Technical Field
[0001] This invention relates to the field of prefabricated decoration technology, specifically to a prefabricated elevated ground and pipeline integrated structure and its manufacturing method. Background Technology
[0002] Prefabricated decoration, with "factory prefabrication + on-site assembly" as its core, achieves efficient and environmentally friendly interior construction through SI separation technology (separation of structure and interior decoration, separation of structure and pipelines), modular product design, and dry construction. Its core advantages include shortened construction period, controllable quality, and green energy saving.
[0003] Traditional floor decoration involves a large amount of wet work on-site and a long construction period. Pipeline construction often involves cutting grooves in the floor slab, which reduces the floor slab thickness and lowers the floor slab's sound insulation performance and safety. On the other hand, existing prefabricated raised floors focus more on the raised floor structure itself and do not study the integration and organization of pipelines in depth enough, which can easily lead to disordered pipeline crossings and tangled pipelines.
[0004] Therefore, it is necessary to develop a prefabricated elevated ground and pipeline integrated structure and its manufacturing method to organically combine the two and better promote the development and application of prefabricated decoration. Summary of the Invention
[0005] The purpose of this invention is to provide a prefabricated raised floor and pipeline integrated structure and its manufacturing method, which solves the following technical problems: traditional floor decoration involves a large amount of wet work on site and a long construction period. Pipeline construction often involves slotting in the floor slab, which reduces the floor slab thickness and lowers the floor slab's sound insulation performance and safety. Existing prefabricated raised floors focus more on the raised floor structure itself and do not conduct in-depth research on pipeline integration and organization, which easily leads to disordered pipeline crossing and pipeline confusion.
[0006] The objective of this invention can be achieved through the following technical solutions: A prefabricated elevated ground and pipeline integrated structure includes a prefabricated elevated frame. The prefabricated elevated frame includes several point supports arranged in a longitudinal and transverse array. Each point support includes a bottom support fixedly installed on the ground. A vertically perforated rectangular tube A is inserted into the bottom support, and a vertically perforated rectangular tube B is slidably inserted into the vertically perforated rectangular tube A. At least two upper horizontal keel support components are assembled on the multiple vertically perforated rectangular tubes B, and decorative horizontal keels are inserted between two adjacent upper horizontal keel support components with a gap fit. The top surface of the decorative horizontal keel is covered with composite floor decoration material. In the prefabricated overhead frame, at least any two vertically perforated rectangular tubes B that are symmetrically distributed are equipped with lower horizontal keel support members, and the lower horizontal keel support members are located below the upper horizontal keel support members. The same pipeline horizontal keel is inserted between two adjacent lower horizontal keel support members. The top surface of the pipeline horizontal keel is provided with multiple elongated holes at equal intervals, and at least one of the elongated holes is inserted with a dotted pipe clamp.

[0008] As a further aspect of the present invention: the surfaces of the vertically perforated rectangular tube A and the vertically perforated rectangular tube B are provided with a plurality of mounting holes at equal intervals; At one end of both the upper and lower horizontal keel support components, four small cylinders adapted to the size of the mounting holes are fixedly provided.
[0009] As a further aspect of the present invention: the two ends of the decorative horizontal keel are provided with round holes, and a top surface limiting block is assembled in the round holes.
[0010] As a further aspect of the present invention, the bottom support is fixedly mounted on the ground using special adhesive.
[0011] As a further aspect of the present invention: the upper horizontal keel support member is symmetrically provided with sliding grooves, and the two sides of the decorative horizontal keel are fixedly provided with sliders adapted to the sliding grooves, and the sliding grooves and the sliders are connected by a gap insertion method. The connection structure and connection method between the lower horizontal keel support component and the pipeline horizontal keel are the same as the connection structure and connection method between the upper horizontal keel support component and the decorative horizontal keel.
[0012] As a further aspect of the present invention, an indicator port is provided around the bottom support.
[0013] As a further aspect of the present invention: the top of the decorative horizontal keel is provided with a vertical profile for limiting the side of the composite floor decoration material.
[0014] As a further aspect of the present invention: the top surface limiting block is placed on top of the vertically perforated rectangular tube B.
[0015] A method for manufacturing a prefabricated elevated ground and pipeline integrated structure, using the aforementioned prefabricated elevated ground and pipeline integrated structure, includes the following specific steps: S1. After the floor slab is laid out, the installation position of the point support is determined according to the drawings. Then, special glue is applied to the bottom surface of the bottom support and fixed to the ground. Then, the vertically perforated rectangular tube A is inserted into the groove of the bottom support with a gap. Then, the vertically perforated rectangular tube B is slidably inserted into the vertically perforated rectangular tube A. After sliding adjustment to the design height, the small cylinder at the end of the upper horizontal keel support component is inserted into the installation hole at the overlapping part of the two to complete the fixing of the vertical support component and the upper horizontal keel support component. S2. Between two adjacent upper horizontal keel support components, the decorative horizontal keel is installed by interlocking the groove and the slider. At the same time, the top limiting block is installed in the round hole at both ends of the decorative horizontal keel so that it is placed on the top of the vertically perforated rectangular tube B to achieve precise limiting and fixing. S3. According to the pipeline design, insert the lower horizontal keel support components on the corresponding multiple small cylinders, install the pipeline horizontal keel between two adjacent lower horizontal keel support components, and then insert the point-type pipe clamps into the elongated holes on the top surface of the pipeline horizontal keel according to the pipeline layout requirements to complete the pipeline fixing structure construction. S4. Lay composite floor decoration material within the rectangular area enclosed by the horizontal keel of the decorative surface, and use the vertical profiles at the top of the horizontal keel of the decorative surface to limit the side edges of the decorative material.
[0016] The beneficial effects of this invention are: (1) Significant advantages in construction and environmental protection: This invention adopts prefabricated integrated technology, which completely avoids the on-site wet operation and floor slab grooving operation of traditional floor decoration.

(2) Efficient and precise installation and adjustment: The present invention can achieve precise adjustment of ground height through the insertion and sliding fit of vertically perforated rectangular tube A and vertically perforated rectangular tube B and the design of fixed spacing holes; the upper and lower horizontal keel support components can be quickly inserted and fixed without bolt welding due to the precise correspondence between the small cylindrical back and the rectangular tube holes, which further improves construction efficiency and greatly reduces the labor cost on the construction site. (3) Flexible and orderly pipeline layout: This invention relies on the fixed spacing of the pipeline horizontal keel and the flexible insertion of the elongated hole and the point-type pipe clamp, combined with the combination and adaptation of the lower horizontal keel support components, so that the pipeline position can be flexibly adjusted according to the actual needs of the project, effectively solving the problem of disordered intersection and confusion of traditional and existing prefabricated ground pipelines, while realizing the reversible disassembly and assembly of the structure, which is convenient for later maintenance and modification.

[0023] In the field of prefabricated decoration technology, traditional floor decoration generally suffers from prominent problems such as numerous wet construction processes, long construction cycles, and damage to structural safety due to floor slab grooving. Meanwhile, existing prefabricated raised floor technology faces drawbacks such as insufficient pipeline integration planning, which can easily lead to disordered pipeline layout. Therefore, this paper proposes a prefabricated raised floor and pipeline integration structure and its manufacturing method, aiming to provide technical support for promoting the efficient development of the prefabricated decoration industry.
[0024] Example 1: Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, a prefabricated elevated ground and pipeline integrated structure includes a prefabricated elevated frame, which includes several point supports 1 arranged in a longitudinal and transverse array. Each point support 1 includes a bottom support 7 fixed to the base ground with special adhesive. The top of the bottom support 7 has a slot 14, into which a vertically perforated rectangular tube A8 is inserted with a clearance fit. The lower end face of the vertically perforated rectangular tube A8 is adapted to the slot 14, achieving rapid positioning and stable connection between the two. A vertically perforated rectangular tube B9 is slidably inserted onto the vertically perforated rectangular tube A8. After the floor slab is laid out on the construction site, the installation position of the point support 1 is determined according to the drawings. Special glue is applied to the bottom support 7 and fixed to the base floor. The vertically perforated rectangular tube A8 is inserted into the groove 14 at the top of the bottom support 7, and then the vertically perforated rectangular tube B9 is inserted into the vertically perforated rectangular tube A8.
[0025] For details, please refer to Figure 3 As shown, indicator ports 13 are provided around the bottom support 7 to ensure that the bottom support 7 is consistent with the direction of the line laying. By setting an indicator port 13 on the bottom support 7 and fixing it to the ground with special adhesive, the installation accuracy of the support is improved and the original ground is avoided from being damaged by screws and anchors.
[0026] For details, please refer to Figure 6As shown, the vertically perforated rectangular tubes A8 and B9 have multiple mounting holes 15 evenly spaced along their length. During assembly, the vertically perforated rectangular tubes A8 and B9 are combined by nesting and plugging, and can slide relative to each other vertically to adjust the overall height. After the height is adjusted to the design requirements, the upper horizontal keel support member 201 and the lower horizontal keel support member 202 are engaged with the mounting holes 15 at the corresponding positions to complete the quick positioning and locking of the three components, achieving precise height fixation.
[0027] For details, please refer to Figure 7 As shown, at least two upper horizontal keel support components 201 are assembled on multiple vertically perforated rectangular tubes B9; For details, please refer to Figure 8 , Figure 9 As shown, the same decorative horizontal keel 3 is inserted between two adjacent upper horizontal keel support members 201 with a gap fit. The upper horizontal keel support member 201 has symmetrically opened grooves 17 inside. The decorative horizontal keel 3 has sliders 18 that are adapted to the grooves 17 fixed on both sides. The connection between the upper horizontal keel support component 201 and the decorative horizontal keel 3 is achieved by the sliding engagement of the slide groove 17 and the slider 18.
[0028] For details, please refer to Figure 1 , Figure 11 As shown, in the prefabricated overhead frame, at least any two vertically perforated rectangular tubes B9 that are symmetrically distributed are equipped with lower horizontal keel support members 202, and the lower horizontal keel support members 202 are located below the upper horizontal keel support members 201. Considering that the location and direction of pipelines need to be adjusted and optimized according to the design plan during on-site installation, the two symmetrically arranged lower horizontal keel support components 202 can be flexibly installed in any position inside the prefabricated overhead frame, and their quantity can also be adjusted according to actual needs.
[0029] For details, please refer to Figure 8 As shown, one end of the upper horizontal keel support component 201 and the lower horizontal keel support component 202 is fixed with four small cylinders 16 that are adapted to the size of the mounting holes 15. The arrangement position and spacing of the four small cylinders 16 correspond one-to-one with the mounting holes 15 on the vertically perforated rectangular tube A8 and the vertically perforated rectangular tube B9, so as to realize quick plug-in assembly.
[0030] During installation, after adjusting the height of the sliding connection between the vertically perforated rectangular tube A8 and the vertically perforated rectangular tube B9, insert the four small cylinders 16 at one end of each upper horizontal keel support component 201 or lower horizontal keel support component 202 into the four mounting holes 15 on different sides of the overlapping part of the vertically perforated rectangular tube A8 and the vertically perforated rectangular tube B9, respectively, to form a stable insertion fit, thereby completing the fixed connection between the horizontal keel support component and the vertically perforated rectangular tube A8 and the vertically perforated rectangular tube B9.
[0031] For details, please refer to Figure 1 , Figure 10 As shown, round holes 19 are provided on both ends of the decorative horizontal keel 3. A top surface limiting block 10 is installed in the round hole 19, and the top surface limiting block 10 is placed on the top of the vertically perforated rectangular tube B9. Through the precise correspondence between the round hole 19 and the top limiting block 10, the two sides of the horizontal keel support component 2 are inserted into the horizontal keel support component 2, and the three are organically combined to achieve fast and precise installation.
[0032] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 11 As shown, the same pipeline horizontal keel 4 is inserted between two adjacent lower horizontal keel support members 202. The pipeline horizontal keel 4 is placed directly below the decorative horizontal keel 3. The insertion method of the lower horizontal keel support member 202 and the pipeline horizontal keel 4 is the same as the insertion method of the upper horizontal keel support member 201 and the decorative horizontal keel 3. The connection between the two is completed by the cooperation of the sliding groove 17 and the sliding block 18.
[0033] When laying pipelines, according to the on-site construction drawings and the location of the pipelines, the pipeline horizontal keel 4 can be flexibly arranged between any two lower horizontal keel support members 202 of the prefabricated overhead frame. After the specific location is determined, the lower horizontal keel support member 202 is inserted into the corresponding mounting holes 15 in the vertically perforated rectangular tube A8 and vertically perforated rectangular tube B9 for fixing. Then, the two sides of the pipeline horizontal keel 4 are inserted into the lower horizontal keel support member 202 with clearance fit.
[0034] For details, please refer to Figures 11-13 As shown, multiple elongated holes 11 are equally spaced on the top surface of the pipeline cross keel 4, and at least one elongated hole 11 is fitted with a dotted pipe clamp 5. Based on the actual needs of pipeline installation, multiple point-type pipe clamps 5 can be quickly and flexibly inserted into different elongated holes 11 on the pipeline cross beam 4.
[0035] For details, please refer to Figure 1 As shown, the top surface of the decorative horizontal keel 3 is covered with composite floor decoration material 6. The four decorative horizontal keels 3 form a rectangular structure, which together support the same piece of composite floor decoration material 6.
[0036] For details, please refer to Figure 1 , Figure 10 As shown, a vertical profile 12 is provided at the top of the decorative horizontal keel 3. The vertical profile 12 is used to limit the side edge of the composite floor decoration material 6, which can quickly place the decoration material.
[0037] Example 3: This invention also discloses a method for manufacturing a prefabricated elevated ground and pipeline integrated structure, comprising the following steps: S1. Base positioning and vertical support assembly: After the floor slab is laid out, the installation position of the point support 1 is determined according to the drawings. Special glue is applied to the bottom surface of the bottom support 7 and it is fixed to the ground. The indicator ports 13 around the bottom support 7 are used to ensure that they are consistent with the laying direction. Then, the vertically perforated rectangular tube A8 is inserted into the slot 14 of the bottom support 7 with gaps. Then, the vertically perforated rectangular tube B9 is slidably inserted into the vertically perforated rectangular tube A8. After adjusting the two to the design height, the small cylinder 16 at the end of the upper horizontal keel support component 201 is inserted into the mounting hole 15 of the overlapping part of the two to complete the fixing of the vertical support component and the upper horizontal keel support component 201. S2. Installation of decorative horizontal keel and formation of ground frame: Decorative horizontal keel 3 is installed between adjacent upper horizontal keel support components 201 through the gap between sliding groove 17 and slider 18 to form ground support frame; at the same time, top surface limiting block 10 is installed in the round hole 19 at both ends of decorative horizontal keel 3, so that it is placed on the top of vertical opening rectangular tube B9 to achieve precise limiting and fixing. S3. Installation of pipeline integrated components: According to the pipeline design, insert the lower horizontal keel support components 202 into the corresponding multiple small cylinders 16, and install the pipeline horizontal keel 4 between adjacent lower horizontal keel support components 202; then, according to the pipeline layout requirements, insert the point-type pipe clamps 5 into the elongated holes 11 on the top surface of the pipeline horizontal keel 4 to complete the pipeline fixing structure construction. S4. Laying and Overall Verification of Decorative Materials: Place composite floor decorative material 6 within the rectangular area enclosed by the horizontal keel 3. Use the vertical profile 12 at the top of the horizontal keel 3 to limit the side edges of the decorative material. Finally, check the stability of the connection of each component, the flatness of the ground, and the compliance of the pipeline layout. Make minor adjustments to the deviations to complete the overall structure construction.
