rubber material and has a thickness of 2mm to 5mm. The surface of the elastic pad layer is provided with anti-slip texture. The elastic pad layer is fixed to the inner wall of the main tank with adhesive to reduce the vibration and friction of the pipeline in the tank.

[0011] As a preferred technical solution of this application, the closed end cap of the branch channel is a detachable structure, and a sealing ring is provided on the inner side of the closed end cap. The sealing ring is made of silicone material and has a thickness of 1mm to 3mm.

[0024] like Figures 1 to 5 The present invention provides a precast floor slab with a multifunctional embedded pipeline groove. Its structure includes a floor slab body 1 and an embedded pipeline groove assembly, which consists of a groove module 2, an adjustment module 7, and a fixing module 10. The groove module 2 is located inside the floor slab body 1, the adjustment module 7 is connected to the groove module 2, and the fixing module 10 is located outside the adjustment module 7. Through the coordinated operation of these three components, the multifunctionality and flexible adjustment characteristics of the pipeline groove are achieved. The groove module 2 includes a main groove 3 and several branch grooves 4. The main groove 3 is a rectangular tubular structure with openings at both ends and a slide rail 5 extending along its length at the bottom. One end of each branch groove 4 is connected to the main groove 3, and the other end has a closed end cap. The bottom of each branch groove 4 has a slider 6 that matches the slide rail 5. The slider 6 is slidably connected to the slide rail 5, thereby allowing the branch groove 4 to be adjusted in position on the main groove 3.

[0025] The adjustment module 7 includes an adjustment rod 8 and a positioning component 9. One end of the adjustment rod 8 is fixedly connected to the bottom of the main channel body 3, and the other end passes through a pre-set hole on the floor slab body 1. The adjustment rod 8 is provided with a threaded section positioning component 9, including a nut and a washer. The nut engages with the threaded section of the adjustment rod 8, and the washer is located between the nut and the floor slab body 1. By rotating the nut, the adjustment rod 8 is driven to move the main channel body 3 vertically to adjust its height position. The fixing module 10 includes a fixing seat 11 and a locking component 12. The fixing seat 11 is located on the outside of the adjustment rod 8 and has a slot at the top. The slot engages with the steel reinforcement skeleton inside the floor slab body 1. The locking component 12 includes a pin and a spring. One end of the pin is inserted into the side wall of the fixing seat 11 and the other end is connected to the spring. The spring is located inside the fixing seat 11 to provide the pin's reset force. The locking operation of the fixing module 10 is completed by aligning the pin with the pre-reserved hole on the steel reinforcement skeleton and inserting it.

[0026] The inner wall of the main tank 3 is provided with an elastic pad with a thickness of 2mm to 5mm. The elastic pad is made of rubber material and has anti-slip texture on the surface. The elastic pad is fixed to the inner wall of the main tank with adhesive. The closed end cap of the branch tank 4 is a detachable structure. The inner side is provided with a silicone sealing ring with a thickness of 1mm to 3mm. The closed end cap is fixed to the branch tank 4 by threaded connection or snap connection. The slide rail 5 has scale marks on both sides. The scale marks are evenly distributed along the length of the slide rail 5, with the smallest unit being 1mm. The top of the main tank 3 is provided with a transparent protective cover plate 13. One side of the protective cover plate 13 is connected to the main tank 3 by a hinge, and the other side is fixed to the main tank 3 by a magnetic structure. The protective cover plate 13 is used to protect the pipeline inside the main tank 3 and facilitate the construction personnel to observe the pipeline layout.

[0027] In practical applications, when the channel module 2 is pre-installed inside the floor slab body 1, the number and spacing of the branch channels 4 are first determined according to the design requirements. The position of the branch channels 4 is adjusted by the cooperation of the slider 6 and the slide rail 5. The scale marks on the slide rail 5 can help to accurately adjust the spacing between the branch channels 4. After the adjustment is completed, the channel module 2 is fixed inside the floor slab body 1 by the locking piece 12. Then, one end of the adjusting rod 8 is fixedly connected to the bottom of the main channel 3, and the other end passes through the preset hole of the floor slab body 1 and is adjusted in height by the positioning piece 9. The nut in the positioning piece 9 cooperates with the threaded section of the adjusting rod 8. By rotating the nut, the adjusting rod 8 drives the main channel 3 to move in the vertical direction until the required height is reached. Finally, the slot of the fixing seat 11 is engaged with the steel reinforcement skeleton inside the floor slab body 1, and the pin of the locking piece 12 is inserted into the reserved hole on the steel reinforcement skeleton to complete the installation of the fixing module 10.

[0028] During pipeline layout, the protective cover 13 is opened and the pipeline is placed into the main trench 3 and the branch trench 4. The elastic padding layer can reduce the vibration and friction of the pipeline in the trench. The sealing ring of the closed end cap prevents external impurities from entering the interior of the branch trench 4. After the pipeline layout is completed, the protective cover 13 is closed and fixed by the magnetic structure. The entire installation process is simple to operate and can flexibly adjust the spacing of the branch trench 4 and the height of the main trench 3 according to actual needs, ensuring that the pipeline trench is structurally matched with the main floor slab 1, while improving the overall performance and construction efficiency of the precast floor slab.

[0029] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0030] During the installation of precast floor slabs, the channel module 2 must first be pre-embedded inside the main floor slab 1. The number and spacing of the branch channels 4 are determined according to the design requirements. The position of the branch channels 4 on the main channel 3 is adjusted by the cooperation of the slider 6 and the slide rail 5. The slide rail 5 has graduation marks on both sides, with a minimum unit of 1mm. Construction personnel can precisely adjust the spacing between the branch channels 4 according to the graduation marks to meet the needs of different pipeline layouts. After adjustment, the channel module 2 is fixed inside the main floor slab 1 using the locking device 12 to ensure that its position will not shift due to subsequent construction operations.

[0031] Subsequently, one end of the adjusting rod 8 is fixedly connected to the bottom of the main channel 3, and the other end passes through a pre-set hole on the floor slab body 1. The adjusting rod 8 has a threaded section on its outer side, and the nut in the positioning piece 9 engages with the threaded section of the adjusting rod 8. A washer is located between the nut and the floor slab body 1. By rotating the nut, the adjusting rod 8 moves the main channel 3 vertically until the height of the main channel 3 meets the design requirements. This process achieves precise height adjustment of the main channel 3, ensuring the structural compatibility between the pipeline trough and the floor slab body 1.

[0032] Next, the slot of the fixing seat 11 is engaged with the steel reinforcement skeleton inside the floor slab body 1, and the fixing module 10 is locked using the locking member 12. One end of the pin in the locking member 12 is inserted into the side wall of the fixing seat 11, and the other end is connected to a spring, which is located inside the fixing seat 11 to provide a restoring force. When the pin is aligned with the reserved hole on the steel reinforcement skeleton and inserted, the fixing module 10 can firmly fix the embedded pipeline groove assembly in the floor slab body 1, preventing loosening or displacement caused by external forces.

[0033] During the pipeline installation phase, construction workers open the protective cover 13 and place the pipelines into the main trench 3 and branch trench 4. The inner wall of the main trench 3 is equipped with an elastic pad, 2mm to 5mm thick, made of rubber with an anti-slip texture. The elastic pad is fixed to the inner wall of the main trench with adhesive, effectively reducing vibration and friction of the pipeline within the trench, thereby extending the pipeline's service life. The inner side of the closed end cap of the branch trench 4 is equipped with a silicone sealing ring, 1mm to 3mm thick. The sealing ring is fixed to the branch trench 4 via threaded or snap-fit ​​connections, preventing external impurities from entering the branch trench 4 and ensuring a clean pipeline installation environment.

[0034] After the pipeline layout is completed, the construction personnel close the protective cover 13 and fix it in place using a magnetic structure. The protective cover 13 is made of transparent material, allowing construction personnel to easily observe the pipeline layout at any time, while protecting the pipelines inside the main trench 3 from external damage. The entire installation process is simple to operate, and the spacing of the branch trenches 4 and the height of the main trench 3 can be flexibly adjusted according to actual needs, thereby ensuring the structural compatibility between the pipeline trench and the main floor slab 1.

[0035] Through the above steps, the precast floor slab with multifunctional embedded pipeline grooves of this utility model achieves a multifunctional integrated design of pipeline grooves. The main groove 3 and branch groove 4 in the groove module 2 achieve flexible adjustment of the position of the branch groove 4 through the cooperation of the slide rail 5 and the slider 6; the adjustment module 7 achieves precise adjustment of the height of the main groove 3 through the coordinated action of the adjustment rod 8 and the positioning component 9; the fixing module 10 ensures the stable installation of the embedded pipeline groove assembly through the cooperation of the fixing seat 11 and the locking component 12. These technical means effectively solve the problems of single function, fixed structure, and inaccurate installation positioning of pipeline grooves in the prior art, while improving the overall performance and construction efficiency of the precast floor slab.
